The role of daily adjustment disorder, depression and anxiety symptoms for the physical activity of cardiac patients.

BACKGROUND: Physical activity (PA) is crucial in the treatment of cardiac disease. There is a high prevalence of stress-response and affective disorders among cardiac patients, which might be negatively associated with their PA. This study aimed at investigating daily differential associations of International Classification of Diseases (ICD)-11 adjustment disorder, depression and anxiety symptoms with PA and sedentary behaviour (SB) during and right after inpatient cardiac rehabilitation. METHODS: The sample included N = 129 inpatients in cardiac rehabilitation, Mage = 62.2, s.d.age = 11.3, 84.5% male, n = 2845 days. Adjustment disorder, depression and anxiety symptoms were measured daily during the last 7 days of rehabilitation and for 3 weeks after discharge. Moderate-to-vigorous PA (MVPA), light PA (LPA) and SB were measured with an accelerometer. Bayesian lagged multilevel regressions including all three symptoms to obtain their unique effects were conducted. RESULTS: On days with higher adjustment disorder symptoms than usual, patients engaged in less MVPA, and more SB. Patients with overall higher depression symptoms engaged in less MVPA, less LPA and more SB. On days with higher depression symptoms than usual, there was less MVPA and LPA, and more SB. Patients with higher anxiety symptoms engaged in more LPA and less SB. CONCLUSIONS: Results highlight the necessity to screen for and treat adjustment disorder and depression symptoms during cardiac rehabilitation.

Predicting physical activity following cardiac rehabilitation: A longitudinal observational study.

PURPOSE: The adoption of a healthy lifestyle is crucial for patients with established cardiac diseases. However, many patients do not engage in regular physical activity in their everyday life. RESEARCH METHOD: The present study applied the health action process approach (HAPA) in an intensive longitudinal research design (n = 3,354 daily surveys) investigating intention towards physical activity and objectively measured physical activity in 137 cardiac patients (Mage = 62.1 years) during and after inpatient rehabilitation across 28 days. Self-reported HAPA variables were measured daily in online questionnaires at the end of each day. Theory-driven hypotheses were tested using linear multilevel models. RESULTS: One-third of the sample did not reach the recommended physical activity levels in the first weeks after discharge from rehabilitation. Results are mostly in line with the motivational HAPA phase at both levels of analysis; outcome expectations and self-efficacy were positively associated with intentions. Results for the volitional phase were partly in line with the HAPA. Daily deviations in previous-day planning and concurrent action control were positively associated with physical activity during and after cardiac rehabilitation. CONCLUSION: The results of this study partly speak towards the HAPA in predicting physical activity in cardiac patients, thereby replicating prior research. The HAPA framework offers guidance for motivating and empowering cardiac patients to be more active in their everyday life. (PsycInfo Database Record (c) 2023 APA, all rights reserved).

Social support, distress and well-being in individuals experiencing Long-COVID: a cross-sectional survey study.

OBJECTIVES: Increasingly attention of the COVID-19 pandemic is directed towards its long-term effects, also known as Long-COVID. So far, Long-COVID was examined mainly from a medical perspective, leaving psychosocial effects of Long-COVID understudied. The present study advances the current literature by examining social support in the context of Long-COVID. The study not only examines received support reported by individuals with Long-COVID, but also provided support reported by relatives of individuals with Long-COVID. DESIGN: Cross-sectional study. SETTING: The study was conducted from June to October 2021 in Austria, Germany and the German-speaking part of Switzerland. PARTICIPANTS: We examined 256 individuals with Long-COVID (MAge=45.05 years, 90.2% women) and 50 relatives of individuals with Long-COVID (MAge=48.34 years, 66.1% female) in two separate online surveys, assessing social support, well-being and distress. PRIMARY OUTCOME MEASURES: Primary outcomes were positive and negative affect, anxiety and depressive symptoms and perceived stress. RESULTS: For individuals with Long-COVID, receiving emotional support was related to higher well-being (positive affect: b=0.29, p<0.01; negative affect: b=-0.31, p<0.05) and less distress (anxiety: b=-1.45, p<0.01; depressive symptoms: b=-1.04, p<0.05; perceived stress: b=-0.21, p<0.05) but no effects emerged for receiving practical support. For relatives of individuals with Long-COVID, providing emotional support was only related to lower depressive symptoms (b=-2.57, p<0.05). Again, provided practical support was unrelated to the outcomes considered. CONCLUSIONS: Emotional support is likely to play an important role in well-being and distress of patients and relatives, whereas practical support does not seem to make a difference. Future research should clarify under what conditions different kinds of support unfold their positive effects on well-being and distress in the context of Long-COVID.

Social Stigma, Mental Health, Stress, and Health-Related Quality of Life in People with Long COVID.

A considerable amount of people who have been infected with SARS-CoV-2 experience ongoing symptoms, a condition termed long COVID. This study examined nuanced experiences of social stigma in people with long COVID and their associations with perceived stress, depressive symptoms, anxiety, and mental and physical health-related quality of life (hrqol). A total of N = 253 participants with long COVID symptoms (mean age = 45.49, SD = 12.03; n = 224, 88.5% women) completed a cross-sectional online survey on overall social stigma and the subfacets enacted and perceived external stigma, disclosure concerns, and internalized stigma. Data were analysed using multiple regression and controlling for overall burden of consequences of long COVID, overall burden of symptoms of long COVID, and outcome-specific confounders. In line with our preregistered hypotheses, total social stigma was related to more perceived stress, more depressive symptoms, higher anxiety, and lower mental hrqol, but-in contrast to our hypothesis-it was unrelated to physical hrqol after controlling for confounders. The three subscales of social stigma resulted in differential associations with the outcomes. Social stigma experiences go hand in hand with worse mental health in people with long COVID. Future studies should examine potential protective factors to buffer the effects of social stigma on people's well-being.

Implementation of a Novel Medication Regimen Following Cardiac Rehabilitation: an Application of the Health Action Process Approach.

BACKGROUND: Medication adherence is an indispensable prerequisite for the long-term management of many chronic diseases. However, published literature suggests that non-adherence is widely prevalent. Health behavior change theories can help understand the underlying processes and allow the accumulation of knowledge in the field. The present study applied the health action process approach (HAPA) in an intensive longitudinal research design to investigate medication adherence in patients after discharge from inpatient cardiac rehabilitation. METHOD: In total, n = 139 patients (84.9% male, Mage = 62.2 years) completed n = 2,699 daily diaries in the 22 days following discharge from inpatient cardiac rehabilitation. Patients' intentions to take medication and predictors were assessed in daily end-of-day questionnaires. Adherence to medication was measured subjectively (self-report) and objectively. Multilevel modeling was applied to disentangle the between- and within-person level. RESULTS: Higher levels of risk awareness and self-efficacy were positively associated with intentions to take medication at both levels of analysis. Contrary to theoretical assumptions, positive outcome expectations were not associated with intention, neither between- nor within-person. In contrast to published literature, patients showed very high medication adherence (95.2% self-report, 92.2% objectively). CONCLUSION: In line with the theoretical assumptions, the results showed that risk awareness and self-efficacy are promising modifiable factors that could be targeted to motivate patients to take medication as prescribed. Daily measurements revealed that patients took their medication as prescribed; thus, future studies should make every effort to recruit patients vulnerable to non-adherence to avoid ceiling effects.

Differential associations of emotional and physical domains of the MacNew Heart with changes in 6-min walking test.

AIMS: Cardiac rehabilitation (CR), a key component of secondary prevention in cardiac patients, contributes fundamentally to improved cardiovascular health outcomes. Health-related quality of life (HRQOL) represents a widely employed outcome measure in CR, yet, its predictive properties on exercise capacity change during CR are poorly understood. Aim of this study was to examine the association between baseline HRQOL and its subdomains on improvement of exercise capacity during CR. METHODS: Study participants were 13,717 inpatients of six Swiss CR clinics from 2012 to 2018. We measured HRQOL at admission to CR with the MacNew Heart (MNH) questionnaire and exercise capacity at admission and discharge using the six minutes walking test (6MWT). Following factorial analyses, we performed univariate and multivariate analyses to test the predictive properties of baseline global HRQOL and its domains for improvement in exercise capacity, adjusting for demographic and clinical characteristics. RESULTS: Mean improvement in 6MWT was 114 m (SD = 90), achieved after 17.4 days (SD = 5.5). Lower emotional HRQOL (b = 7.85, p = < .001, 95% CI [- 5.67, 10.03]) and higher physical HRQOL (b = - 5.23, p < .001, 95% CI [- 6.56, - 3.90]) were associated with less improvement in the 6MWT. Global MNH and social HRQOL showed no association with exercise capacity improvement. CONCLUSION: Patients entering CR with low emotional and high physical HRQOL are at risk for a lower gain in exercise capacity during CR. Global MNH alone does not provide a reliable assessment of HRQOL; thus a focus on specific domains of HRQOL is needed.

Depression and anxiety in cardiac rehabilitation: differential associations with changes in exercise capacity and quality of life.

BACKGROUND: Cardiac rehabilitation (CR) has been successful in improving exercise capacity (EC) and quality of life (QoL). However, depression and anxiety are highly prevalent among cardiac patients and might represent risk factors for rehabilitation outcomes. The aim of this study was to investigate the role of depression and anxiety as possible independent risk factors for CR outcomes. METHODS: The study applied a pre-post-design. The sample comprised N = 3'434 cardiac disease patients taking part in a Swiss inpatient CR center. Variables measured at the beginning (T1) and end of rehabilitation (T2) included depression and anxiety (HADS), EC, and QoL (MacNew). A path analysis was conducted. RESULTS: Depression at T1 had a significant negative relationship with improvements in EC and in all aspects of QoL during rehabilitation. Anxiety at T1 was positively related to improvements in EC and in emotional and physical QoL. Improvements in depression during CR were positively related with improvements in all outcomes. Improvements in anxiety showed no significant association with the outcomes. CONCLUSION: Depression and anxiety should be screened for during CR. Depression should be treated due to the negative association found with rehabilitation outcomes. Underlying mechanisms of the positive association of anxiety with rehabilitation outcomes need further investigation.

Physical activity after cardiac rehabilitation: Explicit and implicit attitudinal components and ambivalence.

OBJECTIVE: Physical activity is crucial in the treatment of cardiac disease. In addition to sociocognitive theories of behavior change, attitudinal ambivalence and nonconscious factors have also been demonstrated to predict physical activity. We propose an extension to the theory of planned behavior with a dual-systems approach including explicit and implicit attitudes, and different types of attitudinal ambivalence as moderators to predict the physical activity of patients after discharge from inpatient cardiac rehabilitation. METHOD: The sample comprised N = 111 cardiac patients who provided daily diary reports of intention, cognitive, affective, and implicit attitudes for 21 days after discharge (86% male, Mage = 62, SDage = 11, n = 2,017 days). Daily moderate-to-vigorous (MVPA) and light (LPA) physical activity were measured using accelerometers. Five types of ambivalence were calculated. Analyses included Bayesian multilevel modeling. RESULTS: Patients with more positive affective attitudes and more positive implicit attitudes had a higher intention. Higher ambivalence weakened the affective attitudes-intention relationship. On days with more positive implicit attitudes than usual, intention was lower, but only when ambivalence was low. Patients with higher ambivalence engaged in less MVPA. On days with extremely low ambivalence, implicit attitudes were negatively associated with tomorrow's MVPA. Patients with more positive affective attitudes engaged in more LPA, but only when their ambivalence was very low. On days with higher ambivalence than usual, the next day's LPA was shorter. However, another type of ambivalence showed the opposite effect. CONCLUSIONS: The results emphasize the importance of affective and implicit attitudes and ambivalence for the physical activity of cardiac patients.

Metastatic Breast Cancer as a Chronic Disease: Evidence-Based Data on a Theoretical Concept.

BACKGROUND: We challenge the concept of metastatic breast cancer (MBC) as a chronic disease. METHODS: We analyzed an unselected cohort of 367 patients who were diagnosed with MBC over a 22-year period (1990-2011). RESULTS: In order to create a "chronic disease subgroup", we separated those patients from the entire cohort in whom systemic therapy was not applied after the diagnosis of MBC (n = 53; 14.4%). Three hundred fourteen patients (85.6%) comprised the "chronic disease subgroup". The vast majority of those patients (89.8%) died of progressive disease after a median metastatic disease survival (MDS) of 25 months. Twenty patients (6.4%) died of non-MBC-related causes (MDS 38.5 months). Approximately 1 in 4 patients (26.8%) died within the first year after the MBC diagnosis. The 3- and 5-year MDS rates were 35.4 and 16.2%, respectively. Only 12 patients (3.8%) were exceptional survivors (MDS >10 years). CONCLUSION: The term "chronic disease" might be appropriate in selected MBC cases, bringing MBC into alignment with "classical" chronic diseases such as diabetes and hypertension. However, most cases display fundamental differences with regard to temporal progression and above all the case fatality rate. More than 90% of patients in the "chronic disease subgroup" died of the disease with a MDS of 2-3 years (even those who underwent systemic palliative therapies). Doctors and patients might understand the term "chronic disease" differently. The term must be used sparingly and explained carefully in order to create a common level of communication based on a shared understanding which avoids awakening false hopes and fostering misleading expectations.

Improvements in exercise capacity of older adults during cardiac rehabilitation.

AIMS: Cardiac rehabilitation plays a vital role in secondary prevention of cardiovascular patients. Female sex and higher age, however, are associated with non-referral to cardiac rehabilitation. Improving exercise capacity during cardiac rehabilitation is essential to reduce morbidity and mortality risks. The objective of this study was to closely examine the beneficial changes in exercise capacity of older patients of both sexes during cardiac rehabilitation and to identify the most important predictors of the change in exercise capacity. METHOD: A sample of 13,612 patients (mean age = 69.10 ± 11.8 years, 63.7% men, 19% > 80 years) was analysed. Data were prospectively assessed from 2012-2018 in six Swiss in-patient cardiovascular rehabilitation clinics. Improvement in exercise capacity measured with the six-minute walking test represents the outcome variable. Univariate and multivariate analyses, as well as the random forest method were used to estimate variable importance. RESULTS: Mean improvement in the six-minute walking test was 113.5 ± 90.5 m (men = 118.7 ± 110.0; women = 104.4 ± 93.0, Cohen's d = 0.16). The presence of heart failure, diabetes mellitus and psychiatric diagnoses was related to reduced but nonetheless clinically relevant six-minute walking test improvement. Random forest analysis suggests that baseline exercise capacity, age, time in rehabilitation and heart failure were the most important predictors for improvement in exercise capacity. Clinically relevant improvements in exercise capacity (>45 m) were also present into old age (85 years) and for both sexes. CONCLUSION: As indicated by these results, efforts need to be increased to refer eligible patients to structured rehabilitation programmes, irrespective of patients' age and sex.

Noncompliance with palliative systemic therapy in patients with distant metastatic breast cancer: a blind spot for oncologists?

PURPOSE: The goal of our study was to provide a general overview of noncompliance with palliative systemic therapy in distant metastatic breast cancer (MBC). METHODS: We analyzed an unselected cohort of 339 patients who were diagnosed with MBC over a 22-year period (1990-2011, age restriction: ≥ 85 years old). RESULTS: Forty patients (11.8%) rejected the offered or recommended systemic therapy (age distribution of this noncompliance subgroup: ≤60 years at MBC diagnosis: 7.9%; 60-70 years: 13.2%; > 70 years: 15.6%). The rate of noncompliance was equally distributed over time (1990-1999: 12.2% vs. 2000-2011: 11.5%, p = 0.87). Compared to patients who had received palliative antineoplastic systemic therapy, those who remained untreated were significantly older (70 vs. 61 years, p = 0.015), had shorter metastatic disease survival (2 vs. 27 months, p < 0.001), had more often an aggressive tumor subtype (hormone-receptor negative carcinomas: 48.7% vs. 22.2%, p < 0.001), and had more often secondary MBC (95.0% vs. 73.6%, p = 0.001). CONCLUSIONS: Although the high rate of noncompliance in the subgroup of elderly patients was not unexpected, it is noticeable that even in the subgroup of patients who were younger than 60 years, approximately 8% also rejected any systemic therapy before a MBC-related death occurred This group of younger women rarely had any relevant comorbidities, were potential candidates for chemotherapy and knowingly declined the therapy options. Such patients are never or seldom seen by oncologists in their daily practice and therefore play a minor role in their personal perception of disease. Nevertheless, these under-reported cases make up a significant proportion of MBC.

Challenges and solutions for N-of-1 design studies in health psychology.

Theories of behaviour change and health behaviour change interventions are most often evaluated in between-person designs. However, behaviour change theories apply to individuals not groups and behavioural interventions ultimately aim to achieve within-person rather than between-group change. Within-person methodology, such as N-of-1 (also known as single case design), can circumvent this issue, though has multiple design-specific challenges. This paper provides a conceptual review of the challenges and potential solutions for undertaking N-of-1 studies in health psychology. Key challenges identified include participant adherence to within-person protocols, carry-over and slow onset effects, suitability of behaviour change techniques for evaluation in N-of-1 experimental studies, optimal allocation sequencing and blinding, calculating power/sample size, and choosing the most suitable analysis approach. Key solutions include involving users in study design, employing recent technologies for unobtrusive data collection and problem solving by design. Within-person designs share common methodological requirements with conventional between-person designs but require specific methodological considerations. N-of-1 evaluation designs are appropriate for many though not all types of interventions. A greater understanding of patterns of behaviours and factors influencing behaviour change at the within-person level is required to progress health psychology into a precision science.

Health Behavior Change in Older Adults: Testing the Health Action Process Approach at the Inter- and Intraindividual Level.

BACKGROUND: Health behavior change theories usually claim to be universally and individually applicable. Most research has tested behavior change theories at the interindividual level and within young-to-middle-aged populations. However, associations at the interindividual level can differ substantially from associations at the intraindividual level. This study examines the applicability of the Health Action Process Approach (HAPA) at the inter- and the intraindividual level among older adults. METHODS: Two intensive longitudinal studies examined the HAPA model covering two different health behaviors and two different time spans: Study 1 (physical activity, N = 52 × 6 monthly observations) and Study 2 (medication adherence, N = 64 × 30 daily observations). The HAPA constructs (risk awareness, outcome expectancy, self-efficacy, intention, action planning, action control), and self-reported behaviors were assessed. RESULTS: Overall, at the interindividual level, results of both studies largely confirmed the associations specified by the HAPA. At the intraindividual level, results were less in line with the HAPA. Only action control emerged as consistent predictor of behavior. CONCLUSIONS: This study emphasises the importance of examining health behavior change theories at both, the inter- and the intraindividual level.

Assessing adherence to multiple medications and in daily life among patients with multimorbidity.

OBJECTIVE: Chronic conditions often require multiple medication intake. However, past research has focused on assessing overall adherence or adherence to a single index medication only. This study explored adherence measures for multiple medication intake, and in daily life, among patients with multiple chronic conditions (i.e. multimorbidity). DESIGN: Eighty-four patients with multimorbidity and multiple-medication regimens completed three monthly panel questionnaires. A randomly assigned subsample additionally completed a 30-day daily diary. MAIN OUTCOME MEASURE: The Non-Adherence Report; a brief self-report measure of adherence to each prescribed medication (NAR-M), and in daily life. We further assessed the Medication Adherence Report Scale (MARS), and a subsample of participants were randomised to electronic adherence monitoring. RESULTS: The NAR-M indicated M = 94.7% adherence at Time 1 (SD = 9.3%). The NAR-M was significantly correlated with the MARS (rt1 = .52, rt2 = .57, and rt3 = .65; p < .001), and in tendency with electronically assessed adherence (rt2 = .45, rt3 = .46, p < .10). Variance components analysis indicated that between-person differences accounted for 10.2% of the variance in NAR-M adherence rates, whereas 22.9% were attributable to medication by person interactions. CONCLUSION: This study highlights the importance and feasibility of studying adherence to multiple medications differentially, and in daily life. Future studies may use these measures to investigate within-person and between-medication differences in adherence.
