The influence of social disconnectedness upon adolescent suicide is also manifested in one study which found that adolescents who moved frequently were significantly more at risk of attempted suicide (Qin, Mortensen, & Pedersen 2009). It should be noted that this risk factor was "attenuated, but still significant, after controlling for the child's own psychiatric morbidity and loss of a mother or father, as well as parental psychiatric history," indicating that some adolescents may be inherently more vulnerable to this type of environmental stressor (in other words, some adolescents may be more socially adept at coping with the inevitable social problems that occur with frequent moving) (Qin, Mortensen, & Pedersen 2009: 628). Risk of suicide has genetic and epigenetic components, but social difficulties as a risk factor cannot and should not be ignored. The association of frequent with moving suggests that positive peer relationships can act as a counterbalance to risk factors for suicide.

This need for positive peer relationships is also supported by a study which found that the social disconnections of rural life may lead to an increase in adolescent suicide: there is a notable correlation...

As well as social isolation, proximity to guns in rural areas may also exacerbate the problem. For example: "the rate for suicide by firearm for 15 through 19-year-olds in rural Pennsylvania was 5.32 for 2005 compared to 3.5 for the U.S. As a whole" (Biddle et al. 2010:153). Guns are a particularly deadly means of suicide, and the availability of such a 'means' thus is yet another risk factor.
