The findings and conclusions of this analysis must be considered in light of some study limitations. Of note, this study was conducted in a country with a high average income. In addition, due to differences in legislation and practices in different countries and intangible variations in patient expectations and experiences, extrapolations of our findings to other settings are likely to involve complex interpretations. The first limitation was that our data on background characteristics and perceived coercion were self-reported. However, self-reporting should not have a major impact on standard background variables, and it should not affect the ratings of perceived coercion, because they are intended to measure self-perception. Second, the individuals studied in this analysis were selected to represent the general SUD treatment population; however, this sample may also be representative of all Norwegian patients. This patient selection should not differ from patients selected in other countries that apply civil commitment when entering treatment under some form of legal pressure; however, our sample may not necessarily be representative of patients in countries that practice only criminal justice acts. Finally, the relatively small sample size may have limited our power to detect important associations of clinical significance.
