About this study
Official title: Trajectories and Reactions of Users and Relatives Consulting French Youth Addiction Services (Consultations Jeunes Consommateurs)
In France, the "Consultations Jeunes Consommateurs" (CJC) are the services specialized in the reception of young people for addiction problems. There are more than 500 CJCs throughout France. Depending on the situation, the CJC develops an early intervention strategy aimed either at reducing the risk of developing an addiction or at accelerating entry into appropriate care. The CJCs also meet with family members or professionals who may also independently request help or advice.
Set up by the State since 2004, the action of the CJCs has never been formally evaluated. Only descriptive studies, carried out by the French Observatory of Drugs and Drug Addiction (OFDT), have made it possible to better understand the profile of people who consult CJCs. However, no longitudinal study has yet been carried out to understand the factors associated with the overall evolution of users consulting CJCs, nor with the level of satisfaction of users and those around them. Such objectives are complex, due to the diversity of situations encountered in CJCs and the heterogeneity of the CJCs themselves.
Read the detailed description
This multicenter study will be open to 19 CJC (Consultations jeunes Consommateurs), based on a pre-selection by the partners of structures that are particularly willing to participate in the study (Fédération Addictions, Addictions-France).
However, other CJCs may be included depending on the progress of recruitment.
This recruitment of additional CJCs will be stratified to target a sample of CJCs representative of the CJCs on the metropolitan territory on the following characteristics:
- Region (13 major regions)
- Rural or urban area, as defined by INSEE
- Number of annual consultations
- Conditions
- Addiction
- Medical subject headings
- Behavior, Addictive
What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
| Study group | Role | What they receive |
|---|---|---|
| Users (adolescents or young adults) | 1430 users (adolescents and young adults) with addiction problems and consulting CJC for the first time | |
| Caregivers | 715 caregivers | |
| Consultations Jeunes Consommateurs CJCs | Initial survey (month 0) of participating CJCs: assessment of the "structural" characteristics of the CJCs (type of CJC (hospital, association), urban/rural area, number of users, number of consultations per month, type of workers...) - Telephone interview at the 6th and 12th month: assessment of variables related to the user's pathway (referral to a specialized medical or social service…) |
What is being measured
The primary outcome is the main question the study is designed to answer.
Evolution in Global Appraisal of Individual Needs Short Screener (GAIN-SS) score from first assessment to 12-month assessment
The GAIN-SS scale is a self-administered questionnaire whose responses will be collected by telephone in a standardized manner for all included participants
Measured: Two days ( at month 0 and month 12)
Secondary outcomes (4)
For users: Measurement of satisfaction with CJC use, assessed at 12 months, using the Client Satisfaction Questionnaire - 8 (CSQ-8)
Evaluation of the secondary criterion: Client Satisfaction Questionnaire - 8 (CSQ-8)
Measured: One day (at month 12)
For caregivers : Measurement of satisfaction with CJC use, assessed at 12 months, using the Client Satisfaction Questionnaire - 8 (CSQ-8)
Client Satisfaction Questionnaire - 8 (CSQ-8)
Measured: One day (at month 12)
For caregivers : Evolution in Strengths and Difficulties Questionnaire (SDQ) score from first assessment to 12-month assessment
Strengths and Difficulties Questionnaire (SDQ)
Measured: Two days (at month 0 and month 12)
For all subjects included : Qualitative study : to assess their experience of the CJC's contribution to their needs and expectations
Qualitative study on a sub-sample of caregivers
Measured: One day (month 12)
