Correction

In our publication [1], the frequencies and percentages of lifetime and current Axis I disorders reported in Table 1 were found to be inaccurate. The values reported in Table 1 of this version have been corrected. All other outcome variables in Table 1 were reported correctly in the original version of the article. The analyses and results in the text were accurate in the original version of the paper.
