Boundaries Test (DSI-R)

The Differentiation of Self Inventory (DSI-R) was developed by psychologists Elizabeth A. Skowron and Thomas A. Schmitt in 2003 to measure a person's capacity to balance two of the most fundamental human needs: the drive for connection and the drive for individuality. Rooted in family systems theory, the concept of self-differentiation describes how well you can maintain your own thoughts, feelings, and sense of identity while staying deeply connected to the people you care about. When boundaries are healthy, you can navigate close relationships without losing yourself in them or, conversely, shutting others out to protect your independence.

This test profiles your boundary strength across four distinct dimensions. The first, Emotional Composure, reflects your ability to remain calm and level-headed during stressful situations or interpersonal conflicts, rather than becoming overwhelmed by immediate emotional reactions. The second dimension, I Position, measures your capacity to stand by your personal convictions and maintain a clear sense of who you are, even when others pressure you to conform or change your behavior to please them. Together, these two facets capture the internal side of boundary strength, showing how you manage your thoughts and feelings under pressure.

The remaining two dimensions focus on how you navigate your connections with others. Comfort with Closeness measures your willingness to share your true self and express vulnerability without fearing that intimacy will swallow your identity or lead to painful rejection. Independence, the final facet, assesses your ability to maintain healthy boundaries without becoming overly fused with others or taking on their problems as your own. By scoring the positive poles of these traits, the test ensures that higher scores consistently reflect stronger, healthier boundaries that support both intimacy and self-reliance.

Decades of research using the DSI-R have shown that higher levels of self-differentiation and boundary strength are strongly linked to psychological well-being and relationship satisfaction. Individuals with well-developed boundaries tend to experience lower levels of chronic anxiety, fewer physical symptoms of stress, and greater emotional stability. In relationships, they are better equipped to handle conflicts constructively, as they can separate their thoughts about an issue from their feelings about the person. They are also less likely to fall into patterns of emotional codependency or defensive withdrawal, leading to more secure and fulfilling partnerships.

Alongside your results, the chart displays estimated population comparison markers to help you put your scores into context. These markers are approximations rescaled from published research samples using the original DSI-R, where a typical adult's total score lands near 3.7 on a 1-to-6 scale, or roughly 54%. Because these markers are estimates derived from academic studies rather than validated percentile norms for this specific online test, they should be treated as a general point of reference rather than a precise or absolute ranking of your personal boundary strength.

This test is provided for educational and entertainment purposes only. It is not a diagnostic instrument and cannot provide a clinical assessment of your mental health or relationship functioning. The test is based on the Differentiation of Self Inventory (DSI-R) but uses its own items and is not affiliated with Skowron, Schmitt, or their respective institutions. If you are experiencing significant distress in your relationships or personal life, please consider reaching out to a qualified mental health professional for personalized guidance and support.
