Magnetic resonance imaging |
This is exploratory outcome. Magnetic resonance imaging (MRI) is used to obtain images of the patients' brains before and after treatment and the scanning consists of both structural and functional scans. From the functional scans response-inhibition-related and switch-related activity during Stop Signal Task performance and Task Switching performance is examined. |

Family Accommodation Scale |
This is exploratory outcome showing family factors. Family Accommodation Scale (FAS): a 13-item parent-report measure designed to assess accommodation of a child's OCD-related behaviors over the previous month. In an effort to assess multiple dimensions to accommodations (rather than one in isolation), items are anchored with respect to either frequency or magnitude utilizing a 5-pt Likert scale ranging from 0 (Never) to 4 (Daily) with higher scores indicating greater parental accommodation. |

Family Environment Scale |
This is exploratory outcome showing family factors. Family Environment Scale (FES)is composed of 90 items and 10 subscales that measure actual, preferred, and expected family social environments. The 10 subscales assess three dimensions: relationship dimensions, personal growth (or goal orientation) dimensions, and system maintenance dimensions. There are three FES forms (real, ideal, and expectations); only the FES real form will be used, which examines a family member's perception of the family as it is. The scale ranges from 10 to 40, with a score of 10 being representative of no family conflict and a score of 40 being representative of the greatest magnitude of family conflict. Therefore, a decrease in score represents a decrease in self-reported family conflict. |

Parental Stress Scale |
This is exploratory outcome showing family factors. Parental Stress Scale (PSS)measures parental stress in the parental relationship and consists of 18 items. The parent answers different statements about his or her relationship to the child by scoring each item on a five-point Likert-scale (1-5), 5 representing the highest amount of agreement with the statement and 1 representing the highest amount of dis-agreement. The positively formulated items are scored in reverse. PSS is thus scored on a scale from 18 to 90, where higher scores reflect greater stress. |

Child Obsessive-Compulsive Impact Scale |
This is exploratory clinical outcome.Child Obsessive-Compulsive Impact Scale (COIS) is a 33-item parent-report and self-report questionnaire that assesses OCD-related impairment in various areas of the child's life, including school, social, and home/family activities. For each item, the respondent rates the child's level of impairment on a 4-point Likert scale from 0 (not at all) to 3 (very much). The total score (0-99) is the sum of the item scores. Higher scores reflect more severe impairment. |

Clinical Global Impression Severity and Clinical Global Impression Improvement Scale |
This is exploratory clinical outcome. Clinical Global Impression Severity and Clinical Global Impression Improvement Scale (CGI-I and CGI-S) measure symptom severity, treatment response, and the efficacy of treatments in treatment studies of patients with mental disorders. Therefore higher scores indicate a worse mental state of the patient. The CGI is rated on a 7-point scale, with the severity of illness scale using a range of responses from 1 (normal) through to 7 (amongst the most severely ill patients). CGI-I scores range from 1 (very much improved) through to 7 (very much worse). |

Toronto Obsessive-Compulsive Rating Scale |
This is an exploratory clinical outcome. Toronto Obsessive-Compulsive Rating Scale (TOCS) is a quantitative and multidimensional measure of Obsessive-Compulsive traits in children and adolescents. Questionnaire with 21 items, and each item is scored on a 7-point likert scale from -3 to 3. Dimension scores ranges from -3 to 3. The total scale ranges from -63 to 63. Higher values represents worse outcome. |

This is exploratory cognition outcome. Working memory capacity assessed by Spatial Working Memory test. It requires retention and manipulation of visuospatial information. This self-ordered test has notable executive function demands and provides a measure of strategy as well as working memory errors. Reaction time and accuracy. Low reaction time combined with high accuracy represents better memory capacity. |

Motor skills |
This is an exploratory cognition outcome. Motor skills assessed with Purdue Pegboard test. It controls for potential effects of differences in motor skills on performance on other tasks in the battery. Test is a rectangular board with 2 sets of 25 holes running vertically and 4 concave cups at the top. Small metal pegs are placed in the cup on the side being tested, with subjects asked to remove the pegs and place them vertically in the holes as rapidly as possible. The number of pegs placed in 30 seconds is scored. More accurate placed pegs represent better motor skills. |
