a b s t r a c tThis research provides a critical consideration of the outcome measures used to assess physical activity in individuals with severe mental illness. A narrative synthesis was utilised to provide a simple juxtapose of the current research. A sensitive topic-based search strategy was conducted in order to identify studies that met the eligibility criteria. Fifty two studies met the inclusion criteria and 5 were identified specially as validation studies. The current research identified several methodological shortcomings. The justification and choice of outcome measure used is often weak and only five studies have validated a specific outcome measure of physical activity. Within these validation studies, the validation process often lacked a consideration of agreement between measures. Accelerometers have been most frequently used as a criterion measure, notably the RT3 tri-axial accelerometer. Objective based measures may be best placed to consider physical activity levels, although, methodological considerations for the utilization of such tools is required. Self-report questionnaires have benefits for use in this population but require further validation. Researchers and clinicians need to carefully consider what outcome measure they are using and be aware of the development, scope and purpose of that measure.Crown

“…In patients with multi-episode or chronic schizophrenia, physical activity is significantly lower than in the background population (8,9). Low physical activity is associated with more frequent occurrence of T2D (10), more metabolic disturbances, reduced global functioning, and lower quality-of-life (9,(11)(12)(13).…”

“…The RT3 accelerometer, the IDEEA, and the SWA are three accelerometers that are frequently used to measure PA. 20,[29][30][31][32][33][34][35][36][37][38][39] The RT3 measures the magnitude of acceleration in three dimensions to provide vector data in 'counts'. Counts are converted into kilocalories (kcal) with the use of algorithms based on the wearer's characteristics.…”

Background: Recent research has indicated that energy expenditure (EE) is predictive of health related outcomes. Valid, reliable and feasible measures of EE are required to further investigate this relationship and to monitor adherence to activity guidelines. Objective: To assess the ability of activity monitors to measure EE in apparently healthy adults and children.Major findings: Three monitors met the inclusion criteria for this review: the RT3, the IDEEA, and the Sensewear Pro Armband (SWA). Thirty-three studies reported on the validity and reliability of these monitors. Fifteen studies reported on the feasibility of the monitors. The ability of the monitors to assess EE varied across activity types. All monitors underestimated the energy cost of free-living activities. The estimation of total energy expenditure from all three monitors disagreed considerably with a criterion measure of EE. Conclusion: Of these monitors, the SWA is the most studied activity monitor in adults and children. However, until a standardized methodology is used in validation studies, it is difficult to recommend the use of one monitor above others. Further research is required into the comparative validity, the reliability and the feasibility of these monitors to aid monitor selection.
