Registered outcomes8
Each outcome the trial registered, primary first, in ClinicalTrials.gov's words.
| List | Outcome | Time frame | Description |
|---|---|---|---|
| Primary | Performance in everyday living score change | 3 months | Performance in everyday living score change will be measured using Canadian Occupational Performance Measure (COPM). The Canadian Occupational Performance Measure (COPM) has a client-centered design and measures outcomes according to three occupational performance areas (self-care, productivity, and leisure), examining self-perceived changes in the occupational performance of patients through a semistructured interview. At the beginning, patients start by identifying their difficulties according to the three occupational performance areas. They subsequently use a 10-point scale, ranging from not at all crucial (1) to extremely crucial (10), to identify the intensity of certain difficulties. For the top five problems or tasks selected by patients, the interviewer asks them to continue identifying their performance and satisfaction with their performance by using the same 10-point rating scale. |
| Secondary | Functional status score change | 3 months | Functional status score will be measured using the Direct Assessment of Functional Status-Revised (DAFS-R). DAFS-R assesses seven different domains of functional abilities by requiring the participant to carry out different tasks, two domains will be evaluated: dealing with Finances (score range 0-32) and shopping skills (score range 0-20), with higher scores indicating better functioning. |
| Other | Global cognitive function score change | 3 months | Global cognitive function score will be measured using the Montreal Cognitive Assessment (MoCA). Thirty items assessing multiple cognitive domains are contained in the MoCA: short-term memory (score range 0-5); visuospatial abilities (score range 0-3), cube copy task (score range 0-1); executive functioning (score range 0-1), phonemic fluency (score range 0-1), verbal abstraction (score range 0-2); attention, concentration, and working memory (score range 0-1), serial subtraction (score range 0-3), digits forward (score range 0-1), and digits backward (score range 0-1); language (score range 0-3), and repetition of complex sentences (score range 0-2); orientation to time and place (score range 0-6), with higher scores indicating better cognition. |
| Other | Semantic memory score change | 3 months | Semantic memory score will be measured using the Verbal fluency test. The verbal fluency test is a short test of verbal functioning. It typically consists of two tasks: category fluency and letter fluency. In the standard versions of the tasks, participants are given 1 min to produce as many unique words as possible within a semantic category (category fluency) or starting with a given letter (letter fluency). The participant's score in each task is the number of unique correct words. |
| Other | Selective attention and cognitive flexibility | 3 months | Selective attention and cognitive flexibility will be measured using the Stroop Test |
| Other | Sustained attention and set-shifting | 3 months | Sustained attention and set-shifting will be measured using the Trial Making Test |
| Other | Depression score change | 3 months | Depression score will be measured using the Geriatric Depression Scale - 15 (Short version). The Geriatric Depression Scale (GDS) is a 30-item self-report assessment used to identify depression in the elderly. In the Geriatric Depression Scale, questions are answered "yes" or "no." One point is assigned to each answer and the cumulative score is rated on a scoring grid. The grid sets a range of 0-9 as "normal", 10-19 as "mildly depressed", and 20-30 as "severely depressed". |
| Other | Qualitative motivation with the computerized training exercise | 3 months | Qualitative motivation will be assessed using semi-structured interview |
