Identity Style Test (ISI-5)

The Identity Style Inventory (ISI-5) was created by developmental psychologist Michael D. Berzonsky alongside B. Soenens, K. Luyckx, I. Smits, D. R. Papini, and L. Goossens in 2013 to measure how individuals construct and revise their sense of identity. Rather than treating identity merely as a fixed outcome, Berzonsky conceptualized identity formation as a social-cognitive process. People differ in how they process self-relevant information, handle personal decision-making, and navigate fundamental questions about who they are. The ISI-5 identifies the problem-solving strategies, decision-making styles, and cognitive orientations people use when confronting personal choices and defining their goals, values, and commitments in daily life.

The framework examines four primary identity dimensions. The Informational Identity Style describes a proactive, open-minded approach to personal growth; individuals with high informational scores actively seek out relevant information, explore diverse viewpoints, and critically evaluate options before committing to personal decisions. The Normative Identity Style reflects a tendency to adopt and internalize the expectations, standards, and values of family, mentors, or social groups, emphasizing stability, duty, and tradition without prolonged questioning. The Diffuse-Avoidant Identity Style is characterized by procrastination, hesitation, and a tendency to delay or avoid facing major identity choices, letting immediate circumstances or external events dictate life direction. Finally, Identity Commitment captures the strength and clarity of a person's core values, self-definition, and future goals regardless of the processing style used to reach them.

Psychological research shows that these identity styles strongly correlate with various aspects of cognitive processing, decision-making, and emotional well-being. Individuals who rely predominantly on an informational identity style tend to demonstrate high self-reflection, strong problem-solving skills, and adaptive coping mechanisms, though they may experience temporary uncertainty while evaluating options. Those who favor a normative style often enjoy a strong sense of purpose and psychological stability, provided their social environment remains supportive and aligned with their internalized beliefs. Conversely, high scores in the diffuse-avoidant style are frequently linked to emotional distress, lower academic or occupational achievement, and a sense of drift, as essential choices are repeatedly postponed. A strong level of identity commitment across any style generally supports life satisfaction and psychological health.

To provide useful context for your results, the chart displays your profile alongside estimated comparison markers for each identity dimension. These comparison markers are estimates derived from published research samples and statistical summaries, not validated percentiles or standardized norms for this specific web test. They offer a general backdrop to help you interpret your relative strengths across the different processing styles rather than an exact population ranking. Treat these markers as helpful contextual reference points as you review your individual scores across the informational, normative, diffuse-avoidant, and commitment scales.

This test is provided for educational and self-exploration purposes only. It is not a clinical assessment, diagnostic tool, or psychological evaluation, and it does not offer professional mental health advice. Your results reflect your self-reported tendencies at this point in time, not a permanent label or rigid personality classification. This tool is based on the Identity Style Inventory (ISI-5) published in 2013, but it is not affiliated with Michael D. Berzonsky, his co-authors, SUNY Cortland, or any other institution. If you are experiencing distress regarding your life path, values, or mental health, consider consulting a qualified psychological counselor or healthcare professional.
