Determination of the optimal cutoff point for the suboptimal health status questionnaire: a latent profile analysis.

ABSTRACT:

Background

The Suboptimal Health Status Questionnaire (SHSQ-25) is a widely used tool for assessing suboptimal health, however, the determination of an optimal cutoff point remains unclear. This study aimed to determine the optimal cutoff point for the SHSQ-25 using latent profile analysis (LPA) and receiver operating characteristic curve (ROC) analyses.

Methods

A cross-sectional online survey was conducted among adults aged 18 years and above in five regions in China. Participants completed questionnaires assessing demographic characteristics and suboptimal health status using the SHSQ-25. LPA was applied to identify distinct subgroups based on participants' responses to the SHSQ-25 items. ROC analysis was performed to establish the optimal cutoff point for the SHSQ-25. The
