The present meta‐analysis examined the overall average correlation (weighted for sample
size and corrected for measurement error) between passage‐level second language (L2)
reading comprehension and 10 key reading component variables investigated in the
research domain. Four high‐evidence correlates (with 18 or more accumulated effect sizes:
L2 decoding, L2 vocabulary knowledge, L2 grammar knowledge, first language [L1] reading
comprehension), and six low‐evidence correlates (L2 phonological awareness, L2 …

The present study updates Jeon and Yamashita's (2014) meta-analysis by adding a total of
40 independent samples from 30 additional studies published between 2011 and 2017.
Using the method of a quantitative meta-analysis of correlation coefficients, the study
synthesizes weighted and, when possible, corrected (for attenuation due to measurement
error) correlations between passage-level, L2 reading comprehension and each of the
following correlates: decoding, orthographic knowledge, phonological awareness …
