The Effect of Self-efficacy-Enhancing Interventions on Quality of Life of Cancer Survivors: A Systematic Review.

BACKGROUND: The influence of self-efficacy-enhancing interventions on quality of life (QOL) is not clear with recent randomized controlled trials (RCTs) because current reviews only evaluated self-efficacy as an outcome. OBJECTIVES: We conducted a systematic review to examine the effect of self-efficacy-enhancing interventions on QOL among patients with cancer and to summarize the effective determinants for designing self-efficacy-enhancing interventions. METHODS: A systematic search was performed on studies published from January 2003 to May 2023 using PubMed, CINAHL, PsycINFO, and Web of Science. Included studies were RCTs, adults diagnosed with cancer, interventions with explicit self-efficacy components, and QOL as the outcome. RESULTS: Nineteen RCTs were included. Risk-of-bias assessment revealed 12 studies with some concerns and 7 with high risk of bias. The mean intervention adherence rate was 88.2%; the most frequently listed reason for dropout was medical conditions and mortality. Self-efficacy interventions were shown to significantly improve at least 1 subscale of QOL in 9 of 19 studies, of which 7 studies used Bandura's 4 sources of self-efficacy. The interventions with between-session intervals shorter than 2 weeks, of 12-week duration, and with an in-person delivery approach were the most effective. CONCLUSIONS: Self-efficacy-enhancing interventions show potential beneficial effects on QOL among cancer survivors. Interventions that use Bandura's 4 sources of self-efficacy strategies and have between-session intervals shorter than 2 weeks, an in-person approach, and 12-week intervention duration are recommended. IMPLICATIONS FOR PRACTICE: Properly designed self-efficacy-enhancing interventions can facilitate behavioral change and improve QOL in cancer survivors.

Cognitive intra-individual variability in breast cancer survivors: A systematic review.

Subjective and objective cognitive impairments in Breast Cancer Survivors (BCS) often do not correlate. One important contribution to the reported disparities may be the reliance on mean-based cognitive performance. Cognitive intra-individual variability (IIV) may provide important insights into these reported disparities. Cognitive IIV refers to the fluctuation in performance for an individual on either one cognitive task across a trial or dispersed across tasks within a neuropsychological test battery. The purpose of this systematic review was to search for and examine the literature on cognitive IIV in BCS. The PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) approach was used to search for all articles related to cognitive IIV in BCS. MEDLINE (via PubMed), Embase, and Scopus databases were searched using detailed search terms and strategies. Initially, 164 articles were retrieved but only 4 articles met the criteria for this systematic review. BCS differed from healthy controls in similar ways across the four studies, generally demonstrating similar performance but showing increased cognitive IIV for the more difficult tasks. Differences were enhanced later during chemotherapy. The four studies provide support for cognitive IIV as a useful measure to detect the subtle objective cognitive change often reported by BCS but frequently not detected by standard normed-based cognitive testing. Unexpectedly, measures of cognitive IIV were not consistently associated with self-reported measures of cognition.

Fatigue-related symptom clusters and functional status of older adults in hospice.

BACKGROUND: Fatigue is frequently co-existing with other symptoms and is highly prevalent among patients with cancer and geriatric population. There was a lack of knowledge that focus on fatigue clusters in older adults with cancer in hospice care. OBJECTIVES: To identify fatigue-related symptom clusters in older adult hospice patients and discover to what extent fatigue-related symptom clusters predict functional status while controlling for depression. METHOD: This was a cross-sectional study in a sample of 519 older adult hospice patients with cancer, who completed the Memorial Symptom Assessment Scale, the Center for Epidemiological Studies Depression, Boston Short Form Scale, and the Palliative Performance Scale. Data from a multi-center symptom trial were extracted for this secondary analysis using exploratory factor analysis and hierarchical multiple regression analysis. RESULTS: Data from 519 patients (78 ± 7 years) with terminal cancer who received hospice care under home healthcare services revealed that 39% of the participants experienced fatigue-related symptom clusters (lack of energy, feeling drowsy, and lack of appetite). The fatigue cluster was significantly associated positively with depression (r = 0.253, p < 0.01), and negatively with functional status (r = -0.117, p < 0.01) and was a strong predictor of participants' low functional status. Furthermore, depression made a significant contribution to this predictive relationship. CONCLUSION: Older adult hospice patients with cancer experienced various concurrent symptoms. The fatigue-specific symptom cluster was identified significantly associated with depression and predicted functional status. Fatigue should be routinely monitored in older adults, especially among hospice cancer patients, to help reduce psychological distress and prevent functional decline.

Computer-tailored intervention increases colorectal cancer screening among low-income African Americans in primary care: Results of a randomized trial.

INTRODUCTION: Although African Americans have the highest colorectal cancer (CRC) incidence and mortality rates of any racial group, their screening rates remain low. STUDY DESIGN/PURPOSE: This randomized controlled trial compared efficacy of two clinic-based interventions for increasing CRC screening among African American primary care patients. METHODS: African American patients from 11 clinics who were not current with CRC screening were randomized to receive a computer-tailored intervention (n = 335) or a non-tailored brochure (n = 358) designed to promote adherence to CRC screening. Interventions were delivered in clinic immediately prior to a provider visit. Univariate and multivariable logistic regression models analyzed predictors of screening test completion. Moderators and mediators were determined using multivariable linear and logistic regression analyses. RESULTS: Significant effects of the computer-tailored intervention were observed for completion of a stool blood test (SBT) and completion of any CRC screening test (SBT or colonoscopy). The colonoscopy screening rate was higher among those receiving the computer-tailored intervention group compared to the nontailored brochure but the difference was not significant. Predictors of SBT completion were: receipt of the computer-tailored intervention; being seen at a Veterans Affairs Medical Center clinic; baseline stage of adoption; and reason for visit. Mediators of intervention effects were changes in perceived SBT barriers, changes in perceived colonoscopy benefits, changes in CRC knowledge, and patient-provider discussion. Moderators of intervention effects were age, employment, and family/friend recommendation of screening. CONCLUSION: This one-time computer-tailored intervention significantly improved CRC screening rates among low-income African American patients. This finding was largely driven by increasing SBT but the impact of the intervention on colonoscopy screening was strong. Implementation of a CRC screening quality improvement program in the VA site that included provision of stool blood test kits and follow-up likely contributed to the strong intervention effect observed at that site. The trial is registered at ClinicalTrials.gov as NCT00672828.

The pre-efficacy phase testing for PAfitME™-A behavioral physical activity intervention to manage moderate and severe symptoms among advanced stage cancer patients.

Fatigue and pain are the most frequently reported symptoms among advanced-stage cancer patients. Although physical activity (PA) is known to improve the aforementioned symptoms, few patients demonstrate the physically active behavior that adheres to the clinical guidelines regarding PA. The current article presents an exemplar that used the National Institute of Health's Obesity-Related Behavioral Intervention Trial (ORBIT) model and developed a behavioral intervention known as the personalized Physical Activity intervention with fitness graded Motion Exergames (PAfitME™). There were two phases of testing in the ORBIT model presented in the current paper. In Phase I testing, a standardized exergame prescription was evaluated by an advisory board and a single-case study was used to evaluate the personalized exergame prescription with personalization of the fitness levels. In Phase IIa, a within-group pre- and posttest design was used to evaluate the personalized exergame prescriptions with personalization of the fitness levels, self-efficacy, and variation in fatigue/pain. Subsequently, a complete intervention package was developed in accordance with a logic model, driven from the result of the Phase IIa testing with clinically significant findings. Currently, PAfitME™ is under Phase IIb testing in a randomized clinical trial with a control group. PAfitME™ employs a personalized approach to initiate and promote physically active behavior, to facilitate the management of fatigue and pain in cancer patients. Positive results from an efficacy trial would support the use of PAfitME™ in the management of fatigue and pain in advanced-stage cancer patients.

Systematic Review of Interventions to Increase Stool Blood Colorectal Cancer Screening in African Americans.

African Americans experience colorectal cancer (CRC) related disparities compared to other racial groups in the United States. African Americans are frequently diagnosed with CRC at a later stage, screening is underutilized, and mortality rates are highest in this group. This systematic review focused on intervention studies using stool blood CRC screening among African Americans in primary care and community settings. Given wide accessibility, low cost, and ease of dissemination of stool-based CRC screening tests, this review aims to determine effective interventions to improve participation rates. This systematic review included intervention studies published between January 1, 2000 and March 16, 2019. After reviewing an initial search of 650 studies, 11 studies were eventually included in this review. The included studies were studies conducted in community and clinical settings, using both inreach and outreach strategies to increase CRC screening. For each study, an unadjusted odds ratio (OR) for the CRC screening intervention compared to the control arm was calculated based on the data in each study to report effectiveness. The eleven studies together recruited a total of 3334 participants. The five studies using two-arm experimental designs ranged in effectiveness with ORs ranging from 1.1 to 13.0 using interventions such as mailed reminders, patient navigation, and tailored educational materials. Effective strategies to increase stool blood testing included mailed stool blood tests augmented by patient navigation, tailored educational materials, and follow-up calls or mailings to increase trust in the patient-provider relationship. More studies are needed on stool blood testing interventions to determine effectiveness in this population.

Exercise Interventions in Cardio-Oncology Populations: A Scoping Review of the Literature.

BACKGROUND: Cardiac toxicity in patients with cancer results from treatment-related damage to the cardiovascular system by chemotherapy, targeted agents, or thoracic radiation. Cardio-oncology patients with co-occurring cancer and cardiovascular disease frequently experience fatigue. Exercise is recommended in clinical guidelines to manage fatigue during or after cancer treatment. PURPOSE: The purpose of this article is to conduct a scoping review of the exercise randomized clinical trials in cardio-oncology patients, focusing on the components and effects of exercise interventions on patient cardiovascular and fatigue outcomes. METHODS: A scoping review methodological framework was deemed appropriate and used. Key words for search included "cancer," "oncology," "cardio-oncology," "heart failure," "physical activity," and "exercise." Search involved systematic searches of large databases (PubMed, MEDLINE, Cochrane Review, and CINAHL) and hand searches of reference lists, key journals, webpages, and experts in the field using snowballing techniques. RESULTS: There were 12 randomized clinical trials included in this review. Study characteristics, accordance of exercise protocols with recommendations, specific exercise training components, and cardiovascular and fatigue outcomes were mapped. CONCLUSIONS: Recommendations for addressing the gaps included focusing on non-breast-cancer patients with cardiac toxicity risks, developing precision-based prescriptions based on various medical and physiological characteristics, and adding fatigue symptom experience as an outcome variable.

Examining the Relationship Between Patient Fatigue-Related Symptom Clusters and Carer Depressive Symptoms in Advanced Cancer Dyads: A Secondary Analysis of a Large Hospice Data Set.

BACKGROUND: Most symptom management takes place in the community, conducted by patient and/or informal carer dyads with guidance from clinicians. Given the prevalence of cancer, there is a critical need for examination of the impact of managing multiple symptoms, particularly those that cluster with fatigue, on informal carers. OBJECTIVES: To (1) examine clustering of patient fatigue-related symptom severity and distress in individuals with cancer and (2) test the hypothesis that patient fatigue-related symptom clusters (severity, distress) will be positively associated with carer depressive symptoms. METHODS: Secondary analysis of 689 hospice patient/informal carer dyads using exploratory factor analysis and structural equation modeling. Patient symptoms were measured by the Memorial Symptom Assessment Scale, and carer depressive symptoms were measured by the Center for Epidemiological Study-Depression Scale. RESULTS: Patients were 73 (SD, 12) years old, and 43% were female. Carers were 65 years (SD, 14) years old, and 74% were female. For symptom severity, dyspnea, dry mouth, lack of appetite, drowsiness, cough, dizziness, and difficulty swallowing clustered with fatigue. For symptom distress, dyspnea, cough, and dry mouth clustered with fatigue. Structural equation modeling results indicated that the patient fatigue severity cluster was positively related to carer depressive symptoms (b = 0.12, P < .05), but distress was not. CONCLUSION: Managing multiple symptoms that cluster with fatigue negatively impacts informal carers. IMPLICATIONS FOR PRACTICE: When patients complain of severe fatigue, clinicians need to explore all causes and ask about other symptoms while exploring whether the informal carer is feeling burdened or depressed.

Cancer Pain and Quality of Life.

Cancer pain is an unrelenting symptom with the potential to alter the quality of life of patients. To adequately manage pain, nurses caring for cancer patients need to fully understand each patient's pain experience. The purpose of this study was to identify the intensity, distress, frequency, or constancy of pain in patients treated for cancer or cancer symptoms and to better understand patient barriers to pain management. This cross-sectional study included patients (N = 105) treated for cancer or cancer symptoms at 2 outpatient medical centers. Assessments included the Pain Barriers Scale, the Cancer Symptom Scale, and the Multidimensional QOL Scale-Cancer. Descriptive statistics and Spearman correlations were used to analyze the data. Sixty-nine percent of patients reported present pain of moderate to severe intensity that caused distress, was frequent/constant, or interfered with their lives. Patients with the greatest pain distress reported the greatest intensity of pain (r = 0.77) and the greatest interference (r = 0.78) with daily lives. Cancer pain was associated with significant distress and interference with life activities and occurred frequently or constantly for many study patients.

A Behavioral Physical Activity Intervention to Manage Moderate and Severe Fatigue Among Head and Neck Cancer Patients-Pre-efficacy Study in the National Institutes of Health ORBIT Model.

BACKGROUND: Cancer-related fatigue (CRF) reduces head and neck cancer (HNC) survival rates and is the most common, severe, and distressing symptom negatively impacting activities of daily living (ADLs) dependence among HNC patients. These patients remain physically inactive after their cancer treatment, although there is consensus that physical activity mitigates CRF in cancer patients. OBJECTIVE: A home-based personalized behavioral physical activity intervention with fitness graded motion exergames (PAfitME) was evaluated for its intervention components, intervention delivery mode, and intervention contact time/duration with initial assessment of the feasibility, acceptability, safety, and outcomes. METHODS: This study (N = 8) was a single-group, pre-post design to evaluate a 6-week PAfitME at the end of HNC treatment. Health outcomes were CRF, ADL dependence, and fitness performance. Behavioral outcomes were exergame adherence. RESULTS: Positive health and behavioral outcomes support the PAfitME protocol including intervention components, intervention delivery mode, and intervention contact times/duration. The PAfitME intervention is feasible and acceptable with promising adherence rates. No adverse events were reported. There was marked improvement in CRF, ADL dependence, cardiorespiratory fitness, balance, muscle strength, and shoulder forward flexion, with large to moderate effect sizes as a result of the PAfitME intervention. CONCLUSION: The PAfitME protocol is ready for additional testing in a randomized clinical trial. IMPLICATIONS FOR PRACTICE: The PAfitME intervention is a nurse-led nonpharmacological intervention. It can be integrated into home care or telehealth care for HNC patients at the end of their cancer treatment once effectiveness is established.

Understanding Cancer Worry Among Patients in a Community Clinic-Based Colorectal Cancer Screening Intervention Study.

BACKGROUND: To reduce colorectal cancer (CRC) screening disparities, it is important to understand correlates of different types of cancer worry among ethnically diverse individuals. OBJECTIVES: The current study examined the prevalence of three types of cancer worry (i.e., general cancer worry, CRC-specific worry, and worry about CRC test results) as well as sociodemographic and health-related predictors for each type of cancer worry. METHODS: Participants were aged 50-75, at average CRC risk, nonadherent to CRC screening guidelines, and enrolled in a randomized controlled trial to increase CRC screening. Participants completed a baseline questionnaire assessing sociodemographics, health beliefs, healthcare experiences, and three cancer worry measures. Associations between study variables were examined with separate univariate and multivariable logistic regression models. RESULTS: Responses from a total of 416 participants were used. Of these, 47% reported experiencing moderate-to-high levels of general cancer worry. Predictors of general cancer worry were salience and coherence (aOR = 1.1, 95% CI [1.0, 1.3]), perceived susceptibility (aOR = 1.2, 95% CI [1.1, 1.3), and social influence (aOR = 1.1, 95% CI [1.0, 0.1]). Fewer (23%) reported moderate-to-high levels of CRC-specific worry or CRC test worry (35%). Predictors of CRC worry were perceived susceptibility (aOR = 1.4, 95% CI [1.3, 1.6]) and social influence (aOR = 1.1, 95% CI [1.0, 1.2]); predictors of CRC test result worry were perceived susceptibility (aOR = 1.2, 95% CI [1.1, 1.3) and marital status (aOR = 2.0, 95% CI [1.1, 3.7] for married/partnered vs. single and aOR = 2.3, 95% CI [1.3, 4.1] for divorced/widowed vs. single). DISCUSSION: Perceived susceptibility consistently predicted the three types of cancer worry, whereas other predictors varied between cancer worry types and in magnitude of association. The three types of cancer worry were generally predicted by health beliefs, suggesting potential malleability. Future research should include multiple measures of cancer worry and clear definitions of how cancer worry is measured.

Feasibility of the mobile mindfulness-based stress reduction for breast cancer (mMBSR(BC)) program for symptom improvement among breast cancer survivors.

OBJECTIVE: The purpose of this pilot study was to test the feasibility of delivering the mobile mindfulness-based stress reduction for breast cancer (mMBSR(BC)) program using an iPad and to evaluate its impact on symptom improvement. METHODS: A single group, pre-posttest design was implemented among female stages 0-III breast cancer survivors (BCS) who completed treatment. Data were collected at baseline and week 6 on measures of psychological and physical symptoms and quality of life. The mMBSR(BC) program is a standardized, stress-reducing intervention that combines sitting and walking meditation, body scan, and yoga and is designed to deliver weekly 2-hour sessions for 6 weeks using an iPad. RESULTS: The mean age of the 15 enrolled BCS was 57 years; one participant was non-Hispanic black, and 14 were non-Hispanic white. Of the 13 who completed the study, there were significant improvements from baseline to 6 weeks post-mMBSR(BC) in psychological and physical symptoms of depression, state anxiety, stress, fear of recurrence, sleep quality, fatigue, and quality of life (P's < .05). Effect sizes for improvements of multiple symptoms ranged from medium to large. CONCLUSIONS: These results provide preliminary support that the mMBSR(BC) program may be feasible and acceptable, showing a clinical impact on decreasing psychological and physical symptoms. This mobile-based program offers a delivery of a standardized MBSR(BC) intervention to BCS that is convenient for their own schedule while decreasing symptom burden in the survivorship phase after treatment for breast cancer.

Exergame Grading Scheme: Concept Development and Preliminary Psychometric Evaluations in Cancer Survivors.

The challenge of using exergames to promote physical activity among cancer survivors lies in the selection of the exergames that match their fitness level. There is a need for a standardized grading scheme by which to judge an exergame's capacity to address specific physical fitness attributes with different levels of physical engagement. The study aimed to develop an Exergame Grading Scheme and preliminarily evaluate its psychometric properties. Fourteen (14) items were created from the human movement and exergame literature. The content validity index (CVI) was rated by content experts with two consecutive rounds (N = 5 and N = 3 independently). The interrater reliability (IRR) was determined by two raters who used the Exergame Grading Scheme to determine the grading score of the five exergames performed by two cancer survivors (N = 10). Each item had a score of 1 for item-level CVI and 1 for k. For IRR, 9 items had rho values of 1, 1 item had 0.93, and 4 items had between 0.80 and 0.89. This valid and reliable Exergame Grading Scheme makes it possible to develop a personalized physical activity program using any type of exergame or fitness mobile application in rehabilitation practice to meet the needs of cancer survivors.

Development and Evaluation of a Lung Cancer Screening Decision Aid.

Lung cancer is the second most common cancer; however, it often is not diagnosed until the advanced stages. Early-stage lung cancer is curable, but screening tools are not usually implemented in practice because of a lack of provider awareness. A lung cancer screening decision aid may increase screening use and, ultimately, reduce lung cancer deaths.


Issues Faced by Family Caregivers of Hospice Patients with Head and Neck Cancers.

PURPOSE: The purpose of this study was to explore issues reported by caregivers of Head and Neck cancer (HNC) patients newly admitted to hospice homecare. METHODS: 26 caregivers providing hospice homecare to patients with HNC were induded. Caregiver depressive symptoms, social support and perceived health data were analyzed. RESULTS: The caregivers reported few depressive symptoms, good perceived social support, and good perceived health; however, there was large variation in the group with some individuals having significant problems. DISCUSSION: Caregivers appeared to be doing well physically, emotionally and socially, but baseline data were used, so follow-up data are needed. Further research is warranted. CONCLUSIONS: Family caregivers also are affected by the experience of cancer and may have depressive symptoms needing assessment and management. Hospice patients with HNC have a variety of symptoms specific to their disease and treatment that need assessment and management by their family caregivers. Caregivers of HNC patients in hospice and palliative care need and deserve attention from hospice providers as they care for patients.

Predictors of stage of adoption for colorectal cancer screening among African American primary care patients.

BACKGROUND: Compared with other racial groups, African Americans have the highest colorectal cancer (CRC) incidence and mortality rates coupled with lower screening rates. OBJECTIVE: Our study examined the predictors of stage of adoption for fecal occult blood testing (FOBT) and colonoscopy among African American primary care patients who were nonadherent to published screening guidelines. METHODS: Baseline data (N = 815) in a randomized clinical trial were analyzed. Participants were categorized into precontemplation, contemplation, and preparation stages for FOBT and colonoscopy. Predictor variables were demographics, clinical variables, CRC health beliefs and knowledge, and social support. Hierarchical modeling was to identify significant predictors of stage of adoption. RESULTS: Older, male, Veterans Affairs participants and those with higher perceived self-efficacy, family/friend encouragement, and a provider recommendation had higher odds of being at a more advanced stage of adoption for FOBT. Patients with a history of cancer and higher perceived barriers had higher odds of being at an earlier stage of adoption for FOBT. Predictors of more advanced stage of adoption for colonoscopy included higher perceived benefits, higher perceived self-efficacy, family/friend encouragement, and a provider recommendation for colonoscopy. Higher income (>30 000 vs <15 000) was predictive of earlier stage of adoption for colonoscopy. CONCLUSIONS: Enhancing self-efficacy, encouragement from family and friends, and provider recommendations are important components of interventions to promote CRC screening. IMPLICATIONS FOR PRACTICE: Nurses can use knowledge of the characteristics associated with stage of adoption to educate and motivate their African American primary care patients to complete CRC screening tests.

Shoulder pain, functional status, and health-related quality of life after head and neck cancer surgery.

Head and neck cancer (HNC) patients experience treatment-related complications that may interfere with health-related quality of life (HRQOL). The purpose of this study was to describe the symptom experience (shoulder pain) and functional status factors that are related to global and domain-specific HRQOL at one month after HNC surgery. In this exploratory study, we examined 29 patients. The outcome variables included global HRQOL as well as physical, functional, emotional, and social well-being. Symptom experience and functional status factors were the independent variables. In the symptom experience variables, shoulder pain distress was negatively associated with physical well-being (R (2) = 0.24). Among the functional status variables, eating impairment was negatively related to global HRQOL (R (2) = 0.18) and physical well-being (R (2) = 0.21). Speaking impairment and impaired body image explained a large amount of the variance in functional well-being (R (2) = 0.45). This study provided initial results regarding symptom experience and functional status factors related to poor HRQOL in the early postoperative period for HNC patients.

Computer-delivered tailored intervention improves colon cancer screening knowledge and health beliefs of African-Americans.

We conducted a randomized controlled trial among African-American patients attending a primary-care provider visit to compare efficacy of a computer-delivered tailored intervention to increase colorectal cancer (CRC) screening (n = 273) with non-tailored print material-an American Cancer Society brochure on CRC screening (n = 283). Health Belief Model constructs were used to develop tailored messages and examined as outcomes. Analysis of covariance models were used to compare changes between CRC knowledge and health belief scores at baseline and 1 week post-intervention. At 1 week, patients who received the computer-delivered tailored intervention had greater changes in CRC knowledge scores (P < 0.001), perceived CRC risk scores (P = 0.005), FOBT barriers scores (P = 0.034) and colonoscopy benefit scores (P < 0.001). Findings show that computer-delivered tailored interventions are an effective adjunct to the clinical encounter that can improve knowledge and health beliefs about CRC screening, necessary precursors to behavior change.

Predictors of cancer-related pain improvement over time.

OBJECTIVE: To determine the predictors of pain improvement among patients being treated for cancer-related pain over 12 months. METHODS: A secondary analysis of the telephone care Indiana Cancer Pain and Depression trial was performed. Patients (n = 274) were interviewed at baseline and after 1, 3, 6, and 12 months. Pain improvement outcomes included both a continuous measure (Brief Pain Inventory score) and a categorical measure (pain improved versus pain not improved). Predictor variables included change in depression, age, sex, race, marital status, socioeconomic disadvantage, medical comorbidity, type of cancer, and phase of cancer. Multivariable repeated measures were conducted, adjusting for intervention group assignment, baseline pain severity, and time in months since baseline assessment. RESULTS: Factors significantly predicting both continuous and categorical pain improvement included participating in the intervention group (ß = -0.92, p < .001, odds ratio [OR] = 2.53, 95% confidence interval [CI] = 1.65-3.89), greater improvement in depression (ß = -0.31, p = .003, OR = 1.84, 95% CI = 1.35-2.51), higher socioeconomic status (Socioeconomic Disadvantage index; ß = 0.25, p = .034; OR = 0.73, 95% CI = 0.56-0.94), and fewer comorbid conditions (ß = 0.20, p = .002; OR = 0.84, 95% CI = 0.73-0.96). Patients with more severe pain at baseline or with recurrent or progressive cancer were less likely to experience continuous or categorical pain improvement, respectively. CONCLUSIONS: Effective management of depression and comorbid conditions along with improvement of social services could be critical components of a comprehensive pain management. Patients with more severe pain or with recurrent or progressive cancers may require closer monitoring and adequate treatment of pain. Trial Registration clinicaltrials.gov Identifier: NCT00313573.
