Notes: Median and interquartile range are provided for comparison because of the small sample size.

Values are means ± standard deviations unless noted.

PHQ: Patient Health Questionnaire; WAI-SF: Working Alliance Inventory—Short Form; IQR: interquartile range.

^aThe statistical significance of individual variables was assessed with the Cochran-Mantel-Haenszel χ² tests with df = 7.
