Inter-item and item-scale correlations for the AQoLS-Japan scale were moderate to strong. Confirmatory factor analysis results supported the AQoLS-Japan structure but there was evidence of interdependency among some items and factors. Cronbach\u2019s alpha coefficients for internal consistency ranged from 0.73 to 0.97, and intraclass correlation coefficients for scores between test (baseline) and retest (2\u00a0weeks) ranged from 0.65 to 0.82. Convergent and divergent validity and known-groups validity were supported. Evaluation of within-group change demonstrated that the AQoLS-Japan total and domains consistently demonstrated statistically significant improvement (\n                      <jats:italic>p<\/jats:italic>\n                      \u2009&lt;\u20090.001 in all cases) in HR-QoL over time.
