Predictors of fatigue improvement in multimodal, multimodal-aerobic and aerobic exercise intervention studies in breast cancer survivors with cancer-related fatigue
2025
Cancer-related fatigue (CRF) is common among breast cancer (BC) survivors. In addition to aerobic training, psychoeducation, sleep education/restriction, and mindfulness-based therapies are shown to reduce CRF. This study investigates the predictive effect of hygiogenetic and salutogenetic concepts, such as autonomic regulation (aR), self-regulation (SRS) and internal coherence (ICS) along with sleep quality (PSQI) and quality of life (EORTC QLQ C30, including cognitive, emotional and physical functioning) on the success of CRF therapies. Two studies are analyzed: a pilot (CRF-1) with 36 BC patients and a follow-up study (CRF2) with 126 patients either randomized or assigned to therapy by preference. All parameters were assessed at baseline and 10 weeks post-intervention (T1), and in CRF-2 also six months later (T2), and after four years (T3). Multiple linear regression models were applied. Trait aR and ICS are shown to be significant predictors of CRF when all timepoints of the CRF-2 study are included (β
Trait aR
= −0.170, df = 70,
p
< 0.001; β
ICS

CF
= −0.073, df = 70,
p
< 0.05). Using data from two studies with multimodal, aerobic and combined CRF treatments, this study highlights Trait aR and ICS at baseline as long-term predictors of CRF even four years after intervention. A stable autonomic regulation including rest/activity regulation and internal coherence are predictors for therapy response of a multimodal, combination or aerobic treatment in breast cancer survivors with CRF.

Four-year follow-up on fatigue and sleep quality of a three-armed partly randomized controlled study in breast cancer survivors with cancer-related fatigue
2023
Cancer-related fatigue (CRF) is a frequent long-term symptom in non-metastasized breast cancer patients (BC). This 4-year follow-up intended to compare the long-term effects of a 10-week multimodal therapy (MT: sleep education, psychoeducation, eurythmy- and painting therapy) and combination therapy [CT: MT plus aerobic training (AT)] to AT-control. BC-patients were randomized or allocated by preference to three arms in a comprehensive cohort study. Primary outcome was a composite score including Pittsburgh Sleep Quality Index (PSQI) and Cancer Fatigue Scale (CFS-D), captured at baseline, after 10 weeks of intervention (T1), 6 months later (T2), and after 4 years (T3). We exploratively tested for superiority of MT and CT versus AT after 4 years (T3) based on the statistical model of the main analysis. Of 126 (65 randomized) BC-patients included, 105 started treatments and 79 were re-assessed for long-term effects (T3). MT and CT were superior over AT after 4 years regarding PSQI/CFS-D and PSQI sum-score, respectively (all
p
< 0.05), but not for CFS-D. The multimodal and combination treatment for breast cancer patients with CRF indicates sustainable long-term superiority over aerobic training for the outcomes sleep quality and combined sleep quality/fatigue. A confirmative randomized controlled trial is warranted.

The Anthroposophic Artistic Movement Assessment for Eurythmy Therapy (AART-ASSESS-EuMove). A validation study
2023
Eurythmy Therapy (ET) is a mindfulness oriented therapy developed in the context of anthroposophic medicine. Despite commonly used in practice, it remains unclear whether active participation (Inner Correspondence) during ET can be observed in eurythmy gestures (EGest). So far, no validated peer-report instrument to evaluate EGest exists.
To validate an 83-item ET peer-report scale, a nested study on a sample of n = 82 breast cancer survivors with cancer-related fatigue was conducted. EGest were evaluated twice, at baseline and at 10-week follow-up, by peer-reports from two separate therapists. Interrater-reliability (IRR) was estimated by Cohen’s weighted kappa (κw) across all items. Additionally, reliability-(RA) and principal component analyses (PCA) were conducted. Patients completed two self-report scales: Satisfaction with ET (SET) and Inner Correspondence with the Movement Therapy (ICPH).
IRR was greater than or equal (κw ≥ 0.25) for 41 items (49.3%) with a mean weighted kappa of κ̅w = 0.40 (SD = 0.17, range = 0.25–0.85). RA resulted in the exclusion of 25 items with insufficient item-total correlations < 0.40. A PCA with 16 items revealed 3 subscales: 1. Mindfulness in Movement (8 items), 2. Motor Skills (5 items), 3. Walking Pattern (3items) explaining 63.86% of total variance. Internal consistency (Cronbach’s alpha) was high for the sum score with α = 0.89 and for the subscales with α = 0.88, 0.86 and 0.84 respectively. Significant small to moderate subscale correlations were found ranging from r = 0.29–0.63 (all p < 0.01). Mindfulness in Movement correlated with Inner Correspondence (r = 0.32) and with Satisfaction with ET (r = - 0.25, both p < 0.05).
The new AART-ASSESS-EuMove is the first consistent and reliable peer-report instrument to evaluate EGest. It shows associations between peer-reported Mindful Movement and patients’ self-reported ICPH and SET.

Reliability and first validity of the inner correspondence questionnaire for painting therapy (ICPTh) in a sample of breast cancer patients
2019
•Art therapy as mindfulness-oriented intervention is commonly used in anthroposophic medicine.•Inner Correspondence with Painting Therapy (ICPTh) is a 22-item self-report instrument with robust reliability and validity.•A factor analysis revealed an unambiguous four-factor solution.•Inner Correspondence with Painting Therapy (ICPTh) as new concept could function as possible mediator for clinical outcome.
Objectives Art therapy (ArT) such as mindfulness-oriented painting therapy is increasingly used in psychosomatic, oncological integrative and rehabilitative medicine. Though it remains unknown how ArT works, we hypothesize that an engaged participation with painting (‘Inner-Correspondence’) contributes to improved symptom scores. In the context of a comprehensive cohort study for breast cancer survivors with cancer-related fatigue, we developed a patient-reported outcome measure to assess ‘Inner Correspondence’ with painting therapy and conducted a first validation study.
Design A 24-item questionnaire on ‘Inner Correspondence’ (ICPTh) was administered after ten weeks of intervention and at six month followup together with concurrent scales (Inner Correspondence and Peaceful Harmony, Cancer Fatigue Scale, Hospital Anxiety and Depression Scale, Internal Coherence Scale). Statistical assessment included reliability- and factor analyses.
Results A total of n = 68 BC (mean age, 58.2 years, SD = 8.7) participated in the preliminary validation study. Exploratory factor analysis revealed a robust 22-item scale with an unambiguous four-factor solution explaining 78% of total variance and the following subsales: 1) therapy congruence and relaxation (11 items), 2) inner development and mood (6 items), 3) artistic skill (3 items) and 4) task congruence (2 items). The 22-item ICPTh yielded high reliability (Cronbach’s alpha = .966, item-total correlation = .497 – .883, test-retest reliability = .888).
Conclusions We present a reliable instrument to measure ‘Inner Correspondence’ with painting therapy. Due to the small sample size and sample selection further validation studies are indicated.

Impact of autonomic and self-regulation on cancer-related fatigue and distress in breast cancer patients – a prospective observational study
2014
Purpose
Cancer-related fatigue (CRF) has a major impact on the quality of life in breast cancer patients (BC). So far, only a few prospective studies have investigated the effect of adaptive salutogenic mechanisms on CRF. The aim of our study was to evaluate the possible prospective influence of autonomic Regulation (aR) and self-regulation (SR) on CRF and distress in long-term survivors.
Methods
95 BC and 80 healthy female controls (C) had been included in the observational study between 2000 and 2001 and completed the questionnaires on aR, SR and Hospital Anxiety and Depression Scale (HADS). Of these, 62 BC, and 58 C participated in the re-evaluation 6.6 years later: 16 participants were deceased (14 BC and 2 C). During follow-up, participants were requested to answer questions involving (Cancer Fatigue Scales) CFS-D, aR, SR and HADS. Multiple regression analysis was used to evaluate the influence of aR, SR, age, Charlson co-morbidity-index and diagnosis on CFS-D and HADS, and to select further potentially relevant factors.
Results
High aR values showed significant effects, namely inverse relationships with CFS-D, cognitive fatigue, anxiety and depression. SR showed a reduced influence on anxiety and depression (all p < 0.05).
Conclusions
Autonomic regulation might have an independent, reductive influence on global fatigue, cognitive fatigue and – together with self-regulation – it seems to have a protective influence on anxiety and depression. The connection between these parameters is still unclear and awaits further evaluation.
Implication for Cancer Survivors
AR seems to be a prognostic factor in breast cancer survivors, capable of reducing cancer-related fatigue and self-regulation distress as well. Further research is necessary in order to show how aR can be improved by therapeutic interventions.

Background
Cancer-related fatigue (CRF) and insomnia are major complaints in breast cancer survivors (BC). Aerobic training (AT), the standard therapy for CRF in BC, shows only minor to moderate treatment effects. Other evidence-based treatments include cognitive behavioral therapy, e.g., sleep education/restriction (SE) and mindfulness-based therapies. We investigated the effectiveness of a 10-week multimodal program (MT) consisting of SE, psycho-education, eurythmy- and painting-therapy, administered separately or in combination with AT (CT) and compared both arms to AT alone.
Methods
In a pragmatic comprehensive cohort study BC with chronic CRF were allocated randomly or by patient preference to (a) MT, (b) CT (MT + AT) or (c) AT alone. Primary endpoint was a composite score of the Pittsburgh Sleep Quality Index and the Cancer Fatigue Scale after 10 weeks of intervention (T1); a second endpoint was a follow-up assessment 6 months later (T2). The primary hypothesis stated superiority of CT and non-inferiority of MT vs. AT at T1. A closed testing procedure preserved the global α-level. The intention-to-treat analysis included propensity scores for the mode of allocation and for the preferred treatment, respectively.
Results
Altogether 126 BC were recruited: 65 were randomized and 61 allocated by preference; 105 started the intervention. Socio-demographic parameters were generally balanced at baseline. Non-inferiority of MT to AT at T1 was confirmed (
p
< 0.05), yet the confirmative analysis stopped as it was not possible to confirm superiority of CT vs. AT (
p
= 0.119). In consecutive exploratory analyses MT and CT were superior to AT at T1 and T2 (MT) or T2 alone (CT), respectively.
Conclusions
The multimodal CRF-therapy was found to be confirmatively non-inferior to standard therapy and even yielded exploratively sustained superiority. A randomized controlled trial including a larger sample size and a longer follow-up to evaluate multimodal CRF-therapy is highly warranted.

Context: Cancer-related fatigue (CRF) is one of the most burdensome symptoms in breast cancer survivors (BCSs), accompanied by reduced health-related quality of life (HRQOL). Objectives: This study investigated the influence of a multimodal therapy (MT; psychoeducation, eurythmy therapy, painting therapy, and sleep education/restriction), or a combination therapy (CT; MT plus aerobic training [AT]) on HRQOL in BCS with chronic CRF in comparison with AT alone. Methods: One hundred and twenty-six BCSs with CRF were included in a pragmatic comprehensive cohort study and allocated either per randomization or by preference to MT, CT, or AT. The EORTC QLQ-C30 core questionnaire was used to measure HRQOL. All analyses on HRQOL parameters were done in an explorative intention. Results: Patients were assigned to MT (n = 44), CT (n = 54), or AT (n = 28). CT was significantly superior to AT after 10 weeks of intervention (T1) in improving physical function. MT was found to have significant superiority over AT at T1 and T2 for physical functioning, emotional functioning, insomnia, and financial problems as well as role functioning, cognitive, social functioning, and fatigue 6 months later (T2). Conclusion: A multimodal approach appears to be a suitable concept for BCS with chronic CRF. A confirmatory study with larger samples should demonstrate the superiority of MT and adapted CT in HRQOL compared with the current treatment AT found in these explorative analyses.

Background: Recent studies have proved the relevance of salutogenetic variables for fatigue management in breast cancer survivors with cancer-related fatigue (CRF). This comprehensive cohort design study is the first to examine the impact of 2 multimodal therapies, multimodal therapy (MT) and combined therapy (CT), compared with standard aerobic training (AT) on salutogenetic variables (self-regulation and internal coherence) and distress in breast cancer survivors with CRF. Methods: A total of 105 patients started the therapies and n = 84 completed the Self-regulation Scale, the Internal Coherence Scale, the Cancer Fatigue Scale, and the Hospital Anxiety and Depression Scale at baseline, 10 weeks after treatment (T1) and n = 81 after 6 months (T2). Patient satisfaction and qualitative feedback regarding therapy quality was assessed at T1. A general linear model including allocation type, therapy arm (MT/CT/AT), and bias-adjusting propensity scores tested the superiority of both multimodal therapies versus AT for all questionnaires at T1 and T2. Results: MT and CT were superior to AT to improve self-regulation and patients’ satisfaction at T1. Additionally, CT showed superiority for self-regulation at T2 (all P < .05). Compared with AT, internal coherence was significantly higher for patients in the MT arms at T2, respectively (all P < .01). Pearson’s correlations between self-regulation, internal coherence, and CRF improved from baseline to T2 (Mean r = −0.60). Qualitative feedback confirmed patients’ benefits in several health-related categories. Conclusions: Self-regulation and internal coherence are manipulable variables with relevant CRF associations. They can be positively affected by multimodal therapies. Alongside patients’ satisfaction and qualitative feedback they help refine treatment.
