The Dissociative Symptoms Scale (DSS) was developed to assess moderately severe types of dissociation (depersonalization, derealization, gaps in awareness and memory, and dissociative reexperiencing) that would be relevant to a range of clinical populations, including those experiencing trauma-related dissociation. The current study used data from 10 ethnically and racially diverse clinical and community samples ( = 3,879) to develop a brief version of the DSS (DSS-B). Item information curves were examined to identify items with the most precision in measuring above average levels of the latent trait within each subscale.

Hate-based violence is increasingly recognized as an urgent social justice and human rights issue that is pervasive across geographical and socioeconomic boundaries. There is a growing body of research that demonstrates the traumatic impact of hate-based violence on the victim's mental and physical health. This review focuses on examining scientific knowledge and prevalence data on identity-based hate and violence exposure.

Veterans with mental health problems and a history of interpersonal and military trauma exposure are at increased risk for chronic homelessness. Although studies have examined posttraumatic stress disorder (PTSD) as a predictor of homelessness, there is limited understanding of specific mechanisms related to cumulative trauma exposure. We sought to elucidate how cumulative interpersonal and military trauma exposure may be linked to homelessness chronicity by examining the role of factors that influence trauma recovery and functional impairment.

This study investigated the psychometric properties of the Dissociative Symptoms Scale (DSS) among Italian adults from outpatient and community samples. The DSS is a self-report measure of clinically relevant dissociation in adults. An Italian translation of the DSS was administered with measures of lifetime traumatic experiences, psychoform dissociation, and somatoform dissociation to 175 psychiatric outpatients and 423 individuals from the community.

Despite advances in psychological interventions for pediatric chronic pain, there has been little research examining mindfulness meditation for these conditions. This study presents data from a pilot clinical trial of a six-week manualized mindfulness meditation intervention offered to 20 adolescents aged 13-17 years. Measures of pain intensity, functional disability, depression and parent worry about their child's pain were obtained at baseline and post-treatment.

Objective: This randomized controlled trial examined the comparative effectiveness of 2 interventions for improving diurnal cortisol slope and life satisfaction and reducing stress symptoms among older female dementia family caregivers.

Method: Thirty-one family dementia caregivers were randomized to 8 weeks of Inner Resources for Stress mindfulness meditation and mantra training (IR) or psychoeducation and telephone support (PTS).

Results: Intention-to-treat analyses revealed statistically significant pre-post improvements in diurnal cortisol slope and overall life satisfaction, but not depression or self-efficacy, in the IR relative to the PTS group.

Hypnosis has proven clinical utility, yet changes in brain activity underlying the hypnotic state have not yet been fully identified. Previous research suggests that hypnosis is associated with decreased default mode network (DMN) activity and that high hypnotizability is associated with greater functional connectivity between the executive control network (ECN) and the salience network (SN). We used functional magnetic resonance imaging to investigate activity and functional connectivity among these three networks in hypnosis.

Mindfulness and meditation (MM) are increasingly used in trauma treatment, yet there is little research about therapist qualifications and clinical applications of these practices. We surveyed trauma therapists ( = 116) about their clinical uses, training, and personal practice of MM. Most respondents reported use of MM in trauma therapy, primarily MM-related imagery and breathing exercises and mindfulness in session or daily life.

The Dissociative Symptoms Scale (DSS) was developed to assess moderately severe levels of depersonalization, derealization, gaps in awareness or memory, and dissociative reexperiencing that would be relevant to a wide range of clinical populations. Structural analyses of data from four clinical and five nonclinical samples ( N = 1,600) yielded four factors that reflected the domains of interest and showed good fit with the data. Sample scores were consistent with expectations and showed very good internal consistency and temporal stability.

We explored the significance of religious faith/coping and spirituality and existential considerations reported during hospitalisation on depressive symptoms at 6-month follow-up and addressed patients' perceived influence of their faith among 97 consecutive acute coronary syndrome patients (72.2% male patients; mean age, 60.6 years) in a secular society.

This pilot study examined the effects of a manualized meditation intervention (called Inner Resources) for posttraumatic stress disorder (PTSD), depression, and anxiety symptoms among 20 African American and Caucasian mental health workers in New Orleans beginning 10 weeks after Hurricane Katrina. They participated in a 4-hour workshop followed by an 8-week home study program. Complete follow-up data were available for 15 participants.

This randomized pilot study investigated the effects of meditation with yoga (and psychoeducation) versus group therapy with hypnosis (and psychoeducation) versus psychoeducation alone on diagnostic status and symptom levels among 46 individuals with long-term depressive disorders. Results indicate that significantly more meditation group participants experienced a remission than did controls at 9-month follow-up. Eight hypnosis group participants also experienced a remission, but the difference from controls was not statistically significant.

Although many studies have shown that stronger ethnic identity is associated with better adjustment, the role of ethnic identity in the context of race-related threat is unclear. The purpose of this study was to examine the effect of ethnic identity on the severity of posttraumatic stress disorder (PTSD) symptoms in the context of race-related stress, particularly to examine whether ethnic identity moderates the effect of racism on consequent PTSD symptoms. Subjects were 91 undergraduate students (11% Caucasian, 6.

There is long-standing debate about whether elevated dissociative symptoms are common in posttraumatic stress disorder (PTSD) or whether there is a distinct subtype of cases with elevated dissociation. The current investigation examined the latent structure of dissociative symptoms in a sample of 316 male, trauma-exposed Vietnam veterans, 76 of whom were diagnosed with current PTSD. Three taxometric procedures (MAMBAC, MAXEIG, and MAXCOV) were performed on three indicator sets drawn from the Dissociative Experiences Scale.

Twelve older female dementia patient family caregivers (eight Latinas and four Caucasians) participated in a six-session manualized yoga-meditation program (called Inner Resources) designed to help caregivers cope with stress. Pre/post comparisons revealed statistically significant reductions in depression and anxiety and improvements in perceived self-efficacy. Average minutes of weekly yoga-meditation practice were significantly associated with improvements in depression.

This study examined the chronicity of PTSD in 530 male and female Vietnam veterans who were drawn from 2 large, ethnically diverse samples. Delayed onset was common, as was a failure to fully remit: 78% of the 239 veterans with full or partial lifetime PTSD were symptomatic in the 3 months prior to assessment. Cluster analysis identified 4 subtypes of posttraumatic response, with women most likely to be in a delayed onset cluster, and minority men most likely to be in a severe chronic cluster.
