Table 3. Results of the two groups presented separately for all / for only clinical participants.

Statistical analyses/number of participants analyzed	LSAS-SR	SPIN	SIAS	SPSQ	BDI-II	ATQ	ABS-II
Results for the first intervention group (the iCBT group)
Univariate ANCOVA (comparing pre- to post-intervention scores)
Clinical and subclinical Ps (n = 76)	34.12**	43.30**	44.71**	43.74**	18.11**	9.72**	8.46**
Only clinical Ps (n = 66)	31.28**	44.13**	40.82**	39.44**	16.16**	12.04**	5.83**
Paired sample t-test (comparing post-intervention to six-month follow-up scores)
Clinical and subclinical Ps (n = 76)	1.39	3.43**	3.27**	2.75*	.10	2.26*	2.59**
Only clinical Ps (n = 66)	.89	3.13**	3.00**	2.35*	-.22	2.58*	2.33*
Results for the second intervention group (the former wait-list control group)
Paired sample t-test (comparing pre- to post-intervention scores)
Clinical and subclinical Ps (n = 33)	8.39**	9.29**	7.18**	8.93**	5.71**	5.52**	5.84**
Only clinical Ps (n = 28)	7.29**	8.89**	6.35**	7.87**	4.29**	5.15**	5.09**

Notes: 1) The values presented in Table 3 represent the Univariate ANCOVAs and the paired sample t-test for the main outcome measures. 2) The wait-list control group (WLCG) received the same psychosocial intervention after the iCBT group ended it (i.e., starting from week ten). The data presented in the bottom of Table 3 summarized the differences between the pre- and post-intervention scores obtained by the second intervention group (i.e. the former WLCG). Abbreviations: LSAS-SR = Liebowitz Social Anxiety Scale–Self-Report version; SPIN = Social Phobia Inventory; SIAS = Social Interaction and Anxiety Scale; SPSQ = Social Phobia Screening Questionnaire; BDI-II = Beck Depression Inventory-II; ATQ = Automatic Thoughts Questionnaire; ABS-II = Attitude and Belief Scale-II. Ps = Participants.
