RESUMO
BACKGROUND: Pectus excavatum (PE) is the most common chest wall deformity. The Nuss Questionnaire modified for Adults (NQmA) is a disease-specific health-related quality of life assessment tool for patients with pectus deformities. The aim of this study is to adapt the NQmA into Turkish. METHODS: Two hundred and sixty-five patients with PE were participated, with an age range of 14 to 29 years. All patients underwent a physical examination and had not undergone corrective surgery. The Turkish version of the NQmA was completed by patients and their parents. RESULTS: The content validity index based on expert opinions was 91% for the patient questionnaire and 96% for the parent questionnaire. The Cronbach's alpha value for the NQmA was found to be 0.805 for the patient questionnaire and 0.800 for the parent questionnaire. Exploratory factor analysis was used to assess construct validity. Two factors explained 51.1% of the total variance in the patient questionnaire (psychosocial: 31.145%, Cronbach's alpha=0.818; physical: 19.955%, Cronbach's alpha=0.862). In the parent questionnaire, two factors explained 51.422% of the total variance (psychosocial: 26.097%, Cronbach's alpha=0.743; physical: 25.325%, Cronbach's alpha=0.827). Construct validity was confirmed by confirmatory factor analysis. CONCLUSION: The Turkish version of the NQmA was found to be valid and reliable for the assessment of quality of life in patients with PE.
RESUMO
BACKGROUND: Pectus excavatum is the most common chest wall deformity. This deformity may cause physical limitations and psychosocial problems. In this study, we aimed to investigate the effect of minimally invasive repair of pectus excavatum on the quality of life. METHODS: This study included 88 patients, aged 18.44 ± 3.93 years (85.2% male), who underwent minimally invasive repair of pectus excavatum; 40.9% had an associated anomaly or disease, and 17.0% had scoliosis. The patients and their parents completed the patient and parent forms of the Nuss questionnaire modified for adults preoperatively and 6 months after the operation. RESULTS: The patients' median Nuss score increased from 31 (interquartile range 31-35) preoperatively to 43 (interquartile range 43-46) at 6 months after the operation (p = 0.000). The parents' preoperative score of 33 (interquartile range 29-36) increased to 38 (interquartile range 34-41; p = 0.000). Improvements in the physical and psychosocial component scores of the Nuss questionnaire were also significant in the patient (p = 0.000, p = 0.000, respectively) and parent forms (p = 0.005, p = 0.000, respectively). CONCLUSIONS: Minimally invasive repair of pectus excavatum significantly improved the physical and psychosocial wellbeing of patients. Longitudinal studies are needed to determine the long-term changes related to quality of life.
