AbstractBackground and objectives:The purpose of the present research was to investigate Theorical model and psychometric properties of Persian version of AEQ were translated in to Farsi research on these areas negleted, may be because of lacking appropriate instrument. In response to this deficit, pekrun and et al(2005) developed a self-report instrument measuring various achievement emotions that students commonly experience in academic setting. The instrument contains scales for measuring enjoyment, hope, relief, anger, anxiety, shame, hopelessness, and boredom in class, learing and test contexts.Methods: First, the AEQ were translated in to Faris. After the pilot studing and resolving the mistakes, the Questionnaire were carried out to a sample group consisting of 300 students who were studying in Islamic Azad university in Tehran. Psychometric properties and Factor analysis were used to analyze the collected data. Results:The results showed that the AEQ scales are acceptably reliable and valid, and most of Questionnaire scale have acceptable Fit with data.

Background: The clock drawing test (CDT) is a neuropsychological test that has been used as a part of evaluation & screening of adults with cognitive impairments.
Objectives: The aim of this research was study of possibility, reliability, validity and norm finding of Clock Drawing Test (CDT) in 392 elementary school children of Tehran city.
Methods: The samples were selected by random multi step cluster sampling method. Students with behavioral, emotional, mental and pervasive developmental disorders eliminated after performing teacher form of Children Symptom Inventory (CSI-4, Gadow and Sprafkin, 1994) and Raven Progressive Matrices (Raven et al, 1983). Then, test copy of reproduction memoir figures (Caffarra et al, 2002) and CDT (Cohen et al, 2000) accomplished by 392 participants.
Results: Data analysis showed that the reliability coefficient Cronbach’s Alpha was 0/765. None of the 8 criterion for numbering of CDT was not omitted. Furthermore, inter-rater reliability and test-retest reliability were equal. /95 and. /90 respectively. The structure validity of CDT was study by main component analysis method. The amount of sampling sufficiency by KMO measure was. /716 and Bartlett’s Test of Sphericity was meaningful, then the condition were suitable for performing factor analysis. The results of factor analysis with Promax rotation extracting 2 parameters include: 1- Clock construction, 2- Time conception, that explained about 63% of total variance. Also, the concurrent validity of CDT and test copy of reproduction memoir figures was very suitable.
Conclusion: The clock drawing test has a good reliability and validity for cognitive evaluation of children.

he present research is mainly focused on how to standardize and prepare a short form for MMPI-2 questionnaire among Iranian university students. The sample consists of 3578 college students (1763 male and 1815 female) at different educational levels (AA, BA, MA, and PhD) from eight provinces, who were selected via multistage cluster sampling procedure. An Iranian and shortened version of MMPI-2 consisting of 370 questions was used. To investigate the construct validity of Iranian Shortened Version of MMPI-2, and to evaluate its reliability the principal components factor analysis and Oblimin oblique rotation was used. Results showed that Cronbach's Alpha coefficient as an index of reliability was 0.84 at first. This coefficient was increased to 0.96 through the omission of some questions with a weak co-efficient correlation. Among the remaining 156 questions, thirteen factors were extracted using factor analysis, Oblimin oblique rotation, skewing diagram and explained variance percentile. These factors, as a whole, explained 40.15 percent of the total variance of the variables. The naming of the factors was according to the original MMPI-2 including: Psychasthenia (PT), Frequency (F), Hypomania (Ma), Schizophrenia (Sc), Correction (K), Hypochondriasis (Hs), Hysteria (Hy), Paranoia (Pa), Depression (D), Lie (L), Psychopathic deviate (Pd), Social introversion-extroversion (Si), and Masculinity-Femininity (Mf). General findings indicate that the shorted form of MMPI-2 qualifies psychometric properties for clinical use and research activities in Iranian culture, especially in university settings.
