2 Clinical Trials for Various Conditions
The overall purpose of this study is to determine feasibility and preliminary efficacy of pet therapy, or human-animal interactions (HAI), for children (5-12 years of age) with or at risk for LD. Children among 4 reading groups will be randomly assigned to a HAI intervention or control group. The 2 HAI intervention reading groups will receive visits from a registered canine team during children's small group reading sessions twice a week over 12 weeks. The 2 control reading groups will receive care as usual and offered a 1-time visit from the dog at the end of the study (after T3 completed). Two weeks of initial work will focus on preliminary modifications to the protocol. Parents will complete electronic measures of psychological outcomes (child depression, anxiety, QOL) via REDCap at baseline (T1), 2 weeks post-baseline (T2), and 12 weeks post-baseline (T3). The investigators will obtain copies of reading assessments already conducted by the teachers at T1 and T3. Children's salivary cortisol will be obtained from participants in the intervention groups at T1, T2, and T3. Children and their parents will complete concluding interviews at study end (T3) to further inform what they liked and did not like about the intervention. Results of the proposed study will provide critical data for a future full-scale randomized clinical trial (R01) to examine the impact of HAI on psychological, physiological, and reading outcomes in children with or at risk for LD.
Posttraumatic stress disorder (PTSD) among military Veterans is a critical public health concern. Veteran suicide rates exceed those of the general population, with the disorder creating a mental health challenge that is costly and debilitating. The majority of Veterans with PTSD also have comorbid mental health diagnoses, such as generalized anxiety disorder, substance abuse disorder, and major depression. The treatment of Veteran PTSD and comorbid disorders represents an important therapeutic and rehabilitation problem. The disorder is complex and difficult to treat, with high treatment dropout and nonresponse rates spurring some Veterans to seek complementary integrative health strategies. One promising complementary strategy is the provision of a trained service dog. Initial evidence across multiple research groups highlights service dogs as a promising complement to evidence-based practices that can offer short-term improvements. However, the long-term effectiveness, mechanisms of action, and moderators of efficacy remain largely unknown. Thus, the overarching objective of this proposal is to understand how, why, and for whom PTSD service dogs are most effective. To address this objective, the present project will assess the longitudinal efficacy and dose-response curve of service dogs for Veteran PTSD symptomology and psychosocial functioning. The research design will consist of a two-arm, randomized clinical trial (RCT) with longitudinal assessments over a period of 15 months. Results are expected to elucidate the clinical impact of service dogs for military Veterans with PTSD, as well as the biobehavioral mechanisms of action and characteristics that moderate efficacy. These outcomes will support the long-term goal of accelerating complementary and integrative health interventions, through optimized and evidence-based service dog interventions. As such, this project will further advance the scientific understanding of human-animal interactions for psychosocial health.
