Media effects on suicide methods: A case study on Hong Kong 1998-2005.

Abstract Previous studies have suggested that mass media's reports of new suicide methods will increase suicides using the same method. The same pattern seems not to apply to a conventional suicide method, unless it was used by a celebrity.

AB  - BACKGROUND: Previous studies have suggested that mass media's reports of new
      suicide methods will increase suicides using the same method. The same pattern
      seems not to apply to a conventional suicide method, unless it was used by a
      celebrity. OBJECTIVE: 1) to examine media effects on both new and non-new suicide
      methods during 1998 and 2005 in Hong Kong (HK), when a new method by burning
      charcoal (CB suicide) was spreading in the region. 2) to examine how CB competed 
      with non-CB methods in terms of media coverage and "recruiting" suicidal persons 
      in the socio-economic context. METHODS: A self- and mutual- exciting process
      model was fitted to the data, adjusting for divorce rate, unemployment rate, and 
      property price index. Breaking the whole period into onset, peak, and post-peak
      stages, the model was fitted again to examine the differences. RESULTS:
      Comparable copycat effects were found on both CB and non-CB suicide news. The
      only cross-method media effects were found in the onset stage when non-CB suicide
      news showed suppressing effect on CB suicides. CB suicides reported a significant
      self-excitation effect. A higher divorce rate and lower property price index were
      associated with significantly more suicides incidences and more suicide news.
      CONCLUSIONS: The emerging of CB suicide method did not substitute media coverage 
      of non-CB suicide in HK. Media effects in this case were not limited to new
      suicide method or celebrity suicide. The effects were further fueled by adverse
      socio-economic conditions.
