Improved functioning (SDS) was first significant at 12
weeks which may reflect the need for a period of symptom
improvement prior to a change in functioning. Gonzalez-
Isasi et al. (2010) reported improved functioning after
cognitive–behavioral group therapy 12 months after treatment,
but not immediately after treatment or at 6 months.
Notably, IPSRT-G participants improved in functioning
despite only 16% of participants meeting criteria for remission of depressive symptoms. The IPSRT focus on management
of interpersonal stressors and establishment of daily
routinesmay directly improve social, occupational,and home
functioning despite symptom persistence.
