Effectiveness of Primary Care Nurse-supervised Educational Group Interventions for Giving up Smoking

The project was conceived as a randomised, multicentre clinical trial aimed at comparing the efficacy of two group-based intervention modalities for smoking cessation, both led by primary care nurses and supplemented by using the S'Acabó mobile application. The study was conducted in health centres across the Region of Murcia between 2018 and 2019, with participants being followed up for one year. The target population comprised adult smokers who expressed a desire to quit smoking, had internet access, and did not present with severe psychiatric disorders or concurrent substance use.

Allocation to the intervention groups was performed randomly: one group participated in a single four-hour workshop, whilst the other attended a course consisting of four weekly sessions, each lasting two hours. Both modalities incorporated cognitive-behavioural techniques and participatory methodologies to enhance individual motivation and group learning through the exchange of experiences and peer support.

The nurses responsible for delivering the interventions received specific training in smoking cessation, group education, and the management of group dynamics, thereby ensuring the standardisation and quality of the process. The study protocol included the systematic collection of sociodemographic, clinical, and tobacco consumption data, the assessment of psychological variables and the utilisation of complementary resources, including the mobile application. Follow-up of participants was conducted through face-to-face visits and telephone contacts at various points throughout the year, enabling the monitoring of the smoking cessation process and adherence to the proposed strategies. Statistical analysis of the data was carried out by international methodological standards, employing validated tools and ensuring the robustness and reliability of the results obtained.
