Abstract
OBJECTIVE: This study aimed to investigate the effects of changes in interpersonal cognitions on outcome during cognitive behavioral therapy (CBT) for generalized anxiety disorder (GAD) and how these effects are moderated by patients' interpersonal problems at intake.
METHOD: A sample of 80 adult patients diagnosed with GAD who were undergoing CBT within a randomized controlled trial completed a questionnaire concerning interpersonal problems at baseline as well as measures of changes in interpersonal and self-related cognitions and in worry severity session by session. We conducted dynamic structural equation modeling to estimate cross-lagged within-patient effects of changes in interpersonal cognitions on worry, adjusting for the effects of self-related cognitions. Furthermore, we included interpersonal problems as a moderator of the effects of changes in interpersonal cognitions.
RESULTS: We found significant cross-lagged effects of changes in both interpersonal cognitions and self-related cognitions on subsequent worry levels. Greater changes in interpersonal cognitions and self-related cognitions in a given session were associated with lower worry levels at the beginning of the next session. When adjusting for self-related cognitions, the effects of changes in interpersonal cognitions on subsequent worry remained significant. However, there were no interactive effects of changes in interpersonal cognitions by patients' interpersonal problems on worry severity.
CONCLUSIONS: The results present evidence supporting changes in interpersonal cognitions and self-related cognitions as relevant change mechanisms in CBT for GAD.
