RESUMO O objetivo deste estudo é validar um instrumento de aferição da funcionalidade segundo a proposta conceitual da Classificação Internacional de Funcionalidade, Incapacidade e Saúde, para uso em pessoas pós-chikungunya. Este é um estudo de validação com indivíduos >17 anos, de ambos os sexos, em atendimento para manejo clínico da chikungunya. A coleta de dados foi realizada por meio de entrevistas coletando informações sobre funcionalidade (WHODAS), qualidade de vida (WHOQOL-bref) e sociodemográficas. A análise estatística usou o coeficiente alfa de Cronbach (consistência interna) e coeficiente de correlação de Spearman (validade convergente), médias e desvios-padrão para a determinação do perfil de qualidade de vida, com nível de significância de 5%. A amostra foi composta por 68 indivíduos. Os valores médios das pontuações dos instrumentos foram: 45,4 (±16,38) para o WHODAS e 12,1 (±2,10) para o WHOQOL-bref. O alfa de Cronbach do valor total foi de α=0,93; todos os domínios do WHODAS apresentaram valores acima de 0,75. O valor total do WHODAS 2.0 apresentou forte correlação com o domínio físico (r=−0,74) e moderada correlação com os domínios psicológico (r=−0,68) e social (r=−0,42) do WHOQOL-bref. Os resultados indicam que o WHODAS 2.0 é um instrumento válido para a mensuração da autopercepção de alteração da funcionalidade em pacientes acometidos pela chikungunya, capaz de fornecer dados que podem ajudar a construir um perfil de impacto da doença no perfil de funcionalidade dessa população.

“…The WHODAS 2.0 has been translated into 47 languages and dialects and is suitable for assessing health status and disability in a variety of settings and populations ( 28 ). Psychometric properties of the WHODAS 2.0 and/or the FUNDES-Adult have been evaluated for a number of clinical conditions, including, but not limited to, the following health conditions: musculoskeletal diseases ( 29 – 32 ), chronic diseases ( 31 , 33 – 36 ), psychiatric conditions ( 29 , 31 , 33 , 37 – 47 ), cancer ( 33 , 48 , 49 ), hearing impairment ( 50 – 52 ), visual impairment ( 50 ), stroke ( 10 , 31 , 33 , 53 – 58 ), Parkinson's disease ( 59 – 62 ), spinal conditions ( 18 , 63 – 65 ), traumatic brain injury ( 63 , 66 , 67 ), multiple sclerosis ( 68 ), persons with disabilities ( 22 , 23 , 35 , 69 , 70 ), older patients discharged from emergency departments ( 71 ) and general population ( 8 , 72 ). Psychometric properties for WHODAS 2.0 36-item and/or FUNDES-Adult have generally been found adequate.…”

“…Psychometric properties for WHODAS 2.0 36-item and/or FUNDES-Adult have generally been found adequate. For example, the internal consistencies at the domain and summary levels of the WHODAS 2.0 ranged from 0.59~0.99 ( 8 ), excellent internal consistency in all languages (alpha > 0.90) ( 28 ), and that of both performance and capability dimensions of the FUNDES-Adult ranged 0.90~0.99 ( 13 , 18 ). The test–retest reliability of the WHOAS 2.0 had an intra-class coefficient of 0.69~0.89 at item level; 0.93~0.96 at domain level; and 0.98 at overall level ( 8 ).…”

“…Each item of the Domain 1 to 6 of the FUNDES-Adult, version 7, has two dimensions—performance and capability—to measure AP in daily life over the previous 30 days ( 13 , 14 , 18 ). The performance refers to the extent of restriction on participation in daily life and the qualifier of performance is described as what an individual does in his or her current environment.…”

To assess activity and participation for adults in Taiwan's Disability Eligibility Determination System (DEDS), we developed a measure, the Functioning Disability Evaluation Scale—Adult version (FUNDES-Adult), based on the 36-item interviewer-administered version of the WHO Disability Assessment Schedule 2.0. The purpose of this study was to examine the factor structures of performance and capability dimensions of the FUNDES-Adult. This study followed a methodology research design to investigate the construct validity of the two dimensions of the FUNDES-Adult. Two samples were randomly stratified from the databank of adults with disabilities to examine structural validity by the exploratory factor analysis (EFA) (n = 8,730, mean age of 52.9 ± 16.81) and the confirmatory factor analysis (CFA) (n = 500, mean age of 54.3 ± 16.81). The results demonstrated that the EFA yielded 5-factor structures for both performance dimension (73.5% variance explained) and capability dimension (75.9% variance explained). The CFA indicated that the second-order factor structures of both dimensions were more parsimonious with adequate fit indices (GFI, NFI, CFI, and TLI ≥ 0.95, RMSEA < 0.09). The results of this study provide evidence that the FUNDES-Adult has acceptable structural validity for use in Taiwan's DEDS. Utility of the FUNDES-Adult in rehabilitation, employment, welfare, and long-term care services needs further study.

“…IRT, such as Rasch analysis, allows analyses that also provide information about rating scales, items and item bias between subgroups [ 12 ]. Item and individual characteristics of the 36-item WHODAS 2.0 have been evaluated using Rasch analysis in international populations with spinal cord injury [ 13 ], multiple sclerosis [ 14 ], stroke [ 15 ] and osteoarthritis [ 16 ]. Some studies have examined the self-administrated version [ 14 , 17 ], but the majority explored the interviewer-administrated version, and only two of the studies involved patients with mental disorders, namely, schizophrenia and drug addiction with comorbid mental disorders [ 18 , 19 ].…”

Background The World Health Organization Disability Assessment Schedule 2.0 (WHODAS 2.0) is a generic instrument for the assessment of functioning in six domains, resulting in a total health-related disability score. The aim of this study was to investigate the psychometric properties of the Swedish-language version of the self-rated 36-item version in psychiatric outpatients with various common psychiatric diagnoses using Rasch analysis. A secondary aim was to explore the correlation between two methods of calculating overall scores to guide clinical practice: the WHODAS simple (summative) model and the WHODAS complex (weighted) model. Methods Cross-sectional data from 780 Swedish patients with various mental disorders were evaluated by Rasch analysis according to the partial credit model. Bivariate Pearson correlations between the two methods of calculating overall scores were explored. Results Of the 36 items, 97% (35 items) were within the recommended range of infit mean square; only item D4.5 (Sexual activities) indicated misfit (infit mean square 1.54 logits). Rating scale analysis showed a short distance between severity levels and disordered thresholds. The two methods of calculating overall scores were highly correlated (0.89–0.99). Conclusions The self-administered WHODAS 2.0 fulfilled several aspects of validity according to Rasch analysis and has the potential to be a useful tool for the assessment of functioning in psychiatric outpatients. The internal structure of the instrument was satisfactorily valid and reliable at the level of the total score but demonstrated problems at the domain level. We suggest rephrasing the item Sexual activities and revising the rating scale categories. The WHODAS simple model is easier to use in clinical practice and our results indicate that it can differentiate function among patients with moderate psychiatric disability, whereas Rasch scaled scores are psychometrically more precise even at low disability levels. Further investigations of different scoring models are warranted.
