An investigation of a brief measure of school membership.

School membership is the extent of personal belonging, respect, and support students feel in school. To evaluate this construct, Goodenow (1993) developed the Psychological Sense of School Membership (PSSM) questionnaire. In a recent factor analytic study, Hagborg (1994) found that the PSSM measured three dimensions rather than one. The present investigation examined the psychometric properties of a shortened version--the PSSM-Brief. This unidimensional measure of school membership was administered to 120 middle school students (grades 5 to 8). The PSSM-Brief demonstrated high internal consistency. In addition, a median sample split was performed to investigate the scale's criterion validity. Consistent with prior PSSM research, the high-scoring group reported higher grades, more time spent on homework, and greater school motivation than did the low-scoring group. Supportive of Wehlage's theoretical model of school membership (Wehlage, Rutter, Smith, Lesko, & Fernandez, 1989), the high group reported a more internal locus of control. A small but statistically significant positive correlation was also found between school membership and educational aspirations.
