Assessing self-determined motivation for addiction treatment: validity of the Treatment Entry Questionnaire

'I went for rehab many times and it never worked, but the harm reduction process has given me renewed hope'. Perceptions on the effectiveness of harm reduction and community-based opioid substitution therapy

ISSUE ADDRESSED

The accessibility of opioid substitution therapy (OST), one of the recommended treatments for opioid dependence, remains low. This study sought to explore the perceived effectiveness of OST from the perspectives of peer outreach workers and OST clients in a community-based harm reduction programme.

METHODS

The research was done within the Community-Oriented Substance Use Programme (COSUP) in Tshwane, South Africa. Fifteen peer educators (13 males and 2 females) took part in two focus group discussions. Thereafter, there were semi-structured interviews in which 15 OST clients (11 males and 4 females) participated. A convenience cross-sectional study was used. Interviews were audio-recorded. Using thematic analysis, themes were examined to evaluate how OST and the harm reduction approach were perceived to contribute to the improved health status of people with opioid dependence.

RESULTS

Peer outreach workers and COSUP clients significantly endorsed OST as an effective treatment for opioid dependence. Participants perceived greater effectiveness of OST compared to abstinence-centred inpatient rehabilitation programmes. However, there were sentiments that more community education on OST was needed to motivate people with opioid dependence to access services and to address misconceptions about OST.

CONCLUSIONS

There is a lack of multi-level and multi-sectoral engagement of various stakeholders in opioid dependence services, needed to accelerate utilisation of OST services. SO WHAT?: The research unpacks the need for an integrated approach to service use optimisation, and the need to evaluate the role that increased awareness and community education on harm reduction strategies can play in enhancing the utilisation of OST services.

A six-session group-based pilot intervention for alcohol and other drug use in hospitalised mentally ill young offenders

OBJECTIVE

This study aims to evaluate a group-based intervention for alcohol and other drug (AOD) use offered to incarcerated youth hospitalised with mental illness.

METHODS

A six-session group-based intervention for AOD use was offered to young offenders with mental illness, hospitalised in the Adolescent Unit of the Forensic Hospital, Sydney, between June 2015 and May 2017. Pre- and post-intervention measures were collected using the Brief Psychiatric Rating Scale (BPRS), Treatment Entry Questionnaire, Drug-Related Locus of Control (DRLOC) and Drug-Taking Confidence Questionnaire, short version.

RESULTS

Pre- and post-intervention measures were compared utilising paired t-tests. Following the intervention, there was a significant reduction in the severity of psychiatric symptoms rated using the BPRS and a significant difference in DRLOC measures, reflecting increased internal locus of control.

CONCLUSIONS

Improved internal drivers for reducing AOD use and improvement in symptoms of mental illness suggest similar interventions may be beneficial and may not impact recovery even during episodes of acute illness.

Psychometric evaluation of the treatment entry questionnaire to assess extrinsic motivation for inpatient addiction treatment

INTRODUCTION

Valid multi-faceted measurement of motivation for substance use disorder (SUD) treatment is needed to help inform treatment approaches and predict outcomes. This study examined evidence of validity for the Treatment Entry Questionnaire (TEQ-9).

METHODS

Data represented individuals entering inpatient SUD treatment (n = 1455). We used confirmatory factor analysis (CFA) to assess the three-factor structure of the TEQ-9 [identified (i.e., values/personally chooses treatment), introjected (i.e., internally controlled by guilt/shame) and external motivations (i.e., external pressure/demands)], and examined measurement invariance across gender, age, and ethno-racial identity. Correlation with readiness and confidence assessed convergent validity, while correlations with substance use problem severity and previous substance use treatment assessed meaningful group differences.

RESULTS

A three-factor structure was confirmed with all items loading significantly onto their respective factors (ps < 0.001). Each subscale demonstrated high internal consistency (Identified α = 0.90; Introjected α = 0.79; External α = 0.85). Each subscale demonstrated measurement invariance up to the scalar level across all sub-groups. Readiness, confidence, and substance use problem severity correlated as expected across various substances with the identified (rs = 0.098 - 0.262, ps < 0.05), and external (rs = -0.096 - -0.178, ps < 0.05) subscales. Additionally, the mean Identified subscale score was significantly higher among those who previously engaged in SUD treatment (p < 0.001). Findings for the Introjected subscale were more ambiguous.

CONCLUSIONS

Findings provide evidence for factorial validity, measurement invariance, convergent validity and group differences of the TEQ-9 in a large clinically mixed inpatient SUD treatment population, providing further support of its clinical and research utility.

App-based maintenance treatment for alcohol use disorder after acute inpatient treatment: Study protocol for a multicentre randomized controlled trial

BACKGROUND

Alcohol use disorder, a prevalent and disabling mental health problem, is often characterized by a chronic disease course. While effective inpatient and aftercare treatment options exist, the transferal of treatment success into everyday life is challenging and many patients remain without further assistance. App-based interventions with human guidance have great potential to support individuals after inpatient treatment, yet evidence on their efficacy remains scarce.

OBJECTIVES

To develop an app-based intervention with human guidance and evaluate its usability, efficacy, and cost-effectiveness.

METHODS

Individuals with alcohol use disorder (DSM-5), aged 18 or higher, without history of schizophrenia, undergoing inpatient alcohol use disorder treatment (N = 356) were recruited in eight medical centres in Bavaria, Germany, between December 2019 and August 2021. Participants were randomized in a 1:1 ratio to either receive access to treatment as usual plus an app-based intervention with human guidance (intervention group) or access to treatment as usual plus app-based intervention after the active study phase (waitlist control/TAU group). Telephone-based assessments are conducted by diagnostic interviewers three and six weeks as well as three and six months after randomization. The primary outcome is the relapse risk during the six months after randomization assessed via the Timeline Follow-Back Interview. Secondary outcomes include intervention usage, uptake of aftercare treatments, AUD-related psychopathology, general psychopathology, and quality of life.

DISCUSSION

This study will provide further insights into the use of app-based interventions with human guidance as maintenance treatment in individuals with AUD. If shown to be efficacious, the intervention may improve AUD treatment by assisting individuals in maintaining inpatient treatment success after returning into their home setting. Due to the ubiquitous use of smartphones, the intervention has the potential to become part of routine AUD care in Germany and countries with similar healthcare systems.

Approaches for Implementing App-Based Digital Treatments for Drug Use Disorders Into Primary Care: A Qualitative, User-Centered Design Study of Patient Perspectives

Background

Digital interventions, such as websites and smartphone apps, can be effective in treating drug use disorders (DUDs). However, their implementation in primary care is hindered, in part, by a lack of knowledge on how patients might like these treatments delivered to them.

Objective

This study aims to increase the understanding of how patients with DUDs prefer to receive app-based treatments to inform the implementation of these treatments in primary care.

Methods

The methods of user-centered design were combined with qualitative research methods to inform the design of workflows for offering app-based treatments in primary care. Adult patients (n=14) with past-year cannabis, stimulant, or opioid use disorder from 5 primary care clinics of Kaiser Permanente Washington in the Seattle area participated in this study. Semistructured interviews were recorded, transcribed, and analyzed using qualitative template analysis. The coding scheme included deductive codes based on interview topics, which primarily focused on workflow design. Inductive codes emerged from the data.

Results

Participants wanted to learn about apps during visits where drug use was discussed and felt that app-related conversations should be incorporated into the existing care whenever possible, as opposed to creating new health care visits to facilitate the use of the app. Nearly all participants preferred receiving clinician support for using apps over using them without support. They desired a trusting, supportive relationship with a clinician who could guide them as they used the app. Participants wanted follow-up support via phone calls or secure messaging because these modes of communication were perceived as a convenient and low burden (eg, no copays or appointment travel).

Conclusions

A user-centered implementation of treatment apps for DUDs in primary care will require health systems to design workflows that account for patients’ needs for structure, support in and outside of visits, and desire for convenience.

Protocol for Outcome Evaluation of Ayahuasca-Assisted Addiction Treatment: The Case of Takiwasi Center

The present study describes the protocol for the Ayahuasca Treatment Outcome Project (ATOP) with a special focus on the evaluation of addiction treatment services provided through Takiwasi Center, the first ATOP study site. The goal of the project is to assess treatment outcomes and understand the therapeutic mechanisms of an Ayahuasca-assisted, integrative treatment model for addiction rehabilitation in the Peruvian Amazon. The proposed intervention protocol highlights the significance of treatment setting in the design, delivery, and efficacy of an addiction rehabilitation program that involves the potent psychedelic tea known as Ayahuasca. After describing the context of the study, we put forth details about our mixed-methods approach to data collection and analysis, with which we seek to gain an understanding of why, how, and for whom this specific ayahuasca-assisted treatment program is effective across a range of outcomes. The ATOP protocol employs qualitative research methods as a means to determine which aspects of the setting are meaningful to clients and practitioners, and how this may correlate with outcome measures. This paper delineates the core principles, methods, and measures of the overall ATOP umbrella, then discusses the role of ATOP in the context of the literature on long-term residential programs. To conclude, we discuss the strengths and limitations of the protocol and the intended future of the project.

Scoping Review on the Concept of Patient Motivation and Practical Tools to Assess it

Background:

In this scoping review, the concept of patients' motivation and the tools that have been designed to measure this concept in clinical settings are presented.

Materials and Methods:

Arksey and O'Malley's framework was used in conducting the current scoping review. Google Scholar, PubMed, Scopus, and Web of Science databases were searched for relevant English articles published between January 1995 and January 2020 using the keywords motivation and tool, and their synonyms. Out of 2820 articles, 34 articles were chosen and were entered into the final analysis. Definitions of patients' motivation were determined using Kyngäs et al., content analysis method.

Results:

The findings showed that new tools had been developed in 38% of the studies and other studies had revised or translated existing questionnaires. Moreover, 62% of the tools were used to measure patient motivation in mental disorders. Most of the studies did not clearly define the concept of patient motivation in the clinical environment. The findings of content analysis outlined the 3 categories of motivation determinant factors, decisions, and behaviors that determine overall levels of motivations and its consequences.

Conclusions:

Motivation is a dynamic concept and is a result of internal and external motives that lead to decisions and behaviors. There are limited tools for measuring motivation in clinical settings. This addresses the need to design specific tools in various diseases, especially chronic diseases. By the concept defined in this study, it is possible to design a short tool with general application that can be used in all diseases.

Supporting Intrapersonal Development in Substance Use Disorder Programs: A Conceptual Framework for Client Assessment

PURPOSE

Improvements to intrapersonal development of clients involved with substance use disorder treatment programs has widely been recognized as contributing to the intended goal of reducing substance misuse behaviors. This study sought to identify a broad framework of primary outcomes related to the intrapersonal development of clients in treatment for substance misuse.

METHOD

Using qualitative research methods, individual interviews were conducted with program participants (n = 41) at three treatment programs to identify the ways in which respondents experienced intrapersonal development through participation in treatment.

RESULTS

The findings support the development of a conceptual model that captures the importance and manifestation of achieving improvements in the following outcomes: self-awareness, coping ability, self-worth, outlook, and self-determination.

DISCUSSION

The findings provide a conceptual framework for client assessment that captures a broad range of the important intrapersonal development factors utilized as indicators for client development and recovery that should be measured in tandem during assessment.

The role of motivation in predicting antiretroviral therapy adherence in China

Patient motivation is important in managing medication regimens such as antiretroviral treatment for HIV/AIDS. We tested whether self-determination theory could predict adherence behavior among 115 HIV-positive patients in the China Adherence through Technology Study, a randomized controlled trial of an intervention using text reminders and supportive counseling to increase adherence. Being in the treatment group had a significant effect on improving adherence; however, we did not find evidence that self-determination theory predicts adherence in this population of HIV-positive patients. Autonomous motivation was strongly associated with perceived competence; among low adherers, external regulation was negatively correlated with adherence.

Different Perspectives of Clinicians and Patients with Severe Mental Illness on Motivation for Treatment

The present study assessed motivation for engaging in treatment as rated by clinicians (n = 57) and patients with severe mental illness (SMI, n = 294) using measures based on three different motivation theories. Questionnaires were derived from self-determination theory, the transtheoretical model and the integral model of treatment motivation. It was investigated to which extent clinicians of patients with SMI were able to estimate their patient's perspective on motivation for engaging in treatment, to which extent they agreed on the patient's motivation and which factors were associated with estimation and agreement on treatment motivation. It was found that clinicians were poorly to moderately capable of estimating their patient's type of motivation and readiness for change. Further, agreement on the level of motivation between patients and clinicians was moderate. These findings were consistent across diagnostic groups (psychotic and personality disorders). A higher quality therapeutic relationship was generally associated with higher clinician-rated motivation. The patient's ethnicity and socially desirable responding were factors that differentiated between scales of different motivation theories. It is concluded that patients with SMI and their clinicians have different perceptions on the patient's motivation for engaging in psychiatric treatment, regardless of the theoretical framework that is used to measure motivation. The findings imply that a negotiated approach is needed where both perceptions of clinicians and patients on motivation for treatment are considered to ensure effective mental health interventions.

KEY PRACTITIONER MESSAGE

Clinicians show poor to moderate capability in estimating how patients perceive their motivation for engaging in treatment, especially so when the patient's motives revolve around feelings of shame and guilt. Clinicians generally give higher motivation ratings for patients where they experience a higher quality therapeutic relationships with, whereas-depending on the scale that is used to measure motivation-they give lower ratings to patients who respond in socially desirable ways and to ethnic minority patients. As patients with SMI and their clinicians have different perceptions on the patient's motivation for engaging in psychiatric treatment (regardless of the theoretical framework that is used to assess motivation), this implies that a negotiated approach is needed where both perceptions of clinicians and patients on motivation for treatment are considered to ensure effective mental health interventions.

The Survey of Treatment Entry Pressures (STEP): identifying client's reasons for entering substance abuse treatment

OBJECTIVE

Systematically identifying reasons that clients enter substance abuse treatment may allow clinicians to immediately focus on issues of greatest relevance to the individual and enhance treatment engagement. We developed the Survey of Treatment Entry Pressures (STEP) to identify the specific factors that precipitated an individual's treatment entry. The instrument contains 121 items from 6 psychosocial domains (i.e., family, financial, social, medical, psychiatric, legal). The current study examined the STEP's psychometric properties.

METHOD

A total of 761 participants from various treatment settings and modalities completed the STEP prior to treatment admission and 4-7 days later. Analyses were performed to examine the instrument's psychometric properties including item response rates, test-retest reliability, internal consistency, and factor structure.

RESULTS

The items displayed adequate test-retest reliability and internal consistency within each psychosocial domain. Generally, results from exploratory and confirmatory factor analyses support a 2-factor structure reflecting type of reinforcement schedule.

CONCLUSION

The study provides preliminary support for the psychometric properties of the STEP. The STEP may provide a reliable way for clinicians to characterize and capitalize on a client's treatment motivation early on which may serve to improve treatment retention and therapeutic outcomes.

Measures of motivation for psychiatric treatment based on self-determination theory: psychometric properties in Dutch psychiatric outpatients

Self-determination theory is potentially useful for understanding reasons why individuals with mental illness do or do not engage in psychiatric treatment. The current study examined the psychometric properties of three questionnaires based on self-determination theory-The Treatment Entry Questionnaire (TEQ), Health Care Climate Questionnaire (HCCQ), and the Short Motivation Feedback List (SMFL)-in a sample of 348 Dutch adult outpatients with primary diagnoses of mood, anxiety, psychotic, and personality disorders. Structural equation modeling showed that the empirical factor structures of the TEQ and SMFL were adequately represented by a model with three intercorrelated factors. These were interpreted as identified, introjected, and external motivation. The reliabilities of the Dutch TEQ, HCCQ, and SMFL were found to be acceptable but can be improved on; congeneric estimates ranged from 0.66 to 0.94 depending on the measure and patient subsample. Preliminary support for the construct validities of the questionnaires was found in the form of theoretically expected associations with other scales, including therapist-rated motivation and treatment engagement and with legally mandated treatment. Additionally, the study provides insights into the relations between measures of motivation based on self-determination theory, the transtheoretical model and the integral model of treatment motivation in psychiatric outpatients with severe mental illness.

Does Mandated Treatment Benefit Youth? A Prospective Investigation of Adolescent Justice System Involvement, Treatment Motivation, and Substance Use Outcomes

BACKGROUND

The majority of adolescents treated for substance use disorder (SUD) in the United States are now referred by the criminal justice system. Little is known, however, regarding how justice-system involvement relates to adolescent community treatment outcomes. Controversy exists, also, over the extent to which justice system involvement reflects a lack of intrinsic motivation for treatment. This study examined the relation between justice system referral and reported reason for treatment entry and tested the extent to which each predicted treatment response and outcome.

METHOD

Adolescent outpatients (N = 127; M age = 16.7, 24% female) with varying levels of justice-system involvement (i.e., no justice system involvement [No-JSI; n = 63], justice-system involved [JSI; n = 40], justice system involved-mandated [JSI-M; n = 24]) and motivation levels (i.e., self-motivated [n = 40], externally-motivated [n = 87]) were compared at treatment intake. Multilevel mixed models tested these groups' effects on percent days abstinent (PDA) and odds of heavy drinking (HD) over 12 months.

RESULTS

JSI-M were less likely to be self-motivated compared to No-JSI or JSI (p = 0.009). JSI-M had higher PDA overall, but with significant declines over time, relative to no-JSI. Self-motivated patients did not differ from externally-motivated patients on PDA or HD.

CONCLUSIONS

Mandated adolescent outpatients were substantially less likely to report self-motivated treatment entry. Despite the notion that self-motivated treatment entry would be likely to produce better outcomes, a judicial mandate appears to predict an initially stronger treatment response, although this diminishes over time. Ongoing monitoring and/or treatment may be necessary to help maintain treatment gains for justice system-involved adolescents.

Rasch model of the GAIN substance problem scale among Canadian adults seeking residential and outpatient addiction treatment

BACKGROUND

The GAIN Substance Problem Scale (SPS) measures alcohol and drug problem severity within a DSM-IV-TR framework. This study builds on prior psychometric evaluation of the SPS by using Rasch analysis to assess scale unidimensionality, item severity, and differential item functioning (DIF).

METHODS

Participants were attending residential or outpatient treatment in Alberta and Ontario, Canada, respectively (n=372). Rasch analyses modeled a latent problem severity continuum using SPS scores at treatment admission and 6-week follow-up. We examined DIF by gender, treatment modality (outpatient vs. residential), and assessment timing (baseline vs. follow-up).

RESULTS

Model fit was good overall, supporting unidimensionality and a single underlying continuum of substance problem severity. Relative to person severity, however, the range of item severities was narrow. Items were too severe for many clients to endorse, particularly at follow-up. Overall, the rank order of item severities was stable across gender, treatment modality, and time point. Although traditional Rasch criteria indicated a number of statistically significant and substantive DIF estimates across modality and time points, effect size indices did not suggest a net effect on total scale scores.

CONCLUSIONS

The analysis broadly supports use of the SPS as an additive measure of global substance severity in men and women and both residential and outpatient settings. Although DIF was not a major concern, there was evidence of item redundancy and suboptimal matching between items and persons. Findings highlight potential opportunities for further improving this scale in future research and clinical applications of the GAIN.
