Abstract
Background: assessment of psychopathy has gained much attention in the past few decades. The four-factor model of psychopathy has proved to be an efficient model for assessment of psychopathy in forensic and non-forensic samples. Several measures have been developed to capture the four-factor model. These four factors are labeled as interpersonal manipulation, criminal tendencies, erratic lifestyle, and callous affect. Research on psychopathy has remained quite limited in Iran. The present study aimed to validate a 20-item measure of psychopathy consistent with the four-factor model of psychopathy. Williams et al. (2007) model and high-loading items were subjected to a Confirmatory Factor Analysis (CFA). Moreover, reliability coefficients and gender differences were evaluated.
Methods: a convenience sample of 260 university students was recruited from Tehran, Iran. For each factor, a battery of 5 high-loading items (c.f., Williams et al., 2007) was prepared and translated into Persian following the standard back-translation technique. Of note, item 13 (I enjoy drinking and doing wild things) was altered a little to be consistent with Iranian culture. The response option was provided in a 5-point Likert-type format. Potential participants were approached and invited to take part in a psychological study about social behavior. Descriptive statistics, factor structure, internal consistency, and gender differences were evaluated.
Results: item 6 (I’ve stolen a motor vehicle) had the lowest mean while item 13 (I enjoy drinking and doing wild things) had the highest. For interpersonal manipulation, criminal tendencies, erratic lifestyle, and callous affect, the alpha coefficients were 0.55, 0.78, 0.70, and 0.52, respectively. Additionally, the full-scale alpha was 0.79. Goodness-of-fit indices suggested an acceptable fit for the hypothesized four-factor structure of the scale (CMIN/DF = 1.80, RMSEA = 0.056, CFI = 0.90, TLI = 0.88, and GFI = 0.91). An evaluation of gender differences indicated that men had higher scores in all four subscales (0.40 < d < 0.66) as well as the total score (d = 0.76).
Conclusion: the present findings supported the factorial validity and internal consistency of the 20-item self-report measure of psychopathy in Iranian university students. Consistent with previous findings, men showed higher psychopathy, as measured by this newly validated measure. This measure could capture the four-factor model of psychopathy. Therefore, this short scale may be used in future psychopathy research in Iran.

Abstract
The present study aimed to develop and examine psychometric properties of the Spiritual/Religious Perfectionism Scale (SRPS) including construct validity, convergent and discriminant validity, internal consistency, and test-retest reliability. Four hundred and sixty nine Iranian men and women (226 men, 243 women) participated in this study as volunteers. All participants were asked to complete the SRPS, Ego Strength Scale (ESS), Mental Health Inventory (MHI-28), and Positive and Negative Affect (PANAS). The results of exploratory factor analysis supported a general factor structure for the SRPS. The convergent and discriminant validity of the SRPS were supported by an expected pattern of correlations between the scale and the measures of ego strength, psychological well-being, psychological distress, and positive and negative affects. All correlation coefficients between the mean scores on the SRPS and scores of the ego strength, psychological well-being, psychological distress, and positive and negative affects were statistically significant. Coefficient alpha estimates of internal reliability were between .79 and .91 for the SRPS. Test-retest reliability of the SRPS was also calculated at the range of statistically significant of .73. It was concluded that the SRPS can be considered as a reliable and valid scale to measure spiritual/religious perfectionism in Iranian samples.

Abstract
Cybercrime is a growing and worrisome problem, particularly when it involves minors. Cyberaggression among adolescents in particular can result in negative legal and psychological consequences for the people involved. Therefore, it is important to have instruments to detect these incidents early and understand the problem to propose effective measures for prevention and treatment. The purpose of this study was to evaluate the psychometric properties of the Cyber-Aggression Questionnaire for Adolescents (CYBA). In this descriptive-survey study, among the girl and boy students of the second grade of high school in Ahvaz in the academic year 2018-19, a sample of 300 students was selected by multi-stage random sampling method (stratified) and answered the questionnaire of the Cyber-Aggression Questionnaire for Adolescents (Álvarez-García et al., 2016). The reliability of the questionnaire was determined by Cronbach's alpha, Spearman-Brown split-half, and Guttman methods, and its validity and factor structure were determined by construct validity and concurrent validity methods. Cronbach's alpha coefficients, Spearman-Brown split-half and Guttman correlation for the whole questionnaire were 0.94, 0.94, and 0.93, respectively. The results of confirmatory factor analysis showed that the model of measuring cyber-aggression for adolescents has good fitness and its 4-factor structure was confirmed (CFI=0.86, GFI=0.85, and RMSEA=0.079). The concurrent validity of this questionnaire was also confirmed by correlating its items with the items of the European Cyberbullying Intervention Project Questionnaire (ECIPQ) and the Bullying in School Scale (BS) (p<0.05). Therefore, the CYBA offers a valid and reliable measure of cyber aggression in adolescents.

Abstract
The aim of this study was to investigate the psychometric properties of the Persian version of the Parenting Dimensions and Behavior Questionnaire. in this descriptive-normative research, the sample consisted of 329 parents with children aged 7 to 12 years at the elementary educational level who were selected by convenience sampling method in Sanandaj and Marivan in the academic year 1400-1401. To collect data, parenting dimensions and behavior questionnaires (PBDQ, 2015) and Alabama Parenting Questionnaire (APQ, 1990) were used. The results of calculating the content validity ratio (CVR) and content validity index (CVI) with scores higher than 0.83 and 0.75 indicated the appropriateness of the content of the questionnaire. The results of the confirmatory factor analysis confirmed the 6 main factors of the questionnaire and the good fit of the model. The results of the convergent and divergent validity showed a significant correlation between the subscales of the Dimensions and Parenting Behavior Questionnaire and the subscales of the Alabama Parenting Questionnaire (p<01; p<05). The internal consistency of the questionnaire was confirmed using Cronbach's alpha coefficient (α=0/87) and McDonald’s omega coefficient (ꞷ= 0/88). Thus, considering the appropriateness of psychometric properties of the Persian version of the questionnaire (29 items), it can be used in research and evaluation studies to explore more accurately parenting behaviors in Iranian parents.

Abstract
This research was conducted to investigate the psychometric characteristics of the Persian version of the Overt and Covert Reassurance Seeking Questionnaire in Iranian women. The current research was practical in terms of the correlation method. The statistical population of this research was all the women of Tehran city in 2024, who selected a sample of 461 people using the available method and completed the questionnaire. Research tools included: Covert and Overt Reassurance Seeking Inventory (CORSI, Radomsky & et al, 2021), Obsessive Beliefs Questionnaire (OBQ, Obsessive Compulsive Cognitions Working Group, 2001), Self-Esteem Questionnaire (RSE) (Rosenberg, 1965), and Depression Anxiety and Stress Scales (DASS, Lovibond & Lovibond, 1995). Research data were analyzed by exploratory and confirmatory factor analysis, Cronbach's alpha, and Pearson's coefficient. The results of the exploratory factor analysis showed that the research instrument has a four-factor structure after removing items 1 and 7, which was confirmed in the subsequent confirmatory factor analysis. This tool has a direct correlation with depression, anxiety, stress, and obsessive beliefs and has an inverse correlation with self-esteem, which shows the divergent and convergent validity of the research tool (p<0/001). Cronbach's alpha was used to determine reliability, and the obtained values were higher than 0.70, which indicated adequate reliability. The Persian version of the Overt and Covert Reassurance Inventory has good psychometric properties and can be used.
