Novel Psychoactive Substance Use and Psychological Trauma: A Multimethodological Analysis.

Background: Authors discuss the connections between novel psychoactive substance (NPS) use and psychological trauma. The transition from classical substances to NPS, a paradigm change, poses a challenge for the treatment systems. Research evidence suggests difficulties in emotion regulation and trauma-related NPS-use. Authors explore some demographic and psychopathological characteristics related to such findings and examine the connections between emotion regulation deficiency and the choice of substance.

Method: This study uses a methodological triangulation of a biologically identified sample to confirm NPS use, a survey method to describe users' socioeconomic characteristics, and Minnesota Multiphasic Personality Inventory (MMPI-2) subscales to study dysfunctions in emotion regulation.

Results: Participants (77 patients) were mainly polydrug users. The transgenerational transfer of substance use was a salient feature, but material deprivation was not characteristic of the entire sample. NPS use was not connected to certain psychopathological characteristics the way classical substance use was. More than half of the respondents had elevated scores on MMPI-2 Demoralization (RCd) and Dysfunctional Negative Emotions (RC7) scales. Nearly half of them also scored high on Neuroticism/Negative Emotionality (NEGE).

Conclusions: Results suggest that NPS use in the context of polydrug use is connected to psychological trauma and emotion regulation deficiency, but the MMPI-2 scales to assess emotional dysfunctions are not connected to a particular type of NPS.
