Internet-delivered Treatments for Depression and Anxiety in Primary Care (SUMMA)

Study Overview
=================
Brief Summary
-----------------
The current study is an open feasibility trial with the aim of providing a description of the factors associated with the implementation of an iCBT platform into an existing treatment framework in a primary care setting. The trial will examine the factors surrounding implementation, such as the experience of primary care practitioners and the online supporters, the recruitment process, and attitudes towards the overall implementation of the interventions. Patients presenting to the primary care setting will be screened using standard depression and anxiety measures, and where appropriate, will be referred to an iCBT intervention for either depression or anxiety, with support from trained staff. Analyses will be conducted on outcome measures to examine changes in symptom severity as patients progress through the intervention. Patient satisfaction data will also be collected to establish patient acceptability of the intervention. [Note: Recruitment is ONLY open to patients at Ohio Family Practice Center]

Detailed Description
-----------------
iCBT is the delivery of a tailored structured cognitive and behaviour therapy based programme, with support, to individuals with mild to moderate symptoms of depression and anxiety. There is now a substantial body of research evidence that supports the efficacy and effectiveness of internet-delivered cognitive behaviour therapy for depression and anxiety. Historically, a number of iCBT interventions have been used in clinical practice in IAPT services. However, they have often suffered with poor engagement and consequently poor clinical outcomes. More recent developments in the field have produced more robust technological platforms, where content is delivered through a variety of media that enhance productivity, increase engagement and produce better clinical outcomes. The SilverCloud intervention has been demonstrated to be a clinical effective evidence-based cognitive behavioural treatment option. Approximately 90% of primary care patients with depression have one or more visits to a primary care physician (PCP) over a 12-month period, whereas less than one-third see a mental health professional. It has been reported that individuals with an anxiety disorder are 3 to 5 times more likely to visit their primary care physician than those without, but their symptoms are often associated with physical causes. PCPs often do not have training in psychological therapies and therefore they do not feel competent to treat individuals presenting with depression or anxiety. Often these individuals are prescribed antidepressant or anti-anxiety medications. The use of online programs to deliver CBT to people with mental health disorders is becoming increasingly popular. Internet-delivered CBT (iCBT) consists of programs designed for the treatment of specific disorders, such as depression and anxiety, which are delivered via the internet. These programs can be clinician-guided and/or self-administered interventions. Evidence suggests that iCBT can benefit individuals with anxiety and depression when offered in a service context that offers brief support from trained staff. Such iCBT interventions are widely-used in some European countries and the recommended length of treatment is generally 6 - 8 online sessions. A robust evidence base supporting the use and effectiveness of internet-delivered treatments for depression and anxiety has been established. Outcomes have been greater for those programs offering the additional feature of human support. The current study will examine the feasibility of implementing an iCBT platform within a primary care setting. This objective can be further dismantled into several sub objectives: Is the model of implementation (screening, recruitment, and adherence to the internet-delivered intervention) feasible? Will patients experience the iCBT intervention as satisfactory within their primary care treatment? What is the feedback of the Primary Care Practitioners about the implementation of the internet-delivered intervention as part of primary care? What is the experience of the trained supporters who assist patients within the iCBT intervention? Can an internet-delivered intervention achieve improvements in depressive and anxiety symptoms for users? Can patient attitudes toward internet-delivered interventions predict treatment outcome?

Eligibility Criteria
-----------------
Inclusion criteria: At least 18 years of age, Speak English, Self-report symptoms of depression or anxiety (using PHQ-9 and GAD-7 measures). Specifically for the self-report symptoms, participants will need to have a PHQ-9 score of 5 to 19 for the depression program or a GAD-7 score of 5 to 15 for the anxiety program. Participants currently attending face-to-face therapy/counseling will be excluded. Exclusion criteria Participants who flag as a risk on the self-harm item of the PHQ-9 during routine office visit screening will not be referred to the study and will be provided treatment and/or referral services as per the clinic's standard procedure.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Patient health Questionnaire | The PHQ-9 is a self-report measure of depression that has been widely used in screening, primary care, and research. The PHQ-9 items reflect the diagnostic criteria for depression outlined by the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition - Text Revision (DSM-IV-TR) (American Psychiatric Association [APA], 2000). Summed scores range from 0-27; larger scores reflect a greater severity of depressive symptoms. The PHQ-9 discriminated well between depressed and nondepressed individuals using the clinical cut-off of total score ≥10, with good sensitivity (88.0%) and specificity (88.0%) (Kroenke et al., 2001; R. Spitzer et al., 1999). | At week 8 | 
| Generalized Anxiety Disorder | The GAD-7 (Spitzer, Krownke, Williams, & Lowe, 2006) comprises 7 items measuring symptoms and severity of GAD based on the DSM-IV diagnostic criteria for GAD. The GAD-7 has good internal consistency (.89) and good convergent validity with other anxiety scales. Higher scores indicate greater severity of symptoms. The GAD-7 is increasingly used in large-scale studies as a generic measure of changes in anxiety symptomatology, using a cut-off score of 8 (Richards & Suckling, 2009). | At week 8 | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Socio-demographic Questionnaire | Collects information on the characteristics of the sample including age, gender etc. | At baseline for screening | 
| Work and Social Adjustment | The Work and Social Adjustment (WASA; Mundt, Marks, Shear, & Greist, 2002) is a simple, reliable and valid measure of impaired functioning. It is a simple and reliable (α >.75) 5-item self-report measure that provides an experiential impact of a disorder from the patient's point of view. It looks at how the disorder impairs the patient's ability to function day to day on five dimensions: work, social life, home life, private life and close relationships. | At baseline and week 8 | 
| Satisfaction with Treatment | The Satisfaction with Treatment (SAT; Timulak & Richards, 2012) measure contains several questions that aim to assess patient satisfaction with the iCBT intervention received. The measure consists of 2 qualitative questions and several quantitative questions, centring on what the patients liked or disliked about the iCBT intervention. | At week 8 | 
| Attitudes towards Psychological Online Interventions | The Attitudes towards Psychological Online Interventions (APOI; Schroder et al., 2015) will be administered to patients at both pre and post intervention time points. The APOI is a brief inventory that assesses attitudes towards online interventions across four domains - scepticism and perception of risks, confidence in effectiveness, technologization threat and anonymity benefits. | At baseline and week 8 |
