Personality in Adulthood: A Five-Factor Theory Perspective Book

This book merges the fields of personality and developemental psychology (adult development / gerontology) and its main premise is that personality as assessed by Five Factor Theory is stable in adulthood. The major portion and energy of authors is spend in defending this position and alongside one gets a rich overview of methodological issues in measuring personality, not only traits but also other approaches like projective tests and interviews.
We now know that this simplistic interpenetration that personality is stable is not correct and picture is more nuanced with some traits showing predictable trajectory over the lifespan.
I found the last few chapters much more useful - the rest seemed polemic- defending ones turf of trait based FFT. This could have been a better book, if the authors had exercise more openness to experience and were not dismissive of other approaches.
