Abstract
This study investigated psychometric properties of the Self-Assessment Manikin (SAM) for measuring emotion in Iran. Data came from the undergraduate students of Tabriz University. This study was designed and carried out in two stages. Via cluster sampling, 128 students participated in the study to provide a measure of reliability of the 9 items researcher-made test in order to evaluate pleasure and arousal. In the second study, 92 students were chosen to determine the validity and reliability of SAM. Validity qualities were obtained through Pearson correlation and repeated measurements ANOVA. Reliability was evaluated by using test-retest (done at two weeks apart) and Cronbach's alpha coefficient. Cronbach's alpha for the researcher-made test was 0.89 and 0.83 for the pleasure and arousal dimensions, respectively. Test-retest reliability coefficient for SAM and researcher-made test was in the range of 0.55-0.78. Concurrent validity ranged from 0.56 to 0.87 and the criterion validity was acceptabl. The results of the present study demonstrated that Self-Assessment Manikin (SAM) has promising validity and reliability and could be applicable to clinical practice and future researches in Iran.

Abstract
Given the importance of the self-compassion construct as a criterion for mental well-being, this research was conducted in order to investigate the psychometric properties of the Persian version of Self Compassion Scale. All students of Urmia Islamic Azad University in the academic 2010-2011 year were considered as the population of the study. Of this population, 220 students (99 males and 121 females) were selected randomly to participate in the study. The subjects responded individually to the self-compassion and beck depression questionnaires and big five personality scale at their classrooms. The collected data were analyzed by Pearson correlation test, independent t-test, and exploratory factor analysis. The results of the exploratory factor analysis revealed six factors with a value of higher than 1 that could were explain 63/47 % of the variance together. Indexes of the fitness of the confirmatory factor analysis model also confirmed six factor model of this scale. Results of the Pearson correlation showed negative relationship between the self-compassion, depression and personality traits, especially neuroticism. Alpha cronbach coefficients for the subscales and the total score of the scale were obtained in the range of 0/65 -0/92. Based on the results of this study, it can be concluded that the self-compassion scale enjoyed a quite well validity and reliability to be used in university student populations.

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
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.

Abstract
Psychological flexibility is a multidimensional trait that plays an important role in many areas of life, including mental health. Given the role of psychological flexibility, researchers have been interested in examining this feature, but do not have the tools to specifically measure psychological flexibility. The purpose of this research is to analyse the reliability and validity of the Persian version of the Psychological Flexibility Questionnaire so that in the absence of a short and specific scale for measuring psychological flexibility, it can help measure this feature in psychological research. For this purpose, 400 male and female students at Ferdowsi University of Mashhad participated in this study in the academic year of 2019-2020 using the multi-stage cluster random sampling method. Exploratory and confirmatory factor analysis were used to evaluate the construct’s validity and calculate the reliability of Cronbach's alpha. Factor analysis showed that this questionnaire has 5 factors, which are: positive interpretation of change, defining oneself as a flexible person, identifying oneself as an open and creative person, interpreting reality as dynamic and changeable, and interpreting reality as multidimensional. Agents together accounted for 59.83% of the variance of the entire questionnaire. The internal consistency of the items of the Psychological Flexibility Questionnaire was 0.89, which indicates the desired reliability of this questionnaire. Based on the results of exploratory factor analysis and confirmatory factor analysis in this study, the Psychological Flexibility Questionnaire has acceptable validity and reliability regarding students.

Abstract
The Personality Pathology Dimensions Assessment Questionnaire (DAPP-BQ) is a self-report tool used to assess the characteristics of personality disorder. However, its diagnostic validity has not been investigated in Iranian samples. The main purpose of this study was to investigate the diagnostic validity of the Personality Pathology Dimensions Questionnaire (DAPP-BQ) in couples using sensitivity coefficient and clarity-orientation. The method of this research, which is in the field of psychometric designs, is a subset of methodological studies. The statistical population of the study consisted of all couples referred to counseling centers in Tehran, of which 240 couples (120 as clinical group and 120 as normative group) were selected using available purposive sampling. In the present study, in order to investigate the diagnostic validity of the mentioned instrument with an emphasis on the cut-off point method, sensitivity coefficient and clarity orientation have been used. The findings showed that the scales of "intimacy disorder" and "low social relationships" from the dimension of "social avoidance", "conduct disorder", "narcissism" and "rejection" from the dimension of "antisocial behavior", "cognitive disorder", "insecure dependence" and "stubbornness and disobedience" from the dimension of "emotional disorder" and "impulsivity" from the dimension of "impulsive behavior" using both methods have diagnostic validity and can distinguish the clinical group from the normative group.

Abstract
Suicide models suggest that attempts occur when individuals have both a desire to die and the acquired capability for suicide, such as fearlessness about death (FAD), which is crucial for transitioning from suicidal desire to action (Ferm et al., 2022). This study aimed to examine the psychometric properties of the Acquired Capability for Suicide-Fearless About Death (ACSS-FAD) scale based on the Interpersonal Theory of Suicide (IPTS), assessing its factor structure, reliability, and validity among Iranian students. The ACSS-FAD was translated into Persian using back-translation and administered to 380 students from counseling clinics at Ferdowsi University, Imam Reza University, and Hakim Razavi University in Mashhad during the 2022-2023 academic year. Construct and convergent validity were evaluated through data analysis. Cronbach's alpha for all subscales and the overall scale indicated satisfactory psychometric properties across genders and the total sample. Confirmatory factor analysis confirmed the factor structure with good fit indices. Correlation patterns between subscales and the convergent validity with the Beck Scale for Suicidal Ideation demonstrated good validity. The Persian version of the ACSS-FAD shows good reliability and validity in the Iranian population, serving as a useful tool for screening and assessing imminent suicide risk in clinical and research settings.
