Background: Although positive mental health (MH) is a key concept for salut
ogenesis, longitudinal analyses of its development are lacking.
Objective: Investigation of antecedent factors for development of MH measur
ed by questionnaire vs. clinical expert ratings in Eastern and Western Germ
any.
Methods: The sample consisted of 525 25-year-olds from Eastern and Western
Germany investigated as part of two prospective longitudinal studies.
Results: Both forms of assessment showed considerable overlap. MII was sign
ificantly better in the Restock (East) sample; moreover women's MH was bett
er than that of men. Recent influences generally showed greater predictive
power for MH with 25 years than earlier predictors.
Conclusions: Sociopolitical and gender differences are important. Despite t
he greater influence of recent factors, some risks still show influence ove
r 25 years.
