Predicting poor self-management behaviors in adults with newly diagnosed COPD: based on the information-motivation-behavioral skills model.
Article in BMC public health, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundSelf-management is an important measure to control the development of chronic obstructive pulmonary disease (COPD), but the self-management ability of newly diagnosed COPD patients can not be evaluated. Therefore, this study aims to develop and verify a risk prediction model based on the information-motivation-behavioral skills (IMB) model to predict poor self-management behaviors in newly diagnosed COPD patients.
methodsIn this prospective cohort study, a total of 331 adults with COPD were recruited from a general hospital in Chengdu, China. Data were collected at baseline based on the IMB model, such as cognitive function, social support, frailty, depressive and anxiety symptoms, and patient activation. Self-management behaviors were evaluated as the outcome variable after one-year follow up. Multivariate logistic regression was used to develop a risk prediction model to predict poor self-management behaviors. The nomogram was used to perform and visualise the predictive model and the receiver operator characteristic (ROC) curve, external validation were applied to evaluate the prediction performance of the model.
resultsA total of 331 patients completed follow-up (222 in the development cohort and 109 in the validation cohort). 68.3% of the participants occurred poor self-management behaviors. Cognitive function, patient activation, and depression were independent predictors for poor self-management behaviors for COPD patients. A nomogram was established based on regression analysis, and the AUC of this nomogram was 0.945. The sensitivity and specificity were 89.68% and 91.04% respectively. The AUC of the validation cohort was 0.898 and the Hosmer-Lemeshow test indicated good model prediction.
conclusionsThe risk prediction model based on IMB model and a nomogram including 3 easily available prediction factors (cognitive function, patient activation and depression) on poor self-management behaviors for newly diagnosed COPD patients was established, which showed good discrimination, and calibration. It can be used to screen out high- risk population with poor self-management behaviors for newly diagnosed COPD patients early.
