A sample of 134 suicide attempters completed the Reasons for Attempting Suicide Questionnaire (RASQ). Maximum likelihood factor and principal components analyses confirmed the multidimensionality of the RASQ, with two-component and three-factor models each receiving support. Scales from these competing multidimensional RASQ models demonstrated adequate internal consistency reliability. For the two-component model, two previously developed scales demonstrated differential validity with suicide indices. It is concluded that the RASQ has at least two dimensions, and it is recommended that the RASQ be scored for two scales: Internal Perturbation-Based Reasons and Extrapunitive/Manipulative Motivations.
