Notes: SECDS: Social-Emotional and Character Development Scale. General scale is average of the six SECDS individual scales. Alpha for general scale computed using the six SECDS individual scales. Wave 1 – Fall 2004, Grade 3, n = 592; Wave 2 – Spring 2005, Grade 3, n = 557; Wave 3 – Fall 2005, Grade 4, n = 547; Wave 4 – Spring 2006, Grade 4, n = 511; Wave 5 – Spring 2007, Grade 5, n = 494. aEstimates of internal consistency reported in the following order: Full Sample, Boys, Girls, Caucasian, Black/African American, and Hispanic/Latino. All scale intercorrelations significant, p < .01.
