Attentional avoidant biases as mediators in the association between experiential avoidance and blood pressure in dementia family caregivers

An integrated model of psychosocial correlates of insomnia severity in family caregivers of people with dementia

OBJECTIVES

Research has shown the relevance of stress and coping factors in explaining caregivers' insomnia symptoms. However, few attempts have been made to empirically test an integrative model for insomnia severity in family caregivers of people with dementia. The aim of this study was to test such a model, in which insomnia severity is proposed to be influenced by predisposing factors, precipitated by stressors, and perpetuated by behaviors to cope with these stressors.

METHODS

311 family caregivers of people with dementia were assessed for variables categorized as predisposing (e.g. female gender), precipitating (e.g. care-recipient's behavioral and psychological symptoms of dementia [BPSD]), and perpetuating factors (e.g. sleep aids). A theoretical model was developed and then statistically tested using structural equation modelling, analyzing the direct and indirect effects of the assessed variables on caregivers' insomnia severity.

RESULTS

Distress, sleep aids, and experiential avoidance showed a direct association with insomnia severity. Female gender, younger age, cognitive fusion, leisure activities, dysfunctional thoughts, frequency and distress caused by care-recipient's BPSD showed indirect associations with insomnia severity. The model explained 22% of the variance of caregivers' insomnia severity.

CONCLUSION

The results provide additional empirical support for the importance of predisposing, precipitating and perpetuating factors associated with caregivers' insomnia severity. The integrative model we propose may also be useful for developing interventions targeting insomnia symptoms in family dementia caregivers.

Profiles of Dementia Caregivers according to Psychosocial and Resource Variables. Importance of Kinship

The present study aims to analyze the existence of different profiles in family caregivers of people with dementia according to psychosocial and resource variables. In addition, it aims to study whether there is a greater representation of each kinship group in each of the profiles and if there are differences in emotional distress among such profiles considering the kinship with the care-recipient. Participants were 288 family dementia caregivers, divided into four kinship groups (wives, husbands, sons and daughters). Psychosocial (familism, dysfunctional thoughts and experiential avoidance), resource (leisure activities and social support) and outcomes (depressive, anxious and guilt symptomatology) variables were collected. A hierarchical cluster analysis using Ward's method, an exploratory factor analysis of two fixed factors and contingency tables were performed. Five clusters were obtained: Low psychosocial vulnerability-High resources, Low psychosocial vulnerability-Low resources, Mixed, High psychosocial vulnerability-High resources, and High psychosocial vulnerability-Low resources. Results suggested that clusters associated with lower distress were the Low psychosocial vulnerability-High resources and the High psychosocial vulnerability-High resources. Clusters associated with higher distress were the Low psychosocial vulnerability-Low resources and Mixed. High levels of dysfunctional thoughts, familism and experiential avoidance do not always have a maladaptive function. This could depend on sociocultural and resource variables such as the kinship with the caregiver or perceived social support. The identification of profiles of family caregivers potentially needing protection and vulnerable to psychological distress could help to increase the effectiveness of interventions aimed at this population.

Clinically elevated depression scores do not produce negative attentional biases in caregivers of autistic children

Objective

Depression scores in caregivers of autistic children often fall in the clinical range. The attention of clinically depressed individuals tends to be biased toward negatively toned information. Whether caring for an autistic child might also be characterized by a negative attentional bias was explored here.

Methods

A sample of N = 98 (57 caregivers and 41 controls) completed questionnaires assessing depressive symptoms. Orienting attention to (i.e., vigilance), and shifting attention away from (i.e., disengagement), negative information was assessed via an online version of the emotional face dot probe task.

Results

Mean depression scores in caregivers, falling in the borderline clinical range, were significantly higher compared with controls. Groups, however, were indistinguishable with respect to vigilance and disengagement, and these attentional indices were unrelated to depression scores.

Conclusion

Caring for an autistic child, while associated with borderline clinical depression scores, was not characterized by a negative attentional bias. Findings are discussed in the context of methodological shortcomings and recommendations for future research.

Sociocultural factors, guilt and depression in family caregivers of people with dementia. Kinship differences

OBJECTIVES

This study aims to analyze the role that family obligations and social desirability have for understanding guilt and depressive symptoms in family caregivers. A theoretical model is proposed to analyze this significance based on the kinship with the person cared for.

METHODS

Participants are 284 family caregivers of people with dementia divided into four kinship groups (husbands, wives, daughters and sons). Face-to-face interviews were conducted assessing sociodemographic variables, familism (family obligations), dysfunctional thoughts, social desirability, frequency and discomfort associated with problematic behaviors, guilt and depressive symptoms. Path analyses are performed to analyze the fit of the proposed model and multigroup analysis to study potential differences between kinship groups.

RESULTS

The proposed model fits the data well and explains significant percentages of variance of guilt feelings and depressive symptomatology for each group. The multigroup analysis suggests that, for daughters, higher family obligations were associated with depressive symptomatology through a report of higher dysfunctional thoughts. For daughters and wives, an indirect association between social desirability and guilt was observed through reaction to problematic behaviors.

CONCLUSION

The results support the need to consider the significance of sociocultural aspects such as family obligations and the desirability bias in the design and implementation of interventions for caregivers, especially for daughters. Considering that the variables that contribute to explaining caregivers' distress vary depending on the relationship with the person cared for, individualized interventions may be warranted depending on the kinship group.

Family Caregivers of People with Dementia Associate with Poor Health-Related Quality of Life: A Nationwide Population-Based Study

Despite the growing awareness of poor health-related quality of life (HRQoL) in family caregivers of people with dementia (PWD), their relationship has rarely been explored with population-based samples. The current cross-sectional study aimed to determine the detrimental impact of informal dementia caregiving on HRQoL by using nationally representative population-based samples from the Korean Community Health Survey. Demographics, socioeconomic, and physical and mental health-related characteristics as well as HRQoL measured by the Korean version of the European Quality of Life Questionnaire Five Dimension (EQ-5D) were compared between 9563 family caregivers of PWD and 186,165 noncaregivers. Caregivers had lower index scores and higher frequency of some/extreme problems in all five dimensions of the EQ-5D compared with noncaregivers. Logistic regression adjusting for potential confounding factors found that caregivers had a higher frequency of poor HRQoL (lowest quartile of EQ-5D index) than noncaregivers (adjusted odds ratio [95% confidence interval] = 1.46 [1.39-1.53]). Compared to noncaregivers, caregivers had a higher frequency of some/extreme problems in each dimension of the EQ-5D: mobility (1.30 [1.21-1.40]), self-care (1.62 [1.46-1.80]), usual activity (1.39 [1.29-1.51]), pain/discomfort (1.37 [1.31-1.45]), and anxiety/depression (1.51 [1.42-1.61]). A one-to-one propensity score matching analysis confirmed that poor HRQoL was more frequently found in caregivers compared to noncaregivers (1.38 [1.29-1.48]). Our results indicated that family caregivers of PWD are significantly associated with overall poor HRQoL, underscoring the detrimental impact of informal dementia caregiving on HRQoL. Given the high frequency of poor HRQoL in dementia caregivers and the important recognition of its serious consequences on physical and mental health, clinicians should take into consideration efficient interventions to improve health and HRQoL for family caregivers of PWD.

"I Feel Guilty". Exploring Guilt-Related Dynamics in Family Caregivers of People with Dementia

Objectives: Family caregivers of people with dementia often report feelings of guilt. However, the number of studies analyzing guilt and the factors associated with its appearance are scarce. The aim of this study is to explore the subjective experience of guilt in the family care of people with dementia.Methods: A qualitative analysis of the narratives of 13 family caregivers of people with dementia about their feelings of guilt was done.Results: Seven categories for understanding guilt in caregiving were obtained: guilt derived from actions themselves; guilt derived from one's limitations; guilt for feeling negative emotions; guilt associated with the change in the relationship with the person cared for; guilt for neglecting other areas; guilt induced by the person cared for, and guilt induced by others. The results showed the existence of cases in which guilt is absent by distress-avoiding processes.Conclusions: Guilt is a relevant variable in understanding caregiver distress, and its analysis is necessary for therapeutic work in the field of care.Clinical implications: Psychological interventions aimed at family caregivers should include specific techniques in order to address guilt feelings.

To pay attention or not: The associations between attentional bias towards negative emotional information and anxiety, guilt feelings, and experiential avoidance in dementia family caregivers

Caring for a relative with dementia has been linked to negative consequences for caregivers' psychological health, such as anxiety or guilt. Cognitive theories of psychopathology propose that attentional bias towards negative stimuli contribute to the development and maintenance of emotional disorders and clinical symptomatology. However, attentional bias has scarcely been explored in dementia family caregivers. The aim of this study was to examine the relationship between attentional bias and anxiety symptomatology, guilt feelings, and experiential avoidance in a sample of dementia family caregivers. Participants were 226 dementia family caregivers. Attentional bias was measured using a novel priming adaptation of the dot-probe task. The sample was divided into high and low anxiety symptomatology, guilt feelings, and experiential avoidance groups. The results revealed two opposite patterns of emotional information processing in dementia family caregivers. While anxiety was found to be associated with an attentional preference for negative information, experiential avoidance was related to attentional avoidance of this information. Although guilt was also related to an attentional preference for negative information, this relationship was no longer significant when controlling for anxiety levels. These inflexible attentional patterns may have negative clinical consequences, given that in both cases relevant information necessary for adaptive coping with the stressful situation of caregiving may be unattended to or omitted.

Longitudinal Correlates of Depressive Symptoms and Positive and Negative Affects in Family Caregivers of People With Dementia

OBJECTIVE

Caring for a relative with dementia is considered a chronically stressful role associated with negative consequences for psychological health such as higher levels of depression. However, the subjective experience of depressive symptomatology is complex as it relates to two unique domains: positive affect (PA) and negative affect (NA). The objective of this study was to analyze, through a longitudinal design, the associations of caregivers' cognitive (avoidance coping, personal mastery, and coping self-efficacy) and behavioral (frequency of pleasant events) coping strategies with depressive symptoms, PA, and NA.

METHODS

A total of 111 caregivers of a spouse with dementia participated in this study. They were assessed yearly across 5 years. Mixed model regression analyses were conducted separately for depressive symptoms, PA, and NA, analyzing within and between-person associations of caregivers' age, gender, role overload, sleep quality, and coping variables previously mentioned.

RESULTS

The results showed that different coping strategies were associated with different components of depressive symptomatology. While avoidant coping was associated with NA and depressive symptoms but not PA at both within- and between-person levels, frequency of pleasant events was associated only with NA and depressive symptoms at the within-person level, showing no effect at the between-person level. Personal mastery and coping self-efficacy were found to be more transversal variables, being associated with most of the mood outcomes in both within and between-person effects.

CONCLUSION

Findings support the concept of depressive mood as a complex construct and highlights the importance of analyzing different coping strategies when trying to comprehend the caregiving stress process.

Family Caregivers of People with Dementia Have Poor Sleep Quality: A Nationwide Population-Based Study

Previous studies have documented cognitive impairments, psychological stress, and depressive symptoms in family caregivers of people with dementia (PWD), which could be attributed to their sleep disturbances. Notwithstanding the increasing recognition of poor sleep quality and sleep disturbances in family caregivers of PWD, their association has not been tested yet using population-representative samples. We conducted a retrospective, cross-sectional study using population-based data from the 2018 Korean Community Health Survey. Sociodemographic, mental health-related, and physical health-related variables as well as sleep quality evaluated by the Pittsburgh Sleep Quality Index (PSQI) were compared between 2537 cohabitating caregivers of PWD, 8864 noncohabitating caregivers of PWD, and 190,278 non-caregivers. Two sets of multivariable logistic regressions were conducted to examine the associations between dementia caregiving and poor sleep quality in cohabitating and noncohabitating caregivers versus noncaregivers. Both cohabitating and noncohabitating caregivers had higher global PSQI scores and higher prevalence of poor sleep quality (PSQI score > 5) than did noncaregivers. Multivariable logistic regressions adjusted for potential confounders revealed that cohabitating caregivers (odds ratio (OR) 1.26, 95% confidence interval (CI) 1.15-1.38) and noncohabitating caregivers (OR 1.15, CI 1.10-1.21) were significantly associated with poor sleep quality. Our results showed that both cohabitating and noncohabitating caregivers of PWD experienced overall poorer sleep quality compared to noncaregivers, indicating the deleterious effect of dementia caregiving on sleep quality, regardless of living arrangements. Given the high prevalence of poor sleep quality in family caregivers of PWD and the increasing awareness of the serious health consequences of poor-quality sleep, physicians should consider active sleep interventions to promote health and wellbeing not only for the dementia patients but also for family caregivers.

Development and Validation of an Implicit Relational Assessment Procedure (IRAP) to Measure Implicit Dysfunctional Beliefs about Caregiving in Dementia Family Caregivers

Caregivers of people with dementia who endorse dysfunctional beliefs about caregiving are at high risk of experiencing higher levels of distress. These dysfunctional beliefs are presented in the form of rules, verbal statements that specify what responsibilities one should expect in order to be a “good caregiver,” and are characterized as rigid, unrealistic, or highly demanding. Previous studies relied exclusively on self-report measures when assessing such dysfunctional beliefs about caregiving. The objectives of this study were: 1) to develop and validate an Implicit Relational Assessment Procedure (IRAP) to measure implicit dysfunctional beliefs about caregiving (CARE-IRAP), and 2) considering the relatively high age of the sample, to analyze the adaptation of the IRAP for older adults, comparing the IRAP performance between older adult caregivers and middle-aged caregivers. Participants were 123 dementia family caregivers with a mean age of 62.24 ± 12.89. Adaptations were made to the IRAP by adjusting the accuracy and response time criteria. The sample was split into middle-aged caregivers (below 60 years) and older adult caregivers (60 or older). The CARE-IRAP scores presented significant positive correlations with explicit measures of dysfunctional beliefs about caregiving and experiential avoidance in caregiving. A similar pattern of results was observed across the two age groups. The results revealed that caregivers endorse implicit dysfunctional beliefs about caregiving and offer preliminary support for the use of the IRAP as a valid measure of implicit caregiving beliefs. This exploratory study is the first to adapt the IRAP criteria to older adults, and future studies should further explore criteria suitable for this population.

Factors associated with the risk of cardiovascular disease in family caregivers of people with dementia: a systematic review

Objective

This study aimed to systematically review studies that reported factors associated with the risk of cardiovascular disease (CVD) in family caregivers of people with dementia (PWD).

Methods

Literature was searched in PubMed, Medline, CINAHL, and PsycINFO using keywords generated from the terms “dementia”, “caregiver”, and “cardiovascular disease”. We included studies that examined factors associated with CVD risk in family caregivers of PWD, those with longitudinal or cross-sectional study designs, and those published in English.

Results

A total of 34 studies were included in this review. Stress and depressive symptoms, pleasant leisure activity, coping self-efficacy and coping strategy, physical activity, and social support were the main modifiable associated factors of CVD risk in family caregivers of PWD. However, the association between sleep and CVD risk was unclear. Caregiving status, the duration of caregiving, genes, and race, were the main non-modifiable associated factors of CVD risk in family caregivers.

Conclusion

This review showed seven modifiable factors of CVD risk. In particular, leisure activities, physical activity, and social support were significantly negatively associated with the risk of CVD. Researchers and clinical professionals are recommended to consider these risk factors when they develop interventions to reduce CVD risk in family caregivers of PWD.

Stress and Blood Pressure in Dementia Caregivers: The Moderator Role of Mindfulness

Objective: Dementia caregiving has been described as a chronically stressful situation with adverse cardiovascular effects. Psychological resources such as mindfulness may reduce the impact of stress on caregivers' cardiovascular health. The objective of this study was to analyze the moderating effect of trait mindfulness on the relationship between frequency of disruptive behaviors of the care recipient and blood pressure (BP) in dementia caregivers. Method: Participants were 110 dementia family caregivers. Two hierarchical regressions (for systolic and diastolic BP) were conducted to analyze whether mindfulness moderates the relationship between disruptive behaviors and BP after controlling for known predictors of cardiovascular outcomes. Results: A significant moderator effect of mindfulness was found between the frequency of disruptive behaviors and diastolic BP (β = -.195, p < .05). Among those caregivers reporting low levels of mindfulness, the relationship between frequency of disruptive behaviors and diastolic BP was relatively stronger than among those reporting high mindfulness levels. Conclusions: The results suggest that a high level of trait mindfulness may have protective effect on BP when caregivers face high levels of stress. Clinical Implications: Mindfulness seems to be an important variable with potential for buffering the effects of caregiving stressors on caregivers' blood pressure.

Developing professional caregivers' empathy and emotional competencies through mindfulness-based stress reduction (MBSR): results of two proof-of-concept studies

OBJECTIVES

To assess the feasibility and acceptability of a mindfulness-based stress reduction (MBSR)-based intervention and determine if the intervention is associated with a significant signal on empathy and emotional competencies.

DESIGN

Two pre-post proof-of-concept studies.

SETTING

Participants were recruited at the University of Montreal's Psychology Department (Study 1) and the CHU Sainte-Justine Department of Hematology-Oncology (Study 2).

PARTICIPANTS

Study 1: 12 students completed the 8-week programme (mean age 24, range 18-34). Study 2: 25 professionals completed the 8-week programme (mean age 48, range 27-63).

INTERVENTION

Standard MBSR programme including 8-week mindfulness programme consisting of 8 consecutive weekly 2-hour sessions and a full-day silent retreat.

OUTCOMES MEASURES

Mindfulness as measured by the Mindful Attention Awareness Scale; empathy as measured by the Interpersonal Reactivity Index (IRI)'s Perspective Taking and Empathic Concern subscales; identification of one's own emotions and those of others as measured by the Profile of Emotional Competence (PEC)'s Identify my Emotions and Identify Others' Emotions subscales; emotional acceptance as measured by the Acceptance and Action Questionnaire-II (AAQ-II) and the Emotion Regulation Scale (ERQ)'s Expressive Suppression subscale; and recognition of emotions in others as measured by the Geneva Emotion Recognition Test (GERT).

RESULTS

In both studies, retention rates (80%-81%) were acceptable. Participants who completed the programme improved on all measures except the PEC's Identify Others' Emotions and the IRI's Empathic Concern (Cohen's d median=0.92, range 45-1.72). In Study 2, favourable effects associated with the programme were maintained over 3 months on the PEC's Identify my Emotions, the AAQ-II, the ERQ's Expressive Suppression and the GERT.

CONCLUSIONS

The programme was feasible and acceptable. It was associated with a significant signal on the following outcomes: perspective taking, the identification of one's own emotions and emotional acceptance, thus, justifying moving towards efficacy trials using these outcomes.
