This study was designed to determine the nature, incidence, and coincidence of forms of interpersonal conflict and resulting conflict management styles, including physical violence, in an existing nationally-representative cohort of 18 to 32 year old adults between the years 2016 to 2018. Respondent reports of conflicts involving aggressive and violent behavior were distinguished for three relationship categories: intimate partner relationships, friends/acquaintances, and relatively unknown persons/strangers. The research design covered questions about the nature and frequency of conflicts experienced irrespective of whether the incidents ended violently; conflict management style/tendencies (remedial actions, apologies, accounts); and differences between conflicts that turn violent and those that do not. Additional questions covered include the frequency of violence during the course of disputes, including experiences with physical victimization and the perpetration of violent acts was assessed. Also elements that facilitate conflict escalation that are deemed important theoretical constructs in research on aggression, such as adverse childhood events, low self-control, negative affect, street code attitudes, routine activities/lifestyles, agreeableness, and alcohol and drug use, in addition to demographic and other person-level variables were investigated.

The purpose of the Interpersonal Conflict and Resolution (iCOR) study was to inform research on the prevalence and etiology of conflict, victimization, offending and the commonly identified phenomenon referred to as the 'victim-offender overlap' in criminology.

The researchers conducted three waves of data collection among young adults ages 18-32 ("Primes"). At wave 2, the researchers recruited the intimate "Partners" of the prime respondents for a cross-sectional dyadic survey.

The research collected information from multiple sources and produced four datasets (iCOR.Wave1.PRIME.sav, iCOR.Wave2.PARTNER.sav, iCOR.Wave2.PRIME.sav, and iCOR.Wave3.PRIME.sav). The variables include information on demographics, communication, childhood trauma, relationships, personality, physical abuse, verbal abuse, substance abuse, morbidity mental health, physical health, and food preferences.

A Nationally-representative cohort of 18-32 year old adults who reside in the United States. Smallest Geographic Unit: Region

The project started with the recruiting of a nationally representative sample of 4,714 households with at least one household member falling in the target age range. From this initial sample (n=2,284), young adults participated in the wave 1 baseline survey conducted from August 2016 through April 2017. These respondents are the iCOR "Prime" respondents At wave 2, Prime respondents (n=1,629) completed a survey that was conducted from December 2016 through September 2017. Among this group, 1,328 of these Prime respondents reported that they were in a romantic relationship. Prime respondents who indicated that they were involved in more than one romantic relationship were asked to pick the person with whom they spend the most time, who was subsequently selected to the study and referenced in ensuing questions. Of these Prime respondents with a confirmed and selected Partner, 50 percent provided contact information to refer their Partner to the dyadic iCOR survey. Contact information was confirmed enabling invitations to Partners respondents (n=480), among whom completed cross-sectional surveys from December 2016 through October 2017. At wave 3, only the Prime respondents were surveyed from June 2017 through May 2018. Of the 2,204 Prime respondents invited to the wave 3 survey, there was a follow-up response rate of 70.1 percent within the iCOR cohort of Prime respondents (n=1,603).
