ABSTRACTThe Revised Preschool Language Assessment (RPLA) is a standardized measure for examining the language status of and determining potential language difficulties among preschoolers between 3 and 6 years old. To facilitate the applicability of the RPLA for use with Mandarin-speaking children, the present study adopted exploratory factor analysis (EFA) and Rasch analysis to assess the appropriateness of using a single total score to interpret children’s language ability. Mandarin-speaking children (N = 138) with no reported disabilities were recruited. Analyses suggested that the RPLA is a useful instrument for identifying differences in children based on language proficiency; however, analyses of total scores showed that the RPLA was not unidimensional; thus, reporting a single total score is not justified. Subsequently, EFA and Rasch analyses were performed in scales, yielding data reflecting separate unidimensional domains of language comprehension and oral expression. The person–item maps indicated that complexity in comprehension and expression increases and provides support for the validity of scores generated by using the measure. Thus, using separate ability indexes for language comprehension and oral expression rather than using one total score was suggested. Finally, applications involving screening and weighting items based on their difficulty levels in multidimensional language assessments were discussed.

To compare the initial referral rate, the accurate identification rate of congenital hearing loss, and the cost between one step with transient evoked otoacoustic emissions (TEOAEs), two steps with TEOAE and automated auditory brainstem response (AABR), and one step with AABR in newborn hearing screening program. The aim of this study is to compare their efficacy between our three different protocols and to see which one is most cost-effective. From November 1998 to April 2006, 25,588 healthy newborns were screened for hearing loss in Mackay Memorial Hospital, Taipei. In the periods from November 1998 to January 2004, from February 2004 to February 2005, and from March 2005 to April 2006, the screening tools used were TEOAE alone (n = 18,260), TEOAE plus AABR (n = 3,540), and AABR (n = 3,788), respectively. A statistically significant decrease in referral rate was achieved in the group using AABR as screening tools when compared with TEOAE plus AABR and TEOAE alone (0.8 versus 1.6 versus 5.8%). The accurate identification rate of congenital hearing loss was 0.42% in AABR protocol, 0.25% in TEOAE and AABR protocol, and 0.45% in TEOAE protocol, which was not statistically significant. The total direct costs (including predischarge screening and postdischarge follow-up costs) per screening were US $10.04 for the program using TEOAE alone, US $8.60 for TEOAE plus AABR, and US $7.33 for AABR. The intangible cost (parental anxiety) was much higher in the earlier program due to higher referral rate. In the efficacy of the hearing screening program using the one-step TEOAE, two-step TEOAE and AABR, and one-step AABR programs, the latter significantly decreased the referral rate from 5.8, to 1.6, and to 0.8%. No significant difference was noted between their accurate identification rates of congenital hearing loss. The total costs, including expenditures and intangible cost, were much lower in the protocol with AABR due to reduction in false positives.
