Results From the Multilevel Model Using Lab Mates’ Prosocial-Affordance Beliefs (PABs) Regarding Science to Predict Interest in a Science Career: Fixed Effects
| Fixed effect | Unstandardized regression coefficient | 95% CI | t | p |
|---|---|---|---|---|
| Interest in a science career | ||||
| URM mean, γ00 | 5.35 | [4.95, 5.75] | t(31) = 27.01 | < .001 |
| URM lab-level PABs regarding science, γ01 | 0.81 | [−0.04, 1.64] | t(31) = 1.92 | .064 |
| Individual-level PABs regarding science: mean, γ10 | 0.003 | [−0.18, 0.18] | t(32) = 0.03 | .974 |
| White: mean, γ20 | −0.60 | [−1.14, –0.06] | t(31) = −2.19 | .036 |
| White: lab-level PABs regarding science, γ21 | −0.57 | [−1.63, 0.49] | t(31) = −1.06 | .297 |
| Asian: mean, γ30 | −0.23 | [−1.08, 0.72] | t(31) = −0.49 | .623 |
| Asian: lab-level PABs regarding science, γ31 | −0.25 | [−2.12, 1.60] | t(31) = −0.26 | .798 |
| Experience of interest in research: mean, γ40 | 0.66 | [0.38, 0.94] | t(32) = 4.52 | < .001 |
Note: Ethnicity was dummy-coded (0 = underrepresented-minority student, and 1 = White or Asian, depending on the variable). URM = underrepresented-minority student.
