This document summarizes Allen Tough's 1982 book "Intentional Changes: A Fresh Approach to Helping People Change". Tough conducted interviews with 150 individuals about significant intentional changes they made in the past two years. He found that the largest areas of change were career/job/training (33%) and human relationships (21%). Most changes were chosen, planned, and implemented by the individuals themselves, with little help from professionals. Tough concludes by outlining implications for improving how professionals help facilitate change and directions for future research on intentional changes.
