Stability of and change in substance use risk personality: Gender differences and smoking cigarettes among early adolescents

Unveiling the Heterogeneity of Sensation Seeking and Collectivism Development in Chinese Adolescents

OBJECTIVE

Understanding the impact of sociocultural tendencies on the personality development of adolescents represents a critical theoretical and practical issue in the field of adolescent development. In the context of China's collectivist culture, the developmental trajectories of and the interaction between sensation seeking and collectivism among adolescents remain largely unknown.

METHOD

This study examined the heterogeneity of the joint growth patterns of sensation seeking and collectivism and their interactions across distinct latent trajectory classes. We collected 3-year longitudinal data from 20,225 Chinese adolescents (60.45% male).

RESULTS

We identified four unique joint developmental trajectories. Contrary to the traditional view that collectivism inherently suppresses sensation seeking, most adolescents (89.52%) exhibited synchronous growth of both dimensions. The development of adolescent sensation-seeking behavior was significantly influenced by their alignment with societal contribution-driven happiness and an unquestioning prioritization of collective interests.

CONCLUSIONS

Our findings underscore the nuanced interplay and commonalities between sensation seeking and collectivism development among Chinese adolescents.

Personality changes related to presence and treatment of substance use (disorders): a systematic review

Heavy substance use (SU) and substance use disorders (SUD) have complex etiologies and often severe consequences. Certain personality traits have been associated with an increased risk for SU(D), but far less is known about personality changes related to SU(D). This review aims to synthesize the existing literature on this research question. A systematic literature search was conducted from November 2022 to February 2023 in PubMed, EbscoHost, and Web of Science. Peer-reviewed original papers on SU(D)-related personality changes were included. Of 55 included studies, 38 were observational population-based studies and 17 were intervention studies. Overall, personality and SU measures, samples, study designs, and statistical approaches were highly heterogenous. In observational studies, higher SU was most consistently related to increases in impulsivity-related traits and (less so) neuroticism, while interventions in the context of SU(D) were mostly associated with increases in conscientiousness and self-efficacy and lasting decreases in neuroticism. Findings for traits related to extraversion, openness, conscientiousness, and agreeableness were mixed and depended on SU measure and age. Studies on bidirectional associations suggest that personality and SU(D) both influence each other over time. Due to their strong association with SU(D), impulsivity-related traits may be important target points for interventions. Future work may investigate the mechanisms underlying personality changes related to SU(D), distinguishing substance-specific effects from general SU(D)-related processes like withdrawal, craving, and loss of control. Furthermore, more research is needed to examine whether SU(D)-related personality changes vary by developmental stage and clinical features (e.g. initial use, onset, remission, and relapse).

Sensation Seeking and Substance use in Chinese Adolescents: Longitudinal Trajectories and Prospective Within-person Associations

Sensation seeking has been extensively demonstrated as a risk factor for substance use. Potential bidirectional associations between sensation seeking and substance use at the within-person level are incompletely understood. The present study examined longitudinal trajectories of sensation seeking and substance use and bidirectional longitudinal associations between sensation seeking and substance use in Chinese adolescents during a 3-year period over three time points. A total of 10,138 adolescents (59.8%) male; M_age = 16.77, SD = 0.83 at time (1) were surveyed. Sensation seeking and substance use frequency increased concomitantly over time. At the within-person level, sensation seeking and substance use were reciprocally predictable, and there were no evidence of sex difference in longitudinal associations. This study provides unique data concerning the relationship between sensation seeking and substance use in a sample of Chinese adolescents, and highlights the importance of identifying sensation seeking behaviors to prevent substance use.

Substance use-related factors and psychosocial characteristics among Turkish adults with early- and late-onset substance use disorder

The onset of substance use is a strong predictor of substance use disorders and related problems. This study examined the differences between early- and late-onset substance use in personality and substance use characteristics, traumatic experiences, and social support with a sample of 100 Turkish adults with substance use disorders. Early onset (<18 years) was associated with more traumatic experiences, increased risk of developing posttraumatic stress disorder (PTSD), and higher levels of depressive symptoms compared to late onset (≥18 years). Also, depressive symptoms, living, and working status were predictors of substance use onset. The study addresses the groups at risk of initiating substance use.

Personality as a Possible Intervention Target to Prevent Traumatic Events in Adolescence

Traumatic events (severe injury, violence, threatened death) are commonly experienced by children. Such events are associated with a dose-response increasing risk of subsequent substance use, mental illness, chronic disease, and premature mortality. Preventing the accumulation of traumatic events is thus an urgent public health priority. Substance use risk personality profiles (impulsivity, sensation seeking, hopelessness, and anxiety sensitivity) may be an important target for preventing trauma exposure, given associations between these personality traits and risky behaviour, substance misuse, and injuries across adolescence. The current study aimed to investigate associations between personality at age 13 and the number of traumatic events experienced by age 18. It also examined associations between traumas before age 13 and personality at age 13. Participants were the control group of a cluster-randomised controlled trial examining prevention of adolescent alcohol misuse. Baseline data were collected at ages 12–13 (2012). Participants were followed-up at ages 18–19 (2017–2018). Personality profiles of hopelessness, anxiety sensitivity, impulsivity, and sensation seeking were measured at baseline using the Substance Use Risk Profile Scale. Traumatic events and age of exposure were measured at age 18–19 using the Life Events Checklist for DSM-5. Mixed-effect regression was conducted on 287 participants in Stata 17, controlling for sex. High scores on hopelessness, impulsivity, and sensation seeking at age 13 were associated with a greater number of traumatic events by age 18. Impulsivity and sensation seeking predicted the number of new traumatic events from age 13 to 18. Prior trauma exposure was associated with high hopelessness at age 13. Adolescents exhibiting high impulsivity or sensation seeking may be at greater risk of experiencing traumatic events. Additionally, early trauma exposure may contribute to the development of a hopelessness personality trait.
