Evaluate the outcome and adjust
After implementing, honestly assess what worked, what didn’t, and what to do next.
Key takeaways
- What it is: After implementing, honestly assess what worked, what didn’t, and what to do next.
- Why it works: Outcome evaluation closes the PST learning loop: without it, a partial success is experienced as failure and a failure generates no actionable information. Structured outcome review teaches people to extract specific lessons ("the timing was wrong, not my capacity"), which builds problem-solving self-efficacy incrementally rather than leaving outcome interpretation to depressive bias.
- Evidence: Established clinical or therapeutic practice.
- Avoid: Treating partial success as complete failure and abandoning the approach — PST is iterative by design; the first solution attempt is expected to require refinement.
Why it works
Outcome evaluation closes the PST learning loop: without it, a partial success is experienced as failure and a failure generates no actionable information. Structured outcome review teaches people to extract specific lessons ("the timing was wrong, not my capacity"), which builds problem-solving self-efficacy incrementally rather than leaving outcome interpretation to depressive bias.
How to do it
- 1At the review point, assess: did the solution achieve the goal, partially or fully?
- 2If yes: note what worked and consider the problem solved or ready for the next stage.
- 3If no: diagnose whether the problem definition, the solution, or the implementation was the failure point.
- 4Return to the appropriate stage — redefine if the problem changed, generate new solutions if the chosen one failed.
What the evidence says
Clinical practiceOutcome evaluation and iterative refinement are built into the PST protocol; the learning loop structure is consistent with control theory models of self-regulation, and the full PST protocol including evaluation shows RCT benefits for depression.
Honest caveat: The evaluation phase is rarely tested in isolation; its contribution to PST outcomes relative to the other phases is not decomposed in published trials.

Common mistake
Treating partial success as complete failure and abandoning the approach — PST is iterative by design; the first solution attempt is expected to require refinement.
IX Coach prompts the evaluation check-in automatically, guides you through the diagnosis of what failed if needed, and routes you back to the appropriate PST stage rather than restarting from scratch.
