Each outcome the trial registered, primary first, in ClinicalTrials.gov's words.
| List | Outcome | Time frame | Description |
|---|---|---|---|
| Primary | Number of participants able to complete the feasibility study as measured by retention rate | During 3 year study (Outcome Measure) | The primary outcome measure of this study is feasibility for this patient group, a retention rate of 75% will be considered feasible. |
| Secondary | Number of participants able to complete computerised HAPPYneuron pro cognitive training as assessed by task performance and the quality of the data generated. | During 3 year study (Outcome Measure) | The cognitive training programmes completed will be assessed. The level of achievement and quality of the data generated will be assessed. |
| Secondary | Symbol digit modality test | During 3 year study (Baseline Assessment and Outcome Assessment) | This is a simple substitution task to measure executive functioning. Using a reference key, the participant has 90 seconds to pair specific numbers with given geometric figures. |
| Secondary | Stroop tasks on paper of colour and work naming | During 3 year study (Baseline Assessment and Outcome Assessment) | In the stroop tasks, the participant is required to read words of colour names (e.g. red, blue) printed in black ink, and is asked to identify colours. This trial is intended to rule out colour blindness and ensure an adequate reading ability to complete the task. In the second stroop baseline trial, the subject must name the colour in which a word is presented, while ignoring the printed word. Thus, incongruence between the words colour and identity requires inhibition and response selection. |
| Secondary | Categorical verbal fluency (letter and categorical fluency test) | During 3 year study (Baseline Assessment and Outcome Assessment) | The fluency tasks require participants to verbally generate words beginning with a given letter (e.g. words beginning with the letter F) or category (e.g. animals). Participants are given one minute to retrieve as many words as possible and are instructed to avoid repetitions. |
| Secondary | Trail making A and B tests | During 3 year study (Baseline Assessment and Outcome Assessment) | This pencil and paper task uses randomly placed letters (and numbers for part B) as stimuli and participants must connect in sequence by drawing a continuous line with a pencil (e.g. from A-1-B-2-C-3 for part B). There is a brief sample for instruction purposes. |
| Secondary | Digit Span Forward subtest from Weschler's Adult Intelligence Scale (WAIS) | During 3 year study (Baseline Assessment, During Intervention and Outcome Assessment) | This task of working memory involves the participant being read a sequence of numbers and is asked to recall the numbers in the same order. |
| Secondary | Dual-tasking. Subjects are required to switch their attention between two competing tasks. Subjects will be asked to cross out a series of boxes whilst simultaneously recalling a digit sequence. | During 3 year study (Baseline Assessment, During Intervention and Outcome Assessment) | This test requires subjects to switch their attention between two competing tasks. Subjects will be asked to cross out a series of boxes whilst simultaneously recalling a digit sequence at a difficulty matched to their own digit span length. |
| Secondary | Tower of Hanoi | During 3 year study (Baseline Assessment, During Intervention and Outcome Assessment) | The Tower of Hanoi task has been used extensively as a test of planning ability in neuropsychological patients and normal populations to assess executive function. Participants are asked to preplan mentally a sequence of moves to match a start set of discs to a goal, and then to execute the moves one by one. |
| Secondary | Card sorting task of executive function | During 3 year study (Baseline Assessment, During Intervention and Outcome Assessment) | This is a neuropsychological test of "set-shifting", i.e. an executive function that reflects mental flexibility in the face of changing schedules of reinforcement. It requires subjects to identify a rule (e.g. a commonality between cards) and sort cards into groups according to that rule. |
