A conflicting review by Williamson et al. (1997) discovered that occupants documented dampness fewer frequently than skilled surveyors. Nevalainen et al. (1998) described identical results, suggesting the explanation was a result of a experienced eye and of expertise in what signifies a crucial difficulty. Dharmage et al. (1999a) examined the validity and trustworthiness of interviewer-administered questionnaires versus observations and measurements made by an independent researcher.
