This study was designed to investigate effects of an integrated intervention on psychosocial competence after abortion in unmarried adolescent pregnancies. Study Group: Three hundred eighty-five unmarried adolescent pregnancies aged 15 to 24 years (75.1% employed, 24.9% students) were recruited in the study, of which 190 were allocated into the experimental group and the rests as controls. Methods: The Rosenberg Self-esteem Scale (SES), the shortened version of Tyler's Behavioral Attributes of Psychosocial Competence Scale-Condensed Form (BAPC-C) and the Nowicki-Stricland InternalExternal Locus of Control Scale (NSIE-LOC) were applied to measure self-esteem, coping style, and LOC. Questionnaires were simultaneously administered with abortion service and two-months after intervention. The intervention was organized by an interactive and participatory model designed to increase self-awareness and improve ability of coping under stress with a purpose of reducing occurrence of repeat pregnancy and abortion. Results: Our data showed noticeable changes in coping style and LOC in the experimental group, except for self-esteem ability when comparing with the controls. Conclusion: The psychosocial competence was significantly improved after receiving the intervention. Our study indicates that appropriate psychological intervention for unmarried adolescent pregnancies is necessary to rebuild their normal life after the strike.
