“…South American, Hispanic north-American, African, Eastern populations [17–26, 47, 66], only one study seemed to report internal consistency in the corresponding sample (Cronbach’s alpha = 0.89) [25]. Others reported some contributions to construct or factorial validity [23, 24], or evidence suggesting sensitivity to change [18–21, 26].…”

BackgroundThe Zarit Burden Interview (ZBI) was originally developed to assess the level of subjective burden in caregivers of people with dementia. The Involvement Evaluation Questionnaire (IEQ) is amongst the leading scales to assess caregiving consequences in severe mental illness. We aimed to compare the psychometric properties of the ZBI, a generic tool, and of the IEQ, a more specific tool to assess the consequences of caregiving in schizophrenia and related disorders.MethodsSecondary analyses of a 16-week, randomized controlled trial of a psychoeducational intervention in 223 primary caregivers of patients with schizophrenia or schizoaffective disorder. Psychometric properties (internal consistency, convergent and discriminative validity, and sensitivity to change) were evaluated for both ZBI and IEQ.ResultsInternal consistency was good and similar for both scales (ZBI: 0.91, 95% CI: 0.89, 0.94; IEQ: 0.86, 95% CI: 0.83, 0.89). Convergent validity was relevant for similar domains (e.g. ZBI total score vs IEQ-tension r = 0.69, 95% CI: 0.61, 0.75) and at least moderate for the rest of domains (ZBI total score, personal strain and role strain vs IEQ-urging and supervision). Discriminative validity against psychological distress and depressive symptoms was good (Area Under the Curve [AUC]: 0.77, 95% CI: 0.71, 0.83; and 0.69, 95% CI: 0.63, 0.78 – for ZBI against GHQ-28 and CES-D respectively; and AUC: 0.72, 95% CI: 0.65, 0.78; and 0.69, 95% CI: 0.62, 0.77 – for IEQ against GHQ-28 and CES-D respectively). AUCs against the reference criteria did not differ significantly between the two scales. After the intervention, both scales showed a significant decrease at endpoint (p-values < 0.001) with similar standardised effect sizes for change (-0.36, 95% CI: -0.58, -0.15 – for ZBI; -0.39, 95% CI: -0.60, -0.18 – for IEQ).ConclusionsBoth ZBI and IEQ have shown satisfactory psychometric properties to assess caregiver burden in this sample. We provided further evidence on the performance of the ZBI as a general measure of subjective burden.Trial registration(ISRCTN32545295).

“…Our study reveals, however, that significant changes in disruptive behaviour were maintained four months later. When the level of self‐efficacy of caregivers of individuals with schizophrenia increases, the burden of care decreases (Durmaz & Okanli ). Some studies have shown decreased expressed emotion (critical, hostile and/or over‐involved) after a parent's intervention (Sepulveda et al .…”
