Two Sessions of Coach-Delivered Core Transformation for Distress and Well-Being

The goal of this study is to learn if Core Transformation, a guided coaching process, lowers psychological distress in adults. It will also look at well-being, daily functioning, and whether any changes last over time. The main questions it aims to answer are: * Do people who have two Core Transformation sessions have less psychological distress after their second session than people who are still waiting for their sessions? * Do any changes last up to 12 months after the sessions? * Do participants feel better about the issue they chose to work on? Researchers will compare a group that has the sessions earlier with a group that has the same sessions about 2 weeks later (a waitlist group). Participants will: * Choose one moderate issue to work on * Be placed by chance into an earlier-start group or a later-start group * Have two one-on-one online video coaching sessions with a Core Transformation coach (a coach in training or a certified coach), about one week apart. Sessions are recorded. * Complete online surveys before the sessions; at about 4 weeks (after the sessions for the immediate arm, and before the sessions for the delayed treatment arm); at about 6 weeks (after the sessions for the delayed treatment arm); and for long-term follow-up at about 3, 6 and 12 months after the second session. Everyone in the study is offered the sessions.
