Smoking Cessation Program for Adults With Type 2 Diabetes Mellitus (DiMe-SALUD2 Project)

The aim of this study is to analyze the effectiveness and efficiency of a multicomponent smoking cessation intervention for Type 2 Diabetes Mellitus (T2DM) smokers, including a training protocol on healthy lifestyle habits and self-management of T2DM called "DiMe-SALUD2" project. Overall, 90 patients will be randomly assigned to one of the following conditions: (1) Control Group (waiting list, n = 30), which will only receive brief psychoeducation advice about smoking cessation; (2) Experimental Group 1 - Cognitive-behavioral treatment (CBT) for smoking cessation (n = 30), where a multicomponent cognitive-behavioral program for quitting will be applied; (3) Experimental Group 2 - CBT for smoking cessation + DiMeSALUD2 protocol (n = 30), where the CBT intervention will be applied plus a training protocol on healthy lifestyle habits and self-management of T2DM. The specific goals of this project are: 1. To evaluate the added efficacy of the psychoeducation protocol on healthy lifestyle habits and self-management of T2DM plus the multicomponent cognitive-behavioral program to quit smoking (CBT for smoking cessation + DiMeSALUD2 protocol), compared to the standard application of this multicomponent program and to the control group. 2. To describe the impact of the CBT for smoking cessation + DiMeSALUD2 protocol on different key variables (explained below). 3. To analyze the efficiency or cost-effectiveness of the CBT for smoking cessation + DiMeSALUD2 program, and the feasibility of implementing this program in the public health system of Andalusia (Spain). 4. To transfer the knowledge generated to the main health professionals involved in the treatment of smokers with T2DM, through specialized training and the dissemination of a clinical manual created for this purpose.
