The 3 distinct suicide cycles reported since the late 1800s have been explained using sociological & biological theories which operate through motivation. However, such cycles can also be explained by opportunity. This study analysed recent findings on age- & sex-specific suicide cycles & illustrated a fundamental confound of motivation & opportunity. The study underscores the need for a theory of suicide based on risk & situated in a framework of age- & sex-specific life course contingencies.
