This measure was assumed to be unidimensional because is just intended to measure dimensions of religious practice. Principal Component Analysis is used to find dimensions or factors of this measure. The participants were 643 students of two public high schools, one private high school, one private Islamic High School, and one Islamic boarding high school. There were two practical dimensions that found in this PRHM scale, Obligatory Practice and Sunnah Practice. These results give different concept from Western religious theory which emphasizes public and private practices. Although Moslems practices can be private and public but the practices of Indonesian Moslems teenagers were patterned to two of this dimensions.AbstrakKonsep religiusitas Barat yang berbasis Kristen mungkin saja akan berbeda dengan religiusitas Indonesia yang berdasarkan Islam.
