The aim of the present study is to investigate the relationship of posttraumatic growth with basic personality traits and locus of control, and the mediator role of coping strategies in these relationships. One hundred and fourteen women with breast cancer undergoing chemotherapy/radiotherapy treatment or come to the hospital for their post-operational follow-up appointments were recruited. Seventy two mediation models were performed for posttraumatic growth and its factors as dependent variables. The independent variables were basic personality traits (extraversion, conscientiousness, agreeableness, neuroticism, openness to experience, and negative valence) and locus of control. The mediators were coping strategies that is problem-focused coping, emotion-focused coping, and seeking social support (indirect coping). The results suggested that problem-focused coping was a significant mediator in PTG—some basic personality traits (extraversion, openness to experience, conscientiousness, agreeableness) and PTG— external locus of control relationships. Moreover, emotion-focused coping was a significant mediator in the relationship of PTG with some personality traits (conscientiousness, agreeableness, and openness to experience) and external locus of control. Seeking social support did also mediate PTG—external locus of control relationship. The implications of the findings, and the strengths and limitations of the study were also discussed in the light of the literature.
