  Abstract

Objective The psychometric properties of the Chinese version of the Pediatric Quality of Life InventoryTM (PedsQLTM) Cancer Module were investigated. Methods This instrument and the Generic Core Scales were administered to 359 pediatric patients with cancer (5–18 years) and 413 parents of such patients (2–18 years old). Results Seven and eight factors were, respectively, identified for the patient and parent versions. The Cronbach's alpha coefficients were respectively .89 and .92 for the total scale, and respectively .75–.90 and .76–.93 for the subscales of the patient and parent versions. Test–retest reliability coefficients exceeded .60 for most cases. The total/subscale scores of the Cancer Module significantly correlated with those of the Generic Core Scales. Some of the subscales could distinguish between on-treatment and off-treatment patients. Conclusions The psychometric properties of the patient and parent versions of the Chinese PedsQLTM Cancer Module were found acceptable.

Key words: adolescents; children; cancer; health-related quality of life; Pediatric Quality of Life InventoryTM.
