How do care-related beliefs contribute to depression and anxiety in family caregivers of people with dementia? Testing a cognitive vulnerability-stress model.

OBJECTIVES: Care-related beliefs are considered risk factors for decreased mental health in family caregivers of people with dementia. However, their exact role in the caregiver stress process remains unclear. Hence, we tested a cognitive vulnerability-stress model of depression and anxiety in family caregivers of people with dementia. METHOD: A cross-sectional study was conducted using baseline data from a caregiver intervention trial (N = 322). Within Bayesian moderated mediation analysis, we examined mediation of effects of objective demands (severity of dementia, challenging behavior, caregiving intensity, caregiving duration) on depression and anxiety via subjective caregiver burden and moderation by care-related beliefs in four domains (dysfunctional caregiving standards, dysfunctional attitudes towards dementia, functional self-care-related beliefs, functional acceptance-related beliefs). RESULTS: The relation between objective demands and subjective burden was amplified by dysfunctional caregiving standards and dysfunctional attitudes towards dementia and mitigated by functional self-care-related beliefs. Further, functional acceptance-related beliefs attenuated the effect of subjective caregiver burden on depression. CONCLUSION: The study provides preliminary evidence for a cognitive vulnerability-stress model of depression and anxiety in family caregivers of people with dementia. The results indicate that the four-domain model of care-related beliefs is a valuable framework for future research and may serve as a heuristic model for cognitive-behavioral therapy in this population.

Love yourself as a therapist, doubt yourself as an institution? Therapist and institution effects on outcome, treatment length, and dropout.

OBJECTIVE: Research suggests that some therapists achieve better outcomes than others. However, an overlooked area of study is how institution differences impact patient outcomes independent of therapist variance. This study aimed to examine the role of institution and therapist differences in adult outpatient psychotherapy. METHOD: The study included 1428 patients who were treated by 196 therapists at 10 clinics. Two- and three-level hierarchical linear regression models were employed to investigate the effects of therapists and institutions on three dependent patient variables: (1) symptom change, (2) treatment duration, and (3) dropout. Level three explanatory variables were tested. RESULTS: The results showed that therapist effects (TE) were significant for all three types of treatment outcome (7.8%-18.2%). When a third level (institution) was added to the model, the differences between therapists decreased, and significant institution effects (IE) were found: 6.3% for symptom change, 10.6% for treatment duration, and 6.5% for dropout. The exploratory analyses found no predictors able to explain the systematic variation at the institution level. DISCUSSION: TE on psychotherapy outcomes remain a relevant factor but may have been overestimated in previous studies due to not properly distinguishing them from differences at the institution level.

Telephone-Based Acceptance and Commitment Therapy for Caregivers of Persons with Dementia: Results of a Randomized Controlled Trial.

OBJECTIVES: Family caregivers of persons with dementia (PwD) experience high levels of distress. We used a randomized-controlled trial to investigate the effects of telephone-based acceptance and commitment therapy (tbACT) for family caregivers. METHODS: Caregivers were randomly allocated to an intervention group (tbACT, n = 41) or an untreated control group (CG, n = 40). The intervention consisted of eight weekly sessions of tbACT. Depression and anxiety (primary outcomes), physical symptoms, pre-death grief, care-related thoughts, acceptance (secondary outcomes), quality of life, coping and well-being (well-being/coping outcomes) were assessed pre- and post-assessment. A 6-month follow-up was conducted. RESULTS: Compared to CG participants, tbACT participants had at post-assessment significantly lower depressive symptoms; fewer physical symptoms (rheumatic pain); better physical health; more resource utilization (coping with daily hassles, social support); better coping with the care situation and better emotional well-being. During the six-month follow-up, tbACT participants showed less pre-death grief, fewer physical symptoms, and more utilization of resources related to coping with daily hassles. CONCLUSIONS: tbACT is a feasible and promising psychotherapeutic intervention for family caregivers of PwD. Because of small sample size our results are preliminary. CLINICAL IMPLICATIONS: Most of the effects of tbACT were not maintained 6 months after the intervention, suggesting that booster sessions may be helpful.

The Caregiver Thoughts Scale: An Instrument to Assess Functional and Dysfunctional Thoughts about Caregiving.

OBJECTIVES: Caregivers' care-related thoughts critically effect their well-being. Currently, there is a lack of validated measures to systematically assess caregivers' functional and dysfunctional thoughts. We therefore aimed to develop a measure of caregivers' thoughts that assesses not only their dysfunctional but also their functional thoughts in multiple domains. METHODS: A pool of potential questionnaire items was generated from therapy sessions with caregivers and was rated by experts. A sample of 322 main family caregivers (Mage = 63.9 years) of a person with dementia then completed a set of 28 items about their care-related thoughts and a number of related measures at three measurement points. Items were then aggregated via a formative measurement approach based on theoretical considerations. Correlational analyses were used to examine the construct validity of the subscale scores. RESULTS: The final 28-item scale assesses caregiving thoughts in four distinct domains: dysfunctional caregiving standards, self-care, dysfunctional assumptions about dementia, and acceptance. The correlational analyses demonstrated the subscales' construct validity, by showing that scale scores are meaningfully related to theoretically relevant constructs. CONCLUSIONS: The Caregiving Thoughts Scale is a promising measure of caregivers' thoughts in four important domains. CLINICAL IMPLICATIONS: The scale can be applied in clinical research settings.

Somatic distress among Kosovar civilian war survivors: relationship to trauma exposure and the mediating role of experiential avoidance.

PURPOSE: The current study examined the prevalence and correlates of somatic distress (SD) in the aftermath of war, and the role of a process hypothesized to contribute to posttraumatic stress: experiential avoidance. METHODS: Civilian war survivors (n = 163) from Kosovo were assessed in structured interviews, reporting on average more than ten types of traumatic war exposure. RESULTS: One in eight (12.9%) of the participants meet criteria for SD, which was associated with greater psychological distress, experiential avoidance, and lower quality of life after accounting for the effects of war-related variables, demographic variables, as well as posttraumatic stress disorder and major depressive episode. Experiential avoidance partially mediated the association between SD and psychological distress and quality of life. CONCLUSIONS: The results indicate that SD is prevalent among war-exposed civilians and that experiential avoidance may be a significant factor in understanding and treating traumatized people who are experiencing SD.

Maintenance cognitive-behavioral therapy and manualized psychoeducation in the treatment of recurrent depression: a multicenter prospective randomized controlled trial.

OBJECTIVE: This multicenter study compared the relapse and recurrence outcomes of two active treatments, maintenance cognitive-behavioral therapy (CBT) and manualized psychoeducation, both in addition to treatment as usual, in patients in remission from depression. METHOD: This was a multicenter prospective randomized observer-blinded study with two parallel groups. The authors assessed 180 patients with three or more previous major depressive episodes who met remission criteria over a 2-month baseline period and who were randomly assigned to 16 sessions of either maintenance CBT or manualized psychoeducation over 8 months and then followed up for 12 months. The main outcome measure was time to first relapse or recurrence of a major depression, based on DSM-IV criteria, as assessed by blinded observers with the Longitudinal Interval Follow-Up Evaluation. RESULTS: Cox regression analysis showed that time to relapse or recurrence of major depression did not differ significantly between treatment conditions, but a significant interaction was observed between treatment condition and number of previous episodes (<5 or ≥5). Within the subsample of patients with five or more previous episodes, maintenance CBT was significantly superior to manualized psychoeducation, whereas for patients with fewer than five previous episodes, no significant treatment differences were observed in time to relapse or recurrence. CONCLUSIONS: The results indicate that maintenance CBT has significant effects on the prevention of relapse or recurrence only in patients with a high risk of depression recurrence. For patients with a moderate risk of recurrence, nonspecific effects and structured patient education may be equally effective.
