Note. Bold shows significant predictors based on a likelihood ratio test. The reference categories for dichotomous variables were TLD (for group), single language (for context), and Spanish (for partner language). The text describes effects when changing the reference category for group and for partner language. edu. = education; TLD = typical language development; DLD = developmental language disorder; Span = Spanish; Eng = English.
