Exploring the impact of carer stressors and psychological inflexibility on depression and anxiety in family carers of people with dementia

Profiles of psychological flexibility and caregiving experience in dementia family caregivers: A latent profile analysis

OBJECTIVES

To explore the profiles of psychological flexibility among dementia family caregivers and examine their associations with psychological well-being and caregiving factors.

METHODS

Participants were 521 dementia family caregivers in Japan. Latent profile analysis was conducted to explore the profiles of psychological flexibility. The analyses examined differences in depression, anxiety, life satisfaction, and work-family conflict/enrichment between the profiles, and whether sociodemographic variables and caregiving stressors predict the profile.

RESULTS

Four distinct profiles were identified: high psychological flexibility (14.2%), moderate psychological flexibility with high commitment (24.7%), moderate psychological flexibility with low commitment (48.0%), and low psychological flexibility (13.1%). The low psychological flexibility profile exhibited the highest scores of depression, anxiety and work-family conflict, followed by the moderate psychological flexibility with low/high commitment profiles, and the high psychological flexibility profile. The high psychological flexibility and moderate psychological flexibility with high commitment profiles exhibited higher life satisfaction than the moderate psychological flexibility with low commitment profile. Caregiving stressors, marital status, and caregiver status predicted the profile.

CONCLUSION

Enhancing defusion and acceptance, rather than increasing commitment to personal values, may be beneficial in supporting distressed caregivers. Having more caregiving stressors, being single/divorced/bereaved, and being a primary caregiver may be useful indicators of decreased psychological flexibility among dementia family caregivers.

Family Caregivers' Progress Toward Values Moderates the Associations between Behavioral Symptoms of Dementia, Caregiver Burden, and Depressive Symptoms

Increasingly, dementia caregiver interventions are informed by acceptance-based approaches such as Acceptance and Commitment Therapy. These interventions promote psychological skills like psychological flexibility and value-based living. Less is known how these constructs interact within well-established caregiver stress processes. We examined a moderated mediation model (N = 161 dementia caregivers; PROCESS Procedure; SPSS Release 4.1), with BPSD frequency (Revised Memory and Behavior Problems Checklist) predicting depressive symptoms (10-item CES-D), mediated via caregiver burden (short Burden inventory). The moderator was the Values Questionnaire, and we controlled for gender, caregiver duration, age, income, and education. Results: revealed that the indirect effect of BPSD on depressive symptoms through caregiver burden was weakened through higher progress toward values (moderated mediation significant at p < .05). Committed action toward values signify caregivers' success at balancing care-related stress with other priorities. Interventions that build skills in values-based living have promise for caregivers, offering healthier ways to adjust to being a caregiver.

Caregiver Resilience and Dance/Movement Therapy: A Theoretical Review and Conceptual Model

With the population aging, more people are living with neurodegenerative conditions, leading to an influx of informal family caregivers, who often experience negative health outcomes. Few caregiver interventions have successfully adopted a holistic, strengths-based approach to fostering resilience. This article examines existing literature on caregiver resilience factors, which include self-efficacy, flexibility, cultivating positive emotions, and drawing on spiritual and social supports. Despite how dance/movement therapy (DMT) has been shown to foster psychological and physiological benefits, it remains underexplored for caregivers. Therapeutic mechanisms of DMT are expounded for their innate correspondence to resilience factors, and a new comprehensive model of DMT for caregiver resilience is presented, with implications for future intervention design and measurement.

Does Avoiding Distressing Thoughts and Feelings Influence the Relationship between Carer Subjective Burden and Anxiety Symptoms in Family Carers of People with Dementia?

Anxiety remains understudied in family carers of people with dementia. Understanding factors that moderate the relationship between stressors and anxiety symptoms in this population is critical to inform interventions. This study examined whether generic experiential avoidance (AAQ-II) and experiential avoidance specific to caregiving-related thoughts and feelings (EACQ) moderate the relationship between subjective burden (ZBI-12) and anxiety symptoms (GAD-7) in carers of people with dementia. The first model (R2 = .66, ∆R2 = .03) exploring the moderating effect of AAQ-II demonstrated a significant interaction term between AAQ-II and subjective burden. The second model (R2 = .53, ∆R2 = .03), exploring the moderating effect of EACQ, demonstrated a significant interaction term between EACQ and subjective burden. These results provide evidence that carers with higher levels of experiential avoidance may be particularly prone to the negative effect of subjective burden on anxiety symptoms. Clinical implications for assessment of experiential avoidance and its treatment in carers of people with dementia are discussed.

Reliability and validity of the Japanese version of the Valued Living Questionnaire Adapted to Caregiving

OBJECTIVES

This study developed the Japanese version of the Valued Living Questionnaire Adapted to dementia Caregiving (J-VLQAC) and assessed its reliability and validity.

METHODS

A 2-wave longitudinal survey with an interval of two weeks was conducted with Japanese dementia family caregivers (n = 521 at T1; n = 424 at T2).

RESULTS

Confirmatory factor analysis demonstrated a poor fit to our data for the original 2-factor model. Exploratory factor analysis resulted in a new 3-factor model (i.e., Own Values, Family Values, and Health Values). Both models showed similar good internal consistency (Cronbach's alpha) and test-retest reliability. Significant correlations between the J-VLQAC and the Valuing Questionnaire (VQ) and measures assessing related constructs (e.g., cognitive fusion) supported good criterion validity and acceptable level of construct validity for both models. Compared to the original 2-factor model, the new 3-factor model showed higher incremental validity, which was assessed through the hierarchical regression analysis examining whether the J-VLQAC predicts depression, anxiety, and life satisfaction over and above the VQ.

CONCLUSIONS

The J-VLQAC has good reliability and acceptable validity.

CLINICAL IMPLICATIONS

The information gathered from the J-VLQAC can be used to tailor psychological support and help caregivers engage in activities that reflect their personal values.

The feasibility and preliminary effects of a pilot randomized controlled trial: Videoconferencing acceptance and commitment therapy in distressed family caregivers of people with dementia

This pilot randomized controlled trial (RCT) examined preliminary effects of an 8-week videoconferencing acceptance and commitment therapy (ACT) program supplemented with psychoeducation materials on distressed family caregivers of persons living with dementia (PLWD) compared to the control group provided with psychoeducation materials only. Nineteen family caregivers of PLWD in the USA were randomly assigned to the ACT group or the control group. Data was collected at pretest, posttest, and 1-month follow-up (F/U). Compared to the control group, the ACT group showed a significantly larger reduction in grief at posttest, with a medium effect size. Small effects of ACT were found in anxiety, psychological quality of life, and engagement in meaningful activities at posttest and grief, engagement in meaningful activities, and psychological flexibility at F/U compared to the control group. These promising findings warrant a full-scale RCT with adequate power to measure the efficacy of videoconferencing ACT for caregivers of PLWD.

Examining the Impact of Different Components of Sleep Quality on Anxiety Among Family Carers of People with Dementia

Existing interventions for family carers of people with dementia tend to be less effective for anxiety than for depression. Therefore, identifying factors affecting carer anxiety is important to inform future interventions. This study conducted 2 multiple regression analyses using a sample of 91 family carers. The first regression model (∆R² = .24), exploring the impact of demographic variables and carer stressors, demonstrated that hours of caring (β = .33) and overall sleep quality (β = .28) were significant predictors of anxiety. To further investigate the impact of sleep quality, the second model (∆R² = .24) focussed on exploring the differential impact of various components of sleep quality on anxiety. Findings demonstrated that subjective sleep quality (β = .33) and sleep disturbances (β = .22) were significant predictors. Hours of caring per week, subjective sleep quality and sleep disturbances seem to be critical for treating anxiety in family carers. Future studies should investigate whether targeting these variables could improve carer anxiety.

Online counselling for family carers of people with young onset dementia: The RHAPSODY-Plus pilot study

Objective

Compared to late life dementia, Young Onset Dementia (YOD) has its own distinct challenges, including a lack of specialised and age-appropriate support services. Carers of people with YOD experience higher levels of psychological and physical symptoms, and lower quality of life. This study (RHAPSODY-Plus) assessed the acceptability and feasibility of combining RHAPSODY (Research to Assess Policies and Strategies for Dementia in the Young; a web-based information and skill-building programme for carers of people with YOD) with individually tailored support sessions with health professionals (a social worker and a clinical psychologist) provided via online videoconferencing.

Methods

Participants (n = 20) were informal carers aged over 18 years, who were caring for a person with YOD (either Alzheimer's disease or frontotemporal dementia type). Participants used the RHAPSODY programme for 4 weeks, then attended 2 support sessions. Participants and the health professionals then attended individual feedback sessions. Feedback was collected via open-ended and Likert-style questions.

Results

The majority of carers rated the RHAPSODY-Plus programme as good to very good, demonstrating a high level of acceptability. Positive feedback about the programme included being able to receive personal advice additionally to the information provided in RHAPSODY. The healthcare professionals also thought the programme was acceptable and beneficial for access to support. Some limitations in the feasibility of videoconferencing included network and technical issues and the loss of non-verbal communication.

Conclusions

This online pilot study had a high level of acceptability, demonstrating the potential of an individualised multi-modal intervention for carers of people with YOD which offers opportunities to overcome geographical and service access barriers.

Psychological Processes Associated With Resilience in UK-Based Unpaid Caregivers During the COVID-19 Pandemic

Background

Unpaid caregivers have faced and dealt with additional challenges during the COVID-19 pandemic. Understanding the psychological processes associated with their resilience is warranted. The objective of this study was to examine the associations between resilience with mental distress, emotion regulation strategies (i.e., reappraisal and suppression) and interpretation bias in adult caregivers.

Method

Participants were living in the UK, aged 18+, and consisted of 182 unpaid caregivers of an adult aged 18+ living with a long-term health condition, and 120 non-caregivers. Data were collected in an online study during the first national UK COVID-19 lockdown (May and September 2020). Hierarchical multiple regression analyses explored whether emotion regulation strategies and interpretation bias explained unique variance in levels of resilience in caregivers whilst controlling for anxiety and depression.

Results

Compared to non-caregivers, caregivers reported higher levels of anxiety, depression, negative interpretation bias and lower levels of resilience. Emotion regulation strategies did not differ between groups. Within caregivers, greater resilience was associated with lower mood disturbance, a positive interpretation bias, and greater use of cognitive reappraisal and lower use of suppression strategies to regulate emotions. Emotion regulation and interpretation bias together predicted an additional 15% of variance in current levels of resilience.

Conclusion

Our findings indicate that psychological mechanisms such as emotion regulation strategies, particularly reappraisal, and interpretation bias are associated with resilience in caregivers. Although preliminary, our findings speak to exciting clinical possibilities that could form the target of interventions to improve resilience and lower mental distress in unpaid caregivers.

Internet-facilitated interventions for informal caregivers of patients with neurodegenerative disorders: Systematic review and meta-analysis

Objective

This systematic review explored the effectiveness of internet-delivered interventions in improving psychological outcomes of informal caregivers for neurodegenerative-disorder (ND) patients.

Methods

We searched seven databases for English-language papers published from 1999 to May 2021. Study-eligibility required that interventions used a minimum 50% internet-facilitation, targeting unpaid, adult informal caregivers of community-based ND-patients. We included randomised controlled trials (RCTs) and pre-post evaluative studies reporting outcomes for at least one-time point post-intervention. Independent quality checks on abstract and full-text screening were completed. Data extraction encompassed interventions' features, approaches, theoretical bases and delivery-modes. The Integrated quality Criteria for the Review Of Multiple Study designs (ICROMS) framework assessed risk of bias. Alongside narrative synthesis, we calculated meta-analyses on post-intervention using outcome measures from at least two RCTs to assess effectiveness.

Results

Searches yielded 51 eligible studies with 3180 participants. In 48 studies, caregivers supported a dementia-diagnosed individual. Intervention-durations encompassed four weeks to 12 months, with usage-frequency either prescribed or participant-determined. The most frequently-used approach was education, followed by social support. We calculated meta-analyses using data from 16 RCTs. Internet-delivered interventions were superior in improving mastery (g  =  1.17 [95% CI; 0.1 to 2.24], p  =  0.03) and reducing anxiety (g = -1.29 [95% CI; -1.56 to -1.01], p < 0.01), compared to all controls. Findings were equivocal for caregivers' quality of life, burden and other outcomes. High heterogeneity reflected the multifarious combinations of approaches and delivery-modes, precluding assessment of the most efficacious intervention features. Analyses using burden and self-efficacy outcomes' follow-up data were also non-significant compared to all comparator-types. Although 32 studies met the ICROMS threshold scores, we rated most studies' evidence quality as 'very-low'.

Conclusions

This review demonstrated some evidence for the efficacy of internet-delivered interventions targeting informal ND-caregivers. However, more rigorous studies, with longer follow-ups across outcomes and involving NDs other than dementia, are imperative to enhance the knowledge-base.

Family Carers of People with Dementia in Japan, Spain, and the UK: A Cross-Cultural Comparison of the Relationships between Experiential Avoidance, Cognitive Fusion, and Carer Depression

Objective and research design This study investigated whether the relationship between experiential avoidance and carer depression is mediated by cognitive fusion using path analysis and whether this model differs between family carers from Japan, Spain, and the UK using multi-group path analysis. Results The whole sample model (N = 745) showed a good fit to the data. The direct effect of experiential avoidance on carer depression (β = .10) and its indirect effect on carer depression through cognitive fusion (β = .15) were significant. Examined variables accounted for 45% of the variance of depression. Multi-group path analysis confirmed the same pattern of indirect path across 3 countries, while the direct path was no longer significant in Spanish and UK samples.Conclusion These findings suggest that targeting cognitive fusion may be particularly critical in culturally diverse carers and pre-emptive efforts to reduce experiential avoidance using psychological techniques may be beneficial among family carers prone to cognitive fusion regardless of cultural differences.

Therapists’ perceptions and acceptability of providing internet-delivered guided self-help acceptance and commitment therapy (ACT) for family carers of people with dementia (iACT4CARERS): a qualitative study

This study aimed to explore therapists’ perceptions and acceptability of providing internet-delivered, therapist-guided, self-help acceptance and commitment therapy (ACT) for family carers of people with dementia (iACT4CARERS). To achieve this, a qualitative approach with semi-structured interviews was employed with eight novice therapists recruited from primary and secondary care services taking part in a feasibility study of iACT4CARERS. The interviews were audio-recorded, transcribed, and analysed using thematic analysis. Four over-arching themes were identified: (1) positive attitudes towards the intervention, (2) therapists’ workload, (3) therapists’ confidence to perform their role, and (4) connecting with family carers in a virtual context. Theme 1 included seeing their involvement as an opportunity for personal growth and perceiving benefits to the family carers, which contributed to greater acceptability. Theme 2 reflected that while workload and the user-friendliness of the online platform were highly acceptable among the therapists, there were also time-consuming cases that increased therapists’ burden. Theme 3 revealed that practical resources provided during the training, continued supervision, and opportunities to learn from other therapists, increased therapist confidence and facilitated greater acceptability. Finally, Theme 4 highlighted that improving the connection between therapists and carers was critical in a virtual context and strategies to improve the therapist–carer relationship were recommended. The implementation of iACT4CARERS was largely acceptable for the therapists involved in the trial. Ways to strengthen the therapeutic relationship in the virtual context and practical strategies to deal with common problems may enhance therapist experience and delivery in a full-scale effectiveness trial.

A Model of the Effects of Parental Illness on Youth Adjustment and Family Functioning: The Moderating Effects of Psychological Flexibility on Youth Caregiving and Stress

Parental chronic illness may adversely impact youth and family functioning. This study examined a moderated mediation model of the effects of parental illness on youth and family functioning derived from the Family Ecology Framework. Consistent with this model, we predicted that youth caregiving and stress would serially mediate the adverse impacts of parental illness on youth adjustment and family functioning and that psychological flexibility would moderate these mediational mechanisms. A total of 387 youth, with parents affected by chronic illness, completed a questionnaire assessing parental illness severity, youth caregiving and stress, psychological flexibility, youth adjustment (i.e., internalizing and externalizing problems and psychological wellbeing), and family functioning. Path analyses indicated that the adverse effects of parental illness on youth adjustment and family functioning were serially mediated by youth caregiving and stress. Psychological flexibility buffered the adverse effects of these serial mediators on youth internalizing problems and psychological wellbeing. These findings identified three potential intervention targets: youth caregiving, related stress appraisals, and psychological flexibility. Given the large body of evidence showing that acceptance and commitment therapy fosters psychological flexibility, this intervention approach has the potential to address the psychosocial and mental health vulnerabilities of youth in the context of parental illness, which constitutes a serious public health issue.
