Design outcomes

Primary

Measure	Time frame
Primary outcomes were self-criticism, depression, self-cutting episodes, and overall NSSI episodes (including self-cutting). Self-criticism (using the Self-Rating Scale - self-report questionnaire) and depression (using the Beck Depression Inventory-II) were assessed at baseline, week 1, week 2, week 3, and week 4 of treatment, 4 weeks post-treatment and 12 weeks post-treatment.	—

Secondary

Measure	Time frame
Secondary outcomes were desire to discontinue NSSI, likelihood of future NSSI, days of active suicide ideation, and days of suicide plans. A self-report questionnaire version of the Self-Injurious Thoughts and Behaviors Interview was used to obtain measures of NSSI, suicide ideation, suicide plans, and suicidal behaviors. Each of these thoughts and behaviors were measured at baseline, week 1, week 2, week 3, and week 4 of treatment. These were also measured over two follow-up time points, at 8 and 12 weeks post treatment.	—
