Objective
The rising prevalence of mental health symptoms brought on by the COVID19 pandemic led to the inception and development of EMERging Anxiety, Loneliness, Depression (EMERALD) well-being programme. EMERALD was designed to improve psychological well-being of the general population who had not previously sought mental health support. The programme incorporated a focus on lifestyle medicine and was underpinned by solution focused health coaching. The aim of the paper is to describe the programme according to the Template for Intervention Description and Replication (TIDieR) checklist to provide detailed reporting of the intervention's elements.
Methods
The TIDieR checklist was utilised to comprehensively describe the programme, including theoretical underpinnings, materials, procedures, providers, mode of delivery and tailoring of the programme. The Behaviour Change Technique Taxonomy v2 was used to identify the specific behaviour change techniques used within the solution focused health coaching framework.
Results
The programme was developed to align with the latest evidence-based literature in lifestyle medicine and solution focused coaching. The programme also offered allied health expertise, online educational modules and was tailored to the participants. The programme was delivered online through a telehealth platform.
Conclusion
The TIDieR checklist has enabled the provision of a detailed structure of the EMERALD program intervention. The behaviour change taxonomy has facilitated the outlining of specific techniques used in health coaching sessions. Both structures have operationalised the detail of the intervention for the purposes of replication and informing the literature.

Low dose oral ketamine treatment in chronic suicidality: An open-label pilot study
Published 2021
Translational Psychiatry, 11, 1, 101 - 101
Recently, low-dose ketamine has been proposed as a rapid-acting treatment option for suicidality. The majority of studies to date have utilised intravenous (IV) ketamine, however, this route of administration has limitations. On the other hand, oral ketamine can be administered in a range of settings, which is important in treating suicidality, although studies as to safety and feasibility are lacking.
n
= 32 adults (aged 22–72 years; 53% female) with chronic suicidal thoughts participated in the Oral Ketamine Trial on Suicidality (OKTOS), an open-label trial of sub-anaesthetic doses of oral ketamine over 6 weeks. Participants commenced with 0.5 mg/kg of ketamine, which was titrated to a maximum 3.0 mg/kg. Follow-up assessments occurred at 4 weeks after the final dose. The primary outcome measure was the Beck Scale for Suicide Ideation (BSS) and secondary measures included scales for suicidality and depressive symptoms, and measures of functioning and well-being. Mean BSS scores significantly reduced from a high level of suicidal ideation at the pre-ketamine (week 0) timepoint to below the clinical threshold at the post-ketamine (week 6) timepoint. The proportion of participants that achieved clinical improvement within the first 6 weeks was 69%, whereas 50% achieved a significant improvement by the follow-up (week 10) timepoint. Six weeks of oral ketamine treatment in participants with chronic suicidality led to significant reduction in suicidal ideation. The response observed in this study is consistent with IV ketamine trials, suggesting that oral administration is a feasible and tolerable alternative treatment for chronic suicidality.

Effectiveness of Group Cognitive Therapy for Social Anxiety Disorder in Routine Care
Published 2021
Behaviour Change, 38, 2, 60 - 72
Social anxiety disorder (SAD) is a prevalent chronic condition with a large demand for treatment. This community outpatient study examined the effectiveness of a group intervention version of the established one-to-one cognitive therapy derived from the Clark and Wells model for SAD. Questionnaires were completed pre-treatment and post-treatment for SAD symptoms (Social Phobia Scale, Social Interaction Anxiety Scale), depressive symptoms (BDI-II), self-focused attention, safety behaviours (Social Phobia Weekly Summary Scale and Subtle Avoidance Frequency Examination), and impaired functioning (Work and Social Adjustment Scale). From an initial sample of 159 participants, 101 completed at least seven of the nine weekly group sessions (Mage = 34.1 years, SDage = 10.8 years, 53% female). Significant improvements were demonstrated on all measures. Large effect sizes were found for social anxiety symptoms and safety behaviour use. Self-focused attention, depressive symptoms, and impaired functioning had moderate effect sizes. Effect sizes for anxiety (d = 1.00 and 1.32) and mood measures (d = 0.71) were as high, or in some cases, higher than previous group treatment studies. Results suggest group cognitive therapy for SAD based on the Clark and Wells model is effective in a clinical setting for individuals with moderate/severe and treatment-resistant social anxiety.

Recovery of functioning is integral to successful treatment outcomes in depressive illness. Optimal antidepressant treatment results in both symptomatic remission and functional recovery. Oral ketamine rapidly reduces suicidality and depression; however, reports of functional and wellbeing outcomes are lacking. This study examines participants’ social and occupational functioning and wellbeing outcomes in the Oral Ketamine Trial on Suicidality (OKTOS). Thirty adults with chronic suicidality participated in the trial over 10 weeks. Functional recovery and wellbeing were assessed using the Social and Occupational Functioning Scale (SOFAS) and World Health Organization Well-Being Index (WHO-5). Suicidality and depressive symptoms were assessed using the Beck Scale for Suicidal ideation (BSS) and Montgomery-Asberg Depression Rating Scale (MADRS). Relationships between the four treatment outcomes were analysed. Forty-three percent of participants achieved healthy function (SOFAS ≥80) and 27% reported healthy wellbeing (WHO-5 >60%) at the four-week post-treatment follow-up. Wellbeing was revealed as the data-derived treatment endpoint for the sample. Effect sizes for functioning and wellbeing outcomes were smaller than for suicidality and depression outcomes. Results suggest that reduction in depressive symptoms and suicidal ideation may be necessary but not sufficient for full resto-ration of function and wellbeing in antisuicidal and antidepressant therapy, including clinical trials.

Background: The glutamatergic modulator ketamine has been shown to result in rapid reductions in both suicidal ideation (SI) and depressive symptoms in clinical trials. There is a practical need for identification of pre-treatment predictors of ketamine response. Previous studies indicate links between treatment response and body mass index (BMI), depression symptoms and previous suicide attempts. Our aim was to explore the use of clinical and demographic factors to predict response to serial doses of oral ketamine for chronic suicidal ideation. Methods: Thirty-two participants completed the Oral Ketamine Trial on Suicidality (OKTOS). Data for the current study were drawn from pre-treatment and follow-up time-points of OKTOS. Only clinical and sociodemographic variables were included in this analysis. Data were used to create a proof of concept Bayesian network (BN) model of variables predicting prolonged response to oral ketamine, as defined by the Beck Scale for Suicide Ideation (BSS). Results: The network of potential predictors of response was evaluated using receiver operating characteristic (ROC) curve analyses. A combination of nine demographic and clinical variables predicted prolonged ketamine response, with strong contributions from BMI, Social and Occupational Functioning Assessment Scale (SOFAS), Montgomery-Asberg Depression Rating Scale (MADRS), number of suicide attempts, employment status and age. We evaluated and optimised the proposed network to increase the area under the ROC curve (AUC). The performance evaluation demonstrated that the BN predicted prolonged ketamine response with 97% accuracy, and AUC = 0.87. Conclusions: At present, validated tools to facilitate risk assessment are infrequently used in psychiatric practice. Pre-treatment assessment of individuals’ likelihood of response to oral ketamine for chronic suicidal ideation could be beneficial in making more informed decisions about likelihood of success for this treatment course.
