This data set contains the results of data collection survey using the Respondent Driven Sampling method. The contents include sexual intercourse among early adolescents, sociodemographic characteristics and intermediary factors that are believed to cause adolescent engaged in sexual intercourse. Raw data is prepared according to the format used to analyze it using RDSAT version 7.1.46


Steps to reproduce

Raw data were prepared in Microsoft Excel according to the format for RDS (including the subject ID, network size, subject vouchers, and a maximum of six entries for the voucher numbers given). Excel files in csv format were imported into RDSAT 7.1.46. Data collection procedures: A structured questionnaire adapted from the Indonesian Global Early Adolescents Study (GEAS) was employed. It covered sociodemographic characteristics as well as information regarding the frequency of discussing sexuality with parents, attitudes towards sexual intercourse, intention to engage in sexual intercourse, involvement in sexual intercourse, and reasons for having sexual intercourse. Population and sample recruitment: Very young adolescents were eligible to participate if they 1) were very young adolescents 10-14 years old, either male or female, who lived in Semarang; 2) were believed to have had sexual intercourse, based on the assumption of the recruiter; 3) had a valid RDS voucher; 4) agreed to join the survey by signing an assent form and their parents signing an informed consent form; and 5) had not previously participated in this survey. Based on the inclusion criteria, we used a key question to recruit participants. The question was, "Are there any of your close friends aged 10 to 14 years old in Semarang who you think have had sexual intercourse?” Since the RDS method is able to reveal hidden populations, we could reach very young adolescents by recruitment who were believed by the recruiter to have had sexual intercourse, regardless of whether they had actually participated in this behavior. Therefore, we categorize this population as very young adolescents believed to have had sexual intercourse (VYABTHHSI). The field workers went to the houses of prospective respondents to meet with the prospective respondent and his or her parents or guardians to explain the research process and to obtain approval for data collection. The data collection point was offered to potential respondents, whether at home or elsewhere, depending on the respondent's request. RDS was conducted with the same criteria as the seed subject. After they gave informed consent and assent, each subject seed was asked to complete the self-administered questionnaires provided on a tablet through the Open Data Kit (ODK). Self-administered questionnaires using ODK are needed to obtain the actual conditions experienced by participants. Respondents were asked to give the recruitment voucher to friends they knew who had previously had sexual intercourse. Then, the friends were required to contact the researcher and perform the procedure for data collection. Respondents were allowed to exchange the gift voucher for an additional incentive after their friends who received the recruitment vouchers filled in the questionnaires in the ODK.
