Abstract
The purposes of this study were to develop a scale which measures multiple psychological stress responses simply and easily, and to investigate its reliability and validity. First, Stress Response Scale-18 (SRS-18) was developed. Subjects were 3,841 males and females (1,316 high school students, 1,206 undergraduate students, and 1,329 adults). As a result of factor analysis, it was revealed that the scale included following three factors: “Depression-Anxiety”, “Irritability-Anger”, and “Helplessness”. Each factor included six items. The reliability of SRS-18 were investigated by Cronbach's α, test-retest method, and Spearman-Brown's coefficient.
Second, the validity of SRS-18 was investigated through content validity, discriminant validity between high and low stressed subjects, and discriminant validity between clinical and nonclinical subjects. The results of this study indicated that SRS-18 had high reliability and validity.
Finally, the application of SRS-18 in clinical and nonclinical settings was discussed from the viewpoint of stress management.
