Zensitively Neurodivergence Inventory (ZNI): Technical Documentation, Version 1.0

The Zensitively Neurodivergence Inventory (ZNI; German: Zensitively Neurodivergenz-Inventar) is a psychometric self-report instrument with 60 statements answered on a five-point scale. It describes how a person, by their own account, perceives, focuses and reacts, and what this currently costs them in everyday life. It is not intended to detect, monitor or predict disease, or to prepare or support a diagnosis. Seven scales form its measurement core: High Sensitivity, Monotropism, Kinetic-Cognitive Learning Style, Alexithymia, Emotional Overwhelm (associated with rejection sensitive dysphoria, RSD), Camouflaging and Self-Criticism. The figures come from a norm sample of 9,270 German-language first completions between 16 July and 16 September 2026, drawn from a full data set of 155,609 completed administrations. Internal consistencies of the seven scales range from Cronbach's alpha .74 to .91 (McDonald's omega .74 to .91). Stability over two weeks to three months is r = .67 to .79 as observed and .72 to .85 after correction for shared user IDs. Convergent validity: five of the seven scales reach 90 to 95 percent of the correlation that the respective established instrument (HSPS, Monotropism Questionnaire, CAARS, TAS-20, CAT-Q) shows with itself over the same interval; Emotional Overwhelm reaches 83 percent against a clinical screening checklist; Self-Criticism has no validation instrument of its own. Factor structure: a strong general factor with seven specific scales; model fit falls below the strict conventions. Not examined and not claimed: criterion validity against clinical diagnoses, sensitivity, specificity, cut-off scores. This deposit contains the technical documentation (structured after the German TBS-DTK). The 60 items and the scoring rules are proprietary and not included.
