-rater reliability and test-retest reliability was determined through Intraclass Correlation (ICC; Model 3, single rating) utilizing IBM SPSS (IBM Statistics version 24.0, Armonk, NY). Significance was accepted at the p  < .05 level and considered to have acceptable reliability when ICC > 0.70 ( Baumgartner

This evaluation informs how close detected transitions are to the true locations. • Matthews Correlation

MVPA recall is shown to be reliable and valid for use in research on PA in children and adolescents from different cultures. 21 – 25 These validation studies provide evidence of adequate reliability, with intraclass correlation coefficients for the all group ranging from .44 25 to .82. 24 An

The purpose of this study was to examine whether team cohesion in women's intercollegiate field hockey was specifically a cause for or an effect of successful performance and to examine what the cause-effect relationship is between cohesion and satisfaction and satisfaction and performance. A secondary purpose was to compare results from a cross-lagged panel correlation analysis with partial correlations and path analysis of the data. The high and significant individual correlations from cohesion to performance and performance to cohesion, combined with the failure of the cross-lagged correlation to indicate any causal predominance, suggested a circular relationship between cohesion and performance. Examination of the satisfaction correlations suggested that satisfaction may be a mediating variable in the cohesion-performance circular relationship. Support for this model totally broke down when the results from the partial correlations and path analysis of the data were examined. The only causal flow, and this only in a few select circumstances, was from success to increased cohesiveness and greater satisfaction, and from increased cohesiveness to greater satisfaction.

An accurate physical fitness survey could be useful in research and clinical care.


To estimate the validity and reliability of a Self-Reported Fitness (SRFit) survey; an instrument that estimates muscular fitness, flexibility, cardiovascular endurance, BMI, and body composition (BC) in adults ≥ 40 years of age.


201 participants completed the SF-36 Physical Function Subscale, International Physical Activity Questionnaire (IPAQ), Older Adults’ Desire for Physical Competence Scale (Rejeski), the SRFit survey, and the Rikli and Jones Senior Fitness Test. BC, height and weight were measured. SRFit survey items described BC, BMI, and Senior Fitness Test movements. Correlations between the Senior Fitness Test and the SRFit survey assessed concurrent validity. Cronbach’s Alpha measured internal consistency within each SRFit domain. SRFit domain scores were compared with SF-36, IPAQ, and Rejeski survey scores to assess construct validity. Intraclass correlations evaluated test-retest reliability.


Correlations between SRFit and the Senior Fitness Test domains ranged from 0.35 to 0.79. Cronbach’s Alpha scores were .75 to .85. Correlations between SRFit and other survey scores were –0.23 to 0.72 and in the expected direction. Intraclass correlation coefficients were 0.79 to 0.93. All P-values were 0.001.


Initial evaluation supports the SRFit survey’s validity and reliability.

In the current study we examined the relationships between stress predictors, stress, and burnout in female high school athletic directors (N = 52). Significant negative correlations between stress and hardiness and between stress and number of social support providers were found. Significant positive correlations between stress and time concerns, personnel concerns, and program success (e.g., winning) subscales of the athletic directing issues scale were also found. Subjects high in hardiness and with adequate social support networks, who also reported few athletic directing issues, were likely to report minimal stress. Significant positive correlations also indicated that stress was related to the burnout dimensions of emotional exhaustion, depersonalization, and personal accomplishment. Based on our results we supported and extended Kelley’s (1993; 1994) model of stress and burnout with a population of female athletic directors.
