A multi-level modeling approach examining PTSD symptom reduction during prolonged exposure therapy: moderating effects of number of trauma types experienced, having an HIV-related index trauma, and years since HIV diagnosis among HIV-positive adults.

People living with HIV (PLWH) have extensive interpersonal trauma histories and higher rates of posttraumatic stress disorder (PTSD) than the general population. Prolonged exposure (PE) therapy is efficacious in reducing PTSD across a variety of trauma samples; however, research has not examined factors that influence how PTSD symptoms change during PE for PLWH. Using multi-level modeling, we examined the potential moderating effect of number of previous trauma types experienced, whether the index trauma was HIV-related or not, and years since HIV diagnosis on PTSD symptom reduction during a 10-session PE protocol in a sample of 51 PLWH. In general, PTSD symptoms decreased linearly throughout the PE sessions. Experiencing more previous types of traumatic events was associated with a slower rate of PTSD symptom change. In addition, LOCF analyses found that participants with a non-HIV-related versus HIV-related index trauma had a slower rate of change for PTSD symptoms over the course of PE. However, analyses of raw data decreased this finding to marginal. Years since HIV diagnosis did not impact PTSD symptom change. These results provide a better understanding of how to tailor PE to individual clients and aid clinicians in approximating the rate of symptom alleviation. Specifically, these findings underscore the importance of accounting for trauma history and index trauma type when implementing a treatment plan for PTSD in PLWH.

Patients' reasons for electing to undergo total knee arthroplasty impact post-operative pain severity and range of motion.

The present study examines the reasons cited by 103 patients for their electing to undergo total knee arthroplastic surgery and the relationship between these reasons and their post-operative pain and range of motion. Results suggest that individuals who describe different reasons for undergoing surgery vary in their post-operative recovery. Specifically, patients who cite pain as the reason they are undergoing surgery report greater levels of pain during the early post-operative period. In contrast, patients who describe goals of regaining mobility or a specific activity as their reason for undergoing surgery achieve a greater range of motion during early post-operative physical therapy. Individuals who express avoidance goals for undergoing total knee arthroplasty report more severe post-operative pain at 1 and 3 months following surgery compared to patients who express approach goals. Interventions targeted towards patients reporting pre-operative pain or avoidance goals may decrease subsequent post-operative pain and increase mobility.

Age moderates the relationship between source of social support and mental health in racial minority lesbian, gay, and bisexual youth.

We examined the relationship between source of social support and mental health (and the moderating impact of age) in 64 low socioeconomic status, racial minority lesbian, gay, and bisexual adolescents/young adults. Social support from family ( ß = -.302, p = .03; ß = -.364, p = .008), but not friends or significant others, was independently related to posttraumatic stress disorder and depression symptoms, respectively. Family social support was associated with lower posttraumatic stress disorder and depression symptoms in participants aged 16-19 years, while friend social support was associated with lower symptoms for participants aged over 20 years. Friend social support was also associated with lower posttraumatic stress disorder symptoms in participants aged 16-17 years. Interventions should target age-appropriate sources of social support.

PTSD, Depression, and Substance Use in Relation to Suicidality Risk among Traumatized Minority Lesbian, Gay, and Bisexual Youth.

Youths who are lesbian, gay, or bisexual (LGB) are more likely than heterosexuals to commit suicide. Substance use, PTSD, and depression are independent risk factors for suicidality; however, the extent to which these factors interact to predict suicidality is unclear. The current study examined the association between substance use, PTSD symptoms (PTSS), depressive symptoms, and suicidality in a sample of 68 traumatized minority LGB youths. Participants were recruited from an LGBT community center and completed a packet of questionnaires. Substance use and depressive symptoms were positively associated with prior suicide attempts. A significant three-way interaction revealed that substance use interacted with both PTSS and depressive symptoms to increase the odds of attempted suicide. Results underscore the importance of integrating substance use components into PTSD/depression treatment to reduce suicide risk in LGB youth.

The impact of HIV diagnosis-related vs. non-diagnosis related trauma on PTSD, depression, medication adherence, and HIV disease markers.

The present study examined differences in three groups of people living with HIV (PLWH); those who did not meet post-traumatic stress disorder (PTSD) criteria, those with HIV-related PTSD, and those with non-HIV-related PTSD. Patients with PTSD reported more PTSD and depression symptoms and lower levels of medication adherence. Participants with HIV-related PTSD were more likely to report reliving the trauma and were more adherent to HIV medications than participants with non-HIV-related PTSD. Results suggest that HIV- and non-HIV-related PTSD have a similar impact on PLWH and in both cases impact their functioning, adherence to medications, and levels of depression.

Relationship of race-, sexual orientation-, and HIV-related discrimination with adherence to HIV treatment: a pilot study.

Adherence to highly active antiretroviral therapy (HAART) must be close to perfect in order to maintain suppression of HIV viral load, and to prevent the development of drug resistant strains of HIV. People living with HIV (PLWH) often report low levels of adherence. One variable that has been linked to poor adherence is perceived discrimination; however, research has generally not considered the possible unique effects of different types of discrimination on adherence. The present pilot study aimed to examine the association of three types of discrimination (due to HIV+ status, race, or sexual orientation) with adherence among 57 PLWH. Logistic regression analyses were conducted to demonstrate the relationships between each type of discrimination and self-reported adherence. Racial discrimination significantly predicted lower adherence levels, whereas sexual orientation- and HIV-related discrimination did not. Results underscore the importance of addressing discrimination issues, specifically racial, when designing interventions to improve adherence to HAART.

Emotional support and affect: associations with health behaviors and active coping efforts in men living with HIV.

The present study represents a cross-sectional examination of the relationship between affect, social support and illness adjustment in men diagnosed with HIV/AIDS. Positive and negative affect were examined as separate mediators of the relationship between emotional support received from a primary support provider and illness adjustment in 105 men living with HIV. Results suggested that depressive symptoms emerged as a mediator between emotional support and engaging in healthy lifestyle behaviors (assessed by summary index). In contrast, positive affect emerged as the primary mediator between emotional support and greater amounts of active coping. Overall, findings suggested that emotional support from close others was indirectly associated with health behaviors and coping through recipients' affective states, and that these positive and negative affective states had differential relationships with multiple aspects of illness adjustment in men living with HIV.

Polysomnographically measured sleep abnormalities in PTSD: a meta-analytic review.

Although sleep complaints are common among patients with Posttraumatic stress disorder (PTSD), polysomnographic studies examining sleep abnormalities in PTSD have produced inconsistent results. To clarify discrepant findings, we conducted a meta-analytic review of 20 polysomnographic studies comparing sleep in people with and without PTSD. Results showed that PTSD patients had more stage 1 sleep, less slow wave sleep, and greater rapid-eye-movement density compared to people without PTSD. We also conducted exploratory analyses aimed at examining potential moderating variables (age, sex, and comorbid depression and substance use disorders). Overall, studies with a greater proportion of male participants or a low rate of comorbid depression tended to find more PTSD-related sleep disturbances. These findings suggest that sleep abnormalities exist in PTSD, and that some of the inconsistencies in prior findings may be explained by moderating variables.

The differential impact of PTSD and depression on HIV disease markers and adherence to HAART in people living with HIV.

Despite high rates of comorbidity, research has typically focused on the independent impact of posttraumatic stress disorder (PTSD) and depression symptoms in people living with HIV (PLWH). The present study examined the independent and comorbid influence of PTSD and depression symptoms on medication adherence, CD4 cell counts, and viral load, over the course of 3 months in 57 PLWH (82% men, 54% Caucasian, 44% African American) recruited from a clinic or social service agency. Both PTSD and depressive symptoms predicted lower subsequent adherence. However, only depressive symptoms predicted lower CD4 counts and presence of a detectable viral load. Participants reporting symptoms consistent with diagnostic levels of comorbid PTSD and depression were less likely to adhere to HAART and were more likely to have a detectable viral load. These results highlight the influences of PTSD and depression on adherence and HIV disease markers, and underscore the importance of examining comorbid symptomatology in PLWH.
