Final answer:
The total difficulties score range for the SDQ is 0-40.
Step-by-step explanation:
The score range for total difficulties in the Strengths and Difficulties Questionnaire (SDQ) is 0-40. The SDQ is a behavioral screening questionnaire used to evaluate 25 attributes, some positive and others negative. These are divided into 5 scales, each scale encompassing 5 items, and include emotional symptoms, conduct problems, hyperactivity/inattention, peer relationship problems, and pro-social behavior. The total score of the 20 items (excluding the pro-social scale) generates a total difficulty score that helps in the assessment of children's and adolescents' mental health.
