Children diagnosed with Autism Spectrum Disorder (ASD) often have increased levels of stress, leading to dysregulated production of cortisol. Elevated levels of cortisol have numerous known adverse health consequences, and therefore, interventions should be established to help attenuate cortisol production. As judo combines physical activity and mindfulness practice, it may aid in stress reduction and decreased levels of cortisol. Purpose: To examine the effects of a 10-week judo program on...
Show moreChildren diagnosed with Autism Spectrum Disorder (ASD) often have increased levels of stress, leading to dysregulated production of cortisol. Elevated levels of cortisol have numerous known adverse health consequences, and therefore, interventions should be established to help attenuate cortisol production. As judo combines physical activity and mindfulness practice, it may aid in stress reduction and decreased levels of cortisol. Purpose: To examine the effects of a 10-week judo program on stress reactions and salivary cortisol levels in youth with ASD. Methods: 20 children with ASD participated in the 10-week judo program. Changes in acute (before and after one judo session) and chronic salivary cortisol levels were assessed at baseline and post intervention. Parents of participants were asked to complete the Stress Survey Schedule (SSS) to determine severity of stress reactions. The SSS consists of 10 subscales: changes, anticipation, unpleasant, positives, food related, rituals, social/environmental, sensory/personal, fears, and life stressors. Sleep quality was assessed via Actigraph GT9X accelerometers over a 7-day period at baseline and post-intervention. Paired samples t-tests were used to determine differences SSS pre/post-intervention. Repeated measures ANOVA was conducted to determine differences and in cortisol levels before and after one judo session and pre and post-intervention. Spearman correlations were used to determine correlations between sleep quality and subscales of the SSS. Results: Although not statistically significant, a trend was noted indicating a decrease in cortisol levels following one judo session (p=.057). Nonsignificant reductions in the subscales (")changes (p=.14)(") and (")unpleasant (p=.12)(") of the SSS were also observed. Conclusion: Acute changes in cortisol levels may be seen following one session of judo. Subscales of parent-reported questionnaire may also show improvements following 10 weeks of participation in a judo program.

Show moreThe concept of quantifying animal welfare has received much discussion, in various industries such as agriculture, laboratory, and zoological facilities. Behavioral, physical, and physiological indicators of welfare have previously been used to assess animal welfare; each having advantages and disadvantages, ranging from the practicality of data collection, to the validity of the data and how it is interpreted. Concurrent assessment of multiple measures is a more robust way to examine animal welfare, which utilizes the advantages of each measure, and provides additional information on which to base conclusions and animal care management decisions. This study used measures of behavior and urinary cortisol to examine the potential stress response of a captive gorilla group to short-term space restriction associated with temporary confinement to indoor housing facilities. The study duration was three months; one month of baseline data collection, one month of indoor restriction, and one month of monitoring post-restriction. All-occurrences of selected behaviors were collected, with an emphasis on social and stress-related behaviors, and urine samples were collected daily from a sub-set of the group. A urinary cortisol metabolite enzyme immunoassay was validated and used to monitor adrenal activity in gorillas. Measured cortisol increases in response to a known stressor (medical illness) provided a physical validation of the cortisol EIA and established biological relevance of the assay system. No significant differences in social behaviors (aggression, affiliation) or stereotypic behaviors were observed. Significant (p<0.05) increases in cortisol concentration were measured, suggesting that the gorillas were responding to a stressor during the study period. The observed cortisol increase was not likely to have been caused exclusively by the temporary indoor confinement. Potential additional causes of increased adrenal activity during the study included: presence of the observer and novelty of re-landscaped outdoor enclosure. While the increases in cortisol concentration demonstrate an observed stress response, the magnitude of this stressor, and thus the degree of the stress response, was minor. The stress experienced was not significant enough to alter the normal biological function of the gorillas, and thus, can be considered negligible. The gorillas' ability to effectively deal with this expected stressor may have been enhanced by the additional enrichment provided to the gorillas during their indoor confinement. Gorillas were provided with additional browse, more enrichment items, additional training sessions, and increased keeper interaction while they remained indoors. These animal care and management techniques may have buffered the predicted negative impact on animal welfare due to increases in stress by providing stimulating novelty in the gorillas' indoor environment.

Show moreAnxiety, depression, and stress are three of the most common experiences that impact college student functioning and academic achievement. At least one in six college students struggle with anxiety, increasing risk for developing depressive symptoms or disorders that further impact wellness. However, as mental health concerns increase across campuses, universities are not equipped to meet the demand of mental health support for college students. Neurofeedback (NF) training presents as an innovative intervention to treat anxiety, depression, and stress as it is designed to regulate brain processes in an effort to increase more effective brain functioning. A quasi-experimental, nonequivalent control group design was utilized to determine differences between treatment group and waitlist control group participants' anxiety, stress, and depression scores at four time points as measured by the: (a) Beck Anxiety Inventory [BAI] (Beck, Epstein, Brown, (&) Steer, 1988); (b) Beck Depression Inventory, Second Edition [BDI-II] (Beck, Steer, (&) Brown, 1996); (c) Perceived Stress Scale [PSS] (Cohen, Kamarck, (&) Mermelstein, 1983); and (d) Social Anxiety Thought questionnaire [SAT] (Hartman, 1984). Furthermore, cortisol testing was used through assessment of saliva samples using Salimetrics Enzyme-Linked Immunosorbent Assay (ELISA). Key findings for the current investigation include: (a) a marginally significant (p = .051) difference between treatment group and control group participants' PSS (partial ?2 = .093), BDI-II (partial ?2 = .089), and SAT (partial ?2 = .052) scores over time; (b) no significance difference among participant demographics between treatment group and control group assessment scores over time; (c) no significance between treatment group and control group assessment scores and salivary cortisol levels over time; and (d) a negative relationship between the control group participants' salivary cortisol levels at pre-test on the BAI, PSS, and SAT. Finally, results are compared to previous studies. Limitations and implications as well as areas for future research are explored.

Show moreAddictive disorders/substance use disorders (SUDS) affect almost everyone in the United States, either directly or indirectly. The cost of substance abuse to the social and economic structure in the United States is huge. Anxiety is one of the most frequently mentioned symptoms which lead to relapse during the early weeks of recovery due to neurohormonal changes in the limbic system as well as cortisol production which occur during this time. Present research in the treatment of anxiety in substance abuse and long term recovery is focused on genetics and pharmaceuticals, however most pharmaceuticals produce sedation. Additional therapies in early recovery, which decrease the symptoms of anxiety while enhancing cognitive ability to learn and apply coping skills, are needed.Purpose: The purpose of this dissertation was to identify the natural degradation of anxiety symptoms occurring during the first few weeks following detox from alcohol or opiates. To identify non pharmacological methods in use to decrease anxiety symptoms during this period, and then examine whether treatment with Cranial Electrotherapy Stimulation (CES) would enhance the degradation of anxiety symptoms. Methods and Results: The initial prospective study of 53 men in residential treatment, measured anxiety on entry, 30 and 60 days. The results found that increased anxiety measured prior to a participant leaving against medical advice was more significant than increased anxiety measured on admission. The follow-on pilot study in the same residential program was a double-blind experimental study using CES with active and placebo CES units loaned from the manufacturer. The intervention was conducted during the first 3 weeks of opiate/alcohol abstinence; a period identified when anxiety peaks, and dropout rate is high. There were 29 men in the experimental group and 31 in the placebo group. Salivary cortisol and state anxiety were measured on the first and final day of CES treatment. Anxiety was also measured at study enrollment and at 30 days when study enrollment was terminated. The results were statistically inconclusive as both the placebo and CES (experimental) groups trended downward; however the trend was greater in the CES group. Discussion/Implications: Anxiety was identified as a significant factor in leaving treatment early. Cranial Electrotherapy Stimulation appears to decrease anxiety in non-substance abusing populations. However, these finding were not supported in this substance abusing population during the first month of recovery. Although CES appeared to be the most promising alternative therapy, more research is needed in the use of this and other emerging therapies for the treatment of anxiety symptoms during this early recovery period.

Show moreHair has become an invaluable resource in forensic, clinical, and bioarchaeological research. The unique interaction between the growing hair fiber, the hair follicle, and the endocrine system inundates the growing hair fiber with an incremental record of many of the discreet physiological processes of the body. Recently, a novel study by Webb et al. (2010) demonstrated that endogenous records of cortisol, the (")stress hormone("), are capable of being extracted from archaeological human hair through a modified enzyme-linked immunosorbent assay (ELISA) technique, thus providing insight into the (")invisible(") stress experiences of an individual that would otherwise not be detectable through skeletal analysis. The present study seeks to apply this novel ELISA technique to archaeological hair to determine whether endogenous patterns of secretion are detectable for the steroid reproductive hormones estradiol and testosterone. Here, hair from 10 individuals from the Kellis 2 cemetery in the Dakhleh Oasis, Egypt is analyzed for endogenous concentrations of the steroid hormones cortisol, estradiol, and testosterone. A control sample consisting of hair from 10 modern cadavers is also assessed for each hormone to ensure method efficacy. Cortisol, estradiol, and testosterone were successfully identified in all 10 archaeological individuals and in each of the 10 individuals in the modern control group. Results revealed that archaeological preservation of each hormone was favorable, and incremental patterning of each hormone seem to reflect endogenous hormone secretion in life. Values for cortisol, estradiol in pre-menopausal females, and testosterone extracted from the archaeological and modern control samples fall within reference values taken from archaeological and clinical research; however, estradiol values for males and postmenopausal females exceeded projected reference values. Explorations for variables which could contribute to discrepancies between reported and observed estradiol values are provided, along with two case studies on female individuals from the archaeological sample. The results of this study demonstrate that steroid reproductive hormones can be preserved in archaeological human hair, and that these hormones can be analyzed to create additional lines of inquiry into bioarcheological studies of ancient health and fertility.
