Abstract
The study’s purpose was to examine the measurement domain of confidence itemsused in physical activity research. We hypothesized that confidence items, includinga phrase to hold motivation constant, would differ from standard confidence items.Participants (N=248 students) completed confidence items, a thought-listing pro-cedure, and a 2-week self-report of physical activity. Results showed that confidenceitems with motivation held constant loaded exclusively on one factor, but standardconfidence items were factor complex with intention. Correlations with physicalactivity intention and behavior were larger for confidence items than confidenceitems with motivation held constant. Finally, the thought-listing procedure identifiedthat 3 of the 7 reasons for answering confidence items were outside the intendedmeasurement domain of self-efficacy.
