The Effect of Breathing and Relaxation Exercises Training on Psychological Well-Being and Sleep Quality in Individuals Diagnosed With Schizophrenia: A Randomized Controlled Study

This study was conducted to determine the effect of breathing and relaxation exercises training on psychological well-being and sleep quality in individuals diagnosed with schizophrenia. This study was conducted at a community mental health center between October 2022 and April 2023 as a randomized controlled study with a pretest-posttest control group. The study's participants were 64 individuals diagnosed with schizophrenia (31 in the experimental group and 33 in the control group). The Descriptive Characteristics Form, the Psychological Well-being Scale, and the Pittsburg Sleep Quality Index were used to collect data. The individuals in the experimental group underwent 6 sessions of breathing and relaxation exercises training in the form of group training, and no training was applied to the individuals in the control group. It was determined that the individuals in the experimental group had an increase in the total mean score of psychological well-being and a decrease in the total mean score of sleep quality after breathing and relaxation exercise training. In addition, a statistically significant difference was found between the posttest psychological well-being and sleep quality total mean scores of the experimental and control groups ( P < .05). It can be said that breathing and relaxation exercises training can be used as an effective intervention to increase the psychological well-being and sleep quality of individuals diagnosed with schizophrenia and can be used in addition to pharmacological treatment.

We like to move it - patients with schizophrenia spectrum disorders are impaired in estimating their physical fitness levels and benefit from individualized exercise

BACKGROUND

People with schizophrenia spectrum disorders (SSD) engage less in physical activity than healthy individuals. The impact of subjectively assessed physical fitness levels on motivation for sports engagement and its relation to objective fitness parameters in SSD is unclear.

METHODS

25 patients with SSD (P-SSD) and 24 healthy controls (H-CON) participated in a randomized controlled study. Individual anaerobic thresholds (AT) were determined by an incremental exercise test and on separate days, aerobic exercise (cycling at 80% of workload at AT) and non-exercise control (sitting on an ergometer without cycling) sessions were performed. Demographic, clinical and objective physical fitness data (i.e., weekly physical activity, workload at AT, heart rate) were collected. Subjective physical fitness parameters were assessed before and after exercise and control sessions.

RESULTS

Weekly physical activity in P-SSD was lower than in H-CON (p < 0.05) attributed to reduced engagement in sport activities (p < 0.001). Workload and percentage of predicted maximal heart rate at AT were also reduced in P-SSD compared to H-CON (both p < 0.05). Although objective and subjective physical fitness parameters were related in H-CON (p < 0.01), this relationship was absent in P-SSD. However, during exercise sessions subjective physical fitness ratings increased to a stronger extent in P-SSD than H-CON (p < 0.05).

CONCLUSION

The missing relationship between subjective and objective physical fitness parameters in people with SSD may represent a barrier for stronger engagement in physical activity. Accordingly, supervised exercise interventions with individually adjusted workload intensity may support realistic subjective fitness estimations and enhance motivation for sports activity in individuals with SSD.

The Healing Elements of an Eclectic Life Skills Programme: Clients' Perspectives

Introduction: The article reports the healing elements of an eclectic life skills programme (ELSP) from the perspective of group members. An ELSP utilising open groups was developed to manage clients with mixed diagnostic profiles and different stages of recovery simultaneously. The aim was to explore the healing elements of an ELSP. Methods: Maximum variation purposive sampling was used to select six participants for the phenomenological inquiry. Data collection is comprised of observations, semistructured interviews, and reflective journals. Data analysis comprised an inductive thematic analysis. Consumer Involvement: Participants all attended groups offered within the ELSP. They participated in two semistructured interviews: the first interview in the week following admission and the second just before discharge. In addition, they documented their experiences in reflective journals for the duration of their participation. Findings: The analogy of a kaleidoscope portrayed the four themes; three pertained to structural dynamics, namely, programme mirror, facilitator mirror, and mirror of other group members. The fourth theme, namely, the magical pattern, pertained to personal sense-making by individual group members. Conclusions: The dynamic interplay of healing factors, captured in the themes, facilitated healing. Self-reflection was integral to the creation of a bespoke, facilitated self-learning process with direct application in group members' own lives.

Benson relaxation technique to address sleep quality and aggression among patients with bipolar type I disorder: A randomized clinical trial study

Purpose

The present research was conducted to assess the effect of the Benson relaxation technique on sleep quality and aggression among patients with bipolar type I disorder.

Methods

This study was conducted using a randomized clinical trial design with the participation of 60 patients with bipolar type I disorder (30 participants in each group) in Mashhad, Iran (IRCT20220108053659N1). The intervention group received the Benson relaxation technique for 21 days in a row, twice a day (in the morning and evening), under the supervision of an expert psychiatric nurse (On the first day, instruction was given on implementing BRT. In the subsequent days of the intervention, the nurse stayed by the patient's bedside for the entire relaxation process). Aggression and sleep quality were assessed using the Buss-Perry Aggression Questionnaire and Pittsburgh Sleep Quality Index, respectively, before and one week after the completion of the intervention. Data were analyzed using descriptive and inferential statistics (Chi-squared, Fisher's exact test, independent sample t-test, and analysis of covariance).

Results

The participants in the present study were individuals of both genders aged 18 and above. Based on the results, both groups were homogeneous regarding demographic characteristics. Prior to the intervention, the two groups of control and intervention were not significantly different from each other in terms of sleep quality (p = 0.870) and aggression (p = 0.961). After the intervention, in an intergroup comparison, a significant difference was observed between the two groups in terms of the mean difference of aggression (p < 0.001) and sleep quality scores (p < 0.001).

Conclusion

Despite the favorable effect of this intervention, it is necessary to conduct more studies considering the broader aspects of interventions and related variables before including these interventions in the care plan of patients with bipolar type I disorder.

A Mobile Health App (ChillTime) Promoting Emotion Regulation in Dual Disorders: Acceptability and Feasibility Pilot Study

BACKGROUND

A growing number of studies highlight the importance of emotion regulation in the treatment and recovery of individuals with psychosis and concomitant disorders such as substance use disorder (SUD), for whom access to integrated dual-disorder treatments is particularly difficult. In this context, dedicated smartphone apps may be useful tools to provide immediate support to individuals in need. However, few studies to date have focused on the development and assessment of apps aimed at promoting emotional regulation for people with psychosis.

OBJECTIVE

The aim of this study was to evaluate the feasibility, acceptability, and potential clinical impact of a dedicated app (ChillTime) for individuals with psychotic disorders and concurrent SUD. The app design process followed recommendations for reducing cognitive effort on a mobile app. A total of 20 coping strategies regrouped in four categories (behavioral, emotional, cognitive, spiritual) were included in the app.

METHODS

This open pilot study followed a pre-post design. After the initial assessment, researchers asked participants to use the app as part of their treatment over a 30-day period. Feasibility was determined by the frequency of use of the app and measured using the number of completed strategies. Acceptability was determined by measuring ease of use, ease of learning, satisfaction, and perceived utility at the end of the 30-day study period based on responses to satisfaction questionnaires. Clinical scales measuring emotion regulation, substance use (ie, type of substance, amount taken, and frequency of use), and various psychiatric symptoms were administered at the beginning and end of the 30-day period.

RESULTS

A total of 13 participants were recruited from two first-episode psychosis clinics in Montreal, Quebec, Canada. All participants were symptomatically stable, were between 18 and 35 years of age (mostly men; 70% of the sample), and had a schizophrenia spectrum disorder with a comorbid substance use diagnosis. A total of 11 participants completed the study (attrition<20%). Approximately half of the participants used the tool at least 33% of the days (11-21 days). Cognitive and emotion-focused techniques were rated the highest in terms of usefulness and were the most frequently used. The majority of participants gave positive answers about the ease of use and the ease of learning the tool. A nonsignificant association of ChillTime use with negative symptoms and drug use was observed. No other statistically significant changes were observed.

CONCLUSIONS

The ChillTime app showed good feasibility (approximately half of the participants used the tool at least 33% of the days) and acceptability among people with schizophrenia spectrum disorder and SUD. Trends suggesting a potential impact on certain clinical outcomes will need to be replicated in larger-sample studies before any conclusion can be drawn.

The Impact of Health Promotion Activities on the Physiological, Psychological, and Social Functions of Inpatients With Chronic Mental Illness

OBJECTIVE

To explore the impact of the participation of patients with chronic mental illness in health promotion activities on their physical, psychological, and social functions.

METHODS

This study included inpatient with chronic mental illness from a hospital in Eastern Taiwan. According to the experimental research design, the selected subjects were randomly divided into a health promotion group and a control group, with 60 people in each group. The health promotion team conducts health promotion activities twice a week, each for approximately 50 minutes, over the course of eight weeks (16 times in total). The measurement instrument adopts the Adult Mental Health Scale (AMHS) scale. Five experts and scholars in related fields are invited to conduct expert validity.

RESULTS

Using independent sample t-tests to analyze the changes in the two groups after 8 weeks, the physical, psychological and social problems of the health promotion group were significantly improved compared with the control group.

CONCLUSION

Health promotion activities can alleviate the physical illness, anxiety, irritability, depression, and social distress of chronic hospitalized mental patients, and can also increase their positive and optimistic mood. It can provide chronic mental health care institutions to plan patients' physical activities or exercises.

Effect of Benson and progressive muscle relaxation techniques on sleep quality after coronary artery bypass graft: A randomized controlled trial

OBJECTIVE

This study aimed to investigate the effect of Benson relaxation (BR) and progressive muscle relaxation (PMR) techniques on the sleep quality of patients undergoing coronary artery bypass graft (CABG) surgery.

METHOD

This study was a three-arm, parallel, randomized controlled trial. 120 patients who underwent CABG surgery at two academic hospitals in an urban area of Iran were randomly allocated into three groups (40 per group): the BR, PMR, and control groups. Patients in the BR and the PMR groups performed relevant exercises twice a day for four weeks. Sleep quality was measured before and immediately after the intervention using Pittsburgh Sleep Quality Index.

RESULTS

Within-group comparison in the BR (t = 3.51, p = 0.001) and the PMR (t = 4.58, p < 0.001) group showed that the overall sleep quality showed a significant improvement after the intervention when compared to baseline. The between-group comparison showed that both the BR and PMR groups showed significant improvements in subjective sleep quality (F = 3.75, p = 0.02), habitual sleep efficiency (F = 4.81, p = 0.01), and overall sleep quality (F = 5.53, p = 005) when compared to the control group after the intervention. However, no statistically significant differences were identified among the three study groups in terms of sleep latency, sleep duration, sleep disturbances, sleeping medication, and daytime dysfunction after the intervention (p > 0.05).

CONCLUSION

The study showed that a four-week program of both PMR and BR can be effective in the overall improvement of sleep quality in patients following CABG. Further research is required to replicate the findings of the present study.

Effect of progressive muscle relaxation on adaptation to old age and quality of life among older people in a nursing home: a randomized controlled trial

BACKGROUND

Changes occurring in the aging process, the presence of decline in physical and cognitive functions, and the limitations of participation in activities affect adaptation to old age and the quality of life. This study aimed to examine the effect of progressive muscle relaxation (PMR) exercises on adaptation to old age and the quality of life of older people.

METHODS

A randomized controlled trial design was used. The sample consisted of 45 older residents (21 intervention subjects, 24 controls) from a nursing home in a city of Turkey. The intervention group received progressive muscle-relaxation sessions twice weekly for 8 weeks, while the control group received routine care. All PMR exercises were led by the researcher. All participants were evaluated at baseline and after 8 weeks using the Assessment Scale of Adaptation Difficulty for the Elderly and the Nottingham Health Profile.

RESULTS

As a result of PMR exercises performed for 8 weeks, the Assessment Scale of Adaptation Difficulty for the Elderly and Nottingham Health Profile total mean scores of the intervention group improved significantly (P < 0.001). No statistically significant difference was observed, however, when comparing the intervention and control groups in terms of the level of adjustment to old age and health-related quality of life, either at baseline or following the intervention (P > 0.05).

CONCLUSION

The results of this study indicate that progressive muscle relaxation can increase adaptation to old age and the quality of life and of older people in a nursing home.

Investigating the effects of a virtual reality-based stress management programme on inpatients with mental disorders: A pilot randomised controlled trial

This study aimed to examine the effects and feasibility of a virtual screen-based stress management programme (V-DESSERTS) on inpatients with mental disorders. A single-blinded, pilot randomised controlled trial was conducted in a tertiary hospital in Singapore. Convenience sampling was used and participants were randomised into either the intervention group or the waitlisted control group (WL). The intervention group received individual-based, twice-daily sessions of the programme. Each session comprised education and virtual screen-based relaxation practice. Data were collected through self-reported questionnaires and physiological measures. The intervention group showed a significant increase in perceived relaxation and knowledge in comparison with the WL group. However, inconclusive results were observed on subjective and objective stress. The findings in this study indicated that the V-DESSERTS programme is feasible to be implemented for patients with schizophrenia, depression and bipolar disorders.

The Effectiveness of Group-based Cognitive Hypnotherapy on the Psychological Well-being of Patients with Multiple Sclerosis: A Randomized Clinical Trial

Multiple sclerosis is a chronic, demyelinating disease of the central nervous system mainly affecting young adults. In addition to physical problems, the patients suffer from many psychological problems affecting their psychological well-being. The aim of the present study was to determine the effectiveness of group-based cognitive hypnotherapy on the psychological well-being of patients suffering from multiple sclerosis. This study was designed as a clinical trial with a pretest-posttest control group. From 60 patients diagnosed with multiple sclerosis referred to Beheshti hospital in Yasuj, Iran, 45 patients who met the inclusion criteria were selected by the convenience sampling method. The patients were randomly assigned to intervention (23 individuals) and control (22 individuals) groups through stratified random allocation. After completing the Ryff Scales of Psychological Well-Being, the intervention group attended eight sessions of group-based cognitive hypnotherapy on a weekly basis. The control group did not attend any intervention sessions. At the end of the eight intervention sessions, both groups completed the Ryff's Scale of Psychological Well-being again. The collected data were analyzed using the SPSS software (Version 23). Analysis of Covariance (ANCOVA) and two-way Analysis of variance (ANOVA) tests were used in order to compare the groups. The results indicated that cognitive hypnotherapy had a significant effect on the total score of psychological well-being (F (45, 1) = 6.07, p = .018, η2 = 0.12) and the dimension of environmental mastery (p < .05). Therefore, it is recommended to use hypnotherapy to promote the psychological well-being of patients suffering from multiple sclerosis.

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.

The neural substrates responsible for how trait anxiety affects delay discounting: Right hippocampal and cerebellar connectivity with bistable right inferior parietal lobule

Delay discounting, an indicator of impulsivity, refers to the extent of devaluing future rewards. Studies have found that individuals with trait anxiety generally depreciate the later larger rewards, showing steeper delay discounting rates. However, little is known about the neural substrates responsible for how trait anxiety affects individuals' delay discounting. To address this question, we employed the voxel-based morphometry (VBM) and resting-state functional connectivity (RSFC) methods to explore the neural substrates of trait anxiety responsible for delay discounting. Behavioral results showed that trait anxiety was significantly positively correlated with delay discounting rates. The VBM analysis revealed that gray matter volumes of the right hippocampus (RHPC) and right cerebellum (RCere) were significantly positively correlated with trait anxiety. Moreover, the RSFC results showed that bistable right inferior parietal lobule (RIPL) connectivity with the RHPC and RCere were all inversely associated with trait anxiety. More importantly, mediation analysis indicated that trait anxiety played a completely mediating role in the relation between functional connectivity of RHPC-RIPL and RCere-RIPL and delay discounting. These results suggested that bistable RIPL connectivity with RHPC and RCere could be neural substrates underlying the effect of trait anxiety on delay discounting. On the whole, the current study yields insights into how trait anxiety affects delay discounting and provides a novel account from a neural basis perspective.

Integrative Body-Mind-Spirit (I-BMS) Practices for Schizophrenia: An Outcome Literature Review on Randomized Controlled Trials

Prior reviews show that certain complementary and alternative practices are promising for patients with schizophrenia. The aim of this study is to review the outcome literature on intervention studies using integrative body-mind-spirit (I-BMS) practices on schizophrenia. This is an outcome literature review of randomized controlled trials (RCTs) on I-BMS practices from 2004 to 2016. The review used a modified Delphi List to assess methodological rigor and the California Evidence-Based Clearinghouse Scientific Rating Scale to evaluate the level of research support for each identified I-BMS practice. This review identified 13 RCTs of I-BMS practices, including mindfulness interventions (5), yoga (3), tai-chi (2), and relaxation (3). I-BMS practices were effective with medium to large effect sizes for alleviating symptoms, decreasing anxiety and stress, improving insight and mindfulness, subjective well-being and social/occupational functioning, as well as decreasing the frequency and duration of re-hospitalization. This review expands the knowledge base of treatment effectiveness pertaining to patients with schizophrenia.

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.

Cognitive Restructuring and Graded Behavioral Exposure for Persecutory Paranoia and Agoraphobic Anxiety in Complex Psychosis

Cognitive behavioral models of psychosis assert the notion of cognitive mediation, in which threat-oriented subjective misinterpretations of anomalous experiences lead to increased levels of emotional distress. Thus, paranoid appraisals of auditory hallucinations often result in hypervigilance and associated anxiety. The prevalence of diagnostic comorbidity between psychosis and anxiety disorders has been shown to be considerable. Among the evidence-based psychological treatments for complex mental ill-health, Cognitive Behavioral Therapy for psychosis (CBTp) has been supported with particularly promising research outcomes. Yet, despite such encouraging empirical data, the treatment provision often remains insufficient, predominantly among individuals with more acute presentations. Likewise, literature demonstrating the actual utilization of CBTp with complex psychoses appears above all relevant to the daily clinical practice in the specialism of severe mental ill-health. This methodologically rigorous case study describes a successful implementation of CBTp undertaken with a socially withdrawn individual diagnosed with paranoid schizophrenia and comorbid agoraphobic anxiety disorder. The intervention focused on cognitive restructuring of paranoid appraisals of voices and graded behavioral exposure to anxiety-inducing stimuli. Standardized measurement, behavior frequency sampling, and subjective data were utilized to evaluate the outcomes, indicating a considerable reduction in both paranoia and associated anxiety, and an overall improvement in the client’s behavioral and interpersonal functioning. The article highlights the importance of direct intellectual engagement with the content of paranoia, alongside methodically facilitated graded behavioral exposure and response prevention in the treatment of severe, socially debilitating psychoses with comorbid mood disorders.

The effect of progressive muscle relaxation on cancer patients' self-efficacy

BACKGROUND AND PURPOSE

Self-efficacy is considered as one of the influential parameters affecting the health of patients. This study aimed to investigate the effect of relaxation techniques on self-efficacy of patients suffering from cancer.

MATERIALS AND METHODS

This study was a clinical trial in which 80 patients suffering from cancer were randomly assigned to two groups of experimental and control. Data collection instruments consisted of demographic information and Strategies Used by People to Promote Health questionnaires. In the experimental group, the patients performed relaxation techniques once a day for 30 min over two months. In the control group, the patients received the routine care.

RESULTS

A statistically significant difference was observed between the mean self-efficacy indices in the experimental group (p = 0.001). There was no significant difference in the control group (p = 0.3).

CONCLUSION

Muscle relaxation can enhance self-efficacy of cancer patients. Therefore, it can be used as an alternative method for patients who are willing to use this technique.

The Effect of Cognitive Behavioral Interventions on Depression and Anxiety Symptoms in Patients with Schizophrenia Spectrum Disorders: A Systematic Review

Depression and anxiety are prominent comorbid disorders in psychosis and relevant to psychotic symptom formation and maintenance. This poses the question of whether psychological interventions are effective in improving symptoms of depression and anxiety in patients with psychosis. A systematic review of the literature identified 14 studies evaluating a broad range of interventions targeting depression, anxiety, and posttraumatic stress disorder in patients with psychosis. The reviewed studies support the effectiveness of cognitive-behavioral interventions in improving the target symptoms. Further research is needed to examine whether the effects carry over to psychotic symptoms in the long term.

Perspectives on the Happiness of Community-Dwelling Elderly in Korea

OBJECTIVE

A community survey was performed to investigate the factors and perspectives associated with happiness among the elderly in Korea (≥60 years).

METHODS

Eight hundred volunteers selected from participants in the Ansan Geriatric study (AGE study) were enrolled, and 706 completed the survey. The Happiness Questionnaire (HQ), which asks four questions about happiness, was administered. To explore the relationship between happiness and depression, the Geriatric Depression Scale (GDS) and the Beck Depression Inventory (BDI) also were administered.

RESULTS

The participants' average level of happiness, determined using a 100-mm visual analogue scale (VAS) of the HQ, was 64.7±26.0. The happiest situations for most people were "getting together with family" (23.8%) and "living in peace with family members (well-being)" (13.2%). Frequent reasons for not being happy were "worsened health condition" (28.7% of the not-happy group), "economic problems of their own" (16.5%), and "economic problems of their children" (14.8%). The participants' choices regarding the essential conditions for happiness were "good health" (65.3%) and "being with family" (20.5%). The BDI and GDS scores were negatively related to the happiness score. A preliminary scale [Happy (Haeng-Bok, ) aging scale] based on the HQ for measuring the happiness level of the Korean elderly was suggested for follow-up studies.

CONCLUSION

The most important factors determining the happiness of the community-dwelling elderly in Korea were good family relationships, economic stability, and good health. A higher depression score negatively impacted happiness among Korean elders. Further studies on the factors in their happiness are required.

Self-relaxation training can improve sleep quality and cognitive functions in the older: a one-year randomised controlled trial

AIMS AND OBJECTIVE

To evaluate the effects of self-relaxation training on sleep quality and cognitive functions in the older.

BACKGROUND

Ageing causes declines in sleep quality and cognitive functions in older adults, and decreased sleep quality also accelerates declines in cognitive functions. Therefore, it is necessary to find cost-effective interventions to enhance sleep quality in the older, thereby improving their cognitive functions or delaying cognitive decline.

DESIGN

Randomised controlled study.

METHODS

The study was conducted between July 2010 and June 2011 at Wangyuehu Community in Changsha, China. Eighty older adults with reduced sleep quality were selected and randomly assigned to experimental (n = 40) or control (n = 40) group. Subjects in the experimental group received self-relaxation training including progressive muscle relaxation and meditation based on sleep hygiene education, while the control group received sleep hygiene education only. Sleep quality and cognitive functions of the two groups were measured prior to training and at the end of the 3rd, 6th and 12th months using four reliable and valid questionnaires.

RESULTS

Repeated measures anova revealed that the self-relaxation training had significant main effect as well as interaction effect with time on sleep quality and cognitive functions. Except for scores of Epworth Sleepiness Scale, Mini-Mental State Examination and number memory, time had significant main effect on scores of Pittsburgh Sleep Quality Index, picture memory, associative memory and understanding memory.

CONCLUSION

Self-relaxation training can improve sleep quality and cognitive functions in the older.

RELEVANCE TO CLINICAL PRACTICE

Self-relaxation training is a non-invasive, simple and inexpensive therapeutic method of improving sleep quality and cognitive functions in community-dwelling older people.

Anxiety comorbidity in schizophrenia

Diagnostic and treatment hierarchical reductionisms have led to an oversight of anxiety syndromes in schizophrenia. Nevertheless, recent data have indicated that anxiety can be a significant source of morbidity in this patient group. This paper reviews current knowledge concerning anxiety comorbidity in schizophrenia, its epidemiology, course, and treatment. A computerized search of the literature published from 1966 to July 2012 was conducted on Medline. Comorbid anxiety disorders are present in 38.3% of subjects with schizophrenia spectrum disorders. The most common anxiety disorder is social phobia followed by post-traumatic stress disorder and obsessive compulsive disorder. The presence and severity of symptoms of anxiety are associated with more severe clinical features and poorer outcomes. Available literature on the treatment consists primarily of case reports and open trials. Fragments of data support the notion of treating these anxiety states and syndromes as co-occurring clinical conditions with adjunctive medications and psychosocial interventions. However, additional work remains to be done on this issue before firm conclusions can be drawn.

The effect of Benson's relaxation technique on the quality of sleep of Iranian hemodialysis patients: a randomized trial

OBJECTIVE

This study was performed to evaluate the effectiveness of Benson's relaxation technique in the quality of sleep of hemodialysis patients.

DESIGN

It was a randomized controlled trial with a pre-post-test design. A total of 86 hemodialysis patients referring to hemodialysis units were assigned to either the intervention (receiving Benson's relaxation technique) or the control group (routine care) through block randomization.

SETTING

The study was performed in two hemodialysis units affiliated to Shiraz University of Medical Sciences, Shiraz, Iran.

INTERVENTION

The patients in the intervention group listened to the audiotape of Benson's relaxation technique twice a day each time for twenty minutes for eight weeks.

MAIN OUTCOME MEASURES

The global score of Pittsburgh Sleep Quality Index (PSQI) as well as its components was computed in both the intervention and the control group before and at the 8th week of the intervention.

RESULTS

The results of ANCOVA indicated significant differences between the two groups regarding the scores of Pittsburgh Sleep Quality Index subscales, such as sleep disturbance, daytime dysfunction, the use of sleep medication, and subjective sleep quality and as well as its global scores at the 8th week of the intervention (p<0.05).

CONCLUSIONS

This study highlighted the importance of Benson's relaxation technique in improvement of the sleep quality of the patients on hemodialysis. Thus, educational sessions are recommended to be planned on this cost effective and easy to use relaxation technique in order to improve hemodialysis patients' sleep quality. Further studies are needed to assess the effectiveness of this technique in other groups of patients.

Emotion regulation through execution, observation, and imagery of emotional movements

According to Damasio's somatic marker hypothesis, emotions are generated by conveying the current state of the body to the brain through interoceptive and proprioceptive afferent input. The resulting brain activation patterns represent unconscious emotions and correlate with subjective feelings. This proposition implies a corollary that the deliberate control of motor behavior could regulate feelings. We tested this possibility, hypothesizing that engaging in movements associated with a certain emotion would enhance that emotion and/or the corresponding valence. Furthermore, because motor imagery and observation are thought to activate the same mirror-neuron network engaged during motor execution, they might also activate the same emotional processing circuits, leading to similar emotional effects. Therefore, we measured the effects of motor execution, motor imagery and observation of whole-body dynamic expressions of emotions (happiness, sadness, fear) on affective state. All three tasks enhanced the corresponding affective state, indicating their potential to regulate emotions.

Progressive muscle relaxation in persons with schizophrenia: a systematic review of randomized controlled trials

Objective:

The aim of this systematic review was to assess the effectiveness of progressive muscle relaxation on psychological distress and anxiety symptoms and on response/remission for people with schizophrenia.

Methods:

Randomized controlled trials were considered if they investigated progressive muscle relaxation in patients with schizophrenia. EMBASE, PsycINFO, PubMed, ISI Web of Science, CINAHL, PEDro and Cochrane Library were searched. The selection of studies, data extraction and quality assessment were performed independently by two reviewers.

Results:

Three randomized controlled trials involving 146 patients met the inclusion criteria. Progressive muscle relaxation can acutely reduce state anxiety and psychological distress and improve subjective well-being. No studies investigated the evidence for progressive muscle relaxation as an add-on treatment for general psychopathology and for positive or negative symptoms. Also, no studies assessed the value of progressive muscle relaxation in longer-term treatment and for relapse prevention. There were no data to draw any conclusions about progressive muscle relaxation in comparison with other treatment modalities. None of the studies encountered adverse events. Dose-response relationships could not be determined.

Conclusion:

Progressive muscle relaxation might be a useful add-on treatment to reduce state anxiety and psychological distress and improve subjective well-being in persons with schizophrenia.

Effects of an exercise programme on anxiety in adults with intellectual disabilities

Although high anxiety is common in people with intellectual disabilities (ID) and the anxiolytic effects of exercise have been systematically recognised in clinical and non-clinical populations, research is scant concerning the role played by exercise on anxiety in people with ID. The purpose of this study was to investigate the effects of a 12-week exercise programme on anxiety states in a group of adults with ID. Twenty-seven individuals with mild to moderate ID were randomly assigned to an exercise group or a control group. The Zung Self-Rating Anxiety Scale adapted for individuals with ID and the State-Trait Anxiety Inventory form Y were used to assess trait and state anxiety. In comparison with the control group, the anxiety scores of people in the exercise group decreased significantly over time.

Systematic review of the benefits of physical therapy within a multidisciplinary care approach for people with schizophrenia

BACKGROUND

Although schizophrenia is the fifth leading cause of disability-adjusted life years worldwide in people aged 15 to 44 years, the clinical evidence of physical therapy as a complementary treatment remains largely unknown.

PURPOSE

The purpose of this study was to systematically review randomized controlled trials (RCTs) evaluating the effectiveness of physical therapy for people with schizophrenia.

DATA SOURCES

EMBASE, PsycINFO, PubMed, ISI Web of Science, Cumulative Index to Nursing and Allied Health Literature (CINAHL), Physiotherapy Evidence Database (PEDro), and the Cochrane Library were searched from their inception until July 1, 2011, for relevant RCTs. In addition, manual search strategies were used.

STUDY SELECTION

Two reviewers independently determined study eligibility on the basis of inclusion criteria.

DATA EXTRACTION

Reviewers rated study quality and extracted information about study methods, design, intervention, and results.

DATA SYNTHESIS

Ten RCTs met all selection criteria; 6 of these studies addressed the use of aerobic and strength exercises. In 2 of these studies, yoga techniques also were investigated. Four studies addressed the use of progressive muscle relaxation. There is evidence that aerobic and strength exercises and yoga reduce psychiatric symptoms, state anxiety, and psychological distress and improve health-related quality of life, that aerobic exercise improves short-term memory, and that progressive muscle relaxation reduces state anxiety and psychological distress.

LIMITATIONS

The heterogeneity of the interventions and the small sample sizes of the included studies limit overall conclusions and highlight the need for further research.

CONCLUSIONS

Physical therapy offers added value in the multidisciplinary care of people with schizophrenia.
