Abstract

Objective

Extant literature indicates that bipolar disorder (BD) is associated with significant poor psychosocial functioning. However, the relationship between functioning and demographic and clinical variables is unclear. The aim of this study is to investigate the predictors of functioning such as demographic and clinical variables, social support, self-perceived stigma, and insight in remitted patients with BD.

Methods

Eighty patients with a diagnosis of BD, complete remission according to the criteria of Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition were included in the final assessment. Bipolar Disorder Functioning Questionnaire, Beck Depression Inventory, Young Mania Rating Scale, Internalized Stigma of Mental Illness Scale, Multidimensional Scale of Perceived Social Support, and Schedule for Assessing the Three Components of Insight were used. Student t test, Pearson correlation analyses, and linear regression analyses were used to assess the pathways effecting on functioning.

Results

The 3 predictors of functioning were severity of depression, perceived social support, and internalized stigmatization. Severity of depression is considered the strongest predictor, whereas internalized stigmatization has a core role in predicting functioning. Clinical variables such as years of education and number of hospitalization probably have indirect effects on functioning.

Conclusion

Interventions that oppose stigmatization and consideration of mild depressive symptoms will positively affect functioning in remitted patients with BD.

Introduction

According to the World Health Organization (WHO), bipolar disorder (BD) is the sixth cause of disability among all other diseases [1]. Impairment among adults with BD is not limited to symptomatic periods but persists even during periods of remission [2], [3]. After a relapse, only 40% of the patients achieve premorbid functional outcome during euthymia [4]. Thus, one of the main targets of treatment of BD should be the improvement in functioning, and in the remission period, the main outcome of the treatment should be normal level of functioning. BD is associated with profound impairment in nearly every domain of functioning [5]. It is associated with significant psychosocial, marital, interpersonal, and occupational impairment [6], [7].

Extant literature indicates that BD is associated with significant poor psychosocial functioning; however, the relationship between functioning and demographic and clinical variables is unclear and requires further examination. Therefore it is necessary to identify the factors that contribute to this disability.

Rosa et al [8] found that older age, depressive symptoms, number of previous mixed episodes, and number of previous hospitalizations predict poor functioning. In another study, the clinical variables that significantly predicted functioning were total number of episodes, number of depressive episodes, family history of psychiatric disorders, mild subdepressive symptoms, and perceived social support [9]. Wingo et al [10] found that among euthymic or mildly depressed bipolar patients, functional recovery was associated with higher education, fewer years of illness, and being married. Hajek et al [11] found decreased functioning in patients with chronic illness, history of rapid cycling type of bipolar disorder, suicidal behavior, psychiatric comorbidity, and other medical conditions such as hypothyroidism and diabetes mellitus. A recent preliminary study investigating the impact of stigma and functioning in bipolar patients demonstrates that high scores of self-perceived stigma were correlated with lower scores of functioning [12].

The aim of this study is to investigate the predictors of functioning such as demographic and clinical variables, social support, self-perceived stigma, and insight in remitted patients with BD.

Study design

This study was accomplished in the outpatient psychiatry clinic in Haydarpaşa Numune Training and Research Hospital between July 7, 2008, and November 7, 2008. Patients with a diagnosis of bipolar disorder, complete remission according to the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition were included the study. Considering their possible effects on functioning, patients with a diagnosis of mental retardation, chronic physical disease, alcohol or substance use disorder,

Results

The mean functioning (BDFQ) scores of the patients and the relationship between demographic and clinical variables with functioning are presented in Table 1, which shows that there is no relation between functioning and sex, marital status, occupation, and psychotic-featured episodes.

The correlations of demographic and clinical variables with functioning are presented in Table 2. The variables that have significant correlation with functioning were severity of depression, internalized

Discussion

In this study, the term functioning mainly expresses “social functioning,” including social withdrawal, household relations, participation in social activities, daily activities and hobbies, taking initiative and self-sufficiency, occupation, and others. Functioning has been extensively studied in schizophrenia, with less focus on remitted bipolar patients. The fact that bipolar patients struggle with serious functional loss indicates the need to study this loss and the factors related to it.
