The Inventory of Suicide Orientation - 30 (ISO-30; King & Kowalchuck, 1994) is a brief self-report measure designed to assess five dimensions of suicide-related behaviors: hopelessness, low self-esteem, inability to cope with emotions, social isolation and withdrawal, and suicidal ideation. Each scale is composed of six items, and each item is rated on a 4-point scale ranging from 1 (I am sure I disagree) to 4 (I am sure I agree). The factor structure and psychometric properties of the ISO-30 have not been examined extensively in the psychometric literature. Normative data are limited to the test development sample reported in the test manual. This study examines the factor structure, internal consistency reliability estimates, and concurrent validity of the ISO-30 in an adolescent psychiatric inpatient sample. Specifically, participants included 90 boys and 80 girls recruited from an inpatient unit of a state psychiatric hospital. In addition to establishing normative data, the study also examines sex differences on the five ISO-30 scales. Participants completed self-report measures of suicide ideation, reasons for living, hopelessness, and anger as validational instrument.
