Randomised controlled trial of improvisational music therapy's effectiveness for children with autism spectrum disorders (TIME-A): study protocol

Collaborative arts therapies as a supportive intervention for autism spectrum disorders: Bibliometric analysis, insights, and directions

Purpose

Arts therapies (ATs) for the treatment of autism spectrum disorders (ASD) has attracted widespread attention from scholars. However, resources, technical, and ethical issues still pose significant obstacles to current research. A collaborative design approach is needed to guide the intervention treatment process involving multiple stakeholders. Therefore, this study focuses on exploring the current status, development and potential value of the collaborative arts therapies (CATs), providing a comprehensive perspective for subsequent research.

Methods

The Web of Science, PubMed, ScienceDirect, and Cochrane Library were searched for publications up to August 30, 2023, related to the use of CATs for the treatment of ASD. CiteSpace was used to build a knowledge graph to achieve visual analysis of current research countries, institutions, journals, authors, and hot topics.

Results

A total of 845 articles met the inclusion criteria. In terms of quantity, the USA is the leading country which has the greatest influence in advancing the field. The University of Haifa is the most productive institution. Arteterapia Papeles De Arteterapia Y Educacion Artistica and Frontiers in Psychology occupy key publishing positions. The most central keywords were related to the quality of life of people with ASD. "family", "social robot" and "participation" are emerging topics in the research field. The positive impact of the combination of caregivers, technology and artistic media on enhancing connections between people with ASD and their everyday environment is the focus of current research.

Conclusions

Research on CATs as an adjunctive therapy for the treatment of ASD is evolving. Providing comprehensive rehabilitation and support intervention for patients with ASD is a key research direction. The research process requires more interdisciplinary resources and technical assistance. Collaboration will be the best way to improve the effectiveness of ATs.

Economic Evaluations of Music Therapy and Other Music-Based Interventions: A Scoping Review

The cost-effectiveness of an intervention is an important factor in health care decisions about which health care services should be publicly funded and/or approved as an eligible intervention for private insurance coverage. Music therapy as a health profession lacks substantial research on the cost-effectiveness of its services and there is no overview of existing data. We therefore conducted a scoping review. To contextualize and focus the scope, we describe different types of economic evaluations (EEs) and characterize four types of music interventions. Following the PRISMA extension for scoping reviews, we systematically searched six databases (EBSCOHost, ProQuest, Web of Science, APA PsycNet, Scopus, and Prospero) in January 2023, and, after screening the initial 1,041 hits, 26 references were included in the review. The results consist of 19 completed and 7 planned EEs published between 1999 and 2022, mainly in the United States. The results show a heterogeneous picture with regard to: (a) the health economic methods used, ranging from cost analyses to cost-effectiveness analyses (CEAs), and one social return on investment analysis; (b) the service users involved, ranging from neonatal intensive care patients to persons with dementia and care staff; (c) the outcomes and cost components examined in the respective studies; and (d) the type of study and the conclusions drawn from the results. Accordingly, this scoping review provides an up-to-date overview of health economic studies and identifies research gaps in the field of music interventions for health-related goals and aims to contribute to the discussion on this topic.

Time to breastfeeding cessation and its predictors among mothers of index children aged 2-3 years in Bedele Town, Southwest Ethiopia: a community-based retrospective follow-up study

Background

Breastfeeding ensures the survival and health of a child. The WHO recommends exclusive breastfeeding for the first 6 months and continuing for up to 2 years. However, the duration of breastfeeding is below what is recommended globally. In Ethiopia, more than a quarter of mothers stop breastfeeding before the second birth date. Information on time to breastfeeding cessation and its predictors is needed to address this issue.

Objective

To assess the time to the cessation of breastfeeding and its predictors among mothers who have children aged two to 2-3 years in southwest Ethiopia, 2022.Methods: A community-based retrospective follow-up study was conducted among 471 randomly selected mothers with children aged 2-3 years in Southwest Ethiopia from 1 April 2019 to 31 March 2022. An interviewer-administered pre-questionnaire was used to collect the data. The collected data were entered into Epidata version 4.6 and exported to STATA version 14.1 for analysis. Both bivariate and multivariable survival models were fitted. The Weibull proportional hazard model was used to identify predictors for time to breastfeeding cessation.

Result

The overall incidence of early cessation of breastfeeding was found to be 11.05 per 1000 person-months of the follow-up period. Nearly a quarter (23.38%) of mothers ceased breastfeeding early. Educational status (diploma and above) (AHR=2.49: 95% CI (1.27, 4.90)), not bottle feeding (AHR=0.32, 95% CI(0.13, 0.76)), complementary feeding before 6 months (AHR=1.82, 95% CI(1.40, 2.37), ≥4 ANC follow-up (AHR=0.60; 95% CI (0.37, 0.96)), number of children (2-4) (AHR=2.82, CI (1.73, 4.61)) and (>4) (AHR=3.66, CI (1.36, 9.87)) were independent predictors of early cessation of breastfeeding.

Conclusion

The time to breastfeeding cessation was higher than that reported in previous studies. Therefore, strengthening maternal health education and breastfeeding counselling at both the health facility and community levels is recommended.

Preventing fear return in humans: Music-based intervention during reactivation-extinction paradigm

In several research studies, the reactivation extinction paradigm did not effectively prevent the return of fear if administered without any intervention technique. Therefore, in this study, the authors hypothesized that playing music (high valence, low arousal) during the reconsolidation window may be a viable intervention technique for eliminating fear-related responses. A three-day auditory differential fear conditioning paradigm was used to establish fear conditioning. Participants were randomly assigned into three groups, i.e., one control group, standard extinction (SE), and two experimental groups, reactivation extinction Group (RE) and music reactivation extinction (MRE), of twenty participants in each group. Day 1 included the habituation and fear acquisition phases; on Day 2 (after 24 hours), the intervention was conducted, and re-extinction took place on Day 3. Skin conductance responses were used as the primary outcome measure. Results indicated that the MRE group was more effective in reducing fear response than the RE and SE groups in the re-extinction phase. Furthermore, there was no significant difference observed between SE and RE groups. This is the first study known to demonstrate the effectiveness of music intervention in preventing the return of fear in a healthy individual. Therefore, it might also be employed as an intervention strategy (non-pharmacological approach) for military veterans, in emotion regulation, those diagnosed with post-traumatic stress disorder, and those suffering from specific phobias.

Music therapy for autistic people

BACKGROUND

Social interaction and social communication are among the central areas of difficulty for autistic people. Music therapy uses music experiences and the relationships that develop through them to enable communication and expression, thus attempting to address some of the core problems of autistic people. Music therapy has been applied in autism since the early 1950s, but its availability to autistic individuals varies across countries and settings. The application of music therapy requires specialised academic and clinical training which enables therapists to tailor the intervention to the specific needs of the individual. The present version of this review on music therapy for autistic people is an update of the previous Cochrane review update published in 2014 (following the original Cochrane review published in 2006).

OBJECTIVES

To review the effects of music therapy, or music therapy added to standard care, for autistic people.

SEARCH METHODS

In  August 2021, we searched  CENTRAL, MEDLINE, Embase, eleven other databases and two trials registers. We also ran citation searches, checked reference lists, and contacted study authors to identify additional studies.

SELECTION CRITERIA

All randomised controlled trials (RCTs), quasi-randomised trials and controlled clinical trials comparing music therapy (or music therapy alongside standard care) to 'placebo' therapy, no treatment, or standard care for people with a diagnosis of autism spectrum disorder were considered for inclusion.

DATA COLLECTION AND ANALYSIS

We used standard Cochrane methodological procedures. Four authors independently selected studies and extracted data from all included studies. We synthesised the results of included studies in meta-analyses. Four authors independently assessed risk of bias (RoB) of each included study using the original RoB tool as well as the certainty of evidence using GRADE.   MAIN RESULTS: We included 16 new studies in this update which brought the total number of included studies to 26 (1165 participants). These studies examined the short- and medium-term effect of music therapy (intervention duration: three days to eight months) for autistic people in individual or group settings. More than half of the studies were conducted in North America or Asia. Twenty-one studies included children aged from two to 12 years. Five studies included children and adolescents, and/or young adults. Severity levels, language skills, and cognition were widely variable across studies. Measured immediately post-intervention, music therapy compared with 'placebo' therapy or standard care was more likely to positively effect global improvement (risk ratio (RR) 1.22, 95% confidence interval (CI) 1.06 to 1.40; 8 studies, 583 participants; moderate-certainty evidence; number needed to treat for an additional beneficial outcome (NNTB) = 11 for low-risk population, 95% CI 6 to 39; NNTB = 6 for high-risk population, 95% CI 3 to 21) and to slightly increase quality of life (SMD 0.28, 95% CI 0.06 to 0.49; 3 RCTs, 340 participants; moderate-certainty evidence, small to medium effect size). In addition, music therapy probably results in a large reduction in total autism symptom severity (SMD -0.83, 95% CI -1.41 to -0.24; 9 studies, 575 participants; moderate-certainty evidence). No clear evidence of a difference between music therapy and comparison groups at immediately post-intervention was found for social interaction (SMD 0.26, 95% CI -0.05 to 0.57, 12 studies, 603 participants; low-certainty evidence); non-verbal communication (SMD 0.26, 95% CI -0.03 to 0.55; 7 RCTs, 192 participants; low-certainty evidence); and verbal communication (SMD 0.30, 95% CI -0.18 to 0.78; 8 studies, 276 participants; very low-certainty evidence). Two studies investigated adverse events with one (36 participants) reporting no adverse events; the other study found no differences between music therapy and standard care immediately post-intervention (RR 1.52, 95% CI 0.39 to 5.94; 1 study, 290 participants; moderate-certainty evidence).  AUTHORS' CONCLUSIONS: The findings of this updated review provide evidence that music therapy is probably associated with an increased chance of global improvement for autistic people, likely helps them to improve total autism severity and quality of life, and probably does not increase adverse events immediately after the intervention. The certainty of the evidence was rated as 'moderate' for these four outcomes, meaning that we are moderately confident in the effect estimate. No clear evidence of a difference was found for social interaction, non-verbal communication, and verbal communication measured immediately post-intervention. For these outcomes, the certainty of the evidence was rated as 'low' or 'very low', meaning that the true effect may be substantially different from these results. Compared with earlier versions of this review, the new studies included in this update helped to increase the certainty and applicability of this review's findings through larger sample sizes, extended age groups, longer periods of intervention and inclusion of follow-up assessments, and by predominantly using validated scales measuring generalised behaviour (i.e. behaviour outside of the therapy context). This new evidence is important for autistic individuals and their families as well as for policymakers, service providers and clinicians, to help in decisions around the types and amount of intervention that should be provided and in the planning of resources. The applicability of the findings is still limited to the age groups included in the studies, and no direct conclusions can be drawn about music therapy in autistic individuals above the young adult age. More research using rigorous designs, relevant outcome measures, and longer-term follow-up periods is needed to corroborate these findings and to examine whether the effects of music therapy are enduring.

The State of Music Therapy Studies in the Past 20 Years: A Bibliometric Analysis

Purpose: Music therapy is increasingly being used to address physical, emotional, cognitive, and social needs of individuals. However, publications on the global trends of music therapy using bibliometric analysis are rare. The study aimed to use the CiteSpace software to provide global scientific research about music therapy from 2000 to 2019.

Methods: Publications between 2000 and 2019 related to music therapy were searched from the Web of Science (WoS) database. The CiteSpace V software was used to perform co-citation analysis about authors, and visualize the collaborations between countries or regions into a network map. Linear regression was applied to analyze the overall publication trend.

Results: In this study, a total of 1,004 studies met the inclusion criteria. These works were written by 2,531 authors from 1,219 institutions. The results revealed that music therapy publications had significant growth over time because the linear regression results revealed that the percentages had a notable increase from 2000 to 2019 (t = 14.621, P < 0.001). The United States had the largest number of published studies (362 publications), along with the following outputs: citations on WoS (5,752), citations per study (15.89), and a high H-index value (37). The three keywords “efficacy,” “health,” and “older adults,” emphasized the research trends in terms of the strongest citation bursts.

Conclusions: The overall trend in music therapy is positive. The findings provide useful information for music therapy researchers to identify new directions related to collaborators, popular issues, and research frontiers. The development prospects of music therapy could be expected, and future scholars could pay attention to the clinical significance of music therapy to improve the quality of life of people.

Estimating Components and Costs of Standard Care for Children with Autism Spectrum Disorder in Europe from a Large International Sample

(1) Background: European guidelines provide recommendations for services and care for people with autism spectrum disorder (ASD), but not all interventions are generally available. Knowledge of service use and costs and wider societal costs in Europe is limited; (2) Method: Using an international sample, we analysed services and costs in 357 children (4-6.99 years) with ASD based on parent reports. Costs were transformed into EU-28 average using purchasing power parity; (3) Results: 122 children (34%) received specialist autism services; 149 (42%) received sensory/motor therapy; 205 (57%) received speech/language therapy; 35 (10%) received play therapy; 55 (15%) received behavioural interventions; 31 (9%) received social skills training; 47 (13%) participated in therapeutic recreational activities; and 59 (17%) received other services. The total number of hours for these services combined over two months was M = 34 (SD = 63; range: 0 -372). Estimated total costs of health-related services were M = 1210 EUR (SD = 2160 EUR); indirect societal costs were M = 1624 EUR (SD = 1317 EUR). Regression analyses suggested that costs rise with age and presence of intellectual disabilities, but not with severity of autism; (4) Conclusions: The high extent of community-based services indicates good accessibility but also considerable variation in the receipt of services. The costs of autism services are considerable. Further research is needed to investigate whether services received match individual needs.

Attunement in Music Therapy for Young Children with Autism: Revisiting Qualities of Relationship as Mechanisms of Change

This study examined whether musical and emotional attunement predicts changes in improvisational music therapy with children with autism (4–7 years, N = 101, majority: no/limited speech, low IQ), assessed over 12 months. Attunement, as observed from session videos, and changes in generalized social skills, judged by blinded assessors and parents, were evaluated using standardized tools (Assessment of the Quality of Relationship, Improvisational Music Therapy Principles, ADOS, SRS). In contrast to the smaller pilot, we did not find significant effects between attunement and changes in outcomes, only tendencies in the same direction are observed. Findings suggest that symptom severity is associated with the therapist’s ability to attune to the child. They further raise questions concerning outcome selection and user involvement.

Clinical and cost effectiveness of a parent mediated intervention to reduce challenging behaviour in pre-schoolers with moderate to severe intellectual disability (EPICC-ID) study protocol: a multi-centre, parallel-group randomised controlled trial

BACKGROUND

Children with intellectual disabilities are likely to present with challenging behaviour. Parent mediated interventions have shown utility in influencing child behaviour, although there is a paucity of UK research into challenging behaviour interventions in this population. NICE guidelines favour Stepping Stones Triple P (SSTP) as a challenging behaviour intervention and this trial aims to evaluate its clinical and cost effectiveness in preschool children with moderate to severe intellectual disabilities.

METHODS

This trial launched in 2017 at four sites across England, with the aim of recruiting 258 participants (aged 30-59 months). The Intervention Group receive nine weeks of SSTP parenting therapy (six group sessions and three individualised face to face or telephone sessions) in addition to Treatment as Usual, whilst the Treatment as Usual only group receive other available services in each location. Both study groups undergo the study measurements at baseline and at four and twelve months. Outcome measures include parent reports and structured observations of behaviour. Service use and health related quality of life data will also be collected to carry out a cost effectiveness and utility evaluation.

DISCUSSION

Findings from this study will inform policy regarding interventions for challenging behaviour in young children with moderate to severe intellectual disabilities.

Musical anhedonia and rewards of music listening: current advances and a proposed model

Music frequently elicits intense emotional responses, a phenomenon that has been scrutinized from multiple disciplines that span the sciences and arts. While most people enjoy music and find it rewarding, there is substantial individual variability in the experience and degree of music-induced reward. Here, we review current work on the neural substrates of hedonic responses to music. In particular, we focus the present review on specific musical anhedonia, a selective lack of pleasure from music. Based on evidence from neuroimaging, neuropsychology, and brain stimulation studies, we derive a neuroanatomical model of the experience of pleasure during music listening. Our model posits that hedonic responses to music are the result of connectivity between structures involved in auditory perception as a predictive process, and those involved in the brain's dopaminergic reward system. We conclude with open questions and implications of this model for future research on why humans appreciate music.

International multicentre randomised controlled trial of improvisational music therapy for children with autism spectrum disorder: TIME-A study

BACKGROUND

Preliminary studies have indicated that music therapy may benefit children with autism spectrum disorders (ASD).

OBJECTIVES

To examine the effects of improvisational music therapy (IMT) on social affect and responsiveness of children with ASD.

DESIGN

International, multicentre, three-arm, single-masked randomised controlled trial, including a National Institute for Health Research (NIHR)-funded centre that recruited in London and the east of England. Randomisation was via a remote service using permuted blocks, stratified by study site.

SETTING

Schools and private, voluntary and state-funded health-care services.

PARTICIPANTS

Children aged between 4 and 7 years with a confirmed diagnosis of ASD and a parent or guardian who provided written informed consent. We excluded children with serious sensory disorder and those who had received music therapy within the past 12 months.

INTERVENTIONS

All parents and children received enhanced standard care (ESC), which involved three 60-minute sessions of advice and support in addition to treatment as usual. In addition, they were randomised to either one (low-frequency) or three (high-frequency) sessions of IMT per week, or to ESC alone, over 5 months in a ratio of 1 : 1 : 2.

MAIN OUTCOME MEASURES

The primary outcome was measured using the social affect score derived from the Autism Diagnostic Observation Schedule (ADOS) at 5 months: higher scores indicated greater impairment. Secondary outcomes included social affect at 12 months and parent-rated social responsiveness at 5 and 12 months (higher scores indicated greater impairment).

RESULTS

A total of 364 participants were randomised between 2011 and 2015. A total of 182 children were allocated to IMT (90 to high-frequency sessions and 92 to low-frequency sessions), and 182 were allocated to ESC alone. A total of 314 (86.3%) of the total sample were followed up at 5 months [165 (90.7%) in the intervention group and 149 (81.9%) in the control group]. Among those randomised to IMT, 171 (94.0%) received it. From baseline to 5 months, mean scores of ADOS social affect decreased from 14.1 to 13.3 in music therapy and from 13.5 to 12.4 in standard care [mean difference: music therapy vs. standard care = 0.06, 95% confidence interval (CI) -0.70 to 0.81], with no significant difference in improvement. There were also no differences in the parent-rated social responsiveness score, which decreased from 96.0 to 89.2 in the music therapy group and from 96.1 to 93.3 in the standard care group over this period (mean difference: music therapy vs. standard care = -3.32, 95% CI -7.56 to 0.91). There were seven admissions to hospital that were unrelated to the study interventions in the two IMT arms compared with 10 unrelated admissions in the ESC group.

CONCLUSIONS

Adding IMT to the treatment received by children with ASD did not improve social affect or parent-assessed social responsiveness.

FUTURE WORK

Other methods for delivering music-focused interventions for children with ASD should be explored.

Effects of Improvisational Music Therapy vs Enhanced Standard Care on Symptom Severity Among Children With Autism Spectrum Disorder: The TIME-A Randomized Clinical Trial

IMPORTANCE

Music therapy may facilitate skills in areas affected by autism spectrum disorder (ASD), such as social interaction and communication.

OBJECTIVE

To evaluate effects of improvisational music therapy on generalized social communication skills of children with ASD.

DESIGN, SETTING, AND PARTICIPANTS

Assessor-blinded, randomized clinical trial, conducted in 9 countries and enrolling children aged 4 to 7 years with ASD. Children were recruited from November 2011 to November 2015, with follow-up between January 2012 and November 2016.

INTERVENTIONS

Enhanced standard care (n = 182) vs enhanced standard care plus improvisational music therapy (n = 182), allocated in a 1:1 ratio. Enhanced standard care consisted of usual care as locally available plus parent counseling to discuss parents' concerns and provide information about ASD. In improvisational music therapy, trained music therapists sang or played music with each child, attuned and adapted to the child's focus of attention, to help children develop affect sharing and joint attention.

MAIN OUTCOMES AND MEASURES

The primary outcome was symptom severity over 5 months, based on the Autism Diagnostic Observation Schedule (ADOS), social affect domain (range, 0-27; higher scores indicate greater severity; minimal clinically important difference, 1). Prespecified secondary outcomes included parent-rated social responsiveness. All outcomes were also assessed at 2 and 12 months.

RESULTS

Among 364 participants randomized (mean age, 5.4 years; 83% boys), 314 (86%) completed the primary end point and 290 (80%) completed the last end point. Over 5 months, participants assigned to music therapy received a median of 19 music therapy, 3 parent counseling, and 36 other therapy sessions, compared with 3 parent counseling and 45 other therapy sessions for those assigned to enhanced standard care. From baseline to 5 months, mean ADOS social affect scores estimated by linear mixed-effects models decreased from 14.08 to 13.23 in the music therapy group and from 13.49 to 12.58 in the standard care group (mean difference, 0.06 [95% CI, -0.70 to 0.81]; P = .88), with no significant difference in improvement. Of 20 exploratory secondary outcomes, 17 showed no significant difference.

CONCLUSIONS AND RELEVANCE

Among children with autism spectrum disorder, improvisational music therapy, compared with enhanced standard care, resulted in no significant difference in symptom severity based on the ADOS social affect domain over 5 months. These findings do not support the use of improvisational music therapy for symptom reduction in children with autism spectrum disorder.

Interventions Targeting Sensory Challenges in Autism Spectrum Disorder: A Systematic Review

CONTEXT

Sensory challenges are common among children with autism spectrum disorder (ASD).

OBJECTIVE

To evaluate the effectiveness and safety of interventions targeting sensory challenges in ASD.

DATA SOURCES

Databases, including Medline and PsycINFO.

STUDY SELECTION

Two investigators independently screened studies against predetermined criteria.

DATA EXTRACTION

One investigator extracted data with review by a second. Investigators independently assessed risk of bias and strength of evidence (SOE), or confidence in the estimate of effects.

RESULTS

Twenty-four studies, including 20 randomized controlled trials (RCTs), were included. Only 3 studies had low risk of bias. Populations, interventions, and outcomes varied. Limited, short-term studies reported potential positive effects of several approaches in discrete skill domains. Specifically, sensory integration-based approaches improved sensory and motor skills-related measures (low SOE). Environmental enrichment improved nonverbal cognitive skills (low SOE). Studies of auditory integration-based approaches did not improve language (low SOE). Massage improved symptom severity and sensory challenges in studies with likely overlapping participants (low SOE). Music therapy studies evaluated different protocols and outcomes, precluding synthesis (insufficient SOE). Some positive effects were reported for other approaches, but findings were inconsistent (insufficient SOE).

LIMITATIONS

Studies were small and short-term, and few fully categorized populations.

CONCLUSIONS

Some interventions may yield modest short-term (<6 months) improvements in sensory- and ASD symptom severity-related outcomes; the evidence base is small, and the durability of the effects is unclear. Although some therapies may hold promise, substantial needs exist for continuing improvements in methodologic rigor.

The first ‘themed’ British journal of music therapy: An introduction to music therapy with families

This essay introduces the reader to the subject of music therapy with families and explains how this area of clinical practice has developed as well as seeking to understand why it has evolved in this way. It gives an overview of the current literature on the subject and introduces the content of this Special Edition. Scenes from two current clinical vignettes are described, and clinical material is presented that illustrates emerging trends, theories and characteristics of music therapy with families.

Effects of active music therapy on the normal brain: fMRI based evidence

The aim of this study was to investigate the neurophysiological bases of Active Music Therapy (AMT) and its effects on the normal brain. Twelve right-handed, healthy, non-musician volunteers were recruited. The subjects underwent 2 AMT sessions based on the free sonorous-music improvisation using rhythmic and melodic instruments. After these sessions, each subject underwent 2 fMRI scan acquisitions while listening to a Syntonic (SP) and an A-Syntonic (AP) Production from the AMT sessions. A 3 T Discovery MR750 scanner with a 16-channel phased array head coil was used, and the image analysis was performed with Brain Voyager QX 2.8. The listening to SP vs AP excerpts mainly activated: (1) the right middle temporal gyrus and right superior temporal sulcus, (2) the right middle frontal gyrus and in particular the right precentral gyrus, (3) the bilateral precuneus, (4) the left superior temporal sulcus and (5) the left middle temporal gyrus. These results are consistent with the psychological bases of the AMT approach and with the activation of brain areas involved in memory and autobiographical processes, and also in personal or interpersonal significant experiences. Further studies are required to confirm these findings and to explain possible effects of AMT in clinical settings.

The role, function and identity of music therapists in the 21st century, including new research and thinking from a UK perspective

This article examines the identity of music therapy and music therapists, focussing upon the United Kingdom as a case study, but also considering international trends. Milestones in the history of music therapy in postwar United Kingdom and professional development in the 21st century are discussed, drawing upon research and clinical practice. Research outcomes across different specialities indicate that music therapy should be widely available to many populations, such as for people with dementia, autism, stroke and mental health problems and so on. These advancements mean that music therapists need to be clear about their role and identity in both doing the work and communicating about it. The article celebrates advances in research, thinking and provision and emphasis collaboration across multidisciplinary groups through an overview of different identities.

The challenges and benefits of a genuine partnership between Music Therapy and Neuroscience: a dialog between scientist and therapist

Collaborations between neuroscience and music therapy promise many mutual benefits given the different knowledge bases, experiences and specialist skills possessed by each discipline. Primarily, music therapists deliver music-based interventions on a daily basis with numerous populations; neuroscientists measure clinical changes in ways that provide an evidence base for progressing clinical care. Although recent developments suggest that partnerships between the two can produce positive outcomes for both fields, these collaborations are not considered mainstream. The following dialog between an experienced professional from each discipline explores the potential for collaboration, as well as the misconceptions that may be preventing further synergies from developing.

Music therapy for people with autism spectrum disorder

BACKGROUND

The central impairments of people with autism spectrum disorder (ASD) affect social interaction and communication. Music therapy uses musical experiences and the relationships that develop through them to enable communication and expression, thus attempting to address some of the core problems of people with ASD. The present version of this review on music therapy for ASD is an update of the original Cochrane review published in 2006.

OBJECTIVES

To assess the effects of music therapy for individuals with ASD.

SEARCH METHODS

We searched the following databases in July 2013: CENTRAL, Ovid MEDLINE, EMBASE, LILACS, PsycINFO, CINAHL, ERIC, ASSIA, Sociological Abstracts, and Dissertation Abstracts International. We also checked the reference lists of relevant studies and contacted investigators in person.

SELECTION CRITERIA

All randomised controlled trials (RCTs) or controlled clinical trials comparing music therapy or music therapy added to standard care to 'placebo' therapy, no treatment, or standard care for individuals with ASD were considered for inclusion.

DATA COLLECTION AND ANALYSIS

Two authors independently selected studies, assessed risk of bias, and extracted data from all included studies. We calculated the pooled standardised mean difference (SMD) and corresponding 95% confidence interval (CI) for continuous outcomes to allow the combination data from different scales and to facilitate the interpretation of effect sizes. Heterogeneity was assessed using the I² statistic. In cases of statistical heterogeneity within outcome subgroups, we examined clients' age, intensity of therapy (number and frequency of therapy sessions), and treatment approach as possible sources of heterogeneity.

MAIN RESULTS

We included 10 studies (165 participants) that examined the short- and medium-term effect of music therapy interventions (one week to seven months) for children with ASD. Music was superior to 'placebo' therapy or standard care with respect to the primary outcomes social interaction within the therapy context (SMD 1.06, 95% CI 0.02 to 2.10, 1 RCT, n = 10); generalised social interaction outside of the therapy context (SMD 0.71, 95% CI 0.18 to 1.25, 3 RCTs, n = 57, moderate quality evidence), non-verbal communicative skills within the therapy context (SMD 0.57, 95% CI 0.29 to 0.85, 3 RCTs, n = 30), verbal communicative skills (SMD 0.33, 95% CI 0.16 to 0.49, 6 RCTs, n = 139), initiating behaviour (SMD 0.73, 95% CI 0.36 to 1.11, 3 RCTs, n = 22, moderate quality evidence), and social-emotional reciprocity (SMD 2.28, 95% CI 0.73 to 3.83, 1 RCT, n = 10, low quality evidence). There was no statistically significant difference in non-verbal communicative skills outside of the therapy context (SMD 0.48, 95% CI -0.02 to 0.98, 3 RCTs, n = 57, low quality evidence). Music therapy was also superior to 'placebo' therapy or standard care in secondary outcome areas, including social adaptation (SMD 0.41, 95% CI 0.21 to 0.60, 4 RCTs, n = 26), joy (SMD 0.96, 95% CI 0.04 to 1.88, 1 RCT, n = 10), and quality of parent-child relationships (SMD 0.82, 95% CI 0.13 to 1.52, 2 RCTs, n = 33, moderate quality evidence). None of the included studies reported any adverse effects. The small sample sizes of the studies limit the methodological strength of these findings.

AUTHORS' CONCLUSIONS

The findings of this updated review provide evidence that music therapy may help children with ASD to improve their skills in primary outcome areas that constitute the core of the condition including social interaction, verbal communication, initiating behaviour, and social-emotional reciprocity. Music therapy may also help to enhance non-verbal communication skills within the therapy context. Furthermore, in secondary outcome areas, music therapy may contribute to increasing social adaptation skills in children with ASD and to promoting the quality of parent-child relationships. In contrast to the studies included in an earlier version of this review published in 2006, the new studies included in this update enhanced the applicability of findings to clinical practice. More research using larger samples and generalised outcome measures is needed to corroborate these findings and to examine whether the effects of music therapy are enduring. When applying the results of this review to practice, it is important to note that the application of music therapy requires specialised academic and clinical training.

Psychiatry and music

Vocal and/or instrumental sounds combined in such a way as to produce beauty of form, harmony and expression of emotion is music. Brain, mind and music are remarkably related to each other and music has got a strong impact on psychiatry. With the advent of music therapy, as an efficient form of alternative therapy in treating major psychiatric conditions, this impact has been further strengthened. In this review, we deliberate upon the historical aspects of the relationship between psychiatry and music, neural processing underlying music, music's relation to classical psychology and psychopathology and scientific evidence base for music therapy in major psychiatric disorders. We highlight the role of Indian forms of music and Indian contribution to music therapy.

Interventions based on the Theory of Mind cognitive model for autism spectrum disorder (ASD)

BACKGROUND

The 'Theory of Mind' (ToM) model suggests that people with autism spectrum disorder (ASD) have a profound difficulty understanding the minds of other people - their emotions, feelings, beliefs, and thoughts. As an explanation for some of the characteristic social and communication behaviours of people with ASD, this model has had a significant influence on research and practice. It implies that successful interventions to teach ToM could, in turn, have far-reaching effects on behaviours and outcome.

OBJECTIVES

To review the efficacy of interventions based on the ToM model for individuals with ASD.

SEARCH METHODS

In August 2013 we searched CENTRAL, Ovid MEDLINE, Embase, CINAHL, PsycINFO, ERIC, Social Services Abstracts, AutismData, and two trials registers. We also searched the reference lists of relevant papers, contacted authors who work in this field, and handsearched a number of journals.

SELECTION CRITERIA

Review studies were selected on the basis that they reported on an applicable intervention (linked to ToM in one of four clearly-defined ways), presented new randomised controlled trial data, and participants had a confirmed diagnosis of an autism spectrum disorder. Studies were selected by two review authors independently and a third author arbitrated when necessary.

DATA COLLECTION AND ANALYSIS

Risk of bias was evaluated and data were extracted by two review authors independently; a third author arbitrated when necessary. Most studies were not eligible for meta-analysis, the principal reason being mis-matching methodologies and outcome measures. Three small meta-analyses were carried out.

MAIN RESULTS

Twenty-two randomised trials were included in the review (N = 695). Studies were highly variable in their country of origin, sample size, participant age, intervention delivery type, and outcome measures. Risk of bias was variable across categories. There were very few studies for which there was adequate blinding of participants and personnel, and some were also judged at high risk of bias in blinding of outcome assessors. There was also evidence of some bias in sequence generation and allocation concealment. Not all studies reported data that fell within the pre-defined primary outcome categories for the review, instead many studies reported measures which were intervention-specific (e.g. emotion recognition). The wide range of measures used within each outcome category and the mixed results from these measures introduced further complexity when interpreting results.Studies were grouped into four main categories according to intervention target/primary outcome measure. These were: emotion recognition studies, joint attention and social communication studies, imitation studies, and studies teaching ToM itself. Within the first two of these categories, a sub-set of studies were deemed suitable for meta-analysis for a limited number of key outcomes.There was very low quality evidence of a positive effect on measures of communication based on individual results from three studies. There was low quality evidence from 11 studies reporting mixed results of interventions on measures of social interaction, very low quality evidence from four studies reporting mixed results on measures of general communication, and very low quality evidence from four studies reporting mixed results on measures of ToM ability.  The meta-analysis results we were able to generate showed that interventions targeting emotion recognition across age groups and working with people within the average range of intellectual ability had a positive effect on the target skill, measured by a test using photographs of faces (mean increase of 0.75 points, 95% confidence interval (CI) 0.22 to 1.29 points, Z = 2.75, P < 0.006, four studies, N = 105). Therapist-led joint attention interventions can promote production of more joint attention behaviours within adult-child interaction (mean increase of 0.55 points, 95% CI 0.11 to 0.99 points, Z = 2.45, P value = 0.01, two studies, N = 88). Further analysis undermines this conclusion somewhat by demonstrating that there was no clear evidence that intervention can have an effect on joint attention initiations as measured using a standardised assessment tool (mean increase of 0.23 points, 95% CI -0.48 to 0.94 points, Z = 0.63, P value = 0.53, three studies, N = 92). No adverse effects were apparent.

AUTHORS' CONCLUSIONS

While there is some evidence that ToM, or a precursor skill, can be taught to people with ASD, there is little evidence of maintenance of that skill, generalisation to other settings, or developmental effects on related skills. Furthermore, inconsistency in findings and measurement means that evidence has been graded of 'very low' or 'low' quality and we cannot be confident that suggestions of positive effects will be sustained as high-quality evidence accumulates. Further longitudinal designs and larger samples are needed to help elucidate both the efficacy of ToM-linked interventions and the explanatory value of the ToM model itself. It is possible that the continuing refinement of the ToM model will lead to better interventions which have a greater impact on development than those investigated to date.

Individual music therapy for mental health care clients with low therapy motivation: multicentre randomised controlled trial

BACKGROUND

Music therapy (MT) has been shown to be efficacious for mental health care clients with various disorders such as schizophrenia, depression and substance abuse. Referral to MT in clinical practice is often based on other factors than diagnosis. We aimed to examine the effectiveness of resource-oriented MT for mental health care clients with low motivation for other therapies.

METHOD

This was a pragmatic parallel trial. In specialised centres in Norway, Austria and Australia, 144 adults with non-organic mental disorders and low therapy motivation were randomised to 3 months of biweekly individual, resource-oriented MT plus treatment as usual (TAU) or TAU alone. TAU was typically intensive (71% were inpatients) and included the best combination of therapies available for each participant, excluding MT. Blinded assessments of the Scale for the Assessment of Negative Symptoms (SANS) and 15 secondary outcomes were collected before randomisation and after 1, 3 and 9 months. Changes were analysed on an intention-to-treat basis using generalised estimating equations in longitudinal linear models, controlling for diagnosis, site and time point.

RESULTS

MT was superior to TAU for total negative symptoms (SANS, d = 0.54, p < 0.001) as well as functioning, clinical global impressions, social avoidance through music, and vitality (all p < 0.01).

CONCLUSION

Individual MT as conducted in routine practice is an effective addition to usual care for mental health care clients with low motivation.
