Abstract

OBJECTIVE:

Evaluate the reliability and validity of a new version of the University of California, San Diego Shortness of Breath Questionnaire (SOBQ), a 24-item measure that assesses self-reported shortness of breath while performing a variety of activities of daily living.

DESIGN:

PATIENTS enrolled in a pulmonary rehabilitation program were asked to complete the SOBQ, the Quality of Well-Being Scale, the Center for Epidemiologic Studies Depression Scale, and a 6-min walk with modified Borg scale ratings of perceived breathlessness following the walk.

SETTING:

University medical center pulmonary rehabilitation program.

PATIENTS:

Thirty-two male subjects and 22 female subjects with a variety of pulmonary diagnoses: COPD (n=28), cystic fibrosis (n=9), and postlung transplant (n=17).

MEASUREMENTS AND RESULTS:

The current version of the SOBQ was compared with the previous version, the format of which often resulted in a significant number of "not applicable" answers. The results demonstrated that the SOBQ had excellent internal consistency (alpha=0.96). The SOBQ was also significantly correlated with all validity criteria.

CONCLUSIONS:

The SOBQ is a valuable assessment tool in both clinical practice and research in patients with moderate-to-severe lung disease.
