The effectiveness of music therapy in group psychotherapy for adults with mental illness

Music therapy in the early detection and indicated prevention in persons at risk of bipolar disorders: State of knowledge and potential

Bipolar disorders are among the most severe mental illnesses. The onset of the disorder is frequently preceded by phases with subsyndromal symptoms. In Germany, psychiatric early detection centres provide prevention services for help-seeking young people which focus on risk research. This article considers how music therapy contributes to the indicated prevention of bipolar disorders in preparation for a qualitative research study. The article presents a narrative literature review on research into early detection and prediction in bipolar disorders and approaches to prevention. The rationale for the use of music therapy in this context is discussed, with consideration of research questions leading to the next stage of the study.

Effects of progressive muscle relaxation training with music therapy on sleep and anger of patients at Community Mental Health Center

OBJECTIVE

The objective is to examine the effects of progressive muscle relaxation training and music therapy applied to chronic psychiatric patients attending the Community Mental Health Center (CMHC) on their anger level and sleep quality.

METHODS

The sample of the study consisted of 66 chronic psychiatric patients (n = 32 in the control group; n = 34 in the intervention group). Progressive muscle relaxation training with music therapy were implemented in the intervention group as 2 sessions per week for 3 months.

RESULTS

A statistically significant difference was found between the pre-test and post-test mean scores of the intervention group (p ≤ .001). After the intervention, a statistically significant difference was found between the PSQI, anger-in, anger-out, anger-control, and trait anger scale scores of the two groups (p ≤ .001).

CONCLUSION

Relaxation training and music therapy are effective in controlling anger and increasing sleep quality in chronic psychiatric patients.

The link between detail generation and eye movements when encoding and retrieving complex images

Examining eye movement patterns when encoding and retrieving visually complex memories is useful to understand the link between visuo-perceptual processes and how associated details are represented within these memories. Here, we used images of real-world scenes (e.g., a couple grocery shopping) to examine how encoding and retrieval eye movements are linked to the details used to describe complex images during these two phases of memory. Given that memories are often elaborated upon during retrieval, we also examined whether eye-movements at retrieval related to details that were the same as those described when encoding the image (reinstated details) as well as details about the image event that were not initially described at encoding (newly generated details). Testing young healthy participants, we found that retrieval eye movements, specifically eye fixation rate, predicted reinstated details, but not newly generated details. This suggests that visuo-perceptual processes are preferentially engaged at retrieval to reactivate perceived information. At encoding, we found a relationship between eye movements and detail generation that changed over time. This relationship was positive early on in the encoding phase but changed to a negative relationship later in the phase, indicating that a unique relationship exists between activating visuo-perceptual processes during early encoding versus late encoding. Overall, our results provide new insights into how visuo-perceptual processes contribute to different components of complex memory.

Sound practice: Exploring the benefits of establishing a music group on an acute mental health inpatient unit

There is evidence supporting the use of formal music therapy in the treatment of mental health consumers. Despite this, it appears to be an intervention which has not been routinely offered to consumers in Australian acute mental health inpatient units, possibly due to the lack of trained music therapists (or inadequate funding to employ them), as well as the challenges posed by the acuity of presentations and the short duration of admissions. Less formal therapeutic music activities may benefit consumers within these settings. This article describes how a music group activity facilitated by clinical staff with no music therapy qualifications was established. The first phase of this evaluation is then described using a descriptive qualitative method. We undertook a series of consumer and staff focus groups to explore the impact of a music group activity on an acute mental health inpatient unit. Five themes emerged from the transcripts of the focus groups' discussions, effects on mood, relationships and engagement, social connectedness and inclusion, the ward atmosphere and noise/agitation. Positive effects were shown across these areas, suggesting that the music group activity we established was beneficial for consumers and staff, and enhanced the ward atmosphere.

"Summer is you": Adolescents and young adults with cancer sing about their desire for summer

Creative spirit and art are used as part of the Youth Project in Milan, a program dedicated to adolescents and young adults (AYA) with cancer. The "Summer is you" music project involved 45 patients (15-26 years old): with professional help, the patients wrote music and lyrics, sang their song, and recorded a video clip, sharing with us not only their hopes and fears, but also their romantic encounters and their urge to travel (https://youtu.be/Q5FSCMUVg0E). This project exploited the power of music to bring young people with cancer together in a novel form of support that can complement the more conventional psychological approaches.

Music therapy for people with schizophrenia and schizophrenia-like disorders

BACKGROUND

Music therapy is a therapeutic approach that uses musical interaction as a means of communication and expression. Within the area of serious mental disorders, the aim of the therapy is to help people improve their emotional and relational competencies, and address issues they may not be able to using words alone.

OBJECTIVES

To review the effects of music therapy, or music therapy added to standard care, compared with placebo therapy, standard care or no treatment for people with serious mental disorders such as schizophrenia.

SEARCH METHODS

We searched the Cochrane Schizophrenia Group's Trials Study-Based Register (December 2010 and 15 January, 2015) and supplemented this by contacting relevant study authors, handsearching of music therapy journals and manual searches of reference lists.

SELECTION CRITERIA

All randomised controlled trials (RCTs) that compared music therapy with standard care, placebo therapy, or no treatment.

DATA COLLECTION AND ANALYSIS

Review authors independently selected, quality assessed and data extracted studies. We excluded data where more than 30% of participants in any group were lost to follow-up. We synthesised non-skewed continuous endpoint data from valid scales using a standardised mean difference (SMD). We employed a fixed-effect model for all analyses. If statistical heterogeneity was found, we examined treatment dosage (i.e. number of therapy sessions) and treatment approach as possible sources of heterogeneity.

MAIN RESULTS

Ten new studies have been added to this update; 18 studies with a total 1215 participants are now included. These examined effects of music therapy over the short, medium, and long-term, with treatment dosage varying from seven to 240 sessions. Overall, most information is from studies at low or unclear risk of biasA positive effect on global state was found for music therapy compared to standard care (medium term, 2 RCTs, n = 133, RR 0.38 95% confidence interval (CI) 0.24 to 0.59, low-quality evidence, number needed to treat for an additional beneficial outcome NNTB 2, 95% CI 2 to 4). No binary data were available for other outcomes. Medium-term continuous data identified good effects for music therapy on negative symptoms using the Scale for the Assessment of Negative Symptoms (3 RCTs, n = 177, SMD - 0.55 95% CI -0.87 to -0.24, low-quality evidence). General mental state endpoint scores on the Positive and Negative Symptoms Scale were better for music therapy (2 RCTs, n = 159, SMD -0.97 95% CI -1.31 to -0.63, low-quality evidence), as were average endpoint scores on the Brief Psychiatric Rating Scale (1 RCT, n = 70, SMD -1.25 95% CI -1.77 to -0.73, moderate-quality evidence). Medium-term average endpoint scores using the Global Assessment of Functioning showed no effect for music therapy on general functioning (2 RCTs, n = 118, SMD -0.19 CI -0.56 to 0.18, moderate-quality evidence). However, positive effects for music therapy were found for both social functioning (Social Disability Screening Schedule scores; 2 RCTs, n = 160, SMD -0.72 95% CI -1.04 to -0.40), and quality of life (General Well-Being Schedule scores: 1 RCT, n = 72, SMD 1.82 95% CI 1.27 to 2.38, moderate-quality evidence). There were no data available for adverse effects, service use, engagement with services, or cost.

AUTHORS' CONCLUSIONS

Moderate- to low-quality evidence suggests that music therapy as an addition to standard care improves the global state, mental state (including negative and general symptoms), social functioning, and quality of life of people with schizophrenia or schizophrenia-like disorders. However, effects were inconsistent across studies and depended on the number of music therapy sessions as well as the quality of the music therapy provided. Further research should especially address the long-term effects of music therapy, dose-response relationships, as well as the relevance of outcome measures in relation to music therapy.

Drawing and Drumming

This article describes a pilot open art and music therapy group which took place on an assessment ward in a Medium Secure Unit for patients detained under the UK's Mental Health Act. The aim was to offer an optional therapeutic space to patients who had limited access to off-ward therapy and activities, and to see whether this would be of value in this setting.

The ward environment is described, the need for on-ward therapy outlined and relevant literature surveyed The planning, setting up and evaluation of two phases of the work are then detailed, with particular focus on the rationale for the ways in which sessions were run and the roles of the two therapists (one a music therapist, the other an art therapist). Changing group membership and its impact on the therapy is described, and modifications to the original approach explained.

Feedback from staff and patients is presented and discussed, leading to reflections on the value of this kind of therapeutic experience in such a setting.

"The Opposite of Treatment": A qualitative study of how patients diagnosed with psychosis experience music therapy

Previous research studies regarding music therapy and severe mental illness have mainly adopted quantitative methodologies in order to study the effectiveness of music therapy interventions. Studies that have explored service users' experiences of participation in music therapy are small in number, and almost nonexistent in the field of psychosis. This study aimed to explore how mental health patients with a diagnosis of psychosis experienced participation in music therapy, in general, and more specifically how they experienced music therapy in relation to their current mental state and life situation. Nine inpatients with psychosis were interviewed using a semi-structured interview focusing on the participants' experiences of music therapy in individual sessions, groups, and performances. Through the use of interpretative phenomenological analysis, four super-ordinate themes central to the participants' experiences were found: freedom, contact, well-being, and symptom reduction. Based on the findings, mental health recovery, positive mental health, and agency are proposed as constituting a better framework for music therapy in mental healthcare than a primary focus on symptom remission and functional improvement.

The use of art and music therapy in substance abuse treatment programs

Although the implementation of evidence-based practices in the treatment of substance use disorders has attracted substantial research attention, little consideration has been given to parallel implementation of complementary and alternative medical (CAM) practices. Using data from a nationally representative sample (N = 299) of U.S. substance abuse treatment programs, this study modeled organizational factors falling in the domains of patient characteristics, treatment ideologies, and structural characteristics, associated with the use of art therapy and music therapy. We found that 36.8% of treatment programs offered art therapy and 14.7% of programs offered music therapy. Programs with a greater proportion of women were more likely to use both therapies, and programs with larger proportions of adolescents were more likely to offer music therapy. In terms of other treatment ideologies, programs' use of Motivational Enhancement Therapy was positively related to offering art therapy, whereas use of contingency management was positively associated with offering music therapy. Finally, our findings showed a significant relationship between requiring 12-step meetings and the use of both art therapy and music therapy. With increasing use of CAM in a diverse range of medical settings and recent federal legislation likely to reduce barriers in accessing CAM, the inclusion of CAM in addiction treatment is growing in importance. Our findings suggest treatment programs may be utilizing art and music therapies to address unique patient needs of women and adolescents.

Group music therapy for severe mental illness: a randomized embedded-experimental mixed methods study

OBJECTIVE

Music therapy is an innovative approach to support people with severe mental illness (SMI). The aim of the study was to determine whether group music therapy (GMT) positively impacted on quality of life (QoL), social enrichment, self-esteem, spirituality and psychiatric symptoms of participants with SMI and how they experienced the intervention.

METHOD

The primary outcome was QoL; secondary measures assessed social enrichment, self-esteem, spirituality and psychiatric symptoms. The 13-week intervention comprised singing familiar songs and composing original songs recorded in a professional studio. Qualitative data were generated from focus group interviews and song lyric analysis.

RESULTS

Ninety-nine adults (57 female) were recruited, with an initial cohort (n = 75) randomized to either: weekly GMT followed by standard care (SC) or SC followed by GMT. Crossover occurred after 13 weeks. Measures were conducted at baseline, 13, 26 and 39 weeks. A second cohort (n = 24) could not be randomized and were assigned to GMT followed by SC. Intention-to-treat analysis showed a significant difference between GMT and SC on QoL and spirituality. This was robust to different assumptions about missing data (listwise deletion, last observation carried forward or multiple imputation). Per-protocol analysis suggested greater benefit for those receiving more sessions. Focus group interview and song lyric analyses suggested that GMT was enjoyable; self-esteem was enhanced; participants appreciated therapists and peers; and although challenges were experienced, the programme was recommended to others.

CONCLUSION

Group music therapy may enhance QoL and spirituality of persons with SMI.

Music therapy and music medicine for children and adolescents

This article summarizes the research on music therapy and music medicine for children and adolescents with diagnoses commonly treated by psychiatrists. Music therapy and music medicine are defined, effects of music on the brain are described, and music therapy research in psychiatric treatment is discussed. Music therapy research with specific child/adolescent populations is summarized, including disorders usually diagnosed in childhood, substance abuse, mood/anxiety disorders, and eating disorders. Clinical implications are listed, including suggestions for health care professionals seeking to use music medicine techniques. Strengths and weaknesses of music therapy treatment are discussed, as well as areas for future research.

Music therapy in the treatment and management of mental disorders

Objectives: An increasing number of research studies support the benefits of providing music therapy in addition to standard treatment for people who have mental disorders. The objective of this paper was to review and summarise recent research findings in relation to this work.

Method: A review of music therapy studies published since 1994 was undertaken. Criteria for including papers were that they a) were published in English in an indexed, peer-reviewed journal, and b) were conducted as a randomised controlled trial (RCT) or a controlled trial (CT), or c) provided a meta-analysis of existing studies. The large number of papers pertaining to music therapy for older adults who have mental disorders, including Alzheimer's disease and other types of dementia was not included.

Results: The findings support a role for music therapy as a structured interaction that patients are able to use to participate successfully, manage some of their symptoms, and express feelings relating to their experiences. Music therapy is demonstrated to be a beneficial intervention for people who have enduring mental illness. Music therapy invites and encourages participation from people of lower functioning levels and employs a non-verbal medium with which people have prior positive associations and in most cases have lifelong experience of using music for self-expression and pleasure. Additionally, the available peer reviewed literature supports the proposition that clinical outcomes are available through the use of music therapy intervention in conjunction with standard, well-established treatment methods.

Conclusions: Music therapy is beneficial for patients receiving care for mental disorders and establishing this therapy within mental health service provision should be considered.

Sensory environment on health-related outcomes of hospital patients

BACKGROUND

Hospital environments have recently received renewed interest, with considerable investments into building and renovating healthcare estates. Understanding the effectiveness of environmental interventions is important for resource utilisation and providing quality care.

OBJECTIVES

To assess the effect of hospital environments on adult patient health-related outcomes.

SEARCH METHODS

We searched: the Cochrane Central Register of Controlled Trials (last searched January 2006); MEDLINE (1902 to December 2006); EMBASE (January 1980 to February 2006); 14 other databases covering health, psychology, and the built environment; reference lists; and organisation websites. This review is currently being updated (MEDLINE last search October 2010), see Studies awaiting classification.

SELECTION CRITERIA

Randomised and non-randomised controlled trials, controlled before-and-after studies, and interrupted times series of environmental interventions in adult hospital patients reporting health-related outcomes.

DATA COLLECTION AND ANALYSIS

Two review authors independently undertook data extraction and 'Risk of bias' assessment. We contacted authors to obtain missing information. For continuous variables, we calculated a mean difference (MD) or standardized mean difference (SMD), and 95% confidence intervals (CI) for each study. For dichotomous variables, we calculated a risk ratio (RR) with 95% confidence intervals (95% CI). When appropriate, we used a random-effects model of meta-analysis. Heterogeneity was explored qualitatively and quantitatively based on risk of bias, case mix, hospital visit characteristics, and country of study.

MAIN RESULTS

Overall, 102 studies have been included in this review. Interventions explored were: 'positive distracters', to include aromas (two studies), audiovisual distractions (five studies), decoration (one study), and music (85 studies); interventions to reduce environmental stressors through physical changes, to include air quality (three studies), bedroom type (one study), flooring (two studies), furniture and furnishings (one study), lighting (one study), and temperature (one study); and multifaceted interventions (two studies). We did not find any studies meeting the inclusion criteria to evaluate: art, access to nature for example, through hospital gardens, atriums, flowers, and plants, ceilings, interventions to reduce hospital noise, patient controls, technologies, way-finding aids, or the provision of windows. Overall, it appears that music may improve patient-reported outcomes such as anxiety; however, the benefit for physiological outcomes, and medication consumption has less support. There are few studies to support or refute the implementation of physical changes, and except for air quality, the included studies demonstrated that physical changes to the hospital environment at least did no harm.

AUTHORS' CONCLUSIONS

Music may improve patient-reported outcomes in certain circumstances, so support for this relatively inexpensive intervention may be justified. For some environmental interventions, well designed research studies have yet to take place.

Music therapy for people with schizophrenia and schizophrenia-like disorders

BACKGROUND

Music therapy is a therapeutic method that uses musical interaction as a means of communication and expression. The aim of the therapy is to help people with serious mental disorders to develop relationships and to address issues they may not be able to using words alone.

OBJECTIVES

To review the effects of music therapy, or music therapy added to standard care, compared with 'placebo' therapy, standard care or no treatment for people with serious mental disorders such as schizophrenia.

SEARCH METHODS

We searched the Cochrane Schizophrenia Group Trials Register (December 2010) and supplemented this by contacting relevant study authors, handsearching of music therapy journals and manual searches of reference lists.

SELECTION CRITERIA

All randomised controlled trials (RCTs) that compared music therapy with standard care, placebo therapy, or no treatment.

DATA COLLECTION AND ANALYSIS

Studies were reliably selected, quality assessed and data extracted. We excluded data where more than 30% of participants in any group were lost to follow-up. We synthesised non-skewed continuous endpoint data from valid scales using a standardised mean difference (SMD). If statistical heterogeneity was found, we examined treatment 'dosage' and treatment approach as possible sources of heterogeneity.

MAIN RESULTS

We included eight studies (total 483 participants). These examined effects of music therapy over the short- to medium-term (one to four months), with treatment 'dosage' varying from seven to 78 sessions. Music therapy added to standard care was superior to standard care for global state (medium-term, 1 RCT, n = 72, RR 0.10 95% CI 0.03 to 0.31, NNT 2 95% CI 1.2 to 2.2). Continuous data identified good effects on negative symptoms (4 RCTs, n = 240, SMD average endpoint Scale for the Assessment of Negative Symptoms (SANS) -0.74 95% CI -1.00 to -0.47); general mental state (1 RCT, n = 69, SMD average endpoint Positive and Negative Symptoms Scale (PANSS) -0.36 95% CI -0.85 to 0.12; 2 RCTs, n=100, SMD average endpoint Brief Psychiatric Rating Scale (BPRS) -0.73 95% CI -1.16 to -0.31); depression (2 RCTs, n = 90, SMD average endpoint Self-Rating Depression Scale (SDS) -0.63 95% CI -1.06 to -0.21; 1 RCT, n = 30, SMD average endpoint Hamilton Depression Scale (Ham-D) -0.52 95% CI -1.25 to -0.21 ); and anxiety (1 RCT, n = 60, SMD average endpoint SAS -0.61 95% CI -1.13 to -0.09). Positive effects were also found for social functioning (1 RCT, n = 70, SMD average endpoint Social Disability Schedule for Inpatients (SDSI) score -0.78 95% CI -1.27 to -0.28). Furthermore, some aspects of cognitive functioning and behaviour seem to develop positively through music therapy. Effects, however, were inconsistent across studies and depended on the number of music therapy sessions as well as the quality of the music therapy provided.

AUTHORS' CONCLUSIONS

Music therapy as an addition to standard care helps people with schizophrenia to improve their global state, mental state (including negative symptoms) and social functioning if a sufficient number of music therapy sessions are provided by qualified music therapists. Further research should especially address the long-term effects of music therapy, dose-response relationships, as well as the relevance of outcomes measures in relation to music therapy.

Dose-response relationship in music therapy for people with serious mental disorders: systematic review and meta-analysis

Serious mental disorders have considerable individual and societal impact, and traditional treatments may show limited effects. Music therapy may be beneficial in psychosis and depression, including treatment-resistant cases. The aim of this review was to examine the benefits of music therapy for people with serious mental disorders. All existing prospective studies were combined using mixed-effects meta-analysis models, allowing to examine the influence of study design (RCT vs. CCT vs. pre-post study), type of disorder (psychotic vs. non-psychotic), and number of sessions. Results showed that music therapy, when added to standard care, has strong and significant effects on global state, general symptoms, negative symptoms, depression, anxiety, functioning, and musical engagement. Significant dose-effect relationships were identified for general, negative, and depressive symptoms, as well as functioning, with explained variance ranging from 73% to 78%. Small effect sizes for these outcomes are achieved after 3 to 10, large effects after 16 to 51 sessions. The findings suggest that music therapy is an effective treatment which helps people with psychotic and non-psychotic severe mental disorders to improve global state, symptoms, and functioning. Slight improvements can be seen with a few therapy sessions, but longer courses or more frequent sessions are needed to achieve more substantial benefits.

Effects of group music intervention on depression, anxiety, and relationships in psychiatric patients: a pilot study

OBJECTIVE

To test whether group music therapy is effective for improving depression, anxiety, and relationships in psychiatric patients.

METHODS

Twenty six patients were non-randomly allocated to either a music intervention group or a routine care group. The music intervention group received 60 minutes of music intervention for 15 sessions (1 or 2 times weekly). The outcomes were measured with Beck's Depression Inventory, the State and Trait Anxiety Inventory, and the Relationship Change Scale.

RESULTS

After 15 sessions, the music intervention group showed significant improvements in depression, anxiety, and relationships compared with the control group.

CONCLUSIONS

These findings suggest that music can improve depression, anxiety, and relationships in psychiatric patients. However, we cannot elucidate the nonspecific effects. Furthermore, objective and replicable measures are required from a randomized controlled trial with a larger sample size and an active comparable control.

Preliminary evidence for the integration of music into HIV prevention for severely mentally ill Latinas

BACKGROUND

Individuals with severe mental illness (SMI) may be at increased risk of HIV infection. Prevention programs designed specifically for SMI have relied primarily on principles of cognitive-behavior change theories delivered in a small group format and in venues and services utilized by SMI. Most intervention effects have not been shown to be sustainable over time. We report on our findings relating to the importance of music to Puerto Rican women with SMI and the implications for HIV prevention interventions with this population.

METHODS

We interviewed and shadowed over a 2-year period 53 women of Puerto Rican ethnicity between the ages of 18 and 50, residing in northeastern Ohio, who had been diagnosed with schizophrenia, bipolar disorder, or major depression.

RESULTS

Nearly one-half of the participants listened to music regularly. Some reported that music was essential to their lives. Participants reported that music improved their mental and social well-being by facilitating expression and reflection of their emotions and increasing their energy levels.

DISCUSSION

Music may affect the core negative symptoms and compensate for neuropsychological deficits in women with schizophrenia and related conditions by facilitating the articulation of emotion and allowing individuals to better attend to and potentially incorporate external activities into their lives. The use of music in HIV prevention efforts with SMI Latinas may facilitate their emotional expression and assist them in integrating the educative efforts into their life style choices.

Development of a Music Group Psychotherapy Intervention for the Primary Prevention of Adjustment Difficulties in Korean Adolescent Girls

PROBLEM

Traditionally, adolescent mental health in Korea has not been a prime focus for educators, health workers, and politicians, yet a majority of sampled adolescents report interpersonal sensitivity (Kim, 2003).

METHOD

Thirty-five adolescent girls took part in a six-session school-based music group psychotherapy pilot intervention designed to promote relationships and improve self-control skills.

FINDING

Participants identified several outcome benefits that may serve as protective factors in their continued social and emotional development.

CONCLUSIONS

Music is a medium that promotes interpersonal relatedness among Korean adolescent girls. More research is necessary to identify long-term benefits of preventive music group psychotherapy interventions among the adolescent population.

Music therapy for schizophrenia or schizophrenia-like illnesses

BACKGROUND

Music therapy is a psychotherapeutic method that uses musical interaction as a means of communication and expression. The aim of the therapy is to help people with serious mental illness to develop relationships and to address issues they may not be able to using words alone.

OBJECTIVES

To review the effects of music therapy, or music therapy added to standard care, compared to placebo, standard care or no treatment for people with serious mental illnesses such as schizophrenia.

SEARCH STRATEGY

The Cochrane Schizophrenia Group's Register (July 2002) was searched. This was supplemented by hand searching of music therapy journals, manual searches of reference lists, and contacting relevant authors.

SELECTION CRITERIA

All randomised controlled trials that compared music therapy with standard care or other psychosocial interventions for schizophrenia.

DATA COLLECTION AND ANALYSIS

Studies were reliably selected, quality assessed and data extracted. Data were excluded where more than 30% of participants in any group were lost to follow up. Non-skewed continuous endpoint data from valid scales were synthesised using a standardised mean difference (SMD). If statistical heterogeneity was found, treatment 'dosage' and treatment approach were examined as possible sources of heterogeneity.

MAIN RESULTS

Four studies were included. These examined the effects of music therapy over the short to medium term (1 to 3 months), with treatment 'dosage' varying from 7 to 78 sessions. Music therapy added to standard care was superior to standard care alone for global state (medium term, 1 RCT, n = 72, RR 0.10 CI 0.03 to 0.31, NNT 2 CI 1.2 to 2.2). Continuous data suggested some positive effects on general mental state (1 RCT, n=69, SMD average endpoint PANSS -0.36 CI -0.85 to 0.12; 1 RCT, n=70, SMD average endpoint BPRS -1.25 CI -1.77 to -0.73),on negative symptoms (3 RCTs, n=180, SMD average endpoint SANS -0.86 CI -1.17 to -0.55) and social functioning (1 RCT, n=70, SMD average endpoint SDSI score -0.78 CI -1.27 to -0.28). However these latter effects were inconsistent across studies and depended on the number of music therapy sessions. All results were for the 1-3 month follow up.

AUTHORS' CONCLUSIONS

Music therapy as an addition to standard care helps people with schizophrenia to improve their global state and may also improve mental state and functioning if a sufficient number of music therapy sessions are provided. Further research should address the dose-effect relationship and the long-term effects of music therapy.
