Objectives: Interpersonal difficulties have been implicated in both anxiety and depression. However, much less is known about whether interpersonal difficulties may account for, in part, the high level of comorbidity between mood and anxiety symptoms. This study examined whether various interpersonal difficulties, assessed with the Inventory of Interpersonal Problems, Short Circumplex (IIP-SC), were underlying mechanisms in the relationship between anxiety and depression symptoms in a high-risk sample of late adolescents with clinical levels of anxiety. Methods: 144 late adolescents with clinical levels of anxiety (mean age = 18.63 years; SD = 0.92) reported on their trait anxiety, worry, anxiety and depressive symptoms, and interpersonal problems. Results: Consistent with hypotheses, the IIP-SC overly nurturant subscale partially accounted for the relationship between anxiety and depression. The IIP-SC non-assertive and social avoidant subscales did not significantly account for the anxiety-depression relationship. Conclusions: Findings suggest that interpersonal behaviours characterised by excessive attempts to please and accommodate others may ultimately contribute to our understanding of the anxiety-depression association. We discuss the implications of our findings and how they may be applied to evidence-based assessment and treatment of anxiety problems.
