The Engagement of Non-substance-Related Pleasant Activities Is Associated with Decreased Levels of Alcohol Consumption in University Students

Interventions that focus on changing environmental contingencies through exposure to alternative reinforcers, in order to provide a lifestyle that is more rewarding than one that includes high levels of alcohol consumption, have been shown to be highly efficacious. The objective of this study was to examine the relationship between activity engagement in terms of pleasant substance related and non-substance activities (SRA/non-SRA) and levels of alcohol consumption among university students. A study involving 286 students looked specifically at levels of alcohol consumption and non-SRA/SRA. Levels of alcohol consumption were strongly and positively correlated with SRA (r = 0.69), but also with non-SRA (r = 0.28). A finer-grained analysis showed that the relationship between positive SRA and level of alcohol consumption is weakened by the inclusion of non-SRA as a third variable. Non-SRA seem to attenuate the level of alcohol consumption in the context of SRA. Alcohol consumption among university students could plausibly be reduced by focusing on promoting appealing and healthy non-substance-related rewarding activities

Is Older Age Associated with Higher Self- and Other-Rated ASD Characteristics?

Autism spectrum disorder (ASD) characteristics seem to abate over time, but whether this protracts until late adulthood is largely unknown. We cross-sectionally investigated self- and other-reported ASD characteristics of adults with (ASD: Nmax-self = 237, Nmax-other = 130) and without ASD (COM: Nmax-self = 198, Nmax-other = 148) aged 19–79 years. Within the ASD group, self-reported ASD characteristics, and sensory sensitivities were highest in middle adulthood, while age was not associated to empathy. Sex differences were also found. However, age-and sex-related differences were not revealed by others and self- and other-report were poorly concordant. These results show that ASD characteristics in adulthood are differently perceived across age, sex, and informants and suggest that it is important to repeatedly assess self-reported ASD characteristics during adulthood
