In the HLM analyses, the emotional aspects of impulsivity – N5: Impulsiveness and E5: Excitement-Seeking – were consistently associated with greater weight gain over time across the four measures of adiposity. Such individuals give in to temptation and seek out highly stimulating environments; food and alcohol may be one form of stimulation. And, in fact, sensation seeking has been linked with binge drinking (McAdams & Donnellan, 2009) and overeating (Davis et al., 2007). Such behavior may, over time, contribute to weight gain.
