Dynamic networks of psychological symptoms, impairment, substance use, and social support: The evolution of psychopathology among emerging adults

Abstract

Background. Subthreshold/attenuated syndromes are established precursors of full-threshold mood and psychotic disorders. Less is known about the individual symptoms that may precede the development of subthreshold syndromes and associated social/functional outcomes among emerging adults. Methods. We modeled two dynamic Bayesian networks (DBN) to investigate associations among self-rated phenomenology and personal/lifestyle factors (role impairment, low social support, and alcohol and substance use) across the 19Up and 25Up waves of the Brisbane Longitudinal Twin Study. We examined whether symptoms and personal/lifestyle factors at 19Up were associated with (a) themselves or different items at 25Up, and (b) onset of a depression-like, hypo-manic-like, or psychotic-like subthreshold syndrome (STS) at 25Up. Results. The first DBN identified 11 items that when endorsed at 19Up were more likely to be reendorsed at 25Up (e.g., hypersomnia, impaired concentration, impaired sleep quality) and seven items that when endorsed at 19Up were associated with different items being endorsed at 25Up (e.g., earlier fatigue and later role impairment; earlier anergia and later somatic pain). In the second DBN, no arcs met our a priori threshold for inclusion. In an exploratory model with no threshold, >20 items at 19Up were associated with progression to an STS at 25Up (with lower statistical confidence); the top five arcs were: feeling threatened by others and a later psychotic-like STS; increased activity and a later hypo-manic-like STS; and anergia, impaired sleep quality, and/or hypersomnia and a later depression-like STS. Conclusions. These probabilistic models identify symptoms and personal/lifestyle factors that might prove useful targets for indicated preventative strategies.

Causal and common risk pathways linking childhood maltreatment to later intimate partner violence victimization

“…Other traits that have been associated with revictimization (e.g., low self-control ( 39 , 103 ), high risk-taking ( 104 , 105 )), may also play a role in the association between maltreatment and IPV, contributing to its genetic component. Additionally, the genetic component of revictimization may encompass genetic influences on psychological processes, including cognitive biases, affecting how individuals perceive, interpret, and recall childhood experiences ( 106 - 108 ). Future research should clarify how heritable traits and psychological processes influence the selection and attraction of intimate partners among maltreatment survivors.…”

Is There a Relationship between Psychotic Disorders and the Radicalization Process? A Systematic Review

“…A complex relationship has been proposed between the radicalization process and the presence of mental disorders in perpetrators [ 15 , 16 , 17 ], which can be useful to study in order to identify possible protective and risk factors [ 5 ]. However, available data are controversial, and no mental disorder can be considered as a specific risk factor for radicalization [ 18 , 19 , 20 ].…”

Impact of the Post Pandemic on College Student’ Lifestyles

“…As a consequence of the presence of Covid-19 there were many losses of loved ones, which influenced many lifestyles in young people and adults bringing with it problems of anxiety and depression in university students (Huamán-Romaní et al, 2021), this problem is usually caused by those students who lead an unhealthy lifestyle because they smoke, do not have physical activities and consume alcohol, but it is less frequent in those students who have a healthy lifestyle (Jang et al, 2022), in Covid-19 times the internet was a practice of a sedentary lifestyle, there was even a seizure to online shopping and thanks to the intervention it was possible to avoid chronic diseases and indebtedness because this psychotic disorder is related to the lifestyle of university students (Crouse et al, 2022).…”
