Negative Body Experience in a Clinical Sample of Mental Disorders: Associations With Posttraumatic Stress Disorder, Mood Disorders, and Personality Disorders

While body experience is a key focus of treatment in psychomotor therapy (PMT), research has largely overlooked this important topic. In this study we explored three domains of body experience-body satisfaction, body attitude, and interoceptive awareness-in individuals with mental disorders in a clinical sample receiving PMT. We expected these patients to have a more negative body experience than nonclinical controls, with PTSD, mood disorders, personality disorders, and sex negatively affecting all three domains of body experience. The study involved 235 participants aged 18-59 with various mental disorders that were referred to PMT between 2008 and 2017 at a mental health center in the Netherlands. They completed questionnaires on all three of the body experience domains of interest. One sample t-tests revealed that patients had significantly greater negative body satisfaction and body attitude than nonclinical control samples obtained from the literature, with no significant difference in interoceptive awareness. Regression analyses within the patient sample revealed that female patients and patients with mood disorders or PTSD, displayed more negative body satisfaction than patients with other mental disorders. Additionally, female patients and patients with mood disorders displayed more negative body attitude. Although the total patient group and controls had comparable interoceptive awareness, only PTSD had significantly lower interoceptive awareness. Age and personality disorders did not predict differences on any domain of body experience. This research demonstrates that body experience is disturbed in patients with mental disorders who received PMT, and that there are disorder-specific disturbances on domains of body experience domains.

Early life adversity blunts the subjective and physiological relaxation response in healthy adults

While Early Live Adversity (ELA) is a known risk factor for mental and physical diseases, the investigation into the mechanisms behind this connection is ongoing. In the present study, we investigated whether ELA blunts the relaxation response in healthy adults. Using a within-subjects design, we employed a paced breathing exercise (four seconds inhale, six seconds exhale) and a 360° nature video as relaxation interventions while measuring physiological relaxation using heart rate variability and subjective relaxation using the Relaxation State Questionnaire. A total of 103 participants (63.11% female; agemean = 22.73 ± 3.43 years) completed the Parental Bonding Instrument and the Childhood Trauma Questionnaire to assess ELA retrospectively. For subjective relaxation, a blunted relaxation reaction was associated with lower scores of paternal care and higher scores of paternal overprotection, physical abuse, physical neglect, and emotional abuse. For heart rate variability emotional abuse in interaction with nicotine consumption was related to a blunted relaxation response. This indicates that experiencing ELA negatively affects the relaxation capability in a healthy sample and emphasizes the importance of assessing relaxation at a physiological and subjective level.

Effects of psychotherapy interventions on anxiety and depression in patients with gastrointestinal cancer: A systematic review and network meta-analysis

OBJECTIVE

Various psychological interventions have been demonstrated to be effective at preventing anxiety and depression symptoms in patients with gastrointestinal (GI) cancer. However, it remains unclear which intervention is the best option. This study aimed to evaluate the impact of various psychological interventions on anxiety and depression in symptomatic patients with GI cancer.

METHODS

The PubMed, Cochrane Library, Embase, CNKI, WanFang Data, and VIP databases were systematically searched from inception to June 2023 to identify randomized controlled trials (RCTs). The primary outcomes were anxiety and depression levels. Two reviewers independently selected the studies, extracted the data based on prespecified criteria, and evaluated the risk of bias using the Cochrane Collaboration risk of bias tool. Stata 14.0 was used to conduct network meta-analysis.

RESULTS

Thirty-two RCTs (2453 patients) involving 9 psychological interventions were included. The results of the network meta-analysis showed that cognitive-behavioral therapy (CBT; mean difference [MD] = -4.98, 95% CI (-7.04, -2.93), relaxation therapy (MD = -4.39, 95% CI (-7.90, -0.88), reminiscence therapy (MD = -5.01, 95% CI (-8.20, -1.81)), and narrative nursing (MD = -4.89, 95% CI (-8.54, -1.23)) significantly reduced anxiety levels, and CBT (MD = -2.15, 95% CI (-4.28, -0.02), reminiscence therapy (MD = -7.20, 95% CI (-10.48, -3.91), and narrative nursing (MD = -7.20, 95% CI (-10.48, -3.91)) significantly reduced depression levels in patients with GI cancer compared with conventional nursing care.

CONCLUSION

The findings of this network meta-analysis revealed that CBT, reminiscence therapy and narrative nursing can be actively considered as part of sequential therapy to reduce anxiety and depression levels in patients with GI cancer.

Efficacy of Progressive Muscle Relaxation in Adults for Stress, Anxiety, and Depression: A Systematic Review

Background

The rise in the prevalence of mental health problems among adults worldwide has raised concerns, highlighting the critical need for evidence-based mental health interventions that are accessible, comprehensive, and effective. Previous research suggests that Progressive Muscle Relaxation (PMR) is a promising intervention widely used to reduce mental health problems. Nevertheless, the current literature on the efficacy of PMR among adults globally is fragmented, indicating a potential gap in this research area. Hence, this paper aims to systematically compile the research evidence on the efficacy of PMR in adults for stress, anxiety, and depression.

Methods

The Scopus, Web of Sciences, PubMed, PsycINFO, and Cochrane Central Register of Controlled Trials were searched from the earliest available evidence to 28th March 2023. The PRISMA (Preferred Reporting Items of Systematic Reviews and Meta-analyses) guidelines were followed, and the protocol was registered on the Open Science Framework. Joanna Briggs Institute (JBI) Critical Appraisal Tools were used to assess the quality of the included studies.

Results

A total of forty-six (46) publications from sixteen (16) countries covering more than 3402 adults were included in the review. The results show that PMR are effective in reducing stress, anxiety, and depression in adults. When PMR is combined with other interventions, the combined techniques have also consistently exhibited enhanced efficacy. Moreover, findings also indicate that the efficacy of PMR is heightened when implemented in conjunction with other interventions, surpassing its standalone efficacy.

Funding and Registration

This research was supported/funded by the Ministry of Higher Education (MoHE) under the Fundamental Research Grant Scheme (FRGS) (FRGS/1/2020/SS0/UTM/02/23). The review was registered on Open Science Framework (OSF) on the 7th of March 2023; DOI: https://doi.org/10.17605/OSF.IO/U2HZP.

Improving adherence to a web-based cognitive-behavioural therapy program for social anxiety with group sessions: A randomised control trial

Individuals with social anxiety disorder (SAD) commonly receive non-evidence based, ineffective treatments. Cognitive behaviour therapy (CBT) has been demonstrated to be the gold standard treatment for treating SAD. Scalable web-based CBT programs ensure evidence-based treatment procedures, but low treatment adherence remains problematic. This study aimed to test whether adding group sessions to a fully automated web-based CBT program, Overcome Social Anxiety (OSA), would increase treatment adherence. A total of 69 participants were provided access to a web-based program, and randomly allocated to three conditions: 1) An experimental condition involving an addition of three online group psychoeducation sessions; 2) a placebo condition involving an addition of three online progressive muscle relaxation (PMR) group sessions, or 3) a control condition where participants did not receive group sessions. Adherence was operationalised as number of OSA modules completed. Treatment adherence significantly differed between the conditions. On average, participants assigned to the placebo condition completed significantly more of the program compared to those in the control condition. Further, all conditions produced a significant improvement in BFNE and QOLS. No significant difference in treatment efficacy was found between groups on the SIAS, BFNE or QOLS. The current results indicate PMR can improve treatment adherence for scalable social anxiety interventions.

Stress Management in Elementary School Students: a Pilot Randomised Controlled Trial

Research has shown that stress experiences begin in early stages of life. Stress management techniques have appeared to be beneficial for the development or enhancement of stress coping skills. The aim of this pilot randomised controlled trial was to assess the effect of a 12-week intervention, comprising training in diaphragmatic breathing and progressive muscular relaxation, on elementary school students’ stress levels. Outcomes on the quality of life and behavioural aspects of the students were also assessed. Standardised questionnaires were administered at baseline and after the 12-week intervention program. Fifty-two children aged 10 to 11 years were randomly assigned to intervention (n=24) and control groups (n=28). Children of the intervention group demonstrated lower levels of stress (in all three subscales of lack of well-being, distress, and lack of social support) and improved aspects of quality of life (physical, emotional, and school functioning). No significant differences were observed regarding the examined behavioural dimensions, in the intervention group. Larger randomised controlled trials with follow-up evaluations are needed to ascertain the positive outcomes of such programs on elementary school children.

Effect of progressive muscle relaxation exercise on clinical stress and burnout in student nurse interns

PURPOSE

To determine the effects of progressive muscle relaxation exercise (PMRE) on clinical stress and burnout in student nurse interns.

DESIGN AND METHODS

This is a randomized controlled trial. Interns were divided into control group (CG; n = 78) or experimental group (EG; n = 67) randomly. PMRE was performed by students in the EG. Personal information form, Burnout Measure Short Version (BMS) and Physio-Psycho-Social Response Scale (PPSRS) for nursing students were administered to both groups in the first and last meeting.

FINDINGS

There was a significant difference in posttest scores between groups; EG posttest scores on the BMS, on the PPSRS, and subscales were lower than those of the CG.

PRACTICE IMPLICATIONS

PMRE training ameliorates burnout and PPSRs to stress during clinical practice in nursing students.

Efficacy of Facial Exercises in Facial Expression Categorization in Schizophrenia

Embodied cognition theories suggest that observation of facial expression induces the same pattern of muscle activation, and that this contributes to emotion recognition. Consequently, the inability to form facial expressions would affect emotional understanding. Patients with schizophrenia show a reduced ability to express and perceive facial emotions. We assumed that a physical training specifically developed to mobilize facial muscles could improve the ability to perform facial movements, and, consequently, spontaneous mimicry and facial expression recognition. Twenty-four inpatient participants with schizophrenia were randomly assigned to the experimental and control group. At the beginning and at the end of the study, both groups were submitted to a facial expression categorization test and their data compared. The experimental group underwent a training period during which the lip muscles, and the muscles around the eyes were mobilized through the execution of transitive actions. Participants were trained three times a week for five weeks. Results showed a positive impact of the physical training in the recognition of others’ facial emotions, specifically for the responses of “fear”, the emotion for which the recognition deficit in the test is most severe. This evidence suggests that a specific deficit of the sensorimotor system may result in a specific cognitive deficit.

In- and outpatient lifestyle interventions on diet and exercise and their effect on physical and psychological health: a systematic review and meta-analysis of randomised controlled trials in patients with schizophrenia spectrum disorders and first episode of psychosis

Patients with non-affective psychosis often lead unhealthy lifestyles. We performed a systematic review and meta-analysis on non-pharmacological RCTs for improvement of diet and physical activity in non-affective psychosis patients, including first-episode psychosis. A variety of outcomes was analysed, including metabolic, psychopathology, cognitive, functional and quality of life outcomes. Fifty-nine studies were included. An improvement in anthropometric measurements (BMI, weight, waist circumference) was observed post-intervention, persisting after follow-up. Post-intervention benefit was found also for psychotic symptoms severity (also persisting after follow-up), many cognitive domains and physical and global functioning and quality of life. Conversely, no effect was observed in relation to most blood metabolites, blood pressure and non-psychotic psychopathology and spontaneous physical activity. Improvement was generally larger for interventions including exercise, especially moderate/vigorous aerobic exercise, but follow-up maintenance was greater for psychotherapy interventions. Sensitivity analyses limited to chronic stages of psychosis and low risk of bias studies produced comparable results. Further studies are needed to design optimized interventions in this vulnerable population.

Virtual Reality Relaxation for Patients With a Psychiatric Disorder: Crossover Randomized Controlled Trial

Background

Virtual reality (VR) relaxation is a promising mental health intervention that may be an effective tool for stress reduction but has hardly been tested in clinical trials with psychiatric patients. We developed an easy-to-use VR self-management relaxation tool (VRelax) with immersive 360° nature videos and interactive animated elements.

Objective

To investigate the immediate effects of VR relaxation on negative and positive affective states and short-term effects on perceived stress and symptoms in patients with a psychiatric disorder, compared to standard relaxation exercises.

Methods

A randomized crossover trial was conducted in 50 patients receiving ambulatory treatment for anxiety, psychotic, depressive, or bipolar disorder. Participants were randomly assigned to start with VRelax or standard relaxation and used both interventions for 10 days at home. They completed 8 visual analog scales of momentary negative and positive affective states before and after each session. Global perceived stress and psychiatric symptoms were measured before and after both intervention periods. Treatment effects were analyzed with multilevel mixed model regression analyses and 2-way analysis of variance.

Results

Both VRelax and standard relaxation exercises led to a statistically significant immediate improvement of all negative and positive affective states. Compared to standard relaxation, VRelax resulted in a significantly greater reduction of total negative affective state (change 16.2% versus 21.2%; t₁₆₈₄=−2.02, 95% CI −18.70 to −0.28; P=.04). Specifically, VRelax had a stronger beneficial effect on momentary anxiety (t₁₆₈₄=−3.24, 95% CI −6.86 to −1.69), sadness (t₁₆₈₄=−2.32, 95% CI −6.51 to −0.55), and cheerfulness (t₁₆₈₄=2.35, 95% CI 0.51 to 5.75). There were no significant differences between short-term effects of the two treatments on global perceived stress and symptoms.

Conclusions

If the results of this trial are replicated and extended, VRelax may provide a much-needed, effective, easy-to-use self-management relaxation intervention to enhance psychiatric treatments.

Relaxation techniques for depressive disorders in adults: a systematic review and meta-analysis of randomised controlled trials

Objectives: The aim of this study was to identify, evaluate, and synthesise existing randomised controlled trials (RCTs) that examined the effect of relaxation techniques in the treatment of patients with depressive disorders.Methods: A systematic review of the literature was performed based on the Preferred Reporting Items for Systematic Reviews and Meta-analysis guidelines.Results: Nine studies were finally included in this meta-analysis. It was found that relaxation techniques might effectively reduce depressive symptoms among adults with depression (standardised mean difference (SMD) -0.42, 95% CI -0.72 to -0.11, p  =  0.008).Conclusions: Relaxation techniques are cost-effective, safe, and low-risk techniques that can be easily taught and used. Consequently, they have several benefits if practised regularly daily for more than an 8-week period.KEY POINTS/HIGHLIGHTSThe implication of this study for practice is that these relaxation techniques, cost-effective, safe, and low-risk techniques that can be easily taught and used.Consequently, practitioners will access benefits if practised regularly daily for more than an 8-week period.The relaxation technique is not complex, does not need any special device or place, does not need any change in lifestyle and is easily learned.

The effect of progressive muscle relaxation on the postpartum depression risk and general comfort levels in primiparas

In the postpartum period, mode of delivery, planned pregnancy, rapid changes in estrogen and progesterone hormone concentrations, quality of care, and environmental conditions affect the postpartum depression and comfort of the women. This study was conducted to evaluate the effect of progressive muscle relaxation (PMR) on the postpartum depression risk and general comfort levels in primiparas. A quasi-experimental design was used with pretest, post-test, and control group. The intervention and control groups consisted of 35 women each. PMR was applied to intervention group for 8 weeks. There was a statistically significant difference between Edinburgh Postnatal Depression Scale pretest and third follow-up scores of the intervention group (p < .05). There was a statistically significant difference between the intervention and control groups in the mean General Comfort Questionnaire scores at the first, second, and third follow-ups (p < .05). PMR may be effective on decreasing the postpartum depression risk and increasing general comfort. PMR could be administered through home visits to help women in postpartum period cope with their mental health problems after discharge.

Progressive muscle relaxation for patients with chronic schizophrenia: A randomized controlled study

PURPOSE

To evaluate progressive muscle relaxation (PMR) as an intervention for anxiety, psychotic symptoms, and quality of life (QOL) in patients with chronic schizophrenia.

DESIGN AND METHODS

Eighty patients were recruited from a Taiwanese psychiatry ward. The intervention group received group PMR; control group received treatment-as-usual.

RESULTS

The results indicated that PMR might have a short-term effect on reducing anxiety, improving psychotic syndromes, and QOL among patients with chronic schizophrenia; however, the effectiveness at the 3-month follow-up was not evident.

PRACTICE IMPLICATIONS

Both the psychiatric patients and the health institutions may be able to list PMR as a clinical routine care, and then become a mental health practice strategy for mental patients to improve the quality of mental care.

IMPLICATIONS FOR NURSING PRACTICE

Our studies suggest that prevention of severe mental illness among patients with schizophrenia requires PMR interventions. PMR had an immediate effect, and it is possible that a shorter intervention period using this approach would also be successful.

Promoting mental health and wellbeing in schools: examining Mindfulness, Relaxation and Strategies for Safety and Wellbeing in English primary and secondary schools: study protocol for a multi-school, cluster randomised controlled trial (INSPIRE)

BACKGROUND

There are increasing rates of internalising difficulties, particularly anxiety and depression, being reported in children and young people in England. School-based, universal prevention programmes are thought to be one way of helping tackle such difficulties. This protocol describes a four-arm cluster randomised controlled trial, investigating the effectiveness of three different interventions when compared to usual provision, in English primary and secondary pupils. The primary outcome for Mindfulness and Relaxation interventions is a measure of internalising difficulties, while Strategies for Safety and Wellbeing will be examined in relation to intended help-seeking. In addition to the effectiveness analysis, a process and implementation evaluation and a cost-effectiveness evaluation will be undertaken.

METHODS AND ANALYSIS

Overall, 160 primary schools and 64 secondary schools will be recruited across England. This corresponds to 17,600 participants. Measures will be collected online at baseline, 3-6 months later, and 9-12 months after the commencement of the intervention. An economic evaluation will assess the cost-effectiveness of the interventions. Moreover, a process and implementation evaluation (including a qualitative research component) will explore several aspects of implementation (fidelity, quality, dosage, reach, participant responsiveness, adaptations), social validity (acceptability, appropriateness and feasibility), and their moderating effects on the outcomes of interest, and perceived impact.

DISCUSSION

This trial aims to address important questions about whether schools' practices around the promotion of mental wellbeing and the prevention of mental health problems can: (1) be formalised into feasible and effective models of school-based support and (2) whether these practices and their effects can be sustained over time. Given the focus of these interventions on mirroring popular practice in schools and on prioritising approaches that present low-burden, high-acceptability to schools, if proved effective, and cost-effective, the findings will indicate models that are not only empirically tested but also offer high potential for widespread use and, therefore, potentially widespread benefits beyond the life of the trial.

Schizophrenia and Progressive Muscle Relaxation - A systematic review of effectiveness

Objective

We perform a systematically search, appraise and synthesize of the best available evidence on the effectiveness of Progressive Muscle Relaxation (PMR) in the adults with schizophrenia, in any setting, regarding anxiety, personal and social functioning, cognition, and well-being.

Method

Major databases were searched to find both published and unpublished studies from inception until April 2017, using Schizophren* AND Relax* as keywords, and studies published in Portuguese, English, Spanish, Italian, French were considered for inclusion in this review. Methodological quality was assessed by two independent reviewers using the Critical Appraisal Checklist for Randomized Controlled Trials from the Joanna Briggs Institute.

Results

From a total of 1172 studies, five studies, involving 216 adults with schizophrenia, met the inclusion criteria for this systematic review after assessment of their methodological quality. These studies reported benefits in experimental group participants after PMR intervention on anxiety (assessed with State anxiety inventory, Beck Anxiety Inventory and Spielberger Trait Anxiety Inventory), well-being (assessed with Subjective Exercise Experiences Scale) and personal and social functioning (assessed with Sheehan Disability Scale and Therapist Rating Scale).

Conclusions

Evidence suggests that PMR was effective in adults diagnosed with schizophrenia, except in one study where was only effective when combined with education. Thus, PMR may be useful to decrease state anxiety, improve well-being and social functioning in adults diagnosed with schizophrenia. However, due to the diversity of clinical intervention designs of PMR (different number and length of sessions) and outcome assessment scales, no strong evidence was found in this systematic review.

Efficacy of metacognitive training for patients with borderline personality disorder: Preliminary results

'Metacognitive training for borderline personality disorder' (B-MCT) represents a complementary group intervention. It aims at raising awareness for cognitive biases that may play an important role in the development and maintenance of borderline symptomatology. For the present study, we evaluated the effectiveness of this new approach against a control condition. Seventy-four inpatients with borderline personality disorder (BPD) were randomly assigned to metacognitive training for BPD or progressive muscle relaxation training as an add-on intervention to treatment as usual. Severity of symptomatology was assessed at baseline, four weeks after beginning and six months after completion of the intervention. The per-protocol and intention-to-treat analyses revealed that patients in the metacognitive training group showed significantly greater reductions on the primary outcome (Borderline Symptom List-23) after six months. Progressive muscle relaxation was superior in alleviating depressive symptoms (secondary outcome: Beck Depression Inventory) at the long-term follow-up. Findings provide preliminary evidence that metacognitive training for BPD yields surplus effects to standard treatment.

Self-Active Relaxation Therapy (SART) and Self-Regulation: A Comprehensive Review and Comparison of the Japanese Body Movement Approach

Relaxation programs are known for their versatility, cost-effectiveness, and ability to help people obtain skills to regulate their mental states and promote and maintain health. Self-Active Relaxation Therapy (SART) is a body-oriented approach to psychological rehabilitation that grew out of the suite of movement tasks developed in the Japanese psychotherapy known as Dohsa-hou, or the body movement method. The program for SART is designed to stretch, twist, and release areas of the upper, lower, and whole body through a set of movements which are guided by the practitioner and performed "self-actively" by the client to empower them to learn to recognize points of tension in the body and act on their own to achieve a relaxed state. Numerous studies have showed that SART is associated with reduced negative mood states and enhanced body awareness. A short version of SART has been investigated as a psychological support salon activity for the elderly, mothers raising children, special needs students, and children adapting to school. The full program has also been applied in clinical settings to address or supplement treatments for psychological and developmental conditions, and longitudinally employed in community contexts to assist residents facing long-term disaster recovery circumstances in Japan. This paper reviews the research and applications of SART as a bodymind approach by critically examining evidence and research gaps for future studies, comparing it with techniques established in the literature, and positing a self-regulatory framework for SART as a tool to become aware of bodily states, regulate mood, and manage stress through the deliberate practice of relaxation.

Progressive muscle relaxation as a supportive intervention for cancer patients undergoing chemotherapy: A systematic review

BACKGROUND

Many cancer patients use a wide variety of techniques to improve their physical and mental well-being, including relaxation therapy and, specifically, Progressive Muscle Relaxation (PMR). However, there is no strong evidence that supports the efficacy of this technique.

OBJECTIVE

Our aim was to review the evidence regarding the use of PMR as a supportive intervention for cancer patients undergoing chemotherapeutic treatment.

METHOD

Six databases were electronically searched: AMED, the Cochrane Library, MEDLINE, PsychINFO, Scopus, and the Web of Science. After removing duplicates, 700 publications were screened and 57 identified as potentially relevant. The flow of information from record identification to study inclusion was conducted in accordance with the PRISMA statement. Original articles published in peer-reviewed journals that studied the use of PMR as an intervention, were randomized or included a matched control group, and that included patients receiving chemotherapy were included. Studies that combined PMR with other interventions were excluded. The methodological quality of included trials was assessed using the Jadad Scale and the CONSORT guidelines.

RESULTS

A total of 5 of the 57 papers fulfilled the preset criteria and were included in our systematic review. Our findings indicate that PMR might improve comfort and reduce the anxiety levels and side effects caused by chemotherapy, with the exception of vomiting. Nonetheless, the quality of all the included studies was extremely low.

SIGNIFICANCE OF RESULTS

There is evidence that PMR might have a few benefits for patients undergoing chemotherapy. Still, the small number of studies included and their poor quality limit the significance of our results. Despite the fact that pharmaceutical approaches for controlling side effects might be reaching their full potential and that there might be further usefulness for such integrative treatments as PMR, the need to run more high-quality trials testing the efficacy of this technique is warranted before suggesting its adoption as part of standard cancer care.

Environmental Social Stress, Paranoia and Psychosis Liability: A Virtual Reality Study

The impact of social environments on mental states is difficult to assess, limiting the understanding of which aspects of the social environment contribute to the onset of psychotic symptoms and how individual characteristics moderate this outcome. This study aimed to test sensitivity to environmental social stress as a mechanism of psychosis using Virtual Reality (VR) experiments. Fifty-five patients with recent onset psychotic disorder, 20 patients at ultra high risk for psychosis, 42 siblings of patients with psychosis, and 53 controls walked 5 times in a virtual bar with different levels of environmental social stress. Virtual social stressors were population density, ethnic density and hostility. Paranoia about virtual humans and subjective distress in response to virtual social stress exposures were measured with State Social Paranoia Scale (SSPS) and self-rated momentary subjective distress (SUD), respectively. Pre-existing (subclinical) symptoms were assessed with the Community Assessment of Psychic Experiences (CAPE), Green Paranoid Thoughts Scale (GPTS) and the Social Interaction Anxiety Scale (SIAS). Paranoia and subjective distress increased with degree of social stress in the environment. Psychosis liability and pre-existing symptoms, in particular negative affect, positively impacted the level of paranoia and distress in response to social stress. These results provide experimental evidence that heightened sensitivity to environmental social stress may play an important role in the onset and course of psychosis.

A randomized-controlled trial of heart rate variability biofeedback for psychotic symptoms

Arousal and the way it is coped with are relevant to the emergence of psychotic symptoms. Heart rate variability (HRV) stems from autonomic responses to environmental demands such as stress and is an index of physiological arousal, adaptability, and homeostatic reflexes forming autonomic balance. A randomized-controlled between-subjects trial that compared HRV-biofeedback (BF) to an active relaxation and to a waiting control condition was conducted in a sample with attenuated subclinical psychotic symptoms (N = 84). A 20-min intervention was preceded and followed by repeated assessments of stress responses. Change scores of the post-stress periods were analyzed using ANOVAs for HRV, subjective stress, perceived control, and state paranoia. As expected, BF participants showed greater improvements in perceived control than waiting controls (p = 0.006). However, no group differences occurred in HRV, paranoid symptoms or subjective stress. In exploratory analyses in a subset of participants who were breathing per protocol, the expected effects were found for total HRV and state paranoia. Thus, this trial of HRV-BF for people with attenuated psychotic symptoms indicates that the intervention may hold potential if conducted per protocol. To reach this, longer training might be inevitable. Future studies are needed to further elucidate efficacy and applicability of HRV-BF in clinical samples.

Effects of relaxation interventions on depression and anxiety among older adults: a systematic review

OBJECTIVES

This systematic review examined empirical evidence of the effects of relaxation interventions on anxiety and depression among older adults.

METHOD

A comprehensive literature search identified studies that satisfied the pre-set inclusion and exclusion criteria. We focused on 15 published and non-published studies - 12 randomised controlled trials and three non-randomised controlled trials - undertaken in the past 20 years (1994-2014). Three reviewers selected studies, extracted data, and appraised the methodological quality. We then computed Hedges' effect sizes and used these to represent the effects of intervention.

RESULTS

Our findings suggested that older adults who received relaxation interventions experienced greater reductions in depression and anxiety than controls in most studies. Progressive muscle relaxation training, music intervention, and yoga had the strongest intervention effects on depression. Music intervention, yoga, and combined relaxation training most effectively reduced anxiety symptoms among older adults. Furthermore, the impact of some relaxation interventions remained in effect for between 14 and 24 weeks after the interventions.

CONCLUSION

This systematic review supported the positive effects of relaxation interventions on depression and anxiety among older adults. Health care providers may integrate relaxation interventions into standard care for older adults in community and hospital settings, taking into consideration the participant's preference and health care policy.

A systematic review of the benefits of physical therapy within a multidisciplinary care approach for people with schizophrenia: An update

This systematic review summarizes the most recent evidence from randomized controlled trials (RCTs) considering the effectiveness of physical therapy interventions (aerobic exercises, strength exercises, relaxation training, basic body awareness exercises, or a combination of these) within the multidisciplinary management of schizophrenia. Two authors searched PubMed, PsycINFO, EMBASE, Web of Science, Physiotherapy Evidence Database (PEDro), and the Cochrane Library considering RCTs published from July 1, 2011-October 1, 2014. Thirteen RCTs representing 549 participants met the inclusion criteria. Overall, the results demonstrate that aerobic exercise significantly reduces psychiatric symptoms, potentially improves mental and physical quality of life and reduces metabolic risk and weight. Specifically, yoga reduces psychiatric symptoms, whilst Tai-chi and progressive muscle relaxation may also have benefits to patients. Two RCTs reported on adverse events. No adverse event was observed supporting the notion that physical therapy is safe in people with schizophrenia. There was considerable heterogeneity in the design, implementation and outcomes in the included studies precluding a meaningful meta-analysis. In general, the quality of physical therapy RCTS is improving and current research demonstrates that physical therapy approaches are valuable interventions and can help improve the psychiatric, physical and quality of life of people with schizophrenia.

Anxiety and Anger Symptoms in Hwabyung Patients Improved More following 4 Weeks of the Emotional Freedom Technique Program Compared to the Progressive Muscle Relaxation Program: A Randomized Controlled Trial

Background. The Emotional Freedom Technique (EFT) is a meridian-based psychological therapy. The present clinical trial investigates the effectiveness of EFT as a new treatment option for Hwabyung (HB) patients experiencing anger and compares the efficacy to the Progressive Muscle Relaxation (PMR), the conventional meditation technique. Methods. The EFT and progressive muscle relaxation (PMR) methods were performed on 27 HB patients, and their capacities to alleviate anxiety, anger, and emotional status were compared. After a 4-week program, a survey was conducted; patients then completed a self-training program for 4 weeks, followed by a second survey. Results. During the initial 4 weeks, the EFT group experienced a significant decrease in the HB symptom scale, anger state, and paranoia ideation (p < 0.05). Over the entire 9-week interval, there were significant decreases in the HB symptom scale, anxiety state, anger state, anger trait, somatization, anxiety, hostility, and so on in EFT group (p < 0.05). Conclusion. The EFT group showed improved psychological symptoms and physical symptoms greater than those observed in the PMR group. EFT more effectively alleviated HB symptoms compared to PMR. EFT group showed better maintenance during self-training, suggesting good model of self-control treatment in HB patients.

How should we manage anxiety in patients with schizophrenia?

OBJECTIVE

We aim to provide a selective clinically focused review of the epidemiology, aetiology and management of comorbid anxiety in people with schizophrenia.

METHOD

The following databases were reviewed: PubMed, Medline and Embase.

RESULTS

Anxiety is highly prevalent throughout course of schizophrenia, but is often not identified or its clinical significance is under-appreciated. Also, there is a paucity of rigorous data to support specific treatment guidelines for people with schizophrenia and concurrent anxiety disorders. Psychological treatments such as cognitive behavioural therapy appear effective if targeted carefully, and preliminary data suggest that mindfulness approaches and progressive muscle relaxation may be beneficial. Pharmacological interventions need to be tailored to the individual and target specific symptom sets. There is a growing evidence base about the neurobiology of schizophrenia and concurrent anxiety symptoms or disorders which will hopefully enhance treatment options.

CONCLUSIONS

Further research is required to guide treatment guidelines for anxiety in people with schizophrenia.

S3 guideline on psychosocial therapies in severe mental illness: evidence and recommendations

The burden of severe and persistent mental illness is high. Beside somatic treatment and psychotherapeutic interventions, treatment options for patients with severe mental illness also include psychosocial interventions. This paper summarizes the results of a number of systematic literature searches on psychosocial interventions for people with severe mental illness. Based on this evidence appraisal, recommendations for the treatment of people with severe mental illness were formulated and published in the evidence-based guideline series of the German Society for Psychiatry, Psychotherapy and Neurology (DGPPN) as an evidence-based consensus guideline ("S3 guideline"). Recommendations were strongly based on study results, but used consensus processes to consider external validity and transferability of the recommended practices to the German mental healthcare system. A distinction is made between system-level interventions (multidisciplinary team-based psychiatric community care, case management, vocational rehabilitation and participation in work life and residential care interventions) and single psychosocial interventions (psychoeducation, social skills training, arts therapies, occupational therapy and exercise therapy). There is good evidence for the efficacy of the majority of psychosocial interventions in the target group. The best available evidence exists for multidisciplinary team-based psychiatric community care, family psychoeducation, social skills training and supported employment. The present guideline offers an important opportunity to further improve health services for people with severe mental illness in Germany.

A conceptual framework for improving well-being in people with a diagnosis of psychosis

Background. Well-being is important for people with severe mental illness, such as psychosis. So far, no clear concept of well-being exists for this client group. A recent systematic review and narrative synthesis developed a static framework of well-being components. The present study aims to validate the static framework and to illuminate the processes by which well-being is experienced by people with psychosis. Methods. Semi-structured interviews were conducted with 23 service users with psychosis exploring their experience of well-being. Thematic analysis was used to analyse the data employing techniques taken from grounded theory to enhance the rigour of the analysis. Respondent validation was undertaken with 13 of the 23 participants. Results. Three superordinate categories of well-being were identified: current sense of self; transition to enhanced sense of self and enhanced sense of self. In the dynamic process of improving well-being the current sense of self undergoes a transition to an enhanced sense of self. The four factors influencing the transition are consistent with the static framework of well-being, hence validating the static framework. In addition, we identified three determinants of current sense of self and seven indicators of enhanced sense of self, which represent the achievement of improved well-being. Conclusions. This study provides an empirically defensible framework for understanding well-being in terms of determinants, influences and indicators. The influences are targets for interventions to improve well-being, and the indicators are outcome domains to assess the effectiveness of services in supporting well-being.

The effects of physical exercise in schizophrenia and affective disorders

Affective and non-affective psychoses are severe and frequent psychiatric disorders. Amongst others, they not only have a profound impact on affected individuals through their symptomatology, but also regarding cognition, brain structure and function. Cognitive impairment influences patients' quality of life as well as their ability to work and being employed. While exercise therapy has been implemented in the treatment of psychiatric conditions since the days of Kraepelin and Bleuler, the underlying mechanisms have never been systematically studied. Since the early 1990s, studies emerged examining the effect of physical exercise in animal models, revealing stimulation of neurogenesis, synaptogenesis and neurotransmission. Based on that body of work, clinical studies have been carried out in both healthy humans and in patient populations. These studies differ with regard to homogenous study samples, sample size, type and duration of exercise, outcome variables and measurement techniques. Based on their review, we draw conclusions regarding recommendations for future research strategies showing that modern therapeutic approaches should include physical exercise as part of a multimodal intervention programme to improve psychopathology and cognitive symptoms in schizophrenia and affective disorders.
