A Biobehavioral Intervention to Reduce Adverse Outcomes in Young Adult Testicular Cancer Survivors

BEHAVIORAL

Goal-Focused Emotion-Regulation Therapy (GET)

Patients will be asked to identify value-derived goals (i.e., goals for the most important domains of one's life) and ones sufficiently important to sustain movement toward them in the short-term future. Patients will discuss their goal possibilities, providing a forum to ensure that goals are manageable and consistent with identified values. Patients will learn strategies to refine their goals (e.g., approaching goals rather than avoiding obstacles, defining markers of progress), generate pathways to goals, and address potential obstacles and blockages. The overall goal is to enhance self-regulation through improved goal navigation skills, improved sense of meaning and purpose, and better ability to regulate specific emotional responses.

BEHAVIORAL

Individual Supportive Listening

ISL sessions will be matched in terms of time and attention. Supportive therapy will be non-directive and will primarily reinforce a patient's ability to manage stressors through attentively listening and encouraging expression of thoughts and feelings, assisting the individual to gain a greater understanding of their situation and alternatives, and helping to buttress the individual's self-esteem and resilience. This will be delivered in the same manner as GET (individually) and is a common, non-directive control method in intervention research.

Change in Hospital Anxiety and Depression Scale (HADS)

Time frame: Change from Baseline (T0) to intervention completion (~8 weeks), to 3-month post-intervention (~20 weeks), and to 6-month post-intervention (~32 weeks)

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, C-reactive Protein [CRP], sTNFαRII)

Time frame: Change from Baseline (T0) to intervention completion (~8 weeks), to 3-month post-intervention (~20 weeks), and to 6-month post-intervention (~32 weeks)

The investigators will focus on four biomarkers, IL-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

Time frame: Change from Baseline (T0) to intervention completion (~8 weeks), to 3-month post-intervention (~20 weeks), and to 6-month post-intervention (~32 weeks)

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. Salivary cortisol will be analyzed with a time-resolved fluorescence immunoassay. Several indices will be computed including diurnal slope, area under the daily curve, cortisol awakening response, and total daily cortisol output.

What is a clinical trial?

A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.

Is it safe to participate?

Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.

Will I be compensated?

Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.

Will I receive a placebo instead of treatment?

When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.

Can I leave a trial if I change my mind?

Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.

How long does a clinical trial last?

Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
