[Promoting psychosocial well-being in adolescence. A controlled study].

INTRODUCTION
In the recent years a large body of literature has focused its attention to the study of the positive aspects of adolescence, in particular quality of life, happiness and social functioning. The school is an ideal setting for promoting learning abilities, educational processes and also optimal human and social development.


AIM
A new school program for the promotion of psychological well-being has been tested and compared to an attention-placebo intervention in a high school setting.


METHODS
Nine classes (227 students) were enrolled in the study and randomized to: a) School Well-Being Therapy intervention (5 classes); b)attention-placebo (4 classes). 1) Symptom Questionnaire (SQ); 2) Psychological Well-Being Scales (PWB); 3) Revised Children's Manifest Anxiety Scale (RCMAS) were administered at pre- and post-intervention, and after six months.


RESULTS
WBT school intervention was associated to an improved Personal Growth (PWB), and to decreased distress (Somatization (SQ), Physical Well-being (SQ), Anxiety (SQ), and RCMAS Physiological Anxiety).


DISCUSSION AND CONCLUSIONS
A school intervention focused on the promotion of positive emotions and psychological well-being has resulted to be effective not only in increasing these dimensions in high school students, but also in decreasing distress, in particular anxiety and somatization.
