5-year follow-up of adolescents with social anxiety disorder: Current functioning during COVID-19
Carlton, Corinne N.; Garcia, Katelyn M.; Honaker, Makayla; Richey, John A.; Ollendick, Thomas H. (Elsevier, 2023-04)
The present study followed-up adolescents with social anxiety disorder (SAD) during the COVID-19 pandemic, approximately 5-years following their participation in an Attention Bias Modification Training (ABMT) program (Ollendick et al., 2019). The current study aimed to evaluate current functioning and quality of life (QoL) during the emerging adulthood period. Participants included 27 young adults who completed a randomized controlled trial of ABMT and were available for follow-up. Participants filled out self-report measures of QoL and functioning and underwent a clinical interview to assess current severity of social anxiety. Clinician-rated symptoms of SAD significantly decreased from post-treatment to 5-year follow-up. Additionally, results demonstrated that social anxiety severity was significantly related to poorer self-reported physical and psychological health as well as poorer functioning with regard to social distancing fears during COVID-19. Lastly, when evaluating change in symptoms over time, increases in social anxiety severity over a 5-year period significantly predicted worsened social distancing fears during COVID-19.
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.
Adventure-Based Therapy and Self-Efficacy Theory: Test of a Treatment Model for Late Adolescents with Depressive Symptomatology
Richardson, Elizabeth DeHart (Virginia Tech, 1998-11-18)
The primary objective of the current study was to propose and test a model for conceptualizing changes that occur as a result of adventure-based therapy (ABT), using self-efficacy theory as the conceptual foundation. Other objectives were to test the effects of ABT on depressive symptomatology and related psychosocial variables (e.g., anxiety, self-esteem). One-hundred and nine college freshmen participated in the screening procedure. Subjects who indicated mild to severe depressive symptomatology on a self-report measure and did not report past history of trauma were invited to participate in the study. Forty-one individuals were randomly assigned to either the adventure-based therapy (ABT) condition (i.e., a one-day ropes course experience) or to a placebo-control condition (i.e., an extended walk outdoors in a group). Subjects were divided into two cohorts, each with treatment and control groups, because of safety requirements related to capacity on the ropes course. Self-report instruments were completed immediately prior to participation (i.e., pretest), immediately following participation (i.e., posttest), and at 2-weeks and 2-months post participation. Primary multivariate analyses of variance performed on state and trait dependent measures did not yield statistically significant interactions; therefore, results indicated that ABT may not significantly decrease depressive and anxious symptomatology in late adolescents with depressive symptomatology. However, data were further analyzed for exploration in light of the generally low statistical power and group differences suggested by graphic displays of data. Exploratory analyses suggested that ABT may increase efficacy for coping with anxiety created by novel situations and efficacy for working and problem-solving in a group. It was therefore suggested that self-efficacy theory warrants further consideration as a theoretical framework for explaining changes that occur as a result of ABT. In addition, exploratory analyses suggested that ABT may also reduce anxiety and general psychological distress. Finally, depressive symptomatology decreased for individuals in the ABT treatment group and the placebo-control group according to exploratory analyses; however, there were no differences between groups. Further exploration of the potential effects of ABT on depressive and anxious symptomatology and general psychological distress is warranted.
An Analysis of Adherence in Childhood Diabetes: Social Learning and Family Systems Variables
Lilly, Mary Kristine M.S. (Virginia Tech, 1998-03-30)
The purpose of the current study was threefold: 1) to assess youths' and parents' perceptions of their competency in managing diabetes, 2) to assess family flexibility and cohesiveness, and 3) to assess the utility of self-efficacy and family factors as predictors of adherence and metabolic control. Participants included 62 youths with insulin-dependent diabetes mellitus (IDDM) and their parents. Parents' and youths' perceptions of their abilities in diabetes and related situations, family cohesion and adaptability, and perceptions of the family's ability to integrate the demands of the diabetes regimen into general family routines were assessed. Results suggested that both social learning factors and general family relations were important in the prediction of youths' adherence to the treatment regimen for diabetes and metabolic control. Moreover, family efficacy and family cohesion were related, suggesting the need for models of assessment and intervention that include both social learning and general family functioning variables.
Analysis of Quantitative Electroencephalographic and Cardiovascular Responses to Stress Amoung Low- and High-Hostiles
Demaree, Heath Allan (Virginia Tech, 1997-04-16)
This experiment was primarily designed to identify higher cortical correlates of cardiovascular arousal. Low- and high-hostile, right-handed, undergraduate men were identified using the Cook Medley Hostility Scale (CMHS). All participants (N = 30) completed the cold pressor paradigm. Cardiovascular (heart rate, systolic blood pressure, and diastolic blood pressure) and electroencephalographic (beta magnitude) data were collected before and after the stressor. As predicted, high-hostiles showed greater increases of heart rate and systolic blood pressure to the stressor relative to low-hostiles. The primary findings of this research include significantly greater beta magnitude recorded by the T3, relative to F7, electrode among low-hostiles. This may suggest that low-hostiles experience left-frontal disinhibition of left-temporal regions, thereby strengthening cardiovascular regulation during the cold-pressor stress. In addition, irrespective of condition, high-hostiles evidenced significantly greater beta magnitude at regions corresponding to the F7 and F8 electrodes. This perhaps suggests that high-hostiles have a relative inability to increase their rostral modulation of posterior systems related to cardiovascular activity/regulation. Low- and high-hostiles did not, however, evidence reliable differences in their ability to monitor cardiovascular arousal to the cold-pressor stress. Findings are discussed in terms of a systems approach, and pertinent future research is recommended. This research did not support the prominent neuropsychological theories of cardiovascular regulation proposed by Heilman et al. (1993) and Tucker and Williamson (1984). Rather, the results may suggest that right- and left-cerebral mechanisms may be primarily responsible for sympathetic and parasympathetic cardiovascular arousal, respectively.
Anxiety and depression in children and adolescents: an examination of cognition and attributional style
Byrd, Devin A. (Virginia Tech, 1996-12-06)
The relationship of attributional style to anxiety and depression in children and adolescents has received little attention in comparison to studies conducted with adult populations. However, preliminary studies suggest that children and adolescents evidence similar attributional style patterns to those expressed by adults. This study further examines the relationship of anxiety and depression to attributional style to determine the utility and applicability of the adult model to children and adolescents. In addition, this study examines the accuracy of obtaining attributional style ratings using hypothetical events (i.e., questionnaire method) versus real-life events. Further, this study was designed to study the relationship of emotional measures of anxiety and depression (Le., Children's Depression Inventory and Revised Children's Manifest Anxiety Scale) versus cognitive measures of anxiety and depression (Negative Affect Self-Statement Questionnaire). It was hypothesized that real life events (as measured by the Specific Life Events Schedule; SLES) would prove to be a concurrently valid measure of attributional style in relation to hypothetical events presented through a questionnaire method (as measured by the Children's Attributional Style Questionnaire; CASQ). As well, it was predicted that real life events of the SLES would prove to be a more accurate measure of attributional style than hypothetical life events of the CASQ, in relation to achieved depression scores. Furthermore, it was predicted that certain indices of attributional style and negative self-statements would prove to be significant predictors of depression (as measured by the CDI) and anxiety scores (as measured by the RCMAS).
Anxiety and depression: The moderating roles of self-perception and race
Fraire, Maria G. (Virginia Tech, 2010-04-14)
It has been shown that children with elevated anxiety levels are at a higher risk for developing depressive symptoms (e.g., Seligman & Ollendick, 1998). Furthermore, it has been shown that high self-worth may serve as a protective factor against developing both anxiety and depressive symptoms (e.g. Costello et al., 2008). The primary focus of the current research was to evaluate the moderating role that self-worth played in the predictive relationship between anxiety and depression. A second avenue of interest for the current research was the exploration of the role that race played in these predictive relationships between anxiety, depression, and self-worth. Using an ethnically diverse sample of 726 middle school children regression analyses were run to examine the predictive relationship between anxiety symptoms and depressive symptoms, as well as the potential moderating role of self-worth. Additionally, a three way interaction was examined between gender, racial group, and anxiety in the prediction of depressive symptoms. Analyses showed that both self-worth and anxiety symptoms were significantly related to depressive symptoms. However, self-worth and race were not moderating variables in the relationship between anxiety and depression. Furthermore, there was not a significant three way interaction between gender, racial group, and anxiety in the prediction of depression. The discussion includes an examination of the limitations as well as possible future directions for research.
ASD Traits, Social Competence, and Co-Occurring Psychopathology: The Moderating Role of Gender
Kreiser, Nicole L. (Virginia Tech, 2014-03-26)
The higher occurrence of autism spectrum disorder (ASD) and sub-threshold autistic traits in males, relative to females, has been consistently documented in the literature (e.g., Fombonne 2003, 2005). In addition to potential biogenetic mechanisms, there is some evidence suggesting that differences in the behavioral manifestation of ASD symptoms and co-occurring psychopathology may play a role in the differential prevalence of ASD in males and females (e.g., Holtmann, Bolte, and Poustka, 2007; Lai et al., 2011; Solomon, Miller, Taylor, Hinshaw, and Carter, 2012). In this two-phase study, we sought to examine potential gender differences in the relationship between behaviorally defined ASD traits and observable social impairment and co-occurring psychopathology, in a non-clinical sample of young adults. It was hypothesized that gender would moderate the relationship between ASD traits and observed social impairment and co-occurring psychopathology, such that ASD traits would be related to greater levels of observed social impairment for males, and that ASD traits would be related to greater levels of co-occurring psychopathology for females. In Phase I, 1039 undergraduate students participated in an online survey on general psychopathology and ASD traits. From this sample, a subgroup (n = 79) completed Phase II, an in-lab study that included a clinical interview and behavioral observation. ASD traits were not predictive of observed social impairment over and above the effects of social anxiety in this sample, regardless of gender. Although males and females in the sample did not differ on severity of ASD traits, when controlling for the effect of social anxiety, females were rated as more socially competent than males. ASD traits more strongly predicted screening positive for mood disorders in females than in males. Implications regarding ASD traits, as related to social impairment and co-occurring psychopathology in females are discussed.
Assertiveness in boys: evaluating the construct using template matching procedures
Weist, Mark D. (Virginia Tech, 1988-08-15)
The present investigation expanded on the template matching approach (Cone, 1980) to empirically evaluate whether assertiveness is associated with interpersonal success among a group of fourth grade boys. Using popular sociometric status as an index of success in interaction, the performances of 15 popular boys were compared with those of 15 rejected boys in a role-play measure of social behavior. An observation code containing behaviors traditionally associated with assertiveness was compared to a code containing inductively generated behaviors. Popular boys demonstrated significantly higher levels of traditional and inductive behaviors. Total scores on the inductive behavioral, code correlated significantly with self-reported assertiveness, while total scores on the traditional code did not. On an evaluative measure of assertive, aggressive and submissive response alternatives, the two groups showed no significant differences. The utility of the template matching method in empirical target selection and validation was underscored.
Assessing and remediating altered reinforcement learning in depression
Brown, Vanessa (Virginia Tech, 2018-07-06)
Major depressive disorder is a common, impairing disease, but current treatments are only moderately effective. Understanding how processes such as reward and punishment learning are disrupted in depression and how these disruptions are remediated through treatment is vital to improving outcomes for people with this disorder. In the present set of studies, computational reinforcement learning models and neuroimaging were used to understand how symptom clusters of depression (anhedonia and negative affect) were related to neural and behavioral measures of learning (Study 1, in Paper 1), how these alterations changed with improvement in symptoms after cognitive behavioral therapy (Study 2, in Paper 1), and how learning parameters could be directly altered in a learning retraining paradigm (Study 3, in Paper 2). Results showed that anhedonia and negative affect were uniquely related to changes in learning and that improvement in these symptoms correlated with changes in learning parameters; these parameters could also be changed through targeted queries based on reinforcement learning theory. These findings add important information to how learning is disrupted in depression and how current and novel treatments can remediate learning and improve symptoms.
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.
Assessment of Panic Frequency: Reliability and Validity of a Timeline Follow-Back Method
Nelson, William Andrew (Virginia Tech, 2004-04-14)
Given the central role of panic attacks in the diagnosis of panic disorder, an adequate measure of panic attacks is essential. Panic frequency is routinely assessed either by simply asking individuals to estimate the number of panic attacks experienced during a given time in a questionnaire or assessment interview or by having them continuously self-monitor. Panic frequency obtained by such methods is unreliable and invalid or time-consuming, respectively. The purpose of this project was to investigate the reliability and validity of a Panic Attack Frequency Calendar (PAFC), modeled after a time-line follow-back (TLFB) procedure (e.g., Sobell & Sobell, 1979) that has been used for years to reliably and validly assess daily alcohol use through self-report over extended periods of time. The participants consisted of 74 adult individuals (ages 18-57) who indicated that they had experienced a panic attack within the past two weeks. Participants completed a battery of self-report questionnaires, including a retrospective frequency measure, and administered an 8-week PAFC. Participants were then randomly divided into either a self-monitoring group that recorded information in a diary about any panic attacks that they experienced over the following two weeks or a non-self-monitoring control group. All participants were administered another retrospective frequency questionnaire and a 10-week PAFC two weeks after the administration of the first PAFC. Reliability was determined from the two-week stability estimates across the PAFCs for the eight-week period that overlapped both assessments. This was done with several composite panic behavior variables; daily and weekly test-retest reliabilities were also calculated. Concurrent validity was established by comparing panic frequency from the PAFC with that obtained from the diary and the retrospective frequency measure. Further validity was established via correlating the PAFC with the self-report questionnaires. Results are discussed in light of their implications for the assessment of panic attacks.
Assessment of the correlates of sociometric status in children: behavioral, cognitive, peer perception and age differences
Meador, Alice E. (Virginia Polytechnic Institute and State University, 1985)
Sociometric status in childhood, despite its predictive validity, remains determinants.The relatively poorly understood construct with regard to its aim of the present study was to attempt a better understanding. Like most research studies, for every question answered, several were raised. Results of the present study indicated that, undoubtedly, an interaction of factors relate to sociometric standing. These include behavioral and cognitive skills as well as personal attributes such as athletic ability and physical attractiveness. The direction of these relationships remains unanswered. Exemplary of this causal confusion is the finding from this and other studies of a positive relationship between various cognitive social skills and popularity. This relationship has been demonstrated most reliably with withdrawn children. However, it is unclear whether cognitive skill deficits discourage interaction or whether reluctance to engage in social interaction impedes the development of social understanding. With this, as with other variables, it is likely best represented as a transactional model. Hence, acceptance by peers for whatever reason encourages, through social reinforcement, continued pursuit in that and other dimensions which, in turn, facilitate increased skill. Further, the importance of many of these dimensions varies with age and sex. Results of the present study partially replicated previous findings of the importance of peer behavior to sociometric status. However, the finding of a positive relationship between popularity and peer initiated negative interactions underscored the importance of differentiating rejected and neglected subgroups of unpopular children. For treatment studies, the accurate identification of these subgroups as well as the development of different treatment programs for withdrawn versus aggressive children is indicated. Although the results of the present study indicated that unpopular children, as a whole, demonstrated poorer skills in social perception, findings from previous studies, coupled with the small magnitude of difference in present findings, suggest that these skills may vary according to the type of unpopular child. Further, it appears that the importance of these cognitive skills is age dependent. Future research in the area of sociometric status should continue to focus on the identification of behaviors, cognitive skills, and personal attributes associated with peer popularity. Rejected and neglected children should be considered as significantly different subgroups of unpopular children. Finally, it is recommended that future research focus on developing more refined and standardized procedures for measuring affective social perception skills since this appears to be a fruitful and relatively unexplored area in relation to sociometric status.
Associations between Fear of Negative Evaluation and Covert and Overt Attention Bias Through Eye-Tracking and Visual Dot Probe
Capriola, Nicole N. (Virginia Tech, 2018-03-26)
Social Anxiety Disorder is characterized by irrational and persistent fears of potential evaluation and scrutiny by others. For socially anxious youth, the core, maladaptive cognition is fear of negative evaluation (FNE). Whereas Cognitive Behavioral Therapy (CBT) targets remediation of intense and unfounded FNE, Attention Bias Modification Treatment (ABMT) targets attention bias. The degree to which FNE and biased attention are related processes is unknown. This study sought to assess the relationship between FNE and two indices of attention bias (dot probe and eye-tracking). In addition, this study examines differences in attention bias between a clinically confirmed group of youth SAD and healthy controls. A significant group difference in average latency to fixate on angry faces was found [F(1,65) = 31.94, p < .001, ηp2 = .33]. However, the pattern was not consistent across the other attention bias metrics (i.e., dot probe bias scores and first fixation direction percentage towards angry faces). In addition, associations between FNE and the attention bias metrics were not statistically significant in either group. Future directions and implications of these findings within the context of refinements to existing interventions are discussed.
Attention Modification to Attenuate Facial Emotion Recognition Deficits in Children with ASD
Wieckowski, Andrea Trubanova (Virginia Tech, 2019-02-04)
Prior studies have identified diminished attending to faces, and in particular the eye region, in individuals with Autism Spectrum Disorder (ASD), which may contribute to the impairments they experience with emotion recognition and expression. The current study evaluated the acceptability, feasibility, and preliminary effectiveness of an attention modification intervention designed to attenuate deficits in facial emotion recognition and expression in children with ASD. During the 10-session experimental treatment, children watched videos of people expressing different emotions with the facial features highlighted to guide children's attention. Eight children with ASD completed the treatment, of nine who began. On average, the children and their parents rated the treatment to be acceptable and helpful. Although treatment efficacy, in terms of improved facial emotion recognition (FER), was not apparent on task-based measures, children and their parents reported slight improvements and most parents indicated decreased socioemotional problems following treatment. Results of this preliminary trial suggest that further clinical research on visual attention retraining for ASD, within an experimental therapeutic program, may be promising.
An Attention-Specific Intervention for Adults with ADHD
Francisco, Jenifer (Virginia Tech, 2006-05-09)
Attention deficit-hyperactivity disorder (ADHD) consists of symptoms of both inattention and hyperactivity/impulsivity that cause significant functional impairment (APA, 1994). Approximately 4.7% of adults are diagnosed with ADHD; however, there are few empirically-informed interventions that are specifically designed for adults. Instead, many of the common interventions for adults are derived from work done with children with ADHD and may not be appropriate for their particular needs (Weiss & Weiss, 2004). Given that adults with ADHD typically experience more symptoms of inattention rather than hyperactivity, an investigation of the effectiveness of an intervention that specifically targets their inattentive symptoms is warranted (Weiss & Weiss, 2004; Weiss et al., 2002). Therefore, the goal of this study was to evaluate the efficacy of an attention-specific intervention for adults with ADHD. The intervention used in this study, Attention Process Training (APT; Sohlberg & Mateer, 1987), has never been applied to adults with ADHD. The underlying assumption behind this intervention is that attentional functioning can be improved through the use of tasks that are designed to re-train various aspects of attention. More specifically, this study addressed sustained, alternating, and selective/divided attention during the intervention. A non-concurrent multiple baseline design was used in order to assess the effectiveness of the APT among a sample of adults with ADHD. A sample of four adults, aged 21-37 years (M = 27.75) participated in this study and demonstrated minimal changes in their attentional ability after the intervention. In addition, the findings suggest that the different components of attention addressed in this intervention are not distinct and likely have a reciprocal affect on one another.
Attributional patterns as predictors of task-associated anxiety
Camp, Glenda F. (Virginia Polytechnic Institute and State University, 1986)
The present study was designed to examine attributional patterns as predictors of task-associated anxiety. The attribution model suggests that confirmation or disconfirmation of expectancy determines attributional patterns. Consistency between expectancy and performance results in stable attributions for performance, while inconsistency results in unstable attributions. Expected failure attributed to stable factors was proposed to result in greater task-associated anxiety than unexpected failure attributed to unstable cause. In the present study, one hundred and thirty-three undergraduates were assigned to one of four groups (in one of two task areas—mathematics and English) following assessment of attributional patterns, performance, and task-associated anxiety. Group 1 Expect Failure Failure Performance Group 2 Expect Failure Success Performance Group 3 Expect Success Success Performance Group 4 Expect Success Failure Performance Expectancy for failure was determined by an expected grade less than the subject-defined success grade. Expectancy for success was determined by an expected grade greater than or equal to the subject-defined success grade. Success/failure performance was determined by the acceptability or unacceptability of the actual grade. No substantial support was found for the attribution model. In conclusion, results were discussed in terms of methodological and measurement limitations. Implications for the failure to find the predicted results were discussed in terms of these limitations and the expanded attributional model.
Autism Assessment from Home: Evaluating the Remote Childhood Autism Rating Scale, Second Edition (rCARS2) Observation for Tele-Assessment of Autism
Bertollo, Jennifer Rose (Virginia Tech, 2024-05-17)
Since the start of the COVID-19 pandemic, tele-based methods of autism assessment have been relied upon to a previously unparalleled degree; however, the need for such advancements is not new. Observation-based measures are a crucial component of face-to-face autism diagnostic evaluations, but few validated observation tools exist for remotely assessing autism across childhood, particularly for older children and adolescents, providing minimal guidance in this arena. Sanchez and Constantino (2020) previously validated a brief, face-to-face, clinician-facilitated observation coded according to the Childhood Autism Rating Scale, Second Edition (CARS-2). During the pandemic, this measure was adapted as a remote observation (rCARS2 Observation), but has yet to be validated in this format. The current study validated the rCARS2 Observation against the "gold-standard," in-person Autism Diagnostic Observation Schedule, Second Edition (ADOS-2). In this sample of 30 children ages 1.97 to 16.66 years (M = 7.35, SD = 4.00), ADOS-2 and rCARS2 Observation total scores were highly correlated (ρ = .644, p < .001). Receiver operating characteristic (ROC) curves optimized rCARS2 Observation cutoff scores to maximize sensitivity and specificity in predicting possible diagnostic classification (88.9% sensitivity, 80% specificity) and ADOS-2 classification (83.3% sensitivity, 70.6%, specificity). At optimal cutoffs, the rCARS2 Observation predicted the correct diagnosis in 82.8% of cases and the same classification as the ADOS-2 in 75.9% of cases. Validation of this instrument provides support for an accessible and efficient remote autism observation. This is crucial in ensuring uniform training and clinical procedures for tele-assessment of autism, to help mitigate long-standing barriers to service access (e.g., geography, cost, availability).
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.
Barriers to Adherence to Medical Recommendations Following Pediatric Injury
Ramsdell, Katharine Alexis (Virginia Tech, 2016-07-18)
Adherence to treatment recommendations following medical care for pediatric conditions is critically important for promoting optimal physical and psychological well-being. While it has been a focus of many studies across pediatric chronic illness populations, there is a dearth of research examining adherence following pediatric unintentional injury. Empirical evidence from studies with pediatric chronic illness samples indicates that youth experience a number of barriers to adherence to medical recommendations. Adherence is especially difficult for adolescents due to the unique challenges of this developmental period. A mixed methods research approach was utilized to gain a holistic understanding of potential psychological barriers to adherence following adolescent injury. Quantitative analyses examined the potential predictive roles of adolescent psychological [i.e., posttraumatic stress (PTSD), depression, quality of life] and relational (i.e., parent PTSD and depression) factors on adherence. Results of analyses were insignificant; thus, qualitative data was collected to deepen the understanding of barriers to adherence. Findings from qualitative data analyses suggested that a number of barriers to adherence to treatment recommendations exist, including: concern of pain medication addiction, competing activities, treatment side effects, health status, desire for autonomy, and symptoms of depression. Results of qualitative analyses also revealed the presence of additional factors that could facilitate adherence to treatment recommendations. Taking into consideration findings from both quantitative and qualitative analyses, adherence may be best conceptualized as a result of a dynamic decision-making process influenced by numerous interacting factors. This study is the first to examine barriers to adherence among adolescents following unintentional injury and provides an initial roadmap for understanding the mechanisms involved in this complex process.
