Semantic Feature Analysis + Metacognitive Strategy Training for Acquired Aphasia
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial tests two types of speech therapy for adults with speaking difficulties due to conditions like a stroke. The study compares traditional Semantic Feature Analysis (SFA), which involves naming and describing objects, with a new method that adds Metacognitive Strategy Training (SFA+MST) to help participants reflect on their thinking and strategies. Researchers aim to determine which approach better improves naming and speaking. Suitable candidates for this trial are English-speaking adults who have experienced aphasia for at least six months following a stroke or brain injury, without other serious conditions affecting their brain or speech capabilities. Participants will attend several therapy sessions and assessments to track their progress. As a Phase 2 trial, this research measures the treatment's effectiveness in an initial, smaller group, offering participants a chance to contribute to important advancements in speech therapy.
Do I need to stop my current medications for this trial?
The trial information does not specify whether you need to stop taking your current medications. It's best to discuss this with the trial coordinators or your doctor.
Is there any evidence suggesting that this trial's treatments are likely to be safe?
Research has shown that Semantic Feature Analysis (SFA) is generally safe for people with aphasia. A review of studies on SFA found no major safety concerns, indicating it is a safe option for participants. This treatment involves naming objects and describing their features, a common therapy method without known serious side effects.
Previous trials have also shown the combination of Semantic Feature Analysis with Metacognitive Strategy Training (SFA+MST) to be safe. This approach includes metacognitive strategy training, which involves thinking about and improving cognitive processes. Early trials with SFA+MST reported no significant negative effects, indicating it is well-tolerated.
Both treatments have been tested in clinical settings, and neither has raised major safety issues. These findings reassure participants about the safety of these approaches.12345Why are researchers excited about this trial's treatments?
Researchers are excited about these treatments for acquired aphasia because they offer a fresh approach to improving language skills. The traditional Semantic Feature Analysis helps patients by having them name objects, describe their features, and form sentences, which strengthens their language retrieval skills. The addition of Metacognitive Strategy Training in the experimental treatment enhances this approach by teaching patients to think about their thinking, allowing them to reflect on their performance and strategize for real-world use. This combination could lead to more significant and lasting improvements in communication abilities compared to standard therapies that don't incorporate metacognitive elements.
What evidence suggests that this trial's treatments could be effective for acquired aphasia?
Studies have shown that Semantic Feature Analysis (SFA) helps people with acquired aphasia improve their ability to find the right words. This method focuses on the features of objects, such as their category and physical characteristics. In this trial, one group of participants will receive traditional SFA treatment, while another group will receive SFA combined with Metacognitive Strategy Training (MST). Research suggests that MST can enhance the benefits of SFA by encouraging patients to think about their own thinking, helping them apply new strategies in everyday life. Initial findings indicate that using SFA with MST can lead to better accuracy in naming objects and more natural speech.36789

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.
