Background and Aim: Psychological scales are increasingly used as important tools for assessment of intelligence, talents, academic achievement and personality characteristics and as a help in diagnosis of mental or personality disorders. Besides other methods of studying behaviors, these tools can be used for such purposes in schools, industrial and commercial organizations, public offices, universities and medical centers. This study aimed to assess psychometric properties of Depression-Anxiety-Stress Scale(DASS-42) in a sample of high school students in Kermanshah. Method and Materials: This was a psychometric study executed on Kermanshah high school students in 2003-2004 academic year. A total number of 400 students were selected through multi-stage cluster sampling. In addition to DASS-44, other scales used in this study include: Beck Depression Inventory (BDI), Zung Anxiety Scale (ZAS) and Studets’ Stress Scale (SSS).Data were analysed running SPSS-10 software. Findings: The depression subscale of DASS-42 showed a high correlation (0.849) with the BDI in a 0.01 level of statistical significance. The stress subscale of DASS-42 was also found to have a 0.757 correlation co-efficient with SSS, again statistically significant at a 0.01 level. The rates of Chronbach alpha for the depression, anxiety and Stress subscales of DASS-42 were found to be 0.94, 0.85 and 0.87 respectively. The KMO rate for the present study was 0.88 which indicates a large-enough sample size for factor analysis. The Cruet-Bartlett’s test also showed a chi-square rate of 0.794 with a degree of freedom equal to 861, which was again significant at a 0.01 alpha level.  Discussion: After factor analysis, the factors which showed high specificity measures were compared with those introduced by the original authors. Hence this study identified a three factor model which can be regarded as identical with the model introduced by the original authors.

Aim and Background: The aim of the present study was to develop a short form of the Persian version of the Cognitive Emotion Regulation Questionnaire (CERQ-P-Short) and to examine its reliability and validity. Methods and Materials: The CERQ-P was administrated to 420 (220 male and 200 female) Iranian university students in 2009-2010 academic year. Following stepwise omission of the items with the highest ‘alpha if item deleted’ on the basis of reliability analyses results, the CERQ-P-Short was constructed. The validity of this questionnaire was assessed through the principal component analysis using varimax rotation, correlations between subscales, and criterion validity. Findings: The results of Cronbach’s alpha (ranged from 0.68 to 0.82) showed that the nine subscales of the CERQ-P-Short possessed good reliability. Principal component analysis explained 75% of the variance and supported the original nine-factor CERQ model. The correlations among the subscales were moderately high. Finally, with respect to criterion validity, several CERQ-P-Short subscales were uniquely associated with symptoms of depression. Conclusions: The short form of Persian version of the Cognitive Emotion Regulation Questionnaire (CERQ-P) has good psychometric properties.

Aim and Background: Considering the verbal limitation in children, their low cooperation with therapist and lack of awareness of their emotions and actions have made their psychological assessment limited to the rating child behavior by parents or teachers or the use of behavioral observations. There is an urgent need to identify and apply diagnostic tools that can assess the child’s emotions from their perspective. Drawing a story is able to respond to these needs. Therefore, the aim of this study was to investigate reliability, validity and standardization of drawing a story (DAS) among the children in elementary school of Shiraz, Iran. Methods and Materials: 500 primary school students from Shiraz were selected through multistage stratified random sampling. Subjects performed DAS and child behavior checklist (CBCL) was filled out by their parents. Data was analyzed using Spearman correlation coefficient, Kappa’s agreement coefficient, Cronbach's alpha and one way ANOVA. Findings: Cronbach's alpha was 0.82 for emotional scale, and reliability was 0.69, 0.64 and 0.58 for emotional content, self-image and using humor, respectively. Convergent validity was calculated by determining the correlation coefficient with child behavior checklist (CBCL). It was used in the comparison of the validity of the differential scores of children in three groups (depressed, aggressive and normal). Conclusions: Results of this study showed that drawing a story has psychometric properties for utilizing in psychological research and clinical diagnosis.

Aim and Background: Aggression is common among adolescents all around the world. Therefore, the purpose of the present study was to examine the reliability and validity of the Aggressiveness Scale. Methods and Materials: The present descriptive and psychometric study was conducted on 607 students. The study subjects were selected from among 10-13-year-old students using multi-stage cluster sampling. All participants completed the Aggressiveness Scale and Harter&rsquo;s Academic Motivation Scale (to determine concurrent validity). Exploratory factor analysis, item-total score correlation, and reliability analyses were performed to examine the psychometric characteristics of the scale. In addition, the Samijima graded response model was used to determine the fitness of data and analysis. Findings: Factorial analysis showed that the Aggressiveness Scale is saturated by one factor and has satisfactory fitness scales. Aggression had significant relationships with academic motivation (-0.17), academic achievement (-0.41), school absenteeism (0.41), and discipline (-0.35) (P < 0.01). Cronbach&#039;s alpha coefficient of the scale was 0.82. The data related to question responses had a suitable fitness with the Samijima model and the test awareness function in the range of +0.8 to +3 was a characteristic continuum. The statistical analysis was performed in SPSS, EQS, and Multilog software. Conclusions: The Persian version of the Aggressiveness Scale had acceptable psychometric characteristics among adolescents. Therefore, it can be used as a valid instrument for psychological studies. Furthermore, preventing and reducing aggression, and informing families, managers, chancellors, and teachers regarding the symptoms and causes of this problem, and methods to resolve it are necessary.

Aim and Background: The present study evaluated the psychometric properties of the Anticipatory Social Behaviours Questionnaires (ASBQ) (Hinrichsen & Clark, 2003) in a student sample. Methods and Materials : The participants of the present study consisted of 460 students (280 women, 180 men) who answered the ASBQ and 284 students (198 women, 86 men) who completed the ASBQ, Social phobia and anxiety inventory (SPAI), Subtle Avoidance Frequency Examination (SAFE), Social Phobia Inventory (SPIN), and Social Phobia Scale (SPS). In addition, 55 socially anxious patients also answered the ASBQ. The independent sample t-test, multivariate analysis of variance, Pearson correlation, Cronbach&rsquo;s alpha, and confirmatory factor analysis (CFA) were used for data analysis. Findings: In the determination of criterion validity, the Pearson correlation coefficient of the ASBQ score with the scores of the mentions questionnaires was significant. The CFA replicated the two-factor solution for the 12-item ASBQ. Discriminant validity using independent t-test and multivariate analysis of variance illustrated a significant difference in the ASBQ score and its subscales between the two groups of with and without social anxiety. Furthermore, the internal consistency of the ASBQ, based on Cronbach&rsquo;s alpha, was high and acceptable and its test-retest reliability was also approved. Conclusions Hence, it seems that the Persian version of the ASBQ was a reliable and valid instrument for assessment of anticipatory social behaviors in our Iranian student sample.

Aim and Background: The aim of this developmental study was to determine the reliability and validity of the Aging Perception Questionnaire (APQ) in the elderly in Tehran, Iran. Methods and Materials: To estimate the psychometric properties of the APQ, 502 individuals (373 subjects aged 60-80 years and 129 subjects aged 50-59 years, and 49.4% men and 50.6% women) in Tehran were selected using convenience sampling. The multidimensional APQ, which consists of two parts, was distributed among the subjects. The first part evaluates the viewpoint about increasing age (aging), and the second part evaluates the experiences related to changes in their health. Findings: Data analysis showed that the internal consistency of the APQ for the first part consisting of 32 items was 0.82 and for the second part consisting of 17 items was 0.88. In addition, the internal consistency of each subscale ranged between 0.63 and 0.81. The stability coefficient for the two parts of the questionnaire was assessed using test-retest over the period of 2 months and was found to be significant for all subscales (P < 0.01). To assess the construct validity, the exploratory factor analysis (EFA) using principal components (PC) analysis was used. The sampling adequacy in the two parts was, respectively, 0.871 and 0.728, and the significance of Bartlett test indicated appropriate conditions for factor analysis. Based on these findings, the first part of the APQ was saturated with 7 factors and in total explained 50.24% of the total variance. The second part in the single-factor structure in terms of determination of the experiences of health-related changes was valid that explains about 36.21% of the total variance under these conditions. The significant correlation between scores of APQ components and subscales of the Quality of Life Questionnaire (P < 0.01) represented the criterion-referenced validity of the questionnaire. Conclusions: The findings showed that the APQ had appropriate reliability and validity for assessing perceptions of aging in Iranian elderly.
