BACKGROUND: The World Health Organization stresses the importance of accessible
and (cost)effective caregiver support, given the expected increase in the number
of people with dementia and the detrimental impact on the mental health of family
caregivers.
METHODS: This study assessed the effectiveness of the Internet intervention
'Mastery over Dementia'. In a RCT, 251 caregivers, of whom six were lost at
baseline, were randomly assigned to two groups. Caregivers in the experimental
group (N = 149) were compared to caregivers who received a minimal intervention
consisting of e-bulletins (N = 96). Outcomes were symptoms of depression (Center
for Epidemiologic Studies Depression Scale: CES-D) and anxiety (Hospital Anxiety
and Depression Scale: HADS-A). All data were collected via the Internet, and an
intention-to-treat analysis was carried out.
RESULTS: Almost all caregivers were spouses or children (in-law). They were
predominantly female and lived with the care recipient in the same household. Age
of the caregivers varied from 26 to 87 years. Level of education varied from
primary school to university, with almost half of them holding a bachelor's
degree or higher. Regression analyses showed that caregivers in the experimental
group showed significantly lower symptoms of depression (p = .034) and anxiety (p
= .007) post intervention after adjustment for baseline differences in the
primary outcome scores and the functional status of the patients with dementia.
Effect sizes were moderate for symptoms of anxiety (.48) and small for depressive
symptoms (.26).
CONCLUSIONS: The Internet course 'Mastery over Dementia' offers an effective
treatment for family caregivers of people with dementia reducing symptoms of
depression and anxiety. The results of this study justify further development of
Internet interventions for family caregivers of people with dementia and suggest
that such interventions are promising for keeping support for family caregivers
accessible and affordable. The findings are even more promising because future
generations of family caregivers will be more familiar with the Internet.
