RESUMO
Knowing at antiretroviral therapy (ART) initiation which patients might be at greatest risk for failure to achieve viral suppression would enable providers to target patients most in need and tailor their care appropriately. This study involved multilevel modeling of data from a randomized controlled trial among outpatients in Seattle, WA, USA. The 224 participants initiating or switching ART at baseline were 24% female, 34% heterosexual, and 47% Caucasian. Of 24 baseline demographic and psychosocial patient-level variables modeled in separate generalized estimating equations, only employment predicted changes in HIV-1 RNA viral load or CD4 lymphocyte count over the course of the 9-month trial. Although the findings require replication, they suggest adherence support strategies should emphasize close monitoring and support for all patients initiating ART.

Greater understanding of barriers to risk reduction among incarcerated HIV+ persons reentering the community is needed to inform culturally tailored interventions. This qualitative study elicited HIV prevention-related information, motivation and behavioral skills (IMB) needs of 30 incarcerated HIV+ men and women awaiting release from state prison. Unmet information needs included risk questions about viral loads, positive sexual partners, and transmission through casual contact. Social motivational barriers to risk reduction included partner perceptions that prison release increases sexual desirability, partners' negative condom attitudes, and HIV disclosure-related fears of rejection. Personal motivational barriers included depression and strong desires for sex or substance use upon release. Behavioral skills needs included initiating safer behaviors with partners with whom condoms had not been used prior to incarceration, disclosing HIV status, and acquiring clean needles or condoms upon release. Stigma and privacy concerns were prominent prison context barriers to delivering HIV prevention services during incarceration.

Antiretroviral therapy (ART) greatly reduces morbidity and mortality for people with HIV/AIDS. However, for optimal effectiveness patients must achieve strict adherence to dosing regimens, which is difficult to maintain over the long term. Interventions to improve adherence have shown promising results, but with small effects. One explanation for small overall effects is that some patient subgroups are less able to benefit from current interventions; however, this explanation lacks empirical support. This study used multilevel modeling of data from a randomized controlled trial in an exploratory analysis to assess whether patient factors moderated the impact of peer support and pager reminders on ART adherence and biological markers of HIV. According to 272 interaction models using an alpha-corrected significance criteria, none of 34 patient characteristics significantly moderated either intervention. Findings suggest that intervention research might more profitably focus on other ways of improving effects, like individual patient needs, rather than target subgroups.

Behavioral interventions to prevent HIV or assist HIV-positive persons often incorporate peers, yet empirical support for their efficacy is only recently accumulating. We describe the results of a review of the global literature, identifying 117 studies evaluating the efficacy of peer-based interventions in the area of HIV/AIDS. About half were conducted in the developing world and half in Western nations. Across a range of populations and intervention modalities, the majority of studies provided some support for peer interventions according to outcome indicators in the domains of sexual risk behavior, attitudes and cognitions, HIV knowledge, and substance use. However, outcomes assessed using biomarkers and other non-self-report variables were less likely to indicate intervention efficacy. Overall, findings suggest that we can have some confidence in peer interventions, yet more data are needed demonstrating an effect in the most rigorous study designs and with outcomes that are not potentially affected by respondent bias.

BACKGROUND: text-messaging systems have been used to promote a range of health behaviors, including medication adherence among human immunodeficiency virus-positive individuals. However, little is currently known about the specific characteristics of messaging systems that promote user engagement. OBJECTIVE: using data from a randomized controlled trial involving a pager-based text messaging system, this study sought to examine the overall usability of the system, user evaluation of the system, demographic and psychosocial correlates of usability, and its performance as an adherence assessment tool. MATERIALS AND METHODS: the messaging system consisted of an alphanumeric pager capable of sending and receiving individualized text messages and the software necessary to program and track communication. The system was evaluated using behavioral outcomes (pager message response rate), self-report survey responses, focus group discussions, and data from electronic medication monitoring pill bottles. RESULTS: Although the majority of participants reported that the system was effective in reminding them to take medication doses, the overall response rate to system messages was relatively low (42.8%) and dropped significantly over the course of the 3-month intervention period. In addition, user engagement did not differ significantly by most demographic and psychosocial variables. CONCLUSIONS: the pager-based text messaging system was received well by participants and appears to be applicable to a broad population; however, the system did not actively engage all participants over the course of the trial. Future research should determine whether systems customized to personal preference in notification style, frequency, and user device can increase use and provide further assistance to achieve optimal medication adherence.

BACKGROUND: Because a large proportion of patients with panic attacks receiving approved pharmacotherapy do not respond or respond poorly to medication, it is important to identify additional therapeutic strategies for the management of panic symptoms. This article describes a randomized, rater-blind study comparing low-dose risperidone to standard-of-care paroxetine for the treatment of panic attacks. METHODS: Fifty six subjects with a history of panic attacks were randomized to receive either risperidone or paroxetine. The subjects were then followed for eight weeks. Outcome measures included the Panic Disorder Severity Scale (PDSS), the Hamilton Anxiety Scale (Ham-A), the Hamilton Depression Rating Scale (Ham-D), the Sheehan Panic Anxiety Scale-Patient (SPAS-P), and the Clinical Global Impression scale (CGI). RESULTS: All subjects demonstrated a reduction in both the frequency and severity of panic attacks regardless of treatment received. Statistically significant improvements in rating scale scores for both groups were identified for the PDSS, the Ham-A, the Ham-D, and the CGI. There was no difference between treatment groups in the improvement in scores on the measures PDSS, Ham-A, Ham-D, and CGI. Post hoc tests suggest that subjects receiving risperidone may have a quicker clinical response than subjects receiving paroxetine. CONCLUSION: We can identify no difference in the efficacy of paroxetine and low-dose risperidone in the treatment of panic attacks. Low-dose risperidone appears to be tolerated equally well as paroxetine. Low-dose risperidone may be an effective treatment for anxiety disorders in which panic attacks are a significant component. TRIAL REGISTRATION: ClinicalTrials.gov Identifier: NCT100457106.

Posttraumatic stress disorder (PTSD) is a risk factor for cardiovascular disease (CVD) and diabetes. Dedert and colleagues hypothesized a model whereby PTSD leads to poor health behaviors, depression, and pre-clinical disease markers, and that these factors lead to CVD and diabetes (Ann Behav Med, 2010, 61-78). This study provides a preliminary test of that model. Using data from a mailed cross-sectional survey conducted 2012-2013, path analysis was conducted among Nâ¯=â¯657 with complete demographic data. We first analyzed the hypothesized model, followed by four alternatives, to identify the best-fitting model. The alternate model that specified pathways from depression to health behaviors had the best fit. Contrary to hypotheses, higher PTSD symptoms were associated with better physical activity and diet quality. Of the specific indirect pathways from PTSD to Body Mass Index (BMI), only the path through depression was significant. Higher depression symptoms were significantly associated with less physical activity, poorer diet, and greater likelihood of smoking. In addition, the specific indirect effect from depression to BMI through physical activity was significant. Current smoking and higher BMI were associated with greater likelihood of diabetes, and hypertension was associated with greater likelihood of CVD. PTSD symptoms may increase risk for CVD and diabetes through the 'negative impact of depression on health behaviors and BMI. With or without PTSD, depression may be an important target in interventions targeting cardiovascular and metabolic diseases among veterans.
RESUMO
Alcohol dependence (AD) and posttraumatic stress disorder (PTSD) are highly comorbid, yet limited research has focused on PTSD and daily drinking as they relate to self-appraised alcohol-related problems. In treatment contexts, patients' appraisals of alcohol-related problems have implications for assessment, intervention strategies, and prognosis. This study investigated the moderating effect of within-person (daily symptoms) and between-person (overall severity) differences in PTSD on the association between daily drinking and same-day alcohol-related problems. Participants with comorbid AD and PTSD (N = 86) completed 1 week of Interactive Voice Recognition data collection, and logistic and γ-adjusted multilevel models were used to estimate odds and magnitude of self-appraised alcohol-related problems. Results revealed that both within-person and between-person PTSD moderated the association between number of drinks and severity of self-appraised problems. As within-person and between-person PTSD symptoms increased, there was a weaker association between number of drinks consumed and perceived alcohol-related problems. Contrasts further revealed that on nondrinking and light-drinking days, PTSD (both daily symptoms and overall severity) was positively associated with ratings of alcohol-related problems. However, PTSD was not associated with alcohol-related problems on heavier drinking days. In conclusion, more severe PTSD is associated with a less directly contingent relationship between drinking quantity and perceived alcohol-related problems. These findings suggest the importance of further investigations of this moderating effect as well as clinical treatment of comorbid AD and severe PTSD with functional analysis of drinking.

Functional analytic psychotherapy (FAP) is a relational approach to psychotherapy that is behavioral, yet involves an intensive, emotional, and in-depth therapy experience. FAP is approachable by therapists of diverse theoretical backgrounds owing to the minimal use of behavioral jargon, and can be used as an addition or complement to other interventions. The methods described in this article-being aware of clients' clinically relevant behaviors, being courageous in evoking clinically relevant behaviors, reinforcing improvements with therapeutic love, using behavioral interpretations to help clients generalize changes to daily life, and providing intensive and personal experiential training of FAP practitioners-maximize the impact of the therapeutic relationship to promote change and personal growth for both clients and therapists.

Peers have intervened to promote health since ancient times, yet few attempts have been made to describe theoretically their role and their interventions. After a brief overview of the history and variety of peer-based health interventions, a 4-part definition of peer interveners is presented here with a consideration of the dimensions of their involvement in health promotion. Then, a 2-step process is proposed as a means of conceptualizing peer interventions to promote health. Step 1 involves establishing a theoretical framework for the intervention's main focus (i.e., education, social support, social norms, self-efficacy, and patient advocacy), and Step 2 involves identifying a theory that justifies the use of peers and might explain their impact. As examples, the following might be referred to: theoretical perspectives from the mutual support group and self-help literature, social cognitive and social learning theories, the social support literature, social comparison theory, social network approaches, and empowerment models.

The authors review the literature relating hypnotizability and posttraumatic stress. Sixty-seven abstracts containing the key terms ASD, acute stress, trauma, traumatic, or PTSD in combination with either hypnotic susceptibility or hypnotizability were reviewed. Six articles were found containing data on hypnotizability and posttraumatic stress symptoms. Each of the studies showed some relation between hypnotizability and posttraumatic stress, but, in all of them, hypnotizability was measured after the potentially traumatizing event. High hypnotizability might be a risk factor for both acute and chronic posttraumatic symptoms. However, this cannot be determined until prospective studies measure hypnotizability in individuals before and after a potentially traumatizing event, perhaps by targeting populations that are at risk for experiencing trauma.

OBJECTIVE: To explore the concept of the negative syndrome as a dimensional entity that exists in multiple primary diagnoses, and to compare the negative syndrome in nonschizophrenic disorders and schizophrenia. BACKGROUND: Although initially considered specific to schizophrenia, the negative syndrome has subsequently been described in major depression, stroke, and dementia. METHOD: We performed an exploratory factor analysis on Positive and Negative Symptom Scale scores of 82 subjects with major depressive disorder and 76 subjects with organic brain disease (dementia or stroke). RESULTS: The examination of the resultant symptom clusters revealed that the structure of the negative syndrome in major depressive disorder and organic brain disease closely corresponded to that in schizophrenia literature. CONCLUSIONS: The negative syndrome may be a nosologic entity, which remains fairly consistent across psychotic and nonpsychotic diagnostic categories. Confirmatory studies are merited to determine the degree and strength of the similarity in structure of the negative syndrome in psychotic, affective, and cognitive illness.
