IntroductionGiven the changing nature of today’s workforce, it is becoming increasingly common, and at times even vital, for employees to be well-prepared for navigating complex social situations to fulfill everyday organizational demands. However, while effective interpersonal interactions are clearly required in many occupations, an ongoing deficiency of critical interpersonal knowledge, skills, and abilities (KSAOs) among employees has been widely recognized. The current study seeks to answer a critical call in the literature for better methods of assessing and developing employee interpersonal KSAOs, especially in terms of how to assess employee effectiveness in the application of these KSAOs to socially complex situations. Specifically, the current study develops and provides initial validity evidence for a situational judgment test (SJT) of critical social thinking, the underlying set of processes that put interpersonal KSAOs into practice.MethodThe present study was conducted within the framework of descriptive and correlation based psychometric design. The statistical population included all managers of the Iran Alloy Steel Company in the first half of 2022, of which 196 people (for exploratory factor analysis and reliability) and 210 separate people (for confirmatory factor analysis and convergent validity), who were selected by stratified sampling method. In order to design the situations and answer options of the scale, were used viewpoints of subject matter experts, and to analyze the data, reliability analysis, correlation methods, exploratory factor analysis and confirmatory factor analysis were used.ResultsIn otder to investigate the validity of situational judgment test of critical social thinking several method were used. The exploratory factor analysis with principal components method and varimax rotation, as expected, suggested a structure based on three subscales include "scanning", "appraising/assessing", "interpreting". Confirmatory factor analysis showed the researcher’s hypothesis that the structure is based on three components is confirmed. Also, convergent validity was confirmed by its correlation with the scores of critical social thinking in the assessment center. Evaluation of internal consistency of scale by Cronbach’s alpha method and correlation of each question whit total score, showed that questions of this scale have acceptable internal consistency. Discussionoverally, the study findings showed situational judgment test of critical social thinking is composed of three factors and acceptable validity and reliability. Consequently, it can be applied to measure critical social thinking of employees in complex organizational situations. This research has provided promising fields for studies that measure and develop critical social thinking in the workplace.Keywords: situational judgment test, critical social thinking, factor analysis, assessment center

The aim of this study was to construct and validate a scale for the measurement of various psychological stressors of undergraduate students studying at Ahvaz Payame Nour University (APNU). An elementary scale consisting of 68 items tapping a wide range of psychological stressors was adminstered to 500 subjects randomly selected from APNU students. Factor analysis of the data yielded formation of a 28-item scale entitled Ahvaz Payame Nour Students Stressors Inventory (APN-SSI) comprising two factors. The first factor with 17items was entitled academic stressors while the second factor consisted of 11-items related to non-academic stressors. The internal consistenly (as measured by Cronbach Alpha) and test-retest reliability coefficients of APN-SSI were found to be satisfactory. To examine the validity of APN-SSI, it was administered to 110 Subjects concurrently with two other widely used standardized scales, the results of which indicated that APN-SSI is a highly valid scale to be used in future studies.
