4.20, p=.042, partial eta squared = .029, with both groups showing a reduction on the total problem score between admission and discharge (see Table 3).
The main effect comparing the EO group with the AO group was not significant, F (1, 143) = 2.21, p=.140, partial eta squared = .015, suggesting no differences in outcome between the onset groups.

At discharge, parents involved in the treatment of their child were sent a TOR-J. Because the TOR-J was introduced in October 1997, parents of 22 patients have not received a questionnaire because their child was already discharged. Besides, five patients had no parents involved. Therefore, the TOR-J was sent to 113 parents. Of them, 83 (73.5%) completed and returned the questionnaire. The relationship between treatment outcome on the GSI and the TOR-J “treatment results” scale was examined using Pearson product-moment correlation coefficient. There was a weak but positive correlation between both variables (r=.33, n=83, p=.002).
Clinical significance of change
To reveal how many patients deteriorated or recovered during treatment, the procedure of clinically significant change was used, to examine whether the patients post-test scores crossed the cutoff point toward better functioning (Jacobson & Truax, 1991). Based on the mean and standard deviation of the normal population, the true difference and the true post-score were calculated. At discharge, the majority of the sample (58.6%) had recovered or improved (GSI; see Table 4).
Subsequently, to control for the staggered design, a chi-square analysis was performed between the three time cohorts (1995-1998, 1999-2002, and 2003-2008) and the categories of clinical significant change of the GSI (i.e., recovered, improved,
