The sample included 90 male prisoners from Rawalpindi, Lahore, and Peshawar district prisons. Subjects were divided into three groups based on the number of years imprisoned: (1) long stay, 5 years or more; (2) medium stay, 3 years or more but less than 5 years; and (3) short stay, 1 year or more but less than 3 years. Five most severe and five least severe problems perceived by prisoners were identified. Problems reported as most severe concerned outside prison problems, future worries, and psychological stresses. Specifically, prisoners wished time would go faster, felt guilty that their family was in trouble because of them, felt that life was being wasted, desired an honorable life after release, and missed someone. The preferred way of handling a problem was for prisoners to take care of it themselves. Implications of the study findings are discussed, and suggestions to improve prison conditions are offered. A list of prisoner problems is appended. 25 references and 3 tables
