Patient Satisfaction with Complementary and Alternative Medicine Scale
Also known as: PSCS, PSCS-CAM
The PSCS is a patient-report instrument measuring satisfaction with complementary and alternative medicine services, including acupuncture, herbal medicine, massage, and other modalities. Developed by Margolis and colleagues in 1998, it captures dimensions of satisfaction specific to CAM practice—practitioner communication, efficacy expectations, cost concerns, and interpersonal warmth.

When to use it
The PSCS is appropriate for patients receiving CAM services to evaluate satisfaction with their care experience. Use it for routine satisfaction monitoring in CAM clinics or integrative medicine practices, comparative assessment of different CAM practitioners or modalities, evaluation of practice improvements or quality interventions, and research examining relationships between patient satisfaction and adherence, outcomes, or word-of-mouth referrals.
Strengths & limitations
- Operationalizes dimensions of satisfaction specific to CAM—including practitioner warmth, holistic approach, and patient empowerment—not captured by generic health satisfaction scales.
- Brief, easy to administer and score; suitable for routine clinical use and large surveys.
- Captures patient expectations and perceptions of value-for-money, relevant to decision-making about CAM investment.
- Provides actionable feedback for CAM practitioners and clinics to improve service quality and patient retention.
- Recall bias: post-visit or retrospective satisfaction ratings may be influenced by recent symptoms or life events unrelated to CAM quality.
- Response bias: patients who are dissatisfied may be less likely to complete surveys, leading to systematically higher satisfaction estimates.
- Modality variation: items may be more relevant to some CAM modalities (e.g., acupuncture) than others (e.g., herbal supplements); may require adaptation by setting.
- Lacks clinical outcome measurement: high satisfaction does not establish that CAM improved the patient's health or functional status; requires supplementary outcome data.
Frequently asked
Should I use PSCS only for acupuncture, or is it applicable to other CAM modalities?
Originally developed for acupuncture and Chinese medicine, but core satisfaction dimensions (practitioner warmth, communication, perceived effectiveness, cost-value) apply to most CAM modalities. Some items may require wording adjustments for specific modalities (e.g., massage therapy, herbal medicine); verify relevance before use.
Can high PSCS scores predict whether a patient will continue CAM treatment?
Satisfaction is a strong predictor of adherence and continuation in most healthcare settings, including CAM. Patients with high satisfaction scores are more likely to continue treatment, return for follow-up, and recommend to others. However, cost, accessibility, and symptom improvement also influence continuation.
What if a patient reports high satisfaction but reports no symptom improvement?
This is not unusual and reflects different satisfaction dimensions. The patient may value the practitioner's interpersonal approach, explanations, or holistic perspective independent of symptom change. Separate outcome measurement is needed to assess clinical efficacy; PSCS measures experience quality.
How should I interpret mid-range PSCS scores?
Mid-range scores (3–3.5 on 1–5 scale) indicate room for improvement. Examine subscale scores to identify specific domains: if practitioner warmth is high but cost-effectiveness is low, pricing or transparent value discussion may help. Use qualitative feedback (open-ended comments) to understand specific concerns.
