An exploration of body dissatisfaction and perceptions of Black and White girls enrolled in an intervention for overweight children

Silhouette measures are one approach to assessing body dissatisfaction in children, although little is known about their use among racially diverse, overweight girls seeking weight-loss treatment. This study assessed racial differences in body dissatisfaction and body size perceptions of 58 girls (ages 6–11, 66% Black, 34% White) participating in a randomized trial for pediatric overweight. Body dissatisfaction did not differ between races; 99% of girls reported an ideal figure smaller than their current one. Black girls selected a larger silhouette to represent their ideal body size, and most girls in both racial groups underestimated their actual size. Outcomes strengthen the argument that, despite an overall preference for a larger body size, obesity might mitigate cultural factors that protect Black girls from body dissatisfaction. Additional research is needed to enhance understanding of children's body size perceptions and dissatisfaction to inform assessment and treatment of pediatric obesity and associated disordered eating symptoms.     

Dietary restraint moderates genetic risk for binge eating

Dietary restraint is a prospective risk factor for the development of binge eating and bulimia nervosa. Although many women engage in dietary restraint, relatively few develop binge eating. Dietary restraint may increase susceptibility for binge eating only in individuals who are at genetic risk. Specifically, dietary restraint may be a behavioral exposure factor that activates genetic predispositions for binge eating. We investigated this possibility in 1,678 young adolescent and adult same-sex female twins from the Minnesota Twin Family Study and the Michigan State University Twin Registry. Twin moderation models were used to examine whether levels of dietary restraint moderate genetic and environmental influences on binge eating. Results indicated that genetic and nonshared environmental factors for binge eating increased at higher levels of dietary restraint. These effects were present after controlling for age, body mass index, and genetic and environmental overlap among dietary restraint and binge eating. Results suggest that dietary restraint may be most important for individuals at genetic risk for binge eating and that the combination of these factors could enhance individual differences in risk for binge eating.     

Development of a metabolic equation for the NuStep recumbent stepper in older adults

The purpose of this study was to develop an accurate metabolic equation for estimating steady-state oxygen consumption (VO2) during submaximal NuStep exercise. Adults (N = 40; M age = 64.0 yr., SD = 6.5; M height = 170.1 cm, SD = 9.1; M weight = 85.7 kg, SD = 19.9) performed two randomized testing sessions. Each session consisted of six stages with combinations of four workloads (1, 3, 5, and 7) at 3 cadences (60, 80, and 100 steps/min.). Multiple regression analysis to predict steady-state VO2 from NuStep workload (W), NuStep steps/min., and subject body mass resulted in the following model (R2 = .73): Steady-state VO2 = 3.5 + 0.016 (W* steps/min.) + 0.092 (steps/min.) - 0.053 (weight). The standard error of the estimate and total error for the prediction of steady-state VO2 under all NuStep workload conditions were 2.3 mL/kg/min. and 2.4 mL/kg/ min., respectively. The standard error of the estimate and total error values are similar to those previously reported in the literature regarding the accuracy of metabolic equations for other exercise modalities. These findings support the use of the equation developed to predict steady-state VO2 for NuStep exercise in older adult clientele.     

Dissemination and Implementation of Cognitive Behavioral Therapy for Depression in the Kaiser Permanente Health Care System: Evaluation of Initial Training and Clinical Outcomes

Notwithstanding its empirical status and strong recommendation in clinical practice guidelines, cognitive behavioral therapy (CBT) continues to be delivered infrequently and with low fidelity on the clinical front lines. Recently, organized efforts and policies within the public sector to disseminate and implement CBT and other evidence-based psychotherapies have yielded encouraging results and provided optimism for bridging the research-to-practice-gap. Following from these efforts, the current article examines the initial impact and experience of the implementation of an individualized approach to CBT training and treatment within the Kaiser Permanente health care system. Initial training outcomes, including changes in general and specific competencies, were assessed using divergent assessment methods within the initial cohort of therapists undergoing training. Initial patient outcomes, including changes in depression and anxiety, were assessed among patients receiving treatment from therapists in training. Results revealed training in and implementation of CBT-D was associated with overall large improvements in therapist competencies and in clinically significant improvements in both depression and anxiety among patients. Findings from the initial phase of dissemination and implementation within a large private system provide support for, and extend recent findings related to, the feasibility and effectiveness of training in and implementation of CBT-D in a real-world context.     

Gender Stereotypes of Emotional Reactions: How We Judge an Emotion as Valid

In this paper we report a partial replication of the finding that women face a double-bind with respect to emotional expression (Kelly & Hutson-Comeaux, 2000) and explore the hypothesis that gender-inconsistent emotional reactions are perceived to be more valid indicators of one's underlying emotional experience than gender-consistent emotional reactions. Men and women evaluated the appropriateness and sincerity of women's and men's overreactions to happy and angry events in both interpersonal and achievement contexts. Women's overreactions to happy events were judged as less appropriate and their emotional reactions were perceived as less sincere than were men's, particularly in an interpersonal context. In addition, men's overreactions to angry events in the interpersonal context were judged as less appropriate and less sincere than were women's. Implications of the findings for other types of social judgments are discussed.     

A review of the observational data-collection and reliability procedures reported in The Journal of Applied Behavior Analysis

The research published in the Journal of Applied Behavior Analysis (1968 to 1975) was surveyed for three basic elements: data-collection methods, reliability procedures, and reliability scores. Three-quarters of the studies reported observational data. Most of these studies' observational methods were variations of event recording, trial scoring, interval recording, or time-sample recording. Almost all studies reported assessment of observer reliability, usually total or point-by-point percentage agreement scores. About half the agreement scores were consistently above 90%. Less than one-quarter of the studies reported that reliability was assessed at least once per condition.     

Note on the invariance of response latency in shuttlebox avoidance learning

Rats trained to avoid shock by running in a shuttlebox showed an orderly increase over trials in the probability of avoidance but no corresponding change over trials in the latency of the avoidance response. Both responding in the presence of shock (escapes) and responding prior to shock onset (avoidances) appeared to be stationary in time. Latencies were found to vary with different experimental conditions but in every case to be invariant over trials.     

Establishing psychological services in a community-based,health care setting: A 3-year case study

Health care practitioners are being challenged to reorganize service delivery and psychology providers are emerging as important participants in shaping the development of primary health care practices. The article outlines the 3-year process of a community/academic/health care center partnership to develop a new model for providing interdisciplinary health care services. The authors describe the process of integrating psychological services into an interdisciplinary, primary care community-based health care center, outline specific planning strategies, and identify the roadblocks and barriers encountered.
