Abstract:

The study aimed to evaluate the content validity and reliability of an instrument to evaluate the university food environment. A checklist was developed for the assessment of establishments that sold food and beverages in the university environment. The content validation encompassed the development of the instrument, its evaluation by expert and performing the pre-test. Reliability was evaluated in a convenience sample (n = 64) of establishments distributed in seven campuses of three public universities and was carried out using interobserver (IO) and test-retest (TR) tests. Categorical and countable variables were analyzed by means of calculation of percentage agreement (PA) and of kappa coefficient (k) and prevalence-adjusted and bias adjusted kappa (PABAK) and continuous variables were analyzed by the Intraclass Correlation Coefficient (ICC). The checklist consisted of 204 items distributed in seven domains. The instrument's performance was considered excellent or very good for 91.3% (PA) of the items when evaluated. In IO 68.3% (k) and 96.5% (PABAK) had excellent, very good or good agreement, while in TR 65% had excellent agreement for k and 96.5% for ka. The instrument showed satisfactory content validity and reliability for characterizing the food environment in Brazilian universities.
