Only a few research have analyzed discrepancies amongst occupant-documented and investigator-confirmed prevalence of humidity and mold observations in structures. Douwes et al. (1999) discovered that occupant's studies of damp places or mold spots were being much better correlated by using a evaluate of indoor mildew than investigator's studies of such visible indicators. Bornehag et al.

(1998) documented related outcomes, suggesting which the explanation was a result of a trained eye and of expertise in what represents a important dilemma. Dharmage et al. (1999a) examined the validity and trustworthiness of interviewer-administered questionnaires from observations and measurements created by an independent researcher. Amid forty four products examined for validity (outlined as correspondence concerning occupant reviews and unbiased observations or objective measurements), there was ideal or Practically great agreement on 21 and considerable settlement on 19 Many others.
