Depression Among Caregivers of Patients With Dementia

Psychometric Properties of the Patient Health Questionnaire-9 for Saudi Caregivers: A Cross-Sectional Study in Saudi Arabia

To evaluate the psychometric properties of the Arabic-language Patient Health Questionnaire-9 (PHQ-9) among Saudi caregivers of patients with chronic diseases. Using a cross-sectional design, 94 Saudi caregivers (37 male and 57 female) in the medical city participated in the study. A comparative assessment was conducted on 4 models proposed in the existing PHQ-9 literature to gauge their compatibility through confirmatory factor analyses. This study evaluates convergent validity through a correlation analysis, examining the relationship between the PHQ-9 and the Depression, Anxiety, and Stress Scale-21 (DASS-21). Among the various models we examined, the single-factor structure of the PHQ-9 displayed the best fit with the data we gathered. Notably, the Cronbach alpha coefficient for the PHQ-9 registered at .81, indicating a high level of internal consistency. Factor loadings spanned a range from .39 to .76. The convergent validity of the PHQ-9 and DASS-21 was deemed satisfactory. It is established that the PHQ-9 serves as an effective tool for depression screening among Saudi caregivers in Saudi Arabia. Its strengths lie in its demonstrated validity, dependability, brevity, and convenience of administration, positioning it as a valuable resource for preventative measures and performance assessment within mental health settings.

Understanding the burden of mental and physical health disorders on families: findings from the Saudi National Mental Health Survey

OBJECTIVE

To assess prevalence and correlation of factors of family burden associated with mental and physical disorders in the general population of Saudi Arabia.

SETTING AND PARTICIPANTS

A secondary analysis of data from the Saudi National Mental Health Survey (SNMHS).

OUTCOME MEASURES

Mental and physical health disorders of first-degree relatives and objective (time, financial) and subjective (distress, embarrassment) family burden.

RESULTS

We found significant caregiver burden for family members with mental health disorders. Around one-third of the sample was providing care for a family member with a health issue. Within this group, 40% had a mental health diagnosis. 73% of the study population reported experiencing some form of burden as a result of the care they are obligated to provide for their family members. We found the highest burden on male caregivers, in providing care for family members with serious memory disorders, mental retardation, schizophrenia or psychosis, followed by, alcohol and drug disorders, anxiety, depression or manic depression.

CONCLUSION

Our findings for family burden were statistically significant, indicating potential negative impact on caregiver coping ability with the demands of caring for family members with health issues. A comprehensive review of national mental health policies is required to integrate aspects of community mental health promotion, scale-up prevention, screening interventions and social support to protect against the difficulties of mental illness and reduce the burden on caregivers, the family, society, health system and the economy.

Dementia care in gerontological social work: emerging issues and challenges in Saudi Arabia

The issues and challenges in the current state of gerontological social work policy, practice, and education related to dementia care in Saudi Arabia are discussed in this article. The following primary issues were explored: (1) the impact of the biomedical model's global dominance on gerontological social work policy and research for dementia care and health promotion; (2) the position of the older adults in Middle Eastern nations and its connection to the lack of gerontological social work policies, programs, and care services for older adults with dementia and their family caregivers; (3) the effect of the profession of social work's lack of recognition on the potential evolution of gerontological social work practice in dementia care; (4) the state of dementia patients' rights, dementia patients' safety, and dementia patients' rights to self-determination on the gerontological social work support provided for older adults with dementia; (5) the unequal distribution of dementia care resources and gerontological social work; and (6) the social work education programs' inability to supply the market with sufficient number of skilled gerontological social workers and its effect on the advancement of dementia care in gerontological social work practice. Approaches for advancing policy, practice, and education are provided to support the evolution of gerontological social work in dementia care in the region.

Relationship of Psychological Flexibility and Mindfulness to Caregiver Burden, and Depressive and Anxiety Symptoms in Caregivers of People with Dementia

Caregivers of People with dementia (PwD) commonly experience burdens and other mental health issues, e.g., depression and anxiety. At present, there are limited studies that examine the relationships between caregiver psychological factors and caregiver burden, and depressive and anxiety symptoms. Therefore, this study's objectives were to examine the relationships between psychological flexibility and mindfulness in caregivers of PwD, and to determine the predictors of these three outcomes. This was a cross-sectional study conducted in the geriatric psychiatry clinic of Kuala Lumpur Hospital, Malaysia, and the sample (n = 82) was recruited via a universal sampling method over three months. The participants completed a questionnaire that consisted of the sociodemographics of the PwD and caregivers, illness characteristics of the PwD, Acceptance and Action Questionnaire-II (AAQ-II), Mindful Attention Awareness Scale (MAAS), Zarit Burden Interview Scale (ZBI), Patient Health Questionnaire-9 (PHQ-9) and Generalized Anxiety Disorder-7 (GAD-7). The results show that despite significant relationships between psychological flexibility and mindfulness and lower levels of caregiver burden, and depressive and anxiety symptoms (p < 0.01), only psychological inflexibility (p < 0.01) remained as a significant predictor of the three outcomes. Therefore, in conclusion, intervention programs that target the awareness of the caregiver's psychological inflexibility should be implemented to alleviate these adverse outcomes in dementia caregivers.

Factors associated with social participation in Brazilian older adults with Alzheimer's disease: A correlational, cross-sectional study

The occurrence of Alzheimer's disease (AD) can exert a negative impact in social participation in affected older adults. The purpose of this study was to investigate whether social participation in older adults with AD is associated with disease stage and cognitive function as well as the quality of life and depressive symptoms in their caregivers. A correlational, cross-sectional study was conducted in 40 older adults with AD (28 women and 12 men) and 40 caregivers (30 women and 10 men). Social participation was assessed using the 'social participation' domain of the Activities of Daily Living Questionnaire. Disease stage was determined using the Clinical Dementia Rating scale and cognitive function was assessed using Addenbrooke's Cognitive Examination. Quality of life and depressive symptoms in the caregivers were evaluated using the Quality of Life Assessment Scale on Alzheimer's Disease and Beck Depression Inventory respectively. The older adults with AD had a mean percentage of 59.4% on the social participation domain and a mean score of 49.0 for cognitive function. The caregivers had mean scores of 39.1 for quality of life and 9.9 for depressive symptoms. The stepwise backward multiple linear regression model indicated that the predictors analysed together explained 48% of the variability in social participation among older adults with AD. Therefore, lower social participation among older adults with AD is associated with more advanced stages of the disease and cognitive decline in these individuals as well as a lower perception of quality of life and greater levels of depressive symptoms in their caregivers.

Development and validation of the care challenge scale in family caregivers of people with Alzheimer's disease

Background

Alzheimer's disease (AD) is a progressive and debilitating disorder that strongly affects people with AD and their families. The changes in signs of the disease and its treatment lead to many challenges in people with AD that affect the performance and the ability of caregivers, their social life, and physical, emotional, and psychological aspects of caregivers' health. Therefore, this study was designed to develop and validate the Care Challenge Scale (CCS) for family caregivers of people with AD in the care context of Iran.

Method

This is a cross-sectional study, and the primary scale was based on 14 semi-structured interviews with family caregivers of Iranian people with AD. In the next phase, the psychometric features were assessed, including the face validity (qualitative and quantitative), content validity (qualitative and quantitative), item analysis, structural validity (exploratory and confirmatory factors), and construct validity (convergent and discriminant validity). Finally, the reliability was assessed using internal consistency (Cronbach's alpha, McDonald's omega coefficient, and the average inter-item correlation), stability (intraclass correlation coefficient), and absolute reliability.

Results

Totally, 435 Iranian family caregivers filled out online questionnaires, with a mean age of 50.26(±13.24) years. Based on the results of the qualitative phase, an item pool was generated with 389 items, and after deleting overlapping and unrelated items, the CCS with 14 items was created. The results of the quantitative phase showed that the CCS consists of two factors with 10 items each, which are named effective role-play challenge and lack of social–financial support, and they explained 42.23% of the total variance. Furthermore, the results of confirmatory factor analysis showed a good fitness of the scale structure model, and it had convergent and discriminant validity. The reliability indexes showed this scale has internal consistency and stability.

Conclusion

The most care challenge among Iranian family caregivers of people with AD is effective role-play challenges and lack of social–financial support. The scale as designed has good validity, internal consistency, and stability that can be used by therapists, nurses, and researchers for the assessment of the challenges of this population.

The Effects of the Modified Transtheoretical Theory of Stress and Coping (TTSC) Program on Dementia Caregivers' Knowledge, Burden, and Quality of Life

This quasi-experimental study aimed to examine the effect of the modified transtheoretical theory of stress and coping (TTSC) program on the knowledge, burden, and quality of life of dementia caregivers. The participants comprised 60 caregivers (30 participants in each group) selected via purposive sampling, and the study was conducted between October 2018 and September 2019 in a semi-urban area of central Thailand. The experimental group received an 8-week program, while the comparison group received routine care. A self-administered questionnaire was used to collect data. To analyze the intervention’s effectiveness, repeat measure ANOVA and Mann–Whitney, Friedman, and Dunn’s tests were performed. At the end of the program and again three months after the end of the program, the knowledge and quality of life scores for the experimental group were significantly higher (p < 0.05 and p < 0.05, respectively) than for the control group. The burden score decreased in the experimental group and increased in the control group in week 8 (p < 0.05). There was no statistically significant difference between the groups, as demonstrated by ANOVA (F[1.58] = 2.394; p = 0.127). Our findings show that this program had a positive effect on the caregivers’ knowledge and quality of life. However, the program did not affect the caregivers’ burden.

Fruit and vegetable intake and mental health among family caregivers of people with dementia in Uganda

Consumption of fruits and vegetables is correlated with improved mental wellbeing. Although this growing body of research has been recognized by researchers and clinicians in high-income countries, fewer studies examining this relationship have been conducted in low- and middle-income settings. In this study, we sought to estimate the association between fruit and vegetable intake and symptoms of depression and anxiety. We conducted a cross-sectional study among 242 family caregivers of people with dementia in southwestern Uganda. Fruit and vegetable intake in the past week was measured with a food frequency questionnaire. Depression and anxiety were assessed using the depression and anxiety subscales of the 42-item Depression, Anxiety and Stress Scales. Multivariable regression models were used to estimate the associations between fruits and vegetable consumption and depression and anxiety, adjusting for caregiving burden and other potential confounders. Depression symptom severity was negatively associated with consumption of jackfruits (b =-4.68; 95% confidence interval [CI], -8.96 to -0.39), green leafy vegetables (b =-14.1; 95% CI, -18.0 to -10.1), root vegetables (b =-14.0; 95% CI, -19.5 to -8.63), and other vegetables (b =-14.8; 95% CI, -19.3 to -10.3), and frequent consumption of vegetables (b =-1.91; 95% CI, -3.77 to -0.04). Anxiety symptom severity was negatively associated with consumption of green leafy vegetables (b =-12.2; 95% CI, -16.0 to -8.46), root vegetables (b=-12.6; 95% CI, -17.5 to -7.58), and other vegetables (b =-12.7; 95% CI, -17.0 to -8.40), and frequent consumption of vegetables (b =-2.07; 95% CI, -3.84 to -0.29). Our results suggest that fruit and vegetable consumption is associated with reduced depression and anxiety symptoms.

Prevalence and Predictors of Caregiver Burden in a Memory Clinic Population

BACKGROUND

Although caregiver burden is common among carers of people with dementia, little is known about its prevalence and predictors among caregivers of patients attending memory clinics.

OBJECTIVE

To examine carer and patient-specific characteristics associated with caregiver burden across the cognitive spectrum in a memory clinic population.

METHODS

Consecutive patients referred to a university hospital geriatric memory clinic were included. Caregiver burden was scored using the Caregiver Burden Score (CBS), (modified Zarit), with scores≥15/30 suggesting burden. BPSD were measured with the dysfunctional behaviour rating instrument (DBRI). Cognition was screened using the Montreal Cognitive Assessment (MoCA) and Quick Mild Cognitive Impairment (Qmci) screen.

RESULTS

In all, 351 patients were included, median age 77 (±11) years; 65.5% were female. The prevalence of caregiver burden was 33.6% overall, increasing from 10.8% in subjective cognitive decline (SCD), to 15% in mild cognitive impairment (MCI) and 43% in dementia; CBS scores were significantly higher in dementia (p < 0.001). Caregivers with burden were significantly younger (p = 0.045) and were more likely to be adult children (p = 0.007). The CBS weakly correlated with the stage of cognitive impairment (r = 0.16) but had moderate correlation with MoCA (r = -0.54) and Qmci scores (r = -0.60). After adjustment for co-variates, DBRI scores alone independently predicted burden (odds ratio 1.23;1.11-1.35, p < 0.001).

CONCLUSION

Caregiver burden is associated with the stage of cognitive impairment, with higher prevalence proportions in those with dementia compared with MCI and SCD. Only the severity of neuropsychiatric symptoms independently predicted caregiver burden in this population and its presence should prompt assessment for burden.

Challenges of caregiving to neurological patients

A substantial number of neurological diseases lead to chronic impairment of activities of daily living (ADL) and physical or mental dependence. In Austria, homecare is provided mostly by female family members. Moreover, mainly female personnel, in the majority from southern and eastern European countries, contributes to care. Dependence and need for care vary between neurological diagnoses and accompanying diseases. Caregiver burden (CB) depends on patient- and caregiver-related and external factors, such as integrity of a family network, spatial resources, and socioeconomic factors. Depending on the neurological diagnosis, disease severity, and behavioral impairment and psychiatric symptoms, caregivers (CG) are at a significant risk of mental and somatic health problems because of limitations in personal needs, occupational and social obligations, financial burden, and restricted family life and leisure. Subjective and objective CB needs to be assessed in time and support should be provided on an individual basis. Recently, COVID-19 has caused additional multifactorial distress to dependent patients and informal and professional CG.

Using the Apriori Algorithm to Explore Caregivers' Depression by the Combination of the Patients with Dementia and Their Caregivers

Purpose

The purpose of this study was to identify the caring scenarios that result in severe depression in caregivers caring for dementia patients.

Patients and Methods

A cross-sectional study with 1111 dementia patients and their caregivers in Taiwan from October 2015 to January 2020 was conducted. Gender, age, type of dementia, clinical dementia rating, walking ability, mood symptoms, behavioral symptoms, and psychological symptoms were the variables from the dementia patients. Age, relation to the patient, employment, type of primary care, frequency of care, mood symptoms, and the score from the Center for Epidemiologic Studies Depression Scale were the variables from the caregivers. A comprehensive viewpoint of both dementia patients and their caregivers was evaluated by the Apriori algorithm to find the attributes resulting in different caregiving depressions.

Results

Forty-seven rules were found with 18 rules of mild depressive symptomatology, 17 rules of moderate depressive symptomatology, and 12 rules of severe depressive symptomatology. A total of 7 general rules were summarized to be the severe depressive symptomatology. The results showed that an unemployed or retired caregiver with the mood symptoms such as helplessness, anger, emotional liability, or anxiety who took care of AD patients or AD patients with a moderate severity would have severe depression. Increased care frequencies (≥6 days per week) and multiple mood problems from caregivers result in severe depression. The composition of adult children, patients' aggression, and caregivers' helplessness as well as the combinations of male patients aged 75-84 years with the caregiver's mood of helplessness or nervousness and hopelessness were highly associated with severe depression.

Conclusion

For those caring for AD patients, severe depression was associated with the combination of different parameters to constitute each of these seven scenarios. Unlike previous studies which often evaluated one or two variables related to caregiver's depression, this study provided a more comprehensive viewpoint that enabled the collaborative team to efficiently identify and manage different scenarios by summarizing the rules of caregivers with severe depression from a systematic viewpoint.

Development of multi-component counseling program for enhancing resilience among Thai caregivers of older persons with dementia

Purpose

The purpose of this study was to develop a multi-component counseling program and examine the short-term effects of an 8-session program.

Design/methodology/approach

This present study was a research and development of a multi-component counseling program for enhancing resilience. The concept of resilience was reviewed based on a synthesis of existing research, together with an exploration of qualitative data derived from an interview with ten caregivers of older persons with dementia. Six domains of resilience were identified: physical, relationships, emotional, moral, cognitive and spiritual; which were then used to develop the eight-week program. The program was examined by a panel of three experts for content validity, which yielded an index of 0.87. The program was then tried out with 60 caregivers recruited and assigned 30 caregivers in the intervention and control group. The Caregiver’s Resilience Scale (CRS) was used by trained nurses to evaluate the program and data were analyzed using repeated measures ANOVA.

Findings

The results indicated that the resilience scores of the participants in the intervention group were statistically significantly higher than those of the control group at one month after program participation and at the follow-up three months later (p < 0.05).

Originality/value

It could be concluded that the program yielded support for the evidence-based practice of non-pharmacological intervention. The program would be suitable as a clinical practice guideline to provide help to caregivers of older persons with dementia at the outpatient setting.

Assistive technology and telecare to maintain independent living at home for people with dementia: the ATTILA RCT

BACKGROUND

Assistive technology and telecare have been promoted to manage the risks associated with independent living for people with dementia, but there is limited evidence of their effectiveness.

OBJECTIVES

This trial aimed to establish whether or not assistive technology and telecare assessments and interventions extend the time that people with dementia can continue to live independently at home and whether or not they are cost-effective. Caregiver burden, the quality of life of caregivers and of people with dementia and whether or not assistive technology and telecare reduce safety risks were also investigated.

DESIGN

This was a pragmatic, randomised controlled trial. Blinding was not undertaken as it was not feasible to do so. All consenting participants were included in an intention-to-treat analysis.

SETTING

This trial was set in 12 councils in England with adult social services responsibilities.

PARTICIPANTS

Participants were people with dementia living in the community who had an identified need that might benefit from assistive technology and telecare.

INTERVENTIONS

Participants were randomly assigned to receive either assistive technology and telecare recommended by a health or social care professional to meet their assessed needs (a full assistive technology and telecare package) or a pendant alarm, non-monitored smoke and carbon monoxide detectors and a key safe (a basic assistive technology and telecare package).

MAIN OUTCOME MEASURES

The primary outcomes were time to admission to care and cost-effectiveness. Secondary outcomes assessed caregivers using the 10-item Center for Epidemiological Studies Depression Scale, the State-Trait Anxiety Inventory 6-item scale and the Zarit Burden Interview.

RESULTS

Of 495 participants, 248 were randomised to receive full assistive technology and telecare and 247 received the limited control. Comparing the assistive technology and telecare group with the control group, the hazard ratio for institutionalisation was 0.76 (95% confidence interval 0.58 to 1.01; p = 0.054). After adjusting for an imbalance in the baseline activities of daily living score between trial arms, the hazard ratio was 0.84 (95% confidence interval 0.63 to 1.12; p = 0.20). At 104 weeks, there were no significant differences between groups in health and social care resource use costs (intervention group - control group difference: mean -£909, 95% confidence interval -£5336 to £3345) or in societal costs (intervention group - control group difference: mean -£3545; 95% confidence interval -£13,914 to £6581). At 104 weeks, based on quality-adjusted life-years derived from the participant-rated EuroQol-5 Dimensions questionnaire, the intervention group had 0.105 (95% confidence interval -0.204 to -0.007) fewer quality-adjusted life-years than the control group. The number of quality-adjusted life-years derived from the proxy-rated EuroQol-5 Dimensions questionnaire did not differ between groups. Caregiver outcomes did not differ between groups over 24 weeks.

LIMITATIONS

Compliance with the assigned trial arm was variable, as was the quality of assistive technology and telecare needs assessments. Attrition from assessments led to data loss additional to that attributable to care home admission and censoring events.

CONCLUSIONS

A full package of assistive technology and telecare did not increase the length of time that participants with dementia remained in the community, and nor did it decrease caregiver burden, depression or anxiety, relative to a basic package of assistive technology and telecare. Use of the full assistive technology and telecare package did not increase participants' health and social care or societal costs. Quality-adjusted life-years based on participants' EuroQol-5 Dimensions questionnaire responses were reduced in the intervention group compared with the control group; groups did not differ in the number of quality-adjusted life-years based on the proxy-rated EuroQol-5 Dimensions questionnaire.

FUTURE WORK

Future work could examine whether or not improved assessment that is more personalised to an individual is beneficial.

The impact of assistive technology on burden and psychological well-being in informal caregivers of people with dementia (ATTILA Study)

INTRODUCTION

Assistive technology and telecare (ATT) may alleviate psychological burden in informal caregivers of people with dementia. This study assessed the impact of ATT on informal caregivers' burden and psychological well-being.

METHODS

Individuals with dementia and their informal caregivers were recruited to a randomized-controlled trial assessing effectiveness of ATT. Caregivers were allocated to two groups according to their cared-for person's randomization to a full or basic package of ATT and were assessed on caregiver burden, state anxiety, and depression. Caregivers' data from three assessments over 6 months of the trial were analyzed.

RESULTS

No significant between- or within-group differences at any time point on caregivers' burden, anxiety, and depression levels were found.

DISCUSSION

Full ATT for people with dementia did not impact caregivers' psychological outcomes compared to basic ATT. The length of follow up was restricted to 6 months.

How non-drug interventions affect the quality of life of patients suffering from progressive cognitive decline and their main caregiver

Background: In the absence of cure for age-related neurodegenerative diseases, non-drug interventions (NDIs) represent useful options. Quality of life (QOL) is a multidimensional concept progressively affected by cognitive decline. How single or multiple NDIs impact QOL is unknown.

Results: We found no significant effect of multiple over single NDI on QOL. Socio-demographic variables influenced patients’ (age, gender, caregivers’ occupational status, management of patients’ financial affairs) and caregivers’ (gender, occupational status, patients’ severity of cognitive decline) QOL. When dyads interrupted interventions after 6 months, their QOL was lower and caregivers’ anxiety, depression and physical symptoms were higher at the end of the study.

Conclusions: While the type and number of interventions do not appear to be critical, the continuity of adapted interventions in the long-term might be important for maintaining QOL of patients and caregivers.

Methods: This is a multicenter (7 Swiss Memory Clinics), quasi-experimental, one-year follow-up study including 148 subjects (mild cognitive impairment or mild dementia patients and their caregivers). Primary outcome was the effect of multiple vs single NDIs on QOL. Secondary outcome included NDIs effect on patients’ cognitive impairment and functional autonomy, caregivers’ burden, severity of patients’ neuropsychiatric symptoms and dyads’ anxiety and depression.

Investigating psychometric properties of the Thai version of the Zarit Burden Interview using rasch model and confirmatory factor analysis

Objective

The Zarit Burden Interview (ZBI) has been widely used to assess caregiver burden. Few research papers have investigated the Thai version of the ZBI. The study aimed to examine the psychometric properties of the Thai version of both the full length (ZBI-22) and short versions (ZBI-12) using Rasch analysis and confirmatory factor analysis among a sample of Alzheimer’s disease caregivers.

Results

The ZBI-22 fitted the Rasch measurement model regarding unidimensionality but not for ZBI-12. Five items from ZBI-22, and 2 items from ZBI-12 were shown to be misfitting items. Half of ZBI items were shown to be disordered category or threshold, and were locally dependent. CFA revealed three-factor and four-factor fitted the data the best for ZBI-22 and ZBI-12, respectively. Reliability was good for both forms of the ZBI (α = 0.86–0.92). Significant correlations were found with caregiver’s perceived stress, anxiety/depression, pain and mobility but not with self-care and usual activity (p > 0.05), indicating convergent and discriminant validity. To conclude, the Thai version ZBI-22, but not ZBI-12, supported the reliability and unidimensional scale among Alzheimer’s disease caregivers. Some misfitting items of the ZBI undermined the unidimensionality of the scale, and need revision.

Perceived Grief Among Caregivers of Patients With Dementia in China

Chinese family caregivers of dementia patients suffer considerable grief in their caregiving activity; little research has been conducted on dementia caregivers' grief in China. This study aims to (a) confirm the factor structure of the Mandarin version of the Marwit-Meuser Caregiver Grief Inventory-Short Form (MM-CGI-SF), (b) evaluate the levels of family caregivers' grief, and (c) explore the best predictors of family caregivers' grief. A cross-sectional study was conducted to collect data from 91 caregivers of dementia patients. The Mandarin version of the MM-CGI-SF had a three-factor structure. Family caregivers' grief was at an average level. Family caregivers' monthly household income and caring time per day predicted their own grief. The Mandarin version of the MM-CGI-SF possessed the same factor structure as the original English version, and the Chinese family caregivers experienced an average grief which was predicted by the monthly household income and caring time per day of the caregivers.

Prevalence and Risk Factors for Depression among Caregivers of Alzheimer's Disease Patients in Saudi Arabia

Objectives

To identify prevalence and risk factors of depression among caregivers of Alzheimer' disease (AD) patients.

Methods

In a cross-sectional study, 110 caregivers of AD patients participated in this study (51 males and 59 females). Patients data were obtained from patients' records at Aseer Central Hospital. Depression among caregivers was assessed by using the Hamilton Rating Scale for Depression.

Results

The age of caregivers ranged from 17 to 85 years (Mean±SD: 41.1±14.0 years). Prevalence of depression among caregivers was 70%. Caregivers were mainly sons/daughters (69.1%) or spouses (11.8%). A total of 33 caregivers (30%) had mild depression while 44 (40%) had moderate depression. Prevalence of depression was significantly higher among caregivers of AD patients who were exposed to repeated falling down (p=0.003), but did not differ significantly among caregivers who were exposed to repeated pneumonia or getting lost. Caregivers' scores of depression positively correlated with duration of caregivers' daily stay with AD patients (r=0.272, p=0.004), but did not correlate significantly with either caregivers' age or patients' age. Moreover, caregivers' depression did not differ significantly according to their marital status, educational status, employment status, or monthly income.

Conclusions

Prevalence of depression among AD caregiver is high. Risk factors for depression include patients' exposure to repeated falls and prolonged stay with patients. Therefore, psychiatric care should be provided to caregivers, home safety should be maintained to avoid falls, and several persons should interchangeably provide care to AD patients.
