The opioid epidemic in the USA, the new psychoactive substances emerging on the market and the recent increase in cocaine treatment demands in Western Europe, all emphasise the importance of monitoring the use and harms of drugs over time. To be informed about new consumption patterns, this study aims to study the trends among people entering treatment for substance use in Belgium.

Belgian data from the Treatment Demand Indicator collected between 2015 and 2019 were used. A reference group of treatment units was selected to allow for comparisons between the different years. Trend analysis was performed by using a joinpoint regression among different regions and groups of clients.

The drugs of choice that were most frequently mentioned among the 23,000 analysed treatment episodes were alcohol and cannabis. Both remained relatively stable over time. Heroin seemed to be decreasing significantly at the national level, but increased in Brussels. Benzodiazepines decreased significantly in Flanders and Brussels, but not in Wallonia. On the other hand, reports of crack cocaine increased significantly in the three regions with a more pronounced trend in Wallonia and Brussels. Substances such as fentanyl, methamphetamine, ketamine or volatile inhalants have been mentioned significantly more by people entering treatment in 2019, although their contribution to the total number is still limited.

To the best of the authors’ knowledge, this study is the first to evaluate trends for all drugs of choice at a national and regional level. These results might not only benefit national policymakers but also other countries with similar alcohol or drug use patterns.

The purpose of this paper is to investigate the association of the satisfaction of the basic psychological needs for competence, autonomy, and relatedness with affective commitment and turnover intentions among retail employees in India while also examining the mediating role of job satisfaction in these associations.

Research hypotheses were tested using a cross-organizational sample of 244 employees. Existing, established scales were used to measure the research constructs.

The results of this study show that the satisfaction of the needs for competence, autonomy, and relatedness was positively related to affective commitment and negatively related to turnover intentions. Moreover, the results indicate that job satisfaction mediated the association of basic psychological need satisfaction with affective commitment and turnover intentions.

This study highlights the significant role of basic psychological need satisfaction in retaining employees in a rapidly growing economy that is experiencing very high employee turnover. The findings of this study may be helpful for organizational leaders in taking appropriate actions to create working conditions that facilitate the satisfaction of employees’ basic psychological needs. Satisfaction of employees’ basic psychological needs at work may help in retaining them in the current economic scenario, which is witnessing very high employee turnover.

This research tested the applicability of basic psychological need satisfaction to Eastern collectivistic cultures, particularly to India. Recent socio-economic changes, unique workforce demographics and a predominantly collectivistic culture make India distinct from western and European countries, where most of the earlier research on understanding the nature, antecedents, and consequences of basic psychological need satisfaction has been conducted. This research provides an important contribution not only to basic psychological need satisfaction theory, but also to international business literature.
