Brief Summary

Horticultural therapy is one of the effective interventions for the person with dementia(PWD) which could increase their time engaging in leisure activities and decrease their time doing nothing. However, there are some limitations and constraints for PWD to participate in the horticultural therapy especially in the high-density cities (e.g. Hong Kong). This study aims to investigate the feasibility and preliminary effects of adopting home-based technology-enhanced horticultural activities. The program will consist of three face-to-face (F-T-F) horticultural activity training session for a group of 6-8 participants and then biweekly telephone follow-up for 8-week home-based horticultural intervention. Program evaluation will be conducted through focus groups with 15 participants with different levels of stress reduction after the intervention. It is hypothesized that the PWD and their caregiver will have a significant improvement in the cognitive function and behavioral symptoms of the PWD, an increase in the positive caregiving experience in the family caregivers, a reduction of the caregivers' level of stress and depressive symptoms, and enhancement of the quality of life of the family caregivers after the intervention.

Outcome Measures

Primary Outcomes (6)

  • The Chinese version of Positive Aspect of Caregiving scale (PAC)

    The PAC scale demonstrates the acceptable levels of internal consistency Cronbach's alpha 0.85 among the family caregivers of PWD in Hong Kong. Higher scores indicating more positive self-perceptions of caregiving. Comparisons of changes of Positive Aspect of Caregiving scale (PAC)will be considered as follows: T0 - T1

    At baseline (T0) and 11th week (immediately post- intervention; T1

  • The Chinese version of Perceived Stress Scale (PSS)

    Perceived Stress Scale contains 10 items with 5-point Likert-type scale rating from 0 (never) to 4 (very often). The total score can range from 0 to 40 with higher scores indicating higher perceived stress. Comparisons of changes of Perceived Stress Scale will be considered as follows: T0 - T1

    At baseline (T0) and 11th week (immediately post- intervention; T1

  • The WHOQOL-OLD BREF (HK)

    The WHOQOL-OLD BREF (HK) comprised 28 items and each item is rated on a 5-point Likert-type scale that ranged from 1 (very dissatisfied) to 5 (very satisfied), with a higher score indicating a better QoL. Comparisons of changes of The WHOQOL-OLD BREF (HK) will be considered as follows: T0 - T1

    At baseline (T0) and 11th week (immediately post- intervention; T1

  • The Chinese version of Center for Epidemiological Studies Depression scale(CESDS)

    The Chinese version of Center for Epidemiological Studies Depression scale is a self-reported measure of depression containing 20 items. Comparisons of changes of Center for Epidemiological Studies Depression scale will be considered as follows: T0 - T1

    At baseline (T0) and 11th week (immediately post- intervention; T1

  • MoCA-5-min

    MoCA-5-min assess participants' cognitive function over the telephone. MoCA-5-min comprises four domains: attention, executive function/language, orientation, and memory.Comparisons of changes of MoCA-5-min will be considered as follows: T0 - T1

    At baseline (T0) and 11th week (immediately post- intervention; T1

  • The Chinese version of the Neuropsychiatric Inventory-Questionnaire (NPI-Q)

    The Neuropsychiatric Inventory-Questionnaire evaluates the frequency, severity, and caregiver distress of 12 neuropsychiatric symptoms by using a 5-point rating scale..Comparisons of changes of the Neuropsychiatric Inventory-Questionnaire will be considered as follows: T0 - T1

    At baseline (T0) and 11th week (immediately post- intervention; T1

Study Arms (1)

Intervention Arm

EXPERIMENTAL

The program will consist of three face-to-face (F-T-F) horticultural activity training session for a group of 6-8 participants and then biweekly telephone follow-up for 8-week home-based horticultural intervention.

Device: The Aspara @ smart grower

Interventions

The program will consist of three face-to-face (F-T-F) horticultural activity training session for a group of 6-8 participants and then biweekly telephone follow-up for 8-week home-based horticultural intervention. The home-based program contains different horticultural, cognitive and multisensory stimulation activities such asking the PWD and the family caregiver to record the sense of touch and odor when taking care of the plant and the various changes of the plants by using the smart grower. Program evaluation will be conducted through focus groups with 15 participants with different levels of stress reduction after the intervention.
