Abstract
This study investigated psychometric properties of the Self-Assessment Manikin (SAM) for measuring emotion in Iran. Data came from the undergraduate students of Tabriz University. This study was designed and carried out in two stages. Via cluster sampling, 128 students participated in the study to provide a measure of reliability of the 9 items researcher-made test in order to evaluate pleasure and arousal. In the second study, 92 students were chosen to determine the validity and reliability of SAM. Validity qualities were obtained through Pearson correlation and repeated measurements ANOVA. Reliability was evaluated by using test-retest (done at two weeks apart) and Cronbach's alpha coefficient. Cronbach's alpha for the researcher-made test was 0.89 and 0.83 for the pleasure and arousal dimensions, respectively. Test-retest reliability coefficient for SAM and researcher-made test was in the range of 0.55-0.78. Concurrent validity ranged from 0.56 to 0.87 and the criterion validity was acceptabl. The results of the present study demonstrated that Self-Assessment Manikin (SAM) has promising validity and reliability and could be applicable to clinical practice and future researches in Iran.
