Researchers tested whether the World Health Organization’s Adverse Childhood Experiences–International Questionnaire (ACE‑IQ) works well for adolescents in a low‑income setting. It does—and it helps flag mental‑health risk.
What’s new
- In a study of 410 adolescents aged 10–16 in Malawi, the ACE‑IQ showed a clear three‑part structure capturing household disruption, abuse, and neglect.
- The questionnaire demonstrated predictive validity: higher ACE‑IQ scores were linked with more depressive symptoms on the Beck Depression Inventory (r = 0.35).
- Asking about when harms occurred mattered. Adding “in the last year” (alongside “ever”) modestly improvedhow well ACE‑IQ scores predicted depression (model R² rose from .12 to .15).
- Reports from youth sharing the same caregiver showed moderate similarity (ICC = 0.43), supporting reliability.
Why it matters
Most evidence behind ACE screening comes from wealthier countries. Showing that the WHO’s ACE‑IQ is appropriate for Malawian adolescents supports its use in resource‑limited settings, helping schools, clinics, and community programs identify youth who may benefit from early mental‑health and social support.
Details & caveats
- The team found that adding a few HIV‑related adversity items provided little extra predictive value in this sample (low endorsement and only modest correlation with depression).
- As with most survey research, findings rely on self‑report, and the study assessed prediction of depressive symptoms, not clinical diagnoses.
The bottom line
This peer‑reviewed study, published in Child Abuse & Neglect, indicates the ACE‑IQ is a useful, valid tool for gauging childhood adversity among Malawian adolescents, with practical tweaks (like asking about recent experiences) that can sharpen risk detection for depression.
