The tool (additional file 1) includes twelve questions (15 items) that reflect each of the key TPB constructs: generalized intention (items 1 to 3); attitude (items 4a to 4d); subjective norm (items 5 to 8); and, perceived behavioural control (items 9 to 12).
Specific subscales assessing following syndromes were selected: major depressive syndrome (9 items), generalized anxiety syndrome (7 items), somatoform syndrome (13 items) and panic syndrome (11 items).

We used the Japanese version of the 7-item generalized anxiety disorder scale (GAD-7) to assess generalized anxiety disorder.
These two subscales include 16 items (7 items on social anxiety and 9 items on generalized anxiety) and it takes approximately 5 minutes to complete the questionnaire.
We recall that the triple in Definition 2.1 is called an ordinary boundary triple (generalized boundary triple) if item (ii) is replaced by the condition ({{mathrm{ran}}}(Gamma )=mathcal {H}^2) (({{mathrm{ran}}}(Gamma _0)=mathcal {H}), respectively).
Typically, NAEP uses the three-parameter logistic (3PL) model for dichotomously scored items and the generalized partial credit model for polytomously scored items.
In Study 1, a pool of 77 items reflecting generalized pliance was designed.
Many validated outcomes measures for cervical spondylotic myelopathy already exist, ranging from the disease-specific Nurick grading scale to the generalized Short Form 36-item (SF-36) questionnaire.
