might be a contraindication for group‐ST for BPD. Similarly, specific narcissistic traits, manifested as poorly controlled denigrating others, are a risk for group‐ST.

Rationale of Treatment/Theories Supporting Treatment

      ST as described by Young states that everyone develops schemas during childhood. A schema is an organized knowledge structure, which develops during childhood and manifests in certain behaviors, feelings, and thoughts (Arntz, 2018; Arntz & Lobbestael, 2018). While a schema is not directly measurable, it can be gauged by analyzing the patient's life history and observing the manner in which she deals with her temperament and talents. This becomes more evident and observable as the patient shares more details about her behavior in various social situations and the life rules and strategies to which she adheres.

      Healthy schemas develop when the basic needs of a child are met. This enables children to develop positive images about other individuals, themselves, and the world as a whole.

      The basic needs of children include:

       Safety – Children must be able to depend on a reliable adult for care and a safe place to live, develop, and grow.

       Connection to others – Children must feel that they are connected to others and are able to share their experiences, thoughts, and feelings with others.

       Autonomy – Children must have a safe and secure environment from where they can explore and learn about the world. The ultimate goal of maturing to adulthood is for them to eventually stand on their own two feet. Caregivers must slowly but surely allow children to separate from them in order to grow into autonomous adults.

       Self‐appreciation – Children must have an adequate sense of appreciation. In order to develop a strong sense of self‐esteem, they must be appreciated for who they are as people and what they are capable of doing.

       Self‐expression – The expression of one's opinions and feelings must be learned and stimulated without being held back by strict or oppressive rules.

       Realistic limits – In order to live in a society with others, it is necessary for children to learn certain rules. They must understand when to subdue their autonomy or self‐expression when dealing with others and be capable of doing so. Children also have to learn to tolerate and adequately deal with frustrations (Young & Klosko, 1994; Young et al., 2003).

When these needs are not met, whether solely due to shortcomings in the child's environment, or in combination with traumatic events (such as emotional, physical, or sexual abuse, or being bullied), this can form—in interaction with the temperament of the child—dysfunctional schemas and coping strategies (see Figure 2.1). The dysfunctional schemas that are formed during childhood development are called “early maladaptive schemas.” Given the circumstances in which the child grew up, they are usually understandable (e.g., a child growing up in an environment where there is a lot of threat of abandonment has an increased risk to develop an abandonment schema). Young describes 18 different early maladaptive schemas (see Appendix I) and three groups of coping strategies (see Appendix J) (Young et al., 2003).

      The schemas and coping styles form a sort of alternative for the personality disorder diagnostic system in the DSM‐5 (American Psychiatric Association [APA], 2013). For BPD, so many schemas have been found that a treatment based solely on a schema conceptualization would be very complex. Moreover, the 18 schemas and three coping styles lead to 54 possible combinations, further complicating the task to understand the patient's problems with this model.

Schema Modes

      Patients with BPD often have so many different schemas present at the same time that both patient and therapist cannot see the wood for the trees. Because shifts in behavior and feelings take place so quickly, it is difficult for the patient herself, let alone for those around her, to understand what is taking place. This further exacerbates an already complex problem. These sudden shifts in patterns of feeling, thinking and behavior, which are so common in BPD, have inspired the development of the concept of a “schema mode” (also called “mode” or “schema state”) (McGinn & Young, 1996). A schema mode is a set of schemas and processes, which, in certain situations, determine the thoughts, feelings, and actions of the patient at the cost of other schemas. In other words, when the BPD patient is relatively relaxed and comfortable, one sees a totally different side of her personality as opposed to when she feels threatened. Under normal circumstances, one sees a relatively quiet patient who appears to have few emotions. However, when, for example, the threat of abandonment by an important figure is posed, one sees a “young child” being very upset and completely inconsolable. A patient with BPD can switch from one strong mood or emotion to another in a very short period of time. According to the schema mode model, this is due to the patient's continual and uncontrolled shifts from one mode to the other.

      It is important to understand that schema modes are related to schema's, and that there is no fundamental difference between schema theory and schema mode theory. The schema model as formulated by Young et al. (2003) states that when an early maladaptive schema is triggered, or is threatened to be triggered, people use specific ways of coping to deal with this activation, as the activation is usually experienced as highly unpleasant and signaling threat. The ways of coping are grouped in three coping styles: overcompensation, avoidance, and surrender—analogous to the primitive coping under high stress common to mammals (fight, flight, freeze). The combination of a schema that is (threatened to be) triggered and a coping response is a schema mode. In other words:

Two studies have actually supported this model, in that they demonstrated that coping indeed determines how modes are related to schemas (in statistical terms: the coping style mediates the relationship between schemas and modes) (Rijkeboer & Lobbestael, 2012; van Wijk‐Herbrink et al., 2018). The last study even went one step further, demonstrating that the very same early maladaptive schemas can underlie internalizing as well as externalizing psychopathology, and that it depends on the type of coping, hence the schema modes, whether a (threatened) schema activation results in internalizing or externalizing psychopathology:

      Thus, in the phase of case conceptualization (see Chapter 3) it is meaningful to combine the mode model as described below with the specific schemas that give “color” to the mode of your individual patient. When patient A is in the abandoned/abused child mode she might feel stupid (schema defectiveness/shame) and distrustful (schema mistrust/abuse) while patient B might feel abandoned (schema abandonment/instability) and dependent (schema dependence/incompetence).

Young suggested that the following five modes are characteristic of BPD: the detached protector, the abandoned/abused child, the angry/impulsive child, the punitive parent, and the healthy adult (actually, a weak healthy adult mode). Recently an extra important mode has been added to the model: the happy child mode, which is also weak in BPD. In some cases, we also see an undisciplined or impulsive child, which we will describe in combination with the angry child. These modes can be renamed to make them more
