(1984). A new rating scale for Alzheimer’s disease. American Journal of Psychiatry, 141: 1356-1364. order of Noncognitive items from: (b) Mohs RC & Cohen L (1988). Alzheimer’s Disease Assessment Scale (ADAS). Psychopharmacology Bulletin, 24: 627-628. Word items (if not specified in Rosen et al, 1984) and order of Cognitive Behavior questions can be taken from: (c) Schultz, R.R, Siviero, M.O, & Bertolucci, P.H.F. (2001). The cognitive subscale of the “Alzheimer’s Disease Assessment Scale” in a Brazilian sample. Brazilian Journal of Medical and Biological Research, 34, 1295-1302. Notes: (1) The main purpose of this script is to help keep track of scoring. For many of these tasks, the evaluation of the patient's responses has to be done by an experienced examiner. (2) The examiner -not the patient- fills out the ADAS based on evaluation of patient (4) Test administration guidelines are provided in Rosen et al (1984). (5) Examiner has options to choose to run the cognitive and noncognitive assessment or only one of the two (-> Editable parameter) (6) Rosen et al (1984) describe many of the scoring scales on a 1(mild)-5(severe) scale without a 0 category (= no impairment). Millisecond Software added the 0-categories to the scales (see also Mohs & Cohen, 1988). ___________________________________________________________________________________________________________________ DATA FILE INFORMATION ___________________________________________________________________________________________________________________ The default data stored in the data files are: (1) Raw data file: 'adas.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: 'adas_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) ADAS_totalscore: sum of Cogn_Score48, Memory_Score22, NonCogn_Score50 cogn_score70: sum of all cognitive behavior assessment items (Max: 70) cogn_score48: sum of Cognitive Behavior Assessment scores (minus Memory Scores) (Max: 48) memory_score22: sum of Recall and Recognition Scores (Max: 22) noncogn_score50: sum of NonCognitive Behavior Assessment scores (Max: 50) recall - recognition: assigned scores for Cognitive Assessment Scores tearful- appetite: assigned scores for Non-Cognitive Assessment 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. The parameters you can change are: /skipCognAssessment: true: skips Cognitive Behavior Assessment Items false: runs Cognitive Behavior Assessment Items (default) /NonskipCognAssessment: true: skips NonCognitive Behavior Assessment Items false: runs NonCognitive Behavior Assessment Items (default)
