Anxiety, Loneliness, Drug Craving, and Depression Among Substance Abusers in Sichuan Province, China

Association between drug craving and aggression in Chinese male methamphetamine-dependent patients with and without depressive symptoms

Depressive symptoms and aggression are common in patients with substance use disorder. Drug craving is one of the main drivers of drug-seeking behavior. This study aimed to explore the relationship between drug craving and aggression in methamphetamine use disorder (MAUD) patients with and without depressive symptoms. Totally, 613 male patients with MAUD were recruited in this study. Patients with depressive symptoms were identified by the 13-item Beck Depression Inventory (BDI-13). Drug craving and aggression were assessed by the Desires for Drug Questionnaire (DDQ) and the Buss & Perry Aggression Questionnaire (BPAQ), respectively. 374 patients (61.01%) were confirmed to meet the criteria of depressive symptoms. Patients with depressive symptoms had significantly higher DDQ and BPAQ total scores than those without depressive symptoms. DDQ desire and intention were positively correlated with verbal aggression and hostility in patients with depressive symptoms, whereas they were correlated with self-directed aggression in patients without depressive symptoms. In patients with depressive symptoms, DDQ negative reinforcement and a history of suicide attempts were independently associated with BPAQ total score. Our study suggests that male MAUD patients have a high incidence of depressive symptoms and that patients with depressive symptoms may have greater drug cravings and aggression. Depressive symptoms may play a role in the association between drug craving and aggression in patients with MAUD.

Social Health and Its Influence on Metabolic Health Among a Rural Population: A Cross-Sectional Study

The aim of this study was to estimate the prevalence of metabolic syndrome (MetS) in a Spanish rural population and assess differences in prevalence according to loneliness level, social isolation, and social support. This is a cross-sectional study of 310 patients. MetS was defined by National Cholesterol Education Program-Third Adult Treatment Panel. The UCLA (University of California, Los Angeles) Loneliness Scale, Multidimensional Scale of Social Support, and Lubben Social Network Scale were used to assess loneliness, perceived social support, and social isolation. Almost half of the participants fulfilled MetS diagnosis criteria. Subjects with MetS showed significantly higher levels of loneliness, less social support, and greater social isolation. Systolic blood pressure was significantly higher in socially isolated rural adults. Environmental factors may play a key role in the prevalence of MetS, so specific screening and prevention programs could help health professionals prevent the increasing rates of MetS in rural populations under these socially specific conditions of vulnerability.

Depression in Chinese men with methamphetamine dependence: Prevalence, correlates and relationship with alexithymia

BACKGROUND

The comorbidity between substance use disorder and major depressive disorder is a typical dual diagnosis in the field of substance addiction. However, the prevalence and correlates of depression in methamphetamine addicts and whether it is associated with drug craving and alexithymia have been rarely reported in the Chinese population.

METHODS

We recruited 585 methamphetamine-dependent males from a drug rehabilitation center in China and 203 healthy controls. Demographic and drug use data were collected. Depression was assessed using the Mini International Neuropsychiatric Interview (M.I.N·I.). Methamphetamine cravings and alexithymia were assessed using the Desire for Drugs Questionnaire (DDQ) and the Toronto Alexithymia Scale (TAS).

RESULTS

The prevalence rate of depression in methamphetamine-dependent men was 16.58 % (97/585). The scores of DDQ desire and intention, DDQ negative reinforcement, total DDQ, difficulty identifying feelings (DIF), difficulty describing feelings (DDF), and total TAS score of depressed patients were higher than those of non-depressed patients. However, only DDQ negative reinforcement score, DIF, DDF, and total TAS score remained significant after Bonferroni correction. Additionally, logistic regression analysis found that age, DIF score, and DDQ negative reinforcement score were significant factors contributing to depression in methamphetamine-dependent men.

CONCLUSION

Our findings suggest that the prevalence of depression is significantly higher in methamphetamine-dependent men than in the healthy Chinese population. Furthermore, age, components of alexithymia and drug craving are risk factors for depression in methamphetamine addicts.

Assessing Loneliness among Adults Receiving Outpatient Treatment with Medication for Opioid Use Disorder (MOUD)

Loneliness is a significant risk factor for substance use, however, impacts of treatments on loneliness are relatively unexplored. Living in a rural location is a greater risk factor for loneliness. This study examined data from a quasi-experimental study in rural Appalachia, comparing the effectiveness of Mindfulness-Based Relapse Prevention (MBRP) versus Treatment as Usual (TAU) among adults receiving MOUD in outpatient therapy. Our objective was to determine whether observed reductions in self-reported craving, anxiety, depression, and increased perceived mindfulness would also improve loneliness reports. Eighty participants (n = 35 MBRP; n = 45 TAU) were included in the analysis from a group-based Comprehensive Opioid Addiction Treatment program. Outcomes tracked included craving, anxiety, depression, mindfulness, and loneliness as measured by the Revised UCLA Loneliness Scale (R-UCLA). A linear mixed model ANOVA determined the significance of the treatments on changes in loneliness scores at baseline, 12 weeks, 24 weeks, and 36 weeks post-recruitment. Both groups reported significantly reduced loneliness over the course of the study (F = 16.07, p < 0.01), however there were no significant differences between groups. Loneliness was also significantly positively (p < 0.01) correlated with anxiety (0.66), depression (0.59), and craving (0.38), and significantly (p < 0.01) inversely correlated (-0.52) with mindfulness. Results suggest that participation in MOUD group-based outpatient therapy has the potential to diminish loneliness and associated poor psychological outcomes. Thus, it is possible that a more targeted intervention for loneliness would further diminish loneliness, which is important as loneliness is linked to risk for relapse.
