Abstract
Introduction: Collective disasters, especially those involving infectious diseases, often increase the wave of fear and anxiety that causes widespread disturbances in the behavior and psychological well-being of many people. The purpose of this study was to construct, establish and validate a questionnaire on the psychological dimensions of the Corona epidemic in 1399. Methods: The sample consisted of 542 people who were invited to cooperate with the available method and online. For this purpose, a questionnaire was prepared based on the theoretical literature and existing research in the field of the corona epidemic. In this study, the psychosocial dimensions of the corona pandemic consist of 5 sub-scale: generalized anxiety disorder, quarantine, and social distancing, coping skills, and frustration, and suicide. Initially, items were formulated for each dimension, and after formulating the initial questions, face validity, content, and reliability (internal consistency) were measured. Results: The results showed that by removing some items, the questionnaire with 28 items and 5 dimensions has significant validity. (Validity of 0.74 in the whole test and 0.68 to 0.95 in the subscales). Conclusion: The results show that by using this test, the psychological dimensions of the coronavirus epidemic can be identified.

Abstract
Fear of death is a global and cultural issue. The aim of the present study was to develop and validate a scale for afterlife fears in the Iranian sample. This study was an exploratory sequential mixed method design. The Qualitative phase included semi-structured interviews with 12 acute cardiac patients. The content of patients answers about afterlife fears rearranged as 14 items for quantitative phase. At the quantitative phase, 313 subjects (230 women and 83 men) were selected from Tehran city and carried out the questionnaires online. For studying construct validity of Afterlife Fear Scale, the responses of normal sample analyzed by exploratory factor analysis method. For assessing the concurrent validity of new Afterlife Fears Scale, its correlation with the Beck Depression Inventory (BDI-II, 1996) and the Rosenberg Self-Esteem Scale (SES, 1965) were calculated. Data analysis was performed using Pearson correlation coefficient, exploratory factor analysis, principal component extraction method and parallel analysis. Three factors were extracted which were named as "fear of punishment and grave torment", "loneliness and abandonment" and "longing and confidence in God", respectively. The internal consistency method was used to determine the reliability of the scale. Cronbach's alpha coefficient of the subscales ranged from .63 to .88, which indicated the appropriate internal consistency of the scale and its components. The Afterlife Fears Scale has good reliability and validity in the Iranian Muslim sample and can be used to identify the underpinning fears of cardiovascular patients and anxiety reduction interventions, as well as cross-cultural comparisons.

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.
