Treatment Satisfaction Questionnaire for Medication (TSQM)
Also known as: TSQM
The Treatment Satisfaction Questionnaire for Medication (TSQM) is a 14-item generic measure developed by Atkinson and colleagues in 2004 to assess patient satisfaction with medication across diverse therapeutic areas and disease conditions. It measures four key dimensions—Effectiveness, Side Effects, Convenience, and Global Satisfaction—with standardized 0–100 scoring, making it suitable for cross-disease comparison and health economic evaluation. The TSQM has become a standard outcome in pharmaceutical research, clinical trials, and real-world medication effectiveness studies.
Key highlights
- Multidimensional assessment: Captures effectiveness, tolerability, and convenience—the key drivers of patient satisfaction—rather than a single global measure.
- Standardized 0–100 scoring: Facilitates comparison across diseases, countries, and time periods; suitable for meta-analysis and health economic evaluation.
- Validated across diverse conditions: Originally validated in a panel of 800+ chronically ill individuals covering diabetes, hypertension, asthma, arthritis, depression, and others.
- Clinically actionable: Domain scores directly inform treatment adjustments (e.g., 'side effects are the barrier; consider switching agents' or 'convenience is the problem; simplify regimen').
- Predicts adherence and persistence: Higher TSQM scores correlate with better medication adherence, persistence, and clinical outcomes.

When to use it
The TSQM is appropriate for any patient on medication and is particularly valuable in situations where patient-centered outcomes drive clinical decisions: medication selection when multiple options exist, early identification of dissatisfaction before non-adherence, health economic analyses, and clinical trials assessing patient preference and satisfaction as secondary outcomes. It is widely used in pharmaceutical industry research, quality improvement initiatives, and real-world effectiveness studies. The generic structure allows cross-disease comparison, making it suitable for health systems research and policy decisions.
Strengths & limitations
- Multidimensional assessment: Captures effectiveness, tolerability, and convenience—the key drivers of patient satisfaction—rather than a single global measure.
- Standardized 0–100 scoring: Facilitates comparison across diseases, countries, and time periods; suitable for meta-analysis and health economic evaluation.
- Validated across diverse conditions: Originally validated in a panel of 800+ chronically ill individuals covering diabetes, hypertension, asthma, arthritis, depression, and others.
- Clinically actionable: Domain scores directly inform treatment adjustments (e.g., 'side effects are the barrier; consider switching agents' or 'convenience is the problem; simplify regimen').
- Predicts adherence and persistence: Higher TSQM scores correlate with better medication adherence, persistence, and clinical outcomes.
- Generic structure: While useful for cross-disease comparison, may lack sensitivity to disease-specific concerns (e.g., pregnancy risk in antiepileptic medication, sexual dysfunction in antipsychotics).
- Perception-based, not objective: Reflects patient perception of effectiveness, not verified clinical response; a patient may perceive high effectiveness due to placebo or expectancy effects.
- Snapshot in time: A single assessment may not capture temporal changes in satisfaction as side effects emerge or efficacy becomes apparent.
- Does not assess adherence directly: Measures satisfaction, which correlates with but does not determine adherence; patient may be highly satisfied but still non-adherent due to practical barriers.
- Requires baseline medication use: Cannot assess satisfaction with a medication the patient has never taken; limited for medication selection before initiation.

Frequently asked
How do I interpret a situation where Effectiveness is high (85) but Side Effects are low (35)?
The medication is perceived as clinically effective but is causing bothersome side effects. Options include: (1) dose reduction to improve tolerability while maintaining benefit, (2) add-on medications to manage specific side effects, (3) switching to an alternative agent, or (4) detailed discussion of side effect severity and whether the benefit justifies tolerating them. Explore which side effects are most problematic and whether they are likely to improve with time or require intervention.
Can I use TSQM to compare satisfaction between two medications in the same patient?
Yes. Administer TSQM for each medication separately (retrospectively if the patient has switched, or prospectively if on sequential regimens). Comparing domain scores can identify which medication better aligns with patient priorities (e.g., one medication may be more convenient but less effective, while another is effective but inconvenient). This comparison supports shared decision-making.
What if a patient has high satisfaction (80+) but low adherence?
This paradox suggests that satisfaction is not the primary barrier. Investigate practical obstacles: inability to fill prescriptions, cost barriers, complexity of instructions, forgetfulness, or social factors. TSQM measures satisfaction, not adherence capacity; other barriers require targeted problem-solving (reminders, simplified regimens, cost assistance, education).
Is TSQM appropriate for newly prescribed medications?
TSQM is less reliable for medications taken for very short durations (<1–2 weeks) because patients have limited experience to evaluate effectiveness and side effect patterns. Ideally, assess after at least 2–4 weeks of consistent use. For acute medications, use with caution and specify the timeframe: 'Rate your satisfaction over the past 2 weeks of use.'
