Overweight and obesity is a major public health concern that includes associations with the development of cardiovascular disease (CVD) risk factors during childhood and adolescence as well as premature mortality in adults. Despite the high prevalence of childhood and adolescent obesity as well as adult CVD, individual studies as well as previous systematic reviews examining the relationship between childhood obesity and adult CVD have yielded conflicting results. The purpose of this study was to use the aggregate data meta-analytic approach to address this gap. Studies were included if they met the following criteria: (1) longitudinal and cohort studies (including case-cohort), (2) childhood exposure and adult outcomes collected on the same individual over time, (3) childhood obesity, as defined by the original study authors, (4) English-language articles, (5) studies published up to June, 2015, (6) one or more of the following CVD risk factors [systolic blood pressure (SBP), diastolic blood pressure (DBP), total cholesterol (TC), high-density lipoprotein cholesterol (HDL), low-density lipoprotein cholesterol (LDL), non-high-density lipoprotein cholesterol (non-HDL), and triglycerides (TG)], (7) outcome(s) not self-reported, and (8) exposure measurements (child’s adiposity) assessed by health professionals, trained investigators, or self-reported. Studies were retrieved by searching three electronic databases as well as citation tracking. Fisher’s r to z score was calculated for each study for each outcome. Pooled effect sizes were calculated using random-effects models while risk of bias was assessed using the STROBE instrument. In order to try and identify sources of heterogeneity, random-effects meta-regression was also performed. Of the 4840 citations reviewed, a total of 23 studies were included in the systematic review and 21 in the meta-analysis. The findings suggested that childhood obesity is significantly and positively associated with adult SBP (Zr = 0.11; 95% CI: 0.07, 0.14), DBP (Zr = 0.11; 95% CI: 0.07, 0.14), and TG (Zr =0.08; 95% CI: 0.03, 0.13), and significantly and inversely associated with adult HDL (Zr = −0.06; 95% CI: -0.10, −0.02). For those studies that adjusted for adult body mass index (BMI), associations were reversed, suggesting that adult BMI may be a potential mediator. Nine studies had more than 33% of items that placed them at an increased risk for bias. The results of this study suggest that childhood obesity may be a risk factor for selected adult CVD risk factors. However, a need exists for additional, higher-quality studies that include, but are not limited to, both unadjusted and adjusted measures such as BMI before any definitive conclusions can be reached.

Item content-relevance is an important consideration for researchers when developing scales used to measure psychological constructs. Aiken (1980) proposed a statistic, V, that can be used to summarize item content-relevance ratings obtained from a panel of expert judges. This article proposes the application of the Score confidence interval to Aiken's V statistic to improve the inference of the unknown population value of V. The application of the Score confidence interval to V is described, a numerical example is provided, and a demonstration of the Score confidence interval is presented for ratings obtained in the development of a scale measuring life skills.

A pragmatic research philosophy is introduced that embraces mixed-method approaches to applied research questions. With its origins in the work of Peirce (1984), James (1907), Dewey (1931), and contemporary support from Rorty (1982, 1990,1991), pragmatism emphasizes the practical problems experienced by people, the research questions posited, and the consequences of inquiry. As a way to highlight applications of pragmatism in sport psychology, pragmatism is compared to constructivism and positivism in terms of philosophical underpinnings and methodological applications. The pragmatic researcher is sensitive to the social, historical, and political context from which inquiry begins and considers morality, ethics, and issues of social justice to be important throughout the research process. Pragmatists often use pluralistic methods during multiphase research projects. Exemplar design types are discussed that logically cohere to a pragmatic research philosophy.

The purpose of the study was to identify and describe the four Ws of athletes’ imagery use: where, when, why, and what. Due to the in-depth nature of the questions being asked, a qualitative approach was employed. The participants were 14 elite athletes (7 male and 7 female), representing 7 different sports. A constant comparative method of analysis was conducted by two investigators. A conceptual framework was developed to display the four Ws of imagery use during and outside practice, as well as for pre-competition, competition, and post competition. Results from the present study indicated where and when athletes use imagery, and extended previous findings on why and for what athletes use imagery. It was proposed that a better understanding of the athletes’ images can serve as a guide to future research and from a practical perspective, facilitate the development of more effective imagery interventions.

The purposes of this study were to identify sources of self-confidence in athletes within the sport-confidence framework of Vealey (1986, 1988), develop a reliable and valid measure of sources of sport-confidence, and extend the conceptual framework of sport-confidence to include sources and test predictions within the expanded model. In Phases 1, 2, and 3 of the study, the preliminary conceptual basis for sources of sport-confidence was developed and initial psychometric evidence supported the factor structure, reliability, and validity of the Sources of Sport-Confidence Questionnaire (SSCQ) with 335 college athletes. In Phase 4, a confirmatory factor analysis supported the hypothesized nine-factor structure of the SSCQ using 208 high school basketball players as participants. The theoretical and practical significance of certain sources of confidence in building stable and enduring self-confidence and motivation in sport are discussed based on the study results.

Summary: Exercise behaviour and sleep are both important health indicators that demonstrate significant decreases with age, and remain modifiable well into later life. The current investigation examined both the chronic and acute relationships between exercise behaviour and self‐reported sleep in older adults through a secondary analysis of a clinical trial of a lifestyle intervention. Seventy‐nine community‐dwelling, initially sedentary, older adults (mean age = 63.58 years, SD = 8.66 years) completed daily home‐based assessments of exercise behaviour and sleep using daily diary methodology. Assessments were collected weekly and continued for 18 consecutive weeks. Multilevel models revealed a small positive chronic (between‐person mean‐level) association between exercise and wake time after sleep onset, and a small positive acute (within‐person, day‐to‐day) association between exercise and general sleep quality rating. The within‐person exercise and general sleep quality rating relationship was found to be reciprocal (i.e. sleep quality also predicted subsequent exercise behaviour). As such, it appears exercise and sleep are dynamically related in older adults. Efforts to intervene on either sleep or exercise in late‐life would be wise to take the other into account. Light exposure, temperature regulation and mood may be potential mechanisms of action through which exercise can impact sleep in older adults.
