The current study examined whether parent psychological resources (parenting stress, depression, and social support from friends and family) moderated the effects of early family preventive intervention on parenting among high-risk families. Ninety-two preschool-age children (M age = 3.94 years) at familial risk for conduct problems participated in a randomized controlled trial of a family intervention to prevent conduct problems. The majority of families were African American or Latino and experienced multiple stressors associated with poverty and familial antisocial behavior. Families were randomized to a 22-session group-based intervention or to a no-intervention, assessment-only control condition. Parents reported on their psychological resources (parenting stress, depression and social support from friends and family) at baseline. Parenting (responsive, harsh, stimulation for learning) was assessed through self-report and observational measures four times over 24 months. Previously-reported intervention effects on responsive parenting and stimulation for learning were moderated by depression and social support from friends, respectively, such that benefits were concentrated among those at greatest risk (i.e., depressed, limited support from friends). The intervention effect on harsh parenting was not moderated by any of the parent psychological resources examined, such that parents with high and low resources benefited comparably. Consideration of moderators of preventive intervention effects on parenting provides important information about intervention impact among families experiencing multiple barriers to engagement and effective parenting. Findings suggest that parents with diminished psychological resources are just as likely to benefit. Family-focused, group-based intervention is promising for strengthening parenting among the highest risk families.

Abstract Objectives: Rates of powder cocaine and crack use have fluctuated among adolescents over recent decades. Little attention has been paid to recent trends, particularly regarding differences between users of powder cocaine and crack-two forms of the substance that are commonly reported together as "cocaine" use, despite having different effects and rates of adverse outcomes. Methods: We examined data from nationally representative samples of high school seniors who participated in the Monitoring the Future study during years 2005-2011 (weighted N = 65 717). Results: Many demographic and socioeconomic variables were similarly correlated with lifetime use of powder cocaine and crack. Income of >$50/week from job increased the odds for use, and income of >$50/week from sources other than a job more than doubled the odds for use. High religiosity, high parent education, identifying as black, and residing with one or two parents reduced odds for use. Hispanic students were at higher odds for use of crack and females were at lower odds for using powder cocaine. Among cocaine users, residing with one or two parents lowered odds for using both forms, and more religious students and Hispanics were at higher odds for crack-only use. Conclusions: Those interested in preventing initiation and adverse consequences of cocaine use should take into account the overlapping, yet different risk profiles of powder cocaine and crack users when developing programming. This is particularly important when considering differences in legal consequences for these pharmacologically similar forms of cocaine.

Attitudes toward drug use strongly determine whether an individual initiates use. Personal disapproval toward the use of a particular drug is strongly protective against use; however, little is known regarding how the use of one drug affects attitudes toward the use of other drugs. Since marijuana use is on the rise in the US and disapproval toward use is decreasing, research is needed to determine whether the use of marijuana or other licit or illicit drugs reduces disapproval toward the use of "harder," more potentially dangerous drugs. The Monitoring the Future study assesses a national representative sample of high school seniors in the US each year. This study investigated predictors of disapproval toward the use of powder cocaine, crack, lysergic acid diethylamide (LSD), heroin, amphetamine, and ecstasy ("Molly") in a weighted sample of 29,054 students from five cohorts (2007-2011). Results suggest that lifetime use of cigarettes and use of more than one hard drug consistently lowered odds of disapproval. In multivariable models, lifetime alcohol use did not affect odds of disapproval and lifetime marijuana use (without the use of any "harder" drugs) lowered odds of disapproval of LSD, amphetamine, and ecstasy, but not cocaine, crack, or heroin. In conclusion, marijuana use within itself is not a consistent risk factor for lower disapproval toward the use of harder drugs. Cigarette and hard drug use, however, are more consistent risk factors. As marijuana prevalence increases and policy becomes more lenient toward recreational and medicinal use, public health and policy experts need to ensure that attitudinal-related risk does not increase for the use of other drugs.

Religiosity is a protective factor against illicit drug use, but further investigation is needed to delineate which components of religiosity are protective against use. A racially diverse sample (N = 962) was surveyed about religiosity, exposure to users, and recent use of marijuana, powder cocaine, ecstasy, and nonmedical use of opioids and amphetamine. Results suggest that identifying as Agnostic increased odds of use for each of the five drugs; however, this effect disappeared when controlling for religious importance and attendance. High levels of religious attendance were protective against recent use of marijuana and cocaine, but protective effects diminished when controlling for exposure to users, which was a robust predictor of use of every drug. Religion is a protective mechanism against drug use, but this effect may diminish in light of exposure to users. Alternative preventative methods need to be directed toward individuals who are not religious or are highly exposed to users.

Cross-sectional analyses of 904 diverse men and women aged 50 years and older living with HIV in New York City were conducted to examine the unique experiences and needs of aging HIV-positive individuals. Using Minority Stress Theory and Syndemic Theory as guiding paradigms, the authors documented the mental health burdens of the sample with regard to depression, loneliness, and diminished psychological well-being and examined how multiple-minority status and HIV-related stigma explained these burdens. Mediation modeling demonstrated that the effects of minority stressors on mental health burden were mediated by HIV-related stigma. The mediation was significant for the overall sample and for the male subsample. Results suggest that to fully address the mental health burdens experienced by aging HIV-positive individuals, we must continue to address mental health burdens directly, and at the same time, look beyond the psychiatric symptoms to address the structural inequities faced by individuals based on their multiple-minority status.

Stigma can be harmful to drug users, particularly those in need of treatment. Beliefs and opinions about drug use may influence how individuals view or treat drug users, so research was needed to examine whether specific beliefs and opinions are related to stigma towards users. A sample of 531 adults was assessed to examine how stigmatization relates to specific beliefs and opinions about drug use. Eighty percent of the sample reported lifetime use of an illicit drug. While controlling for demographic characteristics, lifetime drug use and exposure to users, stigmatization towards users more than doubled the odds of reporting that addiction is a choice, and more than tripled the odds for reporting that marijuana and heroin are equally dangerous. Stigmatization, however, lowered the odds of reporting that drugs would be okay to use if legal. Individuals who stigmatize drug users may be under-educated about drug use; however, such individuals appear to be at low risk for use. Beliefs and opinions guided by misinformation may negatively affect users, so public health efforts are needed to educate individuals about drug use and addiction in an objective manner, and treat use as more of a health behavior and less of a moral behavior.

OBJECTIVE:To evaluate the impact of an early childhood, family-centered, school-based intervention on children's kindergarten academic achievement.METHODS:This was a cluster (school) randomized controlled trial with assessments from pre-kindergarten (pre-k) entry through the end of kindergarten. The setting was 10 public elementary schools with 26 pre-k classes in 2 school districts in urban disadvantaged neighborhoods serving a largely black, low-income population. Participants were 1050 black and Latino, low-income children (age 4; 88% of pre-k population) enrolled in 10 schools over 4 years. Universal intervention aimed to promote self-regulation and early learning by strengthening positive behavior support and effective behavior management at home and school, and increasing parent involvement in education. Intervention included after-school group sessions for families of pre-k students (13 2-hour sessions; co-led by pre-k teachers) and professional development for pre-k and kindergarten teachers. The outcome measures were standardized test scores of kindergarten reading, writing, and math achievement by independent evaluators masked to intervention condition (primary outcome); developmental trajectories of teacher-rated academic performance from pre-k through kindergarten (secondary outcome).RESULTS:Relative to children in control schools, children in intervention schools had higher kindergarten achievement test scores (Cohen's d = 0.18, mean difference = 2.64, SE = 0.90, P = .03) and higher teacher-rated academic performance (Cohen's d = 0.25, mean difference = 5.65, SE = 2.34, P = .01).CONCLUSIONS:Early childhood population-level intervention that enhances both home and school environments shows promise to advance academic achievement among minority children from disadvantaged, urban neighborhoods.

INTRODUCTION AND AIMS: Illicit drug use is a stigmatised behaviour; therefore, users tend to experience rejection and remain secretive about use. However, stigma-related rejection and secrecy can adversely affect those who reject abstinence. This study aimed to modify measures to assess these concepts with regard to illicit drug use and examine how they relate to use of various drugs and associated perception of public stigma. DESIGN AND METHODS: An Internet-based convenience sample (n = 700) was surveyed to pilot items modified from previous scales in order to assess these concepts with regard to drug use. As perceived rejection and secrecy are related and potentially overlapping constructs, exploratory factor analysis was conducted to examine the underlying structure of items previously used to assess these concepts. These variables were examined in relation to sociodemographic characteristics, perceived public stigma and use of various drugs (marijuana, powder cocaine, ecstasy and nonmedical use of opioids and prescription stimulants). RESULTS: After factor reduction, perceived rejection and secrecy loaded as two distinct, but related concepts. These modified measures had moderate to high internal consistency and both concepts were positively related to perceived public stigma and use of various drugs. DISCUSSION AND CONCLUSIONS: This pilot study demonstrated validity evidence for these measures and results suggest that illicit drug use and associated stigma are related to increased feelings of rejection and secrecy in users. Research is needed to examine whether stigma towards users serves as a deterrent to use because rejection and secrecy are associated with adverse psychosocial outcomes.
