Tailored versus manualized interventions for dementia caregivers: The functional analysis-guided modular intervention

Area of Science:

• Psychology
• Clinical Psychology
• Gerontology

Background:

• Caregiver distress is a significant issue, often addressed with standardized interventions.
• Individualized approaches may better target specific caregiver needs and distress mechanisms.

Purpose of the Study:

• To develop and evaluate a functional analysis-guided modular intervention (FAMI) for caregiver distress.
• To compare FAMI's effectiveness against manualized therapies (CBT, ACT) and a waiting list control.

Main Methods:

• A randomized controlled trial was conducted.
• Participants received FAMI, manualized CBT, ACT, or were on a waiting list.
• Mixed-effect models and clinical significance analyses were used.

Main Results:

• All interventions reduced depression and anxiety post-treatment with large effect sizes.
• Depression symptom reduction was maintained at follow-up for all groups.
• FAMI demonstrated sustained long-term effects on anxiety and comorbidity.

Conclusions:

• FAMI is a promising individualized intervention for reducing dementia caregiver distress.
• FAMI shows particular strength in maintaining long-term therapeutic effects.
• Case formulation and modular interventions offer a valuable alternative to manualized treatments.
