摘要：The aim of this study was to investigate the psychometric characteristics of Islamic Life Style Test (ILST) among the adolescents; thus, after ensuring the content and formal validity of the test, it was done. The population was the students in the high schools in the city of Qom (15-20 years old) and 578 students were selected among them by cluster sampling. The research tools were the Islamic lifestyle test and religious orientation test. The data were analyzed by the factor analysis and MANOVA. After analyzing, 12 questions were corrected and 9 questions were deleted. The Cronbach's alpha was equal to 0.86. In the sample, the number of factors was 9 that it was similar to the original version, but some names were different. The factors were named as follows: worship, negative open-mindedness, continence, commitment, positive relationship, wisdom, the world-willingness, activeness, and incuriosity. These factors explained 39.42% of the variance of the adolescents' lifestyle. 8 questions were deleted in the factor analysis. The simultaneous validity of the two tests demonstrated a correlation of 0.70. According to the factor validity, convergent validity, and appropriate reliability of the Islamic Life Style Test-Adolescent Version (ILST-AV), it is suggested to use it for doing researches about the adolescents.
