The purpose of this study is to test the effects of a videotelephone-delivered patient-partner dual-focused cognitive behavioral stress management intervention on chronic fatigue syndrome (CFS) symptoms and related psychosocial and neuroimmune processes in patients diagnosed with chronic fatigue syndrome. Study tests the hypothesis that videophone-delivered patient-partner cognitive behavioral stress management (T-PP-CBSM) intervention improves patient CFS symptoms relative to a videophone-delivered patient-partner Health Information (PP-T- HI) condition.
The study tests the effects of a 10-week patient-partner focused videophone-delivered cognitive behavioral stress management intervention (T-PP-CBSM) intervention (relaxation, stress awareness, cognitive restructuring, coping skills training, interpersonal skills training) versus a time-attention-matched 10-week patient-partner based videophone-delivered health information (T-PP-HI) (health behavior education on nutrition, sleep and other factors) in men and women with chronic fatigue syndrome (CFS) and their partners. The study evaluates the effects of T-PP-CBSM vs T-PP-HI on patient CFS symptoms, neuroimmune processes--diurnal cortisol regulation and immune regulation (pro-inflammatory:anti-inflammatory cytokine ratio (\[IL-1β + IL-6 + TNF-α\]:\[IL-13 + IL-10\])-and psychosocial functioning at 5 months and 9 months after intervention.

Changes in Frequency and Severity of CDC-based CFS Symptoms
Changes in the average frequency and average severity ratings of CFS symptoms as assessed by the CDC Symptom Inventory. Participants rated the frequency (1: A little of the time to 5: All of the time) and severity (1: Very mild to 5: Very severe) of individual CFS symptoms. Greater units on the scale indicate greater symptom frequency or severity. The outcome measure was calculated as a set of two composite scores: 1) Average Symptom Frequency, reflecting an aggregated average of frequency across all symptoms, and 2) Average Symptom Severity, reflecting an aggregated average of severity across all symptoms. Change scores are expressed and calculated as Follow-Up minus Baseline scores for average symptom frequency and average symptom severity.
Time frame: baseline and 5 and 9 month post-intervention follow-up
Changes in a Single Composite Product of Average Frequency and Severity Scores of CDC-based CFS Symptoms
Changes in the composite product of average frequency and severity scores of CDC-based CFS symptoms assessed by the CDC Symptom Inventory. Participants rated the frequency (1: A little of the time to 5: All of the time) and severity (1: Very mild to 5: Very severe) of individual CFS symptoms. Greater units on the scale indicate greater symptom frequency or severity. The composite outcome measure was calculated as the product of Average Symptom Frequency and Average Symptom Severity. Change scores are expressed and calculated as Follow-Up minus Baseline scores for the composite product score.
Time frame: baseline and 5 and 9 months post-intervention follow-up
Changes in Neuroimmune Functioning Measured by Change in Averaged (2-day) Di-urnal Slope of Salivary Cortisol.
Changes in salivary cortisol diurnal pattern is measured to determine changes in neuroimmune function. Salivary cortisol diurnal pattern is computed as the natural log of the average within-day slope of change over the 2-day collection period. This measurement is made at baseline, 5 month follow-up and 9 month follow-up. Outcomes are expressed as change in Cortisol Diurnal Pattern (natural log of average 2-day slope values) and expressed and calculated as Follow-Up minus Baseline values (using the natural log of average 2-day slope values).

Changes in Neuroimmune Functioning Measured by Pro-Inflammatory Cytokines
Serum samples were collected to measure the pro-inflammatory cytokines Interleukin (IL)-1a, IL-6 and Tumor Necrosis Factor (TNF)-a for neuroimmune function. Units of measure are raw concentration expressed picograms per milliliter (pg/mL). Change values are expressed and calculated as Follow-Up minus Baseline values (using raw values).
Time frame: Baseline, 5 months, 9 months
Changes in Neuroimmune Functioning Measured by Anti-inflammatory Cytokines
Serum samples were collected to measure the anti-inflammatory cytokines Interleukin (IL)-4, IL-5 and IL-10 for neuroimmune function. Units of measure are raw concentration expressed picograms per milliliter (pg/mL). Change values are expressed and calculated as Follow-Up minus Baseline values (using raw values).
Time frame: Baseline, 5 months, 9 months
Changes in Neuroimmune Regulation Measured by Ratio of Pro-Inflammatory to Anti-Inflammatory Cytokines
Serum samples were collected to measure the pro-inflammatory:anti-inflammatory cytokine ratio (\[IL-1β + IL-6 + TNF-α\]:\[IL-13 + IL-10\]) for neuroimmune function. These values are expressed as ratios. Change values are expressed and calculated as Follow-Up minus Baseline values (using ratio values).
Time frame: baseline and 5 and 9 months post-intervention follow-up
Changes in Psychosocial Functioning
Changes in psychosocial functioning measured with the Perceived Stress Scale (PSS), Center for Epidemiologic Studies-Depression (CES-D) scale, and the subscales of the Sickness Impact Profile (SIP) for Recreation and Pastimes, and Social Interaction. Greater scores on the PSS indicate greater perceived stress (range: 0-56) and greater scores on the CES-D indicate greater depressive symptoms (range: 0-60). The SIP is divided into 'Social Interaction' and 'Recreation and Pastimes' subscales (ranges: 0-11 and 0-5, respectively), with greater scores indicating greater impact of sickness in the respective domain. Change scores are expressed and calculated as Follow-Up minus Baseline scores.
