摘要
背景:尽管大量的干预措施被证明在短期内能够减少青少年的危险行为,但其作用随着持续的行为改变包括若干危险行为的出现而变得模糊起来。目的:确定有无后继措施的父母其同时告知父母和孩子(ImPACT)的监视干预是否能进一步减少青少年逃避、物质滥用、性等危险行为,分析接受危险减少干预措施——儿童重点干预措施(FOK)2年后青少年的理解能力是否改变。
Background: Although numerous interventions have been demonstrated to reduce targeted adolescent risk behaviors for brief periods, sustained behavior changes covering multiple risk behaviors have been elusive. Objective: To determine whether a parental monitoring intervention (Informed Parents and Children Together [ImPACT] ) with and without boosters can further reduce adolescent truancy, substance abuse, and sexual risk behaviors and can alter related perceptions 24 months after intervention among youthwho have all received an adolescent risk-reduction intervention, Focus on Kids (FOK) . Design: Randomized, controlled, 3 - celled longitudinal trial. Setting: Thirty-five low-income, urban community sites. Participants: Eight hundred seventeen African American youth aged 13 to 16 at baseline. Intervention: All youth participated in FOK, an 8 - session, theory-based, small group, face-to-face risk-reduction intervention, 496 youth and parents received the 1-session ImPACT intervention (a videotape and discussion), 238 of the ImPACT youth also received four 90 - minute FOK boosters delivered in small groups. Main Outcome Measures: Responses at baseline and 24 months after intervention to a questionnaire assessing risk and protective behaviors and perceptions. Analyses used General Linear Modeling, intraclass correlation coefficient, analysis of covariance, and multiple comparisons with least significant difference test adjustment. Results: After adjusting for the intraclass correlation coefficient, 6 of 16 risk behaviors were significantly reduced (P≤. 05) among youth receiving ImPACT compared with youth who only received FOK (respectively, mean number of days suspended, 0. 65 vs 1. 17; carry a bat as a weapon, 4. 1% vs 9. 6% ; smoked cigarettes, 12. 5% vs 22. 7% ; used marijuana, 18. 3% vs 26. 8% ; used other illicit drugs, 1. 4% vs 5. 6% ; and, asked sexual partner if condom always used, 77. 9% vs 64. 9% ) . Four of the 7 theory-based subscales reflected significant protective changes among youth who received ImPACT. ImPACT did not produce any significant adverse effects on behaviors or perceptions. Conclusion: A parent monitoring intervention can significantly broaden and sustain protection beyond that conferred through an adolescent risk-reduction intervention.
