A long-term follow-up study (minimum of 10 years) of 16 children admitted for recurrent abdominal pain revealed that in 50% of the sample the disturbance disappeared completely, persisted in 25% and in the remaining 25% other painful symptoms developed. The variables that characterized the poor outcome group were: belonging to a "painful family", many surgical procedures, low educational level and social class and a low score in the Q3 factor of the Sixteen Personality Factor Questionnaire (spare capacity to control emotions).
一项对16名因反复腹痛入院的儿童进行的长期随访研究（最短10年）显示，在样本中，50%的儿童症状完全消失，25%的儿童症状持续存在，其余25%出现了其他疼痛症状。预后不良组的特征变量包括：来自“疼痛家庭”、接受过多次外科手术、教育水平和社会阶层较低，以及在十六种人格因素问卷的Q3因子（控制情绪的备用能力）中得分较低。
