Item Acceptability and Feasibility of a Meaning-Based Intervention for Patients With Advanced Cancer and Their Spouses A Pilot Study(Sage, 2016) Wagner, Christina D.; Johns, Shelley; Brown, Linda F.; Hanna, Nasser; Bigatti, Silvia M.; Department of Social and Behavioral Sciences, Richard M. Fairbanks School of Public HealthBackground: Constructing meaning in cancer leads to improved psychosocial outcomes for patients and survivors. Aim: We tested the feasibility and preliminary efficacy of a meaning-based intervention for couples. Design: The single-arm pilot study tested a 4-session, tailored, activities-based couple’s intervention. Setting/Participants: Twelve adults with incurable cancer and their partners participated either in a university office or at the couple’s home. Results: The study showed good feasibility. One of the two patients depressed at baseline was no longer depressed at postintervention. Patients’ threat appraisals decreased and transcendence increased. In partners, depression, anxiety, and challenge appraisal decreased; threat and secondary appraisals and peace with illness increased. Conclusions: Our findings suggest feasibility and efficacy, and further research and continued evaluation of this intervention are warranted.Item Acceptance and commitment therapy for breast cancer survivors with fear of cancer recurrence: A 3-arm pilot randomized controlled trial(Wiley, 2020) Johns, Shelley A.; Stutz, Patrick V.; Talib, Tasneem; Cohee, Andrea A.; Beck-Coon, Kathleen A.; Brown, Linda F.; Wilhelm, Laura R.; Monaham, Patrick O.; LaPradd, Michelle L.; Champion, Victoria L.; Miller, Kathy D.; Giesler, R. BrianBackground Fear of cancer recurrence (FCR) has a profound negative impact on quality of life (QOL) for many cancer survivors. Breast cancer survivors (BCS) are particularly vulnerable, with up to 70% reporting clinically significant FCR. To the authors' knowledge, evidence-based interventions for managing FCR are limited. Acceptance and commitment therapy (ACT) promotes psychological flexibility in managing life's stressors. The current study examined the feasibility and preliminary efficacy of group-based ACT for FCR in BCS. Methods Post-treatment BCS (91 patients with stage I-III disease) with clinical FCR randomly were assigned to ACT (6 weekly 2-hour group sessions), survivorship education (SE; 6 weekly 2-hour group sessions), or enhanced usual care (EUC; one 30-minute group coaching session with survivorship readings). FCR severity (primary outcome) and avoidant coping, anxiety, post-traumatic stress, depression, QOL, and other FCR-related variables (secondary outcomes) were assessed at baseline (T1), after the intervention (T2), 1 month after the intervention (T3), and 6 months after the intervention (T4) using intent-to-treat analysis. Results Satisfactory recruitment (43.8%) and retention (94.5%) rates demonstrated feasibility. Although each arm demonstrated within-group reductions in FCR severity over time, only ACT produced significant reductions at each time point compared with baseline, with between-group differences at T4 substantially favoring ACT over SE (Cohen d for effect sizes, 0.80; P < .001) and EUC (Cohen d, 0.61; P < .01). For 10 of 12 secondary outcomes, only ACT produced significant within-group reductions across all time points. By T4, significant moderate to large between-group comparisons favored ACT over SE and EUC with regard to avoidant coping, anxiety, depression, QOL, and FCR-related psychological distress. Conclusions Group-based ACT is a feasible and promising treatment for FCR and associated outcomes in BCS that warrants testing in larger, fully powered trials.Item Depression and Cancer-Related Fatigue: A Cross-Lagged Panel Analysis of Causal Effects(2012-07-03) Brown, Linda F.; Bigatti, Silvia M.; Kroenke, Kurt; Rand, Kevin L.; Stewart, Jesse C.Fatigue is one of the most common and debilitating symptoms reported by cancer patients, yet it is infrequently diagnosed or treated. Relatively little is understood about its etiology in the cancer context. Recently, as researchers have begun to focus attention on cancer-related fatigue (CRF), depression has emerged as its strongest correlate. Few longitudinal studies have been done, however, to determine whether causal influences between the two symptoms exist. The aim of the current study was to determine whether depression has a causal influence on CRF and whether reciprocal effects exist. The study used a single-group cohort design of longitudinal data from a randomized controlled trial (N = 405) of an intervention for pain and depression in a heterogeneous sample of cancer patients. To be eligible, participants met criteria for clinically significant pain or depression. A hypothesis that depression would influence change in fatigue after 3 months was tested using latent variable cross-lagged panel analysis, a structural equation modeling technique. A second hypothesis was that fatigue would also influence change in depression over time but at a lesser magnitude. Depression and fatigue were strongly correlated in the sample (i.e., baseline correlation of latent variables was 0.72). Although the model showed good fit to the data, χ2 (66, N = 329) = 88.16, p = 0.04, SRMR = 0.030, RMSEA = 0.032, and CFI = 1, neither cross-lagged structural path was significant. The findings suggest that depression had no causal influence on changes in fatigue in this sample, and fatigue did not influence change in depression. The clinical implication is that depression treatment may not be helpful as a treatment for CRF and therefore interventions specifically targeting fatigue may be needed. Future research should include additional waves of data and larger sample sizes.Item Longitudinal relationships between fatigue and depression in cancer patients with depression and/or pain(American Psychological Association, 2013-12) Brown, Linda F.; Rand, Kevin L.; Bigatti, Silvia M.; Stewart, Jesse C.; Theobald, Dale E.; Wu, Jingwei; Kroenke, Kurt; Social and Behavioral Sciences, Richard M. Fairbanks School of Public HealthOBJECTIVE: Fatigue is one of the most common and debilitating symptoms reported by cancer patients, yet relatively little is understood about its etiology. Recently, as researchers have begun to focus attention on cancer-related fatigue (CRF), depression has emerged as its strongest correlate. Few longitudinal studies, however, have examined directionality of the relationship between the two symptoms. Our aim was to evaluate the directionality of the association between depression and CRF. METHOD: The study used a single-group cohort design of longitudinal data (N = 329) from a randomized controlled trial of an intervention for pain and depression in a heterogeneous sample of cancer patients. Participants met criteria for clinically significant pain and/or depression. Our hypothesis that depression would predict change in fatigue over 3 months was tested using latent variable cross-lagged panel analysis. RESULTS: Depressive symptoms and fatigue were strongly correlated in the sample (baseline correlation of latent variables = 0.71). Although the model showed good fit to the data, χ(2) (66, N = 329) = 88.16, p = .04, SRMR = 0.030, RMSEA = 0.032, and CFI = 1.00, neither structural path linking depression and fatigue was significant, suggesting neither symptom preceded and predicted the other. CONCLUSIONS: Our findings did not support hypotheses regarding the directionality of the relationship between depressive symptoms and fatigue. The clinical implication is that depression-specific treatments may not be sufficient to treat CRF and that instead, interventions specifically targeting fatigue are needed.Item Mindfulness to enhance quality of life and support advance care planning: a pilot randomized controlled trial for adults with advanced cancer and their family caregivers(Springer Nature, 2024-09-28) Mosher, Catherine E.; Beck-Coon, Kathleen A.; Wu, Wei; Lewson, Ashley B.; Stutz, Patrick V.; Brown, Linda F.; Tang, Qing; Helft, Paul R.; Levoy, Kristin; Hickman, Susan E.; Johns, Shelley A.; Psychology, School of ScienceBackground: Patients with advanced cancer and family caregivers often use avoidant coping strategies, such as delaying advance care planning discussions, which contribute to deterioration in their quality of life. Mindfulness-based interventions have shown promise in improving quality of life in this population but have rarely been applied to advance care planning. This pilot trial examined the preliminary efficacy of a group-based Mindfulness to Enhance Quality of Life and Support Advance Care Planning (MEANING) intervention for patient-caregiver dyads coping with advanced cancer. Primary outcomes were patient and caregiver quality of life or well-being, and secondary outcomes included patient advanced care planning engagement (self-efficacy and readiness) and other psychological and symptom outcomes. Methods: In this pilot trial, dyads coping with advanced cancer were recruited from five oncology clinics in the midwestern U.S. and randomized to six weekly group sessions of a mindfulness intervention (n = 33 dyads) or usual care (n = 22 dyads). Outcomes were assessed via surveys at baseline, post-intervention, and 1 month post-intervention. All available data were included in the multilevel models assessing intervention efficacy. Results: Patients in the MEANING condition experienced significant increases in existential well-being and self-efficacy for advance care planning across follow-ups, whereas usual care patients did not. Other group differences in outcomes were not statistically significant. These outcomes included other facets of patient well-being, caregiver quality of life, patient readiness for advance care planning, caregiver burden, and patient and caregiver depressive symptoms, anxiety, sleep disturbance, cognitive avoidance, and peaceful acceptance of cancer. However, only MEANING patients showed moderate increases in psychological well-being across follow-ups, and MEANING caregivers showed moderate increases in quality of life at 1-month follow-up. Certain psychological outcomes, such as caregiver burden at 1-month follow-up, also showed moderate improvement in the MEANING condition. Patients in both conditions reported small to moderate increases in readiness to engage in advance care planning. Conclusions: A mindfulness-based intervention showed promise in improving quality-of-life and advance care planning outcomes in patients and caregivers coping with advanced cancer and warrants further testing.Item Psychological Processes and Symptom Outcomes in Mindfulness-Based Stress Reduction for Cancer Survivors: A Pilot Study(Springer, 2020) Chinh, Kelly; Mosher, Catherine E.; Brown, Linda F.; Beck-Coon, Kathleen A.; Kroenke, Kurt; Johns, Shelley A.; Psychology, School of ScienceObjectives Growing evidence supports the efficacy of mindfulness-based interventions for symptoms in cancer survivors. Identifying theory-based psychological processes underlying their effects on symptoms would inform research to enhance their efficacy and cost-effectiveness. We conducted secondary analyses examining the effect of mindfulness-based stress reduction (MBSR) for cancer-related fatigue on mindfulness facets, self-compassion, and psychological inflexibility. We also examined whether changes in these processes were associated with the symptom outcomes of fatigue interference, sleep disturbance, and emotional distress. Methods Thirty-five persistently fatigued cancer survivors (94% female, 77% breast cancer survivors) were randomized to either MBSR for cancer-related fatigue or a waitlist control (WC) condition. Self-report measures were administered at pre-intervention, post-intervention, and 1-month follow-up. Then the WC group received MBSR and completed a post-intervention follow-up. Results Linear mixed modeling analyses of the first three time points showed steady increases over time for certain mindfulness facets (observing, acting with awareness, and nonjudging) and self-compassion in favor of the MBSR group. When analyzing pre- and post-intervention data across study conditions, none of the psychological processes predicted change in fatigue interference. However, increased nonjudging was associated with decreased sleep disturbance (β = −.39, p = 0.003), and increased acting with awareness was associated with decreased emotional distress (β = − 0.36, p = 0.003). Self-compassion did not predict change in symptom outcomes. Conclusions Results point to specific psychological processes that may be targeted to maximize the efficacy of future MBSR interventions for cancer survivors.Item Randomized controlled pilot study of mindfulness-based stress reduction for persistently fatigued cancer survivors(Wiley, 2015-08) Johns, Shelley A.; Brown, Linda F.; Monahan, Patrick O.; Tong, Yan; Kroenke, Kurt; Beck-Coon, Kathleen; IU School of NursingOBJECTIVE: Cancer-related fatigue (CRF) is one of the most common, persistent, and disabling symptoms associated with cancer and its treatment. Evidence-based treatments that are acceptable to patients are critically needed. This study examined the efficacy of mindfulness-based stress reduction (MBSR) for CRF and related symptoms. METHOD: A sample of 35 cancer survivors with clinically significant CRF was randomly assigned to a 7-week MBSR-based intervention or wait-list control group. The intervention group received training in mindfulness meditation, yoga, and self-regulatory responses to stress. Fatigue interference (primary outcome) and a variety of secondary outcomes (e.g., fatigue severity, vitality, disability, depression, anxiety, and sleep disturbance) were assessed at baseline, post-intervention, and 1-month follow-up. Bonferroni correction was employed to account for multiple comparisons. Controls received the intervention after the 1-month follow-up. Participants in both groups were followed for 6 months after completing their respective MBSR courses to assess maintenance of effects. RESULTS: Compared to controls, the MBSR group reported large post-intervention reductions as assessed by effect sizes (d) in the primary outcome, fatigue interference (d = -1.43, p < 0.001), along with fatigue severity (d = -1.55, p < 0.001), vitality (d = 1.29, p < 0.001), depression (d = -1.30, p < 0.001), and sleep disturbance (d = -0.74, p = 0.001). Results were maintained or strengthened at 1-month follow-up, the point at which significant improvements in disability (d = -1.22, p < 0.002) and anxiety (d = -0.98, p = 0.002) occurred. Improvements in all outcomes were maintained 6 months after completing the course. MBSR adherence was high, with 90% attendance across groups and high rates of participant-reported home practice of mindfulness. CONCLUSIONS: Mindfulness-based stress reduction is a promising treatment for CRF and associated symptoms.Item Randomized Controlled Pilot Trial of Mindfulness-Based Stress Reduction Compared to Psychoeducational Support for Persistently Fatigued Breast and Colorectal Cancer Survivors(Springer, 2016-10) Johns, Shelley A.; Brown, Linda F.; Beck-Coon, Kathleen; Talib, Tasneem L.; Monahan, Patrick O.; Giesler, R. Brian; Tong, Yan; Wilhelm, Laura; Carpenter, Janet S.; Von Ah, Diane; Wagner, Christina D.; de Groot, Mary; Schmidt, Karen; Monceski, Diane; Danh, Marie; Alyea, Jennifer M.; Miller, Kathy D.; Kroenke, Kurt; Medicine, School of MedicinePurpose Cancer-related fatigue (CRF) is a disruptive symptom for many survivors. Despite promising evidence for efficacy of Mindfulness-Based Stress Reduction (MBSR) in reducing CRF, no trials comparing it to an active comparator for fatigued survivors have been published. The purpose of this trial was to compare MBSR to psychoeducation for CRF and associated symptoms. Methods Breast (n=60) and colorectal (n=11) cancer survivors (stage 0–III) with clinically significant CRF after completing chemotherapy and/or radiation therapy an average of 28 months prior to enrollment were randomized to MBSR or psychoeducation/support groups (PES). MBSR focused on mindfulness training; PES focused on CRF self-management. Outcomes included CRF interference (primary), CRF severity and global improvement, vitality, depression, anxiety, sleep disturbance, and pain. Outcomes were assessed at baseline (T1), post-intervention (T2), and 6-month follow-up (T3) using intent-to-treat analysis. Results Between-group differences in CRF interference were not significant at any time point; however, there was a trend favoring MBSR (d=−0.46, p=0.073) at T2. MBSR participants reported significantly greater improvement in vitality (d=0.53, p=0.003) and were more likely to report CRF as moderately-to-completely improved compared to the PES group (χ2 (1)=4.1765, p=0.041) at T2. MBSR participants also reported significantly greater reductions in pain at T2 (d=0.53, p=0.014). In addition, both MBSR and PES produced moderate-to-large and significant within-group improvements in all fatigue outcomes, depression, anxiety, and sleep at T2 and T3 compared to T1. Conclusion MBSR and PES appear efficacious for CRF and related symptoms. Larger trials including a usual care arm are warranted.Item Randomized Controlled Pilot Trial of Mindfulness-Based Stress Reduction for Breast and Colorectal Cancer Survivors: Effects on Cancer-Related Cognitive Impairment(Springer, 2016-06) Johns, Shelley A.; Von Ah, Diane; Brown, Linda F.; Beck-Coon, Kathleen; Talib, Tasneem L.; Alyea, Jennifer M.; Monahan, Patrick O.; Tong, Yan; Wilhelm, Laura; Giesler, R. Brian; Department of Medicine, Indiana University School of MedicinePurpose Cancer-related cognitive impairment (CRCI) is a common, fatigue-related symptom that disrupts cancer survivors’ quality of life. Few interventions for CRCI exist. As part of a randomized pilot study targeting cancer-related fatigue, the effects of mindfulness-based stress reduction (MBSR) on survivors’ cognitive outcomes were investigated. Methods Breast and colorectal cancer survivors (n = 71) with moderate-to-severe fatigue were randomized to MBSR (n = 35) or a fatigue education and support (ES; n = 36) condition. The Attentional Function Index (AFI) and the Stroop test were used to assess survivors’ cognitive function at baseline (T1), after the 8-week intervention period (T2), and 6 months later (T3) using intent-to-treat analysis. Mediation analyses were performed to explore mechanisms of intervention effects on cognitive functioning. Results MBSR participants reported significantly greater improvement on the AFI total score compared to ES participants at T2 (d = 0.83, p = 0.001) and T3 (d = 0.55, p = 0.021). MBSR also significantly outperformed ES on most AFI subscales, although both groups improved over time. MBSR produced greater Stroop accuracy rates relative to ES at T2 (r = 0.340, p = 0.005) and T3 (r = 0.280, p = 0.030), with improved accuracy over time only for the MBSR group. There were no significant differences in Stroop reaction time between groups. Improvements in mindfulness mediated the effect of group (e.g., MBSR vs. ES) on AFI total score at T2 and T3. Conclusions Additional randomized trials with more comprehensive cognitive measures are warranted to definitively assess the efficacy of MBSR for CRCI. Implications for Cancer Survivors This pilot study has important implications for all cancer survivors as it is the first published trial to show that MBSR offers robust and durable improvements in CRCI.
