Psychological maltreatment is an important social and public health problem and associated with a wide range of short and long-term outcomes in childhood to adulthood. Given the importance of investigating mitigating factors on its effect, the purpose of the present study is to investigate the mediating effect of active and avoidant coping strategies on the association between psychological maltreatment and mental health-internalizing and externalizing-problems in adolescents. Participants of the study consisted of 783 adolescents, ranging in age from 14 to 18 years (M = 15.57, SD = 0.88), with 52.9% female and 47.1% male. Several structural equation models were conducted to investigate the mediating role of coping strategies on the effect of psychological maltreatment on adolescents' internalizing and externalizing problems. Findings from mediation analyses demonstrated the mediating effect of active and avoidant coping strategies on the association between psychological maltreatment and mental health problems. The outcomes support adolescents use more avoidant coping strategies and fewer active coping strategies in the face of psychological maltreatment experiences, and this affects their mental health. Taken together, these results should contribute to the design of prevention and intervention services in order to promote mental health. (C) 2017 Elsevier Ltd. All rights reserved.
