Integration of e-Health technologies for purposes of both assessment and intervention has recently become an interest area in pediatric psychology. The purpose of this study is to present psychometric characteristics of a technology-based (i.e., tablet administration) approach for measuring quality of life (QOL) in children. Eighty children (8–12 years) completed the Quality of Life Systemic Inventory for Children (QLSI-C) twice over a 2-week delay, in a crossover design that used paper and tablet-based modes of administration. Equivalence of scores across methods was examined using intraclass correlation coefficients (ICC), augmented by paired t test and Pearson’s correlations. Test–retest reliability was assessed using paired t test and Pearson’s correlations while internal consistency was assessed using Cronbach’s coefficient. Results showed a good concordance across methods of administration (ICCs = .72 to .91; r = .56 to .83). Paired t test showed no significant differences between the tablet and paper version of the QLSI-C. Internal consistency reliability yielded acceptable Cronbach’s alphas for all QLSI-C scores, with all α > .70. Test–retest reliability for the tablet-administered QLSI-C was good (r = .66 to .90). Paired t test showed no significant difference between Time 1 and 2 for the QLSI-C scores, except for the state score. Findings established the reliability of the tablet-administered QLSI-C scores. This technology approach to assessment is more attractive for children, decreases time for administration, and enhances the ease of scoring. These advantages might encourage both clinicians and researchers to consider using e-Health developments in assessment in pediatric psychology.
