Cut off for reduced immune functioning: ISQ < 6. ISQ_finalScore: Range 0-10 Wilod Versprille et al. (2019) recommended also assessing current immune and health status in conjunction with the ISQ. Question A assess percieved immune functioning and Question B assess perceived general health rated on a scale from 0 = very poor, 10 = excellent. Question C assess perceived reduced immune fitness at this moment (response options: yes or no). Question D asks participants whether they have a chornic disease (response options: yes or no). If participants answer yes to this question they are asked to specify the chronic disease. ___________________________________________________________________________________________________________________ QUESTIONNAIRE SET-UP & SCORING ___________________________________________________________________________________________________________________ Each of the 7 questions is scored on a scale from 0 (never) to 4 (almost always). The raw score (0-28) is then converted to a final score (0-10) according to the following guidelines: expressions.ISQ_rawScore >= 15 => Final Score = 0; expressions.ISQ_rawScore = 14 => Final Score = 1; expressions.ISQ_rawScore = 13 => Final Score = 2 expressions.ISQ_rawScore = 11 OR 12 => Final Score = 3 expressions.ISQ_rawScore = 10 => Final Score = 4 expressions.ISQ_rawScore = 8 OR 9) => Final Score = 5 expressions.ISQ_rawScore = 7 => Final Score = 6 expressions.ISQ_rawScore = 6 => Final Score = 7 expressions.ISQ_rawScore = 5 => Final Score = 8 expressions.ISQ_rawScore = 3 OR 4 => Final Score = 9 anything under 3 => Final Score = 10 Interpretation: 0 = very poor, 10 excellent perceived immune status Cut off for reduced immune functioning: ISQ < 6. ___________________________________________________________________________________________________________________ INSTRUCTIONS ___________________________________________________________________________________________________________________ provided by Millisecond Software - can be edited under section Editable Parameters ___________________________________________________________________________________________________________________ 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: /pageinstructions: the instructions that appear at the top of each surveypage /quitinstructions: the instructions to quit the questionnaire Note: the quitcommand can be changed under DEFAULTS
