Characteristics of depression, anxiety, impulsivity, and aggression among various types of drug users and factors for developing severe depression: a cross-sectional study

Validation of the psychoactive substance refusal Self-Efficacy Questionnaire (PSRSEQ) in adolescent case-clients of social workers in Hong Kong

BACKGROUND

Self-efficacy is a key concept in various behavioral theories. Refusal self-efficacy is important in understanding issues related to psychoactive substance use. To facilitate related research, this study translated and validated the Chinese version of the 14-item Psychoactive Substance Refusal Self-efficacy Questionnaire (PSRSEQ) among adolescents. There is a debate about whether such a refusal self-efficacy scale should be unidimensional or multidimensional.

METHODS

A survey was conducted among 601 adolescent case-clients of social workers in Hong Kong from July 2021 to June 2022. Various psychometric properties were examined.

RESULTS

The confirmatory factor analysis (CFA) supported the original 3-factor structure of the PSRSEQ (emotional relief, opportunistic, and social facilitation refusal self-efficacy), which showed satisfactory psychometric properties (internal consistency, convergent validity in terms of significant negative correlations with the intention of psychoactive substance use in the next year and psychoactive substance use behavior in the past six months, and the absence of floor effect) but ceiling effect was obvious. Notably, unacceptable discriminant validity of one subscale and strong correlations among the three subscales were observed. In another set of analyses using two split-half subsamples, the exploratory factor analysis identified a 1-factor 14-item structure, which was confirmed by CFA and showed satisfactory psychometric properties.

CONCLUSIONS

The 1-factor PSRSEQ, instead of the one having a 3-factor structure, was preferred and recommended to assess psychoactive substance refusal self-efficacy among Chinese adolescents. It is warranted to validate the scale in other adolescent and age groups in future studies.

Transcranial magnetic stimulation for methamphetamine use disorder: A scoping review within the neurocircuitry model of addiction

The use of methamphetamine in the United States is increasing, contributing now to the "fourth wave" in the national opioid epidemic crisis. People who suffer from methamphetamine use disorder (MUD) have a higher risk of death. No pharmacological interventions are approved by the FDA and psychosocial interventions are only moderately effective. Transcranial Magnetic Stimulation (TMS) is a relatively novel FDA-cleared intervention for the treatment of Major Depressive Disorder (MDD) and other neuropsychiatric conditions. Several lines of research suggest that TMS could be useful for the treatment of addictive disorders, including MUD. We will review those published clinical trials that show potential effects on craving reduction of TMS when applied over the dorsolateral prefrontal cortex (DLPFC) also highlighting some limitations that affect their generalizability and applicability. We propose the use of the Koob and Volkow's neurocircuitry model of addiction as a frame to explain the brain effects of TMS in patients with MUD. We will finally discuss new venues that could lead to a more individualized and effective treatment of this complex disorder including the use of neuroimaging, the exploration of different areas of the brain such as the frontopolar cortex or the salience network and the use of biomarkers.

Impulsiveness, suicide, and aggression in a sample of patients with disorders of methyl amphetamine use

BACKGROUND

Research has showed a link between patients with methamphetamine dependence and the risk of impulsiveness, aggression, and the risk of suicide. But, this link has not been studied in patients abusing methamphetamine, and it is unknown how impulsiveness, aggression, and the risk of suicide affect them.

MATERIALS AND METHODS

This cross-sectional study included 130 adult patients diagnosed with the disorder of the use of amphetamine, methamphetamine, cannabinoids, alcohol, other substances, and polysubstance admitted in the Addiction Department for Mental Health. Participants were interviewed for detailed psychiatric history using a structured questionnaire comprising of structured clinical interview for diagnosis I, Arabic version of the Barratt Impulsiveness Scale-11 (BIS), Beck Scale for Suicidal Ideation for the evaluation of suicidal ideation and behavior, and the Aggression and Hostility scale for adolescents and youth. SPSS was used for data analysis; Initial analysis included descriptive statistics: frequencies and percentages for categorical variables and mean and standard deviation for continuous variables. Chi-square test/Fisher's exact test assessed for association between categorical variables, whereas one-way analysis of variance (ANOVA)/ Kruskal-Wallis test was used to compare continuous variables.

RESULTS

Patients who used methamphetamine either alone (23%) or with polysubstance (42.6%) were associated with higher suicidal risk than patients who did use other substances than methamphetamine (36.1%). A comparison of the three groups on impulsivity, showed significant difference regarding total scores, motor preservation, and non-planning self-control. No significant differences found between three groups on the aggression scores.

CONCLUSIONS

There was a higher rate of impulsivity and suicidal risk in patients with methamphetamine dependence in comparison to dependence on other substances, while there was no difference with regard to aggression between patients with methamphetamine dependence and those dependent on other substances. This finding raises the issue of methamphetamine use disorder as a new substance of dependence.

Effects of exercise interventions on negative emotions, cognitive performance and drug craving in methamphetamine addiction

Introduction

Methamphetamine is currently one of the most commonly used addictive substances with strong addiction and a high relapse rate. This systematic review aims to examine the effectiveness of physical activity in improving negative emotions, cognitive impairment, and drug craving in people with methamphetamine use disorder (MUD).

Methods

A total of 17 studies out of 133 found from Embase and PubMed were identified, reporting results from 1836 participants from MUD populations. Original research using clearly described physical activity as interventions and reporting quantifiable outcomes of negative mood, cognitive function and drug craving level in people with MUD were eligible for inclusion. We included prospective studies, randomized controlled trials, or intervention studies, focusing on the neurological effects of physical activity on MUD.

Results

Taken together, the available clinical evidence showed that physical activity-based interventions may be effective in managing MUD-related withdrawal symptoms.

Discussion

Physical exercise may improve drug rehabilitation efficiency by improving negative emotions, cognitive behaviors, and drug cravings.

GPR55 activation improves anxiety- and depression-like behaviors of mice during methamphetamine withdrawal

Methamphetamine is a potent and highly addictive neurotoxic psychostimulant that triggers a spectrum of adverse emotional responses during withdrawal. G-protein coupled receptor 55 (GPR55), a novel endocannabinoid receptor, is closely associated with mood regulation. Herein, we developed a murine model of methamphetamine-induced anxiety- and depressive-like behavior during abstinence which showed a decreased GPR55 expression in the hippocampus. Activation of GPR55 mitigated these behavioral symptoms, concomitantly ameliorating impairments in hippocampal neurogenesis and reducing neuroinflammation. These findings underscore the pivotal role of GPR55 in mediating the neuropsychological consequences of methamphetamine withdrawal, potentially via mechanisms involving the modulation of hippocampal neurogenesis and inflammation.

Alterations in the fecal microbiota of methamphetamine users with bad sleep quality during abstinence

BACKGROUND

Methamphetamine (MA) abuse has resulted in a plethora of social issues. Sleep disturbance is a prominent issue about MA addiction, which serve as a risk factor for relapse, and the gut microbiota could play an important role in the pathophysiological mechanisms of sleep disturbances. Therefore, improving sleep quality can be beneficial for treating methamphetamine addiction, and interventions addressing the gut microbiota may represent a promising approach.

METHOD

We recruited 70 MA users to investigate the associations between sleep quality and fecal microbiota by the Pittsburgh Sleep Quality Index (PSQI), which was divided into MA-GS (PSQI score < 7, MA users with good sleep quality, n = 49) and MA-BS group (PSQI score ≥ 7, MA users with bad sleep quality, n = 21). In addition, we compared the gut microbiota between the MA-GS and healthy control (HC, n = 38) groups. 16S rRNA sequencing was applied to identify the gut bacteria.

RESULT

The study revealed that the relative abundances of the Thermoanaerobacterales at the order level differed between the MA-GS and MA-BS groups. Additionally, a positive correlation was found between the relative abundance of the genus Sutterella and daytime dysfunction. Furthermore, comparisons between MA users and HCs revealed differences in beta diversity and relative abundances of various bacterial taxa.

CONCLUSION

In conclusion, the study investigated alterations in the gut microbiota among MA users. Furthermore, we demonstrated that the genus Sutterella changes may be associated with daytime dysfunction, suggesting that the genus Sutterella may be a biomarker for bad sleep quality in MA users.

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.

Serum C-reactive protein level and sleep characteristics in obstructive sleep apnea syndrome comorbid with panic disorder: a preliminary study

OBJECTIVE

Investigate the sleep characteristics of patients with obstructive sleep apnea syndrome (OSAS) comorbidity with panic disorder (PD), exploring its potential association with serum C-reactive protein (CRP) levels.

PATIENTS AND METHODS

Fifty-four patients (25 OSAS patients with PD and 29 without PD) and 25 healthy controls (HCs) were included. The Self-rating anxiety scale (SAS), self-rating depression scale (SDS), and Pittsburgh sleep quality index (PSQI) were used to assess the mood and sleep quality of the subjects. All patients had circulating CRP levels and polysomnography was performed.

RESULTS

OSAS with PD had higher SAS, SDS, PSQI than the OSAS without PD. Compared to OSAS without PD, OSAS with PD had higher percentage of non- rapid eye movement sleep 1 and 2 (N1 and N2%), sleep latency, and a lower percentage of rapid eye movement sleep (REM%). Respiratory-related microarousal index, AHI, and time below 90% oxygen saturation (T90) were low, and the lowest oxygen saturation (LO2) was high. Serum CRP levels in OSAS patients with PD were lower than that in OSAS patients without PD, but higher than that in HCs. In OSAS patients with PD, serum CRP levels were negatively correlated with wake time after sleep onset and SAS scores but positively correlated with sleep efficiency and N2%. Serum CRP levels were positively correlated with T90 and negatively correlated with LO2.

CONCLUSION

OSAS patients with PD had worse sleep quality, less severe OSAS, and low serum CRP levels. Serum CRP levels in OSAS patients with PD were associated with poorer sleep quality and duration of hypoxia rather than AHI.

Bio-Psycho-Social Profile of People with Substance Use Disorders Treated in Locally Assigned Treatment Facilities in Kandahar, Afghanistan

Background

Substance use and its associated bio-psycho-social problems are public health concerns with harmful individual and social consequences.

Objective

This study assessed the bio-psycho-social profile of people with substance use disorders (SUD) treated at locally assigned treatment facilities in Kandahar, Afghanistan.

Methods

We conducted this facility-based cross-sectional study among 621 substance users receiving care at three locally assigned treatment facilities in November-December 2022. We performed multiple linear regression to determine factors associated with psychological symptoms.

Results

The mean age of the participants was 34.41 (± 10.10 SD) years. The majority of our subjects (81.2%) perceived their physical health as very good or fair. More than two-thirds (73.4%) rated their social support as high. Of all participants, 541 (87.1%) had symptoms of depression, 569 (91.6%) of anxiety, and 442 (71.2%) of stress. The prevalence of severe depression, anxiety, and stress was 34.8%, 65.8%, and 27.3%, respectively. The multiple linear regression showed that several attributes of people with substance use disorders [ie, having a low level of education (β=0.12, p=<0.001), being unemployed (β=0.31, p=<0.001), having a low level of social support (β=-0.35, p=<0.001), had a pre-existing medical condition (β=-0.28, p=<0.001), and having lived abroad in the past ten years (β=0.10, p=0.001)] were significantly associated with higher DASS-21 total scores.

Conclusion

This study highlights the importance of providing bio-psycho-social support programs and implementing therapeutic interventions to help people with substance use disorders, particularly those who are most susceptible to higher levels of bio-psycho-social problems.

Association of skin autofluorescence with depressive symptoms and the severity of depressive symptoms: The prospective REACTION study

AIM

Millions of people are afflicted by depression, a highly prevalent mental illness with increased morbidity and mortality. Advanced glycation end-products (AGEs) are potential risk factors for depression. We aimed to investigate the correlation of AGEs with depressive symptoms and the severity of depressive symptoms.

METHODS

This study was nested in the prospective REACTION (Risk Evaluation of cAncers in Chinese diabeTic Individuals) study and included 4420 eligible participants. skin autofluorescence (SAF) was used to measure skin AGEs. Depressive symptoms were evaluated by the Self-Rating Depression Scale (SDS). Multiple logistic regression analysis was used to assess the association of AGEs with depressive symptoms and the severity of depressive symptoms.

RESULTS

Logistic analysis showed a significantly positive relationship between quartiles of SAF-AGEs and the risk of depressive symptoms with the OR [95% confidence interval (CI), p value] of 1.24 (95% CI: 1.03-1.50, p = 0.022), 1.39 (95% CI: 1.15-1.68, p = 0.001) and 1.57 (95% CI: 1.28-1.91, p < 0.001) for multivariable-adjusted model respectively. And SAF-AGEs were associated with the severity of depressive symptoms with the multivariable-adjusted OR (95% CI, p value) of 1.06 (95% CI:0.79-1.43, p = 0.681), 1.47 (95% CI: 1.08-1.99, p = 0.014), and 1.54 (95% CI: 1.12-2.11, p = 0.008) respectively. Stratified analyses showed that SAF-AGEs were significantly associated with the severity of depressive symptoms only in females, overweight people, individuals with hypertension, and those without diabetes and insomnia.

CONCLUSIONS

The present study showed that a higher SAF-AGEs level was associated with depressive symptoms and the severity of depressive symptoms.

A latent profile transition analysis and influencing factors of internet addiction for adolescents: A short-term longitudinal study

Internet addiction for adolescent, which is widely concerned by the whole society, has become a public health problem. Internet addiction not only had a negative impact on physical and mental development of adolescents, but also was harmful to their study, life, interpersonal communication and personality formation, and so on. In recent years, the data analysis methods of longitudinal research have developed rapidly. It not only focused on the overall average growth trend, but also considered the differences in the individual trends. Latent profile transition analysis (LPTA) is an extension of latent profile analysis (LPA) and latent transition analysis (LTA), and is a longitudinal data analysis method. LPTA can simultaneously estimate group membership in multiple time points and their latent transition tendency among these subgroups between each two time points. This study used LPTA to explore the development trend of adolescent internet addiction over time and its influencing factors. 1033 adolescents participated in a short-term 6-month longitudinal study with a total of three tests. Participants completed internet addiction test, self-rating anxiety scale and self-rating depression scale. The results showed that: (1) There are three categories of adolescent internet addiction, namely non-internet addiction group, low-internet addiction group and high-internet addiction group. (2) Non-internet addiction group has a strong stability. Low-internet addiction group has a high probability to become non-internet addiction group or high-internet addiction group. (3) Boys are more likely than girls to develop into high-internet addiction group. Anxiety and depression both affect the development of adolescent internet addiction.

Changes in Depression Among Adolescents: A Multiple-Group Latent Profile Transition Analysis

Background

Depression of adolescents is an important public health problem. Persistent depression will become a huge hidden danger of individual mental health development. It is important to study the change mechanism of adolescents' depression.

Methods

A total of 563 males and 739 females aged 11-19 years reported their depression. 1302 adolescents participated in a short-term 6-month longitudinal study. They were contacted every three months for two follow-up tests (T2 and T3). Participants completed internet addiction test, self-rating anxiety scale and self-rating depression scale. Multiple-group latent profile transition analysis (MLPTA) was used to identify meaningful subgroups and transitions between groups across time. Covariates (anxiety and internet addiction) were used to analyze the influencing factors.

Results

The results showed that: (1) There are three categories of adolescents' depression, namely no-depression group, low-depression-mountain group and low-depression-hill group. (2) The depression of the subjects showed a trend of improvement, but the proportion of low-depression-mountain group is relatively high at three time points (0.44, 0.59, and 0.30). (3) The transition probability between the low-depression-mountain group and the no-depression group is large, which suggests the low-depression-mountain group can easily convert into the no-depression group, but the transition probability from low-depression-hill group to other groups is relatively low and stable, which suggests the low-depression-hill group is not easily converted into the no-depression group. (4) Both anxiety and internet addiction affect the development of adolescents' depression across three time points. Anxiety played a significant role in affecting female adolescents' depression, while internet addiction played a significant role in affecting male adolescents' depression.

Conclusion

This study demonstrated a transition pattern in adolescents' depression. We should pay more attention to the low-depression-mountain group and try to do their mental health well. Adolescents' Depression changes rapidly with anxiety and internet addiction for different genders, which suggests that some interventions are needed.

Neuroimaging mechanisms in short-term heroin- and methamphetamine-abstinent users: Similarities and differences

Heroin and methamphetamine cause great damage to individuals and society. However, numerous withdrawal mechanisms remain unidentified. In this study, 19 heroin short-term abstinent (HSTA) patients, 20 methamphetamine short-term abstinent (MSTA) patients, and 27 healthy controls (HCs) were scanned using multimodal magnetic resonance imaging. Degraded nodes of fiber tracts were identified using automated fiber quantification. Voxel- and surface-based morphometric measurements were performed to determine the gray matter volume and cortical thickness. The MSTA and HSTA groups had abnormal diffusion metrics in a variety of bilateral corticospinal tract (CST) and left superior longitudinal tract (SLT) nodes compared with the HC group. The MSTA patients reported more severely disrupted diffusion metrics in certain nodes of the bilateral anterior thalamic radiation and left inferior fronto-occipital tract than the HSTA patients. The MSTA and HSTA groups exhibited identical cortical damage in the fusiform and superior temporal gyri, as well as in the superior frontal gyrus, posterior cerebellum, and precentral gyrus. Extensive differences in gray matter lesions were observed between the MSTA and HSTA groups. Neuroimaging mechanisms of short-term abstinence may aid in the development of rehabilitation strategies.

Cross-border Activities Associated With Pattern of Amphetamine-type Stimulants Usage Among Drug Users in Southwest of China

Cross-border activities are possibly associated with the use of amphetamine-type stimulants (ATS), this study was to explore poly-substance of ATS use and influencing factors among ATS use populations in southwest China. A cross-sectional study was conducted by response driven and continuous samplings from January to July 2021. Descriptive, univariate and logistic regression were carried out. ATS users accounted for 95.6% of the target population, of whom one-third had cross-border experiences with 4.1% of the cross-border purchase of drugs. ATS users were mainly over 31 years old (53.9%), male (98.7%), minority (79.1%), and unmarried (72.7%). Cross-border users consumed more ketamine (8%) and methamphetamine (40%) (P < .05). After adjusting for socioeconomic-demographic factors, cross-border activity [OR: 0.336 (0.141, 0.799)], occupation [OR: 0.273 (0.080, 0.929)], injecting drug behavior [OR: 6.239 (1. 087, 35.811)], frequency [OR: 0.251 (0.073, 0.859)], and ATS use location [OR: 2.915 (1.040, 8.168)] were possible factors influencing ATS use patterns (P < .05). Cross-border activity may be associated with polydrug use, especially predominantly methamphetamine use, among ATS users along the Southwest border. It implied that the focus of drug prevention and control in border areas should be on cross-border populations.

Not Only Excessive Daytime Sleepiness but Also Depression Symptoms, Chronological Age and Onset-Age Were Associated with Impulsivity in Narcolepsy Type 1 Patients

OBJECTIVE

To detect the factors associated with total and subscales impulsivity scores in narcolepsy and further explore the non-linear relationship between these factors and impulsivity score.

METHODS

One hundred and fifty-eight narcolepsy type 1 (NT1) patients were involved in this cross-sectional study. Patients completed questionnaires evaluating impulsivity symptoms (Barratt impulse scale-11, BIS-11), depression symptoms (Center for Epidemiologic Studies Depression Scale for Children, CES-DC or Self-Rating Depression Scale, SDS) and sleepiness (Epworth Sleepiness Scale, ESS). Parameters from polysomnography and multiple sleep latency test were also collected. Linear regression analysis was performed to detect the factors associated with total and subscales impulsivity scores. Then, generalized additive models and smooth curve fitting were performed to explore the non-linear relationship between chronological age and impulsivity scores.

RESULTS

Factors associated with higher total impulsivity score were higher ESS, older onset and adolescents. Factors associated with higher attentional impulsivity score were higher ESS, older onset and adolescents. Factors associated with higher motor impulsivity score were higher ESS, younger onset and depression symptoms. Factors associated with higher non-planning impulsivity score were adolescents, older onset and depression symptoms. A non-linear relationship between age and impulsivity scores (total impulsivity score, attentional impulsivity score and non-planning impulsivity score) was detected in NT1 patients.

CONCLUSION

Not only excessive daytime sleepiness but also onset-age, depression symptoms and chronological age were associated with impulsivity in NT1 patients. The non-linear relationship between age and impulsivity scores suggested brain and mental development alterations in NT1 patients.
