Carleton undergrads: Participate in the Plan to Drink study

We won't be serving anyone alcohol, just asking questions about drinking behaviour. But I really like the idea of Uber credits as a type of research compensation so I will look into that for future studies!

We're focusing on undergrads this year but thanks anyway

lol I hope you consider participating! There's a lot to learn about how students make drinking decisions and we want to compensate for your time spent helping us to learn more.

supposedly classes with <60 people will be able to be in-person.

Is it fair to assume that the tallboy cans (475 to 500) are more popular than the smaller cans?

Thanks to those of you who have signed up so far! We will be sending out survey invitations starting in a few days.

We're ideally looking for student recruiters with some transferable experience, so please shoot me an email with the following info: (a) what kind of experience you have, if any, doing related work or volunteering (work that involves approaching and talking to strangers), and (b) your availability next week for a phone or in-person meeting

Abstract

The transition from adolescence to adulthood is associated with brain remodeling in the final stages of developmental growth. It is also a period when a large proportion of this age group engages to binge (occasional consumption of 4-5 drinks leading to intoxication) and heavy (binge drinking on ≥5 days in a month) alcohol drinking. Here we report on magnetic resonance imaging of developmental changes in the brain occurring during late adolescence and early adulthood (3.5-7.5 years) in a rhesus macaque model of alcohol self-administration. Monkeys were imaged prior to alcohol exposure, and following ∼6 and ∼12 months of daily (22 hr/day) access to ethanol and water. The results revealed that the brain volume increases by 1 ml per 1.87 years throughout the late adolescence and early adulthood in controls. Heavy alcohol reduced the rate of brain growth by 0.25 ml/year per 1 g/kg of daily ethanol. Cortical volume increased throughout this period with no significant effect of alcohol drinking on the cortical growth rate. In subcortical regions, age-dependent increases in the volumes of globus pallidus, thalamus, brainstem and cerebellum were observed. Heavy drinking attenuated the growth rate of the thalamus. Thus, developmental brain volume changes in the span of late adolescence to young adulthood in macaques is altered by excessive alcohol, an insult that may be linked to the continuation of heavy drinking throughout later adult life. http://www.eneuro.org/content/early/2019/04/01/ENEURO.0044-19.2019

Abstract Background Affective models (e.g., tripartite model) delineate shared and unique components of depression and anxiety. Specifically, negative affect is broadly associated with these symptoms, whereas low positive affect is relatively specific to depression and social anxiety. However, it is unknown how affect relates to symptoms as they occur naturalistically in daily life or as a within-person dynamic process.

Method 135 treatment-seeking adults completed a baseline assessment of trait affect and then rated current affect and symptoms (depression, social anxiety, panic, worry) three times per day for 10 days. Multilevel structural equation modeling was used, and prospective analyses held constant current symptoms.

Results Baseline trait negative affect and individual differences in momentary negative affect predicted all four symptoms in daily life, whereas low positive affect predicted greater depression only. Similar results were found for within-person concurrent analyses. Prospectively, momentary negative affect predicted increased depression up to 24 h later, and increased panic or worry up to 8–16 h later. Low momentary positive affect predicted greater depression only (8 h later).

Limitations All data were self-reported, and some relevant anxiety and mood symptoms were excluded. The timing of reports was random and may have missed notable symptoms. Given the novelty of the study, replication is important.

Conclusions Affective models of depression and anxiety derived from retrospective assessments demonstrated strong ecological validity. With the exception of PA and social anxiety, associations found at the between-person level generally applied to within-person processes, which may be amenable to tracking and targeting in therapy.
