Caring for a relative with dementia is associated with negative psychological consequences for the caregivers, such as depression. Cognitive fusion is considered a key process of psychological inflexibility, associated with psychological distress. The aim of this study is to analyze whether baseline levels of cognitive fusion predict different treatment response of depressive symptoms, comparing individual Acceptance and Commitment Therapy (ACT), Cognitive and Behavioral Therapy (CBT) interventions and a control group. A total of 130 family caregivers participated in the study: ACT intervention (N = 49), CBT intervention (N = 41) and control group (N = 40). Moderation analyses were conducted. The results show a significant effect of the interaction between baseline levels of cognitive fusion and the treatment condition (p < .05) on depressive symptoms. Specifically, caregivers in the CBT condition presented higher change in depressive symptoms than those in the control group when their baseline levels of cognitive fusion were low, medium and high. Participants in the ACT condition showed a greater change in depressive symptoms than participants in the control group when their baseline levels of cognitive fusion were medium and high. Finally, the findings suggest that caregivers in the ACT condition showed a greater change in depressive symptoms than those in the CBT condition when their baseline levels of cognitive fusion were high. These results seem to support the use of cognitive fusion as a screening tool for intervention assignment in clinical practice with dementia caregivers.

Background The world prevalence of people with dementia is increasing. Most of the care received by people with dementia is provided by family caregivers, and this prolonged activity has a significant impact on caregivers' levels of depression. Stressors and frequency of leisure are known predictors of caregivers' depressive levels. The longitudinal impact of caregivers' ambivalent and guilt feelings is unknown. Methods Participants were 177 family caregivers of relatives with dementia who were assessed three times during a 2-year period. In addition to demographic variables, psychological symptoms of the dementias, and frequency of leisure activities, caregivers' ambivalent feelings, guilt, and depressive symptoms were measured. The longitudinal association of changes in these variables with changes in caregivers' depressive symptoms over time was assessed using mixed linear models. Results Changes over time in the assessed variables predicted 48.05% of variance of changes over time in depressive symptoms. Even when variables strongly associated with increased depressive symptoms were controlled (lower caregivers' age and educational level, higher reaction to BPSD, and lower leisure activities), increases in ambivalence and guilt contributed to an increase of 9.22% of the variance of changes depressive symptoms over a 2-year period. The effects of ambivalent feelings on depression are indirect, mediated by guilt feelings. Cessation of caregiving do not seem to alter these findings. Conclusions Caregivers' ambivalent and guilt feelings are significant predictors of caregivers' mental health. Caregivers may significantly benefit from early detection of ambivalent and guilt feelings and preventive strategies targeting triggers associated with ambivalent and guilt symptoms
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
(Taylor and Francis - Revista Agind and Mental Health, 2021-06-13) Cabrera, Isabel; Márquez-González, María; Gallego-Alberto, Laura; del Sequeros Pedroso-Chaparro, María; Barrera-Caballero, Samara; Losada, Andrés
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.
