Differentiation of Self Test
Differentiation of self — a core idea of Bowen family systems theory — is the ability to stay yourself while staying connected: to feel your feelings without being swept away, and to hold your position without cutting people off. This free 24-question reflection maps four dimensions: emotional reactivity, I-position, emotional cutoff, and fusion with others.
What it measures
Emotional reactivity (how strongly others ignite you), I-position (holding your own stance under pressure), emotional cutoff (managing closeness through distance), and fusion with others (where your feelings blur into other people's).
Emotional reactivity
How quickly and strongly other people's words and moods ignite your own.
I-position
Your ability to hold your own position under pressure — shown as a strength score.
Emotional cutoff
Using distance and silence — rather than engagement — to manage closeness.
Fusion with others
How much your feelings, plans, and worth blur together with the people around you.
About this test
This is an original, education-oriented reflection. Its four dimensions follow the constructs of Bowen family systems theory as measured by the Differentiation of Self Inventory (DSI-R; Skowron & Schmitt, 2003): emotional reactivity, I-position, emotional cutoff, and fusion with others. All items were written for this test.
It is for self-reflection and education only: it is not a diagnostic tool, and differentiation is a capacity that develops across a lifetime — a lower score is a starting point, not a label. If family situations currently feel unsafe, please prioritise your safety and consider professional support.
Note on cutoff: keeping distance from family can be a healthy choice. This test describes your default tools, not whether you are allowed to use them.
How to read your result
You'll see an overall differentiation level, a four-bar profile, and — when one dimension stands out — a pattern card with a core belief, a strategy, and small steps.
Differentiation is a skill, not a personality type. Scores describe your current defaults under pressure; they are meant to be moved, not defended.

A closer look
Why 'staying yourself while staying connected' is the skill this test measures.
Interpretation approach
Each dimension is shown as a percentage; I-position is displayed as a strength. The overall level uses four plain-language bands. No dimension is framed as shameful — cutoff in particular gets an honest note, because distance is sometimes the wisest tool available.

Frequently Asked Questions
Have another question? Let us know.
What is differentiation of self?
A concept from Bowen family systems theory: the ability to hold on to yourself while staying emotionally connected to others — feeling your feelings without being flooded by them, and keeping your own position without needing distance or victory.
What are the four dimensions?
Emotional reactivity (how strongly others' words and moods ignite you), I-position (holding your own stance under pressure), emotional cutoff (using distance and silence to manage closeness), and fusion with others (your feelings and worth blurring into other people's).
Is a lower differentiation score bad?
No. Differentiation is a capacity that grows across a lifetime, and almost everyone is less differentiated under some kinds of pressure than others. A lower score marks where the skill has room to grow — it is a starting point, not a label.
Does a high cutoff score mean I'm cut off from family in the wrong way?
Not automatically. Distance can be healthy self-protection, especially where contact itself is harmful. The cutoff dimension only describes how much distance is your default tool — the results page adds this note too.
How is this related to the family-of-origin test?
They are complementary. The family-of-origin test looks at the system you grew up in and how it still shows up; this test looks at one specific capacity — staying yourself while staying connected — that Bowen theory sees as forming in that system.
How is the score calculated?
Each dimension is shown as a percentage with a plain-language band; I-position items are flipped so that they display as a strength. The overall differentiation level is the inverse of the average pressure across the four dimensions. Nothing is pass/fail.
