Factor structure and measurement invariance of the Basic Psychological Needs Scale in three South African samples: A bifactor exploratory structural equation modelling approach.

Publication Type: Academic Journal

Source(s): Psychological reports [Psychol Rep] 2022 Oct; Vol. 125 (5), pp. 2760-2787. Date of Electronic Publication: 2021 Jun 26.

Abstract: The Basic Psychological Needs Scale (BPNS) is still being used but validation studies that applied confirmatory factor analysis (CFA) revealed that the scale has inadequate psychometric properties. CFA is based upon restrictive statistical assumptions ...

Scale length does matter: Recommendations for measurement invariance testing with categorical factor analysis and item response theory approaches.

Publication Type: Academic Journal

Source(s): Behavior research methods [Behav Res Methods] 2022 Oct; Vol. 54 (5), pp. 2114-2145. Date of Electronic Publication: 2021 Dec 15.

Abstract: In social sciences, the study of group differences concerning latent constructs is ubiquitous. These constructs are generally measured by means of scales composed of ordinal items. In order to compare these constructs across groups, one crucial require...
