The Boulder Conference, held in 1949, marked a significant turning point in the field of clinical psychology. During this conference, a group of influential psychologists came together to define a new approach to the practice of clinical psychology. This approach, known as the Boulder Model, emphasized the importance of both science and practice in the field.

The Science-Practice Gap

Before the Boulder Conference, there was a noticeable gap between scientific research and clinical practice in psychology. Many psychologists focused solely on conducting research and did not consider the practical applications of their findings. On the other hand, some clinicians relied heavily on their intuition and personal experiences without considering scientific evidence.

The participants at the Boulder Conference recognized this gap and aimed to bridge it by integrating science into clinical practice. They believed that clinical psychology should be based on empirical evidence and scientific principles.

The Founding Principles

One of the key outcomes of the Boulder Conference was the establishment of four founding principles that would shape the future of clinical psychology:

The Impact

The Boulder Model had a profound impact on the field of clinical psychology. It paved the way for the integration of science and practice, ensuring that psychological interventions were evidence-based and effective. The model also led to the development of rigorous training programs that produce competent and well-rounded clinicians.

Furthermore, the Boulder Model helped establish clinical psychology as a distinct profession with its own unique identity. Today, clinical psychologists are recognized as experts in applying scientific principles to understand and treat mental health issues.


The Boulder Conference marked a significant milestone in the field of clinical psychology. The approach that emerged from this conference, known as the Boulder Model, emphasized the integration of science and practice in clinical psychology.

By bridging the gap between research and practice, this model has shaped the field and ensured that psychological interventions are evidence-based and effective.
