(2011). The RT-18: a new screening tool to assess young adult risk-taking behavior. International Journal of General Medicine, 4, 575–584. ___________________________________________________________________________________________________________________ OVERVIEW ___________________________________________________________________________________________________________________ 18 yes/no questions about risk taking behavior. ___________________________________________________________________________________________________________________ DURATION ___________________________________________________________________________________________________________________ the default set-up of the script takes appr. 1 minutes to complete ___________________________________________________________________________________________________________________ DATA FILE INFORMATION ___________________________________________________________________________________________________________________ The default data stored in the data files are: (1) Raw data file: 'rt18.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: yes (1) - no (0) R = 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: 'rt18_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) TotalScore: the sum of all responses. The response that suggests risk taking gets a point. Factor1_RiskTakingBehavior: the sum of all scores of questions that load on factor 1: q4, q5, q6, q7, q14, q15, q16, q17, q18 => Range: 0-9: the higher the score, the higher the reported risk taking behavior Factor2_RiskAssessment: the sum of all scores of questions that load on factor 2: q1, q2R, q3, q8, q9R, q10R, q11R, q12, q13 => Range: 0-9: the higher the score, the more participant reported to do things without thinking about consequences ___________________________________________________________________________________________________________________ QUESTIONNAIRE SET-UP & SCORING ___________________________________________________________________________________________________________________ 18 questions with yes/no questions: most yes-responses are suggesting of risk taking and are scored as a 1; for a few questions the the no-response is suggesting of risk taking is scored as a 1 => 1 = response suggests risk taking => 0 = response does not suggest risk taking Summary variables: /TotalScore: the sum of all responses. The response that suggests risk taking gets a point. /Factor1_RiskTakingBehavior: the sum of all scores of questions that load on factor 1: q4, q5, q6, q7, q14, q15, q16, q17, q18 => Range: 0-9: the higher the score, the higher the reported risk taking behavior /Factor2_RiskAssessment: the sum of all scores of questions that load on factor 2: q1, q2R, q3, q8, q9R, q10R, q11R, q12, q13 => Range: 0-9: the higher the score, the more participant reported to do things without thinking about consequences ___________________________________________________________________________________________________________________ INSTRUCTIONS ___________________________________________________________________________________________________________________ provided by Millisecond Software - can be edited under section Editable Instructions ___________________________________________________________________________________________________________________ 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.
