Background: The study of job satisfaction is currently approached from an integrative perspective, incorporating various classical and contemporary theories. In Peru, the post-pandemic period has brought about new labour needs, which highlight the importance of having reliable and valid measurement instruments to assess job satisfaction. The Generic Job Satisfaction Scale has demonstrated these quality characteristics. Objective: The aim of this study is to evaluate the psychometric characteristics of the Generic Job Satisfaction Scale created by MacDonald and MacIntyre in 1997 and adapted by Salessi and Omar in 2016 for use in a company in Lima. Method: The study employed a quantitative approach with a descriptive, non-experimental, and instrumental design, with a prospective and cross-sectional methodology, and psychometric analysis. The sampling technique employed was non-probabilistic with a total of 300 employees participating in the study. Results: Content validity evidence was obtained through representativeness, and Exploratory Factor Analysis identified a single factor that explained most of the variability (54.57%) of the items with factorial loads between .54 and .94. The model was tested using Confirmatory Factor Analysis, and optimal results were obtained in the re-specified model (CMIN/DF = 2.24; GFI = .98; RMSEA = .64; CFI = .98; TLI / NNFI = .97; SRMR = .03). Reliability indices were high (a = .86; p = .86), identifying evidence of convergent validity with Engagement, with a positive and moderate correlation (p < .01, rho = .498; CR = .88; AVE = .52). Conclusions: Adequate evidence of psychometric properties was found, and general normative data were established for the study sample. [ABSTRACT FROM AUTHOR]

Background: Insomnia can harm daily functioning and is strongly associated with depression and anxiety symptoms, especially in women. El Salvador has no scales with adequate psychometric properties for their measurement. In this context, the Athens Insomnia Scale (AIS) is a viable option to measure this symptomatology, given its short length of time, solid theoretical foundation, and relevance in other countries. Objective: To analyze the psychometric properties of AIS in the Salvadoran population, in its complete (AIS-8) and abbreviated (AIS-5) versions. Method: The study consisted of 1479 Salvadoran adults from the 14 departments of the country (mean age = 33.3 years, SD = 11.7) who were screened through a non-probability sampling design. Evidence of reliability, validity based on internal structure, and convergent validity were examined. Results: Both scales showed adequate internal consistency, validity based on internal structure through a one-factor structure, invariance between sexes, and convergent validity with depression, anxiety, and stress scales. Conclusions: Both versions have adequate psychometric properties. Shared covariances and partial mismatch indexes suggest the need to analyze its cultural adequacy. Despite this, there is sufficient evidence to support its usefulness in evaluating symptoms of non-organic insomnia in the Salvadoran population. [ABSTRACT FROM AUTHOR]

Background: Students' attributions of their grades may affect their academic performance. However, lack of evidence supporting the validity and reliability of the instruments measuring attribution is a major concern. Objective: To analyze the factor structure, convergent validity and reliability of the Academic Attributional Style Questionnaire adapted to Mexican high school students (EAT-A). Method: The sample consisted of 557 Mexico City students of both sexes aged between 15 and 19. Using a confirmatory factor analysis for both success and failure attributions, a 7-factor structure and a 4-factor structure of the EAT-A were tested. The instrument's convergent validity, internal consistency and reliability were examined. Results: Only the 7-factor structure showed adequate fit indices: RMSEA = .046; SRMR = .053; CFI = .961; TLI = .952 and X²/gl = 2.72. In addition, the EAT-A evidenced convergent validity concerning success and reliability motivation. Conclusion: The EAT-A is a quick- and easy-to-administer instrument for measuring students' attributions of their grades in a reliable and valid manner. [ABSTRACT FROM AUTHOR]

Antisocial behavior refers to a set of acts that violate the rules established for the coexistence of society. One of the self-report measures to assess this type of behavior is the normative deviance scale (NDS). Considering that in the Argentine context no studies on the psychometric properties of the scale were found, the present study aimed to analyze the psychometric properties of the scale in a sample of Argentine youths. To this end, a sample of 794 participants aged between 18 and 25 years was collected. A confirmatory factor analysis was performed; the composite reliability was calculated; and the convergent, discriminant and concurrent validity was assessed (using a self-control scale). In addition, the invariance of the factorial structure of the scale was analyzed. The results confirmed the original factorial structure of the scale with no factorial equivalence across the assessed groups regarding the sex. Also, the results showed adequate psychometric properties for most dimensions which make up the instrument. Findings, limitations and further lines of research are discussed. [ABSTRACT FROM AUTHOR]
