Cost effectiveness of internet-based cognitive behaviour therapy and behavioural stress management for severe health anxiety

Brief digital self-care intervention for health anxiety in a Swedish Medical University Clinic: a prospective single-group feasibility study

OBJECTIVES

In routine psychiatric care in Stockholm, Sweden, a comprehensive therapist-guided intervention for clinically significant health anxiety is implemented. However, there is a need for more easily accessible self-care interventions to improve treatment dissemination. This study aimed to transform an existing therapist-guided digital intervention into a self-care intervention, reducing patient burden and used clinical resources while maintaining quality and safety.

DESIGN

An uncontrolled feasibility study.

SETTING

Conducted at Karolinska Institutet, a medical university in Sweden, with nationwide recruitment trough online advertisements.

PARTICIPANTS

Twenty-five adults used the self-care intervention and underwent telephone assessments, along with completing self-rated questionnaires.

INTERVENTION

The newly developed 8-week self-care intervention was designed to be user-friendly without therapist guidance, and to facilitate high levels of behavioural engagement.

PRIMARY AND SECONDARY OUTCOME MEASURES

Indicators of quality and safety, including changes in health anxiety severity (primary), clinician time, participant adherence, perceived credibility/satisfaction with the intervention and adverse events, were benchmarked against a previous study of the more comprehensive intervention it was based on.

RESULTS

Compared with the original guided intervention, the self-care intervention was condensed in terms of text (up to 70% less reading), duration (8 weeks instead of 12) and number of exercises. Quality indicators were similar to the original version. Most participants worked actively with core components in the self-care intervention. Within-group effects on health anxiety from pretreatment to the 3-month follow-up were large (g=1.37; 95% CI 0.74 to 2.00). No serious adverse events were reported.

CONCLUSIONS

This brief digital self-care intervention shows potential for increasing access to treatment for individuals with health anxiety while reducing the burden on patients and clinical resources. Future studies should investigate the optimal type of intervention and support for different individuals, and if non-inferiority can be established.

Effects of online mindfulness-based interventions (MBIs) on anxiety symptoms in adults: a systematic review and meta-analysis

BACKGROUND

An increasing number of studies have documented the effectiveness on various types of face-to-face and online mindfulness-based interventions (MBIs) in reducing anxiety among general population, but there is a scarcity of systematic reviews evaluating evidence of online MBIs on anxiety in adults. Therefore, we examined the effects of online mindfulness-based interventions (MBIs) on anxiety symptoms in adults and explored the moderating effects of participant, methods, and intervention characteristics.

METHODS

We systematically searched nine databases through May 2022 without date restrictions. Inclusion criteria were primary studies evaluating online mindfulness-based interventions with adults with anxiety measured as an outcome, a comparison group, and written in English. We used random-effects model to compute effect sizes (ESs) using Hedges' g, a forest plot, and Q and I² statistics as measures of heterogeneity; we also examined moderator analyses.

RESULTS

Twenty-six primary studies included 3,246 participants (39.9 ± 12.9 years old). Overall, online mindfulness-based interventions showed significantly improved anxiety (g = 0.35, 95%CI 0.09, 0.62, I² = 92%) compared to controls. With regards to moderators, researchers reported higher attrition, they reported less beneficial effects on anxiety symptoms (β=-0.001, Q_model=4.59, p = .032). No other quality indicators moderated the effects of online mindfulness-based interventions on anxiety.

CONCLUSION

Online mindfulness-based interventions improved anxiety symptoms in adult population. Thus, it might be used as adjunctive or alternative complementary treatment for adults. However, our findings must be interpreted with caution due to the low and unclear power of the sample in primary studies; hence, high-quality studies are needed to confirm our findings.

A Telehealth and Telepsychiatry Economic Cost Analysis Framework: Scoping Review

Introduction: Despite a good evidence base for telepsychiatry (TP), economic cost analyses are infrequent and vary in quality. Methods: A scoping review was conducted based on the research question, "From the perspective of an economic cost analysis for telehealth and telepsychiatry, what are the most meaningful ways to ensure a study/intervention improved clinical care, provided value to participants, had population level impact, and is sustainable?" The search in seven databases focused on keywords in four concept areas: (1) economic cost analysis, (2) evaluation, (3) telehealth and telepsychiatry, and (4) quantifiable health status outcomes. The authors reviewed the full-text articles based on the inclusion (Medical Subject Headings [MeSH] of the keywords) and exclusion criteria. Results: Of a total of 2,585 potential references, a total of 99 articles met the inclusion criteria. The evaluation of telehealth and TP has focused on access, quality, patient outcomes, feasibility, effectiveness, outcomes, and cost. Cost-effectiveness, cost-benefit, and other analytic models are more common with telehealth than TP studies, and these studies show favorable clinical, quality of life, and economic impact. A standard framework for economic cost analysis should include: an economist for planning, implementation, and evaluation; a tool kit or guideline; comprehensive analysis (e.g., cost-effectiveness or cost-benefit) with an incremental cost-effectiveness ratio; measures for health, quality of life, and utility outcomes for populations; methods to convert outcomes into economic benefits (e.g., monetary, quality of adjusted life year); broad perspective (e.g., societal perspective); sensitivity analysis for uncertainty in modeling; and adjustments for differential timing (e.g., discounting and future costs). Conclusions: Technology assessment and economic cost analysis-such as effectiveness and implementation science approaches-contribute to clinical, training, research, and other organizational missions. More research is needed with a framework that enables comparisons across studies and meta-analyses.

COVID-19 pandemic and telemental health policy reforms

Many patients with mental disorders lack access to care mainly due to provider shortages. Coronavirus disease 2019 (COVID-19) pandemic significantly raised the prevalence of anxiety, depression, substance use disorder and suicidal thoughts among people. Mandated social distancing, and higher incidence of mental disorders increased the demand for Telemental Health (TMH). TMH expands access to care and can be an effective alternative to the costly conventional mental health care. However, there are barriers to the adoption of TMH such as reimbursement challenges, and licensure restrictions. During the COVID-19 pandemic, some policies and regulations changed to address the increase in TMH demand. The federal government increased funding for the new telehealth initiatives and more states legalized the interstate practice for psychologists. Medicare waived telehealth co-payments, reimbursed audio-only visits, and required payment parities between virtual and in-person visits. Nevertheless, Medicare maintained in-person visit prerequisite within the six months prior to the first time only for mental health treatments which can act as a hindrance. Additionally, four more states required telehealth coverage, 33 states required Medicaid plans, and 21 states required private insurers to cover TMH services. Ten states mandated payment parity for private insurers, and four states eliminated cost-sharing for telehealth services. Currently, 21 states are implementing payment parity on a permanent basis. During the pandemic, 78% of Mental health providers integrated TMH services into their practice. Despite the decline in use of telehealth for other health conditions after the pandemic peak, TMH use has remained strong representing 36% of outpatient visits. TMH is beneficial to patients in terms of cost and time saving; thus, the beneficiary regulatory changes should be sustained. Further well-designed studies are needed on the cost-effectiveness of telehealth interventions, and policymakers need to collect more data to decide whether and how to keep these changes permanently for TMH.

Systematic review of economic evaluations for internet- and mobile-based interventions for mental health problems

In view of the staggering disease and economic burden of mental disorders, internet and mobile-based interventions (IMIs) targeting mental disorders have often been touted to be cost-effective; however, available evidence is inconclusive and outdated. This review aimed to provide an overview of the cost-effectiveness of IMIs for mental disorders and symptoms. A systematic search was conducted for trial-based economic evaluations published before 10th May 2021. Electronic databases (including MEDLINE, PsycINFO, CENTRAL, PSYNDEX, and NHS Economic Evaluations Database) were searched for randomized controlled trials examining IMIs targeting mental disorders and symptoms and conducting a full health economic evaluation. Methodological quality and risk of bias were assessed. Cost-effectiveness was assumed at or below £30,000 per quality-adjusted life year gained. Of the 4044 studies, 36 economic evaluations were reviewed. Guided IMIs were likely to be cost-effective in depression and anxiety. The quality of most evaluations was good, albeit with some risks of bias. Heterogeneity across studies was high because of factors such as different costing methods, design, comparison groups, and outcomes used. IMIs for anxiety and depression have potential to be cost-effective. However, more research is needed into unguided (preventive) IMIs with active control conditions (e.g., treatment as usual) and longer time horizon across a wider range of disorders.Trial registration: PROSPERO Registration No. CRD42018093808.

One-session treatment compared with multisession CBT in children aged 7–16 years with specific phobias: the ASPECT non-inferiority RCT

Background

Up to 10% of children and young people have a specific phobia that can significantly affect their mental health, development and daily functioning. Cognitive–behavioural therapy-based interventions remain the dominant treatment, but limitations to their provision warrant investigation into low-intensity alternatives. One-session treatment is one such alternative that shares cognitive–behavioural therapy principles but has a shorter treatment period.

Objective

This research investigated the non-inferiority of one-session treatment to cognitive–behavioural therapy for treating specific phobias in children and young people. The acceptability and cost-effectiveness of one-session treatment were examined.

Design

A pragmatic, multicentre, non-inferiority randomised controlled trial, with embedded economic and qualitative evaluations.

Settings

There were 26 sites, including 12 NHS trusts.

Participants

Participants were aged 7–16 years and had a specific phobia defined in accordance with established international clinical criteria.

Interventions

Participants were randomised 1 : 1 to receive one-session treatment or usual-care cognitive–behavioural therapy, and were stratified according to age and phobia severity. Outcome assessors remained blind to treatment allocation.

Main outcome measures

The primary outcome measure was the Behavioural Avoidance Task at 6 months’ follow-up. Secondary outcomes included the Anxiety Disorder Interview Schedule, Child Anxiety Impact Scale, Revised Children’s Anxiety and Depression Scale, a goal-based outcome measure, Child Health Utility 9D, EuroQol-5 Dimensions Youth version and resource usage. Treatment fidelity was assessed using the Cognitive Behaviour Therapy Scale for Children and Young People and the One-Session Treatment Rating Scale.

Results

A total of 274 participants were recruited, with 268 participants randomised to one-session treatment (n = 134) or cognitive–behavioural therapy (n = 134). A total of 197 participants contributed some data, with 149 participants in the intention-to-treat analysis and 113 in the per-protocol analysis. Mean Behavioural Avoidance Task scores at 6 months were similar across treatment groups when both intention-to-treat and per-protocol analyses were applied [cognitive–behavioural therapy: 7.1 (intention to treat), 7.4 (per protocol); one-session treatment: 7.4 (intention to treat), 7.6 (per protocol); on the standardised scale adjusted mean difference for cognitive–behavioural therapy compared with one-session treatment –0.123, 95% confidence interval –0.449 to 0.202 (intention to treat), mean difference –0.204, 95% confidence interval –0.579 to 0.171 (per protocol)]. These findings were wholly below the standardised non-inferiority limit of 0.4, which suggests that one-session treatment is non-inferior to cognitive–behavioural therapy. No between-group differences in secondary outcome measures were found. The health economics evaluation suggested that, compared with cognitive–behavioural therapy, one-session treatment marginally decreased the mean service use costs and maintained similar mean quality-adjusted life-year improvement. Nested qualitative evaluation found one-session treatment to be considered acceptable by those who received it, their parents/guardians and clinicians. No adverse events occurred as a result of phobia treatment.

Limitations

The COVID-19 pandemic meant that 48 children and young people could not complete the primary outcome measure. Service waiting times resulted in some participants not starting therapy before follow-up.

Conclusions

One-session treatment for specific phobia in UK-based child mental health treatment centres is as clinically effective as multisession cognitive–behavioural therapy and highly likely to be cost-saving. Future work could involve improving the implementation of one-session treatment through training and commissioning of improved care pathways.

Cost-effectiveness of varying degrees and models of therapist-assisted transdiagnostic internet-delivered cognitive behaviour therapy: Evidence from a randomized controlled trial

In routine care, Internet-delivered Cognitive Behaviour Therapy (ICBT) is often delivered with therapist support via emails/phone calls, but the cost-effectiveness of varying amounts of therapist support or having therapists specialized in ICBT is not known. This study compared the cost-effectiveness of specialized therapists providing ICBT support once-weekly (1WS) versus providing support once-weekly supplemented with a one-business-day response to patient emails (1W/1BD-S). We further compared the cost-effectiveness of 1W support offered by therapists employed in a specialized clinic (1WS) versus community clinics where therapists primarily deliver face-to-face therapy (1WC). Patients were randomly allocated to groups: 1WS group (n = 216), 1W/1BD-S group (n = 233), and 1WC group (n = 226). At baseline, 12, 24 and 52-week follow-up, patients completed the Treatment Inventory of Costs in Patients with Psychiatric Disorders questionnaire (TiC-P) adapted for use in Canada to assess healthcare use and productivity losses. Additionally, to assess Quality Adjusted Life Years (QALYs) gained, patients completed the EQ-5D-5L at the same time periods. We quantified uncertainties by one-way and probabilistic sensitivity analysis and reported Incremental cost-effectiveness ratios (ICER), cost-effectiveness planes and acceptability curves. Cost-effectiveness over 52 weeks was CAD 3072/QALY for 1WC, CAD 3244/QALY for 1W/1BD-S, and CAD 3528/QALY for 1WS. Our model suggests that 1WS is the best strategy since the incremental cost per QALY is below the $50,000 threshold (ICER is CAD 42,328/QALY compared to the next most effective, 1WC). 1W/1BD-S is dominated by the other strategies. The cost-effectiveness acceptability curves suggest that the 1WS group has a higher probability for cost-effectiveness (38 %) than 1W/1BD-S (30 %) and 1WC (32 %) when the willingness to pay is $50,000 per QALY. These results have important implications for health policymakers deciding on delivery of ICBT for the treatment of anxiety and/depressive disorders.

Cost and effectiveness of one session treatment (OST) for children and young people with specific phobias compared to multi-session cognitive behavioural therapy (CBT): results from a randomised controlled trial

BACKGROUND

In the UK, around 93,000 (0.8%) children and young people (CYP) are experiencing specific phobias that have a substantial impact on daily life. The current gold-standard treatment-multi-session cognitive behavioural therapy (CBT) - is effective at reducing specific phobia severity; however, CBT is time consuming, requires specialist CBT therapists, and is often at great cost and limited availability. A briefer variant of CBT called one session treatment (OST) has been found to offer similar clinical effectiveness for specific phobia as multi-session CBT. The aim of this study was to assess the cost-effectiveness of OST compared to multi-session CBT for CYP with specific phobias through the Alleviating Specific Phobias Experienced by Children Trial (ASPECT), a two-arm, pragmatic, multi-centre, non-inferiority randomised controlled trial.

METHODS

CYP aged seven to 16 years with specific phobias were recruited nationally via Health and Social Care pathways, remotely randomised to the intervention group (OST) or the control group (CBT-based therapies) and analysed (n = 267). Resource use based on NHS and personal social services perspective and quality adjusted life years (QALYs) measured by EQ-5D-Y were collected at baseline and at six-month follow-up. Incremental cost-effectiveness ratio (ICER) was calculated, and non-parametric bootstrapping was conducted to capture the uncertainty around the ICER estimates. The results were presented on a cost-effectiveness acceptability curve (CEAC). A set of sensitivity analyses (including taking a societal perspective) were conducted to assess the robustness of the primary findings.

RESULTS

After adjustment and bootstrapping, on average CYP in the OST group incurred less costs (incremental cost was -£302.96 (95% CI -£598.86 to -£28.61)) and maintained similar improvement in QALYs (QALYs gained 0.002 (95% CI - 0.004 to 0.008)). The CEAC shows that the probability of OST being cost-effective was over 95% across all the WTP thresholds. Results of a set of sensitivity analyses were consistent with the primary outcomes.

CONCLUSION

Compared to CBT, OST produced a reduction in costs and maintained similar improvement in QALYs. Results from both primary and sensitivity analyses suggested that OST was highly likely to be cost saving.

A Technology-Assisted Telephone Intervention for Work-Related Stress Management: Pilot Randomized Controlled Trial

Background

Stress management interventions combining technology with human involvement have the potential to improve the cost-effectiveness of solely human-delivered interventions, but few randomized controlled trials exist for assessing the cost-effectiveness of technology-assisted human interventions.

Objective

The aim of this study was to investigate whether a technology-assisted telephone intervention for stress management is feasible for increasing mental well-being or decreasing the time use of coaches (as an approximation of intervention cost) while maintaining participants’ adherence and satisfaction compared with traditional telephone coaching.

Methods

A 2-arm, pilot randomized controlled trial of 9 months for stress management (4-month intensive and 5-month maintenance phases) was conducted. Participants were recruited on the web through a regional occupational health care provider and randomized equally to a research (technology-assisted telephone intervention) and a control (traditional telephone intervention) group. The coaching methodology was based on habit formation, motivational interviewing, and the transtheoretical model. For the research group, technology supported both coaches and participants in identifying behavior change targets, setting the initial coaching plan, monitoring progress, and communication. The pilot outcome was intervention feasibility, measured primarily by self-assessed mental well-being (WorkOptimum index) and self-reported time use of coaches and secondarily by participants’ adherence and satisfaction.

Results

A total of 49 eligible participants were randomized to the research (n=24) and control (n=25) groups. Most participants were middle-aged (mean 46.26, SD 9.74 years) and female (47/49, 96%). Mental well-being improved significantly in both groups (WorkOptimum from “at risk” to “good” Â>0.85; P<.001), and no between-group differences were observed in the end (Â=0.56, 95% CI 0.37-0.74; P=.56). The total time use of coaches did not differ significantly between the groups (366.0 vs 343.0 minutes, Â=0.60, 95% CI 0.33-0.85; P=.48). Regarding adherence, the dropout rate was 13% (3/24) and 24% (6/25), and the mean adherence rate to coaching calls was 92% and 86% for the research and control groups, respectively; the frequency of performing coaching tasks was similar for both groups after both phases; and the diligence in performing the tasks during the intensive phase was better for the research group (5.0 vs 4.0, Â=0.58, 95% CI 0.51-0.65; P=.03), but no difference was observed during the maintenance phase. Satisfaction was higher in the research group during the intensive phase (5.0 vs 4.0, Â=0.66, 95% CI 0.58-0.73; P<.001) but not during the maintenance phase.

Conclusions

The technology-assisted telephone intervention is feasible with some modifications, as it had similar preliminary effectiveness as the traditional telephone intervention, and the participants had better satisfaction with and similar or better adherence to the intervention, but it did not reduce the time use of coaches. The technology should be improved to provide more digested information for action planning and templates for messaging.

Managing the COVID-19 pandemic in people with mental disorders: An exploratory telephone interview study in a psychiatric outpatient department

BACKGROUND

The COVID-19 pandemic and associated lockdown measures reduced well-being in the general population significantly and led to an increase in anxiety and depression symptoms, however, results on the impact on people with mental disorders are heterogeneous to date. The aim of this study was to investigate the mental health status, social support, perceived stress, and the medical care provision of people with mental disorders during the time period immediately after the first COVID-19 lockdown in spring 2020 in Germany.

METHODS

Participants were people with mental disorders currently receiving treatment in the psychiatric outpatient department of the University Hospital Leipzig, Germany. Structured telephone interviews were administered to assess depressive symptoms, self-rated medical care provision, attitudes and social and emotional aspects of the pandemic (social support, perceived stress, loneliness, resilience, and agreeableness).

RESULTS

A total of N = 106 people completed the telephone interview. The most frequent clinician-rated diagnoses were attention deficit disorder/attention deficit hyperactivity disorder (ADD/ADHD; n = 29, 27.4%) and obsessive-compulsive disorder (OCD; n = 24, 22.6%). The mean Patient Health Questionnaire-9 sum score was 10.91 (SD = 5.71) and the majority of participants (n = 56, 52.8%) reported clinically relevant depressive symptoms. A low self-rated medical care provision was significantly associated with higher depressive symptom load. In a regression analysis, higher perceived stress levels and low medical care provision significantly predicted depressive symptoms. Furthermore, 38.1% (n = 40) reported to feel relieved as a result of the restrictions and, due to previous experience in dealing with crisis, half of the participants (n = 53, 50.5%) stated they were better able to deal with the current situation than the general population.

CONCLUSIONS

This study emphasizes the importance of maintenance of medical care provision for people with mental disorders, as cancelled or postponed treatment appointments and perceived stress were associated with higher depressive symptoms. Regular treatment services showed to have a protective effect. In addition, a majority of people with mental disorders felt prepared for managing the COVID pandemic due to existing crisis management abilities. These resources should also be taken into account for further future treatment considerations.

Cost Effectiveness of Internet-Delivered Acceptance and Commitment Therapy for Patients with Severe Health Anxiety: A Randomised Controlled Trial

BACKGROUND

Health anxiety is a prevalent and debilitating disorder associated with extensive use of healthcare services and reduced quality of life (QoL). Regional variability in specialised clinics or specialist healthcare providers limits access to evidence-based treatment, which may be overcome by internet-delivered Acceptance and Commitment Therapy (iACT).

OBJECTIVE

This study investigated the cost effectiveness of iACT for severe health anxiety in adults.

METHODS

Based on a Danish randomised controlled trial (March 2016-March 2017), the economic evaluation compared costs and effects between iACT and an active control condition (iFORUM). Effectiveness was measured using self-report questionnaires. The cost analysis applied a societal perspective. Resource use and healthcare costs were extracted from the Danish National Registries. Linear regression analysis was applied using change in costs/effectiveness outcomes as the dependant variable. Time, group, and interaction between time and group were independent variables. The primary outcome was the proportion of clinically significant improvements, defined as a ≥ 25% reduction in two measures of health anxiety. The probability of cost effectiveness was presented in a cost-effectiveness acceptability curve for a range of threshold values for willingness to pay.

RESULTS

No significant differences were detected in healthcare costs between groups; however, the iACT group significantly improved in all effectiveness outcomes. The economic analysis showed that, from the healthcare perspective, iACT was associated with an incremental cost-effectiveness ratio of €33 per additional case of clinically significant improvement compared with iFORUM and that, from the societal perspective, iACT dominated iFORUM because it was more effective and less expensive.

CONCLUSIONS

We found no statistically significant differences in costs between groups; however, iACT for severe health anxiety may be cost effective, as evidenced by significant differences in effect.

Digital interventions in mental health: evidence syntheses and economic modelling

BACKGROUND

Economic evaluations provide evidence on whether or not digital interventions offer value for money, based on their costs and outcomes relative to the costs and outcomes of alternatives.

OBJECTIVES

(1) Evaluate and summarise published economic studies about digital interventions across different technologies, therapies, comparators and mental health conditions; (2) synthesise clinical evidence about digital interventions for an exemplar mental health condition; (3) construct an economic model for the same exemplar mental health condition using the previously synthesised clinical evidence; and (4) consult with stakeholders about how they understand and assess the value of digital interventions.

METHODS

We completed four work packages: (1) a systematic review and quality assessment of economic studies about digital interventions; (2) a systematic review and network meta-analysis of randomised controlled trials on digital interventions for generalised anxiety disorder; (3) an economic model and value-of-information analysis on digital interventions for generalised anxiety disorder; and (4) a series of knowledge exchange face-to-face and digital seminars with stakeholders.

RESULTS

In work package 1, we reviewed 76 economic evaluations: 11 economic models and 65 within-trial analyses. Although the results of the studies are not directly comparable because they used different methods, the overall picture suggests that digital interventions are likely to be cost-effective, compared with no intervention and non-therapeutic controls, whereas the value of digital interventions compared with face-to-face therapy or printed manuals is unclear. In work package 2, we carried out two network meta-analyses of 20 randomised controlled trials of digital interventions for generalised anxiety disorder with a total of 2350 participants. The results were used to inform our economic model, but when considered on their own they were inconclusive because of the very wide confidence intervals. In work package 3, our decision-analytic model found that digital interventions for generalised anxiety disorder were associated with lower net monetary benefit than medication and face-to-face therapy, but greater net monetary benefit than non-therapeutic controls and no intervention. Value for money was driven by clinical outcomes rather than by intervention costs, and a value-of-information analysis suggested that uncertainty in the treatment effect had the greatest value (£12.9B). In work package 4, stakeholders identified several areas of benefits and costs of digital interventions that are important to them, including safety, sustainability and reducing waiting times. Four factors may influence their decisions to use digital interventions, other than costs and outcomes: increasing patient choice, reaching underserved populations, enabling continuous care and accepting the 'inevitability of going digital'.

LIMITATIONS

There was substantial uncertainty around effect estimates of digital interventions compared with alternatives. This uncertainty was driven by the small number of studies informing most comparisons, the small samples in some of these studies and the studies' high risk of bias.

CONCLUSIONS

Digital interventions may offer good value for money as an alternative to 'doing nothing' or 'doing something non-therapeutic' (e.g. monitoring or having a general discussion), but their added value compared with medication, face-to-face therapy and printed manuals is uncertain. Clinical outcomes rather than intervention costs drive 'value for money'.

FUTURE WORK

There is a need to develop digital interventions that are more effective, rather than just cheaper, than their alternatives.

Psychological reactions of COVID-19 patients to the stress caused by the disease crisis: A descriptive phenomenological study

PURPOSE

This study was conducted to explain the psychological reactions of COVID-19 patients to the stress caused by the disease crisis from the perspective of the survivors.

DESIGN AND METHODS

A phenomenological approach was adopted to the qualitative study of 14 COVID-19 survivors selected through purposive sampling.

FINDINGS

Two themes extracted as the psychological reactions of the patients to the COVID-19-induced stress included "self-moderating effect of stress" and "psychological maladaptation."

PRACTICE IMPLICATIONS

The present findings appear effective in laying the foundations for performing interventions to improve constructive psychological reactions such as using self-moderating mechanisms of the COVID-19-induced stress and reducing or eliminating maladaptive psychological reactions such as depression, anger, self-blaming, and regret.

Economic Evaluations of Internet-Based Psychological Interventions for Anxiety Disorders and Depression: A Systematic Review

BACKGROUND

Internet-based interventions show clinical effectiveness for treating anxiety disorders and depression and could make mental healthcare more affordable.

METHODS

We searched databases including PubMed; EMBASE; Cochrane Central; PsychINFO; CINAHL; EconLit; and Web of Science from January 1, 2000 to August 21, 2020. Inclusion criteria were: 1) pertained to the treatment or prevention of anxiety disorders or depression; 2) evaluated the use of an internet-delivered psychological intervention; 3) recruited participants; and 4) reported costs or cost-effectiveness.

RESULTS

Of the 6,069 articles identified, 33 targeted anxiety (N=13) and depression (n=20) and met final inclusion criteria. All studies were from high-income countries. The control conditions and cost components included were heterogeneous. Only eight studies reported costs of developing the intervention. Of 27 studies that made a conclusion about cost-effectiveness, 81% of interventions were cost-effective. The quality of studies included was high based on a quality assessment checklist of economic evaluations, although many studies did not include definitions of cost components or differentiate between patient-side and system-level costs.

LIMITATIONS

Studies varied in methodology, making conclusions about cost-effectiveness difficult. The generalizability of these results is unclear as studies were clustered in a small number of high-income countries and costs vary over time and between regions.

CONCLUSIONS

Internet-delivered interventions appeared to be cost-effective although control conditions and cost component reporting were variable. We propose a checklist of cost components for future cost analyses to better compare intervention costs. More research is needed to describe development costs, cost-effectiveness in low-resource settings, and cost-effectiveness of newer technologies.

Cyberchondria: conceptual relation with health anxiety, assessment, management and prevention

There is a need to synthesize available information on the emerging construct of cyberchondria to guide evidence informed practice. With this in mind, electronic search of databases including MEDLINE via PubMed, Cochrane Library, ScienceDirect and Google scholar were carried out from inception till March 2020 to identify relevant English language peer reviewed articles related to cyberchondria. Generated abstracts were grouped according to their thematic focus and summarized. A total of 49 articles were reviewed. Articles directly evaluating cyberchondria were very few and most of the treatment evidence was extrapolated from trials on health anxiety. Cyberchondria appears to be a phenomenologically overlapping entity with, yet distinguishable from, health anxiety and there may be merit in studying the two constructs separately. Four validated self-assessment measures for cyberchondria are available in literature. Cognitive behaviour therapy (CBT) delivered either physically or through the internet (iCBT) have been found to be effective for both health anxiety and cyberchondria. Pharmacologic strategies for health anxiety have mainly involved the use of Selective Serotonin Reuptake Inhibitors, with mean effective dosages higher than for depression/anxiety. Prevention of cyberchondria needs to focus on appropriate harm reduction strategies as well as supply and demand side measures. Internet based CBT therapies hold promise for management of cyberchondria. This finding must be considered preliminary due to limited evidence. Further study is required to establish the diagnostic validity of cyberchondria.

Seeking neutral: A VR-based person-identity-matching task for attentional bias modification - A randomised controlled experiment

BACKGROUND

Attentional bias modification (ABM) aims to reduce anxiety by attenuating bias towards threatening information. The current study incorporated virtual reality (VR) technology and 3-dimensional stimuli with a person-identity-matching (PIM) task to evaluate the effects of a VR-based ABM training on attentional bias and anxiety symptoms.

METHODS

One hundred participants with elevated social anxiety were randomised to four training groups. Attentional bias was assessed at pre- and post-training, and anxiety symptoms were assessed at pre-training, post-training, 1-week follow-up, and 3-month follow-up.

RESULTS

Change in anxiety did not correlate with change in bias (r = -0.08). A repeated-measures ANOVA showed no significant difference in bias from pre- to post-ABM, or between groups. For anxiety symptoms, a linear mixed-effects model analysis revealed a significant effect of time. Participants showed reduction in anxiety score at each successive assessment (p < .001, Nagelkerke's pseudo r ² = 0.65). However, no other significant main effect or interactions were found. A clinically significant change analysis revealed that 4% of participants were classified as 'recovered' at 3-month follow-up.

CONCLUSIONS

A single session of VR-based PIM task did not change attentional bias. The significant reduction in anxiety was not specific to active training, and the majority of participants remained clinically unchanged.

Using Intervention Mapping to Develop a Digital Self-Management Program for People With Type 2 Diabetes: Tutorial on MyDESMOND

Digital health interventions (DHIs) are increasingly becoming integrated into diabetes self-management to improve behavior. Despite DHIs becoming available to people with chronic conditions, the development strategies and processes undertaken are often not well described. With theoretical frameworks available in current literature, it is vital that DHIs follow a shared language and communicate a robust development process in a comprehensive way. This paper aims to bring a unique perspective to digital development, as it describes the systematic process of developing a digital self-management program for people with type 2 diabetes, MyDESMOND. We provide a step-by-step guide, based on the intervention mapping (IM) framework to illustrate the process of adapting an existing face-to-face self-management program (diabetes education and self- management for ongoing and newly diagnosed, DESMOND) and translating it to a digital platform (MyDESMOND). Overall, this paper describes the 4 IM steps that were followed to develop MyDESMOND—step 1 to establish a planning group and a patient and public involvement group to describe the context of the intervention and program goals, step 2 to identify objectives and determinants at early design stages to maintain a focus on the strategies adopted, step 3 to generate the program components underpinned by appropriate psychological theories and models, and step 4 to develop the program content and describe the iterative process of refining the content and format of the digital program for implementation. This paper concludes with a number of key learnings collated throughout our development process, which we hope other researchers may find useful when developing DHIs for chronic conditions.

Cognitive behavioral therapy (CBT) anxiety management and reasoning bias modification in young adults with anxiety disorders: A real-world study of a therapist-assisted computerized (TACCBT) program Vs. "person-to-person" group CBT

Computerized cognitive behavioral therapy (cCBT) appears to be a therapeutic strategy that is as effective as person-to-person CBT in the treatment of adults and young people with anxiety disorders. The aim of our controlled study was to evaluate the following in young adult users affected by anxiety disorders: (1) the feasibility of our simple "prototype" of a therapist-assisted computerized cognitive behavioral therapy (TacCBT); and (2) the effectiveness of two different interventions-group CBT and TacCBT-in an "enriched" format for anxiety management and reasoning bias modification as compared to a control group. Psychopathology, global functioning, and cognitive flexibility were examined in 13 users undergoing TacCBT and compared to those receiving "person-to-person" group CBT (CBT Group, n = 25), which controlled for their psychopharmacological treatment. Users were included in the arms of our real-word study on the basis of their treatment preferences. Twelve subjects were included in a Treatment as Usual (TAU) group. Following the intervention, all groups showed a significant improvement in symptoms. Both CBT groups showed an improvement in cognitive flexibility with respect to TAU, in addition to a reduction of their reasoning overconfidence. Our preliminary results show the benefits of the TacCBT program and highlight its advantages.

Economic Evaluation of an Internet-Based Stress Management Intervention Alongside a Randomized Controlled Trial

BACKGROUND

Work-related stress is widespread among employees and associated with high costs for German society. Internet-based stress management interventions (iSMIs) are effective in reducing such stress. However, evidence for their cost-effectiveness is scant.

OBJECTIVE

The aim of this study was to assess the cost-effectiveness of a guided iSMI for employees.

METHODS

A sample of 264 employees with elevated symptoms of perceived stress (Perceived Stress Scale≥22) was assigned to either the iSMI or a waitlist control condition (WLC) with unrestricted access to treatment as usual. Participants were recruited in Germany in 2013 and followed through 2014, and data were analyzed in 2017. The iSMI consisted of 7 sessions plus 1 booster session. It was based on problem-solving therapy and emotion regulation techniques. Costs were measured from the societal perspective, including all direct and indirect medical costs. We performed a cost-effectiveness analysis and a cost-utility analysis relating costs to a symptom-free person and quality-adjusted life years (QALYs) gained, respectively. Sampling uncertainty was handled using nonparametric bootstrapping (N=5000).

RESULTS

When the society is not willing to pay anything to get an additional symptom-free person (eg, willingness-to-pay [WTP]=€0), there was a 70% probability that the intervention is more cost-effective than WLC. This probability rose to 85% and 93% when the society is willing to pay €1000 and €2000, respectively, for achieving an additional symptom-free person. The cost-utility analysis yielded a 76% probability that the intervention is more cost-effective than WLC at a conservative WTP threshold of €20,000 (US $25,800) per QALY gained.

CONCLUSIONS

Offering an iSMI to stressed employees has an acceptable likelihood of being cost-effective compared with WLC.

Internet-Delivered Cognitive Behavioural Therapy for Major Depression and Anxiety Disorders: A Health Technology Assessment

BACKGROUND

Major depression is defined as a period of depression lasting at least 2 weeks characterized by depressed mood, most of the day, nearly every day, and/or markedly diminished interest or pleasure in all, or almost all, activities. Anxiety disorders encompass a broad range of disorders in which people experience feelings of fear and excessive worry that interfere with normal day-to-day functioning.Cognitive behavioural therapy (CBT) is a form of evidence-based psychotherapy used to treat major depression and anxiety disorders. Internet-delivered CBT (iCBT) is structured, goal-oriented CBT delivered via the internet. It may be guided, in which the patient communicates with a regulated health care professional, or unguided, in which the patient is not supported by a regulated health care professional.

METHODS

We conducted a health technology assessment, which included an evaluation of clinical benefit, value for money, and patient preferences and values related to the use of iCBT for the treatment of mild to moderate major depression or anxiety disorders. We performed a systematic review of the clinical and economic literature and conducted a grey literature search. We reported Grading of Recommendations Assessment, Development, and Evaluation (GRADE) ratings if sufficient information was provided. When other quality assessment tools were used by the systematic review authors in the included studies, these were reported. We assessed the risk of bias within the included reviews. We also developed decision-analytic models to compare the costs and benefits of unguided iCBT, guided iCBT, face-to-face CBT, and usual care over 1 year using a sequential approach. We further explored the lifetime and short-term cost-effectiveness of stepped-care models, including iCBT, compared with usual care. We calculated incremental cost-effectiveness ratios (ICERs) from the perspective of the Ontario Ministry of Health and Long-Term Care and estimated the 5-year budget impact of publicly funding iCBT for mild to moderate major depression or anxiety disorders in Ontario. To contextualize the potential value of iCBT as a treatment option for major depression or anxiety disorders, we spoke with people with these conditions.

RESULTS

People who had undergone guided iCBT for mild to moderate major depression (standardized mean difference [SMD] = 0.83, 95% CI 0.59-1.07, GRADE moderate), generalized anxiety disorder (SMD = 0.84, 95% CI 0.45-1.23, GRADE low), panic disorder (small to very large effects, GRADE low), and social phobia (SMD = 0.85, 95% CI 0.66-1.05, GRADE moderate) showed a statistically significant improvement in symptoms compared with people on a waiting list. People who had undergone iCBT for panic disorder (SMD= 1.15, 95% CI: 0.94 to 1.37) and iCBT for social anxiety disorder (SMD=0.91, 95% CI: 0.74-1.07) showed a statistically significant improvement in symptoms compared with people on a waiting list. There was a statistically significant improvement in quality of life for people with generalized anxiety disorder who had undergone iCBT (SMD = 0.38, 95% CI 0.08-0.67) compared with people on a waiting list. The mean differences between people who had undergone iCBT compared with usual care at 3, 5, and 8 months were -4.3, -3.9, and -5.9, respectively. The negative mean difference at each follow-up showed an improvement in symptoms of depression for participants randomized to the iCBT group compared with usual care. People who had undergone guided iCBT showed no statistically significant improvement in symptoms of panic disorder compared with individual or group face-to-face CBT (d = 0.00, 95% CI -0.41 to 0.41, GRADE very low). Similarly, there was no statistically significant difference in symptoms of specific phobia in people who had undergone guided iCBT compared with brief therapist-led exposure (GRADE very low). There was a small statistically significant improvement in symptoms in favour of guided iCBT compared with group face-to-face CBT (d= 0.41, 95% CI 0.03-0.78, GRADE low) for social phobia. There was no statistically significant improvement in quality of life reported for people with panic disorder who had undergone iCBT compared with face-to-face CBT (SMD = -0.07, 95% CI -0.34 to 0.21).Guided iCBT was the optimal strategy in the reference case cost-utility analyses. For adults with mild to moderate major depression, guided iCBT was associated with increases in both quality-adjusted survival (0.04 quality-adjusted life-years [QALYs]) and cost ($1,257), yielding an ICER of $31,575 per QALY gained when compared with usual care. In adults with anxiety disorders, guided iCBT was also associated with increases in both quality-adjusted survival (0.03 QALYs) and cost ($1,395), yielding an ICER of $43,214 per QALY gained when compared with unguided iCBT. In this population, guided iCBT was associated with an ICER of $26,719 per QALY gained when compared with usual care. The probability of cost-effectiveness of guided iCBT for major depression and anxiety disorders, respectively, was 67% and 70% at willingness-to-pay of $100,000 per QALY gained. Guided iCBT delivered within stepped-care models appears to represent good value for money for the treatment of mild to moderate major depression and anxiety disorders.Assuming a 3% increase in access per year (from about 8,000 people in year 1 to about 32,000 people in year 5), the net budget impact of publicly funding guided iCBT for the treatment of mild to moderate major depression would range from about $10 million in year 1 to about $40 million in year 5. The corresponding net budget impact for the treatment of anxiety disorders would range from about $16 million in year 1 (about 13,000 people) to about $65 million in year 5 (about 52,000 people).People with depression or an anxiety disorder with whom we spoke reported that iCBT improves access for those who face challenges with face-to-face therapy because of costs, time, or the severity of their condition. They reported that iCBT provides better control over the pace, time, and location of therapy, as well as greater access to educational material. Some reported barriers to iCBT include the cost of therapy; the need for a computer and internet access, computer literacy, and the ability to understand complex written information. Language and disability barriers also exist. Reported limitations to iCBT include the ridigity of the program, the lack of face-to-face interactions with a therapist, technological difficulties, and the inability of an internet protocol to treat severe depression and some types of anxiety disorder.

CONCLUSIONS

Compared with waiting list, guided iCBT is effective and likely results in symptom improvement in mild to moderate major depression and social phobia. Guided iCBT may improve the symptoms of generalized anxiety disorder and panic disorder compared with waiting list. However, we are uncertain about the effectiveness of iCBT compared with individual or group face-to-face CBT. Guided iCBT represents good value for money and could be offered for the short-term treatment of adults with mild to moderate major depression or anxiety disorders. Most people with mild to moderate depression or anxiety disorders with whom we spoke felt that, despite some perceived limitations, iCBT provides greater control over the time, pace, and location of therapy. It also improves access for people who could not otherwise access therapy because of cost, time, or the nature of their health condition.

Clinical and economic outcomes of remotely delivered cognitive behaviour therapy versus treatment as usual for repeat unscheduled care users with severe health anxiety: a multicentre randomised controlled trial

BACKGROUND

It is challenging to engage repeat users of unscheduled healthcare with severe health anxiety in psychological help and high service costs are incurred. We investigated whether clinical and economic outcomes were improved by offering remote cognitive behaviour therapy (RCBT) using videoconferencing or telephone compared to treatment as usual (TAU).

METHODS

A single-blind, parallel group, multicentre randomised controlled trial was undertaken in primary and general hospital care. Participants were aged ≥18 years with ≥2 unscheduled healthcare contacts within 12 months and scored >18 on the Health Anxiety Inventory. Randomisation to RCBT or TAU was stratified by site, with allocation conveyed to a trial administrator, research assessors masked to outcome. Data were collected at baseline, 3, 6, 9 and 12 months. The primary outcome was change in HAI score from baseline to six months on an intention-to-treat basis. Secondary outcomes were generalised anxiety, depression, physical symptoms, function and overall health. Health economics analysis was conducted from a health service and societal perspective.

RESULTS

Of the 524 patients who were referred and assessed for trial eligibility, 470 were eligible and 156 (33%) were recruited; 78 were randomised to TAU and 78 to RCBT. Compared to TAU, RCBT significantly reduced health anxiety at six months, maintained to 9 and 12 months (mean change difference HAI -2.81; 95% CI -5.11 to -0.50; P = 0.017). Generalised anxiety, depression and overall health was significantly improved at 12 months, but there was no significant change in physical symptoms or function. RCBT was strictly dominant with a net monetary benefit of £3,164 per participant at a willingness to pay threshold of £30,000. No treatment-related adverse events were reported in either group.

CONCLUSIONS

RCBT may reduce health anxiety, general anxiety and depression and improve overall health, with considerable reductions in health and informal care costs in repeat users of unscheduled care with severe health anxiety who have previously been difficult to engage in psychological treatment. RCBT may be an easy-to-implement intervention to improve clinical outcome and save costs in one group of repeat users of unscheduled care.

Long-term outcome of therapist-guided internet-based cognitive behavioural therapy for body dysmorphic disorder (BDD-NET): a naturalistic 2-year follow-up after a randomised controlled trial

OBJECTIVES

Most patients with body dysmorphic disorder (BDD) do not receive evidence-based treatment. A randomised controlled trial (RCT) has found that a therapist-guided internet-based cognitive-behavioural therapy (CBT) programme for BDD (BDD-NET) can be delivered safely via the internet with significant improvements in BDD symptom severity in the short term. The purpose of this study was to evaluate if the therapeutic gains of BDD-NET are maintained 2 years after treatment.

SETTING

Academic medical centre.

PARTICIPANTS

A naturalistic 2-year follow-up study of the 88 self-referred adult outpatients with a diagnosis of BDD that had received BDD-NET within the context of the RCT.

PRIMARY AND SECONDARY OUTCOMES

The primary outcome was the BDD-Yale-Brown Obsessive-Compulsive Scale (YBOCS). Responder status was defined as a ≥30% reduction in symptoms. Remission was defined as no longer meeting Diagnostic and Statistical Manual of Mental Disorders 5th edition criteria for BDD. Secondary outcomes included measures of depression, global functioning and quality of life.

RESULTS

The efficacy of BDD-NET was sustained long- term, with further improvements observed on the BDD-YBOCS during the follow-up period. At follow-up, 69% (95% CI 57% to 80%) were classified as responders and 56% (95% CI 43% to 69%) were in remission. Gains on depressive symptoms and global functioning were also sustained but not quality of life. A majority of participants reported that the main reason for seeking help for their BDD was the possibility to access the treatment from home.

CONCLUSION

BDD-NET is an effective treatment for BDD, and the patients' gains are maintained in the long term. BDD-NET has the potential to increase access to CBT and may lower the threshold for BDD sufferers to seek help in the first place.

A web-based self-management programme for people with type 2 diabetes: the HeLP-Diabetes research programme including RCT

Background

In the UK, 6% of the UK population have diabetes mellitus, 90% of whom have type 2 diabetes mellitus (T2DM). Diabetes mellitus accounts for 10% of NHS expenditure (£14B annually). Good self-management may improve health outcomes. NHS policy is to refer all people with T2DM to structured education, on diagnosis, to improve their self-management skills, with annual reinforcement thereafter. However, uptake remains low (5.6% in 2014–15). Almost all structured education is group based, which may not suit people who work, who have family or other caring commitments or who simply do not like group-based formats. Moreover, patient needs vary with time and a single education session at diagnosis is unlikely to meet these evolving needs. A web-based programme may increase uptake.

Objectives

Our aim was to develop, evaluate and implement a web-based self-management programme for people with T2DM at any stage of their illness journey, with the goal of improving access to, and uptake of, self-management support, thereby improving health outcomes in a cost-effective manner. Specific objectives were to (1) develop an evidence-based theoretically informed programme that was acceptable to patients and health-care professionals (HCPs) and that could be readily implemented within routine NHS care, (2) determine the clinical effectiveness and cost-effectiveness of the programme compared with usual care and (3) determine how best to integrate the programme into routine care.

Design

There were five linked work packages (WPs). WP A determined patient requirements and WP B determined HCP requirements for the self-management programme. WP C developed and user-tested the Healthy Living for People with type 2 Diabetes (HeLP-Diabetes) programme. WP D was an individually randomised controlled trial in primary care with a health economic analysis. WP E used a mixed-methods and case-study design to study the potential for implementing the HeLP-Diabetes programme within routine NHS practice.

Setting

English primary care.

Participants

People with T2DM (WPs A, D and E) or HCPs caring for people with T2DM (WPs B, C and E).

Intervention

The HeLP-Diabetes programme; an evidence-based theoretically informed web-based self-management programme for people with T2DM at all stages of their illness journey, developed using participatory design principles.

Main outcome measures

WPs A and B provided data on user ‘wants and needs’, including factors that would improve the uptake and accessibility of the HeLP-Diabetes programme. The outcome for WP C was the HeLP-Diabetes programme itself. The trial (WP D) had two outcomes measures: glycated haemoglobin (HbA1c) level and diabetes mellitus-related distress, as measured with the Problem Areas in Diabetes (PAID) scale. The implementation outcomes (WP E) were the adoption and uptake at clinical commissioning group, general practice and patient levels and the identification of key barriers and facilitators.

Results

Data from WPs A and B supported our holistic approach and addressed all areas of self-management (medical, emotional and role management). HCPs voiced concerns about linkage with the electronic medical records (EMRs) and supporting patients to use the programme. The HeLP-Diabetes programme was developed and user-tested in WP C. The trial (WP D) recruited to target (n = 374), achieved follow-up rates of over 80% and the intention-to-treat analysis showed that there was an additional improvement in HbA1c levels at 12 months in the intervention group [mean difference –0.24%, 95% confidence interval (CI) –0.44% to –0.049%]. There was no difference in overall PAID score levels (mean difference –1.5 points, 95% CI –3.9 to 0.9 points). The within-trial health economic analysis found that incremental costs were lower in the intervention group than in the control group (mean difference –£111, 95% CI –£384 to £136) and the quality-adjusted life-years (QALYs) were higher (mean difference 0.02 QALYs, 95% CI 0.000 to 0.044 QALYs), meaning that the HeLP-Diabetes programme group dominated the control group. In WP E, we found that the HeLP-Diabetes programme could be successfully implemented in primary care. General practices that supported people in registering for the HeLP-Diabetes programme had better uptake and registered patients from a wider demographic than those relying on patient self-registration. Some HCPs were reluctant to do this, as they did not see it as part of their professional role.

Limitations

We were unable to link the HeLP-Diabetes programme with the EMRs or to determine the effects of the HeLP-Diabetes programme on users in the implementation study.

Conclusions

The HeLP-Diabetes programme is an effective self-management support programme that is implementable in primary care.

Future work

The HeLP-Diabetes research team will explore the following in future work: research to determine how to improve patient uptake of self-management support; develop and evaluate a structured digital educational pathway for newly diagnosed people; develop and evaluate a digital T2DM prevention programme; and the national implementation of the HeLP-Diabetes programme.

Recent Advances in the Understanding and Treatment of Health Anxiety

PURPOSE OF REVIEW

To examine the diagnosis of health anxiety, its prevalence in different settings, public health significance, treatment, and outcome.

RECENT FINDINGS

Health anxiety is similar to hypochondriasis but is characterized by fear of, rather than conviction of, illness. Lifetime prevalence rates are 6% in the population and as high as 20% in hospital out-patients, leading to greater costs to health services through unnecessary medical contacts. Its prevalence may be increasing because of excessive internet browsing (cyberchondria). Drug treatment with antidepressants has some efficacy but is not well-liked, but psychological treatments, including cognitive behavior therapy, stress management, mindfulness training, and acceptance and commitment therapy, given either individually, in groups, or over the Internet, have all proved efficacious in both the short and longer term. Untreated health anxiety leads to premature mortality. Health anxiety has become an increasing clinical and public health issue at a time when people are being formally asked to take more responsibility in monitoring their own health. More attention by health services is needed.

Cost-effectiveness and long-term follow-up of three forms of minimal-contact cognitive behaviour therapy for severe health anxiety: Results from a randomised controlled trial

Strategies to increase the availability of cognitive behaviour therapy (CBT) for severe health anxiety (SHA) are needed, and this study investigated the cost-effectiveness and long-term efficacy of three forms of minimal-contact CBT for SHA. We hypothesised that therapist-guided internet CBT (G-ICBT), unguided internet CBT (U-ICBT), and cognitive behavioural bibliotherapy (BIB-CBT) would all be more cost-effective than a waiting-list condition (WLC), as assessed over the main phase of the trial. We also hypothesised that improvements would remain stable up to one-year follow-up. Adults (N = 132) with principal SHA were randomised to 12 weeks of G-ICBT, U-ICBT, BIB-CBT, or WLC. The primary measure of cost-effectiveness was the incremental cost-effectiveness ratio, or the between-group difference in per capita costs divided by the between-group difference in proportion of participants in remission. The Health anxiety inventory (HAI) was the primary efficacy outcome. G-ICBT, U-ICBT, and BIB-CBT were more cost-effective than the WLC. Over the follow-up period, the G-ICBT and BIB-CBT groups made further improvements in health anxiety, whereas the U-ICBT group did not change. As expected, all three treatments were cost-effective with persistent long-term effects. CBT without therapist support appears to be a valuable alternative to G-ICBT for scaling up treatment for SHA.

Health anxiety: detection and treatment

Health anxiety is an important new diagnosis that is increasing in frequency because of changing attitudes towards health, particularly excessive use of health information on the internet (cyberchondria). People with abnormal health anxiety become over-diligent monitors of their health, misinterpret most somatic sensations as evidence of disease, consult medical professionals unnecessarily and frequently, and are often over-investigated. Relatively few patients with health anxiety present to psychiatrists; most are seen in primary and secondary medical care. This paper reviews the diagnosis and presenting features of health anxiety, its identification in practice and its treatment. A range of simple psychological treatments have been shown to have long-lasting benefit for the disorder but are greatly under-used.

The mediating effect of mindful non-reactivity in exposure-based cognitive behavior therapy for severe health anxiety

Exposure-based cognitive behavior therapy (CBT) has been shown to be effective in the treatment of severe health anxiety, but little is known about mediators of treatment effect. The aim of the present study was to investigate mindful non-reactivity as a putative mediator of health anxiety outcome using data from a large scale randomized controlled trial. We assessed mindful non-reactivity using the Five Facets Mindfulness Questionnaire-Non-Reactivity scale (FFMQ-NR) and health anxiety with the Short Health Anxiety Inventory (SHAI). Participants with severe health anxiety (N=158) were randomized to internet-delivered exposure-based CBT or behavioral stress management (BSM) and throughout the treatment, both the mediator and outcome were measured weekly. As previously reported, exposure-based CBT was more effective than BSM in reducing health anxiety. In the present study, latent process growth modeling showed that treatment condition had a significant effect on the FFMQ-NR growth trajectory (α-path), estimate=0.18, 95% CI [0.04, 0.32], p=.015, indicating a larger increase in mindful non-reactivity among participants receiving exposure-based CBT compared to the BSM group. The FFMQ-NR growth trajectory was significantly correlated with the SHAI trajectory (β-path estimate=-1.82, 95% CI [-2.15, -1.48], p<.001. Test of the indirect effect, i.e. the estimated mediation effect (αβ) revealed a significant cross product of -0.32, which was statistically significant different from zero based on the asymmetric confidence interval method, 95% CI [-0.59, -0.06]. We conclude that increasing mindful non-reactivity may be of importance for achieving successful treatment outcomes in exposure-based CBT for severe health anxiety.

Therapist-Supported Internet-Based Cognitive Behavior Therapy for Stress, Anxiety, and Depressive Symptoms Among Postpartum Women: A Systematic Review and Meta-Analysis

Background

A growing number of meta-analyses have supported the application of therapist-supported Internet-based cognitive behavior therapy (iCBT) for psychological disorders across different populations, but relatively few meta-analyses have concentrated on postpartum women.

Objective

This meta-analysis evaluated the efficacy of therapist-supported iCBT in improving stress, anxiety, and depressive symptoms among postpartum women.

Methods

A total of 10 electronic databases were used to search for published and unpublished trials. Cochrane Collaboration tool for assessing risk of bias was utilized to measure methodological quality. Meta-analysis was performed using the RevMan software (Review Manager version 5.3 for Windows from the Nordic Cochrane Centre, the Cochrane Collaboration, 2014). Among the 789 studies identified, 8 randomized controlled trials were selected, involving 1523 participants across 6 countries.

Results

More than half (65%) of the eligible studies had a low risk of bias with no heterogeneity. Results revealed that therapist-supported iCBT significantly improved stress (d=0.84, n=5), anxiety (d=0.36, n=6), and depressive symptoms (d=0.63, n=8) of the intervention group compared with those of the control group at post-intervention.

Conclusions

This review revealed that therapist-supported iCBT significantly improves stress, anxiety, and depressive symptoms among postpartum women with small to large effects. Future effectiveness studies should establish the essential components, format, and approach of iCBT with optimal levels of human support to maximize a long-term effect.
