Age Differences in Core Symptoms and Symptom Relationships in Patients With Irritable Bowel Syndrome: A Network Analysis.

INTRODUCTION: Irritable bowel syndrome (IBS) is a common disorder of gut-brain interaction, characterized by symptoms of abdominal pain and changes in bowel habits. It often co-occurs with extraintestinal somatic and psychological symptoms. However, the nature of the interrelationships among these symptoms is unclear. Although previous studies have noted age differences in IBS prevalence and specific symptom severity, it remains unknown whether specific symptoms and symptom relationships may differ by age. METHODS: Symptom data were collected in 355 adults with IBS (mean age 41.4 years, 86.2% female). Network analysis was used to examine the interrelationships among 28 symptoms and to identify the core symptoms driving the symptom structure between young (≤45 years) vs older (>45 years) adults with IBS. We evaluated 3 network properties between the 2 age groups: network structure, edge (connection) strength, and global strength. RESULTS: In both age groups, fatigue was the top core symptom. Anxiety was a second core symptom in the younger age group, but not the older age group. Intestinal gas and/or bloating symptoms also exerted considerable influences in both age groups. The overall symptom structure and connectivity were found to be similar regardless of age. DISCUSSION: Network analysis suggests fatigue is a critical target for symptom management in adults with IBS, regardless of age. Comorbid anxiety is likely an important treatment focus for young adults with IBS. Rome V criteria update could consider the importance of intestinal gas and bloating symptoms. Additional replication with larger diverse IBS cohorts is warranted to verify our results.

Cancer disparities in the context of rurality: risk factors and screening across various U.S. rural classification codes.

PURPOSE: Prior cancer research is limited by inconsistencies in defining rurality. The purpose of this study was to describe the prevalence of cancer risk factors and cancer screening behaviors across various county-based rural classification codes, including measures reflecting a continuum, to inform our understanding of cancer disparities according to the extent of rurality. METHODS: Using an ecological cross-sectional design, we examined differences in cancer risk factors and cancer screening behaviors from the Behavioral Risk Factor Surveillance System and National Health Interview Survey (2008-2013) across rural counties and between rural and urban counties using four rural-urban classification codes for counties and county-equivalents in 2013: U.S. Office of Management and Budget, National Center for Health Statistics, USDA Economic Research Service's rural-urban continuum codes, and Urban Influence Codes. RESULTS: Although a rural-to-urban gradient was not consistently evident across all classification codes, the prevalence of smoking, obesity, physical inactivity, and binge alcohol use increased (all ptrend < 0.03), while colorectal, cervical and breast cancer screening decreased (all ptrend < 0.001) with increasing rurality. Differences in the prevalence of risk factors and screening behaviors across rural areas were greater than differences between rural and urban counties for obesity (2.4% vs. 1.5%), physical activity (2.9% vs. 2.5%), binge alcohol use (3.4% vs. 0.4%), cervical cancer screening (6.8% vs. 4.0%), and colorectal cancer screening (4.4% vs. 3.8%). CONCLUSIONS: Rural cancer disparities persist across multiple rural-urban classification codes, with marked variation in cancer risk factors and screening evident within rural regions. Focusing only on a rural-urban dichotomy may not sufficiently capture subpopulations of rural residents at greater risk for cancer and cancer-related mortality.

Psychological Impacts and Ways of Coping Reported by Spousal Caregivers of Hematopoietic Cell Transplant Recipients: A Qualitative Analysis.

Allogeneic hematopoietic cell transplantation (HCT) is a demanding treatment with well-established medical and psychosocial sequelae. Impacts on significant others are tremendous. Using an unfiltered qualitative approach, we asked spouses (n = 15) of HCT recipients to talk about their thoughts and feelings regarding the transplantation and their role as caregiver. Recordings were transcribed and independently coded to identify recurrent patterns. Caregivers mentioned both negative and positive psychological impacts of HCT, but the number of negative impacts was greater: 164 versus 34 instances. The most frequently mentioned negative psychological impacts were anxiety/worry (30 instances), fear (20 instances), feeling overloaded/overwhelmed (19 instances), and uncertainty (17 instances). Other emergent categories were roles/responsibilities (49 instances) such as parenting, work, and treatment-related tasks, and coping strategies (55 instances). The latter included both adaptive and maladaptive strategies (75% and 25%, respectively). Despite the preponderance of negatively toned thoughts and feelings, signs of adjustment emerged, with mentions of positive psychological states, such as optimism and gratitude, and adaptive coping strategies, such as active coping, use of emotional support, and self-care. Interventions intended to facilitate adaptation to the HCT experience should involve strategies to help caregivers manage symptoms of distress and promote adaptive coping.

Driving Distance and Patient-Reported Outcomes in Hematopoietic Cell Transplantation Survivors.

Long driving distances to transplantation centers may impede access to care for hematopoietic cell transplantation (HCT) survivors. As a secondary analysis from the multicenter INSPIRE study (NCT01602211), we examined baseline data from relapse-free HCT adult survivors (2 to 10 years after allogeneic or autologous HCT) to investigate the association between driving distances and patient-reported outcome (PRO) measures of distress and physical function. We analyzed predictors of elevated distress and impaired physical function using logistic regression models that operationalized driving distance first as a continuous variable and separately as a dichotomous variable (<100 versus 100+ miles). Of 1136 patients available for analysis from 6 US centers, median driving distance was 82 miles and 44% resided 100+ miles away from their HCT centers. Elevated distress was reported by 32% of patients, impaired physical function by 19%, and both by 12%. Driving distance, whether operationalized as a continuous or dichotomous variable, had no impact on distress or physical function in linear regression modeling (95% confidence interval, 1.00 to 1.00, for both PROs with driving distance as a continuous variable). In contrast, chronic graft-versus-host-disease, lower income, and lack of Internet access independently predicted both elevated distress and impaired physical function. In summary, we found no impact of driving distance on distress and physical function among HCT survivors. Our results have implications for how long-term follow-up care is delivered after HCT, with regard to the negligible impact of driving distances on PROs and also the risk of a "digital divide" worsening outcomes among HCT survivors without Internet access.

Who Enrolls in an Online Cancer Survivorship Program? Reach of the INSPIRE Randomized Controlled Trial for Hematopoietic Cell Transplantation Survivors.

The internet can be a valuable tool in delivering survivorship care to hematopoietic cell transplantation (HCT) cancer survivors. We describe the reach of INSPIRE, an Internet and social media-based randomized controlled trial, to address healthcare and psychosocial needs of HCT survivors. All survivors 2-10 years after HCT for hematologic malignancy or myelodysplasia from 6 transplantation centers in the US were approached by mail and follow-up calls. Eligible participants had access to the Internet, an email address, and did not have active disease in the past 2 years. We used logistic regression to determine characteristics of eligible survivors who were more or less likely to enroll. Of 2578 eligible HCT survivors, 1065 (41%) enrolled in the study. The mean age of enrollees was 56.3 ± 12.6 years (range, 19 to 89 years), 52% were male, and 94% were white. Survivors less likely to enroll included those who were male, age <40 years, and who received an autologous transplant (all P < .001). Compared with white survivors, African Americans were less likely to enroll (P < .001), whereas Native Americans/Alaska Natives were more likely to join the study (P = .03). The reach of the INSPIRE program was broad, including to survivors who traditionally have less access to resources, such as Native Americans/Alaskan Natives and rural residents. Strategies are still needed to improve the enrollment of online studies of survivorship resources for males, young adults, African American, and autologous HCT survivors because their use may improve outcomes.

Survivorship after Autologous Hematopoietic Cell Transplantation for Lymphoma and Multiple Myeloma: Late Effects and Quality of Life.

Although autologous hematopoietic cell transplantation (AHCT) is standard therapy for patients with lymphoma and multiple myeloma (MM), few studies have addressed late effects and quality of life (QoL) in long-term survivors after AHCT. Using long-term follow-up (LTFU) annual questionnaires with self-reported outcomes, we surveyed 665 patients who were at ≥5 years after AHCT for the diagnosis of lymphoma or MM. Three-hundred and eighty-nine patients completed the questionnaire (58% response rate) at a median of 11 years (range, 5-30 years) after AHCT. The median patient age was 63 years (range, 22-88 years) in the 268 patients with lymphoma and 69 years (range, 34-84 years) in the 121 patients with multiple myeloma. The most commonly reported medical conditions (>10% incidence) were sexual dysfunction, history of shingles, cataracts, osteoporosis or osteopenia, joint replacement, and skin cancer. Current medication use was more frequent in the patients with MM for infection prevention/treatment (19% for MM versus 5% lymphoma; P < .001), hypertension (41% versus 26%; P = .004), osteoporosis (23% versus 10%; P < .001), and pain (32% versus 11%, P < .001). Treated hypothyroidism was more common in lymphoma patients. In multivariate analysis combining lymphoma and MM, worse physical functioning was associated with older age, shorter interval since AHCT, comorbidities, relapse, and treatment for depression and/or pain. Worse mental functioning was associated with younger age and treatment for anxiety, depression, or pain. In conclusion, AHCT survivors report generally good QoL but many late effects and symptoms that are potentially amenable to intervention.

Factors associated with social functioning among long-term cancer survivors treated with hematopoietic stem cell transplantation as adolescents or young adults.

OBJECTIVE: Hematopoietic stem cell transplantation (HSCT) can compromise long-term health and social functioning. We examined the impact of physical and social-emotional factors on the social functioning of long-term adolescent and young adult (AYA) HSCT survivors. METHODS: This cross-sectional analysis included HSCT recipients from the INSPIRE trial [NCT00799461] who received their first transplant between ages 15-39. Patient-reported outcome measures included the Short Form-36v2, Fatigue Symptom Inventory, Cancer and Treatment Distress, and the ENRICHD Social Support Inventory. We used hierarchical multiple linear regression to identify physical and social-emotional factors associated with social functioning at the baseline assessment, with the first block including sociodemographic and clinical factors significant at P = <0.10 in univariate testing, the second block including fatigue and physical function, and the third block including social support and distress. RESULTS: Participants (N = 279) were 52% male and 93.5% white, non-Hispanic, with a mean age of 30.3 (SD 6.6) at first transplant. Social Functioning mean was 48.5 (SD 10.5), below age-adjusted norms (t = -13.6, P = <0.001). In the first block, current chronic graft-vs-host disease accounted for 5.5% of the variance (P = <0.001). Adding fatigue and physical function explained an additional 46.6% of the variance (P = <0.001). Adding distress and social support explained an additional 7.7% of the variance (P = <0.001). The final model explained 59.8% of the variance; distress, fatigue, and physical function were significantly associated with social functioning. CONCLUSIONS: Distress, fatigue, and physical function are associated with social functioning and interventions targeting these symptoms may help to improve SF among long-term cancer survivors treated with HSCT as AYAs.

Engaging hematopoietic cell transplantation patients and caregivers in the design of print and mobile application individualized survivorship care plan tools.

PURPOSE: INSPIRE (INteractive Survivorship Program with Information and REsources) is an online health program that includes a mobile app, website, health action plan, and individualized survivorship care plans for adult hematopoietic cell transplant (HCT) survivors. The INSPIRE program integrates two previously effective randomized control trials that tested an internet-based program and patient-centered survivorship care plans for HCT survivors. METHODS: Three focus groups were conducted with a total of 22 participants (20 patients, 2 caregivers/patient advocates) to explore patient and caregiver preferences and to optimize the patient-centered emphasis of INSPIRE. Adult (age > 18 years at the time of study entry) HCT recipients had to be at least 1-year post-HCT to participate; caregivers/patient advocates were also eligible. Participants had to be able to communicate in English, could have any diagnosis, transplant type, or donor source, and could have had multiple transplants. RESULTS: All patient participants received an allogeneic HCT; average time since HCT was 8 years (range 2-22 years). The majority of participants were female (77.3%). Overall, the tools were well received by participants in this study, particularly the personalized features of all the tools. Major themes included interest in having the ability to tailor features to individual needs, and an interest in tracking information over time. DISCUSSION: Engaging patients and caregivers is invaluable to optimize tools designed to improve HCT survivorship care. Print, online, and mobile-based tools, tailored to individual patients' treatment history and requisite follow-up care, can provide otherwise unavailable expertise and guidelines for care.

Age and gender differences in financial distress among hematopoietic cell transplant survivors.

PURPOSE: Cancer has long-term financial consequences. Adolescent and young adult (AYA) and middle-aged cancer survivors may experience more financial toxicity than older adults. This study examined age differences in financial distress in hematopoietic cell transplant survivors and whether these differences result from measurement bias, more financial barriers to care, or an overall higher level of distress. METHODS: Hematologic malignancy survivors (n = 1135, 2-10 years post-transplant) completed the Cancer and Treatment Distress Scale (CTXD) and demographics as part of the baseline assessment for a randomized clinical trial. The CTXD has seven subscales, but for this study, we examined the financial distress subscale and the overall score. Item response theory analyses tested for bias by age and gender. Multivariate linear regression tested the association of age and gender with the CTXD scores while controlling for financial barriers to care. RESULTS: No bias was found on the CTXD. AYA (p < 0.01) and middle-aged adults (p < 0.001) reported more financial and overall distress than older (age 65+) adults. The same association of age and financial distress was observed in women (p < 0.01). However, only middle-aged men (p < 0.01) reported more financial and overall distress than older men; AYA men did not (p > 0.18). Financial barriers to care were not associated with financial or overall distress. CONCLUSIONS: Part of the increase in financial distress with younger age may be due to a higher risk of general distress. Policy initiatives to control cancer costs should consider life stage and the unique financial challenges at different ages for men and women.

Application of the ConNECT Framework to Precision Health and Health Disparities.

BACKGROUND: An emphasis on precision health (PH) has stimulated precision medicine studies to focus on the interplay of biological, behavioral, and environmental factors with disease risks, treatments, prognoses, and outcomes affecting health disparities. It is imperative, as well, that improving health equity among underserved populations remains central to the efforts and aims of PH. OBJECTIVES: The aim if this study was to apply the transdisciplinary ConNECT Framework: A Model for Advancing Behavioral Medicine Science and Practice to Foster Health Equity to PH by integrating a population health agenda for reducing health disparities. METHODS: There are five ConNECT principles: (a) integrating context; (b) fostering a norm of inclusion; (c) ensuring equitable diffusion of innovations; (d) harnessing communication technology; and (e) prioritizing specialized training as an organizing framework to PH, including examples of how to integrate behavioral and socioecological determinants to better understand the contexts of individuals, systems, and place to design targeted treatments and interventions. RESULTS: We describe proactive, actionable strategies for the systematic application of ConNECT Framework principles to address health equity via the PH initiative. Context and implications for nursing research and practice are also described. DISCUSSION: The ConNECT Framework emphasizes that diversity inclusion is imperative for true population health benefit from PH, broadly in public health, behavioral medicine, medicine, and nursing, to equip health researchers and practitioners to account for contextual socioecologic data that can be aligned with biologic data for more population responsive and individually tailored interventions to prevent, diagnose, and treat diseases.

Engagement with INSPIRE, an Online Program for Hematopoietic Cell Transplantation Survivors.

In a secondary analysis of a randomized controlled trial (RCT), we examined participants' engagement with INSPIRE, a personalized online program for hematopoietic cell transplantation (HCT) survivors that focuses on cancer-related distress, depression, fatigue, and health care needs. We approached all adult, 3- to 18-year HCT survivors treated for hematologic malignancy without relapse or second cancer in the previous 2 years for participation in an RCT with either immediate or delayed access to INSPIRE. Participants with immediate access could view the online material at any time. Data included page view tracking, medical records, and patient-reported outcomes, including the Short Form 36 and Cancer and Treatment Distress (CTXD) measures. Of 1322 eligible HCT survivors, 771 (58%) completed the baseline assessment, and 451 received immediate INSPIRE access and were included in analyses. The cohort was 56% male, with a mean age of 52 ± 12.2 years, and 26% received an autologous transplant. Most (77%) logged into the INSPIRE site at least once, and 48% viewed ≥8 pages. Survivors who viewed ≥2 pages were more likely to be age ≥40 years (relative risk [RR], 1.41; 95% confidence interval [CI], 1.10 to 1.80), to be female (RR, 1.22; 95% CI, 1.07 to 1.40), to have chronic graft-versus-host disease (RR, 1.28; 95% CI, 1.08 to 1.51), to be less than 10 years post-HCT (RR, 1.19; 95% CI, 1.01 to 1.39), and to have moderate CTXD distress (RR, 1.34; 95% CI, 1.14 to 1.57). Engagement did not differ by race, education, income, rural/urban residence, computer experience, donor type, or depression (all P ≥ .50). The INSPIRE online program was widely used, including by those who often have reduced access to care after treatment.

Neurocognitive Dysfunction in Hematopoietic Cell Transplant Recipients: Expert Review from the Late Effects and Quality of Life Working Committee of the Center for International Blood and Marrow Transplant Research and Complications and Quality of Life Working Party of the European Society for Blood and Marrow Transplantation.

Hematopoietic cell transplantation (HCT) is a potentially curative treatment for children and adults with malignant and nonmalignant diseases. Despite increasing survival rates, long-term morbidity after HCT is substantial. Neurocognitive dysfunction is a serious cause of morbidity, yet little is known about neurocognitive dysfunction after HCT. To address this gap, collaborative efforts of the Center for International Blood and Marrow Transplant Research and the European Society for Blood and Marrow Transplantation undertook an expert review of neurocognitive dysfunction after HCT. In this review we define what constitutes neurocognitive dysfunction, characterize its risk factors and sequelae, describe tools and methods to assess neurocognitive function in HCT recipients, and discuss possible interventions for HCT patients with this condition. This review aims to help clinicians understand the scope of this health-related problem, highlight its impact on well-being of survivors, and help determine factors that may improve identification of patients at risk for declines in cognitive functioning after HCT. In particular, we review strategies for preventing and treating neurocognitive dysfunction in HCT patients. Finally, we highlight the need for well-designed studies to develop and test interventions aimed at preventing and improving neurocognitive dysfunction and its sequelae after HCT.

The Impact of Written Emotional Disclosure on Cancer Caregivers' Perceptions of Burden, Stress, and Depression: A Randomized Controlled Trial.

Spousal cancer caregivers' emotional and relational health can become compromised over time due to ongoing challenges related to the cancer experience. This warrants a call for the assessment of interventions aimed at improving aspects of caregiver well-being. The current study employed a randomized controlled trial to determine whether emotional disclosure via the use of expressive writing improved spousal cancer caregivers' perceived caregiver burden, stress, and depression. Participants (N = 64) were assigned to one of the two disclosure conditions: expressive disclosure or benefit finding-or to a time-management control condition. Participants completed three at-home writing sessions at one-week intervals. Results indicated that written forms of emotional disclosure might improve burden, stress, and depression contingent on writing condition. Specifically, both forms of emotional disclosure outperformed the control condition in reducing caregivers' depression. The control condition outperformed treatments in reducing caregiver stress. Finally, posttest caregiver burden was significantly lower than pretest burden across all writing conditions. This trial was registered with clinicaltrials.gov, ID: NCT02339870.

Photocatalytic conversion of ethylenediaminetetraacetic acid dissolved in real electroplating wastewater to hydrogen in a solar light-responsive system.

A sustainable and multifunctional photocatalysis-based technology has been established herein for simultaneous hydrogen generation and oxidation of ethylenediaminetetraacetic acid (EDTA) in real electroplating wastewater. When the photocatalyst concentration was 4 g/L and electroplating wastewater pH was 6, optimal adsorptions of EDTA2-, H+, and H2O were observed, while hydrogen generation efficiency reached 305 µmol/(h g). Owing to EDTA oxidation and occupation of the active sites of the photocatalyst by Ni ions or Ni-EDTA chelates, the charge separation and adsorptions of H+ and H2O decreased, reducing hydrogen generation efficiency with time. The lower EDTA and Ni concentrations in treated wastewater showed that photocatalytic conversion of EDTA in real electroplating wastewater to enhance hydrogen generation efficiency can be a practical alternative energy production technology. This study provided a novel idea to enhance the value of electroplating wastewater, to build a hydrogen generation route with no consumption of a valuable resource, and to reduce EDTA and Ni concentrations in electroplating wastewater.

Cancer and treatment distress psychometric evaluation over time: A BMT CTN 0902 secondary analysis.

BACKGROUND: Routine monitoring of cancer-related distress is recognized as essential to quality care and mandated by a major accrediting organization. However, to the authors' knowledge, few cancer-specific measures have been developed to date to assess the multiple cancer-related factors contributing to this distress. In the current study, the authors examined the psychometric properties of the Cancer and Treatment Distress (CTXD) measure over time in hematopoietic cell transplantation (HCT) recipients. METHODS: As a secondary analysis of a multicenter randomized controlled clinical trial, adult patients undergoing autologous or allogeneic HCT completed patient-reported outcomes including the CTXD and the Medical Outcomes Study Short Form-36 (SF-36) before transplantation and 100 days and 180 days after HCT. RESULTS: Across 21 transplantation centers, a total of 701 patients consented, underwent transplantation, and were included in the current analyses, 645 of whom were alive at 100 days and 618 of whom were alive at 180 days. Internal consistency reliability was found to be strong for the overall CTXD at the 3 time points: Cronbach alphas (α) were .94, .95, and .95, respectively. Subscale reliability met hypothesized levels of an α>.70 across time, with the lowest reliability noted for the Identity subscale at 180 days (α = .77). Correlations with the SF-36 Mental Health subscale were higher than with the Physical Functioning subscale at each time point, thereby supporting convergent and discriminant validity. Strong correlations of the pretransplantation CTXD with the posttransplantation CTXD and SF-36 Mental Health subscale supported predictive validity. CONCLUSIONS: The CTXD is reliable and valid as a measure of cancer distress both before and after HCT. It may be a useful tool for measuring dimensions of distress and for defining those patients requiring treatment for distress during and after transplantation.

The ConNECT Framework: a model for advancing behavioral medicine science and practice to foster health equity.

Health disparities persist despite ongoing efforts. Given the United States' rapidly changing demography and socio-cultural diversity, a paradigm shift in behavioral medicine is needed to advance research and interventions focused on health equity. This paper introduces the ConNECT Framework as a model to link the sciences of behavioral medicine and health equity with the goal of achieving equitable health and outcomes in the twenty-first century. We first evaluate the state of health equity efforts in behavioral medicine science and identify key opportunities to advance the field. We then discuss and present actionable recommendations related to ConNECT's five broad and synergistic principles: (1) Integrating Context; (2) Fostering a Norm of Inclusion; (3) Ensuring Equitable Diffusion of Innovations; (4) Harnessing Communication Technology; and (5) Prioritizing Specialized Training. The framework holds significant promise for furthering health equity and ushering in a new and refreshing era of behavioral medicine science and practice.

Behavior change interventions: the potential of ontologies for advancing science and practice.

A central goal of behavioral medicine is the creation of evidence-based interventions for promoting behavior change. Scientific knowledge about behavior change could be more effectively accumulated using "ontologies." In information science, an ontology is a systematic method for articulating a "controlled vocabulary" of agreed-upon terms and their inter-relationships. It involves three core elements: (1) a controlled vocabulary specifying and defining existing classes; (2) specification of the inter-relationships between classes; and (3) codification in a computer-readable format to enable knowledge generation, organization, reuse, integration, and analysis. This paper introduces ontologies, provides a review of current efforts to create ontologies related to behavior change interventions and suggests future work. This paper was written by behavioral medicine and information science experts and was developed in partnership between the Society of Behavioral Medicine's Technology Special Interest Group (SIG) and the Theories and Techniques of Behavior Change Interventions SIG. In recent years significant progress has been made in the foundational work needed to develop ontologies of behavior change. Ontologies of behavior change could facilitate a transformation of behavioral science from a field in which data from different experiments are siloed into one in which data across experiments could be compared and/or integrated. This could facilitate new approaches to hypothesis generation and knowledge discovery in behavioral science.

Changes of geriatric syndromes in older adults survived from Intensive Care Unit.

Nearly 90% of the older adult patients discharged from hospital with a cluster of geriatric syndromes. The patterns of geriatric syndromes in older adult ICU survivors are to be further explored. The aim of this study was to examine the risk factors and patterns of geriatric syndromes among older adult patients before admitting to ICU and throughout their hospitalization. A total of 137 older adult patients (age 76.9 ± 6.6; 52.6% male) participated in the study. The results showed significant increase in the occurrence of geriatric syndromes from T0 (upon ICU admission) to T1 (transition to inpatient care unit), with improvement at T2 (hospital discharge), but did not return to the baseline. The three most prevalent geriatric syndromes were: functional decline, urination incontinence, and defecation incontinence. Polypharmacy was associated with functioning decline. Patients with delirium were six times more likely to be re-admitted to ICU.

Developing a Risk Prediction Model for Long-Term Physical and Psychological Functioning after Hematopoietic Cell Transplantation.

Hematopoietic cell transplantation (HCT) is associated with impaired physical and psychological functioning for some long-term survivors. A risk prediction model would help clinicians estimate their patients' physical and psychological functioning after HCT and determine when to refer to added supportive care when appropriate. The purpose of the present study was to develop risk prediction models for physical and psychological functioning in HCT survivors. This was a secondary analysis of data from a randomized controlled trial (NCT00799461) that included 3- to 10-year HCT survivors. Risk predictions for physical and psychological functioning were developed by using backward logistic regression. The models were internally validated using bootstrapping techniques. Regression coefficients were converted into easy-to-use risk scores. Finally, the sensitivity, specificity, and positive and negative predictive values of the total risk score were calculated. The analyses included 489 survivors, with a mean age of 45.6 (SD, 12.4) years; 47% were female and with a mean of 6.1 years (SD, 2.0) after transplantation. Younger age, higher body mass index (BMI), no or part-time work, more comorbid diseases, autologous transplantation, and chronic graft-versus-host disease predicted impaired physical functioning. Female gender, younger age, higher BMI, not living with a partner, autologous transplantation, and chronic graft-versus-host disease predicted impaired psychological functioning. Although both models had predictive value for long-term functioning, diagnostic accuracy was moderate. For the physical functioning receiver operating characteristic, area under the curve (AUC) after internal validation was .74 with sensitivity 51.9 and specificity 82.8 at the optimal cut-off. For psychological functioning, AUC after internal validation was .69 with sensitivity 83.3 and specificity 42.9 at the optimal cut-off. We conclude that it is possible to predict long-term physical and psychological functioning with readily accessible, mostly pretransplantation predictors. The accuracy of the risk prediction models can be improved for use in clinical practice, potentially by adding pretransplantation patient-reported functioning and comorbidities.

Psychometric properties of the Cancer and Treatment Distress (CTXD) measure in hematopoietic cell transplantation patients.

BACKGROUND: This study examines the psychometric properties of a measure of distress specific to cancer and its treatment, as tested in patients receiving hematopoietic cell transplantation (HCT). METHODS: With multicenter enrollment, the Cancer and Treatment Distress (CTXD) measure was administered to adults beginning HCT as part of an assessment that included the Center for Epidemiologic Studies Depression (CESD), Profile of Mood States, and Medical Outcomes Study Short Form 36 (SF-36). RESULTS: From eight transplant centers, 176 of 219 eligible patients completed the assessment. Average age was 46.7 years (SD = 11.9), 59% were male, and the majority were identified as Caucasian (93%). Principal components analysis with the CTXD identified 22 items that loaded onto six factors explaining 69% of the variance: uncertainty, health burden, identity, medical demands, finances, and family strain. Internal consistency reliability for the 22 items was 0.91. The receiver operating characteristic area under the curve was 0.85 (95% CI [0.79, 0.91]), with a cut point of 1.1 resulting in a sensitivity rate of 0.91 and a specificity rate of 0.58. Convergent validity and divergent validity were confirmed with large correlations of the CTXD total score with the CESD, Profile of Mood States, and SF-36 mental health; and a smaller correlation with the SF-36 physical function (r = -0.30). CONCLUSIONS: The CTXD is a reliable and valid measure of distress for HCT recipients and captures nearly all cases of depression on the CESD in addition to detecting distress in those who are not depressed. It has potential value as both a research and clinical screening measure for distress.
