NCT03177707

Brief Summary

With improvements in detection and treatment of prostate cancer (PCa), more men than ever are living with side effects from PCa treatment; most distressingly, treatment side effects include problems with sexual functioning (e.g. erectile dysfunction, climacturia, inorgasmia). This study aims to develop a mindfulness-based group treatment for couples with sexual functioning complaints post-PCa treatment. Couples will be invited to a four-session mindfulness-based treatment group. Pre- and post-treatment outcomes (e.g., distress, sexual functioning/enjoyment, relationship satisfaction, treatment adherence) will assess feasibility and effectiveness of this novel treatment for couple's sexual lives after PCa.

Outcome Measures

Primary Outcomes (8)

  • Sexual correlates: Self-reported sexual functioning

    Depending on sexual orientation and gender, individuals will complete either (1) International Index of Erectile Functioning (heterosexual men), International Index of Erectile Functioning for Men who have sex with men (gay men), or Female Sexual Functioning Index (female partners)

    Change from baseline to post-intervention (5 weeks)

  • Sexual correlates: Self-reported erectile functioning

    Depending on sexual orientation and gender, individuals will complete either (1) International Index of Erectile Functioning (heterosexual men), International Index of Erectile Functioning for Men who have sex with men (gay men), or Female Sexual Functioning Index (female partners)

    Change from post-intervention (5 weeks) to 6-month follow up

  • Sexual correlates: GMSEX

    GMSEX (Lawrance \& Byers, 1992). The GMSEX is a 5-item measure of distress related to sexual functioning with one's partner.

    Change from baseline to post-intervention (5 weeks)

  • Sexual correlates: GMSEX

    GMSEX (Lawrance \& Byers, 1992). The GMSEX is a 5-item measure of distress related to sexual functioning with one's partner.

    Change from post-intervention (5 weeks) to 6-month follow up

  • Sexual correlates: Sexual activity scale

    This is a questionnaire developed by the study lead that asks individual to rate the frequency of times that they engaged in a range of sexual activities over 3 time-periods: (a) ever, (b) since their/their partner's prostate cancer surgery, and (c) in the past 4 weeks.

    Change from post-intervention (5 weeks) to 6-month follow up

  • Sexual correlates: Adapted dyadic adjustment scale

    Adapted dyadic adjustment scale (A-DAS; Sharpley \& Cross, 1982). The A-DAS is a validated, 7-item measure that assesses relationship adjustment.

    Change from baseline to post-intervention (5 weeks)

  • Sexual correlates: Adapted dyadic adjustment scale

    Adapted dyadic adjustment scale (A-DAS; Sharpley \& Cross, 1982). The A-DAS is a validated, 7-item measure that assesses relationship adjustment.

Study Arms (2)

Immediate start

EXPERIMENTAL

Patients begin the Mindfulness-based Therapy Group for Couples treatment group immediately after enrollment

Other: Mindfulness-based Therapy Group for Couples

Delayed start

OTHER

Patients begin the Mindfulness-based Therapy Group for Couples after a delay post-study enrollment (approximately 6 months)

Other: Mindfulness-based Therapy Group for Couples

Interventions

Eligible couples will take part in a 4-session mindfulness-based therapy group for couples. The groups will last 2 hours in length, for a total of 8 hours of treatment time, and sessions will be scheduled once per week in successive weeks. The groups will have one highly experienced female facilitator, who is the Study Coordinator. The facilitator led the design of the treatment manual, and has experience in facilitating similar groups. The facilitator will follow a detailed, empirically-informed mindfulness-based treatment manual that was designed for the purpose of this study. All groups will take place in a private group treatment room at Vancouver General Hospital.
