Functional Analysis
A systematic behavioral assessment method identifying antecedents, behaviors and consequences (ABC model) to understand and modify problematic patterns.

Presentation
Functional analysis is a behavioral assessment and conceptualization method that forms the foundation of all cognitive-behavioral interventions. Derived from B.F. Skinner's behaviorism and formalized for clinical practice by several authors (Kanfer, Saslow, Haynes), it aims to understand why a behavior persists by identifying its functional relationships with the environment.
Functional analysis goes beyond describing the problem: it identifies the maintenance mechanisms perpetuating problematic behavior. This functional understanding enables targeted, personalized interventions rather than standardized approaches.
Origins: B.F. Skinner (behavior analysis), Frederick Kanfer and George Saslow (SORKC grid), Jean Cottraux (BASIC IDEA grid in France)
Core Principles
Functional analysis rests on the ABC model (Antecedent — Behavior — Consequence) enriched by several analysis grids:
SORKC grid: Stimulus → Organism (internal variables) → Response → Kontingenz (contingency) → Consequence.
BASIC IDEA grid (Cottraux): Behavior, Affect, Sensation, Imagery, Cognition, Interpersonal, Drugs, Expectation, Attitude.
The central principle is that all behavior persists because it is reinforced — either through positive reinforcement or negative reinforcement (avoidance). Identifying these reinforcements enables effective change strategies.
Main Indications
- All CBT-treated disorders (systematic prerequisite)
- Addictions and compulsive behaviors
- Eating disorders
- Self-harm and risk behaviors
- Pathological anger and aggression
- Procrastination and avoidance
- Behavioral sleep disorders
Session Overview
Functional analysis occurs during initial therapy sessions (1-3 assessment sessions) and continues throughout treatment. The therapist uses structured clinical interviews, patient self-monitoring (recording grids, behavioral diaries) and sometimes direct observation.
For each target behavior, the therapist explores: triggering situations, associated thoughts and emotions, detailed behavior, immediate and long-term consequences, and maintaining reinforcements. The conceptualization is shared with the patient in accessible language, creating shared understanding guiding the treatment plan.
Variations and Sub-techniques
- SORKC grid (Kanfer and Saslow)
- BASIC IDEA grid (Cottraux)
- Chain analysis (DBT)
- Applied functional analysis (ABA — autism)
- Experimental functional assessment
Contraindications
- No specific contraindications as an assessment method
- Requires minimal introspection and communication capacity
- May be difficult during acute crisis (prioritize stabilization)
