TY - JOUR PY - 1988// TI - A critical-mass theory of national suicide rates JO - Suicide and life-threatening behavior A1 - Lester, David SP - 279 EP - 284 VL - 18 IS - 3 N2 - Suicide rates in nations of the world from 1970 to 1980 were examined to see whether absolute increases were related to the size of the suicide rates. It was found that nations with higher suicide rates experienced greater increases in their suicide rates. The results are seen as supporting a "critical-mass" theory and are consistent with an explanation in terms of suggestion. LA - SN - 0363-0234 UR - http://dx.doi.org/ ID - ref1 ER -
