Only a few reports have analyzed dissimilarities involving occupant-reported and investigator-verified prevalence of moisture and mildew observations in properties. Douwes et al. (1999) found that occupant's reviews of damp spots or mold places had been far better correlated having a evaluate of indoor mould than investigator's studies of such seen signs. Bornehag et al. (2001) concluded that, Though for most research occupants experienced noted additional dampness than investigators had, this was as a result of occupants' more time time standpoint compared to the investigators' “snapshot” observations.

(1998) claimed similar outcomes, suggesting that the explanation was a result of a experienced eye and of expertise in what signifies a significant problem. Dharmage et al. (1999a) examined the validity and dependability of interviewer-administered questionnaires versus observations and measurements produced by an unbiased researcher. Amongst 44 goods examined for validity (described as correspondence among occupant stories and unbiased observations or objective measurements), there was best or Just about fantastic agreement on 21 and substantial arrangement on 19 Some others.
