Psychotherapy and depressive symptom trajectories among VA patients: Comparing dose-effect and good-enough level models

Objective: Psychotherapy for depression is effective for many veterans, but the relationship between number of treatment sessions and symptom outcomes is not well established. The Dose-Effect model predicts that greater psychotherapeutic dose (total sessions) yields greater symptom improvement with each additional session resulting in smaller session-to-session improvement. In contrast, the Good-Enough Level (GEL) model predicts that rate of symptom improvement varies by total psychotherapeutic dose with faster improvement associated with earlier termination. This study compared the dose-effect and GEL model among veterans receiving psychotherapy for depression within the Veterans Health Administration. Method: The sample included 13,647 veterans with ≥2 sessions of psychotherapy for depression with associated Patient Health Questionnaire-9 (PHQ-9) scores in primary care (n = 7,502) and specialty mental health clinics (n = 6,145) between October 2014 and September 2018. Multilevel longitudinal modeling was used to compare the Dose-Effect and GEL models within each clinic type. Results: The GEL model demonstrated greater fit for both clinic types relative to dose-effect models. In both treatment settings, veterans with fewer sessions improved faster than those with more sessions. In primary care clinics, veterans who received 4-8 total sessions achieved similar levels of symptom response. In specialty mental health clinics, increased psychotherapeutic dose was associated with greater treatment response up to 16 sessions. Veterans receiving 20 sessions demonstrated minimal treatment response. Conclusions: These findings support the GEL model and suggest a flexible approach to determining length of psychotherapy for depression may be useful for optimizing treatment response and allocation of clinical resources.

Prevalence, Comorbidity, and Prognosis of Mental Health Among US Veterans

OBJECTIVES

We evaluated the association of mental illnesses with clinical outcomes among US veterans and evaluated the effects of Primary Care-Mental Health Integration (PCMHI).

METHODS

A total of 4 461 208 veterans were seen in the Veterans Health Administration's patient-centered medical homes called Patient Aligned Care Teams (PACT) in 2010 and 2011, of whom 1 147 022 had at least 1 diagnosis of depression, posttraumatic stress disorder (PTSD), substance use disorder (SUD), anxiety disorder, or serious mental illness (SMI; i.e., schizophrenia or bipolar disorder). We estimated 1-year risk of emergency department (ED) visits, hospitalizations, and mortality by mental illness category and by PCMHI involvement.

RESULTS

A quarter of all PACT patients reported 1 or more mental illnesses. Depression, SMI, and SUD were associated with increased risk of hospitalization or death. PTSD was associated with lower odds of ED visits and mortality. Having 1 or more contact with PCMHI was associated with better outcomes.

CONCLUSIONS

Mental illnesses are associated with poor outcomes, but integrating mental health treatment in primary care may be associated with lower risk of those outcomes.

Patient preference as a moderator of outcome for chronic forms of major depressive disorder treated with nefazodone, cognitive behavioral analysis system of psychotherapy, or their combination

BACKGROUND

Little is known about moderators of response to psychotherapy, medication, and combined treatment for chronic forms of major depressive disorder (MDD). We hypothesized that patient preference at baseline would interact with treatment group to differentially affect treatment outcome.

METHOD

We report outcomes for 429 patients who participated in a randomized multicenter trial of nefazodone, Cognitive Behavioral Analysis System of Psychotherapy (CBASP), or combination therapy for chronic forms of MDD (DSM-IV criteria) and who indicated their preference for type of treatment at study entry. The primary outcome measures were total scores on the 24-item Hamilton Rating Scale for Depression (HAM-D-24) and categorical definitions of remission or partial response. The patients were recruited between June 1996 and December 1997.

RESULTS

There was an interactive effect of preference and treatment group on outcome. The treatment effect varied as a function of preference, and was particularly apparent for patients who initially expressed preference for one of the monotherapies. Patients who preferred medication had a higher remission rate (45.5%) and lower mean HAM-D-24 score (11.6) at study exit if they received medication than if they received psychotherapy (remission rate, 22.2%; mean HAM-D-24 score, 21.0). Patients who preferred psychotherapy had a higher remission rate (50.0%) and lower mean HAM-D-24 score (12.1) if they received psychotherapy than if they received medication (remission rate 7.7%, mean HAM-D-24 score 18.3). Nevertheless, treatment preference was not associated with risk of dropout from the study.

CONCLUSIONS

These results suggest that patient preference is a potent moderator of treatment response for patients with chronic forms of MDD; however, relatively low proportions of the patient sample preferred one of the monotherapies, participants were not blinded to treatment assignment, and there was no placebo group.

In the mind's eye: provider and patient attitudes on functional brain imaging

Success in functional neuroimaging has brought the promise of quantitative data in the form of brain images to the diagnosis of disorders of the central nervous system for which only qualitative clinical criteria have previously existed. Even though the translation of research to clinical neuroimaging for conditions such as major depression may not be available yet, rapid innovation along this trajectory of discovery to implementation compels exploration of how such information will eventually affect providers and patients. Clinical neuroethics is devoted to elucidating ethical challenges prior to and during the transfer of new research capabilities to the bedside. Through a model of proactive ethics, clinical neuroethics promotes the development of responsible social and public policies in response to new diagnostic and prognostic capabilities for the benefit of patients and their families, and for providers within the health care systems in which they practice. To examine views about the potential interaction of clinical neuroimaging and depression, we surveyed both mental health providers and outpatients and inpatients diagnosed with major depressive disorder. From responses of 52 providers and 72 patients, we found high receptivity to brain scans for treatment tailoring and choice, for improving understanding of and coping with disease, and for mitigating the effects of stigma and self-blame. Our results suggest that, once ready, roll out of the fully validated technology has significant potential to reduce social burden associated with highly stigmatized illnesses like depression.

The abuse-related beliefs questionnaire for survivors of childhood sexual abuse

OBJECTIVE

To evaluate the psychometric properties of a new measure, the Abuse-Related Beliefs Questionnaire (ARBQ), designed to assess abuse-related beliefs among adult survivors of childhood sexual abuse (CSA). Study 1 examined the structure of the scale, and Study 2 evaluated its reliability and validity.

METHOD

One hundred and seventy female CSA survivors recruited into a group psychotherapy intervention study were administered the ARBQ in Study 1. A subsample of 45 women completed the ARBQ again 12 months later. In Study 2, 70 women from a health maintenance organization who identified themselves as survivors of CSA completed the ARBQ along with the Trauma Symptom Checklist-40 (TSC-40) and the Symptom Checklist 90R (SCL-90-R).

RESULTS

Three reliable ARBQ subscales emerged in Study 1: Guilt, Shame, and Resilience. Twelve-month test-retest reliability was high (r=.60-.64). The internal consistency of the subscales was further supported in Study 2, and validity was demonstrated by moderate to high correlations with the distress measures.

CONCLUSIONS

The results indicate that the ARBQ has good psychometric characteristics, supporting the feasibility of its use in measuring abuse-related beliefs in research on survivors of CSA. A next step for validation of the ARBQ would be to evaluate its sensitivity in measuring changes in studies of interventions for treating CSA survivors.

The efficacy of divalproex sodium in the treatment of agitation associated with major depression

BACKGROUND

Agitation is both a feature of major depression and a common side effect of antidepressant treatment. Depressive agitation correlates with overall severity of illness and suicide risk, whereas treatment-emergent agitation may contribute to early discontinuation of pharmacotherapy. Thus, agitation merits investigation as a treatment target in clinical depression.

METHODS

In this study, adults with major depression were evaluated for change in agitation and other mood symptoms during adjunctive treatment with divalproex sodium. Twelve patients on antidepressants, who met Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition criteria for major depression, were given low doses of divalproex sodium and evaluated repeatedly for symptoms of depression, anxiety, and agitation. Agitation severity was evaluated using the Overt Agitation Severity Scale and the Stanford Scale for Agitation Symptoms. Mood symptoms were assessed with the Hamilton Anxiety and the Hamilton Depression Rating Scales.

RESULTS

Nine of 12 patients completed 4 weeks of treatment. All agitation scores decreased sharply, whereas depression (Hamilton Depression Rating Scale) and anxiety (Hamilton Anxiety Rating Scale) symptoms decreased only modestly. Decreased agitation was not merely a function of decreases on the Hamilton Depression or Hamilton Anxiety Rating Scales. Relatively low doses of divalproex sodium appear to be useful in the treatment of agitation associated with major depression.

CONCLUSIONS

The observation that decreases in agitation were not simply an artifact of overall change in depressive or anxiety symptoms is in keeping with the previous clinical impression that divalproex sodium has a specific effect on depressive agitation. Controlled clinical trials are needed to fully evaluate the utility and symptom specificity of divalproex sodium in depression.

Assessing insomnia severity in depression: comparison of depression rating scales and sleep diaries

Depression and sleep researchers typically assess insomnia severity differently. Whereas depression researchers usually assess insomnia with items on depression symptom inventories, sleep researchers usually assess the subjective experience of insomnia with sleep diaries. The present manuscript utilizes baseline data from 397 participants in a large multi-site chronic depression study to assess agreement between these two methodologies. The results indicate that the early, middle, and late insomnia items of the Hamilton Rating Scale for Depression (HRSD(24)) and the Inventory of Depression Symptoms - Self Report (IDS-SR(30)) are highly correlated with the weekly mean values of time to sleep onset, time awake after sleep onset, and time awake prior to the planned wake-up obtained from prospective sleep diaries. Results also reveal significant correspondence between the weekly-mean of daily sleep efficiency, an accepted measure of sleep continuity (the ratio between reported time asleep and time in bed), and the insomnia scale scores of the HRSD(24) and the IDS-SR(30) (the mean score on the three insomnia items of each depression measure). Unit increments in HRSD(24) scores for early, middle and late insomnia were associated with significant increases in unwanted minutes awake for corresponding periods on sleep diaries. Similar relationships were found for early insomnia on the IDS-SR(30) but not for middle and late insomnia. Overall, with few exceptions, findings revealed substantial agreement between the HRSD(24), IDS-SR(30) and prospective sleep diary data. The study supports the validity of the sleep items and sleep subscales of the HRSD(24) and the IDS-SR(30) as global measures of insomnia severity in depression. Conventional sleep assessment procedures can complement depression scales by providing additional information about specific aspects of sleep in depression.

Self-reported depressive symptom measures: sensitivity to detecting change in a randomized, controlled trial of chronically depressed, nonpsychotic outpatients

This study evaluated and compared the performance of three self-report measures: (1) 30-item Inventory of Depressive Symptomatology-Self-Report (IDS-SR30); (2) 16-item Quick Inventory of Depressive Symptomatology-Self-Report (QIDS-SR16); and (3) Patient Global Impression-Improvement (PGI-I) in assessing clinical outcomes in depressed patients during a 12-week, acute phase, randomized, controlled trial comparing nefazodone, cognitive-behavioral analysis system of psychotherapy (CBASP), and the combination in the treatment of chronic depression. The IDS-SR30, QIDS-SR16, PGI-I, and the 24-item Hamilton Depression Rating Scale (HDRS24) ratings were collected at baseline and at weeks 1-4, 6, 8, 10, and 12. Response was defined a priori as a > or =50% reduction in baseline total score for the IDS-SR30 or for the QIDS-SR16 or as a PGI-I score of 1 or 2 at exit. Overall response rates (LOCF) to nefazodone were 41% (IDS-SR30), 45% (QIDS-SR16), 53% (PCI-I), and 47% (HDRS17). For CBASP, response rates were 41% (IDS-SR30), 45% (QIDS-SR16), 48% (PGI-I), and 46% (HDRS17). For the combination, response rates were 68% (IDS-SR30 and QIDS-SR16), 73% (PGI-I), and 76% (HDRS17). Similarly, remission rates were comparable for nefazodone (IDS-SR30=32%, QIDS-SR16=28%, PGI-I=22%, HDRS17=30%), for CBASP (IDS-SR30=32%, QIDS-SR16=30%, PGI-I=21%, HDRS17=32%), and for the combination (IDS-SR30=52%, QIDS-SR16=50%, PGI-I=25%, HDRS17=49%). Both the IDS-SR30 and QIDS-SR16 closely mirrored and confirmed findings based on the HDRS24. These findings raise the possibility that these two self-reports could provide cost- and time-efficient substitutes for clinician ratings in treatment trials of outpatients with nonpsychotic MDD without cognitive impairment. Global patient ratings such as the PGI-I, as opposed to specific item-based ratings, provide less valid findings.

Childhood Sexual and Physical Abuse and the 1-Year Prevalence of Medical Problems in the National Comorbidity Survey

In a population sample (N=5,877; ages 15 to 54), the authors found childhood sexual and physical abuse to be associated with the 1-year prevalence of serious health problems for both men and women. The authors also found that participants' psychiatric disorders partially mediated the effects of physical and sexual abuse on adult health. However, childhood abuse continued to independently influence health status after the authors controlled for psychiatric disorders. Contrary to expectations, individuals who experienced a combination of sexual and physical abuse did not have a higher frequency of health problems than those who experienced either type of abuse alone. Implications for these findings are discussed, including possible mechanisms that may account for the association between childhood abuse and adult health problems.

Randomized, placebo-controlled trial of nefazodone maintenance treatment in preventing recurrence in chronic depression

BACKGROUND

Maintenance treatment to prevent recurrences is recommended for chronic forms of major depressive disorder (MDD), but few studies have examined maintenance efficacy of antidepressants with chronic MDD. This randomized, placebo-controlled study of the efficacy and safety of nefazodone in preventing recurrence was conducted for patients with chronic MDD.

METHODS

A total of 165 outpatients with chronic, nonpsychotic MDD, MDD plus dysthymic disorder ("double-depression"), or recurrent MDD with incomplete inter-episode recovery, who achieved and maintained a clinical response during acute and continuation treatment with either nefazodone alone or nefazodone combined with psychotherapy, were randomized to 52 weeks of double-blind nefazodone (maximum dose 600 mg/day) or placebo. The occurrence of major depressive episodes during maintenance treatment was assessed with the 24-item Hamilton Rating Scale for Depression, a DSM-IV MDD checklist, and a blinded review of symptom exacerbations by a consensus committee of research clinicians.

RESULTS

Application of a competing-risk model that estimated the conditional probability of recurrence among those patients remaining on active therapy revealed a significant (p =.043) difference between nefazodone (n = 76) and placebo (n = 74) when the latter part of the 1-year maintenance period was emphasized. At the end of 1 year, the conditional probability of recurrence was 30.3% for nefazodone-treated patients, compared with 47.5% for placebo-treated patients. Prior concomitant psychotherapy during acute/continuation treatment, although enhancing the initial response, was not associated with lower recurrence rates. Discontinuations due to adverse events were relatively low for both nefazodone (5.3%) and placebo (4.8%). Somnolence was significantly greater among the patients taking active medication (15.4%), compared with placebo (4.6%).

CONCLUSIONS

Nefazodone is well-tolerated and is an effective maintenance therapy for chronic forms of MDD.

The 16-Item Quick Inventory of Depressive Symptomatology (QIDS), clinician rating (QIDS-C), and self-report (QIDS-SR): a psychometric evaluation in patients with chronic major depression

The 16-item Quick Inventory of Depressive Symptomatology (QIDS), a new measure of depressive symptom severity derived from the 30-item Inventory of Depressive Symptomatology (IDS), is available in both self-report (QIDS-SR(16)) and clinician-rated (QIDS-C(16)) formats. This report evaluates and compares the psychometric properties of the QIDS-SR(16) in relation to the IDS-SR(30) and the 24-item Hamilton Rating Scale for Depression (HAM-D(24)) in 596 adult outpatients treated for chronic nonpsychotic, major depressive disorder. Internal consistency was high for the QIDS-SR(16) (Cronbach's alpha =.86), the IDS-SR(30) (Cronbach's alpha =.92), and the HAM-D(24) (Cronbach's alpha =.88). QIDS-SR(16) total scores were highly correlated with IDS-SR(30) (.96) and HAM-D(24) (.86) total scores. Item-total correlations revealed that several similar items were highly correlated with both QIDS-SR(16) and IDS-SR(30) total scores. Roughly 1.3 times the QIDS-SR(16) total score is predictive of the HAM-D(17) (17-item version of the HAM-D) total score. The QIDS-SR(16) was as sensitive to symptom change as the IDS-SR(30) and HAM-D(24), indicating high concurrent validity for all three scales. The QIDS-SR(16) has highly acceptable psychometric properties, which supports the usefulness of this brief rating of depressive symptom severity in both clinical and research settings.

Patient's therapeutic skill acquisition and response to psychotherapy, alone or in combination with medication

BACKGROUND

We tested the hypotheses that the addition of medication to psychotherapy enhances participation in the latter by: (1) speeding the acquisition of the psychotherapy's targeted skill; and (2) facilitating higher skill level acquisition.

METHOD

Participants were 431 chronically depressed patients who received Cognitive Behavioral Analysis System of Psychotherapy (CBASP), alone (N=214) or in combination with nefazodone (N=217), as part of a randomized chronic depression study (Keller et al. 2000). CBASP, developed specifically to treat chronic depression, uses a specific procedure, 'situational analysis' to help patients engage in more effective goal-oriented interpersonal behaviours. At the end of each session, therapists rated patients on their performance of situational analysis. Outcome on depressive symptoms was assessed with the 24-item Hamilton Rating Scale for Depression.

RESULTS

Although reductions in depression were significantly greater in combined treatment compared to CBASP alone, there were no between-group differences in either the rate of skill acquisition or overall skill level at the end of treatment. Proficiency in the use of the main skill taught in psychotherapy at treatment midpoint predicted outcome independently of medication status and of baseline depressive severity.

CONCLUSIONS

Effective participation in CBASP, as reflected by proficiency in the compensatory skill taught in psychotherapy, is not enhanced by the addition of medication and does not mediate the between-group difference in depression outcome.

Therapeutic Alliance in Depression Treatment: Controlling for Prior Change and Patient Characteristics

Although many studies report that the therapeutic alliance predicts psychotherapy outcome, few exclude the possibility that this association is accounted for by 3rd variables, such as prior improvement and prognostically relevant patient characteristics. The authors treated 367 chronically depressed patients with the cognitive-behavioral analysis system of psychotherapy (CBASP), alone or with medication. Using mixed effects growth-curve analyses, they found the early alliance significantly predicted subsequent improvement in depressive symptoms after controlling for prior improvement and 8 prognostically relevant patient characteristics. In contrast, neither early level nor change in symptoms predicted the subsequent level or course of the alliance. Patients receiving combination treatment reported stronger alliances with their psychotherapists than patients receiving CBASP alone. However, the impact of the alliance on outcome was similar for both treatment conditions.

Continuation treatment of chronic depression: a comparison of nefazodone, cognitive behavioral analysis system of psychotherapy, and their combination

Little is known about the relative benefits of psychotherapy, medication, and combined treatment as continuation therapies for chronic forms of major depressive disorder (MDD) after a positive response to acute treatment. We hypothesize that combined treatment would demonstrate superior continuation phase outcomes compared to either monotherapy, as evidenced by lower relapse rates and greater rates of improvement from partial to full remission. We report 16-week continuation phase outcomes for 324 patients who had participated in either the acute phase of a randomized multicenter trial of nefazodone, Cognitive Behavioral Analysis System of Psychotherapy (CBASP), or combination therapy (COMB) for chronic forms of MDD. Patients entering the continuation phase had either fully or partially remitted after 12 weeks of acute phase treatment. The primary efficacy measure was the 24-item Hamilton Rating Scale for Depression. For patients in remission at acute phase exit, 73.3% (107/146) maintained their remitted status at endpoint of the continuation phase. Of those having a partial remission at acute phase exit, 52.9% (92/174) achieved full remission by end of continuation. A greater proportion of patients maintained a partial or full remission status on COMB (90%) compared to nefazodone (80%, p=0.011) or to CBASP (82%, p=0.042). These differences reflected greater symptom re-emergence in the partial remission groups on CBASP and nefazodone monotherapy compared to COMB. Continuation treatment assignment was not randomized or blinded. There was no placebo group. Most patients with chronic forms of MDD sustained their acute phase response and more than 50% of partial remitters achieved full remission while continuing treatment with nefazodone, CBASP, or COMB. COMB was associated with less symptom re-emergence during the continuation phase than either monotherapy, particularly for partial remitters.

Emotional experiencing: to facilitate or regulate?

In the preceding several decades, both empirical research and advances in the theoretical literatures of diverse schools of thought suggest that greater client in-session emotional experiencing is related to therapeutic change. What has yet to be explored and explicated are the variables that indicate when, and with whom, facilitating emotional experiencing may be most and least helpful. This article offers an exploration of the clinical and empirical literatures that bear on this issue. It also suggests preliminary client and therapist variables that point either toward or away from the therapeutic facilitation of client emotional experiencing.

Private high school students are at risk for bulimic pathology

The objective of this study was to assess whether private high school students constitute a group that is at high risk for eating pathology. Female and male public and private high school students (N = 465) were compared on self-reported eating disordered attitudes and behaviors. Private high school students reported elevated eating disordered attitudes and behaviors when compared with students from public schools. The results were somewhat stronger for females than males. The findings suggest that private high school students are a group at high risk for eating pathology. The identification of such high risk groups may facilitate etiologic studies and aid in the implementation of targeted prevention programs.

The relationship of childhood sexual abuse and depression with somatic symptoms and medical utilization

BACKGROUND

Previous research suggests that childhood sexual abuse is associated with high rates of retrospectively reported medical utilization and medical problems as an adult. The goal of this study was to determine if abused females have higher rates of medical utilization using self-report and objective measures, compared with non-abused females. A further goal was to determine whether findings of prior research would be replicated when childhood physical abuse level was controlled. This study also examined the moderating impact of depressed mood on current health measures in this population.

METHODS

Six hundred and eight women recruited from a health maintenance organization completed self-report measures of health symptoms for the previous month and doctor visits for the previous year. Objective doctor records over a 2 year period were examined for a subset of 136 of these women.

RESULTS

Results showed significantly more self-reported health symptoms and more self-reported doctor visits in abused participants compared with those who reported no childhood history of sexual abuse. Objective doctor visits demonstrated the same pattern with abused participants exhibiting more visits related to out-patient surgery and out-patient internal medicine. In addition, persons who were both sexually abused and depressed tended to visit the emergency room more frequently and to have more in-patient internal medicine and ophthalmology visits than sexually abused participants who reported low depressed mood and non-abused controls.

CONCLUSIONS

These results replicate prior studies and suggest that current depression may moderate the relationship between sexual abuse and medical problems in adulthood.

A comparison of nefazodone, the cognitive behavioral-analysis system of psychotherapy, and their combination for the treatment of chronic depression

BACKGROUND

Patients with chronic forms of major depression are difficult to treat, and the relative efficacy of medications and psychotherapy is uncertain.

METHODS

We randomly assigned 681 adults with a chronic nonpsychotic major depressive disorder to 12 weeks of outpatient treatment with nefazodone (maximal dose, 600 mg per day), the cognitive behavioral-analysis system of psychotherapy (16 to 20 sessions), or both. At base line, all patients had scores of at least 20 on the 24-item Hamilton Rating Scale for Depression (indicating clinically significant depression). Remission was defined as a score of 8 or less at weeks 10 and 12. For patients who did not have remission, a satisfactory response was defined as a reduction in the score by at least 50 percent from base line and a score of 15 or less. Raters were unaware of the patients' treatment assignments.

RESULTS

Of the 681 patients, 662 attended at least one treatment session and were included in the analysis of response. The overall rate of response (both remission and satisfactory response) was 48 percent in both the nefazodone group and in the psychotherapy group, as compared with 73 percent in the combined-treatment group. (P<0.001 for both comparisons). Among the 519 subjects who completed the study, the rates of response were 55 percent in the nefazodone group and 52 percent in the psychotherapy group, as compared with 85 percent in the combined-treatment group (P<0.001 for both comparisons). The rates of withdrawal were similar in the three groups. Adverse events in the nefazodone group were consistent with the known side effects of the drug (e.g., headache, somnolence, dry mouth, nausea, and dizziness).

CONCLUSIONS

Although about half of patients with chronic forms of major depression have a response to short-term treatment with either nefazodone or a cognitive behavioral-analysis system of psychotherapy, the combination of the two is significantly more efficacious than either treatment alone.

Psychologists' beliefs about the prevalence of childhood sexual abuse: the influence of sexual abuse history, gender, and theoretical orientation

OBJECTIVE

This study examined the influence of sexual abuse history, gender, theoretical orientation, and age on beliefs about the prevalence of childhood sexual abuse among clinical and counseling psychologists.

METHOD

A mail survey design was used in this study. Participants were randomly selected from the American Psychological Association membership database. There were 615 psychologists who completed self-report measures on beliefs about the prevalence of childhood sexual abuse and demographic characteristics.

RESULTS

Overall, clinicians' scores on the prevalence of childhood sexual abuse were moderate. There were significant gender differences on beliefs, suggesting that women were more likely believe that childhood sexual abuse is a common occurrence compared to men. Multiple regression analysis indicated that clinician characteristics (history of sexual abuse, gender, and theoretical orientation) were significantly related to beliefs about the prevalence of childhood sexual abuse. However, these characteristics only accounted for a small amount of the overall variance predicting beliefs.

CONCLUSIONS

These results suggest that clinicians do not hold extreme beliefs regarding the prevalence of childhood sexual abuse. Moreover, certain clinician characteristics are associated with their beliefs, which in turn, may impact their clinical judgment and treatment decisions. Furthermore, much of the variance was unaccounted for in the model indicating that psychologists' beliefs are complex and are not unduly influenced by their personal characteristics. Implications for clinical practice and future research are discussed.

The effects of extending cognitive-behavioral therapy for binge eating disorder among initial treatment nonresponders

OBJECTIVE

The study was designed with the aim of determining whether extending group cognitive-behavioral therapy (CBT) would enhance outcome among individuals with binge eating disorder (BED) who failed to stop binge eating after an initial 12-week CBT intervention.

METHOD

Forty-six participants who met diagnostic criteria for BED were randomly allocated to either a 12-week group CBT intervention or a waiting list control condition. At the end of 12 weeks, treated participants who met clinical criteria for improvement subsequently received 12 sessions of behavioral weight loss. Remaining participants received 12 additional sessions of CBT for binge eating.

RESULTS

Fifty percent of treated participants improved with the initial 12-week course of CBT. There was a strong trend for the extension of CBT to affect improvement in binge eating among initial nonresponders (6 of 14 subjects no longer met diagnostic criteria for BED). Overall, extending CBT led to clinical improvement in 66.7% of all treated participants, with treatment gains occurring through session 20.

DISCUSSION

The results suggest that an extended course of CBT (i.e., longer than 12 weeks) will likely maximize the number of potential responders to treatment.

One-year follow-up of cognitive-behavioral therapy for obese individuals with binge eating disorder

The results of a 1-year posttreatment follow-up of 93 obese women diagnosed as having binge eating disorder (BED) and treated with group cognitive-behavioral therapy (CBT) followed by weight loss treatment are described. The group as a whole maintained both reductions in binge eating and abstinence rates fairly well. However, they regained the weight lost during treatment. Those who stopped binge eating during CBT maintained a weight loss of 4.0 kg over the follow-up period. In contrast, those who continued to binge gained 3.6 kg. Twenty-six percent of those abstinent after CBT met criteria for BED at follow-up and had gained weight, whereas the remaining 74% had lost weight. Stopping binge eating appears critical to sustained weight loss in BED.

The aversiveness of specific emotional states associated with binge-eating in obese subjects

OBJECTIVE

The aim of this study was to examine the hypothesis that non-purge-related binge-eating in obesity is maintained by a 'trade-off' in which a highly aversive emotional state is exchanged for a less aversive state.

METHOD

Ninety-eight obese binge-eaters meeting the DSM-IV criteria for binge-eating disorder were contrasted with 65 non-binge-eating controls on their perceived distress associated with negative mood states usually experienced before and after binges.

RESULTS

Binge-eaters reported significantly greater distress and lower tolerance of negative mood compared to controls. Furthermore, when compared with controls, binge-eaters reported that emotions typically reported before binges (e.g. anger) were more aversive than those reported after (e.g. guilt).

CONCLUSIONS

These results were interpreted as supporting the 'trade-off' theory and have implications for the treatment of binge-eating disorder.

Comparing the cost effectiveness of psychiatric treatments: bulimia nervosa

We conducted an exploratory post hoc study that compared the cost effectiveness of five treatments for bulimia nervosa: 15 weeks of cognitive behavioral therapy (CB) followed by three monthly sessions, 16 weeks (Med16) and 24 weeks (Med24) of desipramine (< or = 300 mg/day), and CB combined with desipramine for those durations (Combo16 and Combo24). We illustrate how a treatment's cost effectiveness varies according to when evaluation is done and how effectiveness and cost are defined. At 32 weeks, Med16 appears the most cost-effective treatment, and Combo16 appears the least. At 1 year, Med24 appears the most cost-effective treatment, and Combo16 appears the least. Using this post hoc analysis as an example, we discuss the pitfalls and limitations of cost-effectiveness analysis of psychiatric treatments.

Does interpersonal therapy help patients with binge eating disorder who fail to respond to cognitive-behavioral therapy?

The aim of this quasi-experimental study was to examine the effectiveness of group interpersonal therapy (IPT) in treating overweight patients with binge eating disorder who did not stop binge eating after 12 weeks of group cognitive-behavioral therapy (CBT). Participants in this study were randomly allocated to either group CBT or to an assessment-only control group. After 12 weeks of treatment with CBT, 55% of participants met criteria for improvement and began 12 weeks of weight loss therapy, whereas the nonresponders began 12 weeks of group IPT. Over the 24-week period, participants who received treatment reduced binge eating and weight significantly more than the waiting-list control group. However, IPT led to no further improvement for those who did not improve with CBT. Predictors of poor outcome were early onset of, and more severe, binge eating.

The Emotional Eating Scale: the development of a measure to assess coping with negative affect by eating

The development of the Emotional Eating Scale (EES) is described. The factor solution replicated the scale's construction, revealing Anger/Frustration, Anxiety, and Depression subscales. All three subscales correlated highly with measures of binge eating, providing evidence of construct validity. None of the EES subscales correlated significantly with general measures of psychopathology. With few exceptions, changes in EES subscales correlated with treatment-related changes in binge eating. In support of the measure's discriminant efficiency, when compared with obese binge eaters, subscale scores of a sample of anxiety-disordered patients were significantly lower. Lack of correlation between a measure of cognitive restraint and EES subscales suggests that emotional eating may precipitate binge episodes among the obese independent of the level of restraint.

Does interpersonal therapy help patients with binge eating disorder who fail to respond to cognitive-behavioral therapy?

The aim of this quasi-experimental study was to examine the effectiveness of group interpersonal therapy (IPT) in treating overweight patients with binge eating disorder who did not stop binge eating after 12 weeks of group cognitive-behavioral therapy (CBT). Participants in this study were randomly allocated to either group CBT or to an assessment-only control group. After 12 weeks of treatment with CBT, 55% of participants met criteria for improvement and began 12 weeks of weight loss therapy, whereas the nonresponders began 12 weeks of group IPT. Over the 24-week period, participants who received treatment reduced binge eating and weight significantly more than the waiting-list control group. However, IPT led to no further improvement for those who did not improve with CBT. Predictors of poor outcome were early onset of, and more severe, binge eating.

The last supper: emotional determinants of pretreatment weight fluctuation in obese binge eaters

The tendency of some dieters to overeat and gain weight prior to beginning a diet is well known. We examined whether emotional variables might account for this phenomenon among a group of 86 obese individuals preparing to begin a treatment program for binge eating and weight loss. Whereas subjects' baseline mood state (anger, anxiety, and depression) did not influence pretreatment weight variability, the self-reported tendency to overeat in response to specific negative emotions had a significant influence. Specifically, subjects who characteristically overeat in response to anger and depression gained weight pretreatment, whereas subjects who overeat in response to anxiety lost weight. The findings are discussed in relation to the influence of specific cognitive and emotional responses to the prospect of dieting.

One-year follow-up of psychosocial and pharmacologic treatments for bulimia nervosa

BACKGROUND

This study examined the outcome 1-year posttreatment of the use of desipramine, cognitive-behavioral therapy (CBT), and their combination in the treatment of bulimia nervosa.

METHOD

Sixty-one patients meeting DSM-III-R criteria for bulimia nervosa were randomly assigned to one of five groups--desipramine (withdrawn at 16 or 24 weeks), CBT (18 sessions), or the combined treatment (18 sessions of CBT plus desipramine withdrawn at 16 or 24 weeks)--and were followed to 1-year posttreatment.

RESULTS

At 1-year follow-up, both the combined 24-week treatment and CBT alone were significantly superior in reducing binge eating to desipramine given for 16 weeks. The combined treatment was also superior to 16 weeks of desipramine in reducing emotionally driven eating and dietary restraint. Only 18% (2 of 11) of those receiving 16 weeks of desipramine were free of binge eating and purging at follow-up compared with 78% (7 of 9) of those receiving the combined 24-week treatment. The other groups fell between these two extremes.

CONCLUSION

With the exception of the group treated for 16 weeks with desipramine alone, maintenance of improvement appeared satisfactory with all the treatments. Since the poorest results were found with 16 weeks of desipramine treatment, this study suggests that desipramine should be continued for at least 24 weeks either alone or combined with CBT. The broadest gain in reducing the psychopathology associated with bulimia nervosa was found with the combined 24-week treatment.

Binge eating among the obese: a descriptive study

Nineteen obese females applying for treatment for binge eating were administered a semistructured interview assessing the presence or absence of food restrictions, thoughts, feelings and physical sensations associated with binges, typical precipitants to binges, and factors identified as useful in avoiding binge eating. Both negative mood and abstinence violations emerged as important precipitants. The results also suggested that these precipitants constitute separate, independent pathways to binge eating. Implications of these findings with respect to restraint theory are discussed.

Pharmacologic and cognitive-behavioral treatment for bulimia nervosa: a controlled comparison

OBJECTIVE

This study examined the relative effectiveness of desipramine, cognitive-behavioral therapy, and their combination in the treatment of bulimia nervosa, together with the effects of withdrawing medication after two different lengths of treatment.

METHOD

Seventy-one patients meeting DSM-III-R criteria for bulimia nervosa, recruited from an eating disorders clinic or by advertisements, were assigned at random to one of five groups: desipramine (withdrawn at 16 or 24 weeks), combined treatment (medication withdrawn at 16 or 24 weeks), and cognitive-behavioral therapy (15 sessions). All treatments were conducted individually in an outpatient clinic. The primary outcome measures were binge eating and purging rates assessed at pretreatment, 16, 24, and 32 weeks. The results were analyzed as three groups (medication, cognitive-behavioral therapy, and combined treatment) at 16 weeks and as five groups at subsequent assessments.

RESULTS

At 16 weeks, both cognitive-behavioral therapy and the combined treatment were superior to medication given for 16 weeks in reducing binge eating and purging. At 32 weeks, however, only the combined 24-week treatment was superior to medication given for 16 weeks. The combined treatment was also more effective in reducing dietary preoccupation and hunger. Continuing cognitive-behavioral therapy appeared to prevent relapse in patients withdrawn from medication at 16 weeks.

CONCLUSIONS

Overall, the results favor the use of a combination of medication and cognitive-behavioral therapy in the treatment of bulimia nervosa, with medication continued for at least 24 weeks.

Guttman scaling in agoraphobia: cross-cultural replication and prediction of treatment response patterns

The Fear and Avoidance Scales (FAS) is an 11-item questionnaire consisting of two subscales that measure features of agoraphobia and claustrophobia and that were demonstrated to be valid Guttman scales in a British clinical population. The purposes of the study reported here were to replicate the scale characteristics in the United States and to determine if improvement during treatment would follow the sequence predicted by the hierarchy implied in the scales. The FAS was given to 25 female agoraphobics before and after behavioural treatment. A principal components analysis replicated the agoraphobia and claustrophobia factors established in the British sample. Scalogram analyses showed that the Claustrophobia subscale of the FAS was a valid Guttman scale in the US sample whereas the Agoraphobia subscale yielded a high coefficient of reproducibility but a low coefficient of scalability. Treatment reduced the patients' fears and avoidances in the predicted sequence since for both scales the hierarchy of items remained unchanged following treatment.

Cognitive-behavioral treatment with and without exposure plus response prevention in the treatment of bulimia nervosa: a reply to Leitenberg and Rosen

In this reply to Leitenberg and Rosen (1989), we conclude that the evidence that response prevention of vomiting adds significantly to the efficacy of cognitive-behavioral treatment of bulimia nervosa is not strong. In this context and given the finding in our previous study (Agras, Schneider, Arnow, Raeburn, & Telch, 1989) that the addition of response prevention did not increase the efficacy of cognitive-behavioral treatment and may have reduced it, we believe that our cautionary note concerning the addition of response prevention to cognitive-behavioral treatment should stand.

Cognitive-behavioral and response-prevention treatments for bulimia nervosa

This study was designed to assess the additive effects of major components of cognitive-behavioral treatment for bulimia nervosa. Seventy-seven female patients with bulimia nervosa were allocated at random to one of four conditions: wait-list control, self-monitoring of caloric intake and purging behaviors, cognitive-behavioral treatment, and cognitive-behavioral treatment combined with response prevention of vomiting. In the treatment conditions, participants were seen individually for fourteen 1-hr sessions over a 4-month period. All the treatment groups showed significant improvement, whereas the wait-list control group did not. Cognitive-behavioral treatment was, however, the most successful in reducing purging and in promoting positive psychological changes. Fifty-six percent of participants in this condition ceased binge eating and purging by the end of treatment, and the frequency of purging declined by 77.2% during the same period. Of the three treatment conditions, only cognitive-behavioral treatment was superior to the wait-list control. At the 6-month follow-up, 59% of the cognitive-behavioral group were abstinent, and purging had declined by 80%. Cognitive-behavioral treatment was significantly superior to the other treatment groups at this time. Thus, the addition of response prevention of vomiting did not enhance the efficacy of cognitive-behavioral treatment, and the evidence suggests that it may have had a deleterious effect.

Developing measures of type A behavior in children and adolescents

Development of measures of Type A behavior in children and adolescents is described and the results of two studies to validate these measures are given. Children in the fifth, seventh, and ninth grades (n = 120 in Study I; n = 652 in Study II) were given five measures of the Type A Behavior Pattern (TABP): the Student Type A Behavior Scale (STABS); Student Structured Interviews (SSI), scored separately for content and behavior; Matthews Youth Test for Health (MYTH); and Parent Observation Checklist, as well as measures of state anxiety, trait anxiety, and depression. Descriptive statistics from the two samples were very similar and indicated that boys scored significantly higher than girls on the MYTH, while seventh and ninth grade girls scored significantly higher than fifth grade girls or boys of any grade on Structured Interview Behavior (SSI-Behavior). Correlations suggested separate self-reported perceptual and behavioral components of Type A behavior in children. In both studies, STABS and SSI-Content correlated moderately well (.48 to .49) but had little relationship with SI-Behavior and the MYTH. Measures of anxiety and depression included to assess discriminant validity were correlated with the self-report measures of TABP (.22 to .56), but showed little relationship with the behavioral measures, especially in the larger cross-validation study. Parallels between these results and those of adult studies are discussed, and the use of multiple measures in classifying subjects is suggested.

Physical health correlates of type A behavior in children and adolescents

A physical examination including resting blood pressure, heart rate, Tanner scales, height, and weight was administered to 184 students in the fifth, seventh, and ninth grades. They completed the Physical Symptoms of Stress Inventory, Health Habits Inventory, and two self-monitoring logs of physical symptoms. School absenteeism, medical records, physician ratings, and family health history data were collected. No significant differences between high- and low-Type A behavior pattern (TABP) subjects were found on any of the physical measurements. However, retrospective and prospective reports of physical symptoms revealed a consistent pattern: high TABP subjects reported significantly more physical symptoms than low-TABP subjects. Self-ratings of stress and tension were significantly higher for high-TABP subjects. High-TABP subjects, however, neither missed more school because of illness nor used physician services more often than low subjects. Further, expected relationships between physical symptoms and illness behavior, including school absence, were evident only for low subjects.
