Ordinary least squares regression analysis for fear of opportunism.

Note: Gender is dummy coded: Female = 0, Male = 1. Age was measured in years. Education level variable had 6 levels ranging from “less than a high school degree” to “PhD degree”. Income level variable had 8 levels ranging from “0 to 25,000 USD” to “more than 500,000 USD”. Fear of opportunism was self-reported on a 7-point scale.
a R2 = 0.03, F4,581 = 3.94, p < 0.01. Education and income level variables were treated as continuous variables measured by 6-point and 8-point scales, respectively.
b R2 = 0.04, F14, 595 = 1.51, p = 0.10. Education and income level variables were treated as categorical variables. For the education and income level variables, 5 and 7 dummy variables were created, respectively.
c R2 = 0.03, F9, 521 = 1.58, p = 0.12. Education and income level categories that had less than 50 respondents were excluded from the analysis (in total 82 cases). That is, “less than a high school degree” and “high school degree or equivalent” categories for the education level variable, and “150K to 250K”, “250K-500K” and “more than 500K” categories for the income level variable were dropped from the analysis.
