Living donor kidney transplantation offers advantages to the patient, however involves risks to the donor. To optimize donors' mental health after donation, we studied the influence of psychological factors on this outcome. Potential predictors were based on models of Lazarus (1999) and Ursin and Eriksen (2004) that describe predictors of mental health mediated by stress.Design
Living kidney donors (n = 151) were interviewed before donation and completed questionnaires 2.5 months before and 3 and 12 months post-donation. Using multilevel regression models, we examined whether appraisals, expectations, knowledge, social support, coping, life events, and sociodemographic characteristics predicted psychological symptoms and well-being and whether these relationships were mediated by stress.Results
A greater increase in psychological symptoms over time was found among donors without a partner. Younger age, lack of social support, expectations of interpersonal benefit, lower appraisals of manageability, and an avoidant coping style were related to more psychological symptoms at all time points. The latter three were mediated by stress. No religious affiliation, unemployment, history of psychological problems, less social support, expectations of negative health consequences, and less positive appraisals were related to lower well-being at all time points.Conclusions
This study identified indicators of a lower mental health status among living kidney donors. Professionals should examine this profile before donation and the need for extra psychological support in relation to the number and magnitude of the identified indicators. Interventions should be focused on the changeable factors (e.g., expectations), decreasing stress/psychological symptoms, and/or increasing well-being.Statement of contribution
What is already known on this subject?Statement of contribution
Until now, research on psychological outcomes after living kidney donation revealed that mental health remained the same for the majority of living kidney donors, while mental health improved or deteriorated for a minority after donation. In reaction to these findings, many psychosocial screening guidelines have been developed for potential donors; however, the components of these guidelines are based on professional opinions and experience rather than on longitudinal empirical data. There is a lack of research that identifies pre-donation donor characteristics that are related to a lower mental health among donors. Such studies are essential in order to tailor psychosocial support during the donation process.Statement of contribution
