Action control is one of the self-regulation processes which allow people to form their goals, persevere, execute and convert these goals into objective actions. It is a kind of psychological mechanism that led people commit to a set of actions against other actions. Action control is one of the self-regulation processes which considerably affect family variables, academic, life skills, and psychological health. The present study was aimed to investigate psychometric properties of Action Control Scale in Iranian community. The Persian version of Action Control Scale was performed on 422 undergraduate students of Shiraz University. Internal consistency was calculated so as to examine the reliability of the measure; the validity of the scale was also investigated employing the factor analysis and convergent validity. Cronbach's alpha coefficient indicated the acceptable reliability of Action Control Scale. Factor analysis also indicated the involvement of 3 factors, namely Disengagement/ Preoccupation, Initiative/ Hesitation, and Persistency/ Volatility, in the aforementioned scale which altogether explain 35/93% of total variance. Action Control Scale is of acceptable reliability and validity and hence is an appropriate method for assessment of action control in the Iranian culture.

One of the most common researches of individual differences in psychology, is self- esteem. In recent years, as a result of "dual process model" that emphasizes the importance of reflective processes and automated processes, cognitive psychology studies focused on the two types of self-esteem: explicit self-esteem (ESE) and Implicit Self-Esteem (ISE). Objectives: The purpose of the present study was evaluation the psychometric properties (reliability and validity) properties of Name Initial Preferences Task (IPT) in Iranian society and its adaptation with the Persian language alphabet. Methodes: A descriptive correlational research was carried out on 420 subjects (239 male, 181 female) university undergraduates with stratified random sampling. Results: In study 1, the reliability of IPT with using Cronbach's alpha and split-half and test-retest within 14 days of the 280 samples obtained. in study 2, to determine the validity of IPT, along with IPT, The scales of RSES, PANAS, and GHQ was conducted on 140 subjects. Correlation between IPT in test-retest 84/0 and alpha coefficient and split-half, respectively, 87/0 and 89/0. Also IPT scores significantly correlated with GHQ (56/0), PA (44/0), RSES (30/0) and NA (36/0-) indicate convergent and divergent validity of the scale. Counclusion: The overall results showed that the reliability and validity of IPT is Competente for Implicit self-esteem in the Iranian society. The suitability of psychometric characteristics of this scale, it can be useful measure for evaluating the Implicit self- esteem of iranian in non-clinical populations. Similarity of this results with researches of foreign languages suggests that the suitability of the Persian language in the scale.

Numerous studies use the Exploratory Factor Analysis (EFA) method to reduce the data. Determination of the true number of retainable factors is the most crucial problem confronting researchers when using EFA. Common methods usually under/overestimate the number of factors. Objective: The present research aims to evaluate the common methods of determining the number of retainable factors and also introduce Parallel analysis (PA), as one of the most accurate methods of doing so. Method: The Parallel Analysis methodwas illustrated step by step using authentic examples with Syntax programming in SPSS. Results: The results showed that Parallel Analysis was an accurate method of determining the number of factors; however, its application is limited. Conclusion: Despite being accurate, PA is not well-known to researchers; in part, because it is not included as an analysis option in most popular statistical packages. Therefore, this paper elaborated on how to apply PA. The authors hope this effective method will be applied more in the future.

Background: ‘Differentiation of self’ is an important factor for a person to cope with stressors and improve mental health. Therefore, it is necessary to provide appropriate instruments to assess this construct. Objectives: The present research aims to study the psychometric properties of the Differentiation of Self Inventory - Short Form as an appropriate instrument for assessing differentiation of self in the Iranian society. Method: After translation and adaptation of the questionnaire, 384 undergraduate students at Shiraz University who were selected using random multi-stage sampling method, responded to it. The instruments used in this study consisted of Differentiation of Self Inventory-Short Form (DSI-SF) and General Health Questionnaire (GHQ). Results: The results of factor analysis showed that the structure of this questionnaire clearly referred to the four factors of differentiation including fusion with others, emotional cut-off, emotional reactivity, and I-position. Face validity was confirmed by experts, and correlation coefficient of each component with the total score was significant. Moreover, the significant negative correlation between DSI-SF scores and somatic symptoms, anxiety/insomnia, social dysfunction, and depression scores was indicative of concurrent criterion validity. For the validity of scale, Cronbach's alpha coefficient was desirable. Conclusion: The results of showed that the validity and reliability of DSI-SH is qualified for assessing the differentiation of self, and that it can be used as a useful instrument for assessing the differentiation of self in the Iranian society.The role ofculture was also discussed in this study.

Background:Heller defined familism as a specific from of social organization where the interests of the family group prevail over those of the individual family members.
Objective: The purpose of the present study was to investigate the reliability and construct validity of Familism Scale in undergraduate students of Ahvaz Teacher Training Centers.
Methods: 332 students (156 male and 176 female) of teacher training centers that were selected randomly using the multi-stage sampling method and completed Familism scale and 16 items of cohesion subscale of Family Adaptability and Cohesion Evaluation Scale (FACES-2).
Results: The factor analysis using the principal components analysis and orthogonal rotation (varimax) showed three factors (familial support, familial honor, and subjugation of self for family). Cronbach’s alpha coefficients were for the whole scale 0.73, for extracted factors 0.55 to 0.82, and Concurrent validity coefficient of Familism scale with FACES-2 was 0.21 (P<0.001). Confirmatory factor analysis of three-factor model with one modification index provides a parsimonious fit.
Conclusion: The results of this study indicated that the present scale is a valid and reliable measure for evaluating familism dimensions in students.

Background: Implicit theory of intelligence is one of the newest socio-cognitive strategies proposed in scholastic motivation.
Objective: The aim of the present study is to investigate the validity and reliability of the 14-item implicit theory of intelligence scale (IT IS-14) (Abd-El-Fattah & Yates, 2006) in the Iranian student society. This instrument is used to measure the incremental and entity theories.
Method: The sample in this study includes 350 B.A. students in Ahvaz Islamic Azad University and Masjed Soleiman Islamic Azad University. The data analysis was carried out through the use of confirmatory and exploratory factor analysis, Cronbach’s alpha and Pearson's correlation coefficients statistic methods.
Findings: The Cronbach’s alpha coefficients for the subscale of incremental theory and subscale of entity theory were calculated as 0.82 and 0.74 respectively. To estimate the criterion validity, Dupeyrat and Marine’s scale of implicit theories of intelligence were used, and the correlation coefficients for the subscales of incremental theory and entity theory were calculated at two scales which were significant at the level of 0.001. To calculate the construct validity, confirmatory factor analysis and exploratory factor analysis were applied. The results indicated that the structure of implicit theory of intelligence scale was fit with the data and all indexes of fitness confirmed the model’s fitness. In addition, exploratory factor analysis leads to extract two factors of incremental and entity theories of intelligence.
Conclusion: Given the calculated psychometric properties, researchers can apply this scale applied to investigate implicit theories of intelligence (beliefs about intelligence) in the student society.

Background: emotion regulation is one of the major components in understanding emotional development, psychological health and psychopathology.
Goal: The aim of the present study was to prepare a Persian version of the emotion regulation process strategies questionnaire and to examine its reliability and validity.
Method: The Persian version of the emotion regulation process strategies questionnaire was prepared using double-translation technique and administrated to 349 students, 124 males and 2225 females, whose ages ranged from 18 to 32 years. The reliability of the Persian version of the emotion regulation process strategies questionnaire was assessed via internal consistency, item-rest correlations and test-retest methods as well as factor analysis, correlations between subscales and criterion validity was applied.
Results: Cronbach’s alpha’s range (0/57 to 0/94) showed that the Persian version of emotion regulation process strategies questionnaire and its subscales possessed good internal consistency. Item scores and the total score of the corresponding subscales correlated significantly (r =0/48 to r = 0/71) and the test-retest correlation values (0/51 to 0/77) suggested that the scale is stable. Explanatory and confirmatory factor analysis supported the seven factor model of Persian version of the process of emotion regulation questionnaire. The degree of intercorrelation among the subscales was moderately high to substantial (0/31 to 0/87). Finally, with respect to correlation coefficient model between Persian version of the emotion regulation process strategies questionnaire’s subscales and positive affect, negative affect and depressive symptoms indicated relevant criterion validity.
Conclusion: The Persian version of the emotion regulation process strategies questionnaire has relevant psychometric properties for Iranian population as well as to use in research and clinical situations.

Background: Preparing a valid instrument to measure the basic psychological needs in Iranian populations is necessary for research purposes.
Objectives: The aim of this study was to examine reliability, validity, and exploratory factor analysis of a Persian version of the Basic Needs Satisfaction in General Scale (BNSG-S) in a sample of Iranian students.
Method: Five hundred and eighty four students (273 males, 311 females) were participated in this study, voluntarily. All participants were asked to complete the BNSG-S (Gagne, 2003), the Eysenck Personality Questionnaire-Revised Short Scale (EPQ-RS; Eysenck, Eysenck, & Barrett, 1985), Positive and Negative Affect Schedule (Watson, Clark, & Tellegen, 1988), and the Mental Health Inventory (MHI-28; Besharat, 2009).
Results: The results of exploratory factor analysis supported a single general factor of basic needs satisfaction in general and a three factor structure including Autonomy, Competence, and Relatedness. The convergent and discriminant validity of the BNSG-S were supported by an expected pattern of correlations between the scale and the measures of personality and mental health. All correlation coefficients between the mean scores on the BNSG-S and scores of the extraversion, neuroticism, positive affect, negative affect, psychological well-being, and psychological distress were statistically significant. Coefficient alpha estimates of internal reliability were between .83 and .91 for the BNSG-S subscales. Test-retest reliability of the BNSG-S was also calculated at the range of .67-.77. All correlations were statistically significant.
Conclusion: It was concluded that the BNSG-S can be considered as a reliable and valid scale to measure the basic needs satisfaction in Iranian samples.

Background: The feeling of shame is one of the most important moral self- conscious emotions which play a major role in interpersonal relationships and social adjustment. Therefore, it seems essential to provide instruments to measure this structure. Purpose: The present paper aims to provide the necessary preliminaries in order to use Shame Scale designed by Rizvi (2009) among Iranian university students. Method: In order to assess the validity of the scale, first, it was made sure that the data were normally distributed. Then, factor analysis with original components and varimax rotation method was used to discover factor structure. The correlation between this scale and other valid scales of measuring self-conscious emotions of shame was used as convergent validity and its correlation with happiness scale was used as divergent validity. Cronbach's alpha coefficient was also used to measure the scale reliability through the method of the internal consistency of items. Participants in this study were 231 university students (female=134 & male= 97) of Shiraz University and Shiraz University of Medical Sciences. Results: The results indicated that shame scale in Iranian population has a multiple-factor structure called ‘moral transgression' and ‘self-inadequacy’. The correlation between this scale and the self-conscious emotions scale indicated that Rizvi’s shame scale has a convergent validity. Moreover, the relation with happiness scale was used as the divergent validity index. The results were indicative of the fact that unlike two other components, moral transgression component did not have a significant relation with happiness. Furthermore, a comparison between boys’ and girls’ scores showed that females had higher scores in some components. Conclusion: In sum, results of this study confirmed convergent validity, divergent validity, and internal consistency of the scale suitable to be used in Iran. The shame scale being culture- dependent was discussed with regard to the results.

Academic delay of gratification predicts academic performance, motivation, self-regulation and self-efficacy in students. Due to the importance of academic delay of gratification in teaching-learning processes, there is a need for special tools proportional to the Iranian culture. The objective of this study was to examine the psychometric properties of Persian form academic delay of gratification scale, including reliability, validity, and factor analysis. The population consisted of Iranian high school students from Karaj (N = 600, 326 boys and 274 girls) who were selected based on multistage cluster sampling. They were tested by academic delay of gratification scale and motivated strategies for learning questionnaire. Test- retest reliability academic delay of gratification scale based on the results of two performance tests and its internal consistency by Cronbach's alpha coefficients were calculated and confirmed. To analyze the concurrent validity and to determine the validity factor motivation strategy-learning questionnaire was used, which indicated that concurrent validity is adequate. In addition, results indicated that the separate confirmatory factor analysis (CFA) for the male and female samples showed a goodness of fit with the data. The findings of factor analysis as well as the reliability and validity coefficients were similar to the previous studies conducted in the original culture. Regarding its good psychometric properties, the scale is an appropriate instrument to measure student's academic delay of gratification.
