简要总结
The goal of this clinical trial is to compare the effectiveness of traditional Semantic Feature Analysis (SFA) treatment to a modified SFA protocol that includes Metacognitive Strategy Training (SFA+MST) for adults with acquired aphasia. The main questions it aims to answer are:
- What are the comparative outcomes in picture naming accuracy and strategy use during picture naming following 2 months of traditional SFA versus SFA + MST in adults with acquired aphasia?
- What are the comparative outcomes in percent of informative content and rate of informative content during spontaneous speech production following 2 months of traditional SFA versus SFA + MST in adults with acquired aphasia?
Researchers will compare outcomes between these two treatments to see if SFA+MST yields larger effects in picture naming and spontaneous speech outcomes than traditional SFA.
Participants will complete:
- 5-7 pre-treatment assessment sessions where they will be asked to name pictures, tell stories/describe pictures, answer questions, and complete questionnaires,
- 3 treatment sessions of SFA *OR* SFA+MST per week for 8 weeks, for a total of 24 sessions,
- 7 weekly probes (i.e., short, intermittent assessments throughout the treatment phase),
- 3 post-treatment assessment sessions immediately after treatment ends, where they will complete the same assessment tasks as they did pre-treatment (e.g., naming pictures, telling stories, etc.),
- 2 retention assessment sessions, one 30 days and the other 60 days following the final treatment session, where they will be asked to name pictures, tell stories/describe pictures, and describe what they learned during the study.

研究组 & 干预措施
Traditional Semantic Feature Analysis
A portion of the study participants will participate in traditional Semantic Feature Analysis treatment, as described in Gravier, M. L., Dickey, M. W., Hula, W. D., Evans, W. S., Owens, R. L., Winans-Mitrik, R. L., & Doyle, P. J. (2018). What matters in semantic feature analysis: Practice-related predictors of treatment response in aphasia. American Journal of Speech-Language Pathology, 27(1S), 438-453. https://doi.org/10.1044/2017\_AJSLP-16-0196. Briefly, this treatment involves naming pictures of objects, describing the objects' features (e.g., category membership, physical attributes, etc.), and creating sentences using the objects' names.

Semantic Feature Analysis + Metacognitive Strategy Training
A portion of the study participants will participate in traditional Semantic Feature Analysis treatment, as described in Tilton-Bolowsky, V. E., Brock, L., Nunn, K., Evans, W. S., & Vallila-Rohter, S. (2023). Incorporating metacognitive strategy training into semantic treatment promotes restitutive and substitutive gains in naming: A single-subject investigation. American journal of speech-language pathology, 32(5), 1979-2020. https://doi.org/10.1044/2023\_AJSLP-22-00230. Briefly, this treatment involves metacognitive teaching and practice, naming pictures of objects, describing the objects' features (e.g., category membership, physical attributes, etc), creating sentences using the objects' names, debriefing on overall performance, and discussing recent and future opportunities for strategy implementation in real life.

结局指标
主要结局
Confrontation naming accuracy
时间窗: Change from Baseline through study completion, an average of 6 months
Participants will complete a 60-item confrontation naming assessment before, during, and after treatment. We will calculate the total number of items that participants name accurately across study phases.
Independent word-finding strategy use
时间窗: Change from Baseline through study completion, an average of 6 months
Using the 60-item confrontation naming assessment, we will evaluate instances in which participants independently use a specific word-finding strategy (describing or talking around the word) in instances where they cannot name items successfully, and calculate the proportions of incorrect responses with and without strategy use across study phases.
次要结局
- Discourse informativeness(Change from Baseline through study completion, an average of 6 months)
- Discourse efficiency(Change from Baseline through study completion, an average of 6 months)
