Family Connections randomized controlled trial: assessing the feasibility and acceptability of an intervention with adolescents living with HIV and their caregivers in Ndola, Zambia.

Achieving the 95-95-95 UNAIDS targets requires meeting the needs of adolescents, however we lack evidenced-based approaches to improving adolescent adherence to antiretroviral therapy (ART), increasing viral suppression, and supporting general wellbeing. We developed Family Connections as a group intervention for adolescents and their adult caregivers and conducted a randomized controlled trial in Ndola, Zambia to test feasibility and acceptability. Fifty pairs (n = 100) of adolescents (15-19 years and on ART ≥ 6 months) and their caregivers were randomly assigned either to the intervention consisting of 10 group sessions over 6 months, or to a comparison group, which received the usual care. Each pair completed baseline and endline surveys, with adolescents also undergoing viral load testing. Of the 24-intervention adolescent/caregiver pairs, 88% attended at least eight group sessions. Most adolescents (96%) and all caregivers would recommend Family Connections to peers. Adolescent viral failure decreased but did not significantly differ by study group. Adolescents in the intervention group showed a greater reduction in HIV-related feelings of worthlessness and shame than the comparison group. The feasibility, acceptability, and the positive trend toward significantly reducing internalized stigma, generated by this Family Connections pilot study, contributes valuable data to support adolescent/caregiver approaches that use peer groups.

An Exploratory Examination of Client Perspectives on a Positive Memory Technique for PTSD.

Posttraumatic stress disorder (PTSD) treatments primarily address traumatic memories, despite PTSD's association with both traumatic and positive memory difficulties. Addressing this gap, we explored the perspectives of trauma-exposed individuals with mental health treatment experience on therapeutically addressing positive memories. A treatment-seeking sample from a community mental health center (n1 = 60) and a community sample from Amazon's Mechanical Turk (n2 = 123) were queried on the acceptability, feasibility, and delivery/components of a pilot positive memory technique. Results indicated interest or willingness in therapeutically discussing positive memories; most endorsed benefits were improved mood, positive thoughts, and self-esteem. Few barriers were identified (e.g., lack of evidence) compared with feasibility factors (ease/usefulness, improved satisfaction/tolerability, and engagement in PTSD treatment). Preferred treatment components included identifying/discussing positive memories, eliciting associated positive affect, and writing about the positive memory as homework. Results provide formative support for the development and integration of a positive memory technique into PTSD treatments.

Bayesian Time-Series Models in Single Case Experimental Designs: A Tutorial for Trauma Researchers.

Single-case experimental designs (SCEDs) involve obtaining repeated measures from one or a few participants before, during, and, sometimes, after treatment implementation. Because they are cost-, time-, and resource-efficient and can provide robust causal evidence for more large-scale research, SCEDs are gaining popularity in trauma treatment research. However, sophisticated techniques to analyze SCED data remain underutilized. Herein, we discuss the utility of SCED data for trauma research, provide recommendations for addressing challenges specific to SCED approaches, and introduce a tutorial for two Bayesian models-the Bayesian interrupted time-series (BITS) model and the Bayesian unknown change-point (BUCP) model-that can be used to analyze the typically small sample, autocorrelated, SCED data. Software codes are provided for the ease of guiding readers in estimating these models. Analyses of a dataset from a published article as well as a trauma-specific simulated dataset are used to illustrate the models and demonstrate the interpretation of the results. We further discuss the implications of using such small-sample data-analytic techniques for SCEDs specific to trauma research.

Invariance of the Construct of Posttraumatic Stress Disorder: A Systematic Review.

We conducted a systematic review of studies that have evaluated invariance of the construct of posttraumatic stress disorder (PTSD) to summarize their conclusions related to invariance/noninvariance and sources of noninvariance. In November 2017, we searched Pubmed, PSYCINFO, PILOTS Web of Science, CINAHL, Medline, and Psychological and Behavioral Science Collection for abstracts and articles with these inclusionary criteria: peer-reviewed, including DSM-IV or DSM-5 PTSD invariance as a main study aim, use of multigroup confirmatory factor analyses, and use of an independent PTSD instrument or module. In total, 45 articles out of 1,169 initially identified abstracts met inclusion criteria. Research assistants then followed Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines to complete a secondary search and independently extract data. Results indicated that DSM-IV dysphoric arousal and DSM-5 hybrid model factors demonstrated the most stability; sources of instability were some intrusion (distress to trauma cues), dysphoria/numbing (traumatic amnesia, foreshortened future, emotional numbness, detachment), and arousal (hypervigilance) items. The PTSD Checklist and PTSD Reaction Index were most often used to assess PTSD in studies investigating its invariance; however, these measures demonstrated partial conceptual equivalence of PTSD across subgroups. Instead, clinician-administered measures demonstrated more conceptual equivalence across subgroups. Age, gender, cultural/linguistic factors, and sample diversity had the least moderating effect on PTSD's symptom structure. Our review demonstrates the need to examine invariance of the PTSD construct following recommended guidelines for each empirical and clinical trial study to draw meaningful multigroup comparative conclusions.

Spanish Abstracts by Asociación Chilena de Estrés Traumático (ACET) Invarianza de medida en el constructo del Trastorno de Estrés Postraumático: una revisión sistemática TEPT E INVARIANZA DE MEDIDA Se realizó una revisión sistemática de los estudios que han evaluado la invariancia del constructo del trastorno de estrés postraumático (TEPT) para resumir sus conclusiones relacionadas con invariancia/no-invarianza y fuentes de no-invarianza. En noviembre de 2017, buscamos resúmenes y artículos en Pubmed, PSYCINFO, PILOTS Web of Science, CINAHL, Medline, y Psychological and Behavioral Science Collection con los siguientes criterios de inclusión: haber sido revisado por expertos, inclusión como objetivo principal del estudio de la invariancia del TEPT DSM-IV o DSM-5, el uso de análisis factorial confirmatorio multigrupo y uso de un instrumento o módulo de TEPT independiente. En total, 45 artículos de los 1,169 resúmenes identificados inicialmente cumplieron con los criterios de inclusión. Los asistentes de investigación siguieron luego las pautas de Informe de Elementos Preferidos para Revisiones y Metanálisis Sistemáticos (PRISMA en sus siglas en inglés) para completar una búsqueda secundaria y extraer datos de forma independiente. Los resultados indicaron que la activación disfórica del DSM-IV y los factores del modelo híbrido del DSM-5 demostraron mayor estabilidad, las fuentes de inestabilidad fueron algunos ítems de intrusiones (la angustia a las señales de trauma), disforia / adormecimiento (amnesia traumática, futuro cortoplacista, entumecimiento emocional, desapego), y elementos de activación (hipervigilancia). La lista de verificación de TEPT y el índice de reacción de TEPT fueron los más utilizados para evaluar el TEPT en los estudios que investigan su invariancia; sin embargo, estas medidas demostraron la equivalencia conceptual parcial de trastorno de estrés postraumático entre subgrupos. En su lugar, las medidas administradas por un médico demostraron una mayor equivalencia conceptual entre los subgrupos. Edad, género, factores culturales / lingüísticos y la diversidad de la muestra tuvieron el menor efecto moderador en las estructura de los síntomas de TEPT. Nuestra revisión demuestra la necesidad de examinar la invariancia del constructo de TEPT de acuerdo con las pautas recomendadas para los estudios empíricos y ensayos clínicos para sacar conclusiones significativas de comparaciones multigrupo.

Examination of the heterogeneity in PTSD and impulsivity facets: A latent profile analysis.

The experience of traumatizing events and resulting posttraumatic stress disorder (PTSD) symptomology relates to a range of impulsive behaviors. While both PTSD and impulsivity are heterogeneous and multidimensional constructs, no research has used person-centered approaches to examine subgroups of individuals based on these response endorsements. Hence, our study examined PTSD-impulsivity typologies and their construct validity in two samples: university students (n = 412) and community participants recruited through Amazon's MTurk (n = 346). Measures included the Stressful Life Events Screening Questionnaire (PTEs), PTSD Checklist for DSM-5 (PTSD severity), UPPS Impulsive Behavior Scale (negative urgency, lack of premeditation, lack of perseverance, sensation seeking). Dimensions of Anger Reaction Scale (anger), and the Patient Health Questionnaire-9 (depression). For both samples, results of latent profile analyses indicated a best-fitting 3-class solution: High, Moderate, and Low PTSD-Negative Urgency. Negative urgency was the most distinguishing impulsivity facet. Anger and depression severity significantly predicted membership in the more severe symptomatology classes. Thus, individuals can be meaningfully categorized into three subgroups based on PTSD and impulsivity item endorsements. We provide some preliminary evidence for a negative urgency subtype of PTSD characterized by greater depression and anger regulation difficulties; and underscore addressing emotional regulation skills for these subgroup members.

Empirically derived lifespan polytraumatization typologies: A systematic review.

CONTEXT: Polytraumatization classes based on trauma endorsement patterns relate to distinct clinical outcomes. Person-centered approaches robustly evaluate the nature, and construct validity of polytraumatization classes. OBJECTIVE: Our review examined evidence for the nature and construct validity of lifespan polytraumatization typologies. DATA SOURCES: In September 2016, we searched Pubmed, PSYCINFO, PSYC ARTICLES, Academic Search Complete, PILPTS, Web of Science, CINAHL, Medline, PsycEXTRA, and PBSC. Search terms included "latent profile," "latent class," "latent analysis," "person-centered," "polytrauma," "polyvictimization," "traumatization," "lifetime," "cooccurring," "complex," "typology," "multidimensional," "sequential," "multiple," "subtype," "(re)victimization," "cumulative," "maltreatment," "abuse," and "stressor." Inclusionary criteria included: peer-reviewed; latent class/latent profile analyses (LCA/LPA) of lifespan polytrauma classes; adult samples of size greater than 200; only trauma types as LCA/LPA indicators; mental health correlates of typologies; and individual-level trauma assessment. Of 1,397 articles, nine met inclusion criteria. DATA EXTRACTION: Following Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, research assistants completed a secondary reference search, and independently extracted data with standardized coding forms. RESULTS: Three-class (n = 5) or four-class (n = 4) solutions were found. Seven studies found a class characterized by higher trauma endorsement (high-trauma). All studies found a class characterized by lower trauma endorsement (low-trauma), and predominance of specific traumas (specific-trauma; e.g., childhood maltreatment). High-trauma versus low-trauma classes and specific-trauma versus low-trauma classes differed on mental health correlates. CONCLUSION: Evidence supports the prevalence of a high-trauma class experiencing poorer mental health, and the detrimental impact of aggregated interpersonal and other traumas. We highlight the clinical importance of addressing polytraumatization classes, and comprehensively assessing the impact of all traumas.

Food insecurity, sexual risk behavior, and adherence to antiretroviral therapy among women living with HIV: A systematic review.

Gender inequalities shape the experience of food insecurity among women living with HIV (WLHIV). We systematically reviewed the impact of food insecurity on sexual risk behaviors and antiretroviral therapy (ART) adherence among WLHIV. We included qualitative or quantitative peer-reviewed articles, extracted data in duplicate, and assessed rigor. Seven studies, from sub-Saharan Africa, North America, and Europe, met inclusion criteria. Food insecurity was associated with increased sexual risk through transactional sex and inability to negotiate safer sex. Hunger and food insecurity were barriers to ART initiation/adherence. Multidimensional programming and policies should simultaneously address poverty, gender inequality, food insecurity, and HIV.

Ageing and healthy sexuality among women living with HIV.

Populations around the world are rapidly ageing and effective treatment for HIV means women living with HIV (WLHIV) can live longer, healthier lives. HIV testing and screening programmes and safer sex initiatives often exclude older sexually active WLHIV. Systematically reviewing the literature to inform World Health Organization guidelines on the sexual and reproductive health and rights (SRHR) of WLHIV, identified four studies examining healthy sexuality among older WLHIV. In Uganda, WLHIV reported lower rates of sexual activity and rated sex as less important than men. In the United States, HIV stigma, disclosure, and body image concerns, among other issues, were described as inhibiting relationship formation and safer sexual practices. Sexual activity declined similarly over time for all women, including for WLHIV who reported more protected sex, while a significant minority of WLHIV reported unprotected sex. A single intervention, the "ROADMAP" intervention, demonstrated significant increases in HIV knowledge and decreases in HIV stigma and high risk sexual behaviour. WLHIV face ageist discrimination and other barriers to remaining sexually active and maintaining healthy sexual relationships, including challenges procuring condoms and seeking advice on safe sex practices, reduced ability to negotiate safer sex, physical and social changes associated with menopause, and sexual health challenges due to disability and comorbidities. Normative guidance does not adequately address the SRHR of older WLHIV, and while this systematic review highlights the paucity of data, it also calls for additional research and attention to this important area.

Longitudinal relationships among posttraumatic stress disorder symptom clusters in response to positive memory processing.

BACKGROUND AND OBJECTIVES: Avoidance, inherent to posttraumatic stress disorder (PTSD) symptomatology, is theoretically and empirically linked to the maintenance of PTSD symptom severity. While research indicates traumatized individuals avoid positive and trauma memories, several PTSD treatments focus exclusively on traumatic memories. We examined the mediating role of PTSD's avoidance in the relationship between processing positive memories and PTSD cluster severity (intrusion, mood/cognitions, arousal). METHODS: Sixty-five trauma-exposed college students (Mage = 22.52; 86.10% female) were randomly assigned to 3 conditions: narrating/processing, writing/processing, or control (same task across baseline [T0] and follow-up [T1]). RESULTS: Half-longitudinal mediation models indicated participation in the narrating vs. writing and control conditions predicted decreases in T1 intrusion severity via reduction in T1 avoidance severity. Similarly, participation in the narrating vs. writing and control conditions predicted decreases in T1 mood/cognitions' severity via reduction in T1 avoidance severity. Participation in the narrating vs. writing condition predicted decreases in T1 arousal severity via reduction in T1 avoidance severity. LIMITATIONS: Data was obtained from an analogue small-size sample of university students. In addition, sessions were only 6-8 days apart, with the processing component of each session lasting ∼30 min. CONCLUSIONS: Processing positive memories may relate to lower PTSD severity via a reduction in PTSD's avoidance, paralleling effects of processing trauma memories. Our findings support future investigations of the mechanisms underlying impacts of positive memory processing in the context of PTSD treatments.

A pilot study examining roles of cognitions and affect between positive memory processing and posttraumatic stress disorder symptom severity.

Objective: Posttraumatic stress disorder (PTSD) symptoms may impact cognitive processes underlying encoding and retrieval of positive memories. Contractor and colleagues thus proposed a Positive Memory-PTSD model outlining hypothesized pathways (e.g., improved cognitions and affect) linking active processing of positive memories and PTSD symptoms. In the current study, we empirically explored direct and indirect pathways of the Positive Memory-PTSD model including relations between presence/types of processing memory methodology, posttrauma maladaptive cognitions, positive/negative affect, and PTSD symptom severity. Methods: We randomly assigned 65 students reporting trauma histories to time-matched narrating (identifying and sharing details of elicited positive memories), writing (identifying and writing details of elicited positive memories), or control conditions. Participants completed self-report measures (T0) and repeated their assigned task condition and self-report measures 6-8 days later (T1). Results: Half-longitudinal models demonstrated direct associations of (1) being in the narrating versus other conditions with decreases in posttrauma maladaptive cognitions and negative affect, and increases in positive affect; and (2) increases in posttrauma maladaptive cognitions and negative affect with greater PTSD symptom severity. Although, when controlling for posttrauma maladaptive cognitions and negative/positive affect, being in the narrating versus other conditions was associated with decreases in PTSD symptom severity, these constructs did not explain examined relations. Conclusions: Results suggest beneficial impacts of narrating positive memories on PTSD symptom severity (accounting for cognitions/affect) and improved cognitions/affect, and a need to examine moderating variables (e.g., emotion regulation) in the Positive Memory-PTSD model.

Factors Related to Positive Memory Count Among Trauma-Exposed Individuals: A Scoping Review.

To examine the existing knowledge base on trauma experiences and positive memories, we conducted a scoping review of trauma and post-trauma factors related to positive memory count. In July 2019, we searched PubMed, Medline, PsycINFO, Web of Science, Cumulative Index of Nursing and Allied Health Literature, Embase, and PTSDpubs for a combination of words related to "positive memories/experiences," "trauma/posttraumatic stress disorder (PTSD)," and "number/retrieval." Twenty-one articles met inclusion criteria (adult samples, original articles in English, peer-reviewed, included trauma-exposed group or variable of trauma exposure, trauma exposure examined with a trauma measure/methodology, assessed positive memory count, empirical experimental/non-experimental study designs). Following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews guidelines, two authors reviewed abstracts, completed a secondary search, and independently extracted data. Our review indicated (1) that depression and PTSD were most researched; (2) no conclusive relationships of positive memory count with several psychopathology (depression, acute stress disorder, eating disorder, and anxiety), cognitive/affective, neurobiological, and demographic factors; (3) trends of potential relationships of positive memory count with PTSD and childhood interpersonal traumas (e.g., sexual and physical abuse); and (4) lower positive memory specificity as a potential counterpart to greater overgeneral positive memory bias. Given variations in sample characteristics and methodology as well as the limited longitudinal research, conclusions are tentative and worthy of further investigations.

Latent Class Analysis Offers Insight into the Complex Food Environments of Native American Communities: Findings from the Randomly Selected OPREVENT2 Trial Baseline Sample.

Native Americans (NAs) experience a high burden of obesity and diabetes, yet previous research has not holistically described the unique food environments of NA communities. The objective of this paper is to describe the subgroups and demographic characteristics related to NA household food environments. Surveys collected food getting, food assistance, and sociodemographic variables from randomly selected adults from three NA communities (n = 300) in the Midwest and Southwest. Exploratory latent class analysis (LCA) identified the appropriate number of subgroups based on indicator responses. After assigning participants to classes, demographic differences were examined using bivariate analyses. NA household food environments could be described using two subgroups ("lower" and "higher access household food environments"). The "lower access" group had significantly higher age, smaller household size, and fewer children per household than the "higher access" group, while body mass index (BMI) did not significantly vary. This is the first LCA of NA household food environments and highlights the need for approaches that characterize the complexity of these environments. Findings demonstrate that NA household food environments can be described by developing subgroups based on patterns of market and traditional food getting, and food assistance utilization. Understanding NA household food environments could identify tailored individual and community-level approaches to promoting healthy eating for NA Nations.

PTSD's factor structure and measurement invariance across subgroups with differing count of trauma types.

To investigate the effect of the count of traumatizing event (TE) types on post-trauma mental health, several studies have compared posttraumatic stress disorder (PTSD) severity between individuals experiencing one versus multiple TE types. However, the validity of these studies depends on the establishment of measurement invariance of the construct(s) of interest. The current study examined the stability of the most optimal PTSD Model symptom cluster constructs (assessed by the PTSD Checklist for DSM-5 [PCL-5]) across subgroups experiencing one versus multiple TE types. The sample included university students (n = 556) endorsing at least one TE (Stressful Life Events Screening Questionnaire). Using data from the entire sample, results suggest that the PCL-5-assessed Hybrid Model provided a significantly better fit compared to other models. Results also indicated invariance of factor loadings (metric), and intercepts (scalar) for the PCL-5-assessed Hybrid Model factors across subgroups endorsing one (n = 191) versus multiple TE types (n = 365). Our findings thus support the stability, applicability, and meaningful comparison of the PCL-assessed Hybrid Model factor structure (including subscale severity scores) across subgroups experiencing one versus multiple TE types.

Posttraumatic stress disorder and positive memories: Clinical considerations.

Encoding and retrieval difficulties, and avoidance of both traumatic and positive memories, are associated with posttraumatic stress disorder (PTSD) symptoms. However, most PTSD research and clinical work has solely examined the role of traumatic memories in the maintenance/resolution of PTSD symptoms. This review provides a comprehensive discussion of the literature on positive memories and PTSD. First, we review theories and evidence on the relations between trauma, PTSD, and memory processes (particularly positive memories). Next, we propose a conceptual model that integrates evidence from experimental and positive/memory-based intervention research and highlights hypothesized mechanisms underlying the potential effectiveness of targeting positive memories in PTSD interventions. Specifically, we discuss how targeting positive memories could (1) increase positive affect and reduce negative affect, (2) correct negative cognitions, (3) increase specificity of retrieving autobiographical memories, and (4) be effectively integrated/sequenced with and enhance the effects of trauma-focused interventions. Lastly, we suggest clinical research avenues for investigating the relations between positive memories and PTSD, to possibly alter the current PTSD intervention paradigm focused only on traumatic memories. Overall, our proposed model drawing from experimental and intervention research, and outlining potential effects of targeting positive memories to reduce PTSD severity, needs further empirical investigation.

Measuring conflict management, emotional self-efficacy, and problem solving confidence in an evaluation of outdoor programs for inner-city youth in Baltimore, Maryland.

Substantial evidence supports the value of outdoor education programs for promoting healthy adolescent development, yet measurement of program outcomes often lacks rigor. Accurately assessing the impacts of programs that seek to promote positive youth development is critical for determining whether youth are benefitting as intended, identifying best practices and areas for improvement, and informing decisions about which programs to invest in. We generated brief, customized instruments for measuring three outcomes among youth participants in Baltimore City Outward Bound programs: conflict management, emotional self-efficacy, and problem solving confidence. Measures were validated through exploratory and confirmatory factor analyses of pilot-testing data from two groups of program participants. We describe our process of identifying outcomes for measurement, developing and adapting measurement instruments, and validating these instruments. The finalized measures support evaluations of outdoor education programs serving urban adolescent youth. Such evaluations enhance accountability by determining if youth are benefiting from programs as intended, and strengthen the case for investment in programs with demonstrated success.
