Can a computerized format replace a paper form in PRO and HRQL evaluation? Psychometric testing of the computer-assisted LCSS instrument (eLCSS-QL).

Purpose: This trial assessed the ability to enhance health-related quality of life (HRQL) and patient-reported outcome (PRO) evaluation in trials and patient management using computer assistance with a handheld device, called a personal digital assistant. The study assessed ease of use and psychometric properties of this approach, comparing the Lung Cancer Symptom Scale (LCSS) paper form with the electronic (eLCSS-QL). Objectives were to: (1) measure completion times; (2) evaluate acceptability by patients, nurses, and physicians; (3) determine the correlation of the eLCSS-QL with the paper version; and (4) determine the feasibility of using a shorter visual analogue scale (VAS) in the electronic version.
