Experiences of WAI in a random sample of the Swedish working population

The Work Ability Index seems to be a useful tool not only among older workers but also among the entire working population, but the distortion of the distribution should be taken into consideration when evaluating WAI results in healthy groups and when planning new studies. Further evaluations of the WAI instrument are needed regarding changes in demands in present working life, workers of different ages and in relation to other instruments that measure work ability.
