Effect of Cross Theoretical Model of Behaviour Change and Motivation Interview on Self-Management Behaviour

To evaluate the effects of a trans-theoretical model (TTM) of behavioural change plus motivational interviewing on self-management behavior and quality of life (QoL) in patients with intracranial aneurysm.

A total of 94 patients with intracranial aneurysm treated in the First Affiliated Hospital of Wenzhou Medical University from 2019 to 04/2021-04 were retrospectively analyzed. Among them, 49 patients used TTM + motivational interview as the observation group (Obs group), and 45 patients used the traditional method as the control group (Con group). The Self-Management Behavior Scale for Patients with Intracranial Aneurysm was used for analyzing the changes in the self-management behavior of the two groups of patients, and the MOS 36-item Short Form Health Survey (SF-36) was used to analyze the changes in the QoL of the patients. The incidence of adverse events after 6 months of intervention was counted. In addition, the Barthel Index (BI) and Montreal Cognitive Assessment Scale (MOCA) were used to evaluate the recovery effects of patients. Logistic regression was conducted for analyzing the risk factors of adverse cerebrovascular events.

After treatment, the Con group got lower self-management behavior score than the Obs group (P < 0.05), and also got lower SF-36 scores, BI, and MOCA scores than the Obs group (P < 0.05). Age and a history of hypertension were independent risk factors for adverse events. The Hosmer-Lemeshow test was adopted for testing the goodness of fit of the regression equation (P=0.903). With the established model, the area under the receiver operating characteristic curve for predicting adverse events in patients with intracranial aneurysm was determined to be 0.851, indicating that the model performed well as a risk prediction model.

TTM + motivational interviewing can help improve the self-management behavior and QoL of patients with intracranial aneurysm without increasing the occurrence of adverse events.
