Adams is an assistant professor of Ecological/Community Psychology at Michigan State University.
She has also examined the economic and mental health impacts of job instability stemming from intimate partner abuse, as well as studied the effects of adolescent dating violence on girls’ educational attainment and earnings in adulthood. Adams is exploring the problem of coerced debt, a form of economic abuse that occurs when an abuser obtains credit in their partner’s name via fraud or coercion. Adams also has expertise in evaluating community-based interventions and victim service programs at the local, state, and national level.None of these studies used nationally representative samples, yet they draw conclusions about differences between nations.This article provides empirical data on whether valid cross-national conclusions can be made using these types of unrepresentative samples when the samples are drawn from the same subpopulations in each country and using similar study designs.It reports empirical tests of the cross-national validity of data obtained for a 32-nation study using convenience samples of university students – the International Dating Violence Study or IDVS.The IDVS sample is not representative of the 32 nations because university students differ from the general population in important ways.In addition, because the sample consisted of students in classes taught by the member of a research consortium in that nation and in classes where other teachers permitted the questionnaire to be administered, the students in IDVS are not random samples of students in their nation, or even of students in their own university.
Members of the consortium conducting the study administered the study questionnaire in enough of their own and classes taught by others.
Concurrent Validity Concurrent validity of nation-level measures based on non-probability samples is measured by the degree to which variables from the non-probability samples are correlated with measures of the same variable based on presumably representative national statistics.
She works collaboratively with organizations to build their capacity to evaluate their services and learn from the evaluation process and findings.
To that end, she developed and facilitates a “Putting Evaluation to Use” workshop that engages stakeholders in the data interpretation process in order to provide them with an opportunity to reflect on their work, celebrate successes, identify areas for improvement, and plan for change. Adams is invested in using her research and evaluation work to strengthen the community and policy response to intimate partner abuse in order to improve women’s economic well-being and general quality of life.
Many multi-nation surveys use samples that are not representative of the nations compared.
Examples include surveys of students or families of students in different nations (Straus 1968; Straus and Straus 1968), of nurses (Glazer and Gyurak 2008), and of residents of the largest city in each nation in the study (Lynch 2008).
