Brief internet-based cognitive behavior therapy program with a supplement drink improved anxiety and somatic symptoms in Japanese workers

Background

Self-help cognitive behavior therapy (CBT) is a useful approach for the treatment of psychological problems. Recent research on the effectiveness of self-help internet-based CBT (ICBT) indicates that the paradigm moderately improves psychological problems. Furthermore, previous studies have shown that food and drinks containing supplements improve various health conditions. We investigated the effect of a brief self-help ICBT administered with a supplement drink on psychological well-being and somatic symptoms.

Methods

In total, 101 healthy workers were enrolled in the 4-week ICBT program, which consisted of psychoeducation on stress management, behavior activation, and cognitive restructuring. The supplement soft drink was taken every day during the program. The participants were instructed to watch on-demand video clips and read the self-help guidebook and supporting comic strip weekly on the Internet or smartphone. The Japanese version of the Profile of Mood States (POMS) was administered before and after completion of the program. Scores on the POMS tension-anxiety (POMS-TA), depression (POMS-D), and fatigue (POMS-F) subscales were used to assess the effect of the program. Somatic symptoms were assessed using the Brief Job Stress Questionnaire.

Results

In total, 75 participants continued the program for 4 weeks; however, of those, 27 failed to complete all weekly tasks or meet the post-assessment deadlines. Therefore, the data of 48 participants were included in the analysis. Pre-post intervention comparisons using paired t-tests revealed significant improvement on the POMS-TA, but not the POMS-D or POMS-F subscales. Moreover, participants reported a significant reduction in the severity of low back pain.

Conclusion

Our brief intervention moderately improved anxiety levels and the symptom of low back pain. These findings suggest that the brief ICBT program is effective in non-patient populations. Future directions for brief ICBT are discussed.

L-carnosine as an enhancer to computerized cognitive behaviour therapy in Japanese workers,an unjustified claim

This letter comments on the conclusion drawn by Shirotsuki et al. (2017) in their article entitled “The effect for Japanese workers of a self-help computerized cognitive behaviour therapy program with a supplement soft drink”, recently published in BioPsychoSocial Medicine. The authors concluded that their drink, containing L-carnosine, enhances the effects of a computerized cognitive-behavioural therapy (CCBT) on the psychological well-being of healthy Japanese workers. Yet, we argue that their conclusion is unfounded given their results and the methodological shortcomings of their study. Briefly, while the authors reported improvement on the tension-anxiety subscale of the Profile of Mood States (POMS) in the CCBT only group, they also observed a lack of improvement on this subscale in the CCBT+L-carnosine group suggesting that the drink washes out this beneficial effect of CCBT. Methodological issues include the uncontrolled levels of L-carnosine metabolized by participants jeopardize the study’s internal validity. Also, the clinical meaningfulness of the findings seems dubious as post-treatment scores remained within the range of the general Japanese population. Consequently, we argue that Shirotsuki et al.’s study should be re-conducted before drawing any valid conclusion.     

Feasibility of guided cognitive behaviour therapy (CBT) self-help for childhood anxiety disorders in primary care

Anxiety disorders in childhood are common, disabling and run a chronic course. Cognitive behaviour therapy (CBT) is effective but expensive and trained therapists are scarce. Guided self-help treatments may be a means of widening access to treatment. This study aimed to examine the feasibility of guided CBT self-help in primary care for childhood anxiety disorders, specifically in terms of therapist adherence, patient and therapist satisfaction and clinical gain.Participants were children aged between five and 12 years referred to two primary child and adolescent mental health services (PCAMHSs) in Oxfordshire, UK, who met diagnostic criteria for a primary anxiety disorder. Of the 52 eligible children, 41 anxious children were assessed for anxiety severity and interference before and after receiving CBT self-help delivered via a parent (total therapy time = five hours) by primary mental health workers (PMHWs). Therapy sessions were rated for treatment adherence and parents and PMHWs completed satisfaction questionnaires after treatment completion. Over 80% of therapy sessions were rated at a high level of treatment adherence. Parents and PMHWs reported high satisfaction with the treatment. Sixty-one percent of the children assessed no longer met the criteria for their primary anxiety disorder diagnosis following treatment, and 76% were rated as 'much'/'very much' improved on the Clinical Global Impression-Improvement (CGI-I) scale. There were significant reductions on parent and child report measures of anxiety symptoms, interference and depression. Preliminary exploration indicated that parental anxiety was associated with child treatment outcome. The findings suggest that guided CBT self-help represents a promising treatment for childhood anxiety in primary care.     

Effectiveness of cognitive behaviour therapy for the treatment of catastrophisation in patients with fibromyalgia: a randomised controlled trial

Introduction  

No randomised, controlled trials have been conducted to date on the efficacy of psychological and pharmacological treatments of pain catastrophising (PC) in patients with fibromyalgia. Our aim in this study was to assess the effectiveness of cognitive-behaviour therapy (CBT) and the recommended pharmacological treatment (RPT) compared with treatment as usual (TAU) at the primary care level for the treatment of PC in fibromyalgia patients.     

The effect of a taurine-containing drink on performance in 10 endurance-athletes

Summary To determine the effect of a taurine-enriched drink Red Bull on performance, 10 endurance-athletes performed three trials. After 60 min. cycling at approximately 70% VO₂ max, the subjects pedalled to exhaustion on a cycle ergometer. During each exercise, the subjects received 500 ml of a test-drink after 30 min. submaximal cycling: Red Bull without taurine, without glucuronolacton (U1), Red Bull without taurine, without glucuronolacton, without caffeine (U2) and Red Bull original drink containing taurine, glucuronolacton and caffeine (U3).The heart rate level was significantly lower in U3 (p = 0,0031) 15 min. after application. The plasma catecholamines increased slightly from begin of exercise to 15 min. after application of the drinks in all trials but remained on a significantly lower level in U3 (epinephrine (p = 0,0011) and norepinephrine (p = 0,0003). Endurance time was significantly longer with Red Bull original in U3 (p = 0,015). The results of this study show a positive effect of a taurine-containing drink on hormonal responses which leads to a higher performance.     

Comparative, clinical feasibility study of three tools for delivery of cognitive behavioural therapy for mild to moderate depression and anxiety provided on a self-help basis

Background In response to a research recommendation made by a UK healthcare policy agency (National Institute for Health and Clinical Excellence (NICE)), this study compared the effectiveness of computer‐based cognitive behavioural therapy (CBT) with other self‐help treatment options for mild to moderate depression and anxiety.Method Comparative, clinical feasibility study of three self‐help CBT tools with six‐month follow‐up. Out of an initial sample of 180 adults referred by their general practitioners, 100 met the inclusion criteria and after consenting to take part were allocated one of three self‐help CBT tools: the Beating the Blues® (BtB) computer programme;¹ workbooks on overcoming depression and anxiety; and the Livinglifetothefull free access internet website.²Results Only 50 of the 100 consented participants completed the allocated intervention protocols, however, drop‐out rates were not significantly different between the groups of participants allocated each of the three self‐help CBT tools. Adults aged over 24 years (χ² = 14.5; df = 2; P = 0.001) and with symptom duration greater than four years (χ² = 3.96; df = 1; P = 0.047) were significantly more likely to complete any of the three interventions. There was a highly significant reduction in mean Clinical Outcomes in Routine Evaluation–Outcome Measure (CORE–OM) score at week eight compared to entry in all three groups (t (49) = 9.150; P ≤0.001). Adjusting for entry scores, there was no significant difference between the three groups in CORE–OM score improvement at week eight. There was no significant association between CORE–OM score improvement at week eight and number of general practitioner (GP) consultations at six months. There was no significant association between whether participants completed the programme and number of GP consultations at six months.Conclusions The results demonstrated that within a two‐month follow‐up period, three different tools delivering self‐help CBT all produced significant clinical benefit for adults with mild to moderate depression and anxiety. The study had limited statistical power, but none of the modalities for delivering supported self‐help CBT appeared superior to another. There was no evidence to suggest that any of these interventions would be likely to reduce subsequent service uptake. Nevertheless, this pilot study has shown sufficient benefit from each of the self‐administered CBT tools to justify larger trials of their use.     

Effects of internet-based guided self-help problem-solving therapy for adolescents with depression and anxiety: a randomized controlled trial

Background

Symptoms of depression and anxiety are highly prevalent in adolescence and they are the cause of considerable suffering. Even so, adolescents are not inclined to seek professional help for emotional problems. Internet-based preventive interventions have been suggested as a feasible method of providing appropriate care to adolescents with internalizing symptoms. The objective of this study was to evaluate the effects of preventive Internet-based (guided) self-help problem-solving therapy (PST) for adolescents reporting mild to moderate symptoms of depression and/or anxiety as compared to a waiting list control group (WL).

Methodology/Principal Findings

A total of 45 participants were randomized to the 2 conditions. PST consisted of 5 weekly lessons. Participants were supported by e-mail. Self-report measures of depression and anxiety were filled in at baseline and after 3 weeks, 5 weeks, and 4 months. Of the 45 participants, 28 (62.2%) completed questionnaires after 3 weeks, 28 (62.2%) after 5 weeks, and 27 (60%) after 4 months. Hierarchical linear modeling analyses revealed overall improvement over time for both groups on depressive and anxiety symptoms. However, no significant group x time interactions were found. No differences were found between completers and non-completers.

Conclusions/Significance

Results show that depressive and anxiety symptoms declined in both groups. No support was found, however, for the assumption that Internet-based PST was efficacious in reducing depression and anxiety in comparison to the waiting list control group. This finding could represent lack of power.

The effect of transfer factor therapy on tumor immunity in alveolar soft part sarcoma

A young man with alveolar soft part sarcoma and his identical twin were studied in terms of immunologic response to the patient's tumor homogenate. The lymphocytes from both twins underwent lymphoblastic transformation to tumor homogenate but only the healthy twin's lymphocytes released demonstrable migration inhibition factor (MIF) to the tumor preparation. Transfer factor was prepared from the healthy twin and administered to the tumor-bearing twin. A total dose of transfer factor equivalent to 45 × 10⁸ lymphocytes given in three separate doses produced a persistently positive MIF assay in the patient. The tumor neither regressed nor progressed during the 6-month period after transfer factor therapy.

The effect of quercetin, a widely distributed flavonoid in food and drink, on cytosolic aldehyde dehydrogenase: a comparison with the effect of diethylstilboestrol

Quercetin is a flavonoid found in red wine and many other dietary sources. Observations concerning the state of ionisation and the stability of the compound over a range of pH are presented. Quercetin is a potent inhibitor of cytosolic aldehyde dehydrogenase at physiological pH when the concentration of either the substrate or the cofactor is relatively low, but it has an activatory effect when the concentrations of substrate and cofactor are both high (1 mM). Gel filtration experiments show that quercetin binds very tightly to the enzyme under conditions where the compound is neutral and when it is ionised. The binding is less in the presence of NAD(+). Quercetin cuts down the ability of the resorufin anion to bind to the enzyme. The observations are explained by a model in which quercetin binds competitively to both the coenzyme-binding site and the aldehyde-binding site; binding in the latter location, when the enzyme is in the form of the E-NADH complex, accounts for the activation. The effects of quercetin are significantly different in some respects from those of diethylstilboestrol; this is explained by the latter being able to bind to the aldehyde site but not the NAD(+) site. The possibility that quercetin may affect aldehyde dehydrogenase in vivo is discussed.     

Adaptive pacing, cognitive behaviour therapy, graded exercise, and specialist medical care for chronic fatigue syndrome: a cost-effectiveness analysis

Background

The PACE trial compared the effectiveness of adding adaptive pacing therapy (APT), cognitive behaviour therapy (CBT), or graded exercise therapy (GET), to specialist medical care (SMC) for patients with chronic fatigue syndrome. This paper reports the relative cost-effectiveness of these treatments in terms of quality adjusted life years (QALYs) and improvements in fatigue and physical function.

Methods

Resource use was measured and costs calculated. Healthcare and societal costs (healthcare plus lost production and unpaid informal care) were combined with QALYs gained, and changes in fatigue and disability; incremental cost-effectiveness ratios (ICERs) were computed.

Results

SMC patients had significantly lower healthcare costs than those receiving APT, CBT and GET. If society is willing to value a QALY at £30,000 there is a 62.7% likelihood that CBT is the most cost-effective therapy, a 26.8% likelihood that GET is most cost effective, 2.6% that APT is most cost-effective and 7.9% that SMC alone is most cost-effective. Compared to SMC alone, the incremental healthcare cost per QALY was £18,374 for CBT, £23,615 for GET and £55,235 for APT. From a societal perspective CBT has a 59.5% likelihood of being the most cost-effective, GET 34.8%, APT 0.2% and SMC alone 5.5%. CBT and GET dominated SMC, while APT had a cost per QALY of £127,047. ICERs using reductions in fatigue and disability as outcomes largely mirrored these findings.

Conclusions

Comparing the four treatments using a health care perspective, CBT had the greatest probability of being the most cost-effective followed by GET. APT had a lower probability of being the most cost-effective option than SMC alone. The relative cost-effectiveness was even greater from a societal perspective as additional cost savings due to reduced need for informal care were likely.     

Effectiveness of teaching general practitioners skills in brief cognitive behaviour therapy to treat patients with depression: randomised controlled trial

ObjectiveTo assess the effectiveness of teaching general practitioners skills in brief cognitive behaviour therapy.DesignParallel group, cluster randomised, controlled trial of an educational package on cognitive behaviour therapy.SettingGeneral practices in north London.Participants84 general practitioner principals and 272 patients attending their practices who scored above the threshold for psychological distress on the hospital anxiety and depression scale.InterventionA training package of four half days on brief cognitive behaviour therapy.ResultsDoctors'' knowledge of depression and attitudes towards its treatment showed no major difference between intervention and control groups after 6 months. The training had no discernible impact on patients'' outcomes.ConclusionGeneral practitioners may require more training and support than a basic educational package on brief cognitive behaviour therapy to acquire skills to help patients with depression.

What is already known on this topic

Trained professionals can deliver effective cognitive behaviour therapy to depressed patients presenting to general practitionersLimited evidence shows that cognitive behaviour therapy is effective when delivered by general practitioners who have received extensive instructionMost doctors do not have the time or inclination to carry out such comprehensive training

What this study adds

Basic training in brief cognitive behaviour therapy has little effect on general practitioners'' attitudes to the identification and treatment of depression or the outcome of their patients with emotional problemsGeneral practitioners may require more extensive training and support if they are to acquire skills in brief cognitive behaviour therapy that will have a positive impact on their patients     

The effect of a traditional dance training program on dynamic balance of individuals with mental retardation

The purpose of this study was to evaluate the influence of a Greek traditional dance training program on the dynamic balance of individuals with mental retardation (MR). A total of 17 individuals participated in this study. Ten individuals with mild or moderate MR and 7 individuals with mild or moderate MR who studied in special schools were assigned to intervention (MR-I) and control (MR-C) groups, respectively. Pretraining and posttraining exercise tests were performed to determine the dynamic balance ability. Dynamic balance ability was measured by means of a balance deck (Lafayette, Lafayette, IN, USA) in 30-, 45-, and 60-second intervals. The MR-I group underwent a 16-week Greek traditional dance training program at a frequency of 3 times per week and for a duration of 45 minutes per season. Posttraining results showed that the individuals with MR in the MR-I group improved during treatment, from their baseline scores on dynamic balance measurements (30 seconds: p < 0.01, 45 seconds: p < 0.05, 60 seconds: p < 0.05). The MR-C group did not show any improvement between the 2 measurements. In conclusion, individuals with MR may be able to improve their dynamic balance when performing a systematic and well-designed Greek traditional dance training program.     

The promise of cognitive behavior therapy for treatment of severe mental disorders: a review of recent developments

Cognitive behavior therapy (CBT), as exemplified by the model of psychotherapy developed and refined over the past 40 years by A.T. Beck and colleagues, is one of the treatments of first choice for ambulatory depressive and anxiety disorders. Over the past several decades, there have been vigorous efforts to adapt CBT for treatment of more severe mental disorders, including schizophrenia and the more chronic and/or treatment refractory mood disorders. These efforts have primarily studied CBT as an adjunctive therapy, i.e., in combination with pharmacotherapy. Given the several limitations of state‐of‐the‐art pharmacotherapies for these severe mental disorders, demonstration of clinically meaningful additive effects for CBT would have important implications for improving public health. This paper reviews the key developments in this important area of therapeutics, providing a summary of the current state of the art and suggesting directions for future research.     

The effect of perfusion on soft tissue mechanical properties: a computational model

Some simple finite element models were constructed to investigate the magnitude and character of changes in mechanical properties of very soft tissues due to the loss of perfusion. Changes in the apparent stress-strain curve were used to characterise the effect of simulated blood perfusion pressure on the engineering stress-strain curve. The results indicated that the blood to tissue volume ratio and the perfusion pressure have the strongest effect on the effective stress-strain response of a representative tissue cell. Tissue viscoelasticity increased the sensitivity of the system to perfusion pressure changes.
