Weekly Anxiety Scores.
P2: Rapid response to treatment (weeks 2 and 3) corresponded with sessions on motivation and psychoeducation.
P5: Elevated BAI at the beginning of treatment (sessions 1–5) coincided with external stressor. BAI trended downward from sessions 3–12. P8: Initial increase in slope on BAI/STAI-S (weeks 2/3–5) coincided with increased “off” periods related to DBS reprogramming. There was a subsequent decline in BAI/STAI-S/OASIS from weeks 5–12. Throughout treatment, she reported several medically-warranted adjustments in dopaminergic dose and DBS settings, which worsened motor complications. These changes likely affected her anxiety ratings, but these changes were consistent from weeks 1–10 of the intervention phase, and the downward trend in anxiety scores began in week 5.
