Overview
Brief Summary
This study will use a randomized controlled trial design to evaluate the effect of two evidence-based treatments for adults with mild Primary Progressive Aphasia (PPA). The aim of the study is to help us better understand the effects of speech language therapy on communication abilities in individuals with PPA.
Participants with a diagnosis of PPA and their actively-engaged care partners will be involved in the study for 12 months. Each participant will receive a laptop equipped with the necessary applications and features for the study. Participants will receive 5 evaluations and 15 speech therapy sessions with a licensed speech therapist, as well as access to Communication Bridge, a personalized web application to practice home exercises that reinforce treatment strategies. There are no costs to participate in this study.

Eligibility Criteria
Inclusion Criteria
- Not provided
Exclusion Criteria
- •A dementia diagnosis other than Primary Progressive Aphasia
- •Participation is co-enrolled in an outside speech language therapy program during the study course.
- •Communication partners will be excluded if they have a pre-existing communication impairment that would affect study participation (e.g., aphasia, dementia)
- •Medical records will be requested and reviewed to determine eligibility.
Outcomes
Primary Outcomes
Change in Communication Confidence (CCRSA)
Time Frame: 5 assessment time points through study completion - Baseline, Post Intervention 1 (3 months), Six months, Post Intervention 2 (9 months), and 12 months
Communication Confidence Rating Scale in Aphasia, a 0-100 numeric rating scale with 0 representing 'not confident' and 100 representing 'very confident'. Higher scores indicate greater confidence.
Change in Communication Participation Item Bank (CPIB)
Time Frame: 5 assessment time points through study completion - Baseline, Post Intervention 1 (3 months), Six months, Post Intervention 2 (9 months), and 12 months
Communication Participation Item Bank is a 4-point rating scale with 0 representing 'very much' and 3 representing 'not at all'. Higher scores indicate greater severity of communication challenges. We are reporting on change in CPIB scores using T-scores. The Communicative Participation Item Bank (CPIB) T-score range is as follows: T57.5 and above: Represents a "normal" experience of communicative participation or "minimal problems" T57.5-T45: Represents mild challenges T45-T35: Represents moderate challenges T35 and below: Represents severe challenges The CPIB is a patient-reported instrument that measures communicative participation. The mean T-score is 50, and the standard deviation is 10. Higher scores are more favorable, indicating less interference in participation. The ideal score, or someone who reports no problems with communicative participation, would be a T-score of 74.3
Change in Communication Participation Person Centered Goals
Time Frame: 4 assessment time points through study completion - Post Intervention 1 (3 months), Six months, Post Intervention 2 (9 months), and 12 months
This measure assesses progress toward communication participation goals using Goal Attainment Scaling (GAS). Participants developed personalized goals, each set to a baseline value of '0'. Progress was tracked using a 7-point scale, where -3 represents 'no longer participating' and +3 represents 'exceeded goal'. Higher scores indicate better progress toward goal achievement. Goals were evaluated at 3, 6, 9, and 12 months, with the results reported as the percentage of goals that: Worsened (scores of -1, -2, or -3) No change (score remained at 0) Improved (scores of +1, +2, or +3), including getting close to, reaching, or exceeding the goal. The table below presents the percentage of goals falling into each of these categories at each assessment point.
