Severe COVID anxiety among adults in the United Kingdom: cohort study and nested feasibility trial

BackgroundPeople with severe COVID anxiety have poor mental health and impaired functioning, but the course of severe COVID anxiety is unknown and the quality of evidence on the acceptability and impact of psychological interventions is low.MethodsA quantitative cohort study with a nested feasibility trial. Potential participants aged 18 and over, living in the UK with severe COVID anxiety, were recruited online and from primary care services. We examined levels of COVID anxiety in the six months after recruitment, and factors that influenced this, using linear regression. Those scoring above 20 on the short Health Anxiety Inventory were invited to participate in a feasibility trial of remotely delivered Cognitive Behavioural Therapy for Health Anxiety (CBT-HA). Exclusion criteria were recent COVID-19, current self-isolation, or current receipt of psychological treatment. Key outcomes for the feasibility trial were the level of uptake of CBT-HA and the rate of follow-up.Results204 (70.2%) of 285 people who took part in the cohort study completed the six month follow-up, for whom levels of COVID anxiety fell from 12.4 at baseline to 6.8 at six months (difference = -5.5, 95% CI = -6.0 to -4.9). Reductions in COVID anxiety were lower among older people, those living with a vulnerable person, those with lower baseline COVID anxiety, and those with higher levels of generalised anxiety and health anxiety at baseline. 36 (90%) of 40 participants enrolled in the nested feasibility trial were followed up at six months. 17 (80.9%) of 21 people in the active arm of the trial received four or more sessions of CBT-HA. We found improved mental health and social functioning among those in the active, but not the control arm of the trial (Mean difference in total score on the Work and Social Adjustment Scale between baseline and follow up, was 9.7 (95% CI = 5.8–13.6) among those in the active, and 1.0 (95% C.I. = -4.6 to 6.6) among those in the control arm of the trial.ConclusionsWhile the mental health of people with severe COVID anxiety appears to improve over time, many continue to experience high levels of anxiety and poor social functioning. Health anxiety is highly prevalent among people with severe COVID anxiety and may provide a target for psychological treatment.Trial registrationRetrospectively registered at ISRCTN14973494 on 09/09/2021.

Severe COVID-19 anxiety among adults in the UK: protocol for a cohort study and nested feasibility trial of modified cognitive–behavioural therapy for health anxiety

IntroductionSome people are so anxious about COVID-19 that it impairs their functioning. However, little is known about the course of severe COVID-19 anxiety or what can be done to help...

Influence of apparently negative personality characteristics on the long-term outcome of health anxiety: Secondary analysis of a randomized controlled trial.

It is known that personality has an influence on the outcome of mental state disorders, but detailed studies on its long-term impact are few. We examined the influence of personality status on the 8-year outcome of health anxiety and its relationship to the effects of cognitive behaviour therapy in a randomized controlled trial. This study aims to examine both the usefulness of the diagnosis of personality disorder and an additional measure of pathological dependence, in predicting the outcome of medical patients with health anxiety treated with cognitive behaviour therapy. Because the influence of personality is often shown in the long term, these assessments covered the period of 8years after randomization. An additional aim is to examine the costs of different levels of personality dysfunction in each treatment group. Personality dysfunction, using both ICD-10 and ICD-11 classifications of severity, was assessed at baseline by interview in a randomized controlled trial. Patients were also assessed for pathological dependence using the Dependent Personality Questionnaire, also scored along a severity dimension. Four hundred forty-four patients from medical clinics with pathological health anxiety were treated with a modified form of cognitive behaviour therapy for health anxiety (CBT-HA) or standard care. Total costs over follow-up were calculated from hospital data and compared by personality group. At baseline, 381 (86%) had some personality dysfunction, mainly at the lower level of personality difficulty (not formally a disorder). One hundred eighty four (41%) had a personality disorder. A similar proportion was found with regard to dependent personality. Using the ICD-10 classification, 153 patients (34.6%) had a personality disorder, with 83 (54.2%) having anxious or dependent personality disorder, 20 (13.1%) having an anankastic disorder, but also with 66 (43.1%) having mixed disorder. During initial treatment, those with personality disorder adhered more closely to CBT-HA, and after 8years, they had a significantly better outcome than those with personality difficulty and no personality disorder (p<0.002). Similar results were found in those scoring high on the Dependent Personality Questionnaire. All these differences increased over the follow-up period. Costs were similar in all groups but were somewhat higher in the CBT-HA one; this finding is hypothesised to be due to fuller hospital treatment once health anxiety is discounted. Personality disorder in people with health anxiety, particularly in those who have anxious and dependent traits, reinforces the benefits of cognitive behaviour therapy, particularly in the longer term. © 2020 The Authors Personality and Mental Health Published by John Wiley & Sons Ltd.

Fear of illness recurrence and mental health anxiety in people recovering from psychosis and common mental health problems.

ObjectivesIt is well known that mental health problems can recur even after effective treatment, leading to an understandable fear of illness recurrence (FIR) and mental health anxiety (MHA). These may themselves contribute to the process of relapse. This study aims to examine whether people recovering from psychosis have greater FIR than those recovering from common mental health problems or healthy controls. The study also hypothesized that there will be a relationship between FIR and MHA and that both these constructs will be associated with maladaptive coping behaviours. Finally, the relationship between mental defeat with FIR and psychological distress (anxiety and depression) will be examined.MethodA cross‐sectional questionnaire design was employed. Thirty‐nine participants in recovery from psychosis, eighty‐two in recovery from other mental health difficulties, and sixty‐one healthy controls aged 18–73 were recruited from NHS services and via social media. Self‐report questionnaires measured mental defeat, mental health anxiety, fear of illness recurrence, maladaptive coping behaviours, and psychological distress.ResultsThose recovering from psychosis were found to more negatively evaluate the likely consequences of relapse than those recovering from common mental health problems or healthy controls. However, the levels of FIR in common mental health problems were also significantly elevated when compared to healthy controls. There were no other differences between these groups (in terms of mental defeat, anxiety, depression, social functioning, and maladaptive coping behaviours). The hypothesized relationship between FIR and MHA was also found, and both were associated with maladaptive coping behaviours. Mental defeat was associated with FIR and psychological distress (anxiety and depression).ConclusionsThis study found that those with psychosis experienced higher FIR than those with common mental health problems. Furthermore, people defining themselves as in recovery are worried about relapse and the extent of this is linked to mental health anxiety. Given that such responses may contribute to actual relapse, it is important that these issues are better understood and interventions developed to ameliorate them.Practitioner points Following recovery, fear of relapse may be particularly high in those with experience of psychosis; it is also present in those with common mental health problemsThe importance of this observation lies in the issue that anxiety about relapse may initiate a self‐fulfilling process, with increased anxiety worsening symptoms and vice versa.Cognitive‐behavioural therapy for health anxiety may be beneficial to those experiencing high levels of mental health anxiety.Cognitions related to relapse need to be explored and addressed both in further research and, when clearly identified, may be a target during relapse‐prevention planning.

Effect of Internet vs Face-to-Face Cognitive Behavior Therapy for Health Anxiety

Health anxiety is a common and often chronic mental health problem associated with distress, substantial costs, and frequent attendance throughout the health care system. Face-to-face cognitive behavior therapy (CBT) is the criterion standard treatment, but access is limited. To test the hypothesis that internet-delivered CBT, which requires relatively little resources, is noninferior to face-to-face CBT in the treatment of health anxiety. This randomized noninferiority clinical trial with health economic analysis was based at a primary care clinic and included patients with a principal diagnosis of health anxiety who were self-referred or referred from routine care. Recruitment began in December 10, 2014, and the last treatment ended on July 23, 2017. Follow-up data were collected up to 12 months after treatment. Analysis began October 2017 and ended March 2020. Patients were randomized (1:1) to 12 weeks of internet-delivered CBT or to individual face-to-face CBT. Change in health anxiety symptoms from baseline to week 12. Analyses were conducted from intention-to-treat and per-protocol (completers only) perspectives, using the noninferiority margin of 2.25 points on the Health Anxiety Inventory, which has a theoretical range of 0 to 54. Overall, 204 patients (mean [SD] age, 39 [12] years; 143 women [70%]) contributed with 2386 data points on the Health Anxiety Inventory over the treatment period. Of 204 patients, 102 (50%) were randomized to internet-delivered CBT, and 102 (50%) were randomized to face-to-face CBT. The 1-sided 95% CI upper limits for the internet-delivered CBT vs face-to-face CBT difference in change were within the noninferiority margin in the intention-to-treat analysis (B = 0.00; upper limit: 1.98; Cohen d = 0.00; upper limit: 0.23) and per-protocol analysis (B = 0.01; upper limit: 2.17; Cohen d = 0.00; upper limit: 0.25). The between-group effect was not moderated by initial symptom level, recruitment path, or patient treatment preference. Therapists spent 10.0 minutes per patient per week in the online treatment vs 45.6 minutes for face-to-face CBT. The net societal cost was lower in the online treatment (treatment period point difference: $3854). There was no significant group difference in the number of adverse events, and no serious adverse event was reported. In this trial, internet-delivered CBT appeared to be noninferior to face-to-face CBT for health anxiety, while incurring lower net societal costs. The online treatment format has potential to increase access to evidence-based treatment for health anxiety. ClinicalTrials.gov Identifier: NCT02314065.

Prevalence and treatment of Chronic Fatigue Syndrome/Myalgic Encephalomyelitis and co-morbid severe health anxiety

Chronic Fatigue Syndrome/Myalgic Encephalomyelitis (CFS/ME) is a debilitating condition that affects 0.2–0.4% of the population. Health focussed anxiety is common across medical conditions, and may be relevant in CFS/ME. This study sought to identify the prevalence and impact of health anxiety (HA) in CFS/ME and evaluate the effectiveness of Cognitive Behavioural Therapy for HA in CFS/ME. Cross-sectional questionnaire methods and case-series design were used to achieve study aims. Analysis indicated that 41.9% of the CFS/ME clinic sample experienced threshold levels of health anxiety, which was associated with elevated symptom severity across several dimensions. Stepwise multiple regression indicated physical functioning and depression accounted for 23.8% of variance in fatigue; depression, fatigue and HA, accounted for 32.9% of variance in physical functioning. Large effect sizes and clinically significant changes were generated in the treatment study. HA is common in CFS/ME and likely to exacerbate fatigue and physical functioning. This study identifies HA as an important target for treatment, trial findings should be further replicated on a larger scale.

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

Health anxiety is an under-recognised but frequent cause of distress that is potentially treatable, but there are few studies in secondary care. 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. Randomised controlled trial. Five general hospitals in London, Middlesex and Nottinghamshire. 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. 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. 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. 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. Many eligible patients were not randomised and the population treated may not be representative. 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. Current Controlled Trials ISRCTN14565822.

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

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. 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. 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. 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.

Impact of personality status on the outcomes and cost of cognitive-behavioural therapy for health anxiety.

BackgroundHealth anxiety, hypochondriasis and personality disturbance commonly coexist. The impact of personality status was assessed in a secondary analysis of a randomised controlled trial (RCT).AimsTo test the impact of personality status using ICD-11 criteria on the clinical and cost outcomes of treatment with cognitive–behavioural therapy for health anxiety (CBT-HA) and standard care over 2 years.MethodPersonality dysfunction was assessed at baseline in 444 patients before randomisation and independent assessment of costs and outcomes made on four occasions over 2 years.ResultsIn total, 381 patients (86%) had some personality dysfunction with 184 (41%) satisfying the ICD criteria for personality disorder. Those with no personality dysfunction showed no treatment differences (P = 0.90) and worse social function with CBT-HA compared with standard care (P<0.03) whereas all other personality groups showed greater improvement with CBT-HA maintained over 2 years (P<0.001). Less benefit was shown in those with more severe personality disorder (P<0.05). Costs were less with CBT-HA except for non-significant greater differences in those with moderate or severe personality disorder.ConclusionsThe results contradict the hypothesis that personality disorder impairs response to CBT in health anxiety in both the short and medium term.

Dimensions of dependence and their influence on the outcome of cognitive behaviour therapy for health anxiety: randomized controlled trial.

The personality trait of dependence is common in health-seeking behaviour. We therefore examined its impact in a large randomized controlled trial of psychological treatment for health anxiety. To test whether dependent personality traits were positive or negative in determining the outcome of an adapted form of cognitive behaviour therapy for health anxiety (CBT-HA) over the course of 5 years and whether dependent personality dysfunction could be viewed dimensionally in a similar way to the new ICD-11 diagnostic system for general personality disorder. Dependent personality dysfunction was assessed using a self-rated questionnaire, the Dependent Personality Questionnaire, at baseline in a randomized controlled trial of 444 patients from medical clinics with pathological health anxiety treated with a modified form of CBT-HA or standard treatment in the medical clinics, with assessment on five occasions over 5 years. Dependent personality dysfunction was assessed using four severity groups. Patients with mild and moderate dependent personality disorder treated with CBT-HA showed the greatest reduction in health anxiety compared with standard care, and those with no dependent dysfunction showed the least benefit. Patients with higher dependent traits received significantly more treatment sessions (8.6) than those with low trait levels (5.4) (p < 0.01). The results suggest that patients treated with cognitive behaviour therapy for health anxiety respond better if they have moderate dependent personality. The reasons for this may be related to better adherence to psychological treatment and greater negative effects of frequent reassurance and excessive consultation in those treated in standard care.
