Economic Hardship, Neighborhood Context, and Parenting: Prospective Effects on Mexican�CAmerican Adolescent��s Mental Health

This study examined family and neighborhood influences relevant to low-income status to determine how they combine to predict the parenting behaviors of Mexican-American mothers and fathers. The study also examined the role of parenting as a mediator of these contextual influences on adolescent internalizing and externalizing symptoms. Study hypotheses were examined in a diverse sample of Mexican-American families in which 750 mothers and 467 fathers reported on their own levels of parental warmth and harsh parenting. Family economic hardship, neighborhood familism values, and neighborhood risk indicators were all uniquely associated with maternal and paternal warmth, and maternal warmth mediated the effects of these contextual influences on adolescent externalizing symptoms in prospective analyses. Parents' subjective perceptions of neighborhood danger interacted with objective indicators of neighborhood disadvantage to influence maternal and paternal warmth. Neighborhood familism values had unique direct effects on adolescent externalizing symptoms in prospective analyses, after accounting for all other context and parenting effects.

A Latent Profile Analysis of Co-occurring Youth Posttraumatic Stress and Conduct Problems Following Community Trauma

Although most research with youth exposed to violent manmade disasters has focused on internalizing problems, recent work suggests conduct problems (CPs) may also manifest in exposed youth. However, the extent to which youth postevent CPs present independently, versus co-present in conjunction with PTSD symptoms, remains unclear. The present study examined PTS and CP symptom profiles among affected Boston-area youth following the 2013 Boston Marathon bombing. This study used latent profile analysis to identify distinct PTS and CP symptom profiles among Boston-area youth ages 4–19 years (N?=?344) affected by the Boston Marathon bombing events. PTS and CPs were measured using the UCLA-PTSD-RI and the SDQ parent reports, respectively. Analyses identified 3 distinct profiles: presentations characterized by (a) low PTS, low CPs, (b) moderate PTS, low CPs, and (c) high PTS, elevated CPs. The profile characterized by the highest PTS was the only profile with elevated CPs; hyperarousal and emotional numbing/avoidance symptoms showed the greatest distinguishing properties among profiles with and without elevated CP. Types of traumatic exposure experienced by youth were differentially associated with profiles. Specifically, direct (but not relational) exposure distinguished youth classified in the profile showing elevated CPs. Findings suggest interventions following violent manmade disasters may do well to incorporate CP modules when working with youth showing the greatest hyperarousal and emotional numbing, and/or who have directly witnessed the most violence.     

Guidelines for the Investigation of Mediating Variables in Business Research

Business theories often specify the mediating mechanisms by which a predictor variable affects an outcome variable. In the last 30 years, investigations of mediating processes have become more widespread with corresponding developments in statistical methods to conduct these tests. The purpose of this article is to provide guidelines for mediation studies by focusing on decisions made prior to the research study that affect the clarity of conclusions from a mediation study, the statistical models for mediation analysis, and methods to improve interpretation of mediation results after the research study. Throughout this article, the importance of a program of experimental and observational research for investigating mediating mechanisms is emphasized.     

Effect of Transcranial Direct Current Stimulation Combined With Virtual Reality Training on Balance in Children With Cerebral Palsy: A Randomized,Controlled, Double-Blind,Clinical Trial

The authors' aim was to investigate the effects of continuous transcranial direct current stimulation (tDCS) combined with virtual reality training on static and functional balance in children with cerebral palsy (CP). Twenty children with CP (6 girls and 14 boys; M age = 7 years 6 months ± 2 years) were randomly allocated to two groups. The experimental group received active tDCS and the control group received sham stimulation during the 10 sessions of virtual reality mobility training protocols. The children were evaluated on 3 occasions (preintervention, postintervention, and 1-month follow-up). Static balance was evaluated using a force plate under 4 conditions: feet on force plate with (a) eyes open and (b) with eyes closed, and feet on foam mat with (c) eyes open and (d) with eyes closed. Functional balance was evaluated using the Pediatric Balance Scale and the Timed Up and Go Test. The analyses demonstrated statistically significant postintervention and follow-up effects favoring the experimental group over the control group with regard to the Pediatric Balance Scale, Timed Up and Go Test, and area of oscillation of the center of pressure when standing on the force plate with eyes open. The present findings suggest that tDCS can potentiate the effects of virtual reality training on static and functional balance among children with CP.     

Community Implementation of MI-Enhanced Behavior Therapy for Adolescent ADHD: Linking Fidelity to Effectiveness

Evidence-based behavior therapy for adolescent ADHD faces implementation challenges in real-world settings. The purpose of this trial was to investigate the relationship between implementation fidelity and outcomes among adolescents receiving services in the active treatment arm (N = 114; Motivational Interviewing [MI]-enhanced parent-teen behavior therapy) of a community-based randomized trial of adolescent ADHD treatment. Participants received therapy from community clinicians (N = 44) at four agencies in a large, ethnically diverse metropolitan setting. Therapists provided self-report of session-by-session adherence to content fidelity checklists and audio recordings of sample sessions that were coded for MI integrity. Parents provided report of ADHD symptoms and family impairment at baseline, posttreatment, and follow-up, while academic records were obtained directly from the local school district. Results indicated that content fidelity significantly waned across the 10 manualized sessions (d = -1.23); these trends were steepest when therapy was delivered outside the office-setting and parent attendance was low. Community therapist self-report of content fidelity predicted significantly greater improvements in academic impairment from baseline to follow-up. MI delivery quality was not associated with improved outcomes; contrary to hypotheses, lower MI relational scores predicted significantly greater improvements in family impairment over time. Findings indicate that community-based outcomes for evidence-based ADHD treatment are enhanced when treatment is implemented with fidelity. Future work should revise community-based implementation strategies for adolescent ADHD treatment to prevent declines in fidelity over time, thereby improving outcomes.
