From Fallout: A Survivor Talks to Incest  Offenders (And Others), by moi.

Four major factors that contribute to molestation have been proposed and widely accepted (Finkelhor, 1984). They are sexual arousal, preferring children emotionally, being blocked from an adult relationship, and failure of the offender’s inhibitions. A reliable assessment of the offender’s dynamics is often difficult.  Information is provided to the offender in treatment, however, and he is invited to consider the information and share with his group which dynamics he thinks apply to him. Similarly, this book can help any unapprehended molester ferret out his own patterns. Survivors may also use the material to make some sense of their experience. (p 34).
