“…As expected, higher levels of psychological distress were also associated with a greater emotional impact of cancer, more severe consequences of cancer, a more chronic perceived timeline of cancer, and more perceived cancer symptoms . Finally, a better quality of life was associated with less perceived cancer symptoms, a less cyclical timeline, less severe consequences of cancer, less emotional impact of cancer, and greater perceived personal and treatment control over cancer …”

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 selfregulation 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. ConclusionsThe 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. | Illness representations and the common sense modelThe common sense model of self-regulation of health and illness (CSM) 9 is a widely accepted psychological model of the processes underlying health and coping in people with chronic illness.

“…The usefulness and validity of the CS-SRM model has been confirmed by numerous studies on patients suffering from several chronic diseases, such as diabetes, cardiovascular disease, asthma, and cancer (Petrie and Weinman, 1997; Cameron and Leventhal, 2003; French et al, 2013; Mickevičienë et al, 2013). Several studies on different chronic illnesses have confirmed the mediating role of coping strategies in the relationship between illness representations and outcomes, such as mood, quality of life, and patients’ satisfaction (Diefenebach and Leventhal, 1996; Leventhal et al, 2001; Rutter and Rutter, 2002; Hagger and Orbell, 2003; Llewellyn et al, 2007; Gould et al, 2010; Catunda et al, 2016).…”

Illness Representations of HIV Positive Patients Are Associated with Virologic Success

et al. 2016

Introduction: It is important for HIV positive patients to be engaged in their care and be adherent to treatment in order to reduce disease progression and mortality. Studies found that illness representations influence adherence through the mediating role of coping behaviors. However, no study has ever tested if patient engagement to the visits mediate the relationship between illness perceptions and adherence. This study aimed to explore illness representations of HIV positive patients and test the hypothesis that illness representations predict adherence through the mediating role of a component of behavioral engagement.Methods: HIV-positive patients treated with highly active antiretroviral therapy (HAART) for at least one year and presenting to a check-up visit were eligible to participate in the study. Patients completed the Illness Perception Questionnaire-Revised. Behavioral engagement was measured based on the patients’ clinical attendance to the check-up visits; adherence to HAART was measured by viral load. Undetectable viral load or HIV-RNA < 40 copies/ml were considered indexes of virologic success.Results: A total of 161 patients participated in the study. Most of them coherently attributed the experienced symptoms to HIV/HAART; perceived their condition as chronic, stable, coherent, judged the therapy as effective, and attributed their disease to the HIV virus and to their behavior or bad luck. The majority of patients (80.1%) regularly attended check-up visits and 88.5% of them reached virologic success. The mediation model did not show good fit indexes. However, a significant direct effect of two independent variables on virologic success was found. Specifically, the perception that the disease does not have serious consequences on patient’s life and the prevalence of negative emotions toward HIV were associated with virologic success. On the contrary, the patient’s perception that the disease has serious consequences on his/her life and the prevalence of positive emotions were associated with virologic failure. This model showed good fit indexes (CFI = 1; TLI = 1; RMSEA = 0.00; and WRMSR = 0.309).Discussion: Results do not support the mediating role of behavioral engagement in the relationship between illness representations and adherence. As perception of serious consequences coupled with positive emotions are directly associated with virologic failure, clinicians should take them into account to promote treatment adherence.

Experiences of cancer patients in Poland throughout diagnosis and treatment

2016

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.
