Development and psychometric properties of the Pulmonary-specific Quality-of-Life Scale in lung transplant patients.

ABSTRACT:

Background

The Pulmonary-specific Quality-of-Life Scale (PQLS) was developed to measure quality of life (QoL) among patients awaiting lung transplant. The objective of this study was to determine the psychometric properties of the PQLS, identify empirically derived sub-scales, and examine ability to detect changes in pulmonary-specific QoL scores after lung transplantation.

Methods

Data were derived from the INSPIRE trial, a dual-site randomized controlled trial of coping skills training in 389 lung transplant candidates (obstructive [48.3%], restrictive [24.2%], cystic fibrosis [13.6%], and other [13.9%]). Cronbach alpha was calculated to assess the internal reliability of the PQLS (n = 388). Test-retest reliability was assessed with correlation coefficients between baselin
