Reinforcement sensitivity and maternal style as predictors of psychopathology
This study examined the effect of reinforcement sensitivity and adverse parenting on adult psychopathology. One hundred eighty-one undergraduates completed a battery of self-report scales measuring Behavioral Inhibition System (BIS) sensitivity, Behavioral Approach System (BAS) sensitivity, maternal care, maternal overprotection, depression, anxiety, psychopathy, and substance abuse. Hierarchical regression analyses were conducted to test the hypotheses. Higher BIS and lower care scores predicted anxiety and depression; lower BAS, higher BIS, and lower care scores predicted anhedonic depression. Higher BAS and lower BIS scores predicted drug abuse and primary psychopathy; higher BAS, lower BIS, and lower care scores predicted alcohol abuse. Higher BAS and lower care scores predicted secondary psychopathy. Exposure to low maternal care predicted anxiety, depression, alcohol abuse, and secondary psychopathy after partialling out BIS and BAS sensitivity. In addition, some support was found for the hypothesis that BIS sensitivity mediates the effect of maternal overprotection on anxiety. © 2006 Elsevier Ltd. All rights reserved.
