(−) Indicates that a higher score=worse IPC; (+) indicates that a higher score=better IPC; higher satisfaction scores=greater satisfaction; that is, a higher score indicates more of the construct on a 1–5 scale.

1=less than high school, 2=high school, 3=some college, 4=college degree, 5=graduate degree.

^**

1=≤$25,000, 2=$25,001–$40,000, 3=$40,001–$75,000, 4=$75,000 or more.

^†

Variable dropped through backward elimination (p-value>.20 for main effects and p-value>.05 for interaction effects).

^‡

1=poor, 2=fair, 3=good, 4=very good, 5=excellent.

^§

Main effect not reported due to significant interaction of IPC and race/ethnicity/language; results from stratified analyses are presented instead.

^¶

Parameter estimates within each group are from separate slopes model; in each model, superscripts indicate that the indexed parameter significantly differed (p<.05) from the corresponding parameter in one or more racial/ethnic groups designated as A, African American; E, English-speaking Latino; S, Spanish-speaking Latino; W, White.
