Which behavior in school-age years may indicate characteristics of antisocial personality disorder?

Mutilating the neighbor's cat is indicative of a serious behavioral issue that aligns with traits often associated with antisocial personality disorder. Antisocial personality disorder is characterized by a persistent pattern of disregard for the rights of others and societal norms, often manifested in behaviors that are harmful or aggressive. Engaging in acts of cruelty towards animals is a common indicator of antisocial behavior in children, which can escalate to more severe offenses as they grow older.

This behavior is not merely a phase; it reflects a lack of empathy and a potential for violent tendencies, which are crucial components of antisocial behavior. In contrast, the other options, such as playing alone frequently or exhibiting tantrums, may stem from various developmental, social, or emotional issues but do not necessarily indicate the predisposition for antisocial personality traits. Additionally, having few friends might suggest social difficulties or shyness rather than an inherent disregard for the well-being of others. Therefore, mutilating an animal is a clear red flag that warrants further evaluation and intervention regarding the child's mental health and social development.
