Allen Tough studied intentional changes among adults through interviews with 150 individuals about the largest change they intentionally made in the past two years. He found that nearly a third reported a huge change, most commonly in career, relationships, or activities. Individuals themselves were the primary resource for choosing, planning and implementing these changes, with professionals playing a small role. Tough outlined implications for improving support of intentional changes, including better help with goals and planning, and ensuring individuals retain most control over the change process. He remained optimistic about the future potential for supporting intentional changes.
