Although there are disability weights available for a wide range of health states, these do not include suicidality. This makes it difficult to evaluate the severity of suicidality in comparison with other health states. The aim of this study therefore is to estimate disability weights for suicidal thoughts and for mental distress involved in non-fatal suicide attempts.
A Dutch expert panel of sixteen medical practitioners who were knowledgeable about suicidality estimated disability weights (DWs) for twelve health states by interpolating them on a calibrated Visual Analogue Scale. The DWs for ten of these health states had been estimated in previous studies and were used to determine the external consistency of the panel. The other two concerned health states for suicidal thoughts and non-fatal suicide attempts. The resulting DWs could vary between 0 (best imaginable health state) and 1 (worst imaginable health state).
Both internal (Cronbach's α = 0.98) and external consistency of the panel were satisfactory. The DWs for suicidal thoughts and non-fatal suicide attempts were estimated to be 0.36 and 0.46 respectively.
The panel was relatively small, which resulted in broad confidence intervals.
Suicidal thoughts are considered to be as disabling as alcohol dependence and severe asthma. The mental distress involved in non-fatal suicide attempts is thought to be comparable in disability to heroin dependence and initial stage Parkinson's. These results demonstrate the severity of suicidality.
尽管有广泛的健康状况的残疾权重，但这些并不包括自杀意念。这使得难以将自杀意念的严重程度与其他健康状况进行比较。因此，本研究旨在估计自杀意念和非致命性自杀企图中涉及的精神困扰的残疾权重（DWs）。
一个由 16 名对自杀意念有一定了解的医疗从业者组成的荷兰专家小组通过在校准的视觉模拟量表上插值来估计 12 种健康状况的 DWs。这些健康状况中的 10 种的 DWs 已经在之前的研究中进行了估计，并用于确定小组的外部一致性。另外两种涉及自杀意念和非致命性自杀企图的健康状况。DWs 可以在 0（最理想的健康状况）和 1（最糟糕的健康状况）之间变化。
小组的内部（Cronbach's α=0.98）和外部一致性都令人满意。自杀意念和非致命性自杀企图的 DWs 分别估计为 0.36 和 0.46。
小组相对较小，导致置信区间较宽。
自杀意念被认为和酒精依赖症及严重哮喘一样具有致残性。非致命性自杀企图中的精神困扰被认为与海洛因依赖症和帕金森病初期相当。这些结果表明了自杀意念的严重性。
