A randomized comparison of group mindfulness and group cognitive behavioral therapy vs control for couples after prostate cancer with sexual dysfunction.

BACKGROUND: Sexual dysfunction is the most common and most distressing consequence of prostate cancer (PCa) treatment and has been shown to directly affect the sexual function and quality of life of survivors' partners. There are currently no established therapies to treat the emotional and psychological burden that sexual issues impose on the couple after PCa. AIM: Our study examined the impact of 2 therapies-cognitive behavioral therapy (CBT) and mindfulness therapy-on sexual, relational, and psychological outcomes of PCa survivor and partner couples. METHODS: PCa survivors (n = 68) who self-reported current sexual problems after PCa treatments and their partners were randomized to 4 consecutive weeks of couples' mindfulness therapy, couples' CBT, or no treatment (control). OUTCOMES: Couples' sexual distress, survivors' sexual satisfaction, and couples' relationship satisfaction, quality of life, psychological symptoms (anxiety and depression), and trait mindfulness were measured at baseline, 6 weeks after treatment, and 6 months after treatment. RESULTS: Sexual distress and sexual satisfaction were significantly improved 6 weeks after the CBT and mindfulness interventions as compared with the control group, but only sexual distress remained significantly improved at 6 months. Relationship satisfaction decreased and more so for partners than survivors. There were increases in domains of quality of life for survivors vs their partners 6 months after treatments and an overall increase in general quality of life for couples 6 weeks after mindfulness. There were no significant changes in psychological symptoms and trait mindfulness. Qualitative analysis showed that the mindfulness intervention led to greater personal impact on couple intimacy after the study had ended. CLINICAL IMPLICATIONS: CBT and mindfulness can be effective treatments for helping couples adapt to and cope with changes to their sexual function after PCa treatments and could help improve the most common concern for PCa survivors-that is, couples' sexual intimacy-after cancer, if added to routine clinical care. STRENGTHS AND LIMITATIONS: We used established standardized treatment manuals and highly sensitive statistical methodology and accounted for covariable factors and moderators of primary outcomes. Due to difficulty in recruitment, we had a smaller control group than treatment, reducing our power to detect between-group differences. Our sample was mostly White, heterosexual, and affluent, thereby limiting the generalizability. CONCLUSION: This is the first randomized clinical trial to test and demonstrate benefits among PCa survivors and partners' sexual outcomes after CBT and mindfulness as compared with a nontreatment control group.

Preliminary Development of a Mindfulness-Based Group Therapy to Expand Couples' Sexual Intimacy after Prostate Cancer: A Mixed Methods Approach.

INTRODUCTION: Sexual health and intimacy are consistently reported among the top unmet supportive care needs of prostate cancer (PC) survivors. With an aging population and advances in PC detection and treatment, the need for better PC sexual health interventions is acute. AIM: Examine the feasibility of a mindfulness-based therapy group aimed at improving sexual intimacy for couples following PC treatments. METHODS: A 4-session mindfulness-based group intervention was developed for PC survivors (mean age 65.6 yrs) and their partners (mean age 61.4 yrs). A mixed-methods approach was adopted to account for small sample sizes (N = 14 couples). Findings will guide future treatment refinement via participants' lived experiences. MAIN OUTCOME MEASURES: Quantitative outcomes assessed pretreatment, immediately after treatment, and 6 months later included relationship adjustment, sexual satisfaction, sexual function, depression, anxiety, and mindfulness. Qualitative outcomes used Grounded Theory Approach following posttreatment exit interviews. RESULTS: Effect sizes 6 months posttreatment indicated moderate improvements in overall sexual satisfaction and large increases in mindfulness in PC survivors, small decreases in sexual intimacy reported by partners, and small increases in anxiety in PC survivors and partners. Qualitative outcomes revealed 6 themes: (i) PC treatments must view PC as a couple's disease; (ii) PC treatments must consider the impact of illness on individuals and the couple; (iii) Mindfulness was a valued treatment modality; (iv) Individual factors contribute to outcomes, and therefore, must be considered; (v) Multiple perceived mechanisms for change exist; (vi) Group format is a therapeutic element of the process. CONCLUSION: An acceptance-based approach to sexual intimacy needs among PC survivors and their partners is feasible. While this small-scale preliminary study suggests that mindfulness may address some currently unmet needs among this population, randomized clinical trials are needed.

Sexual Health Recovery For Prostate Cancer Survivors: The Proposed Role Of Acceptance And Mindfulness-Based Interventions.

INTRODUCTION: 1 in every 7 Canadian men is affected by prostate cancer. Given impressive advances in detection, treatment, and survival rates, there is a considerable focus on survivors' supportive care needs. Among the top unmet supportive care needs for prostate cancer survivors are concerns related to sexual health and intimacy. AIM: To provide a rationale for introducing mindfulness- and acceptance-based approaches into the role of psychosexual interventions aimed at improving sexual satisfaction among prostate cancer survivors (and their partners). METHODS: A literature review was performed to examine the prevalence of sexual difficulties after prostate cancer treatment and the efficacy of current pharmacologic and psychological treatment approaches. MAIN OUTCOME MEASURE: The main outcome measure was focused on sexual satisfaction in prostate cancer survivors. RESULTS: Current pharmacologic interventions for sexual difficulties after prostate cancer treatment are not fully meeting the needs of prostate cancer survivors and their partners. Conclusions cannot be drawn from existing psychological interventions because of methodologic inconsistencies. Additionally, the focus on erectile function as a measure of treatment effectiveness is likely to instill a greater sense of hopelessness and loss for prostate cancer survivors, which may exacerbate issues around sexual intimacy and satisfaction. An impressive body of evidence supports the role of mindfulness in improving women's sexual functioning and there is preliminary evidence suggesting the efficacy of this approach for improving men's sexual functioning. CONCLUSION: We propose that psychosexual interventions that prioritize mindfulness and acceptance-based frameworks may help men to tune into sensations while challenging the foci on performance and erections, thereby increasing the potential for improvement to sexual satisfaction among prostate cancer survivors.

Menstrual cycle phase predicts women's hormonal responses to sexual stimuli.

A robust body of research has demonstrated shifts in women's sexual desire and arousal across the menstrual cycle, with heightened desire and arousal coincident with heightened probability of conception (POC), and it is likely that ovarian hormones modulate these shifts. However, studies in which women are exposed to audiovisual sexual stimuli (AVSS) at high POC (mid-follicular) and low POC (luteal) phases have failed to detect significant differences in genital or subjective arousal patterns based on menstrual cycle phase. Here, we tested whether hormonal responsivity to AVSS differs as a function of cycle phase at testing, and whether phase during which participants were first exposed to AVSS influences hormonal responsivity in subsequent test sessions. Twenty-two naturally cycling heterosexual women were exposed to AVSS during the follicular and luteal phases, with phase at first test session counterbalanced across participants. Salivary samples were collected before and after AVSS exposure. Estradiol increased significantly during both follicular and luteal phase sessions, and increases were higher during the follicular phase. Testosterone (T) increased significantly only during the follicular phase session, while progesterone (P) did not change significantly during either cycle phase. Session order and current cycle phase interacted to predict P and T responses, such that P and T increased during the follicular phase in women who were first tested during the luteal phase. These data suggest that menstrual cycle phase influences hormonal responsivity to AVSS, and contribute to a growing body of clinical and empirical literature on the neuroendocrine modulators of women's sexuality.
