Emotion regulation in male abstinent heroin abusers

Relationship between anxiety and drug abstention motivation in men with substance use disorders: a cross-sectional study of compulsory isolation rehabilitation in China

Studies have found that anxiety is among the common negative emotions in individuals with substance use disorders. Anxiety affects drug abstention motivation, but the mechanism underlying this effect is still unclear. The current study aimed to examine the relationship among anxiety, regulatory emotional self-efficacy, psychological resilience and drug abstention motivation in an attempt to explore the mechanism underlying drug abstention motivation. The participants were 732 men with substance use disorders who were sent to compulsory rehabilitation in China. All participants completed measures of anxiety, regulatory emotional self-efficacy, psychological resilience and drug abstention motivation through questionnaires. The results indicated that anxiety negatively predicts drug abstention motivation. Regulatory emotional self-efficacy mediates the relationship between anxiety and drug abstention motivation. In addition, psychological resilience moderates the mediation between anxiety and regulatory emotional self-efficacy. The current results are not only helpful for understanding the relationship between anxiety and drug abstention motivation from the perspective of emotion but also of great significance for guiding individuals with substance use disorders in enhancing their drug abstention motivation by reducing negative emotion.

Emotion regulation in substance use disorders: a systematic review and meta-analysis

BACKGROUND AND AIMS

The ability to regulate emotions effectively has been associated with resilience to psychopathology. Individuals with substance use disorders (SUDs) have been shown to have higher levels of negative emotionality, with some evidence suggesting impairment in emotion regulation compared with individuals without SUDs. However, no previous attempt has been made to systematically review the literature to assess the magnitude of this difference. We aimed to assess the association between SUD diagnosis and emotion regulation as measured by the Difficulties in Emotion Regulation Scale (DERS) and Emotion Regulation Questionnaire (ERQ) through a systematic review and meta-analysis of existing findings.

METHODS

The systematic review was conducted using PubMed, PsycINFO and Embase. We examined cross-sectional studies that compared a SUD group with a control group and measured emotion regulation using the DERS or the ERQ. The primary analysis focused on papers using the DERS, as this was the predominant instrument in the literature.

RESULTS

Twenty-two studies met our primary analysis criteria, representing 1936 individuals with a SUD and 1567 controls. Individuals with SUDs relative to controls had significantly greater DERS scores, with a mean difference of 21.44 [95% confidence interval (CI) = 16.49-26.40, P < 0.001] and Hedges' g = 1.05 (95% CI = 0.86-1.24, P < 0.001). The difference was robust, remaining significant after removing outliers and studies with high risk of bias. Individuals with SUDs demonstrated poorer emotion regulation on each subscale of the DERS, with the largest deficits in the Strategies and Impulse subscales. The ERQ analysis revealed greater use of expressive suppression in those with SUDs relative to controls (Hedges' g = 0.76, 95% CI = 0.25-1.28, P = 0.004).

CONCLUSIONS

People with substance use disorders appear to have greater difficulties in emotion regulation than people without substance use disorders.

Abnormal brain oscillations and activation of patients with heroin use disorder during emotion regulation: The role of delta- and theta-band power

BACKGROUND

Emotion dysregulation is a crucial component of substance use disorders in predisposition, maintenance, and relapse. Emotional regulation strategies are an important factor in emotion dysregulation. However, studies on heroin use disorder (HUD) patients' ability to use emotion regulation strategies are scarce.

METHODS

Time-frequency-based analyses were used to compare the power of 33 patients with HUD and 28 healthy controls to elucidate whether patients with HUD have abnormal neural oscillations during passive viewing and emotion regulation strategies. Using the standardized low-resolution brain electromagnetic tomography algorithm (sLORETA), we estimated the possible sources of the anomalous band power.

RESULTS

Compared to patients with HUD, healthy controls showed a stronger decrease in the power of the delta/theta band across all task conditions. The effect peaked at approximately 1300-1900 ms after stimulus onset and varied by task condition. The estimation of sLORETA suggested the frontal, parietal, and limbic lobes as possible generators.

LIMITATIONS

We cannot exclude the potential influence of additional factors, such as sex, depression and anxiety levels, and polysubstance use, on the results.

CONCLUSIONS

Patients with HUD have blunted arousal and impaired ability to use emotion regulation strategies. The abnormal patterns described above may be the underlying neurophysiological basis for this dysfunction. Future studies could combine different approaches to improve emotion dysregulation in patients with HUD to promote treatment outcomes.

Updating Emotional Stimuli in Heroin Abstainers' Working Memory: An Event-Related Potential Investigation

BACKGROUND

It is well-documented that heroin users demonstrate aberrant emotion-processing abilities. However, the mechanism by which heroin users process emotional information after it has captured their attention and entered their working memory is unclear.

OBJECTIVES

A modified emotional 2-back task was used to examine whether heroin abstainers demonstrate specific bias patterns in updating emotional stimuli in their working memory.

METHODS

In total, 26 male heroin abstainers and 29 healthy controls were asked to identify whether the current picture was the same as a picture that had appeared two trials earlier, while behavioral data and electroencephalogram data were collected.

RESULTS

Contrary to predictions, the heroin abstainers and healthy controls demonstrated a similar pattern of P300 activity in response to emotional stimuli with no between-group differences in accuracy or reaction time. More specifically, the P300 amplitudes were larger for negative pictures than for positive and neutral pictures. Surprisingly, we found larger P300 amplitudes at Fz electrodes than at Cz and Pz electrodes in the control group, whereas there was no significant difference at midline electrodes in the heroin abstainers.

CONCLUSIONS/IMPORTANCE

Although subtle differences may exist in attentional engagement toward incoming emotional stimulus between two groups, the similar P300 pattern may indicate partial preservation of emotional working memory capacity associated with adaptive emotion regulation in heroin abstainers. These results deepen our understanding of the emotion regulation impairments associated with chronic drug use.

Direct and indirect associations between perception of childhood trauma and suicidal ideation through emotion dysregulation in males who use heroin

Emotion dysregulation is considered as one of the factors related to suicide in individuals with childhood trauma (CT). However, no research has been performed on the role of emotion dysregulation in the relationship between perception of CT and suicidal ideation in individuals who use heroin. This study aimed to evaluate direct and indirect relationships between perception of CT and suicidal ideation through emotion regulation difficulties (ERD) and cognitive emotion regulation strategies (CERSs) in males with a DSM diagnosis of heroin dependence. In a cross-sectional design, 310 males with a DSM diagnosis of heroin dependence completed the Childhood Trauma Questionnaire-Short Form (CTQ-SF), the Difficulties in Emotion Regulation Scale (DERS), the Cognitive Emotion Regulation Questionnaire-Short version (CERQ-Short), the Obsessive-Compulsive Drug Use Scale-Form Heroin (OCDUS-Form Heroin), and the Depression Anxiety Stress Scales (DASS). The results revealed that perception of CT had no direct relation to suicidal ideation. Perception of CT was indirectly associated with suicidal ideation through some ERD dimensions [e.g., non-acceptance of emotional responses (Non-acceptance), limited access to emotion regulation strategies (Strategies), lack of emotional awareness (Awareness)] and the CERS of positive reappraisal. The findings suggest that high suicidal ideation may stem from a perception of CT and subsequently emotion dysregulation in individuals who use heroin. Also, the findings of this research may have implications for the prevention and treatment of suicidal ideation in individuals using heroin with a perception of CT. The results of the present study require further examination through longitudinal studies.

The role of emotion dysregulation in the relation of childhood trauma to heroin craving in individuals with heroin dependence

OBJECTIVES

Difficulties in emotion regulation (DER) may be important in heroin craving in individuals with heroin dependence who have experienced childhood trauma (CT). However, no research has been performed on DER in the context of heroin dependence. The aim of this study was to evaluate direct and indirect relations of CT to the subscales of heroin craving (i.e., heroin thoughts and interference, intention to use heroin and control of its consumption, and resistance to thoughts and decisions to use heroin) via DER dimensions in individuals with a DSM diagnosis of heroin dependence.

METHODS

In a cross-sectional design, 330 males with heroin dependence completed the Childhood Trauma Questionnaire-Short Form (CTQ-SF), the Difficulties in Emotion Regulation Scale (DERS), the Obsessive-Compulsive Drug Use Scale-Form Heroin (OCDUS-Form Heroin), and the Depression Anxiety Stress Scales (DASS).

RESULTS

The results revealed that CT had no direct relations to the subscales of heroin craving, but it indirectly was related to all three subscales of heroin craving via one of the DER dimensions named limited access to emotion regulation strategies (Strategies) after adjusting for demographic and clinical factors.

CONCLUSIONS

The findings suggest that Strategies may be related to heroin craving in individuals with heroin dependence who have CT. This proposes that treatment and prevention attempts focused on training the use of effective emotion regulation strategies may be useful to reduce heroin craving in individuals with heroin dependence who have experienced a history of CT.

Reappraisal deficits promote craving and emotional distress among chronic pain patients at risk for prescription opioid misuse

Background: A subset of chronic pain patients misuse prescription opioids as a means of regulating negative emotions. However, opioid misuse may result in deficits in emotion regulation strategies like reappraisal by virtue of the deleterious effects of chronic opioid exposure. Aims: The aim of this study was to characterize differences in reappraisal use among chronic pain patients at risk for opioid misuse and those who report taking opioids as prescribed. Methods: A sample of 127 pain patients receiving chronic opioid analgesic pharmacotherapy were classified as at risk for opioid misuse (n = 62) or taking opioids as prescribed (n = 65) using the Current Opioid Misuse Measure (COMM). The Emotion Regulation Questionnaire (ERQ) characterized use of emotion regulation strategies including reappraisal and expressive suppression. Participants also reported levels of opioid craving, emotional distress, and pain severity. Results: Patients at risk for opioid misuse reported significantly less reappraisal use (M = 25.31, SD = 7.33) than those who reportedly took opioids as prescribed (M = 30.28, SD = 7.50), p<.001, but did differ with regard to suppression strategies. Reduced reappraisal use was associated with higher opioid craving and emotional distress that mediated the association between reappraisal deficits and opioid misuse risk. Further, there was a significant indirect effect of opioid misuse on emotional distress via reappraisal use. Discussion: Opioid misuse risk was associated with reduced use of reappraisal, which in turn was associated with dysregulated negative emotions and increased appetitive drive towards consuming opioids. Studying individual differences in emotion regulation may yield efficacious intervention and prevention approaches to stem the rising tide of the prescription opioid crisis.

Emotion regulation strategies in individuals with cocaine use disorder maintained on methadone

BACKGROUND AND OBJECTIVES

Cognitive reappraisal (CR) and emotional suppression (ES), two emotion regulation strategies, are disrupted in other substance use disorders but have not been studied in cocaine dependence.

METHODS

Methadone-maintained individuals with cocaine dependence (N = 72) completed assessment of CR, ES, cocaine use, and psychiatric symptoms.

RESULTS

CR scores were associated with lower depression scores (r = -.29, p = .01), but not with cocaine abstinence during 8 weeks of treatment (r = .12, p = .29).

CONCLUSIONS AND SCIENTIFIC SIGNIFICANCE

CR appeared relevant to cocaine-dependent individuals' depression, but was not associated with abstinence or treatment outcome. (Am J Addict 2016;25:529-532).

Diffusivity of the uncinate fasciculus in heroin users relates to their levels of anxiety

Heroin use is closely associated with emotional dysregulation, which may explain its high comorbidity with disorders such as anxiety and depression. However, the understanding of the neurobiological etiology of the association between heroin use and emotional dysregulation is limited. Previous studies have suggested an impact of heroin on diffusivity in white matter involving the emotional regulatory system, but the specificity of this finding remains to be determined. Therefore, this study investigated the association between heroin use and diffusivity of white matter tracts in heroin users and examined whether the tracts were associated with their elevated anxiety and depression levels. A sample of 26 right-handed male abstinent heroin users (25 to 42 years of age) and 32 matched healthy controls (19 to 55 years of age) was recruited for this study. Diffusion tensor imaging data were collected, and their levels of anxiety and depression were assessed using the Hospital Anxiety and Depression Scale. Our findings indicated that heroin users exhibited higher levels of anxiety and depression, but the heroin use-associated left uncinate fasciculus was only related to their anxiety level, suggesting that association between heroin and anxiety has an incremental organic basis but that for depression could be a threshold issue. This finding improves our understanding of heroin addiction and its comorbid affective disorder and facilitates future therapeutic development.
