The primary purpose of this investigation was to determine the internal consistency of the 60+ functional fitness test battery for older adults. A secondary purpose was to determine whether the number of trials recommended in the testing manual was optimal. Subjects were used from an ongoing study of a fitness program for community-dwelling older adults. Internal consistency coefficients for subtests of flexibility, agility, coordination, and strength were excellent. Post hoc analysis across trials indicated significant differences in means between early trials and later trials. Mean scores stabilized after two or three trials, depending on the subtest of interest. Data provided insight into the number of practice trials and amount of warm-up necessary to implement the 60+ functional fitness test battery in field settings.

This research assessed the reliability, presence of a proposed simplex pattern (construct validity), factorial validity, and multisample invariance of the Situational Motivation Scale (SIMS; Guay, Vallerand, & Blanchard, 2000). In Study 1, data were collected from three physical activity samples. After establishing internal consistencies for all scales, bivariate and interfactor correlations were calculated and the results supported a simplex pattern across samples. The SIMS factorial validity across the three samples was tested via confirmatory factor analysis. Based on modification indices and theoretical justification, the SIMS was reduced to a 14-item model and the multisample invariance of this solution was examined. Results supported partial invariance. In Study 2, a total of 1,008 female PE students responded to the SIMS under two experimental conditions. Internal consistency and the assumed simplex pattern was again supported. Finally, the results of multisample CFA were consistent with the proposed post hoc model respecifications suggested in Study 1, supporting partial invariance.

Two studies were conducted to examine the internal consistency and validity of the state anxiety subscale of the State-Trait Anxiety Inventory (SAI) in the context of acute exercise. SAI responses typically found in the exercise literature were replicated. Analysis at the item level revealed divergent response patterns, confounding the total SAI score. During moderate and immediately after vigorous exercise, scores on items referring to cognitive antecedents of anxiety decreased, whereas scores on items assessing perceived activation increased. Indices of internal showed exercise-associated decreases. A principal-components analysis of responses immediately postexercise revealed a multidimensional structure, distinguishing “cognitive” and “activation” items. By failing to discern exercise-induced and anxiety-related increases in activation from anxiety-antecedent appraisals, the SAI exhibits compromised internal consistency and validity in the context of acute exercise.

A common practice for counteracting response acquiescence in psychological measures has been to employ both negatively and positively worded items. However, previous research has highlighted that the reliability of measures can be affected by this practice (Spector, 1992). The purpose of the present study was to examine the effect that the presence of negatively worded items has on the internal reliability of the Group Environment Questionnaire (GEQ). Two samples (N = 276) were utilized, and participants were asked to complete the GEQ (original and revised) on separate occasions. Results demonstrated that the revised questionnaire (containing all positively worded items) had significantly higher Cronbach a values for three of the four dimensions of the GEQ. Implications, alternatives, and future directions are discussed.

Therefore, the purpose of this research was to evaluate the psychometric properties which comprise reliability (internal consistency, test-retest, and composite), validity (convergent and structural), minimal detectable change (MDC 95 ), and partial confirmatory factor analysis

separation index of 1.5 represents an acceptable level of separation, an index of 2.00 represents a good level of separation, and index of 3.00 represents an excellent level of separation ( Boone et al., 2014 ). We found moderately high internal consistency (separation index = 1.77, Cronbach’s α = .76) for
