Rumination and worry as putative mediators explaining the association between emotional disorders and alcohol use disorder in a longitudinal study

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.

The validity of transdiagnostic factors in predicting homotypic and heterotypic continuity of psychopathology symptoms over time

Studies of the continuity of psychopathology symptoms mainly involved the traditional conceptualization that mental disorders are discrete entities. However, high comorbidity rates suggest a few transdiagnostic factors that underlie individual disorders. Therefore, the present study examined the validity of transdiagnostic factors in predicting homotypic and heterotypic continuity of comorbidity classes across two waves in a nationally representative sample. We conducted a latent transition analysis to investigate how transdiagnostic factors differentially affect the transition probabilities of comorbidity classes across time. Results found a notable predictive validity of transdiagnostic factors: (a) internalizing strongly predicted the stability of the internalizing class and transition from the externalizing class to internalizing class, and (b) externalizing predicted the transition from the internalizing class to externalizing class. The study also found a more dynamic prediction pattern leading to equifinality and multifinality of psychopathology symptoms. The findings suggest that transdiagnostic factors can provide information on how individuals' symptom manifestations change over time, highlighting the potential benefits of incorporating transdiagnostic factors into assessment, treatment, and prevention.

Individually delivered mindfulness-based cognitive therapy in concomitant problematic substance use and emotional symptoms: A process-based case study

The process-based approach assumes that transdiagnostic psychological processes are involved in the onset and maintenance of mental disorders. Case conceptualization is used to identify such psychological processes and to individualize the intervention accordingly. This approach is fundamentally different from syndrome-based approaches in which standardized treatments are administered for psychiatric diagnoses or symptoms. In the current case, we proposed a process-based conceptualization and treatment for a woman with concomitant problematic substance use and emotional symptoms. Our idiosyncratic process-based conceptualization showed that for this person, substance abuse consisted in a maladaptive coping strategy to deal with repetitive negative thinking and poor emotion regulation skills, for which we decided to use a mindfulness-based intervention. Treatment comprised 8 weeks of individually delivered mindfulness-based cognitive therapy sessions. A comprehensive assessment of psychiatric symptoms and psychological processes was conducted at baseline, post-intervention and 3-month follow-up. The post-treatment assessment revealed that psychological processes targeted by the intervention were improved, together with the mindfulness trait. At the symptom-based level, we observed a significant reduction in substance abuse and emotional symptoms. Treatment gains were maintained at follow-up. From a process-based perspective, this result implies that the intervention successfully targeted the psychological processes underlying the presenting symptoms. Adopting a process-based approach rather than symptom- or syndrome-based approaches is a valuable alternative in the conceptualization and treatment of complex cases presenting with multiple comorbidities.

Do people who highly value happiness tend to ruminate?

Previous studies have suggested that an extremely strong desire for happiness might ironically reduce a person's well-being, particularly among Western people. According to the goal progress theory and the theory of valuing happiness, rumination might explain the relationship between valuing happiness and well-being. Based on these theoretical rationales, this study examined the following hypotheses: (1) valuing happiness is significantly associated with rumination, (2) people who experience low life stress have a stronger association between valuing happiness and rumination, and (3) people with more interdependent self-construal have a weaker association between valuing happiness and rumination. University students in Japan participated in a cross-sectional study (N = 350; Study 1) and a 4-weeks longitudinal study (N = 329; Study 2). They responded to a packet of questionnaires assessing valuing happiness, trait rumination, depressive symptoms, negative events, and interdependent self-construal. Consistent with our hypothesis, valuing happiness was concurrently and longitudinally associated with increased rumination after controlling for depressive symptoms. However, negative events did not moderate the association between valuing happiness and rumination. Furthermore, Study 1, but not Study 2, indicated that the association between valuing happiness and rumination was stronger among students with highly interdependent self-construal than those with less interdependent self-construal. The preset findings indicated that valuing happiness might be a factor that perpetuates rumination. More sophisticated evidence on the influence of valuing happiness on rumination can lead to effective psychotherapies for decreasing rumination and depression.

Psychometric properties of the Smartphone Addiction Inventory - Short Form (SPAI-SF) in Brazilian adolescents

The Smartphone Addiction Inventory - Short Form (SPAI-SF) is shorter version (10 items) of the original version of SPAI (26 items). In this study, we aimed to: (i) adapt and test the internal structure of the SPAI-SF, using confirmatory factor analysis (CFA), multigroup confirmatory factor analysis (MGCFA), and network analysis; (ii) analyze the internal consistency, temporal stability, criterion, predictive and construct validities of the SPAI-SF. A total of 392 adolescents (M = 12.76; SD = 1.00) completed the following measures: demographic questionnaire, SPAI-SF, Smartphone Addiction Scale - Short Version (SAS-SV), and the Internet Addiction Test (IAT). The CFA showed good fit indices with the original four factors, and MGCFA indicated measurement invariance for gender. Network analysis provided an understanding of the core symptoms of problematic smartphone use (PSU) for both boys and girls. The intraclass correlation coefficient (ICC) was 0.865 (95% CI: 0.841 - 0.887) and indicated a robust temporal stability. The instrument demonstrated acceptable overall reliability measured by Cronbach's alpha and McDonald's Omega criteria (α = 0.722; ω = 0.725) and did not show floor and ceiling effects. The scale's significant correlations demonstrated convergent and criterion validities of the SPAI-SF with SAS-SV, IAT, and Smartphone usage data. The SPAI-SF is a reliable instrument to detect PSU in adolescents.

Social Undermining and Interpersonal Rumination among Employees: The Mediating Role of Being the Subject of Envy and the Moderating Role of Social Support

Rumination is a common problem and is associated with reduced psychological well-being. However, little is known about how rumination in the workplace is affected by interpersonal relationships. We propose that negative workplace behavior could serve as a potential influencing factor for rumination. Therefore, the current study constructed a multilevel moderated mediation model to investigate the relationship between workplace unit social undermining and interpersonal rumination. We also examined whether unit social support moderated that relationship and whether being the subject of envy mediated that relationship. Survey data were collected from 630 employees in China. The results indicate that: (1) a high level of unit social undermining by either a supervisor or co-workers has a significant positive influence on interpersonal rumination; (2) being the subject of envy exerts a mediating effect between unit supervisor social undermining and interpersonal rumination, as well as between unit co-worker social undermining and interpersonal rumination; and (3) unit social support moderates the associations between unit supervisor/co-worker social undermining and interpersonal rumination. These findings extend the research on rumination to the field of management and interpersonal relationships and emphasize the potential mechanisms of rumination, providing significant guidance for reducing staff rumination and improving psychological well-being.

Alcohol Use of German Adults during Different Pandemic Phases: Repeated Cross-Sectional Analyses in the COVID-19 Snapshot Monitoring Study (COSMO)

There is little evidence on how different COVID-19 pandemic phases influence the alcohol use behaviour of adults. The objective of this study is to investigate alcohol use frequency over different COVID-19 pandemic phases and to identify vulnerable subgroups for risky use behaviour in the German adult population. Survey waves of 14/15 April 2020 (n = 1032), 23/24 June 2020 (n = 993), and 26/27 January 2021 (n = 1001) from the COVID-19 Snapshot Monitoring (COSMO) were analysed. The mean age was 46 ± 15.3 years in April, 46 ± 15.5 years in June, and 45 ± 15.5 years in January. The gender ratio was mostly equal in each survey wave. Descriptive analyses and univariate and multivariate logistic regression analyses for individuals with increased alcohol use frequency (AUF) were performed. 13.2% in April (lockdown), 11.3% in June (easement), and 8.6% in January (lockdown) of participants showed an increased AUF. Individuals with perceived burden, high frustration levels due to protective measures, and young to middle-aged adults were more likely to increase their AUF during different pandemic phases. In conclusion, unfavourable alcohol behaviour might occur as a potentially maladaptive coping strategy in pandemics. Because of potential negative long-term consequences of problematic alcohol use behaviour on health, public health strategies should consider mental health consequences and target addictive behaviour, while also guiding risk groups towards healthy coping strategies such as physical activities during pandemics/crises.

Repetitive negative thinking, metacognitive beliefs, and their interaction as possible predictors for problematic cannabis use

The metacognitive formulation of addictive behaviours considers repetitive negative thinking (RNT) and metacognitive beliefs as two important processes involved in the development and maintenance of addictive behaviours. To date, very limited research has investigated the implication of these processes in problematic cannabis use. The present study was aimed at exploring the association between RNT, metacognitive beliefs, and cannabis use in a sample of 157 problematic cannabis users. Participants were administered measures of cannabis use severity, RNT, metacognitive beliefs, anxiety, and depression. Multiple regression analysis showed that metacognitive beliefs (cognitive confidence, beliefs about the need to control thought, and cognitive self-consciousness) were independent predictors of problematic cannabis use and related problem severity when controlling for RNT and negative affect (anxiety and depression). Furthermore, RNT predicted problematic cannabis use severity only for users with low levels of negative beliefs about thoughts concerning uncontrollability and danger. These data suggest that metacognitive beliefs and RNT may be two relevant cognitive processes for understanding problematic cannabis use. More generally, it enables the consideration of cannabis use from the perspective of self-regulation theories, and more specifically cognitive regulation, thus offering several theoretical and clinical implications.
