Design outcomes

Primary

MeasureTime frame
Phase 1: 1. Uptake rate is recorded as the number of eligible participants who consent to participate in the study 2. Initial engagement rate is recorded as the number of eligible participants who complete at least 2 sessions Phase 2: 1. Quality of life is measured using the McGill Quality of Life Questionnaire (Cohen et al., 1995) at baseline, 6 months and 9 months post-randomisation

Secondary

MeasureTime frame
Phase 1: 1. Acceptability: 1.1. Satisfaction rate is recorded as the number of eligible participants who consent to participate in the study and give ‘satisfactory’ ratings of therapy using the Satisfaction with Therapy and Therapist Scale-Revised (Oei et al., 2008) at 6 months. There is no set definition of what constitutes “satisfactory” and so this will be defined as a total score of 21 or more on the Satisfaction with Therapy subscale 1.2. Failure to recruit rate due to lack of acceptability is recorded as the number of eligible participants who refuse to consent to participate in the study during the 4-month recruiting period due to lack of acceptability of the intervention 1.3. Attrition rate due to lack of acceptability is recorded as the number of eligible participants who consent to participate in the study that drop out due to lack of acceptability of the intervention by 6 months 2. Feasibility: 2.1. Referral rate is recorded as the number of eligible referrals to the study overall during the 4-month recruiting period 2.2. Failure to recruit rate for reasons other than lack of acceptability is recorded as the number of eligible participants who refuse to consent to participate in the study during the 4-month recruiting period for reasons other than dissatisfaction with therapy 2.3. Attrition rate for reasons other than lack of acceptability is recorded as the number of eligible participants who consent to participate in the study that drop out for reasons other than dissatisfaction with therapy during the 4-month recruiting period 2.4. Deliverability of the intervention within the NHS is recorded as the number of therapy sessions offered (as opposed to completed) during the 3-month therapy period 3. Patient-reported outcome measures: 3.1. Quality of life is measured using the McGill Quality of Life Questionnaire (Cohen et al., 1995) at baseline and 6 months 3.2.
