Strengthening families program (10-14): effects on the family environment.

ABSTRACT

This study examined whether parent-youth dyads participating in the Strengthening Families Program 10-14 (SFP 10-14) would demonstrate greater postprogram family cohesion, communication, involvement, and supervision and if youth would report less alcohol, tobacco, and other drugs involvement in contrast to a comparison group. From 16 randomly selected schools, we recruited 167 parent-youth dyads 86 from intervention and 81 from comparison schools. The intention-to-treat analysis found one significant change in family environment. Considering dose, it was found that among dyads receiving a full dose, all the outcomes were in the expected direction and effect sizes were moderate. Among dyads receiving a partial dose, 10 of 18 outcomes were in the direction opposite that expected. Youth participation in alcohol, tobacco, and other drugs was very low and did not differ postprogram. Although the expected outcomes were not realized, findings descriptive of dosage effects make a valuable contribution to the field. Study of factors that distinguish intervention completers from noncompleters is recommended.
