The language of suicidology has been confusing for the past half-century, thereby inhibiting effective study of the problem of suicide. This dissertation’s survey research compared two nomenclatures: the Columbia Classification Algorithm of Suicide Assessment (C-CASA; Posner, Oquendo, Gould, Stanley, & Davies, 2007) and the Silverman nomenclature (Silverman, Berman, Sanddal, O’Carroll, & Joiner, 2007a and 2007b). Hypothetical vignettes were constructed to represent the different terms and definitions of each of the two nomenclatures; ten vignettes were randomly selected to be presented to participants. The 131 participants were mental health clinicians who were currently seeing clients for at least five hours per week. The hypotheses were that the C-CASA would exhibit better reliability and significantly better perceived clinical utility than the Silverman nomenclature. Perceived clinical utility was measured by a new 13-item questionnaire constructed for the purposes of this study. An exploratory factor analysis indicated that the perceived clinical utility questionnaire had a stable one-factor structure and an alpha of 0.95. The data supported both hypotheses. C-CASA’s reliability, as measured by kappa statistics, was 0.59, while the Silverman nomenclature’s was 0.45; this was more than a 0.1 difference in C-CASA’s favor. On the 7-point Likert-type scale of the perceived clinical utility questionnaire, the Silverman nomenclature received positive scores that were a bit above neutral (4.62), while the C-CASA received scores almost a point higher (5.43), which were almost halfway between “neutral” (4) and “strongly agree” (7). These differences were statistically significant and represented a large effect size (Cohen’s d was 0.83). These differences suggested that the C-CASA was preferable to the Silverman nomenclature, both in terms of reliability and perceived clinical utility. If replicated by other researchers, this result would mean that the C-CASA showed more promise than the Silverman nomenclature for constructing a common language for suicide-related thoughts and behaviors among practicing clinicians. 2013-05-10 English text University of Akron / OhioLINK http://rave.ohiolink.edu/etdc/view?acc_num=akron1365533457 http://rave.ohiolink.edu/etdc/view?acc_num=akron1365533457 unrestricted This thesis or dissertation is protected by copyright: all rights reserved.
