Persistent identifier

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. There is a quasi-experimental, non-randomised, component which aims to estimate impact of the intervention on community-wide social norms.

This dataset contains the responses to a structured survey conducted at baseline before randomisation to and implementation of the LINEA intervention, among general populations of girls/women and boys/men aged 13 years and over. The surveys covered topics including socio-demographics, schooling, sexual behaviour, receipt and giving of gifts in the context of sex, attitudes to violence, and attitudes to age-disparate transactional sex.

Data collection methods

Participants for the cross-sectional survey were sampled using multi-stage sampling; first sampling wards within selected study districts, then by randomly selecting streets, then households within those streets (random selection of the first house, systematic thereafter). Individual structured interviews were conducted in person by trained interviewers, with the aid of tablet devices (questionnaires programmed in ODK). 599 women and 600 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 evaluation).

Key dates

• Data capture began on 19 July 2023 and ended on 07 October 2023.

Quality controls

Periodic checks (as indicated above – data preparation section) were performed on partial datasets by the LINEA data manager and analysts, in real time as the data collection was in progress to highlight any issues with scripting or administration of the survey.

Population

General populations of girls/women and boys/men aged 13 years and above in the selected wards and districts.

Privacy

To protect the privacy of participants, names are not included, only unique study IDs. Date of birth is not contained in the dataset, only month and year of birth.
