Effects of cognitive-behavioural therapy on anxiety,depression and condom use in people with HIV in Mexico City: a pilot study

Anxiety and depression in people living with HIV (PLWH) are negatively associated with healthy sexual behaviours. We pilot-tested a Cognitive-Behavioural Therapy (CBT)-based intervention to reduce anxiety and depression, aimed to increase serostatus disclosure to sexual partners, quality of sexual life (QoSL) and condom use. The study had a single-case experimental design (AB) with follow-up measures. Eleven PLWH with moderate/severe anxiety/depression received six-module CBT intervention delivered in ten one-hour individual weekly sessions. Anxiety, depression, consistent/correct condom use and QoSL were measured. Depression and anxiety decreased after the intervention (depression baseline [BL] Mdn = 21, final [F] Mdn = 3, z = -2.934, p = .003; anxiety BL Mdn = 30, F Mdn = 4, z = -2.941, p = .003). QoSL improved (BL Mdn = 28, F Mdn = 13, z = -2.625, p = .009), along with participants’ ability to use condoms (57.14 vs.100, z = -2.937, p = .003). Effect size was large, changes were maintained at follow-up measurements. The CBT intervention had positive effects in reducing anxiety and depression, which could facilitate the acquisition of healthy sexual behaviours. Further studies are important to clarify the benefits of targeting emotional variables to improve wellbeing and prevention behaviours in PLWH.     

Alcohol use among adults in Kenya: Results from the National Non-Communicable Diseases Risk Factor survey, 2015

The aim of this study was to assess the prevalence and correlates of alcohol use among Kenyan adults. We analysed data from the Kenya cross-sectional national Non-Communicable Diseases Risk Factor survey, 2015. The survey sampled 4 469 adults (median age 38.0 years, interquartile range = 23, age range of 18–69 years). Results indicate that 6.7% were hazardous or harmful alcohol users and 12.8% past month binge-drinkers. In adjusted logistic regression analysis, being male, middle aged, belonging to the Luhya or Kalenjin ethic group, tobacco use, and having hypertension increased the odds for hazardous or harmful alcohol use. Socio-demographic and health factors appear to influence risk for hazardous or harmful alcohol use among adults in Kenya.     

Covenant,blood, and violence: America at war with itself and others

Religious nationalism is dangerous, because it tends toward violence. In the case of America, religious nationalism is preceded by, and dependent upon, a covenant with God that renders judgment against the nation when it fails to embody divine justice. The second use of the law in Lutheran theology, combined with René Girard's scapegoat theory, provides the prophetic public theologian with a searchlight to make visible the nation's justification of violence. The haunting question becomes this: should the prophetic public theologian expose the lie on which American religious nationalism is built and risk sundering human community?     

Testing the properties of the triarchic model of psychopathy in a community sample: Self‐reported trait aggression and drug consumption associations

The triarchic model of psychopathy encompasses different conceptions of psychopathic personality characterized by three phenotypic components: boldness, disinhibition, and meanness. Psychopathy is a complex construct at both emotional and behavioral level. The aim of this study was to determine the core elements of psychopathic personality in a community sample and analyze the relation between these elements and other personality traits such as aggression, and certain specific behavioral manifestations such as substance use. The study sample comprised 1,159 participants aged between 17 and 74 years, who were administered the Triarchic Psychopathy Questionnaire, the Impulsive‐Premeditated Aggression Scale, and the Aggression Questionnaire. The results show that the constructs of meanness and disinhibition are more highly associated with different forms of both impulsive and premeditated aggression. Furthermore, men scored higher on all three components of the triarchic model compared to women. Finally, higher substance use (tobacco and drugs) was associated with higher scores in meanness, boldness, and disinhibition. These findings demonstrate the importance of assessing psychopathy in a community sample, and the detection of possible risk factors for the disorder.     

Evidence‐Based Human Trafficking Policy: Opportunities to Invest in Trauma‐Informed Strategies

Human trafficking is a critical social issue characterized by chronic trauma among victims, and frequently preceded by traumatic experiences that contribute to risk of victimization. Therefore, the research‐based practice of trauma‐informed care is a highly appropriate lens for both prevention and intervention. This work examines federal legislation in the United States related to human trafficking for references to trauma, as well as how the use of research could implicitly direct public policy responses toward trauma‐informed approaches. Legislation on human trafficking has risen substantially since 1989, and the use of research and trauma language within these policies has also observed substantial increases. While the use of trauma language was associated with limited progression in the policy process, legislation using research language was more likely to pass out of Committee and become enacted. Moreover, legislation may leverage research in ways that have the potential to bolster trauma‐informed practice among human trafficking victims. Specifically, research can be used to describe the problem and causal mechanisms (e.g., impact of trauma), guide “best practice” for service delivery, and generate knowledge through studies and evaluations that guide future policy. Therefore, human trafficking legislation that implicitly guides trauma‐informed practice via the use of research may be particularly promising for the field.

Incremental Validity of Coping-oriented Marijuana Use Motives in the Prediction of Affect-based Psychological Vulnerability

The present investigation examined whether coping-oriented motives to use marijuana, as measured by the Marijuana Motives Measure (MMM; Simons et al. in J. Couns. Psychol. 45:265–273, 1998), were uniquely related to affect-based psychological vulnerability factors among marijuana users. Participants were 131 adult current marijuana users (72 women, M _age = 20.14, SD = 3.37 years). As hypothesized, after controlling for gender, cigarettes smoked per day, past 30-day marijuana use, total years of marijuana use, and alcohol consumption, coping motives were significantly and incrementally related to negative affect-based psychological vulnerability factors. No other marijuana use motives demonstrated a similar type of relationship to the dependent variables, providing a high degree of explanatory specificity. These data suggest that coping-oriented motives to use marijuana may be an important explanatory construct in better understanding marijuana and psychological vulnerability relations.     

Impact of a comprehensive safety program on bicycle helmet use among middle-school children

A bicycle helmet program was evaluated in three middle schools using a multiple baseline across schools design. Two of the three schools had histories of enforcement of helmet use. During baseline many students riding their bikes to and from school did not wear their helmets or wore them incorrectly. A program that consisted of peer data collection of correct helmet use, education on how to wear a bicycle helmet correctly, peer goal setting, public posting of the percentage of correct helmet use, and shared reinforcers, all of which were implemented by the school resource officer, increased afternoon helmet use and afternoon correct helmet use in all three schools. Probe data collected a distance from all three schools indicated that students did not remove their helmets once they were no longer in close proximity to the school, and probe data collected in the morning at two of the schools showed that the behavior change transferred to the morning.

A Systematic Review of the Relationship between High School Dropout and Substance Use

A systematic review of peer-reviewed, empirical literature published between 1990 and 2006 was undertaken to determine whether existing research could provide evidence, and a deeper understanding of the relationship between dropping out of high school and the use of substances such as tobacco, alcohol, cannabis/marijuana and other illicit drugs. Forty-six articles were reviewed. The review describes the heterogeneity of theoretical frameworks employed, as well as the limited ability of any one to adequately explain the relationship between high school dropout and substance use. A refinement of the many confounding and mediating variables into coherent conceptual categories would aid more robust theory building and theory integration. In spite of differences in dropout definitions and diverse measures of substance use across studies, the main findings point to a largely consistent relationship between dropping out of high school and substance use. However, socially disadvantaged and poor persons, dropouts, and drug users are over-represented in some of the loss to follow-up groups in longitudinal studies surveyed. More rigorous mechanisms to retain participants in longitudinal studies should be employed. Suggestions for future research include comparisons between urban and rural populations, employing qualitative research methods, and research in developing countries, which have the least favourable school outcomes and a dearth of research on high school dropout.
