Evaluating the Impact of Reining in Anxiety

This will be measured by the Generalized Anxiety Disorder-2 (GAD-2) questionnaire which consists of two items that assesses the presence of anxiety. Items are summed, and a score of 3 or higher is usually indicative of further evaluation.

The Children's Global Assessment Scale (CGAS). The child is given a single score between 1- 100, based on an assessment of a range of aspects related to the child's psychological and social functioning. The score places them in one of ten categories, ranging from "extremely impaired" (1-10) to "doing very well (91-100).

This will be measured by the Children's Sadness Management Scale (CSMS) which was developed to assess children's inhibition, dysregulated expression, and coping with sadness experience and expression developed to assess three dimensions of sadness management. Children respond to 12 items on a 3-point scale (1: hardly ever, 2: sometimes, 3: often). This scale was modified to focus on dealing with anxiety rather than sadness.

This is measured by the Emotion Regulation Checklist (ERC- full scale). The ERC is a 24-item questionnaire using a 4-point Likert scale that was used to assess parents' perceptions of their child's ability to manage emotion. This measure yields two empirically derived scales: (a) Emotion Regulation that assesses situationally appropriate affective displays and emotional self-awareness and (b) Lability/Negativity, which measures mood lability and culturally inappropriate affective displays. two additional questions were added about how long it takes children to regulate.

This is measured by the Self-Efficacy Questionnaire for Children, emotional self-efficacy subscale (SEQ-C). The scale was modified the SEQ-C, which has 24 questions regarding 3 domains of self-efficacy, to utilize only the eight emotional self-efficacy items to assess parent's beliefs regarding their children's competence in controlling negative emotions. Items are scored using a 5- point Likert scale ranging from "not at all (1)" to "very well (5)." Higher scores indicate greater self-efficacy. Parents/caregivers of youth enrolled in the study completed this measure both pre and post-intervention.

Knowledge of anxiety scale was developed by the study's researchers to assess the knowledge of anxiety from child and parent before and after the intervention, attempting to measure what has been learned in psychoeducation about anxiety.

Traumatic events will be measured by the CYW Adverse Childhood Experiences Questionnaire (ACE-Q) Child, to be completed by parent/caregiver. The measure involves a list of statements of traumatic events in two sections, and parents adding up the number of statements that apply to their child. Section 1 has 10 statements, and Section 2 has 7 statements.

Modified Center for the Study of Animal Wellness Scale will be used to gauge how the children feel about the horse. Attachment to the horse will be measured by the modified Center for the Study of Animal Wellness CSAW Pet B, which is a 27-item self-report measure of children's attachment. The measure presents three descriptions of feelings/perceptions about the child's relationship to the horse.

Caregiver Satisfaction Questionnaire delivered at posttest will assess the caregiver's satisfaction with they and their child's involvement in the program

A Satisfaction Questionnaire administered at posttest will assess the instructors' satisfaction with training and delivery of the intervention.
