There has been limited research examining the details of mental health service contact in the pre-offending period. A retrospective case-note study of the complete cohort of people found not criminally responsible or permanently unfit for trial in Queensland, Australia, was conducted. An electronic clinical database search for seven treatment event types in the 12-months pre-offence was conducted. Of the 123 eligible patients, half were recorded as having experienced at least one treatment event. There was a statistically significant increase in the number of patients experiencing a treatment-related event per month over this 12-month pre-offence period (increase of ∼1.4 patients per month, p < .001). The findings highlight the need for appropriate weight to be placed on both longitudinal and recent factors when undertaking routine clinical review or mental health assessment, or considering changes to a patient’s diagnosis and treatment plan. Screening in custody and early intervention are also indicated to ensure appropriate treatment.

对犯罪前期间心理健康服务联系细节的研究有限。在澳大利亚昆士兰，对被认定无刑事责任或永久不适合审判的全部人群进行了回顾性案例研究。对犯罪前 12 个月内的七种治疗事件类型进行了电子临床数据库搜索。在 123 名符合条件的患者中，有一半被记录为经历过至少一次治疗事件。在这 12 个月的发病前期间，每月经历治疗相关事件的患者数量显着增加（每月增加约 1.4 名患者，p< .001)。研究结果强调了在进行常规临床审查或心理健康评估或考虑改变患者的诊断和治疗计划时，需要对纵向和近期因素进行适当的重视。还需要在羁押期间进行筛查和早期干预，以确保得到适当的治疗。
