This study attempted to assess the construct validity of the performance profile technique (Butler, 1989) within elite track and field athletics. Twelve elite (senior international honors) athletes (5 male, 7 female: mean age = 21.2, SD = 1.81) completed their profile on five occasions across winter training and the indoor season. Support for the construct validity of the profile was identified by a reduction in profile areas of perceived need (F (4, 44) = 11.77, p < .05) which was congruent with the observed increase in performance (F (4, 44) = 26.30, p < .05) as athletes progressed from winter training to the peak of the competitive indoor season. Trend analyses also identified that areas of perceived need in profile constructs, which were classified as most important to performance, showed a greater and more rapid reduction across the five occasions compared to the least important constructs. However, the results raise some concern over the usefulness of the profile for detecting subtle but important changes in performance and perceived need.

Therefore, the purpose of this study was to determine intrarater reliability and construct validity of a hip abductor eccentric strength test. We

Psychosocial factors have been related to physical activity (PA) and are used to evaluate mediation in PA interventions.
Brief theory-based psychosocial scales were compiled from existing measures and evaluated. Study 1 assessed factor structure and construct validity with self-reported PA and accelerometry in overweight/obese men (N = 441) and women (N = 401). Study 2 assessed 2-week reliability and internal consistency in 49 college students.
Confirmatory factor analysis indicated good fit in men and women (CFI = .90; RMSEA = .05). Construct validity was supported for change strategies (r = .29–.46), self-efficacy (r = .19–.22) and enjoyment (r = .21–.33) in men and women, and for cons in women (r = –.19 to –.20). PA pros (r = –.02 to .11) and social support (r = –.01 to .12) were not supported for construct validity. Test-retest reliability ICCs ranged from .49–.81. Internal consistency alphas ranged from .55–.90. Reliability was supported for most scales with further testing needed for cons (alphas = .55–.63) and enjoyment (ICC = 49).
Many of the brief scales demonstrated adequate reliability and validity, while some need further development. The use of these scales could advance research and practice in the promotion of PA.

Long and short flow scales are examined from dispositional (n = 652 long; n = 692 short) and state (n = 499 long; n = 865 short) perspectives. The long flow scales constitute a 36-item multidimensional assessment of flow and have previously demonstrated good psychometric properties. The short flow scales constitute new abbreviated versions of the long forms, contain 9 items, and provide a brief measure of flow from a dimensional perspective. In the current study, long and short flow scales are assessed across a large and diverse physical activity sample. With few exceptions, these flow measures demonstrated acceptable model ft, reliability, and distributions; associations with key correlates in parallel and hypothesized ways; and invariance in factor loadings. Together, the scales provide options for assessing flow in different contexts and when different goals or constraints are operating. Researchers wanting to capture an aggregate of the multidimensional framework might find the short scales a pragmatic alternative when constraints prohibit use of the full-length versions.

Nixon’s (1994a; 1994b; 1996a; 1996b) research using a Risk, Pain, and Injury Questionnaire (RPIQ) is perhaps the most systematic in the risk, pain, and injury literature. The RPIQ is intended to measure the acceptance of dominant discourses on risk, pain, and injury among athletes and others. This article presents a face validity critique of the RPIQ and results of a subsequent content validity analysis based on a study of 171 athletes from a West Coast university. Structural equation modeling used to test Nixon’s original 3-factor model (M1) revealed poor model fit. Two alternate models (M2 and M3) tested reformulated subscale constructs and items. Whereas M2 demonstrated poor construct validity, limited support was found for items in M3. Further replications of this research are recommended.

The Physical Self-Description Questionnaire (PSDQ) is a multidimensional physical self-concept instrument with 11 scales: Strength, Body Fat, Activity, Endurance/Fitness, Sports Competence, Coordination, Health, Appearance, Flexibility, Global Physical, and Global Esteem. The purpose of this study is to evaluate the construct validity of PSDQ responses in relation to 23 external criteria, including measures of body composition, physical activity, endurance, strength, and flexibility for 192 (113 boys and 79 girls) high school students. Each external validity criterion was predicted a priori to be most highly correlated with one of the PSDQ scales. In support of the convergent validity of the PSDQ responses, every predicted correlation was statistically significant. In support of the discriminant validity of the PSDQ responses, most predicted correlations were larger than other correlations involving the same criterion. These results support the construct validity of PSDQ responses in relation to external criteria and their potential usefulness in a wide variety of sports and exercise settings.

Adherence to clinic-based rehabilitation might influence outcomes.
To examine the construct validity and interrater agreement of a measure of adherence to clinic-based rehabilitation.
Repeated-measures in both study 1 and study 2.
43 student rehabilitation practitioners in study 1 and 12 patients undergoing rehabilitation after anterior cruciate ligament reconstruction in study 2.
Participants in study 1 rated the adherence of a simulated videotaped patient exhibiting high, moderate, and low adherence. Two certified athletic trainers rated the adherence of patients at 4 consecutive appointments in study 2.
Main Outcome Measure:
The Sport Injury Rehabilitation Adherence Scale.
In study 1, adherence ratings increased in a linear fashion across the 3 levels of adherence, and r WG(J) and rater-agreement-index values ranging from .84 to .95 were obtained. In study 2, the rater-agreement index was .94.
Strong support was found for the construct validity and interrater agreement of the Sport Injury Rehabilitation Adherence Scale.

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.
