This study examined the feasibility of using Fitbit Flex activity trackers in a 7-week walking program for 12 individuals with schizophrenia spectrum disorder (SSD). Participants received weekly step count goals and meetings to discuss physical activity. Most participants increased daily step counts, and reported improvements in performance and satisfaction with activities. While no changes in body composition were found, participants identified the Fitbit, step count increases, and praise as motivators for physical activity. Medication side effects were the primary barrier reported. The study demonstrates that wearable trackers may help track and encourage walking in individuals with SSD.
