I disagree with Dr. Kuo, who states that the risk set defined in my article was not appropriate. The risk set that I defined as consisting of individuals without depression is appropriate for the article, whose a priori hypothesis concerned the incidence of depressive symptoms, which includes suicidal ideation and anhedonia, among others. The alternative risk set proposed by Dr. Kuo, which consists of individuals without prior suicidal ideation, is appropriate for a study examining the incidence of suicidal ideation in general, such as what he referenced (Kuo et al., 2001). However, it is not appropriate for a study more strictly focusing on suicidal ideation only as a symptom of depression. The post hoc analysis in question was intended to clarify an analysis based on an a priori hypothesis regarding the degree to which individuals without depression symptoms later manifested any depression symptoms that included, but were not limited to, suicidal ideation. The proposed use of a risk set in the post hoc analysis other than that used in the a priori analysis would not clarify the risk of a particular depression symptom among those without depression symptoms at baseline (N=849). The proposed alternative risk set of individuals without suicidal ideation at baseline (N=1,708) would include individuals with other depression symptoms at baseline and would confuse rather than clarify the estimation of the incidence of depression symptoms in total or individually.
