APEX© – An Effective Model for Treating Non-Suicidal Self-Injury

November 19, 2021

Drawing on evidence-based principles Diane Clare created the Alternatives to Self-Harm approach and designed the APEX© model that underpins this way of working with people who engage in non-suicidal self-injury. In this webinar she will outline the components of the APEX© model and how you might use them in practice. She compares the APEX model with treatment as usual and considers the core differences between APEX and DBT (Dialectical Behavior Therapy). The importance of Attitude in how we explore the purpose of self-harming is described. You will develop an understanding of why the Purpose(s) of the harming is important for achieving change. Diane will describe ways this model helps people match these purposes with strategies that meet their needs in less harmful ways. This is illustrated in the form of matched Emotional First Aid Kit ideas. The X factor of the model is a self-contract, which will be described, with examples. You will be invited to consider ways in which this model could enhance and support other approaches and therapies.
