This study examined the effects of student supervision upon the social environment of York College male dormitory residents. All 132 male students living in a student run dormitory, and all 170 residents of a non-student adult supervised hall received the University Residence Environment Scale. Statistical analysis revealed that the respondents from the student operated dormitory scored significantly higher than the adult supervised residents on the following subscales: Emotional Support; Intellectuality; Order and Organization; and Student Influence. The student supervised group received significantly lower scores on two subscales: Traditional Social Orientation; and Competition. The findings indicated that a student operated dormitory can produce a comparable, and in many ways more effective social environment as compared to an adult supervised hall. It was recommended that York College continue to employ students as resident hall directors. The Office of Residence Life was urged to consider strengthening dormitory programming by providing additional scholarly, cultural and artistic presentations, providing reinforcement for achievement, and increasing coeducational interaction. Finally, it was also recommended that an extensive study of all on and off campus student living conditions be conducted to evaluate strengths and weaknesses of the entire residence life system.
