Reflective Engagement With a Digital Physical Activity Intervention Among People Living With and Beyond Breast Cancer: Mixed Methods Study.

BACKGROUND: People living with and beyond breast cancer can face internal barriers to physical activity (eg, fatigue and pain). Digital interventions that promote psychological acceptance and motivation may help this population navigate these barriers. The degree to which individuals (1) adhere to intervention protocols and (2) reflect on and internalize intervention content may predict intervention efficacy. OBJECTIVE: The objective of this study was to characterize the nature of reflective processes brought about by an 8-week acceptance- and mindfulness-based physical activity intervention for insufficiently active survivors of breast cancer (n=75). Furthermore, we explored the potential utility of a metric of reflective processes for predicting study outcomes. METHODS: Of the intervention's 8 weekly modules, 7 (88%) included an item that asked participants to reflect on what they found to be most useful. Two coders conducted directed content analysis on participants' written responses. They assessed each comment's depth of reflection using an existing framework (ranging from 0 to 4, with 0=simple description and 4=fundamental change with consideration of social and ethical issues). The coders identified themes within the various levels of reflection. We fit multiple linear regression models to evaluate whether participants' (1) intervention adherence (ie, number of modules completed) and (2) the mean level of the depth of reflection predicted study outcomes. RESULTS: Participants were aged on average 57.2 (SD 11.2) years, mostly non-Hispanic White (58/75, 77%), and mostly overweight or obese (54/75, 72%). Of the 407 responses to the item prompting personal reflection, 70 (17.2%) were rated as reflection level 0 (ie, description), 247 (60.7%) were level 1 (ie, reflective description), 74 (18.2%) were level 2 (ie, dialogic reflection), 14 (3.4%) were level 3 (ie, transformative reflection), and 2 (0.5%) were level 4 (ie, critical reflection). Lower levels of reflection were characterized by the acquisition of knowledge or expressing intentions. Higher levels were characterized by personal insight, commentary on behavior change processes, and a change of perspective. Intervention adherence was associated with increases in self-reported weekly bouts of muscle-strengthening exercise (B=0.26, SE 0.12, 95% CI 0.02-0.50) and decreases in sleep disturbance (B=-1.04, SE 0.50, 95% CI -0.06 to -2.02). The mean level of reflection was associated with increases in psychological acceptance (B=3.42, SE 1.70, 95% CI 0.09-6.75) and motivation for physical activity (ie, integrated regulation: B=0.55, SE 0.25, 95% CI 0.06-1.04). CONCLUSIONS: We identified a useful method for understanding the reflective processes that can occur during digital behavior change interventions serving people living with and beyond breast cancer. Intervention adherence and the depth of reflection each predicted changes in study outcomes. Deeper reflection on intervention content was associated with beneficial changes in the determinants of sustained behavior change. More research is needed to investigate the relations among digital behavior change intervention use, psychological processes, and intervention efficacy.

Psychosocial Interventions for Pain Management in Breast Cancer Survivors: A RE-AIM Evaluation.

Psychosocial interventions for breast-cancer-related pain are effective, yet over 45% of survivors continue to struggle with this often-chronic side effect. This study evaluated multilevel indicators that can influence successful translation of interventions into clinical practice. The Reach, Effectiveness, Adoption, Implementation, and Maintenance (RE-AIM) framework was applied to evaluate reporting of individual and setting/staff-level intervention indicators. A systematic search and multi-step screening process identified 31 randomized controlled trials for psychosocial interventions for breast cancer-related pain. Average reporting of indicators for individual-level dimensions (Reach and Effectiveness) were 65.2% and 62.3%, respectively. Comparatively, indicators for setting/staff-level dimensions were reported at a lower average frequency (Implementation, 46.8%; Adoption, 15.2%; Maintenance, 7.7%). Low reporting of setting/staff-level dimensions suggests gaps in the sustained implementation of psychosocial interventions. Implementation science methods and frameworks could improve trial design and accelerate the translation of psychosocial interventions for breast cancer-related pain into clinical practice.

Guided imagery for treatment (GIFT): protocol of a pilot trial of guided imagery versus treatment as usual to address radiotherapy-related distress in head and neck cancer.

BACKGROUND: Cancers of the head and neck region are associated with high symptom burden and elevated levels of psychological distress. Radiotherapy (RT) is a common treatment for patients with head and neck cancer (HNC) that is associated with psychological distress related to the immobilizing nature of the treatment, frequency of treatment delivery, and side effects. Guided imagery is a relaxation technique that is beneficial in reducing psychological distress in patients with other cancer diagnoses but has not been studied in this patient population. The purpose of this study is to evaluate the feasibility and acceptability of a brief guided imagery intervention (guided imagery for treatment, GIFT) to reduce RT-related anxiety and depression in patients with HNC relative to treatment as usual (TAU). METHODS: Patients with HNC planning to receive RT will be recruited to participate in a randomized controlled trial evaluating a brief, two-session guided imagery intervention (GIFT) relative to TAU alone. Primary aims include acceptability and feasibility evaluated through quantitative and qualitative methods. Measures of anxiety and depression, symptom burden, health-related quality of life, and anxiolytic medication use will be collected at baseline, during treatment, and at 1-month follow-up. DISCUSSION: There are no published interventions of guided imagery for anxiety and depression in patients with HNC despite its efficacy in other populations of patients with cancer. This proposed project evaluates the feasibility and acceptability of an intervention that has the potential to reduce psychological distress in a vulnerable population. Additionally, we will preliminarily examine the impact of behavioral intervention on psychological distress and the use of anxiolytic medication, a novel area of study.

The Acceptability of an Electronically Delivered Acceptance- and Mindfulness-Based Physical Activity Intervention for Survivors of Breast Cancer: One-Group Pretest-Posttest Design.

BACKGROUND: Survivors of breast cancer can face internal barriers to physical activity, such as uncertainty and frustration stemming from physical limitations, decreased physical functioning, fatigue, and pain. Interventions that draw from the principles of Acceptance and Commitment Therapy (ACT) may help survivors of breast cancer overcome some of the internal barriers associated with physical activity. OBJECTIVE: The primary aim of this study was to investigate the acceptability of an electronically delivered physical activity intervention for survivors of breast cancer, centered on ACT processes. METHODS: This study used a 1-group pretest-posttest design. We recruited 80 insufficiently active female survivors of breast cancer using a web-based recruitment strategy. The 8-week intervention consisted of weekly modules that featured didactic lessons and experiential exercises targeting key ACT processes in the context of physical activity promotion (namely, values, committed action, acceptance, defusion, and contacting the present moment). We determined intervention acceptability according to study retention (≥70%), adherence rates (≥75% of the participants completing ≥50% of the modules), and posttest survey scores reflecting the perceived ease of use, perceived usefulness, and interest and enjoyment of the intervention (≥5 on a 7-point Likert-type scale). We also evaluated changes in self-reported aerobic and muscle strengthening-physical activity, physical activity acceptance, physical activity regulation, and health-related outcomes. RESULTS: The retention rate (61/80, 76%), adherence rate (60/80, 75%), average perceived ease of use (6.17, SD 1.17), perceived usefulness (5.59, SD 1.40), and interest and enjoyment scores (5.43, SD 1.40) met the acceptability criteria. Participants increased their self-reported aerobic physical activity (Cohen d=1.04), muscle strengthening-physical activity (Cohen d=1.02), physical activity acceptance (cognitive acceptance: Cohen d=0.35; behavioral commitment: Cohen d=0.51), physical activity regulation (identified regulation: Cohen d=0.37; integrated regulation: Cohen d=0.66), increased their ability to participate in social roles and activities (Cohen d=0.18), and reported less fatigue (Cohen d=0.33) and sleep disturbance (Cohen d=0.53). CONCLUSIONS: Electronically delivered acceptance- and mindfulness-based interventions may be useful for promoting physical activity in survivors of breast cancer. Further research is needed to refine these approaches and evaluate their effectiveness.

Acceptance- and mindfulness-based techniques for physical activity promotion in breast cancer survivors: a qualitative study.

PURPOSE: The purpose of this study was to develop and characterize the relevance and potential utility of an electronically delivered acceptance- and mindfulness-based approaches to physical activity promotion for insufficiently active breast cancer survivors. METHODS: The acceptance- and mindfulness-based physical activity intervention was delivered to participants electronically over the course of 4-8 weeks. It consisted of didactic videos, experiential exercises, and workbook-type activities that targeted principles from acceptance and commitment therapy (ACT). We conducted semi-structured, in-depth interviews with participants after they completed the intervention. Three coders conducted qualitative data analysis on interview transcripts to identify overarching themes and subthemes. RESULTS: We recruited 30 participants. Of those, 16 engaged in an individual interview. The mean age of the sample was 58.4 years (SD = 13.8). The sample was relatively well educated (50.0% college graduates) and mostly overweight or obese (58.8%). We identified two overarching themes from interviews. They were centered on (1) internal and external barriers to physical activity adherence and (2) the utility of targeting core ACT processes (acceptance and defusion, mindfulness, and values clarification) for physical activity promotion. CONCLUSION: Intervention content was perceived to be acceptable, relevant, and to fulfill important needs related to healthy living. Findings suggest that this approach to physical activity promotion can be delivered effectively online. Electronically delivered acceptance- and mindfulness-based approaches hold promise for helping insufficiently active breast cancer survivors increase physical activity.

Psychotropic medications in oncology.

CONTEXT: Psychological distress is common in patients with cancer, and oncology providers are often tasked with utilizing psychotropic medications to treat such symptoms. OBJECTIVE: This study aims to characterize how oncology providers prescribe psychotropic medications and to assess their comfort level with prescribing these medications. METHODS: A cross-sectional survey was sent to oncology medical doctors, nurse practitioners, and physician assistants who prescribe psychotropic medications to patients with cancer at a large academic medical center in the Mountain West. The survey included questions regarding provider subspecialty, degree, comfort with prescribing psychotropic medications, and factors that informed their prescribing. RESULTS: Oncology providers (n = 65) reported equal proportions of comfort and discomfort with prescribing psychotropic medications. The medication class with the most prescribers was benzodiazepines, with 89.2% (n = 58) of the respondents prescribing those medications. The least prescribed category was mood stabilizers, with 4.6% (n = 3) prescribing this category. Prescribers identified that barriers to their comfort included difficulty connecting patients to follow-up care with mental health professionals and inadequate mental health education for providers. Providers responded that continuing mental health education and increasing patient access to mental health resources would increase their prescribing comfort. CONCLUSION: Providers reported equal parts comfort and discomfort with prescribing psychotropic medications; avenues to increase comfort should involve focused mental health education during formal training and continued education throughout their oncology careers. A clinical pathway for prescribing psychotropic medications with resources to connect patients to long-term mental health care may also increase prescribing comfort.

Suicidal ideation in patients with cancer: A systematic review of prevalence, risk factors, intervention and assessment.

OBJECTIVES: Suicidal ideation (SI) underlies risk of death by suicide. It is well established that patients with cancer are at increased risk of death by suicide. Therefore, understanding SI in patients with cancer is critically important. The goal of this systematic review was to investigate the prevalence, risk factors, intervention, and assessment of SI in patients with cancer. METHODS: This systematic review was registered with the PROSPERO database (CRD42018115405) and was guided by the PRISMA statement. We searched Medline, PsycInfo, Embase, CINAHL, the Cochrane Database of Systematic Reviews, and Cochrane Central. Two reviewers independently screened abstracts and assessed for quality assurance using a revised Newcastle-Ottawa Scale. RESULTS: We identified 439 studies to screen for eligibility. Eligible studies included adults with cancer diagnoses and listed SI as an outcome. Ultimately, 44 studies were included in the analyses. Prevalence of SI ranged greatly from 0.7% to 46.3%. Single items drawn from validated measures were the most frequent method of assessing SI (n = 20, 45.5%); additional methods included validated measures and psychological interviews. Commonly identified risk factors for SI included age, sex, and disease/treatment-related characteristics, as well as psychological constructs including depression, anxiety, hopelessness, existential distress, and social support. SIGNIFICANCE OF RESULTS: Assessment of SI in patients with cancer is the concern of researchers worldwide. Prevalence of SI varied with study population and was likely influenced by the method of assessment. Psychological distress consistently predicted SI. Increasing awareness of demographic, clinical, and psychological associations is critical for risk assessment and intervention development.

Chronic pain, health-related quality of life, and employment in working-age cancer survivors.

PURPOSE: This study estimated the prevalence of cancer-related pain in working-age cancer survivors (age 25-64 years) and evaluated differences in demographic and clinical variables in those with and without pain. We also investigated the impact of cancer-related pain on health-related quality of life (HRQoL) and employment outcomes in this population. METHODS: We used cross-sectional data from the 2016 Behavioral Risk Factor Surveillance System (BRFSS). Analyses were conducted with a sample of 1702 cancer survivors who completed treatment. All analyses were conducted using procedures to account for the complex sampling design of the BRFSS. RESULTS: Nearly 17% (95% CI [13.94-19.58]) of working-age cancer survivors reported experiencing cancer-related pain. Among those who experienced pain, the majority were female, white, non-Hispanic, married/partnered, and non-employed, with breast as the most common cancer disease site. Those with cancer-related pain experienced more physically unhealthy days (adjusted rate ratio [aRR] 1.63, 95% CI [1.16-2.28]), mentally unhealthy days (aRR 1.52, 95% CI [1.02-2.26]), and activity interference (aRR 2.15, 95% CI [1.53-3.02]). Cancer-related pain decreased the odds of being employed, but only in female survivors (adjusted odds ratio 0.34, 95% CI [0.22-0.54]). CONCLUSION: Cancer-related chronic pain is a prevalent, long-term condition that is negatively associated with HRQoL and employment in working-age cancer survivors. IMPLICATIONS FOR CANCER SURVIVORS: Clinical interventions targeting chronic pain may improve HRQoL in working-age cancer survivors and employment outcomes, particularly in women.

Changing multiple health behaviors in cancer survivors: smoking and exercise.

Research regarding cross-behavioral relationships between the cognitive mechanisms motivating health behavior change is lacking for cancer survivors. This study investigated these relationships to inform the development of multiple health behavior change (MHBC) interventions for this at-risk population. Eligible participants included cancer survivors attending an intake appointment for smoking cessation services. This cross-sectional survey study assessed participants' self-efficacy and motivation (stage of change) for smoking cessation and exercise, as well as self-reported health behaviors. Analyses evaluated cross-behavioral associations between cognitive mechanisms and their relationships with smoking and exercise behaviors. Seventy-six participants completed the survey questionnaire. The correlation between self-efficacy scores for smoking cessation and exercise was statistically significant (r = .45, 95% CI [.09, .67]), as were correlations between self-efficacy and reported levels of exercise ((r = .44, 95% CI [.20, .65]) strenuous); ((r = .36, 95% CI [.12, .59]) moderate), exercise self-efficacy and smoking behavior (r = -.27, 95% CI [-.46, -.05]), and smoking self-efficacy and smoking behavior (r = -0.41, 95% CI [-.61, -.18]). For cancer survivors, associations between exercise self-efficacy and smoking cessation self-efficacy may offer an opportunity to leverage MHBC; specifically, this positive association may facilitate exercise intervention in survivors seeking smoking cessation services..

An Ecological Momentary Assessment Study Investigating Self-efficacy and Outcome Expectancy as Mediators of Affective and Physiological Responses and Exercise Among Endometrial Cancer Survivors.

BACKGROUND: Previous studies have shown affective and physiological states in response to exercise as predictors of daily exercise, yet little is known about the mechanism underlying such effects. PURPOSE: To examine the mediating effects of self-efficacy and outcome expectancy on the relationships between affective and physiological responses to exercise and subsequent exercise levels in endometrial cancer survivors. METHODS: Ecological momentary assessment (EMA) surveys were delivered up to eight 5- to 7-day periods over 6 months. Participants (n = 100) rated their affective and physiological states before and after each exercise session (predictors) and recorded their self-efficacy and outcome expectancy each morning (mediators). Exercise (outcome) was based on self-reported EMA surveys and accelerometer measures. A 1-1-1 multilevel mediation model was used to disaggregate the within-subject (WS) and between-subject (BS) effects. RESULTS: At the WS level, a more positive affective state after exercise was associated with higher self-efficacy and positive outcome expectation the next day, which in turn was associated with higher subsequent exercise levels (ps < .05). At the BS level, participants who typically had more positive affective and experienced less intense physiological sensation after exercise had higher average self-efficacy, which was associated with higher average exercise levels (ps < .05). CONCLUSIONS: In endometrial cancer survivors, affective experience after exercise, daily self-efficacy and positive outcome expectation help explain the day-to-day differences in exercise levels within-person. Findings from this study highlight potentials for behavioral interventions that target affective experience after exercise and daily behavioral cognitions to promote physical activity in cancer survivors' everyday lives.

Predictors of enrollment in individual- and couple-based lifestyle intervention trials for cancer survivors.

PURPOSE: To utilize data from lifestyle intervention pilot studies for cancer survivors to elucidate demographic, disease-related, and health behavior factors that might predict enrollment in this type of research. Additionally, factors were differentially compared based on intervention design (i.e., individual versus couple-based). METHODS: Secondary data analysis was conducted regarding predictors of enrollment into lifestyle intervention studies, including Healthy Moves Weight Loss (individual participants, screened n = 89, enrolled n = 30) and Healthy Moves Couples (survivors and their partners, screened n = 197, enrolled n = 23). Due to small sample sizes, common in pilot studies, random forest analyses were used to maximize information yielded by the data. RESULTS: Results identified numerous important predictors of enrollment in individual and couple-based lifestyle interventions. Percent energy from fat and physical activity minutes were identified as important predictors for both recruitment methods. Age, cancer site, and marital status were important predictors of enrollment in the individual-based intervention. Weight, fiber consumption, and disease-related symptom severity and interference were important predictors of enrollment in the couple-based intervention. CONCLUSION: Although there was some overlap in predictors for enrollment between studies, many differential predictors were identified between individual versus couple-based study designs for lifestyle intervention in cancer survivors. Future lifestyle intervention studies for cancer survivors may benefit from targeting different predictors of enrollment based on study design to optimize recruitment. Additionally, understanding predictors may allow certain barriers to enrollment (i.e., symptom burden) to be directly addressed, making lifestyle intervention research more feasible and acceptable to difficult-to-recruit survivors.

Evaluation of the effects of a clinically implemented exercise program on physical fitness, fatigue, and depression in cancer survivors.

PURPOSE: Despite national recommendations, exercise programs are still not clinically implemented as standard of care for cancer survivors. This investigation examined the effects of a clinically implemented and personalized exercise program on physical fitness, fatigue, and depression in a diverse population of cancer survivors. The association of various participant characteristics on program performance was also examined. METHODS: Data were collected from 170 cancer survivors who had participated in a clinical exercise program. Any cancer type was included and survivors were either undergoing medical treatment or had completed treatment (< 6 months prior to program initiation). Baseline and post program measures of estimated VO2peak, grip strength, fatigue, and depression were compared in survivors who completed the program follow-up. Multiple regressions were performed to investigate the association of age, gender, body mass index (BMI), and medical treatment status on baseline and change scores in outcome measures, as well as program adherence. RESULTS: All measures improved in participants who completed the program (p < 0.01). Age, gender, and BMI were associated with baseline measures of estimated VO2peak and grip strength (p < 0.01), and age was inversely associated with baseline fatigue (p = 0.02). Only BMI was inversely associated with change in estimated VO2peak (p < 0.01). No participant characteristics or baseline measures were predictive of program adherence (p > 0.05). CONCLUSION: This investigation provides evidence that a personalized, clinical exercise program can be effective at improving physical fitness, fatigue, and depression in a diverse population of cancer survivors.

Psychometric Study of the Pain Drawing.

PURPOSE: The objectives of the study were to (1) assess the extent to which interrater reliability of pain drawing location and dispersion scoring methods are similar across pain disciplines in a sample of patients with cancer treatment-induced neuropathic pain (N = 56) and (2) investigate indicators of validity of the pain drawing in this unique sample. METHODS: Patients undergoing cancer therapy completed the Brief Pain Inventory Body Map, the MD Anderson Symptom Inventory, and the McGill Pain Questionnaire. RESULTS: Intraclass correlation coefficients among medical and psychology professionals ranged from .93-.99. Correlations between pain drawing score and symptom burden severity ranged from .29-.39; correlations between pain drawing score and symptom burden interference ranged from .28-.34. Patients who endorsed pain in the hands and feet more often described their pain as electric, numb, and shooting than patients without pain in the hands and feet. They also endorsed significantly more descriptors of neuropathic pain. CONCLUSIONS: Results suggest a similar understanding among members of a multidisciplinary pain team as to the location and dispersion of pain as represented by patients' pain drawings. In addition, pain drawing scores were related to symptom burden severity and interference and descriptors of neuropathic pain in expected ways.

Comparison of Internet and Telephone Interventions for Weight Loss Among Cancer Survivors: Randomized Controlled Trial and Feasibility Study.

BACKGROUND: Weight loss interventions have been successfully delivered via several modalities, but recent research has focused on more disseminable and sustainable means such as telephone- or Internet-based platforms. OBJECTIVE: The aim of this study was to compare an Internet-delivered weight loss intervention to a comparable telephone-delivered weight loss intervention. METHODS: This randomized pilot study examined the effects of 6-month telephone- and Internet-delivered social cognitive theory-based weight loss interventions among 37 cancer survivors. Measures of body composition, physical activity, diet, and physical performance were the outcomes of interest. RESULTS: Participants in the telephone intervention (n=13) showed greater decreases in waist circumference (-0.75 cm for telephone vs -0.09 cm for Internet, P=.03) than the Internet condition (n=24), and several other outcomes trended in the same direction. Measures of engagement (eg, number of telephone sessions completed and number of log-ins) suggest differences between groups which may account for the difference in outcomes. CONCLUSIONS: Cancer survivors in the telephone group evidenced better health outcomes than the Internet group. Group differences may be due to higher engagement in the telephone group. Incorporating a telephone-based component into existing weight loss programs for cancer survivors may help enhance the reach of the intervention while minimizing costs. More research is needed on how to combine Internet and telephone weight loss intervention components so as to maximize engagement and outcomes.

Disease burden and pain in obese cancer patients with chemotherapy-induced peripheral neuropathy.

PURPOSE: Chemotherapy-induced peripheral neuropathy (CIPN) and obesity are prevalent in cancer survivors and decrease quality of life; however, the impact of the co-occurrence of these conditions has garnered little attention. This study investigated differences between obese and non-obese cancer survivors with CIPN and predictors of symptom burden and pain. METHODS: Patients with CIPN were administered the MD Anderson Symptom Inventory and a modified version of pain descriptors from the McGill Pain Inventory. Independent t tests assessed group differences between obese and non-obese survivors, and linear regression analyses explored predictors of patient outcomes. RESULTS: Results indicated a significant difference in symptom severity scores for obese (M = 32.89, SD = 25.53) versus non-obese (M = 19.35, SD = 16.08) patients (t(37.86) = -2.49, p = .02). Significant differences were also found for a total number of pain descriptors endorsed by obese (M = 4.21, SD = 3.45) versus non-obese (M = 2.42, SD = 2.69) participants (t(74) = -2.53, p = .01). Obesity was a significant predictor of symptom severity and total pain descriptors endorsed. Other significant predictors included age and months since treatment. CONCLUSIONS: Cancer survivors with CIPN and co-occurring obesity may be more at risk for decreased quality of life through increased symptom severity and pain compared to non-obese survivors. This paper identified risk factors, including obesity, age, and months since treatment, that can be clinically identified for monitoring distress in CIPN patients. Future research should focus on the longitudinal relationship between obesity and CIPN, and robust interventions to address the multifaceted issues faced by cancer survivors.
