    Ability of Children with Autism Spectrum Disorders to Identify Emotional Facial Expressions
    Lorenzi, Jill Elizabeth (Virginia Tech, 2012-05-01)
    Previous research on emotion identification in Autism Spectrum Disorders (ASD) has demonstrated inconsistent results. While some studies have cited a deficit in emotion identification for individuals with ASD compared to controls, others have failed to find a difference. Many studies have used static photographs that do not capture subtle details of dynamic, real-life facial expressions that characterize authentic social interactions, and therefore have not been able to provide complete information regarding emotion identification. The current study aimed to build upon prior research by using dynamic, talking videos where the speaker expresses emotions of happiness, sadness, fear, anger, and excitement, both with and without a voice track. Participants included 10 children with ASD between the ages of four and 12, and 10 gender- and mental age-matched children with typical development between six and 12. Overall, both ASD and typically developing groups performed similarly in their accuracy, though the group with typical development benefited more from the addition of voice. Eye tracking analyses considered the eye region and mouth as areas of interest (AOIs). Eye tracking data from accurately identified trials resulted in significant main effects for group (longer and more fixations for participants with typical development) and condition (longer and more fixations on voiced emotions), and a significant condition by AOI interaction, where participants fixated longer and more on the eye region in the voiced condition compared to the silent condition, but fixated on the mouth approximately the same in both conditions. Treatment implications and directions for future research are discussed.

    Access to Autism Spectrum Disorder Services for Rural Appalachian Citizens
    Scarpa, Angela; Jensen, Laura S.; Gracanin, Denis; Ramey, Sharon L.; Dahiya, Angela V.; Ingram, L. Maria; Albright, Jordan; Gatto, Alyssa J.; Scott, Jen Pollard; Ruble, Lisa (2020-01)
    Background: Low-resource rural communities face significant challenges regarding availability and adequacy of evidence-based services. Purposes: With respect to accessing evidence-based services for Autism Spectrum Disorder (ASD), this brief report summarizes needs of rural citizens in the South-Central Appalachian region, an area notable for persistent health disparities. Methods: A mixed-methods approach was used to collect quantitative and qualitative data during focus groups with 33 service providers and 15 caregivers of children with ASD in rural southwest Virginia. Results: Results supported the barriers of availability and affordability of ASD services in this region, especially relating to the need for more ASD-trained providers, better coordination and navigation of services, and addition of programs to assist with family financial and emotional stressors. Results also suggested cultural attitudes related to autonomy and trust towards outside professionals that may prevent families from engaging in treatment. Implications: Relevant policy recommendations are discussed related to provider incentives, insurance coverage, and telehealth. Integration of autism services into already existing systems and multicultural sensitivity of providers are also implicated.

    Acoustic Startle Response in High and Low Hostiles Before And After A Cold Pressor Task
    Klineburger, Philip C. (Virginia Tech, 2011-04-02)
    High-hostiles exhibit exaggerated physiological responses to stressors as seen by increased cardiovascular reactivity (BP & HR) (Rhodes, Harrison, & Demaree, 2002; Demaree & Harrison, 1997). This exaggerated physiological response style is associated with cardiovascular disease and premature death (Everson et al., 1997). This experiment hypothesized that diminished regulatory control would also be evident in the Acoustic Startle Response (ASR). In this experiment, high- and low-hostile undergraduate men (N = 40) were exposed to a series of startle probes before and after a cold pressor (CP). Startle responses were measured using electromyography (EMG) recorded over the orbicularis occuli. Cardiovascular measures of blood pressure and heart rate were also taken. A 2 X 2 mixed factorial ANOVA was performed with Group (high and low hostile) as the fixed factor, Condition (pre and post CP) as the repeated measure, and peak magnitude EMG (mV) of startle responses as the dependent variable. For startle responses, significant main effects for Group and Condition indicated that high hostiles had larger startle responses than low hostiles and startle responses decreased after the cold pressor (CP). A significant Group X Condition interaction effect was found. Post-hoc analyses revealed no significant group differences before the CP. After the CP, high-hostiles had significantly higher startle responses than-low hostiles. High-hostiles' startle responses did not change significantly after the CP, whereas low-hostiles' startle response magnitude decreased significantly after the CP. Low-hostiles HR increased significantly after the cold pressor and both groups SBP decreased significantly after the cold pressor.

    Adjustment to Childhood Chronic Illness: Prediction of Psychological Adjustment with an Investigation into Spiritual Coping
    Boeving, Charmayne Alexandra (Virginia Tech, 2000-11-03)
    Childhood chronic illness is replete with stressors that affect children's functioning across physical, social, emotional, and psychological domains. In this project, efforts were directed toward the identification and assessment of spirituality as a potential addition to the approach-avoidance paradigm of coping response. Twenty-two children diagnosed with either cancer or sickle cell disease were interviewed, along with their mothers, regarding psychosocial adjustment and typical approaches to coping with stressors. Children completed depression, anxiety, and quality of life questionnaires. Child participants were also asked to rate how often they utilized specific spiritual and general coping strategies in the month prior to the assessment. Mothers completed measures of depression and spiritual well-being, as well as parent proxy reports on their children's quality of life and use of spiritual coping. A factor analysis of the spiritual coping measure designed for use in the study (the Spiritual Coping Module) indicated strong support for the theoretically driven factors of religious and existential coping. Children's use of coping did not significantly account for heightened quality of life, nor for the presence of depressive and anxious symptomatology. However, maternal spiritual well-being accounted for 52.5% of the variance in self-reported maternal depression. Results are discussed in the context of improving children's adjustment to chronic illness through increased understanding of the child's and family's pattern of coping responses.

    Anger Expression, Harassment, and Evaluation: Cardiovascular Reactivity and Recovery to Mental Stress
    Vella, Elizabeth Jane (Virginia Tech, 2005-05-10)
    Anger and hostility have been attributed as early risk factors of coronary heart disease (CHD). However, many inconsistencies exist in the literature linking both of these constructs to CHD, as well as to cardiovascular reactivity (CVR) to stressors likely to give rise to CHD. A potential moderating influence discussed in the CVR literature concerns the issue of anger provocation, whereas assessment of the ability to evaluate the source of provocation may moderate the recovery process. The current study adopts a multivariate approach to assess the interactive effects of dispositional anger in predicting the CVR and recovery to mental arithmetic (MA) stress with and without harassment in 47 male undergraduate psychology students. Results revealed anger out (AO) to be associated with high vagal and low frequency power suppression in response to the MA task with harassment. Exposure to experimenter evaluation was associated with attenuated diastolic blood pressure recovery and facilitated vagal recovery in high AO subjects, whereas the opposite pattern was apparent for low AO subjects. The general findings suggest that trait anger interacts with situational influences to predict CVR and recovery to stressors.

    Assessment of Criminal Thinking as a Predictor and Mediator of Behavior Problems in a Community Youth Sample
    Delk, Lauren Annabel (Virginia Tech, 2020-05-14)
    Criminal behavior results in negative, costly consequences for both individuals and society at large. Therefore, researchers have worked to identify variables that predict recidivism, or recurrence of crime. The variables with the strongest predictive power include criminal thinking, personality traits, antisocial peers, and family difficulties, among others. In addition, policy makers and stakeholders are creating interventions which target criminal thinking, to reduce criminal thinking and hopefully reduce future crime. However, little is known about measuring criminal thinking in community youth for the purposes of early intervention and prevention of future behavior problems. Therefore, this study examined a measure of criminal thinking in community youth to examine item-level and measure validity. It also sought to examine if criminal thinking acts as a mediator between other risk factors and subsequent behavior problems. Although some items may need to be revised, results suggested generally good validity for the total score. This study also supports the stability of criminal thinking in community youth, and thus could be used as a measure of change. Finally, results suggest that criminal thinking mediates the relationships between antisocial friends and parenting styles in predicting reactive aggression. The results of the item-level analysis of this study highlight the similarities between psychopathy and criminal thinking. Questions also arise about the relationship between criminal thinking in community youth and more transdiagnostic concepts, such as emotion regulation problems. Overall, criminal thinking appears to be a viable target for assessment and intervention in community youth.

    Associations between Parental Anxiety/Depression and Child Behavior Problems Related to Autism Spectrum Disorders: The Roles of Parenting Stress and Parenting Self-Efficacy
    Rezendes, Debra L.; Scarpa, Angela (Hindawi, 2011-12-13)
    Parents of children with autism spectrum disorders (ASDs) have been shown to experience increases in stress, depression, and anxiety, which are also associated with child behavior problems related to ASDs. Literature-examining potential mechanisms that underlie the relationship of child behavior problems and parental anxiety/depression in this population are scarce. The current study sought to examine the roles of parenting stress and parenting self-efficacy as mediators between child behavior problems and parental anxiety/depression. Using a sample of 134 mothers, these potential mediators were tested. Hypotheses were supported, indicating that parenting stress mediated the relationship between child behavior problems and decreased parenting self-efficacy, and decreased parenting self-efficacy in turn partially mediated the relationship between parenting stress and increased depression/anxiety.

    Autism Spectrum Disorder Traits and Parental Stress: The moderating role of parental self-efficacy
    Factor, Reina (Virginia Tech, 2016-11-10)
    Previous research has established that caregivers of children with Autism Spectrum Disorder (ASD) experience greater levels of parenting stress as a result of unique parenting demands and child problem behavior (Davis & Carter, 2008; Estes et al., 2013). Positive self-concepts, specifically parental self-efficacy (PSE), have been implicated as a buffer to stress in a number of contexts (Cieslak, Benight, & Lehman, 2008). While many studies examine parenting stress in relation to ASD, they often use parent self-report rather than objective measures in a laboratory setting. The present study aimed to further explore the role of PSE in the relationship of parental stress and ASD traits through a biological measure of stress, as well as a parent self-report within a controlled laboratory environment. Forty-two mother and child dyads participated in a validated parent-child interaction task designed to elicit a stressful experience. Mother’s heart rate (HR) and heart rate variability (HRV) were monitored as the physiological measure of stress reactivity. Mothers also self-reported on ASD traits, perceived stress-reactivity, and PSE. Results demonstrated a significant positive main effect for ASD traits on HRV reactivity, and an interaction such that the relationship between ASD traits and HRV reactivity (i.e., more emotional flexibility) was stronger in those with lower PSE. Given the low sample size and subsequent low power, results should be viewed with caution. Considerations of the context of HRV as well as implications for treatment targets and studying parental stress are explored.

    Caregiver-Assisted Social Skills Intervention for Preschoolers with Autism Spectrum Disorder: Examining Caregiver-Child Relationships and Family Functioning in the PEERS® for Preschoolers Program
    Factor, Reina Suzanne (Virginia Tech, 2020-05-26)
    Social impairments characteristic of Autism Spectrum Disorder (ASD) are evident in early childhood and often worsen as an individual matures (Rao, Beidel, and Murray, 2008). Despite the emphasis on early intervention and caregiver training, few evidence-based interventions explicitly address the development of social skills in preschool-aged children with ASD (DeRosier, Swick, Davis, McMillen, and Matthews, 2011; Reichow and Volkmar, 2010) and none appear to actively integrate caregivers into treatment (Reichow, Steiner, and Volkmar, 2012). Research indicates that generalization beyond a social skills group setting might occur by including caregivers (DeRosier et al., 2011). The PEERS® program is an evidence-based caregiver-assisted social skills program for adolescents and young adults (Laugeson and Frankel, 2010) that has recently been extended for preschoolers with ASD. An initial randomized controlled trial (RCT) indicated benefits from the PEERS® for Preschoolers (P4P) program, but did not examine caregiver or family outcomes. Researchers also suggest a bidirectional effect in which the family system is impacted by the child with ASD and in turn, the child with ASD is also affected by the family (Karst and Van Hecke, 2012). This study examined the P4P curriculum with 15 children with ASD and their caregivers and examined feasibility of the intervention as well as child social skills, caregiver competency, confidence, and parenting skills in working with their child, and family functioning in the context of the P4P intervention. Results suggest the feasibility of proof concept of applying the P4P curriculum to young children with ASD and their caregivers. Specifically, this 16-session intervention appears to improve social skills scores in children with ASD, which is maintained 4-6 weeks after treatment, increased scores were noted in caregiver confidence interacting with their children, as well as improved scores in their affect/animation and achievement orientation in interaction styles with their child, and noted improvements in their parenting styles overall score. Therefore, this intervention may have an impact both the child and caregiver in positive ways and these positive results are largely maintained at a follow-up after intervention completion. Future research will need to focus more on the entire family unit, as no changes were noted in the present study, and should examine the specific mechanisms that lead to these positive results regarding child social skills and caregiver interaction styles and confidence. Additionally, more work that adds to making P4P an evidence-based treatment must be at the forefront of future work.

    Challenging frontal lobe capacity using lateralized vestibular stress: A functional cerebral systems approach to a clinical risk for falls
    Carmona, Joseph (Virginia Tech, 2011-10-12)
    A conceptual model was originally proposed that linked the vestibular modality with executive domains by means of a functional cerebral systems framework. The claim was that frontal regions exert regulatory control over posterior systems for sensation and autonomic functions in a dense, interconnected network with right hemisphere specialization. As a preponderance of evidence demonstrates that a design fluency task is often associated with right frontal functioning, it was hypothesized that proficiency on a design fluency task would yield differences in QEEG and skin conductance after vestibular activation. Fifty-eight total (29 high- and 29 low-fluent performers on the Ruff Figural Fluency Test were subjected to 20 whole-body passive rotations about the neuroaxis at a constant rate of approximately 120 degrees per second. EEG and skin conductance levels were recorded prior to and post-rotation. Analyses were conducted on delta (1-4 Hz.) and beta (13-21 Hz.) frequencies. Overall, delta activity increased from baseline to post-rotation with higher levels at frontal sites, however no group differences were found across conditions. Regarding beta activation, high design fluency was associated with increased beta activation at the right temporal site (T6). In contrast to expectations, beta activity diminished from baseline to post-stress over both groups. Skin conductance levels increased from baseline to post-stress. Methodological considerations are discussed regarding gender issues and procedures of the experiment. The results indicate that vestibular disorientation yields systematic delta changes in the frontal regions, but that future refinements to the vestibular stressor may elicit QEEG and skin conductance differences in fluency groups.

    Childhood aggression in schools: The impact of behavioral patterns and contextual influences on teachers' cognitive, affective, and behavioral responses
    Alvarez, Heather Krishna (Virginia Tech, 1999-12-15)
    Despite considerable advances in the development and implementation of school-based interventions, aggressive behavior in schools remains a significant problem for both educators and the community as a whole. The present study was designed to examine possible contextual influences on the course and treatment of aggression in schools, in an effort to inform future intervention development. The aim of the present study was to examine possible influences on teachers' response to reactive and proactive aggression in the classroom, and test the applicability of Weiner's attributional model of motivation and emotion. A sample of 121 middle school teachers completed self-report measures of teaching characteristics, efficacy, stress, and burnout. They also responded to four vignettes of student aggression with measurements of proposed attributions, affective reactions, and interventions. A series of ANOVAs showed that teacher's proposed responses differed as a function of child aggression subtype, teacher stress, burnout, efficacy, and training. Multiple regression analyses were used to test Weiner's theoretical model, as well as consider the moderating influence of teacher characteristics. Findings failed to support the application of Weiner's model to the current sample. Alternative patterns of moderation and mediation were significant, however. Implications of study findings were discussed as they relate to relevant theoretical models and recent advances in clinical and educational research.

    Childhood Emotional Abuse, Effects, and Protective Factors: Comparison of Protective Factors between Emotional and Physical Abuse
    Papafratzeskakou, Eirini (Virginia Tech, 2011-04-29)
    Although emotional maltreatment is clearly a very important issue that impedes youths' development, it has only recently begun to receive the attention it deserves. The present study hypothesized that for adolescents with high self-worth, high religiosity, high parent and peer support, high family cohesion, and low family conflict the negative effects of emotional abuse on internalizing symptomatology would attenuate. Additionally, the same protective factors were hypothesized to moderate the relationship between emotional and physical abuse and adolescent internalizing symptomatology. Two samples were used in order to test the aforementioned hypotheses: 1) a whole sample that consisted of adolescents with no or any emotional and physical abuse (N = 220) and 2) a no physical abuse sample that consisted of adolescents with no or any emotional abuse (N = 118). In order to assess the study variables the following measures were used: Conflict Tactics Scale-PC, Self-Perception Profile, Youth Religiosity Scale, Inventory of Parent and Peer Attachment, Family Environment Scale, and Youth Self Report. None of the study's hypotheses were supported by the current data. It is assumed that this might be due to the sample's nature and it is suggested that future studies utilize a sample with different age groups and with higher reports (means) of emotional and physical abuse. However, the findings suggested that emotional abuse had a stronger effect on internalizing symptomatology than physical abuse, and the significant main effects of self-worth, parent support, peer support, and family cohesion indicated the importance of their presence in adolescents' psychological adjustment.

    Children's Primary Health Care Services: A Social-Cognitive Model of Sustained High Use
    Janicke, David Michael (Virginia Tech, 2001-04-06)
    This study tested portions of a social-cognitive model that explained the mechanisms involved in the parent decision-making process that ultimately drive and maintain children's health care use. Eighty-seven primary caretakers of children ages 4 to 9 years completed measures of child health and behavior, parental stress and functioning, and social cognitive measures related to parenting and health care use. Primary care use data over the two-years prior to recruitment were collected from primary care providers. Regression analysis showed that social cognitive measures were significant predictors of pediatric primary care services. Specifically, parental stress interacted with general parenting self-efficacy; parents with high stress and high parenting self-efficacy were more likely to use pediatric primary care services. Self-efficacy for accessing physician assistance and parental outcome expectations for pediatric physician visits were positively related to pediatric primary care use. These social cognitive variables accounted for more variance than variables traditionally included in health care use research (i.e., child behavior, parental distress, and parent health care use). Best Subsets analysis resulted in an overall best predictive model that accounted for 29.8% of the variance in pediatric primary care use. In this model, the interaction between parental stress and general parenting self-efficacy was the best predictor of use, accounting for 11.5% of the variance in physician use. High internalizing behavior scores, higher self-efficacy for accessing physician assistance, use of medication, and more parent health care visits were associated with higher pediatric primary care use in this overall model. While acknowledging the role of child health and behavior, this study extends the literature by demonstrating the importance of considering parental perceptions of burden, confidence, and ability to help themselves and their family. Implications for health care professionals and directions for future research are discussed in light of these finding.

    Collaborative Design for Young Children with Autism: Design Tools and a User Study
    McCrickard, D. Scott; Abel, Troy D.; Scarpa, Angela; Wang, Yao (Department of Computer Science, Virginia Polytechnic Institute & State University, 2013-09-30)
    This paper provides an overview of a collaborative design effort that involves computer scientists, psychologists, and designers working together to investigate design methods to help in the creation of technology to people with cognitive disabilities. The focus of this effort was in developing techniques to help novice designers create technology interfaces to support anger management in young people with autism spectrum disorder (ASD). The primary output for designers is a card set for which each card has a claim about an anger management technique that can help young people. Design activities leveraging scenarios and personas are suggested that leverage the card set in the creation of technology interfaces. This paper introduces the card set and supporting techniques, describes a design session in an undergraduate classroom setting, and speculates about future directions for this work.

    Comorbid Oppositional Defiant Disorder and Anxiety Disorders in Boys and Girls: Relations to Perceptual Bias
    Halldorsdottir, Thorhildur (Virginia Tech, 2011-02-28)
    The current study examined relations among perceptual bias, measured by comparing self performance ratings to those of an independent rater, and gender and comorbid Oppositional Defiant Disorder and Anxiety Disorder (ODD/AD) status in school-aged children with primary diagnoses of ODD. Specifically, perceptual bias of boys (N=61) and girls (N=39) with ODD with (N=43) and without comorbid AD (N=57) were examined after completing a problem solving activity with their parent(s). Measures of global functioning, executive functioning, and severity of the disorders were also examined. Based on previous findings, it was predicted that boys with ODD without AD would exhibit the greatest positive perceptual bias, followed by girls with ODD without AD, boys with ODD and AD, and, finally, girls with ODD and AD. No significant group differences emerged on the related dimensions of global functioning, executive functioning, or severity of behavioral problems. However, systematic differences in age, ADHD diagnosis, and intellectual ability were revealed among the groups, consequently they were controlled for in the final analyses. Overall, children in all groups displayed positive perceptual bias when compared to observer ratings. However, the main hypotheses were not supported. That is, children with ODD evaluated their performance higher than that of observers, independent of comorbid anxiety and gender, when controlling for the effects of age, ADHD, and intellectual ability. Implications and future directions in examining perceptual bias are discussed.

    Coping Strategies Form Systems that Regulate PTSD Symptoms in Children and Adolescents: Exploring the Regulatory Hypothesis
    Carvajal, Franklin (Virginia Tech, 2007-04-26)
    This study investigated the potential regulatory effects of various coping strategies on Posttraumatic Stress Disorder (PTSD). It first divided PTSD symptoms and selected coping strategies into cognitive, social/motivational, and emotional types. The study then conceptualized each of the preceding types of coping strategies as being controlled stress responses and the PTSD symptoms as being semiautomatic stress responses. It lastly proposed that coping strategies be further divided into activating controlled stress response and deactivating controlled stress response. Controlled stress responses are coping strategies that are consciously initiated and implemented. Semiautomatic stress responses are PTSD symptoms that spontaneously emerge without conscious intent. Activating controlled stress responses consisted of the following coping strategies: seeking understanding, avoidant actions, and expressing feelings. Deactivating controlled stress responses encompassed: positive cognitive restructuring, emotion-focused support, and physical release of emotions. Semiautomatic stress responses entailed: reexperiencing, numbing, and arousal symptoms. It was proposed that cognitive, social/motivational, and emotional activating controlled stress responses would increase corresponding cognitive, social/motivational, and emotional semiautomatic stress responses. In the same vein, it was expected that cognitive, social/motivational, and emotional deactivating controlled stress responses would decrease respective semiautomatic stress responses. To illustrate, it was predicted that with regard to the cognitive regulatory system, its activating cognitive controlled stress response (seeking understanding) would exacerbate the frequency of associated cognitive semiautomatic stress responses (reexperiencing PTSD symptoms) whereas its deactivating cognitive controlled stress response (positive cognitive restructuring) would ameliorate it. Path analyses were conducted on correlation matrices whose elements represented two coping strategies (e.g., an activating controlled stress response: seeking understanding, and a deactivating controlled stress response: positive cognitive restructuring) and one PTSD symptom cluster of the same nature (e.g., the semiautomatic stress response: reexperiencing). Data were obtained from a sample of sixty-four children and adolescents ages 8-18. The coping strategies were assessed via ratings on items included in the How I Cope Under Pressure (HICUPS) instrument and the PTSD clusters through the use of the Diagnostic Interview for Children and Adolescents (DICA). Only one hypothesis was partially supported. It was found that the social/motivational activating controlled stress response (avoidant actions) indeed increased social/motivational semiautomatic stress responses (numbing symptoms).

    Defensive Neurophysiological Response: Exploring the Neural and Autonoic Correlates of Social Behavior
    Patriquin, Michelle Anne (Virginia Tech, 2013-04-01)
    Current literature suggests neurological (i.e., insula, amygdala) and autonomic (i.e., respiratory sinus arrhythmia; RSA) markers of language, social, and behavioral challenges in autism spectrum disorders (ASD; Bal et al., 2010; DiMartino, Ross, et al., 2009; Lorenzi, Patriquin, & Scarpa, 2011; Patriquin, Scarpa, Friedman, & Porges, 2011), that hypothetically reflect a defensive neurophysiological circuit (i.e., hyper-arousal within the central and autonomic nervous systems). It is unknown how this neurophysiological state contributes to difficulties in ASD. Therefore, the current study quantified peripheral and central nervous system activity and investigated how this neurophysiological circuit may be related to different social and behavioral patterns that characterize ASD. Participants with (n = 16) and without (n = 30) ASD listened to classical music while brain (via functional magnetic resonance imaging) and autonomic (via pulse oximeter and plethysmogram) data were collected. Results indicated that decreased insula and amygdala activity during physiological hyper-aroused states predicted symptoms associated with ASD, and predicted higher levels of comorbid anxiety, stress, and depression. Contrary to hypotheses, no baseline RSA or amygdala differences were noted between ASD and controls groups, suggesting that adults with ASD may have developed effective coping strategies for reducing physiological threat responses. It will be important for future studies to continue to explore and clarify the neural connections of peripheral nervous system activation in individuals with and without ASD, including extending this research to children.

    Development and Testing of a Primary Tier Social Skills Program: Effects for Children with Exceptionalities
    Ostmeyer-Kountzman, Katrina Francine (Virginia Tech, 2014-06-12)
    School-wide positive behavior support (SWPBS), a tiered prevention model targeted at making educational environments safe and effective, is swiftly gaining popularity in the United States (Brandt, Chitiyo, May, 2012). This model aims to teach prosocial behavior through positively stated rules and expectations; however, there is little research examining social skills instruction using a tiered model (Schoenfield, Rutherford, Gable, Rock, 2008). This is of considerable concern for children with autism spectrum (ASD) and related social disorders as educators attempt to address the social needs of these students within a SWPBS framework (Sansoti, 2010). The current study aimed to begin exploration into the topic of a tiered social skills training framework for children with autism spectrum and related social/behavioral disorders and their typically developing peers by initial implementation and testing of a primary tier social skills program through the use of a mixed model research design. The program was implemented in two classrooms (1 preschool and 1 kindergarten) in southwest Virginia. A mixed-method research study was conducted to determine whether the program leads to improved classroom environment, improved social functioning for children with ASD or social difficulties (n=8), what qualities of children, teachers, and classrooms affect implementation and results, and what additional changes or elements need to be provided to implement the program without the aid of a researcher. While quantitative results failed to yield significant findings, qualitative results partially supported the use of the program. While the initial results were small to insignificant, they point to important considerations for further refinement of the program.

    Diatheses to Depression: The Interactions of Schema Propositions, Schema Structure, and Negative Life Events
    Cankaya, Banu (Virginia Tech, 2006-03-13)
    Drawing from the meta-construct model of cognition (Ingram, 1984; Ingram & Kendall, 1986), the goal of the present study was to examine whether the structural (i.e., self-complexity; SC, Linville, 1985) and propositional components of schemas (dysfunctional attitudes; DAS, Weissman & Beck, 1978), independently and in interaction with each other and stressors, lead to changes in depressive symptoms. The prediction was that if negative self-attributes across different self-aspects in a specific domain, interpersonal or achievement, are highly distinct (i.e., high negative SC) or if positive self-attributes across different aspects of self are redundant (i.e., low positive SC), then the DAS would be more likely to lead to higher levels of depression when domain-congruent stressors occur. To test the main effect, two-way interaction, and three-way interaction hypotheses, the present study used a two month longitudinal design involving three assessment periods, separated by one month. At the baseline, a total of 189 students participated in the study. Of these students, 163 and 121 students participated in the first and second follow-ups, respectively. Multiple hierarchical regression analyses were used to examine two-way and three-way interactions. Results showed strong support for the predictive power of negative SC with respect to depressive symptomatology. The DAS, on the contrary, was a concurrent factor related to depressive symptoms. Further, the present study did not provide supportive evidence for the diathesis-stress model of depression. Although contradicting expectations, the pattern of relationships between interpersonal negative SC, DAS, distal stressors suggested promising venues for future research.

    Differential Efficts of Hostility on Frontal Lobe Performance: A dual task approach with Fluency and Cardiovascular Regulation
    Williamson, John Bonar (Virginia Tech, 2000-08-03)
    The influence of levels of hostility on the lateralized tasks of verbal and nonverbal fluency, and the concurrent cerebral regulation of autonomic nervous system functioning was examined. Forty-eight right-handed males were recruited for participation with half classified as low-hostile and the other half as high-hostile. Previous research has shown that high-hostile males, at rest, have greater right hemisphere arousal relative to low-hostile males. It was predicted that this heightened, at rest, arousal would lead to reduced capacity to perform right hemisphere lateralized proximal tasks simultaneously. Two commonly used neuropsychological tests sensitive to left and right anterior cerebral systems are the Controlled Oral Word Association Test and the Ruff Figural Fluency Test (RFFT) respectively. Nonverbal fluency, verbal fluency, and perseverative errors were assessed using these measures. Cardiovascular measures of systolic and diastolic blood pressure, and heart rate were assessed using oscillometric technique with a digital blood pressure meter. A dual-task methodology was used to evaluate these anterior and posterior cerebral systems simultaneously. Since cardiovascular regulation and nonverbal fluency are both right-frontal tasks, it was predicted that high hostile men would evidence increased interference on cardiovascular regulation concurrent with the nonverbal fluency task in comparison with low hostile men. It was also predicted that high-hostile males would display more perseverative errors than low- hostile males on the nonverbal fluency task as a function of regulatory interference. The results supported a capacity-limited prediction in high-hostile males. High-hostile males evidenced significantly heightened systolic blood pressure responses during the nonverbal fluency task in comparison with low hostile males. Further, high-hostile males displayed more perseverative errors in nonverbal fluency than did the low-hostile males. No differences were found in the overall fluency scores (verbal or nonverbal). These results partially support the expectation that differences exist between high and low hostile males for right frontal functioning. Moreover, these differences manifest in multiple domains of associated right frontal functioning. These findings extend the evidence for the proposed anterior-posterior inhibition model of hostility.
