Family environment moderates the relation of sluggish cognitive tempo to attention-deficit/hyperactivity disorder inattention and depression.

Abstract

The current study investigated whether a maladaptive family environment would moderate the strength of the relations of sluggish cognitive tempo (SCT) to attention-deficit/hyperactivity disorder inattention (ADHD-IN) and to depressive symptoms in a large sample of college students. Participants (n = 3,172), between the ages of 18-29 (M ± SDage = 19.24 ± 1.52; 69.8% women; 80.4% White) and enrolled in five universities in the United States completed self-report measures of symptomatology, interparental conflict, and family expressiveness of emotions. A negative emotional climate strengthened relations of SCT with ADHD-IN and depressive symptoms. Moreover, the lack of a positive emotional climate strengthened the co-occurrence of SCT with depressive symptoms, though not with ADHD-IN. The current study is the first to demonstrate that the family environment moderates the association between SCT and co-occurring symptomatology in young adults.
