Virtual Digital Psychotherapist App-Based Treatment in Patients With Methamphetamine Use Disorder (Echo-APP): Single-Arm Pilot Feasibility and Efficacy Study.

BACKGROUND: Substance use disorder is one of the severe public health problems worldwide. Inequitable resources, discrimination, and physical distances limit patients' access to medical help. Automated conversational agents have the potential to provide in-home and remote therapy. However, automatic dialogue agents mostly use text and other methods to interact, which affects the interaction experience, treatment immersion, and clinical efficacy. OBJECTIVE: The aim of this paper is to describe the design and development of Echo-APP, a tablet-based app with the function of a virtual digital psychotherapist, and to conduct a pilot study to explore the feasibility and preliminary efficacy results of Echo-APP for patients with methamphetamine use disorder. METHODS: Echo-APP is an assessment and rehabilitation program developed for substance use disorder (SUD) by a team of clinicians, psychotherapists, and computer experts. The program is available for Android tablets. In terms of assessment, the focus is on the core characteristics of SUD, such as mood, impulsivity, treatment motivation, and craving level. In terms of treatment, Echo-APP provides 10 treatment units, involving awareness of addiction, motivation enhancement, emotion regulation, meditation, etc. A total of 47 patients with methamphetamine dependence were eventually enrolled in the pilot study to receive a single session of the Echo-APP-based motivational enhancement treatment. The outcomes were assessed before and after the patients' treatment, including treatment motivation, craving levels, self-perception on the importance of drug abstinence, and their confidence in stopping the drug use. RESULTS: In the pilot study, scores on the Stages of Change Readiness and Treatment Eagerness Scale and the questionnaire on motivation for abstaining from drugs significantly increased after the Echo-APP-based treatment (P<.001, Cohen d=-0.60), while craving was reduced (P=.01, Cohen d=0.38). Patients' baseline Generalized Anxiety Disorder-7 assessment score (ß=3.57; P<.001; 95% CI 0.80, 2.89) and Barratt Impulsiveness Scale (BIS)-motor impulsiveness score (ß=-2.10; P=.04; 95% CI -0.94, -0.02) were predictive of changes in the patients' treatment motivation during treatment. Moreover, patients' baseline Generalized Anxiety Disorder-7 assessment score (ß=-1.607; P=.03; 95% CI -3.08, -0.14), BIS-attentional impulsivity score (ß=-2.43; P=.004; 95% CI -4.03, -0.83), and BIS-nonplanning impulsivity score (ß=2.54; P=.002; 95% CI 0.98, 4.10) were predictive of changes in craving scores during treatment. CONCLUSIONS: Echo-APP is a practical, accepted, and promising virtual digital psychotherapist program for patients with methamphetamine dependence. The preliminary findings lay a good foundation for further optimization of the program and the promotion of large-scale randomized controlled clinical studies for SUD.

Effectiveness of Mindfulness - Based Therapy and Counseling programs (MBTC) on relapses to methamphetamine dependence at a substance dependency treatment center.

This non-concurrent controlled intervention study aimed to examine the effectiveness of the Mindfulness - Based Therapy and Counseling programs (MBTC) on the treatment of methamphetamine use disorder among 70 individuals (37 females) receiving methamphetamine dependency treatment. Participants were divided into a control group undergoing the usual program and an experimental group using MBTC plus the usual program at a treatment center in Thailand. The study was conducted using the Methamphetamine Craving Questionnaire, urine Color Immunochromatographic Assay and the Mini-International Neuropsychiatric Interview. Stress, depression, and mindfulness were also assessed. MBTC comprised of practicing mindfulness for 90-120 min weekly for eight weeks. Participants were assessed before and after the treatment(s) and at follow-ups visits at 2, 4, 8, 12, and 24 weeks. Mean age (30.3 ± 5.8 years), age of first methamphetamine use (18.2 ± 4.5 years) and other demographics did not differ between groups. At six-month follow-up, the experimental group had significantly lower craving (-7.89, 95%CI = -15.47, -0.32), stress (-7.44, 95%CI = -12.21, -2.67), and depression (-2.95, 95%CI = -5.31, -0.6) and statistically significant higher mindfulness scores (12.86, 95%CI = 9.37, 16.35) than the control group. In addition, methamphetamine relapse in the MBTC group (5/35, 14.3%) was significantly lower than the control group (16/35, 45.7%).

Four-week Tai Chi intervention decreases attention bias to drug cues in individuals with methamphetamine use disorder.

Background: Mind-body exercise is used for the rehabilitation of individuals with methamphetamine use disorder (MUD). Attention bias to substances is an important index of MUD. However, whether a mind-body exercise intervention can decrease attention bias is unclear.Objective: This study aimed to test the effect of a four-week Tai Chi (a Chinese traditional mind-body exercise) exercise program on the attention bias of individuals with MUD.Methods: Thirty-two men with MUD and without Tai Chi practice experience were recruited and randomly assigned to either a Tai Chi exercise group or a control group. The Tai Chi group received four-week Tai Chi training, while the control group engaged in daily exercise (including radio gymnastics and Jianxincao, two kinds of free-hand exercises). During a drug-related Stroop task, participants were instructed to respond to the color of the word ignoring the word type (drug-related or neutral words). The reaction time and d' (the index of sensitivity) were measured.Results: The participants showed attention bias to substance cues; the reaction time was slower for drug-related words than for neutral words (p < .05). After the Tai Chi intervention, the Tai Chi group showed a faster reaction time (ps < .05) and a smaller d' (ps < .05) than the baseline across all the word types. In contrast, the control group showed no differences (ps > .05).Conclusion: Four-week Tai Chi intervention reduced sensitivity and attentional bias to drug-related cues in individuals with MUD, suggesting that mind-body exercise might enhance recovery from MUD via attention control.

A mindfulness-based, stress and coping model of craving in methamphetamine users.

There is increasing interest in the role of mindfulness and mindfulness-based interventions to optimize recovery from a substance use disorder (SUD). However, relatively little is known about the theory-based psychological and social pathways whereby mindfulness could have beneficial effects for managing a chronic, relapsing SUD. Informed by Revised Stress and Coping Theory, the present cross-sectional study examined affective, cognitive, and social pathways whereby mindfulness is associated with lower methamphetamine craving. A total of 161 HIV-positive, methamphetamine-using sexual minority men completed a screening visit for a randomized controlled trial. Using a hybrid structural equation model, we examined pathways whereby mindfulness is associated with lower methamphetamine craving. We found that greater mindfulness was directly associated with lower negative affect and higher positive affect as well as indirectly associated with less methamphetamine craving. Interestingly, the indirect association between mindfulness and methamphetamine craving appeared to be uniquely attributable to positive affect. Only positive affect was indirectly associated with lower methamphetamine craving via higher positive re-appraisal coping and greater self-efficacy for managing triggers for methamphetamine use. Methamphetamine craving was supported by moderate associations with greater substance use severity and more frequent methamphetamine use. These findings support the role of mindfulness in cultivating positive affect, which could be crucial to build the capacity of individuals to manage methamphetamine craving as a chronic stressor that threatens recovery from SUD.

Lack of longitudinal changes in cognition in individuals with methamphetamine use disorder during the first 6 weeks after commencing treatment.

Background: Methamphetamine use disorder (MUD) associates with cognitive impulsivity deficits. However, few studies have examined longitudinal changes in cognition, and it remains unclear if deficits resolve during early recovery.Objectives: To compare: (1) cognitive function of individuals with MUD at treatment onset and six-weeks later with controls tested over the same period; (2) cognitive changes in MUD-individuals who remained abstinent versus relapsed.Method: We recruited 108 participants meeting DSM-IV-TR criteria for methamphetamine dependence (81 males) and 50 demographically matched controls (38 males); 77 methamphetamine- dependent participants (59 males) and 48 controls (36 males) were retained at follow-up. We administered response inhibition, delay discounting and uncertainty-based decision-making tests at both endpoints. Relapse was defined as methamphetamine concentrations >0.4 ng/mg at follow-up in hair toxicology.Results: We found a significant time-by-group interaction on uncertainty-based decision-making (effect size: η2 = .05), although post-hoc tests to disentangle this interaction yielded inconclusive results (p-range = .14-.40; BF10-range = 0.43-1.67). There were no significant time-by-group interactions on response inhibition or delay discounting, with the former likely a null effect (η2-interaction = .003 and .02; BFincl = 0.23 and 0.71). There were no significant differences in cognitive recovery between individuals who maintained abstinence (n = 12) versus relapsed (n = 65) (η2-range = .003-.04), although evidence was inconclusive toward whether findings reflected true null effects (BFincl-range = 0.33-0.75).Conclusion: We did not find evidence that MUD-related cognitive impulsivity deficits improve beyond practice effects over 6 weeks. Findings do not support previous, albeit conflicting, evidence of early recovery of cognitive deficits in MUD.

Assessing the impacts of daily Cannabis versus alcohol and methamphetamines on young Australians in youth AOD treatment.

BACKGROUND: Cannabis is the most widely used illicit substance by Australian young people, including those engaged with youth alcohol and other drug (AOD) systems. While recreational cannabis use in young people may be a developmental activity for some, for others, this usage becomes regular and be associated with poorer long term outcomes. This study reports on the rates of cannabis use and co-existing psychosocial complexity factors in the Youth Needs Census (2013 and 2016) where workers report on all clients in the youth AOD system, a cohort considered highly vulnerable. METHODS: Data was examined for two rounds of data collection for the Youth Needs Census, including 823 youth AOD service engaged young people in 2016 and 1000 AOD service engaged young people in 2013, to identify usage rates, psychosocial outcomes, and changes over time. RESULTS: Daily use of cannabis alone significantly exceeded daily usage rates for methamphetamines, alcohol, and cannabis used alongside other substances. Daily cannabis use was significantly associated with mental health problems, employment problems, education problems, family problems, and housing problems. Daily cannabis use was associated with most psychosocial complexity factors to the same extent as daily methamphetamine use and daily alcohol use, with daily cannabis users only showing lower incidence of the drug-related harm measure. Notably, daily cannabis use also increased from 2013 (47.5%) to 2016 (54.2%). CONCLUSIONS: It is imperative that the number of individuals using cannabis is considered alongside the severity of harm when assessing the social impact of this substance. Within cannabis users engaged with the youth AOD system, who often have high levels of psychosocial complexity, cannabis is used daily by a large proportion of these youths and may play a role in negatively impacting their lives.

Increased demand for amphetamine treatment in rural Australia.

BACKGROUND: A substantial increase in substance treatment episodes for methamphetamine problems suggests characteristics of the treatment population could have changed and that targeted treatment programs are required. To determine who methamphetamine treatment should be designed for this study has two aims. First, to empirically describe changes in amphetamine treatment presentations to a rural NSW drug and alcohol treatment agency over time. Second, to examine how these characteristics may affect the likelihood of being treated for amphetamines compared to other drugs. METHOD: The Australian Alcohol and Other Drug Treatment Services National Minimum Data Set (AODTS-NMDS) containing closed treatment episodes from a single agency from three time periods was used. Characteristics of people receiving amphetamine treatments in these three periods were compared and the effects of these characteristics on the odds of being treated for amphetamine were estimated using a logistic regression model. The characteristics utilised in the analysis include age, sex, Indigenous status, usual accommodation, living arrangement, source of referral and source of income. RESULTS: The proportion of amphetamine treatment episodes doubled from 2006/2007 to 2015/2016 and overtook alcohol as the most commonly treated principal drug of concern. The estimated proportion of amphetamine treatments showed an increment across all ages and for men and women. It was found that younger people, women, people in temporary accommodation or homeless, people who were self-referred and people whose main source of income was not through employment are more likely to be treated for amphetamine use. CONCLUSION: Significant changes over time in the age, sex and Indigenous status of people receiving treatment for amphetamine as the principal drug of concern requires service delivery to match demand from younger people, particularly women; and Indigenous people. The needs and preferences for treatment of younger women who use amphetamine will be important factors in treatment planning service providers who are more used to providing treatment for young men who use cannabis and older men who use alcohol. Further research on women's experiences in treatment and outcomes would be useful for informing treatment practices.

Oxytocin-enhanced motivational interviewing group therapy for methamphetamine use disorder in men who have sex with men: study protocol for a randomized controlled trial.

BACKGROUND: The prevalence of methamphetamine use disorder (MUD) in the United States has risen dramatically in the past four decades and is concentrated in populations such as men who have sex with men (MSM). Despite the public health consequences of MUD, there are no FDA-approved psychopharmacological treatments. Psychosocial treatment alone has been shown to reduce methamphetamine use, but high attrition rates limit treatment efficacy. Promising findings from animal models of MUD using exogenous oxytocin, a social neuropeptide, have set the stage for translational work. Along with unique anti-addiction effects, oxytocin holds a primary role in enhancing social salience and modulating stress. In humans, oxytocin administration, combined with evidence-based psychosocial interventions, may act synergistically to improve addiction treatment outcomes and improve retention rates in current MUD treatment. METHODS/DESIGN: We are conducting a randomized, double-blind, placebo-controlled trial of oxytocin-enhanced motivational interviewing group therapy (MIGT). Oxytocin or placebo 40 IU is administered intranasally in conjunction with six, weekly MIGT sessions. We will recruit 50 MSM, initiating treatment for MUD from specialized community health programs in San Francisco, CA, USA. Individuals will be randomized (1:1) to receive six, weekly sessions of MIGT with or without oxytocin. Our primary outcome is session attendance. Other outcomes of interest include: measures of group cohesion, anxiety, psychophysiology, and stimulant craving and use. DISCUSSION: This will be the first study of oxytocin's effects in humans with MUD. Findings from this novel protocol will attempt to bridge existing animal data with the need for innovative clinical treatments for MUD, inform the growing field of pharmacologically-enhanced psychotherapy, and help to elucidate mechanisms behind oxytocin's potential anti-addiction effects. TRIAL REGISTRATION: ClinicalTrials.gov, ID: NCT02881177 . Registered on 26 August 2016.

Randomized controlled trial of a positive affect intervention for methamphetamine users.

BACKGROUND: Contingency management (CM) is an evidence-based intervention providing rewards in exchange for biomarkers that confirm abstinence from stimulants such as methamphetamine. We tested the efficacy of a positive affect intervention designed to boost the effectiveness of CM with HIV-positive, methamphetamine-using sexual minority men. METHODS: This attention-matched, randomized controlled trial of a positive affect intervention delivered during CM was registered on www.clinicaltrials.gov (NCT01926184). In total, 110 HIV-positive sexual minority men with biologically confirmed, recent methamphetamine use were enrolled. Five individual sessions of a positive affect intervention (n = 55) or an attention-control condition (n = 55) were delivered during three months of CM. Secondary outcomes examined over the 3-month intervention period included: 1) psychological processes relevant to affect regulation (i.e., positive affect, negative affect, and mindfulness); 2) methamphetamine craving; 3) self-reported stimulant use (past 3 months); and 4) cumulative number of urine samples that were non-reactive for stimulants (i.e., methamphetamine and cocaine) during CM. RESULTS: Those randomized to the positive affect intervention reported significant increases in positive affect during individual sessions and increases in mindfulness over the 3-month intervention period. Intervention-related improvements in these psychological processes relevant to affect regulation were paralleled by concurrent decreases in methamphetamine craving and self-reported stimulant use over the 3-month intervention period. CONCLUSIONS: Delivering a positive affect intervention may improve affect regulation as well as reduce methamphetamine craving and stimulant use during CM with HIV-positive, methamphetamine-using sexual minority men.

Influence of physical activity on addiction parameters of rats exposed to amphetamine which were previously supplemented with hydrogenated vegetable fat.

Amphetamine (AMPH) and its derivatives are addictive drugs used to promote and enhance alertness, motivation, willingness, courage and wellbeing. However, their chronic use is related to memory loss, emotional instability, insomnia, psychosis and paranoia. In the last decades, modern society has included processed foods, rich in trans fatty acids (TFA), in their diet, what has been related to several health problems including increased AMPH preference and self-administration. In this scenario, physical activity appears to be useful to attenuate rewarding symptoms related to addictive drugs mainly by affecting brain neuroplasticity and neurotransmission. The current study has been developed to assess the influence of physical activity on addiction parameters of rats exposed to AMPH which were previously supplemented with hydrogenated vegetable fat (HVF), rich in TFA. After six weeks of HVF or soybean oil (SO, control group) supplementation, adult rats were conditioned with d,l-AMPH or vehicle for 14 days. Then, half of each experimental group was submitted to physical activity in treadmill running sessions (60min/day, 5 days/week) for 5 weeks. Animals were re-conditioned with AMPH or vehicle for 3 more days, to observe drug relapse. Locomotor activity and anxiety-like symptoms were observed 24h after the last AMPH reconditioning, and fatty acids composition was quantified in the ventral tegmental area, striatum and prefrontal cortex. All animals showed AMPH preference, but only SO sedentary showed drug relapse. No differences were observed in locomotor activity among groups, while HVF-supplemented group showed decreased exploration per se, and physical activity prevented this. Moreover, AMPH-HVF group showed increased anxiety-like symptoms, which were prevented by physical activity. These results indicate that HVF supplementation modifies AMPH addiction, whereas regular physical activity could be protective against both AMPH and TFA damages.

Beneficial effects of Tai Chi for amphetamine-type stimulant dependence: a pilot study.

BACKGROUND: Tai Chi is a traditional Chinese sport that is classified as a moderate exercise. Recent studies have evaluated the effectiveness of Tai Chi in substance abuse rehabilitation. OBJECTIVES: The aim of this study was to assess the quality of life and physical effects of a Tai Chi intervention on individuals with amphetamine-type stimulant (stimulant) dependence. METHODS: Sixty male subjects with stimulant dependence from a Shanghai Mandatory Detoxification and Rehabilitation Center participated in a 12-week trial. Tai Chi was used as an intervention in the experimental group (n = 30). The control group (n = 29) underwent standard care, which included recreation activity, gesture language exercise, and self-education. Outcome measures included the quality of life for drug addiction (QOL-DA) questionnaire [four scales consisting of physiology (e.g., energy level), psychology (e.g., depression), symptoms (e.g., physical symptoms), society (e.g., interpersonal) and fitness evaluations (assessed by body mass index, body fat, hand-grip, flexibility, balance)]. Repeated measures were used to analyze the changes over time. RESULTS: Test scores of the QOL-DA in the Tai Chi group significantly increased after 12 weeks in the following areas: physiology, 8.71 (p = 0.005), symptoms, 4.34 (p = 0.042), society, 15.79 (p < 0.001), and total score, 10.60 (p = 0.002). A post hoc test further revealed that quality of life improved in the Tai Chi group but not in the standard care group. Physical results showed a significant interaction with balance(F(1,56) = 6.92, p = 0.011); participants in the Tai Chi group improved by 10 s while there was no change in the standard care group. Although there were no significant interactions in the fitness outcomes (i.e., hand-grip and sit-and-reach tests), the within-group factor displayed significant changes in body fat (F(1,56) = 27.79, p < 0.001) in both groups. CONCLUSION: This study demonstrates that Tai Chi is a promising exercise that improves quality of life for individuals with stimulant dependence.

Neurofeedback Training as a New Method in Treatment of Crystal Methamphetamine Dependent Patients: A Preliminary Study.

This study aimed to compare the effectiveness of neurofeedback (NFB) plus pharmacotherapy with pharmacotherapy alone, on addiction severity, mental health, and quality of life in crystal methamphetamine-dependent (CMD) patients. The study included 100 CMD patients undergoing a medical treatment who volunteered for this randomized controlled trial. After being evaluated by a battery of questionnaires that included addiction severity index questionnaire, Symptoms Check List 90 version, and World Health Organization Quality of Life, the participants were randomly assigned to an experimental or a control group. The experimental group received thirty 50-min sessions of NFB in addition to their usual medication over a 2-month period; meanwhile, the control group received only their usual medication. In accordance with this study's pre-test-post-test design, both study groups were evaluated again after completing their respective treatment regimens. Multivariate analysis of covariance showed the experimental group to have lower severity of addiction, better psychological health, and better quality of life in than the control group. The differences between the two groups were statistically significant. These finding suggest that NFB can be used to improve the effectiveness of treatment results in CMD patients.

Epidemiological trends and the advances of treatments of amphetamine-type stimulants (ATS) in China.

BACKGROUND AND OBJECTIVES: Amphetamine-type stimulants (ATS) have quickly spread and been widely abused in many parts of the world, particularly in China. This review focuses on and describes the epidemiological trends and the advances of treatments of ATS in China. METHODS: A descriptive study based on literature identified from searches of the China National Knowledge Infrastructure (1979-2013), PubMed databases, hand-picked references, and online references with emphasis on epidemiology, treatment and traditional Chinese medicine. This review covers some traditional Chinese treatments and their complementary Western approaches. RESULTS AND CONCLUSIONS: The epidemiological trends of ATS in China have led to its being 2.2 times the rate of morphine abuse and second only to marijuana abuse. The treatment programs in China have used traditional herbal approaches as well as acupuncture, often in combination with Western medications such as fluoxetine for depression associated with ATS abuse. Other herbal treatments have reversed the cardiac arrhythmias associated with ATS intoxication, and acupuncture has been used successfully for the protracted depressive and somatic symptoms of ATS withdrawal over a period of 3 months. SCIENTIFIC SIGNIFICANCE: These traditional Chinese treatments may be increasingly available to the world, but will remain a consistent complementary therapy for ATS in China and the Far East, where ATS has become such a prevalent problem.

Methamphetamine use: a comprehensive review of molecular, preclinical and clinical findings.

Methamphetamine (MA) is a highly addictive psychostimulant drug that principally affects the monoamine neurotransmitter systems of the brain and results in feelings of alertness, increased energy and euphoria. The drug is particularly popular with young adults, due to its wide availability, relatively low cost, and long duration of psychoactive effects. Extended use of MA is associated with many health problems that are not limited to the central nervous system, and contribute to increased morbidity and mortality in drug users. Numerous studies, using complementary techniques, have provided evidence that chronic MA use is associated with substantial neurotoxicity and cognitive impairment. These pathological effects of the drug, combined with the addictive properties of MA, contribute to a spectrum of psychosocial issues that include medical and legal problems, at-risk behaviors and high societal costs, such as public health consequences, loss of family support and housing instability. Treatment options include pharmacological, psychological or combination therapies. The present review summarizes the key findings in the literature spanning from molecular through to clinical effects.

Prevalence of malnutrition and nutritional risk factors in patients undergoing alcohol and drug treatment.

OBJECTIVE: Chronic substance abuse is recognized to affect nutritional status and is associated with nutrient deficiencies and malnutrition. This study aimed to identify the prevalence of malnutrition and nutritional risk factors using a spread of measurements in patients undergoing alcohol and drug treatment. METHODS: Sixty-seven patients (48 male, 19 female) admitted to a public hospital detoxification unit participated: 49 were alcohol dependent (73%) and the remaining were opiate, benzodiazepine, and/or amphetamine dependent. Nutritional status was assessed by the Subjective Global Assessment. An appetite questionnaire (Simplified Nutritional Appetite Questionnaire), a diet-quality questionnaire (Australian Recommended Food Score), and blood biochemistry and hematologic tests were also applied. RESULTS: The prevalence of mild/moderate malnutrition was 24% according to the Subjective Global Assessment. Weight and body mass index were associated with nutritional status (P < 0.05). Appetite and diet quality were poor overall, with 88% of all participants requiring advice and guidance. Blood markers showed that 50% of all subjects were deficient in iron or vitamins (low vitamin A levels in 21%, low iron levels in 18%, low-range potassium in 12%, and low vitamin C levels in 8%). CONCLUSION: The prevalence of malnutrition in this patient population is likely to underestimate the prevalence of nutritional risk factors and micronutrient undernutrition. Multiple tools assessing nutritional status, appetite, diet quality, and blood test results have different advantages and can further identify the specific needs and appropriateness of nutritional education in patients during treatment for drug and alcohol use.

Characteristics of treatment provided for amphetamine use in New South Wales, Australia.

The purpose of this study was to examine the types of treatment services provided for amphetamine use, the characteristics of amphetamine treatment clients and the geographic areas most affected by amphetamine treatment provision within New South Wales (NSW), Australia. Data on completed amphetamine treatment episodes were extracted from the NSW Minimum Data Set for Alcohol and Other Drug Treatment Services for the year 2002/03 (n = 4,337). The geographic area of treatment presentations was based on the location of the treatment service, and was categorized as metropolitan, regional or rural. Treatment disproportionately affected regional and rural NSW, and treatment clients often presented with concurrent cannabis and/or alcohol problems. Clients were overwhelmingly injecting drug users with poor socio-demographic characteristics. Counselling was the most common treatment service provided, followed by detoxification and residential rehabilitation. Detoxification was usually provided in an in-patient setting, particularly within metropolitan NSW. Compliance with residential rehabilitation was notably poor. In conclusion, the development of appropriate interventions for amphetamine use needs to consider that the majority of treatment recipients will be based in a regional or rural setting, and treating amphetamine users will often involve treatment of concurrent cannabis and alcohol problems. The nature and appropriateness of treatment services provided for amphetamine use needs to be reviewed in detail, and further research is needed into the nature of problematic amphetamine use and factors affecting treatment demand in regional and rural NSW.

Relevancia para el tratamiento de la sintomatología depresiva de los pacientes adictos / Importance for the treatment of depressive symptomatology in addited patients

Muchos de los pacientes que acuden a los tratamientos por consumo de drogas acusan una serie de problemas solapados, a veces, por la propia adicción y que llegan a condicionar el resultado final de la intervención terapéutica. Para precisar la incidencia de algunos de esos problemas estudiamos una muestra de 210 sujetos adictos sometidos a tratamiento (83 por ciento varones y 17 por ciento mujeres) tratando de interrelacionar diferentes tipos de problemas (legales, laborales, económicos, familiares, psicopatológicos, etc.) con su evolución terapéutica. Una de las variables que con más consistencia parece predecir los resultados del tratamiento es precisamente el nivel de sintomatología depresiva aducido por el propio paciente. Para valorar más la incidencia de esta variable fueron comparados los pacientes con sintomatología depresiva (75 sujetos) con los carentes de esos síntomas (135 sujetos). Los datos indican que los pacientes con sintomatología depresiva tienen un ambiente familiar más problemático y conflictivo, diferenciándose de manera significativa de aquellos otros carentes de dichos síntomas, lo que parece añadir más complicaciones a su recuperación. A juzgar por estos datos, sería conveniente diversificar los tratamientos con intervenciones expresamente dirigidas al abordaje de la sintomatología depresiva y problemática familiar de cara a optimizar los resultados de la intervención (AU)

Many of the patients who undertake treatment for drug consumption reveal a series of overlapping problems, sometimes due to their own addiction. These problems influence the final results of therapeutic supervision. In order to accurately determine the influence of some of these problems, we studied a sample of 210 addicts subjected to treatment (83% males and 17% females), trying to correlate the various types of problems (legal, vocational, economic, psychopathologic as well as family problems, etc.) with their therapeutic evolution. One of the variables which seems most consistently to predict treatment results is precisely the level of depressive symptomatology shown by the patient. To more accurately assess the influence of this variable, we compared 75 subjectpatients, all of them presenting depressive symptomatology, with 135 patients who did not. The data indicated that patients with certain levels of depressive symptomatology came from more problematic and conflictive family environments, a significant difference from those who did not present those symptoms. This seems to complicate their recovery. Judging by the data, it would be advisable to diversify treatment, with procedures that specifically address depressive symptomatology and family environment, with the aim of optimizing treatment results (AU)
