Validation of the 36-item version of the WHO Disability Assessment Schedule 2.0 (WHODAS 2.0) for assessing women's disability and functioning associated with maternal morbidity

Abstract

Objective To validate the translation and adaptation to Brazilian Portuguese of 36 items from the World Health Organizaton Disability Assessment Schedule 2.0 (WHODAS 2.0), regarding their content and structure (construct), in a female population after pregnancy. Methods This is a validation of an instrument for the evaluation of disability and functioning and an assessment of its psychometric properties, performed in a tertiary maternity and a referral center specialized in high-risk pregnancies in Brazil. A sample of 638 women in different postpartum periods who had either a normal or a complicated pregnancy was included. The structure was evaluated by exploratory factor analysis (EFA) and confirmatory factor analysis (CFA), while the content and relationships among the domains were assessed through Pearson's correlation coefficient. The sociodemographic characteristics were identified, and the mean scores with their standard deviations for the 36 questions of the WHODAS 2.0 were calculated. The internal consistency was evaluated byCronbach's α. Results Cronbach's α was higher than 0.79 for both sets of questons of the questionnaire. The EFA and CFA for the main 32 questions exhibited a total variance of 54.7% (Kaiser-Meyer-Olkin [KMO] measure of sampling adequacy ¼ 0.934; p < 0.001) and 53.47% (KMO ¼ 0.934; p < 0.001) respectively. There was a significant correlation

Validation of the Brazilian Version of WHODAS 2.0 in Patients with Mental Disorders: Should the 12-Item Scale be an Alternative to 36-Item Scale in DSM-5?

“…The difference between both structures is due to the absence of the items with lower factor loadings in the abbreviated instrument (Table 2), which strengthens the six domains or specific factors (second level), resulting in the weakening of the general factor (first level) until its dissipation. At least 810 studies were conducted in 94 countries using WHODAS 2.0, about 40% in psychiatry, they demonstrated heterogeneous factorial structures, since the number of factors irregularly ranged from 1 to 7 for both the 36-item and the 12-item scale; however none of them evaluated the differences between the two versions regarding the responsiveness to the treatment of psychiatric patients [8,17].…”

“…The WHODAS 2.0 has been validated for Brazil in reproductive-aged women, but not in the male population [8]. Furthermore, people with mental illnesses exhibit unique and pathological latent psychological traits which justify the need for an independent validation process for this special population [9].…”

Functioning and disability of premenopausal women with urinary incontinence: An assessment by using the World Health Organization Disability Assessment Schedule—WHODAS 2.0

“…The WHODAS 2.0 has been used in the evaluation of disability caused by many conditions such as stroke, hand conditions, dementia, maternal complications, and psychiatric disorders . Regarding women's health, publications using ICF as a reference for functioning and disability are concentrated in oncology and maternal areas . Although the ICF was published in 2001, its model and reference are poorly used in UI and publications are concentrated on clinical protocols or on evaluating the quality of life, making the holistic visualization of this health condition difficult.…”

Validation of the WHO Disability Assessment Schedule (WHODAS 2.0) 12-item tool against the 36-item version for measuring functioning and disability associated with pregnancy and history of severe maternal morbidity

“…5 WHODAS 2.0 was translated into, culturally adapted to, and validated for various languages, including Brazilian Portuguese, for a study that implemented it among postpartum women with and without severe maternal morbidity (SMM). 7,8 This retrospective cohort study included 638 women who delivered at a tertiary public hospital in Brazil. Women with SMM showed increased WHODAS-36 scores (functioning impairment) compared with women without SMM.…”
