aNot appropriate was coded in all the instances where the participant was not wholeheartedly in favor of that specific timeframe (e.g., the participant’s response suggested the particular timeframe was not appropriate to reflect their physical activity levels and a longer timeframe was needed). bThe 14-day option was presented sequentially to the 7-day option by the moderator during the interview
Note: For the cognitive debriefing part, as not all participants were debriefed on each variable, percentages were calculated out of the total number of participants debriefed for the specific variable. Additionally, participants could choose not to answer questions as they wished
