Participant training is very important to the success of EMA data collection. Participant training was conducted by the research team with groups of 9-12 participants, during 90 minutes sessions conducted at various times throughout the day to accommodate typical work day schedules. Training materials included a review of research practices, university and organizational policies, and the study informed consent. Each person received an instruction booklet that included step-by-step instructions for responding to prompts and entering data including an extensive review of how the EMA devices operate.

Data was collected in 6 groups between March of 2013 and October 2013.
