Cognitive-behavioral therapy for hypochondriasis/health anxiety: a meta-analysis of treatment outcome and moderators

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.

TRIAL REGISTRATION

The trial was registered at ClinicalTrials.gov on 19 Nov 2014 with reference number NCT02298036.

Transdiagnostic, internet-delivered cognitive behavior therapy for depression and anxiety: Exploring impact on health anxiety

Health anxiety is associated with significant personal distress and economic cost; as such, widely available and effective treatment options are crucial. Several studies suggest that Internet-delivered cognitive behavior therapy (ICBT) programs that specifically target health anxiety are efficacious for this condition. However, no known studies have examined the impact of transdiagnostic ICBT, which emphasizes the acquisition of broad coping skills applicable to a variety of mental health concerns, on symptoms of health anxiety. The current study sought to explore changes in health anxiety symptoms by utilizing data available from a previously published study of 8-week transdiagnostic ICBT. Specifically, changes in symptoms of health anxiety in response to a transdiagnostic ICBT program that targeted broad symptoms of depression and anxiety, were examined in a subsample of individuals who endorsed elevated symptom scores on the Short Health Anxiety Inventory at pre-treatment (n = 72). Following treatment, large reductions in health anxiety symptoms (Cohen's d = 0.91; 20% improvement), depression (Cohen's d = 0.85; reduction = 38%), generalized anxiety (Cohen's d = 1.21; reduction = 42%), and disability (Cohen's d = 0.90; reduction = 35%) were reported. Furthermore, results showed that transdiagnostic ICBT was rated as acceptable to people with high health anxiety symptoms. Despite elevated pre-treatment health anxiety scores, email correspondence between clients and their therapist revealed very few mentions of health anxiety. These findings provide preliminary evidence for transdiagnostic ICBT for symptoms of health anxiety and suggest further research is warranted.

The impact of health anxiety on perceptions of personal and children's health in parents with Lynch syndrome

This study examined the differences in perceptions of one's health and one's child's health between parents with Lynch syndrome (LS) characterized with high versus low health anxiety. Twenty-one parents completed semistructured telephone interviews about their perceptions of their own health and the health of their children. Qualitative content analysis using a template coding approach examined the differences between parents with high and low health anxiety. Findings revealed that the most prevalent difference emerged on perceptions of personal health, showing individuals with high health anxiety reported more extreme worries, were more hypervigilant about physical symptoms, experienced the emotional and psychological consequences of LS as more negative and severe, and engaged in more dysfunctional coping strategies than those with low health anxiety. Unexpectedly, with regards to perceptions of their children, parents in the high and low health anxiety groups exhibited similar worries. However, high health anxiety parents reported using dysfunctional coping about their children's health more frequently than those with low health anxiety. The findings suggest that health anxiety is of clinical significance for individuals with LS. Accurately identifying and treating health anxiety among this population may be one avenue to reduce the distress experienced by LS carriers.

Digital Interventions for Mental Disorders: Key Features, Efficacy, and Potential for Artificial Intelligence Applications

Mental disorders are highly prevalent and often remain untreated. Many limitations of conventional face-to-face psychological interventions could potentially be overcome through Internet-based and mobile-based interventions (IMIs). This chapter introduces core features of IMIs, describes areas of application, presents evidence on the efficacy of IMIs as well as potential effect mechanisms, and delineates how Artificial Intelligence combined with IMIs may improve current practices in the prevention and treatment of mental disorders in adults. Meta-analyses of randomized controlled trials clearly show that therapist-guided IMIs can be highly effective for a broad range of mental health problems. Whether the effects of unguided IMIs are also clinically relevant, particularly under routine care conditions, is less clear. First studies on IMIs for the prevention of mental disorders have shown promising results. Despite limitations and challenges, IMIs are increasingly implemented into routine care worldwide. IMIs are also well suited for applications of Artificial Intelligence and Machine Learning, which provides ample opportunities to improve the identification and treatment of mental disorders. Together with methodological innovations, these approaches may also deepen our understanding of how psychological interventions work, and why. Ethical and professional restraints as well as potential contraindications of IMIs, however, should also be considered. In sum, IMIs have a high potential for improving the prevention and treatment of mental health disorders across various indications, settings, and populations. Therefore, implementing IMIs into routine care as both adjunct and alternative to face-to-face treatment is highly desirable. Technological advancements may further enhance the variability and flexibility of IMIs, and thus even further increase their impact in people's lives in the future.

Severe Illness Anxiety Treated by Integrating Inpatient Psychotherapy With Medical Care and Minimizing Reassurance

Illness anxiety disorder (IAD, formerly hypochondriasis) is characterized by preoccupation with fear of serious illness despite medical reassurance. IAD is common, debilitating, challenging to treat, and results in high healthcare utilization. Outpatient management of IAD is challenging because patients can compulsively seek reassurance from numerous providers, which interferes with learning more productive coping skills. We present the case of a woman with severe IAD who presented to the emergency room with increasing frequency over several months, despite regular outpatient medical visits and escalating psychiatric care. We made the unusual decision to hospitalize her for IAD for 1 month, in the absence of typical hospitalization criteria. This hospitalization allowed us to consolidate all medical and psychiatric care into a single provider team and train all staff and family to communicate with her in a consistent manner. We successfully treated her by integrating a general cognitive-behavioral therapy (CBT) protocol into medical care and decision-making. In response to her numerous health concerns, we minimized medical work-up, reassurance, and reactive medication changes, and instead used the concerns as opportunities to reinforce the psychotherapy. This approach allowed us to simplify her medication regimen and manage her co-morbid hypertension and vitamin deficiencies. Though inpatient hospitalization is likely infeasible in most cases of IAD, outpatient providers may create similar treatment plans based on the example of our case report, without needing highly specialized expertise. Such a plan would require a straightforward understanding of IAD psychology, which we review here, combined with readily accessible tools including a universal CBT protocol, online CBT courses, and clinical symptom scales. We discuss our approach for responding to health concerns, maintaining therapeutic alliance, integrating CBT principles into patient interactions, and managing medications. Since patients with IAD share health concerns with all providers, staff, and family, we also include our own IAD communication guide, appropriate for a general audience, that demonstrates how to respond in these conversations.

The suitability of motivational interviewing versus cognitive behavioural interventions on improving self-care in patients with heart failure: A literature review and discussion paper

BACKGROUND

Chronic heart failure remains a major public health concern due to its high prevalence and disease burden. Although self-care has been advocated as the sustainable solution, it remains inadequate. Recent studies have shown the potential of integrating structured counselling elements into traditional educational programs to enhance self-care but the optimal counselling method remains unclear.

AIM

To compare the applicability of cognitive behavioural interventions and motivational interviewing on improving self-care behaviours in patients with chronic heart failure.

METHOD

A systematic three-step search strategy was used to identify studies that incorporated cognitive behavioural interventions and/or motivational interviewing to improve heart failure self-care. Quantitative and qualitative trial studies that met the inclusion criteria were appraised using the Joanna Brigg's Institute criteria.

RESULTS

Motivational interviewing showed higher potential in improving HF self-care behaviours, but sustainability remains unclear. Cognitive behavioural interventions only showed effectiveness when applied to patients with comorbid depressive symptoms. Statistically significant results were only elucidated upon statistical adjustments and examination of behaviours individually. Potential effective components of CBI include setting up environmental reminders, addressing misconceptions and skills-training while that of MI was the communication style.

CONCLUSION

MI and CBI could be used synergistically by extracting their key effective components to strengthen the intention-behaviour link in improving HF self-care behaviours. MI could be used to enhance the intention to change by evoking ambivalence and change talk. CBI could be used to enhance problem-solving skills and set environmental reminders to strengthen the translation of intention to behaviour.

Feasibility Study of Group Cognitive Behavioral Therapy for Severe Health Anxiety

Severe health anxiety (SHA) is prevalent, often undiagnosed, persistent untreated, and costly. Meta-analyses have shown effectiveness of mostly individual cognitive behavioral therapy (CBT), whereas Group-CBT has only been studied and shown feasibility in one uncontrolled study of psychiatric outpatients also including self-referrals. We aimed to examine feasibility of Group-CBT for physician-referred psychiatric outpatients with SHA and a future randomized controlled trial (RCT). Group-CBT was conducted in two groups of seven participants. Feasibility was examined about recruitment rate, attrition, organization, and effectiveness. Effectiveness was measured by standardized self-report questionnaires: Whiteley Index-7 (WI-7) and Short Health Anxiety Inventory, and clinician rated remission and functioning from baseline to 3-month follow-up (3FU). Recruitment rate was 1.4 participant per month. Attrition showed dropout of 7%. Organization harbored only one senior therapist. Group-CBT showed effectiveness on all measures except WI-7 at 3FU; this latter explained by participants with concurrent borderline personality disorder. Group-CBT seems feasible for physician-referred psychiatric outpatients with SHA. With modifications, an RCT seems feasible.

Prompt mental health care, the Norwegian version of IAPT: clinical outcomes and predictors of change in a multicenter cohort study

BACKGROUND

Prompt mental health care (PMHC) is a Norwegian initiative, inspired by the English 'Improving Access to Psychological Therapy' (IAPT), aimed to provide low-threshold access to primary care treatment for persons with symptoms of anxiety and depression. The objectives of the present study are to describe the PMHC service, to examine changes in symptoms of anxiety and depression following treatment and to identify predictors of change, using data from the 12 first pilot sites.

METHODS

A prospective cohort design was used. All participants were asked to complete questionnaires at baseline, before each treatment session and at the end of treatment. Effect sizes (ES) for pre-post changes and recovery rates were calculated based on the Patient Health Questionnaire and the Generalized Anxiety Disorder scale. Multiple imputation (MI) was used in order to handle missing data. We examined predictors through latent difference score models and reported the contribution of each predictor level in terms of ES.

RESULTS

In total, N = 2512 clients received treatment at PMHC between October 2014 and December 2016, whereof 61% consented to participate. The changes from pre- to post-treatment were large for symptoms of both depression (ES = 1.1) and anxiety (ES = 1.0), with an MI-based reliable recovery rate of 58%. The reliable recovery rate comparable to IAPT based on last-observation-carried-forward was 48%. The strongest predictors for less improvement were having immigrant background (ES change depression - 0.27, ES change anxiety - 0.26), being out of work at baseline (ES change depression - 0.18, ES change anxiety - 0.35), taking antidepressants (ES change anxiety - 0.36) and reporting bullying as cause of problems (ES change depression - 0.29). Taking sleep medication did on the other hand predict more improvement (ES change depression 0.23, ES change anxiety 0.45).

CONCLUSIONS

Results in terms of clinical outcomes were promising, compared to both the IAPT pilots and other benchmark samples. Though all groups of clients showed substantial improvements, having immigrant background, being out of work, taking antidepressant medication and reporting bullying as cause stood out as predictors of poorer treatment response. Altogether, PMHC was successfully implemented in Norway. Areas for improvement of the service are discussed.

How do illness-anxious individuals process health-threatening information? A systematic review of evidence for the cognitive-behavioral model

According to the cognitive-behavioral model, illness anxiety is developed and maintained through biased processing of health-threatening information and maladaptive responses to such information.

OBJECTIVE

This study is a systematic review of research that attempted to validate central tenets of the cognitive-behavioral model regarding etiological and maintenance mechanisms in illness anxiety.

METHODS

Sixty-two studies, including correlational and experimental designs, were identified through a systematic search of databases and were evaluated for their quality.

RESULTS

Outcomes were synthesized following a qualitative thematic approach under categories of theoretically driven mechanisms derived from the cognitive-behavioral model: attention, memory and interpretation biases, perceived awareness and inaccuracy in perception of somatic sensations, negativity bias, emotion dysregulation, and behavioral avoidance.

CONCLUSIONS

Findings partly support the cognitive-behavioral model, but several of its hypothetical mechanisms only receive weak support due to the scarcity of relevant studies. Directions for future research are suggested based on identified gaps in the existing literature.

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.

Cognitive-behaviour therapy for health anxiety in medical patients (CHAMP): a randomised controlled trial with outcomes to 5 years

BACKGROUND

Health anxiety is an under-recognised but frequent cause of distress that is potentially treatable, but there are few studies in secondary care.

OBJECTIVE

To determine the clinical effectiveness and cost-effectiveness of a modified form of cognitive-behaviour therapy (CBT) for health anxiety (CBT-HA) compared with standard care in medical outpatients.

DESIGN

Randomised controlled trial.

SETTING

Five general hospitals in London, Middlesex and Nottinghamshire.

PARTICIPANTS

A total of 444 patients aged 16-75 years seen in cardiology, endocrinology, gastroenterology, neurology and respiratory medicine clinics who scored ≥ 20 points on the Health Anxiety Inventory (HAI) and satisfied diagnostic requirements for hypochondriasis. Those with current psychiatric disorders were excluded, but those with concurrent medical illnesses were not.

INTERVENTIONS

Cognitive-behaviour therapy for health anxiety - between 4 and 10 1-hour sessions of CBT-HA from a health professional or psychologist trained in the treatment. Standard care was normal practice in primary and secondary care.

MAIN OUTCOME MEASURES

Primary - researchers masked to allocation assessed patients at baseline, 3, 6, 12, 24 months and 5 years. The primary outcome was change in the HAI score between baseline and 12 months. Main secondary outcomes - costs of care in the two groups after 24 and 60 months, change in health anxiety (HAI), generalised anxiety and depression [Hospital Anxiety and Depression Scale (HADS)] scores, social functioning using the Social Functioning Questionnaire and quality of life using the EuroQol-5 Dimensions (EQ-5D), at 6, 12, 24 and 60 months, and deaths over 5 years.

RESULTS

Of the 28,991 patients screened over 21 months, 5769 had HAI scores of ≥ 20 points. Improvement in HAI scores at 3 months was significantly greater in the CBT-HA group (mean number of sessions = 6) than in the standard care, and this was maintained over the 5-year period (overall p < 0.0001), with no loss of efficacy between 2 and 5 years. Differences in the generalised anxiety (p = 0.0018) and depression scores (p = 0.0065) on the HADS were similar in both groups over the 5-year period. Gastroenterology and cardiology patients showed the greatest CBT gains. The outcomes for nurses were superior to those of other therapists. Deaths (n = 24) were similar in both groups; those in standard care died earlier than those in CBT-HA. Patients with mild personality disturbance and higher dependence levels had the best outcome with CBT-HA. Total costs were similar in both groups over the 5-year period (£12,590.58 for CBT-HA; £13,334.94 for standard care). CBT-HA was not cost-effective in terms of quality-adjusted life-years, as measured using the EQ-5D, but was cost-effective in terms of HAI outcomes, and offset the cost of treatment.

LIMITATIONS

Many eligible patients were not randomised and the population treated may not be representative.

CONCLUSIONS

CBT-HA is a highly effective treatment for pathological health anxiety with lasting benefit over 5 years. It also improves generalised anxiety and depressive symptoms more than standard care. The presence of personality abnormality is not a bar to successful outcome. CBT-HA may also be cost-effective, but the high costs of concurrent medical illnesses obscure potential savings. This treatment deserves further research in medical settings.

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.

Treatment acceptability and preferences for managing severe health anxiety: Perceptions of internet-delivered cognitive behaviour therapy among primary care patients

BACKGROUND & OBJECTIVES

While cognitive behaviour therapy (CBT) is an established treatment for health anxiety, there are barriers to service access. Internet-delivered cognitive behaviour therapy (ICBT) has demonstrated effectiveness and has the potential to improve access to treatment. Nevertheless, it is unknown how patients perceive ICBT relative to other interventions for health anxiety and what factors predict ICBT acceptability. This study investigated these questions.

METHODS

Primary care patients (N = 116) who reported elevated levels of health anxiety were presented three treatment vignettes that each described a different protocol for health anxiety (i.e., medication, CBT, ICBT). Acceptability and credibility of the treatments were assessed following the presentation of each vignette. Participants then ranked the three treatments and provided a rational for their preferences.

RESULTS

The treatments were similarly rated as moderately acceptable. Relative to medication and ICBT, CBT was perceived as the most credible treatment for health anxiety. The highest preference ranks were for CBT and medication. Regression analyses indicated that lower computer anxiety, past medication use, and lower ratings of negative cognitions about difficulty coping with an illness significantly predicted greater ICBT acceptability.

LIMITATIONS

Health anxiety was not assessed with a diagnostic interview. Primary care patients were recruited through a Qualtrics panel. Patients did not have direct experience with treatment but learned about treatment options through vignettes.

CONCLUSIONS

Medication and CBT are preferred over ICBT. If ICBT is to increase treatment access, methods of improving perceptions of this treatment option are needed.

Core Mechanisms of Cognitive Behavioral Therapy for Anxiety and Depression: A Review

This article reviews the extant literature on mediators of change in cognitive behavioral therapy (CBT) for anxiety and depression. The authors briefly discuss the efficacy of CBT for anxiety and depression and methods of mediation analysis and detection. Then the authors discuss fear extinction in anxiety treatment and cognitive change in depression treatment.

Assessing the Efficacy of Mobile Health Apps Using the Basic Principles of Cognitive Behavioral Therapy: Systematic Review

BACKGROUND

Cognitive behavioral therapy (CBT) in its basic principle has developed itself as a stand-alone, substantial method of therapy. With effective application in therapy for a range of mental health issues, the spread of CBT methods to Web-based therapy sources is evident. The development of mobile phone apps using CBT principles is increasing within the research area. Despite the move to Web-based methods of therapy, it is argued that these methods lack the same efficacy of face-to-face therapy sessions.

OBJECTIVE

The aim of this review was to assess extent research findings with regard to the effectiveness of CBT-related mobile health (mHealth) apps. By assessing only studies employing a randomized controlled trial design, the review aimed to determine app efficacy within the highly regarded method of investigation.

METHODS

A comprehensive literature search was conducted across several databases. Search results were filtered, and results were subject to strict inclusion and exclusion criteria because of the nature of the review. Where possible, analysis of effect size was calculated and results reported.

RESULTS

A total of 8 studies investigating the effectiveness of mHealth CBT-related apps across a range of mental health issues were reviewed. Three studies used the app against a control group, and 5 studies used the app intervention against another form of treatment or intervention. A range of effect sizes were seen across all included studies (d=-0.13 to 1.83; 0.03-1.44), with the largest effects often being seen when comparing the data from pre- to posttest for the app engaged group.

CONCLUSIONS

The studies reviewed support the use of mHealth apps containing CBT principles for a range of mental health issues. However, the effectiveness over longer time periods should be assessed. Researchers and professionals should seek to collaborate effectively when creating new apps to enhance their effectiveness as a treatment for the general public.

DSM-5 illness anxiety disorder and somatic symptom disorder: Comorbidity, correlates, and overlap with DSM-IV hypochondriasis

OBJECTIVE

To investigate the reliability, validity and utility of DSM-5 illness anxiety disorder (IAD) and somatic symptom disorder (SSD), and explore their overlap with DSM-IV Hypochondriasis in a health anxious sample.

METHODS

Treatment-seeking patients with health anxiety (N=118) completed structured diagnostic interviews to assess DSM-IV Hypochondriasis, DSM-5 IAD, SSD, and comorbid mental disorders, and completed self-report measures of health anxiety, comorbid symptoms, cognitions and behaviours, and service utilization.

RESULTS

IAD and SSD were more reliable diagnoses than Hypochondriasis (kappa estimates: IAD: 0.80, SSD: 0.92, Hypochondriasis: 0.60). 45% of patients were diagnosed with SSD, 47% with IAD, and 8% with comorbid IAD/SSD. Most patients with IAD fluctuated between seeking and avoiding care (61%), whereas care-seeking (25%) and care-avoidant subtypes were less common (14%). Half the sample met criteria for DSM-IV Hypochondriasis; of those, 56% met criteria for SSD criteria, 36% for IAD, and 8% for comorbid IAD/SSD. Compared to IAD, SSD was characterized by more severe health anxiety, somatic symptoms, depression, and higher health service use, and higher rates of major depressive disorder, panic disorder and agoraphobia.

CONCLUSIONS

DSM-5 IAD and SSD classifications reliably detect more cases of clinically significant health anxiety than DSM-IV Hypochondriasis. The differences between IAD and SSD appear to be due to severity. Future research should explore the generalizability of these findings to other samples, and whether diagnostic status predicts treatment response and long-term outcome.

Multidimensional Inventory of Hypochondriacal Traits: An Examination of a Bifactor Model and Measurement Invariance Between Those With and Without a Self-Reported Medical Condition

The Multidimensional Inventory of Hypochondriacal Traits (MIHT) is a self-report measure that assesses four interrelated domains of health anxiety (i.e., Cognitive, Behavioral, Perceptual, Affective). Prior research has supported a correlated four-factor model, as well as a hierarchical model, in which each of the four factors load onto the higher order health anxiety construct. However, a bifactor modeling approach has yet to be used to examine the factor structure of the MIHT. Results supported a bifactor model of the MIHT in three different samples (i.e., unselected based on current medical status [n = 824], and those with [n = 348] and without [n = 354] a self-reported medical condition). The MIHT appears to be strongly multidimensional, with three of the four subscales providing substantive value. Confirmatory factor analysis supported the configural and metric/scalar invariance of the bifactor model between those with and without a self-reported medical condition. Results provide support for a bifactor conceptualization of the MIHT and the invariance of that model across levels of current health status.

A Randomized Controlled Trial of Medication and Cognitive-Behavioral Therapy for Hypochondriasis

OBJECTIVE

Prior studies of hypochondriasis demonstrated benefits for pharmacotherapy and for cognitive-behavioral therapy (CBT). This study examined whether joint treatment offers additional benefit.

METHOD

Patients with DSM-IV hypochondriasis (N=195) were randomly assigned to one of four treatments-placebo, CBT, fluoxetine, or joint treatment with both fluoxetine and CBT. Evaluations assessed hypochondriasis, other psychopathology, adverse events, functional status, and quality of life. The primary analysis assessed outcome at week 24 among the intent-to-treat sample, with responders defined as having a 25% or greater improvement over baseline on both the Whiteley Index and a modified version of the Yale-Brown Obsessive Compulsive Scale for hypochondriasis (H-YBOCS-M). The Cochran-Armitage trend test assessed the hypothesized pattern of response: joint treatment > CBT or fluoxetine treatment > placebo treatment.

RESULTS

The predicted pattern of response was statistically significant, as shown by the following responder rates: joint treatment group, 47.2%; single active treatment group, 41.8%; and placebo group, 29.6%. Responder rates for each active treatment were not significantly different from the rate for placebo. Secondary analyses of the Whiteley Index as a continuous measure revealed that, compared with placebo, fluoxetine (but not CBT) was significantly more effective at week 24 in reducing hypochondriasis and had a significantly faster rate of improvement over 24 weeks. Fluoxetine also resulted in significantly less anxiety and better quality of life than placebo. Dropout rates did not differ between groups, and treatment-emergent adverse events were evenly distributed.

CONCLUSIONS

This study supports the safety, tolerance, and efficacy of fluoxetine for hypochondriasis. Joint treatment provided a small incremental benefit. Because approximately 50% of patients did not respond to the study treatments, new or more intensive approaches are needed.

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.

Cognitive Behaviour Therapy for Health Anxiety: A Systematic Review and Meta-Analysis

Background: Health anxiety (HA), or hypochondriasis, is a psychological problem characterized by a preoccupation with the belief that one is physically unwell. A 2007 Cochrane review (Thomson and Page, 2007) found cognitive behavioural therapy (CBT) to be an effective intervention for individuals with HA. Similar findings were reported in a recent meta-analysis (Olatunji et al., 2014), which did not employ a systematic search strategy. The current review aimed to investigate the efficacy of CBT for HA, and to update the existing reviews. Method: A systematic search was conducted following Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidance, including randomized controlled trials that compared CBT with a control condition for people with HA. Five hundred and sixty-seven studies were found in the original search, of which 14 were included in the meta-analysis. Results: Meta-analysis was conducted on 21 comparisons and a large effect size for CBT compared with a control condition was found at post therapy d = 1.01 (95% confidence interval 0.77–1.25), as well as at 6- and 12-month follow-up. Conclusions: This systematic review and meta-analysis provides support for the hypothesis that CBT is an effective intervention for HA when compared with a variety of control conditions, e.g. treatment-as-usual, waiting list, medication, and other psychological therapies.

Health anxiety in obsessive compulsive disorder and obsessive compulsive symptoms in severe health anxiety: An investigation of symptom profiles

Severe health anxiety (SHA) shares features with obsessive-compulsive disorder (OCD) and in recent years there has been a debate as to whether the two disorders may represent two facets of the same condition. Few studies have however investigated the overlap and differences in symptom profiles between the disorders. The primary aim of the present study was to investigate these aspects using one sample of participants with a principal diagnosis of SHA and one sample of participants with a principal OCD diagnosis. The second aim was to examine differences in improvement trajectories on measures of health anxiety and OCD symptoms in patients with SHA receiving treatment with exposure and response prevention. We compared persons participating in clinical trials with a principal diagnosis of SHA (N=290) to persons with a principal diagnosis of OCD (n=95) on measures of health anxiety, OCD symptoms, and depressive symptoms. A subsample of SHA participants (n=99) received exposure and response prevention (ERP) for SHA over 12 weeks and was assessed at baseline and post-treatment. The results showed large and significant differences between SHA and OCD patients on measures of health anxiety (ds=2.99-3.09) and OCD symptoms (ds=1.64-2.14), while they had equivalent levels of depressive symptoms (d=0.19, 95% CI [-0.04, 0.43]). In the SHA sample 7.6% had comorbid OCD, and in the OCD sample 9.5% had SHA. For participants with a principal diagnosis of SHA, ERP led to large reductions of health anxiety, but effects on OCD symptoms were small to moderate. Among participants with comorbid OCD, effect sizes were large on measures of health anxiety and moderate to large on OCD measures. We conclude that SHA and OCD are separate psychiatric disorders with limited overlap in symptom profiles.

Pilot trial of a therapist-supported internet-delivered cognitive behavioural therapy program for health anxiety

Cognitive behavioural therapy (CBT) is an effective treatment for health anxiety, but more research is needed to evaluate accessible, low cost ways of delivering CBT. Internet CBT may be effective, but there are no iCBT programs available outside of Sweden. We developed the first English-language clinician-guided iCBT program for health anxiety and conducted an open pilot trial (n = 16) to examine its acceptability, and impact on health anxiety and comorbidity, disability, and the cognitive and behavioural factors thought to maintain the disorder (e.g., catastrophising, hypervigilance). 13/16 participants completed the program (81% adherence). We found large and significant reductions in health anxiety, depression, distress, anxiety and disability (g's > 1.0), dysfunctional cognitions, behaviours and body vigilance between pre- and post-treatment, which were maintained at 3-month follow-up. The results provide preliminary support for the use of iCBT for health anxiety. Randomised controlled efficacy trials are now needed to evaluate this program.

Patient Characteristics and Patient Behavior as Predictors of Outcome in Cognitive Therapy and Exposure Therapy for Hypochondriasis

OBJECTIVE

Psychotherapy for hypochondriasis has greatly improved over the last decades and cognitive-behavioral treatments are most promising. However, research on predictors of treatment outcome for hypochondriasis is rare. Possible predictors of treatment outcome in cognitive therapy (CT) and exposure therapy (ET) for hypochondriasis were investigated.

METHOD

Characteristics and behaviors of 75 patients were considered as possible predictors: sociodemographic variables (sex, age, and cohabitation); psychopathology (pretreatment hypochondriacal symptoms, comorbid mental disorders, and levels of depression, anxiety, and somatic symptoms); and patient in-session interpersonal behavior.

RESULTS

Severity of pretreatment hypochondriacal symptoms, comorbid mental disorders, and patient in-session interpersonal behavior were significant predictors in multiple hierarchical regression analyses. Interactions between the predictors and the treatment (CT or ET) were not found.

CONCLUSIONS

In-session interpersonal behavior is an important predictor of outcome. Furthermore, there are no specific contraindications to treating hypochondriasis with CT or ET.

A Case Study of an Adolescent With Health Anxiety and OCD, Treated Using CBT: Single-Case Experimental Design

PROBLEM

The sparse research evidence base for adolescents with health anxiety proposes a challenge in the treatment of such mental health difficulties. Similarities are drawn between health anxiety and obsessive-compulsive disorder (OCD) in terms of their development and maintenance. The literature is reviewed and discussed in relation to the referral, assessment, formulation, cognitive behavioral intervention, and treatment outcome.

METHODS

The case of an adolescent girl (aged 15 years) who presented with significant levels of health anxiety and OCD is described. An adult cognitive behavioral model of health anxiety was adapted and integrated with evidence-based cognitive behavioral therapy (CBT) for children and adolescents with OCD. These models were used to collaboratively conceptualize the young person's presenting difficulties. A single-case experimental design was employed to assess the effectiveness of the intervention.

FINDINGS AND CONCLUSION

Routine outcome measures demonstrated the effectiveness of the OCD intervention, and the need for further research in health anxiety in young people, including the development of disorder and age-specific measures. The implications for the use of CBT to treat health anxiety for young people are discussed.

Changes in Free Symptom Attributions in Hypochondriasis after Cognitive Therapy and Exposure Therapy

BACKGROUND

Cognitive-behavioural therapy can change dysfunctional symptom attributions in patients with hypochondriasis. Past research has used forced-choice answer formats, such as questionnaires, to assess these misattributions; however, with this approach, idiosyncratic attributions cannot be assessed. Free associations are an important complement to existing approaches that assess symptom attributions.

AIMS

With this study, we contribute to the current literature by using an open-response instrument to investigate changes in freely associated attributions after exposure therapy (ET) and cognitive therapy (CT) compared with a wait list (WL).

METHOD

The current study is a re-examination of a formerly published randomized controlled trial (Weck, Neng, Richtberg, Jakob and Stangier, 2015) that investigated the effectiveness of CT and ET. Seventy-three patients with hypochondriasis were randomly assigned to CT, ET or a WL, and completed a 12-week treatment (or waiting period). Before and after the treatment or waiting period, patients completed an Attribution task in which they had to spontaneously attribute nine common bodily sensations to possible causes in an open-response format.

RESULTS

Compared with the WL, both CT and ET reduced the frequency of somatic attributions regarding severe diseases (CT: Hedges's g = 1.12; ET: Hedges's g = 1.03) and increased the frequency of normalizing attributions (CT: Hedges's g = 1.17; ET: Hedges's g = 1.24). Only CT changed the attributions regarding moderate diseases (Hedges's g = 0.69). Changes in somatic attributions regarding mild diseases and psychological attributions were not observed.

CONCLUSIONS

Both CT and ET are effective for treating freely associated misattributions in patients with hypochondriasis. This study supplements research that used a forced-choice assessment.

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

OBJECTIVES

Internet-delivered exposure-based cognitive behaviour therapy (ICBT) has been shown to be effective in the treatment of severe health anxiety. The health economic effects of the treatment have, however, been insufficiently studied and no prior study has investigated the effect of ICBT compared with an active psychological treatment. The aim of the present study was to investigate the cost effectiveness of ICBT compared with internet-delivered behavioural stress management (IBSM) for adults with severe health anxiety defined as Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM-IV) hypochondriasis. ICBT was hypothesised to be the more cost-effective treatment.

SETTING

This was a cost-effectiveness study within the context of a randomised controlled trial conducted in a primary care/university setting. Participants from all of Sweden could apply to participate.

PARTICIPANTS

Self-referred adults (N=158) with a principal diagnosis of DSM-IV hypochondriasis, of whom 151 (96%) provided baseline and post-treatment data.

INTERVENTIONS

ICBT or IBSM for 12 weeks.

PRIMARY AND SECONDARY MEASURES

The primary outcome was the Health Anxiety Inventory. The secondary outcome was the EQ-5D. Other secondary measures were used in the main outcome study but were not relevant for the present health economic analysis.

RESULTS

Both treatments led to significant reductions in gross total costs, costs of healthcare visits, direct non-medical costs and costs of domestic work cutback (p=0.000-0.035). The incremental cost-effectiveness ratio (ICER) indicated that the cost of one additional case of clinically significant improvement in ICBT compared with IBSM was $2214. The cost-utility ICER, that is, the cost of one additional quality-adjusted life year, was estimated to be $10,000.

CONCLUSIONS

ICBT is a cost-effective treatment compared with IBSM and treatment costs are offset by societal net cost reductions in a short time. A cost-benefit analysis speaks for ICBT to play an important role in increasing access to effective treatment for severe health anxiety.

Changes in negative implicit evaluations in patients of hypochondriasis after treatment with cognitive therapy or exposure therapy

BACKGROUND AND OBJECTIVES

Previous studies using modified versions of the Affect Misattribution Procedure (AMP; Payne, Cheng, Govorun, & Stewart, 2005) have revealed that there is an implicit negative evaluation bias of illness-related information in patients with hypochondriasis (HYP), which might be a maintaining feature of HYP. However, there is no evidence on whether this bias might be targeted successfully by effective treatments, such as exposure therapy (ET) or cognitive therapy (CT). This is the first study to examine the change in negative implicit evaluations in a randomized controlled trial, including individual CT and ET, compared to a wait-list control group for HYP.

METHODS

An AMP with illness, symptom and neutral primes was used in 70 patients with HYP before and after treatment (wait-list respectively).

RESULTS

There was no significant change in negative implicit affective evaluations in both CT and ET, compared to wait-list. However, comparisons between the two active treatments revealed an interaction effect, that only for CT were the affective reactions on illness-as well as symptom-related prime trials (but not neutral primes) significantly more positive at post-compared to pre-treatment. In CT but not in ET, the reduction of implicit negative evaluation bias regarding symptom-related primes was significantly related to the reduction of self-reported health anxiety.

LIMITATIONS

The small subsample sizes for CT and ET, in comparison to wait-list, prohibit the detection of smaller effects.

CONCLUSIONS

Formal cognitive restructuring is necessary for reducing implicit negative evaluation bias in HYP, but the latter is not a prerequisite for reducing health anxiety. Thus, the importance of the negative implicit evaluation bias for the maintenance of HYP remains questionable.

Mental Health Smartphone Apps: Review and Evidence-Based Recommendations for Future Developments

BACKGROUND

The number of mental health apps (MHapps) developed and now available to smartphone users has increased in recent years. MHapps and other technology-based solutions have the potential to play an important part in the future of mental health care; however, there is no single guide for the development of evidence-based MHapps. Many currently available MHapps lack features that would greatly improve their functionality, or include features that are not optimized. Furthermore, MHapp developers rarely conduct or publish trial-based experimental validation of their apps. Indeed, a previous systematic review revealed a complete lack of trial-based evidence for many of the hundreds of MHapps available.

OBJECTIVE

To guide future MHapp development, a set of clear, practical, evidence-based recommendations is presented for MHapp developers to create better, more rigorous apps.

METHODS

A literature review was conducted, scrutinizing research across diverse fields, including mental health interventions, preventative health, mobile health, and mobile app design.

RESULTS

Sixteen recommendations were formulated. Evidence for each recommendation is discussed, and guidance on how these recommendations might be integrated into the overall design of an MHapp is offered. Each recommendation is rated on the basis of the strength of associated evidence. It is important to design an MHapp using a behavioral plan and interactive framework that encourages the user to engage with the app; thus, it may not be possible to incorporate all 16 recommendations into a single MHapp.

CONCLUSIONS

Randomized controlled trials are required to validate future MHapps and the principles upon which they are designed, and to further investigate the recommendations presented in this review. Effective MHapps are required to help prevent mental health problems and to ease the burden on health systems.

Is metacognition a causal moderator of the relationship between catastrophic misinterpretation and health anxiety? A prospective study

Psychological theories have identified a range of variables contributing to health anxiety, including, dysfunctional illness beliefs, catastrophic misinterpretation, somatosensory amplification and neuroticism. More recently, metacognitive beliefs have been proposed as important in health anxiety. This study aimed to test the potential causal role of metacognitive beliefs in health anxiety. A prospective design was employed and participants (n = 105) completed a battery of questionnaire at two time points (6 months apart). Results demonstrated that cognitive, personality and metacognitive variables were bi-variate prospective correlates of health anxiety. Hierarchical regression analysis revealed that only metacognitive beliefs emerged as independent and significant prospective predictors of health anxiety. Moderation analysis demonstrated that metacognitive beliefs prospectively moderated the relationship between catastrophic misinterpretation and health anxiety. Follow-up regression analysis incorporating the interaction term (metacognition × misinterpretation) showed that the term explained additional variance in health anxiety. The results confirm that metacognition is a predictor of health anxiety and it is more substantive than misinterpretations of symptoms, somatosensory amplification, neuroticism, and illness beliefs. These results may have major implications for current cognitive models and for the treatment of health anxiety.

Acceptance and commitment group therapy (ACT-G) for health anxiety: a randomized controlled trial

BACKGROUND

Severe health anxiety is frequent and costly, yet rarely diagnosed or treated. Earlier treatment studies show problems with recruitment, dropout and recovery. In the current study, the authors aimed to test the effect of acceptance and commitment group therapy (ACT-G) compared to waitlist in patients with severe health anxiety.

METHOD

During March 2010 to April 2012, 126 consecutively referred patients meeting research criteria for severe health anxiety were block-randomized (1:1) to ACT-G or a 10 months' waitlist (Clinicaltrials.gov, no. NCT01158430). Patients allocated to ACT-G were treated in seven groups of nine patients between December 2010 and October 2012 and received nine weekly 3-h group sessions and a booster session consisting of ACT techniques. The primary outcome was decided a priori as the mean change in self-reported illness worry on the Whiteley-7 Index (WI) from baseline to 10 months' follow-up. Secondary outcomes were improvement in emotional distress and health-related quality of life at 10 months' follow-up.

RESULTS

Intention-to-treat analysis showed a statistically significant mean difference of 20.5 points [95% confidence interval (CI) 11.7-29.4, p < 0.001] on the WI between the groups at 10 months, and the between-group effect sizes were large (Cohen's d = 0.89, 95% CI 0.50-1.29). The number needed to treat was 2.4 (95% CI 1.4-3.4, p < 0.001). Diagnosis and treatment were well accepted by the patients.

CONCLUSIONS

ACT-G seems feasible, acceptable and effective in treating severe health anxiety.

Protocol investigating the clinical outcomes and cost-effectiveness of cognitive-behavioural therapy delivered remotely for unscheduled care users with health anxiety: randomised controlled trial

BACKGROUND

Health anxiety and medically unexplained symptoms cost the National Health Service (NHS) an estimated £3 billion per year in unnecessary costs with little evidence of patient benefit. Effective treatment is rarely taken up due to issues such as stigma or previous negative experiences with mental health services. An approach to overcome this might be to offer remotely delivered psychological therapy, which can be just as effective as face-to-face therapy and may be more accessible and suitable.

AIMS

To investigate the clinical outcomes and cost-effectiveness of remotely delivered cognitive-behavioural therapy (CBT) to people with high health anxiety repeatedly accessing unscheduled care (trial registration: NCT02298036).

METHOD

A multicentre randomised controlled trial (RCT) will be undertaken in primary and secondary care providers of unscheduled care across the East Midlands. One hundred and forty-four eligible participants will be equally randomised to receive either remote CBT (6-12 sessions) or treatment as usual (TAU). Two doctoral research studies will investigate the barriers and facilitators to delivering the intervention and the factors contributing to the optimisation of therapeutic outcome.

RESULTS

This trial will be the first to test the clinical outcomes and cost-effectiveness of remotely delivered CBT for the treatment of high health anxiety.

CONCLUSIONS

The findings will enable an understanding as to how this intervention might fit into a wider care pathway to enhance patient experience of care.

Development and initial validation of a measure of metacognitive beliefs in health anxiety: The MCQ-HA

Metacognitive beliefs have been shown to correlate with emotional disorders and more recently have been implicated in health anxiety. Research exploring these beliefs have tended to use the Metacognition Questionnaire (MCQ), which is a general measure. To facilitate research on the metacognitive model applied to health anxiety the present study reports on the development and initial evaluation of a new specific metacognitive measure of health anxiety, the Metacognitions Questionnaire-Health Anxiety (MCQ-HA). Principal components analysis identified 14 suitable items to be explored. Subsequent exploratory factor analysis of the MCQ-HA identified three factors: "Beliefs that Thoughts can cause Illness", "Beliefs about Biased thinking", and "Beliefs that Thoughts are Uncontrollable". Confirmatory factor analysis supported the three factor model with all selected goodness-of-fit statistics equivalent to or better than recommended values. Preliminary evidence suggests good internal-consistency, incremental, convergent and discriminant validity in relation to associated measures. The MCQ-HA appears to be a potentially useful predictor of health anxiety.

Response and Remission After Cognitive and Exposure Therapy for Hypochondriasis

Cognitive behavioral therapy has demonstrated large effect sizes for the treatment of hypochondriasis. However, response and remission rates, which provide important additional information about clinically significant improvements, have seldom been reported. In the current study, rates of response and remission after cognitive therapy and exposure therapy were evaluated. The study was based on a randomized controlled trial that treated patients with hypochondriasis (N = 75). The primary outcome measure was a clinician-administered structured interview for hypochondriasis. At posttreatment, response was found for 72.0% and remission for 45.3% of the patients. At 12-month follow-up, the response rate was 68.0%, and the remission rate was 54.7%. No significant differences in the frequency of response/remission were found between the cognitive therapy and the exposure therapy groups. Patients' and therapists' perspectives of clinical improvement corresponded with remission rather than response rates. Improvement rates were compared with those of other mental disorders, and implications for the treatment of hypochondriasis were discussed.

The Alzheimer's Prevention Clinic at Weill Cornell Medical College / New York - Presbyterian Hospital: Risk Stratification and Personalized Early Intervention

In July 2013, Weill Cornell Medical College founded the first Alzheimer's Prevention Clinic (APC) in the United States, providing direct clinical care to family members of patients with Alzheimer's disease (AD) as part of the Weill Cornell Memory Disorders Program. At the APC, patients seeking to lower their AD risk undergo a comprehensive assessment, receive a personalized plan based on rapidly evolving scientific evidence, and are followed over time using validated as well as emerging clinical and research technologies. The APC approach applies the principles of pharmacogenomics, nutrigenomics and clinical precision medicine, to tailor individualized therapies for patients. Longitudinal measures currently assessed in the clinic include anthropometrics, cognition, blood biomarkers (i.e., lipid, inflammatory, metabolic, nutritional) and genetics, as well as validated, self-reported measures that enable patients to track several aspects of health-related quality of life. Patients are educated on the fundamental concepts of AD prevention via an interactive online course hosted on Alzheimer's Universe (www.AlzU.org), which also contains several activities including validated computer-based cognitive testing. The primary goal of the APC is to employ preventative measures that lower modifiable AD risk, possibly leading to a delay in onset of future symptoms. Our secondary goal is to establish a cohort of at-risk individuals who will be primed to participate in future AD prevention trials as disease-modifying agents emerge for testing at earlier stages of the AD process. The clinical services are intended to lower concern for future disease by giving patients a greater sense of control over their brain health.

Exposure therapy changes dysfunctional evaluations of somatic symptoms in patients with hypochondriasis (health anxiety). A randomized controlled trial

Dysfunctional evaluations of somatic symptoms are considered a central factor in maintaining hypochondriasis. The aim of the current study was to investigate whether exposure therapy (ET) without cognitive restructuring is sufficient to change dysfunctional evaluations of somatic symptoms. The current study was based on a randomized controlled trial and compared patients with hypochondriasis (N=73) receiving ET or cognitive therapy (CT) to a wait list (WL) control group. In both the ET and CT groups, dysfunctional symptom evaluations changed significantly compared with the WL group. No differences between the ET and CT groups emerged. The relationship between the treatment condition (active treatment vs. WL) and reductions in health anxiety was mediated by changes in somatic symptom evaluations only in a specific card sorting procedure. We conclude that addressing dysfunctional symptom evaluations is a necessary precondition for the effective treatment of hypochondriasis. However, the results indicate that ET and CT appear to change those processes to a similar degree.

Therapist competence and therapeutic alliance are important in the treatment of health anxiety (hypochondriasis)

The role of treatment delivery factors (i.e., therapist adherence, therapist competence, and therapeutic alliance) is rarely investigated in psychotherapeutic treatment for health anxiety. This study aimed to investigate the role of the assessment perspective for the evaluation of treatment delivery factors and their relevance for treatment outcome. Therapist adherence, therapist competence, and therapeutic alliance were evaluated by independent raters, therapists, patients, and supervisors in 68 treatments. Patients with severe health anxiety (hypochondriasis) were treated with cognitive therapy or exposure therapy. Treatment outcome was assessed with a standardized interview by independent diagnosticians. A multitrait-multimethod analysis revealed a large effect for the assessment perspective of therapist adherence, therapist competence, and therapeutic alliance. The rater perspective was the most important for the prediction of treatment outcome. Therapeutic alliance and therapist competence accounted for 6% of the variance of treatment outcome while therapist adherence was not associated with treatment outcome. Therapist competence was only indirectly associated with treatment outcome, mediated by therapeutic alliance. Both therapeutic alliance and therapist competence demonstrated to be important treatment delivery factors in psychotherapy for health anxiety. A stronger consideration of those processes during psychotherapy for health anxiety might be able to improve psychotherapy outcome.

The impact of comorbid personality difficulties on response to IAPT treatment for depression and anxiety

The UK's Improving Access to Psychological Therapies (IAPT) initiative provides evidence-based psychological interventions for mild to moderate common mental health problems in a primary care setting. Predictors of treatment response are unclear. This study examined the impact of personality disorder status on outcome in a large IAPT service. We hypothesised that the presence of probable personality disorder would adversely affect treatment response.

METHOD

We used a prospective cohort design to study a consecutive sample of individuals (n = 1249).

RESULTS

Higher scores on a screening measure for personality disorder were associated with poorer outcome on measures of depression, anxiety and social functioning, and reduced recovery rates at the end of treatment. These associations were not confounded by demographic status, initial symptom severity nor number of treatment sessions. The presence of personality difficulties independently predicted reduced absolute change on all outcome measures.

CONCLUSIONS

The presence of co-morbid personality difficulties adversely affects treatment outcome among individuals attending for treatment in an IAPT service. There is a need to routinely assess for the presence of personality difficulties on all individuals referred to IAPT services. This information will provide important prognostic data and could lead to the provision of more effective, personalised treatment in IAPT.

Health anxiety and hypochondriasis in the light of DSM-5

BACKGROUND

In the DSM-5, the diagnosis of hypochondriasis was replaced by two new diagnositic entities: somatic symptom disorder (SSD) and illness anxiety disorder (IAD). Both diagnoses share high health anxiety as a common criterion, but additonal somatic symptoms are only required for SSD but not IAD.

DESIGN

Our aim was to provide empirical evidence for the validity of these new diagnoses using data from a case-control study of highly health-anxious (n = 96), depressed (n = 52), and healthy (n = 52) individuals.

RESULTS

The individuals originally diagnosed as DSM-IV hypochondriasis predominantly met criteria for SSD (74%) and rarely for IAD (26%). Individuals with SSD were more impaired, had more often comorbid panic and generalized anxiety disorders, and had more medical consultations as those with IAD. Yet, no significant differences were found between SSD and IAD with regard to levels of health anxiety, other hypochondriacial characteristics, illness behavior, somatic symptom attributions, and physical concerns, whereas both groups differed significantly from clinical and healthy controls in all of these variables.

CONCLUSION

These results do not support the proposed splitting of health anxiety/hypochondriasis into two diagnoses. Further validation studies with larger samples and additional control groups are warranted to prove the validity of the new diagnoses.

Changes in Depression, Health Anxiety, and Pain Catastrophizing Between Enrollment and 1 Month After a Radius Fracture

OBJECTIVES

To test the difference in symptoms of (1) depression, (2) health anxiety, and (3) catastrophic thinking between 1 and 6 weeks after injury to the radius.

PATIENTS AND METHODS

In total, 69 adult patients with a minimally displaced radial head or distal radius fracture were prospectively enrolled. After diagnosis, we recorded demographic variables, 11-point ordinal numerical pain score, and agreement with "no pain, no gain"; Disabilities of the Arms, Shoulder, and Hand (DASH) questionnaire; Center for Epidemiologic Studies Depression Scale; the Whiteley Index; and the Pain Catastrophizing Scale. In total, 55 patients (80%) returned after 1 month to reevaluate pain, Disabilities of the Arms, Shoulder, and Hand, Center for Epidemiologic Studies Depression, Whiteley Index, and Pain Catastrophizing Scale scores.

RESULTS

Center for Epidemiologic Studies Depression scores decreased by an average of 5 ± 9 points (p < 0.001), and Pain Catastrophizing Scale scores decreased by 2 ± 6 points (p = 0.0041). In multivariable analysis, decrease in Center for Epidemiologic Studies Depression was associated with not having an additional pain condition, more days elapsed between injury and final evaluation, and stronger agreement with "no pain, no gain" (adjusted R(2) = 0.26, p = 0.0006). An increase in Whiteley scores was associated with fewer years of education (R = -0.34, p = 0.012). Changes in Pain Catastrophizing Scale scores were associated with marital status (single -1.7 ± 4.3 vs married -4.6 ± 6.0 vs separated 0.55 ± 6.2, p = 0.040).

CONCLUSIONS

Symptoms of depression and catastrophic thinking, but not health anxiety, improved during recovery after injury. If psychologic measures are used as a screening tool to predict outcome after treatment, one should account for a patient's disease phase.

Effectiveness of cognitive-behavioral group therapy for patients with hypochondriasis (health anxiety)

Cognitive behavioral therapy (CBT) has been shown to be highly effective in the treatment of health anxiety. However, little is known about the effectiveness of group CBT in the treatment of health anxiety. The current study is the largest study that has investigated the effectiveness of combined individual and group CBT for patients with the diagnosis of hypochondriasis (N=80). Therapy outcomes were evaluated by several questionnaires. Patients showed a large improvement on these primary outcome measures both post-treatment (Cohen's d=0.82-1.08) and at a 12-month follow-up (Cohen's d=1.09-1.41). Measures of general psychopathology and somatic symptoms showed significant improvements, with small to medium effect sizes. Patients with more elevated hypochondriacal characteristics at therapy intake showed a larger therapy improvement, accounting for 7-8% of the variance in therapy outcome. CBT group therapy has therefore been shown to be an appropriate and cost-effective treatment for health anxiety.

Implicit affective evaluation bias in hypochondriasis: findings from the Affect Misattribution Procedure

Cognitive theories of hypochondriasis (HYP) suggest that catastrophic misinterpretations of benign body sensations are a core feature for the maintenance of the disorder. There is tentative support from an analog sample that the interpretation of illness-related information also involves an implicit affective component. This is the first study to examine this negative affective evaluation bias implicitly in patients with HYP. An adapted version of the Affect Misattribution Procedure (AMP) with illness, symptom and neutral primes was used in 80 patients with HYP, and compared to 83 patients with an anxiety disorder (AD), as well as 90 healthy controls (CG). The HYP group showed significantly more negative affective reactions in illness prime trials, compared to both control groups, as well as more negative implicit evaluations on symptom prime trials, compared to the CG. Significant inverse relationships were observed only between the implicit evaluations of illness words and health anxiety questionnaires. Thus, an implicit negative affective evaluation bias of serious illnesses rather than symptoms is a unique feature of HYP.
