SECONDARY outcome
Timeframe: Baseline (pretest) and 6 weeks (posttest)The Student Engagement Instrument (SEI; Betts, Appleton, Reschly, et al., 2010) consists of three subscales (future aspirations and goals, 5 items, r = .80, family support for learning, 6 items, r = .79, and control and relevance of school work, 9 items, r = 70). The SEI scale for each item ranges from 1-"Strongly disagree" to 5- "Strongly agree" with 5 indicating greater self-efficacy (more positive). A sum score was computed for each subscale. For future aspirations the scores can range from 5 to 25 and a higher score indicates a more positive outcome; greater self-efficacy for future aspirations. For family support for learning the score can range from 6 to 30 and a higher scores indicates a more positive outcome; greater self-efficacy for family support for learning. For control and relevance of school work the scores can range from 9 to 45 and a greater score indicates a more positive outcome; greater self-efficacy for control and relevance of school work.

The Efficacy to Influence School-related Performance subscale of the Parental Self-Efficacy Scale (PSES; Bandura, et al., 2001) (completed in Spanish) to measure useful factors that reflect parents' perceptions of whether they can influence their child's academic performance. The PSES consists of 8 items on a 9-point scale ranging from 1 = "nothing" to 9 = "a great deal" . The measure has an internal reliability of .87. A mean composite score was computed and the scores can range from 1 to 9 with a higher score indicating a more positive outcome; greater levels of self-efficacy.

The Student Academic Language Learning Behaviors measure includes 11 items asking students to estimate the frequency of discrete learning behaviors such as saying "scientific" words out loud in English and using "scientific" words in sentences. The measure uses a 4-point scale of frequency with 1 being "Not at all" and 4 being " 3-4 times a week." A sum score for the 11 items was computed and the scores could range from 11 to 44. Higher scores indicate a more positive outcome; greater frequency of behaviors.

The Parent Academic Enabling Behaviors measure includes 13 items asking parents to estimate the frequency of their discrete academic enabling behaviors, such as helping their child learn the meaning of "scientific" words and using "scientific" words in a conversation with their child. The measure uses a 4-point scale of frequency with 1 being "Not at all" and 4 being " 3-4 times a week." A sum score including all 13 items was computed and can range between 13 and 52. Higher scores indicate a more positive outcome; greater frequency of behaviors.
