In my review of the literature, I found only one author who found the primary long-term effects to be beneficial. 

Bernard (1981) 

Bernard conducted a descriptive and biographical study of 30 pedophile cases with a convenience sample. The children 

were ages 7-15 years. The sampling method used presents primary problems. The researcher states that the source of 7 referrals were through professional and personal contacts. Three of these were from therapists, but he fails to state the source of the remaining 23 cases. The problems of lack of a control group, small number of cases studied, combining age groups, and the use of clinical populations apply here as well as the probability of a biased, unrepresentative convenience sample. His evidence is not acceptable.
