Adaptive Training (AT)
Participants in this group receive a combination of Goal Management Training (GMT) and computerised Working Memory Updating (WMU). For participants in the AT group, difficulty of the Working Memory Updating (WMU) training tasks is progressively increased in response to task performance.
Non Adaptive Training (NA)
Participants in this group receive a combination of Goal Management Training (GMT) and computerised Working Memory Updating (WMU). For participants in the NA group, difficulty of the Working Memory Updating (WMU) training tasks remains at a relatively low level throughout the training period.

PRIMARY outcome

Timeframe: From pre-intervention (Week 1) to post-intervention (Week 12).

Population: In the context of disruptions associated with COVID-19, a decision was made to focus on testing the feasibility of running the experimental condition (Adaptive training) initially and therefore no participant was assigned in the control group (Non-Adaptive training).

Number of people referred from NHS eligible for screening and those entering the intervention. This will be continuously monitored throughout the study period.

PRIMARY outcome

Timeframe: From pre-intervention (Week 1) to post-intervention (Week 12).

Population: From the N=14 people entering the AT group, N=5 dropped out and therefore we analysed data from the remaining N=9 individuals. In the context of disruptions associated with COVID-19, a decision was made to focus on testing the feasibility of running the experimental condition (Adaptive training) initially and therefore no participant was assigned in the control group (Non-Adaptive training).

Mean percentage of working memory training sessions completed (a total of eight) were calculated across participants.

Number of trials for which the outcome was an incorrect response (subject pressed the incorrect button within the response window), calculated across all assessed trials. Higher score indicates a worse outcome. Mean percentage change between pre and post intervention scores was calculated across participants.
