The aim of this study was to investigate the long-term effectiveness (3-4 years later) of an online intervention that was previously found to effectively reduce depressive symptoms in people with HIV on the short term.

Background: A previous randomized controlled trial in older adults with anxiety symptoms found no differences between a brief blended Acceptance and Commitment Therapy (ACT) intervention and brief face-to-face Cognitive Behavior Therapy (CBT) regarding anxiety symptom severity at posttreatment and 12-month follow-up.
