EMOTIONAL BURDEN IN CAREGIEVERS of PATIENTS WITH OBSESSIVE-COMPULSIEVE DISORDER

The objective of this study was to evaluate the emotional burden, psychological morbidity, and level of family accommodation in caregivers of obsessive-compulsive disorder (OCD) patients, according to sociodemographic and clinical factors. Methods: Fifty Brazilian DSM-IV OCD patients and their caregivers were evaluated using the Family Accommodation Scale, the Zarit Burden Interview (ZBI), the Self-Report Questionnaire (caregivers), the Yale-Brown Obsessive-Compulsive Scale, and the Beck Depression Inventory (patients). Most caregivers (80%) were aged between 30 and 59 years and lived with the patient (88%). Results: Forty-two percent presented a common mental disorder and their mean ZBI score was 28.9. Family accommodation was moderate in 26% and severe or very severe in 24%. Caregivers' levels of psychological morbidity, accommodation, and emotional burden were associated with each other and with the severity of patient obsessive-compulsive and depressive symptoms. Conclusions: The results suggest that caregivers of OCD patients have important levels of burden and psychological morbidity and should receive orientation and support to minimize this emotional impact.

Assessing the health outcomes of the family members of disabled individuals

The health utilization and death rates were captured for the family members of disabled individuals over a fifteen-year period to determine if exposure to disability in the family manifests poor health outcomes. Data from the Newfoundland Adult Health Survey (1995) was linked to fifteen years, 1995- 2010, of provincial health administrative data including hospital data, physician claims, and death records from the provincial health care system. The health records and survey data were analyzed in relation to the disability exposure burden experienced when a family member is disabled. The level of disability exposure burden was quantified based on the addition of individual disability scores for each family member. Disability exposure burden was associated with increased number of hospital separations, total hospitalization days and the number of physician visits, both General Practitioner and Specialist (p<0.1) but there was no association between death (p>0.1) and disability exposure burden. Family members of disabled individuals experienced increased rates of hospital separations, hospitalization days, and physician visits suggesting that deleterious health outcomes may be introduced when individuals are exposed to disability in the family unit.

Sobrecarga vivenciada por familiares cuidadores de pacientes esquizofrénicos e sua relação com a depressão

RESUMO: A partir da desinstitucionalização psiquiátrica, a ênfase nas políticas públicas de saúde mental passou para os serviços comunitários e para períodos mais curtos de hospitalização. As famílias, então, tornaram-se as principais provedoras de cuidados cotidianos e de apoio aos pacientes. As dificuldades e o despreparo em assumir este novo papel têm gerado um sentimento de sobrecarga nos familiares, o que pode afetar sua saúde física e mental. Vários estudos investigaram as consequências de se tornar um cuidador de um paciente psiquiátrico, mas poucos pesquisaram o impacto na saúde mental desses cuidadores. A presente pesquisa investigou a relação entre a sobrecarga e a saúde mental dos familiares cuidadores de pacientes psiquiátricos. Participaram deste estudo 74 familiares cuidadores de pacientes com diagnóstico de esquizofrenia, atendidos no ambulatório do Serviço de Referência em Saúde Mental, da cidade de Divinópolis, MG. Os familiares participaram de uma entrevista estruturada. Nela foram aplicadas a Escala de Avaliação da Sobrecarga dos Familiares de Pacientes Psiquiátricos (FBIS-BR) e, para avaliar a saúde mental dos cuidadores, a Escala de Depressão de Beck (BDI). Foram realizadas análises estatísticas descritivas, univariadas e multivariadas. Os resultados mostraram que a maioria dos cuidadores era do sexo feminino (78,40%), pais (62,20%) e com idade média de 59,14 anos. Os cuidadores apresentaram uma média de sobrecarga global objetiva de 2,05 (DP ± 0,54), em uma escala de 1 a 5 pontos, e uma média de sobrecarga global subjetiva de 2,44 (DP ± 0,71), em uma escala de 1 a 4 pontos. Os resultados da escala BDI mostraram que 42 cuidadores poderiam ser classificados com depressão mínima (56,80%), 17 com depressão leve (23,00%), 7 com depressão moderada (9,50%) e 8 com depressão grave (10,80%). Foram encontradas correlações positivas significativas entre o grau de sobrecarga global e das subescalas e o nível de depressão. As análises multivariadas mostraram que o principal preditor de depressão dos cuidadores foi a sobrecarga global subjetiva. Outros preditores foram a obrecarga objetiva das rotinas diárias e da supervisão dos comportamentos problemáticos dos pacientes e a sobrecarga subjetiva das preocupações com o paciente. As informações levantadas mostraram o impacto do papel de cuidador na saúde mental dos familiares e apontaram para a necessidade de uma maior atenção, por parte dos gestores e profissionais da área, aos cuidadores de pacientes psiquiátricos.----------ABSTRACT: The emphasis in public policy on mental health was transferred to community services and for shorter periods of hospitalization from the psychiatric deinstitutionalization. Then the families become the first provider of daily care and support to patients. The difficulties and unprepared to assume this new role has generated a sense of overload in the relatives, which can affect your physical and mental health. Several studies have investigated the consequences of becoming a caregiver of a psychiatric patient, but few scholars have researched the impact on the mental health of caregivers. The present study has investigated the relationship between overload and mental health of family caregivers of psychiatric patients. The study included 74 family caregivers of patients with schizophrenia and outpatient clinic of the Department of Mental Health Reference, in Divinópolis, Minas Gerais, Brazil. The Rating Scale Burden of Relatives of Psychiatric Patients and the scale of Beck Depression Inventory (BDI) to assess the mental health of caregivers were applied in the interview. Descriptive statistics and univariate and multivariate analysis have performed. The results showed that the majority of caregivers were female (78.40%), parents (62.20%) and mean age of 59.14 years. The caregivers had an average burden overall objective of 2.05 (± 0.54) on a scale of 1 to 5 points, and a subjective global average burden of 2.44 (± 0.71) in a scale of 1 to 4 points. The results of the BDI showed that 42 caregivers could be classified with minimal depression (56.80%), 17 with mild depression (23.00%), 7 with moderate depression (9.50%) and 8 with severe depression (10 80%). Significant positive correlations were found between the degree of overloading and global subscales and depression levels. Multivariate analysis showed that the main predictor of caregivers' depression was the global subjective burden. Other predictors were the objective burden of daily routines and supervision of problem behaviors of patients and subjective burden of the concerns about patient. The resulting information showed the impact of caregiver role in the mental health of relatives and pointed to the need for higher attention of managers and professionals to caregivers of psychiatric patients.

Sobrecarga no cuidar e suas repercussões nos cuidadores de pacientes em fim de vida : Revisão sistemática da literatura

Cuidar de um familiar com doença avançada e/ou em fim de vida pode representar uma grande sobrecarga emocional, física e financeira que afeta a qualidade de vida dos cuidadores. O presente estudo teve como objetivo realizar uma revisão sistemática da literatura sobre a sobrecarga no cuidar, os fatores relacionados e suas consequências nos cuidadores de pacientes com câncer avançado em fim de vida ou em cuidados paliativos. Foi realizada uma busca de artigos científicos publicados nas bases de dados EBSCO, Web of Knowledge e Bireme, desde os primeiros registros nas respectivas bases de dados sobre o tema até março de 2014. Dos 582 artigos encontrados, apenas 27 foram selecionados. A maioria dos artigos afirma que os cuidadores familiares estão sobrecarregados. Em alguns estudos, a sobrecarga no cuidar aparece associada a características do paciente e da sua doença; em outros, a um pior estado de saúde do cuidador, a uma maior sintomatologia psicopatológica (ansiedade, depressão, distress emocional) e também ao desenvolvimento de complicações no luto. Porém, a esperança, o apoio social, a capacidade do cuidador de atribuir um significado à experiência de cuidar e se sentir confortável com as tarefas de cuidar foram associados a menores níveis de sobrecarga.

Cortisol, family coping and burden in informal caregivers of addicts

This study focuses on the prospective mediation role of family coping between burden and cortisol levels in informal caregivers of addicts as well as on the feasible use of two different ways to analyse the salivary cortisol levels. Participants were 120 Portuguese informal caregivers of addicts. The cortisol samples were collected at awakening, 45 minutes later and after a 30 minute presentation of images taken from the International Affective Picture System. Family coping and caregiver burden were measured using the Portuguese versions of the Caregiver Reaction Assessment, and the Family Crisis Oriented Personal Evaluation Scale. Cortisol samples were collected in salivettes and the results were computed in order to determine the Area Under the Curve scores (AUCg, AUCi). Results found family coping to be negatively correlated with burden and AUCg levels (i.e. overall intensity) and positively correlated with either AUCg and AUCi (i.e. change over time). The mediation model revealed that family coping was a partial mediator in the relationship between the burden and AUCg levels. Therefore, Family Coping appears to be an essential variable in understanding the stress response and should be considered in further studies and interventions. In addition, the use of two different formulas for calculating cortisol levels provided important new information concerning the relationship between cortisol, burden and family coping. It seems that burden has a more profound effect on the overall intensity of the neuroendocrine response to caregiver stress and not so much on the sensitivity of the system.

Burden in family caregivers of the elderly: prevalence and association with characteristics of the elderly and the caregivers

A cross-sectional, epidemiological study aimed to estimate the prevalence of burden among family caregivers of impaired elderly residents in the city of João Pessoa, and to identify associations between the mean burden and social and demographic characteristics of the elderly and the caregivers. A total number of 240 elderly residents in a previously drawn census tract participated in this research. The sample was composed of 52 elderly and their caregivers. For data collection, a questionnaire was applied with questions on social and demographic characteristics of elderly and caregivers, and the Burden Interview Scale was used. Results showed a high prevalence of burden among caregivers (84.6%), in which a statistically significant association was found with the following characteristics: retired elderly, elderly as head of family, spousal caregivers, and caregivers with less education. The findings of this study may contribute to the development of activities focused on formal and emotional support for the caregivers.

Family burden related to clinical and functional variables of people with intellectual disability with and without a mental disorder

Few studies have been found that to assess the factors that explain higher levels of familyburden in adults with intellectualdisability (ID) and intellectualdisability and mental disorders (ID-MD). The aims of this study were to assess familyburden in people with ID and ID-MD and to determine which sociodemographic, clinical and functionaldisabilityvariables account for familyburden. The sample is composed of pairs of 203 participants with disability and their caregivers, of which 33.5% are caregivers of people with ID and 66.5% of ID-MD. Assessments were performed using scales of clinical and functionaldisability as the following instruments: Weschler Adult Intelligence Scale-III (WAIS-III), Inventory for Client and Agency Planning (ICAP), Psychiatric Assessment Schedule for Adults with Development Disability (PAS-ADD checklist), Disability Assessment Schedule of the World Health Organization (WHO-DAS-II) and familyburden (Subjective and Objective FamilyBurden Inventory - SOFBI/ECFOS-II). People with ID-MD presented higher levels of functionaldisability than those with ID only. Higher levels of familyburden were related to higher functionaldisability in all the areas (p < 0.006-0.001), lower intelligence quotient (p < 0.001), diagnosis of ID-MD (p < 0.001) and presence of organic, affective, psychotic and behavioral disorders (p < 0.001). Stepwise multiple regression showed that behavioral problems, affective and psychotic disorder, disability in participation in society, disability in personal care and presence of ID-MD explained more than 61% of the variance in familyburden. An integrated approach using effective multidimensional interventions is essential for both people with ID and ID-MD and their caregivers in order to reduce familyburden.

An Infant with Food Allergy and Eczema in the Family – The Mental and Economic Burden of Caring

Allergic diseases including food allergy and eczema in an infant in combination with the everyday activities of caring for a family will pose challenges to parents. Only fragments of these challenges are revealed to health care professionals. Families have varying mental, social and economic resources to help them care for an allergic infant, and all such resources are important in determining how families succeed in meeting these challenges and the quality of the infant’s care. This study evaluated the whole burden to the family caused by an infant's allergic disease during the first 24 months of life. As the primary caregiver during this period is usually the mother, her perspective was considered important. Ecocultural theory, which considers families as capable of modifying the positive and negative forces facing them, was taken as the frame of reference. Data were collected as part of an ongoing prospective mother-infant study, and the methods included severity scoring of atopic dermatitis, dietary records, health-related quality of life measurements and assessments of the use of health care services and medications for treating the infant’s eczema, food allergy and asthma. Interviews with mothers were analysed by deductive content analysis on the basis of ecocultural theory and the family empowerment model. The theme “Living an ordinary family life” guided the organization of family activities essential for treating the infant's food allergy and eczema. These activities were sources of both strain and support for the mothers, the allergy-related supporting factors being the mother’s own knowledge of the allergy, hopes for an improvement in the infant’s condition, social support and work. An infant’s food allergy at the age of one year caused considerable strain for the mother in cases where the introduction of new foods into the child’s diet was delayed. This delay was still causing the mother additional strain when the child was 24 months of age. The infants waking at night at the ages of 12 and 24 months because of itching related to eczema caused strain for the mothers. The infants’ health-related quality of life was impaired at ages of 6 and 12 months compared with healthy infants. The principal reasons for impairments were itching, scratching and sleep disturbances at 6 and 12 months and treatment difficulties at 6 months. Problems with getting to sleep were reported at all stages irrespective of eczema and were also present in healthy infants. The economic impact of the treatment of allergic diseases on families during the first 24 months was 131 EUR (2006 value) in cases of eczema and 525 EUR in cases of food allergy. From the societal perspective, the costs of food allergy were a median of 3183 EUR (range 628–11 560 EUR) and of eczema a median of 275 EUR (range 94–1306 EUR). These large variations in costs in food allergy and eczema indicate that disease varies greatly . In conclusion, food allergy and eczema cause extra activities and costs to families which arrange these disease-related activities in such a way that they support the leading family theme “Living an ordinary family life”. Health care professionals should consider this thematic character of family life and disease-related activities in order to ensure that new treatments are sustainable, meaningful and tailored to daily activities. In addition, those mothers who are experiencing difficulties with food allergic infants or infants with eczema should be recognized early and provided with individual encouragement and support from health clinics. In the light of the present results, early detection of symptoms and effective parental guidance can contribute to the well-being and health-related quality of life of the child and family.

Dimensional analysis of burden in family caregivers of patients with obsessive-compulsive disorder

Aims: Obsessivecompulsive disorder (OCD) also generates emotional burden in the patient's family members, but no study has evaluated the specific dimensions of burden. The objectives were to evaluate the dimensions of the Zarit Burden Interview (ZBI) and possible correlates. Methods: This was a cross-sectional study involving 47 patients and 47 caregivers, using a sociodemographic questionnaire; the ZBI; the Self Reporting Questionnaire; the Family Accommodation Scale; and the YaleBrown ObsessiveCompulsive Scale. The ZBI factor analysis was conducted using Varimax Rotation. Results: Six factors were identified, explaining 74.2% of the total variance: factor 1, interference in the caregiver's personal life (36.6% of the variance); factor 2, perception of patient's dependence (10.8%); factor 3, feelings of irritation or intolerance (9.2%); factor 4, guilt (7.2%); factor 5, insecurity (5.6%); and factor 6, embarrassment (4.8%). The six ZBI factors were associated with greater OCD severity and with greater accommodation to the patient's symptoms, and factors 1, 2, 5 and 6 with caregiver's psychological morbidity. Caregiver's sex (female) was associated with factors 5 and 6, relationship with the patient (being a parent or son/daughter) with factor 5, higher educational level with factor 6, living with the patient with factor 3, worse self-evaluation of health with factors 1, 5 and 6, and occupational status (not working) with factors 1, 2, 5 and 6. Conclusion: The dimensions of burden identified indicate the most affected aspects of a caregiver's life and could guide the planning of more specific interventions. Thus, the caregiver could participate more effectively in the OCD patient's treatment, with a lower impact on his/her life.

Burden of maternal bipolar disorder on at-risk offspring: A controlled study on family planning and maternal care

Introduction: Bipolar disorder (BD) is a highly incapacitating disease typically associated with high rates of familial dysfunction. Despite recent literature suggesting that maternal care is an important environmental factor in the development of behavioral disorders, it is unclear how much maternal care is dysfunctional in BD subjects. Objective: The objective of this study was to characterize maternal care in DSM-IV/SCID diagnosed BD type I subjects compared to healthy controls with (PD) and without (NPD) other psychiatric diagnoses. Materials and methods: Thirty-four BD mothers and 106 controls underwent an interview about family planning and maternal care, obstetrical complications, and mother-child interactions. K-SADS-PL questions about violence exposure were used to ascertain domestic violence and physical/sexual abuse. Results: BD mothers were less likely to have stable unions (45.5%; p < 0.01) or to live with the biological father of their children (33.3%; p < 0.01), but had higher educational level and higher rates of social security use/retirement. They also had fewer children and used less contraceptive methods than controls. Children of BD women had higher rates of neonatal anoxia, and reported more physical abuse (16.1%; p = 0.02) than offspring of NPD mothers. Due to BD mothers' symptoms, 33.3% of offspring suffered physical and/or psychological abuse. Limitations: Post hoc analysis, and the use of questions as a surrogate of symptoms as opposed to validated instruments. Conclusion: This is one of few reports confirming that maternal care given by BD women is dysfunctional. BD psychopathology can lead to poor maternal care and both should be considered important environmental risk factors in BD, suggesting that BD psychoeducation should include maternal care orientation.

An evaluation of a family psychoeducation program in community mental health

The aim of the research project was to identify the efficacy of the family psychoeducation program as a strategy for reducing the hospital admissions of young people. It also aimed to determine if the family psychoeducation program had an impact on the experience of caregiving and knowledge and satisfaction of services provided by the mental health service. A retrospective chart audit compared readmission history of 27 clients whose families attended a psychoeducation program with readmission history of a matched group of young people whose families did not attend the program. A telephone survey was conducted for both groups of families to investigate knowledge and understanding of services and burden of care. The results indicated that family participation in a brief multiple family psychoeducation program did not reduce the number or duration of admissions of the young people. There was no impact on the level of care for families who attended the psychoeducation program, however, this group showed some evidence of increased knowledge and understanding of services as compared to the control group.

Lower Atherosclerotic Burden in Familial Abdominal Aortic Aneurysm

OBJECTIVE: Despite the apparent familial tendency toward abdominal aortic aneurysm (AAA) formation, the genetic causes and underlying molecular mechanisms are still undefined. In this study, we investigated the association between familial AAA (fAAA) and atherosclerosis. METHODS: Data were collected from a prospective database including AAA patients between 2004 and 2012 in the Erasmus University Medical Center, Rotterdam, The Netherlands. Family history was obtained by written questionnaire (93.1% response rate). Patients were classified as fAAA when at least one affected first-degree relative with an aortic aneurysm was reported. Patients without an affected first-degree relative were classified as sporadic AAA (spAAA). A standardized ultrasound measurement of the common carotid intima-media thickness (CIMT), a marker for generalized atherosclerosis, was routinely performed and patients' clinical characteristics (demographics, aneurysm characteristics, cardiovascular comorbidities and risk factors, and medication use) were recorded. Multivariable linear regression analyses were used to assess the mean adjusted difference in CIMT and multivariable logistic regression analysis was used to calculate associations of increased CIMT and clinical characteristics between fAAA and spAAA. RESULTS: A total of 461 AAA patients (85% men, mean age, 70 years) were included in the study; 103 patients (22.3%) were classified as fAAA and 358 patients (77.7%) as spAAA. The mean (standard deviation) CIMT in patients with fAAA was 0.89 (0.24) mm and 1.00 (0.29) mm in patients with spAAA (P = .001). Adjustment for clinical characteristics showed a mean difference in CIMT of 0.09 mm (95% confidence interval, 0.02-0.15; P = .011) between both groups. Increased CIMT, smoking, hypertension, and diabetes mellitus were all less associated with fAAA compared with spAAA. CONCLUSIONS: The current study shows a lower atherosclerotic burden, as reflected by a lower CIMT, in patients with fAAA compared with patients with spAAA, independent of common atherosclerotic risk factors. These results support the hypothesis that although atherosclerosis is a common underlying feature in patients with aneurysms, atherosclerosis is not the primary driving factor in the development of fAAA.

The influence of burden of care and perceived stigma on expressed emotions of relatives of stable persons with schizophrenia in Nigerian semi-urban/urban settings

RESUMO: Schizophrenia’s burden defines experience of family members and is associated with high level of distress. Courtesy stigma, a distress concept, worsens caregivers’ burden of care and impacts on schizophrenia. Expressed emotion (EE), another family variable, impacts on schizophrenia. However, relationship between EE, burden of care and stigma has been little explored in western literature but not in sub-Saharan Africa particularly Nigeria. This study explored the impact of burden of care and courtesy stigma on EE among caregivers of persons with schizophrenia in urban and semi-urban settings in Nigeria. Fifty caregivers each from semi-urban and urban areas completed a socio-demographic schedule, family questionnaire, burden interview schedule and perceived devaluation and discrimination scale. The caregivers had a mean age of 42 (± 15.6) years. Majority were females (57%), married (49%), from Yoruba ethnic group (68%), monogamous family (73%) and Christians (82%). A higher proportion of the whole sample (53%) had tertiary education. Three out of ten were sole caregivers. Seventy three (73%) lived with the person they cared for. The average number of hours spent per week by a caregiver with a person with schizophrenia was 35 hours. The urban sample had significantly higher proportion of carers with high global expressed emotion (72.7%) than the semi-urban sample (27.3%). The odds of a caregiver in an urban setting exhibiting high expressed emotion are 4.202 times higher than the odds of caregiver in a semi-urban setting. Additionally, there was significance difference between the urban and semi-urban caregivers in discrimination dimension. High levels of subjective and objective burden were associated with high levels of critical comments. In conclusion, this study is the first demonstration of urban-semi-urban difference in expressed emotion in an African country and its findings provide further support to hypothesized relationship between components of EE and burden of care.

Burden experienced by families of patients with schizophrenia and its related factors

RESUMO: Objetivo: Este estudo teve como objetivo avaliar a carga dos cuidadores de doentes com Esquizofrenia e avaliar a correlação com determinadas características demográficas dos doentes e dos cuidadores, assim como com o nível de emoção expressa na família. Métodos: Este estudo descritivo-analítico foi realizado em 172 doentes com Esquizofrenia e seus cuidadores primários, que foram selecionados em ambulatório, a partir da consulta externa do Hospital Psiquiátrico em Teerão, no Irão, mediante uma amostra de conveniência. Os cuidadores foram entrevistados utilizando as escalas Zarit Burden Interview e Family Questionnaire, de forma a avaliar a sobrecarga sentida pelos cuidadores e o nível de emoção expressa na família, respectivamente. Os dados foram analisados por meio de testes de Mann-Whitney, Kruskal-Wallis, e Spearman. Resultados: O nível de sobrecarga vivenciada pela maioria dos cuidadores primários foi moderada a grave. A pontuação obtida nas sub-escalas de comentários emocionais, envolvimento excessivo e comentários críticos foram maiores do que o ponto de corte em 51,7% e 64,5% dos cuidadores, respectivamente. Os resultados mostraram que as pontuações obtidas nas duas subescalas do questionário família tinham uma correlação significativa e direta com a carga experimentada pelos cuidadores. O nível de carga experimentada pelos cuidadores foi significativamente diferente entre os grupos de idade e estado civil dos cuidadores, e género, status ocupacional e estado civil dos doentes. O número de membros da família, as condições 5 de alojamento, o tempo gasto pelo cuidador com o paciente diariamente, o nível de renda familiar e a duração da doença afetaram significativamente o nível de carga experimentada pelo cuidador. Conclusão: Com base nos resultados, alguns fatores demográficos dos cuidadores, pacientes e seus familiares afetam significativamente a carga experimentada pelos cuidadores primários. A maioria das famílias dos pacientes têm alto nível de emoção expressa e existe uma significativa associação direta entre as emoções expressas e a carga experimentada.------------ABSTRACT: Aim: This study aimed to assess the burden experienced by the caregiver of patients with Schizophrenia, and evaluate its correlation with some demographic characteristics of patients, their caregivers, and the level of expressed emotion in the family. Methods: This descriptive-analytic study was conducted on 172 schizophrenic patients and their primary caregivers selected from the outpatient clinic of a mental hospital in Tehran, Iran using convenience sampling. Caregivers were evaluated with Zarit Burden Interview and Family Questionnaire to assess the burden experienced by the caregivers and the level of expressed emotion in the family, respectively. Data were analyzed using Mann-Whitney, Kruskal-Wallis, and Spearman’s tests. Results: The level of burden experienced by the majority of primary caregivers was moderate to severe. The scores obtained in the subscales of emotional over-involvement and critical comments were higher than the cutoff point in 51.7% and 64.5% of caregivers respectively. The results showed that the scores obtained in the two subscales of family questionnaire had a significant, direct correlation with the burden experienced by the caregivers. The level of burden experienced by the caregivers was significantly different between the subgroups of age and marital status of the caregivers, and gender, occupational status and marital status of the patients. Number of family members, home ownership status, time spent by the caregiver with the patient daily, level of family income and duration of disorder significantly affected the level of burden experienced by the caregiver. Conclusion: Based on the results, some demographic factors of the primary caregivers, patients and their family significantly affect the burden experienced by the primary caregivers. Most of the families of patients have high expressed emotions and a significant, direct association exists between the expressed emotions and the burden experienced.
