The main purpose of this study was to investigate validity and reliability of Son, Robb, Charismiadji's computer literacyquestionnaire among virtual and non-virtual students inScience and Technology University of Tehran in 2013. A random-stratified method was applied to select the sample (n=250). Participants completed two questionn- aires: Sonand et al.'s Computer Literacy Scale (2011) and Herczeg and Kindsmüller'scomputer literacy test. Based on The results of exploratory factor analysis with principal axis factoringmethod and Varimax rotation was identified two integrative and significant factors. The first and second factors were named application and ability, respectively. These two factors were explained 46.279% of total variance of this test. The correlation of this test with Herczeg  and Kinds- müller's computer literacy test was significant and positive (.791) and also its internal consistency (α= 0.869) and test -retest reliability (r=0.958) were satisfactory. The results of multivariate analysis of variance indicated that virtual students had better function in terms of computer literacy in comparison with the non-virtual students (p<.01)

The spirituality and religious researchers have been focused on creating a measurement tool in recent years. However, this trend has been forsaken in spiritual health field so far. In order to introduce an efficient measurement tool, this research proposes a new spiritual health inventory. This is a practical research in the form of the questionnaire. The population pool included high school students of Karaj city. A number of 628 students were selected using multi level selection methods and were tasked to fill out the spiritual health and NEO-FFI questionnaires. A structure with eight components were developed using the principal component analysis (PCA). Finally based on scary test, six components were selected with varimax rotation. These components were as follows: religious  belief,  heart peace, spiritual aesthetics, self-acceptance,holy feeling, believe in miracle. These results also demonstrated that scores of extracted components are valid and reliable. Finally, the the correlation coefficients between spiritual health inventory components and NEOPI Factors were as expected. Conclusively, the results of this research indicates that spiritual health inventory test demonstrates reliable properties to be used as a spiritual health test in teenagers.

Self-differentiation as the core concept of Bowen’s family systems theory refers to individual’s ability of differentiating between affective and mind processes. In other words, achieving a degree of emotional independence so that one is able not be drawn in to the emotional pool of emotionally laden situations, and decides in an  autonomous and rational manner.

The present study aimed at investigating the factor structure and validation of Drake et al.(2015) ’s Self-Differentiation Inventory Short Form (SDI-SF)in Iran.

Using convenience sampling procedure, a national sample of 1503 people( 433 males and 1070 females) whose age range was 14 to 62 for males and 18 to 59 for females was selected among internet social networks users. Then the selected users answered the electronic version of DSI-SF.

Using principal components method and Varimax rotation, five factors were extracted. So the results of confirmatory factor analysis showed that the factor structure of the inventory had a good fitness to the gathered data. In addition to checking for the content validity of the inventory, the reliability index was calculated(α= 0.741), showing an acceptable internal consistency. 

the results of factor analysis confirmed the original factor structure of the inventory, the reliability indices were similar to the results of previous research. Therefore according to the results of the study SDI-SF is an reliable and valid measure for determining the level of self-differentiation in the Iranian population.

In this study present MMPI-ARF Standardization of reconstructed form of Minnesota multidimensional Personality Inventory in guidance school students at Aq Qala city and the research main question is raised whether reconstructed form of Minnesota multidimensional Personality Inventory (MMPI-ARF) in guidance school students in Aq Qala city has desirable psychometric properties? The research method is in the field of methodological research, with emphasis on psychometric. Statistical population constitute all Aq Qala city guidance school students that are 3239 persons (1056 girl students, , 1699 boy students and 34 boy students in non-profit school), which 100 students using a convenience sampling were selected as sample size. The instrument used in this study is reconstructed form of Minnesota Multiphasic Personality Inventory (MMPI-ARF) that has validity and favorable credit. To determine the questionnaire validity coefficient with an emphasis on internal consistency of questions is used Cronbach alpha methods and test-retest method to evaluate the coefficient stability, Also, to investigate the validity coefficient of validity used same type criterion, in this regard, Assessment questionnaire of personality pathology aspects (DAPP-BQ) and correlation between the two mentioned questionnaire using the Pearson correlation coefficient is used and finally used structural validity of hierarchical and determine the coefficient of resolution-oriented. And results showed that all reliability coefficients greater than 84/0 used Cronbach's alpha and coefficients greater than 89/0 used test-retest method with Spearman-Brown modified which shows the favorable reliability coefficient of present questionnaire in evaluated 28 scales. Also, Minnesota multidimensional personality questionnaire reconstructed form (MMPI-ARF) with Assessment questionnaire of personality pathology aspects in Aq Qala guidance schools adolescents has simultaneous validity; finally, it became clear that Minnesota Multiphasic Personality Inventory reconstructed form (MMPI-ARF) has an internal structure that includes 28 scales and 4 factors.

This study aims to examine the psychometric properties (reliability, validity and norms) of the Family (IFR) was performed. The study population consisted of all students in the school at the time of the study were enrolled in one of the Alborz High School. Data collection tools was use of the index pattern of family relationships. To test the hypothesis of classical psychometric theory analysis including exploratory factor analysis with principal components analysis and factor analysis to assess the validity of the index pattern of family relationships, the correlation between total score and subscales as convergent validity, the correlation between the assessment of family relationships with family adaptability and cohesion as a criterion validity, the alpha coefficient for internal consistency and test-retest estimates were used. Research results showed that the combination of these 3 factors(Understanding family, family ties, family cohesion) On the 297/60% of the variance of the index family relationships (IFR) to Explains. Can also be deduced that the proportion of the total variance of the first to third in the Index of Family Relations (IFR) is higher than any other factor. So the results of exploratory factor analysis and confirmatory factor analysis shows the validity test of the relationships in the community. Relationships between index scores with the assessment of adaptability and family cohesion (99%) is significant. These results reflect the criterion validity of the relationships in the community and the estimated coefficients indicate the reliability of the scale and subscales in both internal consistency and reliability.

Resilience is the ability of human beings to adapt and overcome threats and hardships. Resilience is affected by different factors. The present study uses the descriptive method that was carried out with the aim of intercultural comparison of resilience. Sample population included all of the university students of Tehran. 400 students were chosen through cluster sampling. Evaluation tool was the resilience questionnaire (Connor-Davidson, 2003) that was analyzed by factor analysis after completion by students. Findings showed that the resilience construct has a proper validity and reliability and includes five factors of purposivism, self-control, problem solving ability, belief and optimism. A comparison of the obtained results with the factor analysis results of the questionnaire in other countries (Spain, India and South Korea) showed that: the number of components and the questions related to each component of resilience construct is different in different countries. In addition, the purposivism and ability to self-control are more important in Iranian culture. So, intercultural differences should be taken into account while considering the resilience of people.
