The Yale-Brown Obsession-Compulsion Scale (CY-BOCS) is a structured interview that provides an assessment of the severity of obsessive-compulsive symptoms unbiased by the presence or absence of a particular type of obsession or compulsion.

The Spence Children's Anxiety Scale (SCAS) is a 44-item self-report questionnaire. Each item is rated on a 4-point Likert scale, from 0 (never) to 3 (always). No time period is specified for the scope of the questions.

Six of the 44 items are positive items intended to limit the tendency to respond negatively; they are not included in the overall score.

The overall score, obtained by adding all 38 items, ranges from 0 to 144. The questionnaire identifies six dimensions of anxiety: Panic Attack and Agoraphobia, Separation Anxiety, Fear of Physical Injury, Social Phobia, OCD, and Generalized Anxiety Disorder.

The Children's Depression Rating Scale - Revised (CDRS) is a revised version of a questionnaire originally derived from the Hamilton Rating Scale for Depression. The total score is an index of the intensity of depressive symptomatology in children aged 6 to 12 years. It is a 17-item, self-assessment tool, completed by a clinician based on a non-directive interview with the child, and supplemented or corrected, based on clinical judgment, with additional information from the family or teachers.

The UCLA Child/Adolescent Posttraumatic Stress Disorder Reaction Index was designed for use with school-aged children and adolescents. The DSM-5 version is a semi-structured interview with a clinician that assesses a child's trauma history and the full range of DSM-5 symptoms and diagnostic criteria for posttraumatic stress disorder. This measure consists of several parts: an assessment of different types of trauma, a DSM-5 posttraumatic stress disorder symptom scale including dissociative symptoms, and an assessment of distress and impairment.

The ADHD Rating Scale is a specific assessment tool for ADHD.
