The scale provides Self-efficacy scores on three scales: Healthful Eating Self-efficacy (HESE) (q1-q4) Physical Activity Self-efficacy (PASE) (q5-q8) Weight Loss Self-efficacy (WLSE) (q9-q12) ___________________________________________________________________________________________________________________ DURATION ___________________________________________________________________________________________________________________ the default set-up of the script takes appr. 2 minute to complete __________________________________________________________________________________________________________________ DATA OUTPUT DICTIONARY ___________________________________________________________________________________________________________________ The fields in the data files are: (1) Raw data file: 'wlse.iqdat' date, time: date and time script was run with the current group/subjectnumber subject, group, session: with the current subject/groupnumber/session id build: the Inquisit build q*_response: response given (in assigned values) Scale: 0% (not confident at all) - 100% (completely confident) q*_latency: how much time (in ms) the participant spent on the surveyPage with this particular question (the last time this particular surveyPage was visited) (2) Summary data file: 'wlse_summary*.iqdat' (a separate file for each participant) inquisit.version: Inquisit version run computer.platform: the platform the script was run on (win/mac/ios/android) startDate: date script was run startTime: time script was started subjectId: assigned subject id number groupId: assigned group id number sessionId: assigned session id number elapsedTime: time it took to run script (in ms); measured from onset to offset of script completed: 0 = script was not completed (prematurely aborted); 1 = script was completed (all conditions run) hese: Healthful Eating Self-Efficacy, measured as mean of q1,q2,q3,q4 response pase: Physical Activity Self-Efficacy, measured as mean of q5,q6,q7,q8 response wlse: Weight Loss Self-Efficacy, measured as average of q9,q10,q11,q12 response + individual responses
