Background and objective: The aim of this study was to investigate the psychometric properties of the Persian version of the Pure Procrastination Scale (PPS) including reliability, validity, measurement invariance among demographic variables and exploratory and confirmatory factor analysis. Method: In this cross-sectional study, 390 college students from the three universities in Tehran were asked to fill out a battery of four self-report measures that included PPS, DERS, DASS-21, and SWLS questionnaires. Results: The EFA result showed three factors on this scale. PPS measures three dimensions of procrastination called decisional procrastination, behavioral procrastination, and timeliness. The results of multi-group confirmatory factor analysis showed cross group invariance of the factor structure, measurement weights, structural covariances and measurement residuals of PPS across demographic variables. The results revealed high internal consistency and high test-retest reliability. There were statistically significant correlations between PPS and its subscales and DASS-21, DERS, and SWLS. Conclusion: Overall, PPS showed good reliability and validity in Iranian population and it could be applied for assessing their procrastination.

Background: Body image shame considerably contributes to the development and persistence of eating and body image disorders. Objectives: The current study was done to determine the psychometric properties of the body image shame scale and introduce a suitable measure for researchers and therapists in the field of psychological health. Methods: In this study, 409 (136 men and 273 females) individuals who referred to cosmetic surgery clinics in Tehran were chosen. The construct validity of the body image shame was assessed using confirmatory factor analysis and divergent and convergent validity. To assess the divergent and convergent validity of the body compassion scale, appearance anxiety inventory, dysmorphic concern questionnaire and Forms of Self-Criticizing/Attacking and Self-Reassuring Scale were used. Internal Consistency and test-retest reliability (4 weeks’ interval) were used to evaluate reliability. LISREL V8.80 and SSPS V20 were used for data analysis. Results: The results of confirmatory factor analysis showed that the two-factor model (internal and external body image shame) fitted the data (RMSEA = 0.07, NFI = 0.94, CFI = 0.92). Body image shame scale had a positive, significant correlation with dysmorphic concern, appearance anxiety, and self-criticism, and a negative, significant correlation with body compassion (P < 0.05). Also, Cronbach’s alpha coefficient, for the whole of scale, internal body image shame, and external body image shame were 0.85, 0.79, and 0.82, respectively. Conclusions: Psychometric properties of the persian version of the body image shame scale were confirmed in this study. Therefore, it can be used as a valid instrument in research and clinical works in populations with concerns about body image.

AbstractThis study applied a bifactor approach to investigate the structures and simultaneously compare the psychometric properties of three popular self-report internet addiction (IA) instruments. A bifactor confirmatory factor analysis was used to address the structures of the three scales, while the bifactor multidimensional item response model was employed to compare the psychometric properties of the three scales. Results of bifactor confirmatory factor analysis (CFA) showed that the bifactor structures were suitable for the three scales. These corresponding bifactor structures were used in the subsequent bifactor multidimensional item response theory (MIRT) analysis. Results of the bifactor MIRT showed that: three instruments of IA performed well as a whole; the Generalised Problematic Internet Use Scale (GPIUS) and Internet Addiction Test (IAT) provided more test information and had less standard error of measurement, which ranged from −3 to −1 standard deviations of theta or IA severity; the Game Addiction Scale (GAS) performed better than the other two scales in that it can provide more test information in the large area of IA severity (from −1 to +3 SDs). These suggest that the GPIUS and IAT may be the best choice for epidemiological IA studies and for measuring those with lower IA severity. Meanwhile, the GAS may be a good choice when we recruit those with various levels of IA severity.

The How I Think Questionnaire (HIT-Q; Barriga et al., 2001) is a self-report measure of self-serving cognitive distortions. This study aimed to analyze the psychometric properties of the validated version HIT-16-Q (Ara & Shah, 2015) scores in large sample adolescents. Results showed good reliability of the total HIT-16-Q scores: alpha .83. Exploratory Factor Analysis (EFA) revealed a single factor. Confirmatory factor analysis (CFA), revealed the better fit for the one-dimensional structural model. Moreover, the HIT-16-Q has good convergent validity.

ABSTRACT Objective To evaluate the psychometric properties of the Jefferson Medical Empathy Scale, Spanish version (JSE-S), its factorial structure, reliability, and the presence of invariance between genders in the behavior of empathy levels among Chilean nursing students. Method Instrumental research design. The JSE-S was applied to 1,320 nursing students. A confirmatory factor analysis was used. An invariance study between genders was carried out. Descriptive statistics were estimated. Between genders, Student’s T distribution was applied alongside a homoscedasticity analysis. The level of significance was α ≤ 0.05. Results The confirmatory factor analysis determined the existence of three dimensions in the matrix. The statistical results of the invariance tests were significant, and allowed comparison between genders. Differences were found between mean empathy values, as well as in some of its dimensions between genders. Conclusion The factor structure of empathy data and its dimensions is in correspondence with the underlying three-dimensional model. There are differences in empathy levels and their dimensions between genders, with the exception of the compassionate care dimension, which was distributed similarly. Women were more empathetic than men.

Introduction: Given the importance of the scale of difficulty in emotion regulation, in measuring the ability to regulate emotion in adolescents and adults, which is widely used in research and clinical settings, the purpose of this study was to investigate the psychometric properties of short form of difficulty in emotion regulation (DERS-16) in group of Iranian adolescents. Methods: The method of  the present study was a survey in which the statistical population consisted of all 16 to 18 years old male secondary school students in Ardabil City in the 2019-2020 academic year (N = 21756). Among which 409 individuals were selected by cluster random sampling and individually responded to the DERS-16 & NEO-FF-R. To analyze the data internal consistency coefficient, divergent validity and exploratory and confirmatory factor analysis were used. Data were analyzed using SPSS version 16  and LISREL 8.8 software. Results: The results of internal coefficient showed that this scale had a good reliability. Fit indices of confirmatory factor analysis also showed appropriate scale validity (CFI = 0.99, RFI = 0.98, NNFI = 0.99, and RMSEA = 0.048). Conclusion: Findings indicate that the Persian version of this scale is a good tool for measuring the difficulty in regulating emotion and can be used to assess the difficulty in regulating emotion in adolescents and adults.

The study aimed to verify the psychometric properties of the 100-item HEXACO-PI-R questionnaire. The sample consisted of 1624 adults aged from 16 to 79 years (M=34.5, SD=13.35) who filled the paper-pen self-report form of the HEXACO-PI-R. The average internal consistency of the six factors was α=.78 (from .72 for Openness to .81 for Honesty-Humility) and α=.60 for facets. The Altruism scale in the Slovak translation did not reach a satisfactory internal consistency (α=.29). Mean values in the Slovak-speaking sample were 3.29, and standard deviations .53 for factor level and .74 at the facet level. Sex differences showed the higher Emotionality (d=.99) and Honesty-Humility (d= .38) in women. Age differences in Honesty-Humility showed a medium effect size. Factors did not inter-correlate, or they correlated weakly, except for r=.34 in the relationship between Agreeableness and Honesty-Humility. The factors were well distinguished from one another. The exploratory factor analysis with Promax rotation confirmed the six-factor model, which explained in total 44% of data variance, with an average loading of .60. Individual one-factor models met most of the goodness of fit criteria in confirmatory factor analysis, but the six-factor model did not meet them. The controversy associated with assessing the internal structure of multidimensional personality inventories by confirmatory factor analysis is discussed. According to the currently published research studies, the research findings supported the reliability and internal validity of HEXACO-PI-R in Slovak translation.

The aim of this study was to determine the psychometric properties of the Persian version of pregnancy symptoms inventory. A methodological study. This study was conducted on 220 pregnant women. Construct validity was measured by exploratory factor analysis and confirmatory factor analysis. Reliability was measured by intra-class correlation coefficient and internal consistency. Since the items 12 (snoring) and 16 (thrush) failed to obtain the minimum principal axis factoring in exploratory factor analysis, they were removed from the Persian version. Confirmatory factor analysis showed a good fit for the extracted model. Cronbach’s alpha was .94 for the frequency items and .95 for the limitation items. Intra-class correlation coefficient was between .58 and 1 for frequency items and between .73 and 1 for limitation items. The Persian version of pregnancy symptoms inventory was a valid and reliable scale to be used for Iranian pregnant women.

The purpose of the present research was to analyze the psychometric properties of the Trait Meta-Mood Scale (TMMS) in sport context. The TMMS is a 24-item self-report measure that assesses perceived emotional intelligence, which is the extent to which people believe they pay attention to their emotions and are capable of distinguishing and regulating them. Participants were 368 athletes (257 male, 111 female; M age = 21.4 yr., SD = 5.5; range = 14–40). Factor validity was tested via Confirmatory Factor Analysis. Based on factor loadings, covariances, and modification indices, the TMMS was reduced to a 22-item model. This respecification showed adequate reliability and construct validity. Multistep analysis of invariance indicated that the factor structure of the TMMS is invariant across sex. Predictive validity was assessed through path analysis. The results support the use of the Spanish version of the TMMS in a sport context.
