The Parenting Scale (SC) is a 7-point Likert-scale 30-item questionnaire that measures the similarities and differences in how the parents parent. The questions ask parents simple hypotheticals to see how they would react to different behavior problems. The parenting scale’s 30 questions can be found here. The scale measures the parents on three subscales: laxness, overreactivity and hostile parenting, although in the Swedish context, only laxness and overreactivity have been found to be reliable (see Salari, Terreros, & Sarkadi, 2012). Laxness refers to a parents’ inconsistent or permissive parenting, while overreactivity refers to a parents’ harsh or punitive parenting. Hostile parenting refers to the extent to which a parent hits, curses or insults their child.
