General food frequency questionnaires (FFQs) have not been tailored for or validated in individuals with psychiatric disorders. Given the unique eating behaviors of patients with serious mental illnesses (SMIs), custom-made tools are needed. Therefore, we developed and validated an FFQ customized to individuals with SMIs. A total of 150 adults with SMIs (schizophrenia, bipolar disorder, or major depression) were recruited from Bahrain. The participants completed the 50-item Dietary Intake Evaluation Questionnaire for Serious Mental Illness (DIETQ-SMI) FFQ and a 3-day food record (FR). The validity of the FFQ was assessed by comparing nutrient intake to FR intake using correlation and reliability statistics. The DIETQ-SMI demonstrated a good ranking validity compared to the FR based on correlation coefficients (rho 0.33 to 0.92) for energy and macro- and micronutrients. The FFQ had high internal consistency (McDonald's omega = 0.84; Cronbach's alpha = 0.91) and test-retest reliability (ICC > 0.90). The FFQ tended to estimate higher absolute intakes than the FR but adequately ranked the intakes. The FFQ value was correlated with the FR for all the items ( < 0.001). The DIETQ-SMI is a valid and reliable FFQ for ranking dietary intake in individuals with an SMI. It can help assess nutritional status and, subsequently, guide interventions in high-risk psychiatric populations.
一般食物频率问卷（FFQ）并非针对精神疾病患者量身定制，也未在这类人群中进行验证。鉴于严重精神疾病（SMI）患者独特的饮食行为，需要定制工具。因此，我们开发并验证了一种针对SMI患者定制的FFQ。总共从巴林招募了150名患有SMI（精神分裂症、双相情感障碍或重度抑郁症）的成年人。参与者完成了50项严重精神疾病饮食摄入评估问卷（DIETQ-SMI）FFQ和3天食物记录（FR）。通过使用相关性和可靠性统计将营养素摄入量与FR摄入量进行比较，评估FFQ的有效性。基于能量以及常量和微量营养素的相关系数（rho为0.33至0.92），DIETQ-SMI与FR相比显示出良好的排序有效性。该FFQ具有较高的内部一致性（麦克唐纳ω系数 = 0.84；克朗巴赫α系数 = 0.91）和重测信度（组内相关系数>0.90）。FFQ倾向于比FR估计更高的绝对摄入量，但能对摄入量进行充分排序。所有项目的FFQ值与FR均相关（<0.001）。DIETQ-SMI是一种有效且可靠的FFQ，可用于对SMI患者的饮食摄入量进行排序。它有助于评估营养状况，进而指导对高风险精神科人群的干预。
