Not many researches have been investigating the relationship of perfectionism with adaptive aspects of human behaviour. For that reason, aim of this study was to investigate the relationship of positive and negative perfectionism with adaptive measures of self-esteem and satisfaction with the quality of life, and to find out the differences between adaptive perfectionists, nonadaptive perfectionists and nonperfectionists in these measures. Instruments used are Positive and Negative Perfectionism Scale, Rosenberg Self-Esteem Scale and one item question about how a person is satisfied with his/her life as a whole. The results showed positive relationship of positive perfectionism with self-esteem and assessment of satisfaction with life, and negative relationship of negative perfectionism with these variables. Further more, the results indicated that nonadaptive perfectionists had lower levels of self-esteem than adaptive perfectionists and nonperfectionists, while there was no such difference between these two groups. Results also showed no differences between these groups of perfectionists and nonperfectionists in the assessment of satisfaction with life variable.Malen broj istraživanja se bavio povezanoću perfekcionizma s adaptivnim aspektima čovjekovog ponašanja i doživljavanja. Stoga je cilj ovog rada bio istražiti povezanost pozitivnog i negativnog perfekcionizma s adaptivnim mjerama samopoštovanja i zadovoljstva kvalitetom života, te utvrditi razlike između adaptivnih i neadaptivnih perfekcionista te neperfekcionista u navedenim mjerama. Korišteni mjerni instrumenti su Ljestvica pozitivnog i negativnog perfekcionizma, Rosenbergova ljestvica osobnog samopoštovanja te jedna čestica koja postavlja pitanje koliko je osoba, u cjelini gledajući, zadovoljna kvalitetom vlastitog života. Rezultati su ukazali na pozitivnu povezanost pozitivnog perfekcionizma sa samopoštovanjem i procjenom zadovoljstva kvalitetom života, te negativnu povezanost negativnog perfekcionizma s navedenim varijablama. Pokazalo se i da neadaptivni perfekcionisti imaju značajno nižu razinu samopoštovanja u odnosu na adaptivne perfekcioniste i neperfekcioniste, dok između tih dviju grupa nije bilo razlike. Međutim, nisu dobivene nikakve razlike između adaptivnih, neadaptivnih perfekcionista i neperfekcionista u procjeni zadovoljstva kvalitetom života
