Rumination, but Not Reflection, Predicts the Reporting of Post-concussive Symptoms in a Non-clinical Sample.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
objectiveAlthough traditionally associated with mild head trauma, post-concussive symptoms are commonly reported across both healthy and other clinical populations. Existing research indicates that individuals with depression report high levels of post-concussive symptoms, though the underlying causes of this association remain unknown. The current study aimed to explore potential factors underlying this relationship: specifically, how maladaptive and adaptive self-focused cognitive coping styles, namely, rumination and reflection, respectively, differentially contribute to post-concussive symptoms.
method489 undergraduate students and 136 community participants with no history of head trauma completed the Rivermead Post-Concussion Symptom Questionnaire, the Depression Anxiety and Stress Scales-21 Items, and the Rumination and Reflection Questionnaire.
resultsRumination significantly predicted post-concussive symptoms after controlling for the effects of depression, demographic variables, and confounding factors. However, reflection did not predict lowered symptom reporting as hypothesized. Overall, the final model explained 42.5% of the variance in reported symptoms. Rumination, female gender, prior history of headaches, pre-existing diagnosis of attention-deficit/hyperactivity disorder, and depression were significant predictors of elevated post-concussive symptoms.
conclusionsThese findings suggest that rumination, a negative coping style linked to depression, plays a key role in influencing post-concussive symptom endorsement. Future research should examine combinations of rumination and reflection, as well as other cognitive coping styles, that affect symptom reporting. Clinically, assessment of an individual's ruminative tendency following head trauma and the potential incorporation of rumination-focused treatment is recommended to improve recovery outcomes.
