A SOCIOLOGICAL APPROACH TO VALIDATE A QUESTIONNAIRE FOR THE ASSESSMENT OF SYMPTOMS AND PERCEPTION OF INDOOR ENVIRONMENT IN DWELLINGS

摘要

A standardised questionnaire for dwellings - the Stockholm Indoor Environment Questionnaire (SIEQ) was developed, based on sociological principles and test procedures for validation. The every day language describing the building and its function was first obtained by qualitative personal interviews, then by standardised questions. The interview questionnaire was transformed into a postal self- administered questionnaire. The questionnaire was reduced by correlation analysis. It was found that to obtain a good validity, general questions are not sufficient, but also questions on perception and observations are needed. Good test- retest agreement was found for a random sample when investigating the same area, and the same buildings.
