The dissociative thesis states that social mobility is a disruptive and detrimental experience for the individual. Despite the absence of convincing evidence either for or against it, this thesis is generally accepted in sociology. I investigate this thesis by considering three dimensions of dissociation—i.e., social isolation, utilitarian individualism, and social disorientation. I use data from a large-scale survey in Flanders (Belgium) and apply Diagonal Reference Models to study the consequences of intergenerational social mobility. I find support for asymmetric acculturation for each dimension, i.e., upwardly mobile individuals adapt more to the new social status position, compared to downwardly mobile individuals. Moreover, both for social disorientation and utilitarian individualism, I find detrimental effects of the experience of downward social mobility. As I find no detrimental consequences of both upward and downward mobility, the results do not provide evidence for the dissociative thesis.
