Aim: To determine the reliability, criterion validity and patient acceptability of the ICQ-S. Methods: At days 0 and 14, adults with doctor-diagnosed asthma and prescribed an ICS inhaler, completed the ICQ, ICQ-S, 6-item ACQ and AQLQ(s). The intraclass correlation coefficient (ICC) between day 0 and 14 ICQ-S assessed test-re-test reliability. Cronbach's alpha (α) coefficient and item-total correlations tested the internal consistency of ICQ-S. Associations (Spearmans rho) between the ICQ and ICQ-S total score and relative associations of the ICQ and ICQ-S with the AQLQ(s) assessed criterion validity. Patients reported duration and perceived difficulty (1=very difficult, 5=very easy) of ICQ-S completion. Results: 62 patients (female 63%, mean age 54 (SD 13) yrs., mean ACQ 0.79 (SD 0.83), median ICS dose 1000µg (IQR 500,1000)) were eligible. The ICC between day 0 and 14 ICQ-S scores was 0.90, α coefficient was 0.90 and all item-total correlations were rho≥0.20. ICQ and ICQ-S were strongly associated (rho=0.86) and similarly associated with the AQLQ(s) (ICQ rho= -0.58, (ICQ-S rho= -0.62). 81% patients completed the ICQ-S within 5 minutes and 97% reported that it was not difficult to fill in. Conclusion: The ICQ-S is a patient-friendly tool which retains the reliability and validity of the original ICQ scale but is brief enough for monitoring/managing inhaled steroid side effects in clinical practice.
