The program ran over 5 ½ years and was preceded by a one-year pilot study. It had been planned as a longitudinal comparative study in five European countries: France, (Federal Republic of) Germany, Great Britain, The Netherlands, and Sweden. Financial support came from the Max-Planck-Gesellschaft (Germany) and the research councils of France (CNRS), The Netherlands (NWO), Switzerland (FNS), and Norway (NAVS). deu|ita|ara|fra|tur|fin|eng|swe|spa|pan|nld
