Confidence
High: the new condition is named in the study's own listed conditions. Of 351 hand-checked studies reclassified this way, 68% were exactly right and 84% in the right disease family; the registry's first term was right for 5% (measured 2026-10-21). How we classify →

Study summary

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.

    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.

Interventions

  • BehavioralSemantic Feature Analysis (traditional)

    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. It does not include direct metacognitive strategy training.

  • BehavioralSemantic Feature Analysis + Metacognitive Strategy Training

    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.

What researchers measure

Primary outcomes

  1. Confrontation naming accuracy

    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.

    Time frame: Change from Baseline through study completion, an average of 6 months

  2. Independent word-finding strategy use

    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.

    Time frame: Change from Baseline through study completion, an average of 6 months

Secondary outcomes

  1. Discourse informativeness

    Participants will describe picture scenes and tell stories. We will calculate the amount of informative content in their descriptions/stories using Content Information Unit (%CIU; Nicholas \& Brookshire, 1993) analysis for descriptions/stories across study phases.

    Time frame: Change from Baseline through study completion, an average of 6 months

  2. Discourse efficiency

    Participants will describe picture scenes and tell stories. We will calculate the rate of informative content in their descriptions/stories using Content Information Unit (CIU/minute; Nicholas \& Brookshire, 1993) analysis for descriptions/stories across study phases.

    Time frame: Change from Baseline through study completion, an average of 6 months

Other outcomes

  1. Explicit strategy knowledge

    Participants will be asked to identify what they can do in moments of word-finding difficulty and what types of information they can provide in those moments, across study phases. There are six types of information that will be discussed during the treatments.

    Time frame: Change from Baseline through study completion, an average of 6 months

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Jun 25, 2026, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
