Sensitivity of the Communicative Participation Item Bank for Measuring Patient-Reported Outcomes After Treatment of Unilateral Vocal Fold Immobility

The Communicative Participation Item Bank-Gender-Diverse Version: Item Bank Calibration and Short Form

PURPOSE

The purpose of this study was to calibrate an item set for a new version of the Communicative Participation Item Bank (CPIB) specifically for use with gender-diverse clients. This new version contains a new item stem as well as other minor wording changes from the original CPIB in order to be acceptable to gender-diverse respondents.

METHOD

Survey data on 47 candidate items were collected from 434 transgender individuals: 219 assigned female at birth (AFAB) and 215 assigned male at birth (AMAB). Item response theory analyses included evaluation of unidimensionality, local dependence, fit to a graded response model, and differential item functioning (DIF) between AFAB and AMAB respondents.

RESULTS

The original set of 47 items was unidimensional, but 16 items were removed due to local dependence, resulting in a final item bank of 31 items. There was no evidence of DIF between AFAB and AMAB participants. Reliability of the full item bank is good (i.e., > 0.8) between T scores of 20 and 76 and high (i.e., > 0.9) between T scores of 20 and 68. The short form had good reliability (i.e., > 0.8) between T scores of 24 and 64.

CONCLUSIONS

The Communicative Participation Item Bank-Gender-Diverse (CPIB-GD) version provides a new option for person-reported outcome measurement with gender-diverse clients. Clinicians are cautioned to use only the new CPIB-GD with gender-diverse clients, and not the original CPIB due to unacceptable wording in the original version for this population. The original CPIB remains valid and appropriate for the populations for which it was developed.

Communicative participation outcomes in individuals with Parkinson's disease receiving standard care speech-language therapy services in community settings

BACKGROUND

The Communicative Participation Item Bank (CPIB) is a patient-reported outcome measure (PROM) designed to measure the extent of interference, or difficulty, experienced by adults with communication disorders participating in their day-to-day communication activities. To date, there is limited evidence regarding sensitivity of the CPIB for capturing change with intervention in people with Parkinson's disease (PwPD).

AIMS

The purpose of this study was to examine the following measurement properties of the CPIB in PwPD who received community-based, standard care, speech-language therapy focusing on motor speech concerns: Change over time between treatment and observation groups, comparison to patient-defined ideal and satisfactory targets, comparison of static short form to computerised adaptive testing (CAT), comparison of self to proxy-rated scores, and comparison to other common PROMs.

METHODS AND PROCEDURES

Forty-six PwPD (20 treatment/26 observation) completed data collection upon enrolment (pre-treatment) and 6 months later. In addition to the CPIB, PROMs included the Voice Handicap Index 10-item short form (VHI-10), PROMIS Global Health-Related Quality of Life, Levels of Speech Usage, self-rated speech severity, and Patient Health Questionnaire-9 (PHQ-9). Participants also engaged in qualitative interviews. Forty-four family members completed proxy CPIB ratings.

OUTCOMES AND RESULTS

There were no significant differences between treatment and observation groups on the CPIB pre-treatment, but there were significant differences post-treatment. The differences appeared to be largely due to significant gains in the treatment group. No participants reached their ideal CPIB target, and few reached their satisfactory target. Static CPIB short form and CAT scores were not significantly different, with an average of five CAT items administered per participant. Overall group similarities between patient and proxy scores may have obscured wide variability across individual patient-proxy pairs. Associations between CPIB and VHI-10, health-related quality of life, self-reported speech severity, and depression ranged from weak to moderate.

CONCLUSIONS AND IMPLICATIONS

The CPIB appears to be sensitive to capturing change with intervention, and similar results are obtained with the static short form and CAT formats. One clinical caution is that even with gains observed in the treatment group, no participants obtained their ideal communicative participation goals, and few obtained a satisfactory level of communicative participation. Thus, while current interventions are beneficial, they may not meet the full range of clients' communication needs. While responding to the CPIB through a proxy rater may be feasible, caution is warranted due to concerns about maintaining the autonomy of PwPD.

WHAT THIS PAPER ADDS

What is already known on this subject The communication disorders associated with Parkinson's disease (PD) can have a negative impact on quality of life and life participation as measured by patient (or person)-reported outcome measures (PROMs). The Communicative Participation Item Bank (CPIB) is one PROM available to use with adults with communication disorders. However, little is known about whether the CPIB captures changes in communicative participation as a result of standard care treatment for people with Parkinson's disease (PwPD). Use of computerised adaptive testing (CAT), proxy report and comparison to targeted participation outcomes have not been explored. What this study adds to existing knowledge As a result of this study, we know that the CPIB captured differences between treatment and observation groups after community-based, standard care speech therapy intervention focusing on motor speech production in PwPD. Static short form and CAT scores did not differ significantly, so the CAT option provides better efficiency requiring, on average, five items to administer compared to the 10-item short form. Proxy and PwPD scores did not differ as a group, but wide variability was noted. What are the potential or actual clinical implications of this work? The CPIB may be a clinically sensitive instrument for capturing changes in communicative participation after treatment. No participants met their ideal CPIB target, and few reached their satisfactory target, suggesting that while current interventions contribute to gains in communicative participation, there are still unmet needs that may call for support and interventions addressing the more complex array of factors affecting communicative participation outcomes for PwPD.

Exploring Patient's Preference of Patient-Reported Outcome Measures in Laryngeal Movement Disorders

BACKGROUND

Despite many available patient-reported outcome measures (PROMs) for laryngeal movement disorders, there is a lack of patient input regarding which PROM most accurately and conveniently captures aspects related to their vocal disease. This study aimed to assess patients' preferences among a selection of voice-related PROMs (Voice Handicap Index-10 [VHI-10], OMNI-Vocal Effort Scale [OMNI-VES], Communicative Participation Item Bank-General Short Form [CPIB-10], and Visual Analog Scales [VAS]) within the laryngeal movement disorder population and investigate associations between selected instruments.

METHODS

Prior to botulinum toxin A injection, patients with laryngeal dystonia and/or essential tremor of the vocal tract were administered the VHI-10, OMNI-VES, CPIB-10, and three novel VAS questions in a randomized order. Patients rank ordered the four PROMs based on the PROMs' reflection of their voice problems. Pearson's correlation coefficients evaluated pairwise associations among PROM scores. Fisher's exact test compared the preferred PROM rankings.

RESULTS

Seventy patients (53 female, mean age = 60.7 years) participated. The VHI-10 and CPIB-10 were most preferred at 33.9% and 27.4% respectively. The OMNI-VES and VAS scales were less favored (19.4%, each). When analyzed by age ≥60 years, the CPIB-10 was most favored (33.3%), but for age <60 years, VHI-10 was most preferred (42.3%). There was a strong correlation between scores of all administered PROMs (strongest correlation between OMNI-VES and VAS, r = 0.8, p < 0.001; the weakest correlation between OMNI-VES and VHI-10, r = 0.6, p < 0.001).

CONCLUSIONS

With an increasing trend in PROMs usage and a strong correlation between all evaluated outcome instruments, insight regarding patients' PROM preferences is an area for further consideration.

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.
