Abstract: Purpose: The relationship between cognitive abilities and aphasia rehabilitation outcomes is complex and remains poorly understood. This study investigated the influence of language and cognitive abilities on anomia therapy outcomes in adults with aphasia. Method: Thirty-four adults with chronic aphasia participated in Aphasia Language Impairment and Functioning Therapy. A language and cognitive assessment battery, including 3 baseline naming probes, was administered prior to therapy. Naming accuracy for 30 treated and 30 untreated items was collected at posttherapy and 1-month follow-up. Multiple regression models were computed to evaluate the relationship between language and cognitive abilities at baseline and anomia therapy outcomes. Results: Both language and cognitive variables significantly influenced anomia therapy gains. Verbal short-term memory ability significantly predicted naming gains for treated items at posttherapy (ß = -0.551, p = 0.002) and for untreated items at posttherapy (ß = 0.456, p = 0.014) and 1-month follow-up (ß = 0.455, p = 0.021). Furthermore, lexical-semantic processing significantly predicted naming gains for treated items at posttherapy (ß = -0.496, p = 0.004) and 1-month follow-up (ß = 0.545, p = 0.012). Conclusions: Our findings suggest that individuals' cognitive ability, specifically verbal short-term memory, affects anomia treatment success. Further research into the relationship between cognitive ability and anomia therapy outcomes may help to optimize treatment techniques.
