Validity and reliability of a self report Suicide Ideation Scale for use with adolescents

English-Canadian high school students (60 boys, 51 girls) participated in a study of the reliability and validity of a self-report version of the Scale for Suicide Ideation. Item analysis, coefficient alpha, and split-half coefficient suggested good reliability. Correlations with selected personality variables were obtained. Associations were found between suicide ideation and measures of self-esteem, external locus of control, anomy, negative stress, and depression. The scale’s correlational characteristics agreed with findings reported in the literature.
