Eficácia Preliminar da Terapia Ocupacional Integrando Cavalos na Auto-regulação em Jovens com Autismo
Eficácia preliminar da terapia ocupacional integrando cavalos na autorregulação em jovens com transtorno do espectro autista
The goal of this clinical trial is to learn about occupational therapy integrating horses for autistic youth. The main questions it aims to answer are:
- Does occupational therapy integrating horses improve self-regulation in autistic youth
- Does occupational therapy integrating horses affect salivary cortisol and alpha-amylase
Participants will receive 10 weeks of occupational therapy, and will be asked to provide saliva samples each week.
Researchers will compare occupational therapy integrating horses to occupational therapy in a clinic to see if integrating horses affects self-regulation.

Descrição detalhada
The goal of this project is to quantify the unique benefits of integrating horses in occupational therapy compared to occupational therapy in a clinic (i.e., OTEE HORS vs. OT Clinic) for improving self-regulation in youth with ASD.
To address both aims we will randomize 64 youth with ASD ages 6-11 years old to OTEE HORS or OT clinic.
Specific Aim 1: Examine the preliminary efficacy of OTEE HORS compared to OT Clinic on self-regulation. Hypotheses: The OTEE HORS group will demonstrate significantly larger improvements than the OT Clinic group in five domains of self-regulation (hyperactivity [primary], irritability, emotional reactivity, dysphoria, and individual goal attainment).
Specific Aim 2: Identify potential physiological mechanisms that explain how integration of horses in occupational therapy impacts self-regulation in youth with ASD. Hypotheses 2A & B: The OTEE HORS group will demonstrate significantly larger decreases in salivary cortisol after each 60-minute therapy session and after the 10-week treatment course in comparison to the OT Clinic group. Hypotheses 2C & 2D: The OTEE HORS group will demonstrate significantly greater increases in salivary alpha-amylase after each 60-minute therapy session, and significantly greater decreases in salivary alpha-amylase over time as measured after the 10-week treatment course in comparison to the OT Clinic group. Exploratory Hypothesis 2E: Changes in physiological measures will significantly correlate with changes in Aim 1 behavioral measures.

Descrição da medida |
Prazo |
|---|---|---|
|
Change in Hyperactivity
Prazo: Week 1 & Week 10
|
The Hyperactivity subscale of the Aberrant Behavior Checklist, Second Edition (ABC-2) measures parent/caregiver-reported hyperactive and impulsive behaviors, including excessive activity, impulsivity, and difficulty remaining still or attending. The subscale consists of 16 items, with total scores ranging from 0-48. Higher scores indicate greater hyperactivity and more severe behavioral difficulties, while lower scores indicate less hyperactivity and better behavioral functioning. Item scores are summed to produce the subscale score. |

Change in Irritability
Prazo: Week 1 & Week 10
|
The Irritability subscale of the Aberrant Behavior Checklist, Second Edition (ABC-2) measures behaviors associated with irritability, including aggression, self-injury, tantrums, and mood instability. The subscale consists of 15 items, with total scores ranging from 0-45. Higher scores indicate greater irritability and more severe behavioral difficulties, while lower scores indicate less irritability and better behavioral functioning. Items are rated based on the presence and severity of behaviors, and item scores are summed to produce the subscale score. |
Week 1 & Week 10
|
|
Change in Emotional Reactivity
Prazo: Week 1 & Week 10
|
The Emotional Reactivity subscale of the Emotion Dysregulation Inventory (EDI) measures the tendency to experience intense, rapidly escalating, and prolonged negative emotional responses. T-scores are standardized scores derived from the raw Emotional Reactivity score and have a mean of 50 and standard deviation of 10 in the normative sample. Higher T-scores indicate greater emotional reactivity and more severe emotion dysregulation, while lower T-scores indicate less emotional reactivity and better emotional regulation. |
Week 1 & Week 10
|
|
Change in Dysphoria
Prazo: Week 1 & Week 10
|
The Dysphoria subscale of the Emotion Dysregulation Inventory (EDI) measures symptoms of negative mood, including sadness, hopelessness, and emotional distress. T-scores are standardized scores derived from the raw Dysphoria score and have a mean of 50 and standard deviation of 10 in the normative sample. Higher T-scores indicate greater dysphoria and more severe negative mood symptoms, while lower T-scores indicate less dysphoria and better emotional well-being. |

Descrição do plano IPD
De-identified data will be shared in an appropriate data repository, such as the "Data and Specimen Hub" (DASH) or the "National Database for Autism Research" (NDAR). Data will be shared no later than the acceptance for publication of the main findings from the final dataset. Salimetrics will discard saliva samples after testing, and therefore saliva samples will not be available for sharing.
Prazo de Compartilhamento de IPD
We will share in an appropriate data repository indefinitely, no later than the acceptance for publication of the main findings from the final dataset
