Predictors of subgroups based on maximum drinks per occasion over six years for 833 adolescents and young adults in COGA.

ObjectiveA person's pattern of heavier drinking often changes over time, especially during the early drinking years, and reflects complex relationships among a wide range of characteristics. Optimal understanding of the predictors of drinking during times of change might come from studies of trajectories of alcohol intake rather than cross-sectional evaluations.MethodThe patterns of maximum drinks per occasion were evaluated every 2 years between the average ages of 18 and 24 years for 833 subjects from the Collaborative Study on the Genetics of Alcoholism. Latent class growth analysis identified latent classes for the trajectories of maximum drinks, and then logistic regression analyses highlighted variables that best predicted class membership.ResultsFour latent classes were found, including Class 1 (69%), with about 5 maximum drinks per occasion across time; Class 2 (15%), with about 9 drinks at baseline that increased to 18 across time; Class 3 (10%), who began with a maximum of 18 drinks per occasion but decreased to 9 over time; and Class 4 (6%), with a maximum of about 22 drinks across time. The most consistent predictors of higher drinking classes were female sex, a low baseline level of response to alcohol, externalizing characteristics, prior alcohol and tobacco use, and heavier drinking peers.ConclusionsFour trajectory classes were observed and were best predicted by a combination of items that reflected demography, substance use, level of response and externalizing phenotypes, and baseline environment and attitudes

Do Workplace Characteristics Moderate the Effects of Attitudes on Father Warmth and Engagement?

©American Psychological Association, 2020. This paper is not the copy of record and may not exactly replicate the authoritative document published in the APA journal. The final article is available, upon publication, at: https://doi.org/10.1037/fam0000672Though many fathers want to be warmer, more nurturing, and more actively involved than prior generations (i.e., the new fatherhood ideal), they also embrace a father’s traditional role as financial earner. Thus, we hypothesized that fathers’ attitudes about their roles would likely interact with workplace characteristics to produce variations in father warmth and engagement. Using a national sample of 1,020 employed U.S. fathers with children ages 2–8 years old, results suggest that adherence to the new fatherhood ideal was associated with more frequent father engagement and warmth, while endorsing traditional gender norms was associated with less father warmth. Also consistent with prior research showing that family friendly work cultures may enable fathers to be more engaged parents, we find that a family supportive workplace and greater flexibility in when and where fathers work, were associated with more frequent father engagement and warmth. Moreover, interaction results suggest that the associations between job flexibility and engagement are stronger for fathers who do not fully endorse the new fatherhood ideal; associations between workplace support and warmth are also stronger for fathers who do not fully endorse the new fatherhood ideal. Thus, flexibility and a family supportive workplace may particularly enable father involvement for fathers whose attitudes might otherwise be a barrier to their involvement

Familial association of abstinent remission from alcohol use disorder in first-degree relatives of alcohol-dependent treatment-seeking probands

Background and Aims Studies that have included family history of alcohol use disorder (AUD) as a predictor of remission from AUD have yielded few significant results. The goals of this study were to estimate the association of persistent AUD, non-abstinent remission and abstinent remission (‘AUD/remission status’) in a proband with AUD/remission status in a relative and to test whether this association differed in related and unrelated proband-relative pairs. Design High-risk family study of alcohol dependence. Probands were recruited from treatment settings and relatives were invited to participate. Baseline assessments occurred between 1991 and 1998 with follow-up between 1996 and 2005. Half of probands were matched with a biological 1st-degree relative with life-time AUD (related group) and half of probands were paired with an unrelated individual with life-time AUD (unrelated group). Setting Brooklyn, New York; Indianapolis, Indiana; Iowa City, Iowa; San Diego, California; Farmington, Connecticut; and St Louis, Missouri, USA. Participants A total of 606 probands (25.7% female, mean age 37.7) with baseline and follow-up data and 606 of their 1st-degree relatives who had life-ime AUDs (45.8% female, mean age 36.2 years). Measurements Persistent AUD, non-abstinent remission and abstinent remission were based on self-report interview data on most recent AUD symptoms and alcohol consumption. Dependent variable was relatives’ AUD/remission status. Independent variable was probands’ AUD/remission status. Findings A total of 34.6% of probands and 20.6% of relatives were abstinent and 11.1% of probands and 22.8% of relatives were in non-abstinent remission. AUD/remission status was correlated significantly in related (r = 0.23, P = 0.0037) but not in unrelated pairs. A significant interaction of probands’ abstinent remission with a variable representing related (versus unrelated, P = 0.003) pairs suggested a familial association for abstinent remission. In related pairs, individuals with an abstinent proband were more likely to be abstinent themselves than were individuals whose proband had persistent AUD [relative risk ratio = 3.27, 95% confidence interval (CI) = 1.56–6.85, P = 0.002]; this association was not significant in unrelated pairs. Conclusions The likelihood of abstinent remission among people with alcohol use disorder appears to be more than three times greater for individuals who are related to an abstinent proband versus those related to a proband with persistent alcohol use disorder

Aggressive priming online: Facebook adverts can prime aggressive cognitions

Through the process of priming, incidental stimuli in our environments can influence our thoughts, feelings and behavior. This may be true of incidental stimuli in online environments, such as adverts on websites. Two experiments (N=325, N=331) showed that the mere presence of advertisements with violent content on a simulated Facebook page induced higher levels of aggression-related cognition in comparison to non-violent adverts (d=0.56 , d=0.71). In a subsequent word recognition task, participants primed with the violent stimuli 'remembered' more actually-unseen violence-related words than did the control participants. That is, they reported recognizing violent words they had not actually seen. However, priming with violent adverts had no effect on mood or person perception. A third correlational study (N=131) examined whether variance in the extent of priming could be attributed to individual differences in aggressiveness. Participants' aggressiveness was unrelated to their scores on the aggressive cognition measure. These studies established that website adverts with violent content could prime aggressive cognitions. Individuals differed in the extent to which they experienced the priming effect, and this was not attributable to their levels of trait aggressiveness. No effects of priming were found on either mood state or person perception
