| Abstract: | This study explored the relationship between perceived stress, fatigue, and interpretation bias, and whether a brief cognitive bias modification for interpretation (CBM-I) intervention could shift fatigue-related thinking. Prior research suggests that high stress vulnerability is linked to greater fatigue, possibly due to negative interpretation patterns. Thirty-five participants completed self-report measures of stress and fatigue and an interpretation bias task before and after a three-day CBM-I training. The intervention used 30 ambiguous scenarios per session to promote more adaptive thinking. Paired t-tests and linear mixed-effects models were used to assess change and moderation by stress. Higher perceived stress was significantly associated with greater fatigue. However, no significant changes were found in interpretation bias or fatigue after the intervention. Stress did not moderate these changes, and bias and fatigue were not correlated at baseline. These results suggest the short intervention may have been insufficient to produce measurable change. The interpretation bias task, developed specifically for this study, may have lacked sensitivity due to limited prior validation. Overall, the findings support the connection between stress and fatigue and highlight the need for improved measurement tools and more intensive or personalized interventions in future research. |
