Social Support and Drug Abstention Motivation among Chinese Male Drug Addicts: A Moderated Mediation Model of Self-Control and Sensation-Seeking

Longitudinal associations between loneliness and online game addiction among undergraduates: A moderated mediation model

Online gaming addiction (OGA) has become a noteworthy public concern, especially among university students, thereby requiring in-depth scrutiny. Although previous cross-sectional studies have established a positive link between loneliness and OGA, there is a lack of longitudinal evidence within this field. Moreover, the underlying mechanisms that elucidate the connection between loneliness and OGA are still poorly understood, underscoring a crucial research gap that requires further investigation. Our study utilized a longitudinal approach and developed a moderated mediation model. From September 2021 to September 2022, during the COVID-19 pandemic, data were collected from a sample of Chinese undergraduate students, with 367 participants at T1, 352 at T2, and 340 at T3. Participants completed online self-report surveys, providing valuable data on their levels of loneliness at T1, fear of missing out (FoMO) at T2, sensation seeking at T2, and OGA at T3. Our findings found that loneliness was positively linked to OGA. Further analysis demonstrated that FoMO partially mediated the link between loneliness and OGA. Meanwhile, sensation seeking moderated the pathway from FoMO to later OGA. Specifically, the effect of FoMO on OGA was significant for college students with high sensation seeking. This study offers longitudinal evidence linking loneliness and OGA, which has implications for the development of interventions to reduce OGA.

Operant novelty seeking predicts cue-induced reinstatement following cocaine but not water reinforcement in male rats

RATIONALE

An important facet of cocaine addiction is a high propensity to relapse, with increasing research investigating factors that predispose individuals toward uncontrolled drug use and relapse. A personality trait linked to drug addiction is high sensation seeking, i.e., a preference for novel sensations/experiences. In an animal model of sensation seeking, operant novelty seeking predicts the acquisition of drug self-administration.

OBJECTIVE

The primary goal of this research was to evaluate the hypothesis that sensitivity to the reinforcing effects of novel sensory stimuli predicts more intensive aspects of drug-taking behaviors, such as relapse.

METHODS

Rats were first tested for Operant Novelty Seeking, during which responses resulted in complex visual/auditory stimuli. Next, rats were trained to respond to water/cocaine reinforcers signaled by a cue light. Finally, rats were exposed to extinction in the absence of discrete cues and subsequently tested in a single session of cue-induced reinstatement, during which active responses resulted in cues previously paired with water/cocaine delivery.

RESULTS

The present study showed operant responses to produce novel sensory stimuli positively correlate with responding for cocaine during self-administration and during discrete cue-induced reinstatement, but no association with performance during extinction. A different pattern of associations was observed for a natural reward, in this case, water reinforcement. Here, the degree of novelty seeking also correlated with responding to water reinforcement and extinction responding; however, operant novelty seeking did not correlate with responding to water cues during testing of cue-induced reinstatement. Taken together, the incongruence of relationships indicates an underlying difference between natural and drug reinforcers.

CONCLUSION

In summary, we found a reinforcer-dependent relationship between operant novelty seeking (i.e., sensation seeking) and responsivity to extinction and discrete cues signaling availability for cocaine (i.e., craving), demonstrating the validity of the operant novelty seeking model to investigate drug seeking and relapse.

"…he's going to be facing the same things that he faced prior to being locked up": perceptions of service needs for substance use disorders

BACKGROUND

High rates of substance use disorders (SUDs) exist among justice-involved populations (i.e., persons incarcerated or recently released). SUD treatment is crucial for justice-involved populations as unmet treatment need increases reincarceration risk and impacts other behavioral health sequalae. A limited understanding of health needs (i.e. health literacy) can be one reason for unmet treatment needs. Social support is critical to seeking SUD treatment and post-incarceration outcomes. However, little is known about how social support partners understand and influence SUD service utilization among formerly incarcerated persons.

METHODS

This mixed method, exploratory study utilized data from a larger study comprised of formerly incarcerated men (n = 57) and their selected social support partners (n = 57) to identify how social support partners understand the service needs of their loved ones recently released from prison who returned to the community with a diagnosis of a SUD. Qualitative data included 87 semi-structured interviews with the social support partners covering post-release experiences with their formerly incarcerated loved one. Univariates were conducted on the quantitative service utilization data and demographics to complement the qualitative data.

RESULTS

Majority of the formerly incarcerated men identified as African American (91%) averaging 29 years of age (SD = 9.58). Most social support partners were a parent (49%). Qualitative analyses revealed that most social support partners avoided using or did not know the language to use regarding the formerly incarcerated person's SUD. Treatment needs were often attributed to focus on peer influences and spending more time at their residence/housing. Analyses did reveal that when treatment needs were recommended in the interviews, social support partners reported employment and education services to be most needed for the formerly incarcerated person. These findings align with the univariate analysis with their loved ones reporting employment (52%) and education (26%) as their most reported service utilized post-release, compared to only 4% using substance abuse treatment.

CONCLUSION

Results provide preliminary evidence suggesting social support partners do influence the types of services accessed by formerly incarcerated persons with SUD. The findings of this study emphasize the need for psychoeducation during and after incarceration for individuals with SUDs and their social support partners.
