Unweighted mean values and standard deviations are reported for each outcome measure, with t-values, mean differences between T1 and T2, and 95% confidence intervals of the differences. The number and percentage of cases in each score category are also reported for easy interpretation. Weighted comparisons are reported in the final column on the right.
GAD-7 (anxiety) scores: 0–4, none; 5–9, mild; 10–14, moderate; 15+, severe. PHQ-9 (depression) scores: 0–4, none; 5–9, mild; 10–14, moderate; 15–19, moderately severe; 20+, severe. ISI-3 (insomnia) scores: 0–6, not clinically significant; 7+, clinically significant. NIDA-ASSIST (substance misuse) scores: 0–3 (0–3.49), low risk; 4–26 (3.5–26.49), moderate risk; 27+ (26.5 or above), high risk. SBQ-R (suicidality) scores: 0–6, not clinically significant; 7+, clinically significant.
