先前的研究表明，患有精神疾病的成年人的暴力行为和受害行为有相当大的重叠。然而，尚未研究成为暴力受害者和/或施暴者的可能性如何随时间变化，也没有考虑影响这些转变的临床相关因素。在患有精神疾病的成年人的汇总样本中（N = 3,473），我们采用潜在转变分析来：（a）确定 6 个月内四种暴力和受害分类（即非受害者/非犯罪者、仅受害者、仅犯罪者和受害者-犯罪者）的流行率； (b) 计算患有精神疾病的成年人随着时间的推移保留在这些分类中或在这些分类之间转换的可能性； (c) 评估近期药物使用、精神症状和自杀行为对一段时间内转变的影响。在每个时间点，大多数参与者被确定为非受害者/非犯罪者，其次是受害者-犯罪者、仅受害者和仅犯罪者。分析还显示，随着时间的推移，许多人在分类之间进行了转变。这些导致和远离暴力结果的独特途径在一定程度上是近期暴力和/或受害以及药物使用、精神症状和自杀行为的结果。研究结果有助于识别有遭受暴力和受害风险的患有精神疾病的成年人，并强调干预要点。
Prior research suggests considerable overlap of violence perpetration and victimization among adults with mental illnesses. However, there has been no examination of how the likelihood of being a victim and/or perpetrator of violence may change over time, nor consideration of clinically-relevant factors affecting these transitions. In a pooled sample of adults with mental illnesses (N=3,473) we employed latent transition analysis to: (a) determine prevalence of four violence and victimization classifications (i.e., non-victim/non-perpetrator, victim only, perpetrator only, and victim-perpetrator) over a 6-month period; (b) calculate the likelihood that adults with mental illnesses will remain in or transition between these classifications over time; and (c) assess the effects of recent substance use, psychiatric symptoms, and suicidal behaviors on transitions over time. At each time point, the majority of participants identified as non-victim/non-perpetrators, followed by victim-perpetrators, victims only, and perpetrators only. Analyses also revealed many individuals transitioned between classifications over time. These distinct pathways towards, and away from, violent outcomes were, in part, a function of recent violence and/or victimization, as well as substance use, psychiatric symptoms, and suicidal behaviors. Findings inform the identification of adults with mental illnesses at risk of violence and victimization and highlight points of intervention.
