“…Based on these results, NBH was selected for models of past year alcohol, drug, and marijuana use, and ZINB was used to model negative and positive drinking consequences as well as drug use consequences. For highly-skewed continuous measures of aggression and rule-breaking behavior, semi-continuous (or two-part) regression was used for analysis (Gottard, Stanghellini, & Capobianco, 2013), and coefficients produced by this modeling strategy are interpreted similarly to NBH. Comparisons of model fit using likelihood ratio and Vuong tests for each outcome are provided in Table 2.…”

Young adulthood is a peak period for externalizing behaviors such as substance abuse and antisocial conduct. Evidence from developmental neuroscience suggests that externalizing conduct within this time period may be associated with a “developmental asymmetry” characterized by an early peak in sensation seeking combined with a relatively immature impulse control system. Trait measures of impulsivity—sensation seeking and premeditation—are psychological manifestations of these respective systems, and multiple prior studies suggest that high sensation seeking and low premeditation independently confer risk for distinct forms of externalizing behaviors. The goal of the present study was to test this developmental asymmetry hypothesis, examining whether trait premeditation moderates the effect of sensation seeking on substance use and problems, aggression, and rule-breaking behavior. Using a cross-sectional sample of college-enrolled adults (n = 491), we applied zero-inflated modeling strategies to examine the likelihood and level of risky externalizing behaviors. Results indicated that lower premeditation enhanced the effect of higher sensation seeking on higher levels of positive and negative alcohol consequences, more frequent drug use, and more problematic drug use, but was unrelated to individual differences in antisocial behaviors. Our findings indicate that the developmental asymmetry between sensation seeking and a lack of premeditation is a risk factor for individual differences in problematic substance use among young adults, and may be less applicable for antisocial behaviors among high functioning individuals.

“…Other statistical methods have been applied to semi-continuous data (see Gottard et al 2013, for a review), including linear regression. However, unlike a two-part model, linear regression does not allow for unique or separate predictions of engagement (or not) in a behavior and the level of engagement when it does occur.…”

Using a two-part mixed-effects model for understanding daily, individual-level media behavior

et al. 2019

This study supports a strategic analytics proposal, namely that there is conceptual and practical utility in applying a twopart mixed-effects model for understanding individual differences in daily media use. Individual-level daily diary measures of media use typically contain information about a person's likeliness to use media, extent of usage, and variation in use across days that, taken together, can provide data for evaluating media behavior that is otherwise masked by using aggregate measures. The statistical framework developed and demonstrated here focuses on these three metrics. The approach, applied to daily diary measures of television use in a large, representative U.S. sample, yields results that add value when weighing media strategies centered on the twin tactics of reach and frequency. The implications for the proposed analytic strategy are discussed.
