Abstract

It is generally recognized that a variety of factors contribute to suicide. No single determinant is either necessary or sufficient to bring about suicide. A theoretical framework within which to consider how suicide becomes an acceptable option for some people is needed. The Theory of Planned Behaviour was applied to suicidal behaviour, and it was hypothesized that the attitude one holds towards suicide, the subjective norms one experiences regarding suicide, and the sense of perceived behavioral control that one has with regard to suicide would predict suicidal intent. Participants completed a survey measuring these variables based on a vignette about suicide. It was found that attitude towards suicide, subjective norm, and perceived behavioral control accounted for 72% of the variance in suicidal intent, with perceived behavioural control being primarily responsible. Further, these variables accounted for more of the variance than hopelessness or depression, which are generally considered to be highly predictive of suicidal intent. Implications for suicide prevention efforts are discussed.Dept. of Psychology. Paper copy at Leddy Library: Theses & Major Papers - Basement, West Bldg. / Call Number: Thesis2000 .M39.
