III, Monk, T.H., Berman, S.R. & Kupfer, D.J. (1989). The Pittsburgh Sleep Quality Index: a new instrument for psychiatric practice and research. Psychiatry Research, 28, 193-213. ___________________________________________________________________________________________________________________ OVERVIEW ___________________________________________________________________________________________________________________ The PQSI poses 19 questions to participants (+ 5 optional ones to their partner at the very end). The 19 questions assess 7 different components (or subscales): Component1: Subjective Sleep Quality Component2: Sleep Latency Component3: Sleep Duration Component4: Habitual Sleep Efficiency Component5: Sleep Disturbances Component6: Use of Sleep Medication Component7: Daytime Dysfunction Each of those components are scored on a scale from 0-3. A Global PQSI Score is the sum of all those component scores (range: 0-21). ___________________________________________________________________________________________________________________ DURATION ___________________________________________________________________________________________________________________ the default set-up of the script takes appr. 2 minutes to complete ___________________________________________________________________________________________________________________ DATA OUTPUT DICTIONARY ___________________________________________________________________________________________________________________ The fields in the data files are: (1) Raw data file: 'psqi.iqdat' (1) Raw data file: 'psqi.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 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: 'psqi_bulgarian_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) Summarydata for each participant: file saves the scores for the subscales and totalscore textbox.age.response: the reported age of the participant skippartnerQuestions: 1 = partner questions were omitted; 0 = partner questions were run included to check accuracy of scoring: bedDuration: the calculated time a participant spent in bed (though not necessarily sleeping) q5j: contains the stored response for question 5j that is used to evaluate the response to calculate the component 5 score. The defaultresponse is "Not during the past week" unless participant provided another sleep disturbing reason AND selected a different response other than the defaultresponse. The value recorded under values.q5j MAY differ from the response recorded under radioButtons.q5j2.response (see raw data file). This happens IF no other sleep disturbing reason was provided by participant but yet the defaultresponse for radioButtons.q5j2 was changed. In this case, values.q5j still stores the defaultresponse which will evaluate to 0. => Without another sleep disturbing reason provided, the response will always be scored as 0 subcomponent scores on a scale from 0 (least problematic) to 3 (most problematic) ///Component 1 Score: comp1SubjectiveSleepQuality: component1 score ///Component 2 Score with subscores: comp2SleepLatencyA: comp2SleepLatencyB: comp2SleepLatency: ///Component 3 Score: !Note: the scoring guidelines in the article were a bit fuzzy in regard to the boundaries in this script: anything 7 or greater gets assigned a 0 comp3SleepDuration: ///Component 4 Score: !Note: the scoring guidelines in the article were a bit fuzzy in regard to the boundaries in this script: anything 85 or greater gets assigned a 0 comp4HabitSleepEffic: ///Component 5 Score with subscores: !Note: question 5j is optional as it requires participant to think of another reason that could potentially disturb their sleep. Since not all participants might think of something, this question was left optional (and the default response is "not during the past week") => the guidelines still include question 5j comp5SleepDisturb5b- comp5_sleepdisturb_5j* comp5SleepDisturbSum: comp5SleepDisturb: *Note: /comp5_sleepdisturb_5j uses values.q5j instead of radioButtons.q5j2.response ///Component 6 Score: comp6SleepMedic: ///Component 7 Score with subscores: comp7DayTimeDysfuncA: comp7DayTimeDysfuncB: comp7DayTimeDysfunc: ///Global Score: globalPSQIScoreR: sum of all sub component scores ___________________________________________________________________________________________________________________ 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.
