Despite its central role, susceptibility has remained a qualitative construct without standardized measurement. This study aimed to conceptualize and develop a content-validated instrument to measure susceptibility to different potencies of homeopathic medicines.<\/jats:p>\n An exploratory sequential mixed-methods design (qual \u2192 QUAN) was employed. Conceptual domains were identified through classical literature review and expert free-listing, with item salience estimated using Smith's salience index. Face validity was assessed by four independent raters, followed by Delphi-based content validation with another five-member expert panel using average congruency percentage (ACP), content validity ratio (CVR), content validity index (CVI), including I-CVI (content validity index: item-specific) and S-CVI (content validity index: scale-specific), and kappa statistics. A pilot test by 15 postgraduate trainees (end-users) evaluated clarity and feasibility. An exploratory receiver operating characteristic (ROC) analysis was conducted to preliminarily calibrate score thresholds against expert-rated susceptibility levels (low, medium, high).<\/jats:p>\n From an initial pool of 37 items, 28 were retained after salience analysis and 20 after Delphi validation. Content validity indices met acceptable standards (ACP \u2265 80%; CVR \u2265 0.99; I-CVI Avg. 0.793; S-CVI Avg. 0.786; Fleiss kappa \u22120.037, 95% confidence interval \u22120.120 to 0.045). The final 19-item tool spans intellectual, emotional, pathological, environmental and behavioral domains. ROC analysis demonstrated excellent discriminative performance across all pairwise comparisons (asymptotic p\u2009<\u20090.001), with curves closely approximating the upper-left boundary, indicating high sensitivity and specificity. Optimal cut-off points were identified, enabling empirical classification of susceptibility as low (<60.7), moderate (60.7\u201366.9) or high (>66.9).<\/jats:p>\n This study presents the first standardized, content-validated and pilot-tested instrument to quantify susceptibility in homeopathy. The exploratory ROC findings provide preliminary empirical thresholds for classifying susceptibility levels, supporting more consistent and objective potency selection. Further psychometric testing, including reliability and construct validity, will be reported elsewhere.<\/jats:p>","DOI":"10.1055\/a-2780-4963","type":"journal-article","created":{"date-parts":[[2026,4,30]],"date-time":"2026-04-30T22:38:36Z","timestamp":1777588716000},"source":"Crossref","is-referenced-by-count":0,"title":["Is Susceptibility to Homeopathic Potency a Measurable Construct?
