Table 1. Results of one-sample t-tests on CORE-OM change scores for Study 1.

	t	DF	Mean	Lower CI	p	p cor *
Global distress	3.679	147	2.003	1.102	< .001	s
Distress	3.821	147	1.838	1.042	< .001	s
Functioning	3.766	147	0.811	0.454	< .001	s
Problems or symptoms	2.2	147	0.733	0.182	.014	ns
Wellbeing	1.85	147	0.294	0.031	.033	ns

In all cases the alternative to the null hypothesis is that the true mean is > 0.

*Adjusted using a Bonferroni correction for multiple hypothesis testing, where p_cor gives whether the result remain significant after being evaluated against p_crit, where p_crit = p/k, where k is the number of hypotheses being tested (s = significant; ns = not significant).
