Innovations in CLINICAL NEUROSCIENCE [ V O L U M E 1 1 , N U M B E R 9 – 1 0 , S E P T E M B E R – O C T O B E R 2 0 1 4 ] 174 positive response to the question "How seriously did you think (even momentarily) about harming or hurting or injuring yourself—with at least some intent or awareness that you might die as a result—or think about suicide (killing yourself)?" 8 (question 3 on the S-STS). In the first timeframe, any positive response to either of these in isolation or in combination was subsumed within the category of suicidal ideation. RESULTS Set 1. Table 2 shows the details of the first set of data collection based upon the combination experienced. F or example, possible combination number 13 (only method and plan) was experienced 15 times on five distinct days and amounted to over 140 minutes during the entire eight months. This combination constituted 0.07 percent of the total number of events and 0.57 percent of the number of minutes spent experiencing suicidality and occurred on 2.05 percent of the days. We are unable to retrieve possible combination numbers 2, 17, and 18, since passive and/or active suicidal ideation were aggregated rather than disaggregated in this earlier dataset. The last two columns to the right in Table 2 identify which combinations would be missed by the FDA-CASA 2012 and C–SSRS suicidal ideation category definitions. (For simplicity, the navigation instructions for the Suicidal Ideation section of the C–SSRS have been ignored here.) As the bottom row of this table indicates, 26 of the 32 possible combinations of suicidal ideation are not recognized by the FDA-CASA 2012 and C–SSRS definitions. Table 3 shows the total number of events, total number of minutes, percentage of events, and percentage of minutes not recognized by the FDA-CASA 2012 and C–SSRS category definitions that were observed during the first eight-month period of observation by the subject of this report. Although only 5.19 percent of the events that occurred would not be recognized, 40.14 percent of the total minutes this subject experienced suicidality in this eight-month period would not be recognized by the FDA-CASA 2012 and the C–SSRS categories. The total amount of time spent in unrecognized events equaled 9,763.4 (9,763) minutes (162 hours, 43 minutes, and 24 seconds) of suicidality over this eight-month period. Set 2 . Data from Set 2 are shown in Table 4. One possible combination TABLE 1.
