Attribution of causality, based on Rotter's (1966) and Weiner's (1979) models, was investigated in a sport setting. The Wingate Sport Achievement Responsibility Scale (WSARS) was developed in order to examine attribution of causality separately for individual and team athletes after successful and unsuccessful events. The scale included feedback from the coach, audience, and teammates. Additional attributions were added in order to examine sport related properties of attributions. In order to examine the distinction between sport-specific attributions and general locus of control (LOG), 69 team athletes and 38 individual athletes were administered the Rotter I-E LOG Scale and the WSARS (Tenenbaum & Weingarten, 1983). Both Rotter's Scale and the WSARS were found to be reliable and valid scales through the probabilistic Rasch Model. Correlational analysis of both scales showed that attribution of causality in team and individual sports were positively related but produced low correlations, which suggests that sport attribution should be examined separately from general LOG. In addition, successful events should be examined separately from unsuccessful events and a distinction should be made between individual and team athletes.

We compared children with, at-risk for, or without developmental coordination disorder (DCD) on the Test of Gross Motor Development (TGMD-2) and the Movement Assessment Battery for Children (MABC) through (a) correlations, (b) gender and age comparisons, (c) cross tab analyses, and (d) factor analyses.
Children (N = 424; age range: 4–10 years) from southern Brazil completed the TGMD-2 and MABC and placed into groups (DCD: ≤ 5th%, n = 58; at-risk: > 5th to ≤ 15th%, n = 133; typically developing (TD) >16th%, n = 233).
The strongest correlation was between total performance on the TGMD-2 and MABC (r = .37). No gender differences were found for performance on the MABC while boys performed better than girls on the TGMD-2. Cross tab analyses indicated a high level of agreement for children who performed in the lowest percentiles on each assessment. Factor analyses suggested that, for both the TD and at-risk groups, three factors loaded on the motor assessments. In contrast, the DCD group loaded on a sport skill, general skill, and a manipulative skill factor, accounting for 42.3% of the variance.
Evidence suggests that children who perform very poorly on one assessment are likely to perform poorly on the other. Children with DCD may have sports-related skill deficiencies.

Sedentary behavior is continuing to emerge as an important target for health promotion. The purpose of this study was to determine the validity of a self-report use of time recall tool, the Multimedia Activity Recall for Children and Adults (MARCA) in estimating time spent sitting/lying, compared with a device-based measure.
Fifty-eight participants (48% female, [mean ± standard deviation] 28 ± 7.4 years of age, 23.9 ± 3.05 kg/m2) wore an activPAL device for 24-h and the following day completed the MARCA. Pearson correlation coefficients (r) were used to analyze convergent validity of the adult MARCA compared with activPAL estimates of total sitting/lying time. Agreement was examined using Bland-Altman plots.
According to activPAL estimates, participants spent 10.4 hr/day [standard deviation (SD) = 2.06] sitting or lying down while awake. The correlation between MARCA and activPAL estimates of total sit/lie time was r = .77 (95% confidence interval = 0.64–0.86; P < .001). Bland-Altman analyses revealed a mean bias of +0.59 hr/day with moderately wide limits of agreement (–2.35 hr to +3.53 hr/day).
This study found a moderate to strong agreement between the adult MARCA and the activPAL, suggesting that the MARCA is an appropriate tool for the measurement of time spent sitting or lying down in an adult population.

The aim of the present study was to examine relations between behavior, intentions, attitudes, subjective norms, perceived behavioral control, self-efficacy, and past behavior across studies using the Theories of Reasoned Action (TRA) and Planned Behavior (TPB) in a physical activity context. Meta-analytic techniques were used to correct the correlations between the TRA/TPB constructs for statistical artifacts across 72 studies, and path analyses were conducted to examine the pattern of relationships among the variables. Results demonstrated that the TRA and TPB both exhibited good fit with the corrected correlation matrices, but the TPB accounted for more variance in physical activity intentions and behavior. In addition, self-efficacy explained unique variance in intention, and the inclusion of past behavior in the model resulted in the attenuation of the intention-behavior, attitude-intention, self-efficacy-intention, and self-efficacy-behavior relationships. There was some evidence that the study relationships were moderated by attitude-intention strength and age, but there was a lack of homogeneity in the moderator groups. It was concluded that the major relationships of the TRA/TPB were supported in this quantitative integration of the physical activity literature, and the inclusion of self-efficacy and past behavior are important additions to the model.

Mental Toughness (MT), which refers to an inner focus and commitment to rise above challenges when facing adversity, is viewed as one of the most important psychological attributes in determining success in sport. However, there is little consensus on key components of MT, and existing measures vary greatly while focusing on elite athletes. The purpose of this research was to develop a measure of MT for use with college athletes. Collegiate and noncollegiate athletes (N = 271) completed the original 54-item Mental Toughness Scale (MTS) in study 1. Factor analysis (PCA) results reduced the scale to an 11-item scale, with good reliability and validity as demonstrated by its positive correlations with self-esteem and flow. A second study of college basketball players (N = 143) was conducted to establish the psychometric properties of the MTS. Study 2 demonstrated convergent, divergent and criterion validity through correlations with related measures, and a CFA provided moderate support for the MTS as a one-dimensional measure of mental toughness in sport.

To be able to draw any conclusions regarding the health effects of occupational physical activity (OPA), more information is needed regarding valid measures to assess OPA. Aims were to compare OPA as assessed with the International Physical Activity Questionnaire long version (IPAQ-L) with OPA assessed with an accelerometer and to assess the contribution of OPA to total PA.
Working adults (n = 441; mean age = 49.4 yrs; 44% males) wore an accelerometer for 7 days in free-living situations and completed the IPAQ-L. Comparisons were made between IPAQ-L-work and accelerometer data limited to working time (Moderate and Vigorous PA (accelerometer-MVPA-work) and average intensity). Subgroup analyses were performed.
Spearman correlation was r = .46 (P < .01) between IPAQ-L-work and accelerometer-MVPA-work. Correlations ranged from r = .27 to r = .55 in respectively obese and overweight subjects. The contribution of IPAQ-L-work to IPAQ-total was 24.7%.
The IPAQ-L work domain is a moderately good measure of time spent on MVPA at work and can be used to assess the contribution of OPA to total PA. This study provides valuable information regarding the use of the IPAQ-L in assessing work domain specific PA, and underscores the importance of assessing OPA, as it can contribute for a substantial part to total PA.

The increasing prevalence of chronic lifestyle diseases in developing countries warrants reliable and valid surveillance of physical activity levels in the population. This study assesses the test-retest repeatability and criterion validity of the WHO-recommended Global Physical Activity Questionnaire (GPAQ) in Vietnamese adults during the dry and wet seasons.
In 2007 a representative sample of 169 adults (25-64 years) was recruited to determine the GPAQ reliability and validity. GPAQ assesses time and intensity of physical activities spent during a usual week. To assess short and long term reliability, participants completed the GPAQ twice during the dry season 2 weeks apart and again 2 months later during the wet season. For validation purposes, participants wore an accelerometer during the 7 days before the first and last GPAQ assessments.
The total GPAQ score showed repeatability correlations of 0.69 after 2 weeks and of 0.55 after 2 months. Total GPAQ score and accelerometer data showed validity correlations of 0.34 and 0.20 in the dry and wet season, respectively. There was a difference in physical activity patterns between the dry and wet seasons.
GPAQ is suitable for surveillance of physical activity among adults in Vietnam.

Neighborhood environment attributes of walkability and access to recreation facilities have been related to physical activity and weight status, but most self-report environment measures are lengthy. The 17-item PANES (Physical Activity Neighborhood Environment Scale) was developed to be comprehensive but brief enough for use in multipurpose surveys. The current study evaluated test-retest and alternate-form reliability of PANES items compared with multi-item subscales from the longer NEWS-A (Neighborhood Environment Walkability Scale—Abbreviated).
Participants were 291 adults recruited from neighborhoods that varied in walkability in 3 US cities. Surveys were completed twice with a 27-day interval.
Test-retest ICCs for PANES items ranged from .52 to .88. Spearman correlations for the PANES single item vs NEWS-A subscale comparisons ranged from .27 to .81 (all P < .01).
PANES items related to land use mix, residential density, pedestrian infrastructure, aesthetic qualities, and safety from traffic and crime were supported by correlations with NEWS-A subscales. Access to recreation facilities and street connectivity items were not supported. The brevity of PANES allows items to be included in studies or surveillance systems to expand knowledge about neighborhood environments.

The Test of Gross Motor Development is used to identify children’s level of motor proficiency, specifically to detect motor delays. This study aimed to translate the TGMD-3 items and assess reliability and content and construct validity for the TGMD-3 in Brazil. A cross-cultural translation was used to generate a Brazilian Portuguese version of the TGMD-3. The validation process involved 33 professionals and 597 Brazilian children (ages 3–10) from the five main geographic regions of Brazil. The results confirmed language clarity and pertinence, as well as face validity of the TGMD-3. High intrarater (.60 to .90) and interrater (.85 to .99) reliability was evident, and test-retest temporal stability was confirmed (locomotor .93; ball skills .81). Adequate internal consistency was present for the skills-to-test and subtests correlations (TGMD-3-BR: α .74; locomotor skills: α .63; ball skills: α .76) and performance-criteria-to-test and -subtest correlations (TGMD-3: α .93; locomotor skills: .90; ball skills: .88). Confirmatory factor analysis supported the construct validity of a two-factor model (RMSEA = .04, 90% confidence interval: .03 to .05; CFI = .94; NFI = .91; TLI = .92; GFI = .94; AGFI = .92). The TGMD-3 is a valid and reliable instrument for Brazilian children.

The study evaluated the concurrent and criterion validity of a new, disposable activity monitor designed to provide objective data on physical activity and energy expenditure in clinical populations.
A sample of healthy adults (n = 52) wore the disposable Metria IH1 along with the established Sensewear armband (SWA) monitor for a 1-week period. Concurrent validity was examined by evaluating the statistical equivalence of estimates from the Metria and the SWA. Criterion validity was examined by comparing the relative accuracy of the Metria IH1 and the SWA for assessing walking/running. The absolute validity of the 2 monitors was compared by computing correlations and mean absolute percent error (MAPE) relative to criterion data from a portable metabolic analyzer.
The output from 2 monitors was highly correlated (correlations > 0.90) and the summary measures yielded nearly identical allocations of time spent in physical activity and energy expenditure. The monitors yielded statistically equivalent estimates and had similar absolute validity relative to the criterion measure (12% to 15% error).
The disposable nature of the adhesive Metria IH1 monitor offers promise for clinical evaluation of physical activity behavior in patients. Additional research is needed to test utility for counseling and behavior applications.
