Formative evaluation of a motivational intervention for increasing physical activity in underserved youth

The present study was designed to develop an innovative motivational intervention (based on Self-Determination Theory and Social Cognitive Theory) to increase physical activity (PA) in underserved adolescents. Sixty-four adolescents (35 females, 29 males; 50% minority; 65% on reduced lunch program; ages 11-13 yr) participated in either an 8-week motivational intervention after-school (n = 32) or a typical after-school program (n = 32). The conceptual framework for the intervention targeted the social environment (perceived autonomy, perceived social support, participation, fun), cognitive mediators (perceived choice, self-efficacy, and relatedness/belongingness), and motivational orientation (intrinsic motivation, commitment, positive self-concept). Formative evaluation data was collected by staff through daily forms throughout the 8-week program and through observational data completed by independent objective observers during 2 weeks of the program. The major themes that were identified addressed theoretical concepts regarding the intervention and logistical issues in delivering the intervention. The data revealed information regarding the importance of the cognitive appropriateness of the PA and motivational activities, the environmental climate for promoting nurturing relationships, developing specific strategies for increasing intrinsic rather than extrinsic reinforcement, and developing methods for preventing social "cliques" and gender conflicts to maintain an appropriate level of support in the social climate. Themes for training staff included focusing on team building, leadership, and nurturing. This formative evaluation is being used to formalize a randomized trial to test the effects of a student-centered motivational intervention on increasing PA in underserved 6th graders.     

Child abduction, parents' distress, and social support

This study examines how parents of family and nonfamily abducted children cope with stress due to the disappearance of their child. The results show that all parents experience distress, regardless of whether it was a family or nonfamily abduction. Associated with parental distress are factors such as prior family stress, age of the child, recovery status of the child, and measures of social support. More specifically, helpful support from friends has been found to decrease parents' levels of distress, whereas unhelpful support from family and attorneys may increase distress. Mothers and fathers responded to event circumstances and social support in significantly different ways. The need for further research is discussed in the study's conclusions.     

Correlates of comorbid PTSD and polysubstance use in sexual assault victims

A diverse sample of community-residing women in a large metropolitan area who had experienced adult sexual assault was surveyed using standardized measures in an NIAAA-funded study (2003-2004). Four groups (N = 503) of victims: (1) post-traumatic stress disorder (PTSD)-only, (2) PTSD and illicit drug use, (3) PTSD and drinking problems, and (4) PTSD and polysubstance use were compared using bivariate analyses. Victims with PTSD/polysubstance use had lower socioeconomic status, more extensive trauma histories, worse current psychological functioning, more problematic post-assault psychosocial experiences, and more sexual revictimization at follow-up than those with PTSD only. Implications for future research are discussed.     

Effect of Pregnancy Intention on Child Well-Being and Development: Combining Retrospective Reports of Attitude and Contraceptive use

Prior research has documented a relationship between unintended pregnancy and negative consequences for infants and children. Much of this research is based on retrospective reports of intention, but this method has been critiqued as subject to biases in recall and reporting. Non-retrospective measures have also been employed, but these are less widely available and tend to be hindered by limited samples. Using the 1988 National Maternal and Infant Health Survey and its 1991 Longitudinal Follow-Up, a composite measure of reported pregnancy intention and birth control use is constructed to attempt to overcome some limitations of the use of retrospective reports of intention. This composite measure is compared to more conventional measures through analyses predicting the effects of pregnancy intention on child health, activity, and development. Across the different constructions of the pregnancy intention measure, children from unintended pregnancies have poorer outcomes. They are more likely to have less than excellent health, undesirable activity levels, and below median scores on a development assessment. The composite measure predicts similarly to the more conventional measures of intention, but provides an additional dimension that helps address some of the concerns about bias in retrospective reporting, while maintaining the benefit of application in existing large and representative samples. Researchers and policy makers need to continue their concern about the effects of unintended pregnancies, and need widely available measures to understand determinants, consequences, and prevention strategies.     

My student body: a high-risk drinking prevention web site for college students

The authors investigated the efficacy of an interactive Web site, MyStudentBody.com: Alcohol (MSB:Alcohol) that offers a brief, tailored intervention to help heavy drinking college students reduce their alcohol use. They conducted a randomized, controlled clinical trial to compare the intervention with an alcohol education Web site at baseline, postintervention, and 3-month follow-up. Students were assessed on various drinking measures and their readiness to change their drinking habits. The intervention was especially effective for women and persistent binge drinkers. Compared with women who used the control Web site, women who used the intervention significantly reduced their peak and total consumption during special occasions and also reported significantly fewer negative consequences related to drinking. In addition, persistent heavy binge drinkers in the experimental group experienced a more rapid decrease in average consumption and peak consumption compared with those in the control group. The authors judged MSB:Alcohol a useful intervention for reaching important subgroups of college binge drinkers.     

Enhancing parent-child interaction during foster care visits: experimental assessment of an intervention

Mothers of young children recently placed in foster care participated in an intervention to enhance parent-child interaction during visits. The mothers all reported substantial loss and trauma histories. Immediately prior to the visits, the mothers were coached on strategies for separating from their children at the visit's end. The mothers displayed more behavioral strategies for supporting their children when the visit was over, but were less engaged with their children during the leave-taking sequence and displayed fewer ways of maintaining the child's involvement in mother-child interaction during leave-taking than those in a comparison group. This article discusses consideration of parents' trauma history in designing interventions to enhance parent-child interaction.
