7 5-point Likert type questions regarding experienced symptoms over the past 12 months
provided by Millisecond - can be edited under section Editable Parameters
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.

| isqFinalScore | 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. |
