Abstract

OBJECTIVE: The authors evaluated whether three neurofunctional domains proposed to be critical in the addiction cycle, namely, incentive salience, negative emotionality, and executive function, could be identified through factor analysis of a deeply phenotyped clinical sample. METHODS: Clinical, behavioral, and self-report measures of addiction, personality, cognition, behavior, and exposure to early-life stress were collected as part of a screening and natural history study of alcohol use disorders in 454 individuals representing the spectrum of alcohol use and use disorders. The multiple indicators, multiple causes (MIMIC) approach was used to identify significant predictors of the latent factors identified by the analysis. RESULTS: The results showed significant support for both three- and four-factor models to explain biobehavioral variation in this sample of participants with alcohol use disorder and control subjects, but the three-factor model had the best fit indices. With some nuances, including cross-correlation (lack of independence) between the three factors, the factors corresponded to incentive salience, negative emotionality, and executive function (executive control). The MIMIC model revealed that both exposure to early-life stress and sociodemographic variables predicted these factors. CONCLUSIONS: These findings suggest that three correlated neurofunctional domains are relevant for alcohol use disorder. More work is required to validate and standardize measures of neurofunctional domains in alcohol use disorder, to extend these findings to other addictive disorders, and to relate variations in them to predisposition, clinical course, treatment response, neuroimaging data, and other psychophysical indicators.

  • In a subsequent study, the three neurofunctional domains proposed to be critical for the addiction cycle (incentive salience, negative emotionality, and executive function) were validated using a factor analysis of a deeply phenotyped clinical sample.

    “In a subsequent study, the three neurofunctional domains that were proposed to be critical for the addiction cycle (incentive salience, negative emotionality, and executive function) were validated using a factor analysis of a deeply phenotyped clinical sample (Kwako et al., 2019; Fig. 3).”

    The Results (Factor Structure) report that factor analysis identified three factors aligning well with the proposed domains in a clinical sample. But the Abstract (Conclusions) says the findings suggest the domains are relevant for AUD and that more work is required to validate and standardize their measures, so saying the domains were validated overstates the finding.

  • In 454 individuals representing the spectrum of alcohol use and AUD, a three-factor model generally demonstrated a good fit with assessment measures, and the factors closely aligned with the Addictions Neuroclinical Assessment domains of incentive salience, negative emotionality, and executive function.

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.
