Evidence-based psychological treatments for late-life anxiety

This project identified evidence-based psychotherapy treatments for anxiety disorders in older adults. The authors conducted a review of the geriatric anxiety treatment outcome literature by using specific coding criteria and identified 17 studies that met criteria for evidence-based treatments (EBTs). These studies reflected samples of adults with generalized anxiety disorder (GAD) or samples with mixed anxiety disorders or symptoms. Evidence was found for efficacy for 4 types of EBTs. Relaxation training, cognitive-behavioral therapy (CBT), and, to a lesser extent, supportive therapy and cognitive therapy have support for treating subjective anxiety symptoms and disorders. CBT for late-life GAD has garnered the most consistent support, and relaxation training represents an efficacious, relatively low-cost intervention. The authors provide a review of the strengths and limitations of this research literature, including a discussion of common assessment instruments. Continued investigation of EBTs is needed in clinical geriatric anxiety samples, given the small number of available studies. Future research should examine other therapy models and investigate the effects of psychotherapy on other anxiety disorders, such as phobias and posttraumatic stress disorder in older adults.

Age at onset and clinical features of late life compulsive hoarding

Compulsive hoarding is a debilitating, chronic disorder, yet we know little about its onset, clinical features, or course throughout the life span. Hoarding symptoms often come to clinical attention when patients are in late life, and case reports of elderly hoarders abound. Yet no prior study has examined whether elderly compulsive hoarders have early or late onset of hoarding symptoms, whether their hoarding symptoms are idiopathic or secondary to other conditions, or whether their symptoms are similar to compulsive hoarding symptoms seen in younger and middle‐aged populations. The objectives of this study were to determine the onset and illustrate the course and clinical features of late life compulsive hoarding, including psychiatric and medical comorbitities.

Acceptance and Commitment Therapy for Generalized Anxiety Disorder in Older Adults: A Preliminary Report

Some evidence suggests that acceptance-based approaches such as Acceptance and Commitment Therapy (ACT) may be well-suited to geriatric generalized anxiety disorder (GAD). The primary goal of this project was to determine whether ACT was feasible for this population. Seven older primary-care patients with GAD received 12 individual sessions of ACT; another 9 were treated with cognitive-behavioral therapy. No patients dropped out of ACT, and worry and depression improved. Findings suggest that ACT may warrant a large-scale investigation with anxious older adults.

Meta-Analysis Comparing Different Behavioral Treatments for Late-Life Anxiety

OBJECTIVE To evaluate the efficacy of different types of behavioral treatments for geriatric anxiety (cognitive behavior therapy [CBT] alone, CBT with relaxation training [RT], and RT alone). METHOD The authors compared effect sizes from 19 trials. Analyses were based on uncontrolled outcomes (comparing posttreatment and pretreatment scores) and effects relative to control conditions on both anxiety and depressive symptoms. RESULTS Treatments for older adults with anxiety symptoms were, on average, more effective than active control conditions. Effect sizes were comparable to those reported elsewhere for CBT for anxiety in the general population or for pharmacotherapy in anxious older adults. CBT (alone or augmented with RT) does not seem to add anything beyond RT alone, although a direct comparison is challenging given differences in control conditions. Effects on depressive symptoms were smaller, with no differences among treatment types. CONCLUSION Results suggest that behavioral treatments are effective for older adults with anxiety disorders and symptoms. Results must be interpreted with caution given the limitations of the literature, including differing sample characteristics and control conditions across studies.

Randomized clinical trial of adapted mindfulness-based stress reduction versus group cognitive behavioral therapy for heterogeneous anxiety disorders

OBJECTIVE To compare a mindfulness-based intervention with cognitive behavioral therapy (CBT) for the group treatment of anxiety disorders. METHOD One hundred five veterans (83% male, mean age=46 years, 30% minority) with one or more DSM-IV anxiety disorders began group treatment following randomization to adapted mindfulness-based stress reduction (MBSR) or CBT. RESULTS Both groups showed large and equivalent improvements on principal disorder severity thru 3-month follow up (ps<.001, d=-4.08 for adapted MBSR; d=-3.52 for CBT). CBT outperformed adapted MBSR on anxious arousal outcomes at follow up (p<.01, d=.49) whereas adapted MBSR reduced worry at a greater rate than CBT (p<.05, d=.64) and resulted in greater reduction of comorbid emotional disorders (p<.05, d=.49). The adapted MBSR group evidenced greater mood disorders and worry at Pre, however. Groups showed equivalent treatment credibility, therapist adherence and competency, and reliable improvement. CONCLUSIONS CBT and adapted MBSR were both effective at reducing principal diagnosis severity and somewhat effective at reducing self-reported anxiety symptoms within a complex sample. CBT was more effective at reducing anxious arousal, whereas adapted MBSR may be more effective at reducing worry and comorbid disorders.

Modular Psychotherapy for Anxiety in Older Primary Care Patients

OBJECTIVE To develop and test a modular psychotherapy protocol in older primary care patients with anxiety disorders. DESIGN Randomized, controlled pilot study. SETTING University-based geriatric medicine clinics. PARTICIPANTS Thirty-one elderly primary care patients with generalized anxiety disorder or anxiety disorder not otherwise specified. INTERVENTION Modular form of psychotherapy compared with enhanced community treatment. MEASUREMENTS Self-reported, interviewer-rated, and qualitative assessments of anxiety, worry, depression, and mental health-related quality of life. RESULTS Both groups showed substantial improvements in anxiety symptoms, worry, depressive symptoms, and mental health-related quality of life. Most individuals in the enhanced community treatment condition reported receiving medications or some other form of professional treatment for anxiety. Across both conditions, individuals who reported major life events or stressors and those who used involvement in activities as a coping strategy made smaller gains than those who did not. CONCLUSIONS Results suggest that modular psychotherapy and other treatments can be effective for anxiety in older primary care patients. Results further suggest that life events and coping through increased activity may play a role in the maintenance of anxiety in older adults.

A meta-analysis of cognitive functioning in older adults with PTSD.

A meta-analysis was conducted to summarize and integrate the literature on the cognitive functioning of older adults with posttraumatic stress disorder (PTSD). We hypothesized that those with PTSD would exhibit worse performance in each of the cognitive domains studied when compared to older adults without PTSD. Major databases were queried and eleven articles met criteria for review. As predicted, there was evidence of worse performance across cognitive measures in older adult samples with PTSD relative to older samples without PTSD. The strongest effect across samples was found for lower test scores in the broad domain of memory among older adults with PTSD, and there was evidence that trauma exposure is uniquely associated with worse performance on tests specific to learning. We outline factors thought to contribute to the interactions among PTSD, cognitive deficits, and the aging process. These findings highlight the need for thorough evaluation of cognitive functioning in older adults with PTSD, particularly in the areas of processing speed, learning, memory, and executive functioning.

Cognitive-behavioral therapy for geriatric compulsive hoarding.

This investigation examined response to a manualized cognitive-behavioral therapy (CBT) protocol for compulsive hoarding (Steketee & Frost, 2007) in a sample of 12 adults over age 65. All participants were cognitively intact, not engaging in any other psychotherapy, and had compulsive hoarding as their primary problem. All received 26 sessions of individual CBT over the course of 17 weeks. The primary outcome measures were the Savings Inventory-Revised and UCLA Hoarding Severity Scale, which were administered at baseline, mid-treatment, post-treatment, and 6-month follow-up. Other outcomes included Clinical Global Impression (CGI) scores, depression, anxiety, disability, and clutter image ratings. Results demonstrated statistically significant changes on hoarding severity and depression. However, only three of the twelve participants were classified as treatment responders at post-treatment, and their gains were not maintained at 6-month follow-up. CGI, anxiety, disability, and clutter ratings were unchanged at post-treatment and follow-up. No participants dropped out, but homework compliance was variable and correlated with decreases in hoarding severity. Findings suggest that older adults with compulsive hoarding may require an enhanced or alternative treatment.

Which treatment worked better for whom? Moderators of group cognitive behavioral therapy versus adapted mindfulness based stress reduction for anxiety disorders

OBJECTIVE Identifying treatment moderators facilitates treatment matching and personalized medicine. No previous studies have investigated treatment moderators for a mindfulness-based versus traditional cognitive behavioral therapy (CBT) for anxiety disorders to determine for whom each is most effective. The current study examined three putative moderators of principal anxiety disorder severity outcomes for adapted mindfulness based stress reduction (MBSR) and group CBT - baseline depression symptoms, anxiety sensitivity, and diagnostic severity. METHOD Seventy-one patients with a DSM-IV anxiety disorder were randomized to adapted MBSR or group CBT and assessed at baseline, post-treatment, and 3-month follow up. RESULTS CBT outperformed adapted MBSR among those with no to mild depressive symptoms and, at post-treatment only, among those with very high anxiety sensitivity. At follow up, adapted MBSR outperformed CBT among those with moderate to severe depressive symptoms and among those with average anxiety sensitivity (for this sample). Baseline severity affected post-treatment outcomes differently in CBT than in adapted MBSR. CONCLUSION Baseline levels of depression, anxiety sensitivity, and to some extent diagnostic severity, differentially moderated outcomes in CBT and adapted MBSR for anxiety disorders. Recommendations and clinical implications are discussed.

Novel Treatment for Geriatric Hoarding Disorder: An Open Trial of Cognitive Rehabilitation Paired with Behavior Therapy

OBJECTIVES To investigate the feasibility of an age-adapted, manualized behavioral treatment for geriatric hoarding. METHODS Participants were 11 older adults (mean age: 66 years) with hoarding disorder. Treatment encompassed 24 individual sessions of psychotherapy that included both cognitive rehabilitation targeting executive functioning and exposure to discarding/not acquiring. Hoarding severity was assessed at baseline, mid-treatment, and posttreatment. RESULTS Results demonstrated clinically and statistically significant changes in hoarding severity at posttreatment. No participants dropped out of treatment. Eight participants were classified as treatment responders, and three as partial responders. Partial responders reported severe/extreme hoarding and psychiatric comorbidities at baseline. CONCLUSIONS The combination of cognitive rehabilitation and exposure therapy is a promising approach in the treatment of geriatric hoarding. Targeting neurocognitive deficits in behavioral therapy for these geriatric patients with hoarding disorder doubled response rates relative to our previous trial of cognitive behavior therapy alone.
