Abstract
BACKGROUND Anecdotal evidence suggests a substantial proportion of individuals with cocaine use disorder do not report craving during inpatient detoxification. OBJECTIVE To examine prevalence and clinical correlates of consistent absence of cocaine craving among inpatients during detoxification. We hypothesized that craving absence would be associated with less severity of cocaine use, depression, and anxiety. Alternative explanations were also explored. METHODS Craving absence (i.e., non-cravers) was defined as a daily score of zero across two separate craving visual analogue scales in each of the inpatient days. Participants scoring ≥1 on ≥1 day were considered cravers. Severity of cocaine use disorder as well as in-treatment depression and anxiety were assessed. Alternative contributors included presence of cocaine and other substances in urine at admission, in-treatment prescription of psychotropic medications, treatment motivation, executive function, interoception, and social desirability. RESULTS Eighty-seven participants (78.2% males) met criteria as either non-cravers (n = 29; 33.3%) or cravers (n = 58; 66.7%). Mean length of admission in non-cravers and cravers was, respectively, 10.83 and 13.16 days. Binary logistic regression model showed that non-cravers scored significantly lower than cravers on cocaine use during last month before treatment (OR, 95% CI; 0.902, 0.839-0.970), in-treatment depression (OR, 95% CI; 0.794, 0.659-0.956), and in-treatment prescribing of antipsychotics (OR, 95% CI; 0.109, 0.014-0.823). Model prediction accuracy was 88.9%. CONCLUSIONS One in three patients undergoing inpatient detoxification experienced absence of craving, linked to less pretreatment cocaine use, better mood, and decreased administration of antipsychotics. Findings may inform pretreatment strategies and improve treatment cost-effectiveness.

Abstract
BACKGROUND Patient satisfaction with methadone or buprenorphine-naloxone can be multidimensionally and specifically assessed by using, respectively, the Scale to Assess Satisfaction with Medications for Addiction Treatment-Methadone for Heroin addiction (SASMAT-METHER) or the SASMAT-Buprenorphine-Naloxone for Heroin addiction (SASMAT-BUNHER). The factor structures of the SASMAT-METHER and SASMAT-BUNHER show substantial commonalities. The objective of the present study is to evaluate the replicability of the SASMAT-METHER factor structure using data from the SASMAT-BUNHER development study in order to obtain an instrument that can be used to compare patient satisfaction with methadone vs. buprenorphine-naloxone. METHOD Secondary analysis of SASMAT-BUNHER data provided by 205 participants in the original validation study of that scale (Pérez de los Cobos et al., 2018). Using the SASMAT-METHER component solution (17 items, 3 factors) as the target structure, a principal component analysis was performed on the data set comprised of the corresponding 17 SASMAT-BUNHER items using an oblique semi-specified Procrustean rotation. Additionally, Tucker congruence coefficients were computed to examine the correspondence between the two solutions. RESULT The factor structures of SASMAT-METHER and the 17-item version of the SASMAT-BUNHER can be considered equal given that the overall Tucker's congruence coefficient of factorial similarity was 0.972, with individual component congruencies ranging from 0.960 to 0.995. CONCLUSIONS The SASMAT-METHER component solution can serve as a single common tool to compare methadone vs. buprenorphine-naloxone in terms of patient satisfaction. This finding supports the feasibility of using a common metric to specifically assess satisfaction with medications to treat heroin dependence.

Abstract
BACKGROUND Until now, no specific tool has been available to measure heroin-dependent patient satisfaction with buprenorphine-naloxone as a medication. The purpose of the present study was to develop the Scale to Assess Satisfaction with Medications for Addiction Treatment-Buprenorphine-Naloxone for Heroin addiction (SASMAT-BUNHER) and to examine its validity and reliability. METHODS The SASMAT-BUNHER was developed from a pool of 44 self-administered items grouped into nine theoretical domains, as follows: Overall Satisfaction, Pharmacotherapy, Initiation, Anti-Addictive Effect on Heroin, Mental State, Physical State, Personal Functioning, Acceptability, and Anti-Addictive Effect on Secondary Substances. The Treatment Satisfaction Questionnaire for Medication 1.4 version (TSQM 1.4) was used for convergent validation. Participants were 316 heroin-dependent patients in maintenance treatment with buprenorphine-naloxone sublingual tablets at 16 different treatment centres. RESULTS Principal component analysis of the SASMAT-BUNHER revealed a 5-factor structure that accounted for 65.1% of total variance. Based on similarities between empirically-obtained factors and theoretical domains, Factors 1 through 5 were named 'Mental and Physical State' (10 items), 'Anti-Addictive Effect on Other Substances' (5 items), 'Anti-Addictive Effect on Heroin' (4 items), 'Personal Functioning' (3 items), and 'Acceptability' (4 items). All factors showed acceptable internal consistency (Cronbach's alpha coefficients: 0.744-0.925) and test-retest reliability (intraclass correlation coefficients: 0.704-0.895). Correlation between SASMAT-BUNHER and TSQM 1.4 total scores was moderate (Pearson r = 0.552). Moreover, SASMAT-BUNHER total scores of patients reporting absence of buprenorphine-naloxone side effects were higher than those of their counterparts. CONCLUSION These results support the validity and reliability of the SASMAT-BUNHER.

Abstract
BACKGROUND Buprenorphine dosage is a crucial factor influencing outcomes of buprenorphine treatment for heroin use disorders. Therefore, the aim of the present study is to identify naturally occurring profiles of heroin-dependent patients regarding individualized management of buprenorphine dosage in clinical practice of buprenorphine-naloxone maintenance treatment. METHODS 316 patients receiving buprenorphine-naloxone maintenance treatment were surveyed at 16 Spanish centers during the stabilization phase of this treatment. Patients were grouped using cluster analysis based on three key indicators of buprenorphine dosage management: dose, adequacy according to physician, and adjustment according to patient. The clusters obtained were compared regarding different facets of patient clinical condition. RESULTS Four clusters were identified and labeled as follows (buprenorphine average dose and percentage of participants in each cluster are given in brackets): "Clinically Adequate and Adjusted to Patient Desired Low Dosage" (2.60 mg/d, 37.05%); "Clinically Adequate and Adjusted to Patient Desired High Dosage" (10.71 mg/d, 29.18%); "Clinically Adequate and Patient Desired Reduction of Low Dosage" (3.38 mg/d, 20.0%); and "Clinically Inadequate and Adjusted to Patient Desired Moderate Dosage" (7.55 mg/d, 13.77%). Compared to patients from the other three clusters, participants in the latter cluster reported more frequent use of heroin and cocaine during last week, lower satisfaction with buprenorphine-naloxone as a medication, higher prevalence of buprenorphine-naloxone adverse effects and poorer psychological adjustment. CONCLUSIONS Our results show notable differences between clusters of heroin-dependent patients regarding buprenorphine dosage management. We also identified a group of patients receiving clinically inadequate buprenorphine dosage, which was related to poorer clinical condition.

Abstract
OBJECTIVE The Opiate Dosage Adequacy Scale (ODAS) is a clinical tool to individually measure the "adequacy" of opioid doses in patients on maintenance treatment. The aim of this paper is to provide evidence for the validity and reliability of the ODAS in a sample of patients in buprenorphine/naloxone (B/N) maintenance treatment. METHOD Cross-sectional study of a convenience sample of B/N-treated patients (n = 316) from four Autonomous Communities in Spain. Participants completed a battery of instruments to assess the following: buprenorphine dose adequacy; heroin dependence severity; psychological adjustment; and patient-desired adjustment of buprenorphine dose. RESULTS Exploratory Factor Analysis identified four factors from the ODAS that together account for 85.4% of the total variance: "Heroin craving and use"; "Overmedication"; "Objective opiate withdrawal symptoms (OWS)" and 'Subjective OWS'. Compared to patients with an "inadequate" B/N dose (ODAS), patients with "adequate" doses had less heroin use in the last week (0.01 vs. 0.40; t = -2.73; p < 0.01, 95% CI: -0.67, -0.10), less severe heroin dependence (2.20 vs. 5.26, t = -5.14, p < 0.001; 95% CI: -4.23, -1.88), less psychological distress (3.00 vs. 6.31, t = -4.37, p < 0.001; 95% CI: -4.80, -1.81), and greater satisfaction with their doses (42.1% vs. 13.6%, χ2 = 14.44, p < 0.01). Cronbach's alpha coefficient was 0.76 (0.81, 0.92, 0.94, and 0.93, respectively, for the four factor dimensions). CONCLUSION These findings support the validity and reliability of the ODAS as a tool to measure and assess buprenorphine dose adequacy in the context of an opioid dependency treatment program.

Abstract
PURPOSE The aim of the present study was to test a structural equation model of patient satisfaction with different key facets of methadone maintenance treatment (MMT). In this model, the three dimensions of patient satisfaction with methadone as a medication (ie, personal functioning and well-being, anti-addictive effect on heroin, and anti-addictive effect on non-opioid substances) were expected to predict satisfaction with the basic interventions delivered by the staff of treatment centers to implement MMT. PATIENTS AND METHODS A sample of 210 heroin-dependent patients, resistant to MMT treatment (mean age =41.66 years, SD =6.50; 75.7% male), participated voluntarily in this study. Preliminary analysis based on exploratory structural equation modeling supported the expected three-factor measurement model of the scale to assess satisfaction with medications for addiction treatment - methadone for heroin addiction. Moreover, the 15 items measuring staff's basic interventions were shown to be compatible with the expected single-factor measurement model. Then, both measurement models were included in a structural model. RESULTS Results of this model show that patient satisfaction with the compatibility of methadone with personal functioning and well-being, as well as with the anti-addictive effects of methadone on non-opioid substances, predicts satisfaction with basic interventions conducted at methadone treatment centers (β=0.191 and β=0.152, respectively). CONCLUSION Our results provide further understanding regarding patient satisfaction with MMT, which could help professionals to better understand patient perspective and experience during MMT.

Abstract
The present article reviews whether available efficacy and safety data support the pharmacological treatment of adult attention-deficit/hyperactivity disorder (ADHD) in patients with concurrent substance use disorders (SUD). Arguments for and against treating adult ADHD with active SUD are discussed. Findings from 19 large open studies and controlled clinical trials show that the use of atomoxetine or extended-release methylphenidate formulations, together with psychological therapy, yield promising though inconclusive results about short term efficacy of these drugs in the treatment of adult ADHD in patients with SUD and no other severe mental disorders. However, the efficacy of these drugs is scant or lacking for treating concurrent SUD. No serious safety issues have been associated with these drugs in patients with co-morbid SUD-ADHD, given their low risk of abuse and favourable side effect and drug-drug interaction profile. The decision to treat adult ADHD in the context of active SUD depends on various factors, some directly related to SUD-ADHD co-morbidity (e.g. degree of diagnostic uncertainty for ADHD) and other factors related to the clinical expertise of the medical staff and availability of adequate resources (e.g. the means to monitor compliance with pharmacological treatment). Our recommendation is that clinical decisions be individualized and based on a careful analysis of the advantages and disadvantages of pharmacological treatment for ADHD on a case-by-case basis in the context of active SUD.

Abstract
OBJECTIVE To develop and examine the psychometric properties of a scale to specifically assess satisfaction with methadone in heroin-dependent patients. METHODS The 44-item preliminary version of the scale to assess satisfaction with medications for addiction treatment-methadone for heroin addiction (SASMAT-METHER) was obtained from a pool of items designed to assess satisfaction with any medication-addiction combination. Theoretical domains of the initial SASMAT-METHER were overall satisfaction, pharmacotherapy, initiation, anti-addictive effect on heroin, mental state, physical state, personal functioning, acceptability, and anti-addictive effect on secondary substances. The Treatment Satisfaction Questionnaire for Medication 1.4 version (TSQM 1.4) and the Verona Service Satisfaction Scale for Methadone Treatment (VSSS-MT) were used for concurrent validation. Participants included heroin-dependent patients receiving methadone treatment for at least the last 3 months. RESULTS The preliminary version of the SASMAT-METHER scale was completed by 241 patients, with 180 surveys considered suitable for factor analysis. Principal component analysis of these SASMAT-METHER surveys revealed a 3-factor structure that accounted for 40.4% of total variance. Based on similarities between empirically-obtained factors and theoretical domains, factors 1 through 3 were named 'Personal Functioning and Well-Being' (7 items), 'Anti-Addictive Effect on Heroin' (5 items), and 'Anti-Addictive Effect on Other Substances' (5 items). All factors showed good to excellent internal consistency (Cronbach's α: 0.83-0.92) and test-retest reliability (intraclass correlation coefficients: 0.66-0.89). Correlations between overall SASMAT-METHER and TSQM 1.4 scores were stronger (Pearson r=0.69) than correlations between overall SASMAT-METHER and VSSS-MT scores (Pearson r=0.26). CONCLUSION These results present evidence for the validity and reliability of SASMAT-METHER.

Abstract
Reliable and valid assessment of cocaine withdrawal is relevant for treating cocaine-dependent patients. This study examined the psychometric properties of the Spanish version of the Cocaine Selective Severity Assessment (CSSA), an instrument that measures cocaine withdrawal. Participants were 170 cocaine-dependent inpatients receiving detoxification treatment. Principal component analysis revealed a 4-factor structure for CSSA that included the following components: 'Cocaine Craving and Psychological Distress', 'Lethargy', 'Carbohydrate Craving and Irritability', and 'Somatic Depressive Symptoms'. These 4 components accounted for 56.0% of total variance. Internal reliability for these components ranged from unacceptable to good (Chronbach's alpha: 0.87, 0.65, 0.55, and 0.22, respectively). All components except Somatic Depressive Symptoms presented concurrent validity with cocaine use. In summary, while some properties of the Spanish version of the CSSA are satisfactory, such as interpretability of factor structure and test-retest reliability, other properties, such as internal reliability and concurrent validity of some factors, are inadequate.

Abstract
BACKGROUND In the past two decades, there has been a growing interest in the development of a more patient-centred approach to assessing treatment outcomes. This interest has resulted in the increasing use of patient-reported outcome measures (PROMs) in both clinical trials and usual clinical practice. AIMS To briefly discuss the paucity of efficacy and effectiveness studies in the field of mental health (exemplified by schizophrenia, depression and opioid dependence) that significantly incorporate the patient's perspective. The limited concordance between the perspectives of patients and clinicians in outcome assessment is also addressed. Finally, we propose a new PROM classification system based on the degree to which these instruments incorporate the patient's perspective. CONCLUSIONS PROMs may differ little from traditional instruments unless they truly incorporate the patient's perspective and not just the perspectives of clinicians and researchers. Efforts to develop new PROMs that provide a more patient-centred outcome assessment should use qualitative and participatory methods to capture and incorporate patient perspectives and values.

Abstract
Given the benefits that exercise brings to physical and mental health, several authors have investigated its effectiveness as a treatment for various pathologies such as addictive disorders. The aim of this paper is to review the literature regarding the effectiveness of exercise as a complementary intervention for treatment of psychoactive substance dependence. To achieve this aim, a bibliographic search was conducted in the following databases: PubMed, Scopus, ISI Web of Knowledge, The Cochrane Library, TESEO and TDX. Those articles which evaluated the effectiveness of exercise on craving, withdrawal symptoms and abstinence rates were selected. Regarding nicotine dependence, those studies which evaluated the effectiveness of exercise for reducing weight gain after quitting smoking were also chosen. Seventeen articles met the selection criteria. The usefulness of exercise as a complementary strategy along with habitual therapeutic treatments for psychoactive substance dependence seems to be demonstrated, especially in nicotine dependence for the following variables: achieving or maintaining abstinence, and reducing craving or withdrawal symptoms. Further studies are nevertheless required, especially on illegal psychoactive substance dependence to be able to achieve conclusive results. We must also equally note that this kind of intervention is widely accepted by the drug using community, fact that would make of it a particularly useful tool in treating people with addictive disorders.

Abstract
BACKGROUND Patients' satisfaction with methadone maintenance treatment (MMT) is a key measure of treatment quality. The main objective of the present study is to identify independent factors that contribute significantly to satisfaction with MMT. METHOD Participants were a representative sample of methadone-maintained patients (n=123) from the region of La Rioja. Satisfaction with MMT was assessed with the Verona Service Satisfaction Scale for Methadone Treatment (VSSS-MT), and mental health status with the General Health Questionnaire-28 (GHQ-28). Multivariate linear- and logistic-regression analyses were performed to identify variables independently associated with satisfaction with MMT. RESULTS Multiple linear regression analysis revealed that the variables independently associated with VSSS-MT total score were number of hours per week that the centre dispensed methadone (β=0.193), number of patients per centre (β=0.233), perceived frequency of receiving information about methadone dose changes (β=0.246), perceived influence on these changes (β=0.194), and Social Dysfunction subscale of GHQ-28 (β=-0.179). Multivariate binary logistic regression showed that the variables independently associated with the likelihood of being satisfied with MMT were number of years of education completed (OR=0.835), number of patients per centre (OR=1.009), perceived frequency of receiving information about methadone dose changes (OR=1.571), and Social Dysfunction subscale of GHQ-28 (OR=0.748). CONCLUSIONS Patients from larger centres, who perceive themselves as participating to some extent in treatment decisions, and showing lower deterioration in social functioning are more likely to be satisfied with MMT.

Abstract
Background In the last few years there seems to be an emerging interest for including the patients' perspective in assessing methadone maintenance treatment (MMT), with treatment satisfaction surveys being the most commonly-used method of incorporating this point of view. The present study considers the perspective of patients on MMT when assessing the outcomes of this treatment, acknowledging the validity of this approach as an indicator. The primary aim of this study is to evaluate the concordance between improvement assessment performed by two members of the clinical staff (a psychiatrist and a nurse) and assessment carried out by MMT patients themselves. Method Patients (n = 110) and their respective psychiatrist (n = 5) and nurse (n = 1) completed a scale for assessing how the patient's condition had changed from the beginning of MMT, using the Patient Global Impression of Improvement scale (PGI-I) and the Clinical Global Impression of Improvement scale (CGI-I), respectively. Results The global improvement assessed by patients showed weak concordance with the assessments made by nurses (Quadratic-weighted kappa = 0.13, p > 0.05) and by psychiatrists (Quadratic-weighted kappa = 0.19, p = 0.0086), although in the latter, concordance was statistically significant. The percentage of improved patients was significantly higher in the case of the assessments made by patients, compared with those made by nurses (90.9% vs. 80%, Z-statistic = 2.10, p = 0.0354) and by psychiatrists (90.9% vs. 50%, Z-statistic = 6.48, p < 0.0001). Conclusions MMT patients' perception of improvement shows low concordance with the clinical staff's perspective. Assessment of MMT effectiveness should also focus on patient's evaluation of the outcomes or changes achieved, thus including indicators based on the patient's experiences, provided that MMT aim is to be more patient centred and to cover different needs of patients themselves.

Abstract
To characterize those patients with probable adult attention deficit hyperactivity disorder (ADHD) who ask for treatment of cocaine use disorders; to estimate the prevalence of probable adult ADHD among these patients. This is a cross-sectional and multi-center study performed at outpatient resources of 12 addiction treatment centers in Spain. Participants were treatment-seeking primary cocaine abusers recruited consecutively at one center and through convenience sampling at the other centers. Assessments included semi-structured clinical interview focused on Diagnostic and Statistical Manual of Mental Disorders, fourth edition (DSM-IV) ADHD criteria adapted to adulthood, and the Wender-Utah Rating Scale (WURS) for screening childhood history of ADHD according to patients. Probable adult ADHD was diagnosed when patients met DSM-IV criteria of ADHD in adulthood and scored WURS>32. All participants were diagnosed with current cocaine dependence (n=190) or abuse (n=15). Patients with probable adult ADHD, compared with patients having no lifetime ADHD, were more frequently male, reported higher impulsivity, and began to use nicotine, alcohol, cannabis, or cocaine earlier. Before starting the current treatment, patients with probable adult ADHD also showed higher cocaine craving for the previous day, less frequent cocaine abstinence throughout the previous week, and higher use of cocaine and tobacco during the previous month. Impulsivity and male gender were the only independent risk factors of probable adult ADHD in a logistic regression analysis. The prevalence of probable adult ADHD was 20.5% in the sub-sample of patients consecutively recruited (n=78). A diagnosis of probable adult ADHD strongly distinguishes among treatment-seeking cocaine primary abusers regarding past and current key aspects of their addictive disorder; one-fifth of these patients present with probable adult ADHD.

Abstract
The HIV epidemic among injecting drug users (IDUs) has led to greater support for the development of the harm-reduction perspective. This has proven to be a driving force for initially reluctant policy makers, managers and health care providers and has facilitated the implementation of harm-reduction programmes. This article presents recent data, both global and at the European and Spanish levels, about a) the epidemiological situation of HIV infection among IDUs, and b) the state of development of harm-reduction programmes. The incidence of HIV infection among IDUs not only continues to grow in different areas of, for example, Southeast Asia or Eastern Europe, but has even shown an upturn in cities or specific IDU groups in parts of Western Europe with apparently comprehensive harm-reduction strategies. On the other hand, of the 158 countries that acknowledge illegal drug use via injection in their territory, only 82 support harm reduction, explicitly in national policy documents and/or through the implementation or tolerance of interventions such as needle exchange programmes or opioid agonist programmes. These data, in conjunction with the high-quality and consistent evidence on the efficacy and effectiveness of harm- and risk-reduction programmes for HIV prevention and management among IDUs, should serve as a call to avoid complacency with regard to the diversification, accessibility and coverage of harm- and risk-reduction programmes for IDUs.

Abstract
The purpose of this study is to describe the characteristics of a statistical technique appropriate for analysing multi-episode data (multi-episode survival analysis), and to show its application in modelling the flow of readmissions at an inpatient detoxification unit. Data are from 784 opioid-dependent patients admitted at an inpatient detoxification unit, who totalled 1,255 admission episodes. Information stored prospectively at the unit database was reviewed for the following variables at the time of each patient discharge: episode serial number, sex, route of heroin administration, reason for discharge, time of discharge, and transition time (re-entry into the inpatient detoxification unit). Cox's semi-parametric regression model seems the most appropriate for describing the series of episodes. Amongst the parametric models, most noteworthy was the superior fit of the Gompertz-Makeham model, suggesting that the transition rate decreases monotonically with time. The influence of the variables assessed differed based on the serial number of the episode. The results suggest that multi-episode survival analysis is a statistical method that can fully address the long-term perspective on treatment utilization.

Abstract
OBJECTIVE The activity of cytochrome P-450 enzyme 2D6 (CYP2D6) could be related to heroin-dependent patient satisfaction with methadone maintenance treatment. We sought to compare satisfaction with the usual methadone treatment in patients who are ultrarapid, extensive or poor metabolizers, according to CYP2D6 genotyping. METHODS Two hundred and five heroin-dependent patients filled out the Verona Service Satisfaction Scale for methadone maintenance treatment (VSSS-MT), before CYP2D6 genotyping. RESULTS VSSS-MT overall scores were comparable in the poor metabolizer (N=9) and extensive metabolizer (N=185) groups, although they were higher in poor metabolizers and extensive metabolizers taken together than in the ultrarapid metabolizers (N=11) (p<0.003). Likewise, ultrarapid metabolizers scored higher than the rest of the sample on the VSSS-MT Basic Interventions subscale (p<001). Regarding this subscale, no poor metabolizers felt dissatisfied, and ultrarapid metabolizer males (N=7) reported lower satisfaction than ultrarapid metabolizer females (N=4) (p<0.022). Ultrarapid metabolizer genotype accounted for 4.2% of the variance on the VSSS-MT total scores, and 5.0% on the Basic Intervention scores. CONCLUSION Heroin-dependent patients who are CYP2D6 ultrarapid metabolizers according to genotyping present deficient satisfaction with methadone maintenance treatment.

Abstract
The past two decades have been characterized by marked progress in the development of effective cognitive- behavioral therapies for cocaine dependence, for which no generally effective pharmacotherapies have been identified. The increasing literature on the efficacy of several types of cognitive-behavioral therapies (community reinforcement approach plus vouchers, cue exposure treatment, relapse prevention therapy and motivational interviewing) for cocaine use disorders is reviewed, followed by discussion of a number of issues that arise when integrating these cognitive-behavioral interventions into clinical practice. Overall, this review describes a vigorous area of research that has much to contribute to the treatment of cocaine use disorders.
