Abstract

Abstract Aim and Background: Mind reading as an ability of interfering mental state of others has an essential role in social interactions. The purpose of the present study is designing farsi version of reading the mind from the voice and evaluation of psychometric properties of it. Methods and Materials: In the present correlation study, twenty hundred sixteen students of Shahid Beheshti and Tehran universities performed farsi version of reading mind from voice (FVRMFV) and reading mind from eyes (RMFE) tests. Two different versions and one short version of the tests were prepared based on items difficulty. Exploratory factor analysis, Pearson correlation and independent T- test were used for evaluation of validity and Chronbach test was used for evaluation of reliability. Linear regression was used for evaluation of predictive validity of the tests. Findings: One main factor revealed from exploratory factor analysis. Correlation between all version of FVRMFV and RMFE was significant (P<0.001) Females performed FVRMFV better than males (P< 0.001) and FVRMFV is better predictor of sexuality than RMFE (P< 0.001). Cronbach&#039;s alpha for main, A, B and Short version relatively found 0.816, 0.571, 0.764 and 0.885 Conclusions: FVRMFV is a reliable and valid test for evaluation of mind reading. FVRMFV is a better predictor of sexuality than RMFE.

Abstract

Aim and Background: The reinforcement sensitivity theory (RST) is important and useful in various areas such as personality, emotion and psychopathology. Sensitivity to Punishment and Sensitivity to Reward Questionnaire-Revised and Clarified (SPSRQ-RC) was developed to measure this theory and address the problem of Sensitivity to Punishment and Sensitivity to Reward Questionnaire (SPSRQ). The purpose of this study was to investigate the psychometric properties of the Persian version of SPSRQ-RC. Methods and Materials: This was a descriptive-correlative study. The statistical population was University of Bojnord students that 485 of whom were selected as the research sample using stratified random sampling method. Data were collected using SPSRQ-RC, Behavioral Inhibition System/Behavioral Activation Scales (BIS/BAS Scales), Positive and Negative Affect Schedule (PANAS). The collected data were analyzed through Cronbach’s alpha, Pearson correlation coefficient, test-retest method, exploratory factor analysis and confirmatory factor analysis. Findings: The principal components method by Varimax rotation led to the extraction of two factors; the sensitivity to Punishment (SP) and sensitivity to Reward (SR) for SPSRQ-RC. The two-factor model explained 38.51 percent of the data variance. 10 items of SPSRQ-RC on the first factor (sensitivity to Punishment) and 10 items on the second factor (sensitivity to Reward) have the significant factor load. All items belonging to each of the sensitivity to punishment and sensitivity to reward factors had a high factor load and confirmed the SPSRQ-RC factor structure. The results of the SPSRQ-RC reliability using internal consistency and test re-test showed that this tool is reliable. Also, the results showed that SPSRQ-RC has a convergent and divergent validity. Conclusions: SPSRQ-RC has good psychometric properties in Iranian society and provides a more appropriate assessment for RST.

Abstract

Aim and Background: Sexual aggression and rape is one of the most challenging concepts in the current era; so the aim of this study was to investigate the psychometric properties of The Acceptance of Modern Myths about Sexual Aggression (AMMSA) Scale in the Iranian population. For this purpose, factor structure, validity and reliability of the scale was examined.
Methods and Materials: A sample group of 937 Iranian people living in Iran who were between 20 and 50 years old, were selected by convenience sampling method; Then they completed the scale of The Acceptance of Modern Myths about Sexual Aggression. Confirmatory factor analysis was used to investigate the factor structure of the scale, Pearson correlation coefficient was used to evaluate the validity, and Cronbach's alpha method was used to determine the internal consistency of the components of this scale. Intra-class correlation coefficient was also used to evaluate the reliability of the retest.
Findings: Confirmatory factor analysis showed that the AMMSA scale has an acceptable factor structure. Cronbach's alpha coefficients obtained from all components (above 0.9) also showed that this scale has a good internal consistency and also the correlation coefficients of Ambivalent Sexism Inventory (ASI) and Interpersonal Reactivity Index (IRI) confirmed divergent and convergent validity of the scale, respectively (P<0.001).
Conclusions: The results showed that The Acceptance of Modern Myths about Sexual Aggression (AMMSA) Scale has appropriate validity and reliability in Iranian population.

Abstract

Aim and Background: The present study was conducted with the aim of investigating the psychometric indicators of Burt & Donnellan's antisocial behavior questionnaire in Iranian adolescents.
Methods and Materials: The research method was a descriptive-correlation type. The statistical population included all high school students in Shiraz. A sample of 567 (342 girls and 22 boys) students was selected by multi-stage cluster sampling. The measurement tools were Burt & Donnellan's (STAB) antisocial behavior questionnaires, Aquino and Reed's moral identity, and Flores-Camacho et al.'s (BSVT-11) tendency to revenge. The data was analyzed using SPSS-24 and AMOS-24 software. In order to analyze the data, exploratory factor analysis and principal components method using varimax rotation were used.
Findings: The findings showed this questionnaire consists of three components: physical aggression, social aggression, and breaking the law. In order to measure the three-factor structure, confirmatory factor analysis was used and findings showed the fit indices of the three-factor model of antisocial behaviors have an acceptable fit with the data. Cronbach's alpha coefficients had acceptable values. Finally, in order to examine the divergent and convergent validity, the simultaneous implementation of the questionnaires of moral identity and tendency to revenge was used. The findings showed the current questionnaire has a negative and significant relationship with the moral identity questionnaire and a positive and significant relationship with the tendency to revenge.
Conclusions: As a result, it can be said the current questionnaire has adequate reliability and validity and can evaluate antisocial behavior and its components in Iranian culture and society. Also, this questionnaire can be used in various educational and research situations.
