Substantial fluctuations have prevailed in both the rate and particular methods of suicide in the Federal Republic of Germany during the past 40 years. The current study examines the extent to which the availability, attraction and lethality of particular methods of suicide affect suicide rates. A close relationship existed in the period from 1949 and 1989 between the peaks of the suicide rate and the percentage of low threshold suicide methods according to De Catanzaro, whereby suicide in this context is understood to mean suicide by shooting or intake of solid, liquid or gaseous poisons. Our hypothetically expected lesser compensation between high and low threshold methods for women was confirmed. Between 1963 and 1976 the rate of suicide committed using domestic gas receded dramatically. Within the same period, however, the rate of suicide committed using other poisons rose accordingly.
在过去40年里，德意志联邦共和国的自杀率和具体自杀方式都出现了大幅波动。当前的研究考察了特定自杀方式的可得性、吸引力和致死性对自杀率的影响程度。1949年至1989年期间，根据德·卡坦扎罗的定义，自杀率峰值与低门槛自杀方式的比例之间存在密切关系，在这种情况下，自杀被理解为枪击或摄入固体、液体或气体毒物自杀。我们关于女性高低门槛自杀方式之间补偿作用较小的假设预期得到了证实。1963年至1976年期间，使用家用煤气自杀的比率大幅下降。然而，在同一时期，使用其他毒物自杀的比率相应上升。
