This paper examines whether an experimental intervention for girls aged 14-19 that provided reproductive health information, vocational counseling and training, and assistance with opening savings accounts in slum areas of Allahabad in Uttar pradesh, India, had an effect on their attitudes and behaviours. A quasi-experimental pre- and post-test design was used in which adolescent girls were compared with girls of the same age residing in control-area slums. Although the livelihoods program was acceptable to parents and feasible to implement, the project had only a minimal impact on the behaviour and attitudes of adolescent girls taking part in the project. Girls exposed to the intervention were significantly more likely to have knowledge of safe spaces, be a member of a group, score higher on the social skills index, be informed about reproductive health, and spend time on leisure activities than were the matched control respondents. No effect was found on gender role attitudes, mobility, self-esteem, work expectations, or on number of hours visiting friends, performing domestic chores, or engaging in labour market work
