Loving-kindness meditation for chronic low back pain: Results from a pilot trial

Purpose: Loving-kindness meditation has been used for centuries in the Buddhist tradition to develop love and transform anger into compassion. This pilot study tested an 8-week loving-kindness program for chronic low back pain patients. Method: Patients (N = 43) were randomly assigned to the intervention or standard care. Standardized measures assessed patients’ pain, anger, and psychological distress. Findings: Post and follow-up analyses showed significant improvements in pain and psychological distress in the loving-kindness group, but no changes in the usual care group. Multilevel analyses of daily data showed that more loving-kindness practice on a given day was related to lower pain that day and lower anger the next day. Conclusions: Preliminary results suggest that the loving-kindness program can be beneficial in reducing pain, anger, and psychological distress in patients with persistent low back pain. Implications: Clinicians may find loving-kindness meditation helpful in the treatment of patients with persistent pain.

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.

Exaggerated and Disconnected Insular-Amygdalar Blood Oxygenation Level-Dependent Response to Threat-Related Emotional Faces in Women with Intimate-Partner Violence Posttraumatic Stress Disorder

BACKGROUND Intimate-partner violence (IPV) is one of the most common causes of posttraumatic stress disorder (PTSD) among women. PTSD neuroimaging studies have identified functional differences in the amygdala and anterior cingulate cortex (ACC)/medial prefrontal cortex during emotion processing. Recent investigations of the limbic sensory system and its associated neural substrate, the insular cortex, have demonstrated its importance for emotional awareness. This study examined the hypothesis that women with IPV-PTSD show a dysregulation of this limbic sensory system while processing threat-related emotional faces. METHODS 12 women with IPV-PTSD and 12 nontraumatized comparison women underwent blood oxygenation level-dependent functional magnetic resonance imaging while completing an emotional face-matching task. RESULTS IPV-PTSD subjects relative to comparison subjects displayed increased activation of the anterior insula and amygdala and decreased connectivity among the anterior insula, amygdala, and ACC while matching to fearful versus happy target faces. A similar pattern of activation differences was also observed for angry versus happy target faces. IPV-PTSD subjects relative to comparison subjects also displayed increased dorsal ACC/medial prefrontal cortex activation and decreased ventral ACC activation when matching to a male versus a female target, and the extent of increased dorsal ACC activation correlated positively with hyperarousal symptoms. CONCLUSIONS Women with IPV-PTSD display hyperactivity and disconnection among affective and limbic sensory systems while processing threat-related emotion. Furthermore, hyperactivity of cognitive-appraisal networks in IPV-PTSD may promote hypervigilant states of awareness through an exaggerated sensitivity to contextual cues, i.e., male gender, which relate to past trauma.

Videoconferencing psychotherapy: a systematic review.

Individuals with mental health problems may face barriers to accessing effective psychotherapies. Videoconferencing technology, which allows audio and video information to be shared concurrently across geographical distances, offers an alternative that may improve access. We conducted a systematic literature review of the use of videoconferencing psychotherapy (VCP), designed to address 10 specific questions, including therapeutic types/formats that have been implemented, the populations with which VCP is being used, the number and types of publications related to VCP, and available satisfaction, feasibility, and outcome data related to VCP. After electronic searches and reviews of reference lists, 821 potential articles were identified, and 65 were selected for inclusion. The results indicate that VCP is feasible, has been used in a variety of therapeutic formats and with diverse populations, is generally associated with good user satisfaction, and is found to have similar clinical outcomes to traditional face-to-face psychotherapy. Although the number of articles being published on VCP has increased in recent years, there remains a need for additional large-scale clinical trials to further assess the efficacy and effectiveness of VCP.

Functional activation and neural networks in women with posttraumatic stress disorder related to intimate partner violence

BACKGROUND Intimate partner violence (IPV) is one of the most common causes of posttraumatic stress disorder (PTSD) in women. Victims of IPV are often preoccupied by the anticipation of impending harm. This investigation tested the hypothesis that IPV-related PTSD individuals show exaggerated insula reactivity to the anticipation of aversive stimuli. METHODS Fifteen women with a history of IPV and consequent PTSD (IPV-PTSD) and 15 non-traumatized control (NTC) women performed a task involving cued anticipation to images of positive and negative events during functional magnetic resonance imaging. RESULTS Both groups showed increased activation of bilateral anterior insula during anticipation of negative images minus anticipation of positive images. Activation in right anterior/middle insula was significantly greater in the IPV-PTSD relative to the NTC group. Functional connectivity analysis revealed that changes in activation in right middle insula and bilateral anterior insula were more strongly associated with amygdala activation changes in NTC than in IPV-PTSD subjects. CONCLUSIONS This study revealed increased activation in the anterior/middle insula during negative anticipation in women with IPV-related PTSD. These findings in women with IPV could be a consequence of the IPV exposure, reflect pre-existing differences in insular function, or be due to the development of PTSD. Thus, future longitudinal studies need to examine these possibilities.

Dorsolateral Prefrontal Cortex Activation During Emotional Anticipation and Neuropsychological Performance in Posttraumatic Stress Disorder

CONTEXT Posttraumatic stress disorder (PTSD) has been associated with executive or attentional dysfunction and problems in emotion processing. However, it is unclear whether these two domains of dysfunction are related to common or distinct neurophysiological substrates. OBJECTIVE To examine the hypothesis that greater neuropsychological impairment in PTSD relates to greater disruption in prefrontal-subcortical networks during emotional anticipation. DESIGN Case-control, cross-sectional study. SETTING General community and hospital and community psychiatric clinics. PARTICIPANTS Volunteer sample of 37 women with PTSD related to intimate partner violence and 34 age-comparable healthy control women. MAIN OUTCOME MEASURES We used functional magnetic resonance imaging (fMRI) to examine neural responses during anticipation of negative and positive emotional images. The Clinician-Administered PTSD Scale was used to characterize PTSD symptom severity. The Wechsler Adult Intelligence Scale, Third Edition, Digit Symbol Test, Delis-Kaplan Executive Function System Color-Word Interference Test, and Wisconsin Card Sorting Test were used to characterize neuropsychological performance. RESULTS Women with PTSD performed worse on complex visuomotor processing speed (Digit Symbol Test) and executive function (Color-Word Interference Inhibition/Switching subtest) measures compared with control subjects. Posttraumatic stress disorder was associated with greater anterior insula and attenuated lateral prefrontal cortex (PFC) activation during emotional anticipation. Greater dorsolateral PFC activation (anticipation of negative images minus anticipation of positive images) was associated with lower PTSD symptom severity and better visuomotor processing speed and executive functioning. Greater medial PFC and amygdala activation related to slower visuomotor processing speed. CONCLUSIONS During emotional anticipation, women with PTSD show exaggerated activation in the anterior insula, a region important for monitoring internal bodily state. Greater dorsolateral PFC response in PTSD patients during emotional anticipation may reflect engagement of cognitive control networks that are beneficial for emotional and cognitive functioning. Novel treatments could be aimed at strengthening the balance between cognitive control (dorsolateral PFC) and affective processing (medial PFC and amygdala) networks to improve overall functioning for PTSD patients.

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.

Cognitive impairment and functioning in PTSD related to intimate partner violence.

Posttraumatic stress disorder (PTSD) has been associated with neuropsychological impairments across multiple domains, but consensus regarding the cognitive profile of PTSD has not been reached. In this study of women with PTSD related to intimate partner violence (n = 55) and healthy, demographically similar comparison participants (NCs; n = 20), we attempted to control for many potential confounds in PTSD samples. All participants were assessed with a comprehensive neuropsychological battery emphasizing executive functioning, including inhibition, switching, and abstraction. NCs outperformed PTSD participants on most neuropsychological measures, but the differences were significant only on speeded tasks (with and without executive functioning components). The PTSD groups mean performance was within the average range on all neuropsychological tests. Within the PTSD group, more severe PTSD symptoms were associated with slower processing speed, and more severe dissociative symptoms were associated with poorer reasoning performance. These results suggest that women with PTSD related to intimate partner violence demonstrate slower than normal processing speed, which is associated with the severity of psychiatric symptoms. We speculate that the cognitive slowing seen in PTSD may be attributable to reduced attention due to a need to allocate resources to cope with psychological distress or unpleasant internal experiences.

A Spiritually Based Group Intervention for Combat Veterans With Posttraumatic Stress Disorder Feasibility Study

Purpose: To assess the feasibility, effect sizes, and satisfaction of mantram repetition—the spiritual practice of repeating a sacred word/phrase throughout the day—for managing symptoms of posttraumatic stress disorder (PTSD) in veterans. Design: A two group (intervention vs. control) by two time (pre- and postintervention) experimental design was used. Methods: Veterans were randomly assigned to intervention (n = 14) or delayed-treatment control (n = 15). Measures were PTSD symptoms, psychological distress, quality of life, and patient satisfaction. Effect sizes were calculated using Cohens d. Findings: Thirty-three male veterans were enrolled, and 29 (88%) completed the study. Large effect sizes were found for reducing PTSD symptom severity (d = –.72), psychological distress (d = –.73) and increasing quality of life (d = –.70). Conclusions: A spiritual program was found to be feasible for veterans with PTSD. They reported moderate to high satisfaction. Effect sizes show promise for symptom improvement but more research is needed.
