Examining the Relationship of Personality Functioning and Treatment Completion in Substance Misuse Treatment

Background:

Treatment retention is a major factor contributing to favourable outcome in the treatment of substance misuse, but the literature remains very limited. Despite evidence of the association of personality with drug use experimentation and relapse, surprisingly little is known about its role in the treatment process. Clients’ personality functioning as measured by malleable and context sensitive characteristic adaptations in treatment are of concern.

Aims:

This study examines whether, and to what extent, personality functioning contributes to or hinders treatment completion. This paper examined the extent to which service users’ characteristic adaptations may be potential determinants of treatment completion.

Methodology:

A longitudinal multi-site design was utilised, examining the therapy process in a naturalistic setting in five inpatient treatment units. The study examined whether service users’ characteristic adaptations (SIPP-118) predict completion, while controlling psychosocial, motivational and treatment engagement indicators involving n = 340 participants from 5 inpatient centres. Multivariate regression analyses were applied to examine the predictive role of characteristic adaptations on treatment completion.

Results:

Findings indicated that certain dysfunctional characteristic adaptations emerged as strong predictors of treatment completion. Dysfunctional levels on Self-control and Social concordance were significant predictors of drop out from treatment. Individuals with low capacity to tolerate, use and control one’s own emotions and impulses were almost three times more likely to drop-out compared to those without [OR] = 2.73, Wald = 6.09, P = .014, 95% CI [1.2, 6.0]. Individuals with dysfunctional levels on the ability to value someone’s identity, withhold aggressive impulses towards others and work together with others were 2.21 more times more likely to complete treatment [OR] = 2.21, Wald = 4.12, P = .042, 95% CI [1.0, 4.7]. The analysis at the facet level provided additional insight. Individuals with higher adaptive levels on Effortful Control were 46% more times likely to complete treatment than the group [OR] = 4.67, Wald = 10.231, P = .001, 95% CI [1.81, 12.04], 47% more likely on Aggression regulation [OR] = 4.76, Wald = 16.68, P < .001, 95% CI [2.1, 10.3], and 26% more likely on Stable self-image [OR] = 2.62, Wald = 6.75, P < .009, 95% CI [0.9, 3.0].

Conclusions:

These findings extend our knowledge of the predictive role of characteristic adaptations in treatment completion and highlight the clinical utility of capturing these individual differences early on. Delineating the role of characteristic adaptations in treatment may provide the basis for enhancing treatment effectiveness through individualized interventions that are scientifically driven and may open new avenues for the scientific enquiry of personality and treatment.

Medication-Assisted Opioid Treatment Prescribers in Federally Qualified Health Centers: Capacity Lags in Rural Areas

PURPOSE

This study explores correlates of on-site availability of substance use disorder treatment services in federally qualified health centers, including buprenorphine treatment that is critical to addressing the opioid epidemic.

METHODS

We employed descriptive and multivariable analyses with weighted 2010 Assessment of Behavioral Health Services survey data and the 2010 Uniform Data System.

FINDINGS

In 2010, 47.6% of health centers provided on-site substance use disorder treatment, 12.3% provided buprenorphine treatment for opioids, and 38.8% were interested in expanding buprenorphine availability. Urban health centers, those in the West, and health centers with electronic health records had higher odds of offering on-site substance use disorder treatment. Compared with on-site mental health treatment, substance use disorder treatment was available in fewer clinic sites within each organization. Health centers in rural areas had lower odds of providing on-site buprenorphine treatment (OR = 0.49, 95% CI: 0.26-0.94), and those in the South had lower odds of providing on-site buprenorphine treatment compared with health centers in other regions. Rural health centers had lower odds of expressing interest in expanding the availability of buprenorphine treatment (OR = 0.58, 95% CI: 0.35-0.97).

CONCLUSIONS

Improving access to substance use disorder treatment in primary care is a critical part of the strategy to combat the opioid use disorder epidemic. These findings highlight the important role of health centers as portals of access to substance use disorder treatment services in underserved communities. Recent investments to expand treatment capacity in health centers will expand the availability of substance use disorder services, but urban/rural and regional disparities should be monitored.

Addiction treatment outcomes, process and change: Texas Institute of Behavioral Research at Texas Christian University

For more than 40 years the Texas Institute of Behavioral Research (IBR) has given special attention to assessment and evaluation of drug user populations, addiction treatment services and various cognitive and behavioral interventions. Emphasis has been on studies in real-world settings and the use of multivariate methodologies to address evaluation issues within the context of longitudinal natural designs. Historically, its program of addiction treatment research may be divided into three sequential epochs-the first era dealt mainly with client assessment and its role in treatment outcome and evaluation (1969-89), the second focused upon modeling the treatment process and the importance of conceptual frameworks (1989-2009) in explaining the relationships among treatment environment, client attributes, treatment process and outcome, and the third (and current) era has expanded into studying tactical deployment of innovations and implementation. Recent projects focus upon adapting and implementing innovations for improving early engagement in adolescent residential treatment settings and drug-dependent criminal justice populations. Related issues include the spread of human immunodeficiency virus/acquired immune deficiency syndrome and other infectious diseases, organizational and systems functioning, treatment costs and process related to implementation of evidence-based practices.
