    Area of Science:

    • Gerontology
    • Neurology
    • Nursing Research

    Background:

    • Assessing functional changes in older adults with dementia is crucial for care planning.
    • Existing tools may not adequately capture functional decline in moderate to severe dementia.
    • A collaborative approach involving healthcare professionals can enhance measurement tool development.

    Purpose of the Study:

    • To develop and validate a reliable tool for measuring functional changes in older adults with moderate to severe dementia.
    • To leverage the expertise of nurse researchers and clinicians in creating a practical assessment scale.

    Main Methods:

    • Phase I: Collaborative development of a new scale involving 20 nursing assistants and 3 licensed nurses.
    • Phase II: Testing the scale's interrater reliability and criterion validity using 27 subjects diagnosed with dementia.
    • Utilizing a mixed-methods approach combining qualitative input and quantitative validation.

    Main Results:

    • The developed scale demonstrated significant correlation among raters, indicating strong interrater reliability.
    • Criterion validity was supported by significant correlations between the new scale and existing instruments.
    • The collaborative development process using staff expertise proved effective.

    Conclusions:

    • The newly developed scale is a promising, valid, and reliable tool for assessing functional changes in dementia patients.
    • The study highlights the value of interprofessional collaboration in developing clinical assessment tools.
    • Further research is warranted to confirm the scale's utility in diverse clinical settings.
