Study Purpose View help for Study Purpose

This research project was a secondary data analysis of the 2010 National Intimate Partner and Sexual Violence Survey (General Population Data). Specifically this project sought to (1) identify the prevalence of intimate partner violence, stalking and sexual violence among non-college-attending emerging adults and (2) explore the use of formal and informal help seeking and formal services among these victims.

Within these goals, the project had five primary objectives:

1. To describe the prevalence of intimate partner violence, stalking and sexual violence among non-college-attending emerging adults.
2. To describe the utilization of informal and formal help seeking including the helpfulness of these contacts to the victim.
3. To describe perceived needs for particular victim services as well as barriers to accessing these services.
4. To identify the contexts that are most common for victims to seek and use services as well as those in which services are less likely to be used
5. To disseminate the findings obtained to practitioner and researcher audiences.

Study Design View help for Study Design

The survey was conducted in 50 states and the District of Columbia and was administered using a computer-assisted telephone interview from January 22, 2010 through December 31, 2010. In 2010, a total of 18,049 interviews were conducted (9,970 women and 8,079 men) in the United States general population. This included 16,507 completed and 1,542 partially completed interviews. A total of 9,086 females and 7,421 males completed the survey. Approximately 45.2 percent of interviews were conducted by landline telephone and 54.8 percent of interviews were conducted using a respondent's cell phone.

Violence Against American Indian and Alaska Native Women and Men: 2010 Findings from the National Intimate Partner and Sexual Violence Survey (NISVS) Data

Dataset 1 (General Population Raw Data) employed a dual-frame, stratified random digit dial (RDD) sampling design, with continuous data collection. To meet the challenges of rising non-coverage rates in United States landline-based telephone surveys, NISVS implemented a dual-frame design where both landline and cell phone frames were sampled simultaneously.

List-Assisted Landline Frame: The landline sampling frame was comprised of hundred-banks of telephone numbers where each bank had at least one known listed residential number. A hundred-bank is the 100 telephone numbers that are generated by fixing the first eight digits of a telephone number and changing the last two digits (e.g., (800) 555-55XX). Known business numbers were excluded from the frame. In addition, non-working numbers were removed after sample selection through screening.

Cell-Phone Frame: The cell phone frame consisted of phone numbers in telephone banks identified as active and currently in use for cell phones. At the time the sample was drawn, directory listings of cell phone numbers were not available. Thus, list-assisted screening was not possible.

Stratification for State-Level Estimates: NISVS had the dual objectives of providing national and state-level estimates. A sample design optimized for national estimates would use proportionate allocation across states (resulting in a sample size in each state that is proportionate to the adult population in that state), whereas a design optimized for providing stable state-level estimates might allocate the sample approximately equally across states. Considering these competing objectives, NISVS survey samples were stratified by state, balancing between stable state-level estimates and weight variation for the national estimates from oversampling of smaller states.

Within-Household Selection: Each state sample included both landline and cell phone samples. When reaching a household in the landline sample, the interviewer asked about the number of males and females living in the household. In a one-adult household, the adult was automatically selected to participate. In households with only two adults, the person on the phone or the other adult in the household was randomly selected. When there were more than two adults in the household, the adult with the most recent birthday was selected. Because cell phones are personal use devices, the person answering the cell phone was selected as the respondent, if eligible.

Nonresponse Phase: To increase participation, NISVS was administered as a two-phase survey. Phase One was the main data collection phase. Respondents in the first phase were offered an incentive of 10 dollars to participate in the survey. A random subsample of non-respondents from the first phase was selected during Phase Two, with the goal of reducing non-response and non-response bias. The second phase included a substantially higher incentive (40 dollars) to further encourage participation.

Violence Against American Indian and Alaska Native Women and Men: 2010 Findings from the National Intimate Partner and Sexual Violence Survey (NISVS) Data

Dataset 1 (General Population Raw Data)

The questionnaire was divided into several sections and included information on demographic characteristics of the respondent, health conditions, victimization experiences (including psychological aggression, coercive control and entrapment, physical violence by an intimate partner, stalking victimization, and sexual violence). The questionnaire also included information about perpetrators and follow-up questions.

Demographics - Respondents were asked their year of birth, education level, race and ethnicity, place of birth (if not U.S. born, number of years lived in the U.S.), whether they were affiliated or enrolled in a tribe or village, whether they have ever and in the past 12 months lived on a reservation or in a tribal village, their total household income, and zip code

Health - Respondents were asked about the following health conditions: asthma, chronic pain, diabetes, difficulty sleeping, frequent headaches, high blood pressure, irritable bowel syndrome (IBS), general physical health, and mental health. They were also asked about activity limitations as a result of physical, mental, or emotional problems, and about health problems that require use of special equipment. They were also asked how often they worried or were stressed about having enough money to pay their rent or mortgage, buy nutritious meals, and times when they needed to see a doctor but couldn't afford it.

Victimization - Respondents were asked to report the number of people who had perpetrated a series of violence behaviors (described below) against them. For each perpetrator they reported, they were asked for the initials of the perpetrator and the number of times the perpetrator did the behavior ever, in the past three years, and in the past 12 months:

Psychological aggression (PA), which included behaviors such as acting dangerous, name calling, insults, and humiliation.

Coercive control and entrapment (CCE), which included behaviors that are intended to monitor and control an intimate partner such as threats, interference with family and friends, and limiting access to money. It also included behaviors intended to control reproductive or sexual health.

Physical violence (PV), which included behaviors such as slapping, pushing or shoving, being hurt by pulling hair, being hit with something hard, being kicked, being slammed against something, attempts to hurt by choking or suffocating, being beaten, being burned on purpose, and having a partner use a knife or gun against the victim.

Stalking (S), which included a pattern of unwanted harassing or threatening tactics used by a perpetrator that caused fear or concern for the safety of oneself or others, such as unwanted phone calls or emails, watching or following from a distance, technology assisted tactics (GPS), and leaving strange or potentially threatening items for the victim to find.

Sexual violence (SV), which included rape (completed forced penetration; attempted forced penetration; alcohol or drug facilitated completed penetration); being made to penetrate another person (completed; attempted - males only; alcohol or drug facilitated); sexual coercion (unwanted sexual penetration after being pressured in a non-physical way), unwanted sexual contact (e.g., being kissed in a sexual way, fondled or grabbed), and non-contact unwanted sexual experiences (i.e., unwanted experiences that do not involve any touching or penetration such as someone exposing their sexual body parts, flashing, or masturbating in front of the victim; making a victim show his or her body parts; making a victim look at or participate in sexual photos or movies; or someone harassing the victim in a public place in a way that made the victim feel unsafe).

Respondents aged 70 and older were also asked about perpetrators other than romantic and sexual partners for recent psychological aggression, coercive control and entrapment, and physical violence victimization (i.e., past 12 months only). These questions were included as a part of a pilot to assess the utility of using NISVS to capture some information on victimization among older adults.

Perpetrator Information - All behaviors in the NISVS survey were linked to a specific perpetrator and all questions were asked within the context of that perpetrator. Respondents who reported experiencing violence were asked to provide the interviewer with the initials or a nickname for the individual perpetrator or identify the person in some other general way so that each violent behavior reported could be tied to a specific perpetrator. Respondents were then asked a series of questions about each perpetrator including the perpetrator's age, sex, and race/ethnicity. In addition, for each perpetrator reported, respondents were asked their age and their relationship to the perpetrator, both at the time violence first began and at the last time violence was experienced.

Follow-up Questions - Respondents who reported experiencing stalking victimization were asked a series of follow-up questions, including the respondent's age when they first experienced stalking by each perpetrator and the age at which they last experienced stalking. They were also asked whether they were fearful, whether the perpetrator ever damaged personal property or belongings, ever threatened to physically harm them, and whether they believed that they or someone close to them would be seriously harmed or killed.

Respondents who reported being threatened with physical harm or physically forced to have sex were also asked a series of follow-up questions, including the respondent's age when they first experienced these behaviors by each perpetrator and the age at which they last experienced these behaviors. They were also asked whether they were physically injured, contracted an STD, or became pregnant as a result of the victimization.

A series of general follow-up questions were asked of respondents who reported victimization in the preceding sections of the survey (i.e., psychological aggression, coercive control and entrapment, and physical violence by an intimate partner; stalking, and sexual violence victimization). Respondents were asked about the impact of the violence they experienced by a specific perpetrator. These questions included whether they were ever concerned for their safety; if they were ever fearful (and if so, how fearful); if they had nightmares, were constantly on guard, watchful, or easily startled; if they felt numb or detached from others, their activities, or surroundings; if they were ever injured (and if so, what those injuries included); who they talked with about the behavior(s) (and if so, how helpful these discussions were); their need for and ability to get services (medical care, housing services, community services, victim's advocate or legal services); and whether they ever had to miss work or school.

Response Rates View help for Response Rates

Violence Against American Indian and Alaska Native Women and Men: 2010 Findings from the National Intimate Partner and Sexual Violence Survey (NISVS) Data

Dataset 1 (General Population Raw Data):The overall weighted response rate for the 2010 data collection for NISVS ranged from 27.5 percent to 33.6 percent. The computation of the weighted response rate reflected the stratified, two-phase, dual-frame survey design used in NISVS, and accounted for the disproportionate sampling across states, combined response rates from Phases One and Two, and combined response rates resulting from the two sampling frames.

The range in the overall response rates reflects differences in how the proportion of the unknowns that are eligible is estimated. The 27.5 percent was an estimate of the proportion of the unknowns that are eligible based on the information identified by interviewers when calling numbers. The upper estimate (33.6 percent) also included information from the prescreening process.

Violence Against American Indian and Alaska Native Women and Men: 2010 Findings from the National Intimate Partner and Sexual Violence Survey (NISVS) Data

Dataset 1 (General Population Raw Data)

Sample weights were essential for computing national estimates using these data. These weights reflected sampling features, non-response, coverage, and sampling variability. There were several main weight components that contributed to final sampling weights: selection, multiplicity, non-response, and post-stratification.

The selection weight accounted for different sampling rates across states, the varying selection probabilities in the landline and in the cell phone frames, the within household probability of selection, and the subsampling of non-respondents in Phase Two of data collection.

The multiplicity weight component took into consideration that some sample members had both landline and cell phone services, thereby having multiple chances of entering the survey. The non-response weight accounted for the variation in response rates within the selected sample.

The post-stratification weight adjusted the product of the selection, multiplicity, and non-response weights to match the population distribution on main demographic characteristics. This was accomplished using benchmark counts from census projections to correct for both coverage and non-response, which allowed the landline and cell phone samples to be merged together.

Two main sets of weights were computed for analyzing NISVS data. Applying the same principles in constructing the various weight components, one set of weights was computed for all partial and complete interviews, while another set of weights was computed for the complete interviews only. An interview was defined as "complete" if the respondent completed the screening, demographic, general health questions, and all questions on all five sets of violence victimization, as applicable. An interview was defined as "partial" if the respondent completed the screening, demographic, and general health questions and at least all questions on the first set of violence victimization (psychological aggression).

Users of NISVS data will need to provide the "design" and "stratum" specifications to whichever software (such as SUDAAN or a SAS complex survey procedure) is being used for analysis and apply the correct weights when producing estimates. This is necessary because the NISVS data were collected through a complex sampling design. Information about the Design and Weight Variables can be found in the Orientation to Analyzing the NISVS Raw Data documentation. Additional information can be found in the Technical Report.
