Strengths and Difficulties – Offspring
Abstract: The Strengths and Difficulties Questionnaire (SDQ) is a brief 25-item behavioral screening questionnaire capturing positive and negative attributes of children age 2 to 17 year olds. Compared with well-established Rutter questionnaires, the SDQ has high validity and reliability (Goodman 1997). Furthermore, the SDQ offers the following additional advantages: a focus on strengths as well as difficulties; better coverage of inattention, peer relationships, and prosocial behavior; a shorter format; and a single form suitable for both parents and teachers, perhaps thereby increasing parent-teacher correlations (Goodman 1997). Four of the subscales on the parent SDQ. Alphas were generally higher for male children and for low parental education level (Mieloo 2012). For the Fast Track Project, participants completed the Strengths and Difficulties Questionnaire for each of their children ages 2 to 17 years old.
