Improving participation in voluntary activities in Iran is important because increasing productivity among young people, given the country's young population, contributes to community sustainability. Therefore, a better understanding of volunteer motivation in Iranian youth is needed. The Volunteer Functions Inventory (VFI) for assessing volunteer motivations has good psychometric properties and is adapted to several languages, but no validated Iranian translation yet exists. The purpose of this study was to investigate the psychometric Characteristics of voluntary functions inventory in members of Iranian Red Crescent Society. Sample size was 595 members of Youth Organization of Iranian Red Crescent Society from 31 provinces and 175 cities of Iran that were selected by multi-stage cluster sampling method and responded to voluntary functions inventory. Data were collected using a demographic sample and voluntary functions inventory (VFI). Confirmatory factor analysis using principal components method was used for data analysis. The results of the present study showed that the voluntary functions inventory had validity and reliability. Also, the factor structure showed that 29 items and 6 factors well assess people's attitudes to volunteering, and the structure of this inventory was well-fitted and confirmed all goodness of fit models. The present study provides the use of the Iranian translation of the Voluntary Functions Inventory (6 scales and 29 items) to assess volunteer motivation among young Iranian volunteers.

AbstractThe aim of this study was to investigate the validity, reliability and factor structure of the "How I Think" questionnaire to assess cognitive distortions in Iranian students. The present research design is descriptive and psychometric studies. The statistical population of this study included all male high school students in city Dezful in the academic year 1399-1400, from which 316 students were selected by multi-stage random sampling and completed the How I think and Bass and Perry Aggression Questionnaires (for Convergent validity). Factor analysis, Cronbach's alpha and Pearson correlation were used to analyze the data using SPSS and AMOS 20 software. The results of factor analysis showed that the questionnaire consists of six factors and has good fit indices. The convergent validity of this questionnaire indicated a satisfactory correlation between the dimensions of the scale "How I think" with the Aggression Questionnaire (p <0.01). Cronbach's alpha and Split- half coefficients for the whole scale and its dimensions ranged from 0.66 to 0.92.The conclusion is that the Persian version of the "How do I think" questionnaire for measuring cognitive distortions in Iranian students has acceptable psychometric properties and can be used as a valid tool in research, educational and clinical situations.

The Big Five Inventory (BFI) is one of the most widely used personality questionnaires, but very few studies have been conducted on its psychometric properties in Iranian population. This study was carried out with the aim of studying the psychometric properties of the BFI questionnaire. For this purpose, 390 university students in Tehran (210 girls and 180 boys) with an age range of 18 to 56 years (M = 27.52; SD = 8.79) were selected using the convenience sampling method and completed BFI and NEO-FFI questionnaires. Cronbach's alpha, multitrait-multimethod matrix, and confirmatory factor analysis were used to estimate the psychometric properties of the questionnaire. The result of the confirmatory factor analysis showed that 15 of the 44 items did not have a strong factor loading (higher than 0.40) on the corresponding factors and were therefore removed from the questionnaire. The fit indices showed that the Persian version of 29 questions (BFI-29) with 5 factors has a good fit with the data. The reliability analysis also showed that the range of Cronbach's alpha coefficients of the factors is from 0.70 to 0.79. The lowest Cronbach's alpha coefficient was related to agreeableness factor and the highest was related to conscientiousness. The findings from the multitrait-multimethod matrix showed that the BFI-29 questionnaire has good convergent and divergent validity with the NEO-FFI questionnaire. In general, based on the results of the present study, it can be said that the BFI-29 questionnaire has desirable psychometric properties and whenever a short tool for personality measurement is needed, this questionnaire can be used.

Phubbing is an emerging phenomenon in the world that has become more prominent in modern societies with the development of smartphones. With a practical purpose, this study has tried to standardize the phubbing Phenomenon Questionnaire and study and identify this phenomenon. The research method was correlational and its statistical population included the general population of users of smartphones and virtual networks. The sample size of the present study includes 408 people who were sampled by online questionnaires. In this study, the general phubbing scale (Chotpitayasunondh & Douglas, 2018), and the mobile phone addiction scale (Savari, 2014), and exploratory and confirmatory factor analysis were used to analyze the data. The findings of this study showed good validity and reliability for the phubbing General Scale Questionnaire. Also, the convergent validity between phubbing General Scale Questionnaire and Mobile Phone Addiction Questionnaire was 0/77. Based on the results, the phubbing General Scale Questionnaire can be used by the general population of Iran.

Due to the impact of dogmatism on many areas of individual and social life, much research is done focusing on this cognitive construct. However, since that there is no instrument in Iran for assessing Dogmatism, the aim of this study is to prepare Rokeach’s Dogmatism questionnaire and investigate its reliability and validity in Iranian students. Finally, 412 students were selected using multi-stage stratified sampling from Shahid Beheshti University students and completed the Persian version of Rokeach’s Dogmatism Questionnaire along with the Conservative thinking style subscale of Sternberg’s thinking styles Inventory. Data were analyzed using exploratory factor analysis by principal component analysis. Analysis showed that the questionnaire is composed of 12 factors having values above 1, which altogether explain 56 percent of its variance. Cronbach’s alpha was 0.75 for whole questionnaire and its correlation with the Conservative thinking style subscale was significantly positive. The results of the present study indicate that this questionnaire is relatively suitable for implementation in the Iranian student community.

Wisdom is one of the highest virtues and in the vast range of social activities, it ultimately improves itself and society. this study was aimed to examine the psychometric properties of The San Diego Wisdom Scale (SD-WISE). For this purpose, a sample of 350 students of Allameh Tabatabai University (223 females and 132 males) was selected by Stratified random sampling. and answered the SD-WISE questions, which consists of the six components of Social Advising, Emotional Regulation, Decisiveness, Insight, Pro-Social Behaviors, Tolerance for Divergent Values. The statistical characteristics, item analysis, validity coefficients, and exploratory and confirmatory factor analysis were used to assess the psychometric properties of the scale. The reliability of the questionnaire was calculated based on Cronbach's alpha equal to 0.81. The correlation between this scale and the three-dimensional wisdom scale was 0.56, which indicates the validity of the questionnaire.The results showed that after several runs of factor analysis and extraction of different solutions, five factors were extracted using the varimax method. Percentage of the variance shared by variables for the five factors, overall, can explain 54.236 percent of the total variance of variables. In addition, the model of confirmatory factor analysis was used to confirm the extracted factors, for which two models were compared and evaluated: the factor structure of the original version and the factor structure derived using the LISREL measurement model. The fit indices showed that the derived five-factor model has better fitness to the data than the original model.

A fundamental dimension along which all social and personal relationships vary is closeness. The purpose of present study was to investigate the factor structure and Item-Response parameters of the Unidimensional Relationship Closeness Scale. In a descriptive-correlational design and test validation 180 Birjand University students in the first study and 250 students in the second study were selected through multi-stage random sampling and completed the Unidimensional Relationship Closeness Scale (Dibel, Levin & Park, 2012). The data were analyzed by internal consistency, exploratory and confirmatory factor analysis, discrimination and threshold parameters and Item and test information curves. Results showed that the Unidimensional Relationship Closeness scale had a one-factor structure with explained variance of 63.39. Confirmatory factor validity was also confirmed. Cronbach's alpha coefficients were 0.95 and 0.93 and split half coefficients were 0.89 and 0.88, respectively in two studies. The Item-Response parameters were also at the optimum level. It seems that the Unidimensional Relationship Closeness scale, and in particular the structure of its 12 item versions, has a good reliability and validity in students.

The present study investigated the psychometric properties of a Persian version self- reassurance/ self-criticism Inventory in the male and female teachers. This study was of a validation type. The participants were 444 teachers selected through a multistage-cluster random sampling among the teachers in high school second period in the city of Bojnord of the 2015-16 years. The three scales administrated in this study were: self- reassurance/ self-criticism Inventory, self-efficacy Scale and happiness Inventory. A cronbach’s and test-retest reliability was calculated to examine the reliability of the self- reassurance/ self-criticism Inventory and to check the validity of the method convergent validity, divergent validity and confirmatory factor analysis was used. The calculated α for the inventory was for self-criticism 0.69 and for and self- reassurance 0.77. Neutralizing dimensions respectively self-criticism and for and self- reassurance examined through correlating it to the self-efficacy scale and happiness Inventory given signification. Using factor exploratory analysis confirmed the two-factor structure. The Persian version of the self- reassurance/ self-criticism Inventory seems satisfactory for measuring self- reassurance/ self-criticism symptoms in teacher's samples. Future research is, however, needed to confirm these data in a sample of OCD teacher's. Key Words: self-criticism, self- reassurance, Self-efficacy, happiness.

The main purpose of the present study was to investigate psychometric properties of the Perceived Stress Reactivity Scale (PSRS, Schlotz, Yim, Zoccola, Jansen & Schulz, 2011) among Iranian university students. 324 university students (130 male, 194 female) completed the PSRS and the Emotional Adjustment Measure (EAM, Rubio, Aguado, Hontangas & Hernandez, 2007). The confirmatory factor analysis method and internal consistency were used to compute the PSRS's factorial validity and reliability, respectively. Also, in order to examine the construct validity of the PSRS, we computed correlations between different dimensions of PSRS with emotional adjustment. The results of confirmatory factor analysis indicated that 5-factor structure of the PSRS consisted reactivity to work overload, reactivity to social conflicts, reactivity to social stress, reactivity to failure and prolonged reactivity had good fit to data in the Iranian sample. Correlational analyses between different dimensions of PSRS with emotional adjustment provided initial evidence for the PSRS convergent validity. Cronbach’s α Coefficients ranged from 0/75 to 0/80 for six dimensions. In sum, these findings provide evidence for the validity and reliability of the PSRS as an instrument to measure of stress reactivity among Iranian university students.

Studies of internationalmathematics achievement such as the Trends in Mathematicsand Science Study (TIMSS) have employed classical test theory and item responsetheory to rank individuals within a latent ability continuum. Although these approacheshave provided insights into comparisons between countries, they have yet toexamine howspecific attributemastery affects student performance and howthey canprovide information for curricular instruction. In the 2007 administration of TIMSS,two benchmark participants—Massachusetts andMinnesota—were tested followingthe same procedural methods, providing an opportunity for comparison within andacross the United States. Overall comparison of their performance showed Massachusettsand Minnesota to significantly outperform the United States. However,this article shows that there is a greater wealth of fine-grained information that canbe translated directly for classroom application at the attribute level when a cognitivediagnostic model (CDM) such as the deterministic, inputs, noisy, “and” gate (Junker& Sijtsma, 2001) model is used. Results showed a significant disparity betweenproportions of correctly answering and mastering skills required to solve an item.Advantages ofCDMsare discussed aswell as a CDM-basedmethod to filter distractorresponse categories that can aid instructors to diagnose a student’s attribute mastery.

The current investigation has been done for the purpose of the standardization of the social problem solving inventory (SPSI ) amongst students of the faculty of Psychology & Educational Sciences of Tabatabaey university in 1387-88. For this purpose, a sample of 200 students consisting 154 females and 46 males was selected based on categorical sampling, and the students were tested according to the social problem solving inventory ( SPSI) and social adjustment micro-scale of the adjustment questionnaire. Results showed that considering the Alfa value ( 0.85 )of the five factors measured, and the reliability value ( R = 0.88 ), the SPSI enjoys an acceptable rate of reliability. What’s more, the study of the factorial structure signifies the presence of 5 factors including ( APS ), ( RPS ), ( ICPS ), ( PPO ) and ( NPO ). Moreover the exploratory study of the relationship between the variables of the investigation showed that social problem solving ability would explain significantly social adjustment (R=0.304). In general, the results found in regards to the managing structure of the SPSI and the relation between the variables of the investigation, proved consistent with the precedent studies.

The The investigation of psychometric properties of epistemological belief scale in mathematics including reliability, validity and exploratory factor analysis was the purpose of this study. To achieve this end 464 university students (149 famales and 315 males), were selected through cluster rom sampling. The exploratory factor analysis were investigated through principal component method, this analysis confirmed six factors ( difficult problems, steps, understanding, word problems, effort and usefulness).To reach the concurrent validity of the scale, Schommer epistemological beliefs scale and Kloosterman and stage scale were conducted. The results of the analysis were acceptable. Test- retest reliability and internal consistency of the cronbach scale through, alpha coefficients confirmed. The results of factor analysis, conducted in the main culture and previous validity- reliability coefficient were closed to the studies. A psychometric property, of this scale allows applying to mathematical epistemological beliefs research.

his study examined the psychometric properties of a Persian translation of the Fennema-Sherman Mathematics Attitudes Scales among a sample of 400 Iranian high school students. A structural equation modeling strategy via Lisrel 8 (with item parceling procedure) was employed in estimating parameters. In addition, confirmatory factor analysis was conducted to assess construct validity of the nine latent variables, with each latent variable measured by 12 observed variables. The results of this study indicate an acceptable fit between the proposed model and the observed data. From all the 108 items (measured variables), 91 items correlated with their respective factors at a reasonably strong level. In general, the Persian translation of the FSMAS has acceptable psychometric properties. The fit of the proposed confirmatory factor analytic model provides evidence for the scale’s construct validity. The sample used in the present study may be minimally representative of the general population and replication is needed. .

The Big Five Inventory (BFI-10) is a shorter, 10 item version of the BFI. It was designed to be used when time limitations in a research protocol does not allow using the longer BFI. It measures personality in one minute or less. In this report, we evaluate 10-item measures of the Big-Five personality dimensions. The current study was conducted in survey and cross sectional as well as ex-post facto research context. A group of 317 randomly selected normal participants took part in this research. Principal component analysis extracted five factors which were labeled big five traits. However, for this scale other type of validity (convergent validity) and three reliabilities (test, retest, split half and internal constancy) were reported. The factor analysis and validity reliability coefficients demonstrated the same factor structure that previously found. Based on these results, it was concluded that BFI-10 contain good validity and reliability in Iranian population and it can be used, as valid measure in personality screening studies.
