Abstract

The main aim of this work was to determine the impact of COMT and DRD2 gene polymorphisms together with temperament and character traits on alcohol craving severity alcohol-dependent persons. The sample comprised of 89 men and 16 women (aged 38±7). For the sake of psychological assessment various analytic methods have been applied like the Short Alcohol Dependence Data Questionnaire (SADD), Penn Alcohol Craving Scale (PACS) or Temperament and Character Inventory (TCI) test. The SNP polymorphism of the analyzed genes was determined by Real Time PCR test. The results showed, that the COMT polymorphismmay have an indirected relationship with the intensity and changes in alcohol craving during abstinence. The DRD2 receptor gene polymorphisms are related with the intensity of alcohol craving. It seems that the character traits like “self-targeting”, including “self-acceptance”, are more closely related to the severity of alcohol craving and polymorphic changes in the DRD2 receptor than temperamental traits. Although this is a pilot study the obtained results appeared to be promising and clearly indicate the link betweengene polymorphisms alcohol craving and its severity.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Self-directedness and self-acceptance are more strongly linked to DRD2 polymorphisms than temperamental factors.

    “Notably, traits such as self-directedness and self-acceptance appear more strongly linked to DRD2 polymorphisms than temperamental factors, underscoring the relevance of personality-genotype interactions in addiction vulnerability.”

    From Beyond Stigma–Integrating Neurobiology, Genetics, and Awareness Integration Theory in Addiction Recovery (2026) · cites this paper as [70]

    The Conclusions (page unavailable) associate the DRD2 A/A polymorphism with higher self-acceptance, but also with higher perseverance, a temperamental trait. The Discussion’s Study Limitations section only suggests a possible link to self-directedness. The paper does not establish that these character traits are more strongly linked to DRD2 than temperamental traits are. (LLM, conf=0.87)

  • Polymorphisms in COMT and DRD2 are associated with alcohol craving intensity during abstinence.

    “Polymorphisms in genes such as COMT and DRD2 have been associated with alcohol craving intensity during abstinence.”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
