Music-based interventions for people with profound and multiple learning disabilities: A systematic review of the literature.

Music is motivational, accessible and engaging for individuals with learning disabilities. Several systematic reviews have addressed the effects of music activity on people with learning disabilities; however, none has specifically reviewed the use of musical activity with people with profound and multiple learning disabilities.This review aimed to: 1. identify peer-reviewed studies and describe the characteristics of evidence-based musical activity used with people with profound and multiple learning disabilities and 2. evaluate and analyse the effectiveness of these music-based interventions and identify gaps within current research. A systematic search was conducted in April 2021 identifying seven peer-reviewed studies which included music-based interventions with at least one person with profound and multiple learning disabilities.Findings reveal the interventions varied in their frequency, duration and content. The outcome of most (n=6) interventions documented the development of the participants' social skillset. Interventions were predominantly (n=6) implemented by facilitators with musical expertise. The diverse and novel nature of the reviewed studies highlights a need to expand and enhance research with this population.

Language and reading comprehension in middle childhood predicts emotional and behaviour difficulties in adolescence for those with permanent childhood hearing loss.

BACKGROUND: Permanent childhood hearing loss (PCHL) is associated with an elevated level of emotional and behaviour difficulties (EBD). In children and adolescents with PCHL, EBD has been found to be linked to language ability in children with PCHL. The present study was designed to test whether childhood language and/or reading comprehension abilities of children with PCHL predict subsequent EBD in adolescence. METHODS: Language comprehension (LC) and reading comprehension (RC) were measured at ages 6-10 years (Time 1) and 13-20 years (Time 2) in participants with PCHL who preferred to communicate using spoken language (n = 57) and a hearing comparison group (n = 38). EBD was measured at both time points by parent and by teacher ratings on the Strengths and Difficulties Questionnaire. RESULTS: Within the PCHL group there were negative correlations between EBD scores and concurrent LC and RC scores at Time 1 and at Time 2. Cross-lagged latent variable models fitted to the longitudinal data indicated that the associations between LC, RC and teacher-rated EBD were more likely to arise from the impact of LC and RC on behaviour rather than the other way around. CONCLUSIONS: In those with PCHL, poor language and reading comprehension in middle childhood increased the risk of emotional and behaviour difficulties at school in the teenage years. The results suggest that effective language and literacy interventions for children with hearing loss may also bring benefits to their mental health.

Emotional and behaviour difficulties in teenagers with permanent childhood hearing loss.

OBJECTIVES: It is known that during the middle childhood years those with permanent childhood hearing loss (PCHL) are at increased risk of showing emotional and behaviour difficulties (EBD). It has yet to be established whether this risk continues into the late teenage years. There is a paucity of longitudinal studies on the association between PCHL and EBD. METHODS: The Strengths and Difficulties Questionnaire (SDQ) was used to measure EBD based on parent, teacher and self-ratings in 76 teenagers with PCHL and 38 in a hearing comparison group (HCG) from a population sample of children that was followed up from birth to adolescence. RESULTS: On parent-rated SDQ, the PCHL group had significantly higher Total Difficulties score than the HCG (Standardised mean difference (SMD) = +0.39, 95%CI 0.00 to 0.79). Amongst the PCHL group the presence of disabilities other than hearing loss had a substantial impact on the level of parent-rated EBD (SMD = +1.68, 1.04 to 2.33). There was a relationship between receptive language ability and EBD in both the HCG (r = -0.33, 95%CI -0.59 to -0.01) and the PCHI group (r = -0.33, 95%CI -0.53 to -0.02). The effect of PCHL on EBD became non-significant when receptive language was included as a covariate (F = 0.12, df = 1,95, p = 0.729). Early confirmation of hearing loss (i.e. before 9 months of age) did not have a significant effect on EBD scores (SMD = +0.31, 95%CI -0.15 to 0.77). CONCLUSIONS: PCHL continues to be associated with elevated EBD scores as measured by parent rated SDQ into the late teenage years but the degree of this elevation is less than in childhood and is not apparent on teacher or self-ratings. Poor receptive language ability appeared to account for these elevated EBD scores in the group with PCHL. Particular attention needs to be paid to the mental health of children and adolescents with PCHL that is accompanied by other disabilities and to those with poor receptive language ability. However, the majority of teenagers with PCHL do not show clinically significant elevated levels of EBD.

Concurrent and Longitudinal Predictors of Reading for Deaf and Hearing Children in Primary School.

Forty-one children with severe-profound prelingual hearing loss were assessed on single word reading, reading comprehension, English vocabulary, phonological awareness and speechreading at three time points, 1 year apart (T1-T3). Their progress was compared with that of a group of hearing children of similar nonverbal IQ, initially reading at the same level. Single word reading improved at each assessment point for the deaf children but there was no growth in reading comprehension from T2 to T3. There were no differences between children with cochlear implants and those with hearing aids on either reading measure but orally educated children had higher scores than children who signed in the classroom. English vocabulary and speechreading were the most consistent longitudinal predictors of reading for the deaf children. Phonological awareness was the most consistent longitudinal predictor for the hearing group and also a concurrent predictor of reading at T3 for both groups. There were many more significant correlations among the various measures for the deaf children than the hearing at both T1 and T3, suggesting that skills underpinning reading, including phonological awareness and vocabulary, are more closely related for deaf children. Implications of these findings for of deaf children's literacy are explored.

Language Outcomes in Deaf or Hard of Hearing Teenagers Who Are Spoken Language Users: Effects of Universal Newborn Hearing Screening and Early Confirmation.

OBJECTIVES: This study aimed to examine whether (a) exposure to universal newborn hearing screening (UNHS) and b) early confirmation of hearing loss were associated with benefits to expressive and receptive language outcomes in the teenage years for a cohort of spoken language users. It also aimed to determine whether either of these two variables was associated with benefits to relative language gain from middle childhood to adolescence within this cohort. DESIGN: The participants were drawn from a prospective cohort study of a population sample of children with bilateral permanent childhood hearing loss, who varied in their exposure to UNHS and who had previously had their language skills assessed at 6-10 years. Sixty deaf or hard of hearing teenagers who were spoken language users and a comparison group of 38 teenagers with normal hearing completed standardized measures of their receptive and expressive language ability at 13-19 years. RESULTS: Teenagers exposed to UNHS did not show significantly better expressive (adjusted mean difference, 0.40; 95% confidence interval [CI], -0.26 to 1.05; d = 0.32) or receptive (adjusted mean difference, 0.68; 95% CI, -0.56 to 1.93; d = 0.28) language skills than those who were not. Those who had their hearing loss confirmed by 9 months of age did not show significantly better expressive (adjusted mean difference, 0.43; 95% CI, -0.20 to 1.05; d = 0.35) or receptive (adjusted mean difference, 0.95; 95% CI, -0.22 to 2.11; d = 0.42) language skills than those who had it confirmed later. In all cases, effect sizes were of small size and in favor of those exposed to UNHS or confirmed by 9 months. Subgroup analysis indicated larger beneficial effects of early confirmation for those deaf or hard of hearing teenagers without cochlear implants (N = 48; 80% of the sample), and these benefits were significant in the case of receptive language outcomes (adjusted mean difference, 1.55; 95% CI, 0.38 to 2.71; d = 0.78). Exposure to UNHS did not account for significant unique variance in any of the three language scores at 13-19 years beyond that accounted for by existing language scores at 6-10 years. Early confirmation accounted for significant unique variance in the expressive language information score at 13-19 years after adjusting for the corresponding score at 6-10 years (R change = 0.08, p = 0.03). CONCLUSIONS: This study found that while adolescent language scores were higher for deaf or hard of hearing teenagers exposed to UNHS and those who had their hearing loss confirmed by 9 months, these group differences were not significant within the whole sample. There was some evidence of a beneficial effect of early confirmation of hearing loss on relative expressive language gain from childhood to adolescence. Further examination of the effect of these variables on adolescent language outcomes in other cohorts would be valuable.

Literacy Outcomes for Primary School Children Who Are Deaf and Hard of Hearing: A Cohort Comparison Study.

Purpose: In this study, we compared the language and literacy of two cohorts of children with severe-profound hearing loss, recruited 10 years apart, to determine if outcomes had improved in line with the introduction of newborn hearing screening and access to improved hearing aid technology. Method: Forty-two children with deafness, aged 5-7 years with a mean unaided loss of 102 DB, were assessed on language, reading, and phonological skills. Their performance was compared with that of a similar group of 32 children with deafness assessed 10 years earlier and also a group of 40 children with normal hearing of similar single word reading ability. Results: English vocabulary was significantly higher in the new cohort although it was still below chronological age. Phonological awareness and reading ability had not significantly changed over time. In both cohorts, English vocabulary predicted reading, but phonological awareness was only a significant predictor for the new cohort. Conclusions: The current results show that vocabulary knowledge of children with severe-profound hearing loss has improved over time, but there has not been a commensurate improvement in phonological skills or reading. They suggest that children with severe-profound hearing loss will require continued support to develop robust phonological coding skills to underpin reading.

The impact of universal newborn hearing screening on long-term literacy outcomes: a prospective cohort study.

OBJECTIVE: To determine whether the benefits of universal newborn hearing screening (UNHS) seen at age 8 years persist through the second decade. DESIGN: Prospective cohort study of a population sample of children with permanent childhood hearing impairment (PCHI) followed up for 17 years since birth in periods with (or without) UNHS. SETTING: Birth cohort of 100 000 in southern England. PARTICIPANTS: 114 teenagers aged 13-19 years, 76 with PCHI and 38 with normal hearing. All had previously their reading assessed aged 6-10 years. INTERVENTIONS: Birth in periods with and without UNHS; confirmation of PCHI before and after age 9 months. MAIN OUTCOME MEASURE: Reading comprehension ability. Regression modelling took account of severity of hearing loss, non-verbal ability, maternal education and main language. RESULTS: Confirmation of PCHI by age 9 months was associated with significantly higher mean z-scores for reading comprehension (adjusted mean difference 1.17, 95% CI 0.36 to 1.97) although birth during periods with UNHS was not (adjusted mean difference 0.15, 95% CI -0.75 to 1.06). The gap between the reading comprehension z-scores of teenagers with early compared with late confirmed PCHI had widened at an adjusted mean rate of 0.06 per year (95% CI -0.02 to 0.13) during the 9.2-year mean interval since the previous assessment. CONCLUSIONS: The benefit to reading comprehension of confirmation of PCHI by age 9 months increases during the teenage years. This strengthens the case for UNHS programmes that lead to early confirmation of permanent hearing loss. TRIAL REGISTRATION NUMBER: ISRCTN03307358.

Reading and spelling abilities of deaf adolescents with cochlear implants and hearing AIDS.

A total of 86 deaf children aged between 12 and 16 years were recruited from schools for the deaf, specialist units attached to a school, and mainstream schools. Approximately one-third used hearing aids, one-third had received a cochlear implant before 42 months, and one-third had been implanted later. The 3 subgroups were matched for age and nonverbal IQ, and all had an unaided hearing loss of at least 85 dB. Assessments revealed mean reading ages that were several years below chronological age for all 3 groups. However, participants in the hearing aid group performed best. Reading levels were not predicted by age of diagnosis or degree of hearing loss, but there was a relationship between reading level and presence of phonetic errors in spelling. There were also differences in educational setting, with the great majority of children in the hearing aid group in a school for the deaf and relatively more of the children with cochlear implants being educated in a unit or mainstream setting.
