Patient and spouse illness beliefs and quality of life in prostate cancer patients

Interventions strategies and their efficacy in illness perceptions in patients with cancer: A systematic review and meta-analysis

PURPOSES

To identify intervention strategies for improving illness perception (IP) of cancer patients and/or family caregivers; and to examine the effects of IP interventions by meta-analysis.

METHODS

A systematic search was performed to identify literature that focused on improving the IP of cancer patients and/or family caregivers from the establishment of eight databases to August 2023. Manual screening was also applied. The IP intervention strategies for cancer populations were synthesized basing the CSM. Meta-analysis was conducted to assess the effects of IP interventions on health outcomes. Multiple subgroup analyses of the same intervention conditions were conducted to explore the optimal IP-focused intervention.

RESULTS

18 studies were included. 11 studies were conducted in a meta-analysis. No studies on family caregivers' IP were identified. Compared to general care, subgroup analysis revealed that IP interventions had favorable effects on cancer patients' IP as well as quality of life and other outcomes. Six IP intervention strategies (information support, cognitive reframing, emotion adjustment, active coping, effective appraisal, and self-social identification) were generated. Meta-analysis showed that compared with theory-less studies (Z = 8.64, p < 0.01) and single delivery formats (Z = 3.66, p < 0.01), the theory-based interventions (Z = 10.86, p < 0.01) and mixed delivery formats (Z = 7.15, p < 0.01) had higher positive effects on IP outcomes.

CONCLUSIONS

The positive outcomes of IP intervention focusing on cancer patients were highlighted. IP traits and patients' and their caregivers' needs in coping with specific cancer types should be explored before the intervention design. More IP interventions targeting cancer dyads are warranted to develop in the future.

The dyadic regulation approach of coping and illness representations in female cancer patients and their partners

Purpose

Adjustment to any illness is a 'dyadic' process whereby patients and their partners mutually determine each other's perceptions, behaviours, and well-being. The present study explored the association between dyadic coping strategies and illness representations in newly diagnosed female cancer patients and their partners.

Methods

The sample consisted of 92 female cancer patient-partner pairs from 3 oncology hospitals in Greece and Cyprus. The Actor Partner Interdependence Model was applied to test for dyadic regulation effects.

Results

The findings revealed that patients' evaluations of dyadic coping were related to their own illness representations and, in some cases, to partners' illness representations of control. However, partner evaluations of dyadic coping were not associated with either patients' or their own illness representations. Relationship satisfaction did not moderate the relationship between dyadic coping and illness representations.

Implications

The study suggests that patients' perceptions of support provided by themselves and their partners play a significant role in shaping their illness representations. Future research could delve into the underlying reasons for the observed differences in the impact of dyadic coping on illness representations between patients and partners, considering factors such as gender roles and specific gender-related issues.

Development and initial psychometric evaluation of the Perceptions of Parental Illness Questionnaire for Cancer

OBJECTIVE

To evaluate the psychometric properties of the Perceptions of Parental Illness Questionnaire for Cancer (PPIQ-C) among adolescents and young adults (AYAs).

METHODS

A sample of 372 AYAs (aged 12-24 years) who had a parent diagnosed with cancer completed the PPIQ-C and the Kessler Psychological Distress Scale (K10). Exploratory factor analyses were conducted to examine the dimensional structure of the PPIQ-C. Scale reliability was evaluated using Cronbach's alpha (α) and McDonald's omega (ω). Pearson correlation analyses were conducted to assess construct validity by examining correlations between PPIQ-C subscale scores and K10 total scores.

RESULTS

The PPIQ-C is organised into three sections, each with a separate factor structure for items representing identity, core (emotional representations, coherence, timeline, consequences, and controllability), and cause dimensions of the Common-Sense Model of Self-Regulation. Exploratory factor analyses determined the structure of each section: identity items comprised two subscales (12 items), core items comprised 10 subscales (38 items), and cause items comprised three subscales (11 items). Scale reliability was acceptable for all subscales, except the cause subscale chance or luck attributions (α = 0.665). Correlations between PPIQ-C subscale scores and K10 total scores provided support for construct validity.

CONCLUSIONS

Preliminary evidence suggests that the PPIQ-C is a reliable, valid, and useful tool for assessing illness perceptions among AYAs with a parent with cancer. The PPIQ-C may be a useful addition to both clinical practice and future research, however further evaluation work is needed to confirm its structure and robustness prior to use.

Illness perceptions and outcome in multiple sclerosis: A systematic review of the literature

According to Leventhal's self-regulation model, ill people construct personal representations of their disease, namely illness perceptions, which impact their coping strategies and the emotional response to their condition. Since these representations develop in the social environment, the individuals' perceptions may also be related to the opinions of their caregivers. This systematic review aims at synthesising and critically appraising literature pertaining the relationship between illness perceptions and outcome in persons with multiple sclerosis and their caregivers. A literature search was conducted in MEDLINE, PsycINFO, and CINAHL. Only papers with the following characteristics were included: quantitative studies; written in English or Italian; published from 1992; investigating the relationship between illness perceptions and any outcome in persons with multiple sclerosis and/or their caregivers; using validated scales assessing illness perceptions. Twenty papers were included and appraised through the 16-item Quality Assessment Tool for Studies with Diverse Designs. The quality of the papers was acceptable. Eighteen out of 20 papers reported the existence of a moderate effect size when analysing the relationship between illness perceptions and outcome, whereby "positive" perceptions (e.g. stronger beliefs of control) related to better outcomes, while "negative" ones (e.g. attribution of negative consequences to the disease) related to worse outcome.

Comparative systematic review of the psychometric properties of measures of illness perceptions in family members of individuals diagnosed with a chronic physical illness

Although illness perceptions have significant implications for psychological morbidity in those diagnosed with a physical illness, the strength of this relationship in their family members remains understudied. The validity of findings is dependent on the quality of the instruments used; therefore, it is essential that psychometrically robust measures of illness perceptions are available. The purpose of this systematic review was to identify, assess and compare the psychometric properties of instruments designed to measure illness perceptions in family members of individuals with chronic physical illnesses. A systematic search was conducted using MEDLINE, PubMed, CINAHL, Scopus and PsycINFO databases, and supplemented with forward and backward searches. Studies were included in the review if they described the development, adaptation or psychometric evaluation of an instrument designed to measure illness perceptions in family members of an individual with a chronic physical illness. The methodological quality of included studies was assessed using the COSMIN Risk of Bias checklist. The psychometric quality of instruments was evaluated using published quality assessment criteria. Eleven articles describing nine different instruments were included in the review. Almost all instruments were designed for parents of a child with a chronic illness. There was wide variation in the quality of methods used to develop, adapt or evaluate the instruments, and missing information restricted the evaluation of psychometric properties. Further validation is needed for all instruments before meaningful conclusions can be drawn. Findings indicate that measurement of illness perceptions in children or siblings of an individual with a chronic physical illness has been largely ignored. Future research addressing this gap would be an important addition to the current body of work examining illness perceptions in family members.

The dissimilarity between myocardial infarction patients' and spouses' illness perception and its relation to patients' lifestyle

AIM AND OBJECTIVES

To examine the dissimilarity between Chinese myocardial infarction (MI) patients' and spouses' illness perceptions (IPs), and to explore the relationship between patients' IP, differences in couples' IP and patients' lifestyle after discharge.

BACKGROUND

An individual's IP is affected and moderated by several factors, including the social context. One of the most influential members of the social network of patients is the spouse.

DESIGN

Cross-sectional design.

METHODS

From April 2016-April 2017, 111 MI patients and their spouses were recruited. Before discharge from hospital, revised Illness Perception Questionnaire was administered to MI patients and their spouses separately. Two months after discharge, patients' lifestyle was assessed using Health Promoting Lifestyle Profile II. The manuscript was organised according to STROBE guidelines.

RESULTS

Spouses were more likely to believe that the illness would last for a long time, and patients perceived MI as being more controllable than their spouses did. The patient-spouse dissimilarity in the perception of consequences was negatively correlated with both nutrition and stress control behaviours. Patients in couples with more dissimilar perception of environmental factors as a cause were more likely to choose a healthy diet, while patients in couples with more dissimilar perceived treatment control were more able to control stress.

CONCLUSION

There are both similarities and dissimilarities between MI patients' and spouses' IP, and these dissimilarities contributed the majority of the explained variance in patients' lifestyle after discharge.

RELEVANCE TO CLINICAL PRACTICE

We should consider both couples when examining how a patient copes with a chronic illness.

Socially transmitted placebo effects

Medical treatments typically occur in the context of a social interaction between healthcare providers and patients. Although decades of research have demonstrated that patients' expectations can dramatically affect treatment outcomes, less is known about the influence of providers' expectations. Here we systematically manipulated providers' expectations in a simulated clinical interaction involving administration of thermal pain and found that patients' subjective experiences of pain were directly modulated by providers' expectations of treatment success, as reflected in the patients' subjective ratings, skin conductance responses and facial expression behaviours. The belief manipulation also affected patients' perceptions of providers' empathy during the pain procedure and manifested as subtle changes in providers' facial expression behaviours during the clinical interaction. Importantly, these findings were replicated in two more independent samples. Together, our results provide evidence of a socially transmitted placebo effect, highlighting how healthcare providers' behaviour and cognitive mindsets can affect clinical interactions.

Positive and negative affect and well-being in cardiac patients and their spouses: the mediating role of illness representations

OBJECTIVE

The aim of this study was to examine whether illness representations of control and consequences mediate the relation of cardiac patients' affect to well-being. A further aim was to examine this indirect relationship at a dyadic level (i.e. patient and spouse).

DESIGN AND MAIN OUTCOME MEASURES

One hundred and four patients with a cardiovascular disease and their spouses participated in the study. Positive and negative affect was assessed at baseline; illness representations were assessed 2 months later, and physical and psychological well-being 4 months later.

RESULTS

Illness representations generally mediated the impact of patients' and spouses' affect on well-being, while several actor and partner effects were found. However, it was only positive affect that was indirectly related to well-being, while the representations of personal and treatment control chiefly acted as mediators. The effects were stronger for patients than spouses, as well as for physical well-being.

CONCLUSION

The results underline the strong connection between illness-related self-regulation and the overall person/environment interaction as depicted by affect. They also indicate the need to integrate theories on adaptation to illness, with models describing adaptation of couples to stressful conditions, and specific theories about the role of emotion in adaptation to illness.

The relation of spouse illness representations to patient representations and coping behavior: A study in couples dealing with a newly diagnosed cancer

The central role of spouses/partners in patients' adaptation to cancer is well-established, but few studies have examined how partners facilitate adaptation. The Common Sense Model posits that a representation of illness as more controllable and less threatening promotes adaptive coping, but this has not been examined in a dyadic context. This cross-sectional study examined the relations of spouse illness representations of personal and treatment control, and emotional representations to recently diagnosed cancer patients' coping behaviors, through patient illness representations. One hundred forty-nine heterosexual couples (39.60% female patients; 77.18% dealing with early stage cancer) participated in the study. Structural Equation Modeling showed that spouse illness representations were related to patient coping directly and indirectly through patient illness representations. Both partners' representations of control were related to greater patient adaptive coping, and both partners' emotional representations were related to greater dysfunctional coping. These findings highlight the importance of partner illness representations in patients' adaptation to cancer. They also suggest that early intervention programs that address both partners' illness representations may enhance patients' adaptation to cancer.

Managing Type 2 diabetes as a couple: The influence of partners' beliefs on diabetes distress over time

AIMS

Partners and spouses have an important role in supporting healthy self-care in adults with Type 2 diabetes. While evidence has shown that the beliefs held by people with diabetes influence emotional wellbeing, little is known about the long-term impact of partners' illness beliefs on diabetes distress.

METHODS

Persons with Type 2 diabetes (pwt2d) and their partners completed a questionnaire at baseline (N = 75 couples) and 12 months later (N = 45 couples). Measures included demographic/clinical parameters, the Revised Illness Perception questionnaire, and the Diabetes Distress Scale. A repeated measures ANOVA was used to examine change in measures over time. Multiple regression and moderation analysis were used to explore the indirect influence of partners beliefs on diabetes distress at baseline and follow-up.

RESULTS

Illness perceptions and diabetes distress in pwt2d and partners did not change overtime. Partners' beliefs about the controllability, chronicity, and predictability of symptoms of diabetes moderated the relationship between the corresponding pwt2d beliefs and diabetes distress. These indirect effects were observed across both time points.

CONCLUSIONS

Conflicting illness perceptions about the controllability and chronicity of diabetes, and congruous negative perceptions about diabetes symptoms among couples sustain distress overtime. Targeting the beliefs of couples to improve communication and understanding may reduce diabetes distress.

Perceived social support and the sense of coherence in patient-caregiver dyad versus acceptance of illness in cancer patients

BACKGROUND

Acceptance of illness is a significant determinant of further coping with a disease. Development of illness acceptance may be associated with the sense of coherence and perception of social support. Cancer is an example of a crisis situation, which affects both the patient and his/her close relatives. Consequently, acceptance of illness may be influenced by factors originating from both sides of caregiver-patient dyad. The aim of this study was to analyse direct and indirect interrelationships between perceived support and the sense of coherence in patient-caregiver dyad, and acceptance of illness in cancer patients.

DESIGN

Cross-sectional study.

METHODS

The study included 80 dyads composed of cancer patients and their caregivers. Only cancer patients undergoing oncological treatment at the time of the study, for at least 3 months but no longer than 12 months, were enrolled. All subjects completed perceived support subscale included in the Berlin Social Support Scales, sense of coherence-29 questionnaire to determine the sense of coherence and Acceptance of Illness Scale.

RESULTS

Compared to cancer patients, their caregivers presented with significantly lower levels of perceived social support and weaker sense of coherence. The sense of coherence in caregivers and patients was determined by their perceived support levels. The sense of coherence in caregivers turned out to be a key resource influencing acceptance of illness in cancer patients, both directly and indirectly, via their perceived social support and their sense of coherence.

CONCLUSIONS

The sense of coherence, an intrinsic psychological factor determined by social support, is an important determinant of illness acceptance. Functioning of cancer patients is also modulated by psychosocial characteristics of their caregivers.

RELEVANCE TO CLINICAL PRACTICE

Greater support offered to caregivers may substantially strengthen the sense of coherence in caregivers and cancer patients and, therefore, may improve the functioning of patient-caregiver dyad in a situation of neoplastic disease.

Partner's Perspective on Long-term Sexual Dysfunction After Prostate Cancer Treatment

OBJECTIVE

Prostate cancer is the most common type of male cancer in the United States and the negative effect of prostate cancer treatment on sexual function has been well documented. The objective of this study was to examine the long-term impact of sexual dysfunction on spouses or partners of prostate cancer survivors.

METHODS

A total of 742 spouses of prostate cancer survivors was mailed surveys by the Michigan Public Health Institute, of which 379 were returned (51%). Nine surveys were excluded owing to study ineligibility. Spouses responding to the survey completed a combination of modified items from the Sexual Adjustment Questionnaire and researcher-developed items.

RESULTS

Over 75% of spouses reported a decline in sex life quality after treatment. Communication about sexual issues between survivors and their health care providers was rated as good to excellent by 54.7% of partners, whereas 35.1% reported it as fair to poor. Approximately 60% of physicians initially recommended some form of sexual treatment. However, despite the persistence of sexual dysfunction, only 7% of the prostate cancer survivors were currently receiving treatment. Only 4.1% of health care providers referred the survivor to a sex therapist.

CONCLUSIONS

Physicians need to understand the importance of the open, ongoing communication with prostate cancer survivors about sexual issues because sexual dysfunction seems to continue indefinitely after completion of treatment. Research on the effectiveness of behavioral interventions in restoring sexual health is critically needed for this population, especially as first-line sexual aids and medications are often not satisfactory solutions.

The Impact of Husbands' Prostate Cancer Diagnosis and Participation in a Behavioral Lifestyle Intervention on Spouses' Lives and Relationships With Their Partners

BACKGROUND

A prostate cancer diagnosis affects the patient and his spouse. Partners of cancer patients are often the first to respond to the demands related to their husband's illness and thus are likely to be the most supportive individuals available to the patients. It is therefore important to examine how spouses react and handle their husband's prostate cancer diagnosis.

OBJECTIVE

The aim of this study was to explore how the prostate cancer diagnosis and the participation in their partners' behavioral lifestyle intervention program influenced the spouses' life, their relationship with their partner, and how they handle the situation.

METHODS

Interviews were recorded with 8 spouses of potential low-risk prostate cancer patients on active surveillance as part of a clinical self-management lifestyle trial.

RESULTS

We identified 3 phases that the spouses went through: feeling insecure about their situation, coping strategies to deal with these insecurities, and feeling reassured.

CONCLUSIONS

The framework of a clinical trial should include mobilizing spousal empowerment so that they can take on an active and meaningful role in relation to their husband's disease. The observations here substantiate that the framework of active surveillance in combination with a lifestyle intervention in 1 specific prostate cancer clinical trial can mobilize spousal empowerment.

IMPLICATIONS FOR PRACTICE

Creating well-designed clinical patient programs that actively involve the spouse appears to promote empowerment (meaning, self-efficacy, positive impact, and self-determination) in spouses. Spousal participation in clinical patient programs can give spouses relief from anxieties while recognizing them as a vital support for their husband.

The heart is a representation of life: an exploration of illness beliefs in couples living with atrial fibrillation

AIMS AND OBJECTIVES

To explore illness beliefs in couples where one spouse has atrial fibrillation.

BACKGROUND

Beliefs are the lenses through which we view the world, guiding our behaviour and constructing our lives. Couples evolve an ecology of beliefs from their interaction whereby their actions and choices arise from their beliefs. Atrial fibrillation is a common cardiac arrhythmia that has implications for both patients and partners. A couple's illness beliefs play an important role in convalescence and illness management, and no previous studies have explored illness beliefs in couples living with atrial fibrillation.

DESIGN

A qualitative hermeneutic design.

METHODS

Data collection constituted in-depth interviews with nine couples (patient and partner together). Hermeneutic philosophy as described by Gadamer was used to interpret and to understand illness beliefs in couples living with atrial fibrillation.

RESULTS

The findings revealed both core illness beliefs and secondary illness beliefs. From the core illness belief 'The heart is a representation of life', two secondary illness beliefs were derived: atrial fibrillation is a threat to life and atrial fibrillation can and must be explained. From the core illness belief 'Change is an integral part of life', two secondary illness beliefs were derived: atrial fibrillation is a disruption in our lives and atrial fibrillation will not interfere with our lives. Finally, from the core illness belief 'Adaptation is fundamental in life', two secondary illness beliefs were derived: atrial fibrillation entails adjustment in daily life and atrial fibrillation entails confidence in and adherence to professional care.

CONCLUSION

Couples' interaction has developed mutual illness beliefs regarding atrial fibrillation that guide them in their daily lives and influence their decisions. The adoption of a family-centred perspective in cardiovascular care settings is warranted.

Caregiver Illness Perception of Their Child's Early Childhood Caries

PURPOSE

The purpose of this case-control study was to evaluate the association between parent/caregivers' illness perception and early childhood caries (ECC).

METHODS

Parent/caregivers of children younger than six years old were recruited at the dental clinic of an urban children's hospital between June 2013 and September 2015. Cases were caregivers of ECC children; controls were caregivers of children without ECC. Caregivers completed the Illness Perception Questionnaire-Revised for Dental (IPQ-RD) assessing cognitive (identity, consequences, control, timeline, illness coherence, cause) and emotional representations of dental caries. Twelve IPQ-RD construct-specific summary scores were calculated; higher scores represented a less accurate perception. Logistic regression models examined the relationship between IPQ-RD constructs and ECC.

RESULTS

The sample included a total of 165 parent/caregivers: 54 had children (33 percent) without ECC; 111 had ECC children (67 percent). Two of the 12 constructs were related to ECC status. Controlling for caregiver age, education, race/ethnicity, and child age, caregivers of ECC children had a less accurate perception of the consequences of dental caries (odds ratio [OR] equals 2.24; 95 percent confidence interval [CI] equals 1.07 to 4.69) and a more accurate perception of the controllability of caries (OR equals 0.29; 95 percent CI equals 0.11 to 0.76) compared to caregivers of children without ECC.

CONCLUSION

Clinicians should emphasize the consequences and controllability of ECC to help caregivers self-manage their children's oral health.

Involvement in Decision Making and Satisfaction With Treatment Among Partners of Patients With Newly Diagnosed Localized Prostate Cancer

PURPOSE/OBJECTIVES

To examine partner involvement in treatment decision making for localized prostate cancer, congruence between partner involvement and patient preference, reasons for partner noninvolvement, and partner satisfaction with patient treatment
.

DESIGN

Cross-sectional exploratory study.

SETTING

100 counties in North Carolina.

SAMPLE

281 partners of men with newly diagnosed localized prostate cancer.

METHODS

Participants completed a phone survey. Logistic regression analyses were used.

MAIN RESEARCH VARIABLES

Partners' involvement in treatment decision making, partner satisfaction with treatment, activities of partner involvement, and reasons for noninvolvement.

FINDINGS

Of the 228 partners (81%) related to decision making, 205 (73%) were very satisfied with the treatment the patients received, and partner involvement was congruent with patient preference in 242 partners (86%). Partners reported several reasons for noninvolvement.

CONCLUSIONS

Most partners engaged in multiple activities during treatment decision making for localized prostate cancer and were satisfied with the patient's treatment. Partner involvement was mostly congruent with patient preference.

IMPLICATIONS FOR NURSING

Partners' active involvement in treatment decision making for localized prostate cancer (e.g., being involved in patients' conversations with doctors) should be encouraged and facilitated for those who prefer this type of decision making.

Illness representations, coping, and illness outcomes in people with cancer: a systematic review and meta-analysis

OBJECTIVE

Cancer is associated with negative health and emotional outcomes in those affected by it, suggesting the need to better understand the psychosocial determinants of illness outcomes and coping. The common sense model is the leading psychological model of self-regulation in the face of illness and assumes that subjective illness representations explain how people attempt to cope with illness. This systematic review and meta-analysis examines the associations of the common sense model's illness representation dimensions with health and coping outcomes in people with cancer.

METHODS

A systematic literature search located 54 studies fulfilling the inclusion criteria, with 38 providing sufficient data for meta-analysis. A narrative review of the remaining studies was also conducted.

RESULTS

Random-effects models revealed small to moderate effect sizes (Fisher Z) for the relations between illness representations and coping behaviors (in particular between control perceptions, problem-focused coping, and cognitive reappraisal) and moderate to large effect sizes between illness representations and illness outcomes (in particular between identity, consequences, emotional representations, and psychological distress). The narrative review of studies with insufficient data provided similar results.

CONCLUSIONS

The results indicate how illness representations relate to illness outcomes in people with cancer. However, more high-quality studies are needed to examine causal effects of illness representations on coping and outcomes. High heterogeneity indicates potential moderators of the relationships between illness representations and health and coping outcomes, including diagnostic, prognostic, and treatment-related variables. This review can inform the design of interventions to improve coping strategies and mental health outcomes in people with cancer.

Experiences of cancer patients in Poland throughout diagnosis and treatment

Previous studies have failed to explain why the mortality rate of cancer patients is higher in Poland than other countries in the European Union. We aimed to evaluate the health care system in Poland during the diagnosis and treatment of cancer. In this multicentre study, 125 cancer patients treated at 15 centres across Poland participated in focus group interviews in 2014. We identified and assessed crucial elements that affect a patients' experience from the early onset of symptoms, through to diagnosis and treatment. We found that the majority of patients were dissatisfied with the length of time taken to diagnose cancer. Throughout diagnosis, treatment and follow-up, patients reported a lack of communication from health care professionals. While dealings with oncologists and medical staff were viewed favourably, patients felt the cancer centres were not well organised. Patients recommended that having one doctor in charge of an individual's treatment and follow-up would improve patient care and well-being. A late cancer diagnosis may be contributing to the high mortality rate observed in Poland. In the future, new policies should be developed to reduce the time to cancer diagnosis, increase communication with health care professionals and improve the organisation of cancer care for patients.

Family Access to a Dentist Study (FADS): A multi-center randomized controlled trial

INTRODUCTION

Many low-income parent/caregivers do not understand the importance of cavity-free primary (baby) teeth and the chronic nature of dental caries (tooth decay). As a consequence, dental preventive and treatment utilization is low even when children are screened in schools and referred for care. This study aims to test a referral letter and Dental Information Guide (DIG) designed using the Common-Sense Model of Self-Regulation (CSM) framework to improve caregivers' illness perception of dental caries and increase utilization of care by children with restorative dental needs.

METHODS

A multi-site randomized controlled trial with caregivers of Kindergarten to 4th grade children in urban Ohio and rural Washington State will compare five arms: (1) CSM referral letter alone; (2) CSM referral letter+DIG; (3) reduced CSM referral letter alone; (4) reduced CSM referral letter+DIG; and (5) standard (control) referral. At baseline, children will be screened at school to determine restorative dental needs. If in need of treatment, caregivers will be randomized to study arms and an intervention packet will be sent home. The primary outcome will be dental care based on a change in oral health status by clinical examination 7 months post-screening (ICDAS sealant codes 1 and 2; restoration codes 3-8; extraction). Enrollment commenced summer 2015 with results in summer 2016.

CONCLUSION

This study uses the CSM framework to develop and test behavioral interventions to increase dental utilization among low-income caregivers. If effective this simple intervention has broad applicability in clinical and community-based settings.

Illness representations and psychological adjustment of Greek couples dealing with a recently-diagnosed cancer: dyadic, interaction and perception-dissimilarity effects

The aim was to examine the impact of the dyadic, interaction and dissimilarity effects of the illness representations on the psychological health of recently diagnosed cancer patients and spouses in Greece. The sample consisted of 298 individuals nested in 149 couples. Effects were examined with the Actor-Partner Interdependence Model. Both actor (i.e., within person) and partner (i.e., between partners) effects were detected for both patients' and spouses' psychological symptoms. The negative association of patients' psychological symptoms with their representations of illness coherence was weak at the higher and medium levels, and stronger at the lower levels of spouse corresponding representations. Patient-partner discrepancy in perceived illness consequences was associated with more psychological symptoms in patients. Adaptation to cancer is a dyadic process within the context of which patient and partner psychological well-being is affected by each other's understanding of illness. Thus, the parallel examination of the illness representations of both partners is needed from the early phases of the illness trajectory.

Illness perceptions within 6 months of cancer diagnosis are an independent prospective predictor of health-related quality of life 15 months post-diagnosis

OBJECTIVE

Studies have found that illness perceptions explain significant variance in health outcomes in numerous diseases. However, most of the research is cross-sectional and non-oncological. We examined, for the first time in breast, colorectal and prostate cancer patients, if cognitive and emotional illness perceptions near diagnosis predict future multidimensional health-related quality of life (HRQoL).

METHODS

UK-based patients (N = 334) completed the illness perception questionnaire-revised within 6 months post-diagnosis and the quality of life in adult cancer survivors scale 15 months post-diagnosis. Sociodemographic and clinical data were obtained from medical records. Hierarchical multiple regression analyses were conducted.

RESULTS

The sociodemographic and clinical factors collectively significantly predicted 8/12 HRQoL domains, although for 5/8 accounted for <10% of the variance. For all 12 HRQoL domains, illness perceptions collectively explained significant substantial additional variance (∆R(2) range: 5.6-27.9%), and a single illness perception questionnaire-revised dimension was the best individual predictor of 9/12 HRQoL domains. The consequences dimension independently predicted 7/12 HRQoL domains; patients who believed their cancer would have a more serious negative impact on their life reported poorer future HRQoL. The emotional representations and identity dimensions also predicted multiple HRQoL domains.

CONCLUSIONS

Future research should focus on realising the potential of illness perceptions as a modifiable target for and mediating mechanism of interventions to improve patients' HRQoL.

Partnership status affects the association between gastrointestinal symptoms and quality of life after radiation therapy for prostate cancer

PURPOSE

To study if partnership modifies the effect of gastrointestinal symptoms on quality of life after radiation therapy for prostate cancer.

MATERIAL AND METHODS

Using a study-specific questionnaire we conducted a cross-sectional follow-up of the occurrence gastrointestinal symptoms and quality of life after radiation therapy for prostate cancer. We obtained information from 874 prostate cancer survivors treated with radiation therapy at the Sahlgrenska University Hospital, Sweden between 1994 and 2006. In this paper we describe how partnership status affects the association between gastrointestinal symptoms and quality of life.

RESULTS

We found that unpartnered men with gastrointestinal symptoms reported a lower quality of life than unpartnered men without such symptoms. Unpartnered men with symptoms had an excess risk of low quality of life compared with unpartnered men without symptoms for those experiencing altered composition of stools, prevalence ratio 3.8 (95% CI 1.1-13.1), leakage, 3.6 (1.3-10.1), sensory bowel symptoms, 4.5 (1.6-12.8), and for urgency, 4.2 (1.2-15.1). We also found that unpartnered men with symptoms had an excess risk of low quality of life compared with partnered men with symptoms for those experiencing altered composition of stools, prevalence ratio 2.9 (95% CI 1.4-5.8), leakage 2.8 (1.2-6.4), sensory bowel symptoms 3.4 (1.5-7.4), urgency 2.6 (1.2-5.8), and for any gastrointestinal symptom 2.5 (1.3-4.9).

CONCLUSION

Unpartnered men may represent a group that is specifically vulnerable to the distressful effects of gastrointestinal symptoms after radiation therapy for prostate cancer.

Patient preference and the impact of decision-making aids on prostate cancer treatment choices and post-intervention regret

The number of prostate cancer survivors is rapidly growing in the Western world. As a result of better oncologic outcomes, more patients are living longer with the adverse effects of treatment, which can be both functional and psychological. Clinicians, in an era of shared decision-making, must not only cure the cancer, but also ensure that, after treatment, their patients experience the best quality of life and minimal post-treatment decisional regret. To participate in the decision-making process, men and their involved partners and family need to fully understand the relative benefits and harms of prostate cancer treatments.Patient preference studies indicate that men with prostate cancer are not well informed. Decision-making aids are a positive treatment adjunct both to convey information and to allow patients to explore their own beliefs and values during the decision-making process. The evidence suggests that decision-making aids better prepare patients for involvement in treatment decisions, but further studies are required to investigate the relationship between the use of decision-making aids and post-treatment decisional regret in prostate cancer.
