Perception of disease, dyadic coping, and the quality of life of oncology patients in the active treatment phase and their life partners: an approach based on the actor-partner interdependence model.

Objective: The aim of this study based on the Systemic Transactional Model was to examine the relationship between dyadic coping and (1) disease perception and (2) quality of life of a sample of cancer patients and their life partners. Method: This cross-sectional study included 138 oncological dyads. The following questionnaires were used: Stress Appraisal Measure, Dyadic Coping Inventory, and European Organisation for Research and Treatment of Cancer QLQ-C30. Data collected was analysed by applying the actor-partner interdependence model. Results: The perception of the disease as a threat as well as its centrality significantly negatively influences the positive forms of dyadic coping whilst the perception of the disease as a challenge has a significant positive influence on them. Dyadic coping does not influence symptoms but has significant influences on global health/quality of life. Conclusion: This study has highlighted new information regarding how couples cope with cancer. The results encourage the inclusion of the perception of the disease and dyadic coping in interventions that aim to improve the quality of life of cancer patients and their life partners.

Perception of disease, dyadic coping and the quality of life of oncology patients in the active treatment phase and their life partners: Study protocol of an approach based on the actor-partner interdependence model.

OBJECTIVES: Coping with cancer is a challenge for both patients and their life partners. Although there is evidence in the literature that supports the patient/partner mutual influence at the level of various psychological variables, it is still limited. This study, based on the Systemic Transactional Model, aims to investigate: 1) how the perception of disease of patients and their life partners influences their own dyadic coping and that of the other member of the couple; 2) the influence of the dyadic coping of patients and their partners on the quality of their own life and that of the other member of the couple. METHODOLOGY: This cross-sectional study aims to recruit 131 dyads consisting of oncology patients in the active treatment phase and their life partners. Perception of disease, dyadic coping and quality of life will be evaluated for each participant. The collected data will be analysed by applying the actor-partner interdependence model (APIM). CONCLUSION: The results highlighted in this study have the potential to help define future couple interventions that aim to improve quality of life of those facing cancer.

Optimism, Symptom Distress, Illness Appraisal, and Coping in Patients With Advanced-Stage Cancer Diagnoses Undergoing Chemotherapy Treatment.

PURPOSE/OBJECTIVES: To explore the relationships between optimism, self-efficacy, symptom distress, treatment complexity, illness appraisal, coping, and mood disturbance in patients with advanced-stage cancer.
. DESIGN: Cross-sectional study.
. SETTING: Smilow Cancer Hospital at Yale New Haven in Connecticut, an outpatient comprehensive cancer center.
. SAMPLE: A convenience sample of 121 adult patients with stages III-IV cancer undergoing active chemotherapy.
. METHODS: Participants completed common self-report questionnaires to measure variables. Treatment hours and visits were calculated from data retrieved from medical record review. Mediation and path analysis were conducted to identify direct and indirect pathways from the significant antecedent variables to mood disturbance.
. MAIN RESEARCH VARIABLES: Dispositional optimism, self-efficacy, social support, treatment complexity, symptom distress, illness appraisal, coping, and mood disturbance.
. FINDINGS: Greater optimism and self-efficacy were associated with less negative illness appraisal, less avoidant coping, and decreased mood disturbance. Conversely, greater symptom distress was associated with greater negative illness appraisal, greater avoidant coping, and greater mood disturbance. In the final model, optimism and symptom distress had direct and indirect effects on mood disturbance. Indirect effects were partially mediated by illness appraisal.
. CONCLUSIONS: Mood disturbance resulted from an interaction of disease stressors, personal resources, and cognitive appraisal of illness. Avoidant coping was associated with greater disturbed mood, but neither avoidant nor active coping had a significant effect on mood in the multivariate model. 
. IMPLICATIONS FOR NURSING: Illness appraisal, coping style, and symptom distress are important targets for intervention. Optimism is a beneficial trait and should be included, along with coping style, in comprehensive nursing assessments of patients with cancer.

A dyadic approach: applying a developmental-conceptual model to couples coping with chronic illness.

The purpose of the present study was to apply Berg and Upchurch's developmental-conceptual model toward a better understanding of how couples cope with chronic illness. Specifically, a model was hypothesized in which proximal factors (relational quality), dyadic appraisal (illness interference), and dyadic coping (partner support) influence adjustment (health condition management). The study was cross-sectional and included 308 dyads in which one partner has a chronic health condition. The actor partner interdependence model shows how congruence and noncongruence in relational quality, dyadic appraisal, and dyadic coping influence dyadic adjustment.

Cultural and social influences of negative illness appraisals in first-episode psychosis.

BACKGROUND: In the UK, there has been growing concern about the incidence and prognosis of psychosis in minority ethnic groups for a number of years. Negative self-appraisals after first-episode psychosis (FEP) are associated with post-psychotic depression, poor functioning and suicidality. In carers, appraisals of loss and decreased control are linked with high expressed emotion and relapse; however, as yet there has been no investigation as to how ethnicity and culture relate to these negative appraisals in FEP. AIMS: The study aims to investigate the occurrence of negative illness appraisals, for example, loss and shame, in FEP within different ethnic and social-cultural groups. In addition, it aims to explore influence of insight, recovery style and carers' appraisals in the development of negative appraisals. METHODS: There were 67 patients and 46 carers who completed reliable and valid measures on beliefs about illness, insight and recovery style. Data on ethnicity and deprivation were also collected. RESULTS: Black patients experienced significantly less loss, lack of control and entrapment than White, Asian and mixed ethnicity patients, yet these were not explained by lower levels of insight or recovery style. Patient's and carer's appraisals were highly correlated. CONCLUSION: Black patients, in spite of higher incidence and poorer outcome in FEP, experienced less loss and shame. Possible explanations, including a protective aspect of alternative health belief models, are explored. This area provides much scope for further investigation. Strong relationships between patient and carer appraisals indicate that family interventions are essential to improved clinical outcomes.
