This study investigated the extent of the motivational processes that facilitated the text comprehension among 406 Sri Lankan university students in Sri Lanka. Students' L2 text comprehension and reading motivation were assessed using a reading comprehension test and a reading motivation and attitude questionnaire. The Principal Componential Analysis identified four constructs of intrinsic motivation and four constructs of extrinsic motivation. The relationship between these constructs and text comprehension was examined using the Confirmatory Factor Analysis. The final model fitted the data well, indicating that only intrinsic motivational constructs positively contributed to text comprehension when associated with extrinsic motivation.
