(2001). Validation of the Insomnia Severity Index as a clinical outcome measure for insomnia research. Sleep Medicine, 2, 297-307. ___________________________________________________________________________________________________________________ OVERVIEW ___________________________________________________________________________________________________________________ This script offers the 7 questions of the Insomnia Severity Index on a single surveypage. A demographic surveypage at the beginning (by default: not run) as well as a feedback page at the end (by default: run) are optional and controlled via Editable Parameters. ___________________________________________________________________________________________________________________ DURATION ___________________________________________________________________________________________________________________ the default set-up of the script takes appr. 1 minute to complete ___________________________________________________________________________________________________________________ DATA FILE INFORMATION ___________________________________________________________________________________________________________________ The default data stored in the data files are: (1) Raw data file: 'insomniaseverityindex.iqdat' (a separate file for each participant) 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 - 4 (anchors depend on question) no automatically reversed scored questions 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: 'insomniaseverityindex_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) textbox.name.response/textbox.age.response/dropdown.gender.response: Name/Age/Gender-if collected isi_totalscore: the participant's total ISI score ___________________________________________________________________________________________________________________ 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. The parameters you can change are: /skipdemographics: false = script does collect demographic data true = script does NOT collect demographic data (default) /skipfeedback: false = script does provide feedback to participants (default) true = script does NOT provide feedback to participants Note: to customize feedback go to EDITABLE CODE -> Editable Stimuli
