The aim of this pilot RCT is the development, implementation, and evaluation of a cognitive stimulation program with virtual reality for individuals aged 65 or older who have depressive symptoms and attend Portuguese day centers. The program aims to promote their cognitive functioning, well-being and functionality, and to reduce their depressive symptoms. A pilot study of the program will be conducted to assess its feasibility and preliminary efficacy.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Cognitive stimulation + VR | Experimental | Participants receive a cognitive stimulation program with virtual reality. |
|
| Wait-list Control | No Intervention | Participants assigned to the waitlist control condition remain on the waitlist throughout the study and are offered the intervention upon completion of the post-intervention assessment phase. |
| Name | Type | Description | Arm Group Labels | Other Names |
|---|---|---|---|---|
| Cognitive stimulation program | Behavioral | Twelve group sessions of a cognitive stimulation program with virtual reality. |
|
| Measure | Description | Time Frame |
|---|---|---|
| Adherence | The proportion of participants who complete all intervention sessions. Adherence will be considered achieved if at least 70% of participants complete all scheduled sessions. | Throughout the intervention period (6 weeks) |
| Acceptability and Feasibility | Acceptability and feasibility will be assessed through Theoretical Framework of Acceptability Questionnaire (TFA). All items are assessed on a 5-point Likert scale, with scores ranging from 1 to 5. Scores range from 7 to 35, with higher scores indicating better acceptability and feasibility. | Post-intervention (at week 7) |
| Acceptability and perceived barriers (semi-strutured interviews) | Acceptability of the intervention will be assessed through semi-structured interviews conducted with each participant after the intervention. The interviews will explore participants' overall evaluation of the program, including its perceived relevance, satisfaction with the intervention, and willingness to continue or recommend it. Perceived barriers to implementation will also be explored by asking participants to describe any difficulties or challenges they experienced during their participation. | Post-intervention (at week 7) |
| Measure | Description | Time Frame |
|---|---|---|
| Depressive symptoms | Changes in depressive symptoms will be assessed using the Geriatric Depression Scale (GDS-15), a 15-item questionnaire with yes/no responses, with total scores ranging from 0 to 15, where higher scores indicate greater depressive symptomatology. | Baseline, post-intervention (at week 7) and follow-up (3 months) |

| Well-being |
Changes in well-being will be assessed using the Warwick-Edinburgh Mental Well-Being Scale (WEMWBS). The scale consists of 14 items rated on a 5-point Likert scale ranging from 1 (never) to 5 (always), with total scores ranging from 14 to 70. Higher scores indicate greater levels of well-being. |
| Baseline, post-intervention (at week 7) and follow-up (3 months) |
| Functionality | Changes in functional ability will be assessed using the Lawton and Brody Instrumental Activities of Daily Living (IADL) Scale. The scale consists of 8 items and total score ranges from 8 to 30 points, with 8 indicating independence, scores between 9 and 20 indicating moderate dependence and scores above 20 indicating severe dependence. | Baseline, post-intervention (at week 7) and follow-up (3 months) |
| Global cognitive functioning | Changes in cognitive functioning will be assessed using the total score of the Neuropsychological Assessment Questionnaire that assesses multiple cognitive functions. The total score ranges from 0 to 112 points, with higher total scores indicating better cognitive performance. | Baseline, post-intervention (at week 7) and follow-up (3 months) |
| Visual attention and processing speed | Changes in visual attention and processing speed will be assessed using the Trail Making Test Part A (TMT-A). Performance is measured by the time required to complete the test, with longer completion times indicating poorer visual attention and processing speed. | Baseline, post-intervention (at week 7) and follow-up (3 months) |
| Executive functioning and cognitive flexibility | Changes in executive functioning and cognitive flexibility will be assessed using the Trail Making Test Part B (TMT-B). Performance is measured by the time required to complete the test, with longer completion times indicating poorer executive functioning and cognitive flexibility. | Baseline, post-intervention (at week 7) and follow-up (3 months) |
| Frontal executive functioning | Changes in executive functioning will be assessed using Frontal Assessment Battery (FAB), a brief screening tool composed of 6 subtests. Total scores range from 0 to 18, with higher scores indicating better executive functioning. | Baseline, post-intervention (at week 7) and follow-up (3 months) |
| Attention and immediate verbal memory | Changes in attention and immediate verbal memory will be assessed using the Digit Span Forward subtest of the Wechsler Adult Intelligence Scale-III (WAIS-III). Performance is measured by the number of correctly recalled digit sequences, with higher scores indicating better attention and immediate verbal memory. | Baseline, post-intervention (at week 7) and follow-up (3 months) |
| Working memory | Changes in working memory will be assessed using the Digit Span Backward subtest of the Wechsler Adult Intelligence Scale-III (WAIS-III). Performance is measured by the number of correctly recalled digit sequences in reverse order, with higher scores indicating better working memory performance. | Baseline, post-intervention (at week 7) and follow-up (3 months) |
