Abstract
Heavy substance use (SU) and substance use disorders (SUD) have complex etiologies and often severe consequences. Certain personality traits have been associated with an increased risk for SU(D), but far less is known about personality changes related to SU(D). This review aims to synthesize the existing literature on this research question. A systematic literature search was conducted from November 2022 to February 2023 in PubMed, EbscoHost, and Web of Science. Peer-reviewed original papers on SU(D)-related personality changes were included. Of 55 included studies, 38 were observational population-based studies and 17 were intervention studies. Overall, personality and SU measures, samples, study designs, and statistical approaches were highly heterogenous. In observational studies, higher SU was most consistently related to increases in impulsivity-related traits and (less so) neuroticism, while interventions in the context of SU(D) were mostly associated with increases in conscientiousness and self-efficacy and lasting decreases in neuroticism. Findings for traits related to extraversion, openness, conscientiousness, and agreeableness were mixed and depended on SU measure and age. Studies on bidirectional associations suggest that personality and SU(D) both influence each other over time. Due to their strong association with SU(D), impulsivity-related traits may be important target points for interventions. Future work may investigate the mechanisms underlying personality changes related to SU(D), distinguishing substance-specific effects from general SU(D)-related processes like withdrawal, craving, and loss of control. Furthermore, more research is needed to examine whether SU(D)-related personality changes vary by developmental stage and clinical features (e.g. initial use, onset, remission, and relapse).

Improving psychosocial health and employment outcomes for individuals receiving methadone treatment: a realist synthesis of what makes interventions work. BMC Psychol 2014; 2:26. [PMID: 25566385 PMCID: PMC4269989 DOI: 10.1186/s40359-014-0026-3] [Citation(s) in RCA: 7] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/28/2014] [Accepted: 08/06/2014] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND For over 50 years, methadone has been prescribed to opioid-dependent individuals as a pharmacological approach for alleviating the symptoms of opioid withdrawal. However, individuals prescribed methadone sometimes require additional interventions (e.g., counseling) to further improve their health. This study undertook a realist synthesis of evaluations of interventions aimed at improving the psychosocial and employment outcomes of individuals on methadone treatment, to determine what interventions work (or not) and why. METHODS The realist synthesis method was utilized because it uncovers the processes (or mechanisms) that lead to particular outcomes, and the contexts within which this occurs. A comprehensive search process resulted in 31 articles for review. Data were extracted from the articles, and placed in four templates to assist with analysis. Data analysis was an iterative process and involved comparing and contrasting data within and across each template, and cross checking with original articles to determine key patterns in the data. RESULTS For individuals on methadone, engagement with an intervention appears to be important for improved psychosocial and/or employment outcomes. The engagement process involves attendance at interventions as well as an investment in what is offered. Three intervention contexts (often in some combination) support the engagement process: a) client-centered contexts (or those where clients' psychosocial and/or employment needs/issues/skills are recognized and/or addressed); b) contexts which address clients' socio-economic conditions and needs; and, c) contexts where there are positive client-counselor and/or peer relationships. There is some evidence that sometimes ongoing engagement is necessary to maintain positive outcomes. There is also some evidence that complete abstinence from drugs (e.g., cocaine, heroin) is not necessary for engagement. CONCLUSIONS It is important to consider how the contexts of interventions might elicit and/or support clients' engagement. Further research is needed to explore how an individual's background (e.g., involvement with different interventions over an extended period) may influence engagement. Long-term engagement may be necessary to sustain some positive outcomes although how long is unclear and requires further research. Engagement can occur without complete abstinence from such drugs as cocaine or heroin, but additional research is required as engagement may be influenced by the extent and type of drug use.

Abstract
BACKGROUND Maintenance treatments are effective in retaining patients in treatment and suppressing heroin use. Questions remain regarding the efficacy of additional psychosocial services. OBJECTIVES To evaluate the effectiveness of any psychosocial plus any agonist maintenance treatment versus standard agonist treatment for opiate dependence SEARCH STRATEGY We searched the Cochrane Drugs and Alcohol Group trials register (June 2011), Cochrane Central Register of Controlled Trials (CENTRAL) (Issue 6, 2011), PUBMED (1996 to 2011); EMBASE (January 1980 to 2011); CINAHL (January 2003 to 2011); PsycINFO (1985 to 2003) and reference list of articles. SELECTION CRITERIA Randomised controlled trials and controlled clinical trial comparing any psychosocial plus any agonist with any agonist alone for opiate dependence. DATA COLLECTION AND ANALYSIS Two authors independently assessed trial quality quality and extracted data. MAIN RESULTS 35 studies, 4319 participants, were included. These studies considered thirteen different psychosocial interventions. Comparing any psychosocial plus any maintenance pharmacological treatment to standard maintenance treatment, results do not show benefit for retention in treatment, 27 studies, 3124 participants, RR 1.03 (95% CI 0.98 to 1.07), abstinence by opiate during the treatment, 8 studies, 1002 participants, RR 1.12 (95% CI 0.92 to 1.37), compliance, three studies, MD 0.43 (95% CI -0.05 to 0.92), psychiatric symptoms, 3 studies, MD 0.02 (-0.28 to 0.31), depression, 3 studies, MD -1.70 (95% CI -3.91 to 0.51) and results at the end of follow up as number of participants still in treatment, 3 studies, 250 participants, RR 0.90 (95% CI 0.77 to 1.07) and participants abstinent by opioid, 3 studies, 181 participants, RR 1.15 (95% CI 0.98 to 1.36). Comparing the different psychosocial approaches, results are never statistically significant for all the comparisons and outcomes. AUTHORS' CONCLUSIONS For the considered outcomes, it seems that adding any psychosocial support to standard maintenance treatments do not add additional benefits. Data do not show differences also for contingency approaches, contrary to all expectations. Duration of the studies was too short to analyse relevant outcomes such as mortality. It should be noted that the control intervention used in the studies included in the review on maintenance treatments, is a program that routinely offers counselling sessions in addition to methadone; thus the review, actually, did not evaluate the question of whether any ancillary psychosocial intervention is needed when methadone maintenance is provided, but the narrower question of whether a specific more structured intervention provides any additional benefit to a standard psychosocial support. These interventions probably can be measured and evaluated by employing diverse criteria for evaluating treatment outcomes, aimed to rigorously assess changes in emotional, interpersonal, vocational and physical health areas of life functioning.

Abstract
BACKGROUND Different pharmacological approaches aimed at opioid detoxification are effective. Nevertheless a majority of patients relapse to heroin use, and relapses are a substantial problem in the rehabilitation of heroin users. Some studies have suggested that the sorts of symptoms which are most distressing to addicts during detoxification are psychological rather than physiological symptoms associated with the withdrawal syndrome. OBJECTIVES To evaluate the effectiveness of any psychosocial plus any pharmacological interventions versus any pharmacological alone for opioid detoxification, in helping patients to complete the treatment, reduce the use of substances and improve health and social status. SEARCH STRATEGY We searched the Cochrane Drugs and Alcohol Group trials register (June 2011), Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library Issue 6, 2011), PUBMED (1996 to June 2011); EMBASE (January 1980 to June 2011); CINAHL (January 2003 to June 2008); PsycINFO (1985 to April 2003) and reference list of articles. SELECTION CRITERIA Randomised controlled trials and controlled clinical trial which focus on any psychosocial associated with any pharmacological intervention aimed at opioid detoxification. People less than 18 years of age and pregnant women were excluded. DATA COLLECTION AND ANALYSIS Two authors independently assessed trials quality and extracted data. MAIN RESULTS Eleven studies, 1592 participants, fulfilled the criteria of inclusion and were included in the review. The studies considered five different psychosocial interventions and two pharmacological treatments (methadone and buprenorphine). Compared to any pharmacological treatment alone, the association of any psychosocial with any pharmacological was shown to significantly reduce dropouts RR 0.71 (95% CI 0.59 to 0.85), use of opiate during the treatment, RR 0.82 (95% CI 0.71 to 0.93), at follow up RR 0.66 (95% IC 0.53 to 0.82) and clinical absences during the treatment RR 0.48 (95%CI 0.38 to 0.59). Moreover, with the evidence currently available, there are no data supporting a single psychosocial approach. AUTHORS' CONCLUSIONS Psychosocial treatments offered in addition to pharmacological detoxification treatments are effective in terms of completion of treatment, use of opiate, participants abstinent at follow-up and clinical attendance. The evidence produced by this review is limited due to the small number of participants included in the studies, the heterogeneity of the assessment or the lack of detailed outcome information that prevented the possibility of cumulative analysis for several outcomes. Nevertheless it seems desirable to develop adjunct psychosocial approaches that might make detoxification more effective.

Limitations to this review are imposed by the heterogeneity of the assessment of outcomes.

Abstract
There has been a growing interest in the substance abuse treatment field in bringing together the treatment and research communities. While dialogues about logistical and philosophical issues are important, the development of shared core concepts could potentially be quite helpful in facilitating communication and creating common treatment and research goals. It is the contention of this paper that all psychosocial and, potentially, pharmacological treatments ideally address, in part or in full, three aspects of the self--the capacity to regulate emotional and behavioral expression, the ability to engage in future-oriented, goal-directed behavior, and the development of nonaddict and/or recovery-oriented identities. Examples from the research and treatment literature are provided.

Abstract
BACKGROUND Methadone maintenance at proper doses is effective in retaining patients in treatment and suppressing heroin use. Questions remain regarding the efficacy of the psychosocial services that are offered by most maintenance programs. OBJECTIVES To evaluate the effectiveness of any psychosocial plus any agonist maintenance treatment versus any agonist treatment alone in retaining patients in treatment, reducing the use of substances and improving health and social status. SEARCH STRATEGY We searched the Cochrane Central Register of Trials (CENTRAL) issue 3, 2003; MEDLINE 1966-2003; EMBASE 1980-2003; PsycINFO 1985-2003; relevant web sites; scan of reference list of relevant articles. There were no language or publication restrictions. SELECTION CRITERIA RCTs which focus on any psychosocial plus any agonist compared to any agonist maintenance intervention for opiate dependence. People aged less than 18 and pregnant women were excluded. Psychosocial in combination with antagonist maintenance treatment are excluded too. DATA COLLECTION AND ANALYSIS The trials were independently assessed for inclusion and methodological quality by the reviewers. Data were extracted independently and double checked. MAIN RESULTS The searching process resulted in the identification of 77 different studies: 12 studies met the inclusion criteria. These studies considered 8 different psychosocial interventions and 1 pharmacological treatment: Methadone Maintenance (MMT). The results show additional benefit in adding any psychosocial treatment to standard methadone maintenance treatment in relation to the use of heroin during the treatment RR 0.69 (95% CI 0.53-0.91); no statistically significant additional benefit was shown in terms of retention in treatment RR 0.94 (95% CI 0.85-1.02); and results at follow-up RR 0.90 (95% CI 0.76-1.07). REVIEWERS' CONCLUSIONS The present evidence suggests that adding any psychosocial support to Standard MMT significantly improves the non-use of heroin during treatment. Retention in treatment and results at follow-up are also improved, although this findings did not achieve statistical significance. Insufficient evidence is available on other possible relevant outcomes such as Psychiatric symptoms/psychological distress, Quality of life. Limitations to this review are imposed by the heterogeneity of the trials both in the interventions and the assessment of outcomes. Results of studies were sometimes in disagreement and because of lack of detailed information no meta analysis could be performed to analyse the results related to the outcomes more often reported as positive results in the single studies. Duration of the studies was also too short to analyse other relevant outcomes such as mortality. In order to study the possible added value of any psychosocial treatment over an already effective treatment such as standard MMT, only big multi-site studies could be considered which define experimental interventions and outcomes in the most standardized way as possible.

Abstract
Many drug abusers do not seek help in formal treatment settings, and little is known about their resistance to treatment. In this study, we offered a treatment referral assessment to a sample of 283 drug users. Only 58 subjects (or 20.5% of the sample) accepted this offer. We explored differences between those who accepted the treatment referral assessment and those who declined the opportunity. Logistic regression identified predictors of acceptance related to higher levels of severity in drug use and higher scores on a motivation and readiness scale. Among those who declined the assessment, 43.1 % denied drug use, 37.3% thought their drug use was not a problem, and 16.4% expressed no interest in treatment. Further analysis showed that scores on motivation and readiness were positively related to a higher level of severity In employment problems, family problems, and drug use, and to having a history of prior treatment.
