Pharmacotherapy is an effective treatment for generalized anxiety disorder (GAD), but few studies have examined the nature of decline of anxiety and depression during pharmacotherapy for GAD and even fewer studies have examined predictors of symptom decline. This study examined the decline in symptoms of anxiety and depression in patients with GAD during a 6-week open trial of fluoxetine. Growth curve analyses indicated that pharmacotherapy with fluoxetine led to significant declines in symptoms of anxiety and depression over the 6 weeks of treatment. However, the decay slope observed for anxiety symptoms was significantly greater than that for depressive symptoms. Further analyses revealed that the decline in anxiety remained significant after accounting for the changes in symptoms of depression. However, the effect of treatment on depression was no longer significant after controlling for the reduction in anxiety symptoms. Overall anxiety sensitivity (AS) did not moderate the level of reduction in symptoms of anxiety or depression during pharmacotherapy. However, AS specific to physical concerns demonstated a marginal negative association with decline in anxiety and depression. AS specific to social concerns also demonstrated a marginal negative association with decline in anxiety symptoms. These findings suggest that the decline in anxiety symptoms is independent of the decline in symptoms of depression during pharmacotherapy for GAD and specific AS dimensions may predict symptom change in GAD.

Background

It is unclear whether bereaved parents with Complicated Grief (CG) struggle with their grief differently than others with CG. This study addressed this question by comparing CG severity, CG-related symptoms, thoughts and behaviors, and comorbid psychiatric diagnoses of bereaved parents with CG to the diagnoses and symptoms of others with CG.

Methods

Baseline data from 345 participants enrolled in the Healing Emotions After Loss (HEAL) study, a multi-site CG treatment study, were used to compare parents with CG (n=75) to others with CG (n=275). Data from the parent group was then used to compare parents with CG who had lost a younger child (n=24) to parents with CG who had lost an older child (n=34). Demographic and loss-related data were also gathered and used to control for confounders between groups.

Results

Parents with CG demonstrated slightly higher levels of CG (p=0.025), caregiver self-blame (p=0.007), and suicidality (p=0.025) than non-parents with CG. Parents who had lost younger children were more likely to have had a wish to be dead since the loss than parents who had lost older children (p=0.041).

Limitations

All data were gathered from a treatment research study, limiting the generalizability of these results. No corrections were made for multiple comparisons. The comparison of parents who lost younger children to parents who lost older children was limited by a small sample size.

Conclusions

Even in the context of CG, the relationship to the deceased may have a bearing on the degree and severity of grief symptoms and associated features. Bereaved parents with CG reported more intense CG, self-blame, and suicidality than other bereaved groups with CG, though this finding requires confirmation. The heightened levels of suicidal ideation experienced by parents with CG, especially after losing a younger child, suggest the value of routinely screening for suicidal thoughts and behaviors in this group.

Complicated grief (CG) is a debilitating syndrome that can be reliably identified, but there is a paucity of research examining treatment of CG. A targeted psychotherapy for complicated grief (CGT) was recently shown to be efficacious [Shear, K., Frank, E., Houck, P.R., Reynolds, C.F., 3rd, 2005. Treatment of complicated grief: a randomized controlled trial. Journal of the American Medical Association 293, 2601-2608]. We provide a detailed examination of the association of naturalistic pharmacotherapy use with treatment response and study completion in the psychotherapy study. Patients on an antidepressant medication were more likely to complete a full course of CGT (91% vs. 58% completed), while antidepressant use had no effect on completion rates for the comparator, interpersonal psychotherapy (70% vs. 77%). Our naturalistic data underscore the need for prospective, randomized controlled studies of CG pharmacotherapy and psychotherapy alone and in combination.

Complicated grief (CG) is increasingly recognized as a debilitating outcome of bereavement. Given the intensity of the stressor, its chronicity, and its association with depression, it is important to know the impact CG may have on cognitive functioning. This exploratory and descriptive study examined global and domain-specific cognitive functioning in a help-seeking sample of individuals with CG (n = 335) compared to a separately ascertained control sample (n = 250). Cognitive functioning was assessed using the Montreal Cognitive Assessment (MoCA). Controlling for age, sex and education effects, CG participants had lower total MoCA, visuospatial and attention scores relative to control participants. The two groups did not differ significantly in the domains of executive function, language, memory or orientation. Age, sex, and education accounted for much of the variance in MoCA scores, while CG severity and chronicity accounted for a very small percentage of MoCA score variance. Major depression was not a significant predictor of MoCA scores. This study is consistent with previous work demonstrating lower attention and global cognitive performance in individuals with CG compared to control participants. This study newly identifies the visuospatial domain as a target for future studies investigating cognitive functioning in CG.

Background

Sleep quality may be an important, yet relatively neglected, predictor of treatment outcome in cognitive-behavioral therapy (CBT) for anxiety disorders. Specifically, poor sleep quality may impair memory consolidation of in-session extinction learning. We therefore examined sleep quality as a predictor of treatment outcome in CBT for social anxiety disorder and the impact of d-cycloserine (DCS) on this relationship.

Methods

One hundred sixty-nine participants with a primary diagnosis of DSM-IV generalized social anxiety disorder were recruited across three sites. Participants were enrolled in 12 weeks of group CBT. Participants randomly received 50 mg of DCS (n = 87) or pill placebo (n = 82) 1 hr prior to sessions 3-7. Participants completed a baseline measure of self-reported sleep quality and daily diaries recording subjective feelings of being rested upon wakening. Outcome measures including social anxiety symptoms and global severity scores were assessed at each session.

Results

Poorer baseline sleep quality was associated with slower improvement and higher posttreatment social anxiety symptom and severity scores. Moreover, patients who felt more "rested" after sleeping the night following a treatment session had lower levels of symptoms and global severity at the next session, controlling for their symptoms and severity scores the previous session. Neither of these effects were moderated by DCS condition.

Conclusions

Our findings suggest that poor sleep quality diminishes the effects of CBT for social anxiety disorder and this relation is not attenuated by DCS administration. Therapeutic attention to sleep quality prior to initiation of CBT and during the acute treatment phase may be clinically indicated.

Background

Prolonged grief disorder (PGD) is a new diagnosis in the 11th edition of the International Classification of Diseases, estimated to affect 1 in 10 bereaved people and causing significant distress and impairment. Maladaptive thoughts play an important role in PGD. We have previously validated the typical beliefs questionnaire (TBQ), which contains five kinds of thinking commonly seen in PGD: protesting the death, negative thoughts about the world, needing the person, less grief is wrong, and grieving too much. The current paper examines the role of maladaptive cognition as measured by the TBQ in PGD and its change with treatment.

Methods

Among participants in a multisite clinical trial including 394 adults, we examined (a) the relationship between maladaptive thoughts at baseline and treatment outcomes, (b) the relationship between maladaptive thoughts and suicidality at baseline and posttreatment, and (c) the effect of treatment with and without complicated grief therapy (CGT) on maladaptive thinking.

Results

TBQ scores were associated with treatment outcomes and were strongly related to suicidal thinking before and after treatment. TBQ scores showed significantly greater reduction in participants who received CGT with citalopram versus citalopram alone (adjusted mean standard error [SE] difference, -2.45 [0.85]; p = .004) and those who received CGT with placebo versus placebo alone (adjusted mean [SE] difference, -3.44 [0.90]; p < .001).

Conclusions

Maladaptive thoughts, as measured by the TBQ, have clinical and research significance for PGD and its treatment.

The death of a loved one is one of life's greatest stressors. Most bereaved individuals experience a period of acute grief that diminishes in intensity as they adapt to the changes brought about by their loss. Over the past four decades, a growing body of research has focused on a form of prolonged grief that is painful and impairing. There is a substantial and growing evidence base that supports the validity and significance of a grief-related disorder, including the clinical value of being able to diagnose it and provide effective targeted treatment. ICD-11 will include a new diagnosis of prolonged grief disorder (PGD). DSM-5 called this condition persistent complex bereavement disorder (PCBD) and included it in Section III, signaling agreement that a diagnosis is warranted while further research is needed to determine the optimal criteria. Given the remaining uncertainties, reading this literature can be confusing. There is inconsistency in naming the condition (including complicated grief as well as PGD and PCBD) and lack of uniformity in identifying it, with respect to the optimal threshold and timeframe for distinguishing it from normal grief. As an introductory commentary for this Depression and Anxiety special edition on this form of grief, the authors discuss the history, commonalities, and key areas of variability in identifying this condition. We review the state of diagnostic criteria for DSM-5 and the current ICD-11 diagnostic guideline, highlighting the clinical relevance of making this diagnosis.

Background

Posttraumatic stress disorder (PTSD) has been associated with exaggerated threat processing and deficits in emotion modulation circuitry. It remains unknown how neural circuits are associated with response to evidence-based treatments for PTSD.

Method

We examined associations between PTSD symptoms and indicators of neural response in key emotion processing and modulation regions. Fifty-six military Veterans with PTSD were randomly assigned to one of three evidence-based treatments (prolonged exposure, sertraline, and PE plus sertraline) in a randomized clinical trial ("PROGrESS"; 2018, Contemp Clin Trials, 64, 128-138). Twenty-seven combat-exposed controls (CCs) served as a comparison group at pretreatment. Before and after PTSD treatment, functional magnetic resonance imaging was used to assess brain activation and connectivity during the validated Shifted Attention Emotion Appraisal Task (2003, J Neurosci, 23, 5627-5633; 2013, Biol Psychiatry, 73, 1045-1053).

Results

Greater activation in emotion processing (anterior insula) and modulation (prefrontal cortex) regions and increased connectivity between attentional control (dorsolateral prefrontal cortex and superior parietal cortex) and emotion processing (amygdala) regions, at pretreatment, were associated with subsequent PTSD symptom improvement.

Conclusions

This study is one of the first to examine task-based activation and functional connectivity in a PTSD treatment trial, and provides evidence to suggest that activation in and connectivity between emotion processing and modulation regions are important predictors of treatment response.

Objectives

Maladaptive cognitions related to loss are thought to contribute to development of complicated grief and are crucial to address in treatment, but tools available to assess them are limited. This paper introduces the Typical Beliefs Questionnaire (TBQ), a 25-item self-report instrument to assess cognitions that interfere with adaptation to loss.

Design

Study participants completed an assessment battery during their initial evaluation and again after completing treatment at 20 weeks. Test-retest reliability was assessed on a subsample of the participants who did not show change in complicated grief severity after the first 4 weeks of treatment. To examine latent structure of the TBQ, an exploratory factor analysis (EFA) was performed.

Setting

Academic medical centers in Boston, New York, Pittsburgh, and San Diego from 2010-2014.

Participants

394 bereaved adults who met criteria for complicated grief.

Measurements

The TBQ along with assessments of complicated grief symptoms and related avoidance, depression symptoms, functional impairment, and perceived social support.

Results

The TBQ exhibited good internal consistency (α = 0.82) and test-retest reliability (N = 105; intraclass correlation coefficient = 0.74). EFA indicated a five-factor structure: "Protesting the Death," "Negative Thoughts About the World," "Needing the Person," "Less Grief is Wrong" and "Grieving Too Much." The total score and all factors showed sensitivity to change with treatment.

Conclusions

This new tool allows a clinician to quickly and reliably ascertain presence of specific maladaptive cognitions related to complicated grief, and subsequently, to use the information to aid a diagnostic assessment, to structure the treatment, and to measure treatment outcomes.

Since September 11, 2001, more than two million U.S. service members have deployed to Iraq or Afghanistan, many returning home with posttraumatic stress disorder (PTSD) and additional psychological and general medical complaints. Nonetheless, many do not seek care or may not respond to traditional outpatient approaches, warranting innovative, multidisciplinary treatment approaches. To help address these complex needs, the Wounded Warrior Project has funded four academic medical centers to develop a care network across the nation. As part of this Warrior Care Network, the Emory Healthcare Veterans Program in Atlanta; the Home Base Program at Massachusetts General Hospital, in collaboration with the Red Sox Foundation, in Boston; Road Home at Rush Medical Center in Chicago; and Operation Mend at the University of California, Los Angeles, have each developed innovative, intensive programs to treat PTSD among post-9/11 veterans and service members. The programs offer two- to three-week intensive PTSD treatment programs with evidence-based approaches embedded in a broader program. To date, 328 post-9/11 veterans and active-duty service members have received care in these intensive outpatient programs. The average completion rate is approximately 95%, which demonstrates the acceptability of this brief but intensive care model for a complex population who can be challenging to engage or retain in care.
