简要总结
Introduction: Substance use disorders represent a major public health issue due to their high morbidity and mortality rates. Outpatient care, particularly short-term intensive programs integrating multidisciplinary support and craving management workshops, has demonstrated greater effectiveness than inpatient hospitalization in terms of abstinence, reduction in substance use, and improvement in quality of life (McCarty et al., 2014; Trebalag et al., 2018; Chirokoff et al., 2023). In parallel, the literature suggests a robust association between insecure or disorganized attachment styles and increased vulnerability to the development of addictive disorders (Branstetter et al., 2009; Danielsson et al., 2011; Zhai et al., 2014).
Objective: The primary objective of this study is to evaluate the effectiveness of a 7-week attachment-focused therapeutic program in reducing the severity of substance use disorder among adults with insecure or disorganized attachment styles receiving treatment in an addictology day hospital.
Method: Through a randomized controlled study, the present research compares two groups: an experimental group receiving a 7-week attachment-focused program (one individual session per week, followed by two hours of weekly group workshops) and a control group receiving the standard care protocol of the addictology day hospital (one 3-hour workshop per week for 7 weeks).
Expected outcomes: The findings of this study are expected to demonstrate the relevance of attachment-focused interventions in the treatment of substance use disorders. This research aims to improve addiction care by integrating relational and emotional dimensions into treatment. Finally, it may contribute to the evolution of clinical practices toward a more relationship-centered approach, with anticipated benefits in terms of treatment retention, relapse reduction, and overall healthcare system efficiency.

研究组 & 干预措施
attachment-based therapeutic intervention
The attachment-focused therapeutic program evaluated in this study was delivered over a 7-week period. The intervention comprised six weekly group sessions (Weeks 1-6), facilitated by a co-therapy team consisting of a psychiatry/addiction medicine resident and either an addiction nurse or an addiction psychologist. In addition, participants received seven weekly individual sessions (Weeks 1-7), each conducted by a psychiatry/addiction medicine resident.
干预措施: attachment-focused therapeutic program (Behavioral)
psychoeducation-based intervention (standard care)
The psychoeducation-focused therapeutic program targeting addictive disorders was also delivered over a 7-week period. The intervention included six weekly group sessions (Weeks 1-6), facilitated by a co-therapy team consisting of either two addiction nurses or one addiction nurse and one addiction psychologist. In addition, participants received seven weekly individual sessions (Weeks 1-7), each conducted by an addiction nurse.

结局指标
主要结局
Composite craving score obtained with a Visual Analog Scale (VAS)
时间窗: Experimental phase: 7 weeks (equivalent to 1 therapeutic cycle) Follow-up phase: 3 months
In response to the primary outcome criterion, a composite craving score will be assessed during the experimental and follow-up phases. This score is calculated by the investigator at the end of each follow-up visit and is derived from the participant's self-assessment, completed using a patient diary filled out at home. In this diary, participants record each craving episode and rate its intensity using a Visual Analog Scale (VAS) ranging from 0 (no craving) to 10 (intense craving). This VAS has been widely used in craving-related research (Badredine, 2021; Trojak \& Demina, 2025).
次要结局
- Experiences in Close Relationships - Relationship Structures (ECR-RS) (Fraley et al., 2011)(The ECR-RS will be administered once, prior to the start of the intervention.)
- Childhood Trauma Questionnaire (CTQ) (Bernstein et al., 1994)(The CTQ will be completed a single time before the intervention begins.)
- Medical Outcomes Study Short-Form (MOS-SF 36) (McHorney et al., 1993)(The MOS-SF 36 will be completed on four occasions over the course of the study : Day 1 Week 1, Day 1 Week 2, Day 1 Week 3, follow up 3 months)
- Toronto Alexithymia Scale (TAS-20) (Bagby et al., 1994)(The TAS-20 will be completed on four occasions over the course of the study. Day 1 Week 1, Day 1 Week 2, Day 1 Week 3, follow up 3 months)
- Difficulties in Emotion Regulation Scale (DERS ; Gratz & Roemer, 2004)(The DERS-F will be completed on four occasions over the course of the study. Day 1 Week 1, Day 1 Week 2, Day 1 Week 3, follow up 3 months)
- Rosenberg Self-Esteem (Rosenberg, 1965)(The Rosenberg Self-Esteem Scale will be completed on four occasions over the course of the study. Day 1 Week 1, Day 1 Week 2, Day 1 Week 3, follow up 3 months)
