A comparison of cognitive-processing therapy with prolonged exposure and a waiting condition for the treatment of chronic posttraumatic stress disorder in female rape victims.

The purpose of this study was to compare cognitive-processing therapy (CPT) with prolonged exposure and a minimal attention condition (MA) for the treatment of posttraumatic stress disorder (PTSD) and depression. One hundred seventy-one female rape victims were randomized into 1 of the 3 conditions, and 121 completed treatment. Participants were assessed with the Clinician-Administered PTSD Scale, the PTSD Symptom Scale, the Structured Clinical Interview for DSM–IV, the Beck Depression Inventory, and the Trauma-Related Guilt Inventory. Independent assessments were made at pretreatment, posttreatment, and 3 and 9 months posttreatment. Analyses indicated that both treatments were highly efficacious and superior to MA. The 2 therapies had similar results except that CPT produced better scores on 2 of 4 guilt subscales.

Prior interpersonal trauma: the contribution to current PTSD symptoms in female rape victims.

The purpose of the current study was to disentangle the relationship of childhood sexual abuse and childhood physical abuse from prior adult sexual and physical victimization in predicting current posttraumatic stress disorder (PTSD) symptoms in recent rape victims. The participants were a community sample of 117 adult rape victims assessed within 1 month of a recent index rape for a history of child sexual abuse, child physical abuse, other adult sexual and physical victimization, and current PTSD symptoms. Results from path analyses showed that a history of child sexual abuse seems to increase vulnerability for adult sexual and physical victimization and appears to contribute to current PTSD symptoms within the cumulative context of other adult trauma.

How Well Does Cognitive-Behavioral Therapy Treat Symptoms of Complex PTSD? An Examination of Child Sexual Abuse Survivors Within A Clinical Trial

Are brief cognitive-behavioral treatments for posttraumatic stress disorder (PTSD) also effective for the wider range of symptoms conceptualized as complex PTSD? Female rape victims, most of whom had extensive histories of trauma, were randomly assigned to cognitive-processing therapy, prolonged exposure, or a delayed-treatment waiting-list condition. After determining that both types of treatment were equally effective for treating complex PTSD symptoms, we divided the sample of 121 participants into two groups depending upon whether they had a history of child sexual abuse. Both groups improved significantly over the course of treatment with regard to PTSD, depression, and the symptoms of complex PTSD as measured by the Trauma Symptom Inventory. Improvements were maintained for at least 9 months. Although there were group main effects on the Self and Trauma factors, there were no differences between the two groups at posttreatment once pretreatment scores were covaried. These findings indicate that cognitive-behavioral therapies are effective for patients with complex trauma histories and symptoms patterns.

Sleep difficulties and alcohol use motives in female rape victims with posttraumatic stress disorder

The purpose of this study was to assess the relationship between sleep difficulties and drinking motives in female rape victims with posttraumatic stress disorder (PTSD). Seventy-four participants were assessed for PTSD symptoms, depression, sleep difficulties, and drinking motives. Results demonstrated that neither PTSD symptoms nor depression were related to any motives for using alcohol. On the other hand, after controlling for education, sleep difficulties were significantly related to drinking motives for coping with negative affect, but not pleasure enhancement or socialization. The findings suggest that sleep difficulties may be an important factor contributing to alcohol use in rape victims with PTSD.

Trauma-Related Sleep Disturbance and Self-Reported Physical Health Symptoms in Treatment-Seeking Female Rape Victims

The purpose of the study was to assess the relationship between trauma-related sleep disturbance and physical health symptoms in treatment-seeking female rape victims. A total of 167 participants were assessed for PTSD symptoms, depression, sleep disturbance, and frequency of self-reported health symptoms. Results demonstrated that trauma-related sleep disturbance predicted unique variance in physical health symptoms after other PTSD and depression symptoms were controlled. The findings suggest that trauma-related sleep disturbance is one potential factor contributing to physical health symptoms in rape victims with PTSD.

A Simple Method to Identify Sleep Apnea Using Holter Recordings

Introduction: Despite its severe cardiovascular and other consequences, sleep apnea syndrome frequently is undiagnosed. Because apneas result in repeated autonomic arousals associated with cyclic variations in heart rate (CVHR), we hypothesized that sleep apnea syndrome could be identified from simple HR tachograms (graphs of HR vs time) derived from ECG monitoring.

Pattern of Change in Prolonged Exposure and Cognitive-Processing Therapy for Female Rape Victims With Posttraumatic Stress Disorder

Curve estimation techniques were used to identify the pattern of therapeutic change in female rape victims with posttraumatic stress disorder (PTSD). Within-session data on the Posttraumatic Stress Disorder Symptom Scale were obtained, in alternate therapy sessions, on 171 women. The final sample of treatment completers included 54 prolonged exposure (PE) and 54 cognitive-processing therapy (CPT) completers. For both PE and CPT, a quadratic function provided the best fit for the total PTSD, reexperiencing, and arousal scores. However, a difference in the line of best fit was observed for the avoidance symptoms. Although a quadratic function still provided a better fit for the PE avoidance, a linear function was more parsimonious in explaining the CPT avoidance variance. Implications of the findings are discussed.

Effect of cognitive behavioral therapy on heart rate variability during REM sleep in female rape victims with PTSD.

Six female rape victims with posttraumatic stress disorder (PTSD) were assessed for sleep disturbances. Five responded to cognitive–behavioral therapy (CBT) and one did not complete treatment. Sympatho-vagal balance was measured using heart rate variability (HRV) during rapid eye movement (REM) sleep. The treatment responders significantly decreased on HRV while the noncompleter increased. The responders also significantly decreased on sleep disturbances. The noncompleter remained unchanged. Thus a remission in PTSD symptoms following CBT accompanied a reduction in the HRV indicator of sympathetic predominance in REM sleep.

PTSD and major depression: Methodological and treatment considerations in a single case design*

A case of successful cognitive behavioral treatment of a woman diagnosed with assault-related posttraumatic stress disorder (PTSD) and comorbid major depression is presented. The client was treated using a combination of stress inoculation, cognitive restructuring, and imaginal in vivo exposure. A statistical technique based on classical test theory (Yarnold, 1988) was used to evaluate the clients progress in treatment. After 18 sessions, few statistically significant improvements were noted, although visual inspection of the data suggested improvements. However, after an additional six sessions devoted solely to exposure-based treatment, dramatic improvements were observed, which were maintained at one- and three-month followups. The case highlights the utility of statistical analysis in single case designs to evaluate the clinical decisions made in the selection of target behaviors for treatment of PTSD when comorbid disorders are present.

Relations between social skills and ward behavior in chronic schizophrenia

The relationship between social skills and ward behavior among chronic schizophrenia patients was investigated. Twenty-eight inpatients participated in an unstructured role play test and were rated by staff members on a number of indices of ward behavior (e.g., social interactions, inappropriate behavior). Overall, there was a relationship between social skill on the role play and social behavior on the ward. Speech clarity was the social skill most strongly related to ward behavior, even when controlling for symptomatology. However, several other social skill variables (e.g., gaze, affect) were not related to social adjustment. The results are discussed in terms of the validity of social skill assessments in patients with chronic schizophrenia, and their implications for psychosocial treatment of this population.
