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 ] 186 phenomena captured by the C–SSRS was two points lower than the highest score of the passive suicidal ideation phenomena captured by the S-STS. On two of these six dates (Day 6 and Day 73), the C–SSRS passive suicidal ideation score was 0. This is due to the thought, "I need to be dead," which is not on the C–SSRS, but is on the S-STS, being rated as extreme on the days of the impulsive suicidality under study. Discussion. More often than not, the C–SSRS underestimated the passive suicidal ideation phenomena that occurred on the days of impulsive suicidality in this case study. Result 8. Table 1 is the correlation matrix of the five passive suicidal ideation questions and impulsive suicidality. The S-STS has the first three of these questions while the C–SSRS has the last three of the five passive suicidal ideations. The S-STS and the C–SSRS both captured the thought, "I wish I were dead" (question 3). The three S-STS questions were only weakly and sometimes negatively correlated with each other. Consistent with and for the same reasons cited in Results 7 above, there was a high correlation between the "need to be dead" and impulsive suicidality (0.79). Discussion. In order to capture the broadest range of passive suicidal ideation experiences using the fewest number of questions from the five available, the best strategy was to select those that were not correlated well with each other and to include even those negatively correlated with each other, if available. Based on the above "choice strategy," the three questions in the S-STS had broad diversity, while the three C–SSRS questions had less diversity. Result 9. Table 2 investigates the relationship between a positive response to the passive suicidal ideation question, "Do you think you would be better off dead?" and work/ school impairment, social/leisure impairment, family life/home responsibility impairment, total functional impairment, and quality of life scores. These results reflect the impairment scores captured weekly and the sum of the daily scores for the same week for all five passive ideations. It also investigates the relationship between the S-STS passive ideation score, the C–SSRS passive ideation question, and the same measures of impairment and quality of life. The above results are very similar to those found in studying the relationship between the daily impairment and quality of life scores and the daily passive ideation scores. Discussion. "Better off dead" and functional impairment. The results show a good correlation between thoughts of being better off dead and social life/leisure activities impairment (0.57) and total functional impairment scores (0.54). The relationship between thoughts of being better off dead and family life/home responsibilities score were modest (0.38). There was a weak positive relationship between FIGURE 3.
