Outcome Measures

Primary Outcomes (3)

  • Feasibility of Intervention through Study Accrual

    Feasibility will be measured through study accrual, retention/attrition, and session completion rates, based on similar couple-based behavioral interventions in advanced cancer. Accrual feasibility will be indicated by: Recruitment and accrual efficiency, defined as enrolling \>50% of eligible approached couples (i.e., 45 couples after approaching fewer than 90 couples).

    From enrollment through post-intervention assessment at approximately 8 weeks

  • Feasibility of Intervention through Intervention Retention Rates

    Feasibility will be measured through study accrual, retention/attrition, and session completion rates, based on similar couple-based behavioral interventions in advanced cancer. Retention feasibility will be indicated by: Intervention retention rate of \> 70% Mindful PaCT couples (i.e., complete assessments at both pre-and post-intervention timepoints).

    From enrollment through post-intervention assessment at approximately 8 weeks

  • Feasibility of Intervention through Intervention Completion Rates

    Feasibility will be measured through study accrual, retention/attrition, and session completion rates, based on similar couple-based behavioral interventions in advanced cancer. Session completion feasibility will be indicated by: Intervention completion rate, defined by attendance of all 4 Mindful PaCT sessions, in \> 50% of couples.

    From enrollment through post-intervention assessment at approximately 8 weeks

Secondary Outcomes (1)

  • Participant Satisfaction Score of the PaCT Program

    At post-intervention assessment at approximately 8 weeks

Study Arms (2)

Mindful PaCT

EXPERIMENTAL

Patient-partner dyads assigned to this arm receive Mindful PaCT, a couple-based mindfulness program delivered through four weekly, 60- to 75-minute sessions via secure videoconferencing. Sessions are facilitated by a trained interventionist. Couples also receive a program workbook and access to supplemental audio and video mindfulness practices for use between sessions.

Behavioral: Couple-based Mindfulness Intervention

Wellness PACT

PLACEBO COMPARATOR

Patient-partner dyads assigned to this arm receive Wellness PaCT, a couple-based educational program delivered through four weekly, 60- to 75-minute sessions via secure videoconferencing. Sessions are facilitated by a trained interventionist and address general wellness, sleep and fatigue, diet and nutrition, and exercise and physical activity. Couples also receive a program workbook and supplemental educational resources for use between sessions.

Behavioral: Health and Wellness Education Control Condition

Interventions

Mindful PaCT is a manualized, couple-based mindfulness intervention designed to reduce distress and strengthen coping among patients with metastatic colorectal cancer and their partners. The intervention includes four weekly, 60- to 75-minute sessions delivered to each patient-partner dyad via secure videoconferencing by a trained interventionist. Sessions address four core mindfulness competencies: awareness, acceptance, compassion, and connection. Intervention content includes mindfulness-based education, guided experiential exercises, and skill-building activities designed to support individual and relational coping and adjustment in the context of advanced cancer. Couples receive a workbook containing session materials and access to supplemental audio and video recordings of guided mindfulness practices to support between-session practice and continued skill development.

Mindful PaCT

Wellness PaCT is a manualized, couple-based educational intervention designed as an active, attention-matched control condition for patients with metastatic colorectal cancer and their partners. The intervention includes four weekly, 60- to 75-minute sessions delivered to each patient-partner dyad via secure videoconferencing by a trained interventionist. Each session focuses on a wellness topic relevant to coping with metastatic colorectal cancer: general wellness, sleep and fatigue, diet and nutrition, and exercise and physical activity. Intervention content includes health education and structured activities intended to support healthy lifestyle behaviors in the context of advanced cancer. Couples receive a workbook containing session materials and access to supplemental educational resources to support continued learning between sessions.

Eligibility Criteria

Age18 Years - 85 Years
Sexall
Healthy VolunteersYes
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Provision to sign and date the consent form.
  • Stated willingness to comply with all study procedures and be available for the duration of the study.
  • Be aged \> 18 years to 85.
  • Fluent in English language. All study materials, including the informed consent form, participant workbooks, and questionnaires, are currently available only in English. Participation requires the ability to independently read and engage with written study materials (including the participant workbook), which are integral to the intervention session content and home practices. Therefore, individuals who are unable to read study materials in English are not eligible to participate. At this time, the intervention has not been translated or validated in other languages, therefore participation is limited to individuals who can read, speak, and understand English to ensure that participants are able to fully engage with study activities.
  • Be a person (i.e., patient) diagnosed with metastatic colorectal cancer (mCRC) or a partner (e.g., spouse) of someone diagnosed with mCRC.
  • Indicates a score \>0 on the Distress Thermometer
  • Has access to computer/internet through with video-conferencing (phone, laptop, tablet, desktop computer)
  • Additional eligibility criteria include:
  • Has a current diagnosis of metastatic (Stage IV, recurrent) colorectal cancer
  • Has an ECOG status \<2 or otherwise deemed appropriate for study participation by a clinician
  • Is in a committed relationship with a romantic partner for \>6 months. Monogamy is not required for eligibility; however, in cases of polyamorous relationships, the patient will designate a primary partner for participation in the study.
  • Has been in a committed relationship \>6 months with a patient who meets the above eligibility criteria
  • Eligibility for relationship status will be self-reported by participants during recruitment.

You may not qualify if:

  • One or both members of the couple has an active or poorly controlled serious mental illness (e.g., psychotic disorder), cognitive impairment (e.g., dementia), or medical condition (e.g., significant impaired sight/hearing) that would compromise participation.
  • The couple is currently in active couples (e.g., marital) therapy together.
