About
Despite scientific, clinical and political incentives, alcohol and/or tobacco screening and brief intervention (SBI) services are poorly implemented in oncology settings. Motivational brief interventions are recognized as particularly effective in changing health behaviors, especially consumption behaviors. The motivational approach is more and more used in primary care setting but still few studies explore its effectiveness with breast cancer patients.
This study aims to compare two intervention arms : educational advices intervention (EAI) versus brief motivational intervention (BMI) for alcohol and/or tobacco consumption in breast cancer women, during their treatment.
In this pilot prospective randomized trial, various psychological and behavioral, variables are measured (alcohol and tobacco consumption, distress, anxiety and depressive disorders, quality of life, motivation for change, empowerment) before the brief intervention, and after 3 and 6 month.
Full description
Context :
It is now well documented that alcohol and tobacco reduce the effectiveness of a treatment, increase the side effects, favor the recurrence and/or secondary cancers and affects the quality of life of patients treated for cancer, including breast cancer. The announcement of the disease could create a window of opportunity for change in lifestyle for patients. The 2014-2019 French Cancer Plan emphasizes the need for the implementation of prevention and risk reduction related to alcohol and tobacco. A screening, brief motivational and referral to treatment program, specifically dedicated to oncology can be public health approach aiming to reduce the harmful consequences of substance misuse and improving the prognosis and quality of life of consumers at risk.
Main objective :
Evaluate effectiveness of a brief motivational intervention for alcohol and/or tobacco in short (3 month) and medium (6 month) terms in breast cancer patients, in a prospective randomized pilot study.
Secondary objectives :
The investigators will seek to highlight the benefit of a motivational brief intervention versus standardized educational advice. The specificity of these interventions is to be integrated in an interview integrating a systematic screening of the emotional distress of the patient, of these concerns as well as of his perceived need for aids.
Method :
This is a randomized clinical trial comparing two interventions. The trial includes 200 primary breast cancer patients with a positive AUDIT-C score and/or are tobacco consumers, randomly placed in two groups :
G1 : Motivational Intervention group (N = 100) : Participants in the intervention group benefit a one-session brief motivational intervention administered by a psychologist. This intervention consist in a single adapted motivational interview lasting 20-30 minutes, based on the principles of the trans-theoretical model and on the manual for motivational therapy. It is carried out by the same psychologist, trained and supervised for this type of intervention.
G2 : Educational advises group (N = 100) : Participants in this group benefit of brief educational advises (10 minutes interview maximum), and received a pamphlet on the health effects of alcohol and tobacco consumption. For obvious ethical reasons, the investigators selected an intervention in the form of advice concerning the effects of the product and the submission of specific documentation (criteria not retained in the context of the brief intervention model). It did not seem possible to evaluate patients without offering them the possibility of a low threshold intervention.
Detailed scripts for each modality of intervention are realized.
Measurement :
Three sets of measurements are taken at baseline, 3-month and 6 month follow-up.
Primary Outcome measures: Clinically significant reduction (beneficial to health) of risk behaviours (alcohol and/or tobacco consumption) :
The intervention will be considered effective if at least one of the two scores (AUDIT or number of cigarettes consumed per day) has decreased by 20% at 3 months (maintained at 6 months) compared to the value collected at baseline, with no increase in the other score.
Secondary outcome measures :
Study procedure :
SCREENING-PRE-INCLUSION: Screening of distress and alcohol/tobacco consumptions is realized when the patients arrive in the oncology department for their chemotherapy treatment, by a research assistant-psychologist. Researchers propose to eligible patients to participate to the study. This first contact permits to check the absence of non-inclusion criteria; to ensure the informed consent of the person (an information and consent note will be given to him) and according to these elements, to define the provisional timetable for participation in the research.
T0 - INCLUSION AND RANDOMIZATION The research assistant retrieves the signed consent, ensuring a time available to return if necessary and carries out the research interview/assessment. The randomization is realized following this interview.
INTERVENTION: Brief intervention (G1 : Brief motivational intervention or G2 : educational advices) are conducted by the research assistant-psychologist, at the Institut Bergonié or by telephone if needed.
T1: MONITORING - FOLLOW-UP(3 months) Assessments are repeated, when the patient comes at the Institut Bergonié, by telephone if necessary.
T2: MONITORING - FOLLOW-UP (6 months) Assessments are repeated, when the patient comes at the Institut Bergonié, by telephone if necessary.
Randomization procedure :
The randomization procedure is done via the TENALEA server, managed by the Epidemiological and Clinical Research Unit (UREC) of the Bergonié Institute.
