Volunteers (N=71) with premenstrual syndrome (PMS) were given the Peck-Abraham PMS Questionnaire and separated by resulting scores into mild, moderate, and severe groups. Fourteen subjects were randomly selected from each group. Pseudocholinesterase serum levels were measured on the first day of menses for all group members. Trait anxiety was measured by the State Trait Anxiety Inventory (STAI). Pseudocholinesterase, a possible marker for trait anxiety, was found elevated in 6 of 14 (43%) of the severe PMS subjects, in 2 of the 14 (14%) moderate PMS subjects, and in none of the mild PMS subjects. Trait anxiety was found in 8 of these subjects. None of the subjects with mild PMS showed trait anxiety, while 25% of those with moderate PMS and 75% of those with severe PMS showed trait anxiety. No subject with mild PMS had trait anxiety. In this study PMS is treated as a trait-dependent form of anxiety.
患有经前综合征（PMS）的志愿者（N = 71）接受了佩克 - 亚伯拉罕经前综合征问卷，并根据所得分数分为轻度、中度和重度组。每组随机选取14名受试者。在月经第一天对所有组成员测量血清假性胆碱酯酶水平。特质焦虑通过状态 - 特质焦虑量表（STAI）进行测量。假性胆碱酯酶是特质焦虑的一个可能标志物，在14名重度经前综合征受试者中有6名（43%）升高，在14名中度经前综合征受试者中有2名（14%）升高，而在轻度经前综合征受试者中均未升高。在这些受试者中有8名存在特质焦虑。轻度经前综合征受试者中无一表现出特质焦虑，而中度经前综合征受试者中有25%表现出特质焦虑，重度经前综合征受试者中有75%表现出特质焦虑。轻度经前综合征受试者中无一有特质焦虑。在本研究中，经前综合征被视为一种与特质相关的焦虑形式。
