Major depression in older medical inpatients is frequent, persistent, and disabling (Cole and Bellavance, 1997). The incidence is 20.5%–30.2% during the 12 months following admission to hospital (Fenton et al., 1997; Cole et al., 2008). Up to 73% of patients have a protracted course (Koenig et al., 1992; Cole et al., 2006; Koenig, 2006). Moreover, major depression in older medical inpatients appears to be associated with decreased function (Covinsky et al., 1997), increased use of health care services (Koenig et al., 1989; Büla et al., 2001), increased caregiver burden (McCusker et al., 2007), and possibly increased mortality (Cole, 2007).

Background: Accurate measures of mood state are important for understanding and optimizing health and well-being in later life. A range of different mood assessment measures is available, reflecting the variety of ways in which mood has been conceptualized and the different purposes for which measures have been developed.

Methods: We undertook a conceptual review of the literature relating to mood and its assessment in older populations.

Results: Moods are subjective states of mind that are typically described and quantified using self-report measures. Moods can be conceptually differentiated from the related psychological concepts of emotion, well-being, quality of life, and depression. Quantitative tools for assessing mood state include single-item mood ratings, composite factor scales, and clinical depression assessments. Mood assessments may be administered retrospectively or contemporaneously to the mood state of interest. The method and temporal perspective used to assess mood state will impact on the nature and precision of the mood data that are collected, and the types of research questions that can be addressed.

Conclusions: No single mood assessment technique can be considered optimal for all situations. Rather, both the type of tool and the temporal perspective taken must be selected according to the nature of the study design and the research question being addressed. More thorough and frank reporting of the rationale for, and limitations of, mood assessment techniques are also essential for continued development of mood research with older adults.

Background: There is growing evidence that neighborhood environments are related to depressive mood in the general population. Older adults may be even more vulnerable to neighborhood factors than other adults. The aim of this paper is to review empirical findings on the relationships between neighborhood characteristics and depressive mood among older adults.

Methods: A search of the literature was undertaken in PsycINFO and MEDLINE.

Results: Nineteen studies were identified. Study designs were most often cross-sectional, included large sample sizes, and controlled for major individual characteristics. Mediational effects were not investigated. Statistical analysis strategies often included multilevel models. Spatial delimitations of neighborhood of residence were usually based on administrative and statistical spatial boundaries. Six neighborhood characteristics were assessed most often: neighborhood socioeconomic disadvantage, neighborhood poverty, affluence, racial/ethnic composition, residential stability, and elderly concentration. Selected neighborhood characteristics were associated with depressive mood after adjusting for individual variables. These associations were generally theoretically meaningful.

Conclusions: Neighborhood variables seem to make a unique and significant contribution to the understanding of depressive mood among older adults. However, few studies investigated these associations and replication of results is needed. Several substantive neighborhood variables have been ignored or neglected in the literature. The implications of neighborhood effects for knowledge advancement and public health interventions remain unclear. Recommendations for future research are discussed.

Background: The aim of the current study was to investigate the associations between family characteristics and depressive symptoms, and provide new evidence and recommendations for prevention and intervention in the depressive symptoms of older adults.

Methods: The study was a cross-sectional survey conducted door-to-door, utilizing a sample of 1,317 individuals aged 60 years and above in rural China. The five family characteristic variables recorded were: living with spouse, living with descendant, support of family members, self-reported family economic status in the previous year, and family-related negative life events that occurred anytime in the past with a continuous psychological effect during the past 12 months. Gender, age, years of schooling, and self-rated physical health status were taken as potential confounders. Univariable and multivariable logistic regression models were used to examine independent effects on depressive symptoms.

Results: In addition to the potential confounders, only family-related negative life events, support of family members, and self-reported family economic status had significant effects on depressive symptoms in older adults. Experiencing a family-related negative life event was the most significant variable (OR = 11.70, 95% CI: 7.72–17.73), the second was support of family members (OR = 6.93, 95% CI: 3.26–14.70), while family economic status was less important than support of family members (OR = 2.38, 95% CI: 1.08–5.25).

Conclusion: This study, from the perspective of family characteristics on depressive symptoms in older adults, showed a strong correlation between being exposed to harmful family environments and depressive symptoms among the elderly. Efforts to address family risk factors and strengthen family cohesiveness deserve a higher priority, given the importance of these factors, compared with other efforts such as promoting economic development.

Background: The aim of the present study was to investigate the differences in the prevalence of and risk factors for elderly depression between urban and rural areas in Japan and to further understanding of the features of elderly depression.

Methods: A multistage, random sampling procedure and mailing method were used in urban and rural areas in Kumamoto Prefecture. A total of 2,152 participants aged 65 years and older were evaluated for depression using the Geriatric Depression Scale (GDS). Factors associated with depression were also examined. In order to assess the relationship between risk factors and subjective happiness, the Philadelphia Geriatric Center Morale Scale (PGC-MS) was used.

Results: Depressive symptoms were associated with living alone, being unemployed, chronic illness, sleep disturbance, suicidal ideation, financial strain, and poor social support; the risk factors for elderly depression were almost the same in the two areas. Although three factors (financial strain, work status, and PGC-MS) were significantly associated with depression in both areas on logistic regression analysis, sleep disturbance was significant only for the urban area, and poor social support was significant only for the rural area.

Conclusions: Although factors related to depression did not differ markedly between urban and rural elderly people, some risk factors differed between the two areas. Effective intervention programs for elderly depression should pay more attention to regional differences.

Background: The aim of this study was to evaluate the effectiveness of a stepped-care program to prevent the onset of depression and anxiety disorders in elderly people living in residential homes.

Methods: A pragmatic randomized controlled trial was conducted to compare the intervention with usual care in 14 residential homes in the Netherlands. A total of 185 residents with a minimum score of 8 on the Centre for Epidemiologic Studies Depression Scale, who did not meet the diagnostic criteria for a depressive or anxiety disorder, and were not suffering from severe cognitive impairment, were recruited between April 2007 and December 2008. They were randomized to a stepped-care program (N = 93) or to usual care (N = 92). The stepped-care participants sequentially underwent watchful waiting, a self-help intervention, life review, and a consultation with the general practitioner. The primary outcome measure was the incidence of a major depressive disorder (MDD) or anxiety disorder during a period of one year according to the Mini International Neuropsychiatric Interview.

Results: The intervention was not effective in reducing the incidence of the combined outcome of depression and anxiety (incidence rate ratio (IRR) = 0.50; 95% confidence interval (CI) = 0.23–1.12). However, the intervention was superior to usual care in reducing the risk of MDD incidence (IRR = 0.26; 95% CI = 0.12–0.80) contrary to anxiety incidence (IRR = 1.32; 95% CI = 0.48–3.62).

Conclusions: These results suggest that the stepped-care program is effective in reducing the incidence of depression, but is not effective in preventing the onset of anxiety disorders in elderly people living in residential homes.

Background: Antidepressants are commonly prescribed medications in the elderly, but their relationship with incident mild cognitive impairment (MCI) and probable dementia is unknown.

Methods: The study cohort included 6,998 cognitively healthy, postmenopausal women, aged 65–79 years, who were enrolled in a hormone therapy clinical trial and had baseline depressive symptoms and antidepressant use history assessments at enrollment, and at least one postbaseline cognitive measurement. Participants were followed annually and the follow-up averaged 7.5 years for MCI and probable dementia outcomes. A central adjudication committee classified the presence of MCI and probable dementia based on extensive neuropsychiatric examination.

Results: Three hundred and eighty-three (5%) women were on antidepressants at baseline. Antidepressant use was associated with a 70% increased risk of MCI, after controlling for potential covariates including the degree of depressive symptom severity. Selective serotonin reuptake inhibitors (SSRIs) and tricyclic antidepressants (TCAs) were both associated with MCI (SSRIs: hazard ratios (HR), 1.78 [95% CI, 1.01–3.13]; TCAs: HR, 1.78 [95% CI, 0.99–3.21]). Depressed users (HR, 2.44 [95% CI, 1.24–4.80]), non-depressed users (HR, 1.79 [95% CI, 1.13–2.85]), and depressed non-users (HR, 1.62 [95% CI, 1.13–2.32]) had increased risk of incident MCI. Similarly, all three groups had increased risk of either MCI or dementia, relative to the control cohort.

Conclusions: Antidepressant use and different levels of depression severity were associated with subsequent cognitive impairment in a large cohort of postmenopausal women. Future research should examine the role of antidepressants in the depression–dementia relationship and determine if antidepressants can prevent incident MCI and dementia in individuals with late-life depression subtypes with different levels of severity.

Background: Anxiety and depression are common in older people but are often missed; to improve detection we must focus on those elderly people at risk. Frailty is a geriatric syndrome inferring increased risk of poor outcomes. Our objective was to explore the relationship between frailty and clinically significant anxiety and depression in later life.

Methods: This study had a cross-sectional design and involved the assessment of 567 community-dwelling people aged ≥60 years recruited from the Technology Research for Independent Living (TRIL) Clinic, Dublin. Frailty was measured using the Fried biological syndrome model; depressive symptoms were assessed using the Center for Epidemiological Studies Depression Scale; and anxiety symptoms measured using the Hospital Anxiety and Depression Scale.

Results: Higher depression and anxiety scores were identified in both pre-frail and frail groups compared to robust elders (three-way factorial ANOVA, p ≤0.0001). In a logistic regression model the odds ratio for frailty showed a significantly higher likelihood of clinically meaningful depressive and anxiety symptoms even controlling for age, gender and a history of depression or anxiety requiring pharmacotherapy (OR = 4.3; 95% CI 1.5, 11.9; p = 0.005; OR = 4.36; 95% CI 1.4, 13.8; p = 0.013 respectively).

Conclusions: Our findings suggest that even at the earliest stage of pre-frailty, there is an association with increased symptoms of emotional distress; once frailty develops there is a higher likelihood of clinically significant depression and anxiety. Frailty may be relevant in identifying older people at risk of deteriorating mental health.

Background: Alcohol use disorders are associated with other mental health disorders in young adults, but there are few data on alcohol use and mental health outcomes in older adults, particularly the oldest old. This study examines the relationship between alcohol consumption and depressive symptoms.

Methods: Data were collected from the Dynamic Analyses to Optimise Ageing (DYNOPTA) project, which has pooled nine Australian longitudinal studies. Alcohol consumption was classified using standard drinks (10 g alcohol)/day as: abstinent, low risk (<0–≤2 standard drinks), long-term risk (>2–≤4) and short-term risk (>4). Probable depression was classified from harmonized scores on various standard instruments (e.g. Centre for Epidemiological Studies Depression scale).

Results: Overall, 39,104 (86%) participants contributed data. Alcohol classification at baseline showed 7,526 abstinent, 28,112 low risk, 2,271 long-term risk, and 1,195 short-term risk participants. Age ranged from 45 to 103 year (median 60). Using generalized estimating equations (GEE), there were significant gender by alcohol and gender by age interactions, so the analysis was split by gender. Among males, the abstinent and short-term risk groups had increased likelihood of depression: in females the abstinent, long- and short-term risk groups had increased odds of depression. Increased odds of depression was also associated with former and current smoking, younger age-group, not being partnered, leaving school before age 15 and increasing levels of health-impaired walking, dressing, or bathing.

Conclusion: The impact of alcohol use differs by gender, nevertheless those using higher levels of alcohol or who smoke should be screened for depression and may benefit from interventions.

Background: Depressive symptoms are prevalent among persons with dementia (PWD). Our aim was to assess the psychometric properties of the Spanish version of the Geriatric Depression Scale (GDS-15 and GDS-5) in PWD.

Methods: In this cross-sectional study, five healthcare centers providing care for PWD from two cities in Spain participated. Ninety-six community-dwelling PWD aged 55 years and older, living with a known caregiver, completed a battery of scales including the GDS-15 and GDS-5, the Cornell Scale Depression in Dementia (CSDD), a list of self-reported chronic health conditions (yes/no), severity of dementia (Mini-Mental State Examination), functional status (Barthel Index), generic quality of life (WHOQOL-BREF), and sociodemographic information.

Results: Cronbach's α coefficients were 0.81 and 0.72 for GDS-15 and GDS-5, respectively, providing evidence for acceptable internal consistency. Significant associations between the GDS-15/GDS-5, the Barthel Index, CSDD, and the WHOQOL-BREF were found. No significant differences were found on GDS-15/GDS-5 scores among dementia diagnostic groups (Alzheimer's disease, vascular dementia, mixed dementia, other dementia) or between mild (MMSE 21–26) and moderate (MMSE 10–20) dementia. Participants self-reporting depression on the comorbid condition list (yes) scored significantly higher on the GDS-15 and GDS-5 compared to those who reported not having depression. Exploratory factor analyses suggested a two-factor structure on GDS-15 which accounted for 41.6% of the variability, while the one-factor structure on the GDS-5 accounted for 48.1% of the variability.

Conclusions: In general, this study provides evidence that GDS-15 and GDS-5 are suitable measures for screening depressive symptoms in community-dwelling PWD.

Background: There are few studies on validation of depression scales in the elderly in Latin America. This study aimed to assess the validity of Montgomery-Åsberg. Depression Rating Scale (MADRS) and Cornell Scale for Depression in Dementia (CSDD) in Brazilian elderly outpatients.

Methods: A convenience sample of 95 outpatients was diagnosed for dementia and depression according to DSM-IV-TR, ICD-10, and PDC-dAD criteria. Receiver Operating Curves (ROC) were used to calculate the area under the curve (AUC) and to assess MADRS and CSDD cut-offs for each diagnostic criterion.

Results: Dementia was diagnosed in 71 of 95 patients. Depression was diagnosed in 35, 30, and 51 patients by ICD-10, DSM-IV, and PDC-dAD, respectively. MADRS cut-off score of 10 correctly diagnosed 67.4% and 66.3% patients as depressed according to DSM-IV and ICD-10. A cut-off of 9 correctly identified 74.7% by PDC-dAD criteria; a CSDD cut-off score of 13 best recognized depression according to DSM-IV and ICD-10. A score of 11 diagnosed depression according to PDC-dAD, while MADRS = 9 recognized depression in dementia. CSDD was more efficient in showing depression in mild than in moderate/severe dementia according to DSM-IV/ICD-10. PDC-dAD behaved nicely for any severity stage.

Conclusion: MADRS and CSDD cut-offs of 10 and 13 were the optimal ones to diagnose depression in elderly, respectively. CSDD cut-offs are higher than those found in other countries. Other Latin American studies are needed to compare results with our study.

Background: Depression is a common behavioral and psychological symptom of Alzheimer's disease (AD). The aims of the present study were to determine the rate of depression in Taiwanese patients with AD using the National Institutes of Mental Health Provisional Criteria for Depression in AD (NIMH-dAD criteria) and to investigate the association of depression with other behavioral and psychological symptoms.

Methods: A consecutive series of 302 AD patients registered in a dementia clinic were investigated in this study. All patients met the criteria of the National Institute of Neurological Disorders and Stroke–Alzheimer's Disease and Related Disorders Association for probable AD. The rates of depression were determined according to the criteria of the fourth edition of the Diagnostic and Statistical Manual of Mental Disorders for major depression (DSM-IV), the International Classification of Diseases-9-Clinical Modification (ICD-9-CM) for neurotic depression, the depression subscale of the Neuropsychiatric Inventory (NPI), and the NIMH-dAD criteria. Depression severity was assessed using the 17-item Hamilton Depression Rating Scale. The rates of depression determined by the NIMH-dAD criteria were compared with the rates derived from each of the other instruments. Other behavioral and psychological symptoms were assessed using NPI. A behavioral neurologist or a geriatric psychiatrist interviewed all the patients.

Results: Using the NIMH-dAD criteria, it was found that 90 (29.8%) of the AD patients had depression, and all depressive symptoms in NIMH-dAD were significantly higher among depressed patients. Among other depression instruments, the frequency of depression was lowest using the DSM-IV major depression criteria (9.3%) and highest with the NPI depression subscale (54%). Behavioral and psychological symptoms determined with NPI were significantly higher among depressed patients in all domains except euphoria.

Conclusions: This is the first study of depression in Taiwanese patients with AD using the NIMH-dAD criteria. Our findings suggest that comorbid depression is high in Taiwanese patients with AD. It is clinically important to note the high frequency of most behavioral and psychological symptoms among depressed AD patients.

Background: There is little empirical research regarding the relationships between identity and well-being in people with dementia. The aim of the study was to explore the relationship of identity with mood and quality of life (QoL) in the people in the early stages of dementia.

Method: This was a cross-sectional questionnaire-based study. Fifty people in the early stages of dementia completed measures pertaining to different aspects of identity, mood, and QoL. Multiple regression analyses were carried out to determine whether it was possible to predict any of the variance in mood and QoL from aspects of identity.

Results: It was possible to predict 12.8% of the variance in anxiety, 23.4% of the variance in depression, and 25.1% of the variance in QoL from different aspects of identity. Predictors varied for each dependent variable.

Conclusions: Aspects of identity predict a modest proportion of the variance in anxiety, depression, and QoL. This suggests that supporting identity in people with dementia who are experiencing difficulties in this regard might have a positive impact on mood and QoL. However, the majority of the variance in mood and QoL must be accounted for by other variables.

Background: Dementia caregiving has been linked to negative consequences for mental health in caregivers. Although depression seems to be an enduring psychological consequence associated with caregiving, little is known about the longitudinal effects that modulating variables related to coping strategies have on caregiver's changes in depression over time. This study is aimed at investigating whether, in a one-year longitudinal study with 130 dementia caregivers, caregivers’ depression scores co-vary with modulating variables such as self-efficacy for controlling upsetting thoughts, frequency of leisure activities, and cognitive reappraisal, after controlling for gender and caregivers’ stressors (frequency of disruptive behaviors).

Methods: Linear mixed models analysis was used to analyze the associations between time-varying values for caregivers’ stressors and modulating variables in predicting caregivers’ depression.

Results: It was found that increases in caregivers’ self-efficacy, frequency of leisure activities, and cognitive reappraisal significantly predicted decreases in caregivers’ depression over time, even after controlling for gender and frequency of disruptive behaviors. In addition, increases in stressors were significantly related to increases in depression over time.

Conclusions: The inclusion of modulating variables significantly contributed to the explanation of the variance in caregivers’ depression, adding explanatory power to the variables usually included in the stress and coping model (gender and stressors).

Background: Caregiving for people with Alzheimer's disease (AD) is highly stressful and has significant negative consequences, such as anxiety and depression. Previous research offers conflicting findings as to whether coping strategies are associated with greater psychological distress or not. We conducted this study with a view to obtaining new data regarding the association of coping strategies and psychological distress in AD caregivers.

Methods: Eighty people with AD and their primary caregivers living in the community were recruited from local health services. Purposive recruitment was carried out to ensure that the sample was representative of people living with dementia in terms of dementia severity, gender, and care setting. We used the State-Trait Anxiety Inventory to measure anxiety, the Beck Depression Inventory to measure depression, and the Coping Strategies Inventory to measure coping strategies.

Results: Most caregivers reported higher anxiety and depression levels. Use of disengagement coping strategies (Wald = 3.35, p = 0.01) and higher caregiver burden (Wald = 4.83, p = 0.02) predicted anxiety on logistic regression. In turn, use of disengagement coping strategies (Wald = 12.48, p = 0.001) and higher caregiver burden (Wald = 6.91, p = 0.009) predicted depression on logistic regression.

Conclusion: These results may be useful for designing treatment interventions that aim to modify the use of coping strategies and thus reduces caregiver anxiety and depression.

Background: This paper determines care recipient and caregiver characteristics and caregiving dimensions – associated with depression among caregivers of older adults, using path analysis and assesses whether the identified path model differs between spousal and adult child caregivers.

Methods: Data from 1,190 dyads comprising care recipients (community-dwelling adults aged ≥75 years with at least one activity of daily living (ADL) limitation) and caregivers (family member/friend most involved in providing care/ensuring provision of care to care recipient), who were interviewed through the Singapore Survey on Informal Caregiving (2010–2011), were used. Using path analysis, we assessed the direct and indirect associations between primary stressors (care recipient's ADL and instrumental ADL status, and memory and behavior problems), caregiver health status, receipt of assistance from a foreign domestic worker/maid, amount of caregiving, negative reaction to caregiving, caregiver's self-esteem, perceived emotional support, and caregiver depressive symptoms.

Results: Our analysis showed that primary stressors, receipt of assistance from a foreign domestic worker/maid, perceived emotional support, and caregiver health status were directly or indirectly associated with caregiver depressive symptoms, and this association was mediated by negative reaction to caregiving. Caregiver self-esteem mediated the relationship between perceived emotional support and negative reaction to caregiving only among adult child caregivers.

Conclusions: The results provide insights into factors associated with depressive symptoms among spousal and adult child caregivers, and help identify targeted interventions for improving caregiver mood.

Background: Frailty can be defined as the presence of multiple, interacting medical and functional problems. Frailty is associated with psychiatric conditions but its relation to psychological well-being is unclear. A “frailty identity crisis” has been proposed as a maladaptive response to the sense of self as health deficits accumulate. We evaluated this so-called identity crisis by investigating associations between well-being, frailty, and mortality in community-dwelling older Canadians.

Methods: In this secondary analysis of the Canadian Study of Health and Aging (N = 5,703; age 70+), frailty was defined by an index of 33 health deficits. Psychological well-being was measured using Ryff's 18-item scale, with six domains (autonomy, personal growth, environmental mastery, positive relations, purpose in life, and self-acceptance). Cognition was measured using the Modified Mini-Mental State Examination. Associations between well-being, frailty, and mortality were measured using linear regression, adjusting for age, sex, education, cognition, and mental health.

Results: For each additional frailty-defining deficit, the psychological well-being score worsened by 0.3 points (0.29, 95% CI: 0.22–0.36, p < 0.001), independent of age, sex, education, cognition, and mental health. Among the six domains of well-being, only “purpose in life” and “autonomy” were not associated with frailty (all others, p < 0.001). Worse psychological well-being was associated with five-year mortality independent of age, sex, education, frailty, and mental health; this association was not statistically significant when adjusting for baseline cognition.

Conclusions: Frailty was associated with low levels of well-being. Psychological well-being impaired by a frailty identity crisis may play an important role in defining subjective health in older adults.

Background: Wartime rape is an atrocity with long-lasting impacts not only on victims but whole societies. In this brief report, we present data on experience and witness of sexual violence during World War II (WWII) and subsequent time of occupation and on indicators of mental health in a sample of elderly Austrians.

Methods: Interviews of 298 elderly Austrians from a larger epidemiological study on WWII traumatization were analyzed for the impact of experience and witness of sexual violence during the wartime committed by occupational forces. Interviews comprised a biographical/historical section and psychological measures (BSI, TLEQ, PCL–C). Participants were recruited in all nine provinces of Austria with respect to former zones of occupation (Western Allied/Soviet).

Results: Twelve persons reported direct experience of sexual violence, 33 persons witnessed such atrocities. One third of the victims and 18.2% of the witnesses reported post-traumatic stress disorder (PTSD full/subthreshold). Sexual violence occurred more often in the former Soviet zone. Victims and witnesses displayed higher odds of post-traumatic symptoms and symptoms of depression and phobic fear than non-victims. Furthermore, witnesses displayed higher levels of aggression compared to victims and non-witnesses.

Conclusions: Our results corroborate previous findings that wartime rape has long-lasting effects over decades on current mental health and post-traumatic distress in victims and witnesses. We recommend integration of psychotraumatological knowledge on consequences of sexual violence on mental health into geriatric care and the education of dedicated personnel.

We would like to congratulate Aprahamian et al. (2011) for their initiative to investigate the psychometric properties of the Cambridge Cognition Examination (CAMCOG) in assessing the cognitive status of the Brazilian elderly. This instrument is very frequently used in Brazil, but its measure characteristics have not yet been fully determined. Of course, cross-cultural adaptation and validation are rarely a simple procedure, often demanding a research program to completely adapt the tool to the specific language, culture, and selected population. In our opinion, the paper “Can the CAMCOG be a good cognitive test for patients with Alzheimer's disease with low levels of education?” (Aprahamian et al., 2011) is welcome as another trial by Brazilian scientists in this ongoing process. Notwithstanding, we believe that some comments about the methodological aspects of the paper are in order.

We thank you for the opportunity to respond to the letter written by Dr. Lourenço and Dr. Paradela, our colleagues from Rio de Janeiro. We understand scientific progress relies on lively debate and exchange of experiences; therefore, we also thank our colleagues for the opportunity to reflect upon our previous findings.
