Impact of the covid-19 pandemic
Following the UK Government’s guidance on strict social distancing and remaining at home during the covid-19 pandemic, all non-essential face-to-face contact ceased on 17 March 2020. At this time, 64 participants had completed the study, 187 were still actively participating, and 27 had been recruited but not started therapy. A series of mitigating measures was undertaken, and PrAISED therapists received guidance (supplementary appendix 2). A protocol amendment to adapt trial procedures was approved, including delivery of the intervention via telephone or videocall.
