A sequential multiple assignment randomized trial of symptom management for cancer survivors during treatment and their informal caregivers.

CONTEXT: Many cancer survivors and their informal caregivers experience multiple symptoms during the survivor's treatment. OBJECTIVE: Test relative effectiveness and optimal sequencing of two evidence-based interventions for symptom management. METHODS: In this sequential multiple assignment randomized trial (SMART), survivors of solid tumors with elevated depression or anxiety and their caregivers as dyads were initially randomized after baseline assessment in a 3:1 ratio to the Symptom Management and Survivorship Handbook (SMSH, N = 277 dyads) intervention or SMSH plus 8 weeks of telephone interpersonal counseling (TIPC, N = 97 dyads). After 4 weeks, survivors who were not responding (no improvement or worsening score on depression and/or anxiety item) to SMSH only and their caregivers were re-randomized to continue with SMSH alone (N = 44 dyads) to give it more time or to SMSH + TIPC (N = 44 dyads). Mixed effects and generalized linear models compared severity of depression, anxiety, and a summed index of 16 other symptoms over weeks 1-13 and week 17 between randomized groups and among three dynamic treatment regimes (DTRs). Dyads received SMSH only for 12 weeks (DTR1); SMSH for 12 weeks with 8 weeks of TIPC added from week 1 (DTR2); and SMSH for 4 weeks followed by the combined SMSH + TIPC for 8 weeks if no response at 4 weeks (DTR3). RESULTS: Survivors randomized initially to SMSH alone had significantly lower anxiety over weeks 1-13 compared to those randomized to the combined SMSH + TIPC. In comparing DTRs, survivor's anxiety was significantly lower at week 13 for DTR1 compared to DTR2 with no other main effects for survivors or caregivers. Exploratory moderation analyses indicated a potential benefit of adding TIPC for caregivers of non-responders with elevated baseline symptoms. CONCLUSION: SMSH + TIPC did not result in better symptom outcomes at week 17 than SMSH alone. Lower intensity SMSH may improve depression and anxiety symptoms for most survivors and their caregivers.

Predictors of persistence of post-chemotherapy symptoms among survivors of solid tumor cancers.

CONTEXT: Late or residual symptoms diminish quality of life for many cancer survivors after completion of treatment. OBJECTIVES: Examine risk factors associated with persisting symptom burden after chemotherapy and the lack of symptom improvement over time. METHODS: Survivors who completed curative-intent chemotherapy within two years for solid tumors were enrolled into a symptom management trial. There were 375 survivors with two or more comorbid conditions or one comorbid condition and elevated depressive symptoms (pre-defined risk factors in the trial design) who received interventions and 71 survivors without these risk factors who did not receive interventions. For all survivors, symptoms were assessed at intake, 4, and 13 weeks and categorized as mild, moderate, or severe based on the interference with daily life. The probabilities of moderate or severe symptoms and symptom improvement were analyzed using generalized mixed-effects models in relation to comorbidity, depressive symptoms, age, sex, race/ethnicity, employment, time since chemotherapy completion, and physical function. Multiple symptoms were treated as nested within the survivor. RESULTS: Moderate or severe symptoms at baseline and the lack of improvement over time were associated with younger age and lower physical function over and above a greater number of comorbidities and elevated severity of depressive symptoms. CONCLUSION: Risk factors identified in this research (younger age, lower physical function, greater comorbidity, and higher depressive symptoms) can be used to allocate resources for post-treatment symptom management for cancer survivors in order to relieve symptoms that do not necessarily resolve with time.

Loneliness, Spirituality, and Health-Related Quality of Life in Hispanic English-Speaking Cancer Caregivers: A Qualitative Approach.

Hispanic caregivers experiencing higher caregiving burden than their non-Hispanic cohorts, due in part to contextual factors, such as barriers to accessing health care, challenging employment environments, low education and income, immigration issues, and minority stress. Spirituality may serve as a coping strategy for Hispanic caregivers that influences health-related quality of life (HRQoL), possibly by modifying loneliness associated with caregiving. We explored these concepts using semi-structured interviews (N = 10 Hispanic caregivers). Participants shared perceptions of loneliness, spirituality, and how these factors related to HRQoL. Five themes emerged: caregiver experience, coping strategies, loneliness, religion and spirituality to gain strength. Findings suggested that spirituality and religion improved HRQoL partially by reducing loneliness. Future programs to improve HRQoL in Hispanic English-speaking cancer caregivers should address spirituality.

Social isolation and social connectedness among young adult cancer survivors: A systematic review.

BACKGROUND: Social isolation and connectedness are social determinants of health that have demonstrated effects on cancer-related outcomes. These constructs have been systematically evaluated among pediatric and older adult cancer populations. In this review, the authors evaluated the prevalence, correlates, and psychosocial implications of social isolation and connectedness among young adult (YA) cancer survivors aged 18-39 years. METHODS: Peer-reviewed articles published in English before June 2021 were identified from database searches and included articles' reference lists according to PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. Included articles described studies that assessed social isolation and/or connectedness among YA cancer survivors. RESULTS: In total, 5094 unique records were identified; 4143 were excluded after title/abstract screening, and 907 were excluded after full-text review. Forty-four articles were included. Few studies used validated measures or directly assessed social isolation or connectedness. Social isolation was similarly prevalent among YAs and older cancer survivors and noncancer populations. Demographic, clinical, and behavioral risk and protective factors for social isolation were identified. Social isolation was related to worse psychological well-being, whereas social connectedness was often, but not always, related to better psychological well-being. CONCLUSIONS: This growing literature underscores the relevance of social isolation and connectedness as important health determinants among YA cancer survivors. The identified risk and protective factors can identify YAs who especially may benefit from screening for social isolation. Future studies are needed that directly, reliably, and validly evaluate social isolation and connectedness to inform the development of interventions to decrease isolation and increase connectedness.

Social Determinants of Health and Symptom Burden During Cancer Treatment.

BACKGROUND: Cancer survivors (defined as individuals from diagnosis to the end of life) in treatment experience multiple physical and psychological symptoms (e.g., fatigue, pain, depression, anxiety, disturbed sleep) that influence their well-being and treatment outcomes. Underrepresented cancer survivors may disproportionately experience greater symptom burden (number of symptoms, symptom severity, depression, anxiety). OBJECTIVES: The aim of this study was to examine the relationships of social determinants of health, including age, ethnicity, education, income and whether income meets the survivor's needs, neighborhood (rural vs. urban), access to healthcare (e.g., insurance), and social isolation, with symptom burden in cancer survivors. METHODS: This secondary analysis included baseline data from 400 cancer survivors of solid tumor cancers undergoing chemotherapy or targeted therapy who participated in a larger randomized trial of symptom management interventions. Symptom burden was measured by the Center for Epidemiological Studies-Depression scale for depression and Patient-Reported Outcomes Measurement Information System scores for anxiety and social isolation, summed severity index of 16 symptoms from the General Symptom Distress Scale, and the total number of symptoms. Self-reported comorbid conditions were measured using the Bayliss tool. General linear models were used to relate symptom measures (one at a time) to age, number of comorbid conditions, level of education, marital status, income meeting needs, and size of metropolitan neighborhood. Additional covariates included site of cancer, its treatment, and whether the cancer was metastatic. RESULTS: Non-Hispanic White survivors ( n = 191) were older and had more comorbid conditions, a higher proportion of metastatic cancers, and higher levels of education and income compared with Hispanic survivors ( n = 168) and non-Hispanic survivors of other races ( n = 41). Compared with the other two groups, Hispanic survivors had the lowest rate of health insurance availability, and non-Hispanic survivors of other races had the lowest social isolation. Age, number of comorbid conditions, and social isolation were significantly associated with number of symptoms, symptom severity, and depression. Age and social isolation were associated with anxiety. In addition, the symptom severity of non-Hispanic White survivors was lower than that of Hispanic survivors and non-Hispanic survivors of other races. DISCUSSION: These findings highlight the health disparities in symptom burden experienced among cancer survivors when considering their social determinants of health. Assessing these may help clinicians address health disparities in cancer care.

Social determinants of health, psychological distress, and caregiver burden among informal cancer caregivers of cancer survivors during treatment.

OBJECTIVE: This study compared three ethnic/racial groups of informal cancer caregivers on social determinants of health and tested social determinants of health as predictors of psychological distress and caregiver burden. METHODS: This study was a secondary analysis of baseline data of a sequential multiple assignment randomized trial (SMART) testing symptom management interventions with caregiver-survivor dyads. Caregivers completed baseline measures of social determinants of health (SDoH), functional limitations, psychological distress, and caregiver burden. Hispanic, non-Hispanic White, and non-Hispanic other races caregivers were compared on these variables. Multivariate tests of associations between SDoH and caregiver burden and psychological distress were conducted in structural equation modeling with caregiver burden and psychological distress as latent variables. RESULTS: Hispanic caregivers reported significantly higher caregiver burden, specifically for finances, family, and schedules. Caregiver burden was significantly predicted by having income barely or not meeting needs, being female, socially isolated, married, Hispanic, and having poor physical functioning. Significant predictors of caregivers' psychological distress: being female, being socially isolated, and having poor physical functioning. CONCLUSION: Hispanic caregivers experience significant challenges associated with caregiver burden, especially if they are female, socially isolated, and have poor physical functioning. Assessment of these SDoH is important in caregiver health to provide supportive care during caregiving. CLINICAL TRIAL REGISTRATION NUMBER: NCT03743415 www.clinicaltrials.gov.

Depression among Underserved Rural and Urban Caregivers of Latinas with Breast Cancer.

Among Latino/as, informal caregiving duties are often deemed a family responsibility. Understanding psychological outcomes tied to caregivers of Latina breast cancer survivors is important to identify the impacts of cancer. Secondary analysis of baseline data collected in a randomized clinical trial (RCT) from 230 Latina breast cancer survivor-caregiver dyads. Characteristics of caregivers residing in rural/underserved and urban areas were compared using t- or chi-square tests. General linear models were used to analyze depressive symptoms in relation to residence, survivor-caregiver relationship, acculturation, obligation, reciprocity, and comorbidities. Urban residence was significantly associated with higher levels of depression controlling for survivor-caregiver relationship acculturation, obligation, reciprocity, and comorbidities. Mother caregivers had significantly higher levels of depression than other caregivers. Depression among Latino/a caregiver's providing care to an adult child is an important consideration as Latino/as are less likely to seek out/have access to mental health services than other groups.

The Online Cancer Nutrition Misinformation: A framework of behavior change based on exposure to cancer nutrition misinformation.

BACKGROUND: Patients with cancer and caregivers increasingly use the internet to find health and lifestyle information, yet online recipes, diet, and nutrition content are unregulated and may be confusing or even misleading. We describe cancer-related nutrition and meal planning information from Pinterest. METHODS: In June 2020, we searched Pinterest using "cancer recipe" and "recipe for cancer" at 3 times daily for 2 weeks. Duplicates were removed for a final sample of n = 103 pins. Each pin was coded for 58 variables including descriptives, cancer claims (eg, treatment, prevention, and cure), and nutrition claims (eg, "turmeric cures cancer"). We summarized each variable to describe the content of cancer nutrition claims on Pinterest and examined associations between claim types and contextual factors, including the use of academic citations, disclaimers, and personal anecdotes. RESULTS: Pinners had on average 116,767 followers (range, 0-1.5 million). Almost half of content sites were for profit (48.5%) and 34% were selling a product. Health claims were common, with content that purported to prevent (41.8%), treat (27.2%), or cure (10.7%) cancer. Vague phrases such as "anti-cancer," "cancer-fighting," or "cancer-busting" were also used. The inclusion of validity indicators including academic citations, disclaimers, and personal anecdotes varied significantly by the types of claims made. Together, these analyses informed the development of a conceptual framework of cancer-related nutrition misinformation. CONCLUSIONS: There are clear financial incentives for the promotion of cancer nutrition information online. More research is needed to understand how exposure to nutrition information can influence patient/caregiver behavior and downstream clinical and psychosocial outcomes.

Exploring the relationship between loneliness, spirituality, and health-related quality of life in Hispanic cancer caregivers.

Caregivers of cancer patients find it challenging to perform their roles and to meet the demands of caregiving. Spirituality has been investigated as a potential coping strategy employed by caregivers, yet spirituality and related practices vary among cultural groups. In this study, we investigated the relationship between spirituality and health-related quality of life (HRQOL) and evaluated mediation effects of loneliness on this relationship. The sample was 234 lower socioeconomic status (SES) Hispanic caregivers of breast cancer survivors using existing data from the Support for Latinas with Breast Cancer and Their Intimate and Family Partners study, funded by the American Cancer Society (Badger, PI). A cross-sectional analysis was conducted at baseline, using self-reported spirituality, loneliness, and HRQOL data collected from 2012 to 2017. The exposures and outcomes were assessed using the Spiritual Well-Being Scale, the Social Isolation-Short Form 8a PROMIS Item Bank v2.0 scale, and the Global Health Scale PROMIS v.1.0/1.1 scale. Descriptive and mediation analyses using the Preacher and Hayes' approach were conducted to estimate the direct effect of spirituality on HRQOL and the indirect effect of spirituality through mediation of loneliness in relation to HRQOL. A positive association between spirituality and HRQOL was found, whereas loneliness was inversely associated with HRQOL (b = - .18, SE = .03, p < .0001). Age did not function as a moderator of the spirituality-HRQOL association in any of the models tested, but in the model testing mediation, loneliness was shown to mediate the association between spirituality and HRQOL (b = - .17, p < .0001). These results suggest that spirituality may be beneficial to HRQOL in caregivers of Hispanic breast cancer survivors, due in part to reduced loneliness among more spiritual caregivers.

Use of scheduled and unscheduled health services by cancer survivors and their caregivers.

PURPOSE: The purpose was to determine predictors of scheduled and unscheduled health services use by cancer survivors undergoing treatment and their informal caregivers. METHODS: English- or Spanish-speaking adult cancer survivors undergoing chemotherapy or targeted therapy for a solid tumor cancer identified a caregiver (N = 380 dyads). Health services use over 2 months was self-reported by survivors and caregivers. Logistic regression models were used to relate the likelihood of service use (hospitalizations, emergency department [ED] or urgent care visits, primary care, specialty care) to social determinants of health (age, sex, ethnicity, level of education, availability of health insurance), and number of comorbid conditions. Co-habitation with the other member of the dyad and other member's health services use were considered as additional explanatory variables. RESULTS: Number of comorbid conditions was predictive of the likelihood of scheduled health services use, both primary care and specialty care among caregivers, and primary care among survivors. Greater probability of specialty care use was associated with a higher level of education among survivors. Younger age and availability of health insurance were associated with greater unscheduled health services use (hospitalizations among survivors and urgent care or ED visits among caregivers). Unscheduled health services use of one member of the dyad was predictive of use by the other. CONCLUSIONS: These findings inform efforts to optimize health care use by encouraging greater use of scheduled and less use of unscheduled health services. These educational efforts need to be directed especially at younger survivors and caregivers.

Family caregivers of those with cancer: quality of life outcomes from a sequential multiple assignment randomized trial.

PURPOSE: To conduct a secondary analysis focused on health-related quality of life (HRQOL) among caregivers engaged in a 12-week complementary therapy sequential multiple assignment randomized trial (SMART) of reflexology and/or meditative practices (MP), to manage cancer patients' symptoms. METHODS: In this SMART, patient-caregiver dyads were initially randomized to 4 weeks of caregiver-delivered reflexology for the patient (N = 150), MP with the patient (N = 150), or control (N = 47). After 4 weeks, dyads with patients not improving on fatigue (non-responders, n = 69 to reflexology and n = 57 to MP) were re-randomized to continue the same therapy or add the other therapy for an additional 4 weeks. Week-12 caregiver HRQOL was measured using the Patient Reported Outcomes Measurement Information System (PROMIS) Profile-29 and the Caregiver Reaction Assessment Tool (CRAT) for caregiver burden; scores were analyzed using general linear models. RESULTS: In the comparison of 4 adaptive intervention sequences: reflexology for 8 weeks, reflexology for 4 weeks followed by MP for 4 weeks if no response to reflexology, MP for 8 weeks, and MP for 4 weeks followed by reflexology for 4 weeks if no response to MP, there were no differences in PROMIS-29 scores. However, CRAT domains of impact on schedule, family support, and finances worsened when adding reflexology after the first 4 weeks of MP. The CRAT domain of health worsened by adding either intervention compared to continuing the same one. CONCLUSIONS: Clinicians should be aware that caregiver engagement in more than one complementary therapy may increase caregiver burden in some domains but not affect other HRQOL domains.

Social support and healthcare utilization of caregivers of Latinas with breast cancer.

BACKGROUND: Family caregivers experience significant health consequences related to caregiving, including higher mortality rates. Latino caregivers may have additional challenges related to social determinants of health. Gender and social support are key factors to consider in the context of chronic illnesses and healthcare use in caregivers of Latinos diagnosed with cancer. PURPOSE: The purpose of this study was to examine the moderating effect of gender and social support on the relationship between chronic illnesses and healthcare utilization in caregivers of Latina breast cancer survivors. METHODS: This was a secondary analysis of family caregivers from an experimental study with breast cancer survivors and their designated family caregivers. Participants completed telephone surveys about demographics, presence of chronic illnesses, frequency of emergency department, urgent care, and hospital visits, social support, and acculturation. Data were analyzed for direct and moderated relationships. RESULTS: There was a significant relationship between number of chronic illnesses and healthcare utilization, informational support, and social isolation. Income and acculturation were not related to chronic illnesses or healthcare utilization. Gender did not moderate the relationship between chronic illnesses and healthcare utilization. Informational support was a marginal moderator of the relationship between chronic illnesses and healthcare utilization alone and with acculturation and income included as covariates. CONCLUSIONS: Clinicians should consider the influence of informational support and social isolation on chronic illnesses and healthcare use in caregivers of Latina breast cancer survivors, specifically, how these factors may influence navigation of the healthcare system.

Supportive health education reduces health care utilization and costs in Latinas with breast cancer and their caregivers.

PURPOSE: To compare costs and relative cost savings from reductions in unscheduled health services use for two 8-week psychosocial interventions (telephone interpersonal counseling [TIPC], supportive health education [SHE]) delivered by telephone to Latinas with breast cancer and their informal caregivers. Cost information is required before adopting supportive care interventions as part of routine care. There is limited information on costs of producing supportive care interventions or their impact on service use. METHODS: Latinas and their caregivers were randomized to either TIPC or SHE. At baseline and month 4, hospitalizations and urgent care and emergency department (ED) visits in the previous month were recorded. These were compared by trial arm for 181 survivors and 169 caregivers using logistic regression, adjusting for age and health services use at baseline. RESULTS: Total cost per 100 survivors was $28,695 for SHE and $27,399 for TIPC. Urgent care and ED visits were reduced for survivors in SHE versus TIPC (odds ratio (OR) = 0.31, 95% confidence interval (CI) [0.12, 0.88], p = .03). For hospitalizations, OR for SHE versus TIPC was 0.59, 95% CI [0.26, 1.37], p = .07. There were no differences between trial arms for caregiver health services use. Cost savings for SHE versus TIPC from reductions in health services use per 100 survivors ranged from $800 for urgent care to $17,000 for ED visits and $13,000 for hospitalizations. CONCLUSIONS: Based on this evidence, SHE can be a cost-saving supportive care solution that benefits not only survivors and caregivers, but also oncology practices reimbursed through episodes of care.

Reflexology and meditative practices for symptom management among people with cancer: Results from a sequential multiple assignment randomized trial.

Optimal sequencing of complementary therapies can help improve symptom management through nonpharmacological approaches. A 12-week sequential multiple assignment randomized trial comparing home-based reflexology and meditative practices on severity of fatigue and other symptoms was conducted among patients with cancer and their informal caregivers. Dyads were initially randomized to reflexology (N = 150), meditative practices (N = 150), or control (N = 47). If patient's fatigue did not improve (nonresponse) after 4 weeks of reflexology or meditative practices, the dyad was rerandomized to either add the other therapy or continue with the original therapy for weeks 5-8. Four decision rules (DRs) were compared: (1) Initiating reflexology, and if nonresponse on fatigue after 4 weeks, continue with reflexology for another 4 weeks, thus providing a higher dose; (2) Initiating reflexology, and if nonresponse on fatigue after 4 weeks, add meditative practices for the next 4 weeks; (3) Initiating meditative practices, and if nonresponse on fatigue after 4 weeks, continue meditative practices for another 4 weeks, thus providing a higher dose; and (4) Initiating meditative practices, and if nonresponse on fatigue after 4 weeks, add reflexology for the next 4 weeks. Symptoms were evaluated weekly using the M.D. Anderson Symptom Inventory (MDASI). Clinically, nurses can recommend either therapy since no differences were found among the 4 DRs, with the exception of lower severity for summed MDASI symptoms at week 8 for the use of reflexology only (DR-1) versus DR-2 (sequencing reflexology to meditative practices). Adding the other therapy for nonresponders after 4 weeks may not be warranted.

Interventions for Loneliness Among Adult Cancer Survivors: A Systematic Review and Meta-Analysis.

Problem identification: Loneliness is common after cancer, contributing to poor outcomes. Interventions to modify loneliness are needed. This systematic review describes the current literature regarding loneliness interventions in cancer survivors.Literature search: Databases including: Ovid/MEDLINE; The Cochrane Central Register of Controlled Trials (CENTRAL); Elsevier/Embase; Clarivate/Web of Science (Core Collection), EBSCO/PsycINFO, EBSCO/CINAHL were used to perform a systematic review of literature using PRISMA guidelines. Second, risk of bias, meta-analysis and a narrative synthesis approach was completed to synthesize findings from multiple studies.Data evaluation/synthesis: Six thousand five hundred three studies were initially evaluated; eight studies met inclusion criteria. Findings indicate a paucity of interventions, generally of lower quality. Interventions were feasible and acceptable; those interventions with cultural modifications were more likely to demonstrate effectiveness.Conclusions: There are limited interventions addressing loneliness in cancer survivors. Development and testing of culturally-relevant programs are warranted.Implications for psychosocial oncology: Current studies suggest the psychosocial symptom of loneliness is modifiable among adult cancer survivors. Few interventions have been tested and shown to be effectiveness in cancer survivors in the U.S. and none have been tailored for older adult survivors, by patient gender/sex and few for specific race/ethnic groups. Results from this systematic review: a narrative synthesis and meta-analysis can inform future interventions targeting loneliness in this growing, yet vulnerable, adult cancer survivor population.

The Evolution of Un Abrazo Para La Familia: Implications for Survivors of Cancer.

Un Abrazo Para La Familia™ (Abrazo) is a 3-h modular preventive intervention designed for low-income caregivers who are co-survivors of cancer. Here we (1) consider the benefit to survivors of cancer, that is, the care recipients who participate in Abrazo; (2) summarize the literature specific to research outreach to low-income, underserved populations when they are faced with cancer; and (3) describe current steps being taken in Southern Arizona to reach these populations via Abrazo. Specific to considering the benefit to care recipients, we analyzed care recipient data derived from three existing cohorts of Abrazo participants. Analyses of the combined cohorts of these data demonstrate that Abrazo is effective with care recipients given statistically significant higher cancer knowledge and self-efficacy scores, pre- vs. post-intervention. We can now report benefit to care recipients who participate in Abrazo. This allows us, with confidence, to expand research recruitment efforts to include care recipients as part of the Abrazo intervention in our efforts to serve low-income, underserved populations when faced with cancer.

Management of Distress in Patients with Cancer-Are We Doing the Right Thing?

BACKGROUND: Screening for distress and referral for the provision of psychosocial care is currently the preferred approach to the management of distress in patients with cancer. To date, this approach has shown a limited effect on the reduction of distress. Recent commentaries have argued that the implementation of distress screening should be improved. On the other hand, the underlying assumption that a referral for psychosocial care is required for distressed patients can be questioned. This has led to the development of an alternative approach, called emotional support and case finding. PURPOSE: In the context of finding innovative solutions to tomorrow's health challenges, we explore ways to optimize distress management in patients with cancer. METHODS AND RESULTS: We discuss three different approaches: (i) optimization of screening and referral, (ii) provision of emotional support and case finding, and (iii) a hybrid approach with multiple assessments, using mobile technology. CONCLUSIONS: We suggest continued research on the screening and referral approach, to broaden the evidence-base on improving emotional support and case finding, and to evaluate the utility of multiple assessments of distress with new interactive mobile tools. Lessons learned from these efforts can be applied to other disease areas, such as cardiovascular disease or diabetes.

Longitudinal dyadic interdependence in psychological distress among Latinas with breast cancer and their caregivers.

PURPOSE: Cancer diagnosis and treatment can generate substantial distress for both survivors and their family caregivers. The primary aim of this investigation is to test a model of dyadic interdependence in distress experienced by cancer survivors and their caregivers to determine if each influences the other. METHODS: To test this prediction, 209 Latinas with breast cancer and their family caregivers (dyads) were followed for 4 waves of assessment over the course of 6 months. Both psychological (depression, anxiety, perceived stress) and physical (number of symptoms, symptom distress) indicators of distress were assessed. Longitudinal analyses of dyadic data were performed in accordance with the actor-partner interdependence model. RESULTS: Findings indicated that psychological distress was interdependent between cancer survivors and their caregivers over the 6 months of observation. However, there was no such evidence of interdependence on indicators of physical distress. CONCLUSIONS: These findings are consistent with emotional contagion processes and point to the potential importance of caregiver well-being for the welfare of Latina breast cancer survivors.

Symptom Profiles of Latina Breast Cancer Survivors: A Latent Class Analysis.

BACKGROUND: Symptom research among Latinas with breast cancer is limited-especially as it relates to multiple co-occurring symptoms. OBJECTIVE: The aim of the study was to identify subgroups (latent classes) of Latinas who have distinct symptom profiles while receiving radiation, chemotherapy, and/or hormonal therapy for breast cancer. METHODS: This secondary analysis included intake data from three randomized trials of supportive care psychosocial interventions for Latinas treated for breast cancer (n = 290). Prevalence of 12 symptoms-measured using the General Symptom Distress Scale-was entered into the latent class analysis to identify classes of women with different symptom profiles. RESULTS: Most of the participants had Stage II or III disease, and 81% reported receiving chemotherapy. On average, women reported 4.2 (standard deviation [SD] = 3) symptoms with an overall symptom distress score of 6.4 (SD = 2.5) on a 1-10 scale, with 10 being most distressing. Latent class analysis resulted in three classes that were labeled based on symptoms with the highest prevalence. Class 1 (n = 192) was "Disrupted Sleep and Tired," Class 2 (n = 74) was "Tired," and Class 3 (n = 24) was "Pain, Disrupted Sleep, and Tired." Depression, anxiety, and difficulty concentrating had moderate prevalence in each of the three classes. DISCUSSION: Beyond the core six symptoms (depression, anxiety, fatigue, pain, disrupted sleep, difficulty concentration), the classes differed in the prevalence of other burdensome symptoms (e.g., nausea, vomiting, constipation), which provide implications for treatment. Thus, it is important to assess for the full range of symptoms so that supportive care interventions can be tailored for the distinct symptom profiles of Latinas with breast cancer.

Using the RE-AIM framework for dissemination and implementation of psychosocial distress screening.

OBJECTIVE: To evaluate the RE-AIM framework's effect on retention of participants and implementation outcomes of a 5-year cancer research education programme on psychosocial distress screening in cancer centres across the United States. METHODS: A one-group pre-/post-test design was used to evaluate the programme on participant retention and implementation outcomes at 6, 12 and 24 months after enrolling in the programme (baseline) and analysed using descriptive statistics. RESULTS: Seventy-two cancer centres participated in four cohorts. Participant retention was 100%. At baseline and 24 months, respectively, 52 (72%) and 64 (88%) of the cancer centres had formulated a psychosocial distress screening policy; 51 (71%) and 70 (98%) had started screening in more than one clinic/population; 15 (21%) and 45 (63%) had started auditing health records for documentation of screening. Each outcome rate improved at the cancer-centre level over the 24 months. CONCLUSION: RE-AIM can be used as a framework for cancer research education programmes. Future research is needed on the use of a randomised adaptive design to test the optimal support for implementation of quality care standards according to cancer centres' needs.
