Schizophrenia has positive and negative symptoms that are both analysed using a traditional cognitive model. The model exists of the cognitive triad: schemas about self, world and the future. When interventions are made, they should target the meaning behind both positive and negative symptoms. However, in the current system, the content for both symptoms is similar. The view of the self is weak, vulnerable, ineffective and worthless. The view of others as controlling, dangerous and rejecting.
Cognitive schemas are responsible for cognitive organization. The content originates from the cognitive triad. If schemas interfere with accommodation in life situations, they are called dysfunctional. If schemas are extreme of fantastic, they are called delusional.
Schizophrenia can develop due to a genetic predisposition in combination with the development of negative thoughts and stressful life-events. These negative thoughts become embedded into cognitive schemas and a person can develop negative symptoms, such as withdrawal, violence and isolation. On the other hand, positive symptoms can come from dysfunctional symptoms and get transformed into delusions. These symptoms start with an overstimulation of the HPA axis which leads to an excessive output of cortisol. That leads to an overflow of dopamine and the development of hallucinations.
Motivation is one of the main factors in developing negative symptoms. There are two ways that motivation affects the symptoms, in belief and expression.
Evaluation of the self has an influence on negative symptoms. Positive evaluations lead to less negative symptoms. On the other hand, dysfunctional beliefs correlate to the severity of negative symptoms. It was found that a lower self-efficacy leads to more severe negative symptoms. The three components of the cognitive triad (self, others and future) express themselves in specific situations in the context of task orientation, pleasure, interpersonal relations and energy.
Negative symptoms are related to beliefs about the future, negative thoughts about task performance or future success corelate with severe negative symptoms. Individuals that have the deficit syndrome (more severe negative symptoms) have more defeatist beliefs then those that do not experience severe negative symptoms. Furthermore, a decrease in the expectation of pleasure can contribute to more negative symptoms. Asocial beliefs also play a role and correlate with asociality in schizophrenia.
Development of positive systems is labelled the transformational or imaginal system. It is isolated from other cognitive functions. The connection with the cognitive triad is the same. It is based on an exaggeration of fears or fantasy. However, negative symptoms represent expectancy of failure whereas positive symptoms embody the basic universal needs such as acceptance. Symptoms can become less prevalent after a series of positive experiences or by becoming part of an active social network. By helping other people both negative and positive symptoms can be reduced. Automatic thoughts can be positive, critical or about other people and events. These command hallucinations are often ascribed to a powerful individual such as god. They also reflect an exaggerated fear.
Research has shown that negative cognitive schemas about the self, predict positive symptoms. It is suggested that negative symptoms occur before positive symptoms. A lower self-esteem and more negative evaluations result in delusions and greater suicidal ideation. Beliefs about the self being powerful lead to decreased distress. Beliefs about other correspond to more severe hallucinations. People with schizophrenia tend to believe they are inferior to others. Consequently, negative beliefs about the future result in the expectation of criticism and rejection. Negative self-esteem and expectations showed a high correlation with paranoid delusions.
