Complexity of childhood sexual abuse: predictors of current post-traumatic stress disorder, mood disorders, substance use, and sexual risk behavior among adult men who have sex with men

Men who have sex with men (MSM) are the group most at risk for HIV and represent the majority of new infections in the United States. Rates of childhood sexual abuse (CSA) among MSM have been estimated as high as 46 %. CSA is associated with increased risk of HIV and greater likelihood of HIV sexual risk behavior. The purpose of this study was to identify the relationships between CSA complexity indicators and mental health, substance use, sexually transmitted infections, and HIV sexual risk among MSM. MSM with CSA histories (n = 162) who were screened for an HIV prevention efficacy trial completed comprehensive psychosocial assessments. Five indicators of complex CSA experiences were created: CSA by family member, CSA with penetration, CSA with physical injury, CSA with intense fear, and first CSA in adolescence. Adjusted regression models were used to identify relationships between CSA complexity and outcomes. Participants reporting CSA by family member were at 2.6 odds of current alcohol use disorder (OR 2.64: CI 1.24–5.63), two times higher odds of substance use disorder (OR 2.1: CI 1.02–2.36), and 2.7 times higher odds of reporting an STI in the past year (OR 2.7: CI 1.04–7.1). CSA with penetration was associated with increased likelihood of current PTSD (OR 3.17: CI 1.56–6.43), recent HIV sexual risk behavior (OR 2.7: CI 1.16–6.36), and a greater number of casual sexual partners (p = 0.02). Both CSA with Physical Injury (OR 4.05: CI 1.9–8.7) and CSA with Intense Fear (OR 5.16: CI 2.5–10.7) were related to increased odds for current PTSD. First CSA in adolescence was related to increased odds of major depressive disorder. These findings suggest that CSA, with one or more complexities, creates patterns of vulnerabilities for MSM, including post-traumatic stress disorder, substance use, and sexual risk taking, and suggests the need for detailed assessment of CSA and the development of integrated HIV prevention programs that address mental health and substance use comorbidities.This study was supported by a Grant from the NIMH (R01 MH095624) PI: O'Cleirigh; Author time (Safren) was supported, in part, by Grant 5K24MH094214.

Interdisciplinary Transgender Veteran Care: Development of a Core Curriculum for VHA Providers

Purpose: The Veteran\u27s Health Administration (VHA) has created a training program for interdisciplinary teams of providers on the unique treatment needs of transgender veterans. An overview of this program\u27s structure and content is described along with an evaluation of each session and the program overall. Methods: A specialty care team delivered 14 didactic courses supplemented with case consultation twice per month over the course of 7 months through video teleconferencing to 16 teams of learners. Each team, consisting of at least one mental health provider (e.g., social worker, psychologist, or psychiatrist) and one medical provider (e.g., physician, nurse, physician assistant, advanced practice nurse, or pharmacist), received training and consultation on transgender veteran care. Results: In the first three waves of learners, 111 providers across a variety of disciplines attended the sessions and received training. Didactic topics included hormone therapy initiation and adjustments, primary care issues, advocacy within the system, and psychotherapy issues. Responses were provided to 39 veteran-specific consult questions to augment learning. Learners reported an increase in knowledge plus an increase in team cohesion and functioning. As a result, learners anticipated treating more transgender veterans in the future. Conclusion: VHA providers are learning about the unique healthcare needs of transgender veterans and benefitting from the training opportunity offered through the Transgender Specialty Care Access Network-Extension of Community Healthcare Outcomes program. The success of this program in training interdisciplinary teams of providers suggests that it might serve as a model for other large healthcare systems. In addition, it provides a path forward for individual learners (both within VHA and in the community) who wish to increase their knowledge

The effects of suppressing trauma-related thoughts on women with rape-related posttraumatic stress disorder

A hallmark symptom of posttraumatic stress disorder (PTSD) is the presence of intrusive thoughts that come to mind against an individual\u27s will and are frequently accompanied by considerable distress. This investigation examined the effects of deliberate suppression of rape-related thoughts on female sexual assault survivors, in order to explore this facet of PTSD. Seventeen women with chronic PTSD following a sexual assault were contrasted with nineteen survivors without PTSD, using a thought suppression paradigm (e.g. [ Paradoxical effects of thought suppression. Journal of Personality and Social Psychology, 53 5-13]). Results indicated that PTSD participants experienced a rebound in the frequency of rape-related thoughts following deliberate suppression, whereas non-PTSD participants did not experience a rebound. Reported level of perceived controllability over rape-related thoughts for the PTSD participants was significantly lower during the suppression phase (as compared with the expression phase) relative to the non-PTSD participants. PTSD participants were significantly more anxious, depressed and distressed throughout the procedure relative to non-PTSD participants, although mood changes did not parallel the rebound effect found with rape-related thoughts in the PTSD group. Results are discussed in light of the role that intrusive thoughts may play in the maintenance of PTSD. Copyright (C) 1998 Elsevier Science Ltd

The role of thought suppression in posttraumatic stress disorder

Thirty motor vehicle accident (MVA) survivors with PTSD and 25 without PTSD completed a trauma-related thought-suppression task. Both groups successfully suppressed trauma-related thoughts, followed by a rebound effect for the PTSD group, and no rebound effect for the no-PTSD group, in a replication of previous work (Shipherd & Beck, 1999). Additionally, a personally relevant, neutral thought-suppression task was included to examine the generalizability of thought suppression in PTSD participants. The PTSD group was able to suppress neutral thoughts without a rebound effect, suggesting that increases in suppressed thoughts are specific to trauma-relevant cognitions in individuals with PTSD. The potential role of thought suppression as a maintaining factor for reexperiencing symptoms of PTSD is discussed. © 2005 the Association for Advancement of Behavior Therapy. All rights reserved

Repeated exposure to interoceptive cues: Does habituation of fear occur in panic disorder patients? A preliminary report

In order to explore the mechanism of action of interoceptive exposure, 12 Panic Disorder (PD) patients were presented with two sessions of repeated CO2 inhalation. Two distinct patterns of responding were noted. The first pattern was described as habituation of fear (n= 6). These patients showed decrements in pre- and post-inhalation anxiety during both sessions (with more rapid decline during session 2), as well as spontaneous recovery of fear at the onset of session 2. The second pattern indicated fear sensitization. These patients showed relatively low levels of anticipatory anxiety preceding CO2 inhalation during both sessions but reported robust increases in fear following gas inhalation. The extent of this increase was slightly less during session 2 relative to session 1 and did not appear to be mediated by cardiovascular arousal, as both groups showed rapid HR habituation during both sessions. Results are discussed in light of current theories of PD and its treatment

Response patterns to repeated CO2 inhalation in individuals with high anxiety sensitivity

The present report extends previous work which has documented two distinct response patterns to repeated presentation of interoceptive cues (using CO2 inhalation) in PD patients [Beck, J. G. and Shipherd, J. C. (1997). Repeated exposure to interoceptive cues: does habituation of fear occur in panic disorder patients? Behaviour Research and Therapy, 35, 551-557]. We were interested in determining if these two patterns of fear habituation and sensitization would be noted in panic-naive individuals who reported high levels of Anxiety Sensitivity. A second aspect of this report examined whether attention to bodily sensations versus to neutral material would impact fear habituation and sensitization.Participants included 43 panic-naive individuals who scored at least 1 standard deviation above norms on the Anxiety Sensitivity Index. Results indicated that 37% of the sample reported habituation of fear, 47% reported fear sensitization and 16% demonstrated relatively stable fear levels across 12 inhalations of CO2 during session 1. The attentional manipulation did not exert a pronounced influence on anxiety, panic symptom severity, skin conductance, or heart rate in either Habituators or Sensitizers during session 2. These results are discussed in light of their relevance in understanding fundamental psychopathological processes underlying Panic Disorder. Copyright (C) 1999 Elsevier Science Ltd

Do panic symptom profiles influence response to a hypoxic challenge in patients with panic disorder? A preliminary report

Objective: This study examined how panic symptom profiles affect response to a hypoxic laboratory challenge in patients with panic disorder. Methods: Seven patients whose naturally occurring panic attacks were characterized by prominent respiratory symptoms (Resp subgroup) were compared and contrasted with seven patients who did not report respiratory symptoms during panic attacks (NonResp subgroup). All were administered a novel 12% O2 challenge and assessed with measures of tidal volume, respiratory rate, end-tidal CO2, anxiety, and panic symptoms. Results: Although the Resp and NonResp subgroups showed equivalent increases in anxiety and panic symptoms, the Resp subgroup showed greater fluctuation in tidal volume during and after the challenge as well as overall lower levels of end-tidal CO2. Conclusions: Our results suggest the importance of panic symptom profiles in determining respiratory responses to a hypoxic challenge in patients with panic disorder. These findings are discussed in light of current theories of panic disorder, with particular attention to respiratory disturbances in this disorder

PTSD and Emotional Distress Symptoms Measured after a Motor Vehicle Accident: Relationships with Pain Coping Profiles

This study explored differences among pain patients classified as Dysfunctional, Interpersonally Distressed, and Adaptive Copers on the Multidimensional Pain Inventory with respect to PTSD symptomatology, anxiety, and depression. Eighty-five patients with pain complaints who had experienced a serious motor vehicle accident were classified into these three pain coping categories and assessed using clinician and self-report measures. Results indicated that patients classified as Adaptive Copers (n = 24) showed less PTSD symptomatology, anxiety, and depressed mood, relative to individuals classified as Dysfunctional (n = 36) and as Interpersonally Distressed (n = 25), who did not differ on these dimensions. Emotional responses during the accident (fear, helplessness, danger, perceived control, and certainty that one would die) did not differentiate the groups. Pain profiles contributed to the prediction of self-reported PTSD symptoms, controlling for state anxiety. These data suggest that pain patients with both Dysfunctional and Interpersonally Distressed coping profiles are at elevated risk for a range of posttrauma problems following a serious motor vehicle accident

How does interoceptive exposure for panic disorder work? An uncontrolled case study

To examine the influence of interoceptive exposure (IE) when used alone in the treatment of Panic Disorder (PD), 17 PD patients were presented with six IE sessions, using 35% CO2 as the exposure medium. The data indicate that IE alone is effective in reducing panic, panic-related fears, and general anxiety. However, the positive effects of IE do not appear to extend to agoraphobia, related fears, or depressed mood. Two distinct within-session patterns of fear response to IE were noted, one indicating habituation and the other indicating a lack of fear reduction. Although both patterns were associated with reductions in panic and anxiety following IE, the Habituators appeared to have a more positive outcome, which occurred more rapidly. These data suggest that IE may operate via two different pathways. Implications for understanding fear reduction are discussed, along with directions for future study. © 1997 Elsevier Science Ltd
