The current study aimed to evaluate the reliability and validation of the Persian version of the Job Boredom Scale among Iranian teachers. The present study was descriptive-analytical, and we selected 500 teachers working in Tehran using the convenience sampling method. We collected data using Lee’s Job Boredom Questionnaire (1986), Schaufeli Work Engagement (2002), Maslach Job Burnout Questionnaire (1981), and Smith’s Job Satisfaction Questionnaire (1969). Exploratory factor analysis using principal components and confirmatory factor analysis were used to analyze the data. The results of the experimental study confirmed the factor structure of job boredom with 17 items; we classified all 17 items into uniformity, low arousal, and reluctance to work. The confirmatory factor analysis results confirmed the excellent fit of the three-factor model. Convergent validity coefficients of job boredom with burnout were 0.47, divergent validity coefficients with job satisfaction were -0.50, and job enthusiasm was -0.74. Also, the reliability of the questionnaire was evaluated by the test-retest method in quarterly periods, which had a significant correlation of 0.87 and a Cronbach’s alpha coefficient of 0.94, which showed the confirmation of reliability by the internal synchronization method. Therefore, researchers and practitioners can be suggested to use this tool in research related to determining job boredom and reviewing the job status of teachers.

This study aims to investigate the psychometric properties of the Goals and Aspirations inventory. In this applied study, a psychometric design was used and the statistical population consisted of students of Allameh Tabatabaei University during the academic year 2011–2012. Among the students of Allameh Tabatabai University, 250 people (115 girls, 135 boys) were selected through an available sampling method and answered the Aspirations Index (AI) and the Religious Orientation Scale (ROS). Validity and reliability, exploratory and confirmatory factor analysis were analyzed using SPSS-22 and Lisrel-8.8 software. The results of the first-order exploratory analysis confirmed the structure of the operational decade of goals and aspirations with 41 items in the Iranian youth population. In the second-order exploratory factor analysis, all ten subcomponents were classified into three indices: external, internal, and self-transcending aspirations. The results of the first and second level confirmatory factor analysis confirmed the good fit of the model and also the convergent validity of the questionnaire. Cronbach's alpha ranged from 0.77 to 0.86 for the components and was 0.90 for the intrinsic aspirations index, 0.90 for the external aspirations index, and 0.82 for the self-transcendence index. Therefore, researchers and educators can be suggested to use this questionnaire in research related to assigning goals and aspirations and, if necessary, use this instrument to provide a basis for reviewing adolescents' life goals.
