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 purpose of the present research was to examine the factor structure of Fear of Intimacy Scale (Descutner & Thelen, 1991) and to get an acute tool which measures the degree of the Fear of Intimacy among the Iranian people. Population of the study included some married couples living in Tehran, Iran. A sample of 567 subjects, 329 females (58%) and 238 males (41.9%), completed the relevant questionnaire. Exploratory and confirmatory Factor Analysis was used to analyze the structure of the questionnaire. Factor analysis revealed two factors existed among the 35 items of the questionnaire: fear of intimacy in the relationship with the spouse, fear of intimacy in the relationship with the others. The internal consistency for the whole scale, factor 1 and factor 2 was 0.83 ,0.81 ,0.72 respectively test-retest reliability for the whole scale, factor 1 and factor 2 was 0.92, 0.87,0.85 respectively. Confirmatory factor analysis showed that the data hadsignificant correlation. Negative correlation(-0.58) between this scale and the intimacy scale of walker and Thompson was indicative of the construct validity of test. FIS can be used to help those having problems in increasing the level of intimacy with others especially their spouse. Further, this scale can be used in clinical works and research.

Abstract
The aim of this research was to investigate the Factor Structure and Psychometric Properties of the Persian version of State Adult Attachment Scale (SAAS). Using stratified random sampling method, 321 students (148 male and 173 female students) from Shiraz University were selected. Participants completed Persian version of State Adult Attachment Scale (SAAS), revised version of the adult attachment scale (RAAS), Beck Depression Inventory (BDI–II) and Beck Anxiety Inventory (BAI). The construct validity of the Persian version of State Adult Attachment Scale (SAAS) was assessed via factor analysis and internal correlations. Also, Concurrent validity coefficients of this scale were calculated based on the correlations of this scale with the revised version of the adult attachment scale (RAAS), Beck Depression Inventory (BDI–II) and Beck Anxiety Inventory (BAI) scores. Moreover, using Cronbach’s Alpha the reliability of the Persian version of State Adult Attachment Scale (SAAS) was assessed. Principal component analysis with Varimax-rotation showed the three factors including Secure, anxious and avoidant attachments which were in accordance with factor structure of SAAM in major population. Result of internal correlations and correlations with BAI, BDI-II and RASS, revealed good construct and Convergent validity. Finally, reliability of these subscales were reached between 0/72 - 0/84 according to the Cronbach’s Alpha. According to the results of this study, SAAM can be used for the Iranian population in clinical and research fields as a reliable and valid scale.

Abstract
Mental adjustment to cancer is known a psychological, physical and psychological health variable in cancer patients. The present study examined the factor structure and psychometric properties of the Mini - Mental Adjustment to Cancer Scale (Mini-MA)in a sample of Iranian adults.The sample consisted of 320 cancer patients selected through non-random convenient sampling procedure from the hospitals and clinics in Kermanshah and Shiraz, and was conducted Mini - Mental Adjustment to Cancer Scale, among of them 100 was also completed the Hospital Anxiety and Depression Scale. Statistical methods for analysing the data exploratory, discriminate validity and for internal consistency Cronbach alpha coefficients were used. Alpha coefficients for the subscales helplessness/hopelessness, 0.94, cognitive avoidance 0.76, anxious preoccupation, 0.90, Fatalism, 0.77, the fighting spirit 0.80 and the total scale as well as 0.84, respectively. Factor analysis confirmed that the five factors in the Mini-MAC. Significant correlations between subscales of Mini-MAC and Hospital Anxiety and Depression Scale also show that this scale has discriminate validity. The results confirm the five-factor structure of the Mini-MAC scale and also a reliable and valid scale, shows this scale has power to measure aspects of mental adjustment with cancer.

Abstract
Over the years, weight loss motivation has been introduced as an important factor in weight loss and its stability. The purpose of the present study was to investigate psychometric properties of the Motivation for Weight Loss Questionnaire (WLM-Q) among overweight and obese Individuals. In this study, the Persian version of the WLM-Q prepared using back-translation was administrated to 453 individuals referring to diet therapy centres in Tehran. The internal consistency of the Persian version of the WLM-Q was assessed via Cronbach’s alpha. Moreover, the factor structure of the scale was assessed using confirmatory and exploratory factor analysis. The results of Cronbach's alpha for the whole scale was 0.82 and for the three extracted factors of health, appearance in relation to others, and appearance in relation to oneself, were 0.86, 0.85 and 0.74 respectively. The results indicated the desirable internal consistency of the scale and its components. The outcome of confirmatory factor analysis supported the factor structure obtained from exploratory factor analysis and the fit indices demonstrated a good model fit. In general, it can be concluded that the Persian version of the WLM-Q has desirable psychometric properties and is a reliable instrument for research and clinical settings.

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.

Abstract
The purpose of this study was to design, make and evaluate the psychometric characteristics of a pain metaphorical perception questionnaire in Persian-speaking who suffer from chronic diseases. The method of this study was descriptive and psychometric and it was a survey type of research. At first, based on the cognitive analysis of Raiisi's pain metaphors (2021), nine metaphorical mappings were extracted, which were respectively object, causality, path and direction, human, place, taste, container, force, and circle. Based on obtained source domains, a questionnaire with 25 questions was created using a Likert response scale. The content validity of questions was evaluated by three cognitive linguistics experts, two health psychologists, three physicians, and two psychometric experts. No questions were found to be irrelevant or inappropriate. At last, the questionnaire was completed availability and voluntarily by 250 monolingual Persian-speaking patients with chronic diseases in 2022-2023. The results indicated that there was a reliability coefficient by using Cronbach's alpha for the whole questionnaire and its components. Moreover, the result of the factor analysis showed that this questionnaire consists of four factors including object, force, human, and causality, which explain 24.66% of the total variance of the factors. Consequently, the questionnaire on pain metaphorical perception has good validity and reliability for Persian speakers
