Conclusion: Reliability coefficients can be reported with 95% CIs by statistical software to evaluate the internal
consistency of respondent scores on questionnaire items. The SPSS syntax procedures for estimating the reliability of
the 95% CI, expected score generation and visual skewness analyses are demonstrated in this study. We recommend
that effect sizes such as a 95% CI be reported along with p values reporting significant differences in quality-of-life
studies.
