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

Abstract

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.

The experience of caregiving for children with rare musculoskeletal conditions: A qualitative study in Arthrogryposis Multiplex Congenita

“…Two coders were used to ensure rigorous coding process and a third reviewer was consulted in any case of disagreement. The themes were then categorized in domains and subdomains as they related to factors that highlighted additional burdens not captured by the Zarit Caregiver Burden Questionnaire 22,23 , such as areas of bene t and factors that enhanced their quality of life as experienced in caring for their child.…”

Caregiver burden and its sociodemographic determinants in family caregivers of patients with schizophrenia attending a psychiatric tertiary hospital in South Africa

“… 30 The ZBI-22 has also been validated among informal caregivers of patients with schizophrenia and found to be an appropriate tool by experts. 31 , 32 , 33 According to other investigators, the ZBI-22 is the gold standard for assessing family caregiver burden in patients with schizophrenia. 34 …”

“…Categorical variables were expressed as frequency and percentages (Table 1, Table 2, and Table 3). The prevalence of the four categories of severity of caregiver burden (none to low [0-20]; mild to moderate [21][22][23][24][25][26][27][28][29][30][31][32][33][34][35][36][37][38][39][40]; moderate to severe [41][42][43][44][45][46][47][48][49][50][51][52][53][54][55][56][57][58][59][60]; severe [61-88]) was also expressed as frequency and percentage with its 95% confidence interval (CI). The normality of the continuous variables was assessed with multiple measures including the skewness-kurtosis test.…”

Postural-motor development, spinal range of movement and caregiver burden in Prader-Willi syndrome-associated scoliosis: an observational study

“…Scores range from 0 (indicating no burden) to 88 (signifying very high burden). 17 In a previous study the ZBI has been demonstrated to be a good predictor of the impact of PWS on many aspects of the caregiver quality of life and thus could be considered an efficient instrument to capture the global impact of PWS on the caregiver. 18 The telephonic interview, lasting around 15 minutes, ensured anonymity in data collection.…”
