BACKGROUND This study tests the validity and the invariance of ERI questionnaire (ERIQ) data from health professionals in six different Latin-American countries. METHODS One thousand two hundred ninety-two (1292) participants who worked in hospitals in Argentina, Chile, Colombia, Mexico, Peru and Venezuela completed the ERI and GHQ questionnaires. Partial correlations were carried out as well...

The revised Movement Imagery Questionnaire (MIQ-R: Hall & Martin, 1997) assesses visual and kinesthetic movement imagery abilities and has become a popular questionnaire in sport and exercise psychology research. The purpose of this study was to examine the psychometric properties of the MIQ-R including internal consistency, stability, factor structure, and gender invariance. There were 325 mal...

BACKGROUND Studies have demonstrated that perceived health-related quality of life (HRQOL) of patients receiving hemodialysis is significantly impaired. Since HRQOL outcome data are often used to compare groups to determine health care effectiveness it is imperative that measures of HRQOL are valid. However, valid HRQOL comparisons between groups can only be made if instrument invariance is dem...

BACKGROUND The transtheoretical model is a framework to explain smoking uptake and cessation in adolescence. Decisional balance is proposed as a driver of stage movement. PURPOSE The purpose of this study was to examine the factor structure and measurement equivalence/invariance (ME/I) of the decisional balance scale. METHODS In this study, we used confirmatory factor analysis followed by m...

The factor structure of the Learning Behaviors Scale (LBS) was examined with a sample of 393 randomly selected Canadian youths in a large western city. An identical four-factor structure was observed for the Canadian sample as was obtained in the standardization sample of U.S. youths and with another American sample. Principal axis exploratory factor analysis with equamax rotations produced fac...

1 The aims of this study were to assess the cross-cultural invariance of athletes’ self-reports of mental 2 toughness, and introduce and illustrate the application of approximate measurement invariance 3 using Bayesian estimation for sport and exercise psychology scholars. Athletes from Australia (n = 4 353, Mage = 19.13, SD = 3.27, males = 161), China (n = 254, Mage = 17.82, SD = 2.28, males =...

The present study extended recent work examining the factor structure underlying the Wisconsin Schizotypy Scales by examining the factor invariance of this structure in Spanish and American nonclinical samples of young adults. A series of confirmatory factor analyses were conducted with 547 Spanish and 2,171 American young adults. Consistent with prior work, the best fitting model in both sampl...

Abstract Background Suicide is a public health concern, with an estimated 1 million individuals dying each year worldwide. Individual psychological pain believed to be contributing motivating factor. Therefore, establishing psychometrically sound tool adequately measure important. The Orbach and Mikulincer Mental Pain Scale (OMMP) has been proposed; however, previous psychometric analysis on th...

BACKGROUND Chronic stress results from an imbalance of personal traits, resources and the demands placed upon an individual by social and occupational situations. This chronic stress can be measured using the Trier Inventory for Chronic Stress (TICS). Aims of the present study are to test the factorial structure of the TICS, report its psychometric properties, and evaluate the influence of gend...

This research examined sex differences in the factorial structure of the Philadelphia Geriatric Center Morale Scale. In particular, we view the covariance structure of the scale items as a function of several parameter matrices. We analyzed the factorial invariance by testing hypotheses involving the equivalence constraints of one or more parameter matrices in the male and female populations. D...
