Tradução para a língua portuguesa e análise das propriedades psicométricas do instrumento Patient Generated Index (PGI) para pacientes com doença pulmonar obstrutiva crônica: avaliação individualizada de qualidade de vida / Portuguese translation and validation of the Patient Generated Index (PGI) instrument for patients with Chronic Obstructive Pulmonary Disease: individualized quality of life assessment

RESUMO Objetivo Traduzir, adaptar e validar o Patient Generated Index (PGI) para brasileiros com doença pulmonar obstrutiva crônica (DPOC). Métodos 50 voluntários com DPOC, em sua maioria homens (74%), com 73,1 ± 8,9 anos de idade, VEF1 de 52,3 ± 14,5% do previsto e VEF1/CVF de 56,2 ± 8,6% do previsto, responderam ao PGI e ao Saint George Respiratory Questionnaire (SGRQ) e realizaram teste Glittre Activities of Daily Living (Glittre ADL). Após o período de 7-14 dias, o PGI foi novamente aplicado para análise da confiabilidade relativa e absoluta. Resultados A tradução ocorreu sem alterações no questionário. A pontuação obtida no PGI apontou fraca correlação com a pontuação total do SGRQ (r = −0,44; p < 0,001) e com o domínio impacto (r = −0,40; p < 0,05), moderada correlação com o domínio sintomas do SGRQ (r = −0,55; p < 0,001) e fraca correlação com o domínio atividades (r = −0,31; p < 0,05). Foram observadas fraca correlação entre o PGI e o Glittre ADL (r = −0,30; p < 0,05) e alta confiabilidade entre as medidas do PGI (CCIr = 0,94). Conclusão Este estudo mostra que a versão brasileira do PGI é um instrumento confiável e válido para medir a qualidade de vida relacionada à saúde em pacientes com DPOC. Trata-se de uma nova forma individualizada de avaliação de qualidade de vida centrada no paciente com DPOC.

ABSTRACT Objective To translate, adapt and validate the Patient Generated Index (PGI) for Brazilians with chronic obstructive pulmonary disease (COPD). Methods 50 volunteers with COPD, mostly men (74%), with 73.1 ± 8.9 years of age, FEV1 of 52.3 ± 14.5% of predicted and FEV1 / FVC of 56.2 ± 8.6% of predicted responded to PGI, to the Saint George Respiratory Questionnaire (SGRQ) and to perform Glittre Activities of Daily Living test (Glittre ADL). After 1-2 weeks, PGI was again applied for the analysis of relative and absolute reliability. Results The translation occurred without changes in the questionnaire. The score obtained in PGI had weak correlation with the SGRQ total score (r = -0.44, p <0.001) and with the impact domain (r = -0.40, p <0.05), presented a moderate correlation with the symptoms domain of the SGRQ (r = -0.55, p <0.001) and weak correlation with the activity domain (r = -0.31, p <0.05). A weak correlation was observed between PGI and Glittre ADL (r = -0.30; p <0.05). It was observed high reliability among the measures of PGI (ICCr = 0.94). Conclusion This study shows that the Brazilian version of PGI is a reliable and valid instrument to measure health-related quality of life (HRQL) in patients with COPD. It is a new and individualized form of evaluation of COPD patient-centered quality of life.

Educational program for coronary artery disease patients: results after one year / Programa educativo para pacientes con enfermedad arterial coronaria: resultados después de un año / Programa educativo para pacientes com doença arterial coronariana: resultados após um ano

ASTRACT Objective: To evaluate the long-term results of an educational program compared to usual care. Method: A longitudinal study in which 56 participants from a previous study (randomized controlled clinical trial) were evaluated twelve months after the percutaneous coronary intervention (PCI). Health-related quality of life (HRQoL) was assessed by the Medical Outcomes Study: 36-item Short Form (SF-36), and anxiety and depression symptoms were assessed by the Hospital Anxiety and Depression Scale (HADS). A repeated measures analysis of variance was performed (significance level 0.05). Results: Participants in the educational program showed improvement of HRQoL in the Role-Emotional domain, while those in the usual care did not present changes (p=0.05). Both groups showed improvement in the Role-Physical (p = 0.001) and Bodily Pain (p=0.01) domains over time. There were no differences in the symptoms of anxiety and depression. Conclusion: One year after the PCI, there were significant differences between groups only for the Role-Emotional domain of the SF-36.

RESUMEN Objetivo: Evaluar resultados a largo plazo de un programa educativo comparado con el cuidado usual. Método: Estudio longitudinal con 56 participantes de un estudio previo (ensayo clínico controlado y aleatorizado), que fueron evaluados 12 meses después de la intervención coronaria percutánea (ICP). La calidad de vida relacionada con la salud (CVRS) fue evaluada por el Cuestionario de Salud SF-36 (36-Item Short Form) y los síntomas de ansiedad y depresión por la Escala de Ansiedad y Depresión Hospitalaria (sigla en inglés: HADS). Se realizó un análisis de varianza de medidas repetidas (nivel de significancia 0,05). Resultados: Los participantes del programa educativo presentaron mejoría de la CVRS en el dominio Rol Emocional, mientras que los participantes del cuidado usual no presentaron alteración (p=0,05). Con el tiempo, ambos grupos presentaron mejoría en los dominios Rol Físico (p=0,001) y Dolor Corporal (p=0,01). No hubo diferencias en los síntomas de ansiedad y depresión. Conclusión: Un año después de la ICP, hubo diferencias significativas entre los grupos sólo para el dominio Rol Emocional del SF-36.

RESUMO Objetivo: Avaliar resultados em longo prazo de um programa educativo comparado com o cuidado usual. Método: Estudo longitudinal com 56 participantes de um estudo prévio (ensaio clínico controlado e aleatorizado), que foram avaliados doze meses após intervenção coronária percutânea (ICP). A qualidade de vida relacionada à saúde (QVRS) foi avaliada pelo Medical Outcomes Study: 36-Item Short Form (SF-36) e os sintomas de ansiedade e depressão pela Hospital Anxiety and Depression Scale (HADS). Foi realizada análise de variância de medidas repetidas (nível de significância 0,05). Resultados: Os participantes do programa educativo apresentaram melhora da QVRS, no domínio Aspectos Emocionais, enquanto aqueles do cuidado usual não apresentaram alteração (p=0,05). Com o tempo, ambos os grupos apresentaram melhora nos domínios Aspectos Físicos (p=0,001) e Dor (p=0,01). Não houve diferenças nos sintomas de ansiedade e depressão. Conclusão: Um ano após a ICP, houve diferenças significativas entre os grupos apenas para o domínio Aspectos Emocionais do SF-36.

Evaluation of the Family Impact Scale for use in Brazil

OBJECTIVES: The objectives of this study were to assess the validity and reliability of the Family Impact Scale (FIS) applied in Brazilian parents after translations and cultural adaptations to Brazilian Portuguese language and to evaluate the nature and extent to which the family functioning is compromised by the child oral conditions. MATERIAL AND METHODS: Parents were recruited from general populations for pre-testing (n=20), validity (n=210) and test-retest reliability (n=20) studies. The children were examined for dental caries, gingivitis, fluorosis and malocclusion. RESULTS: The FIS discriminated among the categories of malocclusion and showed good construct validity. The Cronbach's alpha and intraclass correlation coefficients were 0.87 and 0.90, respectively. Almost 20 percent of the informants reported some family impact `sometimes' or `often/everyday' from the child's oral condition. Impact on FIS domains of this frequency ranged from 13.8 percent for financial difficulties to 24.4 percent for parental or family activities. CONCLUSIONS: The Brazilian Portuguese version of FIS is valid and reliable. The results suggest that child oral conditions have a negative impact on the family. Further research is required, as these findings were based on cross-sectional study and convenience samples.
