Findings from Taylor & Jason (2001) study

1. Findings from Taylor & Jason (2001) study Taylor, R.R. & Jason, L.A. (2001). Sexual abuse, physical abuse, chronic fatigue, and chronic fatigue syndrome: A community-based study. Journal of Nervous and Mental Disease, 189, 709-715.

2. Objectives of Our Study In a random community sample unbiased by help-seeking behavior or self-selection… • Do rates of abuse vary among individuals with different conditions involving chronic fatigue and healthy controls? • Do individuals with CFS demonstrate an increased likelihood to report histories of childhood sexual, physical, and death threat abuse?

3. Methods • A random community sample of 18,675 adults was screened for CFS symptoms. • A subset of participants with chronic fatigue and healthy controls underwent full psychiatric and medical evaluation, which included a structured interview assessing childhood and adulthood history of sexual abuse, physical abuse, and death threat.

4. Methods Diagnoses from Physician Review Panel • 32 chronic fatigue syndrome (CFS) • 45 idiopathic chronic fatigue (ICF) • 56 psychiatrically explained chronic fatigue (CF-Explained-Psychiatric) • 33 medically explained chronic fatigue (CF-Explained-Medical) • 47 controls

5. Question 1 Do rates of abuse vary among healthy controls and medically diagnosed fatigue groups? • Multinomial logistic regression was used to examine the relationship between abuse history and chronic fatigue group outcomes while controlling for the effects of sociodemographic variables.

6. Results Childhood Sexual Abuse significantly predicted diagnoses of: • idiopathic chronic fatigue • chronic fatigue explained - psychiatric • chronic fatigue explained - medical None of the abuse history types significantly predicted a diagnosis of chronic fatigue syndrome.

7. Results Childhood Sexual Abuse CFSICFCF-PsychCF-MedControl 16.1% 34.1%** 28.8%* 21.2%* 2.2%

8. Question 2 Do individuals with CFS demonstrate an increased likelihood to report histories of childhood abuse? • A one-way Chi-square test was performed within the CFS group comparing presence versus absence of childhood sexual, physical, and death threat abuse.

9. CFS Group Results PresentAbsent X2 Sexual Abuse 16.1% 83.9% 14.23** Physical Abuse 29.0% 71.0% 5.45* Death Threat 6.5% 93.5% 23.52**

10. Conclusions • Taken together, findings from medical samples (Doyle et al., 1999; Tiersky et al., 1998) and this random epidemiological sample indicate that histories of childhood sexual, physical, or death threat abuse are not implicated in the etiology of chronic fatigue syndrome. • Other risk factors may be involved in the etiology of CFS, and further research is necessary to explore alternative hypotheses.

11. Impairment • The ADA definition of impairment is: 1. A major physical or mental impairment that substantially limits one or more major life activities. 2. Having a record of such impairment, such as educational, medical, or employment records. 3. Being “regarded” as having such an impairment.

12. What does “substantially limits a major life activity” mean? • Being unable to perform one of the following major life activities: • breathing, walking, sitting, standing, lifting, reaching, performing manual tasks, caring for oneself, learning, working, etc.

13. CFS Physical and Mental Impairments • A person with CFS may have a physical impairment because CFS substantially limits her ability to stand, walk, lift, care for herself, or breathe. • A person with CFS may have a mental impairment because CFS substantially limits her ability to learn, concentrate, and retain new information.

14. Social Security Administration • In April, 1999, SSA issued new regulations defining medically determinable impairment requirements for CFS.
