Introduction:
We performed a taxometric investigation into the underlying structure of suicidal ideation in two diverse samples of nonclinical adult populations.
Methods:
We relied upon one sample of 547 individuals, aged 18-78, who responded to the Beck Scale for Suicide Ideation (BSS), and one sample of 989 participants aged 18-64 who responded to the Suicidal Ideation Attributes Scale (SIDAS). We analyzed the data using different taxometric techniques: MAMBAC, MAXEIG, and L-Mode.
Results:
Our findings suggest ambiguity in the suicidal ideation latent structure (Mean CCFI BSS dataset = 0.46; Mean CCFI SIDAS dataset = 0.45) the results neither indicate any clear tendency toward taxonicity nor toward dimensionality.
Conclusion:
We discuss them based on the possibility that suicidal ideation may represent a complex construct encompassing multiple components.
