This research administered with the aim of investigates the mediator role of perceived organizational justice in relation between personnel’s chronic self-concept with outcome, supervisor and management satisfaction. On the basis of this goal, from statistical universe, which include some industries and organizations in Esfahan city, persons selected for answer to the research questionnaires, with using two stage random sampling. Research method was correlational. Research questionnaires were: three questionnaires for organizational justice assessment (distributive with items, procedural with items and relational with items) a questionnaire for level of choronic self-concept assessment, and three questionnaires for assessment of outcome, supervisor and management satisfaction. Data analyzed with the use of Pearson’s correlation coefficient and mediator regression analysis. The first step of mediator regression showed that the individual and collective chronic self-concept (with and, standardized beta for distributive justice and with and standardized beta for procedural justice) have predictive power for distributive and procedural justice. Also collective chronic self-concept (with standardized beta) has predictive power for relational justice. But in predicting the outcome, supervisor and management satisfaction, by chronic self-concept dimensions, results showed that for outcome and supervisor satisfaction, individual and collective chronic self-concept (with 0& standardized beta respectively) and for management satisfaction only collective chronic self-concept (with standardized beta) have predictive power. Mediator regression analysis in third step, showed that only distributive justice play mediator role between collective self-concept with outcome satisfaction. But for supervisor satisfaction, procedural and relational justice play mediator role between individual and collective self-concept with supervisor and management satisfaction. And finally only procedural justice play mediator role between collective self-concept with management satisfaction.

The purpose of this study was to investigate the diagnostic validity of MCMI-III (Millon,) Scales in an Iranian population. The diagnostic validity of MCMI-III Scales was examined among psychiatric patients. Using operating characteristics (prevalence, sensitivity and specificity) of MCMI-III Scales, the predictive powers (positive, negative and overall) of the Scales was calculated. The results showed very good diagnostic validity for all MCM-III scales. Findings suggest MCMI-III Scales were found having high PPPs, NPPs and OPPs. The PPPs ranged from. to, and The NPPs ranged from to also OPPs ranged from to for all scales. Thus MCMI-III is a valid inventory and it can be used for Diagnosis personality disorders and clinical syndromes.

Ravens progressive matrices test is a reliable and valid intelligence test for mental testing and general intelligence. The advanced form (APM) of test was made for measuring the mind ability of superior and gifted people. The aim of this study was to test the reliability and validity of this instrument for intelligence testing in undergraduate student, and make a norm table of intelligence quotient (IQ). A randomized sample (n=) of undergraduate students of Islamic Azad university (khorasgan branch) population were selected and were tested, results showed that: The advanced form of Raven's progressive matrices (APM) test had significant reliability and validity (P<) for measuring intelligence of undergraduates. distribution of raw scores in this study was normal, therefore, we can obtain z scores (standard score) and compute IQ scores according to Wechsler scale (m=, s=). results showed no significant difference between male and female. different ages showed no significance differences after years old.

This research was carried out in order to evaluate understanding of fundamental mathematical concepts and the relation between cognitive mathematical abilities and performance of male and female elementary school students in Mazandaran based on Piaget’s theory. To fully objectives of this research hypotheses have been studied of which the first deal with those in Piaget’s studies. Population in this research comprises all male and female elementary school students in academic year in Mazandaran which has been selected trough accidental clustering sampling. First, four cities have been chosen then to elementary schools and finally testes (male, female) from each school have been selected the population has undergone Piaget’s mathematical recognition test and finally students have been selected from each grade the instruments utilized in this study are Piaget’s test Goodenough’s test, the grand mean of all lessons in the previous semester. Findings indicates that there is significant difference in Performance of students in 5 elementary grades in mathematical concepts abilities. There is significant difference between in elementary grades in spatial perception of point, concept of multiply and fraction, but there is not significant difference in other abilities. There is relation between cognitive mathematical abilities and difference elementary grade students. There is not relation between cognitive mathematical abilities and mental age. There is not significant difference between males and females mathematical concepts abilities. (P<)

This study was conducted with the aim of constructing and validating the scale for beginning to retirement syndromes in male and female beginning to retirees in Esfahan organizations in the spring of. In order to reach the goal of study, of begins to retirement, people from difference organizations selected with use of simple random sampling. A questionnaire with items beginners to retirement was developed using preliminary interviews, theoretical literature review, consulting authorities in the field, identify the factors indicating the retirement beginning to syndromes, i.e. the set of feelings and signs that beginners to retirement experience, and once pilot-tested on beginners to retirement on rolled with other organization, a questionnaire with questions was developed based on the previous questionnaire for group. The criteria for selecting questions were the presence of positive correlation with the whole test and positive factorial load of Once the questions were selected and tested on study samples of respectively, the reliability and validity of the tests was examined using the factor analysis (with use of principle components method and Varimax method of rotation). In factorial analysis, four factors capable of accounting for a total of of the total variance, were extracted the Cronbach's Alpha for the four factors were and respective being significant at P< level. The Cronbach's Alpha for the whole test, too, was estimated to be.

Marriage satisfaction has been always of importance to most of the practitioners and family counselors. Marital Satisfaction Inventory is one of the most applied tools which is developed to diagnose marital conflicts. In order to evaluate validity and reliability of this questionnaire it was translated into Persian language and was given to couples who had marital satisfaction problems, and couples who had no marital satisfaction problems. Cronbach's alpha coefficient and internal consistency of individual scales was, which is really high. Reliability coefficients demonstrate the high stability of individual scales with the highest one,. Differential reliability was computed to compare the two groups of satisfied and non-satisfied couples and it could be said that the difference between two groups is significant at. This test can really differentiate between two groups successfully. This study showed that the questionnaire can be used as a reliable diagnostic means of screening, treatment and clinical research about couples who have conflicts over and unsatisfied with their marital lives.
