Evaluated a programme designed to help pregnant teenagers resist smoking
Social support was provided to some of the teenagers by an older mentor
At the end of the 8 week programme, they found the participants who had a mentor were less likely to smoke than the control group who did not have a mentor
They are believed to be able to resist the pressure to conform and obey
They tend to be more self-confident, intelligent and achievement-orientated, which provides them with personality traits that give them greater resistance to social control
37% of participants with high internal locus of control did not continue to the highest shock, whereas only 24% of participants with high external locus of control did not continue to the highest shock level
If they have previously obeyed or conformed to a situation, it is likely they would do so again, no matter whether their locus of control is internal or external
