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
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
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.
