  • Payment in full is required at least ONE WEEK prior to the start of the training.
  • Any cancellations made within ONE WEEK of the start of the training will incur a $200 cancellation fee.
  • If you are an individual paying for yourself to attend the training, you will be required to sign an “Individual Contract” stating that you are licensing the rights to use the facilitator materials and will not give the materials to anyone.
  • If you are an individual whose agency is paying for you to attend the training, your agency will have the option to sign an “Agency Contract.” The individual and the agency will be required to sign the contract which allows the agency to hold the facilitator materials in the event that the individual leaves the agency. The agency will then have the option to send another employee to a training at a reduced fee who will use the facilitator materials held from the exiting individual. At no time can the held materials be used by any persons who have not been trained to use the materials by our Circle of Security trainers. The individual leaving the agency will have the option to purchase an individual copy of the facilitator materials and will then sign an “Individual Contract.”
  • It is your responsibility to make sure you are signing the correct contract. The Agency Contract needs to be arranged PRIOR to the training and can be downloaded from our website. If you have any questions about which contract you should be signing, please contact our office. If you do not turn in a contract at the training, you will NOT receive the DVD materials.
  • If you are registering as a small or large group, and are receiving the corresponding group rate discount, you understand and agree to the following terms and conditions:
    • Small group of 5-9 people - 10% off cost of training

An “Individual Contract” is the most typical and establishes an agreement between the attendee and Circle of Security International regarding their responsibilities as a Registered Circle of Security Parenting Facilitator, as well as being responsible for the DVD and Manuals. These contracts will be made available on the last day of the training. View the Individual Licensing Contract.

An “Individual Contract” is the most typical and establishes an agreement between the attendee and Circle of Security International regarding their responsibilities as a Registered Circle of Security Parenting Facilitator, as well as being responsible for the DVD and Manuals. These contracts will be made available on the last day of the training. View the Individual Licensing Contract.

With an “Agency Contract” both the individual and the agency will be required to sign the contract. In this case the individual still has the rights and responsibilities of being a Circle of Security Parenting Facilitator but the agency takes responsibility for the DVD and Manual. If the individual leaves the agency the agency maintains control of the materials, the agency will then have the option to send another employee to a training at a reduced fee. At no time can the held materials be used by any persons who have not been trained to use the materials by a CHP Originator or Circle of Security Parenting Contracted trainer (designated by CHP).

The individual leaving the agency will then have the option to purchase an individual copy of the facilitator materials and will then sign an “Individual Contract.”

As agency contracts need to be signed by a manager at the agency and then brought to the training by the attendee, prior arrangements need to be made.

If these arrangements are not made prior to the training we ask that the attendee sign an individual contract at the training and then we would be happy to switch it over to an agency contract at a later date.

If you will be using an Agency Contract, please contact Bill Bloom to set this up: bill@circleofsecurityinternational.com

The Parenting DVD can only be obtained after completing the Parenting DVD training. You can find out more information about the training on the Trainings page. If you are in need of a replacement DVD or manual, please contact info@circleofsecurityinternational.com for purchasing information.

Because psychologists, educators, childcare professionals, counselors, and others have found these graphics to be useful for parents and professionals in explaining the core themes of attachment behavior in young children, we want to make them readily available through this website. Please see the Resources section and read the detailed description of our conditions for using these materials.

For specific requests related to publishing Circle of Security materials, approval is given only to non-profit organizations and academic/professional publications upon review by Circle of Security International. Please email info@circleofsecurityinternational.com to receive a permission request form. Requests take approximately 4 weeks to review.

The COS is a user-friendly, visually based approach (utilizing extensive use of both graphics and video clips) to helping parents better understand the needs of their children. It is based extensively upon attachment theory (from the work of John Bowlby and Mary Ainsworth) and current affective neuroscience.

It is also a basic protocol that can be used in a variety of settings, from group sessions (20 weeks) to family therapy to home visitation. The common denominator is that all of the learning is informed around the following themes:

  • Teaching the basics of attachment theory via the Circle of Security
  • Increasing parent skills in observing parent/child interactions
  • Increasing capacity of the caregiver to recognize and sensitively respond to children’s needs
  • Supporting a process of reflective dialogue between clinician and parent to explore both strengths and areas of parent difficulties (i.e., being “Bigger, Stronger, Wiser, and Kind,” supporting exploration, and supporting attachment)
  • Introducing parent to a user-friendly way to explore defensive process

Although we would very much like to be of assistance, we simply do not have the time available for consultation at such a level. Attachment related material raises many concerns and opens many insights as it is being learned. Please consider contacting a professional in your local area.

No, unfortunately they are not taking new patients.

We do not have any affiliation with the Mary D. Ainsworth Child-Parent Attachment Clinic or their Circle of Security® trainings. Dr. Robert Marvin has co-ownership of the Circle of Security trademark for the graphic, and is part of our research history. The trainings offered by his group are different in structure and content from the Circle of Security ® protocol given by Cooper, Hoffman, and Powell. Neither training translates to the other.

This is a very important issue and we are committed to answering it directly. While there are a number of early intervention projects being developed and tested that focus on the security of attachment-caregiving relationships in high-risk parents and their infants, there are very few evidence-based programs that are focused on older toddlers and preschool children. Unfortunately, those programs for preschoolers and older children that do exist tend to take one or a few ideas from attachment theory and research, incorporate them in an oversimplified manner into another, usually incompatible, theoretical framework, and apply the resulting programs without adequately testing their effectiveness.

Specifically, these programs, some of which are known as Rebirthing, Rage Reduction, Attachment, or Holding Therapy, and as a group are often referred to as “the holding therapies,” have been published privately, in edited books, and on the Internet. The designers of these programs draw from Bowlby’s theory a focus on the importance during infancy of close bodily contact, security, and trust in the child’s attachment figure. However, these “holding therapies” tend to have taken those constructs and integrated them into intervention models based either: a) on a distorted version of the classical psychoanalytic theory of regression (Rebirthing and Rage Reduction therapies); and/or on behaviorism and principles of behavior modification designed to reduce or eliminate undesirable behaviors (Attachment and Holding therapies). Clearly, these are not really attachment theory-based interventions, and they are not appropriately evidence-based.

Characteristics of the holding therapies have led to the proliferation of interventions that, while they are administered by therapists with the best of intentions, are at worst abusive and potentially life-threatening and at best are neither based on attachment theory, nor empirically tested regarding treatment effectiveness. Unfortunately, many of these programs claim to be based on the Bowlby-Ainsworth theory of attachment, and there are literally thousands of therapists in communities around the U.S., Canada, Europe, and Australia who use them in their daily practice. In defense of these therapists, it should also be noted that until very recently there have been few if any evidence-based interventions for preschool and older children, truly developed from attachment research, available to them.

Interventions that are evidence-based and derived from attachment theory will have many differences from the holding therapies. Three that are especially pertinent to evidence-based practice are:

  1. Holding therapies tend to use a diagnostic system that is non-standardized, non-validated, and not able to differentiate among the many psychological disorders found in childhood. In contrast, attachment research-based interventions should utilize a “diagnostic” system that is based specifically on thought and behavior patterns identified through attachment theory and research, and on research in other areas of parent-child interaction and relationships. This system should be scientifically and clinically reliable and validated. It should be sufficiently limited in scope both to identify specific attachment problems, and at the same time to differentiate these problems from other childhood and relationship difficulties as well as from formal diagnostic groups such as ADHD, Oppositional Defiant Disorder, Conduct Disorder, Bi-Polar Disorder, and other disorders so often inappropriately associated in clinical practice with “Attachment Disorders.”

  2. Holding therapies tend to direct the intervention to the child him or herself. In contrast, all attachment research-based interventions with which we are familiar, including the Circle of Security™, are designed to impact the child’s attachment pattern indirectly by directly focusing on caregiver patterns of behavior and thinking. This practice follows directly from Ainsworth’s focus on caregiver sensitivity to the child’s cues as perhaps the major variable in predicting security of attachment.

  3. Holding therapies tend to view the behavior- and emotion-regulation problems of children with attachment difficulties as unacceptable behaviors, and often make inferences about negative intent on the part of the child. Most holding therapies attempt to eliminate or extinguish these intentions and behaviors through consistent, strong, and often negative, consequences that are based either on aversive behaviors toward the child, or on temporary separation, or interruption of the interaction, between the child and caregiver. In contrast, interventions based on attachment theory are likely to view the behavior- and emotion-regulation problems associated with attachment difficulties as patterns of thinking and behavior that are both an understandable adaptation to the child’s unique developmental and relationship history, and are reflections of the child’s inability, at the moment, adequately to self-regulate his or her affect and behavior. Even if the child is acting in an aggressive, controlling manner, attachment-based interventions will, in most but not all situations, view the child as anxious, vulnerable, “in over his head,” out of control, and needing the parent’s empathy, soothing, and management.
