We determined the measurement properties of the Sedentary Time and Activity Reporting Questionnaire (STAR‐Q) designed to estimate past‐month activity energy expenditure (AEE). STAR‐Q validity and reliability were assessed in 102 men and women in Alberta, Canada (2009‐2011), who completed 14‐day doubly‐labeled water protocols, 7‐day activity diaries beginning on Day 15 and the STAR‐Q on Day 14 and again at three and six months. Reliability of the STAR‐Q over the first three months was substantial (ICC = 0.84 and 0.73) for total energy expenditure (TEE) and AEE, respectively. STAR‐Q‐derived TEE and AEE were moderately correlated with DLW estimates (Spearman rho s =0.53 and 0.40 respectively; p<0.001). Body mass index, age, gender and season adjusted‐concordance correlation coefficients (CCC adj ) were 0.24 (95% CI: 0.07, 0.36) and 0.21 (95% CI: 0.11, 0.32) for STAR‐Q versus DLW‐derived TEE and AEE, respectively. Agreement between the diaries and STAR‐Q in MET‐hours/day was strongest for occupational sedentary time (CCC adj =0.76 (95% CI: 0.64, 0.85)) and for strenuous activity (CCC adj =0.64 (95% CI: 0.49, 0.76)). The STAR‐Q demonstrates substantial reliability and reasonable validity for ranking individuals by AEE, occupational sedentary time, and strenuous activity and can be used in epidemiologic studies investigating the health effects of overall energy expenditure and its sub‐dimension components.
