A Biobehavioral Intervention for Young Men With Testicular Cancer

Change in Hospital Anxiety and Depression Scale (HADS)

The HADS was developed to assess anxiety and depression in medical patients. It purposefully excluded somatic symptoms (e.g., sleep disturbance) to reduce confounding psychological symptoms with disease or treatment. The HADS has become a "benchmark" measure of anxiety and depression among diverse clinical and nonclinical hospital populations, including individuals diagnosed with cancer. The HADS is a 14-item self-administered questionnaire, with 7 items assigned to each the HADS-Anxiety and HADS-Depression subscales. Each item is rated on a 4-point response scale (from 0 to 3). Subscale scores are typically categorized to indicate the level of anxiety or depression experienced where scores of less than 8 are categorized as normal, scores of 8-10 as borderline, and scores of 11-21 as clinical. A number of psychometric studies have established the scale's strengths, including its brevity, reliability, and validity and availability of comparison scores across different populations.

Change in Systemic Pro-inflammatory Cytokine Levels (IL-6, IL-1ra, CRP, sTNFαRII)

The investigators will focus on four biomarkers, IIL-6, IL-1ra, CRP, sTNFαRII, that indicate systemic inflammation and are associated with distress symptoms and emotion regulation. Levels will be assessed from plasma. Cytokine levels will be determined by immunosorbent assay (ELISA) according to assay manufacturer's protocols. All samples will be run in duplicate, and assays will be repeated on two separate days; intra-assay and interassay mean levels will be used in all analyses.

Change in Salivary Diurnal Cortisol Slope and Daily Output

Diurnal rhythm in salivary cortisol will be measured over three days at each assessment. Participants will collect saliva samples in their natural environment upon awakening, 30 minutes later, 8 hours later, and at bedtime. Participants will complete a diary to assess relevant health behaviors (e.g., caffeine, tobacco, alcohol consumption; physical activity, sleep) as well as daily stress. They will be instructed to avoid brushing their teeth, eating, or drinking within 20 minutes before sampling. Participants will keep samples refrigerated prior to returning them to the research laboratory and returned salivettes will be stored in a -20-degree Celsius freezer until analyzed. After data collection is complete, salivary cortisol will be analyzed with a time-resolved fluorescence immunoassay at the IISBR laboratory at UC Irvine. Several indices will be computed including diurnal slope, area under the daily curve, cortisol awakening response, and total daily cortisol output.
