Promoting and hindering factors of the intervention |
Measured using post-intervention qualitative interviews with intervention facilitators to capture descriptions of promoting and hindering factors in delivering the intervention and data to optimize the training, research design and the protocol. |
3 months (Primary time-point) |
|
Other |
Replication and dissemination of the intervention |
Measured by an observational protocol of the intervention sessions, including (1) in-session behavior, (2) participant engagement, (3) social interaction within the group, (4) peer support and (5) change in perception of living with dementia. |
Baseline to 10 weeks |
|
Primary |
Change in general self-efficacy |
Measured by the General Self-Efficacy Scale, a 10-item psychometric scale where each item is scored on a 4 point scale ranging from 'Not at all true' to 'Hardly true', to assess optimistic self-beliefs to cope with a variety of difficult demands in life. |
Baseline to 3 months (primary time-point), and 9 months after baseline (follow-up) |
|
Secondary |
Change in mood (anxiety, depression) |
Measured by the Cornell Scale for Depression in Dementia (CSDD) for participants with dementia. Scale ranges from 0-38, where high score indicates high symptom load. |
Baseline to 3 months (primary time-point), and 9 months after baseline (follow-up) |
|
Secondary |
Change in wellbeing |
Measured by the Sense of Competence Questionnaire Short version (SSCQ). This is a 7-item questionnaire, scale scores range from 7-35, where higher scores indicate higher sense of competence, which is an important factor in their wellbeing. |
Baseline to 3 months (primary time-point), and 9 months after baseline (follow-up) |
|
Secondary |
Change in Health-related Quality of life (HRQL) |
Measured by the Dementia Quality of Life Scale (DEMQOL) for participants with dementia. A 28 item interviewer-administered questionnaire with a score range of 28 to 112, higher scores indicating better HRQL. |
Baseline to 3 months (primary time-point), and 9 months after baseline (follow-up) |
|
Secondary |
Change in Health-related Quality of life (HRQL) |
Measured by the Dementia Quality of Life Scale (DEMQOL) proxy version. A 31 item interviewer-administered questionnaire answered by a carer with a score range of 31 to 124, higher scores indicating better HRQL. |
Baseline to 3 months (primary time-point), and 9 months after baseline (follow-up) |
|
Secondary |
Change in Quality of life |
Measured by EQ-5D-5L. Descriptive measure of quality of life comprising 5 Dimensions With 5 Levels each, scores can be converted to a single summary index number. A visual analog scale records self-rated health ranging 0-100, high score indicates good health. |
Baseline to 3 months (primary time-point), and 9 months after baseline (follow-up) |
|
Secondary |
Change in health behaviours |
Measured by Self-reported health behaviour change questionnaire. Comprises 17 questions about specific health-related change that occurred during each time period, and if yes, how much of a change ranging from 'a little change', 'quite a bit of change', and 'great change'. |
Baseline to 3 months (primary time-point), and 9 months after baseline (follow-up) |
|
Secondary |
Change in cognition |
Measured by the telephone Mini-Mental Status Examination (tMMSE). Assesses cognitive function in people with dementia. With a maximum score of 26, lower scores indicate greater cognitive issues. |
Baseline to 3 months (primary time-point), and 9 months after baseline (follow-up) |
|
Secondary |
Cognition and function |
Measured by the Modified Clinical Dementia Rating Scale (mCDR), a 5-point likert scale used to characterize six domains of cognitive and functional performance, level of impairment/dementia is ranging from 0=Normal, 0.5 = Very Mild Dementia, 1 = Mild Dementia, 2 = Moderate Dementia, 3 = Severe Dementia |
Baseline |
|
Secondary |
Change in function |
Measured by the Functional Activities Questionnaire (FAQ). 10 items measuring instrumental activities of daily living (IADLs), with sum score ranging 0-30. Higher score indicates impaired function. |
Baseline to 3 months (primary time-point), and 9 months after baseline (follow-up) |
|
Secondary |
Change in neuropsychiatric symptoms |
Measured by the Neuropsychiatric Inventory Questionnaire (NPI-Q), an informant based questionnaire assessing the presence and severity of 12 Neuropsychiatric Symptoms. Severity scores range from 0-36, where higher scores indicate more severe behavioural and psychological symptoms of dementia. Distress scores range from 0-60, where higher values represent higher levels of distress due to symptoms. |
Baseline to 3 months (primary time-point), and 9 months after baseline (follow-up) |
|
Secondary |
Change in carer stress |
Measured by the Relative Stress Scale (RSS), which consists of 15 items ranging from 0-4, high score indicates high burden on carers. |
Baseline to 3 months (primary time-point), and 9 months after baseline (follow-up) |
|
Secondary |
Change in knowledge about dementia |
Measured by the Dementia Knowledge Assessment Scale (DKAS). Comprising 25 items with statements about the condition, including general characteristics, symptoms, risk factors, care and treatment. Respondents answer on a modified Likert scale with five response options: false, probably false, probably true, true, don't know. |
Baseline to 3 months (primary time-point), and 9 months after baseline (follow-up) |
|
Secondary |
Change in perceived access to service use |
Measured by the Client Service Receipt Inventory (CSRI). A validated tool to gather information on current living arrangements, medication, use of hospital, community-based and day services. |

|
Secondary |
