Treatment Motivation Questionnaire (TMQ)
Treatment Motivation Questionnaire · Also known as: TMQ
The TMQ is a self-report instrument designed to measure motivation for substance abuse treatment and predict treatment engagement and outcomes. Developed by Simpson and colleagues in the context of the Drug Outcome Research Study (DORS), the TMQ assesses both intrinsic motivation (desire to address problems, commitment to change) and perceived barriers to treatment engagement. The TMQ is useful in addiction treatment settings to identify individuals with high versus low treatment motivation and to tailor motivational interventions accordingly.

When to use it
The TMQ is appropriate for use at addiction treatment intake to assess baseline motivation and identify individuals who may benefit from motivational interviewing or engagement enhancement strategies before or early in treatment. It is useful in residential, intensive outpatient, and outpatient programs. The TMQ is less suitable as a population-level screening tool; use it in individuals already identified as substance users entering treatment.
Strengths & limitations
- Directly measures treatment motivation and engagement constructs that predict treatment outcomes
- Subscale structure enables identification of specific motivational dimensions (problem recognition, treatment confidence) for targeted intervention
- Brief administration time with straightforward scoring and interpretation
- Strong empirical links to treatment completion and outcome in addiction populations
- Guides case formulation and motivational interviewing focus areas
- Depends on self-report and may be subject to impression management or inaccuracy in early treatment stages
- Motivation is dynamic; baseline TMQ scores may not reflect motivation changes that occur as treatment progresses
- Not all TMQ versions are equally validated; instrument versions vary across studies, limiting comparability
- Motivation predicts outcomes but is not deterministic; individuals with lower baseline motivation can achieve good outcomes with effective treatment
Frequently asked
If my TMQ score is low, does that mean I won't succeed in treatment?
Low baseline motivation predicts lower treatment engagement and outcome risk, but does not guarantee treatment failure. Many individuals with low motivation at intake improve substantially with effective motivational interviewing, treatment engagement, and early success experiences. Motivation is changeable.
What does a low 'Treatment Confidence' subscale mean?
A low Treatment Confidence score indicates you doubt whether treatment can help you. This is common in people who have tried treatment before without success. Discussing your past experiences and building confidence through treatment structure and early wins is important.
Can TMQ scores change during treatment?
Yes. Motivation typically increases as individuals engage in treatment, achieve early successes, and develop therapeutic alliance with their treatment provider. Reassessing TMQ periodically can track motivation changes and inform treatment adjustments.
How does TMQ relate to the Readiness to Change Questionnaire?
TMQ measures overall motivation for treatment (desire to change, belief in treatment effectiveness). RCQ measures stage of readiness (precontemplation, contemplation, action). Both are useful; they measure related but distinct constructs. High TMQ with precontemplation stage may indicate internal conflict.
Should treatment be denied to people with low motivation?
No. Low motivation is itself an indication for motivational intervention, not grounds for exclusion. Motivational interviewing and engagement enhancement are evidence-based strategies for building motivation in reluctant or ambivalent individuals.
What if I have high TMQ but still struggle in treatment?
High motivation is necessary but not sufficient for treatment success. Other factors matter: psychiatric comorbidity, social support, coping skills, life stability. If you are struggling despite high motivation, discuss with your treatment team about additional support or services.
