Behavioral indicators are often the primary clues to maltreatment in children living with IDD, especially since communication difficulties can prevent the child from making a direct verbal report. Observing sudden or significant changes from a child's typical behavior or developmental baseline is crucial.

Behavioral signs of abuse may be more apparent than physical signs. Common indicators include increased aggression, withdrawal, fear, and changes in eating or sleeping habits. Some children may engage in self-abusive behaviors or have accidental injuries, making it difficult to distinguish between self-harm and abuse.

Emotional and Social Behavioral Changes

Indicators

Signs

Extreme Changes in Demeanor

Shifting from one extreme to another.

Becoming withdrawn, passive, or emotionless (apathy).

Showing excessive aggression, irritability, or disruptive behavior (outbursts, tantrums).

Fear and wariness

Displaying fear or anxiety around a particular caregiver or person, including avoidance or crying when that person approaches.

Being apprehensive when other children cry or act upset, as if expecting something bad to happen.

Showing an unexplained fear of going home or being left alone with a specific individual.

Attachment issues

Exhibiting atypical attachment—either overly compliant and passively accepting all touch or suddenly flinching or recoiling from appropriate physical contact or affection.

Being inappropriately affectionate or friendly with strangers (indiscriminate attachment).

Regression in skills

A sudden and unexplained loss of previously acquired developmental skills (e.g., a toilet-trained child starts bed-wetting, or a child who could feed themselves becomes helpless).

Self-injurious behaviors

An unexplained increase in self-harming behaviors (e.g., head-banging, biting, cutting) that cannot be directly attributed to their disability, as this can be a response to trauma or overwhelming stress.

4.1 Behavioral Indicators of Sexual Abuse

In children with IDD, sexual abuse often manifests as behavioral changes, sometimes appearing as a sudden, intense focus on sexual themes. A child may express inappropriate sexual knowledge or behavior that is beyond their developmental level.

They may engage in sexually suggestive or explicit behaviors with other children, dolls, or themselves, such as masturbation that is sudden or excessive. They may engage in repetitive play or stories that mimic sexual or violent themes.

There may be a sudden and unexplained fear of bathing, toileting, or changing clothes in front of others, complaints of pain or difficulty when walking or sitting, or frequent, unexplained stomachaches or headaches (psychosomatic complaints).

4.2 Behavioral Indicators of Neglect

Indicators of neglect in children with IDD often result from unmet basic needs, such as food, clothing, supervision, and emotional support.

Neglect Indicators

Indicators

Signs

Atypical Eating Behaviors

Hoarding or stealing food, suggesting chronic hunger.

Being constantly fatigued, listless, or falling asleep due to lack of adequate nutrition or rest.

Educational/social withdrawal

Frequent or unexplained absences from school or program settings.

Social withdrawal from friends or favorite activities.

Begging or stealing money or necessary supplies.

Emotional neediness

Displaying an extreme, demanding need for attention or affection from adults.

Being overly compliant or submissive to a degree that is uncharacteristic.
