RQ2.1 Test–Retest Reliability of SoC Measures
T0 and T1 data were used. The 2-week interval between T0 and T1 (with no intervention) was assumed long enough for respondents to forget their answers, and short enough for readiness to remain stable. Reliability of the 10 new TB-specific SoC scales was determined by calculating ICCs and their 95% confidence intervals (95% CIs) (single-measurement, absolute-agreement, two-way mixed-effects model;
