We examined psychometric properties of a Modified Physical Activity Questionnaire for Children (MPAQ-C). Thirty-two parents (Study 1), 40 students (6–9 years) and one of each student’s parents (Study 2), and 625 parents (Study 3) completed the MPAQ-C. The MPAQ-C (six items) measured children’s physical activity (PA) after school, and during evenings and weekends for 7 days. Test–retest reliability (Study 1) and convergent validity (Study 2) were measured. Factor validity of the MPAQ-C (Study 3) was examined using confirmatory factor analysis. A single-factor model of the MPAQ-C fit the data well (χ2 (9) = 42.78, p < .001; comparative fit index[CFI] = .977; non-normed fit index [NNFI] = .962; root mean square error of approximation [RMSEA] = .079 [90% confidence interval {CI} = .057 to .11]), with good test–retest reliability, composite reliability (.80) and convergent validity. The factor loadings of MPAQ-C were invariant across fathers/mothers (Δχ2 (6) = 3.44, p > .05). The MPAQ-C is a suitable parent proxy for measuring young Chinese children’s PA.  相似文献

The current study presents the development process and initial validation of a measure designed for assessing psychological needs satisfaction in a secondary school physical education context (Psychological Needs Satisfaction Scale in Physical Education, PNSSPE). Junior secondary school (grades 7 to 9) students (N?=?1,258) were invited to participate in three studies. In Study 1, item generation (34 items) and initial content validity of the PNSSPE were achieved. In Study 2, the factorial structure of the PNSSPE was tested using exploratory and confirmatory factor analyses. Internal consistency reliabilities of the subscales were also examined. In Study 3, the reliability and validity of the scores derived from the PNSSPE were further examined in an independent sample. Overall, the PNSSPE demonstrated good content, factorial, discriminant, and nomological validities. It also demonstrated acceptable internal consistency and test–retest reliability. The measurement model was proven invariant across gender and samples. Psychometric evidence from a series of studies suggests that the PNSSPE could be used as a reliable and valid measure to assess Hong Kong secondary school students’ satisfaction of psychological needs in physical education.  相似文献

The aim of the present study was to assess the influence of self-efficacy and past behaviour on young people's physical activity intentions using an augmented version of Ajzen's Theory of Planned Behaviour. We hypothesized that self-efficacy would exhibit discriminant validity with perceived behavioural control and explain unique variance in young people's intentions to participate in physical activity. We also expected that past physical activity behaviour would attenuate the influence of attitude, subjective norms, perceived behavioural control and self-efficacy on intention. The sample comprised 1152 young people aged 13.5 - 0.6 years (mean - s ) who completed inventories assessing their physical activity intentions, attitudes, subjective norms, perceived behavioural control, self-efficacy and past physical activity behaviour. A confirmatory factor analysis demonstrated that the constructs of the Theory of Planned Behaviour achieved discriminant validity. Furthermore, the measures of attitudes, subjective norms, perceived behavioural control and self-efficacy were significantly related to their respective belief-based measures, supporting the concurrent validity of the measures of the Theory of Planned Behaviour. A non-standard structural equation model demonstrated that attitude and self-efficacy were strong predictors of physical activity intention, but perceived behavioural control and subjective norms were not. Self-efficacy attenuated the influence of attitudes and perceived behavioural control on intention. Past behaviour predicted intention directly and indirectly through self-efficacy and attitude. The present findings demonstrate that young people with positive attitudes and high self-efficacy are more likely to form intentions to participate in physical activity. Furthermore, controlling for past physical activity behaviour revealed that the unique effects of self-efficacy and attitudes on young people's physical activity intentions were unaltered.  相似文献

This study aimed to examine aspects of validity and reliability of the Test of Gross Motor Development-2 (TGMD-2) in Filipino children with intellectual disability. Content and construct validity were verified, as well as inter-rater and intra-rater reliability. Two paediatric physiotherapists tested 81 children with intellectual disability (mean age = 9.29 ± 2.71 years) on locomotor and object control skills. Analysis of covariance, confirmatory factor analysis and analysis of variance were used to test validity, while Cronbach’s alpha, intra-class correlation coefficients (ICC) and Bland–Altman plots were used to examine reliability. Age was a significant predictor of locomotor and object control scores (P = 0.004). The data fit the hypothesised two-factor model with fit indices as follows: χ2 = 33.525, DF = 34, P = 0.491, χ2/DF = 0.986. As hypothesised, gender was a significant predictor for object control skills (P = 0.038). Participants’ mean scores were significantly below mastery (locomotor, P < 0.001; object control, P < 0.001). Cronbach’s alpha was 0.830 for locomotor and 0.792 for object control components. ICC for locomotor and object control scores ranged from 0.995 to 0.998, suggesting excellent intra-rater and inter-rater reliability, confirmed by Bland–Altman analysis. This study provides evidence of sufficient content and construct validity, internal consistency and rater reliability of TGMD-2 for Filipino children with intellectual disability.  相似文献

The purpose of this study was to develop a valid and reliable tool for use in assessing motor skills in preschool children in field-based settings. The development of the Children's Activity and Movement in Preschool Study Motor Skills Protocol included evidence of its reliability and validity for use in field-based environments as part of large epidemiological studies. Following pilot work, 297 children (3–5 years old) from 22 preschools were tested using the final version of the Children's Activity and Movement in Preschool Study Motor Skills Protocol and the Test of Gross Motor Development (2nd Edition). Reliability of the Children's Activity and Movement in Preschool Study Motor Skills Protocol and interobserver reliability were determined using intraclass correlation procedures (intraclass correlation coefficients; ANOVA). Concurrent validity was assessed using Pearson correlation coefficients to compare the Children's Activity and Movement in Preschool Study Motor Skills Protocol to the original Test of Gross Motor Development (2nd Edition). Results indicated that test reliability, interobserver reliability, and validity coefficients were all high, generally above R/r = .90. Significant age differences were found. Outcomes indicate that the Children's Activity and Movement in Preschool Study Motor Skills Protocol is an appropriate tool for assessing motor development of 3-, 4-, and 5-year-old children in field-based settings that are consistent with large-scale trials.  相似文献

This paper describes a revised measure of self-efficacy to overcome barriers to moderate and vigorous physical activity in a sample of 484 high school students in Toronto, Ontario. The students had a mean age of 15.3 years. Principal axis factoring with oblique rotation yielded five factors: self-efficacy to overcome internal, harassment, physical environment, social environment, and responsibilities barriers. Two problematic items were removed, which resulted in a 22-item measure. Subsequent analyses were conducted on responses to this shortened measure. Confirmatory factor analysis supported the five-factor model and demonstrated age- and sexinvariance. The subscales had good internal consistency reliability. Structural regressions demonstrated a strong relationship between the resulting factors and a physical activity measure (energy expenditure), showing predictive validity.  相似文献

Active commuting among school children is being encouraged for physical and environmental reasons, but little is known about its influence on affect. The aim of this study was to test the hypothesis that children who walk further to school experience increased arousal and affective valence compared with children who walk a short distance. This was assessed with the children's feeling scale (CFS) and children's felt arousal scale (CFAS). Distance walked to school and affective change between home and school were assessed over a 2-week period in 99 children between 5 and 10 years of age. Home to school differences in CFS and CFAS scores were compared in children who walked a short (100–300 m); medium (301–500 m), and long distance (over 500 m). Although differences were not always statistically significant, there was evidence that the children who walked further reported a greater increase in their CFAS scores between home and school (average η2 = .08, range: .01–.15) and, to a lesser extent, in their CFS scores (η2 = .04, range: .002–.06). Further research is needed to explore whether there is an optimum walking distance and the contribution of other factors, especially social contacts during commuting, the environment, and the weather.  相似文献

The purpose of this study was to apply the hierarchical linear model (HLM) to assess children's changes in swimming skills. A total of 20 children from a preschool swimming program, 10 boys and 10 girls, were tested by a swimming testing battery at the beginning and at the 4th, 9th, 12th, and 16th months of the program. The swimming-skill scores were analyzed using the HLM at two levels. At Level 1, children's skill levels were defined as a function of a linear growth curve. At Level 2, mean growth trajectory, individual variation in growth trajectory, and reliability of initial status and growth rates were examined first. Then, to determine the impact of the between-participant variables of gender, entry age, and previous swimming experience, parameters (initial status and growth rates) of modeling at Level 1 were defined as a function of these between-participant variables. Entry age was the only determinant found to significantly affect initial status and change in swimming kicking skill. There were, however, other unidentified factors that also contributed to the change in swimming skills. The HLM provided a useful and flexible means for studying changes in motor skills.  相似文献

This study was designed to test the intra- and inter-rater reliability of the University of North Carolina's Balance Error Scoring System in 9- and 10-year-old children. Additionally, a modified version of the Balance Error Scoring System was tested to determine if it was more sensitive in this population (“raw scores”). Forty-six normally developing fourth-grade students underwent balance testing. Twelve trials measured static and dynamic balance. Four adult raters scored the balance tests to yield Cronbach's alpha scores of reliability. Intra-rater University of North Carolina Balance Error Scoring System α varied from .73 to .94 and .94 to .99 when using the raw scores. The inter-rater University of North Carolina Balance Error Scoring System α of the four raters ranged from .77 to .95 and from .88 to .98 when using the raw scores. The University of North Carolina Balance Error Scoring System shows high reliability when used with fourth-grade elementary school children; however, raw scores may show greater reliability in a population of children.  相似文献

The aim of this study was to develop and validate a shortened version of the Profile of Mood States suitable for use with adolescents. The Profile of Mood States-Adolescents (POMS-A) was administered to 1693 participants from two populations: school children and young athletes. Confirmatory factor analysis supported the factorial validity of a 24-item six-factor model using both independent and multi-sample analyses. Correlations of POMS-A scores with previously validated inventories, which were consistent with theoretical predictions, provided evidence of criterion validity. It is proposed that the POMS-A is a valid instrument for the assessment of mood in adolescents.  相似文献

This series of three studies considers the multidimensionality of exercise self-efficacy by examining the psychometric characteristics of an instrument designed to assess three behavioral subdomains: task, scheduling, and coping. In Study 1, exploratory factor analysis revealed the expected factor structure in a sample of 395 students. Confirmatory factor analysis (CFA) confirmed these results in a second sample of 282 students. In Study 2, the generalizability of the factor structure was confirmed with CFA in a randomly selected sample of 470 community adults, and discriminant validity was supported by theoretically consistent distinctions among exercisers and nonexercisers. In Study 3, change in self-efficacy in conjunction with adoption of novel exercise was examined in a sample of 58 women over 12 weeks. Observed changes in the three self-efficacy domains appeared to be relatively independent. Together, the three studies support a multidimensional conceptualization of exercise self-efficacy that can be assessed and appears to be sensitive to change in exercise behavior.  相似文献

The purpose of this study was to translate Arnold and her colleagues’ (Arnold, Fletcher, & Daniels, 2013) Organizational Stressor Indicator for Sport Performers (OSI-SP) into Chinese and examine its psychometric properties with Taiwanese athletes. In study 1, the psychometric properties of the items and the underlying structure of the translated Chinese OSI-SP were examined. In study 2, we used confirmatory factor analysis to examine the factorial structure and examined measurement invariance across genders. In study 3, we examined concurrent and discriminant validity via correlations among the Chinese OSI-SP, coping self-efficacy, perceived stress, and burnout to provide further evidence of criterion validity. Study 4 examined the test-retest reliability of the Chinese OSI-SP. Across these phases, results showed the 5-factor, 16-item Chinese OSI-SP had adequate factor structure, measurement invariance, criterion validity, and reliabilities. We suggest future studies may use this revised Chinese OSI-SP in Taiwan and other Chinese athletic settings.  相似文献

Purpose: A signature characteristic of positive youth development (PYD) programs is the opportunity to develop life skills, such as social, behavioral, and moral competencies, that can be generalized to domains beyond the immediate activity. Although context-specific instruments are available to assess developmental outcomes, a measure of life skills transfer would enable evaluation of PYD programs in successfully teaching skills that youth report using in other domains. The purpose of our studies was to develop and validate a measure of perceived life skills transfer, based on data collected with The First Tee, a physical activity-based PYD program. Method: In 3 studies, we conducted a series of steps to provide content and construct validity and internal consistency reliability for the Life Skills Transfer Survey (LSTS), a measure of perceived life skills transfer. Results: Study 1 provided content validity for the LSTS that included 8 life skills and 50 items. Study 2 revealed construct validity (structural validity) through a confirmatory factor analysis and convergent validity by correlating scores on the LSTS with scores on an assessment tool that measures a related construct. Study 3 offered additional construct validity by reassessing youth 1 year later and showing that scores during both time periods were invariant in factor pattern, loadings, and variances and covariances. Studies 2 and 3 demonstrated internal consistency reliability of the LSTS.Conclusion: Results from 3 studies provide evidence of content and construct validity and internal consistency reliability for the LSTS, which can be used in evaluation research with youth development programs.  相似文献

The effectiveness of the swimming turn is highly influential to overall performance in competitive swimming. The push-off or wall contact, within the turn phase, is directly involved in determining the speed the swimmer leaves the wall. Therefore, it is paramount to develop reliable methods to measure the wall-contact-time during the turn phase for training and research purposes. The aim of this study was to determine the concurrent validity and reliability of the Pool Pad App to measure wall-contact-time during the freestyle and backstroke tumble turn. The wall-contact-times of nine elite and sub-elite participants were recorded during their regular training sessions. Concurrent validity statistics included the standardised typical error estimate, linear analysis and effect sizes while the intraclass correlating coefficient (ICC) was used for the reliability statistics. The standardised typical error estimate resulted in a moderate Cohen’s d effect size with an R2 value of 0.80 and the ICC between the Pool Pad and 2D video footage was 0.89. Despite these measurement differences, the results from this concurrent validity and reliability analyses demonstrated that the Pool Pad is suitable for measuring wall-contact-time during the freestyle and backstroke tumble turn within a training environment.  相似文献
