A 44-year-old female with major depressive disorder initiated interpersonal therapy 14 weeks ago with the identified problem area of role transition following her divorce eight months ago. At baseline, her PHQ-9 was 19 and she reported social withdrawal, difficulty establishing a new daily routine, profound grief over loss of her identity as a married person, and strained relationships with mutual friends. After 14 weekly sessions, her PHQ-9 is 9, she has reconnected with two close friends, started a part-time volunteer position, and reports feeling more comfortable with her single identity. However, she continues to endorse feelings of loneliness on weekends, occasional tearfulness when reminded of her marriage, and has not yet begun dating despite expressing interest. She has met with her therapist for the expected 12-16 session acute treatment course. The PMHNP is evaluating the treatment response and determining next steps. Which of the following best represents the appropriate evaluation of IPT outcomes?
