HOLIDAYS
Referrals were from the IAPT program. People experiencing depression were also invited through general practitioners and social media to self-refer to IAPT and, if eligible for self-help treatment in IAPT, were assessed for eligibility. Potential participants had a copy of the participant information sheet and the opportunity to ask questions before giving informed consent.Participants completed measures online (with postal option). Participants completed baseline measures with a research assistant present in person or by phone. At the end of baseline, eligible participants were randomized. Participants were then sent their allocated self-help workbook and asked to guide themselves through with 6 Psychological Well-being Practitioner (PWP) 30-minute to 45-minute support sessions. Up to 16 weeks was given to complete each intervention to allow for breaks and holidays. The PWP support sessions were offered by phone or face-to-face, depending on service practice and, where services offered a choice, participant preference.Participants had the option to complete assessments at 16 weeks and 42 weeks with a research assistant present in person or by phone or on their own. Where 16-week and 42-week assessments were not completed, weekly reminders were sent for up to 1 month.
