The HADS (Hospital Anxiety and Depression Scale) aims to measure symptoms of anxiety (HADS Anxiety) and depression (HADS Depression). The HADS is widely used but has shown ambiguous results both regarding the factor structure and sex differences in the prevalence of depressive symptoms. There is also a lack of psychometric evaluations of the HADS in non-clinical samples of older people. The aim of the study was to evaluate the factor structure of the HADS in a general population 65–80 years old and to exam possible presence of differential item functioning (DIF) with respect to sex. This study was based on data from a Swedish sample, randomized from the total population in the age group 65–80 years (n = 6659). Confirmatory factor analyses (CFA) were performed to examine the factor structure. Ordinal regression analyses were conducted to detect DIF for sex. Reliability was examined by both ordinal as well as traditional Cronbach’s alpha. The CFA showed a two-factor model with cross-loadings for two items (7 and 8) had excellent model fit. Internal consistency was good in both subscales, measured with ordinal and traditional alpha. Floor effects were presented for all items. No indication for meaningful DIF regarding sex was found for any of the subscales. HADS Anxiety and HADS Depression are unidimensional measures with acceptable internal consistency and are invariant with regard to sex. Despite pronounced ceiling effects and cross-loadings for item 7 and 8, the hypothesized two-factor model of HADS can be recommended to assess psychological distress among a general population 65–80 years old.

Background: Social support is generally known to influence health-related quality of life (HRQoL), but this association is not well explored among older patients with chronic heart failure. Aims: (1) To describe social support in older patients with chronic heart failure in relation to gender. (2) To investigate if age, gender, cohabitation, perceived financial situation, and disease severity are associated with social support. (3) To investigate if social support is associated with HRQoL after controlling for age, gender, and disease severity. Methods: Data were collected in a sample of 349 patients (≥65 years) with chronic heart failure. Patients’ HRQoL was measured with the Minnesota Living with Heart Failure Questionnaire and the Short Form-12 Health Survey Questionnaire. The Interview Schedule for Social Interaction measured social support. Data were analysed with descriptive statistics, repeated-measure ANOVA, and multiple linear regression analyses with robust standard errors. Results: Social support was generally rated high, although being a man, living alone, perceiving a problematic financial situation, and high disease severity (NYHA) were associated with lower levels of social support. Age was not associated with social support. Social support was generally associated with HRQoL, in particular the emotional dimensions. Conclusion: Taking social support into account when caring for older patients with heart failure can be of importance for improving or maintaining HRQoL.

In palliative care, family caregivers are often faced with experiences of grief in anticipation of the loss of a close person. An instrument designed to measure this form of grief is the Anticipatory Grief Scale, which includes 27 items and has been used in several studies in various contexts. However, the instrument has not been validated. The aim was to evaluate the psychometric properties, focusing on the factor structure, of the Anticipatory Grief Scale in a sample of family caregivers in palliative care. The study had a cross-sectional design. Data were collected from an intervention study in palliative home care that took place between 2013 and 2014. In total, 270 family caregivers in palliative care completed a baseline questionnaire, including the Anticipatory Grief Scale. The factor structure of the scale was evaluated using exploratory factor analysis. The initial factor analysis suggested a four-factor solution, but, due to weak communalities, extensive crossloadings, and item inconsistencies, the model was problematic. Further analysis supported that the scale should be reduced to 13 items and two factors. The two subscales captured the behavioral and emotional reactions of grief in family caregivers in palliative care and were named Behavioral reactions and Emotional reactions. This modified version will hereafter be named AGS-13. This validation study of the Anticipatory Grief Scale resulted in a revised two-factor model, AGS-13, that appears to be promising for use in palliative care but needs to be tested further.

To describe burden and health-related quality of life amongst caregivers of out-of-hospital cardiac arrest survivors and explore the potential association with cognitive function of the survivors. Caregivers of patients with ST-elevation myocardial infarction were used as controls. Data were collected from the cognitive substudy of the Targeted Temperature Management-trial. Caregiver burden was assessed with the 22-item Zarit Burden Interview, with scores ≤20 considered as no burden. Health-related quality of life was assessed with the SF-36v2®, with T-scores 47-53 representing the norm. Cardiac arrest survivors were categorized based on the results from cognitive assessments as having "no cognitive impairment" or "cognitive impairment". Follow-up 6 months post event was performed for caregivers of 272 cardiac arrest survivors and 108 matched myocardial infarction controls, included at an intended ratio of 2:1. In general, caregivers of cardiac arrest survivors and controls reported similar caregiver burden. The overall scores for quality of life were within normative levels and similar for caregivers of cardiac arrest survivors and control patients. Compared to those with no cognitive impairment, caregivers of cognitively impaired cardiac arrest survivors (n = 126) reported higher levels of burden (median 18 versus 8, p < 0.001) and worse quality of life in five of eight domains, particularly "Role-Emotional" (mean 45.7 versus 49.5, p = 0.002). In general, caregivers of cardiac arrest survivors and myocardial infarction controls reported similar levels of burden and quality of life. Cognitive outcome and functional dependency of the cardiac arrest survivor impact burden and quality of life of the caregiver.
