Abstract	EDUARDO, A.H.A. Psychometric properties of the Brazilian version of the questionnaire Quality of recovery 40 item. 2015 196f. Thesis (Doctoral) – University of São Paulo at Ribeirão Preto College of Nursing, Ribeirão Preto, 2015. Postoperative recovery is a complex event that comprehends the resumption of daily activities and improvement of the physical, emotional and psychological states of the patients, which were altered as consequences of the surgical treatment. However, the determination of the moment in which the surgical recovery has occurred requires rigorous medical supervision of the patients. The Quality of recovery -40item (QoR-40) questionnaire enables an evaluation of the postoperative recovery in physical, emotional, social and psychological dimensions. Therefore, it can be an important tool for such supervision. The Qor-40 has 40 items with Likert scale answers and its total score varies from 40 to 200, in which the results are increased in accordance with the quality of postoperative recovery. It's a methodological study that aims to validate the Brazilian version of the QoR-40 questionnaire to be used with patients who have undergone radical prostatectomy. The questionnaire was answered by a sampling of 200 radical prostatectomized patients in four distinct moments: preand postoperative, first and second follow-up appointments. A semantic analysis of the questionnaire's items was performed, in a sampling independent of the validation sampling, to investigate the comprehension and relevance of each item. For the convergent construct validity, an investigation was performed, concerning the Pearson correlation between the QoR-40 measure and the measures of the constructs related to the domains of the quality of life questionnaire (SF-36v2) as well as the measure of the visual analogue scale for postoperative recovery (VAS postoperative recovery). The discriminant validity was investigated by means of known groups, through the Mann-Whitney test, considering the QoR-40 measure in the groups of patients with a nursing diagnosis of Retarded postoperative recovery, with urinary incontinence and erectile dysfunction. The reliability was investigated by means of the internal consistency, considering Cronbach's alpha and inter-item/item-total correlations. Responsivity was investigated by means of linear regression with mixed effects and analysis of the standardized response mean (SRM). The semantic analysis, performed with 24 people, has resulted in discreet alterations in the wording of items 6, 19 and 23 in a manner that has accomplished their understanding, as identified in the pretest. In the convergent construct validity, the correlations between the measures of the QoR-40 and the measures of SF-36v2 and VAS postoperative recovery domains were predominantly moderate (r=0.18 to 0.89); the discriminant construct validity has presented differences between patients with a nursing diagnosis of Retarded postoperative recovery, with urinary incontinence (p<0.01). The reliability, by means of internal consistency, has obtained satisfactory Conbach's alpha values (0.75 to 0.86) and predominantly moderate inter-item and item-total correlations (r= 0.02 to 0.64). The responsivity was adequate, with a mean of difference of the statistically significant measures (p<0.01) in the course of time and with SRM varying from 0.03 to 1.11. As a result, it can be concluded that the QoR-40 has adequate validity, reliability and responsivity, taking into consideration the data obtained in the study performed with patients who have undergone radical prostatectomy.
