本研究的目的是检验家庭危险因素及其与以家庭为中心的预防性干预措施的剂量和有效性之间的联系。参与者是172个家庭与一个11岁的孩子随机分配到强大的非裔美国人家庭计划（SAAF）的干预条件。两个家庭风险因素，家庭中成人与儿童的比例和青年的非常规性，与剂量呈负相关，剂量定义为参加干预会议的次数。反过来，剂量与前测和后测之间7个月内有针对性的育儿行为的变化相关。家庭风险因素对计划剂量和养育行为变化之间联系的影响对于经历更多风险的家庭来说更强。研究结果强调，有必要制定参与战略，在预防性干预措施中招募和留住高风险家庭。
This study was designed to test hypotheses about family risk factors and their links to dosage and efficacy of a family-centered preventive intervention. Participants were 172 families with an 11 year-old child randomly assigned to the intervention condition in the Strong African American Families Program (SAAF). Two family risk factors, ratio of adults to children in the household and youth unconventionality, were negatively related to dosage, defined as number of intervention sessions attended. Dosage, in turn, was associated with changes in targeted parenting behavior across the 7 months between pretest and posttest. The effect of family risk factors on the link between program dosage and changes in parenting behavior was stronger for families experiencing more risks. The results highlight the need for engagement strategies for recruiting and retaining high-risk families in preventive interventions.
