- Diatheses to Depression: The Interactions of Schema Propositions, Schema Structure, and Negative Life EventsCankaya, 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.
- Psychosocial Factors, Maladaptive Cognitive Schemas, and Depression in Young Adults: An IntegrationCankaya, Banu (Virginia Tech, 2002-05-06)The present study examined a psychosocial-cognitive model that integrates recent findings on the independent effects of early maladaptive cognitive schemas (EMSs; Young, 1994) and psychosocial factors/stressors; viz., social support, expressed emotion, stressful life events and daily hassles, on level of depressive symptoms in young adults. Consistent with Beck's theory of depression, the expectation was that individuals with the EMSs would be more likely to respond to psychosocial stressors with higher levels of depression. Questionnaires measuring the selected psychosocial factors and EMSs were administered to 244 (82 male and 162 female) undergraduate students, mean age 19. Previous findings on the direct relationships between stressful life events, social support and EMSs, and level of depression were replicated. Except for daily hassles, the moderator role of the EMSs was largely disconfirmed when a conservative statistical test (Bonferroni correction) was applied to moderator analyses. With regard to perceived social support received from family and friends, present results were promising for the moderator effect of the EMSs of self sacrifice, functional dependency/incompetence and abandonment. The prediction equation to the criterion of depression indicated independent contributions of stressful life events, and the EMSs of abandonment, functional dependency/incompetence, and insufficient self control, accounting for half of the variance in depression. Taken together, the present data provided little support for the moderator effect of the EMSs rather supported Young's theory (1990) that maladaptive cognitions in themselves can produce increased levels of depression regardless of the presence of triggering stressors.
