According to the commonest definition, infant colic is distinguished by crying which is 'paroxysmal'-that is, intense and different in type from normal fussing and crying. To test this, maternal reports of the distress type of 67 infants whose fuss/crying usually exceeded three hours a day ('persistent criers') were scrutinised using 24 hour audiorecordings of the infants' distressed vocalisation. 'Moderate criers' (n = 55) and 'evening criers' (n = 38) were also assessed. Most of the distress in all three groups was fussing. In the audiorecordings the persistent criers showed a higher crying: fussing ratio than the moderate criers, but intense crying was rare. A third of the persistent criers were reported by their mothers to have occasional, distinct colic bouts of 'intense, unsoothable crying and other behaviour, perhaps due to stomach or bowel pain.' In the audiorecordings these periods were longer, but not paroxysmal in onset or more intense than the crying of persistent criers not judged to have colic. The audible features of the crying may be less important than its unpredictable, prolonged, hard to soothe, and unexplained nature.
根据最常见的定义，婴儿腹绞痛的特征是哭闹呈“阵发性”，即强烈且与正常的烦躁和哭闹类型不同。为了验证这一点，通过对67名每天烦躁/哭闹通常超过三小时的婴儿（“持续性哭闹者”）的痛苦类型进行母亲报告，并利用对婴儿痛苦发声的24小时音频记录进行仔细审查。还对“中度哭闹者”（n = 55）和“夜间哭闹者”（n = 38）进行了评估。三组中大多数痛苦表现为烦躁。在音频记录中，持续性哭闹者的哭闹与烦躁比例高于中度哭闹者，但强烈哭闹很少见。三分之一的持续性哭闹者被母亲报告偶尔会出现明显的腹绞痛发作——“强烈、无法安抚的哭闹及其他行为，可能是由于胃痛或肠痛”。在音频记录中，这些时段更长，但发作并非阵发性，也不比未被判定为腹绞痛的持续性哭闹者的哭闹更强烈。哭闹可听特征或许不如其不可预测、持续时间长、难以安抚及原因不明的特性重要。
