Cultural Validation of the Transplanted Organ Questionnaire (TOQ) for the Brazilian Population.

BACKGROUND AND RATIONALE: The Transplanted Organ Questionnaire (TOQ), developed in France, is a disease-targeted instrument designed to evaluate what the transplanted organ represents to the recipient in patients who have undergone liver transplantation. The present study sought to validate a version of the TOQ for use in the Brazilian population. Translation and cross-cultural adaptation were carried out in accordance with international standard practices. Convergent validity was measured by correlations between TOQ domains and the Beck Depression Inventory (BDI), while reliability was assessed by measurement of internal consistency (Cronbach's alpha coefficient), reproducibility (intraclass correlation coefficient), sensitivity to change (effect size), and floor and ceiling effects. RESULTS: The study sample comprised 122 liver transplant recipients, with a mean age of 56.7 ± 9.9 years, treated at the outpatient clinic of a tertiary hospital in Southern Brazil. The sample was largely male (57.4%), and the predominant indication for liver transplant was hepatocellular carcinoma (34.4%). The mean total TOQ score was 32.9 ± 18.0. Cronbach's alpha for the total score was 0.89 (95%CI 0.86-0.92). Correlations between TOQ and BDI domains were acceptable, with the rejection domain correlating most strongly (r = 0.37; p ≤ 0.001). In conclusion, the Brazilian Portuguese version of the TOQ exhibited good psychometric performance, suggesting that it can be a useful tool in the Brazilian cultural context.

Cultural validation of the post-Liver transplant quality of life (pLTQ) questionnaire for the Brazilian population.

BACKGROUND AND RATIONALE: The post-Liver Transplant Quality of Life (pLTQ) questionnaire, developed in the United States, is a disease-targeted instrument designed to evaluate health-related quality of life (HRQoL) in liver transplant recipients. Our study sought to validate a version of the pLTQ for use in the Brazilian population. Translation and cross-cultural adaptation were carried out in accordance with international standard practices for questionnaire validation. Validity was measured by means of convergent validity (correlations between pLTQ domains and WHOQOL-Bref domains). Reliability was assessed by measurement of internal consistency (Cronbach's alpha coefficient), reproducibility (intraclass correlation coefficient), sensitivity to change (effect size), and floor and ceiling effects. RESULTS: The study sample comprised 160 liver transplant recipients, with a mean age of 56.9 ± 10.4 years, treated at a tertiary hospital in Southern Brazil. The sample was largely male (62.5%), and the predominant indication for liver transplant was hepatocellular carcinoma (49.4%). Only two questionnaire items were modified during the translation and cross-cultural validation stage. The mean total pLTQ score was 5.58 ± 0.9, with < 20% floor/ceiling effect. Correlations between pLTQ and WHOQOL-Bref domains were acceptable (r = 0.37-0.40). For similar dimensions, the correlations between WHOQOL-Bref and pLTQ were statistically significant (p ≤ 0.001). Cronbach's alpha for the total score was 0.91 (95% CI 0.89-0.93), with a range of 0.51 to 0.77 across domains. Reproducibility was 0.90, and sensitivity to change was 0.84. CONCLUSION: In conclusion, the Brazilian Portuguese versión of the pLTQ exhibited good psychometric performance, suggesting that it can be a useful tool in the Brazilian cultural context.

Evaluation of body image and self-concept and their correlation with depressive symptoms in Parkinson's disease.

OBJECTIVE: To identify characteristics of body image and self-concept in individuals over fifty years of age with Parkinson's disease (PD). The secondary objectives are to analyze whether body image and self-concept are influenced by the severity of PD and to verify if there is correlation between depression, self-concept and body image in cases of PD. METHOD: Participating in the study were 48 individuals, being 26 with PD and 22 Controls. The instruments used were: The Mini Exam of Mental State, The My Body Image Test, The Factorial Self-concept Test, The Beck Depression Inventory, the motor section of The Unified Parkinson's Disease Rating Scale and The Modified Hoehn and Yahr Scale. RESULTS: In PD the perception of body image and self-concept demonstrated significantly reduced values p<0.001 and p=0.012 respectively, and the presence of depression symptomatology was significantly more (p=0.002). CONCLUSION: Individuals with PD present alteration of body image and self-concept and also present lower personal confidence and lower social receptivity, correlated with depressive symptoms.

OBJETIVO: Identificar características de imagem corporal e autoconceito em indivíduos com doença de Parkinson (DP) acima de cinqüenta anos de idade. Os objetivos secundários são analisar se a imagem corporal e o autoconceito são influenciados pela gravidade da DP e, verificar se existe correlação entre depressão, autoconceito e imagem corporal na DP. MÉTODO: Participaram do estudo 48 indivíduos, sendo 26 com DP e 22 Controles. Os instrumentos utilizados foram: Mini-Exame do Estado Mental, Teste A Minha Imagem Corporal, Escala Fatorial de Autoconceito, Inventário de Depressão de Beck, Unified Parkinson's Disease Rating Scale parte motora e Hoehn e Yahr Modificada. RESULTADOS: Na DP a percepção da imagem corporal e do autoconceito, demonstraram valores reduzidos significativamente (p<0.001 e p=0.012) respectivamente, e a sintomatologia depressiva apresentou-se significativamente maior (p=0.002). CONCLUSÃO: Indivíduos com DP apresentam alteração da imagem corporal e do autoconceito, apresentaram também menos confiança pessoal e menor receptividade social correlacionados com sintomas depressivos.
