Introduction

The Jungian Foundation of the AIIA

At the heart of Jungian psychology lies the tension between the ego and the unconscious. Individuation is the term Jung (1959) used to describe the lifelong process by which the ego becomes increasingly aware of and integrated with archetypal contents, including the Persona, Shadow, Anima/Animus, and the Self. This path requires a symbolic descent into the unconscious, confrontation with repressed aspects of the psyche, and eventual synthesis of opposites into a coherent whole (Neumann, 1954; Jung, 1969).

Jung was adamant that individuation was not about perfection or conformity to any ideal, but about becoming who one truly is—“a process of differentiation, having for its goal the development of the individual personality” (Jung, 1969, p. 173). The path unfolds in symbolic movements, often catalyzed by emotional crises, dreams, projections, synchronicities, and deep self-reflection. In modern terms, these processes can be seen as inner phases that vary in intensity and structure, much like developmental stages.

The AIIA is a modern attempt to operationalize this inner journey without flattening its symbolic richness. While it does not claim clinical diagnostic authority, it offers a reflective mirror for those undergoing psychological transformation—especially those engaged in shadow work, therapy, spiritual growth, or symbolic inquiry.

Overview of the AIIA Individuation Phase Model

The Three Core Indices of Phase Determination

The Archetypal Integration Index

This index reflects the participant’s overall psychological development by summing and normalizing scores across the five archetypal dimensions: Shadow, Anima/Animus, Persona, Inner Sage and Self. It offers a total score (out of 250) which is then converted into a scaled percentage. Higher AII values suggest greater symbolic integration, emotional coherence, and Self-alignment.

Each dimension is scored from 10 to 50 → Maximum total = 250 points
To normalize, sum all five scores and convert to a percentage of 250:

The Growth Activation Index

This index isolates the participant’s score on the Growth Edge dimension—a key indicator of their readiness for psychological transformation. Jung (1969) emphasized that individuation emerges through the tension of the opposites, and the Growth Edge captures that friction.

Conclusion

The Archetypal Integration & Individuation Assessment represents a modern, depth-informed tool for self-inquiry and transformation. By integrating Jungian theory with algorithmic modeling, the AIIA bridges symbolic meaning and psychological measurement. Its nine-phase model and internal indices provide a fluid, reflective map of the individuation journey—honoring the complexity, beauty, and nonlinearity of becoming whole.

In a world that often encourages performance over presence, fragmentation over integration, and distraction over depth, the AIIA offers a much-needed return to inner truth.
