Corrigendum to “A randomized trial of a motivational interviewing intervention to increase lifestyle physical activity and improve self-reported function in adults with arthritis” [Seminars in Arthritis and Rheumatism 47(2018): 732–740, (S0049017217303621), (10.1016/j.semarthrit.2017.10.003)]

The authors regret that an error was made in the Methods section of the manuscript pertaining to the definition of non-sedentary activity minutes. In the manuscript we stated, “Physical activity measures were summarized as average daily minutes of non-sedentary activity (counts of ≥100 per minute that includes light, moderate, and vigorous intensity activity).” The actual definition that we used was counts of >0 per minute. The reason for the error was the change in practice of the physical activity measurement community to move from the >0 counts/minute threshold to the >100 counts/minute threshold after the study's data had been collected. Tables 1, 2 and 3 have been redone below indicating "Average daily activity minutes" using both thresholds. The overall conclusions that the intervention had no effect on physical activity are unchanged. The authors would like to apologise for any inconvenience caused.
