Bipolar disorder: improving diagnosis and optimizing integrated care.

Bipolar disorder is a chronic, severe condition commonly causing substantial mortality and psychosocial morbidity. Challenges in recognition can delay the institution of appropriate management, whereas misdiagnosis may initiate pharmacologic interventions that adversely affect the condition's course. Pharmacotherapy remains the foundation of treatment. In addition to efficacy, tolerability is an important consideration in medication choice, particularly for long-term maintenance because of its impact on adherence. Mood stabilizers are the classic treatments for bipolar disorder. Newer agents such as atypical antipsychotics may offer efficacy and/or tolerability advantages compared with other medications. The role of antidepressants in bipolar disorder remains controversial. Growing evidence indicates that adjunctive psychosocial interventions improve long-term functioning; consequently, psychologists are becoming increasingly involved in the long-term care of patients with bipolar disorder. This review seeks to update psychologists and related healthcare professionals on recent advances and the current limitations in the diagnosis and treatment of bipolar disorder.

Is clinical depression distinct from subthreshold depressive symptoms? A review of the continuity issue in depression research.

Resolving whether subthreshold depressive symptoms exist on a continuum with unipolar clinical depression is important for progress on both theoretical and applied issues. To date, most studies have found that individuals with subthreshold depressive symptoms resemble cases of major depressive disorder along many important dimensions (e.g., in terms of patterns of functional impairment, psychiatric and physical comorbidity, familiality, sleeping EEG, and risk of future major depression). However, such manifest similarities do not rule out the possibility of a latent qualitative difference between subthreshold and diagnosable depression. Formal taxonomic analyses, intended to resolve the possibility of a latent qualitative distinction, have so far yielded contradictory findings. Several large-sample latent class analyses (LCA) have identified latent clinical and nonclinical classes of unipolar depression, but LCA is vulnerable to identification of spurious classes. Paul Meehl's taxometric methods provide a potentially conservative alternative way to identify latent classes. The one comprehensive taxometric analysis reported to date suggests that self-report depression symptoms occur along a latent continuum but exclusive reliance on self-report depression measures and incomplete information regarding sample base rates of depression makes it difficult to draw strong inferences from that report. We conclude that although most of the evidence at this time appears to favor both a manifest and latent continuum of unipolar depression symptomatology, several important issues remain unresolved. Complete resolution of the continuity question would be speeded by the application of both taxometric techniques and LCA to a single large sample with a known base rate of lifetime diagnosed depressives.

Why are empirically supported treatments for bulimia nervosa underutilized and what can we do about it?

Empirically supported therapies for bulimia nervosa, as well as for other disorders, are rarely utilized. Underutilization is frequently attributed to doubts among psychotherapists about the value of randomized controlled trials and professional resistance to the perceived constraints of manualized therapy. However, controversies about the usefulness of empirically supported therapies have been shaped by lack of access to adequate training and inexperience in delivering these treatments. A proposal for expanding training opportunities is presented along with discussion about how more intensive training for the practicing therapist would affect current controversies regarding the value and relevance of empirically supported therapies for bulimia nervosa and other disorders.

Psychotherapy for depression: current and future directions in research, theory, practice and public policy.

This article is based on a symposium held at the 1998 Annual Meeting of Society for Psychotherapy Research (Snow Bird, Utah). Recognized experts addressed current and future directions in psychotherapy for depression from the perspectives of process and outcome research, basic research, theoretical models, clinical practice and training, and public policy. The specific issues discussed at the symposium included the strengths and limitations of major forms of psychotherapy; the therapeutic factors common and unique to different approaches; the future viability of current theories of depression; the role of treatment manuals in clinical practice and training; the development of new interventions based on basic research; and the priorities that should guide federal funding.

Maintenance following a very-low-calorie diet.

The authors posed 2 questions in this randomized study of maintenance procedures in which participants were followed for 15 months after completion of a very-low-calorie diet: Would stimulus narrowing during the reintroduction of solid food, achieved by the use of prepackaged foods, improve weight losses and the maintenance of those losses as compared with the use of regular food? Would reintroduction of foods dependent on progress in losing or maintaining weight be superior to reintroduction on a time-dependent basis? Neither the stimulus narrowing condition nor the reintroduction procedure enhanced either maximum weight loss or maintenance of those losses. The stimulus narrowing condition appeared to be poorly tolerated; compliance and attendance were poorer in this condition than in the regular food condition.

Severity of child maltreatment, pain complaints and medical utilization among women.

High medical utilization in adults has been linked to both reported history of childhood abuse and mental health problems. However, few studies have explored relationships between abuse severity and psychological distress to identify subgroups with unique utilization patterns and medical complaints. This study compared two groups of psychologically distressed, high utilizers. One group (DS) was comprised of those with psychological distress, who reported a history of child sexual abuse (CSA); the other group (DSP) consisted of those with psychological distress, who reported CSA plus a history of childhood physical abuse. The groups were compared on severity of sexual and nonsexual child maltreatment, medical complaints and medical utilization. From a convenience sample of 206 females age 20-63, recruited while waiting for a physician appointment in a primary care clinic, we compared 25 DSPs to 33 DSs. Compared with DSs, DSPs reported significantly more severe: (1) sexual abuse including completed intercourse; (2) emotional abuse; (3) emotional neglect; and (4) psychological distress. DSPs also showed a nonsignificant trend towards more severe physical neglect. In addition to being significantly higher on emergency room visits, DSPs were marginally higher than DSs on nonpsychiatric outpatient visits. DSPs had significantly more frequent chronic and acute pain complaints at emergency room (ER) visits. Headaches were the most frequently coded diagnosis at ER visits in this sample. DSPs accounted for 89% of these ER visits attributable to headaches. The interaction of psychological distress and reported severity of child maltreatment reveals subgroups with unique utilization patterns and medical complaints. Physicians should screen patients for child maltreatment severity and psychological distress and should be involved in mental health referral where necessary.

Childhood sexual abuse, psychological distress, and medical use among women.

OBJECTIVE: This study examined the relationships between reported history of childhood sexual abuse (CSA), psychological distress, and medical utilization among women in a health maintenance organization (HMO) setting. METHODS: Participants were 206 women aged 20 to 63 years who were recruited from an HMO primary care clinic waiting area. Participants were classified, using screening questionnaires and the revised Symptom Checklist 90, as 1) CSA-distressed, 2) distressed only, 3) CSA only, or 4) control participants. Medical utilization rates were generated from the computerized database of the HMO for 1) nonpsychiatric outpatient, 2) psychiatric outpatient, 3) emergency room (ER), and 4) inpatient admissions. RESULTS: CSA-distressed and distressed only groups both used significantly more nonpsychiatric outpatient visits than CSA only and control participants but were not different from one another. CSA only and control participants did not differ on nonpsychiatric outpatient utilization. CSA-distressed participants used significantly more ER visits and were more likely to visit the ER for pain-related complaints than other participants. Among CSA-distressed participants, those who met criteria for physical abuse had significantly more ER visits than those who did not. There were no differences among the four groups in inpatient utilization rates. CONCLUSIONS: Psychological distress is associated with higher outpatient medical utilization, independent of CSA history. History of CSA with concomitant psychological distress is associated with significantly higher ER visits, particularly for those with a history of physical abuse. History of CSA without distress is not associated with elevated rates of medical utilization. Screening for psychological distress, CSA, and physical abuse may help to identify distinct subgroups with unique utilization patterns.
