knowing what to do when hearing an alarm ( p = 0.042), family
picking a place after escape to meet ( p = 0.002), and children
being able to dial 911 ( p = 0.034). That is, for the above
categories, time was the only predictor that impacted outcomes
thus justifying pooling our samples (e.g., family type –
child with and without special needs or classroom vs.
individual instruction) to evaluate if the DVD modality
improved outcomes over time.
