Abstract

Background: Alcohol Use Disorder (AUD) is associated with significant cognitive impairments, particularly in executive functioning, yet evidence for cognitive rehabilitation therapy (CRT) in low-resource settings remains limited. This study evaluated the efficacy of CRT for mild executive dysfunction among male AUD patients in Zambia. Methods: A randomized controlled trial was conducted with 56 participants (aged 18-40 years) recruited from a residential rehabilitation center in Lusaka. Participants were randomized to either an 8-week CRT program (Brain Wave-R, n=28) or active control (painting sessions, n=28), both delivered alongside standard treatment. Executive function was assessed pre- and post-intervention using the Zambian Neurobehavioral Test Battery, including the Wisconsin Card Sorting Test (WCST), Colour Trails Test 2 (CTT), and Stroop Test. Results: The CRT group demonstrated significant improvements in response inhibition (Stroop Test: fewer errors, p=0.01; more words completed, p
