TL;DR: These three shortened versions of the Asthma Control Questionnaire can be used in large clinical trials without loss of validity or change in interpretation.

TL;DR: The results show that HRQL in COPD deteriorates with disease severity and with age, and a relationship between HRQL and disease severity obtained by lung function is shown.

TL;DR: The subjective recording in diary cards of symptoms of itch, sneeze, nose running, and blockage, with the use of a rating scale to indicate the level of severity, is usual for clinical trials in allergic rhinitis.

TL;DR: This study confirms that the CRQ and SGRQ are substantially more responsive than generic measures, and suggests particularly strong responsiveness for the self-administered CRQ.

TL;DR: Self-administration and standardisation of the Chronic respiratory questionnaire maintains validity and responsiveness relative to the interviewer-administered chronic respiratory questionnaire, and challenges the assumption that interviewer- administered questionnaires are superior to self- Administered questionnaires in older patients with chronic respiratory disease.
