The impacts of COVID-19 for people with obsessive-compulsive disorder (OCD) may be considerable. Online cognitive behavioural therapy (iCBT) programmes provide scalable access to psychological interventions, although the effectiveness of iCBT for OCD during COVID-19 has not been evaluated.

This study investigated the uptake and effectiveness of iCBT for OCD (both self- and clinician-guided courses) during the first 8 months of the pandemic in Australia (March to October 2020) and compared outcomes with the previous year.

1,343 adults (824/1343 (61.4%) female, mean age 33.54 years, SD = 12.00) commenced iCBT for OCD (1061 during the pandemic and 282 in the year before) and completed measures of OCD (Dimensional Obsessive-Compulsive Scale) and depression (Patient Health Questionaire-9) symptom severity, psychological distress (Kessler-10), and disability (WHO Disability Assessment Schedule) pre- and post-treatment.

During COVID-19, there was a 522% increase in monthly course registrations compared with the previous year, with peak uptake observed between April and June 2020 (a 1191% increase compared with April to June 2019). OCD and depression symptom severity were similar for the COVID and pre-COVID groups, although COVID-19 participants were more likely to enrol in self-guided courses (versus clinician-guided). In both pre- and during-COVID groups, the OCD iCBT course was associated with medium effect size reductions in OCD (g = 0.65–0.68) and depression symptom severity (g = 0.56–0.65), medium to large reductions in psychological distress (g = 0.77–0.83) and small reductions in disability (g = 0.35–.50).

Results demonstrate the considerable uptake of online psychological services for those experiencing symptoms of OCD during COVID-19 and highlight the scalability of effective digital mental health services.

Health anxiety is common, disabling and costly due to patients’ extensive use of health care services. Internet-delivered treatment may overcome barriers of accessibility to specialized treatment. We aimed to evaluate the efficacy of internet-delivered acceptance and commitment therapy (iACT).

A randomized, controlled trial of iACT versus an internet-delivered discussion forum (iFORUM), performed in a Danish university hospital setting. Patients self-referred and underwent video-diagnostic assessment. Eligible patients (≥18 years) with health anxiety were randomized to 12 weeks of intervention. The randomization was blinded for the assessor. The primary outcome was between-group unadjusted mean differences in health anxiety symptoms measured by the Whiteley-7 Index (WI-7, range 0–100) from baseline to 6-month follow-up (6-MFU) using intention to treat and a linear mixed model. The study is registered at clinicaltrials.gov, number NCT02735434.

A total of 151 patients self-referred, and 101 patients were randomized to iACT (n = 53) or iFORUM (n = 48). A mean difference in change over time of 19.0 points [95% confidence interval (CI) 10.8–27.2, p < 0.001] was shown on the WI-7, and a large standardized effect size of d = 0.80 (95% CI 0.38–1.23) at 6-MFU. The number needed to treat was 2.8 (95% CI 1.8–6.1, p < 0.001), and twice as many patients in iACT were no longer clinical cases (35% v. 16%; risk ratio 2.17, 95% CI 1.00–4.70, p = 0.050). Adverse events were few and insignificant.

iACT for health anxiety led to sustained effects at 6-MFU. The study contributes to the development of easily accessible treatment options and deserves wider application.

Severe health anxiety is a chronic and costly disorder if untreated. Patient self-referral may lower barriers to treatment and decrease diagnostic delay.

This study evaluated the accuracy of self-referral for severe health anxiety and compared characteristics of patients self-referred to internet-delivered treatment with patients referred by a clinician to face-to-face treatment.

Two trials in the same clinic employed different referral methods for health anxiety, namely self-referral and clinician-referral (trial registration: clinicaltrials.gov: NCT01158430 and NCT02735434). The trials were conducted at different time points but with largely comparable eligibility criteria. The accuracy of the recruitment methods was compared by looking at the number of eligible patients in the two trials. Patients completed a baseline questionnaire and subsequently underwent a diagnostic interview by experienced clinicians. Mean differences in self-report and clinical data explored between-group demographic and clinical characteristics.

In total, 101/151 (67%) self-referred patients were eligible compared with 126/254 (50%) clinician-referred patients (P = 0.001). Self-referred patients were 3.4 years older (P = 0.008) and had a somewhat higher educational level (P = 0.030). Patients who self-referred reported significantly higher levels of health anxiety, emotional distress and somatic symptoms compared with clinician-referred patients. Yet, they had less clinician-assessed comorbid anxiety disorders (P<0.001) and better physical health-related quality of life (P<0.001) suggesting a more distinct symptom profile.

Self-referral was found to be an accurate method to recruit highly relevant patients with treatment-demanding health anxiety. Thus, both self-referral and clinician-referral seem feasible and valid referral methods, but they may recruit patients with slightly different characteristics.

None.

Studies suggest that 10–15% of perinatal women experience depressive symptoms. Due to the risks, problems with detection, and barriers to treatment, effective universal preventive interventions are needed. The aim of this study was to assess the effectiveness of an automated internet intervention (‘Mamma Mia’) on perinatal depressive symptoms. Mamma Mia is tailored specifically to the perinatal phase and targets risk and protective factors for perinatal depressive symptoms.

A total of 1342 pregnant women were randomized to an intervention (‘Mamma Mia’) and control group. Data were collected at gestational week (gw) 21–25, gw37, 6 weeks after birth, and 3 and 6 months after birth. We investigated whether (1) the intervention group displayed lower levels of depressive symptoms compared with the control group, (2) the effect of Mamma Mia changed over time, (3) the effect on depressive symptoms was moderated by baseline depressive symptoms, previous depression, and parity, and (4) this moderation changed by time. Finally, we examined if the prevalence of mothers with possible depression [i.e. Edinburgh Postnatal Depression Scale (EPDS)-score ⩾10] differed between the intervention and control group.

Participants in the Mamma Mia group displayed less depressive symptoms than participants in the control group during follow-up [F(1) = 7.03, p = 0.008]. There were indications that the effect of Mamma Mia was moderated by EPDS score at baseline. The prevalence of women with EPDS-score ⩾10 was lower in the Mamma Mia group at all follow-up measurements.

The study demonstrated the effects of the automated web-based universal intervention Mamma Mia on perinatal depressive symptoms.

Previous research has demonstrated an association between low motivation to change and an unfavorable treatment outcome in patients with an eating disorder. Consequently, various studies have examined the effects of motivational enhancement therapy (MET) on motivation to change and treatment outcome in eating disorders. In each of these studies, MET was administered in a face-to-face setting. However, because of its anonymity and ease of access, the internet provides several advantages as the format for such an intervention. Therefore, the current study investigated the effects of an internet-based program (‘ESS-KIMO’) to enhance motivation to change in eating disorders.

In total, 212 females were accepted for participation and assigned randomly to the intervention condition (n = 103) or waiting-list control condition (n = 109). The intervention consisted of six online MET sessions. Before and after the intervention or waiting period respectively, participants completed the Eating Disorder Examination Questionnaire (EDE-Q), the Stages of Change Questionnaire for Eating Disorders (SOCQ-ED), the Pros and Cons of Eating Disorders Scale (P-CED), the Self-Efficacy Scale (SES), and the Rosenberg Self-Esteem Scale (RSES). A total of 125 participants completed the assessment post-treatment. Completer analyses and intent-to-treat analyses were performed.

Significant time × group interactions were found, indicating a stronger increase in motivational aspects and self-esteem, in addition to a stronger symptom reduction on some measures from pre- to post-treatment in the intervention group compared to the control group.

Internet-based approaches can be considered as useful for enhancing motivation to change in eating disorders and for yielding initial symptomatic improvement.
