A review of the literature on resilience in the adolescent with cancer: Part II

Towards a Transversal Definition of Psychological Resilience: A Literature Review

Background and objectives: This paper addresses psychological resilience, a multidisciplinary theoretical construct with important practical implications for health sciences. Although many definitions have been proposed in several contexts, an essential understanding of the concept is still lacking up to now. This negatively affects comparisons among research results and makes objective measurement difficult. The aim of this review is to identify shared elements in defining the construct of resilience across the literature examined in order to move toward a conceptual unification of the term. Materials and methods: A literature review was performed using the electronic databases 'PubMed' and 'PsycINFO'. Scientific studies written in English between 2002 and May 2019 were included according to the following key terms: 'Psychological', 'resilience', and 'definition'. Results: The review identifies five macro-categories that summarize what has been reported in the recent literature concerning the resilience phenomenon. They serve as a preliminary and necessary step toward a conceptual clarification of the construct. Conclusions: We propose a definition of psychological resilience as the ability to maintain the persistence of one's orientation towards existential purposes. It constitutes a transversal attitude that can be understood as the ability to overcome the difficulties experienced in the different areas of one's life with perseverance, as well as good awareness of oneself and one's own internal coherence by activating a personal growth project. The conceptual clarification proposed will contribute to improving the accuracy of research on this topic by suggesting future paths of investigation aimed at deeply exploring the issues surrounding the promotion of resilience resources.

Psychological impact of lymphoma on adolescents and young adults: not a matter of black or white

PURPOSE

The purpose of the study is to examine differences in perceived impact of cancer (IOC) between adolescents and young adults (AYAs; 18-35 years at cancer diagnosis), adults (36-64 years) and elderly (65-84 years) with a history of (non-)Hodgkin lymphoma. Furthermore, to investigate the association of socio-demographic, clinical and psychological characteristics with IOC; and the association between IOC and health-related quality of life (HRQoL) among AYAs only.

METHODS

This study is part of a population-based PROFILES registry survey among lymphoma patients diagnosed between 1999 and 2009. Patients (n = 1.281) were invited to complete the IOCv1 and EORTC-QLQ-C30 questionnaires. Response rate was 67 % (n = 861).

RESULTS

AYA lymphoma survivors scored higher on the positive IOC summary scale, compared to adult and elderly patients (p < 0.001), while no significant differences were observed for negative IOC. Among AYAs, females, survivors with a partner, and survivors with elevated psychological distress levels scored significantly higher on the negative IOC summary scale. The negative IOC summary scale was negatively associated with all EORTC QLQ-C30 functioning scales (β ranging from -0.39 to -0.063; p < 0.05). The positive IOC summary scale was negatively associated with the EORTC QLQ-C30 subscale 'Emotional functioning' (β = -0.24; p < 0.05).

CONCLUSION

AYA, adult and elderly with a history of (non-)Hodgkin lymphoma experienced different types of IOC in terms of positive and negative aspects.

IMPLICATIONS FOR CANCER SURVIVORS

Although AYAs experience a more positive IOC compared to older survivors, some AYAs experience more negative IOC and may require developmentally appropriate interventions to address their specific concerns.

The Adolescent/Young Adult Experience

Adolescents and young adults with cancer (AYA) have strikingly poorer outcomes when compared to younger or older patients. Contributing reasons include low rates of enrollment in clinical trials and the “invisibility” of the AYA perspectives in research reports. We recommend a shift in research perspectives away from function-based studies that focus on morbidity and mortality outcomes to meaning-based models that will very likely rely upon qualitative methods and findings as the basis for developing psychosocial interventions that are sensitive to the AYA cancer experience. In addition, research on positive health concepts such as hope, spirituality, and positive coping are recommended as a way to learn about the effective strategies used by AYA to adjust to the cancer experience.

Profiles of Dispositional Expectancies and Affectivity Predict Later Psychosocial Functioning in Children and Adolescents With Cancer

OBJECTIVE

Examined how individual differences in disposition among pediatric cancer patients predict their later psychosocial functioning.

METHODS

Patients aged 8-17 years (N = 223) reported on their disposition at baseline. One and three years later, self-reports and parent reports of patient psychosocial functioning were obtained. Latent profile analysis was used to identify subgroups that differed on baseline disposition and to compare them on later outcomes.

ESULTS

Three groups were identified: The "Positive" group (59%) had high optimism and positive affectivity and low pessimism and negative affectivity; the "Moderate" group (39%) had a similar profile, with less exaggerated scores; a small, "Negative" group (2%) had the opposite profile (low optimism/positive affectivity; high pessimism/negative affectivity). These groups differed in psychosocial functioning at follow-up, generally in expected directions.

CONCLUSIONS

Most patients have a disposition that may be protective. A small minority at high risk for maladjustment is distinguished by their disposition.

Psychosocial barriers and facilitators to clinical trial enrollment and adherence for adolescents with cancer

Adolescents (aged 15-19 years) have not experienced the same survival gains as children and older adults diagnosed with cancer. Poor clinical trial enrollment and adherence rates among adolescents may account for some of this disparity. Although biological, regulatory, systemic, and practice-related challenges to clinical trial enrollment and adherence have been examined, studies of psychosocial factors, which can serve as barriers or facilitators to enrollment and adherence, are limited. To bring attention to these psychological factors, we reviewed existing literature on psychosocial barriers and facilitators that can affect an adolescent's decision to enroll and adhere to a clinical trial. We also provide potential strategies to address psychosocial factors affecting clinical trial accrual and adherence.

Physical symptoms, perceived social support, and affect in adolescents with cancer

Treatment for cancer among adolescents is often more intense and lasts longer than treatment for older or younger patients. It typically causes pain, fatigue, and nausea and affects social and emotional well-being. This study examined the relationships among demographics, physical symptoms, perceived social support from friends and family, and affect (positive and negative) in 102 adolescents (age 13-19) with cancer using correlational analyses. Additionally, perceived social support was explored as a mediator and moderator of the relationship between physical symptoms and affect using regression. Females reported significantly lower friend support and higher negative affect compared to males. Minority participants were more likely to endorse physical symptoms and less negative affect compared to White respondents. Higher report of physical symptoms was significantly related to greater negative affect, whereas higher perceived social support from friends was related to higher positive affect. Adolescents consistently reported high levels of social support from family and friends. Additionally, adolescents tended to report average levels of positive affect and low levels of negative affect compared to healthy populations. No significant mediation or moderation effects were found. This research highlights that females and minorities, and those with greater physical symptoms, may be more vulnerable to poor adjustment to cancer during adolescence. However, overall this study lends support to the notion that adolescents with cancer are an especially resilient population, as these patients endorsed generally high levels of social support and positive affect, with low levels of negative affect.

The meaning of surviving cancer for Latino adolescents and emerging young adults

Adolescent and young adult (AYA) survivors of cancer are an understudied population with unique developmental and medical needs that extend well beyond their active treatment. Survivors diagnosed as AYAs may experience both physical and emotional late effects. In particular, the experiences of Latino cancer survivors have not been explored. The purpose of this study was to conduct interviews with AYA Latino cancer survivors to inform professionals working with these survivors. A hermeneutic phenomenological approach was selected based on the focus on experiences and meanings of Latino adolescents' cancer survivorship. Phenomenology allows for understanding the subjective meaning and lived experience of populations that are understudied or marginalized. In-depth interviews were conducted with participants. Enrolled in the study were Latino AYAs between the ages of 14 and 21 years, after treatment. Interviews revealed 7 themes regarding the experience and meaning of survivorship for this population: gratitude, humor/positive attitude, empathy for younger children with cancer, God and faith, cancer happens for a reason/cancer changed my life, familial support, and staff relationships. Latino AYA cancer survivors develop meaning out of unique cancer experiences. Programs need to be developed specifically to address Latino adolescents and young adult survivors of cancer.

Attitudes of adolescent cancer survivors toward end-of-life decisions for minors

OBJECTIVES

The present study aimed to investigate the attitudes of adolescent cancer survivors toward end-of-life decisions with life-shortening effects, including nontreatment decisions (NTDs), intensified alleviation of pain and symptoms (APS), and euthanasia, and the influence of illness experience on these attitudes.

METHODS

Adolescent cancer survivors were interviewed with a structured questionnaire using hypothetical case descriptions. The results were compared with a study of 1769 adolescents without experience of chronic illness.

RESULTS

Eighty-three adolescents, 11 to 18 years of age, were interviewed. In terminal situations, 70% to 90% found requests for NTDs acceptable, 84% requests for APS, and 57% to 64% requests for euthanasia. Requests for end-of-life decisions were less acceptable in nonterminal situations, where 28% found requests for NTDs acceptable, 39% to 47% requests for APS, and 11% to 21% requests for euthanasia. Frequently cited reasons for holding back physicians from administering a lethal drug to a child were the child not being well informed about his or her condition (92%) and the parents' opinion not being asked (92%). Compared with adolescents without experience with chronic illness, cancer survivors were more accepting toward requests for NTDs and APS in terminal situations.

CONCLUSIONS

Adolescent cancer survivors, like other adolescents, want to be involved in medical decision-making at the end of life. They value autonomous decision-making, without excluding parents from the process. The experience of living through a life-threatening illness can alter adolescents' attitudes toward requests for NTDs and APS.

The influence of resilience on fatigue in cancer patients undergoing radiation therapy (RT)

PURPOSE

The primary goal of the study was to determine if resilience influences fatigue in a consecutive sample of cancer patients treated with radiotherapy (RT) at the beginning and at the end of the treatment.

METHODS

Out of an initial sample of 250 patients, 239 could be assessed at the beginning of their RT. Two hundred and eight patients were reassessed at the end of RT 4-8 weeks later. Measures comprised the Resilience Scale (RS), the Multidimensional Fatigue Inventory (MFI), and the SF-12 as a measure of health related Quality of Life (QoL). Medical data were continuously registered.

RESULTS

As hypothesized, the sample revealed higher scores in the MFI and lower scores in the SF-12 than normative samples. Resilience scores were higher than in the norm population. Fatigue increased during RT. Using multiple regression analyses, fatigue scores at the beginning of treatment were shown to be higher in inpatients and patients undergoing palliative treatment. Initial fatigue was best predicted by the patients' initial resilience scores. Changes of fatigue scores during RT depended on initial scores, decrease in Hb and the patients' experience with RT. Resilience could not be determined as a predictor of changes in fatigue during RT.

CONCLUSIONS

The study confirmed that fatigue is an important problem among RT patients. Resilience turned out to powerfully predict the patients' fatigue at least early in RT. This result is in line with other studies, showing resilience to be an important psychological predictor of QoL and coping in cancer patients. On the other hand, resilience seems to have little influence on treatment related fatigue during RT.

A phenomenologic study of fatigue in adolescents receiving treatment for cancer

PURPOSE/OBJECTIVES

To generate a detailed description of how adolescents with cancer manage their daily lives and the way in which fatigue affects this.

DESIGN

Phenomenologic.

SETTING

A pediatric oncology unit at a regional cancer center in the United Kingdom.

SAMPLE

A convenience sample of adolescents (N = 8), aged 16-19 years and with hematologic or solid tumors, who currently were undergoing primary treatment.

METHODS

Semistructured interviews were conducted using 11 open-ended questions.

MAIN RESEARCH VARIABLES

Adolescents' perceptions of fatigue, well-being, and ability to maintain normal activities.

FINDINGS

Adolescents reported fatigue as overwhelming and embedded in a syndrome of symptoms and emotions associated with the illness itself and with treatment. Fatigue had a significant effect on physical, psychological, and social well-being, placing an extra burden on adolescents who were striving for normality.

CONCLUSIONS

Equipped with a rich description of fatigue, clinicians will be better prepared to initiate strategies congruent with their own work settings and particular patients.

IMPLICATIONS FOR NURSING

The findings should enable healthcare professionals to construct a more accurate and perceptive picture of the needs of particular individuals, highlighting those that may be amenable to intervention.

The development and psychometric evaluation of the Brief Resilient Coping Scale

This article introduces the Brief Resilient Coping Scale (BRCS), a 4-item measure designed to capture tendencies to cope with stress in a highly adaptive manner. Two samples of individuals with rheumatoid arthritis (ns = 90 and 140) provide evidence for the reliability and validity of the BRCS. The BRCS has adequate internal consistency and test-retest reliability. Convergent validity of the scale is demonstrated by predictable correlations with measures of personal coping resources (e.g., optimism, helplessness, self-efficacy), pain coping behaviors, and psychological well-being. Resilient coping, as assessed by the BRCS, also buffers the effects of high levels of arthritis-related and non-arthritis-related stressors on depressive symptoms. The sensitivity of the BRCS to changes associated with a cognitive-behavioral intervention is also demonstrated. The BCRS may be useful for identifying individuals in need of interventions designed to enhance resilient coping skills.
