⚙ AI-generated deep summary by claude@2026-07, 2026-07-16 · read from full text ⓘ

The paper’s supplemental materials relate to an article that used an expanded Theory of Planned Behavior framework to explain women’s intentions to disclose menstrual discomfort, assessing how endometriosis knowledge and menstrual stigma relate to intentions. At a high level, the supplement includes model assessment documentation, multigroup analysis materials, a self-test component, and subsample analyses, aimed at evaluating how the proposed model fits and whether relationships differ across groups. A key caveat reflected in the supplement’s framing is that the authors present materials as submitted, with APA noting assumptions about errors/omissions and making no warranties, alongside presentation of analyses without guaranteeing completeness. Relevance to endometriosis: endometriosis knowledge is a core predictor in the theory-expansion used to model disclosure intentions for menstrual discomfort, though the paper’s main focus is menstrual-discomfort communication intention rather than directly studying endometriosis biology.
