Table 8 Presentation of examples of further modified severity assessment on Criterion A

From: Symmetrical treatment of “Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition”, for major depressive disorders

  1. The indication for item selection as being effective; Ar = [11|02|13|04|15|16|17|08|19||0 10 |0 11 |0 12 |…] (mod 2) over Table 3
  2. A further modified (sub)scale based on Criterion A is presented. Here, the first, third, sixth, seventh and ninth items are effective. The order of effectiveness via selection of items is Ar = [σ123456789||0 10 |0 11 |0 12 |…] (mod 2) = [11|02|13|04|15|16|17|08|19||0 10 |0 11 |0 12 |…] (mod 2). If the j-th row (in this case, j = 1,2,3,…10) in Table 3 is expressed as ‹Aj›, then the modified (sub)scale is provided by the inner product ‹Aj› ∙ Ar, where effective items are denoted by the value 1 and ineffective items by the value 0. The omitted display for the j-th row is given by {‹Aj› ∙ Ar}. If the components with σi = 0 are used at this time; however, these ineffective results of assessments are expected to be stored implicitly and can be pulled out as explicit data when needed in, for example, a future upgrade of criteria of the DSM. The extreme right column indicates the presence/absence of a ‘modified episode’ relating to item selection of Criterion A when the episode needs four of six symptoms for the diagnosis, with at least one of them being symptom (1)
