Increases in utilization of psychosocial resources mediate effects of cognitive-behavioural intervention on dementia caregivers’ quality of life

Between- and within-person effects of affective experiences on coping in CBT: Direct effects and interplay with therapeutic alliance and resource activation

OBJECTIVE

The role of affective experiences (AE) in cognitive-behavioral therapy (CBT) has rarely been investigated. We examined between- and within-person effects of AE on coping in CBT for family caregivers and interactions with therapeutic alliance and resource activation.

METHODS

67 family caregivers rated AE, therapeutic alliance, resource activation, and coping after each of 12 sessions of telephone-based CBT. We examined direct session-to-session effects of AE on coping in structural equation modeling and interactions of AE with therapeutic alliance and resource activation in multilevel models.

RESULTS

AE did not directly predict coping. Instead, within-person effects of AE interacted with simultaneous within-person emotional bond. Given strong emotional bond, AE positively predicted coping, whereas given weak emotional bond, AE negatively predicted coping. Further, cross-level interactions of between-person AE and within-person agreement on collaboration and resource activation indicated that these positively predicted coping only in dyads with high between-person AE.

CONCLUSION

AE may enhance coping when complemented with strong emotional bond. Further, within-person effects of agreement on collaboration and resource activation seem to rely on a certain degree of between-person AE. Results are discussed in relation to current findings on emotional processing in CBT.

Face-to-face versus telephone-based cognitive-behavioral therapy for family caregivers of people with dementia

OBJECTIVE

The objective was to directly compare the effects and acceptability of telephone-based (TEL-CBT) with face-to-face cognitive-behavioral therapy (F2F-CBT) for family caregivers of people with dementia (PwD).

METHOD

Caregivers for whom F2F participation was possible were allocated to F2F-CBT (n = 49). The other participants were randomized to TEL-CBT (n = 139) or CG (n = 134). CBT consisted of 12 sessions over 6 months.

RESULTS

TEL-CBT yielded significantly better physical health (d = 0.27) and coping with daily hassles (d = 0.38) at posttest compared to F2F-CBT. Therapist competence, acceptability, and outcomes at follow-up did not differ between TEL-CBT and F2F-CBT.

CONCLUSIONS

TEL-CBT is a valuable alternative to F2F-CBT for family caregivers of PwD as TEL-CBT has the advantage of higher accessibility while it does not significantly differ from F2F-CBT in effectiveness and caregivers' evaluation of the setting, their experience with the therapist, and their satisfaction.

Effects of general change mechanisms on outcome in telephone-based cognitive-behavioral therapy for distressed family caregivers

BACKGROUND

The study investigated the influence of general change mechanisms (GCMs) on outcome in telephone-based cognitive-behavioral therapy (CBT) for family caregivers.

METHODS

In a stepped-care intervention approach, highly distressed family caregivers received telephone-based CBT after completing a care counseling intervention. Sixty-six therapist-caregiver dyads rated emotional bond, agreement on collaboration, problem actuation, resource activation, clarification of meaning, and mastery after each of 12 therapy sessions. Outcomes were caregiver burden (SCQ-AV) and depression (CES-D) after therapy. Associations of GCMs with outcome were examined in multilevel regression models.

RESULTS

Caregiver burden was significantly predicted by caregiver-rated emotional bond (β = -0.18) as well as therapist-rated resource activation (β = -0.26), problem actuation (β = -0.22), clarification of meaning (β = -0.18), and mastery (β = -0.18). None of the GCMs predicted depression from any perspective.

CONCLUSION

The findings suggest that GCMs are relevant for reducing caregiver burden in CBT for family caregivers and should be fostered in treatment manuals, in particular therapist-rated GCMs. Since therapist and caregiver perspectives differed in predicting caregiver burden, future research should investigate perspective congruence and its effect on therapy outcome.

Effects of nursing home placement on the mental health trajectories of family caregivers of people with dementia: findings from the Tele.TAnDem intervention study

OBJECTIVES

The objective was to compare mental health trajectories between family caregivers of people with dementia (PwD) who institutionalize the care recipient (nursing home caregivers [NHC]) and caregivers who continue to provide care at home (at-home caregivers [AHC]) as well as investigate effects of a telephone-based cognitive-behavioral therapy (TEL-CBT) intervention on these trajectories.

METHODS

Using linear growth models, we compared the trajectories of depressive symptoms, caregiver grief, anxiety, and quality of life (QoL) over one year (baseline - T0, 6 months - T1, and 12 months - T2) between 28 NHC and 163 AHC who had been randomized to receive 12 sessions of TEL-CBT (n = 99) or to usual care (n = 92).

RESULTS

NHC reported significantly higher depression, anxiety, and caregiver grief at T0 and showed significant reductions in depression and anxiety over time compared to AHC. TEL-CBT significantly enhanced overall QoL of NHC.

CONCLUSIONS

The study extends previous findings of improved mental health of family caregivers of PwD after institutionalization and emphasizes the need for interventions before nursing home placement. TEL-CBT which has previously been shown to be effective for family caregivers of PwD also seems promising for supporting NHC.

Pragmatic Effectiveness of Face-to-Face Cognitive-Behavioral Therapy for Family Caregivers of People with Dementia

OBJECTIVES

The objective was to investigate the pragmatic effectiveness of face-to-face cognitive-behavioral therapy (F2F-CBT) for family caregivers of people with dementia (PwD) implemented in a routine care setting relative to usual care in a quasi-experimental study.

METHODS

Participants indicating that attendance of F2F-CBT was possible were assigned to F2F-CBT (n = 49). F2F-CBT consisted of 12 sessions over 6 months. Effects were evaluated at posttest and 6-month follow-up on a variety of outcomes relative to usual care (CG; n = 134).

RESULTS

At posttest, F2F-CBT yielded significantly fewer symptoms of depression (d = 0.37), better emotional well-being (d = 0.64), and better coping with the care situation (d = 0.52) than CG. At 6-month follow-up, the effect on emotional well-being was retained (d = 0.44) and social relationships were rated significantly better in F2F-CBT than CG (d = 0.34).

CONCLUSIONS

F2F-CBT proved to be effective in supporting family caregivers of PwD. However, only relatively few caregivers were able to regularly attend face-to-face sessions.

CLINICAL IMPLICATIONS

CBT seems particularly suitable for supporting family caregivers of PwD in coping with the complex psychological burden. Delivery via telephone or internet could be a necessary alternative to F2F-CBT for reducing barriers to participation.

Clients' and therapists' experiences of five general change mechanisms during an Internet-based cognitive behavioral intervention for family caregivers

OBJECTIVES

Despite its efficacy, little is known about what makes Internet-based cognitive behavioral therapy (iCBT) effective. We, therefore, analyze participants' and therapists' experiences of Grawe's five general change mechanisms (alliance, resource activation, clarification, problem actuation, mastery) during an iCBT intervention for family dementia caregivers, and how their experiences were related to treatment outcomes.

METHOD

Participants (N = 30) exchanged eight weekly messages with a therapist via an Internet platform. We used the Bern Post Session Report to assess participants' and therapists' experiences of the general change mechanisms after each session.

RESULTS

Treatment outcomes were associated with therapists' overall experiences of alliance, clarification, and mastery. Participants experienced more problem actuation than therapists. Only participants' and therapists' experiences of clarification over time differed.

CONCLUSIONS

Grawe's general change mechanisms are also relevant for iCBT. We recommend considering Grawe's framework when designing Internet-based therapeutic interventions and when training therapists to deliver such interventions.

Relieving distressed caregivers (ReDiCare study): study protocol of a randomized pragmatic trial

BACKGROUND

Providing care for someone with a disease or chronic condition can have a negative psychological, physical, social, and economic impact upon informal caregivers. Despite the socio-economic relevance and more than three decades of caregiver intervention research only very few translational efforts of successful interventions are reported. Still less of these interventions have been implemented into routine services. The aim of the ReDiCare study (German acronym BerTA) is to evaluate the effectiveness of a stepped counselling approach for burdened caregivers delivered by care counsellors of two long-term care insurances and registered psychotherapists.

METHODS/ DESIGN

A pragmatic randomised controlled trial with 572 caregivers of older adults (≥ 60 years) receiving benefits of one of the two participating long-term care insurances. Participants are assigned (t0) to either the ReDiCare intervention or a control group receiving routine care and counselling. Data are collected at baseline (-t1), 3-month (t1), 9-month (t2) and 15-month (t3). The 9-month post-intervention assessment (t2) is the primary endpoint to evaluate the results on the primary and secondary outcomes, measured by self-reported questionnaires. Depressive symptoms measured with the CES-D are the primary outcome. The main secondary outcomes are physical complaints, utilization of psychosocial resources, caregiver self-efficacy and burden, positive aspects of caregiving and perceived care quality. A process evaluation, including audio tapes, self-report questionnaires and documentation will be conducted to examine internal and external validity of the intervention. Data on direct and indirect costs are collected for the (health) economic evaluation, using a health care perspective and a societal perspective.

DISCUSSION

While comparable previous caregiver interventions have been developed and evaluated for specific caregiver groups (e.g. dementia caregivers, stroke caregivers), the ReDiCare study will indicate whether a stepped approach will be effective also in a broader group of caregivers. The intervention is one of the very few translational studies in caregiver intervention research and will provide valuable insights into relevant factors for training, intervention protocol adherence, effectiveness, and costs for future implementation steps.

Long-Term Effects of a Cognitive Behavioral Conference Call Intervention on Depression in Non-Professional Caregivers

Recent evidence supports the efficacy of conference call cognitive-behavioral interventions in preventing depression in caregivers at post-intervention, but we do not know whether the results are sustained long term. The main objective of this study was to evaluate the long-term efficacy of a cognitive-behavioral intervention administered by telephone conference call in preventing depression in caregivers with elevated depressive symptoms, comparing all components of the intervention versus only the behavioral ones. A randomized controlled trial was conducted using a dismantling strategy. At total of 219 caregivers were randomly assigned to a cognitive-behavioral conference call intervention (CBCC; n = 69), a behavioral-activation conference call intervention (BACC; n = 70), or a usual care control group (CG, n = 80). Information was collected on depressive symptoms and depression at pre-intervention and at 1, 3, 6, 12, and 36 months post-intervention. At 36 months, there was a reduction in depressive symptoms (p < 0.001) and a lower incidence of major depressive episodes in both the CBCC and BACC groups compared to CG (8.7%, 8.6%, and 33.7%, respectively). The results show that a conference call intervention was effective in the long term to prevent depression in caregivers and that the behavioral-activation component was comparable to the complete cognitive-behavioral protocol.
