Differences between expressive suppression and cognitive reappraisal in opioids and stimulant dependent patients

Context matters: Exploring the adaptive nature of self-regulation skills in predicting abstinence among veterans with alcohol use disorder

BACKGROUND

Alcohol use disorder (AUD) is highly prevalent among veterans in the United States. Self-regulation skills (e.g., coping and emotion regulation) are important biopsychosocial factors for preventing relapse. However, how variation in self-regulation skills supports abstinence based on contextual demands is understudied in veterans with AUD.

METHODS

In a prospective longitudinal design, treatment-seeking veterans (n = 120; 29 females) aged 23-91 with AUD completed the Alcohol Abstinence Self-Efficacy Scale to assess temptation to drink across several high-risk situations (i.e., negative affect, social/positive emotions, physical concerns, and craving/urges) as well as the Brief-COPE and Emotion Regulation Questionnaire to assess self-regulation skills. Abstinence status was assessed at 6 months. T-tests were used to identify self-regulation skills that differed between abstinent and non-abstinent individuals. Multivariate regression with model selection was performed using all possible interactions between each high-risk situation and the self-regulation skills that significantly differed between groups.

RESULTS

Overall, 33.3% of participants (n = 40; nine females) were abstinent at 6 months. Abstinent individuals reported significantly higher use of suppression (p = 0.015), acceptance (p = 0.005), and planning (p = 0.045). Multivariate regression identified significant interactions between (1) planning and physical concerns (p = 0.010) and (2) acceptance, suppression, and craving/urges (p = 0.007). Greater planning predicted abstinence in participants with higher temptation to drink due to physical concerns (e.g., pain). For individuals with lower temptation to drink due to cravings/urges, simultaneous higher suppression and acceptance increased the likelihood of abstinence. Conversely, for participants with higher cravings, greater acceptance with lower suppression was linked to a higher probability of abstinence.

CONCLUSIONS

Results suggest that the adaptiveness of self-regulation skills in predicting AUD recovery is dependent on contextual demands and highlight the need for culturally sensitive treatments. Collectively, these findings indicate that further research on coping and regulatory flexibility may be an important avenue for tailoring AUD treatment for veterans.

Differences in the associations between psychoactive substance use and alexithymia: A series of Meta-analyses

The present meta-analytic study examined the association between alexithymia and psychoactive substance use. Studies published from 1988 to August 20, 2022 were identified by a systematic search and 168 eligible studies were included in five meta-analyses. Results showed that (1) the correlation between substance use and alexithymia is small but significant (r = 0.177); (2) substance users have substantially higher alexithymia than nonusers (g = 0.545); (3) alexithymic participants have significantly but slightly higher levels of substance use than non-alexithymics (g = 0.242); (4) substance users are significantly but only slightly more likely to be alexithymic than nonusers (OR = 2.392); and (5) alexithymic individuals are not more likely to be substance users than non-alexithymics. Larger effects were observed among samples diagnosed with substance use disorder (SUD), and the use of depressants, alcohol, opiates, and illicit stimulants had stronger relation to alexithymia. We found a tendency for a larger association with problematic use as compared to other indicators (e.g., frequency and duration) of substance use. Among the components of alexithymia, difficulties in identifying feelings has the strongest association with substance use. Our findings support clinical practice by suggesting the improvement of emotion regulation in SUD.

Evaluating the temporal association between the recency of prescribed controlled substance acquisition and fatal and non-fatal opioid overdose

BACKGROUND

Previous studies have explored psychosocial effects as possible triggers of opioid overdose (OOD). However, little is known about the temporal association between OOD and prescribed controlled substance (CS) acquisition.

OBJECTIVE

The objective of this study was to evaluate the temporal relationship between OOD and acquiring prescribed CSs prior to OOD.

METHODS

This study is an exploratory descriptive analysis using Arkansas Prescription Drug Monitoring Program (AR-PDMP) data linked to death certificate and statewide inpatient discharge records. All persons with ≥1 AR-PDMP prescription fill(s) between 1 January 2014 and 31 December 2017 were included (n = 1,946,686). For persons that experienced OOD and had ≥1 PDMP record(s), the difference in days between OOD and the most recent AR-PDMP prescription filled prior to an OOD was recorded. To account for censoring, a sensitivity analysis was conducted restricting the study group to "New AR-PDMP Entrants" that had at least a 180-day gap between consecutive AR-PDMP fill dates.

RESULTS

28,998,307 AR-PDMP records were analyzed for 1,946,686 individuals. 7195 persons experienced 9223 OODs and 414 (4.49%) of those were fatal. Of these, 6236 experienced ≥1 OOD and acquired prescribed CSs prior to or on the day of the first OOD. Of those that experienced ≥1 OOD(s), 2201 (30.59%) had an AR-PDMP record in the 0- to 5-day period prior to their overdose and 497 (6.91%) had an AR-PDMP record the day prior to their overdose. Among New AR-PDMP Entrants that experienced ≥1 OOD(s), 408 (27.38%) had an AR-PDMP record in the 0- to 5-day period prior to their overdose.

CONCLUSION

Though the vast majority of persons accessing CSs in Arkansas did not experience an OOD, a sizable proportion of persons that experience an OOD(s) obtained prescribed CSs immediately prior.

Neurophysiological Deficits During Reappraisal of Negative Emotional Stimuli in Opioid Misuse

BACKGROUND

Opioid misuse is hypothesized to compromise the ability to regulate negative emotions, as manifested through visceral and peripheral physiological signals. However, neurophysiological impairment of top-down cognitive emotion regulation in opioid misuse has not previously been shown.

METHODS

Patients with chronic pain who had been taking opioids for 90 days or longer (N = 149; female, n = 98) underwent a negative emotion regulation task with electroencephalography. Participants were instructed to view or reappraise negative images presented for 3 seconds. Using a validated cutoff score on the Current Opioid Misuse Measure, participants were classified as exhibiting aberrant drug-related behavior consistent with opioid misuse (MISUSE+) or as being low risk for opioid misuse (MISUSE-). Participants reported their craving in response to negative emotions over the past week.

RESULTS

We observed a group × condition interaction (p = .003) such that the MISUSE- group decreased the late positive potential of the electroencephalography during reappraisal, whereas the MISUSE+ group showed increased late positive potential during reappraisal. This deficit in negative emotion regulation remained significant after controlling for an array of potential confounding variables, including opioid dose, pain, and depression. Heightened late positive potential during reappraisal was associated with more severe opioid craving.

CONCLUSIONS

Opioid misuse may occasion top-down deficits in emotional regulation that begin as early as 400 ms after presentation of negative stimuli. It remains unknown whether emotion dysregulation is the cause, correlate, or consequence of opioid misuse. Nonetheless, targeting emotion dysregulation in opioid misuse with reappraisal-focused interventions may represent an important treatment approach.

Mobile phone addiction is associated with impaired cognitive reappraisal and expressive suppression of negative emotion

Previous studies have demonstrated people characterized by mobile phone addiction (MPA) are more prone to emotion regulation difficulties. However, no study has tested the effectiveness of their emotion regulation strategies in experimental conditions. In the present study, by instructing the MPA and control groups to regulate negative emotion through cognitive reappraisal (CR) or expressive suppression (ES), we compared their emotional states in the emotional visual search task after watching a negative emotion evoked video. A multi-factor mixed design of 2(group: MPA/control)×2(emotion regulation strategy: CR/ES)×3(image type: positive expression/negative expression/neutral expression) was conducted. We found the MPA group recognized the negative expression faster than control group after both emotion regulation strategies, indicating ES and CR were both impaired for MPA. The implications of these results were further discussed.

Psychological Determinants of Drug Abuse among Male Adolescents in Isfahan: A Structural Model

Background:

Drug abuse is one of the most prevalent public health problems around the world and Iran too. Drug abuse is influenced by various psychosocial factors. This study aimed to explain the relationship model of drug abuse based on perceived criticism, mindfulness, and emotion regulation in Isfahan male adolescents.

Methods:

This was a correlational cross-sectional study. A total of 350 male students were randomly selected from different high schools in Isfahan during the period of 2015–2016 academic year. Four questionnaires including the probability of drug abuse questionnaire, emotion regulation inventory, Mindful Attention Awareness Scale, and perceived criticism scale were employed. Data were analyzed using Chi-square and correlation coefficient, besides; Structural equation modeling was used to model the direct and indirect relationships between variables. In this regard, SPSS and AMOS softwares were used.

Results:

Out of the whole subjects, 49.7% had score above the median, indicating more likely to be drug abuser. There was a significant correlation between emotional reappraisal (r = −0.40), expressive suppression (r = −0.38), mindfulness (−0.57), and criticism (r = 0.57) with drug abuse among male adolescents (P < 0.001). Moreover, criticism through the emotional self-regulation had indirect effects on drug abuse. Totally 69% of the variance in drug abuse was explained by the study variables.

Conclusions:

In total, the results of this study revealed that high levels of drug abuse among students can be considered as a crucial issue, regarding the significant effects of psychological factors, adaptive emotion-regulation strategies, as well as school and family-based Psycho-social skills, are recommended.

Emotion regulation and motives for illicit drug use in opioid-dependent patients

Refining the mechanisms behind illicit drug use is an important factor for improving the quality of clinical care. Research in alcohol, marijuana, and nicotine use disorders have linked coping motives (e.g. using substances to ameliorate negative emotional states) to problematic substance use. We evaluated the link between emotion regulation difficulties (as assessed via the difficulties in emotion regulation scale [DERS]) and motives for drug use (as assessed via the Drug Use Motives Questionnaire) among individuals (n = 68) with opioid use disorders who were in methadone maintenance treatment. We found that the DERS total score was significantly associated with coping motives for use. Nonacceptance of emotional responses was the only DERS domain that offered nonredundant prediction of coping motives. These findings highlight the relevance of specific emotion regulation deficits in motives for illicit drug use among individuals with opioid use disorders and may help inform targeted cognitive-behavioral treatments in this population.

Emotion dysregulation as a transdiagnostic mechanism of opioid misuse and suicidality among chronic pain patients

BACKGROUND

Chronic pain is a prevalent condition that causes functional impairment and emotional suffering. To allay pain-induced suffering, opioids are often prescribed for chronic pain management. Yet, chronic pain patients on opioid therapy are at heightened risk for opioid misuse-behaviors that can lead to addiction and overdose. Relatedly, chronic pain patients are at elevated risk for suicidal ideation and suicidal behaviors.

MAIN BODY

Opioid misuse and suicidality are maladaptive processes aimed at alleviating the negative emotional hyperreactivity, hedonic hyporeactivity, and emotion dysregulation experienced by chronic pain patients on opioid therapy. In this review, we explore the role of emotion dysregulation in chronic pain. We then describe why emotionally dysregulated chronic pain patients are vulnerable to opioid misuse and suicidality in response to these negative affective states.

CONCLUSION

Emotion dysregulation is an important and malleable treatment target with the potential to reduce or prevent opioid misuse and suicidality among opioid-treated chronic pain patients.

Methamphetamine use and treatment in Iran: A systematic review from the most populated Persian Gulf country

AIM

Methamphetamine use is a new health concern in Iran, the most populated Persian Gulf country. However, there is no well-documented literature. The current study objectives were to systematically review all published English and Persian studies of the prevalence of methamphetamine use, the general physical and psychiatric-related harms and the availability of methamphetamine treatment and harm reduction services for adult users in Iran.

MATERIALS AND METHODS

A comprehensive search of the international peer-reviewed and gray literature was undertaken. Multiple electronic and scientific English and Persian databases were systematically searched from January 2002 to September 2014. Additionally, English and Persian gray literature on methamphetamine use was sought using online gray literature databases, library databases and general online searches over the same period of time.

RESULTS

Nineteen thousand and two hundred and eight studies, reports and conference papers were identified but only 42 studies were relevant to the study objectives. They were mainly published in 2010-2014. The search results confirmed the seizures of methamphetamine (six studies), the prevalence of methamphetamine use among the general population (three studies), drug users (four studies), women (nine studies) and opiate users in opiate treatment programs (five studies). In addition, methamphetamine use had resulted in blood-borne viral infections (one study), psychosis and intoxication (ten studies). Different reasons had facilitated methamphetamine use. However, the Matrix Model, community therapy and harm reduction services (four studies) had been provided for methamphetamine users in some cities.

CONCLUSION

The current situation of methamphetamine use necessitates more research on the epidemiology and health-related implications. These studies should help in identifying priorities for designing and implementing prevention and educational programs. More active models of engagement with Persian methamphetamine users and the provision of services that meet their specific treatment needs are required.
