Preview dimensions and interpretation

These tendency scores are calculated from this survey’s responses. Each independent 0–100 index is not a disease probability, medical risk level or population ranking.

Every item contributes an equal weight of 1 to its assigned dimension. Sum valid 1–5 answers minus 1, divide by (valid item count × 4), then multiply by 100. Not applicable, declined answers and the experience gate are excluded from numerator and denominator. Each dimension requires at least two valid answers and at least half its items. Any withheld dimension suspends overall comparison; prominent items are shown only when all dimensions can be calculated and the maximum is at least 25. This display rule is editorial, not a clinical threshold.

  • Urges and craving: Answers about thinking of nonmedical use or strong urges stood out relatively. A professional can help discuss the context of these urges.
  • Control over nonmedical use: Answers about difficulty following plans to reduce or stop nonmedical use stood out relatively. Consider a professional assessment rather than judging this alone.
  • Substance-related life effects: Answers about health, responsibilities, relationships or continuing after problems stood out relatively. Persistent effects warrant a conversation with a health professional regardless of score.

Before you start

This original self-check draws on research concepts; it is not a standardized test or diagnostic tool. Its questions, weights and minimum-answer rules are editorial choices without clinical validation. You may decline or choose not applicable, and interpretation depends on your circumstances and responses. Use experience alone does not establish dependence or addiction. We do not ask for substances, sources or use methods; do not stop or change prescribed treatment based only on this result.
