Objective: In today's world, the Internet has become a very important and vital part of our lives. One of the harmful effects of excessive use of the Internet in relation to health is cyberchondria. This related to an increase in the level of anxiety or health distress, and in other words, it is a type of anxiety that leads to searching for health-related information online, and this causes an increase in the level of anxiety, worry and unnecessary expenses. The aim of this study was to investigate the Psychometric properties of the short form of Cyberchondria questionnaire. Method: The present study applied in terms of purpose and its method is descriptive and psychometric studies. The statistical population of the present study was students of public and private universities in Isfahan in 1398. For the present study, 566 students (344 females and 223 males) from Isfahan University students selected by stratified random sampling method using virtual self-examination questionnaires (McElroy and Shevlin, 2014) and health anxiety questionnaire. (Salkovskis and Warwick, 2002) responded. Research data analyzed using SPSS 23 and AMOS 22 software. Results: The findings showed that in the virtual Cyberchondria questionnaire measurement model, all factor loads including compulsion (0.714), distress (0.878), excessiveness (0.805), and reassurance (0.921) were significant. (P <0.001). In addition, the CVI coefficient for all items of the Cyberchondria questionnaire was higher than 0.9 and the intra-class correlation coefficient of the questionnaire resulting from its two implementation was equal to 0.971, which is at a safe distance and is higher than the acceptable value. The reliability obtained using Cronbach's alpha and halving coefficient for the whole questionnaire and all four dimensions is higher than 0.7. The findings also showed that there was a positive and significant relationship between Cyberchondria questionnaire and health anxiety (P <0.001) and the correlation coefficient of the two questionnaires was 0.782. Conclusion: Health-related internet use, in the context of health anxiety is best conceptualized as health-related safety behavior maintained through intermittent reinforcement. In general, according to the results of validity and reliability, the virtual autopsy questionnaire can used in psychological research. Also, these results support the psychometric characteristics and validity of the virtual self-diagnosis questionnaire among the non-clinical sample, and it can be said that this questionnaire is approved in the Iranian sample and has psychometric characteristics and practical tools for diagnosis. It can also used in a short period of time due to the short length of the too

Objective: The aim of this study was to prepare the Persian version of the orthorexia nervosa Scale and evaluate its psychometric properties. Method: The sample of the present study consisted of 639 people aged 18 to 65 years living in Tehran who were tested using the available sampling method. The Persian version of the orthorexia nervosa Scale was prepared after the translation-retranslation process and was administered along with the eating attitude test (EAT-26) and Reef psychological well-being questionnaire (REEF-18). The validity of the scale was assessed using construct, convergent and divergent validity was evaluated through Pearson correlation. Moreover, to assess its reliability, Cronbach's alpha calculation method and composite reliability were used. Findings: The results of exploratory factor analysis indicated the existence of three factors: cognitive, emotional and clinical, and the results of confirmatory factor analysis indicated the goodness of fit and eligibility of the obtained model. Significant correlations between the obtained factors with the eating attitude test and Reef psychological well-being questionnaire also confirmed the convergent and divergent validity of the orthorexia nervosa scale. The reliability of the scale was calculated using Cronbach's alpha coefficient and obtained 0.811 for the all scales and ranged 0.69 to 0.735 for specific scales. Moreover, the composite reliability of the scales ranged between 0.78 and 0.82. Conclusion: Conclusions: In general, it can be said that the Persian version of the orthorexia nervosa Scale has a three-factor structure and has the adequate validity and reliability for use in psychological research in the Iranian sample.

Objective: Adopting a balanced diet promotes human health. However, excessive focus on healthy eating can lead to food obsession, which is termed orthorexia nervosa (ON). The aim of this study was to determine the psychometric properties of the Persian version of the Orthorexia Nervosa Scale (ONS). Method: The statistical population of this study consisted of all undergraduate students of the Islamic Azad University, Tehran Science and Research Branch in the academic year 98-99, among whom 322 students (201 females, 121 males) were selected by multistage sampling, and they responded to the Orthorexia Nervosa Scale (ONS), the Eating Attitude Test (EAT-26), the Obsessive-Compulsive Inventory (OCI-R), the Multidimensional Perfectionism Scale (MPS), the Body Image-Acceptance and Action Questionnaire (BI-AAQ), and the NEO Five Factor Inventory (NEO-FFI). The data were analyzed by exploratory factor analysis, confirmatory factor analysis, Cronbach’s alpha and Pearson correlation using SPSS and AMOS. Findings: Results of the exploratory factor analysis showed 2 factors with eigenvalues higher than 1 which explained 41/92% of the total variance. Also, confirmatory factor analysis indicators implied the optimal fitness of two-factor model of this scale. The total reliability of the scale was estimated to be respectively 0.78 and 0.81 using Cronbach’s alpha and split half. Convergent validity and divergent validity were also confirmed by calculating scale correlation through the aforementioned scales (p<0.05). Also, this scale had a positive and significant correlation with neuroticism (p<0.01). Conclusion: The Orthorexia Nervosa Scale has a relatively proper validity and reliability for being used in Iranian samples and can be a suitable tool for researches of this field.

Objective: The study of the Psychometric Properties Inventory that considers the Motivations for Suicide Attempts in all the theories concerned it can be proportional to the type of motivation,confined for evaluation, diagnosis and intervention. The purpose of this research was to measuring psychometric properties of the Inventory of Motivations for Suicide Attempts (IMSA). Method: The sample consisted of 250 suicide attempted persons who were selected by Purposive sampling method. The data was analyzed through exploratory and confirmatory factor analysis.Result: The results of the exploratory factor analysis identified 9 factors, which in total, explained 64.11% of the variance in mental pain. 43 items in 9 factors were validated by confirmatory factor analysis. Cronbach’s alpha was 0.94 for the whole IMSA, 0.83 for Hopelessness, 0.75 for Psychache, 0.76 for Escape, 0.68 for Burdensomeness, 0.68 for Low Belongingness, 0.68 for Fearlessness, 0.72 for Interpersonal Influence, 0.75 for Help-Seeking and 0.73 for Impulsivity.Conclusion: Persian version of Inventory of Motivations for Suicide Attempts (IMSA) has acceptable psychometric properties among Suicide Attempts and can be used as a valid tool for both clinical and research goals when a comprehensive assessment of Motivations for Suicide Attempts is needed.

Objective: mental pain is a psychological experience, including negative self-evaluation; therefore, it should be measured by self-report tools. The aim of the present study was to determine factor structure and psychometric properties of Mental Pain Scale.Method: this was correlational study and its statistic population consisted all students of the University of Razi Kermanshah. The sample included 300 of these students selected via multi-stage random cluster sampling method. The data was analyzed through exploratory and confirmatory factor analysis by SPSS-22 and AMOS-21 software.Result: the results showed a significant positive correlation among components of mental pain, anxiety, depression, and negative cognitive emotional regulation strategies (P≥0.001). Also, a significant positive correlation was found among components of mental pain and self-compassion (P≥0.001). The results of the exploratory factor analysis identified 6 factors, which in total, explained 66.40% of the variance in mental pain. 44 items in 6 factors were validated by confirmatory factor analysis. Cronbach’s alpha was 0.966 for the whole MPS, 0.925 for emptiness, 0.893 for emotional flooding, 0.877 for loss of control, 0.872 for irreversibility, 0.869 for self-estrangement, and 0.617 for freezing.Conclusion: Persian version of Mental Pain Scale has acceptable psychometric properties among academic students and can be used as a valid tool in psychological research.

Objective: The main purpose of the present study was to investigate psychometric properties of the Brief Religious Coping Scale (BRCS, Pargament, Koenig & Perez, 2000) among male and female cancer patients. 155 cancer patients (119 female, 36 male) completed the Brief Religious Coping Scale. Method: The exploratory and confirmatory factor analysis methods and internal consistency coefficients were used to compute the BRCS's factorial validity and reliability, respectively. Results: The results of principal component analysis (PC) with varimax rotation replicated 2-factor structure of positive and negative religious coping strategies for cancer patients. Goodness-of-fit indices of confirmatory factor analysis confirmed the 2 extracted factors. Internal consistency coefficients for positive and negative religious coping strategies were 0/85 and 0/80, respectively. Conclusion: In sum, BRCS appears to be a good instrument that does what it was intended to do: assess religious methods of coping in an efficient, psychometrically sound, and theoretically meaningful manner
