Communicative Participation in Dysarthria: Perspectives for Management

Communicative participation is restricted in many conditions associated with dysarthria. This position paper defines and describes the construct of communicative participation. In it, the emergence of this construct is reviewed, along with the predictors of and variables associated with communicative participation in the dysarthrias. In doing so, the features that make communicative participation unique and distinct from other measures of dysarthria are highlighted, through emphasizing how communicative participation cannot be predicted solely from other components of the World Health Organization’s International Classification of Functioning, Disability and Health (ICF), including levels of impairment or activity limitations. Next, the empirical literature related to the measurement of communicative participation and how this research relates to dysarthria management is presented. Finally, the development of robust clinical measures of communicative participation and approaches to management is described from the point of view of the clinician. We argue that communicative participation should be a primary focus of treatment planning and intervention to provide patient-centered, holistic, and value-based clinical interventions which are responsive to the needs of individuals living with dysarthria.

Older adults' perceptions of current and future hearing healthcare services in Australia, England, US and Canada

OBJECTIVE

A high prevalence of hearing loss in older adults contrasts with a small proportion of people who seek help. Emerging developments in hearing healthcare (HHC) could reduce costs but may not increase access. This study evaluated older adults' perceptions of current and future HHC services in Australia, England, US and Canada to explore potential levers and system improvements.

METHODS

Semi-structured focus groups (n = 47) were conducted, and data were analysed using a directed content analysis. Participants were adults 60 years and older with a) no hearing problems; b) hearing problems and hearing aid use; and c) hearing problems and no hearing aid use.

RESULTS

Perceived barriers, facilitators and preferences were largely consistent across countries, with stigma and trust in HHC being the barriers most often discussed.

CONCLUSION

Although cost and access were consistently deemed important, there may be limited change in help-seeking and HHC uptake unless the key barriers of trust and stigma are addressed. When seeking to undertake transformative change to healthcare it is important to engage recipients of care to understand existing barriers and coproduce a user-centered solution.

The best possible start: A qualitative study on the experiences of parents of young children with or at risk for fetal alcohol spectrum disorders

BACKGROUND

The developmental outcomes and life course trajectories of young children with or at-risk for fetal alcohol spectrum disorders (FASD) can be optimized when individual and family needs are identified early and met with family-centered early intervention (EI) services. However, little is known about access to and quality of EI services with this high-needs population.

METHOD

Twenty-five biological or adoptive parents of children with or at high risk for FASD, living in the greater area of Seattle, Washington participated in this qualitative study. Three focus groups were conducted using a semi-structured interview guide. Participants described their experience with EI, as well as other supports and challenges faced in their child's first three years of life. Interviews were audio recorded, transcribed verbatim and coded using phenomenological methods. Themes that were consistent across participant groups emerged from the data, as well as themes that showed differences among participant experiences.

RESULTS

Common EI supports and needs between biological and adoptive parent groups were identified. In addition, perspectives and needs unique to each parent group were revealed. Themes were identified and organized into three categories: (1) child needs; (2) parent needs and priorities; and (3) EI capacity. When parents talked about their child's cognitive, physical, communication or adaptive development, they all discussed how EI was meeting those needs. In contrast, when parents expressed concern for their child's social-emotional development, a description of how EI was supporting these needs was missing from the conversation. Parents appreciated when EI providers were truthful, provided anticipatory guidance, and connected them with supports for their own social-emotional well-being. Yet there were unmet needs for respite care, and parents expressed that support for basic needs related to child or family survival was not consistently recognized as a top priority for families. This high-risk group of young children and their parents also encountered a multitude of transitions in their child's early years and later. Parents wanted more support navigating these transitions as they entered or moved through different systems of care.

CONCLUSIONS

Parents appreciated and endorsed the importance of EI with its provision of individualized, family-centered supports and resources. Examination of the gaps and unmet needs that are common and distinct underscore the importance of an FASD-informed approach to EI. Study findings provide insight into areas for which EI enhancements could be developed in order to tailor supports for the complex needs of this diverse population of children and parents.

The Consequences of Oromandibular Dystonia on Communicative Participation: A Qualitative Study of the Insider's Experiences

Purpose The purpose of this study was to obtain a self-reported account of the experience of living with oromandibular dystonia (OMD) to gain a better understanding of both the daily facilitators and barriers to communicative participation and the strategies used for adapting to life with OMD. Method Eight individuals with OMD and dysarthria participated in 1 face-to-face, semistructured interview. Interviews were audio-recorded and transcribed verbatim. Qualitative, phenomenological methods of coding, immersion, and emergence were used in the analysis of interview data. Results Three major themes and 7 subthemes emerged from the analysis of interview data. First, "speaking is different now" provided examples of how speech changes are manifested in various life situations. Second, "my roles have changed" addressed how OMD has impacted work, home, and social roles. Third, "I accept it and move on" involved finding strategies that help and adopting a different perspective. Conclusion We suggest that the management of OMD must take a more holistic approach by addressing consequences beyond the physical symptoms and be tailored to each individual based on his or her personal concerns and goals.

Experiences of Speaking With Noninvasive Positive Pressure Ventilation: A Qualitative Investigation

Purpose The aim of this study was to describe experiences of speaking with 2 forms of noninvasive positive pressure ventilation (NPPV)-mouthpiece NPPV (M-NPPV) and nasal bilevel positive airway pressure (BPAP)-in people with neuromuscular disorders who depend on NPPV for survival. Method Twelve participants (ages 22-68 years; 10 men, 2 women) with neuromuscular disorders (9 Duchenne muscular dystrophy, 1 Becker muscular dystrophy, 1 postpolio syndrome, and 1 spinal cord injury) took part in semistructured interviews about their speech. All subjects used M-NPPV during the day, and all but 1 used BPAP at night for their ventilation needs. Interviews were audio-recorded, transcribed, and verified. A qualitative descriptive phenomenological approach was used to code and develop themes. Results Three major themes emerged from the interview data: (a) M-NPPV aids speaking (by increasing loudness, utterance duration, clarity, and speaking endurance), (b) M-NPPV interferes with the flow of speaking (due to the need to pause to take a breath, problems with mouthpiece placement, and difficulty in using speech recognition software), and (c) nasal BPAP interferes with speaking (by causing abnormal nasal resonance, muffled speech, mask discomfort, and difficulty in coordinating speaking with ventilator-delivered inspirations). Conclusion These qualitative data from chronic NPPV users suggest that both M-NPPV and nasal BPAP may interfere with speaking but that speech is usually better and speaking is usually easier with M-NPPV. These findings can be explained primarily by the nature of the 2 ventilator delivery systems and their interfaces.

The Relationship Between Non-Orthographic Language Abilities and Reading Performance in Chronic Aphasia: An Exploration of the Primary Systems Hypothesis

PURPOSE

This study investigated the relationship between non-orthographic language abilities and reading in order to examine assumptions of the primary systems hypothesis and further our understanding of language processing poststroke.

METHOD

Performance on non-orthographic semantic, phonologic, and syntactic tasks, as well as oral reading and reading comprehension tasks, was assessed in 43 individuals with aphasia. Correlation and regression analyses were conducted to determine the relationship between these measures. In addition, analyses of variance examined differences within and between reading groups (within normal limits, phonological, deep, or global alexia).

RESULTS

Results showed that non-orthographic language abilities were significantly related to reading abilities. Semantics was most predictive of regular and irregular word reading, whereas phonology was most predictive of pseudohomophone and nonword reading. Written word and paragraph comprehension were primarily supported by semantics, whereas written sentence comprehension was related to semantic, phonologic, and syntactic performance. Finally, severity of alexia was found to reflect severity of semantic and phonologic impairment.

CONCLUSIONS

Findings support the primary systems view of language by showing that non-orthographic language abilities and reading abilities are closely linked. This preliminary work requires replication and extension; however, current results highlight the importance of routine, integrated assessment and treatment of spoken and written language in aphasia.

Scoping review of common secondary conditions after stroke and their associations with age and time post stroke

BACKGROUND

Health care providers need to be alert to secondary conditions that might develop after stroke so that these conditions can be prevented or treated early to reduce further deterioration of health and quality of life.

OBJECTIVES

To review and describe the prevalence of secondary conditions after stroke and to summarize associations between secondary conditions and age and time post stroke.

METHODS

A scoping review of studies pertaining to secondary conditions after stroke published between 1986 and 2011 was conducted.

RESULTS

Seventy-six articles provided information regarding 6 secondary conditions: depression, pain, falls, fatigue, bowel/bladder problems, and sleep difficulties. Prevalence varied widely across studies for each condition. The limited repeated-measures evidence suggests that secondary conditions tend to occur in the first weeks or months post stroke and may remain relatively stable over time. Other evidence from regression analyses suggests either no significant associations between time post stroke or age or mixed results. Secondary conditions appear to be most commonly associated with severity of impairments.

CONCLUSIONS

Health care providers need to be alert to the development of secondary conditions after stroke in individuals as they age as well as in the poststroke time span. Obtaining a clear understanding of the prevalence of secondary conditions and associations with age and time post stroke is difficult because of variations in research methodologies. Future research is needed to define secondary condition prevalence and risk factors more clearly and to identify interventions that could reduce the prevalence and impact of these conditions on quality of life.

Growing Older With a Physical Disability: A Special Application of the Successful Aging Paradigm

Objectives

In the United States, the average age of people living with early-acquired physical disabilities is increasing. This cohort is said to be aging with disability and represents a unique population among older adults. Given recent policy efforts designed to merge aging and disability services, it is critical that models of "successful aging" include and are relevant to this population. However, many current definitions of successful aging emphasize avoidance of disability and high levels of physical function as necessary to well-being.

Method

In 9 focus groups, we examined perspectives of "successful aging" in 49 middle-aged and older individuals living with spinal cord injury, multiple sclerosis, muscular dystrophy, or postpolio syndrome. Transcripts were analyzed using a structured qualitative coding approach and Dedoose indexing software.

Results

Participants ranged in age from 45 to 80 years (M = 62) and had lived with their disability diagnosis for an average of 21 years. Analysis revealed 4 primary themes of successful aging: resilience/adaptation, autonomy, social connectedness, and physical health (including access to general and specialty healthcare).

Discussion

Results highlight the need for a nuanced application of the "successful aging" paradigm in this population.

Exploring the Relevance of Items in the Communicative Participation Item Bank (CPIB) for Individuals With Hearing Loss

PURPOSE

The Communicative Participation Item Bank (CPIB) was developed to evaluate participation restrictions in communication situations for individuals with speech and language disorders. This study evaluated the potential relevance of CPIB items for individuals with hearing loss.

METHOD

Cognitive interviews were conducted with 17 adults with a range of treated and untreated hearing loss, who responded to 46 items. Interviews were continued until saturation was reached and prevalent trends emerged. A focus group was also conducted with 3 experienced audiologists to seek their views on the CPIB. Analysis of data included qualitative and quantitative approaches.

RESULTS

The majority of the items were applicable to individuals with hearing loss; however, 12 items were identified as potentially not relevant. This was largely attributed to the items' focus on speech production rather than hearing. The results from the focus group were in agreement for a majority of items.

CONCLUSIONS

The next step in validating the CPIB for individuals with hearing loss is a psychometric analysis on a large sample. Possible outcomes could be that the CPIB is considered valid in its entirety or the creation of a new questionnaire or a hearing loss-specific short form with a subset of items is necessary.

Addressing Communicative Participation in Treatment Planning for Adults: A Survey of U.S. Speech-Language Pathologists

PURPOSE

In speech-language pathology, there is increasing attention on participation-focused interventions to optimize participation in valued life roles. The purpose of this study was to investigate how speech-language pathologists (SLPs) in the United States address life participation in therapy programs, as well as their opinions regarding barriers and facilitators to participation-focused intervention.

METHOD

An online questionnaire presented case scenarios for aphasia, dysarthria, and laryngectomy to 66 SLPs who have worked with adults. SLPs were asked to write goals and describe therapy activities for the scenarios. The final section of the questionnaire was an open-ended question regarding barriers and facilitators to participation-focused intervention.

RESULTS

Many SLPs addressed participation in their rationales for therapy; 50% of goals had a participation-focused rationale. However, the goals, activities, and outcomes measures typically focused more on impairment and skill performance. Only 8% of goals specifically referenced participation. Although many SLPs stated that participation-focused intervention is important, they identified many barriers to implementation including time and productivity constraints, limits of clinical settings, and documentation challenges.

CONCLUSIONS

There is potential for gaps between SLPs' participation-focused rationale for therapy and activities or outcomes measures that often do not include participation elements. SLPs are interested in participation-focused treatment resources.

The relationship between communicative participation and postlaryngectomy speech outcomes

BACKGROUND

The purpose of this study was to examine relationships between communicative participation and postlaryngectomy speech outcomes, including listener-rated speech intelligibility and acceptability, and patient-rated speech acceptability and voice handicap.

METHODS

Thirty-six laryngectomized individuals completed the Communicative Participation Item Bank (CPIB) short form and the Voice Handicap Index-10 (VHI-10). They provided recordings from the Sentence Intelligibility Test (SIT) and a reading passage, and rated their own speech acceptability. Forty-eight inexperienced listeners transcribed the SIT sentences to derive intelligibility scores. Eighteen additional listeners judged the speech acceptability using the rating scales.

RESULTS

Listeners judged tracheoesophageal speakers as significantly more intelligible and acceptable than electrolaryngeal speakers (p < .05). Speech acceptability was significantly more acceptable to speakers than listeners (p < .05). Weak, nonsignificant relationships were found between communicative participation and listener-rated outcomes. Stronger, significant relationships were found between communicative participation and self-rated speech acceptability and voice handicap (p < .05).

CONCLUSION

Patient-reported communication outcomes are complementary to listener-rated outcomes. © 2015 Wiley Periodicals, Inc. Head Neck 38: E1955-E1961, 2016.

Communicative participation restrictions in multiple sclerosis: associated variables and correlation with social functioning

Individuals with multiple sclerosis (MS) are at risk for communication problems that may restrict their ability to take participation in important life roles such as maintenance of relationships, work, or household management. The aim of this project is to examine selected demographic and symptom-related variables that may contribute to participation restrictions. This examination is intended to aid clinicians in predicting who might be at risk for such restrictions and what variables may be targeted in interventions. Community-dwelling adults with MS (n=216) completed a survey either online or using paper forms. The survey included the 46-item version of the Communicative Participation Item Bank, demographics (age, sex, living situation, employment status, education, and time since onset of diagnosis of MS), and self-reported symptom-related variables (physical activity, emotional problems, fatigue, pain, speech severity, and cognitive/communication skills). In order to identify predictors of restrictions in communicative participation, these variables were entered into a backwards stepwise multiple linear regression analysis. Five variables (cognitive/communication skills, speech severity, speech usage, physical activity, and education) were statistically significant predictors of communication participation. In order to examine the relationship of communicative participation and social role variables, bivariate Spearman correlations were conducted. Results suggest only a fair to moderate relationship between communicative participation and measures of social roles. Communicative participation is a complex construct associated with a number of self-reported variables. Clinicians should be alert to risk factors for reduced communicative participation including reduced cognitive and speech skills, lower levels of speech usage, limitations in physical activities and higher levels of education.

LEARNING OUTCOMES

The reader will be able to: (a) describe the factors that may restrict participation in individuals with multiple sclerosis; (b) list measures of social functioning that may be pertinent in adults with multiple sclerosis; (c) discuss factors that can be used to predict communicative participation in multiple sclerosis.

Communicative participation and quality of life in head and neck cancer

OBJECTIVE

The purpose of this study was to determine how a new self-report outcome measure of communicative participation, the Communicative Participation Item Bank (CPIB), related to disease- and discipline-specific quality of life (QOL) outcomes in a head and neck cancer (HNC) population.

METHODS

One hundred ninety-five individuals treated for HNC completed the CPIB, the University of Washington Quality of Life questionnaire (UW-QOL), and the Voice Handicap Index-10 (VHI-10).

RESULTS

Results revealed moderate QOL scores across the UW-QOL (mean scores: global QOL = 66; physical subscale = 70; social-emotional subscale = 73) and VHI-10 (mean = 16). Correlations between the CPIB and the UW-QOL scores were statistically significant (P < .001) but relatively weak (r = .37-.38). As hypothesized, a stronger correlation was found between the CPIB and the VHI-10 (r = -0.79; P < .001).

CONCLUSION

Clinicians may consider adopting the CPIB to complement existing tools in assessing communication outcomes after HNC.

Associations between laryngeal and cough dysfunction in motor neuron disease with bulbar involvement

True vocal fold (TVF) dysfunction may lead to cough ineffectiveness. In individuals with motor neuron disease (MND), cough impairment in the context of dysphagia increases risk for aspiration and respiratory failure. This study characterizes differences and associations between TVF kinematics and airflow during cough in individuals with bulbar MND. Sequential glottal angles associated with TVF movements during volitional cough were analyzed from laryngeal video endoscopy examinations of adults with bulbar MND (n = 12) and healthy controls (n = 12) and compared with simultaneously collected cough-related airflow measures. Significant group differences were observed with airflow and TVF measures: volume acceleration (p ≤ 0.001) and post-compression abduction TVF angle average velocity (p = 0.002) were lower and expiratory phase rise time (p = 0.001) was higher in the MND group. Reductions in maximum TVF angle during post-compression abduction in the MND group approached significance (p = 0.09). All subjects demonstrated complete TVF and supraglottic closure during the compression phase of cough, except for incomplete supraglottic closure in 2/12 MND participants. A strong positive relationship between post-compression maximum TVF abduction angle and peak expiratory cough flow was observed in the MND group, though it was not statistically significant (r = 0.55; p = 0.098). Reductions in the speed and extent of TVF abduction are seen during the expulsion phase of cough in individuals with MND. This may contribute to cough impairment and morbidity.

Communication support through multimodal supplementation: a scoping review

Speech supplementation strategies improve spoken communication for people with motor speech disorders who experience reduced speech intelligibility. The purpose of this review was to summarize the literature on traditional supplementation strategies (e.g., alphabet supplementation, topic supplementation, and gestural supplementation) and to expand the definition of speech supplementation to include additional modalities, such as augmenting speech with pictures via mobile technology, and conversation management strategies. Results showed that studies of traditional supplementation consistently reported positive outcomes, including increased intelligibility, decreased speech rate, and positive attitudes toward speakers. New modalities, such as supplementing speech through digital photos, may come to be integrated with traditional approaches, given the proliferation of digital photography and mobile tablet technologies. In addition, new research is exploring the role of communication partners in dyads where one speaker has dysarthria, as well as strategies that communication partners employ to understand dysarthric speech.

Perspectives on self-management in multiple sclerosis: a focus group study

The aim of this study was to elucidate the experience of self-management among people with multiple sclerosis (MS) and gather their input to inform a self-management intervention. Twelve people with MS participated in focus groups in which they were asked open-ended questions about MS symptoms, challenges, overcoming challenges, symptom management, and treatment preferences. The results suggest four major themes: 1) "The Everyday Experience of MS," including comments about symptoms and their impact on functioning; 2) "Motivation for Self-Management," including descriptions of motivation originating from physical necessity, success with other management techniques, and external sources; 3) "Coping Strategies and Skills," including descriptions of changing behaviors, expanding social support networks, finding resources, utilizing medical treatment, and monitoring symptoms; and 4) "Vision for a Self-Management Intervention," including suggestions that an intervention be individualized, be motivating, and provide resources. The results of this study can inform the design and implementation of self-management interventions. Experiences described by participants are consistent with other qualitative reports suggesting the active role people with MS play in managing their condition. Intervention approaches must consider the complex constellation of symptoms associated with MS and provide individualized treatments that enhance the person's ability to manage their symptoms, barriers presented by such symptoms, and their health care.

Modeling Secondary Health Conditions in Adults Aging With Physical Disability

Objectives: To test a conceptual model of secondary health conditions, age, and function in persons aging with long-term physical disabilities. Methods: Surveys were collected from 1,862 adults with spinal cord injury, neuromuscular disease, multiple sclerosis, or post-polio syndrome. Structural equation modeling was used to build a model describing relationships among physical and psychosocial secondary health conditions, pain, functional impairments, chronic medical conditions, and age. Results: In total, 12 individual symptom or function domains (latent factors) were identified, grouped into 5 broader factors. Increasing age was associated with greater rates of physical and health problems and poorer function, and showed curvilinear relationships with pain and psychosocial difficulties. Discussion: These data support a biopsychosocial model of secondary health conditions in adults aging with physical disability and suggest a five-factor approach for conceptualizing secondary conditions and their impact. Results also emphasize the importance of age in symptom severity and impact.

Social support, depression, and physical disability: age and diagnostic group effects

BACKGROUND

Social support is an important resource that may benefit individuals aging with physical disabilities, although its effects may vary depending on age, sex, and type of disability.

OBJECTIVES

To (1) examine differences in social support--and how support might vary as a function of age and sex--in samples of individuals with multiple sclerosis (MS), spinal cord injury (SCI), and muscular dystrophy (MD) and (2) understand the extent that associations between different support domains and depression might be moderated by disability diagnosis, sex and age.

METHODS

A convenience sample (N = 1416) of individuals with MS, SCI, and MD completed surveys that included measures of perceived social support and depressive symptoms.

RESULTS

No significant support differences were found between diagnostic groups. There was a gradual decrease in social support with chronological age, and women reported more support than men, particularly friend support. Levels of perceived friend support were negatively associated with depression, and the associations between social support and depression did not differ as a function of age, sex, or diagnosis.

CONCLUSIONS

Social support is similarly associated with lower levels of depression for men and women, across disability diagnoses and all ages. Being a man and being older may be associated with lower levels of perceived support. Research is needed to determine if interventions that improve support will decrease depression and improve quality of life in persons with disabilities, particularly for men and individuals who are aging.

Endoscopic assessment of vocal fold movements during cough

OBJECTIVES

Little is known about the function of the true vocal folds (TVFs) during cough. The objective of this study was to determine the reliability of measuring TVF movements during cough and to obtain preliminary normative data for these measures.

METHODS

Sequential glottal angles associated with TVF adduction and abduction across the phases of cough were analyzed from laryngeal videoendoscopy records of 38 young healthy individuals.

RESULTS

The intraobserver and interobserver reliability of 3 experienced measurers was high (intraclass correlation of at least 0.97) for measuring sequential and maximum glottal angles. The TVF abduction velocity during expulsion was significantly higher than the precompression adduction velocity (p = 0.002), but there were no significant differences in maximum angle. No statistically significant differences were seen in maximum TVF angle and velocity when they were compared between the sexes and between the levels of cough strength. True vocal fold closure following expulsion occurred in 42% of soft coughs and in 57% of moderate to hard coughs.

CONCLUSIONS

The TVF abduction angles during cough can be reliably measured from laryngeal videoendoscopy in young healthy individuals. The TVF movements are faster for expulsion abduction than for precompression adduction, but the extents of abduction are similar. To validly determine the cough phase duration, simultaneous measures of airflow are needed.

Satisfaction with participation in multiple sclerosis and spinal cord injury

PURPOSE

To validate a single item self-report of satisfaction with participation in two groups with differing patterns of symptoms and disease progress, multiple sclerosis (MS) and spinal cord injury (SCI).

METHOD

Community-dwelling adults with MS (N = 1,271) or SCI (N = 620) completed a battery of self-report questionnaires covering demographic information, disease specific measures, symptoms, psychological distress, social-environmental issues, and overall well-being. They were also asked to rate satisfaction with participation: How satisfied are you with your ability to take part in activities that are important to you: not satisfied, somewhat satisfied, satisfied, or very satisfied. Kendall's tau rank correlation coefficient and χ(2) tests were used to examine the strength and direction of associations between demographic and symptom variables and responses to the participation item.

RESULTS

Although the demographics of the MS and SCI differed in predictable ways, younger participants and those employed report more satisfaction with participation. Ratings of satisfaction with participation were also consistently associated with a number of variables including less fatigue, pain, depression, stress, anxiety, as well as higher overall measures of well-being across the two populations.

CONCLUSIONS

More research is needed to better understand the multiple dimensions that comprise participation and to develop robust and sensitive measurement tools. A global rating of satisfaction with participation using one item has a number of potentially useful applications including description of case mix in clinical trials.

Pathways of change experienced by people aging with disability: a focus group study

PURPOSE

To examine the issues related to aging with disability from the perspective of the person with the disabilities.

METHOD

Twelve community-dwelling adults with spinal cord injury (SCI), post-polio syndrome (PPS) or multiple sclerosis (MS) participated in focus groups where they were asked open-ended questions about changes related to aging with disability, accommodations made and perspectives on the future.

RESULTS

Results of qualitative analysis suggested five major themes related to aging with a disability: (1) Participant identity, including comments about how participants described themselves and their lives with a long-standing disability; (2) Physical pathways including comments about the progression of physical symptoms; (3) Psychosocial pathways, including descriptions of adaptations to disability, the development of emotional well-being and strategies to deal with disability; (4) Changing health care, reflecting improvement noted over time in health care services; and (5) Concerns about the future, including comments reflecting participant uncertainty about the potential course of disability.

CONCLUSIONS

The process of aging with disability was characterised by multiple pathways. Some, including positive psychosocial adjustment and medical advancements, were favourable, while others, including physical decline, were not. The co-existence of high quality of life in the presence of physical decline is consistent with a larger literature in older adults, and future research should focus on identifying aging factors that may contribute to the buffering the psychological impact of physical decline.

Being in- or out-of-sync: couples' adaptation to change in multiple sclerosis

PURPOSE

To examine how couples adapt to the challenges of multiple sclerosis (MS) and to identify possible risk factors for relational stress.

METHOD

Semi-structured interviews were conducted with eight couples to explore how participants defined and identified the strengths and challenges in their relationship, negotiated role changes and received external support. Conceptual frameworks on how families adapt to chronic illness guided within and across case analyses. We identified patterns in the couples' current responses to the demands and stressors of MS.

RESULTS

Two patterns of adaptation to MS were identified as being 'in-sync' or 'out-of-sync'. Characteristics of the four couples currently in-sync included having a relapsing-remitting type of MS, which proceeded at a pace that enabled both partners to maintain their social roles and identity, and a collaborative problem solving style. The four couples currently out-of-sync had a rapid progression of MS, loss of employment before retirement age, differences in personal styles that shifted from being complementary to oppositional in the face of increased demands and struggles with parenting adolescent children.

CONCLUSIONS

Clinicians can use these data to assess possible relational strain in couples with MS and identify families who might benefit from referrals to family therapy or other relational support.

Developing the communicative participation item bank: Rasch analysis results from a spasmodic dysphonia sample

PURPOSE

The purpose of this study was to conduct the initial psychometric analyses of the Communicative Participation Item Bank-a new self-report instrument designed to measure the extent to which communication disorders interfere with communicative participation. This item bank is intended for community-dwelling adults across a range of communication disorders.

METHOD

A set of 141 candidate items was administered to 208 adults with spasmodic dysphonia. Participants rated the extent to which their condition interfered with participation in various speaking communication situations. Questionnaires were administered online or in a paper version per participant preference. Participants also completed the Voice Handicap Index (B. H. Jacobson et al., 1997) and a demographic questionnaire. Rasch analyses were conducted using Winsteps software (J. M. Linacre, 1991).

RESULTS

The results show that items functioned better when the 5-category response format was recoded to a 4-category format. After removing 8 items that did not fit the Rasch model, the remaining 133 items demonstrated strong evidence of sufficient unidimensionality, with the model accounting for 89.3% of variance. Item location values ranged from -2.73 to 2.20 logits.

CONCLUSIONS

Preliminary Rasch analyses of the Communicative Participation Item Bank show strong psychometric properties. Further testing in populations with other communication disorders is needed.

Use of cognitive aids and other assistive technology by individuals with multiple sclerosis

PURPOSE

To investigate the use of assistive technology (AT), unmet needs for AT, and examine correlates of use of memory aids and cognitive strategies among individuals with multiple sclerosis (MS).

METHOD

A cross-sectional study of 1,063 community dwelling adults with MS in Washington State. A self-report survey assessed use of AT as well as depression, fatigue, mobility, and other demographic and disease related variables.

RESULTS

Some 70% of respondents reported using memory strategies and 50.7% reported using electronic memory aids. The strongest correlate of use of electronic memory aids was endorsement of difficulties thinking (OR: 2.09, p < 0.001) though younger age, higher education, and report of higher fatigue were also significant. Fatigue (OR: 1.27, p < 0.001) and depression (OR: 0.89, p < 0.001) were highly associated with use of memory strategies. Subjects who were older, unemployed, more depressed, and have more mobility disability were less likely to use memory strategies.

CONCLUSIONS

Use of AT for memory is widespread and further research should be conducted on efficacy of AT. Many individuals who might be presumed to need AT for memory most (older, less educated, more disability) are least likely to report use. Healthcare providers are urged to ask about memory AT and make appropriate referrals.

A longitudinal evaluation of persons with disabilities: does a longitudinal definition help define who receives necessary care?

OBJECTIVE

To assess, using a longitudinal definition, the impact of disability on a broad range of objective health care quality indicators.

DESIGN

Longitudinal cohort study following up with patients over several years. The first 2 interviews, 1 year apart, were used to determine each patient's disability status in activities of daily living (ADLs). Assessment of the health care indicators commenced after the second interview and continued throughout the survey period (an additional 1-3y).

SETTING

National survey.

PARTICIPANTS

Participants (N=29,074) of the Medicare Current Beneficiary Survey (1992-2001) with no, increasing, decreasing, and stable ADL disability.

INTERVENTIONS

Not applicable.

MAIN OUTCOME MEASURE

The incidence of 5 avoidable outcomes, receipt of 3 preventive care measures, and adherence to 32 diagnostically based indicators assessing the quality of treatment for acute myocardial infarction [AMI], angina, breast cancer, cerebrovascular accident, transient ischemic attack, cholelithiasis, chronic obstructive pulmonary disease [COPD], congestive heart failure, depression, gastrointestinal bleeding, diabetes, and hypertension.

RESULTS

For most indicators, less than 75% of eligible patients received necessary care, regardless of disability status. For 5 indicators, less than 50% of patients received appropriate treatment. In a logistic regression analysis that controlled for patient age, sex, race, and income, disability status was a significant factor in 7 quality measures (AMI, breast cancer, COPD, diabetes, angina, pneumonia, annual visits).

CONCLUSIONS

Using a longitudinal definition of disability and objective health quality indicators, we found that disability status can be an important factor in determining receipt of quality health care in a broad range of diagnostic categories. However, the impact of disability status varies depending on the indicator measured. In this cohort of patients, the changing nature of a person's disability seems to have less impact than whether they ever have had any functional deficits.

Measuring participation in people living with multiple sclerosis: a comparison of self-reported frequency, importance and self-efficacy

PURPOSE

To compare three dimensions related to participation in everyday situations in community-dwelling adults with multiple sclerosis (MS).

METHODS

Mail survey was obtained from 112 respondents. Data were analyzed using Kendall's tau-b correlation coefficients between responses to participation items relative to three question dimensions (importance, frequency, and self-efficacy) and criterion variables (mobility, depression, general health, fatigue and pain).

RESULTS

No significant associations were found between item responses in the importance dimension and the criterion variables. Weak associations were found for items in the frequency dimension, and stronger associations were found for items in the self-efficacy dimension.

CONCLUSIONS

Different dimensions of participation in specific life situations yielded different responses and associations of those responses with key criterion measures. Subjective importance of participating in everyday situations is relatively independent of measures of mobility, general health, depression, fatigue and pain. Subjective judgments of self-efficacy for participation are more closely linked to these criterion measures. Caution is warranted when interpreting scales of participation because participation is a complex construct, potentially composed of several dimensions.

Minority disparities in disability between Medicare beneficiaries

OBJECTIVES

To examine racial and ethnic disparities in mobility limitation, activities of daily living (ADLs), and instrumental activities of daily living (IADLs) in older adults enrolled in Medicare.

DESIGN

Longitudinal national survey.

PARTICIPANTS

Community-dwelling respondents in the Medicare Current Beneficiaries Survey from 1992 to 2004 (10,180-16,788 respondents per year).

MEASUREMENTS

Disability-related outcomes included mobility limitation, difficulty in six ADLs and six IADLs. Explanatory variables included age, sex, racial or ethnic group, living situation, and income level.

RESULTS

From 1992 to 2004, proportions of Medicare beneficiaries with mobility limitations were stable across racial and ethnic groups, improving slightly for ADLs and IADLs. Blacks reported more limitations in all three disability-related measures. In a longitudinal analysis, the probability of developing mobility limitation was consistently higher for blacks, followed by white Hispanics, white non-Hispanics, and Asians, after adjusting for age, sex, socioeconomic status, and living situation. For ADL and IADL difficulties, the number of reported difficulties increased with age for all ethnic and racial groups. At approximately age 75, Asians and white Hispanics reported difficulties with much higher numbers of ADLs and IADLs than the other groups.

CONCLUSION

Across all ethnic and racial groups, self-reported disability has declined in the past decade, but even after adjusting for age, sex, socioeconomic status, and living situation, racial and ethnic disparities in disability outcomes persist. Race and ethnicity may influence the reporting of disability, potentially affecting measures of prevalence. Further research is needed to understand whether these differences are a result of perceptions related to disablement or true differences in disability between racial and ethnic groups.

Satisfaction with communicative participation as defined by adults with multiple sclerosis: a qualitative study

PURPOSE

This study examined satisfaction with communicative participation as reported by adults with multiple sclerosis (MS).

METHOD

Eight community-dwelling adults with MS participated in semi-structured interviews. They were asked to discuss their satisfaction with their communication in a variety of situations. Interviews were analyzed using a constant comparative method of qualitative description.

RESULTS

Themes derived included: Comfort, consisting of Ease and Confidence; Success of the Outcome, including Function is Achieved and A Connection is Made; and Personal Meaning of Participation, including Personal Preferences, Comparison with the Past, and Thinking about One's Own Communication.

CONCLUSIONS

Participants described multiple facets of satisfaction with communicative participation. Some of the dimensions were similar to those in existing assessment instruments such as levels of ease or difficulty with performance. Participants did not talk about frequency of activities as a key part of their satisfaction. Implications for identifying intervention targets and treatment outcome measurements are provided.

LEARNING OUTCOMES

The reader should be able to: 1) define communicative participation and identify key elements of this construct; 2) identify the issues that were most relevant to satisfaction with communicative participation with participants with MS; and 3) identify reasons for greater emphasis on the subjective viewpoint of people with communication disorders in measurement of treatment outcomes.

Association of mobility limitations with health care satisfaction and use of preventive care: a survey of Medicare beneficiaries

OBJECTIVE

To examine the association between satisfaction with health care, the use of preventive health care, and mobility limitation.

DESIGN

Cross-sectional analysis of survey data.

SETTING

Community.

PARTICIPANTS

A total of 12,769 people, age greater than 65, who participated in the 2001 Medicare Current Beneficiary Survey.

INTERVENTIONS

Not applicable.

MAIN OUTCOME MEASURES

Self-report of mobility limitation, satisfaction, and use of preventive health care (immunizations, cancer screening). Sampling weights were used in all analyses, including logistic regression for survey data, to calculate estimates for a Medicare population of 31 million.

RESULTS

After controlling for sociodemographic characteristics, Medicare beneficiaries with mobility limitations were significantly more dissatisfied with their health care compared with beneficiaries without mobility limitations. Receipt of preventive care did not differ for those with and without mobility limitation on some preventive services.

CONCLUSIONS

Mobility limitation is highly associated with dissatisfaction with health care among older adult beneficiaries. Although Medicare beneficiaries may receive similar rates of preventive care, those with mobility limitation may have more difficulty accessing services and be more dissatisfied with their health care in general.

The Degenerative Dysarthrias: A Window into Critical Clinical and Research Issues

Although diversity of symptoms and urgency of needs pose many challenges, management of the degenerative dysarthrias is a crucial aspect of clinical practice. The purpose of this article is to review current research literature on selected degenerative dysarthrias including those associated with Parkinson's disease, multiple sclerosis, and amyotrophic lateral sclerosis. These dysarthrias are prevalent yet represent distinct patterns of underlying neuropathology, symptoms, age of onset, and rate of progression. Literature searches including the period 1997-2006 yielded 148 different studies reporting data on communication issues related to dysarthria. By far the largest category of studies was that which provided a basic description of speech production including the neurophysiologic, acoustic, or perceptual properties of dysarthria. Other categories included management (assessment and treatment) and the psychosocial consequences of dysarthria. While the topic of management of degenerative dysarthria is a focused one, it provides a window into many issues critical to the field of communication disorders including fundamental properties of speech production, development of evidence-based treatment techniques, the staging of these techniques into an effective management sequence, and the psychosocial consequences of communication disorders along with techniques to maintain communicative participation in the face of degenerative conditions.

Measuring communicative participation: a review of self-report instruments in speech-language pathology

PURPOSE

To assess the adequacy of self-report instruments in speech-language pathology for measuring a construct called communicative participation.

METHOD

Six instruments were evaluated relative to (a) the construct measured, (b) the relevance of individual items to communicative participation, and (c) their psychometric properties.

RESULTS

No instrument exclusively measured communicative participation. Twenty-six percent (n = 34) of all items (N = 132) across the reviewed instruments were consistent with communicative participation. The majority (76%) of the 34 items were associated with general communication, while the remaining 24% of the items were associated with communication at work, during leisure, or for establishing relationships. Instruments varied relative to psychometric properties.

CONCLUSIONS

No existing self-report instruments in speech-language pathology were found to be solely dedicated to measuring communicative participation. Developing an instrument for measuring communicative participation is essential for meeting the requirements of our scope of practice.

The psychosocial consequences of BOTOX injections for spasmodic dysphonia: a qualitative study of patients' experiences

OBJECTIVES/HYPOTHESIS

The purpose of this study is to examine the psychosocial consequences of BOTOX (Allergan, Inc. Irvine, CA) treatment for spasmodic dysphonia (SD). This article also explores how patients judge the success of treatment and make decisions about future treatment based on psychosocial issues relevant to them.

STUDY DESIGN

This study follows the phenomenological tradition of qualitative inquiry in which the objective is to explore the lived experiences of a group of persons who share a common phenomenon, in this case receiving BOTOX injections for SD.

METHODS

Six adults with SD who had been receiving BOTOX injections on a long-term basis participated in face-to-face interviews. The interviews were recorded, transcribed, and analyzed according to phenomenological guidelines to identify consistent themes as well as differences among participants' experiences.

RESULTS

The results are summarized in three primary themes that suggest (1) participants' experiences vary over time based on changes in factors such as lifestyle and personal priorities; (2) BOTOX has multidimensional psychosocial implications in physical, personal, and social domains; and (3) participants individualize their treatment regimens, taking into consideration the burden of treatment, scheduling priorities, and other strategies to maximize the benefits of BOTOX.

CONCLUSIONS

Based on this study, suggestions are provided for future research into a psychosocial outcome measurement, including longitudinal evaluations that accommodate changing patient priorities over time; multidimensional evaluations that incorporate physical, personal, and social issues; evaluations that include a measure of the burden of treatment; and evaluations that support a shared decision-making model with the voice clinicians.

Understanding the Use of Weights in the Analysis of Data From Multistage Surveys

Understanding the use of weights in the analysis of data from multistage surveys. Large national surveys are powerful tools with which to examine a variety of important rehabilitation-related issues and are currently the only feasible method to study disability trends over time. Because it is impractical to draw simple random samples from the entire United States, national surveys, such as the Medicare Current Beneficiary Survey (MCBS), select random samples of subgroups of a population. Thus, respondents may have unequal probabilities of being included in the survey, and weighting must be used in the analysis before the results may be generalized to the entire United States. Surveys such as the MCBS are rich sources of data for rehabilitation medicine, and it can be expected that more research will be conducted using these data sources. Statistical analysis of these data should account for the sampling scheme used in data collection. We review the principles involved in the design of multistage samples, the calculation of weights, and their use in the data analysis, focusing on their importance in the estimation of population values. Our objective is to help readers to understand and interpret results of research articles using this methodology. Examples using the MCBS data are provided to clarify the concepts presented in the article.

Patient Perspectives on Disease-Modifying Therapy in Multiple Sclerosis

The purpose of this study was to understand factors contributing to the decision-making processes of individuals with multiple sclerosis (MS) regarding the use of disease-modifying therapy (DMT). Semi-structured qualitative interviews were conducted with 18 individuals with MS. Qualitative interviews revealed two major themes: opting for and opting out of DMT. Participants indicated that stable health, predictability, and perceived control were reasons to be on DMT. They also indicated that taking DMT is not without personal cost, both financial and psychological (eg, denial, fear, and uncertainty). Fear of needles and side effects, not feeling “sick enough,” the costs of medication versus benefits, and discouragement from physicians were given as reasons for opting out of DMT. Participants also reported that restarting DMT after they had stopped was difficult, especially if they felt better when not using DMT. Early treatment of MS with DMT, especially for those with relapsing-remitting MS, is strongly supported by published findings. Although participants in our study revealed significant barriers to initiating and adhering to DMT, recent advances in clinical practice and improved coverage for treatment costs should reduce these barriers.

The consequences of spasmodic dysphonia on communication-related quality of life: a qualitative study of the insider's experiences

The purpose of this study was to explore the biopsychosocial consequences of spasmodic dysphonia (SD) as experienced by people with SD. Qualitative research methods were used to investigate the insider's perspective of living with SD. Six adults with SD participated in face-to-face phenomenological interviews. The results are summarized in a model of personal experiences of SD which shows that communication-related quality of life (QOL) is shaped by experiences with multiple physiologic (voice quality, effort, voice dependability); personal (affective responses, changes in self-view, coping strategies) and social (physical environment, other people, participation in social roles) factors. Communication-related QOL is a complex and individualized construct with multidimensional contributors. This study suggests that understanding the nature of communication-related QOL for each individual requires exploration of each component of the model, exploration of the unique relationships among components for each person, and recognition of the multidimensional factors that shape the experience of SD.

LEARNING OUTCOMES

As a result of this activity the reader will be able to (1) identify general features of the phenomenological research method; (2) identify the three general categories of psychosocial consequences of SD; (3) identify those psychosocial consequences of SD that are under-represented in the literature; and (4) identify key conclusions of the communication-related quality of life model.

Effect of communication disability on satisfaction with health care: a survey of medicare beneficiaries

PURPOSE

To examine the prevalence and characteristics of community-dwelling Medicare beneficiaries reporting a communication disability and the relationship between that disability and dissatisfaction with medical care.

METHOD

A total of 12,769 Medicare Current Beneficiary Survey respondents age 65 and older in 2001 were categorized by level of communication disability. Sampling weights were used to make inferences about the entire Medicare population.

RESULTS

Over 16 million beneficiaries reported a communication disability. Hearing problems were most commonly reported (41.99%). The association between dissatisfaction and communication disability was statistically significant (p <or= .05) for 8 of 10 items.

CONCLUSIONS

Prevalence of dissatisfaction among those with a communication disability varied, ranging from 3.43% to 19.34%. Respondents with a communication disability reported much more dissatisfaction when compared with those respondents without a communication disability.

Mobility Limitations in the Medicare Population: Prevalence and Sociodemographic and Clinical Correlates

OBJECTIVES

To examine the prevalence of and clinical markers associated with mobility limitations in Medicare Current Beneficiary Community Survey (MCBS) respondents.

DESIGN

Cross-sectional analysis of a community survey.

SETTING

Community.

PARTICIPANTS

Twelve thousand seven hundred sixty-nine respondents from the 2001 MCBS, aged 65 and older.

MEASUREMENTS

Four questions from the MCBS were used to create four levels of mobility limitation: none, mild, moderate, and severe. Sampling weights were used to calculate estimates of means and proportions of the entire Medicare population for each mobility limitation category. A polytomous logistic regression analysis was used to model the association between four levels of mobility limitation and sociodemographic and clinical variables.

RESULTS

Prevalence of mobility limitations ranged from 9.5 million (mild) to 1.2 million (severe). Increasing severity of mobility limitation was associated with older age, being female, reporting fair or poor health, being overweight, smoking, having a greater number of comorbidities, having an annual income below $25,000, having less than a high school education, being unmarried, and living with others.

CONCLUSION

National prevalence estimates suggest that functional mobility limitation is a significant problem for many older adults and is associated with some potentially modifiable characteristics.

Design and validation of a methodology using the International Classification of Diseases, 9th Revision, to identify secondary conditions in people with disabilities

OBJECTIVE

To design and validate a methodology that identifies secondary conditions using International Classification of Disease, 9th Revision (ICD-9) codes.

DESIGN

Secondary conditions were identified through a literature search and a survey of Washington State physiatrists. These conditions were translated into ICD-9 codes and this list was then validated against a national sample of Medicare survey respondents with differing levels of mobility and activities of daily living (ADL) disability.

SETTING

National survey.

PARTICIPANTS

Participants (N=9731) in the 1999 Medicare Current Beneficiary Survey with no, mild, moderate, and severe mobility and ADL disability.

INTERVENTIONS

Not applicable.

MAIN OUTCOME MEASURE

Percentage of survey respondents with a secondary condition. The secondary conditions were grouped into 4 categories: medical, psychosocial, musculoskeletal, and dysphagia related (problems associated with difficulty in swallowing).

RESULTS

Our literature search and survey of 26 physiatrists identified 64 secondary conditions, including depression, decubitus ulcers, and deconditioning. Overall, 70.4% of all survey respondents were treated for a secondary condition. We found a significant relation between increasing mobility as well as ADL disability and increasing numbers of secondary conditions (chi 2 test for trend, P <.001). This relation existed for all categories of secondary conditions: medical (chi 2 test for trend, P <.001), psychosocial (chi 2 test for trend, P <.001), musculoskeletal (chi 2 test for trend, P <.001), and dysphagia related (chi 2 test for trend, P <.001).

CONCLUSIONS

We created a valid ICD-9-based methodology that identified secondary conditions in Medicare survey respondents and discriminated between people with different degrees of disability. This methodology will be useful for health services researchers who study the frequency and impact of secondary conditions.

Taking Part in Life: Enhancing Participation in Multiple Sclerosis

Health care professionals participating in rehabilitation for people with MS can play a critical role in enhancing limited outcomes such as enhanced mobility, reductions in symptoms such as pain and depression, and the metaoutcome-participation. This role will be significantly more effective if the health care professional acknowledges and validates the different perspectives of the professional and the patient and recognizes the expertise of the patient who has lived with MS in the context of his or her life. Assuming this role effectively requires that the health care professional develop a collaborative relationship with the patient and understand that the role may change depending on the stage of MS and the individual's circumstances.

The cost and benefits of employment: a qualitative study of experiences of persons with multiple sclerosis

OBJECTIVE

To attain a better understanding of the benefits and barriers faced by persons with multiple sclerosis (MS) in the workplace.

DESIGN

Qualitative research methodology comprising a series of semistructured interviews.

SETTING

Community-based setting.

PARTICIPANTS

Fourteen women and 2 men with MS living in the community who were employed or recently employed at the time of interviews.

INTERVENTIONS

Not applicable.

MAIN OUTCOME MEASURE

Accounts of personal experiences related to employment.

RESULTS

Four themes emerged: the cost-benefit economy of working; fatigue and cognitive changes; stress in the workplace; and accommodations made to address barriers. Although participants valued work highly, they were also aware of the cost of being employed. The consequences of unemployment or changing jobs were considered negative and appeared stressful. For persons with MS, employment had both costs and significant benefits. Accommodations in the workplace and modifications of roles and responsibilities at home made it possible for individuals to continue working.

CONCLUSIONS

Health care providers must consider the complexity and timing of decisions by people with MS to continue or leave employment before recommending either action. Identifying critical periods of intervention to stabilize this cost-benefit balance is a critical next step for understanding issues of employment and MS.

Getting the work done: a qualitative study of individuals with multiple sclerosis

THE PROBLEM

Work can be defined as an activity performed to accomplish something in the presence of obstacles that may make accomplishing the goal difficult. For individuals with MS, work is not only limited by physical impairments but also by factors such as fatigue and cognitive changes

PURPOSE

The aim of this study is to examine the experiences of individuals with mild to moderate MS as they carry out everyday work activities both inside and outside the home.

METHOD

Eleven women and three men were recruited from the community to participate in a series of semi-structured interviews. Using qualitative research methodology that examined the experiences of the participants, two major themes and seven subthemes emerged.

RESULTS

The first theme, Defining the work, included Priorities: seeing what's important; Plans: learning about resources and requirements; and

PERSPECTIVES

fixing it yourself. The second theme, Changing how things get done, includes Precipitating factors; Awareness; Constructing the strategies; and Evaluating the strategies.

CONCLUSIONS

Individuals with MS develop strategies and utilize resources in order to get the work done. Comparisons are made between existing intervention theories or programmes and the experiences described by participants in this study.

Accuracy of metamemory after traumatic brain injury: predictions during verbal learning

The primary intent of this study was to investigate the metamemory monitoring abilities of adult survivors of at least moderate traumatic brain injury (TBI) during a verbal-learning activity. Eighteen survivors and 18 non-injured control participants made judgment-of-learning (JOL) predictions of their recall ability immediately after studying 3 lists of noun-pairs or after a slight delay. A secondary intent of this study was to determine if verbal retrieval attempts would enhance predictive accuracy. One half of participants made retrieval attempts during the second and third list-learning task, and the other half made retrieval attempts during the third list-learning task only. Measures of the correlation between JOL predictions and recall accuracy revealed that survivors were as accurate as controls when making delayed predictions and were less accurate when making immediate predictions. This occurred regardless of retrieval attempts. Absolute measures that compared mean JOL ratings to overall recall revealed that the survivor group was well-calibrated when making delayed JOL predictions but overestimated when making immediate JOL predictions. The non-injured control group underestimated when making both types of predictions. However, within-group variability was high. These findings are compared to those from studies that investigated metamemory beliefs in which survivors' ratings were compared to family-member ratings. Clinical implications for basing executive decisions about compensatory strategies on delayed and immediate predictions of future recall are discussed. Additionally, a rationale is provided for the use of both relative and absolute measures of predictive accuracy in metamemory studies involving neurological clinical populations.

Functional outcome assessment in dysarthria

Strategies for the functional assessment of communication disorders experienced by persons with dysarthria can be based on the Chronic Disabilities Model described by Nagi (1991), which considers a disorders at five different levels, ranging from pathophysiology at the level of the tissue to the societal levels of dysfunction. Outcomes can be measured at all levels of the model. For example, at the pathophysiologic level, outcomes may indicate events at the tissue level during the course of the disease, whereas, at the level of the disability, outcomes reveal the adequacy of speech production using compensatory strategies in communicative contexts, and at the societal level, they may indicate the overall degree of success a speaker has in specific real-world speaking situations. This article focuses on "functional" assessment of persons with dysarthria. Thus, assessment is viewed from the perspective of how speech and the use of speech can be measured in functional situations over time or as a result of treatment.

Written language production and neuropsychological function in children with traumatic brain injury

OBJECTIVE

To establish the early consequences of traumatic brain injury (TBI) on spontaneous written language production in children by examining writing deficits as a function of injury severity and correlating written performance with neuropsychological data.

DESIGN

Case-control cohort study.

SETTING

Two regional medical centers.

PATIENTS

Seventy-six children, aged 8 to 15 years, with mild, moderate, or severe closed head injury were compared with controls who were individually matched on the premorbid characteristics of age, gender, school grade, behavior, and academic performance.

MAIN OUTCOME MEASURES

Assessment of written language production and neuropsychological function was undertaken approximately 1 month following resolution of posttraumatic amnesia. Case-control differences on 16 measures of spontaneous written narratives were computed.

RESULTS

Factor analysis and conceptual similarities suggested that the measures of written language fell into five domains: Efficiency, Completeness, General Readability, Error, and Vocabulary. A highly significant, moderate correlation between these measures and severity of injury was found. The highest correlations were found for the written language domains of Efficiency and Completeness and the lowest for the Vocabulary domain. Moderate correlations were also found between measures of written language and neuropsychological function.

CONCLUSIONS

At 1 month after resolution of posttraumatic amnesia, written language production in children with TBI is negatively correlated with severity of injury. Some aspects of written language production are affected to a greater extent than others. Considerable common ground was found between written language production and neuropsychological function.

Speech and pause characteristics following speech rate reduction in hypokinetic dysarthria

The effect of speech rate reduction on speech and pause characteristics during a reading task was examined for speakers with Parkinson's disease (PD) and a group of control speakers. Duration of utterances and characteristics of pausing (duration, interpause phrase length, and location) were determined. At habitual reading rate, subjects with PD had shorter speech duration and greater time per pause than control subjects. At reduced reading rates, subjects with PD increased speech duration so that it was equivalent to the control speakers at habitual rate. Both groups had the majority of their pause occurring at appropriate syntactic boundaries. Subjects with PD had a greater proportion of pauses occurring at syntactically inappropriate locations than did the controls. When speech rates were reduced, both groups showed a decrease in pauses located at appropriate syntactic boundaries. The implication of these findings on speech intelligibility is discussed.
