: Compassion and mindfulness as a basis for psychological evaluation, in order to evaluate and activate the desired variable. Considering the fact that in the research background we found out the effect of the educational package on the desired component of the component as effective instruction, by the decentralization of the components Negative determination. For this purpose, 297 of all women under the sponsorship of a charity in Rudbar city based on the Morgan table in the year (1396) who had a depression diagnosis based on a score of at least 12 in the Beck Depression Test, were selected by random sampling of target audiences They were . In a intervention group, 15 (one) and a control group of 15 (single) were replaced. The present study was a semi experimental design with pretest-posttest design with control group. The tool was used by Self-employed Scheer Questionnaire (Scherer, Maddox, Mercury, Prentice, 1982). Multivariate analysis of variance (MANOVA) was used to analyze the data. The results show the significant effect of this educational package on self-efficacy in depressed female head of household. Research hypotheses were confirmed at the significant level (p <0.0001).

Background: Test fairness is one of the main challenges in transition from paper- pencil towards computerized adaptive testing (CAT). Aim: This study was aimed at investigating differential item function (DIF), assessing intervening factors in clarifying DIF and suggesting the optimal method for DIF in computerized adaptive testing. Method: The empirical method was applied based on the nature of the study area. Data gathering procedure and manipulating the variables were done using simulation method. The responses of 1000 examinees (reference and focal group with equal 500 numbers) to item bank of 55 dichotomous items were simulated based on 3-parameter logistic model with 20 iterations. Fifteen items were manipulated in terms of DIF type and magnitude and test impact was evaluated based on mean difference of comparison groups. Computerized adaptive test with 30 items was administered via Firestar software package. Analysis was done by logistic regression (LR) and item response theory-likelihood ratio test (IRT-LRT) and the methods were compared based on their power and type I error rate. Results: Type I error rate of likelihood ratio test was less than logistic regression. The power of the methods was influenced by type, magnitude of DIF and test impact. Comparing with logistic regression, Item response theory-likelihood ratio test had more power in detecting uniform DIF for the impact and no-impact conditions and it showed more power by increasing the magnitude of DIF. The two methods showed no difference in assessing non-uniform DIF and both of them were poor. Conclusion: Given the power and type I error rate, likelihood ratio test is an optimal approach in detecting uniform DIF. However, assessing non-uniform DIF requires further investigation.

In order to facilitate the interpretation of raw scores, they are usually converted to scale scores. In some cases, these conversions are a series of nonlinear transformations that can affect the conditional standard error of measurement throughout the scale of score. Therefore, the purpose of this study was to introduce methods for calculating the conditional standard error of measurement based on the strong true score theory. Furthermore, comparison of normalized and equipercentile nonlinear transformations on the raw scores of the academic achievements of the graduates of mathematical sciences in 2014 and their effect on conditional standard error of measurement was also conducted. So, in order to achieve these purposes, we used a sample of 3943 high school graduates of Mathematics and Physics in 2014 who had participated in national university entrance examination in 2015 randomly selected by National Organization of Educational Testing. The conditional standard error of measurement under these transformations was estimated based on the binomial procedure of Brennan and Lee (1999) and Chang (2006) method based on the beta-binomial distribution. The results of this study indicated that the conditional standard error of measurement of the Chang was smoother than binomial procedure, but in both methods the estimated errors are larger for middle points and smaller for extreme points. Additionally, the conditional standard errors of measurement of equipercentile were always less than normalized tranformation, so the equipercentile method found to be better than normalized transformation.

Abstract: Objectives: The purpose of this study was to assess psychometric indicators of students' Social- Emotional Competence Questionnaire (SECQ). Method: The sample size of this study was 518 high school female students selected by random sampling method from public secondary schools in Tehran and responded to the questionnaire. Findings: The results of exploratory factor analysis by main components method, in addition to general emotional-social competence, have 5 factors (self-awareness, social consciousness, self-management, relationship management and responsible decision-making) for the students' emotional-social competence questionnaire (SECQ), approved. To verify the reliability of the questionnaire, the Cronbach's alpha coefficient and the method of re-examination were used and a confirmatory factor analysis was used to determine its validity. The results showed that the questionnaire had acceptable internal consistency, and the Cronbach's alpha coefficients were below 0/77 to 0/80 in the sub-scales. The reliability of the questionnaire was obtained through a 0/86 test which was significant at the level of p

Abstract: Families with children with ADHD have specific problems and injuries that include all three couple, parent and sibling sub system. The purpose of this study was to construct and investigate the characteristics of damages of ADHD-based families’ questionnaire. For this purpose, using deep interviews with the phenomenological method with 16 families (27 people) and Studying the resources in the research background, the categories and damage of the three subsystems were identified and a questionnaire was developed based on them. Then among the families with a child with an ADHD disorder, 217 person were selected purposefully and questionnaire that was made was implemented on them. Cronbach's alpha method was used to determine the reliability and the marital conflict and quality of life questionnaire were used to determine the validity. Exploratory Factor Analysis was used. The results of the analysis showed that the Cronbach's alpha coefficient for the whole test was equal to 0/87, its coefficient of convergence with marital conflict questionnaire was 0/72 and the divergent credit coefficient with quality of life questionnaire was - 0/86. Result show that the researcher-made questionnaire has acceptable reliability and credibility with 11 factors and has the ability to identify the damages of subsystem of ADHD-centered family in clinical trials and family therapy. The value of this research is to design a native Iranian questionnaire to diagnose damages of ADHD families and apply appropriate treatment to these damages.

Psychometric Properties of Persian Version of the Movement Imagery Questionnaire-3 for Youth Abstract The purpose of this study was to evaluate the psychometric properties of the Persian version of the The Movement Imagery Questionnaire-3 for Youth. First, the original version of this inventory was translated into Persian and verified with forward-backward standard method, Then, 220 youth athletes (120 girls, 100 boys) who were engaged in Nahavand sports gyms were selected in randomized cluster sampling method and completed the questionnaire (12 questions). Content validity was evaluated through content validity ratio index (CVR), structural validity measured with confirmatory factor analysis by AMOS. The internal reliability of factors and total reliability of scales were also calculated from Cronbach's alpha. So, we can use this scale as a valid and reliable tool for measuring the ability of imagery in three dimensions, motor imagery, internal visual imagery, and external visual imagery. Key words: Mental Imagery, Visual Imagery, Validity, Reliability, Concurrent Validity, Internal Consistency.

The purpose of this study was to investigate the validity and reliability the episodic foresight test. This study is a descriptive- analytic one. The statistical population of this study was all children ages 3, 4 and 5 with low executive functions in kindergartens in Ahvaz city on 1397. In this study 60 children was selected by random sampling method, and responded to episodic foresight test (Atance & Meltzoff, 2005). To examine of the reliability of the instrument, the reliability indicator of the evaluators and the Kappa method and the Cronbach's alpha coefficient were used and, to determined the validity of the instrument, one-way analysis variance and binomial test were used. The result of the research showed that correlation between evaluators in scoring non-verbal section was 1.00 and in scoring verbal section was 0.99, and the Kappa correlation coefficient between the evaluators for each scenario was among 0.94 to 1.00, and cronbach's alpha coefficient was 0.75. To examine the validity of the instrument, the result of the binomial test showed that the children correct response rate was significantly higher than the response rate by chance. Also, the results of analysis of variance showed that there is a significant difference between children means score based on age and the Scheffe test showed that 3 years old children achieved scores lower than 4 and 5 years old children. But, there is no significant difference between scores of 4 and 5 years old children.

The purpose of this study Network data analysis application in family distance according to personality dimensions (NEO). Network analysis is a powerful method for analyzing communications between network members, which is a personality dimension and a graphical representation of matrix data. This research is a correlation study. In this research, which used cluster random sampling, 130 families with girls aged 11 to 20 from districts 1 and 3 of Tehran were chosen. The NEO Personality traits Inventory was used for data collection. The communication network depicted based on the data using network analysis technique and Fraterman-Reingold algorithm with qgraph and bootnet in software R. This pattern represented that between the subscales of personality, extraversion of the highest centrality, neuroticism had the highest negative connection and openness to experience had the least connection with other subscales. Conscientiousness-agreeableness had the most positive relationship and neuroticism-extraversion had the most negative relationship with each other.
