	Pre-test dropouts (N = 5) Md (Q1 – Q3)	Pre-test completers (N = 47) Md (Q1 – Q3)	Post-test (N = 47) Md (Q1 – Q3)	Wilcoxon Z (df = 46)	p-value	Effect size (d)
Burden (0–88)	33.00 (10.50 – 39.25)	33.00 (23.00 – 42.50)	28.50 (22.00 – 36.00)	2.70	0.007	0.32
MBP (0–4)	1.71 (1.09 – 2.04)	1.42 (1.13 – 1.70)	1.29 (1.05 – 1.67)	0.89	0.371	0.14
MBP-related distress (0–4)	1.07 (0.48 – 1.84)	1.85 (1.44 – 2.23)	1.44 (1.03 – 1.94)	2.72	0.007	0.57
Psychological distress (14–56)	23.00 (18.50 – 26.25)	22.50 (19.00 – 28.00)	20.50 (18.00 – 24.50)	3.36	0.001	0.48
Self-efficacy (0–10)	10.00 (9.00 – 10.00)	8.00 (7.00 – 8.50)	8.00 (7.00 – 9.00)	-0.13	0.897	-0.02

For all the variables listed, higher scores indicate higher levels, MBP Memory and behavioural problems, for burden, scores above 18 indicate an important burden and scores above 32 a severe burden; among the 5 dropouts, 2 declined to participate before the start of the intervention and 3 failed to provide post-test measures.
