DIAGNOSTIC VALIDITY OF SCREENING QUESTIONNAIRE AMERICAN COLLEGE OF SPORTS MEDICINE/AMERICAN HEART ASSOCIATION

VALIDADE DIAGNÓSTICA DO QUESTIONÁRIO DE TRIAGEM DO AMERICAN COLLEGE OF SPORTS MEDICINE/AMERICAN HEART ASSOCIATION

ABSTRACT

The prevention of cardiovascular events is one of the main objectives of a preexercise screening questionnaire. The aim of this study was to evaluate the diagnostic validity of ACSM/AHA questionnaire (AAPQ), through the Sensitivity (Se), Specificity (Sp) and AUC (area under the curve). The study included 69 subjects (40-81 years). Comparisons between sex and age categories were performed. There was no significant difference. However, the variation in positive responses seemed to increase in percentage terms, especially after 60 years (from 78.6% to 100%). The AAPQ Se values were high (88.2%) suggesting that the majority of individuals in whom the instrument was positive showed some contraindication. However, the Sp value was only 13.5%, indicating that the questionnaire was not able to identify those with no contra indication to start an exercise program. Thus, the instrument would have a low diagnostic capacity (AUC = 0.51). The results suggest that the questionnaire presents a low capacity to identify individuals suitable for inclusion in an exercise program.
