Description

The Learning Initiative on Norms, Exploitation and Abuse (LINEA) is a cluster randomised controlled trial (CRCT) of an intervention (radio drama and curricula) which aims to prevent age-disparate transactional sex in Tanzania.

This dataset contains the responses to structured surveys conducted at baseline before randomisation to and implementation of the LINEA intervention, among a cohort of adolescent girls aged 13-15 years and a cohort of young men aged 23-50 years. The surveys covered topics including socio-demographics, schooling, sexual behaviour, receipt and giving of gifts in the context of sex, experience of violence, attitudes to violence, and attitudes to age-disparate transactional sex.

Data collection methods

Adolescent girls were randomly selected from lists of girls attending forms 1 to 3 in public schools in the study wards (small areas within districts). Young men were recruited from the same wards, primarily from lists of boda boda (motorcycle taxi) drivers who were members of driver unions working in those wards at selected boda boda stands. Individual structured interviews were conducted in person by trained interviewers, with the aid of tablet devices (questionnaires programmed in ODK). 400 girls and 460 men participated, whose data are included in the datasets.

Data analysis and preparation

Data cleaning steps included checks for duplicate IDs, missing data, verifying age of respondent, consistency checks across related variables, and checks for correct application of questionnaire filters. The dataset was anonymised with each record assigned a unique numerical ID.

Geographic regions

Cross-sectional survey data were collected in Misungwi, Ilemela and Geita Districts, Mwanza Region, Tanzania. These districts and wards were selected purposively, primarily based on radio station coverage with the intervention radio drama (wards with no radio drama coverage in Geita intended to serve as a control in the quasi-experimental
