Validation of the Dutch RIS Eldercare Self-efficacy Scale for Family Caregivers of People with Dementia

Self-efficacy has positive effects on mental health of family caregivers of people with dementia (PwD) and has a direct relationship with positive aspects of providing care. Valid and reliable measures of self-efficacy are needed to evaluate effects of psychoeducational interventions. Aim of the current study is to evaluate the psychometric properties of the Dutch RIS Eldercare Self-efficacy Scale for measuring self-efficacy of family caregivers of PwD. Family caregivers who participated in the fifth measurement cycle of the Living Arrangements for PwD (LAD-)study were requested to complete a questionnaire on self-efficacy, socio-demographics, perceived pressure and role in the care for their relative with dementia (N = 479). Principal component analysis resulted in a three-factor solution (instrumental, self-soothing and relational self-efficacy). Internal consistency for the subscales was adequate. Small positive and negative correlations were respectively found with the Family Perceptions of Caregiving Role instrument and Self-Perceived Pressure from Informal Care scale, providing initial evidence for the construct validity of the Dutch RIS. The results indicate that the Dutch RIS has potential for research and clinical purposes. Future research should validate the instrument in different settings and populations.
