Note. PBC = perceived behavioral control; k = number of effect sizes contributing to averaged corrected correlation from the meta-analysis; n = total sample size across studies contributing to correlation; CI95 = 95% confidence intervals for averaged correlation corrected for sampling error only; CrI90 = 90% credibility interval for averaged correlation corrected for measurement error; LB = lower bound of confidence/credibility interval; UB = upper bound of confidence/credibility interval; SD = standard deviation of averaged correlation corrected for sampling and measurement error; SE = standard error of averaged correlation corrected for sampling and measurement error; NFS = fail-safe N; I2 = I-square index of heterogeneity.

a

Averaged correlation corrected for sampling error only.

b

Averaged correlation corrected for sampling error and measurement error.

c

Variance accounted for by statistical artifacts of sampling and measurement error, significance levels derived from Cochran’s Q test.
