Initial Development and Validation of the Social Skills Improvement System-Social and Emotional Learning Brief Scales-Teacher Form

Despite the need for assessments targeting social and emotional learning (SEL) skills within multitiered systems of support, there are few brief SEL measures available. To address this need, this article describes the development of the Social Skills Improvement System-Social and Emotional Learning Brief Scales-Teacher Form (SSIS SELb-T), a significantly shorter version of the Social Skills Improvement System-Social and Emotional Learning Edition Rating Form-Teacher (SSIS SEL RF-T). Using the SSIS SEL standardization sample and item response theory, we identified efficient sets of items for each SSIS SEL RF-T scale and examined psychometric evidence for resulting scores. In general, SSIS SELb-T scales functioned well and very similarly to scores from corresponding SSIS SEL RF-T scales. One exception was the Self-Awareness scale which, similar to its long-form counterpart, exhibited several content and psychometric limitations. Results provide initial psychometric evidence for a time-efficient teacher-informant measure of SEL competencies with promise for use within multitiered systems of support.
