IntroductionA psychologically rich life is other psychologically desirable life which has recently been conceptualized and introduced by experts in the field of well-being. Developing a psychologically rich life questionnaire is necessary to investigate psychologically rich life in Iranian society empirically. The purpose of the present study was to investigate the psychometric properties of the Persian version of the Psychologically rich life Questionnaire (Oishi et al., 2019) in two general population groups and College students. For this purpose, two studies were conducted. The first study was conducted on the general population, and the second was on the student population.MethodIn the first study, 450 people from the general population of Shiraz were selected using the convenience sampling method; And they responded to Psychologically rich life questionnaires (Oishi et al., 2019), depression-short form (Beck et al., 1996) and meaning of life (Steger, 2010). In the second study, 220 students of Shiraz University who were studying in the academic year of 2019-2020; selected by convenience sampling method; and answered Psychologically rich life questionnaires (Oishi et al., 2019), flourishing scale (Diener et al., 2010), the scale of positive and negative feelings (Diener et al., 2010) and life satisfaction questionnaire (Diener et al., 1985). SPSS-16 and AMOS-21 statistical software analyzed data. The content, construct, convergent and divergent validity of the mentioned questionnaire were investigated using the opinions of educational and clinical psychology experts, exploratory factor analysis, confirmatory factor analysis and correlation coefficients of Psychologically rich life components with related variables, respectively. In order to investigate the reliability of the questionnaire, Cronbach's alpha coefficient was used.ResultsExperts confirmed the representativeness of the questionnaire items to measure Psychologically rich life. In the first study, both types of exploratory factor analysis and confirmatory factor analysis were used for construct validity. Exploratory factor analysis showed that the Persian version of the psychological rich life questionnaire consists of three factors under the headings of «new and various experiences», «unusual experiences», and «non-uniformity». Confirmatory factor analysis also confirmed the fit of the three-factor model with the data. Also, in this study, the logical relationship between the components of a psychologically rich life and related variables indicates this questionnaire's convergent and divergent validity. In the second study, confirmatory factor analysis showed that the three-factor model of a psychologically rich life is consistent with the data. In this study, the logical relationship between the components of a psychologically rich life with related variables indicates the convergent and divergent validity of the questionnaire. In both studies, Cronbach's alpha coefficient confirms the reliability of the questionnaire.ConclusionThe research findings show that the questionnaire mentioned has suitable psychometric indicators for measuring the Psychologically rich life of the general and student population; researchers can use it.

IntroductionThe Internet is one of the most influential forms of mass media that created a great revolution at the global level. Today, most people spend their time on the Internet and use the Internet in various fields such as learning, playing, teaching, social communication, and shopping. In this regard, the present study was conducted to investigate the psychometric properties of the online shopping addiction scale in an Iranian sample. MethodThis research was a descriptive-analytical evaluation study. The sample consisted of 500 women (404) and men (96) in Tehran in 2021 who were selected by the available sampling method and completed the online shopping addiction scale, Saving inventory questionnaire, and psychological well-being questionnaire. Psychometric properties of the online shopping addiction scale were analyzed by confirmatory factor analysis, divergent validity, concurrent validity, Pearson correlation, and Cronbach's alpha coefficient in R software version 4.1 at a significance level of 0.05. Two translators fluent in English separately translated the questionnaire into Farsi. The prepared English versions were compared with the original version of the questionnaire, and with the cooperation of the group of translators, the Farsi version of the questionnaire was prepared and given to several people in different age groups. After identifying and solving the ambiguities in the questions, the final version of the questionnaire was prepared.ResultsAccording to the investigations, the average and standard deviation of the age of the research participants were 29.68 and 9.16, respectively. Based on the results obtained, the six-factor structure (Salience, Tolerance, Mood Modification, Withdrawal, Relapse, Conflict) of the online shopping addiction scale was assessed and validated using confirmatory factor analysis (CFI = 0.93, RMSEA = 0.07). To check the construct validity of the scale, we will first check its confirmatory factor analysis. The suitability of the test items for factor analysis was investigated using the correlation index of the score of each item with the corrected total score. In the study of concurrent and divergent criterion validity, the correlation of the online shopping addiction scale with the positive Saving inventory scale was significant. The relationship between online shopping addiction and psychological well-being was also negative and significant. Cronbach's alpha coefficient for the total score of the online shopping addiction scale was 0.93 and for its dimensions was 0.72 to 0.91.DiscussionThe results of the present study were similar to previous studies, showing the good validity of the tool. The findings of the present study showed that the Persian version of the online shopping addiction questionnaire in the Iranian sample has adequate validity and reliability. The existence of a high correlation with the storage behavior questionnaire as well as a high Cronbach's alpha for the subscales is also a confirmation that this questionnaire can be used effectively. Since less attention has been paid to the issue of online shopping addiction inside the country, by conducting extensive studies, we can see the validity of this scale as much as possible inside the country of Iran.

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
