Poor Individual Risk Classification From Adverse Childhood Experiences Screening.

Area of Science:

• Public Health
• Psychology
• Epidemiology

Background:

• Adverse childhood experiences (ACEs) are linked to increased physical and mental health risks.
• Routine clinical screening for ACEs is proposed, but individual-level accuracy is debated.
• Previous research highlights the population-level association between ACEs and health outcomes.

Purpose of the Study:

• To evaluate the accuracy of the ACE score in discriminating between adults with and without health issues.
• To assess the clinical utility of a high-risk ACE exposure definition (≥4 vs. 0-3 ACEs).
• To determine the predictive values and likelihood ratios for health risk classification based on ACEs.

Main Methods:

• Utilized data from the 1995-1997 ACE Study.
• Calculated area under the curve (AUC) for continuous ACE scores.
• Evaluated binary ACE classification (≥4 vs. 0-3) using sensitivity, specificity, PPV, NPV, and LRs.

Main Results:

• Discrimination for continuous ACE scores ranged from very poor to fair (AUC=0.50-0.76).
• Binary classification showed high specificity and negative predictive values.
• Sensitivity and positive predictive values were low; likelihood ratios indicated minimal-to-moderate risk increases.

Conclusions:

• ACE screening based on current scores may not accurately identify individuals at high health risk.
• This inaccuracy could lead to inappropriate resource allocation (unnecessary interventions or missed support).
• Further research is needed to refine risk identification strategies beyond simple ACE scoring.
