A Digital Health App to Prevent Falls and Improve Well-being in People Living With Dementia

The feasibility and acceptability of the intervention will be evaluated in terms of recruitment, retention and adherence rates to the trial. This will be evaluated by calculating the percentage of people approached who participate in the trial (recruitment) and the percentage of participants who complete the trial (including using KOKU-LITE and dementia and falls prevention leaflet and completing the questionnaires) (retention and adherence).

Health-related Quality of life as measured by The European Quality of Life 5 Dimensions (EQ-5D-5L) scale.

EQ-5D-5L is a 5-dimension version of the original EQ-5D scale. It has two sections: the EQ-5D descriptive system and the EQ visual analogue scale (EQ VAS). The 5 responses give a health state or profile represented by a 5-digit number (for example, 12231) corresponding to response categories reported by patients for successive dimensions: mobility, self care, usual activities, pain/discomfort, anxiety/depression. Current recommendations for scoring the EQ-5D-5L index will be followed. Index scores range from -0.59 to 1; 1 is the best possible health state. The EQ VAS records the patient's self-rated health on a vertical visual analogue scale where 0 indicates 'worst health you can imagine' and 100 indicates 'the best health you can imagine'.

The Erlangen Test for Activities of Daily Living test (E-ADL-Test) is a valid and reliable instrument for assessing the ADL capabilities of people with Dementia. It includes 4 domains: Pouring a drink, Cutting a piece of bread, Opening a little cupboard, Washing hands.

The total score of the E-ADL ranges from 0-30, with a higher score representing better results.

The Short Physical Performance Battery (SPPB) is a validated and reliable instrument to assess functional mobility in people with cognitive impairment/dementia. SPPB is a validated and reliable instrument to assess functional mobility in people with cognitive impairment/dementia. The SPPB test includes three different domains: walking, sit-to-stand and balance. The scores range from 0 (worst performance) to 12 (best performance).

The 5-item Geriatric Depression Scale screening tool for depression in older adults. The 5-item Geriatric Depression Scale screening tool for depression in older adults (validated to be as effective as the 15-item GDS for older adults in a wide range of settings). A score of 0 to 1 for the 5-item GDS suggests that the subject is not depressed, while 2 or higher indicates possible depression.

Falls risk will be measured with the use of the Assessment of falls risk (FRAT) tool. (VI) Falls risk will be measured with the use of the Assessment of falls risk (FRAT) tool. This validated measure has 5 items which include; history of any fall in the previous year, four or more prescribed medications, diagnosis of stroke or Parkinson's disease, reported problems with balance and inability to rise from a chair without using arms. These are all strong indicators for risk of falling. If a person scores 3 or more they are at high risk of falling.

The Short Falls Efficacy Scale-International (FES-I). The FES-I is a validated and reliable 7-item tool that measures confidence in performing a range of activities of daily living without falling. This scale has recently been modified to maximise its suitability for a range of different languages and cultures. Scoring: Minimum 7 (no concern about falling) to maximum 28 (severe concern about falling).

The User Experience Questionnaire (UEQ) is a standardized 26-item questionnaire that is used reliably to assess the quality and user experience of the interactive products. The standard interpretation of the scale means is that values between -0.8 and 0.8 represent a neural evaluation of the corresponding scale, values > 0,8 represent a positive evaluation and values < -0,8 represent a negative evaluation. The range of the scales is between -3 (horribly bad) and +3 (extremely good).
