Background: Since the late 1990s, there has been a worldwide surge of scientific interest in the pre-psychotic phase, resulting in the introduction of several clinical tools for early detection. The predictive accuracy of these tools has been limited, motivating the need for methodological and perspectival improvements. The EASE manual supports systematic assessment of anomalous self-experience, and proposes an overall model of understanding how most psychotic experiences may be initially generated on the basis of a unifying, fundamental, pre-reflective distortion of subjectivity.

Background: In the United States, the proportion of criminal legal-involved (CLI) adults with a substance use disorder reaches 72%, and ~150,000 persons with HIV pass through a carceral setting annually, which represents 16% of the HIV-infected population nationally. Despite the high need for substance use treatment and HIV prevention services, few carceral settings successfully link CLI individuals to treatment upon release. Young adults represent 41.

Background: Youth in the child welfare system (child welfare-involved [CWI] youth) have high documented rates of mental health symptoms and experience significant disparities in mental health care services access and engagement. Adolescence is a developmental stage that confers increased likelihood of experiencing mental health symptoms and the emergence of disorders that can persist into adulthood. Despite a high documented need for evidence-based mental health services for CWI youth, coordination between child welfare and mental health service systems to increase access to care remains inadequate, and engagement in mental health services is low.

Context: With over one-third of detained girls experiencing teenage pregnancy, it is critical that the juvenile justice system better addresses the sexual and reproductive health (SRH) needs of youth. Although pregnancy attitudes and intentions (PAI) are associated with pregnancy outcomes among the general adolescent population, this relationship has not been examined among justice-involved youth.

Methods: Participants were drawn from a longitudinal study characterizing trajectories of behavioral and reproductive health and recidivism among newly justice-involved youth in a Northeast family court.

Objective: There is strong empirical evidence that a reduction of trauma cognitions lessens PTSD symptoms, but there are discrepancies, including evidence that baseline negative posttrauma cognitions are associated with more, less, or are not associated with changes in PTSD symptoms. Discrepancies may be a function of power, sample size, analytic method, or measure.

Methods: The rate of PTSD symptoms change across 16 trauma-focused treatment sessions in a community clinic ( = 56) was estimated using a Bayesian mixed-effects model with repeated measures nested within participants.

Aim: Research has shown that preventative intervention in individuals at ultra-high risk of psychosis (UHR) improves symptomatic and functional outcomes. The staged treatment in early psychosis (STEP) trial aims to determine the most effective type, timing and sequence of interventions in the UHR population by sequentially studying the effectiveness of (1) support and problem solving, (2) cognitive-behavioural case management and (3) antidepressant medication with an embedded fast-fail option of (4) omega-3 fatty acids or low-dose antipsychotic medication. This paper presents the recruitment flow and baseline clinical characteristics of the sample.

Background: Girls have unique developmental pathways to substance use and justice system involvement, warranting gender-responsive intervention. We tested the efficacy of VOICES (a 12-session, weekly trauma-informed, gender-responsive substance use intervention) in reducing substance use and HIV/STI risk behaviors among justice- and school-referred girls.

Methods: Participants were 113 girls (M = 15.

This mixed-methods, exploratory study examined why women living with HIV (WLHIV) stay in intimate partner violence (IPV) relationships and what helps end IPV in their lives. WLHIV (n = 108) who experienced IPV and were patients at two HIV primary care clinics in San Francisco completed quantitative surveys; 15 participants also completed a qualitative interview. Qualitative data showed HIV stigma was the most cited reason for staying in an IPV relationship, followed by substance use, and then by themes of attachment insecurity.

Individuals who experience female-perpetrated sexual assault (FPSA) are underrepresented in the sexual victimization literature. Much of the existing research on FPSA centers on child welfare-involved families and convicted or incarcerated female sexual offenders, with limited research devoted to victims of FPSA. The current study included a diverse sample of 138 community adults who experienced one or more incident of FPSA, and sought to (a) describe individuals who experienced FPSA, including their overall trauma exposure, (b) describe perpetrator age and relationship to the respondent, (c) explore whether respondents labeled FPSA as sexual assault and disclosed it to others, and (d) examine the prevalence of depressive and posttraumatic symptoms in this population.

Background: HIV infection is more prevalent among people with severe mental illness (SMI) than in the general population. People with SMI may lack access to recommended antiretroviral therapy (ART), and inpatient psychiatric admissions may be opportunities to ensure that individuals receive recommended treatment.

Objective: To evaluate ART prescription patterns on an inpatient psychiatry service.

There is increasing recognition of the value of consumer participation in advocacy and community activism. Among trauma survivors, finding a sense of purpose and a way to make meaning from the trauma experience has been termed "survivor mission," and may include a call to social action, involvement in social justice activities, or public speaking. The current study describes the development of a trauma-informed trauma-survivor speakers' bureau (CHATT) and presents quantitative and qualitative outcome findings.

Women who experience housing instability are at high risk for violence and have disproportionately high rates of emergency department (ED) use. However, little has been done to characterize the violence they experience, or to understand how it may be related to ED use. We recruited homeless and unstably housed women from San Francisco shelters, free meal programs, and single room occupancy (SRO) hotels.

Background: Trauma-informed health care for women living with human immunodeficiency virus (HIV) attends not only to HIV treatment, but also to the many common physical and emotional health consequences of trauma. One principle of providing trauma-informed care is the acknowledgement that working with a population that has experienced extensive trauma affects the team members who care for them in the clinic, as well as the interactions between those team members.

Methods: To understand the needs of one primary health care team, we conducted in-depth interviews with 21 providers, staff, and collaborators who provide care to patients within the clinic.
