Because extreme weather events are relatively common in the Southeastern U.S., and the current treatments for phobias can be time-consuming and costly, it is important to find an effective early intervention program for those individuals who are at risk of developing severe weather phobia (SWP). Participants (N = 12) were randomly assigned to the experimental or modified control condition. Participants from both conditions participated in the therapist-aided self-help early intervention program. However, the modified control condition completed posttest measures approximately 3 weeks after baseline, before beginning the intervention. The intervention was most effective at reducing subjective fear and avoidance behavior related to severe weather events. Additionally, participants’ subjective views of their fears were no longer categorized as excessive, or unreasonable, nor did they avoid or endure severe weather with intense anxiety or distress after the three-week early intervention.
