Simulation-based bayesian inference using BUGS

We illustrate the application of BUGS, a Bayesian computer program, with two examples. The algorithm used in the program is a popular Markov chain Monte Carlo procedure called Gibbs sampling. Bayesian analysis based on simulation has been applied to a wide range of complex problems (Gilks, Richardson, & Spiegelhalter, 1996). The availability of a general purpose program like BUGS should facilitate important applications of Bayesian inference in psychological research.     

Client characteristics associated with behavior change for treated and untreated aggressive boys

This study examined the relationship between subject characteristics of aggressive boys and their behavioral changes during a school year. Seventy-six boys in the fourth, fifth, and sixth grades were identified by their teachers as the most disruptive and aggressive in their classes. These boys were assigned to untreated control, anger-coping, anger-coping plus goal-setting treatment, and minimal treatment goal-setting cells. The anger-coping treatment was based on cognitive behavioral procedures. In both anger-coping cells, greater reductions in rates of disruptive/aggressive off-task classroom behavior was predicted by having higher rates of these behaviors initially, and greater reductions in parents' ratings of aggression was predicted by having poor social problem-solving skills initially. Additional predictors of reductions in parents' ratings of aggression in one, but not both, anger-coping cells included having higher rates of somatic symptoms and poorer social acceptance by peers. In contrast to the other cells, those boys in the no-treatment group who demonstrated the greatest spontaneous improvement on these change measures were the ones who initially were the best problem-solvers and who had higher levels of self-esteem. This cognitive-behavioral treatment appeared to have most impact with those boys who were the most in need of intervention.Portions of this paper were presented at the American Psychological Association annual convention, Anaheim, California, August 1983.

Systems of Psychotherapy: A Comparative Study by Donald H. Ford and Hugh B. Urban

Abstract

The group beholds its leader: a looming figure of fantasy, an emerging figure of reality. Psychic patterns that play out in group cohesion, culture, conflicts, and process are rooted in interaction with this combined object. I describe a two-day conference on relational group psychotherapy. An assemblage had beheld “me,” a visitor with gifts of knowledge, initially welcomed with collective expectation. Rivalrous and acquisitive desire (Girard, 2004) set group process in motion, involving scapegoating and open conflict, but also, self discovery and mutual appreciation. Confronted with “me,” the representative, messenger, even embodiment of truth, the group had to deal with feelings, fantasies, and thoughts that were “not nice.” There were moments of fear for the safety and survival of our group, yet I did not comprehend the extent to which envy, in tooth and nail, with devouring hunger tore into every aspect of our mentalities. Under its catabolic force, I was captured and I could not articulate to myself the sense of what it was, until the group shifted and released me from envy’s intersubjective captivity.

In group, whatever is being talked about—whoever is reacting to whom or to what—the group’s focal conflict, predominating basic assumption, developmental level or stage, its regressions and progressions, dyadic interactions, subgroupings, and so forth, I now assume that on one level, it is all about “me.”     

Dreams,Memories, Reflections by C. G. Jung

Abstract

Group interventions have assumed a growing role in primary prevention and supportive care for cancer and HIV disease. Earlier sections of this Special Report examined empirical findings for these interventions and provided recommendations for future research. The current section offers brief recommendations for service providers, policymakers, and stakeholders.

Group services now occupy an increasingly prominent place in primary prevention programs and medical settings. In previous sections of this Special Report (Sherman, Leszcz et al., 2004; Sherman, Mosier et al., 2004a, 2004b) we examined the efficacy of different group interventions at different phases of cancer or HIV disease, considered characteristics of the intervention and the participants that might influence outcomes, and discussed mechanisms of action. Methodological challenges and priorities for future research were highlighted. In this, the final section, we offer brief recommendations for service providers, policymakers, and other stakeholders. We consider some of the barriers that constrain use of empirically-based group interventions and note how these programs might be implemented more widely and effectively.     

A National Evaluation of Community-Based Youth Cessation Programs: End of Program and Twelve-Month Outcomes

Most youth cessation treatment research consists of efficacy studies in which treatments are evaluated under optimal conditions of delivery. Less is known about the effectiveness of youth cessation treatments delivered in real-world, community based settings. A national sample of 41 community-based youth cessation programs participated in a longitudinal evaluation to identify site, program, and participant characteristics associated with successful cessation. Validated quit rates were comparable to those in randomized controlled trials; 7-day abstinence at the end of program averaged 14% and 30-day abstinence at 12 months averaged 12%. Multivariate GEE models explored predictors of smoking cessation at the end of the programs and at 12 months. Results showed correlates of both short- and long-term cessation. Findings point to the importance of both individual and community-level variables, including motivation, opportunities for and encouragement to engage in activities outside of academics, having youth participate in treatment before they become highly dependent smokers, and community norms and ordinances that discourage youth purchase, use and possession of tobacco. Providing evidence-based treatment to youth in community-based settings results in successful cessation.     

A Retrospective Examination of Child Protection Involvement Among Young Adults Accessing Homelessness Services

Childhood maltreatment is associated with a variety of young adult adversities including homelessness. This study used linked administrative records to develop a population‐level, epidemiological characterization of the child protection histories of young adults accessing homelessness services. The records of all 17‐ to 24‐year‐olds receiving homeless services between 2011 and 2014 in San Francisco County, California (n = 2241) were probabilistically linked to statewide child protective service (CPS) records. Findings document that 50.0% of young adults had been reported for maltreatment at least once during childhood, yet the prevalence of past CPS involvement varied across demographic and child welfare characteristics. Homeless female youth were significantly more likely to have a CPS history than male youth (58.1% vs. 41.5%). Nearly twice as many Black clients accessing homelessness services had a CPS history as did White clients (59.8% vs. 31.8%). Roughly half (47.3%) of those with a childhood history of reported maltreatment had been last reported for maltreatment in another California county. Targeting services that address past trauma and instability among homeless young adults may be justified given the prevalence of CPS history in this population.     

Health Locus of Control After Lung Transplantation: Implications for Managing Health

Health locus of control (HLC) beliefs may influence the health behaviors that patients perform on their own behalf. Likewise, the HLC beliefs that clinicians consider desirable may influence how active they encourage patients to be in managing health. It remains unclear how involved lung recipients want to be and how involved transplant clinicians believe they should be. The aims of this study were to describe HLC beliefs and behaviors manifested by recipients and clinicians in the setting of lung transplantation. Mixed-methods were used, including quantitative techniques to measure demographics, clinical characteristics, and HLC using the Multidimensional Health Locus of Control Scale (MHLC), and qualitative techniques to explore how HLC beliefs were manifest in the clinical setting. Nearly all participants manifested behaviors consistent with high internality and externality, highlighting the importance of holding ‘dual health locus of control’ beliefs for optimal health management and lending support for recipients and clinicians to share responsibility for managing post-transplant health.Funded by the Nursing & Social Sciences Council of the International Society of Heart and Lung Transplantation.     

Validity of the Devereux Scales of Mental Disorders with adolescent psychiatric inpatients

Tested the validity of the Devereux Scales of Mental Disorders (DSMD; Naglieri, LeBuffe, & Pfeiffer, 1994) in a sample of 108 adolescent psychiatric inpatients. DSMD scales were compared to parent-report, interview-based, self-report and diagnostic measures. DSMD measures of conduct problems and delinquency were significantly associated with the predicted parent-report, interview-based, and diagnostic measures of conduct disorder and substance abuse and not with any measures of anxiety or depression. DSMD measures of anxiety and depression were related to other parent-report ratings of internalizing symptoms but had more limited convergent and discriminant validity. The DSMD was compared to the Child Behavior Checklist (CBCL; Achenbach, 1991) for diagnostic classification accuracy. The two measures were comparable in classifying oppositional or conduct disorder. The CBCL was superior for classification of major depression. The DSMD was superior for classification of substance abuse.
