Understanding family variables in outcome research in schizophrenia

Associations of living arrangements with symptoms and functioning in schizophrenia

BACKGROUND

Living arrangements and accommodation are closely related, but no study had concurrently investigated their associations with outcomes in schizophrenia. This study seeks to describe and compare socio-demographic, clinical and functioning profiles of people with schizophrenia in different living arrangements and accommodation, and to examine the associations of living arrangements and accommodation with symptomatic remission and functioning.

METHODS

Community dwelling outpatients with schizophrenia (n = 276) were inquired on living arrangements, accommodation, socio-demographics and assessed on the Positive and Negative Syndrome Scale (PANSS) and the Social and Occupational Functioning Scale (SOFAS). Socio-demographics, symptoms and functioning of outpatients in different living arrangements and accommodation were compared. Symptomatic remission was investigated using logistic regression with living arrangements, socio-demographics and clinical variables as independent variables. Functioning was investigated using multiple regression with the same set of independent variables and the addition of PANSS factors. The same analyses were conducted with accommodation as independent variable.

RESULTS

185 (67.03%) participants lived with family and 195 (70.65%) participants lived in owned accommodation. People living with their spouses had significantly higher SOFAS, lower PANSS Total and PANSS Positive than people living with family, independently, or in rehabilitation centres. They also had lower PANSS Negative than people living with family and a higher likelihood to have achieved symptomatic remission. Types of accommodation was not associated with symptoms, symptomatic remission, and functioning.

CONCLUSION

Living arrangements, but not types of accommodation, were associated with symptoms and functioning in schizophrenia. Family education and support is important to help maintain a conducive environment for people with schizophrenia. People living independently may need more support.

Staff training in cognitive-behavioral family intervention in mental illness using the multiple-family group approach: a pilot study

This article describes a pilot project in which eight Community Mental Health Centre staff were trained in a cognitive-behavioral intervention for families of 37 mentally ill clients. After involvement in training, the staff demonstrated more regular inclusion of family members in routine clinical practice, and a trend towards an increase in relevant knowledge. After involvement in the program, the families experienced a decrease in burden (Family Burden Interview Schedule) even though the primary clients' functioning (Global Assessment of Functioning) did not change. The results are encouraging, indicating that it is possible to train staff in ordinary clinical settings in effective cognitive-behavioral family interventions. The findings need to be replicated in a controlled study with larger samples.

A study of expressed emotion in the parental primary carers of adolescents with intellectual impairment

Expressed emotion (EE) was measured in the parental primary carer (carer) of 92 adolescents with intellectual impairment to examine its associated characteristics. High EE was mainly a result of high levels of emotional overinvolvement. High EE was associated with psychological illhealth, poor-quality marriage and poor practical social support of the carer, and psychiatric disorder in the adolescent with intellectual impairment. This suggests that EE may be a useful indicator of coping difficulties in these families. The subgroup of high EE emotional overinvolvement was associated with a carer with more psychological illhealth, a worse-quality marriage, less practical social support, greater professional support and an insecure style of respite care usage for an adolescent of greater intellectual impairment. The subgroup of criticism have an adolescent of less severe intellectual impairment, more behavioural disturbance and yet the carer has less professional support. Appreciation of the quality of the relationship of the carer with their dependent family member may enable greater understanding of how to improve the quality of life for both the carer and the cared for.

Contribution of family, cognitive and clinical dimensions to long-term outcome in schizophrenia

A multivariate approach incorporating both biological and psychosocial factors was used in a cross-sectional study of schizophrenic inpatients and outpatients selected to represent opposite ends of the outcome spectrum. Twenty-six RDC-diagnosed chronic schizophrenic patients hospitalized continuously for 18 months or longer, and 26 patients with a history of at least three years of community tenure without rehospitalization were matched for sex, age, ethnicity, SES and chronicity, and assessed on a structured family interview (Social Behavior Assessment Schedule), neuropsychological test battery, Brief Psychiatric Rating Scale and Premorbid Asociality Scale. Stepwise discriminant function analysis was performed; family ratings of patients' problem behaviors was the most powerful discriminator between the two groups and a composite measure of neuropsychological functioning ranked second. Other significant discriminators were BPRS scores, availability of social support to the family and age of onset. Family ratings of patient behavior were related to ratings of family burden and to BPRS scores. Further research is needed to understand the complex interactions between the diverse sets of social, clinical and neurobiological factors that determine long-term outcome in schizophrenia.
