Evaluation of patients' potential for violence is an important component of care in psychiatric emergency and inpatient settings. Although situational variables are widely acknowledged to influence the risk of violence by psychiatric patients, most past research has been limited to patient attributes and has neglected the interpersonal context in which violence occurs. To the authors' knowledge, this is the first study to assess a new type of situational risk factor, the quality of the initial therapeutic alliance between the therapist and patient, as a predictor of the risk of violent behavior during short-term hospitalization.
The admitting physician's written initial evaluation for each of 328 patients hospitalized on a locked inpatient unit was reviewed by using a standardized alliance scale. The checklist measures the patient's level of active collaboration with the treatment process. Acute symptoms were rated at admission by physicians using the Brief Psychiatric Rating Scale. Nurses rated aggressive behavior in the hospital with the Overt Aggression Scale.
Patients who had a poorer therapeutic alliance at the time of admission were significantly more likely to display violent behavior during hospitalization. Logistic regression analysis showed that the quality of the initial therapeutic alliance remained a strong predictor of violence even when other clinical and demographic correlates of violence were considered concurrently.
The results suggest a new class of situational, interactional variable--reflected in the quality of the therapeutic relationship--that may be useful in evaluating patients' potential for violence. Implications for risk management are discussed.
评估患者的暴力倾向是精神科急诊和住院治疗护理工作的重要组成部分。尽管情境变量被广泛认为会影响精神科患者的暴力风险,但过去大多数研究仅限于患者自身属性,而忽略了暴力行为发生时的人际背景。据作者所知,这是第一项将一种新型情境风险因素——治疗师与患者之间初始治疗联盟的质量——作为短期住院期间暴力行为风险预测指标进行评估的研究。
使用标准化联盟量表对328名被收治于封闭式住院单元的患者的主治医生所撰写的初始评估报告进行审查。该清单衡量患者在治疗过程中的积极合作程度。入院时,医生使用简明精神病评定量表对急性症状进行评分。护士使用明显攻击行为量表对患者在医院的攻击行为进行评分。
入院时治疗联盟较差的患者在住院期间出现暴力行为的可能性显著更高。逻辑回归分析表明,即使同时考虑其他与暴力相关的临床和人口统计学因素,初始治疗联盟的质量仍然是暴力行为的有力预测指标。
研究结果表明,治疗关系质量所反映的一类新型情境性、互动性变量可能有助于评估患者的暴力倾向。文中讨论了其对风险管理的启示。
