- Acceptance and Action Questionnaire for Trichotillomania [Change from baseline (week 0) to post-treatment (week 10), 1-, 3-, 6- and 12-month follow-up.]
Total scores on the scale range from 9 to 63 with higher scores indicating a worse outcome (decreased levels of accpetance).
- The Skin Picking Impact Scale [Change from baseline (week 0) to post-treatment (week 10), 1-, 3-, 6- and 12-month follow-up.]
Total scores on the scale range from 0 to 50 with higher scores indicating a worse outcome (higher impact of skin picking).

The responses of the individual are weighted and calculated from 1 (full health) to 0 (death). The measure also includes a self-rated health scale, which ranges from 0 to 100, with higher scores indicating better self-rated health.
- Client Satisfaction Questionnaire-8. [Scores at post-treatment (week 10).]

The scale ranges from 12 to 84, with higher scores indicating a stronger working alliance.
- Clinical global impression - severity scale. [Change from baseline (week 0) to post-treatment (week 10)] and 12-month follow-up.]
Independent clinicians rate the severity of illness from "normal" (1) to "extremely ill" (7).
