Rumination and problematic substance use among individuals with a long-term history of illicit drug use

The Association Between Rumination and Craving in Chinese Methamphetamine-Dependent Patients: The Masking Effect of Depression

BACKGROUND

Craving is a core feature of addiction. Rumination and depression play a crucial role in the process of methamphetamine addiction. The aim of this study was to examine the relationship between rumination, depression and craving in methamphetamine patients, which has not been explored yet.

METHODS

A total of 778 patients with methamphetamine user disorder (MUD) at the Xinhua Drug Rehabilitation Center, located in Mianyang City, Sichuan Province, China. We used a set of self-administered questionnaires that included socio-demographic, detailed drug use history, rumination, depression and craving information. The Rumination Response Scale (RRS) was used to measure rumination, the Beck Depression Inventory (BDI) to measure depression and the Visual Analogue Scale (VAS) to measure craving.

RESULTS

There was a significant positive correlation between rumination and craving, or depression, and between depression and craving. Furthermore, depression mediated between rumination and craving, with a mediation effect of 160%.

CONCLUSIONS

Our findings suggest that there is a close interrelationship between rumination, craving and depression in MUD patients, and that depression may play a mediating role between rumination and craving.

Association between rumination and drug craving in Chinese male methamphetamine use disorder patients with childhood trauma

BACKGROUND

In China, males make up the majority of methamphetamine (MA) dependent individuals and the majority of treatment seekers. Childhood trauma (CT) and rumination are associated with an increased risk of MA use. However, the association between CT, rumination, and drug craving remains largely unknown.

OBJECTIVE

The present study aims to explore the association between rumination and drug craving in methamphetamine use disorder (MAUD) patients with CT.

PARTICIPANTS AND SETTING

This study recruited 404 male participants with MAUD from a male drug rehabilitation center in Southwest China.

METHODS

Patients with CT were identified by the short form of Childhood Trauma Questionnaire (CTQ-SF). Rumination and drug craving were assessed by the Ruminative Responses Scale (RRS) and the Obsessive Compulsive Drug Use Scale (OCDUS), respectively.

RESULTS

188 patients (46.5 %) experienced CT. Patients who had experienced CT showed significantly higher RRS symptom rumination score and OCDUS total score than those who had not. In patients with CT, RRS total and all subscale scores were positively associated with OCDUS interference of drug. Furthermore, the RRS brooding (β = 0.34, p < 0.001) and total scores (β = 0.38, p < 0.001) were determined to be separate contributors to the OCDUS total score in patients with CT.

CONCLUSIONS

Our study suggests that CT is common in male MAUD patients, and those who have suffered CT may exhibit higher levels of rumination and drug craving. Moreover, CT may play an influential role in the association between rumination and drug craving in patients with MAUD.

Psychological distress, rumination and problematic smartphone use among Spanish adolescents: An emotional intelligence-based conditional process analysis

BACKGROUND

Problematic smartphone use (PSU) is a public health issue that is currently rising among adolescents. The Compensatory Internet Use Theory (CIUT) poses that difficulties in handling negative life circumstances could result in PSU. Furthermore, the Interaction of Person-Affect-Cognition-Execution (I-PACE) model suggests that the interaction between core characteristics and affective and cognitive responses could lead to PSU. The present study aimed to clarify the links between psychological distress and PSU by exploring rumination as a mediator and emotional intelligence (EI) as a moderator.

METHODS

A sample of 1882 adolescents (54% female, 46% male) completed measures of psychological distress, rumination, EI and PSU. The PROCESS macro was used to conduct a moderated mediation analysis.

RESULTS

The mediation results showed a significant indirect effect from psychological distress to PSU through rumination. Furthermore, EI was a significant moderator of this effect. Thus, in adolescents with higher EI, the effect of psychological distress on PSU through rumination was not significant.

LIMITATIONS

Cross-sectional data do not imply causality and further studies should use longitudinal designs. Self-report questionnaires may be susceptible to social desirability bias and future studies including other sources of information may help to minimize such bias.

CONCLUSIONS

This study contributes to the field of problematic digital technology usage, showing that the link between psychological distress and PSU depends on the EI levels, which might influence PSU indirectly through rumination. Furthermore, empirical evidence for the CIUT and I-PACE models was provided. Lastly, interventions aiming at training EI may aid in the prevention of PSU.

Factors related to substance use among adolescents from six low-and middle-income countries

Substance use is a common public health problem among adolescents in low- and middle-income countries (LMICs), however, factors that are associated with this condition are not clearly understood. The aim of the present study was to examine personal and interpersonal factors that contribute to risk for substance use among adolescents in six ASEAN (Association of Southeast Asian Nations) LMICs (i.e., Indonesia, Laos, Malaysia, Myanmar, Philippines and Thailand). Data of 57,825 adolescents (52.64% girls; median age = 14 years old) who participated in the Global School-based Student Health Survey (GSHS) were analysed. After the weighted prevalence was estimated for each country, multilevel models were employed to examine the influence of the risk factors on the prevalence of substance use across the countries. The results indicated a high prevalence of substance use among adolescents in all these six ASEAN LMICs. Alcohol use, smoking and drug use were more prevalent among adolescents in Thailand, Laos and Philippines. Adolescents who were bullied and who had no close friends had a high prevalence of alcohol and drug use. Problematic drinking and smoking were more prevalent among older adolescents, and smoking and drug use were more prevalent among boys. Furthermore, frequent worry, loneliness and regular physical activity were found to predict adolescents' heavy and binge drinking. This study contributed to knowledge on risk factors for specific substance use among adolescents and drew attention for the urgent need to strengthen the intervention, law policies and professional support for reducing substance use in ASEAN LMICs.

A discriminant analysis model of psychosocial predictors of problematic Internet use and cannabis use disorder in university students

Researchers have found similarities and differences between behavioral and drug addictions. The present study was designed to explore which of a series of psychosocial predictors of addictive behaviors could differentiate problematic Internet use (PIU) and Cannabis Use Disorder (CUD) in a sample of University students. A total of 144 participants (76 males, mean age = 23.03 years ± 2.83) were separated into three groups: those presenting with PIU (18 females, Mean age = 22.27 years), those presenting with CUD (22 female, Mean age = 22.73 years), and a control group (28 female, Mean age = 24.04 years). Participants completed the Internet Abusive Use Questionnaire (IAUQ), the Severity of Dependence Scale (SDS), the Multidimensional Scale of Perceived Social Support (MSPSS), the Barratt Impulsiveness Scale-11 (BIS-11), the Multidimensional Distress Tolerance Scale (MDTS), the Emotion Regulation Questionnaire (ERQ), the Metacognitions Questionnaire-30 (MCQ-30), and the Repetitive Thinking Questionnaire-10 (RTQ-10). The classification analysis results showed that 68.8% of the control group, 70.8% of the PIU group, and 81.3% of the CUD group were correctly classified in their respective groups. In addition, the results of the discriminant function analysis showed that there was a significant difference between members of the PIU and CUD groups in the degree of family support (0.45), significant other (0.33), tolerance of physical discomfort (0.30), reappraisal (0.42), and cognitive confidence (0.35). The findings provide evidence that specific psychosocial predictors can discriminate PIU from CUD.

Anxiety Symptoms and Alcohol-Related Problems among College Students: A Moderated-Mediation Model of Rumination and Emotion Dysregulation

Prior research has individually linked rumination, anxiety, and emotion dysregulation to alcohol misuse, but limited research has examined a comprehensive model linking these variables together. The present study tested a moderated-mediation model to examine whether emotion dysregulation moderated the indirect association of anxiety symptoms on alcohol-related problems via ruminative thinking styles. Method: Participants were 448 college students who consumed alcohol in the previous month. A plurality of participants identified as being White, non-Hispanic (40.6%), female (68.6%), and reported a mean age of 22.75 (Median = 20.00; SD = 6.84) years. Results: Brooding and reflection subtypes of ruminative thinking mediated the association between anxiety symptoms and alcohol-related problems with higher rates of anxiety symptoms associated with higher ruminative thinking, which in turn was associated with more alcohol-related problems. Further, the indirect effect of anxiety symptoms on alcohol-related problems through ruminative thinking was stronger for individuals who reported high levels of emotion dysregulation compared to those with average and low levels of emotion dysregulation. Conclusions: In support of prior work, our results suggest that ruminative thinking, particularly brooding and reflection, are key mechanisms through which anxiety symptoms relate to problematic alcohol use, especially among individuals with high emotion dysregulation. Additional work is needed to test whether decoupling the associations between negative emotional states and ruminative thinking among college students with high emotion dysregulation is a viable intervention target to reduce problematic alcohol use.
