TABLE 2.

Frequencies of the four items measuring goal setting and evaluation, means of patients' perceived lack of goal clarity, and results of the GLM univariate tests per item

Item	Response options	n	M	95% CI	F	p	η p 2
1. At the start of the treatment, were one or more treatment goals set?	Yes	570	3.13	[3.04, 3.22]
	No	171	3.91	[3.75, 4.08]
	Total	741	3.31		64.92	<.001	η p 2 = .09
2. Did you set this treatment goal or these treatment goals together with your therapist?	Yes	520	3.09	[3.00, 3.18]
	No	50	3.68	[3.38, 3.97]
	Total	570	3.13		14.14	<.001	η p 2 = .03
3. Are your treatment goal(s) discussed during the therapy sessions?	Yes, at (almost) every session	165	2.83	[2.68, 2.99]
	Often	184	2.91	[2.77, 3.06]
	Sometimes	171	3.34	[3.19, 3.49]
	(Almost) never	50	4.32	[4.04, 4.59]
	Total	570	3.14		34.39	<.001	η p 2 = .17
4. Is your progress measured during the treatment? Consider the completion of questionnaire(s) or having an evaluation discussion, and so on.	Yes, at (almost) every session	149	2.95	[2.77, 3.12]
	Often	284	3.05	[2.92, 3.18]
	Sometimes	237	3.63	[3.49, 3.76]
	(Almost) never	71	4.06	[3.81, 4.32]
	Total	742	3.31		28.64	<.001	η p 2 = .12

Note: The potential range of patients' perceived lack of goal clarity is from 1–7. M = estimated marginal means based on the GLM univariate tests, controlled for the number of treatment sessions patients completed so far.

Abbreviations: CI, confidence interval; GLM, general linear model; η _p ², partial eta².
