Which behavior classification would include difficulty staying on task and being easily distracted?

The classification that includes difficulty staying on task and being easily distracted is Attention Deficit Hyperactivity Disorder (ADHD). This disorder is characterized by a persistent pattern of inattention and/or hyperactivity-impulsivity that interferes with functioning or development. Individuals with ADHD often struggle to focus, follow through on tasks, and can easily become distracted by external stimuli or irrelevant information. These symptoms can affect their academic performance, social interactions, and daily activities, as they may find it challenging to maintain attention on a single task.

On the other hand, Oppositional Defiant Disorder primarily involves a pattern of angry or irritable moods, argumentative behavior, and vindictiveness, rather than issues with attention and focus. Conduct Disorder is focused on more serious behavioral issues, including aggression towards people or animals, destruction of property, deceitfulness, or serious violations of rules. Autism Spectrum Disorder encompasses a range of social communication challenges and behaviors, but the defining characteristics do not typically center around inattention or distractibility in the same way that ADHD does.
