About this study
This study is a cross-sectional observational study designed to evaluate the diagnostic criteria for behavioral addictions (gambling, online video game disorder, screen addiction, food addiction, and pathological use of sex and/or pornography).
The main objective of this project is to explore the value of the "craving" criterion in the diagnosis of behavioral addictions.

Individuals reporting regular engagement in these different behaviors will be recruited through broad communication campaigns, with the aim of including participants across different levels of severity and thereby better assessing the importance of craving as a diagnostic criterion.
Value of the craving criteria will be evaluated based on:
- its parameters derived from a two-parameter Item Response Theory (IRT) model, namely discrimination (a; the item's ability to distinguish between severity levels) and difficulty (b; the severity level at which the item has a high probability of being endorsed), considered relevant when the values exceed significant thresholds (discrimination > 1 and difficulty within a specific range on the severity continuum);
- its centrality within the network of criteria, as measured by four indices (strength, proximity, interdependence, and expected influence) from network analysis (NA).

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
QuestionnairesOther
- the 9 DSM-5 criteria for gambling and video gaming, plus an item assessing craving (for a total of 10 criteria for these two behaviors),
- the 11 DSM-5 criteria for substance use disorder adapted to addictive behaviors (screen use, eating, and sex).
The total time required to complete the online questionnaires is estimated to be between 5 and 15 minutes, depending on the number of behaviors reported by the participant.
Telephone interviewOther
- the 9 DSM-5 criteria for gambling and video gaming, plus an item assessing craving (for a total of 10 criteria for these two behaviors),
- 11 DSM-5 criteria for substance use disorder adapted to addictive behaviors (screen use, eating, and sex).
The telephone interview will include additional questions from the Addiction Severity Index, covering all of its assessment domains except for the sections on legal issues and family history. This information will be supplemented by an assessment of the Mini International Neuropsychiatric Interview's substance use disorder (SUD) assessment for substances used regularly. All of this data aims to establish a severity profile for each substance or addictive behavior reported as problematic by the participant, taking into account the associated medical, occupational, social, psychological, and consumption dimensions.
The total duration of the telephone questionnaire administration is estimated to be between 30 and 60 minutes, depending on t
| Study group | Role | What they receive |
|---|---|---|
| Telephone Interview | If a participant reports regular use AND has experienced a problem with at least one of the behaviors of interest, he/she will be offered the opportunity to participate in a telephone interview. After obtaining the participant's consent to participate in the research, the participant will be asked to provide their phone number so they can be contacted for a telephone assessment interview. Receives: Other: Telephone interview | |
| Online Questionnaire | If a participant reports regular engagement in at least one of the behaviors of interest without reporting any perceived problems, he/she will be offered the opportunity to participate in an online questionnaire. After obtaining the participant's consent to participate in the research, the participant will be invited to complete an online questionnaire. Receives: Other: Questionnaires |
What is being measured
The primary outcome is the main question the study is designed to answer.
Discrimination parameter (a) of items, estimated with a 2PL IRT model
For each behavioral addiction studied (online gambling, video gaming, screen use, eating, sex/pornography use), the discrimination parameter (a) of all items will be estimated using a two-parameter (2PL) item response theory model.
Measured: Baseline
Difficulty parameter (b) of items, estimated with a 2PL IRT model
For each behavioral addiction studied (online gambling, video gaming, screen use, eating, sex/pornography use), the difficulty parameter (b) of all items will be estimated using a two-parameter (2PL) item response theory model.
Measured: Baseline
Secondary outcomes (3)
Discrimination parameter (a) of the craving criterion across behaviors
The discrimination parameter (a) of the craving criterion will be compared across behaviors (gambling, video games, screen use, eating, sex/pornography) and their subtypes.
Measured: Baseline
Difficulty parameter (b) of the craving criterion across behaviors
The difficulty parameter (b) of the craving criterion will be compared across behaviors (gambling, video games, screen use, eating, sex/pornography) and their subtypes.
Measured: Baseline
Network centrality of the craving criterion across behaviors
Centrality indices (strength, closeness, betweenness, expected influence) of the craving criterion will be compared across behaviors (gambling, video games, screen use, eating, sex/pornography) and their subtypes.
Measured: Baseline
