Which of the following is NOT a characteristic of emotional disturbance?

The characteristic of emotional disturbance that is not applicable is a general pervasive mood of happiness. Emotional disturbance encompasses significant difficulties in emotional regulation and behavior, which can lead to challenges in learning, maintaining relationships, and managing emotional responses. A pervasive mood of happiness does not align with the struggles typically seen in individuals with emotional disturbances, who might often experience sadness, anxiety, or anger. Consequently, a mood characterized by happiness would contradict the defining features of emotional disturbance, highlighting why this option is correct.
