BACKGROUND: Recently a new version of International Physical Activity Questionnaire was performed for adolescent (IPAQ-A), but an Italian version lacks yet. The aim of the study is to examine the test-retest reliability of an Italian version of short IPAQ-A.
METHODS: A sample of 10-18-year-old children and adolescents was considered. The IPAQ questionnaires were administered twice, the second time two days after the first administration. Test-retest reliability and internal reliability of the questionnaire were determined using ICC and Cronbach's alpha, respectively.
RESULTS: 277 questionnaires were collected. The response rate was 97% but 57% of the sample completed all the items in the questionnaire. 43% of the students have not completed all the items and its age distribution shown that 93.5% was in 10-13 years old. Overall internal reliability (Cronbach's alpha=0.84) and test-retest reliability for 16 out of 23 items (ICC>0.70) were high.
CONCLUSIONS: The study presents missing and unreasonably values. However the study underlines pros and cons of the IPAQ-A: high reliability and feasibility to measure the physical activity especially in adolescent aged 14-18 years; the IPAQ-A needs of attention and it hasn't to leave it to the self-compilation but give support especially in the youngers.
