OBJECTIVE In a naturalistic follow-up of adult bipolar patients, the authors examined the contributions of demographic, phenomenological, and clinical variables, including antidepressant use, to prospectively observed mood episode frequency. METHOD For 1,742 bipolar I and II patients in the Systematic Treatment Enhancement Program for Bipolar Disorder (STEP-BD), episodes of mood disorders were evaluated for up to 1 year of treatment. RESULTS At entry, 32% of the patients met the DSM-IV criteria for rapid cycling in the prestudy year. Of the 1,742 patients, 551 (32%) did not complete 1 year of treatment. Among the 1,191 patients remaining, those with prior rapid cycling (N=356) were more likely to have further recurrences, although not necessarily more than four episodes per year. At the end of 12 months, only 5% (N=58) of the patients could be classified as rapid cyclers; 34% (N=409) had no further mood episodes, 34% (N=402) experienced one episode, and 27% (N=322) had two or three episodes. Patients who entered the study with earlier illness onset and greater severity were more likely to have one or more episodes in the prospective study year. Antidepressant use during follow-up was associated with more frequent mood episodes. CONCLUSIONS While DSM-IV rapid cycling was prospectively observed in only a small percentage of patients, the majority of these patients had continued recurrences at lower but clinically significant rates. This suggests that cycling is on a continuum and that prevention of recurrences may require early intervention and restricted use of antidepressants.

OBJECTIVE Depression and brief periods of (hypo)mania are linked to an increased risk of progression to bipolar I or II disorder (BD) in children of bipolar parents. This randomized trial examined the effects of a 4-month family-focused therapy (FFT) program on the 1-year course of mood symptoms in youth at high familial risk for BD, and explored its comparative benefits among youth in families with high versus low expressed emotion (EE). METHOD Participants were 40 youth (mean 12.3±2.8 years, range 9-17) with BD not otherwise specified, major depressive disorder, or cyclothymic disorder who had a first-degree relative with BD I or II and active mood symptoms (Young Mania Rating Scale [YMRS]>11 or Child Depression Rating Scale>29). Participants were randomly allocated to FFT-High Risk version (FFT-HR; 12 sessions of psychoeducation and training in communication and problem-solving skills) or an education control (EC; 1-2 family sessions). RESULTS Youth in FFT-HR had more rapid recovery from their initial mood symptoms (hazard ratio = 2.69, p = .047), more weeks in remission, and a more favorable trajectory of YMRS scores over 1 year than youth in EC. The magnitude of treatment effect was greater among youth in high-EE (versus low-EE) families. CONCLUSIONS FFT-HR may hasten and help sustain recovery from mood symptoms among youth at high risk for BD. Longer follow-up will be necessary to determine whether early family intervention has downstream effects that contribute to the delay or prevention of full manic episodes in vulnerable youth.

OBJECTIVES Previous studies have identified behavioral phenotypes that predispose genetically vulnerable youth to a later onset of bipolar I or II disorder, but few studies have examined whether early psychosocial intervention can reduce risk of syndromal conversion. In a one-year open trial, we tested a version of family-focused treatment adapted for youth at high risk for bipolar disorder (FFT-HR). METHODS A referred sample of 13 children (mean 13.4±2.69 years; 4 boys, 9 girls) who had a parent with bipolar I or II disorder participated at one of two outpatient specialty clinics. Youth met DSM-IV criteria for major depressive disorder (n=8), cyclothymic disorder (n=1), or bipolar disorder not otherwise specified (n=4), with active mood symptoms in the past month. Participants were offered FFT-HR (12 sessions in four months) with their parents, plus psychotropic medications as needed. Independent evaluators assessed depressive symptoms, hypomanic symptoms, and global functioning at baseline and then every four months for one year, with retrospective severity and impairment ratings made for each week of the follow-up interval. RESULTS Families were mostly adherent to the treatment protocol (85% retention), and therapists administered the FFT-HR manual with high levels of fidelity. Youth showed significant improvements in depression, hypomania, and psychosocial functioning scores on the Adolescent Longitudinal Interval Follow-up Evaluation. They also showed significant improvements in Young Mania Rating Scale and Childrens Depression Rating Scale scores. CONCLUSIONS FFT-HR is a promising intervention for youth at high risk for BD. Larger-scale randomized trials that follow youth into young adulthood will be necessary to determine whether early psychosocial intervention can reduce the probability of developing bipolar I or II disorder among genetically vulnerable youth.

OBJECTIVE Previous studies have found that family-focused treatment is an effective adjunct to pharmacotherapy in stabilizing symptoms in adult bipolar disorder. The authors examined whether pharmacotherapy and family-focused treatment for adolescents with bipolar disorder was more effective than pharmacotherapy and brief psychoeducation (enhanced care) in decreasing time to recovery from a mood episode, increasing time to recurrence, and reducing symptom severity over 2 years. METHOD A total of 145 adolescents (mean age, 15.6 years) with bipolar I or II disorder and a DSM-IV-TR manic, hypomanic, depressive, or mixed episode in the previous 3 months were randomly assigned, with family members, either to pharmacotherapy and family-focused treatment, consisting of psychoeducation (i.e., recognition and early intervention with prodromal symptoms), communication enhancement training, and problem-solving skills training, delivered in 21 sessions over 9 months; or to pharmacotherapy and three weekly sessions of enhanced care (family psychoeducation). Independent evaluators assessed participants at baseline, every 3 months during year 1, and every 6 months during year 2, using weekly ratings of mood. RESULTS Twenty-two participants (15.2%) withdrew shortly after randomization. Time to recovery or recurrence and proportion of weeks ill did not differ between the two treatment groups. Secondary analyses revealed that participants in family-focused treatment had less severe manic symptoms during year 2 than did those in enhanced care. CONCLUSIONS After an illness episode, intensive psychotherapy combined with best-practice pharmacotherapy does not appear to confer advantages over brief psychotherapy and pharmacotherapy in hastening recovery or delaying recurrence among adolescents with bipolar disorder.

Despite the considerable public health impact of bipolar disorder (BD), no psychosocial interventions have been systematically evaluated in its early prodromal stages. We describe the rationale, design and analytic methods for a 3‐site randomized trial of family‐focused treatment for youth at high risk (FFT‐HR) for BD.

BACKGROUND Adolescents with bipolar disorder (BD) report lower quality of life (QoL) than adolescents with other psychiatric disorders. This study compared the efficacy of family-focused therapy for adolescents (FFT-A) plus pharmacotherapy to brief psychoeducation (enhanced care, or EC) plus pharmacotherapy on self-rated QoL in adolescents with BD over 2 years. METHODS Participants were 141 adolescents (mean age: 15.6±1.4yr) with BD I or II who had a mood episode in the previous 3 months. Adolescents and parents were randomly assigned to (1) FFT-A, given in 21 sessions in 9 months of psychoeducation, communication enhancement training, and problem-solving skills training, or (2) EC, given in 3 family psychoeducation sessions. Study psychiatrists provided patient participants with protocol-based pharmacotherapy for the duration of the study. QoL was assessed with The KINDLRQuestionnaire (Ravens-Sieberer and Bullinger, 1998) during active treatment (baseline to 9 months) and during a post-treatment follow-up (9-24 months). RESULTS The two treatment groups did not differ in overall QoL scores over 24 months. However, adolescents in FFT-A had greater improvements in quality of family relationships and physical well-being than participants in EC. For quality of friendships, the trajectory during active treatment favored EC, whereas the trajectory during post-treatment favored FFT-A. LIMITATIONS We were unable to standardize medication use or adherence over time. Quality of life was based on self-report rather than on observable functioning. CONCLUSIONS A short course of family psychoeducation and skills training may enhance relational functioning and health in adolescents with BD. The effects of different psychosocial interventions on peer relationships deserves further study.
