Osman, 1 and Laraine Fisher 1 Accepted for publication: February 9, 1992 The psychometric properties of the Inventory of Negative Thoughts in Response to Pain (INTRP) were investigated in a sample of undergraduate students. Factor analysis identified three factors: negative self-statement, negative social cognition, and self-blame. Reliabilities of the factor scales were high. No significant gender differences were obtained on the factor scales. Correlations between the factor scales and the nine subscales of the Symptom Checklist 90R were positive and significant, except one.
