RESUMEN
BACKGROUND: Treatment of Substance Use Disorder (SUD) is complex and therefore including patients in the therapeutic process is needed. Patient-Centered Care (PCC) and Shared Decision-Making (SDM) have been associated with greater satisfaction, self-control, and less substance use. However, correlates of SDM have not been investigated in this population. METHOD: A cross-sectional analysis was carried out in 214 SUD patients to identify sociodemographic, clinical and psychological correlates of preferences and perceptions about participation in SDM and degree of activation. The Control Preference Scale (CPS), the Shared Decision-Making Questionnaire (SDM-9-Q) and the Patient Activation Measure (PAM) were used to assess the PCC elements. Multinomial logistic regression was used to analyze the correlates of the CPS variables (preferred role, perceived role, and role matching). For SDM-9-Q and PAM, multilevel linear regression was used. RESULTS: Preferring an active role, compared to a shared one, was significantly associated with higher educational level, lower neuroticism, absence of affective and alcohol use disorders, and higher quality of life. Perceiving greater participation was significantly associated with not being a new patient, having fewer legal problems, higher severity of alcohol consumption, not presenting polydrug use and main substance use different than opioids or sedatives. Activation was associated with higher scores in the personality trait activity, a preference for an active role and greater perception of being involved in the decision process. CONCLUSIONS: Patients with milder clinical profiles prefer an active role compared to a shared one. Patients who prefer or perceive a shared or passive role did not show relevant differences. Greater activation was related to preference for an active role and the perception of having been involved in decisions.

OBJECTIVES: Long-acting injectable buprenorphine (LAIB) has demonstrated a good profile for opioid use disorder (OUD) management. However, there is scarce information on LAIB in OUD patients with comorbid mental disorders (dual disorder patients). METHODS: We present a case report on OUD patients with a comorbid mental disorder who have received LAIB for at least 3 months. RESULTS: Two women and one man with OUD and another comorbid mental disorder were prescribed with LAIB ranging from three to twelve months. Good adherence and opioid abstinence were observed during the follow-up. Psychopathological issues related to comorbid mental disorders were stabilized. A deep discussion on LAIB in this profile of patients is conducted. CONCLUSIONS: LAIB in OUD patients with comorbid mental disorders may be a safe and well tolerated option, similar to OUD patients without comorbid mental disorders. LAIB's impact on psychopathological issues requires further high-quality research to understand the real impact of LAIB on OUD and comorbid mental disorders.
RESUMEN
Background: The COVID-19 pandemic has impacted the mental health of patients with substance use disorder (SUD). However, few longitudinal studies have been done which examine associations between the pandemic, SUD patients' mental health and their drug use. Objectives: This study aimed to examine duration of abstinence according to psychiatric status among SUD outpatients followed-up for 18 months from the pandemic related lockdown. Methods: A follow-up study of 316 SUD outpatients was undertaken. Sociodemographic features, and clinical and consumption related variables were recorded. Pre, during and post lockdown information was evaluated. Abstinence/substance use was monitored at the patient's scheduled follow-up appointments, and psychiatric disorders and psychological variables were revaluated at 18 months. Results: Survival analyses were used to compare the duration of abstinence (in months) from the beginning of the lockdown. It was observed that 70% of patients consumed the main substance for which they were being treated at some point during the follow-up. Men, younger patients, those with more symptoms of anxiety and personality disorders, and patients who experienced increased craving during follow-up, showed shorter duration of abstinence. While patients who had previously maintained at least one year of abstinence, achieved better results. Conclusions: During the first year and a half of the pandemic, SUD outpatients presented alterations in mental health, such us anxiety, depression and maladaptive personality traits and a high rate of relapse. For this reason, despite the health and social crisis and their restrictive measures, a comprehensive treatment should be ensured.
RESUMEN
Patient-centered care in therapeutic processes has been associated with better clinical outcomes, however, it remains a poorly studied aspect in Substance Use Disorder (SUD). The study aimed to evaluate patient's preferences, perceived participation in treatment decisions and activation level; and how they predict retention, pharmacological adherence and substance use during one-year follow-up. Logistic regression models were used to analyze the association between independent variables, along with a wide number of sociodemographic and clinical covariates, and outcomes. Most patients prefer a shared or passive role when making decisions about their treatment, and showed concordance between their preferred and perceived roles. In the univariate models, perceiving more involvement than desired showed a higher likelihood of treatment discontinuation at 12 months, and substance use at 6 and 12 months. No significant associations were found between the remaining decisional variables or the degree of activation with the assessed outcomes. A majority of SUD patients prefer and perceive to be involved in the decision-making process about their treatment. Patients perceiving more involvement than desired might experience an excess of responsibility that could negatively influence treatment continuation and substance use. Limitations of the study preclude any definitive conclusion, and more research is needed to confirm these results.

BACKGROUND: COVID-19 has hindered hepatitis C virus (HCV) and HIV screening, particularly in marginalised groups, who have some of the highest rates of these conditions and lowest rates of COVID-19 vaccination. We assessed the acceptability of combining HCV testing with COVID-19 vaccination in a centre for addiction services (CAS) in Barcelona and a mobile testing unit (MTU) in Madrid, Spain. METHODS: From 28/09/2021 to 30/06/2022, 187 adults from marginalised populations were offered HCV antibody (Ab) testing along with COVID-19 vaccination. If HCV Ab+, they were tested for HCV-RNA. MTU participants were also screened for HIV. HCV-RNA+ and HIV+ participants were offered treatment. Data were analysed descriptively. RESULTS: Findings show how of the 86 CAS participants: 80 (93%) had been previously vaccinated for COVID-19, of whom 72 (90%) had the full first round schedule; none had a COVID-19 vaccine booster and all received a COVID-19 vaccine; 54 (62.8%) were tested for HCV Ab, of whom 17 (31.5%) were positive, of whom all were tested for HCV-RNA and none were positive. Of the 101 MTU participants: none had been vaccinated for COVID-19 and all received a COVID-19 vaccine; all were tested for HCV Ab and HIV and 15 (14.9%) and 9 (8.9%) were positive, respectively; of those HCV Ab+, 9 (60%) were HCV-RNA+, of whom 8 (88.9%) have started treatment; 5 (55.6%) of those HIV+ had abandoned antiretroviral therapy, of whom 3 (60%) have re-started it. CONCLUSIONS: The intervention was accepted by 54 (62.8%) CAS participants and all MTU participants and can be used in marginalised communities.
The COVID-19 pandemic has reduced the numbers of people being screened to determine whether they are infected with the hepatitis C virus (HCV) or HIV. This is particularly the case for marginalised populations, which include people with substance use disorders (e.g., injecting drug use), those who are experiencing homelessness, and those with mental health disorders. This study explored whether these populations were willing to be tested for HCV after receiving a COVID-19 vaccination in a centre for addiction services in Barcelona and a mobile testing unit (MTU) in Madrid, Spain. Those attending the MTU were also screened for HIV. Most participants were both vaccinated and tested for HCV and HIV, as applicable, when offered. Applying this approach more widely could improve healthcare reach among marginalised populations.
RESUMEN
Suicidal behaviors are common among patients with substance use disorders (SUD). However, the prevalence and clinical factors related to suicide behaviors among patients who have had substance-induced psychosis (SIP) is unknown. This study aims to explore the prevalence, clinical features, and factors related to lifetime suicidal ideation (SI) and suicide attempts (SA) in patients who have had SIP across their lifetime. A cross-sectional study was conducted in an outpatient center for addiction treatment between 01/01/2010 and 12/31/2021. 601 patients were evaluated with validated scales and questionnaires (79.03% males; M age 38.11±10.11 years). The prevalence of SI and SA was 55.4% and 33.6%, respectively. SI was independently related to any type of lifetime abuse, depressive spectrum disorders, benzodiazepine use disorder, borderline personality disorder, and the level of depressive symptoms. SA was independently associated with lifetime physical abuse, benzodiazepine use disorder, the number of psychotic symptoms, borderline personality disorder, and the level of depressive symptoms. The main factors related to SI and SA in those patients should be evaluated in daily clinical practice and considered in any approach to clinical practice as well as in health policies targeting suicide prevention.

OBJECTIVE: This study aims to assess the validity of the ADHD module of the Mini-International Neuropsychiatric Interview (MINI-Plus) in patients with substance use disorders (SUD), using the Conners' Adult ADHD Diagnostic Interview for DSM-IV (CAADID) as the external criterion. METHOD: A cross sectional international multi-center study in 10 countries was conducted in treatment seeking SUD patients. A sample of 1263 patients with both MINI-Plus and CAADID was analyzed to determine the psychometric properties of the MINI-Plus. RESULTS: According to the CAADID, 179 patients (14.2%) met criteria for adult ADHD, whereas according to the MINI-Plus 227 patients (18.0%) were identified as having adult ADHD. Sensitivity of the MINI-Plus ADHD module was 74%, specificity was 91%, positive predictive value was 60% and negative predictive value was 96%. Kappa was 0.60. CONCLUSION: The MINI-Plus has acceptable criterion validity for the screening of adult ADHD in treatment seeking SUD patients. SCIENTIFIC SIGNIFICANCE: On the basis of the results, The MINI-Plus may be used for the screening of ADHD in SUD patients.

Problematic Gambling or Gambling Disorder (GD) can act by initiating and maintaining the problem of substance addiction. Despite this, there are no rapid screening tools validated in Spanish. The Brief Problem Gambling Screen (BPGS) has proven to be one of the most sensitive tools for detecting GD and populations at risk. This study aims to validate the Spanish version of the original five-item BPGS. A sample of 100 Spanish-speaking adults with substance use disorder were recruited from an addiction treatment center. The participants were administered the Spanish version of BPGS. It showed strong item reliability properties (Ω = 0.93). Sensitivity and specificity values were excellent (0.93 each), also positive (0.7) and negative (0.99) predictive values suggest high discriminant power when compared to non-GD subjects. Statistically significant strong correlation with a gold-standard measure (Problem Gambling Severity Index) was found (r = 0.8, p < 0.01). Similar psychometric properties were found in at-risk gambler patients. In conclusion, the BPGS seems to be an adequate screening instrument in Spanish-speaking clinical population, and also identifies at-risk of GD subjects.
El juego patológico (JP) puede actuar iniciando y manteniendo el problema de la adicción a sustancias. A pesar de ello, no existen herramientas de cribado rápido validadas en español. La Breve evaluación del juego problemático (BPGS) ha demostrado ser una de las herramientas más sensibles para detectar JP y poblaciones en riesgo. Este estudio tiene como objetivo validar la versión en español de la BPGS original de cinco factores. Se reclutó una muestra de 100 adultos hispanohablantes con trastorno por uso de sustancias de un centro de tratamiento de adicciones. A los participantes se les administró la versión en español de la BPGS. El instrumento mostró propiedades de fiabilidad de los ítems evaluados (Ω = 0,93). Los valores de sensibilidad y especificidad fueron excelentes (0,93 cada uno), también los valores predictivos positivos (0,7) y negativos (0,99) sugieren un alto poder discriminante en comparación con los sujetos sin JP. Se encontró una fuerte correlación significativa con la medida gold-estándar (índice de severidad del juego problemático, PGSI) (r = 0,8, p < 0,01). Se encontraron propiedades psicométricas similares en pacientes en riesgo de JP. En conclusión, la BPGS parece un buen instrumento de cribado en la población clínica española, y también identifica a los sujetos en riesgo de desarrollar JP.
RESUMEN
BACKGROUND: Substance use disorders (SUD) often co-occur with attention deficit hyperactivity disorder (ADHD). Although the short-term effects of some specific interventions have been investigated in randomized clinical trials, little is known about the long-term clinical course of treatment-seeking SUD patients with comorbid ADHD. AIMS: This paper presents the protocol and baseline clinical characteristics of the International Naturalistic Cohort Study of ADHD and SUD (INCAS) designed and conducted by the International Collaboration on ADHD and Substance Abuse (ICASA) foundation. The overall aim of INCAS is to investigate the treatment modalities provided to treatment-seeking SUD patients with comorbid ADHD, and to describe the clinical course and identify predictors for treatment outcomes. This ongoing study employs a multicentre observational prospective cohort design. Treatment-seeking adult SUD patients with comorbid ADHD are recruited, at 12 study sites in nine different countries. During the follow-up period of nine months, data is collected through patient files, interviews, and self-rating scales, targeting a broad range of cognitive and clinical symptom domains, at baseline, four weeks, three months and nine months. RESULTS: A clinically representative sample of 578 patients (137 females, 441 males) was enrolled during the recruitment period (June 2017-May 2021). At baseline, the sample had a mean age (SD) of 36.7 years (11.0); 47.5% were inpatients and 52.5% outpatients; The most prevalent SUDs were with alcohol 54.2%, stimulants 43.6%, cannabis 33.1%, and opioids 14.5%. Patients reported previous treatments for SUD in 71.1% and for ADHD in 56.9%. Other comorbid mental disorders were present in 61.4% of the sample: major depression 31.5%, post-traumatic stress disorder 12.1%, borderline personality disorder 10.2%. CONCLUSIONS: The first baseline results of this international cohort study speak to its feasibility. Data show that many SUD patients with comorbid ADHD had never received treatment for their ADHD prior to enrolment in the study. Future reports on this study will identify the course and potential predictors for successful pharmaceutical and psychological treatment outcomes. TRIAL REGISTRATION: ISRCTN15998989 20/12/2019.

Objective: Agitation in patients diagnosed with personality disorders (PD) is one of the most frequent crises in emergency departments (ED). Although many medications have been tested, their effectiveness has been small or non-significant, and no specific drugs are supported by the available evidence. This study aimed to evaluate the efficacy of Inhaled loxapine (IL) as a therapeutic option for agitated patients with PD. Methods: A naturalistic, unicentric, prospective study was carried out. Thirty subjects diagnosed with PD and attending the ED with episodes of agitation were recruited most of whom were women diagnosed with Borderline Personality Disorder. Subjects were treated with a single dose of IL (9.1 mg). Efficacy was assessed with the Clinical Global Impression scale, the Excited Component of the Positive and Negative Syndrome Scale (PANSS-EC) and the Agitation-Calmness Evaluation Scale (ACES). Patients were followed 60 minutes after administration to measure IL effect and its duration. Results: IL exhibited an overall efficacy in managing mild to severe agitation, with a quick onset of effect and persistence. 'Effect of time', where IL efficacy is maintained over time, is more marked in higher-severity agitation. No additional treatments were needed to improve agitation during the follow-up time. Conclusion: Results suggest that IL could be a safe and effective option to manage agitation in PD.
RESUMEN
INTRODUCTION: COVID-19 has had a great impact on mental health in the general population. However, few studies have focused on patients with substance use disorders (SUDs). This research aimed to compare the clinical status and substance use patterns of SUD outpatients, before and during confinement due to the COVID-19 pandemic. METHODS: This multicentre study recruited 588 patients (29.2% women; M age = 47.4 ± 11.7 years) in thirteen centres for addiction treatment in Catalonia, Spain. All subjects were evaluated with validated instruments and ad hoc questionnaires. The sample was divided into 3 groups according to how the substance consumption pattern changed during lockdown (maintained pattern, worsened pattern, and improved pattern). RESULTS: More than 62% of the patients maintained or worsened their consumption pattern during confinement, and about 38% improved throughout this time. Diverse factors were associated with the changes in pattern like age, addiction severity, psychological distress during lockdown, social and familial issues, and therapeutic variables. CONCLUSION: The home lockdown during the COVID-19 pandemic was associated with major implications for substance consumption and psychiatric distress among SUD outpatients. Considering this, the need to plan appropriate interventions in cases of similar health crises is highlighted.

BACKGROUND: Hepatitis C virus (HCV) management is a challenge in patients with substance use disorder (SUD). This study aimed to describe an HCV screening and linkage to care program in SUD patients, and analyze the characteristics of this population in relation to HCV infection, particularly the impact of psychiatric comorbidities (dual diagnosis). METHODS: This study was a prospective clinical cohort study using a collaborative, multidisciplinary model to offer HCV care (screening, diagnosis, and therapy) to individuals with SUD attending a dedicated hospital clinic. The characteristics of the participants, prevalence of HCV infection, percentage who started therapy, and adherence to treatment were compared according to the patients' consumption characteristics and presence of dual diagnosis. HCV screening, diagnosis, treatment initiation, and sustained virologic response were analyzed. RESULTS: 528 individuals attended the center (November 2018-June 2019) and 401 (76%) accepted screening. In total, 112 (28%) were anti-HCV-positive and 42 (10%) had detectable HCV RNA, but only 20 of the latter started HCV therapy. Among the 253 (63%) patients with a dual diagnosis, there were no differences in HCV infection prevalence versus patients with SUD alone (p = 0.28). Dual diagnosis did not lead to a higher risk of HCV infection or interfere with linkage to care or treatment. CONCLUSION: This study found a high prevalence of dual diagnosis and HCV infection in SUD patients, but dual diagnosis was not associated with an increased risk of acquiring HCV or more complex access to care. Despite use of a multidisciplinary management approach, considerable barriers to HCV care remain in this population that would need more specific focus.
RESUMEN
OBJECTIVE: Cannabis and synthetic cannabinoids (SC) are related to several neuropsychiatric symptoms and disorders, especially psychotic symptoms and disorders. Interestingly, catatonia-like symptoms associated with cannabis and SC have been generally neglected in research and scarcely described despite the clinical repercussions. Hence, this review aims to analyze current clinical publications on catatonia induced by cannabis or SC in a systematized way. Methods: A search using PRISMA guidelines was performed on three databases based on a specific inclusion and exclusion criteria. Results: 11 publications describing 14 patients (10 males; mean age 22.50 ± 6.67 years old) with catatonia apparently precipitated by the use of cannabis (n = 6) or SC (n = 8) were found. Clinical features and treatment are described and discussed. Conclusion: From a clinical perspective, cannabis and SC use may be related to catatonia-like symptoms and catatonia syndrome in the same way these substances (cannabis and SC) are related to induced-psychotic episodes. However, further research will be required to understand the exact nature of that relationship. Additionally, investigations focused on the clinical significance (i.e., prognosis, evolution, and outcomes) of catatonia-like symptoms induced by cannabis and SC use in patients are also needed.

Ayahuasca is a psychotropic infusion prepared by boiling the bark of Amazonian plants and has many psychopharmacological effects not fully understood. Some of those effects are used as treatment for different diseases. However, the side effects of ayahuasca, including ayahuasca-induced psychosis, are an important issue. Here we report the case of a patient who had a psychotic episode after taking ayahuasca and who was successfully treated with antipsychotic medication. Given the current spread of ayahuasca consumption in developed societies, the present case highlights the need for better understanding and regulation of the social-legal condition of ayahuasca and the need for further research. Additionally, psycho-education seems advisable in order to create awareness of the potential risks of the use of ayahuasca.
RESUMEN
INTRODUCTION: Improving the knowledge and attitudes of people facing an opioid overdose is one of the key prevention measures for reducing overdose occurrence and severity. In this respect, the Opioid Overdose Knowledge Scale (OOKS) and Opioid Overdose Attitudes Scale (OOAS) have been developed and validated in English to assess and improve knowledge and attitudes of opioid users and their families and care providers, in case of an overdose. Here, the OOKS and OOAS scales have been translated into French, Spanish, and German, and the different versions of the 2 scales have been assessed regarding their psychometric properties. METHODS: The translation procedure of the scales was based on the international recommendations, including a back translation by a native English speaker. Subsequently, 80 (Spain: 29, France: 27, Germany: 24) former or current heroin users, aged from 20 to 61 years (M = 39.4 ± 9.23), completed the OOKS and OOAS versions of their native language, in test-retest, without specific between-assessment training. Internal consistency was assessed using Cronbach's α, while test-retest reliability was assessed using intraclass correlation coefficient (ICC). The correlation between the OOKS and OOAS scores of a same language was assessed using Spearman's (ρ) coefficient. RESULTS: Internal consistency of the OOKS was found to be good to very good, with Cronbach's α ranging from 0.62 to 0.87. Test-retest reliability was also very good, with ICCs ranging from 0.71 to 0.82. However, results were less reliable for the OOAS, as internal consistency was questionable to acceptable, with Cronbach's α ranging from 0.12 to 0.63, while test-retest ICCs were very good for the French (0.91) and Spanish (0.99) versions and barely acceptable for the German version (0.41). No significant correlation was found between the OOKS and OOAS scores, irrespective of the version concerned. CONCLUSION: While satisfactory results were found for the 3 versions of the OOKS, results on the OOAS were relatively inconsistent, suggesting a possible gap between knowledge and attitudes on overdose among opioid users.

RESUMEN La ayahuasca es una bebida psicotrópica preparada a través de la cocción de plantas de la cuenca amazónica que tiene muchos efectos psicofarmacológicos no del todo estudiados. Algunos de esos efectos son usados como tratamiento de diversas patologías. Sin embargo, existen efectos secundarios de la ayahuasca que deben ser tenidos en cuenta, entre ellos psicosis inducida por ayahuasca. Reportamos un caso de un paciente que, tras autoadministración de ayahuasca, presentó un episodio psicótico y que fue satisfactoriamente tratado con antipsicóticos. Dada el uso cada vez más frecuente de ayahuasca en las sociedades desarrolladas, el caso actual resalta las necesidades de entender, regular e investigar el uso de la ayahuasca. Además, crear conciencia de los potenciales riesgos del uso de ayahuasca a través de la psicoeducación debería ser implementado.

INTRODUCTION: The impact of psychiatric comorbidity and addiction features throughout the course of addiction has been widely studied. This is a naturalistic study conducted in an outpatient unit, where treatment follow-up studies are scarce compared to studies including inpatients or those under experimental conditions. Therefore, this follow-up study aims to analyze the treatment adherence and abstinence of outpatients with SUD (Substance Use Disorders) according to addiction severity and psychiatric comorbidity. METHODS: The current six-month follow-up study examined 404 SUD outpatients. Psychiatric comorbidity, addiction severity, substance consumption and treatment adherence were systematically evaluated using semistructured interviews. Survival analyses were conducted to compare the time of treatment adherence and abstinence in a bivariate and multivariate level. RESULTS: A progressive dropout was observed, reaching 32.2% of dropouts at the six-month follow-up. More than 50% achieved abstinence during the first month and similar percentages were found until the six-month follow-up. At the multivariate level, treatment adherence, cannabis use disorder and polyconsumption were independently associated with earlier dropout. ADHD was the only mental disorder significantly related with dropout. Regarding substance consumption, the time of abstinence was independently associated with months of treatment adherence and the achievement of abstinence before starting treatment. In general, dual diagnosis was associated with less time of abstinence, but only depressive disorder across the lifespan was related to less time of abstinence in the multivariate model. CONCLUSION: These findings highlight the importance of an accurate diagnosis at the beginning of treatment, especially in an outpatient setting, addressing the treatment needs and promoting strategies that improve treatment adherence and reduce the risk of relapses.

Drug dependence is a neuropsychiatric condition that involves genetic, epigenetic and environmental factors. Allele-specific methylation (ASM) is a common and stable epigenetic mechanism that involves genetic variants correlating with differential levels of methylation at CpG sites. We selected 182 single-nucleotide polymorphisms (SNPs) described to influence cis ASM in human brain regions to evaluate their possible contribution to drug dependence susceptibility. We performed a case-control association study in a discovery sample of 578 drug-dependent patients (including 428 cocaine-dependent subjects) and 656 controls from Spain, and then, we followed-up the significant associations in an independent sample of 1119 cases (including 589 cocaine-dependent subjects) and 1092 controls. In the discovery sample, we identified five nominal associations, one of them replicated in the follow-up sample (rs6020251). The pooled analysis revealed an association between drug dependence and rs6020251 but also rs11585570, both overcoming the Bonferroni correction for multiple testing. We performed the same analysis considering only cocaine-dependent patients and obtained similar results. The rs6020251 variant correlates with differential methylation levels of cg17974185 and lies in the first intron of the CTNNBL1 gene, in a genomic region with multiple histone marks related to enhancer and promoter regions in brain. Rs11585570 is an eQTL in brain and blood for the SCP2 and ECHDC2 genes and correlates with differential methylation of cg27535305 and cg13461509, located in the promoter regions of both genes. To conclude, using an approach that combines genetic and epigenetic data, we highlighted the CTNNBL1, SCP2 and ECHDC2 genes as potential contributors to drug dependence susceptibility.

Alexithymia is related to a higher severity of substance use disorders (SUD); however, few longitudinal studies have been performed on how alexithymia impacts treatment outcomes. This study aims to evaluate alexithymia as a factor that could influence retention and the time of the first relapse in a one-year follow-up in an outpatient treatment center for SUD. In total, 126 SUD outpatients (74.60% males; M age = 43.71, SD = 14.61 years) were evaluated at baseline with an AdHoc questionnaire for sociodemographic variables, the European Addiction Severity Index (EuropASI), the Semi-structured Clinical Interview for Axis I and Axis II Disorders of the DSM-IV, and the Toronto Alexithymia Scale (TAS-20). The prevalence of alexithymia was 41.3% and the mean score of TAS-20, was 57.27 (SD = 12.84). At baseline, alexithymia was related to a lower education level, cannabis use disorder, the psychological item of EuropASI, and mood spectrum disorders. In the Kaplan-Meier analysis, SUD patients with alexithymia were in treatment for less time and presented earlier relapses than non-alexithymic patients. In the Cox regression, alexithymia was only associated with less time in treatment. Therefore, alexithymia may have an important role in the outcomes of SUD treatment, and hence, therapeutic approaches for SUD that cover emotional impairments associated with alexithymia should be investigated and developed.

Background: Insomnia is highly prevalent in patients with substance use disorders (SUD), and it has been related to a worse course of addiction. Insomnia during detoxification in a hospital has not been adequately studied. This study aims to compare sociodemographic, clinical, and psychopathological characteristics of SUD patients undergoing a detoxification program, by comorbidity and insomnia symptoms. Methodology: We recruited 481 patients who received pharmacological and psychotherapeutic treatment for detoxification. They were evaluated through semi-structured interviews, standardized questionnaires, and a specific sleep log. A bivariate and multivariate analysis of the data was performed. Results: Insomnia was reported by 66.5% patients, with sleep-maintenance insomnia the most frequent issue, followed by early morning awakening and sleep-onset insomnia. Patients with alcohol use disorder and cannabis use disorder had higher prevalence of sleep-onset insomnia. Patients with cocaine and heroin use disorder had higher prevalence of sleep-maintenance insomnia. Independent factors that allowed the identification of insomnia symptoms included being female (OR: 3.43), polysubstance use (OR: 2.85), comorbid anxiety disorder (OR: 2.02), and prior admission for detoxification (OR: 1.22). Conclusions: Insomnia symptoms are very prevalent in patients admitted for detoxification. The diagnosis and therapeutic strategies for the insomnia symptoms should be improved, especially in women and in patients with greater addiction severity and with anxiety disorders.
