Light therapy as a treatment of cancer-related fatigue in (non-)Hodgkin lymphoma survivors (SPARKLE trial): study protocol of a multicenter randomized controlled trial.

BACKGROUND: Cancer related fatigue (CRF) is one of the most prevalent and distressing long-term complaints reported by (non-) Hodgkin survivors. To date there has been no standard treatment for CRF in this population. A novel and promising approach to treat CRF is exposure to bright white light therapy. Yet, large scale randomized controlled trials testing its efficacy in these patients and research on potential mechanisms is lacking. The objective of the current study is to investigate the efficacy of light therapy as a treatment for CRF and to explore potential mechanisms. METHODS/DESIGN: In a multicenter, randomized controlled trial we are evaluating the efficacy of two intensities of light therapy in reducing CRF complaints and restrictions caused by CRF in survivors of Hodgkin lymphoma or diffuse large B-cell lymphoma. Secondary outcomes include sleep quality, depression, anxiety, quality of life, cognitive complaints, cancer worries, fatigue catastrophizing, self-efficacy to handle fatigue, biological circadian rhythms of melatonin, cortisol and activity, and biomarkers of inflammation. We will recruit 128 survivors, with fatigue complaints, from academic and general hospitals. Survivors are randomized to either an intervention (exposure to bright white light) or a comparison group (exposure to dim white light). The longitudinal design includes four measurement points at baseline (T0), post-intervention at 3.5 weeks (T1), 3 months post-intervention (T2) and 9 months post-intervention (T3). Each measurement point includes self-reported questionnaires and actigraphy (10 days). T0 and T1 measurements also include collection of blood and saliva samples. DISCUSSION: Light therapy has the potential to be an effective treatment for CRF in cancer survivors. This study will provide insights on its efficacy and potential mechanisms. If proven to be effective, light therapy will provide an easy to deliver, low-cost and low-burden intervention, introducing a new era in the treatment of CRF. TRIAL REGISTRATION: The study is registered at ClinicalTrials.gov on August 8th 2017( NCT03242902 ).

Dyadic psychosocial intervention for advanced lung cancer patients and their family caregivers: results of a randomized pilot trial.

BACKGROUND: Advanced lung cancer (LC) patients and their families have reported low self-efficacy for self-care/caregiving and high rates of distress, yet few programs exist to address their supportive care needs during treatment. This pilot study examined the feasibility, acceptability, and preliminary efficacy of a 6-session, telephone-based dyadic psychosocial intervention that was developed for advanced LC patients and their caregivers. The program was grounded in self-determination theory (SDT), which emphasizes the importance of competence (self-efficacy), autonomy (sense of choice/volition), and relatedness (sense of belonging/connection) for psychological functioning. The primary outcomes were patient and caregiver psychological functioning (depression/anxiety) and caregiver burden. The secondary outcomes were the SDT constructs of competence, autonomy, and relatedness. METHODS: Thirty-nine advanced LC patients who were within 1 month of treatment initiation (baseline) and their caregivers (51% spouses/partners) completed surveys and were randomized to the intervention or usual medical care. Eight weeks after baseline, they completed follow-up surveys. RESULTS: Solid recruitment (60%) and low attrition rates demonstrated feasibility. Strong program evaluations (mean, 8.6/10) and homework completion rates (88%) supported acceptability. Participants receiving the intervention evidenced significant improvements (P < .0001) in depression, anxiety, and caregiver burden in comparison with usual medical care. Large effect sizes (d ≥ 1.2) favoring the intervention were also found for patient and caregiver competence and relatedness and for caregiver autonomous motivation for providing care. CONCLUSION: These findings support intervention feasibility, acceptability, and preliminary efficacy. By empowering families with the skills to coordinate care and meet the challenges of LC together, this intervention holds great promise for improving palliative/supportive care services in cancer.

Colonoscopy-specific fears in African Americans and Hispanics.

Although fears of colonoscopy may deter African Americans and Hispanics from having a screening colonoscopy, little is known about these fears. This study examined the proportion of African Americans and Hispanics who experience colonoscopy-specific fears and identified factors associated with these fears. Data were collected at an academic hospital in New York City between 2008-2010. African Americans (N = 383) and Hispanics (N = 407) who received a recommendation for a screening colonoscopy completed a questionnaire that assessed: colonoscopy-specific fears, demographics, and psychological variables. Presence of colonoscopy-specific fears was endorsed by 79.5% of participants. Being female (p < 0.001), speaking English (p < 0.001), having greater perceived risk of colorectal cancer (CRC) (p < 0.01), greater worry about risk of CRC (p < 0.01), greater fear of CRC (p < 0.001) and lower levels of self-efficacy of having a colonoscopy (p < 0.01) were associated with greater colonoscopy-specific fears. Results can inform interventions designed to assuage fears in African Americans and Hispanics.

The effectiveness of caregiver social support is associated with cancer survivors' memories of stem cell transplantation: A linguistic analysis of survivor narratives.

OBJECTIVE: People who undergo hematopoietic stem cell transplantation are highly dependent on their caregiver during their lengthy treatment and recovery. The effectiveness of their caregiver's social support can profoundly affect their day-to-day treatment experiences and, in turn, how they recall those experiences and are affected by them long after the treatment ends. METHOD: Our participants were 182 men and women who had undergone a transplant within the previous 9 months to 3 years. They completed baseline measures (including a measure of caregiver social support effectiveness) and then completed three writing assignments describing their transplant experiences. Linguistic analyses were conducted to investigate their use of words indicating negative emotions, cognitive processing (insight and causation), and practical problems with money and insurance. Theory-based hypotheses predicted associations between specific functional types of caregiver support (emotional, informational, and instrumental) and these word categories. RESULTS: As hypothesized, the effectiveness of different functional types of support from a caregiver were uniquely associated with theoretically relevant categories of word use. Structural equation models indicated that more effective caregiver emotional support predicted lower use of negative emotion words; more effective caregiver informational support predicted lower use of causation words; and more effective caregiver instrumental support predicted lower use of words related to money and insurance. SIGNIFICANCE OF RESULTS: Our findings provide insights to guide research on the mechanisms through which caregiver support influences patient outcomes after stem cell transplantation. For instance, research suggests that these kinds of effects could have implications for survivors' current self-concept, psychosocial functioning, and meaning-making.

Objective and subjective socioeconomic status and health symptoms in patients following hematopoietic stem cell transplantation.

OBJECTIVE: Recent research indicates that subjective socioeconomic status (SES) ­ the perception of one's own SES compared with other people ­ is an important predictor of cancer-related health outcomes. Subjective SES may function as a psychosocial mechanism by which objective SES affects health, well-being, and, more broadly, quality of life among cancer survivors. This study tested whether the association between objective SES and indicators of quality of life was mediated by subjective SES in a sample of cancer survivors who had undergone hematopoietic stem cell transplantation. METHODS: Hematopoietic stem cell transplantation survivors (N=268) completed measures of objective and subjective SES, along with four measures related to quality of life (depressive symptoms, health-related quality of life, symptoms of generalized distress, and posttraumatic stress disorder symptoms). RESULTS: Higher objective SES was associated with greater quality of life across all four measures. Subjective SES mediated the relationship between objective SES and depressive symptoms (total indirect effect b=-0.09, 95% confidence interval [CI] [-0.15, -0.05]), generalized distress (total indirect effect b=-0.08, 95% CI [-0.13, -0.04]), health-related quality of life (total indirect effect b=0.10, 95% CI [0.06, 0.17]), and posttraumatic stress disorder (total indirect effect b=-0.08, 95% CI [-0.14, -0.04]). CONCLUSIONS: Findings extend work on subjective SES to cancer and suggest that SES gradients in patient outcomes after cancer may reflect not only material resources but also psychosocial factors related to rank within social hierarchies. Further research may provide insights useful for reducing disparities in this population

Cross-sectional study of patient-reported neurobehavioral problems following hematopoietic stem cell transplant and health-related quality of life.

OBJECTIVE: Although hematopoietic stem cell transplant (HSCT) patients may experience neurocognitive impairment, experiences of neurobehavioral problems (including apathy and disinhibition) are understudied. These experiences reflect behavioral signs and symptoms of neurological dysfunction that can potentially reduce health-related quality of life (HRQOL). Understanding them is important because they may be confused with other diagnoses, including depression, potentially leading to inappropriate treatments. The objectives of this preliminary cross-sectional study were to describe HSCT patients' neurobehavioral functioning pre-HSCT and post-HSCT and to examine relations with HRQOL. METHODS: Patients (n = 42) 9 months to 3 years post-HSCT completed measures of neurobehavioral functioning to report apathy and disinhibition pre-HSCT (retrospectively) and post-HSCT (currently). Paired t-tests and McNemar tests were used to explore differences in the incidence of patient-reported neurobehavioral problems within and across time points. Regression analyses were conducted to examine relations between neurobehavioral functioning and physical and mental HRQOL. RESULTS: Elevated levels of apathy were reported by many patients post-HSCT (36%) and increased significantly from pre-HSCT to post-HSCT (p = 0.001). Hierarchical regression analysis indicated that higher levels of apathy were associated with reduced mental HRQOL (p < 0.05) even after controlling for depressed mood and fatigue. CONCLUSIONS: Findings from this preliminary study highlight the importance of investigating neurobehavioral problems, particularly apathy, in HSCT patients. Because apathy is often confused with other diagnoses and may worsen HRQOL, understanding the nature of these symptoms has implications for interventions. Further research is needed in this important area.

Associations among pain, pain attitudes, and pain behaviors in patients with metastatic breast cancer.

Metastatic breast cancer (MBC) patients often experience pain which can trigger pain behaviors, such as distorted ambulation. Psychological variables, such as individuals' attitudes toward pain, play a role in pain intervention. In this study, we used the cognitive-behavioral model of pain to examine the influence of patients' attitudes toward pain (as measured by the survey of pain attitudes or SOPA) on their pain behaviors (as measured by the pain behaviors checklist). Two hundred-one MBC patients completed surveys at treatment initiation and again 3 and 6 months later. Linear Mixed Model with repeated measures analyses showed that SOPA-solicitude, SOPA-emotions, SOPA-cure, SOPA-disability, and SOPA-medication pain attitudes were consistently significantly associated with pain behaviors at each assessment time point. Additionally, the belief that a medical cure for pain exists buffered the positive association between pain severity and pain behaviors. Our findings support and extend the cognitive-behavioral model of pain and suggest that it may be useful to target pain attitudes in pain management interventions for MBC patients.

Healing stories: narrative characteristics in cancer survivorship narratives and psychological health among hematopoietic stem cell transplant survivors.

OBJECTIVES: Survivors of hematopoietic stem cell transplant (HSCT) have experienced a life threatening and potentially traumatic illness and treatment that make them vulnerable to long lasting negative psychological outcomes, including anxiety and depression. Nevertheless, studies show that overcoming cancer and its treatment can present an opportunity for personal growth and psychological health (reduced symptoms of anxiety and depression and high levels of emotional well-being) through resilience. However, research has not yet clarified what differentiates HSCT survivors who experience psychological growth from those who do not. By analyzing recovery narratives, we examined whether HSCT survivors' interpretation of their experiences helps explain differences in their post-treatment psychological health. METHODS: Guided by narrative psychology theory, we analyzed the narratives of 23 HSCT survivors writing about their experience of cancer treatment. Psychological health was measured by: (1) emotional well-being subscale part of the Functional Assessment of Cancer Therapy Bone Marrow Transplant (FACT-BMT), (2) depression, and (3) anxiety subscales of the Brief Symptom Inventory. RESULTS: Findings revealed a positive relation between psychological health and a greater number of redemption episodes (going from an emotionally negative life event to an emotionally positive one) as well as fewer negative emotional expressions. SIGNIFICANCE OF THE RESULTS: Theoretical and practical implications of these findings are discussed, showing how narratives can inform interventions to assist cancer survivors with their psychological recovery.

Posttraumatic growth, social support, and social constraint in hematopoietic stem cell transplant survivors.

OBJECTIVE: The relation between posttraumatic growth (PTG) and aspects of the social context, such as social support and social constraint, continues to be unclear in cancer survivors. Social cognitive processing theory is a useful framework for examining the effect of the social context on PTG. In theory, support interactions may either facilitate or hinder cognitive processing and thus lead to different PTG outcomes. The current study tested the hypothesis that emotional support and instrumental support would each explain a unique amount of the variance in PTG in distressed hematopoietic stem cell transplant (HSCT) survivors. Additionally, it was predicted that social constraint on cancer-related disclosure would be negatively associated with PTG. METHODS: Forty-nine distressed HSCT survivors with a spouse or partner completed the posttraumatic growth inventory and measures of social support received from their spouse/partner and social constraint from people close to them as part of a larger clinical trial. RESULTS: Both emotional and instrumental social support were positively correlated with PTG, and social constraint on disclosure was not associated with PTG. Contrary to hypotheses, instrumental support was the only unique social contextual predictor of PTG. CONCLUSIONS: The results of this study highlight the importance of examining the effects of subtypes of social support on PTG separately. Findings are discussed in the context of the cognitive (i.e., processing of the traumatic event) versus non-cognitive (i.e., buffering stress) pathways between the social context and PTG. Future research directions are presented.

Economic survivorship stress is associated with poor health-related quality of life among distressed survivors of hematopoietic stem cell transplantation.

BACKGROUND: Hematopoietic stem cell transplantation is a demanding cancer treatment associated with enduring physical and psychological complications. Survivors' well-being may be further compromised by exposure to chronic stressors common to this population, including difficulties arising from costly medical care, changes in employment status, and health insurance coverage. Thus, we hypothesized that financial, employment, and insurance stressors (collectively referred to as economic survivorship stressors) would be associated with poorer health-related quality of life (HRQOL) among hematopoietic stem cell transplantation survivors. METHODS: Survivors (n = 181; M = 640 days post-transplant) completed the measures of study variables through mailed questionnaires and telephone interviews. Hierarchical regression analyses were conducted to test the hypothesized associations between economic survivorship stressors and HRQOL, and to examine whether social and situational factors interact with survivors' stress perceptions to predict HRQOL. RESULTS: Greater financial and employment stress were associated with poorer functioning across multiple HRQOL domains, even after controlling for the effects of possible confounding sociodemographic and medical variables. Insurance stress was not associated with HRQOL. Some associations were moderated by situational factors including timing of the current financial crisis and portion of the transplant paid for by health insurance. CONCLUSIONS: Hematopoietic stem cell transplantation survivors can face serious economic challenges during recovery. Results suggest the value of viewing these challenges as chronic stressors capable of reducing survivors' mental and physical well-being. Identifying resources and skills that help survivors cope with these demands is an important goal for clinicians and researchers.

Self-efficacy beliefs mediate the relationship between subjective cognitive functioning and physical and mental well-being after hematopoietic stem cell transplant.

OBJECTIVE: Cognitive problems are commonly reported by hematopoietic stem cell transplant (HSCT) survivors and are associated with poorer physical and mental well-being. It was hypothesized that adverse effects of subjective cognitive impairment occur because cognitive difficulties reduce survivors' confidence that they can manage HSCT-related symptoms-that is, self-efficacy for symptom management. METHODS: Hematopoietic stem cell transplant survivors (n = 245), 9 months to 3 years post-HSCT, completed measures of subjective cognitive functioning, self-efficacy for symptom management, and clinically important outcomes: depressed mood, anxiety, and quality of life. Mediation analyses using bootstrapping were conducted to investigate whether effects of subjective cognitive impairment on these outcomes were mediated by self-efficacy for cognitive, emotional (SE-Emotional), social (SE-Social), and physical (SE-Physical) symptom management. RESULTS: Self-efficacy mediated relations between subjective cognitive impairment and depressed mood (total indirect effect = -0.0064 and 95% CI -0.0097 to -0.0036), anxiety (total indirect effect = -0.0045, CI -0.0072 to -0.0021), and quality of life (total indirect effect = 0.0952, CI 0.0901 to 0.2642). SE-Emotional was a unique mediator when the outcome was depressed mood and anxiety. SE-Social, SE-Physical, and SE-Emotional were specific mediators when outcome was quality of life. CONCLUSIONS: Findings support the conclusion that subjective cognitive impairment reduces HSCT survivors' confidence in their ability to manage common post-HSCT symptoms, with implications for physical and mental well-being. Interventions that help enhance survivors' self-efficacy, particularly self-efficacy for the management of emotional symptoms, are likely to benefit HSCT survivors who report subjective cognitive impairment.

Examining the Efficacy of Bright Light Therapy on Cognitive Function in Hematopoietic Stem Cell Transplant Survivors.

Patients who have undergone hematopoietic stem cell transplant (HSCT) may experience cognitive impairment that can persist after treatment. Several studies have shown that bright light therapy may improve cognition, potentially due to its effects on the circadian system via brain regions that respond preferentially to light. In this double-blind randomized controlled trial, the efficacy of bright light therapy on cognition was examined in HSCT survivors. Forty-seven HSCT survivors at an urban hospital in the United States were screened for mild cognitive impairment, randomized to either bright white light (BWL) or comparison dim red light (DRL) conditions using a block randomization approach, and instructed to use their assigned light box every morning upon awakening for 30 min for 4 weeks. Assessments occurred at baseline, the end of the second week of the intervention, the end of the intervention, and at follow-up (8 weeks later). The primary outcome was objective cognitive function as measured by a global composite score on neuropsychological tests. Secondary outcomes included cognitive performance in individual domains, self-reported cognitive function, fatigue, sleep and sleep quality, and circadian rhythm robustness. Repeated-measures linear mixed models for both objective and self-reported cognitive function indicated significant main effects for time (ps < 0.05) suggesting significant improvements in both conditions over time. Time by light condition interaction effects were not significant. Models focused on secondary outcomes yielded no significant effects. Both BWL and DRL groups demonstrated significant improvements in objective cognitive and self-reported cognitive function over time, but there was no hypothesized effect of BWL over DRL nor associations with circadian rhythm robustness. Therapeutic effects of both light conditions, practice effects, and/or placebo effects may account for the findings.Trial registration: ClinicalTrials.gov Identifier: NCT02677987 (9 February 2016).

Quality of life concerns and depression among hematopoietic stem cell transplant survivors.

PURPOSE: This study examined quality of life, transplant-related concerns, and depressive symptoms and their demographic and medical correlates at 1 to 3 years following hematopoietic stem cell transplantation (HSCT). METHODS: HSCT survivors (N=406) completed telephone-administered questionnaires that assessed demographic variables, functional status, quality of life, transplant-related concerns, and depressive symptoms. RESULTS: The most prevalent concerns among HSCT survivors included physical symptoms (e.g., fatigue and pain), maintaining current health status and employment, changes in appearance, and lack of sexual interest and satisfaction. In addition, almost one-third (32%) of survivors age 40 years and younger reported concern about their ability to have children. Unemployed survivors and those with lower incomes and worse functional status were more likely to experience poorer quality of life in multiple domains. Fifteen percent of the sample reported moderate to severe depressive symptoms, and these symptoms were higher among allogeneic transplant recipients and those with lower functional status. CONCLUSIONS: Results suggest that interventions are needed to address physical symptoms, coping with an uncertain future, infertility, and sexual issues during the early phase of HSCT survivorship.

Training experiences of lay and professional patient navigators for colorectal cancer screening.

Patient navigation (PN) is increasingly used in cancer care, but little is known about the identification and training of patient navigators. PN may be implemented by professional health care providers, paraprofessionals, or lay health workers and, therefore, presents an opportunity to compare professional and lay interventionist experiences. The goal of the current report is to compare the training experiences of four professional (Pro) and five lay (LHW) patient navigators enlisted to increase colonoscopy adherence among African American primary care patients. The results of early assessments showed that LHWs' intervention-related knowledge was significantly lower than that of Pros. However, there were no significant differences in knowledge scores between LHWs and Pros for most subsets of knowledge items in later assessments. Furthermore, there were no significant differences in LHWs' and Pros' reported self-efficacy and satisfaction with training. Findings support the use of diverse strategies to train and prepare LHWs as patient navigators.

It Takes a Team to Make It Through: The Role of Social Support for Survival and Self-Care After Allogeneic Hematopoietic Stem Cell Transplant.

BACKGROUND: Social support plays an important role for health outcomes. Support for those living with chronic conditions may be particularly important for their health, and even for their survival. The role of support for the survival of cancer patients after receiving an allogeneic hematopoietic cell transplant (alloHCT) is understudied. To better understand the link between survival and support, as well as different sources and functions of support, we conducted two studies in alloHCT patients. First, we examined whether social support is related to survival (Study 1). Second, we examined who provides which support and which specific support-related functions and tasks are fulfilled by lay caregivers and healthcare professionals (Study 2). METHODS: In Study 1, we conducted a retrospective chart review of alloHCT patients (N = 173, 42.8% female, age: M = 49.88) and registered availability of a dedicated lay caregiver and survival. In Study 2, we prospectively followed patients after alloHCT (N = 28, 46.4% female, age: M = 53.97, 46.4% ethnic minority) from the same hospital, partly overlapping from Study 1, who shared their experiences of support from lay caregivers and healthcare providers in semi-structured in-depth interviews 3 to 6 months after their first hospital discharge. RESULTS: Patients with a dedicated caregiver had a higher probability of surviving to 100 days (86.7%) than patients without a caregiver (69.6%), OR = 2.84, p = 0.042. Study 2 demonstrated the importance of post-transplant support due to patients' emotional needs and complex self-care regimen. The role of lay caregivers extended to many areas of patients' daily lives, including support for attending doctor's appointments, managing medications and financial tasks, physical distancing, and maintaining strict dietary requirements. Healthcare providers mainly fulfilled medical needs and provided informational support, while lay caregivers were the main source of emotional and practical support. CONCLUSION: The findings highlight the importance of studying support from lay caregivers as well as healthcare providers, to better understand how they work together to support patients' adherence to recommended self-care and survival.

Light Therapy for Cancer-Related Fatigue in (Non-)Hodgkin Lymphoma Survivors: Results of a Randomized Controlled Trial.

PURPOSE: To evaluate the short- and long-term effects of light therapy on fatigue (primary outcome) and sleep quality, depression, anxiety, quality of life, and circadian rhythms (secondary outcomes) in survivors of (non-)Hodgkin lymphoma presenting with chronic cancer-related fatigue. METHODS: We randomly assigned 166 survivors (mean survival 13 years) to a bright white light intervention (BWL) or dim white light comparison (DWL) group. Measurements were completed at baseline (T0), post-intervention (T1), at three (T2), and nine (T3) months follow-up. A mixed-effect modeling approach was used to compare linear and non-linear effects of time between groups. RESULTS: There were no significant differences between BWL and DWL in the reduction in fatigue over time. Both BWL and DWL significantly (p < 0.001) improved fatigue levels during the intervention followed by a slight reduction in this effect during follow-up (EST0-T1 = -0.71; EST1-T3 = 0.15). Similar results were found for depression, sleep quality, and some aspects of quality of life. Light therapy had no effect on circadian rhythms. CONCLUSIONS: BWL was not superior in reducing fatigue compared to DWL in HL and DLBCL survivors. Remarkably, the total sample showed clinically relevant and persistent improvements on fatigue not commonly seen in longitudinal observational studies in these survivors.

Physical, psychological, and social sequelae following hematopoietic stem cell transplantation: a review of the literature.

OBJECTIVE: This article reviews recent literature on adults' quality of life following hematopoietic stem cell transplantation (HSCT). METHODS: We identified 22 prospective reports with at least 20 participants at baseline through a search of databases (Medline and PsycInfo) and handsearching of articles published from 2002 to October 2007. If longitudinal data were not available or were scarce for a particular topic or time point, cross-sectional studies were reviewed. RESULTS: Although physical, psychological, and social aspects of quality of life tend to improve during the years following transplantation, a significant proportion of HSCT survivors experience persistent anxiety and depressive symptoms, fatigue, sexual dysfunction, and fertility concerns. Despite ongoing treatment side effects, the majority of HSCT survivors resume their work, school, or household activities. CONCLUSION: We conclude that theory-driven research with larger samples is needed to identify subgroups of HSCT survivors with adjustment difficulties. Such research would examine survivors' evolving standards and definitions of quality of life to improve the accuracy and meaningfulness of assessment and incorporate biological, psychological, and contextual factors that may contribute to positive adjustment.

Acculturation and familiarity with, attitudes towards and beliefs about genetic testing for cancer risk within Latinas in East Harlem, New York City.

Recent research underscores the need for increasing use of genetic testing for cancer risk in Latinos. This study examined the influence of acculturation on attitudes, beliefs about and familiarity with genetic testing for cancer risk in a community-based sample of Latinas in East Harlem, New York City (N = 103). Multivariate linear regression models analyzed the relationship of acculturation to: (1) familiarity (2) perceived benefits (3) perceived barriers and (4) concerns about abuses of genetic testing for cancer risk. Controlling for sociodemographic factors, results revealed that with increasing acculturation Latinas were more familiar with genetic testing (beta = 1.62, SE = 0.72, p = 0.03), more likely to cite perceived benefits (beta = 1.67, SE = 0.79, p = 0.04), and less likely to report perceived barriers related to genetic testing (beta = -2.76, SE = 1.64, p = 0.10). Study results may help inform the development of culturally-appropriate health education outreach materials and programs targeted to increase awareness, knowledge and understanding about genetic testing for cancer risk within Latinas.

Social support from family and friends as a buffer of low spousal support among mothers of critically ill children: A multilevel modeling approach.

OBJECTIVE: To investigate whether social support from family and friends (family/friend support) attenuated ("buffered") adverse effects of having low spouse support (spousal support) among mothers of children undergoing hematopoietic stem cell transplantation (HSCT). DESIGN: One hundred sixty-three married mothers who were their child's primary caregiver during treatment completed assessments during the child's hospitalization for HSCT and 3-, 6-, and 12-months post-HSCT. MEASURES: Family/friend support and spousal support were assessed during hospitalization. Maternal physical and mental health-related functioning (the main outcome measures) were assessed at all timepoints. RESULTS: Multilevel modeling was used to analyze trajectories of maternal functioning. Findings indicated that mothers with low spousal support and low family/friend support demonstrated the worst functioning across all timepoints. Mothers with low spousal support and high family/friend support demonstrated significantly better functioning, supporting the hypothesized buffering effect. Their functioning compared to the functioning of mothers with high spousal support. Moreover, mothers with high family/friend support demonstrated trajectories of physical health-related functioning that were more stable than the trajectories of mothers with low family/friend support. CONCLUSION: These findings have clinical implications in addition to advancing knowledge of social support processes among couples coping with the shared stressor of a child's life-threatening illness and treatment.
