Purpose: Hyperacusis is an uncommon hearing disorder, known as increased sensitivity to daily surrounding sounds. This disorder can profoundly affect people's daily activities. The studies conducted about hyperacusis are very limited in Iran. The purposes of this study are the psychometric evaluation of the Persian version of the Hyperacusis Questionnaire (PHQ) and the investigation of its prevalence. Method: This cross-sectional study was accomplished on 203 young university students with normal hearing sensitivity. After translating the questionnaire, the psychometric properties of the PHQ were evaluated by content validity ratio (CVR) and index (CVI) and exploratory factor analysis (EFA). Students were evaluated by clinical audiology tests, the loudness discomfort level (LDL) measurement, and answering the PHQ. The research data collection was done from April to November 2022. Otoscopy, clinical and speech audiometry, and LDL were all executed, respectively. The participants directly answered the PHQ. All statistical analyses were performed using SPSS software Version 26. Results: The PHQ demonstrated acceptable validity and reliability, Cronbach's alpha (.81), CVI (> 0.88), and CVR (> 0.98). EFA revealed four dimensions of the questionnaire. Of the participants, four (2%) were identified as suffering from hyperacusis. The PHQ showed the possibility of differences between genders. Conclusions: The psychometric evaluations of the PHQ were found to be acceptable and can be used in future studies. The prevalence of hyperacusis in our sample was 2%, and estimated to be higher in females. These findings suggest the need for further research on hyperacusis in Iranian population and specified studies to compare the two genders. [ABSTRACT FROM AUTHOR]

Purpose: The purpose of this study was to evaluate the internal consistency and construct validity of the Traumatic Brain Injury Quality of Life Communication Item Bank (TBIQOL COM) short form as a parent-proxy report measure. The TBI-QOL COM is a patient-reported outcome measure of functional communication originally developed as a selfreport measure for adults with traumatic brain injury (TBI), but it may also be valid as a parent-proxy report measure for children who have sustained TBI. Method: One hundred twenty-nine parent-proxy raters completed the TBI-QOL COM short form 6 months postinjury as a secondary aim of a multisite study of pediatric TBI outcomes. The respondents' children with TBI were between 8 and 18 years old (Mage = 13.2 years old) at the time of injury, and the proportion of TBI severity mirrored national trends (73% complicated-mild; 27% moderate or severe). Results: The parent-proxy report version of the TBI-QOL COM displayed strong internal consistency (ordinal α = .93). It also displayed evidence of known-groups validity by virtue of more severe injuries associated with more abnormal scores. The instrument also showed evidence of convergent and discriminant validity by displaying a pattern of correlations with other constructs according to their conceptual relatedness to functional communication. Conclusions: This preliminary psychometric investigation of the TBI-QOL COM supports the further development of a parent report version of the instrument. Future development of the TBI-QOL COM with this population may include expanding the content of the item bank and developing calibrations specifically for parent-proxy raters. [ABSTRACT FROM AUTHOR]

Purpose: This research provided a first-generation standardization of automated language environment estimates, validated these estimates against standard language assessments, and extended on previous research reporting language behavior differences across socioeconomic groups. Method: Typically developing children between 2 to 48 months of age completed monthly, daylong recordings in their natural language environments over a span of approximately 6–38 months. The resulting data set contained 3,213 12-hr recordings automatically analyzed by using the Language Environment Analysis (LENA) System to generate estimates of (a) the number of adult words in the child’s environment, (b) the amount of caregiver–child interaction, and (c) the frequency of child vocal output. Results: Child vocalization frequency and turn-taking increased with age, whereas adult word counts were age independent after early infancy. Child vocalization and conversational turn estimates predicted 7%– 16% of the variance observed in child language assessment scores. Lower socioeconomic status (SES) children produced fewer vocalizations, engaged in fewer adult–child interactions, and were exposed to fewer daily adult words compared with their higher socioeconomic status peers, but within-group variability was high. Conclusions: The results offer new insight into the landscape of the early language environment, with clinical implications for identification of children at-risk for impoverished language environments.

Purpose: Our purpose was to explore the validity and reliability of the German Focus on the Outcomes of Communication Under Six (FOCUS-G; Thomas-Stonell, Oddson, Robertson, & Rosenbaum, 2010, 2012), which is an authorized adaptation of the Focus on the Outcomes of Communication Under Six (Thomas-Stonell et al., 2010) tool, which measures communicative participation in preschool children. Method: Parents of typically developing children (TDC) and of children with speech impairment (CSI) completed the FOCUS-G and the Questionnaire for Measuring Health-Related Quality of Life in Children (KiddyKINDL; Ravens-Sieberer & Bullinger, 2000). To determine test-retest reliability, the FOCUS-G was readministered to a subsample of parents 1 week later. Results: The FOCUS-G had high values for internal consistency (α = .959, Ω = .941), test-retest reliability (intraclass correlation coefficient = .974), and split-half reliability (r = .832). Total scores on the FOCUS-G and KiddyKINDL demonstrated significant associations. FOCUS-G total scores and subdomain scores for both samples showed significant correlations, indicating good construct validity. The discriminatory ability of the FOCUS-G was indicated by significantly higher mean scores for TDC (M = 6.03, SD = 0.65) than CSI (M = 5.47, SD = 1.02). Conclusion: The overall good psychometric properties of this novel assessment of communicative participation support its use by speech-language pathologists for clinical and research purposes with German-speaking children.
