Mindfulness in informal caregivers of palliative patients

Existential distress in family caregivers: scoping review of meaning-making interventions

OBJECTIVES

Family and friend caregivers often feel overwhelmed by and ill-prepared for their responsibilities. Many feel helpless living with uncertainty about the outcome of the patient's illness, which leads to existential distress. Supportive care interventions that address existential distress by promoting meaning and purpose buffer the negative effects of caregiver burden and promote resilience and growth. The purpose of this scoping review is to describe the depth and breadth of available interventions targeting caregiver existential distress.

METHODS

We followed the Joanna Briggs Institute's scoping review methods and applied the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Extension checklist. SCOPUS, Ovid MEDLINE and PsycINFO databases were searched for interventions that targeted existential distress by promoting meaning-making, spiritual well-being, post-traumatic growth and/or benefit finding for caregivers of seriously ill adult patients.

RESULTS

We screened 1377 titles/abstracts and 42 full-text articles. Thirty-one articles (28 unique studies) met inclusion criteria. Most interventions were designed for caregivers supporting patients with cancer (n=14) or patients receiving palliative care (n=9). Promising interventions included Meaning-Centered Psychotherapy for Cancer Caregivers, Meaning-Based Intervention for Patients and their Partners, Legacy Intervention for Family Enactment, Family Participatory Dignity Therapy and Existential Behavioural Therapy. More than half of the studies (n=20, 64%) were in the feasibility/acceptability/pilot stage of intervention testing.

CONCLUSION

Large randomised controlled trials with more diverse samples of caregivers are needed. Future research should explore the impact of delivering meaning-making interventions to caregivers throughout the illness trajectory. Developing strategies for scaling up and conducting cost analyses will narrow the research and practice gap for meaning-making interventions.

A systematic review and meta-analysis of psychological interventions to improve mental wellbeing

Our current understanding of the efficacy of psychological interventions in improving mental states of wellbeing is incomplete. This study aimed to overcome limitations of previous reviews by examining the efficacy of distinct types of psychological interventions, irrespective of their theoretical underpinning, and the impact of various moderators, in a unified systematic review and meta-analysis. Four-hundred-and-nineteen randomized controlled trials from clinical and non-clinical populations (n = 53,288) were identified for inclusion. Mindfulness-based and multi-component positive psychological interventions demonstrated the greatest efficacy in both clinical and non-clinical populations. Meta-analyses also found that singular positive psychological interventions, cognitive and behavioural therapy-based, acceptance and commitment therapy-based, and reminiscence interventions were impactful. Effect sizes were moderate at best, but differed according to target population and moderator, most notably intervention intensity. The evidence quality was generally low to moderate. While the evidence requires further advancement, the review provides insight into how psychological interventions can be designed to improve mental wellbeing.

Illness-Related Parenting Stress and Maladjustment in Congenital Heart Disease: Mindfulness as a Moderator

OBJECTIVE

Congenital heart disease (CHD) is characterized by structural defects to the heart or the coronary blood vessels and often requires surgical repair. Raising an infant or toddler with CHD can be challenging and lead to high parenting stress and maladjustment. The parenting literature suggests that mindfulness may buffer parenting stress. The purpose of this study was to examine whether mindfulness might moderate the relationship between illness-related parenting stress and maladjustment in parents of infants and toddlers with CHD.

METHODS

Parents of infants and toddlers with CHD attending an outpatient clinic provided background information and completed measures of illness-related parenting stress, mindfulness, and maladjustment.

RESULTS

Results indicated that illness-related parenting stress was associated with maladjustment, and mindfulness moderated this relationship. Specifically, illness-related parenting stress was related to maladjustment at low and average levels of mindfulness; at high mindfulness, there was no association between illness-related parenting stress and maladjustment.

CONCLUSIONS

Consistent with the broader literatures, our sample of parents of infants and toddlers with CHD reported high illness-related parenting stress and maladjustment. Building on other studies demonstrating the benefits of mindful parenting, our results suggest that engaging in mindfulness might thwart the association between illness-related parenting stress and maladjustment in parents of infants and toddlers with CHD.

Psychometric properties of the WHOQOL-BREF among next of kin to older persons in nursing homes

Background

The worries of next of kin about their older loved ones in nursing homes can be extensive and can adversely affect their subjective experiences of their own physical, mental and social well-being. It is thus of utmost importance to measure the quality of life of next of kin in a valid and reliable way.

Methods

The design is a cross-sectional study with psychometric evaluation based on classical test theory in preparation for a planned educational intervention study on palliative care. An abbreviated version of the World Health Organization’s quality-of-life self-assessment instrument WHOQOL, the Swedish WHOQOL-BREF, was completed by 254 next of kin of older persons in 30 nursing homes. Data quality was assessed via the mean, median, item response, missing values, and floor and ceiling effects. Reliability was estimated using Cronbach’s alpha and corrected item-total correlations. Construct validity was estimated by Spearman’s rank correlation, and model fit was assessed using confirmatory factor analysis.

Results

The rate of missing data was low (less than 2%). Ceiling effects ranged from 11 to 43% and were above 20% for 21 of 24 items. The corrected item-total correlations varied between 0.35 and 0.68 and were thus well above the lower limit of 0.30. Cronbach’s alpha was 0.83, indicating satisfactory internal consistency. The confirmatory factor analysis indicated a fair to close model fit (comparative fit index 0.93, root mean squared error of approximation 0.06).

Conclusions

The findings suggest that the WHOQOL-BREF may constitute a reliable and valid measure of quality of life for use among next of kin to older persons in nursing homes. When interpreting the results, it is important to assess the ceiling effect, as it may restrict the ability of the WHOQOL-BREF to detect true positive changes in quality of life over time.

The relationship between trait mindfulness and affective symptoms: A meta-analysis of the Five Facet Mindfulness Questionnaire (FFMQ)

Trait mindfulness appears to be related to lower levels of negative affective symptoms, but it remains uncertain which facets of mindfulness are most important in this relationship. Accordingly, the present meta-analysis examined studies reporting correlations between affective symptoms and trait mindfulness as assessed by the Five Facet Mindfulness Questionnaire. A comprehensive search yielded 148 eligible studies, comprising 157 distinct samples and 44,075 participants. The weighted mean correlation for affective symptoms and overall trait mindfulness was r = -0.53. Among mindfulness facets, Nonjudge (r = -0.48) and Act with Awareness (r = -0.47) demonstrated the largest correlations, followed by Nonreact (r = -0.33) and Describe (r = -0.29). Observe was not significantly correlated with affective symptoms. No significant differences in the strength of correlations were found between anxiety, depression and posttraumatic stress disorder (PTSD) symptoms, though symptoms of generalized anxiety disorder exhibited a weaker negative relationship with the Describe facet compared to PTSD symptoms. Describe also showed a stronger relationship with affective symptoms in Eastern samples compared to Western samples, whereas Western samples had a stronger relationship with Nonjudge. These results provide insight into the nature of the association between trait mindfulness and negative affect.

Spiritual Care in Palliative Care: A Systematic Review of the Recent European Literature

Many studies on spiritual care in palliative care are performed in the US, leaving other continents unexplored. The objective of this systematic review is to map the recent studies on spiritual care in palliative care in Europe. PubMed, CINAHL, ATLA, PsycINFO, ERIC, IBSS, Web of Science, EMBASE, and other databases were searched. Included were European studies published in a peer-reviewed journal in 2015, 2016, or 2017. The characteristics of the included studies were analyzed and a narrative synthesis of the extracted data was performed. 53 articles were included. Spiritual care was seen as attention for spirituality, presence, empowerment, and bringing peace. It implied creative, narrative, and ritual work. Though several studies reported positive effects of spiritual care, like the easing of discomfort, the evidence for spiritual care is low. Requirements for implementation of spiritual care in (palliative) care were: Developing spiritual competency, including self-reflection, and visibility of spirituality and spiritual care, which are required from spiritual counselors that they participated in existing organizational structures. This study has provided insight into spiritual care in palliative care in Europe. Future studies are necessary to develop appropriate patient outcomes and to investigate the effects of spiritual care more fully.

Dyadic coping in specialized palliative care intervention for patients with advanced cancer and their caregivers: Effects and mediation in a randomized controlled trial

OBJECTIVE

Specialized palliative care (SPC) interventions increasingly include patient-caregiver dyads, but their effects on dyadic coping are unknown. We investigated whether an SPC and dyadic psychological intervention increased aspects of dyadic coping in patients with advanced cancer and their caregivers, whether dyad characteristics moderated effects and whether aspects of dyadic coping mediated significant intervention effects on caregivers' anxiety and depression.

METHODS

We randomized 258 patients with incurable cancer and their caregivers to care as usual or accelerated transition from oncological treatment to home-based SPC and dyadic psychological support. In secondary outcome analyses, using mixed-effects models, we estimated intervention effects and 95% confidence intervals (CIs) for communication of stress and common coping, and moderation by dyad type and demographics. In path analyses, we investigated whether stress communication and common coping mediated intervention effects on caregivers' symptoms of anxiety and depression. (Clinicaltrials.gov NCT01885637).

RESULTS

The intervention significantly increased common coping in patients and caregivers in couples (estimated difference, 0.68; 95% CI, 0.11 to 1.24) and stress communication by partner caregivers (0.97; 0.24 to 1.24). We found some support for different intervention effects for spouses and other dyads, but no evidence of mediation.

CONCLUSIONS

Specialized palliative care and dyadic psychological intervention may affect aspects of dyadic coping. Common coping and stress communication did not mediate the previously found significant intervention effects on caregiver anxiety and depression, indicating that other mechanisms may have been central in the intervention.

Sources of meaning in family caregivers of terminally ill patients supported by a palliative nursing care team: A naturalistic three-month cohort study

ABSTRACTObjective:Our aim was to identify possible patterns of change or durability in sources of meaning for family caregivers of terminally ill patients after the onset of support at home by an outreach palliative nursing team during a three-month survey period.

METHOD

The Sources of Meaning and Meaning in Life Questionnaire (SoMe) was administered to 100 caregivers of terminally ill patients at four measurement timepoints: immediately before the onset of the palliative care (t0), and at 1 week, 1 month, and 3 months after t0. Time-dependent changes were assessed for the completed subsample (n = 24) by means of bivariate linear as well as quadratic regression models. Multivariate regressions with dimensions of meaning in life as dependent variables were performed for the whole sample by means of random-effects models: dependent variables changed over time (four timepoints), whereas regressors remained constant.

RESULTS

No significant differences were found for psychosocial and clinical variables or for sources of meaning between the uncompleted and completed subsamples. Growth curve analyses revealed no statistically significant but tendentiously parabolic changes for any dimensions or for single sources of meaning. In multivariate models, a negative association was found between patient age, psychological burden of family caregivers, and changes in total SoMe score, as well as for the superordinate dimensions.

SIGNIFICANCE OF RESULTS

According to our hypothesis, sources of meaning and meaning in life seem to remain robust in relatives caring for terminally ill family members during the three-month survey period. A parabolic development pattern of single sources of meaning indicates an adjustment process. An important limitation of our study is the small number of participants compared with larger multivariate models because of high dropout rates, primarily due to the death of three-quarters of the participants during the survey period.

The feasibility and acceptability of short-term, individual existential behavioural therapy for informal caregivers of patients recruited in a specialist palliative care unit

Background

Existential behavioural therapy (EBT) is a recently developed intervention to support informal caregivers of patients in a specialist palliative care unit and was initially established as a six-session group programme. This pilot study aimed to test the feasibility and acceptability of an adapted short-term, individual approach of EBT in preparation for a randomized controlled trial (RCT).

Methods

The study was conducted in a prospective, mixed methods design including four quantitiative assessments with embedded qualitative interviews at one assessment.

The intervention offered two one-hour therapeutic sessions focusing on (1) mindfulness and (2) existential meaning-in-life as a source of strength provided by a trained psychotherapist. To test the feasibility of the intervention, doubling of the participation rate, compared to the previous group study (13,6 %) as well as an attrition rate of less than 30 % were set as thresholds. To test the acceptability of the intervention, self-rated usefulness of individual aspects of the intervention and the frequency of implementing therapeutic elements by the carers were set as criteria. Acceptability testing also included the number of participants who completed both sessions, where we expected more than 75 % as a criterion for acceptability. Return rates of quantitative questionnaires were set as criteria for the feasibility of data collection (<33 % loss expected within the study period). Qualitative interviews were used to collect additional data on feasibililty and acceptability and to explore potential harms and benefits of the intervention.

Results

44/102 (43,1 %) of eligible informal caregivers agreed to participate in the study. Due to attrition of 13 caregivers (attrition rate: 29,5 %), 31 caregivers were included in the trial. Self-rated usefulness showed sufficiant results for all but one individual aspect. Frequency of implementing therapeutic elements showed wide inter-item as well as inter-participant ranges and decreased over the study period. All participants completed both sessions. Return rates of the questionnaires were within the expected range. According to the interviews, the intervention was associated with several participant-identified benefits. No severe adverse effects were observed.

Conclusions

Findings suggest that the short-term, individual EBT proved feasible and mostly acceptable.

Evaluating the effects of mindfulness-based interventions for informal palliative caregivers: A systematic literature review

BACKGROUND

There is a need to identify proactive, evidence-based interventions to support informal palliative caregivers. Mindfulness-based interventions, evidenced in the literature as providing physical and mental health benefits for diverse populations, may have application in the setting of palliative caregiving.

AIM

To describe, evaluate and synthesise the peer-reviewed literature on the effects of mindfulness-based interventions for informal palliative caregivers.

DESIGN

A Systematic Literature Review according to the Preferred Reporting Items for Systematic Review and Meta Analyses guidelines and a Narrative synthesis.

DATA SOURCES

The Cochrane Library, CINAHL, MEDLINE, PsycINFO and EMBASE databases, searched from inception to February 2014 and references of included studies.

RESULTS

A total of 13 articles, reporting 10 studies (n = 432 participants) were included. All studies were conducted in the last 5 years. Dementia caregivers were the most frequently researched population (n = 7). Results suggest that mindfulness-based interventions are feasible and acceptable to offer to informal palliative caregivers and may provide benefit, particularly in terms of reducing depression and caregiver burden and increasing quality of life. However, effects were not as robust as findings in the wider mindfulness intervention literature.

CONCLUSION

This is the first systematic literature review on this topic. Results suggest both feasibility and potential benefit. Further qualitative research is required to explore the outcomes identified by informal caregivers themselves as the reduced magnitude of effect may suggest that we are not measuring the right outcomes in this context. This would inform more sensitive outcome measures for future intervention studies and guide the development and application of mindfulness-based models in this area.

Psychometric properties of carer-reported outcome measures in palliative care: A systematic review

BACKGROUND

Informal carers face many challenges in caring for patients with palliative care needs. Selecting suitable valid and reliable outcome measures to determine the impact of caring and carers' outcomes is a common problem.

AIM

To identify outcome measures used for informal carers looking after patients with palliative care needs, and to evaluate the measures' psychometric properties.

DESIGN

A systematic review was conducted. The studies identified were evaluated by independent reviewers (C.T.J.M., M.B., M.P.). Data regarding study characteristics and psychometric properties of the measures were extracted and evaluated. Good psychometric properties indicate a high-quality measure.

DATA SOURCES

The search was conducted, unrestricted to publication year, in the following electronic databases: Applied Social Sciences Index and Abstracts, Cumulative Index to Nursing and Allied Health Literature, The Cochrane Library, EMBASE, PubMed, PsycINFO, Social Sciences Citation Index and Sociological Abstracts.

RESULTS

Our systematic search revealed 4505 potential relevant studies, of which 112 studies met the inclusion criteria using 38 carer measures for informal carers of patients with palliative care needs. Psychometric properties were reported in only 46% (n = 52) of the studies, in relation to 24 measures. Where psychometric data were reported, the focus was mainly on internal consistency (n = 45, 87%), construct validity (n = 27, 52%) and/or reliability (n = 14, 27%). Of these, 24 measures, only four (17%) had been formally validated in informal carers in palliative care.

CONCLUSION

A broad range of outcome measures have been used for informal carers of patients with palliative care needs. Little formal psychometric testing has been undertaken. Furthermore, development and refinement of measures in this field is required.

Young clinicians dealing with death: Problems and opportunities

OBJECTIVE

The formation of a strong bond between patients and therapists can lead to successful treatment outcomes. Yet, little is known about the mechanisms that function to control this relationship. The objective of this case report was to examine the ruptures and repairs in the working alliance between a young therapist and an elderly caregiver, and to suggest ways in which to deal with age-related challenges to such an alliance.

METHOD

In order to examine the ruptures and repairs in a working alliance, this case report reflects on the interdependent relationship among therapist variables, patient variables, and the therapeutic alliance. The clinical experience presented describes a newly educated psychologist's struggles to overcome the challenges in forming a strong working alliance with an elderly dying cancer patient's spouse. The spouse was enrolled in the DOMUS study (Clinicaltrials.gov: NTC01885637), an ongoing randomized controlled trial of a patient-and-caregiver intervention for facilitating the transition from an oncology ward to palliative at-home care, and then bereavement. As part of the DOMUS study, the patient and spouse received a psychological intervention based on existential-phenomenological therapy.

RESULTS

A therapist's therapeutic approach to breaking down age-related barriers to communication matters greatly. The existential-phenomenological method of epoché offers a way to effectively address ruptures and repairs in a working alliance, as it enhances the therapist's openness to learning. In addition, the insights of senior supervisors can promote a therapist's openness to learning.

SIGNIFICANCE OF RESULTS

In conclusion, the method of epoché benefits the working alliance in several ways, as it enhances personal insight and provides methods for repairing an alliance. The reflections in this paper may be applied to clinical settings in oncology, gerontology, and palliative care, which are likely to be of great interest to young clinicians experiencing age-related challenges in their daily work.
