• W2912191128 abstract "Event Abstract Back to Event Cognitive predictors of response to semantically-based naming treatment in chronic aphasia Michelle Gravier1*, Michael W. Dickey1, 2, William Hula1, 2 and Patrick Doyle1, 2, 3 1 VA Pittsburgh Healthcare System, GRECC, United States 2 University of Pittsburgh, Communication Science and Disorders, United States 3 VA Pittsburgh Healthcare System, Audiology and Speech Pathology, United States INTRODUCTION A growing body of evidence suggests that cognitive factors like executive functioning, visuospatial skills, memory, and attention may be predictive of aphasia treatment outcomes [1-3]. For example, Lambon Ralph and colleagues [1] found that scores on three cognitive measures (Test of Everyday Attention [TEA] Elevator Counting with distraction subtest; Rey Figure copy and delayed-recall subtests) correlated significantly with naming improvements following combined phonemic/orthographic cueing therapy. However, it is unknown whether these measures predict response to other types of treatment, or generalization to untreated items: Lambon-Ralph and colleagues only analyzed treated items. The current study investigated whether cognitive measures were predictive of acquisition and generalization in response to Semantic Feature Analysis (SFA[4]), a commonly-used semantically-focused naming treatment. METHOD Participants: Twenty-six adults with chronic aphasia following single left-hemisphere stroke participated. All participants were right-handed with normal or corrected hearing and vision and no history of other neurological disease. Assessment: Prior to treatment, all participants were given a battery of assessments including: Camden Memory Test[5] Topographical and Word Memory subtests (episodic memory); TEA[6] Elevator Counting with and without Distraction subtests (attention); the Rey Complex Figure Test[7] copy, immediate-, and delayed-recall subtests (visuospatial ability and memory); and the Wisconsin Card Sort Test[8] (problem solving). Treatment: All participants received intensive SFA treatment as part of an ongoing clinical trial. Treatment was administered 4-5 days per week for 4 weeks, in two daily sessions of approximately 120 minutes each. Analysis: The outcome measure was naming-probe accuracy for both treated and semantically-related untreated items at entry (immediately before first treatment session) and exit (morning after final treatment session). Item-level data were analyzed using multilevel generalized linear regression with a logistic link function in R. Each cognitive measure was tested in a separate model including main effects and interactions of cognitive measure, probe time (entry/exit), and item type (treated/untreated). Models also included aphasia severity (Comprehensive Aphasia Test[9] modality mean T-score) as a covariate and random intercepts for items and participants. RESULTS A significant interaction of cognitive measure and probe time was found for the Camden Word Memory Test (p= 0.03) and the TEA with Distraction subtest (p= 0.01), indicating that higher scores on both measures predicted greater entry-to-exit naming improvement, controlling for aphasia severity. However, the three-way interactions with probe time and item type were not significant (p> 0.4), suggesting that the measures were predictive of both acquisition of treated items and generalization to untreated items. No other two- or three-way interactions reached significance. DISCUSSION The finding that TEA significantly predicted SFA treatment response (both acquisition and generalization) replicates and extends previous findings[1]. It also suggests that attention may be a general prerequisite for response to different aphasia-treatment approaches. However, the fact that Rey Figure subtests were not predictive of SFA response suggests that visuospatial skills may be of greater importance for treatments relying primarily on phonemic/orthographic cues[1]. Furthermore, the finding that Camden Word Memory predicted response to SFA, but not to semantic/orthographic cueing[1], suggests that episodic memory for words may be particularly important for semantically-based treatments.
