The study measured prior CBD beliefs using three researcher-compiled questions. These ratings described expectations about CBD and should not be presented as diagnoses of anxiety or validated treatment-selection tests.
What participants rated
Before the experimental sessions, participants rated how strongly they believed CBD improved mood, reduced stress and reduced anxiety. Each statement used a ten-point response scale. Separate instruments measured current anxiety, stress and affect during the laboratory procedure.
Those measures served different purposes: a belief about a product is not the same construct as a person’s current symptom intensity.
An association does not supply a clinical cutoff
Participants endorsing stronger prior anxiolytic beliefs reported diminished anxiety in the CBD-expectancy condition in the reported analysis. The experiment did not establish a rating threshold that identifies who should receive CBD or predicts benefit from active medication. Both sessions used CBD-free oil.
Report moderation without inventing a diagnosis
The useful inference is that baseline beliefs can qualify responses to treatment information. It is not that belief ratings diagnosed an anxiety disorder or established a pharmacological responder subgroup. The selected healthy sample, single-item belief measures and overall null stress/anxiety pattern require restraint when transferring the finding to patients or commercial-product claims.
