The Naomi anxiety scale was a scale that measured Naomi Wildman's anxiety level, according to Neelix. One was a touch of insomnia, while ten was a panic attack.
In 2375, Naomi's mother Samantha Wildman was among those missing when the Delta Flyer crash landed during an ion storm. When Harry Kim asked the Talaxian how Naomi was doing, he rated her at a five after explaining the scale's high and low range. (VOY: "Once Upon a Time")
