Clinical trials exploring the use of counseling and psychotherapy to treat alcohol and other drug use problems in school-aged youth were meta-analyzed using a random effects model.
Of 374 possible studies identified, 20 studies were accepted into the analysis comprising 28 samples of participants (n = 2,837). Counseling and psychotherapy interventions for school-aged youth were inconsistently effective in lowering alcohol use at termination and not effective at follow-up.
Effects of counseling and psychotherapy for drug abuse were consistently significant at termination, but follow-up effects yielded inconsistent results.
With the exception of a sample size effect in the single group drug abuse treatment follow-up analysis, all tests of homogeneity (Cochran's Q and I2) indicated no substantial effects of moderating variables.
