Current issues and new directions in psychology and health: Culture and health psychology. Why health psychologists should care about culture

This paper presents five studies with 2,420 total participants on the development and validation of the Exercise Dependence Scale (EDS), which is conceptualized based on the Diagnostic and Statistical Manual-IV (APA, 1994) criteria for substance dependence, and differentiates among at-risk, nondependent-symptomatic, and nondependent-asymptomatic exercisers. Results of the studies revealed evidence for the a priori hypothesized components, acceptable test-retest and internal consistency reliability, and content and concurrent validity of the EDS. Individuals at-risk for exercise dependence reported more strenuous exercise, perfectionism, and self-efficacy compared to the nondependent groups. The findings provide initial support for the EDS and indicate the need for a multifaceted approach to its conceptualization and measurement.     

Examining Estimates of Effect Using Non-Overlap of All Pairs in Multiple Baseline Studies of Academic Intervention

The inclusion of single-case design (SCD) studies in meta-analytic research is an important consideration in identifying effective evidence-based practices. Various SCD effect sizes have been previously suggested; non-overlap of all pairs (NAP) is a recently introduced effect size. Preliminary field tests investigating the adequacy of NAP are promising, but no analyses have been conducted using only multiple baseline designs (MBDs). This preliminary study investigated typical values of NAP in MBDs, investigated agreement with visual analysis, and suggested cut scores for interpreting a NAP effect size. Typical values of NAP in MBDs were larger compared to a previous meta-analysis of studies using AB, MBD, or ABAB withdrawal designs, and agreement of suggested cut scores and visual analysis was moderate.     

Prospective Examination of Leisure-Time Exercise Behavior During Pregnancy

The negative and positive content of self-talk, the relationship of self-talk to performance, and persistence following positive and negative feedback were investigated across different cultural backgrounds (European Americans n = 54, East Asians n = 26). East Asians had a significantly larger proportion of negative to positive self-talk than European Americans, d = .62. The greater proportion of negative self-talk related to poorer performance for European Americans, but better performance for East Asians, r ² = .13. European Americans’ practice persistence increased after receiving positive versus negative feedback, d = .59. No differences occurred in persistence for East Asians, d = .06. Results suggest sport psychology consultants and coaches should consider an athlete's cultural background when employing cognitive interventions and providing feedback.     

Roth and Pilling's competence framework for clinical supervision: How generalisable is it?

Background: Roth and Pilling's (2009) competence framework for the supervision of psychological therapies was commissioned as a training resource for the UK Government's ‘Improving Access to Psychological Therapies’ (IAPT) programme. Aims: This paper considers the extent to which it reflects current supervisory practice in the UK. Method: Supervisors' opinions of the non‐modality‐specific competences were surveyed using an online survey form and two emailed survey forms. Findings: Regardless of their professional background, participants felt able to identify with the majority of competences surveyed; however, a minority elicited disagreement. Here, findings suggest that those who drew on cognitive and/or behavioural theory, and were members of the British Association for Behavioural and Cognitive Psychotherapies (BABCP) might be more confident in their ownership than others. However, small sample sizes in the email surveys prevent firm conclusions from being drawn. Conclusions: Regardless of the theoretical approach they subscribe to, supervisors should find the framework helpful as a guide to best practice.     

Obtained versus programmed reinforcement practical considerations in the treatment of escape-reinforced aggression

This investigation provides a preliminary examination of the difference between programmed and obtained reinforcement rates and its potential influence during treatment of aggression in a natural setting. Following a functional analysis that suggested that the aggression of a boy with autism was negatively reinforced, intervention was implemented by the boy's mother. Concurrent fixed-ratio (FR) 1 FR 1 schedules of escape were arranged for manding and aggression. When mands failed to compete effectively with aggression, obtained reinforcement ratios were calculated; these indicated that obtained reinforcement varied from the programmed schedule for aggression but not for mands. Increasing the rate of prompts for mands resulted in an increase in mands and a decrease in aggression to near-zero levels.     

Time Perception: Does It Distinguish ADHD and RD Children in a Clinical Sample?

This study used a double-dissociation design to evaluate whether children with ADHD demonstrated specific deficits relative to children with Reading Disorders. Recent theory suggests that ADHD children have deficits in time perception and working memory, whereas RD children have deficits in phonological decoding. The performance of 113 clinic-referred children aged 6-11 was examined using measures of working memory, phonological processing, and time perception. Respondents completed two time production tasks in which they were to judge when 30-s had elapsed, and another in which they were asked to estimate the duration of the Conners' CPT (CCPT). Time Perception and phonological processing variables were submitted to a 2 x 2 ANCOVA (ADHD vs. RD), covarying for age, SES, IQ, and working memory. Children with ADHD were more likely to overestimate the time taken for the CCPT than children without ADHD, but no group differences were found on the 30-s estimation tasks. Children with RD did not display deficits in time estimation, but showed deficits in auditory phonological processing. The lack of interaction effects supported an "etiological subtype" over the "phenocopy" model of ADHD and RD. No group differences were detected using the CCPT. Although our previous studies did not find an order effect for the Conners' CPT in a 1-hr battery, a fatigue effect was evident with a 1.5-hr battery. The implications for Barkley's behavioral inhibition theories (R. Barkley, 1997) are discussed.     

Self-injurious behavior and the efficacy of naltrexone treatment: a quantitative synthesis

People with mental retardation, autism, and related developmental disabilities who self-injure are treated with a wide array of behavioral techniques and psychotropic medications. Despite numerous reports documenting short-term and some long-term changes in self-injury associated with the opiate antagonist naltrexone hydrochloride, no quantitative review of its efficacy has been reported. We conducted a quantitative synthesis of the peer-reviewed published literature from 1983 to 2003 documenting the use of naltrexone for the treatment of self-injurious behavior (SIB). Individual-level results were analyzed given subject and study characteristics. A sample of 27 research articles involving 86 subjects with self-injury was reviewed. Eighty percent of subjects were reported to improve relative to baseline (i.e., SIB reduced) during naltrexone administration and 47% of subjects SIB was reduced by 50% or greater. In studies reporting dose levels in milligrams, males were more likely than females to respond. No significant relations were found between treatment outcomes and autism status or form of self-injury. Results are discussed with respect to future efficacy work related to study outcomes and the pharmacological treatment of self-injury.
