Feasibility of computerised positive mental imagery training as a treatment adjunct in in-patient mental health settings: randomised controlled trial

Background Positive affect and anhedonia are important but challenging targets for mental health treatments. Previous research indicates the potential of a computerised cognitive training paradigm involving generation positive imagery, termed imagery (PMIT), to increase reduce anhedonia. Aims Our main aim was investigate feasibility PMIT as affect-focused, transdiagnostic adjunct treatment usual patients in in-patient settings. Method We ran an open feasibility, randomised controlled trial with three parallel arms: usual; plus PMIT; active comparator, control training. Fifty-seven from two different clinics Germany were 1:1:1 ratio. comprised introductory session followed by eight 15-min sessions over 2 weeks. Clinical outcomes such (primary outcome measure) assessed at pre- post-training, further 2-week follow-up. Results Adherence good attrition low. The patterns results data not consistent specific effect on affect, more Conclusions indicate promise larger efficacy investigating Limitations include lack researcher blinding, small sample size pre-specified outcomes. Anhedonia may be suitable primary future trial.
