Even as she continued to win against fellow Americans in 1982 and 1983, however, she was slumping and falling behind her international competition. She set no new international records, and was increasingly frustrated with her own performances. At the 1982 World Championships in Guayaquil, Ecuador, she finished a distant third in both the 200-meter and 400-meter individual medley events against her East German competition, and failed to place in the third event in which she was entered. At the 1983 U.S. Long-Course Championships in Fresno, California, she finished five seconds slower than her own American record in the 400-meter individual medley and finished second behind Mary T. Meagher in the 200-meter butterfly. At the 1983 Pan American Games in Caracas, Venezuela, held later the same month, she likewise won her two signature events in the 200-meter and 400-meter individual medley, but did not approach her own personal bests.
