No previous studies have explored the factor structure of the Columbia-Suicide Severity Rating Scale (C-SSRS), comparing the results across different age groups. The researcher hypothesized that the factor structure for children and adolescents would be different from that of adults on the C-SSRS. Using SPSS, version 23, the researcher employed principal axis factoring and direct oblimin rotations methods on a secondary dataset of 227 electronic medical records of individuals (M = 26.93, SD = 13.13) residing in a metro area of Georgia. The researcher then compared the factor loadings of Preadolescents, age 10 to 15 (n = 52), Adolescents, age 16 to 24 (n = 66), and Adults, age 25 and older (n = 109). One of the subscales was eliminated from the study, the Lethality subscale, due to missing data. The Behavior subscale, was not included in group comparisons due to less than acceptable internal consistency and Kaiser-Meyer-Olkin (KMO) values for factor analysis (Kaiser & Rice, 1974), thus limiting the findings. The comparisons by age group using partial group information from the Intensity subscale also excluded the adolescent group from the comparison due to the less than acceptable KMO value. Findings from the Suicidal Ideation scale indicated that two factors (lifetime, and past 1 month) captured the constructs for the preadolescent group more than it did for the adolescents and adults, with the widest margin being between the preadolescents and the adult group. Recommendations are made for further research regarding whether modification of the Lethality subscale may be warranted, and for the suitability of the Suicidal Ideation scale in assessing for suicidality in preadolescents and adults. Findings on the latter scale appeared to support the hypothesis; however, the limitations need to be taken into consideration regarding these findings.
