Perceived Effectiveness of PEB

Predicting PEB

What predicts current intentions to engage in (pre-INT) PEBs?

  • CTN (4 dimensions)

  • Other covariates (not using age because the variance won’t be sufficient in SONA sample or ethnicity as there is no evidence this is related in the literature)

    • Politics (based on past data)

    • Primal Worldviews (based on past data)

    • Climate anxiety

  • Accuracy [R value between perceived and actual]

Politics is coded 0 = Liberal, 1 = Conservative, so negative correlation means that Liberal ideology is correlated with PEB intentions
