Study Design: Random sampling design was used in this cross-sectional survey. Materials and Methods: The Americanized English language questionnaire was translated to the Malay language and distributed to community-dwelling Malaysian women living in various locations in Selangor. The construct validity was tested using exploratory factor analysis (EFA) followed by confirmatory factor analysis (CFA). The reliability was determined using Cronbach’s α. Results: A total of 111 women completed the Malay language QUID in this pilot study. The Keiser-Meyer-Olkin (KMO) measure of sampling adequacy of 0.675 and Bartlett’s test of sphericity (χ2 = 284.633, df = 15, p = 0.001) indicated that the EFA was possible. The total variance and the scree plot identified two factors above the initial eigenvalue of 1 while a third factor was just below it (0.758). The CFA output showed a recursive model with the solution being not admissible because two unobserved and exogenous variables had negative variance estimates. The following values of absolute fit indices showed an acceptable level of fit: 1) Chi-square test with χ2 = 4.997, df = 5, p = 0.416, indicated a smaller difference between the expected and observed covariance matrices;2) GFI = 0.986, AGFI = 0.939, RMR = 0.021 and CMIN/DF = 1.0 indicated acceptable level of fit;3) The baseline comparison values of NFI = 0.983 and CFI = 1.0 also indicated a good fit to the data;4) RMSEA = 0.000 was considered a perfect fit indicating that the hypothesized model was a good fit to the observed data. Under the hypothesis of “close fit”, the probability of getting a sample RMSEA as large as 0.000 was 0.567. The Cronbach’s α coefficient of 0.823 indicated good reliability. Conclusion: The Malay language QUID is a valid and reliable instrument for diagnosing female urinary incontinence in the Malaysian population.展开更多

The Youth Experiences Scale for Sport (YES-S) [1], is a five-factor measure of positive youth outcomes specifically designed for the sport context. The YES-S is a promising instrument that fills an important niche in PYD research, and MacDonald et al. provided support for many of its psychometric properties. However, the factor structure of the scale is currently based on an exploratory factor analysis and has not yet been subjected to a confirmatory factor analysis (CFA). The present study was designed to confirm the five-factor structure of the YES-S. A sample of 350 youth sport athletes (196 male, 153 female) completed the YES-S. A CFA showed that a modified version of the five-factor YES-S had excellent fit of the model to the data. An analysis of invariance showed no differences in responses in terms of gender. It is concluded that this short-form YES-S offers excellent psychometric properties while retaining the original factor structure of the YES-S. The results offer further support for the validity of the factor structure of the YES-S while providing a shorter version of the scale, which may be appealing for research with younger sport participants.展开更多

A difficulty in CFA is that the constraint must be specified by users in a subjective manner. For dealing with this difficulty, we propose a computational method, in which the best CFA solution is obtained optimally without relying on users’ judgements. The method consists of the procedures at lower (L) and higher (H) levels: at the L level, for a fixed number of zero loadings, it is determined both which loadings are to be zeros and what values are to be given to the remaining nonzero parameters;at the H level, the procedure at the L level is performed over the different numbers of zero loadings, to provide the best solution. In the L level procedure, Kiers’ (1994) simplimax rotation fulfills a key role: the CFA solution under the constraint computationally specified by that rotation is used for initializing the parameters of a new FA procedure called simplimax FA. The task at the H level can be easily performed using information criteria. The usefulness of the proposed method is demonstrated numerically.展开更多
