Introduction:
Dysfunctional attitudes about oneself, the world and the future, measured quantitatively by Weissman's Dysfunctional Attitudes Scale (DAS), are thought to influence the onset and persistence of major depressive disorder. However, never-depressed individuals may also harbour latent negative schema which may become activated under stressful conditions, giving rise to dysfunctional negative cognitions.
Objectives:
This study investigated whether everyday psychosocial stresses could be sufficient to activate dysfunctional self-schema and increase negative cognitions in a large group of healthy adolescents and a preliminary cohort of previously depressed adolescents.
Methods:
92 never-depressed adolescents aged 17-19 and 18 previously depressed adolescents, recruited from the Cambridge ROOTS cohort, took either version A or B of the DAS at rest on day 1. On day 2, they were subjected to the Trier Social Stress Test, a psychosocial stress paradigm, 22 minutes after which they took the other version of DAS.
Results:
Stress did not affect the DAS score in either group.
Conclusions:
Brief psychosocial stress does not appear to influence negative assumptions in healthy young adults with or without a past history of depression. It is possible that this is because dysfunctional assumptions, unlike self-schemas, are not latent. More long-term stresses may be needed to activate negative thoughts to a level where risk of depression is increased.
