The feasibility and acceptability of using EMA and physiological data to measure day-to-day occupational stress, musculoskeletal pain and mental health

Adherence to the study protocol was excellent. Participants wore the wristband for a mean of 9.7 days. Participants completed a mean of 24.5 EMAs (out of 30). Semi-structured interviews with participants revealed that a small number of participants had difficulties uploading data from the wristband. The timing of EMAs was challenging for some participants, resulting in missed EMAs, raising questions about whether EMA frequency and timing could be changed to improve adherence. Some EMA items were difficult to answer due to the nature of participants' roles and the work undertaken. Overall, the protocol was feasible and acceptable but highlighted future potential changes including using a different physiological data collection tool, reducing the number of EMAs, adjusting EMA timings, and reviewing EMA items.
