Questionario per la Valutazione della Qualità della Vita nei soggetti sani (VQV-ss): Elaborazione di un nuovo strumento per l'assessment della Qualità della Vita nella popolazione generale
Objective: The aim of our study was the elaboration of a new questionnaire for the assessment of Quality of Life (QoL) in subjects not affected by any General Medical Condition or psychiatric disorder. Methods: We recruited 200 healthy subjects from the general population; they rated themselves on the Quality of Life Enjoyment and Satisfaction Questionnaire (Q-LES-Q) and the Questionnaire for the Assessment of Quality of Life in Healthy Subjects (VQV-ss), that we elaborated. Results: The VQV-ss showed a good inner consistency (0,8775). The Concurrent validity was estimated by means of the correlations between the VQV-ss and the Q-LES-Q total score (r = 0,566; p < 0,001). The correlation between the item 71 score and the total one of the VQV-ss, representative of the total subject's QoL (r = 0,674; p = 0,01), witnessed the overall sensitivity and specificity of the VQV-ss. Factorial analysis of the VQV-ss identified 6 main factors, able to explain, altogether, the 37,55% of the total variance. Conclusions: The VQV-ss appears to be sufficiently reliable and valid, since shows a good inner consistency and the scores obtained with this instrument correlate in significantly with those of the Q-LES-Q, a validated and widely used instrument
