Inhaler performance was assessed at follow-up visits after participants had used the device. Results IITQ subscales had acceptable reliability alpha median and test-retest correlations intraclass correlation coefficient median floor effects and ceiling effects were minimal. Reliabilities for inhaler performance measures were acceptable alpha median there were no floor effects and ceiling effects were moderate. There were several modest associations between IITQ scores and measures of health status. Diabetes worries were lower for participants who had better mental health type 2 and for those with higher BMI perceptions of insulin therapy were more favorable for participants who had better physical and mental health treatment satisfaction was higher for patients who had lower BMI type 2 lower .
