Psychological and cultural determinants of women's intentions to donate oocytes.
Purewal, Satvinder (2009) Psychological and cultural determinants of women's intentions to donate oocytes. PhD thesis, Middlesex University.
In oocyte donation, oocytes from one woman can be transferred to another for fertility treatment or used for medical research. However, there is an acute shortage of women from the general population donating their oocytes and this has adverse consequences for infertile patients and medical researchers. The aims of this thesis were to explore the psychological determinants of oocyte donation intentions and to investigate the link between oocyte donation intentions and parenthood using components of the Theory of Planned Behaviour (TPB) among women from different ethnic backgrounds. In doing so, a triangulation approach was adopted and one systematic review and five empirical investigations consisting of quantitative, qualitative and experimental research methodologies were carried out. Results revealed that oocyte donation is best accounted for by a diverse dimension of factors, which include positive attitudes towards oocyte donation, unconventional perceptions of parenthood and demographic variables. Some theoretical components of the TPB were supported; in particular Structural Equation Modelling found positive attitudes towards oocyte donation and subjective norms demonstrated a direct influence on the decision to donate oocytes. However, the role of perceived behavioural control in intentions to donate remains uncertain. Perceptions of the importance of parenthood and genetic ties between parent and child are key in determining [un]willingness to donate oocytes for fertility treatment. In addition, findings from this thesis suggest that it may be possible to modify intentions towards oocyte donation using the Framing Effect among White women, but not Women from South East Asia. The results of this thesis have some important implications for research and clinical practice, particularly in its potential to tailor clinical service provision regarding the recruitment of oocyte donors.
