Background: Elderly Sri Lankans (11.2% of the nation's population) have witnessed many years of ethnic conflict, a destructive tsunami and increasing emigration of young adults. However, very little is known about the prevalence and correlates of depression among them. The present study utilizes data from a national aging survey to document the prevalence and correlates of clinically significant depressive symptoms among community-dwelling elderly Sri Lankans (aged ≥60 years).

Methods: The 15-item Geriatric Depression Scale (GDS-15) was administered to 1181 elderly Sri Lankans; the presence of clinically significant depressive symptoms was defined as a GDS-15 score of ≥6. Sociodemographic and health correlates of depressive symptoms were assessed using logistic regression analysis. Interactions between gender and other correlates were also assessed.

Results: The prevalence of depressive symptoms was observed to be 27.8% overall: 24.0% for men, and 30.8% for women. Certain subgroups of the elderly, i.e. those with disabilities, functional limitations, perceived income inadequacy, minorities, and elderly living alone, were significantly more likely to report depressive symptoms. There was a significant interaction between gender and ethnicity.

Conclusion: The prevalence of depressive symptoms among Sri Lankan elderly people is higher than that reported for most Asian countries. Clinicians and caregivers need to be aware of the potential presence of depressive symptoms among the elderly, especially among those with lower educational levels, functional limitations, hearing difficulty, physical disability, perceived income inadequacy, and among those who live alone, and ethnic minority males.

Background: This study aimed to characterize healthcare and human services utilization among mentally distressed and non-distressed clients receiving in-home care management assessment by aging services provider network (ASPN) agencies in the U.S.A.

Methods: A two-hour research interview was administered to 378 English-speaking ASPN clients aged 60+ years in Monroe County, NY. A modified Cornell Services Index measured service utilization for the 90 days prior to the ASPN assessment. Clients with clinically significant anxiety or depressive symptoms were considered distressed.

Results: ASPN clients utilized a mean of 2.93 healthcare and 1.54 human services. The 42% of subjects who were distressed accessed more healthcare services (e.g. mental health, intensive medical services) and had more outpatient visits and days hospitalized than the non-distressed group. Contrary to expectations, distressed clients did not receive more human services. Among those who were distressed, over half had discussed their mental health with a medical professional in the past year, and half were currently taking a medication for their emotional state. A far smaller proportion had seen a mental health professional.

Conclusions: In the U.S.A., aging services providers serve a population with high medical illness burden and medical service utilization. Many clients also suffer from anxiety and depression, which they often have discussed with a medical professional and for which they are receiving medications. Few, however, have seen a mental health specialist preceding intake by the ASPN agency. Optimal care for this vulnerable, service intensive group would integrate primary medical and mental healthcare with delivery of community-based social services for older adults.

Background: This paper was written as a result of the International Psychogeriatric Association Task Force on Mental Health Services in Long-Term Care. The appraisal presented here aims to (1) identify the best available evidence that underpins best practice for geriatric mental health education and training of staff working in long-term care, and (2) summarize the appraisal of the literature to provide recommendations for practice.

Methods: An initial search of databases found 138 papers related to the search strategy. Selected papers were summarized and compared against set inclusion criteria. This resulted in 17 papers suitable for review.

Results: The majority of papers focused on behavior skills training. A number of key factors were identified that determine the success of geriatric mental health education and training and recommendations are outlined.

Conclusions: Methodological weaknesses are common and highlight the need for further replication studies using strong research designs.

Background: Few studies have specifically examined mental health service delivery to persons aged over 84 years, often described as the “old” old. Our aim was to compare mental health service provision in Australia to persons aged 85 years and over with the “young” old and other age groups. We hypothesized that the “old” old would differ from the “young” old (65–84 years) by diagnostic category, rates of specialist psychiatric hospital admission, and use of Medicare funded psychiatric consultations in the community.

Methods: Mental health service delivery data for 2001–02 to 2005–06 was obtained from Medicare Australia on consultant psychiatrist office-based, home visit and private hospital services subsidized by the national healthcare program and the National Hospital Morbidity database for separations (admitted episodes of patient care) from all public and most private hospitals in Australia on measures of age, gender, psychiatric diagnosis, location and type of psychiatric care.

Results: Use of specialist psychiatric services in the community per annum per 1000 persons declined with age in men and women from 137.28 and 191.87 respectively in those aged 20–64 years to 11.84 and 14.76 respectively in those over 84 years. However, men and women over 84 years received psychiatric home visits at 377% and 472% respectively of the rates of persons under 65. The annual hospital separation rate per 1000 persons for specialist psychiatric care was lowest in those aged over 84 (3.98) but for inpatient non-specialized psychiatric care was highest in those over 84 (21.20). Depression was the most common diagnosis in specialized psychiatric hospitalization in those aged over 84 while organic disorders predominated in non-specialized care in each age group over 64 years with the highest rates in those aged over 84.

Conclusion: Mental health service delivery to persons aged over 84 is distinctly different to that provided to other aged groups being largely provided in non-specialist hospital and residential settings.

Background: Prospective studies on the clinical progression of Alzheimer's disease (AD) and its relationship to caregiver burden are needed to improve illness management and use of resources.

Methods: This national, multicenter, observational study evaluated 1235 moderate to severe AD patients under routine care in Spain. Baseline cross-sectional sociodemographic and clinical data, and changes from baseline to month 12 of various neuropsychological tests and clinical ratings, including Blessed Dementia Scale, Mini-mental State Examination (MMSE), Hughes Clinical Dementia Rating sum-of-boxes (CDR-SB), Clinical Global Impression of Change (CGIC) and Zarit Caregiver Burden scales, were recorded and comprehensively analyzed.

Results: Baseline data were in accordance with characteristics consistently reported to influence AD risk regarding anthropometrics, sociocultural features and comorbidities. Significant progressive functional impairments (i.e. in routine activities and essential daily tasks) and cognitive (i.e. MMSE and CDR-SB) impairments were found at month 12. However, patients' behavior and caregivers' burden improved slightly, but significantly, corroborating the major influence of behavioral symptoms on caregivers' distress. Caregivers showed significantly lower burden with patients with higher levels of education and, to a lesser extent, when patients received AD-specific medication. Physicians accurately detected AD clinical evolution as their CGIC ratings significantly correlated with all tests.

Conclusions: These findings reinforce previous AD knowledge and add data on the clinical course of advanced stages of AD. Caregiver burden depended more on patients' behavioral alterations than on their functional or cognitive declines; and it was diminished by their patients having higher levels of education and being treated with AD-specific medications. Research into unexplored factors that might reduce caregiver burden, ultimately benefiting both patients and caregivers, is encouraged.

Introduction: The International Psychogeriatric Association Task Force on Mental Health Services in Long-Term Care Facilities seeks to improve care of persons in residential aged care facilities (RACFs). As part of that effort the current authors have contributed an overview and discussion of the uses of brief screening instruments in RACFs.

Methods: While no current guidelines on the use of screening instruments in nursing homes were found, relevant extant guidelines were consulted. The literature on measurement development, testing standards, psychometric considerations and the nursing home environment were consulted.

Results: Cognitive, psychiatric, behavioral, functional and omnibus screening instruments are described at a category level, along with specifics about their use in a RACF environment. Issues surrounding the selection, administration, interpretation and uses of screening instruments in RACFs are discussed. Issues of international interest (such as translation of measures) or clinical concern (e.g. impact of severe cognitive decline on assessment) are addressed. Practical points surrounding who can administer, score and interpret such screens, as well as their psychometric and clinical strengths more broadly, are articulated.

Conclusions: Guidelines for use of screening instruments in the RACF environment are offered, together with broad recommendations concerning the appropriate use of brief screening instruments in RACFs. Directions for future research and policy directions are outlined, with particular reference to the international context.

Background: The prevalence of depression among older people receiving care is high, yet the rate of treatment of this disorder is low. One way to improve the pathway to care is to train care staff to recognize the symptoms of depression and raise their confidence in responding to them. In this study we evaluated the efficacy of the beyondblue Depression Training Program to achieve this aim.

Methods: Staff (N = 148) from low level care facilities and community care facilities in metropolitan Melbourne completed the beyondblue Depression Training Program, while staff in other facilities (N = 96) acted as controls. Pre-program, post-program and follow-up questionnaire data were collected and referrals for depression by staff were recorded.

Results: Training improved carers’ knowledge about depression, their self-efficacy in responding to signs of depression and their attitudes towards working with depressed aged care recipients. In addition, training increased the number of referrals for depression made by carers.

Conclusion: Training aged care staff in depression can improve the pathways to care for depressed care recipients, and has the potential to improve the quality of life of older people.

Background: The Mini-mental State Examination (MMSE) is the most widely used cognitive test, both in clinical settings and in epidemiological studies. However, correcting its score for education may create ceiling effects when used for poorly educated people and floor effects for those with higher education.

Methods: MMSE and a recent cognitive test, the seven minute screen (7MS), were serially administered to a community sample of Mexican elderly. 7MS test scores were equated to MMSE scores. MMSE-equated 7MS differences indicated ceiling or floor effects. An ordinal logistic regression model was fitted to identify predictors of such effects.

Results: Poorly educated persons were more prevalent on the side of MMSE ceiling effects. Concentration (serial-sevens), orientation and memory were the three MMSE subscales showing the strongest relationship to MMSE ceiling effects in the multivariate model.

Conclusion: Even when MMSE scores are corrected for educational level they still have ceiling and floor effects. These effects should be considered when interpreting data from longitudinal studies of cognitive decline. When an education-adjusted MMSE test is used to screen for cognitive impairment, additional testing may be required to rule out the possibility of mild cognitive impairment.

Background: Subjective Memory Complaints (SMCs) are common among middle-aged and older adults and are often a source of distress and worry. However, rates of help-seeking are low. Investigating perceptions of SMCs may help us better to understand psychological reactions to SMCs and help-seeking behavior. The present study had two aims: (i) to investigate whether the dimensions drawn from the Common Sense Model of Illness Perception (Leventhal et al., 1984) provide a valid model of perceptions held by patients with SMCs; and (ii) to develop a questionnaire to measure these perceptions.

Methods: Qualitative interviews to explore perceptions of SMCs were conducted with 32 participants recruited from a memory clinic and community groups. Information from these interviews was utilized to adapt the Illness Perception Questionnaire – Revised (IPQ-R) for use with patients with SMCs. Ninety-eight such patients then completed the adapted questionnaire along with measures of cognition, depression and subjective memory function.

Results: The dimensions of illness perception measured by the IPQ-R were present in participant accounts of SMCs with the exception of Timeline Cyclical. The adapted measure (IPQ-M) showed good validity and reliability.

Conclusions: The development of the IPQ-M provides opportunities for further investigation of illness perceptions and their relationship to psychological distress and help-seeking behavior in SMCs. Furthermore, investigation of these relationships may provide a basis from which to develop interventions to improve well-being and help-seeking in older adults with SMCs.

Background: Depression is one of the leading contributors to the burden of non-fatal diseases in Australia. Although there is an overall increasing trend in antidepressant use, the relationship between use of antidepressants and depressive symptomatology is not clear, particularly in the older population.

Methods: Data for this study were obtained from the Australian Longitudinal Study of Ageing (ALSA), a cohort of 2087 people aged over 65 years at baseline. Four waves of home interviews were conducted between 1992 and 2004 to collect information on sociodemographic and health status. Depressive symptoms were measured by the Center for Epidemiologic Studies – Depression Scale. Use of antidepressants was based on self-report, with the interviewer able to check packaging details if available. Longitudinal analysis was performed using logistic generalized estimating equations to detect if there was any trend in the use of antidepressants, adjusting for potential confounding factors.

Results: The prevalence of depressive symptoms was 15.2% in 1992 and 15.8% in 2004 (p > 0.05). The prevalence of antidepressant users increased from 6.5% to 10.9% (p < 0.01) over this period. Among people with depressive symptoms, less than 20% were taking antidepressants at any wave. Among people without depressive symptoms, the prevalence of antidepressant use was 5.2% in 1992 and 12.0% in 2004 (p < 0.01). Being female (OR = 1.67, 95%CI: 1.25–2.24), having poor self-perceived health status (OR = 1.17, 95%CI: 1.04–1.32), having physical impairment (OR = 1.48, 95%CI: 1.14–1.91) and having depressive symptoms (OR = 1.62, 95%CI: 1.24–2.13) significantly increased the use of antidepressants, while living in community (OR = 0.51, 95%CI: 0.37–0.71) reduced the risk of antidepressant use.

Conclusions: Use of antidepressants increased, while depressive symptoms remained stable, in the ALSA over a 12-year period. Use of antidepressants was low for people with depressive symptoms.

Background: This study aimed to examine the levels and rates of depression in Chinese residents living in ethno-specific nursing homes (NHs), and Chinese residents living in mainstream NHs in Sydney. Australia has a growing aging migrant population and rates of depression in NHs are high, but the prevalence of depression in culturally and linguistically diverse residents has received little attention in the research literature.

Methods: Older persons from a Chinese background residing in either Chinese-specific or mainstream NHs located in Sydney were invited to participate in a cross-sectional survey. Assessments included the Mini-mental State Examination, the Cornell Scale for Depression in Dementia (CSDD), and interviews with family carers and staff.

Results: Fifty-eight Chinese residents were recruited from three Chinese-specific NHs (n = 31) and 13 mainstream NHs (n = 27). There were no significant differences in resident depression levels or rates between the facility types. Mean CSDD scores were 9.4 (SD = 6.0) and 11.2 (SD = 6.1) in Chinese-specific and mainstream NHs, respectively. Chinese-specific NH residents had lower prescription levels of antipsychotics and more of them received effective antidepressant therapy in comparison to those in mainstream NHs.

Conclusions: These findings suggest that in comparison to mainstream care Chinese ethno-specific care does not impact on levels or rates of depression but is associated with less antipsychotic use and higher numbers of residents treated effectively with antidepressant therapy. Longitudinal research with larger samples and a range of outcome measures including quality-of-life and social engagement is required to explore further the effects of ethno-specific care.

Background: Dementia is associated with poor quality of life, but generic measures do not fully capture main aspects of these conditions. Our aim was to validate a Spanish version of the “dementia-specific health-related quality of life” DEMQOL system.

Methods: We validated the Spanish DEMQOL and DEMQOL-Proxy in 119 people with dementia from six centers and their caregivers. Patient-reported information, including generic (WHOQOL-BREF) and dementia-specific (DEMQOL) health-related quality of life, depressive symptoms (GDS-15), functional ability (Barthel Index), subjective perception of health and demographic information, was obtained by interview. Proxy-reported information from a family caregiver about the patient's quality of life (DEMQOL-Proxy) was also obtained by interview.

Results: The Spanish DEMQOL showed good psychometric properties. Acceptability (14.3% missing data), internal consistency (Cronbach's α = 0.85) and test-retest reliability (ICC = 0.71) were good. A priori hypotheses about the relationship between DEMQOL and the WHOQOL-BREF (psychological and physical domains), GDS-15 and Barthel Index were confirmed, indicating good construct validity. Associations between DEMQOL-Proxy and other measures were weaker. A three-factor solution accounted for 44.4% of the total variance of DEMQOL, and a four-factor solution accounted for 53.3% of the total variance of DEMQOL- Proxy.

Conclusion: The Spanish versions of DEMQOL and DEMQOL-Proxy are reliable and valid in patients with mild/moderate dementia who are living at home.

Background: People with Alzheimer's disease (AD) who present with prominent frontal features such as a dysexecutive syndrome may be difficult to differentiate clinically from subjects with frontotemporal lobar degeneration (FTLD). This study was performed to improve the differential diagnosis between AD and FTLD and to better characterize the AD subgroup with greater executive dysfunction.

Methods: Using a well-defined prospectively studied cohort of cognitively impaired subjects, which included those with AD and with FTLD, we nominated a frontal variant of AD (FvAD) group as those AD subjects with the lowest quartile of scores on the Frontal Assessment Battery (FAB), indicating greatest executive dysfunction, and compared them with the rest of the AD cases (whom we called the AD group) and those with FTLD across several baseline variables including cognitive, functional and behavioral scales. We also compared the changes from baseline for these three groups at 6 and 12 months. Additionally, we controlled for dementia severity by matching AD and FTLD cases on a functional scale, the SMAF, and repeated the same comparisons with these severity-matched groups.

Results: The 114 FvAD subjects had a mean age of 78.1 years and Mini-mental State Examination (MMSE) scores of 16.6, and the (remaining) AD group had a mean age of 78.4 years and MMSE of 22.4. There were 30 FTLD subjects with a mean age at baseline of 70.9 years and a mean baseline MMSE of 23.4. The FvAD group was significantly more severely impaired than the other two groups on all baseline assessments except the behavioral scale, the Neuropsychiatric Inventory (NPI), where there was insignificantly less impairment than in the FTLD group. In the analysis of subjects matched at baseline for functional impairment, the FvAD and FTLD groups were not significantly different on most assessment scales although on the FAB, clock-drawing and MMSE the FvAD subjects were still significantly more impaired. These two severity-matched groups were also similar in other baseline characteristics except for older age and less psychotropic use in the FvAD group. The severity-matched FvAD group was significantly different from the AD group in almost all assessment scales. All three unmatched and matched groups declined similarly over 12 months.

Conclusions: When groups were not matched for baseline severity, the use of the FAB defined a group of AD subjects with greater executive dysfunction that were distinguished from both the remainder of the AD and FTLD subjects in almost all domains except behavioral disturbance and probably were just more severely affected AD subjects. The FAB is thus more useful as a marker of dementia severity than as a scale to detect a frontal variant of AD or to distinguish AD from FTLD. Controlling for severity, however, did allow the definition of a subgroup of AD subjects that more closely resembled FTLD subjects than the remainder of the AD subjects. It is proposed that subjects with dementia presenting with greater executive impairment but without prominent behavioral symptoms are likely to have AD rather than FTLD, especially if they are quite functionally impaired. With time FTLD subjects develop increasing executive dysfunction and increasingly resemble the more severely affected AD subjects.

Background: There is uncertainty regarding the optimal use of pharmacological strategies in delirium particularly regarding preferred agents, duration of treatment and effectiveness in different populations.

Methods: Attitudes towards delirium pharmacotherapy were investigated before and after an educational workshop using the format of a televison game show.

Results: Most respondents (65/66) reported psychotropic use with variable frequency (median 60%). Antipsychotic use was inversely related to perception of supporting evidence (p = 0.02). Respondents rated sedative (38%) and antipsychotic (33%) effects as the principal mechanism of action rather than a specific neurochemical anti-delirium effect (21%). Haloperidol was the preferred first-line agent (65%). Suggested continuation treatment after symptom resolution was three days. Eleven respondents had used psychotropics prophylactically. Antipsychotic use was influenced by concerns regarding potential for extrapyramidal (52%), sedative (32%), cerebrovascular (30%) and metabolic (8%) effects. Post-workshop concerns regarding extrapyramidal effects were reduced with a more positive general attitude towards pharmacological interventions, especially in hypoactive presentations (61%) and prophylactically in high-risk patients (56%).

Conclusions: Attitudes towards key aspects of delirium pharmacotherapy vary considerably and relate to concerns regarding side effect potential more than perceived mechanism of action. Educational interventions can impact positively upon attitudes.

Background: The ε4 allele of the apolipoprotein E (APOE) gene and low levels of cerebrospinal fluid (CSF) amyloid β-proteins 42 (Aβ) have previously been associated with increased risk of cognitive decline in old age. In this study we examine the interaction of these markers with episodic memory in a sample identified as having mild cognitive impairment (MCI).

Methods: The sample (N = 149) was drawn from the Gothenburg MCI study and measured according to three free recall tests on three occasions spanning over four years. Second-order Latent Curve Models (LCM) were fitted to the data.

Results: Analyses accounting for age, gender, education, APOE, Aβ42, and interaction between APOE and Aβ42 revealed that the ε4 allele was significantly associated with level of memory performance in the presence of low Aβ42 values (≤452 ng/L). Associations between memory performance and Aβ42 were significant among the ε4 carriers but not among the non-carriers. The Aβ42 marker was, however, significantly associated with changes in memory over the study time period in the total sample.

Conclusion: The findings support the hypothesis of an interactive effect of APOE and Aβ42 for memory decline in MCI patients.

Background: The effects of depression and cognitive impairment on hip fracture rehabilitation outcomes are not well established. We aimed to evaluate the associations of depressive symptoms and cognitive impairment (individually and combined) with ambulatory, living activities and quality of life outcomes in hip fracture rehabilitation patients.

Methods: A cohort of 146 patients were assessed on depressive symptoms (Geriatric Depression Scale, GDS ≥ 5), cognitive impairment (Mini-mental State Examination, MMSE ≤ 23), and other variables at baseline, and on ambulatory status, Modified Barthel Index (MBI), and SF-12 PCS and MCS quality of life on follow ups at discharge, 6 months and 12 months post fracture.

Results: In these patients (mean age 70.8 years, SD 10.8), 7.5% had depressive symptoms alone, 28.8% had cognitive impairment alone, 50% had both, and 13.7% had neither (reference). Ambulatory status showed improvement over time in all mood and cognition groups ((β = 0.008, P = 0.0001). Patients who had cognitive impairment alone (β = −0.060, P = 0.001) and patients who had combined cognitive impairment with depressive symptoms β = −0.62, P = 0.0003), showed significantly less improvement in ambulatory status than reference patients. In the latter group, the relative differences in ambulatory scores from the reference group were disproportionately greater over time (β = −0.003, SE = 0.001, P = 0.021). Patients with combined depressive symptoms and cognitive impairment also showed a significantly lower MBI score, (β = −10.92, SE = 4.01, P = 0.007) and SF-12 MCS (β = −8.35, SE = 2.37, P = 0.0006). Mood and cognition status did not significantly predict mortality during the follow-up.

Conclusion: Depression and cognitive impairment comorbidity is common in hip fracture rehabilitation patients and significantly predicts poor functional and quality of life outcomes.

Background: Psychosocial interventions in long-term care have the potential to improve the quality of care and quality of life of persons with dementia. Our aim is to explore the evidence and consensus on psychosocial interventions for persons with dementia in long-term care.

Methods: This study comprises an appraisal of research reviews and of European, U.S. and Canadian dementia guidelines.

Results: Twenty-eight reviews related to long-term care psychosocial interventions were selected. Behavioral management techniques (such as behavior therapy), cognitive stimulation, and physical activities (such as walking) were shown positively to affect behavior or physical condition, or to reduce depression. There are many other promising interventions, but methodological weaknesses did not allow conclusions to be drawn. The consensus presented in the guidelines emphasized the importance of care tailored to the needs and capabilities of persons with dementia and consideration of the individual's life context.

Conclusions: Long-term care offers the possibility for planned care through individualized care plans, and consideration of the needs of persons with dementia and the individual life context. While using recommendations based on evidence and consensus is important to shape future long-term care, further well-designed research is needed on psychosocial interventions in long-term care to strengthen the evidence base for such care.

Background: The General Practitioner Cognitive Assessment of Cognition (GPCOG), a brief, efficient dementia-screening instrument for use by general practitioners (GPs), consists of cognitive test items and historical questions asked of an informant. The validity of instruments across different cultures and languages requires confirmation and so the aim of this study was to validate the Italian version of GPCOG (GPCOG-It).

Methods: The validity of the GPCOG-It was assessed against standard criteria for diagnosis of dementia (Diagnostic and Statistical Manual of Mental Disorders – 4th edition) as well as the Clinical Dementia Rating scale. The participants comprised 200 community-dwelling patients aged at least 55 years with (patient group) or without memory complaints (control group). Seven general practitioners were involved. Measurements used were the Cambridge Cognitive Assessment, Mini-mental State Examination with standard (24/25) and Italian cut-off (26/27), Alzheimer's Disease Assessment Scale-Cognitive scale and Geriatric Depression Scale.

Results: The GPCOG-It, total score and two-stage method, were at least equivalent in detecting dementia to the MMSE using the standard 24/25 or the Italian 26/27 cut-offs. The two-stage method of administering the GPCOG-It (cognitive testing followed by informant questions if necessary) had a sensitivity of 82%, a specificity of 92%, a misclassification rate of 17.4% and positive predictive value of 95%. Patient interviews took less than 4 minutes to administer and informant interviews less than 2 minutes, half the time needed for MMSE administration.

Conclusions: GPCOG-It maintains the same psychometric features and time efficiency as the original English version. Despite methodological limitations (i.e. use of defined samples), the GPCOG-It performed well in detecting clear cut and borderline cognitively impaired patients and can be introduced in the daily practice of Italian GPs.

Background: Social networks may protect depressed elders against suicidal behavior. However, conflict in important relationships may undermine the sense of social support, potentially negating the protective effects. Thus, we investigated the role of chronic interpersonal difficulties and perceived social support in depressed elders with and without suicidal thoughts and attempts.

Methods: 106 individuals aged 60 years and older participated in this cross-sectional, case-control study. They were placed in three groups: suicidal depressed, non-suicidal depressed and non-depressed. Following a detailed clinical characterization, we assessed perceived social support (Interpersonal Support Evaluation List), and chronic interpersonal difficulties (Inventory of Interpersonal Problems). Using general linear models, we explored the relationship between suicidal thoughts/attempts, social support, and chronic interpersonal difficulties. We also examined whether lower perceived social support explained the relationship between chronic interpersonal difficulties and suicidal thoughts/attempts.

Results: Suicidal depressed elders reported the lowest levels of perceived social support (belonging, tangible support, and self-esteem) and higher levels of chronic interpersonal difficulties (struggle against others and interpersonal hostility), compared to both non-suicidal depressed and non-depressed elders. The relationship between chronic interpersonal difficulties and suicidal behavior was partially explained by low perceived social support.

Conclusions: The experience of strong affects, interpersonal struggle, and hostility in relationships may undermine the sense of social support in depressed elders, possibly leading them to contemplate or attempt suicide. Depressed elders with a history of interpersonal difficulties need to be carefully monitored for suicidal behavior.

Background: Despite the magnitude of dementia, little research on survival duration and prognosis of dementia has been reported in developing countries. This study was conducted to investigate survival times, identify related prognostic factors and construct a prognostic index (PI) for community-based dementia patients in Beijing, China.

Methods: This study is part of the 10/66 Dementia Research Group study in China. One hundred and thirty-seven dementia patients identified by 10/66 dementia criteria among 2162 participants and 137 referent subjects matched by age and sex were followed up for five years.

Results: Ninety-one (66.4%) dementia patients and 51 (37.2%) referent subjects died during the 5-year follow-up (p < 0.01). The median survival time of dementia patients was 4.2 years (95% CI: 3.8–4.6). Severity of dementia (severe/mild, HR: 8.765, 95% CI: 4.436–17.163), substantial disability (HR: 5.503, 95% CI: 3.017–8.135), co-morbidity (HR: 4.149, 95% CI: 2.254–7.736) and age (HR: 1.079, 95% CI: 1.048–1.110) were independent predictors of survival for patients with dementia. Using the PI calculated for each dementia patient, all dementia patients were classified into three groups: low, medium and high risk groups. The median survival times of each group were 5.2 years, 4.4 years and 1.5 years (p < 0.01), respectively.

Conclusions: Survival times of community-based dementia patients were significantly shorter than those of referent subjects. Severity of dementia, substantial disability, co-morbidity and age were independent predictors of survival. The PI derived from the four predictors can stratify the mortality risk and predict life expectancy for community-dwelled dementia patients, although further validation is needed.
