title: Hungarian Nationally Representative Community Sample of the Hungarian Version of the Experiences in Close Relationships Revised (ECR-R-HU) Questionnaire

description: Online data collection was carried out in a nationally representative online sample by a Hungarian company (Social Research Ltd.), an expert in social surveys and data collection. 16,000 members of the company’s research community were invited to participate voluntarily in the research via email, in which no preliminary information was given on the subject of the survey. The voluntary sample was stratified according to gender, age, education, and settlement type. Following the stratification, the respondents were randomly selected in order to obtain a final, nationally representative sample. There were five age groups (18-29, 30-39, 40-49, and 50-59 years of age, and 60 years or older), and three categories of education level (primary and vocational school, secondary, and higher education). The stratification of the sample was completed by adjusting the true proportions of settlement type (capital, cities/towns, and villages) and regions (Central, Eastern, and Western Hungary).The total sample size was <i>N</i> = 993, but the number of respondents to the ECR-R-HU questions was <i>N</i> = 958, as the questionnaire was not offered to participants who had never been in a romantic relationship. Four months after the first wave of data collection in December 2018, a second wave was carried out in a smaller subsample (<i>N</i> = 98) of the original sample. The number of male and female participants in the whole sample (Wave 1) was approximately equal. The average age of participants was <i>M</i> = 47.89 (<i>SD</i> = 13.85) with all age groups from 18 to 89 appropriately represented and almost half of the sample was middle-aged (between 40 and 60 years old). Somewhat more than half of the respondents lived in country towns, the remaining 20% and 23% lived in the capital and in villages, respectively. Two thirds of the participants graduated at least from secondary school. Most respondents (78.2%) were either in a romantic relationship or married at the time of the survey. The demographic characteristics of the Wave 2 subsample proved not to be representative. <b><i></i></b>Participants used an online platform to complete the 25-minute survey. In addition to socio-demographic questions and the ECR-R-HU, they were given the Hungarian version of four questionnaires (WHO Well-being Questionnaire (WBI-5), Perceived Stress Scale-4 (PSS-4), Depression Scale Questionnaire (DS1K), Family Assessment Device (FAD)) in order to test the convergent validity of the ECR-R-HU. ECR-R-HU is the Hungarian translation of the ECR-R (Fraley et al., 2000), a 36-item self-report measure of adult attachment. The instrument includes two subscales (<i>Avoidance, Anxiety</i>) that assess attachment-related anxiety and avoidance, each with 18 items. Participants used a 7-point Likert-type scale to indicate their level of agreement with each item, where 1 = strongly disagree and 7 = strongly agree. Participants received the following instructions: “Please take a moment to think about your previous and current romantic experiences and indicate the level of your agreement with each statement”.The survey was approved by the Research Ethics Committee of Semmelweis University Budapest, Hungary, license number RKEB: 197/2018.
