Abstract
Purpose
Several studies have shown socioeconomic inequalities in psychotropic medication use, but most of these studies are inspired by Andersen’s behavioural model of health care use, which strongly focusses on individuals’ needs. Andersen’s model pays little attention to health care use that is not based on need and insubstantially recognises the context dependentness of individuals. Medicalisation, however, is a context-dependent interactive process that not only interacts with need determinants, but also with non-need determinants that affect health care use. Therefore, this study will examine if psychotropic medication use is stratified, and whether this is not simply the result of differences in need for care, but also influenced by factors not based on need, initiating the stratified medicalisation of mental health symptoms.
Methods
Data from the Belgian Health Interview Survey (BHIS) are used. This study covers information from five successive waves: 2001, 2004, 2013, 2018. The weighted data represent a sample of the adult Belgian population. The research aims are analysed using stepwise Poisson regression models, where the models are also plotted to detect evolutions over time, using marginal means postestimation.
Results
The results reveal that educational inequalities in psychotropic medication use are significant and persistently visible over time. Even after entering need for care, educational inequalities remain significant.
Conclusion
This study shows that psychotropic medication use is stratified and that this is not simply the result of differences in need for care, but also influenced by factors linked to the stratified medicalisation of mental health symptoms.

Appendix 1: Respondent selection criteria
The initial sample size of the BHIS included 73,681 respondents. After excluding year 1997, because there was no data on the dependent variable (N = 10,786), and respondents not aged between 25 and 85 years old (N = 20,285), 42,610 respondents remained. After further excluding missing values on the dependent and independent variables (N = 11,117), the presents study holds data from 31,493 respondents.
