Goal-attainment scaling, a method for evaluating individual or group treatment programs, involves setting up individualized treatment goals and scoring the attainment of goals from the most successful outcome (+2) to the least successful(–2).

Over-optimism about the benefits of therapy may cause problems with score validity; measures for external validation are suggested.Abstract Teaser
