Design outcomes

Primary

MeasureTime frame
1. Recruitment rate, recorded as the number of clients recruited at each site over a 6-month window 2. Treatment engagement, recorded as the number of clients who completed treatment with a planned discharge and as the number of clients attending at least 10 sessions (50% of acute treatment dose), measured at the end of the acute treatment phase 3. Satisfaction with treatment, recorded as the number of clients and therapists rating treatment as acceptable, satisfactory and that they would recommend it to others, measured at the end of the acute treatment phase 4. Patient safety, recorded as the number of serious incidents that could be clearly attributed to the intervention or research participation, measured over the duration of the trial 5. Preliminary signal of clinical efficacy, indexed as the number of clients showing at least reliable improvement and/or a positive change in slope/level in time series analysis of depression, anxiety and/or wellbeing (see list of secondary outcome measures below for details), measured at the end of the acute treatment phase

Secondary

MeasureTime frame
The following clinical outcome measures will be collected weekly during the baseline, treatment and 2-month post-treatment phase: 1. Depression symptoms measured using the Patient Health Questionnaire (PHQ-9) 2. Anxiety symptoms measured using the Generalized Anxiety Disorder Scale (GAD-7) 3. Wellbeing measured using the Warwick Edinburgh Mental Wellbeing Scale Short Form (WEMWBS-SF) The following clinical outcome measures will be collected at intake, pre-treatment, post-treatment, 2-month follow-up and 1-year follow-up extended assessment: 1. PHQ-9, GAD-7 as described above 2. Wellbeing measured using the Warwick Edinburgh Mental Wellbeing Scale full scale (WEMWBS-FS) 3. Personality disorder symptoms/features measured using the PDS-ICD-11 4. Anxiety symptoms measured using the Generalized Anxiety Disorder Scale (GAD-7) 5. Anhedonia symptoms measured using the Snaith Hamilton Pleasure Scale (SHAPS) 6. Life satisfaction measured using the DIALOG Scale 7. Quality of life measured using the Recovering Quality of Life Scale 10-item version (ReQoL-10) 8. Functioning measured using the Work and Social Adjustment Scale (WSAS) 9. The hypothesized mechanism of change in ADepT assessed using the ADepT Outcome Tool 10. At 1-year follow-up only a retrospective diagnostic interview will be used to assess if individuals met the criteria for a depressive episode over the past month All participants and therapists will be invited to take part in a qualitative interview after treatment is completed to explore their experiences of therapy
