Analysis

The Strengths and Difficulties Questionnaire – Self-Completion (SDQ-SC-25) is a version of the SDQ intended for self-assessment by the participants themselves, typically adolescents or adults. The purpose is to evaluate emotional and psychological difficulties as well as strengths from the perspective of the individual completing the questionnaire.

Objective

The primary goal of the SDQ-SC is to enable participants to evaluate their own emotional states, behaviors, and social interactions.

Scoring

The SDQ-SC consists of 25 questions, divided into 5 subcategories, with each subcategory containing 5 questions. The questions are rated on a Likert scale of 3 or 4 points (ranging from “never” to “very often”). The subcategories include Emotional Difficulties, Behavioral Difficulties, Social Difficulties, Strengths, and Overall Difficulty.
