Abstract
Spiritual intelligence encompasses a set of abilities and capacities that use spiritual resources to increase individual well-being and adaptability. Due to differences in how to express the spiritual intelligence of different cultures, this research seeks to explain spiritual intelligence components based on the Iranian culture in order to provide appropriate instrument for measuring those components. To this end, first principles theoretical study of library research conducted on spiritual intelligence and spiritual intelligence components to describe the culture ofIran, the main religious texts of the dominant culture ofIranwere studied and a total of eight components were extracted. The questionnaire including 108 questions was compiled to measure each of these factors on sample 557 people with cluster sampling method. After removal of 11 questions with load factor of less than 0/4, total reliability of final questionnaire (97 questions) was 0/98. In order to provide factorial structure of the questionnaire, the exploratory factor analysis was used and the result of study indicated that four factors explained 48/39 percent of the total variance of the questionnaire. To explain the factors extracted in the analysis of main components which were above the line gradient, named as transcendent consciouness, spiritual experience, tolerance and forgiveness.

Abstract
The aim of the present study was to consider psychometric properties of Sympson's Hope Scale in a sample of Iranian university students. To do so, 457 students of Hamadan universities were selected through proportional stratified sampling method and were asked to complete Snyder's Hope Scale, Oxford Happiness scale, Hardiness Scale, Beck Hopelessness Inventory, Riff 's Psychological Well-being Scale along with Sympson's Hope Scale (changed a little). Cronbach's coefficient Alpha (0/95), split-half (0/84), convergent validity ( Hardiness, 0/36, Happiness, 0/58, Psychological Well-being, 0/43), divergent validity (Hopelessness, -0/18) were significant (p<0/01). Second order confirmatory factor analysis indicated that the five factors had high factor loadings on one latent factor and therefore six factors model was fitted with the data (AGFI=0/91, RMSEA=0/047, NFI=0/98). Results will be present in detail in the following.

Abstract
The "Social Phobia Inventory" (SPIN) is a well-known screening tool in the field of social phobia disorder (social anxiety disorder) that its creators have designed its items in independent three subscales fear, avoidance, and physiological signs and several international studies and also a few internal studies have been done using it. The weakness of existing studies have motivated these authors to investigate this inventory in a nonclinical Iranian sample. Because of this, 475 students of Tehran University were selected using convenience sampling and completed SPIN. In order to analyze data, data were analyzed with Cross Validation method and Exploratory Factor Analysis (EFA), Parallel Analysis and Confirmatory Factor Analysis (CFA). The results of EFA and Parallel Analysis indicated 2 factors structure of SPIN and the results of CFA indicated the fitness of 2 and 5 factors structure with data. In conclusion, the results of this research suggest the regardless of the separation of items related to subscales fear, avoidance and physiological signs, the items related to fear and avoidances of different areas apply together for assessing severity of this disorder; the phenomenon that is according to social anxiety and united relationship of fear and avoidance.

Abstract
Objective:This study examined the psychometric properties of CRAS of Nelson & Carol (2006) in Iranian couples.. Method: The research was a descriptive-survey study.The study population was composed of married couples in Birjand city.In this study, 350 couples (700) were selected among Birjand couples using available sampling method,& CRAS of Carole & Nelson(2006),revised marital conflict questionnaire of Sanaei (2008) & marital adjustment questionnaire of Spinner (1976) were used. To analyze the data, the statistical indices of Pearson correlation, Cronbach's alpha coefficient, and exploratory factor analysis (using spss 23 software),& confirmatory factor analysis (using AMOS 23software) were used.Results: Exploratory factor analysis showed that the 12-item CRAS in Iranian sample has been saturated from two factors (social Love withdrawal and social sabotage) explaining 56 percent of the scale variance. Confirmatory factor analysis also showed that two-factor model of CRAS has good fitness with data (AGFI =0.93, NFI =0.94, RMSEA =0.06). Cronbach's alpha coefficient was obtained 0.85, convergent validity was obtained 0.4, and divergent validity was obtained -0.42 that all of them were significant at P≥0.01.Conclusion: In general, the results showed that CRAS of Carole & Nelson (2006) has good validity & reliability & it can be used to measure the CRA of couples.

Abstract
The aim of this study was to investigate the psychometric properties of Persian language version of the ambivalence over emotional expression questionnaire (AEQ). Translation-back translation was used to prepare the Persian version of AEQ. A convenience sample of 521 students from three universities in Tehran in 2015-2016 was examined. We assessed validity of the questionnaire by construct validity (via exploratory factor analysis and confirmatory factor analysis) and convergent validity. Cronbach alpha, split half reliability, test-retest reliability coefficients were used for assessing reliablity. Exploratory factor analysis of AEQ’s items showed two factors named ambivalence over expression of positive emotions and ambivalence over expression of negative emotions. Confirmatory factor analysis confirmed the factor structure resulted from exploratory factor analysis which was different from the proposed factors in original questionaire. For total questionnaire and two extracted factors, Cronbach alphas were between 0.77 and 0.86, the Spearman–Brown coefficients were between 0.77 and 0.88 and the test- retest reliability coefficients were between 0.72 and 0.79. The results of this study indicated that this questionnaire have appropriate psychometric properties among Iranian Population.

Abstract
Separation anxiety disorder has high prevalence and lead to demolishing effects on quality of life, the aim of the present research was to examine the confirmatory factor analysis of adult separation anxiety disorder questionnaire in Iranian university students. Among three hundred and ten students, 180 males and 130 females were selected by convenient sampling method and responded to adult separation anxiety disorder questionnaire and depression, anxiety and stress scale. The results of the present research showed that factor analysis using principle component method lead to extract 5 factors of ASA-27. Factors included: separation anxiety, worry about significant others, sleep disturbances, talking a lot, worry about hurting significant others. Reliability of the questionnaire via Cronbach's alpha was 0/88 and correlations between scores of test-retest were 0/64 that indicates high reliability. The result of the present research showed that Persian version of adult separation anxiety disorder and its 5 subscales has desirable reliability in university samples and is appropriate tool for screening this disorder.

Abstract
This study was designed in order to evaluate the reliability and validity of Persian version of Self- concept clarity (SCC).The present study is a descriptive- correlation study. 577 students who were selected via available sampling method. After forward and backward translations of the Self- concept clarity, the original version was compared with the Persian version .Similarities and differences were reviewed and corrected. After the scale was prepared, the Cronbach's alpha test was used to determine the validity of the test. To determine the validity of construct validity methods, convergent and divergent validity was used. Data were analyzed using Factor analysis and Pearson’s correlation method. The findings of factor analysis indicated that this scale is uni-factor in the Iranian sample. Confirmatory factor analysis confirmed the factor structure resulted from exploratory factor analysis which was not different from the proposed factors in original questionnaire. Test-retest reliability was 0.85 and internal consistency of the scale was 0.83 by using Cronbach's alpha, Correlation between the two half-tests was 0.67. Also, the correlation with Rogers self- concept scale was -0.62 and correlation with physiological symptoms sub-scale was -0.13.The results show that the persian version of the of self-concept clarity is a reliable and valid scale.

Abstract
The purpose of the present study was to investigate the psychometric properties of the Persian version of the Valuing Questionnaire (VQ) in people who engaged in weight loss or weight loss maintenance. In this descriptive study, 420 men and women were selected through consecutive sampling and respond to the Persian version of the VQ and the Self-compassion Scale (SCS). To assess the validity of the questionnaire, construct validity (exploratory factor analysis and confirmatory factor analysis) and convergent validity was used. The reliability of the questionnaire was assessed via internal consistency. Exploratory factor analysis of VQ’s items revealed two factors named progress and obstruction, but, at the item level, it was different from the original model of the questionnaire. For two extracted factors, Cronbach’s alphas range was 0.73 to 0.85 suggesting satisfying reliability of the Persian version of the VQ. Confirmatory factor analysis supported the original two factor model of the questionnaire, and fit indices indicated a good model fit. The convergent validity of the questionnaire was also adequate. The Persian version of the VQ has adequate reliability and validity in Iranian society and is a good self-report for research and clinical settings.

Abstract
Death anxiety is commonly experienced by individuals with advanced cancer who have a limited life expectancy. The Death and Dying Distress Scale (DADDS) is a validated measure that was created to capture this experience; but no Persian version is available to date. We conducted a cross-sectional study to explore the psychometric properties of a Pearsion version DADDS (DADDS) in patients with advanced cancer.200 patients with advanced cancer were recruited from the Imam Khomeini, Shohada Tajrish and Baqiyatallah hospitals. Measures administered included: DADDS-C, Patient Health Questionnaire (PHQ-9), and General Anxiety Disorder-7(GAD-7). McDonald's Omega, Cronbach's alpha, Confirmatory Factor Analysis were used to test DADDS reliability and validity.The Persian version of DADDS has good reliability (internal consistency between 0.67 and 0.91 and test-retest reliability between 0.73 and 0.89) and appropriate convergent validity through correlation with PHQ-9 and GAD-7 in the range was between (0.47 to 0.51). Also, according to construct validity, SEM showed that the two-factor model is the best fitting model for DADDS in Persian language.The DADDS is a valid measure of death anxiety in Iranian patients with advanced cancer. It may provide useful information in the assessment and treatment of distress in patients near the end of life.
