Longitudinal effects of an intervention on perfectionism in adolescents.

Perfectionism is a personality disposition characterized by a person´s striving for flawlessness and the setting of excessively high performance standards. This trait has been associated with a broad range of psychopathological conditions. Consequently, prevention of its harmful effects must start early. OBJECTIVE To investigate if one group session to manage perfectionism has the effect of reducing the levels of this trait, two and six months later. METHOD A community-based sample of 978 Portuguese adolescents from three different high schools completed a self-reporting questionnaire including the Child and Adolescent Perfectionism Scale, before and after one skill session. Three groups were formed: the intervention group received a skill session aimed at reducing perfectionism; control group 1 received a skill session aimed at healthy habits, and control group 2 received no intervention. RESULTS At baseline, no significant mean differences were found by gender or by school in Total Perfectionism or its dimensions. After one session to manage Perfectionism, the intervention group showed significant reduction in self-oriented perfectionism (SOP) scores, two months (p = .001) and six months later (p = .02). No significant reductions were observed in the control groups. DISCUSSION Our findings suggest that adolescents are sensitive to short interventions aimed at reducing perfectionism.
