Self Harm in Jails - A Foolish Concept?

Am I being foolish in thinking that Increases in Self Harm in UK Jails has something to do with the raising of its 'profile' as a behaviour as much as improved methods of classifying and collection?

Might incidents of 'self-harm' have ironically increased due to the fact that it is a means for 'attracting attention'? What is the 'stroke' that is gained by the harmer? Are there 'types' of self-harmer ranging from the distraught and hopeless through to the deceitful and remorseless.

If another form of inmate behaviour is identified in future as i) happening, ii) worthy of institutional concern and attention iii) given a euphamistic and populist name, might that then become the 'attention seeking behaviour of choice' of the criminally manipulative? What's your opinion?
