This study concerns life satisfaction and its determinants in Dutch young adults with spina bifida (SB). Data on life satisfaction (Life Satisfaction Questionnaire ) were related to hydrocephalus, lesion level, disabilities, and demographic variables. In total, 179 young adults with SB participated (41% male, age range 16-25y; 79% SB aperta, 67% hydrocephalus [HC], 39% wheelchair-dependent). Most were satisfied with their life as a whole (24% dissatisfied). No difference was found from a population reference group (28% dissatisfied). Highest proportions of dissatisfaction were found for financial situation (44%), partnership relations (49%), and sex life (55%). Least dissatisfaction was found for contact with friends (17%) and families (15%). Young adults with SB and HC were more satisfied with their financial situation and family life but were less satisfied with self-care ability and partnership relations than those without HC and the reference group. However, except for self-care ability, relationships between life satisfaction and having SB were weak. In conclusion, self-care ability and partnership relations were rated least favourable and may need more attention from care providers. Overall, SB does not seem to be an important determinant of life satisfaction.Spina bifida (SB) is a congenital condition that may result in a wide variety of physical and cognitive limitations. 1-7 After the initial hazardous years, the survival rate for a person with SB is near normal, 8,9 although hydrocephalus (HC), bladder management, and kidney-sparing always remain an issue. 7,9 Several authors have proposed that chronic conditions such as SB confront youngsters with additional barriers in the transition from adolescence to adulthood compared with their typically developing peers. 10-12 They may find themselves, for example, disadvantaged with regard to career opportunities or finding a partner. Better insight into the quality of life (QoL) of young adults with SB might identify support needs and might, thereby, provide a basis for improving the support system. Knowledge of the QoL of persons with SB is also relevant with regard to today's policies of aborting pregnancies early in gestation, the use of new operation techniques such as in utero closure of the neural tube, 13 and deciding whether or not to treat early after birth. Such decisions by medical professionals are based on, among other considerations, the expected long-term QoL of the patients involved. However, professionals tend to rate the QoL of their patients much lower than the patients themselves do. 14 Only limited research into the QoL of persons born with SB is available, and the results are equivocal. Some authors 15 found that the healthrelated QoL of their study population was below normal, whereas others concluded that QoL was good 10 and comparable to that of persons without SB. 11,16 QoL is a notion with a rather broad meaning, but it is usually associated with well-being or life satisfaction. 17 Defining life satisfaction as an element of QoL, ra...
