Case-Based Trainings on Promoting Security in Caregiver-Child Relationships


he first Circle of Security intervention was an intensive group model that used individualized assessment of each dyad (using the Strange Situation Procedure and the Circle of Security Interview) to create a video-based treatment plan focused on shifting the attachment relationship toward security. A comprehensive overview of the protocol, including a review of the theory behind the intervention and step-by-step analysis of the treatment approach, brought to life with case studies, was published as The Circle of Security Intervention in 2014.

This initial COS intervention, which was run as a 20-week group, has been studied and you can read an overview of the data from the initial study of the COS Intensive group model and see download the other related publications on our research page. While you’re at it, check out the remarkable story of Tonier Cain--a graduate of a group conducted as part of an innovative prison-based program here. Tonier’s reflections on what Circle of Security has meant to her are powerful. We would also like to share the story of two child psychologists in Boras, Sweden who realized that many of the families they had already worked with needed additional help. They began offering COS Intensive in 2016 and, as a result, have uncovered great value in the group-based intervention they've conducted with higher-risk parents. Learn about their COS Intensive in Sweden story on our COSP in the Community page.

The Circle of Security Intervention book cover

Traditionally, the pathway for licensed clinicians interested in becoming certified to conduct this initial group model (what we now call the COS Intensive protocol) started with a 10-day in person training. Following the training, clinicians interested in becoming certified as COS Intensive providers prepared on their own for our case-based exam and, once they passed that exam, those interested were matched with a certified COS Intensive supervisor. Supervision involved completing multiple groups--a process that often took more than two years. Individual supervision was intensive but also costly.

With the advent of the Circle of Security Parenting program, a new approach to the psychoeducational portion of the COS Intensive protocol was created; video segments from the COSP program were used as part of the COS Intensive protocol. Clinicians also began using the COS Intensive protocol with individual clients, including dyads with children older than preschool age, making COS Intensive more accessible.

For an interesting case study and a review of the updates to the COS Intensive protocol, we recommend reading this paper written by Ellen Andrews and Joe Coyne.

Our team at COS-International is now creating a new pathway to becoming a certified COS Intensive provider. This pathway is depicted in the figure below and begins with becoming a Registered COSP Facilitator. Facilitators working with caregivers who have a history of trauma, mental health issues or a combination of risk factors are likely to encounter dyads for whom individualized, extended intervention is indicated. While the COS-Intensive training has been created for licensed clinicians with experience as psychotherapists, this training benefits other providers as an organizational framework to enhance their work with COSP. However, non-clinicians are not eligible to complete clinical supervision—the last leg on the pathway to becoming endorsed as COS-Intensive Provider.

Instead of a 10-day seminar, we are currently piloting a 5-day in person training that focuses on the individualized assessment at the heart of the COS Intensive protocol. Following completion of this 5-day training, video-based cases will be available on our online learning portal for review. Each clinician will be able to work independently to create treatment plans after reviewing dyadic interactions and caregiver interviews that we have securely posted online. This online case review will be self-guided, allowing those who’ve completed the COS-Intensive Assessment training the opportunity to create their own treatment plans by analyzing real cases. There will be more than 6 hours of online video review and the cost is set at $750USD. Two hour blocks of optional supervision is available for $370 per block for those providers who want to discuss their case formulations via videoconference. Supervision is the final step on the path to endorsement and will be conducted via secure sharing of video assessments gathered by the trainee and regular online meetings reviewing video of the clinician’s COS-Intensive intervention cases. Small group supervision is possible. Check back for updates on the supervision process as it becomes available.

Our goal is to continue to develop online learning opportunities for clinicians interested in becoming COS Intensive providers. Online learning is more convenient, saving significant travel costs for participant and trainer alike. We are hopeful that, when online self-directed learning is paired with online video sessions with a trainer, we will be able to offer COS Intensive training more broadly. At the same time, the development of online training that captures the art of psychotherapy is a complex endeavor. We plan to be systematic in deconstructing our 10-day training--creating high quality online offerings piece-by-piece until we are satisfied with the evolution of the COS Intensive training pathway.

COS-Intensive Assessment Training

Joe Coyne talks about the differences between COSP and COS-Intensive in this short video.

The Circle of Security Parenting program arose from an intensive, individualized psychotherapy protocol (what we now call COS-Intensive) which was among the first interventions explicitly tied to attachment research and focused on promoting security in specific caregiver-child relationships. Recently, we have begun to reshape training in the COS-Intensive intervention in order to make this training more accessible and efficient. If interested, we recommend you read more about the reshaping of the COS-Intensive training. Additionally, check out the COS Intensive in Sweden story on our COSP in the Community page to learn about two child psychologists in Sweden who have been offering COS Intensive since 2016. Currently, the central COS-Intensive training is a 5-day In Person training focusing on our manual for Individualized Attachment Assessment that is key to the COS-Intensive protocol. Below are upcoming options for providers interested in learning the backbone of the COS-Intensive protocol: how to create a treatment plan from structured, comprehensive attachment assessment. This is a case-based training that introduces providers to our Assessment manual, provides an overview of Core Sensitivities and reviews how to conduct and unpack the Strange Situation Procedure and the Circle of Security Interview.

COS-Intensive Case Review Course (Online Only)

This self-guided online course is designed for graduates of the COS-Intensive Assessment Training and gives participants a chance to review Strange Situation Procedures (SSP) and Circle of Security Interviews (COSI) from four carefully selected cases. The participant will have the chance to review the complete SSP and COSI videos from each case and then fill out a Linchpin Worksheet for each case. The Linchpin Worksheet is designed to provide a structured way to analyze the key struggle that each dyad presents. The course includes other downloadable resources alongside the Linchpin Worksheet to help each participant with case analysis.

After each participant has reviewed the case material, they'll then have the chance to re-watch the Strange Situation Procedure and Circle of Security Interviews, this time with narration by a COS-Intensive expert (Bert Powell or Joe Coyne). This will give each participant the opportunity to "see the case through the eyes of an expert" and to compare the participant's analysis of the linchpin to that of a clinical expert.

In the last section of the course, we've included brief narrated overviews of the treatment of two of the cases along with a pair of readings on assessment and treatment using the COS-Intensive protocol.
