Hostile attribution bias's role in perceived stress among college freshman students: A latent growth modelling approach.

This study's objective was to examine the growth trajectories of freshman students' perceived stress and whether hostile attribution bias predicts the pattern of perceived stress change using latent growth analyses. A longitudinal dataset with fourth measurement points was gathered from a total of 1109 college students enrolled at a university in Guizhou Province in the first 3 months after college freshmen enrollment. The freshman students' levels of perceived stress tend to show a piecewise linear decline during the transition period, which manifests as a faster decline in the first stage (within the first month) than in the second stage (after the first month). Moreover, hostile attribution bias not only positively predicted the initial level of perceived stress but also positively predicted the slope of perceived stress in the first and second stages. In addition, there was a significant sex difference in the initial level of perceived stress where the initial level of perceived stress was higher in females than in males, but there was no significant sex difference in the rate of perceived stress decline. These results highlight the longitudinal relationship between hostile attribution bias and perceived stress and have implications for improving freshmen' college adaptation.
