Providing emotional support to caregivers is integral to comprehensive ALS care. The authors surveyed ALS Association centers and clinics and Muscular Dystrophy Association/ALS centers. Respondents thought that grief and bereavement support was integral to ALS care but thought that the support provided by their centers was often inadequate.
This paper reports on the acceptability, reliability and validity of the Structured Clinical Interview for the Spectrum of Substance Use (SCI-SUBS), a new instrument exploring the interactive pathway between substance abuse and psychiatric disorders. Psychiatric outpatients with (n = 21) and without (n = 32) substance abuse comorbidity according to the DSM-IV, non-psychiatric subjects with opioid dependence (OD, n = 14) and normal controls (n = 33) were assessed with the SCI-SUBS. The presence or absence of psychiatric disorders was determined with the Structured Clinical Interview for DSM IV (SCID). The SCI-SUBS was well accepted by participants. The internal consistency of the domains was satisfactory (between 0.64 and 0.93). Domain scores of OD subjects were significantly higher than those of controls and of psychiatric patients without substance abuse. The cut-off point on the SCI-SUBS total score at which there was optimal discrimination between the presence and the absence of a DSM-IV diagnosis of substance abuse was 45. The pilot version of the SCI-SUBS has satisfactory internal consistency and construct validity.
Given the high rates of maladjustment among children of depressed mothers, parenting is likely to cause significant life stress in this population, potentially worsening the course of mothers' depression. The present study is a comparison of severe life stress in 38 mothers and 62 non-mothers receiving treatment for recurrent major depression. Life stress was assessed using the Life Events and Difficulties Schedule [Brown and Harris, 1978a]. We hypothesized that mothers would evidence a greater number of severe life events and marked difficulties both in the year prior to the onset of their depressive index episode and in the time period following the onset of their current depressive episode. Prior to depression onset, mothers reported a significantly greater number of entrapping difficulties, but not marked difficulties, severe events, entrapping events, or humiliating events. However, following the onset of depression, mothers experienced a significantly greater number of severe events, entrapping events, marked difficulties, and entrapping difficulties, but not humiliating events. Mothers' elevated levels of stress were attributable to child-related stress, predominantly related to children's psychological and behavioral problems. Our findings suggest that comprehensive treatment for mothers with major depression needs to address their parenting style and any psychological problems experienced by their children.
Since psychiatric disorders differ throughout the lifespan in phenomenology, course, and treatment, there is need for study of comorbidity of such disorders in geriatric populations. Prior findings of low prevalence of comorbid late-life anxiety disorders in depressed elderly are now disputed by recent studies. Risk factors for comorbid late-life depression and anxiety may be different from those for depression without anxiety. Similar to adults, elderly depressives with comorbid anxiety symptoms present with more severe pathology and have a more difficult course of illness, including decreased or delayed treatment response. In this paper, we review the literature on anxiety and depression comorbidity in late life, and we make recommendations for the assessment and treatment of comorbid late-life anxiety and depression. We also recommend directions for future research in the area of psychiatric comorbidity in late life.
RATIONALE: There exists a wide range of animal models and measures designed to assess anxiety or fearfulness. However, the relationship between these models and clinical anxiety symptoms and syndromes is unclear. The National Institute of Mental Health convened a workshop to discuss the relationship between existing behavioral models of anxiety and the clinical profile of anxiety disorders. A second goal of this workshop was to outline various approaches towards modeling components of anxiety disorders. OBJECTIVES: To briefly describe epidemiological and behavioral manifestations of clinical anxiety syndromes and how they relate to commonly employed animal models of anxiety. To describe approaches and considerations for developing, improving, and adapting anxiety models to better understand the neurobiology of anxiety. METHODS: Clinicians, psychiatrists and clinical and basic neuroscientists presented data exemplifying different approaches towards understanding anxiety and the role of animal models. Panel members outlined what they considered to be critical issues in developing and employing animal models of anxiety. RESULTS: This review summarizes the discussions and conclusions of the workshop including recommendations for improving upon existing models and strategies for developing novel models. CONCLUSIONS: The probability of developing comprehensive animal models that accurately reflect the relative influences of factors contributing to anxiety disorder syndromes is quite low. However, ample opportunity remains to better define and extend existing models and behavioral measures related to specific processes that may be disrupted in anxiety disorders and to develop new models that consider the impact of combined factors in determining anxious behaviors.
Traumatic grief is a common and debilitating syndrome whose clinical presentation is well recognized but whose diagnostic criteria have only recently been delineated. Though it shares features with major depressive disorder, adjustment disorder, and posttraumatic stress disorder, none of these subsume the criteria set for traumatic grief, and the diagnostic overlap is limited in community samples. Furthermore, diagnosis of traumatic grief appears to have prognostic value for clinical course and treatment response among bereaved individuals. In the absence of empirically supported treatments of pathological grief, a new, manualized treatment for traumatic grief symptoms has been developed and is currently undergoing testing in a randomized controlled trial. The conceptual basis for Traumatic Grief Treatment (TGT) is presented, the structure of the treatment is outlined, and the primary clinical strategies employed are described.
The relationship between therapists and treatment outcome was examined in 14 highly trained therapists who participated in the Multicenter Collaborative Study for the Treatment of Panic Disorder. Overall, therapists yielded positive outcomes in their caseloads; yet, therapists significantly differed in the magnitude of change among caseloads. Effect sizes for therapist impact on outcome measures varied from 0% to 18%. Overall experience in conducting psychotherapy was related to outcome on some measures, whereas age, gender, gender match, and experience with cognitive-behavioral therapy (CBT) were not. Therapists with above- and below-average outcomes were rated similarly on measures of adherence and competency. The results suggest that therapists make a contribution to outcome in CBT for panic disorder, even when patients are relatively uniform, treatment is structured, and outcome is positive. Implications for future clinical outcome studies and for training clinicians are discussed.
OBJECTIVE: Recent studies have suggested that most patients treated for panic disorder receive forms of psychotherapy other than cognitive behavior therapy, even though there is little information about the efficacy of such treatments or how they compare to proven active treatments. The authors compared one of these other forms, emotion-focused psychotherapy (given to 30 patients with panic disorder), to results obtained with recommended standard treatment (either cognitive behavior therapy [N=36] or imipramine [N=22]). The authors also compared emotion-focused psychotherapy to results obtained in subjects given pill placebo (N=24). METHOD: Subjects met DSM-IV criteria for panic disorder with no more than mild agoraphobia. Treatment consisted of approximately 3 months of weekly visits followed by 6 monthly maintenance visits. Assessments were conducted after each treatment phase and at a follow-up visit after 6 months of no treatment. RESULTS: Emotion-focused psychotherapy was less effective for symptoms of panic disorder than treatment with either cognitive behavior therapy or imipramine; results obtained with emotion-focused psychotherapy after the acute and maintenance phases were similar to those seen with placebo. Treatment expectations were not different among the different groups. Patients receiving emotion-focused psychotherapy had the highest completion rate. CONCLUSIONS: The results suggest that emotion-focused psychotherapy (a supportive form of psychotherapy) has low efficacy for the treatment of panic disorder. However, emotion-focused psychotherapy may be superior to medical management in helping patients stay in treatment.

OBJECTIVE: The effects of a treatment program targeting debilitating grief symptoms were tested in a pilot study. METHOD: Twenty-one individuals experiencing traumatic grief were recruited for participation, and 13 completed the full 4-month protocol. The treatment protocol used imaginal re-living of the death, in vivo exposure to avoided activities and situations, and interpersonal therapy. RESULTS: Significant improvement in grief symptoms and associated anxiety and depression was observed for both completer and intent-to-treat groups. CONCLUSIONS: The traumatic grief treatment protocol appears to be a promising intervention for debilitating grief.
BACKGROUND: Traumatic grief has been found to be a distinct disorder from both depression and anxiety; however, there is no information in the literature regarding comorbidity of traumatic grief with other psychiatric disorders. METHOD: Twenty-three bereaved subjects who presented for treatment of traumatic grief symptomatology were included in this study. The Inventory of Complicated Grief (ICG) was used to confirm the presence of traumatic grief and assess its severity. In addition, the Structured Clinical Interview for DSM-IV was performed. RESULTS: Most subjects met criteria for a current or lifetime Axis I diagnosis. Fifty-two percent (N = 12) met criteria for current major depressive disorder, and 30% (N = 7), for current posttraumatic stress disorder (PTSD). ICG scores and functional impairment were higher among patients with more than one concurrent Axis I diagnosis. CONCLUSION: Comorbid major depressive disorder and PTSD may be prevalent in patients presenting for treatment of traumatic grief.
The Hamilton Anxiety Rating Scale, a widely used clinical interview assessment tool, lacks instructions for administration and clear anchor points for the assignment of severity ratings. We developed a Structured Interview Guide for the Hamilton Anxiety Scale (SIGH-A) and report on a study comparing this version to the traditional form of this scale. Experienced interviewers from three Anxiety Disorders research sites conducted videotaped interviews using both traditional and structured instruments in 89 participants. A subset of the tapes was co-rated by all raters. Participants completed self-report symptom questionnaires. We observed high inter-rater and test-retest reliability using both formats. The structured format produced similar but consistently higher (+ 4.2) scores. Correlation with a self-report measure of overall anxiety was also high and virtually identical for the two versions. We conclude that in settings where extensive training is not practical, the structured scale is an acceptable alternative to the traditional Hamilton Anxiety instrument.
This is a complete report of an open trial of manualized psychodynamic psychotherapy for treatment of panic disorder, Panic-Focused Psychodynamic Psychotherapy (PFPP). Twenty-one patients with PD were entered into a trial of twice-weekly, 24-session treatment. Sixteen of 21 experienced remission of panic and agoraphobia. Treatment completers with depression also experienced remission of depression. Improvements in symptoms and in quality of life were substantial and consistent across all measured areas. Symptomatic gains were maintained over 6 months. This report was prepared specifically to describe 6-month follow-up on these patients. Psychodynamic psychotherapy appears to be a promising nonpharmacological treatment for panic disorder.
In the past, many studies attempting to compare pharmacological and psychosocial treatments for mood and anxiety disorders have been conducted by partisans of either approach. More recently, rigorously conducted, unbiased comparative studies have begun to appear. Here we reviewed our own experience in designing and conducting a multicenter study comparing medication and cognitive behavioral therapy and their combination for the treatment of panic disorder.
CONTEXT: Panic disorder (PD) may be treated with drugs, psychosocial intervention, or both, but the relative and combined efficacies have not been evaluated in an unbiased fashion. OBJECTIVE: To evaluate whether drug and psychosocial therapies for PD are each more effective than placebo, whether one treatment is more effective than the other, and whether combined therapy is more effective than either therapy alone. DESIGN AND SETTING: Randomized, double-blind, placebo-controlled clinical trial conducted in 4 anxiety research clinics from May 1991 to April 1998. PATIENTS: A total of 312 patients with PD were included in the analysis. INTERVENTIONS: Patients were randomly assigned to receive imipramine, up to 300 mg/d, only (n=83); cognitive-behavioral therapy (CBT) only (n=77); placebo only (n=24); CBT plus imipramine (n=65); or CBT plus placebo (n=63). Patients were treated weekly for 3 months (acute phase); responders were then seen monthly for 6 months (maintenance phase) and then followed up for 6 months after treatment discontinuation. MAIN OUTCOME MEASURES: Treatment response based on the Panic Disorder Severity Scale (PDSS) and the Clinical Global Impression Scale (CGI) by treatment group. RESULTS: Both imipramine and CBT were significantly superior to placebo for the acute treatment phase as assessed by the PDSS (response rates for the intent-to-treat [ITT] analysis, 45.8%, 48.7%, and 21.7%; P=.05 and P=.03, respectively), but were not significantly different for the CGI (48. 2%, 53.9%, and 37.5%, respectively). After 6 months of maintenance, imipramine and CBT were significantly more effective than placebo for both the PDSS (response rates, 37.8%, 39.5%, and 13.0%, respectively; P=.02 for both) and the CGI (37.8%, 42.1%, and 13.0%, respectively). Among responders, imipramine produced a response of higher quality. The acute response rate for the combined treatment was 60.3% for the PDSS and 64.1% for the CGI; neither was significantly different from the other groups. The 6-month maintenance response rate for combined therapy was 57.1% for the PDSS (P=.04 vs CBT alone and P=.03 vs imipramine alone) and 56.3% for the CGI (P=.03 vs imipramine alone), but not significantly better than CBT plus placebo in either analysis. Six months after treatment discontinuation, in the ITT analysis CGI response rates were 41.0% for CBT plus placebo, 31.9% for CBT alone, 19.7% for imipramine alone, 13% for placebo, and 26.3% for CBT combined with imipramine. CONCLUSIONS: Combining imipramine and CBT appeared to confer limited advantage acutely but more substantial advantage by the end of maintenance. Each treatment worked well immediately following treatment and during maintenance; CBT appeared durable in follow-up. JAMA. 2000;283:2529-2536
Prepubescent boys are, if anything, more likely than girls to be depressed. During adolescence, however, a dramatic shift occurs: between the ages of 11 and 13 years, this trend in depression rates is reversed. By 15 years of age, females are approximately twice as likely as males to have experienced an episode of depression, and this gender gap persists for the next 35 to 40 years. We offer a theoretical framework that addresses the timing of this phenomenon. First, we discuss the social and hormonal mechanisms that stimulate affiliative needs for females at puberty. Next, we describe how heightened affiliative need can interact with adolescent transition difficulties to create a depressogenic diathesis as at-risk females reach puberty. This gender-linked vulnerability explains why adolescent females are more likely than males to become depressed when faced with negative life events and, particularly, life events with interpersonal consequences.
This study seeks to determine how panic disorder patients with anxiety and depression comorbidity differ from panic disorder patients without comorbidity at the time of presentation for treatment. One-hundred seventy-one panic disorder patients presenting for their initial assessment and treatment at the Payne Whitney Anxiety Disorders Clinic agreed to participate and completed self-report and diagnostic assessments. Sixty-seven percent of panic disorder subjects were found to have at least one comorbid anxiety or depression diagnosis. Age and gender ratio were not affected by the presence of comorbid diagnoses. Comorbidity significantly contributed to psychological distress and symptom load, overall impairment, and interpersonal impairment.
BACKGROUND: This study examined the association between a diagnosis of traumatic grief and quality of life outcomes. METHOD. Sixty-seven widowed persons were interviewed at a median of 4 months after their loss. The multiple regression procedure was used to estimate the effects of a traumatic grief diagnosis on eight quality of life domains, controlling for age, sex, time from loss and diagnoses of major depressive episode and post-traumatic stress disorder. RESULTS: A positive traumatic grief diagnosis was significantly associated with lower social functioning scores, worse mental health scores, and lower energy levels than a negative traumatic grief diagnosis. In each of these domains, traumatic grief was found to be a better predictor of lower scores than either major depressive episode or post-traumatic stress disorder. CONCLUSIONS: The results suggest that a traumatic grief diagnosis is significantly associated with quality of life impairments. These findings provide evidence supporting the criterion validity of the proposed consensus criteria and the newly developed diagnostic interview for traumatic grief the Traumatic Grief Evaluation of Response to Loss (TRGR2L).
