The Palestinian Youth Health Risk study investigates patterns of risk behaviours among Palestinian youth, their perceptions of the risks and benefits of such behaviours, and the relationship of exposure to violence with mental health and engagement in risk behaviours. We conducted a representative survey among 2500 individuals aged 15-24 years in the West Bank and East Jerusalem, permitting reliable comparison across sex and rural-urban divisions. A stratified 2-stage random sample was drawn from the 2007 population census, with strata formed by crossing the 12 governorates with urban, rural and refugee camp locations. Within strata, 208 survey clusters were sampled with probability proportional to size. Within each cluster, 14 households with youth of th...

Most of these cases can be cured by quick, inexpensive surgical procedures, but a shortage of trained surgeons makes it unlikely that the need for such surgeries-estimated to reach 32 million cases globally by 2020-can be met under current practices. HelpMeSee Inc. (HMS) is developing an approach to surgery training and delivery that includes use of high-fidelity simulator technology and associated curricula for high-volume training, development of a system of independent private practitioners, and training where necessary of individuals without medical degrees. RAND researchers determined that the program has the potential to scale up surgical capacity rapidly and that under optimistic assumptions, the HMS program could largely close the backlog of surgical cases in the four ...

Six hundred ninety three (45%) at baseline were diagnosed with cataracts and offered free surgery, of which 484 (73%) were operated. Difference-in-difference was used to estimate impacts of surgery, using surgery-ineligible, mostly non-cataract blind as controls. For patients, surgery resulted in a 0.31 standard deviation increase in an index of social participation (p < 0.001), a 30% proportional increase in ability to perform activities of daily living (p < 0.001), and a 17% proportional reduction in Center for Epidemiologic Studies Depression Scale (CES-D) depression score (p < 0.001).

In a sample of approximately 2,500 15-24 year old Palestinian youth, perceived engagement of general peers in alcohol consumption, drug use and sexual activity was substantially greater than youths' own (self-reported) engagement in these activities, suggesting a tendency to overestimate the prevalence of risk-taking behavior among peers. Individual participation in a risk behavior strongly covaries with the perceived levels of both friends' and peers' engagement in that behavior (p = 0.00 in each case). In addition, significant clustering of risk behaviors is found: youth who participate in one risk behavior are more likely to participate in others. These findings for a rare representative sample of Middle Eastern youth are strikingly similar to those in the US and Europe. The clustering of behaviors suggests t...

However, there is limited research on programs increasing the availability of skilled birth attendants in developing countries. We study the implementation of the Nigeria Midwives Service Scheme, a government program that recruited and deployed nearly 2,500 midwives to rural primary health care facilities across Nigeria in 2010. An outcome evaluation carried out by this team found only a modest impact on the use of antenatal care and no measurable impact on skilled birth attendance. This paper draws on perspectives of policymakers, program midwives, and community residents to understand why the program failed to have the desired impact. We conducted semi-structured interviews with federal, state and local government policy makers and with MSS midwives. We also conducted focus groups with community stakeho...

However, little research has examined whether depression alleviation improves work-related outcomes in this population, which is the focus of this analysis. A sample of 1028 depressed HIV clients in Uganda enrolled in a comparative trial of depression care models and were surveyed over 12Â months. Serial regression analyses examined whether depression alleviation (measured by the nine-item Patient Health Questionnaire) was associated with change in self-reported weekly amount of hours worked and income earned, and whether these relationships were mediated by change in work-related self-efficacy. Among those with major depression, depression alleviation was associated with nearly a doubling of weekly hours worked in bivariate analysis. The relationship between depression alleviation and hours worked was partially mediated by change in work self-efficacy among those with major depres...

This study provides insights into the perceived prevalence and patterns of alcohol and drug use among Palestinian youth. The study was based on ten focus groups and 17 individual interviews with youth aged 16-24 years (n = 83), collected as part of the formative phase of a cross-sectional, population representative study of risk taking behaviors among Palestinian youth in the West Bank in 2012. Qualitative analysis was used to code detailed notes of focus groups and interviews. Most participants reported that substance use exists, even in socially conservative communities. Almost all participants agreed that alcohol consumption is common and that alcohol is easily available. The top alcoholic drinks referred to by the study participants were vodka, whisky, beer, and wine. Most partic...

A sample of 1028 depressed HIV clients in Uganda enrolled in a cluster randomized controlled trial of two depression care models, and were surveyed over 12Â months. Serial regression analyses examined whether depression alleviation was associated with self-reported antiretroviral therapy (ART) adherence and clinic attendance at month 12, and whether these relationships were mediated by self-efficacy and motivation. Among those with major depression, depression alleviation was associated with better ART adherence and clinic attendance at month 12; these relationships were fully mediated by self-efficacy at month 12, while adherence motivation partially mediated the relationship between depression alleviation and ART adherence. When both mediators were entered simultaneously, only self-efficacy was a significant predictor and still fu...

We conducted a cluster randomized controlled trial of two task-shifting models to facilitating depression care delivered by medical providers: one that utilized a structured protocol, and one that relied on clinical acumen, in 10 HIV clinics in Uganda. Both models started with routine depression screening of all clients at triage using the 2-item Patient Health Questionnaire (PHQ-2), from which we enrolled 1252 clients (640 at structured protocol clinics, 612 at clinical acumen clinics) who had screened positive over 12 months. We compared the two models on (1) proportion of all client participants, and those clinically depressed (based on survey-administered 9-item PHQ-9>9), who received post-screening evaluation for de...
