Patients' expectancies, the alliance in pharmacotherapy, and treatment outcomes in bipolar disorder.

Bipolar disorder is characterized by a chronic and fluctuating course of illness. Although nonadherence to pharmacotherapy is a frequent problem in the disorder, few studies have systematically explored psychosocial factors related to treatment discontinuation. Previous research with depressed patients receiving psychotherapy has suggested that expectancies for improvement are related to treatment outcomes and that the therapeutic alliance may partially mediate this relationship. The current study found evidence for a similar relationship between patients' initial expectancies for improvement, patient and doctor-rated alliance, and long-term outcomes in bipolar patients treated with pharmacotherapy for up to 28 months following an acute episode. The results highlight the need for the assessment of expectancies and alliance in bipolar treatment and suggest possible targets for psychosocial interventions.

Family functioning and mood disorders: a comparison between patients with major depressive disorder and bipolar I disorder.

Within a sample of patients with major depressive disorder (MDD; n = 121) and bipolar affective disorder (BPAD; n = 69), the authors examined (a) diagnostic differences in family functioning at acute episode, (b) diagnostic differences in family functioning at episode recovery, (c) within-group changes in family functioning from acute episode to recovery, and (d) whether within-group changes from acute episode to recovery varied by diagnosis. Using a multidimensional model, the authors evaluated interviewer, patient, and family ratings. Overall, patients with MDD and BPAD evidenced similar levels of family impairment at acute episode and recovery. Generally, patients in both groups experienced improvement in family functioning over time, yet mean scores at recovery continued to range from fair to poor. Although certain specific differences emerged, diagnostic groups appeared to be more similar than different in level and pattern of family functioning.

Family functioning in bipolar I disorder.

In a sample of 62 patients with Bipolar I disorder, the authors used a repeated measures longitudinal design to examine whether global family functioning was associated with the presence of a concurrent bipolar episode as well as whether global family functioning was associated with the presence of manic and depressive episodes in the following 3 months. Participants were recruited for a randomized clinical trial examining the efficacy of family treatments combined with pharmacotherapy for bipolar disorder. Global family functioning was repeatedly measured with both clinician-rated and patient-rated assessment instruments over the 28-month study period. Results indicated that mood episodes were associated with concurrent global family functioning within individuals, but global family functioning was not associated with episode status in the subsequent 3 months. The repeated measures nature of these results suggests that global family functioning and bipolar episodes may fluctuate in concert with each other but that global family functioning is not associated with subsequent change in episode status.

Clinical characteristics of perinatal psychiatric patients: a chart review study.

Although postpartum depression and other perinatal disorders have been the subject of increased research attention, important questions remain regarding women who actively seek psychiatric treatment during pregnancy and the postpartum period. In this study, we examined clinical records of 500 perinatal psychiatric patients who received treatment in a psychiatric day hospital (N = 398) or outpatient behavioral health clinic (N = 102). Patients' presenting diagnoses, psychiatric history, treatment course, and depressive symptoms were recorded. The majority of women had major depression as their primary diagnosis, with an average Edinburgh Postnatal Depression Scale score of over 20. Many depressed patients were diagnosed with comorbid anxiety and substance abuse disorders. Although most women were willing to take psychotropic medications, a sizable minority were not, particularly those who were breast-feeding. For more than a third of the sample, the treatment sought while pregnant or postpartum represented their first contact with the mental health system. Treatment implications are discussed.

The family check-up: a pilot study of a brief intervention to improve family functioning in adults.

Many barriers exist for families seeking appropriate treatment for family problems. In an effort to minimize some of these barriers, we developed the Family Check-Up, a brief two-session family intervention. The Family Check-Up is based on the Drinker's Check-Up and consists of assessment, feedback, discussion, and goal setting. The purpose of the intervention is to help families identify and become motivated to make needed changes in any aspect of their family functioning. We conducted an open pilot trial of the Family Check-Up with 32 families. Our data suggest that the Family Check-Up (1) is sought out by the target audience, namely those with family problems; (2) is sought out by people with elevated depression symptoms or a history of treatment for depression or anxiety; (3) is feasible to conduct; (4) is acceptable to families; and (5) may be associated with changes in family functioning and depression symptoms over time. These results suggest that further research, particularly a randomized clinical trial, is warranted.

A preventive intervention for pregnant women on public assistance at risk for postpartum depression.

OBJECTIVE: Promising results were obtained in an earlier pilot study of a preventive intervention based on the principles of interpersonal psychotherapy to reduce the risk of postpartum major depressive disorder. In this study, the authors examined whether the intervention would reduce the risk of postpartum major depressive disorder in a larger sample of pregnant women. METHOD: Ninety-nine pregnant women on public assistance who were assessed to be at risk for postpartum depression were randomly assigned to receive standard antenatal care plus the intervention or standard antenatal care only. Diagnostic interviews were administered 3 months after delivery to assess for major depressive disorder. RESULTS: Within 3 months after delivery, eight (20%) of the women in the standard antenatal care condition had developed postpartum major depressive disorder, compared with two (4%) in the intervention condition. CONCLUSIONS: This study provides further evidence for the efficacy of a brief intervention to reduce the occurrence of major depressive disorder among financially disadvantaged women during a postpartum period of 3 months.

Anxiety disorder comobidity in Bipolar I Disorder: relationship to depression severity and treatment outcome.

The present study investigated the greater symptom severity and poorer treatment response found in patients with bipolar illness and anxiety comorbidity, and examined depression as a potential mediator of this relationship. The sample consisted of 92 patients in an acute episode of Bipolar I Disorder with a current or past history of an anxiety disorder. Diagnoses were based on structured clinical interview, and participants were assessed at pre-treatment and then randomly assigned to pharmacotherapy alone or pharmacotherapy plus family intervention. Patients were assessed on a monthly basis by blind assessors over 28 months. Compared to patients without anxiety comorbidity, individuals with bipolar disorder and an anxiety disorder possessed greater current symptom severity, even after controlling for depression severity. Logistic regression analysis identified that being female and having higher current depression but not manic severity predicted comorbid anxiety. Comorbid anxiety was associated with poorer treatment response in the sample regardless of treatment type, particularly in subsequent depressive symptoms. Multiple regression analyses indicated that current depression but not manic severity partially mediated the relationship between comorbid anxiety and treatment outcome. Results from the current study investigating comorbid anxiety disorders are consistent with past research limited to anxiety symptoms. Depression only partially accounted for the link between comorbid anxiety and greater symptom severity and poorer treatment response, and examination of other factors is warranted. Because of the clinical relevance of comorbid anxiety in severe affective disorders, treatments designed to specifically address both concerns are needed.

Unlinking negative cognition and symptoms of depression: evidence of a specific treatment effect for cognitive therapy.

In this study, the authors examined whether cognitive therapy alters the association between negative cognition and symptoms of depression. Participants were recruited during psychiatric hospitalization for depression. Following discharge, they were randomly assigned to 6 months of outpatient treatment. Treatment consisted of pharmacotherapy either alone or in combination with cognitive therapy and/or family therapy. Following this 6-month treatment period, negative cognition and symptoms of depression were assessed monthly for 1 year. Hierarchical linear modeling indicated that the association between negative cognition and depression during follow-up was weaker for patients randomized to cognitive therapy than for patients who did not receive cognitive therapy. Cognitive therapy appeared to unlink negative cognition and symptoms of depression to a greater extent than other forms of treatment.

Developing a culturally appropriate depression prevention program: the family coping skills program.

Depression is a disorder that can have particularly deleterious effects on individuals from racial/ethnic minority and low-income backgrounds. Culturally appropriate prevention programs offer a way to provide accessible and effective mental health services to these underserved populations. The authors introduce the Family Coping Skills Program (FCSP), a novel depression prevention program developed specifically for low-income Latina mothers. The authors present the theoretical underpinnings of the FCSP and describe their efforts to make the program culturally appropriate and to enhance recruitment and retention of participants. Initial outcome data from an uncontrolled trial were promising and support continued development and evaluation of the FCSP and other similar programs.

Reductions in HIV risk behaviors among depressed drug injectors.

OBJECTIVE: To determine if, by reducing depressive symptoms, combined psychotherapy and pharmacotherapy reduces HIV drug risk behavior compared to an assessment-only condition for active drug injectors over 9 months. DESIGN: Randomized controlled trial. SETTING: Outpatient academic research office. PATIENTS: Active injection drug users with a DSM-IV diagnosis of major depression, dysthymia, substance-induced mood disorder with depressive features persisting for at least 3 months, or major depression plus dysthymia. In addition, participants had a Hamilton Rating Scale for Depression (MHRSD) score > 13. INTERVENTION: Psychotherapy (8 sessions of cognitive behavioral therapy) plus antidepressant pharmacotherapy over 3 months. MAIN OUTCOME MEASURES: HIV Risk Assessment Battery (RAB) drug scale scores measured at three, six and nine months, and depression remission (MHRSD score < or = 8). RESULTS: Participants (n= 109) were 64% male, 82% Caucasian, with a mean baseline MHRSD score of 20.7. Depression subtypes included major depression only (63%), substance-induced depression (17%), and double-depression (17%). Overall, study retention at nine months was 89%. Reported HIV drug risk scores decreased sharply over the first 3 months and continued to decline throughout the follow-up period. Between group differences were not significant in the intention-to-treat analysis. However, highly adherent participants had significantly lower HIV drug risk scores at 3 months (p<05), but not 6 and 9 months. Depression remission was significantly associated with lower HIV drug risk scores at follow-ups. CONCLUSIONS: Combined psychotherapy and pharmacotherapy did not produce a significant reduction in HIV drug risk beyond that seen in an assessment-only control group. The greatest declines in HIV drug risk were found in participants with high protocol adherence and those with depression remission.

Differential response to combined treatment in patients with psychotic versus nonpsychotic major depression.

Research has demonstrated that depressed patients with psychotic features show poorer outcomes when treated with pharmacotherapy alone compared with those without psychotic features. However, research has not investigated whether this differential response also applies to combined treatment that includes pharmacotherapy and psychotherapy. In the current study, data were pooled from two clinical trials in which patients diagnosed with major depressive disorder with or without psychotic features were treated with combined treatment. Although similar in severity at pretreatment, results indicated that patients with psychotic depression showed a poorer response in terms of depression severity at postoutpatient treatment and at 6-month follow-up compared with those with nonpsychotic depression. Following treatment, patients with psychotic depression were over four times as likely to exhibit high levels of depression and suicidal ideation. Current state-of-the-art combined treatments have poorer efficacy in depressed patients with psychotic symptoms, and adapted treatment approaches are needed.

Treatment matching in the posthospital care of depressed patients.

OBJECTIVE: This study assessed the efficacy of 1) matching patients to treatments and 2) adding additional family therapy or cognitive therapy in a group of recently discharged patients with major depression. METHOD: Patients with major depression were recruited during a psychiatric hospitalization. After discharge, they were randomly assigned to one of four treatment conditions that were either "matched" or "mismatched" to their pattern of cognitive distortion and family impairment. The four treatment conditions were 1) pharmacotherapy alone; 2) combined pharmacotherapy and cognitive therapy; 3) combined pharmacotherapy and family therapy; and 4) combined pharmacotherapy, cognitive therapy, and family therapy. Randomly assigned treatment continued for 24 weeks on an outpatient basis. RESULTS: Among patients with at least moderate depressive symptoms at hospital discharge, low rates of remission (16%) and improvement (29%) were obtained. Matched treatment led to a significantly greater proportion of patients who improved and greater reductions over time in interviewer-rated depressive symptoms than mismatched treatment. However, matched treatment did not produce greater change in self-reported depression or interviewer-rated suicidal ideation. Treatment that included a family therapy component also led to a greater proportion of patients who improved and to significant reductions in interviewer-rated depression and suicidal ideation than treatment without family therapy. CONCLUSIONS: These results suggest that 1) current treatments are not very efficacious in the aftercare of hospitalized depressed patients, 2) treatment matching moderately improves outcome for patients who are symptomatic at hospital discharge, and 3) inclusion of family therapy improves the outcome of posthospital care for depressed patients.

Does adjunctive family therapy enhance recovery from bipolar I mood episodes?

BACKGROUND: Family therapy is sometimes used as adjunctive treatment to pharmacotherapy to help patients recover from mood episodes of bipolar I disorder. However, the efficacy of this practice is not known. METHODS: Ninety-two patients meeting criteria for a current bipolar I mood episode were randomly assigned to family therapy plus pharmacotherapy, multifamily psychoeducational group therapy plus pharmacotherapy, or pharmacotherapy alone. Time to recovery was analyzed with survival analysis. RESULTS: The proportion of subjects within each treatment group who recovered did not significantly differ, nor did time to recovery. LIMITATIONS: The analyses did not include other outcomes such as psychosocial functioning, prophylaxis against recurrences of mood episodes, or compliance with pharmacotherapy. CONCLUSIONS: Neither adjunctive family therapy nor adjunctive multifamily psychoeducational group therapy significantly improves the rate of recovery from mood episodes of bipolar I disorder, compared to treatment with pharmacotherapy alone.

Pharmacotherapy plus psychotherapy for treatment of depression in active injection drug users.

CONTEXT: Depressive disorders are common among opiate abusers and are associated with detrimental behavioral effects. However, there is little precedent for offering active drug users complex treatments for depression. OBJECTIVE: To determine whether combined psychotherapy and pharmacotherapy treatment reduces reported depressive symptoms compared with an assessment-only condition among out-of-treatment drug injectors. DESIGN: Randomized controlled trial. SETTING: Research office located at an academic medical center. PATIENTS: Active injection drug users with a DSM-IV diagnosis of major depression, dysthymia, substance-induced mood disorder with symptoms persisting for at least 3 months, or major depression plus dysthymia, and a Modified Hamilton Rating Scale for Depression (HAM-D) score greater than 13. INTERVENTION: Combined psychotherapy (8 sessions of cognitive behavior therapy) plus pharmacotherapy (citalopram). MAIN OUTCOME MEASURES: Modified HAM-D scale scores at the end of 3 months of combined treatment. RESULTS: The 109 study subjects were 64% male and had a mean age of 36.7 years and a mean baseline HAM-D score of 20.7. Depression subtypes included major depression only (63%), substance-induced depression (17%), and major depression plus dysthymia (17%). In the intent-to-treat analysis, participants in treatment averaged 2.11 HAM-D points greater improvement than control subjects (P=.08), and 26.1% of combined treatment patients (n=53) compared with 12.5% of control patients (n=56) were in remission (P=.047). Nearly 40% of fully adherent subjects (receiving >75% of either psychotherapy or pharmacotherapy) were in remission at follow-up (odds ratio, 3.6; P=.04). CONCLUSIONS: Combined treatment for depression is significantly superior to a control condition (assessment only) in proportion of patients in remission, but not in HAM-D improvement among drug injectors. Full adherence to treatment is associated with the largest treatment effects. Our findings demonstrate that active drug users with dual diagnoses are able to participate in conventional treatment.

Adherence to treatment of depression in active injection drug users: the minerva study.

The impact of depression on drug users is extensive, serving as a trigger for high-risk injection practices and continued drug use. Yet the ability to retain active drug users in mental health treatment has never been tested clinically. We recruited injection drug users (IDU) for a randomized study of combined psychotherapy and pharmacotherapy for the treatment of depression. Among the 53 SCID-diagnosed depressed subjects assigned to the combined treatment group, 43.4% were "fully adherent" to treatment (75% or greater attendance at cognitive-behavioral therapy (CBT) sessions or 75% or greater adherence to the pharmacotherapy regimen). The correlation of CBT attendance and pharmacotherapy use was high (r(s) =.74). Persons with double depression (major depression plus dysthymia) were most likely to be fully adherent (p =.01); frequency of heroin use was inversely associated with adherence. Developing public health treatment interventions to engage out-of-treatment, dually-diagnosed IDUs is possible.

Cognitive vulnerability to depression: a taxometric analysis.

Although there is increasing support for the hypothesis that negative cognitive styles contribute vulnerability to depression, it remains unclear how best to conceptualize the heterogeneity in cognitive vulnerability to depression. Specifically, does this heterogeneity reflect quantitative or qualitative differences among individuals? The goal of this study was to address this question by examining whether the underlying structure of cognitive vulnerability to depression is best conceptualized as dimensional or categorical. Taxometric analyses provided consistent support for the dimensional nature of negative cognitive styles. It appears, therefore, that cognitive vulnerability to depression is best conceptualized as a dimensional construct, present to a greater or lesser extent in all individuals. Despite this, the strength of the relationship between negative cognitive styles and depressive symptoms does appear to vary as a function of where along the cognitive style continuum one falls.

Cognitive-behavioral analysis system of psychotherapy as a maintenance treatment for chronic depression.

Although the efficacy of maintenance pharmacotherapy for the prevention of recurrence in major depressive disorder (MDD) is well documented, few studies have tested the efficacy of psychotherapy as a maintenance treatment. The authors examined the efficacy of the cognitive-behavioral analysis system of psychotherapy (CBASP) as a maintenance treatment for chronic forms of MDD. Eighty-two patients who had responded to acute and continuation phase CBASP were randomized to monthly CBASP or assessment only for 1 year. Significantly fewer patients in the CBASP than assessment only condition experienced a recurrence. The 2 conditions also differed significantly on change in depressive symptoms over time. These findings support the use of CBASP as a maintenance treatment for chronic forms of MDD.
