Aim

To assess the self-efficacy of patients undergoing systematic desensitisation in relation to their behaviour with previously phobic objects.

Method and Design

A Quasi-experiment.

Participants

The participants all had a snake phobia, which is why the experiment was quasi. Bandura could not have randomly assigned people to groups, either participants had a fear of snakes or they did not.

The participants were 10 snake phobic patients who replied to an advertisement in a newspaper. 9 Females and 1 Male aged 19-57 years old.

There was not a control group used in this study.

Procedure

Pre-test assessment: each of the participants were tested for avoidance behaviour towards a Boa constrictor, then fear arousal was assessed with an oral rating of 1-10. Efficacy expectations (how much they thought they would be able to complete tasks involving snakes) Fear of snakes also measured.

Systematic desensitisation: a standard desensitisation programme was followed. Patients were introduced to a series of events involving snakes and at each stage were taught relaxation. Ranged from looking at pictures of snakes to handling live snakes. Post test assessments carried out were on self efficacy and coping.

Findings

Higher levels of post test self-efficacy were found to correlate with higher levels of interaction with snakes. The more the participant interacted with snakes, the higher their level of self-efficacy. 

Conclusion

Desensitisation enhanced self-efficacy levels which, in turn, led to a belief that the participant was able to cope with their phobia of snakes.

Bandura (1977) Evaluation

– Generalisability – the sample was small and gynocentric, however there was a wide range of ages.

– Demand characteristics may have been present due to the nature of the study and the self-reports.
