Primary outcome measures
28-item General Health Questionnaire (GHQ-28): score at the end of treatment for the immediate treatment group compared to score of the delayed treatment group at the same timepoint. Measured at pre-randomisation and end of treatment (for active arm) or at 3 months (for control arm). All will be assessed again at 3 months post-treatment to assess uncontrolled delayed effects.
Secondary outcome measures
1. Zarit Caregiver Burden Interview
2. Caregiver Strain Index
3. Geriatric Depression Scale (GDS-15)
In addition to the analysis at the primary endpoint, (uncontrolled) treatment effects at the end of follow-up relative to baseline and end of treatment will be analysed as a secondary endpoint. All measured at pre-randomisation and end of treatment (for active arm) or at 3 months (for control arm). All will be assessed again at 3 months post-treatment to assess uncontrolled delayed effects.
