摘要：This paper presents a number of issues related to research instruments reliablility estimators. The first part presents an introduction into the field of instruments reliability and reliability estimators reviewing some important research in this field. The objectives of the doctoral thesis focuses on the discovery of external influences on the value of reliablility estimators,objectives outlined in the second chapter of the paper. In the third part,Cronbach Alpha estimator is briefly described,with its advantages and disadvantages,while in the final part are presented some limitations of this estimator and a possible solution to overcome a part of them. By overcoming these limitations and by finding possible external factors that influence reliablility estimators we can ease the titanic work that marketing field researchers realizes to adapt their research instruments to the environment (target population).
