Integrative Focus: Systematic + Eclectic Variable Individual

Core Mechanism

Systematic assessment across all seven modalities of human functioning (BASIC I.D.) identifies the specific constellation of problems and firing order, enabling targeted interventions drawn eclectically from any effective tradition

Ontology

Human problems are multimodal — they involve behavior, affect, sensation, imagery, cognition, interpersonal patterns, and biology in varying combinations; single-modality treatments miss the full picture

Therapeutic Voice

"Let's map the full picture — what's happening in your behavior, feelings, body, images, thoughts, relationships, and health?"

View of the Person

A multimodal being functioning across seven interconnected domains — effective treatment must assess and address the specific modality profile rather than imposing a single theoretical lens


Evidence

Not in major guidelines

Limited RCTs; more case study and process research

None as standalone

Historically important as the most systematic integrative/eclectic framework. Lazarus coined technical eclecticism — use techniques from any tradition based on evidence, without adopting the theory. BASIC I.D. assessment is still taught. Influenced the movement toward evidence-based integration.


Conditions

Epistemology

PragmatistEmpiricist

Blind Spots

Technical eclecticism risks superficiality — borrowing techniques without understanding their theoretical context; framework is descriptive rather than explanatory; limited controlled research

Contraindications

Active psychosis, severe cognitive impairment, situations where the breadth of the BASIC I.D. assessment delays urgent clinical priorities, clients who need depth in one modality rather than breadth across multiple


Training

Graduate integrative coursework + BASIC I.D. framework. Self-study sufficient

No active certification

Self-study; graduate coursework

Minimal


Philosophical Roots

Pragmatism (what works regardless of theory); Lazarus explicitly rejected theoretical integration in favor of technical eclecticism; behaviorism (Lazarus trained with Wolpe); empiricism; Korzybski (general semantics — the map is not the territory)

Test Yourself

What is the BASIC I.D.?

Show answer

An assessment framework covering seven modalities: Behavior, Affect, Sensation, Imagery, Cognition, Interpersonal relationships, and Drugs/biology. Comprehensive treatment addresses whichever modalities are most relevant for the individual.
