On the school level, observed indoor air problem (standardized b= 0.43) and poor teacher – student relationship (standardized b = 0.22) were significant predictors of poor subjective IAQ. In addition, school-related stress was associated with poor subjective IAQ, but only in schools without observed indoor air problem (standardized b=0.44).
