Neglect and adolescent internalizing mental health: Testing competing longitudinal hypotheses

Area of Science:

• Child Psychology
• Developmental Psychology
• Public Health

Background:

• Child neglect is understudied relative to other maltreatment forms.
• Previous research indicates neglect negatively affects adolescent mental health.
• The specific timing (critical period vs. cumulative effects) of neglect's impact remains unclear.

Purpose of the Study:

• To compare critical period and cumulative effects hypotheses of neglect.
• To examine the impact of failure to provide (FTP) and lack of supervision (LOS) on adolescent depression and internalizing symptoms.
• To utilize a novel approach within the LONGSCAN consortium data.

Main Methods:

• Prospective, multi-site study (LONGSCAN consortium) of children aged 2-16.
• Analysis comparing critical period (childhood vs. adolescence) and cumulative neglect exposure models.
• Assessment of neglect's effects on adolescent depression and internalizing symptoms, controlling for other maltreatment.

Main Results:

• Adolescent neglect (ages 12-16) best predicted depression from failure to provide (FTP) and both depression and internalizing symptoms from lack of supervision (LOS).
• Cumulative neglect exposure best explained FTP neglect's impact on internalizing symptoms.
• Findings remained significant after controlling for other forms of maltreatment.

Conclusions:

• Neglect during adolescence has a pronounced impact on mental health outcomes.
• Both critical period (adolescence) and cumulative exposure models are relevant, depending on the type of neglect and outcome.
• Child welfare systems must prioritize interventions for neglect extending into adolescence.
