Purpose
The Spatial Hearing Questionnaire (SHQ) was developed to address how to measure spatial-hearing ability in complex listening situations (Tyler, Perreau, & Ji, 2009). It has been translated and validated into various languages, including Chinese, Dutch, French, and Persian. Although the SHQ contains only 24 items, it could be time-consuming in a busy clinic to administer. The purposes of this study were to develop and validate a shortened version of the SHQ (SHQ-S) and to compare self-perceived spatial-hearing ability across adults with normal hearing (NH), hearing loss (HL), and cochlear implants (CIs).
Method
This was a retrospective study. The full version of the SHQ was administered to measure self-perceived spatial-hearing ability for 51 adults with NH at Augustana College, 47 adults with essentially mild to moderately severe sensorineural HL at Illinois State University, and 72 adult CI users at the University of Iowa. Exploratory factor analysis was performed for the full version for the data collected from adults with NH and HL. Appropriate items were chosen to develop the SHQ-S from the results of the exploratory factor analysis. Confirmatory factor analysis was then applied to test the factor structure of the SHQ-S for all participants. One-way analysis of variance was used to compare the self-perceived spatial-hearing performance scores between the 3 groups.
Results
The exploratory factor analysis revealed scores loaded on 2 factors. Six items from the full version were chosen accordingly. The results of the confirmatory factor analysis indicated that that a shortened version of 6 items is sufficient to measure spatial-hearing ability. The internal consistency reliability of the SHQ-S was high. The main effect of the one-way analysis of variance was significant for the groups, F(2, 167) = 36.0, p p values Conclusionsfrom #Audiology via xlomafota13 on Inoreader http://ift.tt/2tU9ikc
