A model of BIS/BAS sensitivity, emotion regulation difficulties, and depression, anxiety, and stress symptoms in relation to sleep quality.

Recent research has indicated that interactions between behavioral inhibition system (BIS)/behavioral activation system (BAS) sensitivity and emotion regulation (ER) difficulties increases risk for psychopathology. Considering sleep quality (SQ) has been linked to emotion regulation difficulties (ERD) and psychopathology, further investigation of a possible mechanism is needed. The current study examined associations between BIS/BAS sensitivity, ERD, and SQ to depression, anxiety, and stress symptoms in an undergraduate sample (n=459). Positive relationships between BIS sensitivity and both ERD and stress symptoms, and negative relationships between BAS-reward sensitivity and both ERD and depression symptoms were observed. Furthermore, ERD were positively related to depression, anxiety, and stress symptoms. Succeeding analyses revealed differential relationships between ERD and depression, anxiety, and stress symptoms among good quality and poor quality sleepers. The findings are discussed within the context of personality dimensions and self-regulatory mechanisms, along with implications for the treatment of depression, anxiety and sleep difficulties.
