  • Armando Pina

    Dr. Pina studies factors responsible for the developmental course of health and illness in children and adolescents by using basic science approaches and developing interventions that test mechanisms implicated in child and family change.

  • Irwin Sandler

    Dr. Sandler is interested in the development and dissemination of evidence based programs for families experiencing major stressful disruptions of divorce and bereavement. He and his colleagues have conducted research on the development of programs for divorced families (New Beginnings Program) and for bereaved families (Family Bereavement Program). Their research has found encouraging evidence that these programs promote healthy child adjustment including lower rates of substance abuse, depression, continuing distressing grief and externalizing problems and that these effects last up to 15 years following family participation in the programs. Most recently he and his colleagues have been actively involved in teaching community providers to deliver these programs with a high level of quality and fidelity. He has collaborated with Family Courts and community agencies in four counties in Arizona to evaluate the effectiveness of the New Beginnings Program when delivered as a community service and offered to all families experiencing a divorce in those counties. He is very interested in research that evaluates the translation of effective prevention programs into effective community-based services that promote the well-being of children experiencing these major family disruptions. His most recent scholarly publications include major reviews of the literature on the long-term effects of parenting promotion programs (Annual Review of Psychology, 2012) and of meta-analyses of the efficacy of prevention programs with children and youth (Annual Review of Clinical Psychology, 2014).

  • Sharlene Wolchik

    Dr. Wolchik’ s research focuses primarily on understanding malleable risk and protective factors for youths who have experienced parental divorce, developing and testing preventive interventions designed to promote positive adaptation after parental divorce, and understanding the mechanisms of action of these programs. She has also collaborated in the design and evaluation of a preventive intervention for parentally-bereaved youths. Randomized controlled trials of these interventions have found not only positive short-term effects but long-term effects that last up to 15 years after program completion on a wide array of outcomes, including mental disorder, substance use and abuse, risky sexual behaviors, academic performance, self-esteem, and work competence. The program for divorced families, the New Beginnings Program (NBP) is included in SAMHA’S National Registry of Evidence-based Programs and Practices and is one of Blueprints for Healthy Youth Development’s model programs. Most recently, she and her colleagues have been actively involved in working with community agencies to establish the NBP as an ongoing service.
