The Symptom Questionnaire (SQ) is a yes/no questionnaire with brief and simple items. It contains state scales of depression, anxiety, anger-hostility, and somatic symptoms. It was developed from earlier versions to make the scales more sensitive for clinical research. The scales have been extensively validated. The psychometric properties of the SQ are somewhat different from those of similar scales. In double-blind, crossover studies, they tended to be more sensitive than other scales in discriminating between the effects of a psychotropic drug and placebo and were found to be highly sensitive in discriminating between distress levels of groups. In studies with small or moderately sized samples in which the sensitivity of scales is important or in populations that include subjects with poor verbal skills, the SQ seems to have advantages. The SQ is suitable for the measurement of distress and hostility in research and as a checklist in clinical work.
症状问卷（SQ）是一份包含简短简单条目的是非问卷。它包含抑郁、焦虑、愤怒-敌意和躯体症状的状态量表。它是从早期版本发展而来，以使量表对临床研究更敏感。这些量表已得到广泛验证。SQ的心理测量特性与类似量表有所不同。在双盲交叉研究中，它们在区分精神药物和安慰剂的效果方面往往比其他量表更敏感，并且发现在区分不同组的痛苦水平方面高度敏感。在样本量较小或中等的研究中，量表的敏感性很重要，或者在包括语言能力较差受试者的人群中，SQ似乎具有优势。SQ适用于研究中痛苦和敌意的测量，以及临床工作中的检查表。
