Psychometric Methodologies and Testing

Physical inactivity is a global problem which is related to many chronic health disorders. Physical activity scales which allow cross-cultural comparisons have been developed. The goal was to assess the reliability and validity of a Turkish version of the International Physical Activity Questionnaire (IPAQ). 1,097 uni…

The purpose of this study is to investigate the impact of estimation techniques and sample sizes on model fit indices in structural equation models constructed according to the number of exogenous latent variables under multivariate normality. The performances of fit indices are compared by considering effects of rela…

There exist differences between the use of Exploratory and Confirmatory Factor analysis at scale adaptation or development studies. The order of factor analysis used would cause the discrepancy in the results. Besides, multiple confirmatory factor analysis would fit well on a single data set. In this study, simulated…

OBJECTIVE: Guidelines have been established for cross-cultural adaptation of outcome measures. However, invariance across cultures must also be demonstrated through analysis of Differential Item Functioning (DIF). This is tested in the context of a Turkish adaptation of the Health Assessment Questionnaire (HAQ). METHO…

OBJECTIVE: To adapt the Functional Independence Measure (FIM) for use in Turkey and to assess its validity and reliability. DESIGN: After the translation procedure, reliability was assessed using internal consistency, inter-rater reliability (kappa) and the intraclass correlation coefficient (ICC). Construct validity…

In this study, the number of factors obtained from parallel analysis, a method used for determining the number of factors in exploratory factor analysis, was compared to that of the factors obtained from eigenvalue and scree plot—two traditional methods for determining the number of factors—in terms of consistency. Pa…
