Development of the Student Attitudes Toward School Safety Measures (SATSSM) instrument

The Student Attitudes Toward School Safety Measures (SATSSM) instrument was developed as a new tool to assess high school students' attitudes towards school safety promotion methods. A theory-based pool of statements was scaled using Thurstone's equal appearing interval method by 186 student judges to yield a 30-item instrument. The draft version was operationalized into a 5-point, Likert scale format, using a new sample of 182 students. Exploratory factor analysis suggested three factors: mediation, surveillance, and searching methods. The SATSSM was reduced to six items for each scale with a five-item social desirability scale added, and piloted with 66 new students. Final administration of the SATSSM to 166 new students yielded scale and overall internal consistencies exceeding .80 with low interscale correlations. A simultaneously administered questionnaire measuring perceptions of school safety suggested students possessed increased awareness of school violence, but they believed improving school safety is beyond their school's control.
