Abstract: BACKGROUND: Caregiving for people with dementia has consistently been linked with psychological problems, usually in terms of caregiver burden, general psychological distress and depressive symptomatology, while morbidity due to anxiety has been relatively neglected in this group. METHODS: We conducted a systematic review of the literature, searching electronic databases, reference lists, relevant systematic reviews and contacting experts in the field. We used Centre for Evidence Based Medicine (CEBM) criteria for inclusion and rating the validity of all studies that reported (1) the prevalence, predictors and covariates of anxiety disorders or anxiety caseness, and (2) covariates and predictors of the level of anxiety symptoms. RESULTS: Thirty-three studies met our inclusion criteria. Clinically, significant anxiety affects about a quarter of caregivers for people with dementia and was more common than in matched controls. Such caregivers have higher anxiety levels than controls, and that confrontative and escape avoidance coping, caregiver burden and poorer caregiver physical health are factors associated with higher anxiety levels from cross-sectional studies. CONCLUSIONS: Coping style may be more associated with anxiety than depression while other covariates (burden and poor physical health) are similar to those for caregiver depression. We found no conclusive evidence about factors associated with anxiety disorders or predicting anxiety from longitudinal studies. Neither care recipient cognition nor ADL impairment; nor caregiver age nor duration of caring are associated with caregiver anxiety levels. Good quality cohort studies are needed to determine whether these factors also predict anxiety disorders.

Abstract: OBJECTIVES: The frequent comorbidity of panic and affective disorders has been described in previous studies. However, it is not clear how panic disorder comorbidity in unipolar disorder and bipolar disorder is related to illness course. METHODS: We compared lifetime clinical characteristics of illness and items of symptomatology in samples of individuals with bipolar I disorder (n = 290) and unipolar disorder (n = 335) according to the lifetime presence of recurrent panic attacks. RESULTS: We found significant differences in clinical course of illness characteristics that were shared across the unipolar and bipolar samples according to the lifetime presence of panic attacks. We also found a number of differences according to the presence of panic attacks that may be specific to the diagnostic group. CONCLUSIONS: Distinguishing patients who have mood disorder diagnoses, especially bipolar I disorder, according to the lifetime presence of panic attacks may not only be of use in clinical practice, but may also be informative for aetiological research, such as molecular genetic studies.

Abstract: OBJECTIVES: There have been few longitudinal studies investigating the impact of coping on psychological morbidity in caregivers of people with dementia. Findings have been inconsistent and little attention has been paid to anxiety in caregivers. We explored the hypothesis that the relationship between caregiver burden and anxiety and depression is mediated by coping style. METHODS: As part of the LASER-AD study, 93 (73.8%) people with Alzheimer's disease and their family caregivers recruited at baseline were re-interviewed 1 year later. Sampling aimed to ensure that the participants were representative of people living in the UK with Alzheimer's disease in terms of dementia severity, gender and care setting. We used the Hospital Anxiety and Depression Scale, the Zarit Burden scale and the Brief COPE to measure coping strategies. RESULTS: Using fewer emotion-focused strategies and more problem-focused strategies (but not dysfunctional strategies) mediated the relationship between caregiver burden and anxiety a year later, after controlling for potential confounders, in a well-fitting structural equation model (chi(2)=0.93, df=3, p=0.82; NFI=1.0, RFI=0.97, IFI=1.0, TLI=1.1, RMSEA=0.0). Using fewer emotion focused strategies also predicted higher psychological morbidity in general. The hypothesised relationship was not proved for depression. CONCLUSIONS: Using emotion-focussed coping strategies in response to caregiver burden seemed to protect caregivers from developing higher anxiety levels a year later; however using problem-focussed strategies did not. Our results suggest that a psychological intervention package to emphasise emotion-focused coping may be a rational approach to reduce anxiety in dementia caregivers. Studies are needed to test such interventions.

Abstract: BACKGROUND: Preliminary evidence indicates that the quality of the carer-care recipient relationship predicts those carers most at risk from anxiety. Attachment style is related to higher carer burden, psychological morbidity and increased care recipient institutionalization. We tested, for the first time, the hypothesis that carer burden and the coping strategies used mediate a relationship between attachment style and anxiety. METHODS: We interviewed 83 people with Alzheimer's disease and their family carers, originally recruited for a larger community study. Carers filled in a validated measure about their attachment style, the Hospital Anxiety and Depression Scale, the COPE to measure coping strategies, and the Zarit-Burden interview. RESULTS: More avoidant attachment (beta = 0.28) and less secure attachment (beta = -0.32) predicted anxiety. After adding coping strategies to the equation, the relationship with avoidant attachment (beta = 0.15) was no longer significant, and that with less secure attachment was reduced (beta = -0.23). A well-fitting structural equation model supported our finding that dysfunctional coping mediated the relationship between attachment style and anxiety. CONCLUSION: Carers who were less secure or more avoidantly attached reported higher anxiety. Interventions that aim to modify coping strategies have shown promise in reducing carer anxiety. Our finding that coping strategies also appear partially to explain the excess of anxiety among less securely attached carers suggests they are likely to benefit from such interventions.

Abstract: BACKGROUND: Caregivers of people with dementia (CGPD) frequently have anxiety symptoms but little is known about the relationship of anxiety with coping strategies. METHOD: 126 people with Alzheimer's disease (AD) and their family caregivers living in the community were recruited from local psychiatric services, the voluntary sector and care homes. Sampling was designed to ensure that the sample was epidemiologically representative in terms of dementia severity, gender and care setting. We used the anxiety subscale of the Hospital Anxiety and Depression Scale (HADS) to measure anxiety and the Brief COPE to measure coping strategies. RESULTS: Use of dysfunctional coping strategies (Wald = 7.3, p = 0.007) and HADS depression caseness (Wald = 14.0, p < 0.001) were the only factors that predicted HADS anxiety caseness on logistic regression. LIMITATIONS: Anxious caregivers may be more likely to report their coping strategies negatively; these results do not clarify direction of causality. CONCLUSIONS: Dysfunctional coping strategies and depression appear to be the most important factors predicting caregiver anxiety. Addressing coping strategies may be a helpful intervention for managing caregiver anxiety.
