Which of the following is a risk factor for childhood onset conduct disorder?

A. Living in a safe and supportive neighborhood is considered a protective factor for childhood development. Children who grow up in environments where they feel safe and have access to community resources, recreational activities, and supportive peers are less likely to engage in antisocial or aggressive behaviors. Such an environment promotes positive socialization and reduces exposure to delinquent influences, which decreases the risk for childhood-onset conduct disorder. B. Strong parental involvement in education is another protective factor. When parents actively participate in their child’s schooling—attending parent-teacher meetings, helping with homework, and encouraging positive academic behaviors—children are more likely to develop self-regulation, social skills, and respect for authority. These factors mitigate the likelihood of developing the aggressive, defiant, and rule-breaking behaviors seen in conduct disorder. C. High levels of family socioeconomic stability provide consistency in housing, nutrition, healthcare, and educational opportunities. Stable families tend to have better access to mental health resources and structured routines, which decrease stress and reduce the risk for behavioral disorders. Therefore, socioeconomic stability is protective rather than a risk factor. D. Parental rejection or neglect is correct. childhood-onset conduct disorder often develops in the context of dysfunctional family dynamics. Children who experience emotional neglect, lack of supervision, inconsistent or harsh discipline, or outright rejection from caregivers may feel unsupported and develop maladaptive coping mechanisms. This can manifest as aggression toward peers, deceitfulness, theft, vandalism, or other antisocial behaviors. Research shows that family factors, especially negative parenting and emotional neglect, are among the strongest predictors of early-onset conduct disorder, particularly when combined with other risk factors such as comorbid ADHD or exposure to community violence.
