Methods Study participants were 1076 adults type 1 509 type 2 567 in clinical trials of Technosphere Insulin who completed the SF-36 health-related quality of life questionnaire and the Inhaled Insulin Treatment Questionnaire IITQ a new instrument assessing diabetes worries perceptions of insulin therapy treatment satisfaction treatment preference and inhaler performance. The IITQ was administered twice prior to treatment initiation in the clinical trials 1-2 weeks apart and several times during the trials. 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 .
