The authors have developed and tested scale-up methods, based on a simple social network theory, to estimate the size of hard-to-count subpopulations. The authors asked a nationally representative sample of respondents how many people they knew in a list of 32 subpopulations, including 29 subpopulations of known size and 3 of unknown size. Using these(More)
Attitudinal acceptance of intimate partner violence (IPV) is an important correlate of violent behavior. This study examined acceptance of IPV using data collected from a nationally representative telephone survey of 5,238 adults. Multivariable logistic regression analyses were used to test for associations between sociodemographic characteristics, exposure(More)
We asked respondents how many people they knew in many subpopulations. These numbers, averaged over large representative samples, should vary proportionally to the size of the subpopulations. In fact, they do not. We give two different interpretations of this finding. The first interpretation notes that the responses are linear in subpopulation size for(More)
PURPOSE Given the high rate of dating violence between teens and associated deleterious outcomes, the need for effective prevention and early intervention programs is clear. Break the Cycle's Ending Violence curriculum, a three-class-session prevention program focused on legal issues, is evaluated here for its impact on Latino/a youth. METHODS Tracks(More)
Like many researchers, we want to know the rules that govern the formation of human social networks, their persistence and disappearance, and their effects (if any) on human behavior and thought. Even if it turns out that the rules governing social network formation and decay are relatively simple, the outcome of those rules is very complex. It is so(More)
Estimating sizes of hidden or hard-to-reach populations is an important problem in public health. For example, estimates of the sizes of populations at highest risk for HIV and AIDS are needed for designing, evaluating and allocating funding for treatment and prevention programmes. A promising approach to size estimation, relatively new to public health, is(More)
Concerns have been raised regarding the appropriateness of asking about violence victimization in telephone interviews and whether asking such questions increases respondents' distress or risk for harm. However, no large-scale studies have evaluated the impact of asking such questions during a telephone interview. This study explored respondents' reactions(More)
The authors examine attitudes about help seeking and help giving related to dating violence among Latino ninth graders, including survey and focus group data. Latino teens are more likely to seek help for a dating violence situation from informal sources of support (e.g., friends) than from formal sources (e.g., health professionals). Students are most(More)
This qualitative study, utilizing focus group interviews with community members and in-depth interviews with victims and perpetrators, explored Latinos' beliefs and perceptions of IPV in Oklahoma City, Oklahoma, as a basis for developing culturally appropriate intimate partner violence (IPV) services for this population. The findings from these interviews(More)
This article estimates the variation in personal network size, using respondent data containing two systematic sources of error. The data are the proportion of respondents who, on average, claim to know zero, one, and two people in various subpopulations, such as ‘‘people who are widows under the age of 65’’ or ‘‘people who are diabetics.’’ The two kinds of(More)
