Archives of Internal Medicine, 166, 1092-1097. ___________________________________________________________________________________________________________________ OVERVIEW ___________________________________________________________________________________________________________________ The scale consists of 7 4-point Likert scale items. ___________________________________________________________________________________________________________________ DURATION ___________________________________________________________________________________________________________________ the default set-up of the script takes < 1 min to complete. ___________________________________________________________________________________________________________________ DATA OUTPUT DICTIONARY ___________________________________________________________________________________________________________________ The fields in the data files are: (1) Raw data file: 'gad_7.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: q1-q7: 0 (Not at all) - 3 (Nearly every day) Scale: q8: 0 (Not difficult at all) - 3 (Extremely difficult) 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: 'gad_7_summary.iqdat' (Inquisit Lab: one data file per 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) gad7TotalScore: Total Score (Range: 0 - 21) Spitzer et al (2006, p.1095): "A score of 10 or greater on the GAD-7 represents a reasonable cut point for identifying cases of GAD. Cut points of 5, 10, and 15 might be interpreted as representing mild, moderate, and severe levels of anxiety on the GAD-7 [...]" individual responses: scale: q1-q7: 0 (Not at all) - 3 (Nearly every day) scale: q8: 0 (Not difficult at all) - 3 (Extremely difficult) radioButtons.q1.response to expressions.q8 (*Note: q8 is only presented if participant has indicated any possible response > 0 for any of the seven questions. If all responses = 0, q8 is automatically scored as 0) ___________________________________________________________________________________________________________________ EDITABLE CODE ___________________________________________________________________________________________________________________ check below for (relatively) easily editable parameters, stimuli, instructions etc. Keep in mind that you can use this script as a template and therefore always "mess" with the entire code to further customize your experiment.
