^*p<.05 difference between treatment groups

^**p <.01 difference between treatment groups

Estimate for treatment group is interpreted as group difference; Estimate for time X treatment group is interpreted as group change over time; Reference group is the IPT-P group; All analyses controlled for age, baseline antidepressant medication use, and session attendance; social function and pain analyses also controlled for baseline Hamilton Rating Scale for Depression score; Interpersonal Function was measured on the Inventory of Interpersonal Problems; Pain was measured on the Multidimensional Pain Inventory.
