Zarit Caregiver Burden Interview: Psychometric Properties in Family Caregivers of People with Intellectual Disabilities

Caregivers of people with intellectual disabilities may feel overburdened in their work and experience negative psychological consequences. The purpose of this instrumental study was to determine the evidence of internal structure and reliability of the Zarit Caregiver Burden Interview scale. A total of 398 family caregivers, including women and men, participated (M = 47.33, SD = 10.44). The structure of the scale was evaluated by factor analysis and the McDonald Omega coefficient was used to estimate reliability. Sixteen models of the scale were tested, differing in number of items and factor structures. A model of 15 items and 4 dimensions (overload, competence, social relationship, and interpersonal relationship) obtained acceptable fit (χ² = 184.72; p < 0.001; CFI = 0.95; TLI = 0.94; RMSEA = 0.055; SRMR = 0.05) and reliability coefficients above 0.70 in their dimensions. It is concluded that the Zarit scale is valid and reliable for use in caregivers of people with intellectual disabilities.

Mobile Care System for Older Adults: perceptions about its use in caring for people with dementia

Abstract Objective: To analyze the perceptions of caregivers and health professionals about a mobile application used for the caring and social support of people with dementia. Method: A qualitative study was performed on the experience of implementing a Mobile Care System for Older Adults (Sistema Móvel de Assistência ao Idoso, SMAI) in the routine of caregivers of people with dementia, treated at an outpatient clinic for cognitive disorders. Data were obtained through the application of questionnaires about the characteristics of caregivers and the Zarit scale to assess the level of burden. An Activities of Daily Living Questionnaire (ADLQ) was applied for functional evaluation. The perception of caregivers and professionals were collected through the audio recording of focus groups and analyzed according to the thematic-categorical analysis technique. Results: Twenty caregivers and five health professionals participated in the focus groups. Categories that emerged from the study revealed themes related to users’ experiences, communication, medication management, feelings of caregivers, patient management strategies, impact of dementia on caregivers’ lives, illness of caregivers and application evaluation. Conclusion: Interventions using mobile applications can help improve communication and social support in the care of dementia. The experience with the SMAI and its applications represented an innovative opportunity for both family caregivers and healthcare professionals.
