Abstract: The psychotherapy literature emphasizes the importance of the differentiation process for healthy individual development. One of the key characteristics of Positive Psychotherapy is its grounding in differentiation. The purpose of this study is to develop a model that will help clients achieve intrapersonal differentiation across five stages, using five capabilities grounded in Positive Psychotherapy. The developed model is referred to as the Positive Intrapersonal Differentiation Model (PID Model). According to the model, honesty is used in the observation stage; patience in the inventory stage; hope in the situational encouragement stage; achievement in the verbalization stage; and time capability in the broadening of goals stage. The study also provides an example of a psychotherapy session based on the PID Model. The developed model can be used in the process of intrapersonal differentiation.
