Factors associated with caregiver strain among mothers and fathers of children with advanced cancer.

To characterize caregiver experiences in the context of advanced pediatric cancer by identifying individual (i.e., demographic factors, stress) and family context factors (i.e., family roles, social support) associated with caregiver strain. Families of children (ages 5-25) with advanced cancer (i.e., physician-estimated prognosis < 60%, relapsed/refractory disease) were recruited from a large children's hospital. Mothers (n = 55; 87% White) and fathers (n = 30; 83% White) reported on their caregiver strain, cancer-specific stress, general stress, social support, division of 7 family roles (e.g., medical care of ill child, household chores), and their satisfaction with each role. Parents reported moderate caregiver strain, cancer-specific stress, and general stress, and high social support and satisfaction with family roles. Fathers reported family roles were shared equally, whereas mothers reported either sharing roles or completing them independently. When accounting for income and partnership status, greater caregiver strain for mothers was associated with greater general stress, greater satisfaction with family roles, and lower social support. For fathers, greater caregiver strain was associated only with greater cancer-specific stress. In the context of advanced pediatric cancer, fathers may experience caregiver strain as cancer-specific stress increases, whereas mothers' strain may depend on broader family and social factors. Psychosocial providers should address general and cancer-specific stress within families, and provide resources for enhancing mothers' social support. Additional research is needed with larger, more diverse samples to inform future intervention approaches.

Impact of sociodemographic factors, stress, and communication on health-related quality of life in survivors of pediatric cancer.

While most research has largely focused on medical risks associated with reduced health-related quality of life (HRQOL) in survivors, sociodemographic and family factors may also play a role. Thus, we longitudinally examined sociodemographic factors and family factors associated with survivor HRQOL, including adolescent's cancer-specific stress, mother's general stress, and mother-adolescent communication. Mothers (N=80) and survivors (ages 10-23, N=50) were assessed 5years following initial diagnosis. Mothers completed measures regarding sociodemographic background adolescent's cancer-specific stress, mother's general stress, mother-adolescent communication, and adolescent HRQOL. Survivors also reported on their own HRQOL. Two hierarchical multiple regressions examined predictors of (a) mother's report of adolescent HRQOL, and (b) survivor's self-report of HRQOL. The final model predicting mother-reported adolescent HRQOL was significant, F(5,74)=21.18, p<.001, and explained 59% of the variance in HRQoL. Significant predictors included adolescent stress (β=-.37, p<.001), mothers' stress (β=-.42, p<.001), and communication (β=.19, p=.03). The final model predicting survivor-reported HRQOL was also significant, F(5,44)=5.16, p<.01 and explained 24% of the variance in HRQOL. Significant predictors included adolescent stress (β=-.37, p=.01) and communication (β=-.31, p=.04). Sociodemographic factors were not a significant predictor of HRQOL in any model. Family stress and communication offer potential points of intervention to improve HRQOL of pediatric cancer survivors from mother and survivor perspectives. While additional research is needed, healthcare professionals should encourage stress management and strong mother-child communication to enhance survivors' long-term HRQOL. Such interventions may be complimentary to efforts targeting the known sociodemographic factors that often affect health.

Stress and Coping in Patients With Cancer With Depression and Sleep Disturbance.

To evaluate for differences in global, cancer-specific, and cumulative life stress, as well as resilience and use of various coping strategies among five groups (no depression or sleep disturbance, no depression and moderate sleep disturbance, subsyndromal depression and very high sleep disturbance, moderate depression and moderate sleep disturbance [Both Moderate]; and high depression and very high sleep disturbance [Both High]). Patients (N = 1,331) receiving chemotherapy were recruited from outpatient oncology clinics. Measures of global, cancer-specific, and cumulative life stress, resilience, and coping were obtained. Differences were evaluated using parametric and nonparametric tests. Global and cancer-specific stress scores increased as joint profiles worsened. Both Moderate and Both High classes had cancer-specific stress scores suggestive of post-traumatic stress. Both Moderate and Both High classes reported higher occurrence rates for several stressful life events and higher use of disengagement coping. Both Moderate and Both High classes had resilience scores below the normative score for the United States. Clinicians need to screen vulnerable patients for post-traumatic stress disorder and implement interventions to reduce stress.

Common and distinct risk factors that influence more severe and distressing shortness of breath profiles in oncology outpatients.

Shortness of breath occurs in 10%-70% of oncology patients. Very little is known about interindividual variability in its severity and distress and associated risk factors. Using latent profile analyses (LPAs), purpose was to identify subgroups of patients with distinct severity and distress profiles for shortness of breath as single symptom dimensions. In addition, a joint LPA was done using patients' severity AND distress ratings. For each of the three LPAs, differences among the shortness of breath classes in demographic, clinical, symptom, stress, and resilience characteristics were evaluated. Patients completed ratings of severity and distress from shortness of breath a total of six times over two cycles of chemotherapy. All of the other measures were completed at enrollment (i.e., prior to the second or third cycle of chemotherapy). Separate LPAs were done using ratings of severity and distress, as well as a joint analysis using severity AND distress ratings. Differences among the latent classes were evaluated using parametric and nonparametric tests. For severity, two classes were identified (Slight to Moderate [91.6%] and Moderate to Severe [8.4%]). For distress, two classes were identified (A Little Bit to Somewhat [83.9%] and Somewhat to Quite a Bit [16.1%]). For the joint LPA, two classes were identified (Lower Severity and Distress [79.9%] and Higher Severity and Distress [20.1%]). While distinct risk factors were associated with each of the LPAs, across the three LPAs, the common risk factors associated with membership in the worse class included: a past or current history of smoking, poorer functional status, and higher comorbidity burden. In addition, these patients had a higher symptom burden and higher levels of cancer-specific stress. Clinicians can use the information provided in this study to identify high-risk patients and develop individualized interventions.

Adverse Childhood Experiences and Higher Levels of Stress Are Associated With the Co-occurrence of Cancer-Related Cognitive Impairment and Anxiety

We sought to identify subgroups of patients with distinct joint cancer-related cognitive impairment (CRCI) AND anxiety profiles and evaluate for differences in demographic and clinical characteristics, as well as levels of global stress, cancer-specific stress, cumulative life stress, and resilience. Patients (n = 1332) completed the Attentional Function Index and the Spielberger State Anxiety Inventory six times over two cycles of chemotherapy. Global, cancer-specific, and cumulative life stress and resilience were evaluated using Perceived Stress Scale, Impact of Event Scale-Revised, Life Stressor Checklist-Revised, and Connor-Davidson Resilience Scale, respectively. Latent profile analysis was used to identify subgroups of patients with distinct joint CRCI AND anxiety profiles. Differences were evaluated using parametric and nonparametric tests. Three classes were identified (ie, No CRCI and Low Anxiety [57.3%], Moderate CRCI and Moderate Anxiety [34.5%], and High CRCI and High Anxiety [8.2%]). All of the stress measures showed a dose-response effect (ie, as the CRCI AND anxiety profile worsened, scores for all three types of stress increased). The two highest symptom classes reported higher occurrence rates for six specific stressors (eg, emotional abuse, physical abuse, sexual harassment). Findings suggest that higher levels of co-occurring CRCI AND anxiety are associated with some common risk factors, as well as higher levels of stress and lower levels of resilience. Increased knowledge of modifiable risk factors and sources of stress associated with the co-occurrence of these two symptoms will assist clinicians to identify high-risk patients and implement individualized interventions.

Higher Lifetime Stress and Symptom Burden Contribute to the Occurrence of Shortness of Breath

Among four classes of patients with distinct shortness of breath profiles, evaluate for differences in levels of global, cancer-specific, and cumulative life stress, as well as resilience; evaluate for differences in the occurrence rates for various stressful life events, and evaluate for differences in the severity of common co-occurring symptoms. Outpatients (N = 1338) completed questionnaires six times over two cycles of chemotherapy. The occurrence of shortness of breath was assessed using the Memorial Symptom Assessment Scale. Latent class analysis was used to identify subgroups of patients with distinct shortness of breath profiles. Differences among the classes were evaluated using parametric and nonparametric tests. Shortness of breath classes were labeled based on their distinct occurrence trajectories: None (70.5%), Decreasing (8.2%), Increasing (7.8%), and High (13.5%). Compared to None class, Decreasing and High classes had higher global and cancer-specific stress scores. The High class reported higher occurrence rates for several adverse childhood experiences. Compared to None class, Decreasing and High classes had higher depression, anxiety, and morning fatigue scores and lower morning energy and cognitive function scores. Given the additive or synergistic relationships between stress, co-occurring symptoms, and shortness of breath, multimodal interventions that include stress management, exercise training, and/or symptom management may decrease shortness of breath in oncology patients.

Higher Stress in Oncology Patients is Associated With Cognitive and Evening Physical Fatigue Severity.

Cognitive and physical fatigue are common symptoms experienced by oncology patients. Exposure to stressful life events (SLE), cancer-related stressors, coping styles, and levels of resilience may influence the severity of both dimensions of fatigue. Evaluate for differences in global, cancer-specific, and cumulative life stress, as well as resilience and coping in oncology patients (n=1332) with distinct cognitive fatigue AND evening physical fatigue profiles. Latent profile analysis, which combined the two symptom scores, identified three subgroups of patients with distinct cognitive fatigue AND evening physical fatigue profiles (i.e., Low, Moderate, High). Patients completed measures of global, cancer-specific, and cumulative life stress as well measures of resilience and coping. Differences among the latent classes in the various measures were evaluated using parametric and nonparametric tests. Compared to Low class, the other two classes reported higher global and cancer-specific stress. In addition, they reported higher occurrence rates for sexual harassment and being forced to touch prior to 16 years of age. Compared to the other two classes, High class reported lower resilience scores and higher use of denial, substance use, and behavioral disengagement. To decrease both cognitive and evening physical fatigue, clinicians need to assess for relevant stressors and initiate interventions to increase resilience and the use of engagement coping strategies. Additional research is warranted on the relative contribution of various social determinants of health to both cognitive and physical fatigue in oncology patients receiving chemotherapy.

Trajectories of cancer-specific stress in cancer patients: a latent growth mixture analysis.

This study aimed to examine trajectories of cancer specific stress (CSS) over the course of a year, starting at the beginning of chemotherapy, and identify psychosocial factors that predicted trajectory class membership. Growth Mixture Modeling was used to identify distinct trajectories of CSS. Multinomial regression examined potential psychosocial predictors of trajectory membership. In the 4-class solution, all four trajectories demonstrated a decrease in CSS over the year but with differing intercepts and magnitudes of slopes. These were characterized as recovery, resilience, chronic, and severely chronic. The recovery group reported significantly higher insomnia scores than the resilient group. The chronic group reported significantly higher insomnia, higher depression, lower social support, and lower optimism than the resilient group. The chronic group reported significantly lower social support and higher depression than the recovery group. The findings provide information about psychosocial risk factors for CSS that can be screened for early intervention following diagnosis.

Exploration of the Relationships Between Stress and Distinct Pain and Sleep Disturbance Profiles in Patients Undergoing Chemotherapy.

Unrelieved pain and sleep disturbance are common symptoms in oncology patients. Increased stress may be an underlying cause for both symptoms. The purposes of this study were to identify subgroups of outpatients with distinct pain and sleep disturbance profiles and to evaluate differences among these subgroups in demographic and clinical characteristics. Differences in global stress, cancer-specific stress, and cumulative life stress, as well as resilience and coping, were evaluated. Patients (N = 1343) completed self-report questionnaires for demographic and clinical characteristics and stress, resilience, and coping. Latent profile analysis was used to identify subgroups of patients with distinct pain and sleep disturbance profiles. Differences among the subgroups were determined using parametric and nonparametric tests. Three distinct profiles were identified (ie, No Pain + Moderate Sleep Disturbance (SD) (27.6%), Moderate Pain + Moderate SD (38.6%), Severe Pain + High SD (33.8%)). Compared with the other 2 classes, Severe Pain + High SD class was younger, had fewer years of education, was more likely to be female, more likely to live alone, less likely to be employed, and had a higher level of comorbidity. This class had the highest stress scores and was more likely to report higher rates of adverse childhood experiences. Over 70% of our sample reported clinically meaningful levels of both symptoms, and 33.8% reported relatively high rates of adverse childhood experiences. Clinicians need to perform routine assessments, particularly of adverse childhood experiences, and initiate appropriate referrals.

Risk factors for worse anxiety trajectories among patients undergoing cancer chemotherapy

Patients undergoing chemotherapy for cancer often experience heightened anxiety. While receipt of chemotherapy occurs over multiple cycles, limited research has examined anxiety longitudinally. The purposes of this study, in a large sample of patients with breast, gynecological, gastrointestinal, or lung cancer, were to evaluate, over the course of two cycles of chemotherapy, for inter-individual differences in the trajectories of anxiety and identify associations between demographic, clinical, symptom, and psychological adjustment characteristics and initial levels and trajectories of anxiety. Patients with breast, gynecologic, lung, or gastrointestinal cancer (n = 1323) were assessed with the Spielberger State Anxiety Inventory (STAI-S) six times over two cycles of chemotherapy. At enrollment, patients completed self-report instruments assessing demographic, symptom, stress, and coping characteristics. We used hierarchical linear modeling to identify risk factors associated with initial levels and trajectories of state anxiety. Inter-individual differences in initial levels of anxiety were associated with functional status, sleep disturbance, morning fatigue, cognitive function, global and cancer-specific stress, resilience, and several coping characteristics (i.e., sense of coherence, acceptance, using emotional support, self-distraction, denial, venting, and self-blame). Demographic and clinical characteristics associated with interindividual differences in anxiety trajectories were age, employment status, and MAX-2 score. This study provides novel data on the course and predictors of anxiety during two cycles of chemotherapy among a large sample of patients with varied cancer types. Further research focused on risk factors for heightened levels of anxiety during chemotherapy may help point toward more effective interventions for this commonly experienced symptom.

Anxiety trajectories: An observational study of women undergoing chemotherapy for breast or gynecological cancer

While anxiety is prevalent among women who undergo chemotherapy for breast or gynecologic cancer, research on its predictors has focused primarily on cross-sectional evaluations or on assessments of anxiety prior to and after receipt of chemotherapy. Few studies have evaluated for predictors of inter-individual variability in levels of anxiety during chemotherapy. This study evaluated for inter-individual differences in anxiety across two cycles of chemotherapy and identified demographic, clinical, symptom, and psychological adjustment (e.g., stress, coping) characteristics associated with initial levels and trajectories of anxiety. Patients with breast (n=530) or gynecologic (n=233) cancer completed the Spielberger State Anxiety Inventory six times over two cycles of chemotherapy. At enrollment, self-report measures were used to assess demographic, symptom, stress, and coping characteristics. Hierarchical linear modeling was used to evaluate for risk factors associated with initial levels and trajectories of state anxiety. At enrollment, demographic, clinical, symptom, and psychological adjustment characteristics associated with inter-individual differences of anxiety were: marital status, functional status, sleep disturbance, cognitive function, global stress, cancer-specific stress, resilience, sense of coherence, and the coping strategies of venting and self-blame. Employment status and morning fatigue were the only characteristics associated with inter-individual differences in the trajectories of anxiety. Denial was the only characteristic associated with both initial levels and the trajectories of anxiety. A variety of patient characteristics predicted initial levels of anxiety. Fewer characteristics predicted trajectories of anxiety. Identification of specific risk factors, such as avoidant coping, suggests the need for targeted interventions among higher-risk patients.

Associations Between Demographic, Clinical, and Symptom Characteristics and Stress in Oncology Patients Receiving Chemotherapy.

Patients undergoing cancer treatment experience global stress and cancer-specific stress. Both types of stress are associated with a higher symptom burden. In this cross-sectional study, we used a comprehensive set of demographic, clinical, and symptom characteristics to evaluate their relative contribution to the severity of global and cancer-specific stress. Patients (N = 941) completed study questionnaires before their second or third cycle of chemotherapy. Consistent with our a priori hypothesis, we found both common and distinct characteristics associated with higher levels of global stress and cancer-specific stress. A significant proportion of our patients had scores on the Impact of Event Scale-Revised suggestive of subsyndromal (29.4%) or probable (13.9%) posttraumatic stress disorder. Four of the 5 stepwise linear regression analyses for the various stress scales explained between 41.6% and 54.5% of the total variance. Compared with various demographic and clinical characteristics, many of the common symptoms associated with cancer and its treatments uniquely explained a higher percentage of the variance in the various stress scales. Symptoms of depression made the largest unique contribution to the percentage of total explained variance across all 5 scales. Clinicians need to assess for global stress, cancer-specific stress, and depression in patients receiving chemotherapy. Patients may benefit from integrative interventions (eg, mindfulness-based stress reduction, cognitive behavioral therapy, acupuncture) that simultaneously address stress and symptoms commonly associated with cancer and its treatments.

Higher levels of stress and different coping strategies are associated with greater morning and evening fatigue severity in oncology patients receiving chemotherapy.

PurposeA cancer diagnosis and associated treatments are stressful experiences for most patients. Patients’ perceptions of stress and their use of coping strategies may influence fatigue severity. This study extends our previous work describing distinct profiles of morning (i.e., Very Low, Low, High, and Very High) and evening (i.e., Low, Moderate, High, and Very High) fatigue in oncology patients by evaluating for differences in stress and coping strategies among these fatigue classes.MethodsThis longitudinal study evaluated for changes in morning and evening fatigue in oncology patients (n = 1332) over two cycles of chemotherapy (CTX). Patients completed measures of cumulative exposure to stressful life events (SLEs) (i.e., the Life Stressor Checklist-Revised), general stress (i.e., Perceived Stress Scale [PSS]), cancer-specific stress (i.e., Impact of Event Scale-Revised [IES-R]), and coping strategies (i.e., Brief Cope). Differences among the latent classes were evaluated using analyses of variance, Kruskal-Wallis, or chi-square tests.ResultsPatients in both the Very High morning and evening fatigue classes reported higher numbers of and a higher impact from previous SLEs and higher PSS scores than the other fatigue classes. The IES-R scores for the Very High morning fatigue class met the criterion for subsyndromal PTSD. Patients in the Very High evening fatigue class used a higher number of engagement coping strategies compared with the Very High morning fatigue class.ConclusionsOur findings suggest that interventions to reduce stress and enhance coping warrant investigation to decrease fatigue in patients undergoing CTX.Electronic supplementary materialThe online version of this article (10.1007/s00520-020-05303-5) contains supplementary material, which is available to authorized users.

Newly diagnosed patients with advanced non-small cell lung cancer: A clinical description of those with moderate to severe depressive symptoms

ObjectivesThe aims of this observational study were to 1) accrue newly diagnosed patients with advanced-stage non-small cell lung cancer (NSCLC) awaiting the start of first-line treatment and identify those with moderate to severe depressive symptoms and, 2) provide a clinical description of the multiple, co-occurring psychological and behavioral difficulties and physical symptoms that potentially exacerbate and maintain depressive symptoms. Materials and methodsPatients with stage IV NSCLC (N = 186) were enrolled in an observational study (ClinicalTrials.gov Identifier: NCT03199651) and completed the American Society of Clinical Oncology-recommended screening measure for depression (Patient Health Questionnaire-9 [PHQ-9]). Individuals with none/mild (n = 119; 64 %), moderate (n = 52; 28 %), and severe (n = 15; 8 %) depressive symptoms were identified. Patients also completed measures of hopelessness, generalized anxiety disorder (GAD) symptoms, stress, illness perceptions, functional status, and symptoms. ResultsPatients with severe depressive symptoms reported concomitant feelings of hopelessness (elevating risk for suicidal behavior), anxiety symptoms suggestive of GAD, and traumatic, cancer-specific stress. They perceived lung cancer as consequential for their lives and not controllable with treatment. Pain and multiple severe symptoms were present along with substantial functional impairment. Patients with moderate depressive symptoms had generally lower levels of disturbance, though still substantial. The most salient differences were low GAD symptom severity and fewer functional impairments for those with moderate symptoms. ConclusionsDepressive symptoms of moderate to severe levels co-occur in a matrix of clinical levels of anxiety symptoms, traumatic stress, impaired functional status, and pain and other physical symptoms. All of the latter factors have been shown, individually and collectively, to contribute to the maintenance or exacerbation of depressive symptoms. As life-extending targeted and immunotherapy use expands, prompt identification of patients with moderate to severe depressive symptoms, referral for evaluation, and psychological/behavioral treatment are key to maximizing treatment outcomes and quality of life for individuals with advanced NSCLC.

Distinct Stress Profiles Among Oncology Patients Undergoing Chemotherapy

ContextCancer and its treatment are inherently stressful and stress impacts important patient outcomes. Patients vary considerably in their response to stress. Understanding this variability requires a patient-centered multidimensional approach. ObjectivesThe objectives of this study were to identify and characterize patient subgroups with distinct multidimensional stress profiles (stress appraisal, exposure, and adaptation) during cancer treatment. MethodsAmong 957 patients undergoing chemotherapy for breast, gastrointestinal, gynecological, or lung cancer, latent profile analysis was performed to identify patient subgroups using concurrent evaluations of global (Perceived Stress Scale) and cancer-specific (Impact of Events Scale–Revised) stress, lifetime stress exposure (Life Stressor Checklist–Revised), and resilience (Connor-Davidson Resilience Scale-10). ResultsThree latent classes were identified: “Normative” (54.3%; intermediate global stress and resilience, lower cancer-related stress, lowest life stress); “Stressed” (39.9%; highest global and cancer-specific stress scores, lowest resilience, most life stress); and “Resilient” (5.7%; lowest global stress, cancer-specific stress comparable to Normative class, highest resilience, intermediate life stress). Characteristics that distinguished the Stressed from the Normative class included the following: younger age, female gender, lower socioeconomic status, unmarried/partnered, living alone, poorer functional status, and higher comorbidity burden. Compared to Stressed patients, Resilient patients were more likely to be partnered, to not live alone, and had a higher functional status. No demographic or clinical characteristics differentiated Normative from Resilient patients. Exposure to specific life stressors differed significantly among the classes. ConclusionA subset of patients warrants intensive psychosocial intervention to reduce stress and improve adaptation to cancer. Intervention efforts may be informed by further study of Resilient patients.

Identifying risk factors for depression and anxiety symptoms in patients with chronic lymphocytic leukemia.

This study assessed whether empirically supported risk factors can identify future depression and anxiety symptoms in a specific cancer type, chronic lymphocytic leukemia (CLL). Patients enrolled in a CLL treatment clinical trial (N = 106) participated at baseline following informed consent and prior to treatment initiation. Risk factors with empirical support (personal or family psychiatric history, recurrent, advanced or progressive disease, low socioeconomic status, gender, medical comorbidities, and single marital status) and additional risk factors (cancer-specific stress, social contacts, negative life events, absolute lymphocyte counts, treatment group, and fatigue) were measured at baseline to predict depression and anxiety symptoms at 12months. Data show 14% (n = 15) and 12% (n = 13) of patients experienced moderate-severe depression and anxiety symptoms, respectively. Multiple linear regression analyses found medical comorbidities predicted 12-month anxiety symptoms (p < 0.05). Also, negative life events predicted depression and anxiety symptoms and fatigue predicted depression symptoms (p < 0.05). Empirically supported risk factors associated with depression and anxiety symptoms are limited in predicting future depression and anxiety symptoms beyond initial screening in patients with CLL. In addition to levels of depression and anxiety symptoms at baseline, negative life events, higher levels of fatigue, and greater medical comorbidities were associated with future depression or anxiety symptoms in patients with CLL.

Effect of Nursing Intervention Program on Quality of Life Improvement for Women Undergoing Gynecological and Breast Cancer Treatment

Background: Breast and gynecological cancer are the most common type of cancer in women and need rehabilitation programs to improve QOL. Aim of the study was to assess the effectiveness of nursing intervention program on QOL improvement in women undergoing treatment for gynecological and breast cancer. Study design: A quasi experimental study design. Sample and settings: A randomly selected sample of 100 women diagnosed with gynecological and breast cancer who attended the oncology institute, and divided to two groups, the study group and control group. Tool structured interview questionnaire included socio-personal data, oncology treatment side effects record, reproductive concerns scale, female sexual function index, impact of event scale cancer specific stress, and functional assessment of cancer therapy-general. Results: Quality of life of the intervention group with breast and gynecological cancer have been improved under the influence of the nursing intervention program. Conclusion and Recommendations: The nursing intervention program showed evidence of improved QOL, with a reduction in the sexual dysfunction, and lower stress levels. It was suggested to heighten awareness about the breast and gynecological cancer treatment-related side effects among the nursing staff.

Post-traumatic growth in breast cancer: how and when do distress and stress contribute?

While several theoretical models provide explanation for the genesis and development of post-traumatic growth (PTG) in the aftermath of stressful events, empirical evidence regarding the predictors and consequences of PTG in breast cancer patients in active treatment and early survivorship is inconclusive. This study, therefore, examines the role of distress and stress as predictors and outcomes of PTG in women with breast cancer over an 18-month period. These effects are tested in two structural equation models that track pathways of PTG in a sample of 253 recently diagnosed women. Questionnaires were completed at diagnosis and at 4 follow-up time points assessing cancer-specific stress (Impact of Events Scale), global stress (Perceived Stress Scale), and depression and anxiety (Hospital Anxiety and Depression Scale). Post-traumatic growth (Silver Lining Questionnaire) was assessed at follow-up time points. Cancer-specific stress was related to higher PTG concurrently and longitudinally. Anxiety was related concurrently to higher PTG, but overall general distress had minimal impact on PTG. Global stress was inversely related to PTG. Positive growth at 6months was associated with subsequent reduction in stress. This study showing that early stage higher cancer-specific stress and anxiety were related to positive growth supports the idea that struggle with a challenging illness may be instrumental in facilitating PTG, and findings show positive implications of PTG for subsequent adjustment.

Individual differences in physical symptom burden and psychological responses in individuals with chronic lymphocytic leukemia.

Chronic lymphocytic leukemia (CLL) is an incurable illness, with some patients requiring no treatment until disease progression. Burden from physical symptoms has been associated with depression, anxiety, and stress in cancer patients. Additionally, patient factors, i.e., individual differences, have been associated with worse psychological outcomes. There are few psychological studies of CLL, with no examination of individual differences. A cross-sectional design studied the covariation of symptom burden with depressive and anxiety symptoms and cancer-specific stress, and tested patients' individual differences as predictors and as moderators. CLL patients (N = 112) receiving active surveillance participated. They were Caucasian (100%) and predominately male (55%) with a mean age of 61; most (62.5%) had stage 0 disease. A composite measure of physical symptom burden (CLL symptoms, fatigue, pain, impaired functional status) was tested as a predictor of psychological responses. Individual differences in psychiatric history and social support were tested as moderators. Using multiple linear regression, greater symptom burden covaried with higher levels of depressive and anxiety symptoms and cancer stress (ps < .05). Those with a psychiatric history, low social support, and low relationship satisfaction with one's partner reported greater symptom burden and more psychological symptoms and stress (ps < .05). Findings suggest that CLL patients in surveillance with a psychiatric history and/or low social support are at risk for greater distress when coping with high symptom burden. These new data clarify the experience of CLL surveillance and identify characteristics of patients with heightened risk for symptom burden, stress, and anxiety or depressive symptoms.

The relation of illness perceptions to stress, depression, and fatigue in patients with chronic lymphocytic leukaemia

Objective: Chronic lymphocytic leukaemia (CLL) is the most prevalent adult leukaemia and is incurable. The course and treatment of CLL is unique and characterised by repeated cycles of treatment, stable disease and relapse. Utilising a Self-Regulatory Model framework, we examined the relationship between patients’ illness perceptions and cancer-specific stress, depressive symptoms and fatigue. Our aim was to test illness perceptions as predictors of these outcomes when variance due to disease and treatment variables was controlled.Design: Data were collected on 147 patients with relapsed/refractory CLL as they entered a phase II clinical trial of an investigational medication at a university affiliated, National Cancer Institute designated comprehensive cancer center.Main outcome measures: Cancer-specific stress, depressive symptoms and fatigue interference.Result:. Hierarchical multiple regression was used. Consequences and emotional representation were related to all outcomes (ps < .01). Illness concern was related to cancer-specific stress (p < .01), and identity was related to fatigue interference (p < .01). All relationships were observed while controlling for number of previous CLL therapies received.Conclusion: Illness perceptions are related to cancer-specific stress, depressive symptoms and fatigue interference in relapsed/refractory CLL. Interventions targeted at restructuring maladaptive illness perceptions may have clinical benefit in this population.
