Brief Psychological Approaches

Structured models of time-limited psychological practice documented within the IISTP Registry.

What Defines an Approach?

An approach represents a structured theoretical model designed to guide psychological work within a defined framework. IISTP documents recognized brief models currently included in the Registry.

Time-Limited Structure

The model operates within a clearly defined short-term framework, with identifiable duration parameters and focused therapeutic direction.

Theoretical Coherence

The approach is grounded in a consistent conceptual framework that defines its view of human functioning and change.

Defined Intervention Methodology

The model presents specific, describable intervention processes rather than general therapeutic orientation.

Structured Session Logic

Sessions follow a recognizable structure, including focus, progression and defined therapeutic objectives.
