Expressed emotion of families and the course of mood disorders: a cohort study in Japan

Family psychoeducation for major depressive disorder - study protocol for a randomized controlled trial

Background

Major depressive disorder has been shown to affect many domains of family life including family functioning. Conversely, the influence of the family on the course of the depression, including the risk of relapse, is one reason for targeting the family in interventions. The few studies conducted within this area indicate that family psychoeducation as a supplement to traditional treatment can effectively reduce the risk of relapse in patients with major depression as well as being beneficial for the relatives involved. However, the evidence is currently limited. This study will investigate the effect of family psychoeducation compared to social support on the course of the illness in patients with major depressive disorder.

Method/design

The study is designed as a dual center, two-armed, observer-blinded, randomized controlled trial. Relatives are randomized to participate in one of two conditions: either four sessions of manualized family psychoeducation or four sessions in a social support group led by a health care professional. Patients will not participate in the groups and will continue their treatment as usual. A total of 100 patients, each accompanied by one relative, will be recruited primarily from two outpatient clinics in the Capital Region of Denmark.

The primary outcome is the occurrence of depressive relapse at 9-month follow-up defined as a score ≥7 on the Hamilton six-item subscale. Secondary outcomes will include time to relapse.

Discussion

It is hoped that the results from this study will help to clarify the mechanisms behind any beneficial changes due to family psychoeducation and provide information on the long-term effect of this intervention for both patient and relatives. If the results are positive, the family psychoeducation program may be suitable for implementation within a clinical setting.

Psychoeducation for major depressive disorders: a randomised controlled trial

Various psychological therapies have been shown to be effective for the treatment of mood disorders. Among them, family psychoeducation has demonstrated efficacy in reducing symptom severity and extending the time to relapse. We tested the efficacy of adding psychoeducation focussed on how to deal with the family's expressed emotion to treatment as usual (TAU) to prevent relapse among patients with remitted major depression. A total of 34 patients with major depressive disorders in full or partial remission were randomised to receive either group psychoeducation over six sessions, each consisting of a didactic lecture and group problem-solving (n=19), plus TAU or TAU alone (n=15). The primary outcome was relapse by Diagnostic and Statistical Manual of Mental Disorders fourth edition (DSM-IV) criteria. Masked raters administered the Hamilton Rating Scale for Depression-17 (HRSD-17). As many as 18 patients in the intervention group and 14 patients in the control group completed the study. Time to relapse was significantly longer in the intervention group than in the control group, with a risk ratio (RR) of relapse by 9 months of 0.12. At 9 months, there was a significantly greater decrease in the HRSD-17 score in the intervention group than in the control group. We demonstrated the effectiveness of patient psychoeducation on the course and outcome of major depressive disorders.

A 'family affair'? The impact of family psychoeducational interventions on depression

Major depressive disorder is reported to be the most common mental disorder, and one of the leading causes of disability-adjusted life years. It causes high levels of family burden and of expressed emotions. Research interest in family functioning in mental disorders has recently shifted from schizophrenia to unipolar and bipolar affective disorders. However, studies on family burden and on the effect of family psychoeducational interventions on major depression are still very few in number and lack a rigorous methodology, clear outcome measures and adequate follow-ups. Despite this, the few available studies on the efficacy of psychoeducational family intervention in unipolar major depression have had promising results. A comprehensive management of unipolar major depression should include psychoeducational family intervention.

Family psychoeducation for major depression: randomised controlled trial

BACKGROUND

The value of family psychoeducation for schizophrenia has been well established, and indications for its use have recently expanded to include bipolar affective disorder. However, no study to date has adequately examined its use in depression.

AIMS

To examine family psychoeducation in the maintenance treatment of depression and to investigate the influence of the family's expressed emotion (EE) on its effectiveness.

METHOD

Of 103 patients diagnosed with major depression and their primary family members, 57 pairs provided written informed consent. The pairs were randomly allocated to the intervention (n = 25) or control (n = 32). One family in the intervention group and two in the control group withdrew their consent after randomisation. The intervention group underwent four psychoeducation sessions consisting of didactic lectures about depression and group problem-solving focusing on how to cope in high-EE situations. Patients did not attend these sessions. Patients in both the intervention and control groups received treatment as usual. The families' EE levels were evaluated through Five-Minute Speech Samples. The primary outcome was relapse.

RESULTS

Time to relapse was statistically significantly longer in the psychoeducation group than in the control group (Kaplan-Meier survival analysis, P = 0.002). The relapse rates up to the 9-month follow-up were 8% and 50% respectively (risk ratio 0.17, 95% CI 0.04-0.66; number needed to treat 2.4, 95% CI 1.6-4.9). In Cox proportional hazard analysis, baseline EE did not moderate the effectiveness of the intervention.

CONCLUSIONS

Family psychoeducation is effective in the prevention of relapse in adult patients with major depression.

Family and patient predictors of symptomatic status in schizophrenia

OBJECTIVE

To test an interactive hypothesis that, in schizophrenia, a combination of patients' and relatives' characteristics at 1-month postdischarge from hospital (Time 1 [T1]) better predicts the level of psychotic symptoms at follow-up (Time 2 [T2]), than do the characteristics of patients or relatives alone.

METHODS

Male patients (n = 38) with a diagnosis of schizophrenia, without substance abuse, and in contact with their families, were recruited at the time of hospital discharge. Patients' psychotic symptom levels were monitored every 2 weeks until follow-up, while family measures were administered at T1 and T2. The 4 predictor variables in the regression analysis were T1 symptom levels of the patient and 3 measures of family interaction (expressed emotion, family burden, and family functioning).

RESULTS

The model based on the family variable, family burden at T1, and the patient variable, patients' remitted levels of psychotic symptoms at T1, was found to significantly predict the level of psychotic symptoms at T2. These 2 T1 variables made independent and additive contributions to the level of psychotic symptoms at T2, predicting 19% of the variance. Neither expressed emotion nor family functioning at T1 added to the prediction.

CONCLUSION

This finding suggests a patient-family interactional component to symptomatic relapse in schizophrenia.

Impact of cognitive-psychoeducational interventions in bipolar patients and their relatives

BACKGROUND

In recent years, several controlled studies could show that psychoeducational interventions have been effective for relapse prevention in bipolar disorders. We therefore established a cognitive-psychoeducational group intervention with 14 sessions providing information about the illness, early warning signs, cognitive and behavioural strategies for stress management and social rhythm. Additionally we offered a group intervention for the patients' relatives. The objective of this study was to describe the outcome associated with our psychoeducational intervention in bipolar patients and their relatives.

METHODS

Sixty-two bipolar patients attended 14 sessions (à 90 min) of cognitive-psychoeducational group therapy. Patients' knowledge of bipolar disorder and their satisfaction with the treatment were assessed using self-developed questionnaires before and after the group intervention. Additionally, 49 relatives of bipolar patients received two psychoeducational workshops of 4 hours each. We assessed demographic variables, burden, high expressed emotion and depressive symptoms of the relatives before and after the two workshops and at 1-year follow-up.

RESULTS

Patients significantly improved their knowledge of bipolar disorder. They also have benefited from the discussions and the exchange of useful coping strategies. Burden and high expressed emotions showed no significant reductions at post-assessment, however they were significantly reduced at 1-year follow-up. Relatives also felt significantly better informed about the illness.

CONCLUSIONS

These findings show that psychoeducational interventions in bipolar patients and their relatives improve patients' and their relatives' knowledge of the illness and the burden of the disorder as well as high expressed emotions are reduced in relatives at 1-year follow-up.

Satisfaction with treatment among patients with depressive and bipolar disorders

BACKGROUND

Patients' satisfaction with care may be an important factor in relation to adherence to treatment and continued psychiatric care. Few studies have focused on satisfaction in patients with depressive and bipolar disorders.

METHOD

A comprehensive multidimensional questionnaire scale, the Verona Service Satisfaction Scale-Affective, was mailed to a large population of patients with depressive or bipolar disorders representative of outpatients treated at their first contact to hospital settings in Denmark.

RESULTS

Among the 1,005 recipients, 49.9% responded to the letter. Overall, patients were satisfied with the help provided, but satisfaction with the professionals' contact to relatives was low. Younger patients (age below 40 years) were consistently more dissatisfied with care especially with the efficacy of treatment, professionals' skills and behaviour and the information given. There was no difference in satisfaction between genders or between patients with depressive disorder and patients with bipolar disorder.

CONCLUSION

There is a need to strengthen outpatient treatment for patients discharged from a psychiatric hospital diagnosed of having affective disorders, focusing more on information and psychoeducation for patients and relatives.

Impact of a psychoeducational family intervention on caregivers of stabilized bipolar patients

BACKGROUND

Environmental stress has an important role in the course of bipolar disorder. Some findings have shown that family beliefs about the illness could predict family burden, and this burden could influence the outcome of bipolar disorder. To the best of our knowledge, there is scant information about the effects of family intervention on the caregiver's burden in bipolar disorder. The aim of this study was to assess the effects of psychoeducational family intervention on bipolar patients' caregivers, including the assessment of the caregiver's burden.

METHODS

45 medicated euthymic bipolar outpatients were randomized into an experimental and a control group. Relatives of patients from the experimental group received 12 psychoeducational, 90-min sessions about bipolar disorder and coping skills. The caregivers' knowledge of bipolar disorder, the relationship subscales of the Family Environment Scale, and the family burden subscales from an adapted version of the Social Behavior Assessment Schedule were assessed for both caregiver groups before and after the intervention.

RESULTS

Psycho-educated caregivers significantly improved their knowledge of bipolar disorder and reduced both the subjective burden and the caregiver's belief about the link between the objective burden and the patient. No significant differences were found in the objective burden nor in the family relationship subscales.

CONCLUSIONS

These preliminary results suggest that psychoeducational intervention on caregivers of bipolar patients may improve the caregiver's knowledge of the illness, reduce their distress or subjective burden and alter their beliefs about the link between the disruptions in their life and the patient's illness.

Validity of a five-minute speech sample for the measurement of expressed emotion in the families of Japanese patients with mood disorders

Both the Camberwell Family Interview (CFI) and the Five-Minute Speech Sample (FMSS) have been used to define expressed emotion (EE), but the validity of the FMSS relative to the CFI in mood disorders has not been evaluated. In our study, the FMSS and the CFI were performed on the same day in close family members of inpatients with mood disorders within 2 weeks after their admission. The ratings obtained from the CFI were then used to estimate the validity of the FMSS, which was defined by sensitivity and specificity on the basis of the overall evaluation of EE. Validity was also assessed by including borderline ratings of 'low EE' in the category of 'high EE.' Based on the overall evaluation, sensitivity and specificity were 66.7 and 96.8%, respectively. When borderline low EE was included in high EE, the sensitivity and specificity were 100 and 90.3%, respectively. The validity of definitions of EE by the FMSS relative to the CFI was high in mood disorders. Evaluation of EE by the FMSS, which is clinically applicable to patients with mood disorders, is feasible. The validity of this approach is enhanced when families defined as 'borderline low EE' are included in the high-EE category.

Family discord, parental depression, and psychopathology in offspring: ten-year follow-up

OBJECTIVE

To determine the independent effects of parental depression and family discord on psychopathology in offspring at high and low risk for major depression.

METHOD

One hundred eighty-two offspring of depressed or nondepressed parents were followed over 10 years. In direct interviews, parents' and offspring's psychopathology was evaluated by raters blind to parents' clinical status. Five dimensions of family discord-poor marital adjustment, parent-child discord, low family cohesion, affectionless control, and parental divorce-were assessed.

RESULTS

Offspring exposed to either parental depression or family discord had higher rates of psychopathology than their counterparts. High-risk offspring had few family discord measures associated with their psychopathology; in low-risk offspring, family discord was associated with all offspring diagnoses. Between the two risk factors, parental depression proved a more important predictor for offspring major depressive disorder (MDD) and anxiety disorder, whereas family discord was a more important predictor for substance use disorder.

CONCLUSIONS

Parental depression is a strong and consistent risk factor for offspring MDD and anxiety disorder. Without parental depression, offspring have less exposure to family discord and lower rates of psychopathology. In the presence of family discord, rates of MDD, anxiety disorder and substance use disorder increased. When offspring matured into young adulthood, effects of parental depression and family discord persisted.
