Efficacy of a brief school-based program for selective prevention of childhood anxiety.

Anxiety sensitivity (AS) is recognized as an early risk factor for the development of anxiety disorders. This study evaluates whether a brief school-based selective prevention program reduces AS and anxious and depressive symptoms in children and youth. Participants scoring high in AS but without any current psychopathological disorder were selected from a sample of 613 individuals (61% female, 11-17 years old) and randomly assigned to the prevention program (n=47) or to a waiting-list control (WLC) (n=45) group. A normal control (NC) group (n=53) was also included. After treatment, a significant decrease in AS and in anxiety and depressive symptoms were observed in both prevention and WLC groups. Differences between experimental conditions only emerged, partially, at six-month follow-up (FU) with the prevention group (PG) exhibiting significantly lower AS (p<.05), and equalling NCs. Although the magnitude of change in the PG is comparable to that reported in previous studies with longer and more complex prevention programs, a parallel reduction in the WLCs suggests that the observed decrease in the short term could be mostly time-linked. Despite this, our results encourage research into brief preventive interventions at an individual level.
