Caregiving for Schizoprenia Patients: Personality and Anxiety Relations
ResearchGate has not been able to resolve any citations for this publication.
Duration of human life has been substantially increased in the last fifty years.
Survivals of diseases have been prolonged through the advances in medicine.
Together with these gratifying consequences, there appeared novel difficulties
to cope with. Furthermore developments including globalization,
industrialization and transition from rural to urban life occurred during the
last century; so family units became smaller and numbers of members on
employment in family units increased. As a result numbers of family members
to undertake the responsibility of care decreased. As a concept, caregiver
burden expresses physical, psychosocial and financial reactions during the
course of care providing. Distinct factors including structures of social,
cultural and family units and health care systems may affect conditions of
care. Caregiver’s age, gender, ethnicity, education, relationship with the
patient, attitude towards providing care, financial situation, coping abilities,
her own health, beliefs, social support and cultural pattern are the personal
factors that are related to perception of caregiver burden. Burden of care
giving is geared to differential aspects of care needs. For instance care needs of
physically disabled and medical care requiring patients with spinal cord
injuries may differ from care needs of chronic psychiatric disorders, demented
patients in advanced age of their lives or cancer patients in terminal periods.
Strain due to care giving may differ as a result of properties of care demands.
It is aimed to review the burden of caregivers in different medical and
psychiatric care requiring conditions and to introduce differential aspects of
caregiver burden in these different conditions.
A systematic method for clinical description and classification of both normal and abnormal personality variants is proposed based on a general biosocial theory of personality. Three dimensions of personality are defined in terms of the basic stimulus-response characteristics of novelty seeking, harm avoidance, and reward dependence. The possible underlying genetic and neuroanatomical bases of observed variation in these dimensions are reviewed and considered in relation to adaptive responses to environmental challenge. The functional interaction of these dimensions leads to integrated patterns of differential response to novelty, punishment, and reward. The possible tridimensional combinations of extreme (high or low) variants on these basic stimulus-response characteristics correspond closely to traditional descriptions of personality disorders. This reconciles dimensional and categorical approaches to personality description. It also implies that the underlying structure of normal adaptive traits is the same as that of maladaptive personality traits, except for schizotypal and paranoid disorders.
We used multiaxial structured interviews and questionnaires to evaluate the ability of self-reports on seven personality dimensions to predict independent interview diagnoses of DSM-III-R personality disorders. We studied 136 consecutive adult psychiatric inpatients, excluding those with psychosis, organic mental disorders, and severe agitation. Sixty-six patients had interview diagnoses of DSM-III-R personality disorders. Most also had mood disorders. We confirmed the hypotheses that self-reports of low self-directedness and cooperativeness strongly predicted the number of personality symptoms in all interview categories, whereas the other factors distinguished among subtypes as predicted. Self-directedness and cooperativeness also predicted the presence of any personality disorder by differentiating patients varying in risk from 11% to 94%. Patients in clusters A, B, and C were differentiated by low reward dependence, high novelty seeking, and high harm avoidance, respectively. We conclude that low self-directedness and cooperativeness are core features of all personality disorders and are validly measured by the seven-factor Temperament and Character Inventory, but not the five-factor Neuroticism-Extraversion-Openness inventory. Each DSM-III-R personality disorder category is associated with a unique profile of scores in the seven-factor model, providing an efficient guide to differential diagnosis and treatment.
Schizophrenia is highly familial neuropsychiatric disorder with heritability estimated at 60% to 90%. Even unaffected first-degree relatives of schizophrenia manifested some neuropsychologic abnormalities, neurologic soft sign, and morphologic anomalies. Because personality traits are under genetic influence and considerable heritability, we intended to evaluate temperament and character of first-degree relatives of schizophrenia and the influence of schizophrenia genetic loading on their temperament and character.
Temperament and Character Inventory was completed by 97 first-degree relatives of schizophrenia or schizoaffective disorder, 48 schizophrenic probands (44 patients with schizophrenia and 4 patients with schizoaffective disorder), and 106 control subjects. Within first-degree relatives, parents who have additional probands with schizophrenia spectrum disorder in their ascendant or collateral pedigree and siblings who have offspring with schizophrenia spectrum disorder were defined as presumed carriers (n = 20). Group differences in Temperament and Character Inventory scores were compared using a mixed-model analysis of variance with family as a random effect and age as a covariate.
Harm avoidance (HA) scores increased in the order of control subjects, the first-degree relatives, and probands. Among the relatives, presumed carriers, but not presumed noncarriers, had higher HA compared with control subjects. In addition, probands showed significantly low reward dependence, low self-directedness, and low cooperativeness scores compared with the first-degree relatives and control subjects. Probands had also higher self-transcendence scores than the first-degree relatives and had lower persistence scores than control subjects.
Our findings that HA increases in proportion to the genetic loading of schizophrenia suggest that it may be a potential endophenotype of schizophrenia.
The aim of this study was to investigate the associations between the temperament, character dimensions, and quality of life (QOL) of patients with schizophrenia; their first-degree, nonaffected relatives; and healthy control subjects. One hundred twenty patients, the same number of first-degree relatives, and the same number of control subjects were assessed using the Temperament and Character Inventory and the Quality of Life Enjoyment and Satisfaction Questionnaire. Patients were also assessed using the Positive and Negative Syndrome Scale. Patients and relatives had a significantly lower QOL than control subjects, controlled for temperament and character dimensions. Patients scored significantly higher than control subjects in harm avoidance and self-transcendence and lower in novelty seeking and self-directedness. First-degree relatives had lower results for novelty seeking and scored higher on self-transcendence than control subjects. Harm avoidance, self-directedness, and self-transcendence were the dimensions of Temperament and Character Inventory shown to be the most significant predictors of QOL. Psychopathology and age were also significant predictors of QOL. Our understanding of an individual patient's QOL must include personality evaluation.
Anxiety is common in patients undergoing radiation therapy (RT) and in their family caregivers (FCs). Little is known about individual differences in anxiety trajectories during and after RT. This study aimed to identify distinct latent classes of oncology patients and their FCs based on self-reported anxiety symptoms from the beginning to four months after the completion of RT.
Using growth mixture modeling (GMM), longitudinal changes in Spielberger State Anxiety Inventory (STAI-S) scores among 167 oncology outpatients with breast, prostate, lung, or brain cancer and 85 FCs were evaluated to determine distinct anxiety symptom profiles. STAI-S scores were assessed just prior to, throughout the course of, and for four months following RT (total of 7 assessments). Baseline trait anxiety and depressive symptoms (during and after RT) were also assessed.
The GMM analysis identified three latent classes of oncology patients and FCs with distinct trajectories of state anxiety: Low Stable (n = 93, 36.9%), Intermediate Decelerating (n = 82, 32.5%), and High (n = 77, 30.6%) classes. Younger participants, women, ethnic minorities, and those with children at home were more likely to be classified in the High anxiety class. Higher levels of trait anxiety and depressive symptoms, at the initiation of RT, were associated with being in the High anxiety class.
Subgroups of patients and FCs with high, intermediate, and low mean levels of anxiety during and after RT were identified with GMM. Additional research is needed to better understand the heterogeneity of symptom experiences as well as comorbid symptoms in patients and FCs.
Studies of patients with schizophrenia or schizophrenia spectrum disorders and general population control groups consistently show differences regarding personality dimensions. However, the profile of personality dimensions in first-degree relatives of those patients is not well understood. We used Temperament and Character Inventory to explore personality dimensions in 61 clinically stable patients with schizophrenia or schizophrenia spectrum disorders, 59 of their first-degree relatives, and 64 healthy controls. Patients scored significantly higher than controls in harm avoidance and self-transcendence and lower in self-directedness and cooperativeness. First-degree relatives showed a tendency to lower novelty seeking and self-transcendence than controls. Interpretations of these findings include the possibility that lower novelty seeking and lower self-transcendence provide a protective influence in the relatives. Further studies are needed to go into this issue in greater depth.
Quantitative endophenotypes are needed to better understand the pathogenesis of schizophrenia. The psychobiological model of temperament and character suggests that personality traits are heritable and regulated by brain systems influencing schizophrenia susceptibility. Thus, measures of temperament and character may serve as schizophrenia-related endophenotypes in individuals with schizophrenia and their non-psychotic siblings.
Individuals with schizophrenia (n=35), their non-psychotic siblings (n=34), controls (n=63), and their siblings (n=56) participated in a study of the clinical, neurocognitive and neuromorphological characteristics of schizophrenia. A mixed-model approach assessed group differences on the Temperament and Character Inventory (TCI). Neurocognitive deficits and psychopathology were correlated with the TCI. Configurations of TCI domains were examined using a generalized linear model.
Individuals with schizophrenia and their non-psychotic siblings had higher harm avoidance than controls and their siblings. Individuals with schizophrenia had lower self-directedness and cooperativeness, and higher self-transcendence than their non-psychotic siblings, controls, and the siblings of controls. Neurocognition was not related to temperament and character in individuals with schizophrenia or either control group. In non-psychotic siblings, self-directedness and cooperativeness were correlated with working memory and crystallized IQ.
Evidence supports harm avoidance as a schizophrenia-related endophenotype. An increased risk of schizophrenia may be associated with asociality (configured as high harm avoidance and low reward dependence), schizotypy (configured as low self-directedness, low cooperativeness, and high self-transcendence), and neurocognitive deficits (poor executive functioning, working/episodic memory, attention, and low IQ). The non-psychotic siblings demonstrated features of a mature character profile including strong crystallized IQ, which may confer protection against psychopathology.
Levels of stress in carers of long-term schizophrenia sufferers attending a depot clinic were assessed. Nine out of 25 carers (36%) were identified as possible or definite cases on either the GHQ or the HAD. However, a substantial proportion of carers managed to cope with the difficulties without suffering psychologically.
The Hamilton Depression Rating Scale (HDRS) is the most widely used scale for patient selection and follow-up in research studies of treatments of depression. Despite extensive study of the reliability and validity of the total scale score, the psychometric characteristics of the individual items have not been well studied. In the only reliability study to report agreement on individual items using a test-retest interview method, most of the items had only fair or poor agreement. Because this is due in part to variability in the way the information is obtained to make the various rating distinctions, the Structured Interview Guide for the HDRS (SIGH-D) was developed to standardize the manner of administration of the scale. A test-retest reliability study conducted on a series of psychiatric inpatients demonstrated that the use of the SIGH-D results in a substantially improved level of agreement for most of the HDRS items.
We identified the population of schizophrenic patients under 65 in a geographically defined area. The number using psychiatric services based on a new District General Hospital unit in the course of one year was 364, a prevalence of 2.2 per 1000 adult population. Half the patients lived in supportive private households, most often with spouses or mothers. More women than men married and retained supporters. Patients and their primary supporters were interviewed separately. The PSE Catego programme classed 47 per cent of patients as psychotic. Supporters reported disturbed behavior in 65 per cent of patients, and restricted social performance in 78 per cent. There was evidence of hardship (emotional and physical ill-health, problems with children) in 90 per cent of households. Supporters' subjective distress was directly related to the presence of psychosis and disturbed behaviour and inversely related to the duration of the illness. Drop-out and failure to take medication appeared to be causes of the relatively high prevalence of psychosis.
Personality assessment may allow reliable measurement of risk of mood disorders.
A group of adults (804) representative of the general population were assessed by questionnaire. Personality types were measured by the Temperament and Character Inventory (TCI).
Specific TCI configurations define personality types that can be described as hyperthymic, cyclothymic, irritable, and depressive. Each type had a unique profile of emotions, suicide attempts, and hospitalization.
TCI traits are associated with mood disorders.
Different ways of measuring Kraepelinean subtypes may disagree. Whether differences in personality cause psychopathology, or vice versa, remains uncertain.
Personality profiles help in assessing suicidality and planning treatment.
This study used a stress and coping framework to examine family members' emotional adjustment to caring for a patient with a first episode of schizophrenia.
One family member providing primary assistance to each of 63 patients with a first episode of schizophrenia or schizoaffective disorder was interviewed shortly after patient hospitalization.
Overall, family members showed evidence of reasonably good emotional adjustment. Select indices of poorer emotional adjustment by family members were linked to (i) attributions in which the patient's psychiatric problems were viewed as a result of the patient's moral failings or psychological problems from earlier life, (ii) coping that was avoidant and (iii) patient management strategies that involved conflict avoidance and authoritarianism/reasoning.
These findings are consistent with psychoeducational interventions that educate family members about psychiatric illness and assist them in their efforts to cope with and manage patient problems at home.
Expressed emotion (EE) is a measure of the family environment that is a well replicated psychosocial predictor of psychiatric relapse. Theoretical models of EE place heavy emphasis on the notion of control. We explored the extent to which high and low EE relatives made both attributions of control about patients and engaged in controlling behaviours.
Trained raters who were blind to information about EE coded interviews with 35 relatives of patients with schizophrenia and 42 relatives of patients with unipolar depression. Relatives were rated on two reliable scales that assessed relatives' tendencies to make illness controllability attributions and relatives' efforts to exert direct behavioural control over patients.
In both the schizophrenia and depressed groups, high-EE relatives attributed more control to their ill family members than did low EE relatives. They also behaved in a more controlling manner. Examination of patients' clinical outcomes during a 9-month follow-up period revealed that high levels of behavioural control on the part of relatives significantly predicted relapse in patients with schizophrenia but not in patients with depression.
These findings support the attribution-based model of EE. They further suggest that controlling behaviours on the part of relatives may mediate the EE-relapse link in schizophrenia. Such behaviours may be important targets for modification in family-based interventions for schizophrenia.
An earlier study explored the influence of psychosocial variables (family coping behaviors, family psychological distress, family social support, and patient behavioral problems) on family functioning in 58 families providing care for a family member with schizophrenia. The purpose of this article is to explore what living with schizophrenia is like for families by conducting a thematic analysis of the qualitative data they provided during the study. Five recurrent themes were identified in the analysis of the qualitative data: overwhelming feelings, importance of medication, legal system difficulties, family and friends, and mental health professionals.
Previous findings indicated that schizophrenia patients might have a different personality structure from the general population on several dimensions of temperament and character. Some authors proposed that HA might be a marker of underlying genetic vulnerability to schizophrenia. Studies on high-risk subjects and first degree relatives of patients is essential to test the value of a measure as a marker of genetic vulnerability to a disease. Few studies tested the biopsychosocial model of personality on unaffected relatives of schizophrenia.
We compared the Temperament and Character (TCI) profiles of 94 first degree relatives of schizophrenia and 75 controls. We also investigated the relationship between schizotypy and TCI dimensions in the study sample.
The harm avoidance scores of the relatives of schizophrenia patients with schizotypal features were significantly higher. Self transcendence scores were also significantly higher among relatives with schizotypal features. In contrast, the relatives of the patients with schizophrenia who did not have schizotypal features had higher SD and C scores than the control group.
This finding is consistent with the previous findings which suggested harm avoidance as a vulnerability indicator of schizophrenia. Some character features like self transcendence might be also associated with schizotypal features.
Stigmatization of people with mental illness has been investigated in numerous studies. Little research, however, has been done to explore how relatives of people with schizophrenia perceive and experience stigmatization and how they can fight such stigmatization.
Aiming to explore stigma from the perspective of relatives of people with schizophrenia, focus group interviews were conducted with 122 members of advocacy groups from different parts of Germany. Focus group sessions were tape- and video-recorded and transcribed. Transcripts were coded using an inductive method, generating categories (domains) from the material.
The analysis of focus group data shows that, contrary to previous research findings, discrimination and disadvantages encountered by relatives of schizophrenia patients reach far beyond the spheres of direct social interaction and access to social roles. Our study revealed two additional domains in which relatives encounter stigmatization: structural discrimination and public images of mental illness. Furthermore, psychiatry has been identified as one important source of stigma. Relatives also suggested numerous anti-stigma interventions. These can be grouped into five main categories: communication measures, support for the ill and their relatives, changes in mental health care, education and training, and control and supervision.
Based on our findings,ways of how relatives of schizophrenia patients and mental health professionals can fight against stigma are discussed.
