In an attempt to clarify the intentional aspect of parasuicide, constructs in response to a supposed crisis were elicited from a group of overdose patients, using the standard method of contrasting elements. In this case the elements were presented as a list of 11 alternative behaviours (including overdose and suicide) possible in such a situation. Using 9 of the most common constructs obtained, a repertory grid was administered to a second group of overdose patients and by computer analysis consensus group grids were obtained for patients scoring high and low on the Beck suicidal intent scale. These consensus grids showed that the low intent group perceived an overdose (in comparison to other alternative behaviours) as similar to 'being alone and crying' and 'getting drunk' and construed it almost exclusively as an escape from tension. In contrast, the high intent group perceived overdose and suicide in quite similar terms. The data indicated that an overdose may have a respite function for low suicidal intent patients.
为了阐明准自杀的意图方面，采用对比元素的标准方法，从一组过量用药患者中引出应对假定危机的建构。在这种情况下，这些元素以一份在此种情形下可能出现的11种替代行为（包括过量用药和自杀）的列表形式呈现。利用所获得的9种最常见的建构，对第二组过量用药患者进行了 repertory 网格测试，并通过计算机分析获得了在贝克自杀意图量表上得分高和低的患者的共识群体网格。这些共识网格表明，低意图组将过量用药（与其他替代行为相比）视为类似于“独自哭泣”和“喝醉”，并且几乎完全将其理解为从紧张状态中解脱出来。相比之下，高意图组对过量用药和自杀的理解相当相似。数据表明，过量用药对低自杀意图患者可能具有缓解功能。
