Fostering participant engagement is a challenging but essential component of effective prevention programs. To better understand which factors influence engagement, this study examines several predictors of couple engagement in Family Foundations (FF), a preventive intervention for first-time parents shown to enhance parent mental health, couple relations, parenting quality, and child adjustment through age 3 years. FF consists of a series of classes delivered through childbirth education departments at local hospitals. Baseline data on socio-demographics, parent mental health, and couple relationship quality were examined as predictors of participants’ level of engagement in FF (n = 89 couples, 178 individuals). Sociodemographic variables such as parent gender, socioeconomic status, and age predicted program engagement to a limited extent. However, findings indicated that marital status was the best predictor of engagement. Discussion focuses on how findings can inform the development of practices that promote engagement, such as the use of targeted outreach efforts for individuals most at risk of disengagement.  相似文献

Measures of head injury, executive functioning, and intelligence were given to a community sample composed of 102 male perpetrators of intimate partner aggression (IPA) and 62 nonaggressive men. A history of head injury and lower mean score on a measure of verbal intelligence were associated with the frequency of male-perpetrated physical IPA as reported by male perpetrators and their female partners. Lower mean scores on a measure of verbal intelligence also predicted frequency of psychological IPA perpetration. Using the perpetrator subtypes outlined by Holtzworth-Munroe et al. (2000), analyses revealed that compared with other groups, the most severely aggressive subtypes (i.e., borderline-dysphoric and generally violent-antisocial) were the most likely to report a history of head injury and to have significantly lower mean scores on a neuropsychological test of verbal intelligence. The possible role of neuropsychological factors in IPA perpetration and implications for prevention and intervention programs are discussed.  相似文献

Unmet needs for mental health care are common among caregivers involved in the child welfare system. Although child welfare caseworkers are well positioned to identify service needs and refer caregivers to treatment, little is known about the types of referral strategies used in practice, or their effectiveness for promoting mental health service use. The current study examined child welfare caseworkers' use of different referral strategies and the extent to which these strategies are associated with caregivers' receipt of mental health services within a national sample of child welfare cases. Analyses of the second cohort of families from the National Survey of Child and Adolescent Well-Being suggest that child welfare workers more often use informational strategies for referring caregivers, including suggesting treatment or providing information about treatment options. However, social referral strategies such as providing caregivers with direct assistance in completing applications and making and attending appointments were associated with a greater likelihood of caregivers receiving mental health services. Findings support evidence from other service contexts that service use is facilitated by caseworkers' direct support for arranging services. Implications for research and for child welfare managers and administrators are discussed.  相似文献

The role of subsequent school contexts in the long-term effects of early childhood interventions has received increasing attention, but has been understudied in the literature. Using data from the Chicago School Readiness Project (CSRP), a cluster-randomized controlled trial conducted in Head Start programs, we investigate whether the intervention had differential effects on academic and behavioral outcomes in kindergarten if children attended high- or low-performing schools subsequent to the preschool intervention year. To address the issue of selection bias, we adopt an innovative method, principal score matching, and control for a set of child, mother, and classroom covariates. We find that exposure to the CSRP intervention in the Head Start year had significant effects on academic and behavioral outcomes in kindergarten for children who subsequently attended high-performing schools, but no significant effects on children attending low-performing schools. Policy implications of the findings are discussed.  相似文献

Abstract Objective: This study aimed to understand the gaps in college students' knowledge regarding sexual health information. Participants: A sample of 242 participants enrolled in an introductory college course participated in this study in the Fall 2009 semester. Methods: Students participated in 1 of 2 brief interventions and wrote a response paper about their experience. The papers were analyzed using conventional content analysis for information that was new to participants by looking for key words that suggested learning took place. Results: The findings indicated that the majority of participants learned new information. Most learning occurred regarding sexually transmitted infections (ie, types, symptoms, prevalence, treatment, testing) and correct condom use. There were also demographic differences regarding reported new information. Conclusions: Findings can be used to develop future sex education programs for college students by providing college educators with an understanding of where students lack knowledge of sexual health.  相似文献
