The theory which underpins this case study is Behaviourism. According to (Santrock, 2005, p.55), behaviourism emphasizes the scientific study of observable behaviour and their environment determinants. It is therefore, built around the work of Ivan Pavlov and B.F Skinner who claim that all behaviours are acquired through conditioning. Our behaviour is shaped through environmental stimuli, hence conditioning occurs.
However, four reasons for selecting this theory are as follows: Firstly, behaviour can be studied in a systematic and observable manner to understand how an individual develops and personality is formed, meaning that the youth development worker was assigned there to conduct
a study of the behaviour of the women also the environment in which they lived to why their behaviour and personality are formed as a result the worker enabled the women to express their frustrations and problems in a discussion manner . Secondly, rearranging experiences can change personality development and behaviour, whereas the women will worked assiduously to prevent further pregnancies, since they felt it would get in their way in becoming contributing citizens. Thirdly, reinforcement or elimination of behaviours through positive or negative strategies, in so doing the youth worker and the women planned programme of activities in which they implemented, including educational and skill training and recreational activities. Finally, a focus on the environment in order to determine youth behaviour, it therefore looks at the type of in environment in which the women lived and what influences them to become pregnant and single moms at those ages. For example lack of family and financial support and also where unemployment rate is high in the environment can lead to such behaviour of the women.
