Using Pedometers to Document Physical Activity in Patients with Schizophrenia Spectrum Disorders: A Feasibility Study

Identification of procedures to document physical activity is critical to developing interventions to improve physical health. The purpose of this pilot study was to describe the feasibility and acceptability of pedometers to document physical activity in patients with schizophrenia spectrum disorders (SSDs). Twenty-four outpatients were provided with extended-wear pedometers and instructed to wear them daily for 1 week without altering their usual activities. All participants completed the 1-week data collection period. Twenty-one (87.5%) participants wore their pedometer at least 6 of the 7 days. Difficulties with the pedometers were few and minor. These preliminary findings indicate that a majority of individuals with SSDs are willing to wear pedometers for activity monitoring and can do so with few problems. Possible barriers to the use of extended-wear pedometers in this group include cognitive and memory deficits. Future investigations should test concurrent validity by examining the correlations between pedometer data and self-reported activity level.
