Purpose: This study compared the test characteristics, test–retest reliability, and test efficiency of three novel digits-in-noise (DIN) test procedures to a conventional antiphasic 23-trial adaptive DIN (D23). Method: One hundred twenty participants with an average age of 42 years ( SD  = 19) were included. Participants were tested and retested with four different DIN procedures. Three new DIN procedures were compared to the reference D23 version: (a) a self-selected DIN (DSS) to allow participants to indicate a subjective speech recognition threshold (SRT), (b) a combination of self-selected and adaptive eight-trial DIN (DC8) that utilized a self-selected signal-to-noise ratio (SNR) followed by an eight-trial adaptive DIN procedure, and (c) a fixed SNR DIN (DF) approach using a fixed SNR value for all presentations to produce a pass/fail test result. Results: Test–retest reliability of the D23 procedure was better than that of the DSS and DC8 procedures. SRTs from DSS and DC8 were significantly higher than SRTs from D23. DSS was not accurate to discriminate between normal-hearing and hard of hearing listeners. The DF and DC8 procedures with an adapted cutoff showed good hearing screening test characteristics. All three novel DIN procedure durations were significantly shorter (< 70 s) than that of D23. DF showed a reduction of 46% in the number of presentations compared to D23 (from 23 presentations to an average of 12.5). Conclusions: The DF and DC8 procedures had significantly lower test durations than the reference D23 and show potential to be more time-efficient screening tools to determine normal hearing or potential hearing loss. Further studies are needed to optimize the DC8 procedure. The reference D23 remains the most reliable and accurate DIN hearing screening test, but studies in which the potentially efficient new DIN procedures are compared to pure-tone thresholds are needed to validate these procedures.

In 1977, Shepherd and colleagues reported significant correlations (–.90, –.91) between speechreading scores and the latency of a selected negative peak (VN 130 measure) on the averaged visual electroencephalic wave form. The primary purpose of this current study was to examine the stability, or repeatability, of this relation between these cognitive and neurophysiologic measures over a period of several months and thus support its test-retest reliability. Repeated speechreading word and sentence scores were gathered during three test-retest sessions from each of 20 normal-hearing adults. An average of 56 days occurred from the end of one to the beginning of another speechreading sessions. During each of four other test-retest sessions, averaged visual electroencephalic responses (AVER s ) were evoked from each subject. An average of 49 clays intervened between AVER sessions. Product-moment correlations computed among repeated word scores and VN l30 measures ranged from –.61 to –.89. Based on these findings, it was concluded that the VN l30 measure of visual neural firing time is a reliable correlate of speech-reading in normal-hearing adults.

The paper measures a gamification effect in longitudinal web surveys among children and adolescents 7–15 years old. Two waves of the study were conducted using a volunteer online access panel in Russia among 737 children. Respondents were randomly assigned to one of the three conditions in the first wave without changing the treatment in the second wave: (1) a text-only survey, (2) a visual survey and (3) a gamified survey. Though in the first wave of the study respondents found it more enjoyable and easier to complete the gamified survey, no differences in participation rates were found between the conditions in the second wave. Contrary to expectations, a higher breakoff was found in the gamified condition. Moreover, it produced lower test-retest reliability correlations than the text-only and visual conditions in all survey questions. The promising gamification effect found in the first wave of the study faded in the second wave. It seems that implementing gamified elements in longitudinal web surveys might differ from the implementation of gamified elements in cross-sectional surveys.

The study investigated the test-retest reliability of the Slosson Intelligence Test when administered and scored by 9 special education teachers who had no experience in psychological testing. Subjects were 53 profoundly and severely retarded children, ranging in age from 5 to 16 yr. Pearson product-moment coefficients were .92 for girls, .96 for boys, and .94 for all subjects for scores on two occasions. The results support Slosson's contention that the test can be reliably administered by personnel with little psychometric knowledge.

Purpose The objective of the current study was to investigate the short-term test–retest reliability of contralateral suppression (CS) of click-evoked otoacoustic emissions (CEOAEs) using commercially available otoacoustic emission equipment. Method Twenty-three young normal-hearing subjects were tested. An otoscopic evaluation, admittance measures, pure-tone audiometry, measurements of CEOAEs without and with contralateral acoustic stimulation (CAS) to determine CS were performed at baseline ( n = 23), an immediate retest without and with refitting of the probe (only CS of CEOAEs; n = 11), and a retest after 1 week ( n = 23) were performed. Test–retest reliability parameters were determined on CEOAE response amplitudes without and with CAS, and on raw and normalized CS indices between baseline and the other test moments. Results Repeated-measures analysis of variance indicated no random or systematic changes in CEOAE response amplitudes without and with CAS, and in raw and normalized CS indices between the test moments. Moderate-to-high intraclass correlation coefficients with mostly high significant between-subjects variability between baseline and each consecutive test moment were found for CEOAE response amplitude without and with CAS, and for the raw and normalized CS indices. Other reliability parameters deteriorated between CEOAE response amplitudes with CAS as compared to without CAS, between baseline and retest with probe refitting, and after 1 week, as well as for frequency-specific raw and normalized CS indices as compared to global CS indices. Conclusions There was considerable variability in raw and normalized CS indices as measured using CEOAEs with CAS using commercially available otoacoustic emission equipment. More research is needed to optimize the measurement of CS of CEOAEs and to reduce influencing factors, as well as to make generalization of test–retest reliability data possible.

Numerous techniques have been used in attempts to find a reliable and efficient screening method for determining auditory function in the newborn. The brainstem auditory evoked potential (BAEP) is the latest method advocated for that purpose. The BAEP was evaluated as a hearing screening test in 168 high-risk newborns between 35 and 45 weeks of conceptual age. Follow-up data were obtained after 1 year (mean 17.3 months) on 134 of the infants (80%). Normal hearing was defined as a reproducible response in both ears to a 25 dB normal hearing level (nHL) click stimulus; 21 infants (12.5%) failed the initial screening test. Follow-up on 19/21 infants revealed 18 infants with normal hearing and one infant with an 80 dB nHL bilateral hearing loss substantiated. One infant with an abnormal screening test died before retesting, and the other infant was lost to follow-up but had only a unilaterally abnormal BAEP. None of the infants with a normal BAEP screening study had evidence of hearing loss on retesting. Sensitivity of the BAEP was 100%, specificity was 86%, predictive value of a positive test was 5.26%, and the predictive value of a negative test was 100%. The incidence of significant hearing loss in our population was between 0.75% (1/134 infants) confirmed, and 2.24% (3/134 infants) including infants who failed screening but were lost to follow-up. The BAEP is a sensitive procedure for the early identification of hearing-impaired newborns. However, the yield of significant hearing abnormalities was less than predicted in other studies using BAEP for newborn hearing screening.

Psychometric evaluations were performed on a self-perceived localization disabilities and handicaps questionnaire. Twenty individuals with normal hearing bilaterally, twenty with profound unilateral hearing impairment (UHI), and ten with any degree of bilateral hearing impairment participated. Each subject completed the questionnaire. Comparisons of the responses of the subjects with normal hearing and those with UHI revealed significant differences among the groups for both disabilities and handicaps, establishing construct validity. Cronbach's Alpha correlational analyses of the responses of all subjects with hearing impairment revealed correlations of .900 (disabilities) and .800 (handicaps), establishing internal consistency. Each participant with hearing impairment was asked to complete the questionnaire again after three weeks. Pearson's correlational analyses of the responses at time one versus time two revealed correlations of .900 (disabilities) and .700 (handicaps), establishing test/retest reliability. This questionnaire is an appropriate tool for investigating the self-perceived localization disabilities and handicaps of individuals with hearing impairment.
