Uncertainty and Perceived Control as Predictors of Communicative Participation and Mental Health in Adults Who Stutter

Purpose: This study examined the role of uncertainty and perceived control in predicting the communicative participation and mental health of adults who stutter. Method: Two hundred sixty-nine adults who stutter completed measures of uncertainty about stuttering, perceived control of stuttering, communicative participation, and global mental health. In addition, participants self-reported on a variety of demographic and speech-related measures. Correlational analyses and hierarchical regression were performed to determine associations between variables of interest. Results: Uncertainty accounted for significant variance in communicative participation and global mental health after statistically controlling for the effects of demographic and speech-related variables. Perceived control accounted for significant variance in communicative participation over and above what was accounted for by demographic variables, speech-related variables, and uncertainty. Conclusions: The findings suggest that uncertainty about stuttering and perceived control of stuttering should be accounted for during assessment and intervention with adults who stutter. Interventions that specifically target uncertainty and perceived control may be useful in improving therapeutic outcomes for individuals who stutter.

From Speech Acoustics to Communicative Participation in Dysarthria: Toward a Causal Framework

Purpose: We proposed and tested a causal instantiation of the World Health Organization's International Classification of Functioning, Disability and Health (ICF) framework, linking acoustics, intelligibility, and communicative participation in the context of dysarthria. Method: Speech samples and communicative participation scores were collected from individuals with dysarthria ( n = 32). Speech was analyzed for two acoustic metrics (i.e., articulatory precision and speech rate), and an objective measure of intelligibility was generated from listener transcripts. Mediation analysis was used to evaluate pathways of effect between acoustics, intelligibility, and communicative participation. Results: We observed a strong relationship between articulatory precision and intelligibility and a moderate relationship between intelligibility and communicative participation. Collectively, data supported a significant relationship between articulatory precision and communicative participation, which was almost entirely mediated through intelligibility. These relationships were not significant when speech rate was specified as the acoustic variable of interest. Conclusion: The statistical corroboration of our causal instantiation of the ICF framework with articulatory acoustics affords important support toward the development of a comprehensive causal framework to understand and, ultimately, address restricted communicative participation in dysarthria.

Toward Developing Outcome Measures in University-Based Aphasia Programs: Perspectives From the Aphasia Communication Enhancement Program

Purpose University-based aphasia programs are a vital part of the continuum of care for aphasia. However, research on program outcomes is limited, with inconsistencies in the use of outcome measures. We present a pilot retrospective study of the Aphasia Communication Enhancement (ACE) program at Western Michigan University. This study aimed to examine the types of outcome measures employed in the ACE program that target the core outcome set (COS) and to analyze their outcomes for participants with aphasia and their care partners. Method The ACE participants with aphasia were identified by the process of chart review. The selected case files were examined for the type of outcome measures used and analyzed for quantitative outcomes on formal assessments. We also presented examples of communicative participation goals and outcomes by conducting a qualitative analysis of the therapy reports. Additionally, transcripts from a prior focus group discussion involving ACE care partners were used to examine their perceptions of ACE by conducting a thematic analysis. Results A systematic chart review of 44 case files led to the selection of three ACE participants for analysis. Their chart review revealed the use of a variety of outcome measures for language, quality of life, and emotional well-being, with documented improvements in language in the three participants. Specific examples describe how the individualized communicative participation goals were strategically targeted and how the corresponding outcomes were documented. The thematic analysis of care partner perceptions revealed five themes, as follows: ACE serves a needed purpose , enjoyment for clients , benefits of ACE for clients , benefits of ACE for care partners , and recommendations for ACE . Conclusions Challenges and strategies for implementing COS outcome measurement and documentation protocols in university-based aphasia programs are discussed. The outcome measurement protocol can support the systematic measurement of meaningful outcomes for participants with aphasia and facilitate the acquisition of competencies for student clinicians in this consensus-based model.

Examining Social Networks in Older Adults: What Predicts Communicative Participation?

Purpose Social isolation is linked to cognitive decline and depression, which can be risk factors for developing dementia. The purpose of this study was to determine which of a variety of factors were associated with communicative participation as measured by social network size. Method Three hundred thirty-seven adults aged 65 years or older were administered assessments to evaluate social network size, cognition, hearing handicap, and quality of communicative participation. Results Cognition, education, living setting, and quality of communication life were associated to varying degrees with the construct of communicative participation as measured by social network size. Conclusion Assessment of these variables, along with early identification of cognitive decline, could play an important role in identifying elderly individuals at risk for limitations in communicative participation and associated consequences.

The Communicative Participation Item Bank: Evaluating, and Reevaluating, Its Use across Communication Disorders in Adults

Patient-reported outcomes (PROs) are essential in patient-centered, evidence-based practice in speech-language pathology. PROs respect individuals who live with communication disorders as key stakeholders providing a critically unique perspective on consequences of communication disorders, and whether interventions bring about meaningful changes. Some PROs focus on specific communication symptoms such as voice or language symptom severity, while others focus on broader constructs such as quality of life. Many PROs target specific diagnostic groups. This article presents the Communicative Participation Item Bank (CPIB), a PRO that measures communicative participation restrictions. The CPIB was based on the concept of participation, or engagement in life situations, as defined in the World Health Organization's International Classification of Functioning, Disability, and Health. It was designed to be relevant for adults across different communication disorders to facilitate clinical and research activities that may involve either comparing or aggregating data across communication disorders. The CPIB follows current PRO development protocols including systematic guidance from stakeholders through cognitive interviews, and the measurement methods of Item Response Theory that allow precise and adaptive assessment. This article reviews use of the CPIB across different diagnostic groups, and identifies needs for future efforts to expand the relevance of the CPIB further.

Predicting Communicative Participation in Adults Across Communication Disorders

Purpose The purpose of this study was to explore the extent to which communicative participation differs across diagnoses and if there are common predictor variables for communicative participation across diagnoses. Method Survey data on self-report variables including communicative participation were collected from 141 community-dwelling adults with communication disorders due to Parkinson's disease, cerebrovascular accident, spasmodic dysphonia, or vocal fold immobility (VFI). Analysis of covariance was used to determine communicative participation differences between diagnoses, with age, sex, and hearing status as covariates. Sequential entry linear regression was used to examine associations between communicative participation and variables representing a range of psychosocial constructs across diagnoses. Results The VFI group had the least favorable communicative participation differing significantly from Parkinson's disease and spasmodic dysphonia groups. Self-rated speech/voice severity, self-rated effort, mental health, perceived social support, and resilience contributed to variance in communicative participation when pooled across diagnoses. The relationship between communicative participation and the variables of effort and resilience differed significantly when diagnosis was considered. Conclusions The findings suggest that communicative participation restrictions may vary across some diagnoses but not others. People with VFI appear to differ from other diagnosis groups in the extent of participation restrictions. Effort and resilience may play different roles in contributing to communicative participation in different disorders, but constructs such as social support, severity, and mental health appear to have consistent relationships with communicative participation across diagnoses. The findings can help clinicians identify psychosocial factors beyond the impairment that impact clients' communication in daily situations.

Perceptual and Acoustic Effects of Dual-Focus Speech Treatment in Children With Dysarthria

Purpose Children with dysarthria secondary to cerebral palsy may experience reduced speech intelligibility and diminished communicative participation. However, minimal research has been conducted examining the outcomes of behavioral speech treatments in this population. This study examined the effect of Speech Intelligibility Treatment (SIT), a dual-focus speech treatment targeting increased articulatory excursion and vocal intensity, on intelligibility of narrative speech, speech acoustics, and communicative participation in children with dysarthria. Method American English–speaking children with dysarthria ( n = 17) received SIT in a 3-week summer camplike setting at Columbia University. SIT follows motor-learning principles to train the child-friendly, dual-focus strategy, “Speak with your big mouth and strong voice.” Children produced a story narrative at baseline, immediate posttreatment (POST), and at 6-week follow-up (FUP). Outcomes were examined via blinded listener ratings of ease of understanding ( n = 108 adult listeners), acoustic analyses, and questionnaires focused on communicative participation. Results SIT resulted in significant increases in ease of understanding at POST, that were maintained at FUP. There were no significant changes to vocal intensity, speech rate, or vowel spectral characteristics, with the exception of an increase in second formant difference between vowels following SIT. Significantly enhanced communicative participation was evident at POST and FUP. Considerable variability in response to SIT was observed between children . Conclusions Dual-focus treatment shows promise for improving intelligibility and communicative participation in children with dysarthria, although responses to treatment vary considerably across children. Possible mechanisms underlying the intelligibility gains, enhanced communicative participation, and variability in treatment effects are discussed.
