Effects of physical and mental health on relationship satisfaction: a dyadic, longitudinal examination of couples facing prostate cancer

Is it time to discard the Diagnostic and Statistical Manual of Mental Disorders (DSM) in psycho-oncology?

The conceptual basis of psychopathology within cancer survivorship is critical, as the chosen conceptualisation informs assessment and explanatory models, as well as interventions and supportive care approaches. The validity of a chosen conceptualisation of psychopathology is therefore paramount for ensuring cancer survivors receive high-quality and efficacious care and support that can be iteratively improved via coordinated research efforts. In this paper, we discuss the traditional diagnostic approach to conceptualising psychopathology within cancer care, including the diagnostic system the 'Diagnostic and Statistical Manual of Mental Disorders' (DSM) [1], and the significant issues it presents within cancer survivorship. We detail and discuss how an alternate conceptualisation of psychopathology may enhance both research and practice within psycho-oncology. We ultimately pose, and provide our perspective, on the question "Is it Time to Discard the DSM in Psycho-Oncology?"

Mapping the contributions of dyadic approaches to couples' psychosocial adaptation to prostate cancer: a scoping review

INTRODUCTION

Prostate cancer is the second-most prevalent cancer diagnosis worldwide among males. Although prostate cancer affects the physical, sexual, and mental health of patients, the impact of prostate cancer on partners has also been increasingly recognized. Hence, taking a dyadic approach is of relevance. Moreover, there is evidence of the utility of dyadic approaches to the study of relational stress that chronic diseases such as prostate cancer can bring to couples, even though knowledge is sparse about prostate cancer.

OBJECTIVES

This scoping review aimed to map existing dyadic studies on the psychosocial adaptation of couples to prostate cancer.

METHODS

A systematic search of studies published from 2005 to November 2022 was conducted on electronic databases (PubMed, Cochrane Library, EBSCOHost, Scopus, and Web of Science) following PRISMA-ScR (Preferred Reporting Items for Systematic Reviews and Meta-analyses-Extension for Scoping Reviews).

RESULTS

The review included 25 eligible studies from the initial 2514 articles retrieved. Overall, the results emphasized the interdependency between couple members and suggested how partners' adaptation influences patients' adaptation to prostate cancer and vice versa, regarding several psychosocial dimensions (eg, intimacy, quality of life).

CONCLUSIONS

This work can bring awareness to health care professionals to adopt a couples approach when managing prostate cancer whenever there is a partner, due to these interdependent influences. For researchers and future studies, this work can strengthen the relevance of dyadic approaches on how couples adapt to prostate cancer and explore which other dimensions influence these complex dynamics.

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.

Mediating role of dyadic satisfaction on social support and health outcomes in a sample of military family care-givers

LAY SUMMARY

Military family caregivers (MFCs) can experience many health-related challenges associated with caregiving responsibilities. Perceived support from a spouse or partner can influence dyadic satisfaction and health outcomes among those who care for a spouse or partner. This study examined the relations among social support, dyadic satisfaction, and mental (i.e., depressive and anxiety symptoms) and physical (i.e., somatic symptoms) health outcomes in a sample of MFCs. This sample consisted of 104 MFCs who were the spouse or partner of their care recipient. The findings indicate that more support predicted greater dyadic satisfaction and greater dyadic satisfaction predicted fewer anxiety symptoms. This study highlights the importance of considering relationship-focused contributors to mental health outcomes.

Current Mental Distress Among Men With a History of Radical Prostatectomy and Related Adverse Correlates

Recent reviews and observational studies have reported that patients with prostate cancer (PCa) are at increased risk of mental health issues, which in turn negatively affects oncological outcomes. Here, we examine possible explanatory variables of mental distress in a population-based cohort of men who have undergone radical prostatectomy (RP). Data were derived from a Maritimes-Canada online survey assessing patient-reported quality of life outcomes between 2017 and 2019 administered to 136 men (47–88 years old, currently in a relationship) who have undergone RP for their PCa diagnosis. The primary outcome was a validated assessment of mental distress, the Kessler Psychological Distress Scale (K10). Urinary function was assessed using the International Prostate Symptom Score, and relationship satisfaction was assessed using the Dyadic Assessment Scale. A multivariate logistic regression assessed the contribution of urinary function, relationship satisfaction, age, multimorbidity, additional treatments, medication for depression and/or anxiety, and survivorship time. A total of 16.2% men in this sample screened positive for mental distress. The severity of urinary problems was positively associated with increased mental distress (OR = 4.79, 95% CI [1.04, 22.03]), while increased age (OR = 0.87, 95% CI [0.78, 0.97]), relationship satisfaction (OR = 0.14, 95% CI [0.3, .077]), and current medication for anxiety, depression, or both (OR = 0.09, 95% CI [0.02, 0.62]) were protective factors. Survivorship time, the presence of additional comorbidities, or PCa treatments were not identified to be statistically significant contributions to the fitted model. Here, we report that RP survivors are prone to presenting with increased mental distress long after treatment. Screening for mental distress during RP survivorship is recommended.

Dose spouses' coping skills promote qol and dyadic coping of menopausal women?

Lack of menopausal knowledge damages the quality of life (QoL) and couples' relationships. A new approach to prevent marital distress based upon stress and coping has introduced Couples Coping Enhancement Training (CCET). The present study assessed the effect of menopause care training using CCET approach on QoL and coping in menopausal women. This educational interventional study was conducted in 2019 on 80 postmenopausal women and their spouses. The couples were randomly selected from health care centers using the cluster random sampling method and were divided into control and intervention groups. Four training sessions were held for the intervention group. Data were collected using The Menopause-Specific Quality of Life (MENQOL) questionnaire, menopausal knowledge questionnaire, and Dyadic Coping Inventory (DCI) and were analyzed using independent Sample t-test, Paired Sample T-Test, and Structural Equation Modeling (SEM) in SPSS version 25 and Amos version 21 software. At the beginning of the study, there was no significant difference in menopausal knowledge, QoL, and dyadic coping between the two groups. However, the CCET approach significantly increased menopausal knowledge, coping in couples and women's QoL in the intervention group compared to the control group. CCET can help couples to cope with menopausal symptoms more efficiently.

Relationship communication and the course of psychological outcomes among couples coping with localised prostate cancer

OBJECTIVE

How couples communicate about cancer is an important predictor of psychological outcomes for men diagnosed with localised prostate cancer and their spouses. We examined the predictive role of disclosure, responsiveness, mutual avoidance, and holding back on depressive symptoms, psychological adjustment, cancer-specific distress, and cancer concerns.

METHODS

Eighty-one prostate cancer patients and their spouses completed measures of communication at baseline and measures of four psychological outcomes at baseline, five, 12, and 26 weeks after baseline. Dyadic growth models tested the effects of time and role on each outcome over time.

RESULTS

Higher disclosure and responsiveness predicted better psychological outcomes. Less mutual avoidance and holding back predicted poorer psychological outcomes. Across communication variables, individuals who engaged in poorer communication initially had poorer psychological outcomes that improved over time, whereas individuals who engaged in better communication initially maintained their more positive standing without change or changed in the positive direction. For all outcomes, those with better communication still had better psychological outcomes at six months.

CONCLUSION

Couples' cancer-specific relationship communication predicts their psychological outcomes. More research is needed to identify effective interventions, including a longer therapy course, individual communication training, or greater focus on addressing barriers to sharing and responsiveness.

The Relationship of Dyadic Coping With Emotional Functioning and Quality of the Relationship in Couples Facing Cancer-A Meta-Analysis

Objective: This study is a meta-analysis that considers the association between dyadic coping and emotional functioning, and between dyadic coping and the quality of the relationship as perceived by cancer patients and their life partners. Methods: A systematic search was conducted in the electronic databases PsycINFO, PubMed, ScienceDirect and those peer-reviewed cross-sectional and longitudinal studies published up until April 2020 that investigated these relationships were selected. Results: A total of 1,168 studies were identified, of which 10 met the inclusion criteria (N = 1,727 couples). These evidenced statistically significant positive relationships between common dyadic coping and emotional functioning and between common dyadic coping and the quality of the relationship as perceived by patients and their partners. There was also a statistically significant positive association between stress communication (by oneself), supportive dyadic coping (by oneself and by partner), and the quality of the relationship. In addition, a statistically significant negative association was found between negative dyadic coping (by oneself and by partner) and the quality of the relationship as perceived by patients' partners and also between negative dyadic coping (by oneself) and the quality of the relationship as perceived by patients. Conclusions: The results suggest the existence of a significant association between dyadic coping and emotional functioning and between dyadic coping and the quality of the relationship as perceived by members of couples facing cancer. However, these results must be interpreted with caution due to the small number of studies included in the analysis. Clinically, an understanding of the existence of such relationships is helpful for the implementation, and study of the effectiveness of, interventions aimed at improving dyadic coping in order to improve both quality of life and quality of relationship in couples where there is an oncological diagnosis.

Associations between self-rated physical Health and relationship satisfaction in couples with children

The degree to which individual self-rated physical health and concordance of self-rated physical health between partners are associated with relationship satisfaction was examined in a community sample of 399 couples with children. Couples completed self-report assessments of physical health (general health and physical functioning) and relationship satisfaction. Results suggest unique associations between partners’ general health and their own relationship satisfaction. Further, higher between-partner concordance in physical functioning was uniquely associated with higher relationship satisfaction in women. Understanding associations between health and relationship processes is crucial and has implications for future research on couple-based interventions to promote physical health.

A Systematic Review of Sexual Satisfaction in Prostate Cancer Patients

INTRODUCTION

Prostate cancer (PCa) treatment has a significant negative impact on sexual function. Because research to this date has mostly focused on the impact of PCa on erectile function, very little is known about the impact of PCa on other relevant sexual outcomes, such as sexual satisfaction.

AIM

To conduct a literature review of studies that have examined sexual satisfaction in men diagnosed with and treated for PCa.

METHODS

A systematic review was conducted using Scopus and PubMed databases to identify studies that had assessed sexual satisfaction in men with PCa. The main characteristics of each study and results regarding the impact of PCa on sexual satisfaction were extracted and examined.

MAIN OUTCOME MEASURE

The main outcome measure was studies that assessed general sexual satisfaction in men with PCa.

RESULTS

Thirty-eight articles were found regarding sexual satisfaction in PCa. Most studies did not focus on sexual satisfaction specifically, and methodologic limitations produced very mixed results. Overall, PCa treatments had a low to moderate impact on sexual satisfaction, and psychosocial interventions were more successful at improving sexual satisfaction than medical interventions. Sexual satisfaction was correlated to a large number of sexual, relational, psychological, and medical variables.

CONCLUSION

This literature review shows very mixed results about the sexual satisfaction in men with PCa. Differences in research designs, methodologic limitations, and studies conducted atheoretically limit our understanding of the mechanisms that impact sexual satisfaction in men with PCa. We propose an alternative way of conducting research on sexual satisfaction by using solid theoretical models of sexual satisfaction. Santos-Iglesias P, Rana M, Walker L.

Community pharmacy lifestyle intervention to increase physical activity and improve cardiovascular health of men with prostate cancer: a phase II feasibility study

OBJECTIVES

To assess the feasibility and acceptability of a community pharmacy lifestyle intervention to improve physical activity and cardiovascular health of men with prostate cancer. To refine the intervention.

DESIGN

Phase II feasibility study of a complex intervention.

SETTING

Nine community pharmacies in the UK.

INTERVENTION

Community pharmacy teams were trained to deliver a health assessment including fitness, strength and anthropometric measures. A computer algorithm generated a personalised lifestyle prescription for a home-based programme accompanied by supporting resources. The health assessment was repeated 12 weeks later and support phone calls were provided at weeks 1 and 6.

PARTICIPANTS

116 men who completed treatment for prostate cancer.

OUTCOME MEASURES

The feasibility and acceptability of the intervention and the delivery model were assessed by evaluating study processes (rate of participant recruitment, consent, retention and adverse events), by analysing delivery data and semi-structured interviews with participants and by focus groups with pharmacy teams. Physical activity (measured with accelerometry at baseline, 3 and 6 months) and patient reported outcomes (activation, dietary intake and quality of life) were evaluated. Change in physical activity was used to inform the sample size calculations for a future trial.

RESULTS

Out of 403 invited men, 172 (43%) responded and 116 (29%) participated. Of these, 99 (85%) completed the intervention and 88 (76%) completed the 6-month follow-up (attrition 24%). Certain components of the intervention were feasible and acceptable (eg, community pharmacy delivery), while others were more challenging (eg, fitness assessment) and will be refined for future studies. By 3 months, moderate to vigorous physical activity increased on average by 34 min (95% CI 6 to 62, p=0.018), but this was not sustained over 6 months.

CONCLUSIONS

The community pharmacy intervention was feasible and acceptable. Results are encouraging and warrant a definitive trial to assess the effectiveness of the refined intervention.

Spousal understanding and marital satisfaction in pain patients and their spouses

The current study tested the hypotheses that knee osteoarthritis (OA) patients and spouses who report more spousal understanding of patient's pain would report greater marital satisfaction. A total of 124 couples completed interviews at three time points across 18 months. Results from dyadic analyses showed that patients who felt more understood by their spouse report, and have spouses who report, higher marital satisfaction concurrently. In addition, patients who felt more understood by their spouse reported higher marital satisfaction over time. Spouses' reports of understanding also had a significant influence on the patients' and their own marital satisfaction concurrently. Results highlight the importance of spouses understanding knee OA patients' pain for both dyad members' marital satisfaction.

Prostate cancer: the influence of stigma on quality of life and relationship satisfaction for survivors and their partners

OBJECTIVES

Prostate cancer (PCa) stigma and its relationship to quality of life (QoL) is a relatively new finding. As the experiences of couples facing PCa are shared, the study examined the relationship between of PCa stigma, QoL, and relationship satisfaction of PCa survivors and their spouses.

DESIGN

A correlational design with dyadic data was used.

SAMPLE

Participants (N = 80 dyads) were PCa survivors and their spouses sampled from an oncology center and PCa support groups.

METHODS

Structural equation modeling was used to assess how stigma related to the QoL and relationship satisfaction of participants.

FINDINGS

Stigma had a negative association with QoL, but not relationship satisfaction. There were no significant demographic differences in regards to stigma.

CONCLUSION

Overall, stigma has a relationship with the experience of couples, but not with every aspect of their experience. Implications for psychosocial providers: Implications for clinicians in regards to addressing PCa stigma with clients and areas for future research are discussed.

Health-related quality of life in patients with prostate cancer and their spouses: Results from a longitudinal study

PURPOSE

The purpose of this study was to explore changes in HRQoL (health-related quality of life) and identify the associated factors in patients with prostate cancer and their spouses during the year following their diagnosis of prostate cancer.

METHODS

The longitudinal study design consisted of 179 patients and 166 spouses, using discretionary sampling, at five Finnish central hospitals. Participants completed a self-reported RAND-36-Item Health Survey at three time-points: time of diagnosis and 6 and 12 months later. Changes in HRQoL were analysed using descriptive statistics and non-parametric tests. Linear mixed-effects models were used to identify the factors associated with the changes in HRQoL in the patients and their spouses.

RESULTS

On average, the HRQoL of patients with prostate cancer changed in physical functioning (p = 0.015), emotional well-being (p = 0.029) and general health (p = 0.038) were statistically significant over the 12-month study period. In spouses, statistically significant changes in HRQoL were not observed. Interaction between the age of participants and changes in HRQoL were statistically significant.

CONCLUSIONS

Findings in this study suggest that interventions aimed at improving the HRQoL of patients should support a few different dimensions of HRQoL for the patients themselves than for their spouses. Nurses should pay more attention to elderly couples.

Comparing Two Models of Dyadic Change: Correlated Growth Versus Common Fate

The analysis of longitudinal dyadic data often requires complex structural models. Two models of dyadic change, the correlated growth model and the common fate growth model, differ in their description of change. The correlated growth model estimates separate but correlated growth trajectories for each member of a dyad. The common fate growth model treats the dyad as the unit of analysis and estimates growth parameters for the dyad. Relationship and life satisfaction are important outcomes that feature prominently in the relationship literature and must be modeled adequately to be understood. In a sample of 325 romantic couples, the relative efficacy of these two models for describing change in relationship and life satisfaction is compared. The common fate growth model better described relationship satisfaction, while the correlated growth model provided superior fit to life satisfaction. Implications for the modeling of dyadic data are discussed.

Predictors of Patient and Partner Satisfaction Following Radical Prostatectomy

INTRODUCTION

The diagnosis and treatment of prostate cancer adversely affects the physical and emotional well-being of patients and partners and has been associated with sexual dysfunction in patients and their intimate partners.

AIM

To identify predictors of sexual satisfaction in prostate cancer survivors and their partners based on a review of the current literature.

METHODS

We performed a comprehensive review of the PubMed database from January 2000 to May 2017 focused on the (i) prevalence of patient and partner sexual dysfunction related to radical prostatectomy, (ii) differences in patient and partner perspectives of sexual function and dysfunction, and (iii) predictors of patient and partner sexual satisfaction after radical prostatectomy.

MAIN OUTCOME MEASURES

Patient- and partner-reported sexual satisfaction.

RESULTS

There is a paucity of published data examining sexual satisfaction in prostate cancer survivors and their partners. Patients and partners can have different expectations of sexual outcomes after radical prostatectomy and different attitudes toward the relative importance of recovery of sexual function after surgery. Available data suggest that patients' and partners' mental and physical health and the quality of communication between them are important contributors to their sexual satisfaction. Patient-perceived partner support also is associated with better patient-reported erectile function and greater relationship satisfaction.

CONCLUSION

Mental health, physical health, quality of interpersonal communication, and patient-perceived partner support appear to be the most important predictors of sexual satisfaction for patients and partners in the post-prostatectomy period. There is a definite need for further research on this topic to develop interventions to improve sexual function and quality of life for prostate cancer survivors and their intimate partners.

The effects of beliefs about AIDS-related death on quality of life in Chinese married couples with both husband and wife infected with HIV: examining congruence using the actor-partner interdependence model

Background

This cross-sectional study examined the actor and partner effects of beliefs about AIDS-related death on quality of life in Chinese married couples in which both were living with HIV.

Methods

A total of 49 married couples in central China who were both infected with HIV completed measures to assess their beliefs about AIDS-related death and quality of life.

Results

In the actor-partner interdependence model, the husband-wife dyad showed congruence in their beliefs about AIDS-related death (r = .40) and quality of life–mental health summary (r = .31), respectively, within the couple. Both actor and partner effects of beliefs about AIDS-related death on the quality of life–mental health summary, rather than the quality of life–physical health summary, were significant within the husband-wife dyad.

Conclusions

Our findings indicate the dyadic interdependence of beliefs about AIDS-related death and the quality of life–mental health summary in married couples. Psychosocial interventions that target a reduction of negative death beliefs and enhancement of well-being in the context of HIV should treat the couple as a unit.

Posttraumatic growth in breast cancer survivors and their husbands based on the actor-partner interdependence model

OBJECTIVE

This study aimed to verify actor and partner effects, by examining the effects of self-esteem, relationship quality, and subjective distress on posttraumatic growth in breast cancer survivors and their spouses, and involved a structural analysis of descriptive cause-and-effect relationships to verify the suitability of the actor-partner interdependence model.

METHODS

A structured questionnaire was used to collect data from breast cancer survivors and their spouses at outpatient centers, wards, and patient meetings in 4 general hospitals in Seoul between April 13 and September 20, 2015. Data for 336 individuals (168 couples) were analyzed. The suitability of the hypothetical model was assessed via SPSS Win 21.0 and AMOS 21.0. Actor and partner effects on posttraumatic growth in breast cancer survivors and their spouses were examined.

RESULTS

Self-esteem, relationship quality, and subjective distress exerted significant actor effects, and subjective distress exerted a significant partner effect on posttraumatic growth in breast cancer survivors. Relationship quality and support exerted significant actor effects, and self-esteem, relationship quality, and subjective distress exerted significant partner effects on posttraumatic growth in spouses.

CONCLUSIONS

Posttraumatic growth in breast cancer survivors was influenced by not only relationship quality and spouses' self- esteem but also subjective distress; therefore, solidarity between breast cancer survivors and their spouses was important and should be maintained to provide healthy relationship support and enhance posttraumatic growth. Further, health care providers should include spouses in health-related education and involve them in interventions and family support programs for couples.

Life after prostate cancer diagnosis: protocol for a UK-wide patient-reported outcomes study

BACKGROUND

Prostate cancer and its treatment may impact physically, psychologically and socially; affecting the health-related quality of life of men and their partners/spouses. The Life After Prostate Cancer Diagnosis (LAPCD) study is a UK-wide patient-reported outcomes study which will generate information to improve the health and well-being of men with prostate cancer.

METHODS AND ANALYSIS

Postal surveys will be sent to prostate cancer survivors (18-42 months postdiagnosis) in all 4 UK countries (n=∼70 000). Eligible men will be identified and/or verified through cancer registration systems. Men will be surveyed twice, 12 months apart, to explore changes in outcomes over time. Second, separate cohorts will be surveyed once and the design will include evaluation of the acceptability of online survey tools. A comprehensive patient-reported outcome measure has been developed using generic and specific instruments with proven psychometric properties and relevance in national and international studies. The outcome data will be linked with administrative health data (eg, treatment information from hospital data). To ensure detailed understanding of issues of importance, qualitative interviews will be undertaken with a sample of men who complete the survey across the UK (n=∼150) along with a small number of partners/spouses (n=∼30).

ETHICS AND DISSEMINATION

The study has received the following approvals: Newcastle and North Tyneside 1 Research Ethics Committee (15/NE/0036), Health Research Authority Confidentiality Advisory Group (15/CAG/0110), NHS Scotland Public Benefit and Privacy Panel (0516-0364), Office of Research Ethics Northern Ireland (16/NI/0073) and NHS R&D approval from Wales, Scotland and Northern Ireland. Using traditional and innovative methods, the results will be made available to men and their partners/spouses, the funders, the NHS, social care, voluntary sector organisations and other researchers.
