Consolidating the Academic End of a Community-Based Participatory Research Venture to Address Health Disparities.

Although there is strong support for community engagement and community-based participatory research (CBPR) from public health entities, medical organizations, and major grant-funding institutions, such endeavors often face challenges within academic institutions. Fostering the interest, skills, and partnerships to undertake participatory research projects and truly impact the community requires an interdisciplinary team with the competencies and values to engage in this type of research. Discussed in this article is how a CBPR-focused team evolved at a southern university, with emphasis on the activities that supported group identity, contributed to its evolution, and positioned the group to speak with authority in promoting CBPR as a tool for addressing health disparities.

Auditory and Visual Cues for Topic Maintenance with Persons Who Exhibit Dementia of Alzheimer's Type.

This study compared the effectiveness of auditory and visual redirections in facilitating topic coherence for persons with Dementia of Alzheimer's Type (DAT). Five persons with moderate stage DAT engaged in conversation with the first author. Three topics related to activities of daily living, recreational activities, food, and grooming, were broached. Each topic was presented three times to each participant: once as a baseline condition, once with auditory redirection to topic, and once with visual redirection to topic. Transcripts of the interactions were scored for overall coherence. Condition was a significant factor in that the DAT participants exhibited better topic maintenance under visual and auditory conditions as opposed to baseline. In general, the performance of the participants was not affected by the topic, except for significantly higher overall coherence ratings for the visually redirected interactions dealing with the topic of food.

The influence of dialect upon the perception of dysarthic speech.

The purpose of this study was to determine the influence of dialect upon the perception of dysarthric speech. Speakers and listeners were self-identifying as either Caucasian American or African American. Three speakers were Caucasian American, three were African American. Four speakers had experienced a CVA and were dysarthric. Listeners were age matched and were equally divided for gender. Readers recorded 14 word sentences from the Assessment of Intelligibility of Dysarthric Speech. Listeners provided ratings of intelligibility, comprehensibility, and acceptability. Own-race biases were found for all measures; however, significant findings were found for intelligibility and comprehensibility in that the Caucasian Americans provided significantly higher scores for Caucasian American speakers. Clinical implications are discussed.

Comparison of language skills of adjudicated and nonadjudicated adolescent males and females.

PURPOSE: This study attempted to determine whether there were any differences or similarities in the basic cognitive and language skills of 4 groups of adolescents: adjudicated (a judge's decision to establish responsibility for a delinquent act) and nonadjudicated male and females. METHOD: The 4 groups of adolescents were 18 adjudicated females, 18 nonadjudicated females, 14 adjudicated males, and 14 nonadjudicated males. They were evaluated using the Kaufman Brief Intelligence Test (K-BIT; A. S. Kaufman & N. L. Kaufman, 1990) as a screener for intelligence and the Clinical Evaluation of Language Fundamentals-3 (CELF-3; E. Semel, E. Wiig, & W. Secord, 1995) as a screener for language skills. RESULTS: No gender differences were found between the groups for either the K-BIT or the CELF-3. All groups scored within normal limits on the K-BIT subtests, but lower on the vocabulary portion of the K-BIT compared to the matrices (nonverbal) portion. There were differences found between adjudicated and nonadjudicated groups on the CELF-3, with the adjudicated groups having lower scores. IMPLICATIONS: As the majority of adjudicated adolescents had not been previously identified as having difficulties with language abilities, this population could benefit from early assessment. Also, children who are at risk for incarceration should be screened for possible language deficits that could contribute to the many difficulties experienced by adolescents.

Effects of reverberation and filtering on speech rate judgment.

This study investigated the effects of listening condition on speech rate judgment. Four listening conditions, in which a single sentence was presented at 21 speech rates ranging from 90 WPM to 250 WPM, were incorporated. These conditions included non-degraded, reverberation, band-pass filtered, and low-pass filtered conditions, each of which was selected to simulate listening conditions one might encounter in daily life. The participants were 20 young adults (20 to 40 years) with normal hearing. They were asked to make judgments of the rates of speech randomly presented in the four listening conditions using an equal-interval 5-step scale from too slow through too fast. Overall, speech rate was judged to be faster in the reverberant condition than in the other three conditions. These findings may have implications for auditory rehabilitation and counseling.

Speech rate effects upon intelligibility and acceptability of dysarthric speech.

Sentences recorded by four speakers with dysarthria and two control speakers were presented to listeners at three different rates: habitual, a 30% slower rate and a 30% higher rate. Rate changes were made by digitally manipulating the habitual sentences. Thirty young normal adult listeners rated the sentences for intelligibility (per cent correct words) and acceptability (via 9-point equal interval scale ranging from "terrible" through "excellent"). Intelligibility for each speaker remained unchanged across rate changes. Acceptability improved as rates increased for the two more intelligible impaired speakers. For the less intelligible impaired speakers, ratings were better and similar for the habitual and fast speaking rate conditions. Results are discussed in terms of the objective nature of intelligibility ratings vs. the subjective ratings of acceptability.
