Client Satisfaction Questionnaire
Also known as: CSQ, CSQ-8, Client Satisfaction Scale, Consumer Satisfaction Questionnaire
The Client Satisfaction Questionnaire (CSQ) is a brief, standardized self-report measure of how satisfied clients are with the human services they receive, most commonly used in its eight-item form, the CSQ-8. Developed by Daniel Larsen, C. Clifford Attkisson, and colleagues in 1979, it produces a single satisfaction score that programs use as a consumer-perspective indicator of service quality, complementing outcome measures by capturing whether clients found the service helpful, of good quality, and worth recommending.
Key highlights
- Brief and easy to administer, enabling routine, large-scale collection of the client perspective.
- Standardized and validated with strong internal consistency, so scores are comparable across clients and settings.
- Captures the consumer's experience of service quality, complementing clinical outcome measures.
- Widely used and translated, supporting benchmarking against other programs and populations.

When to use it
Use the Client Satisfaction Questionnaire when you want a brief, validated, comparable measure of client satisfaction for program evaluation, quality improvement, or accountability reporting in human services. It is well suited to capturing the consumer perspective efficiently and at scale. It is less appropriate as a measure of clinical outcome (satisfaction is not effectiveness), when ceiling effects from generally high satisfaction limit discrimination, or when responses may be biased by clients' fear that candid feedback could affect their care, which calls for anonymity and careful interpretation.
Strengths & limitations
- Brief and easy to administer, enabling routine, large-scale collection of the client perspective.
- Standardized and validated with strong internal consistency, so scores are comparable across clients and settings.
- Captures the consumer's experience of service quality, complementing clinical outcome measures.
- Widely used and translated, supporting benchmarking against other programs and populations.
- Satisfaction is not the same as effectiveness; high satisfaction can coexist with poor outcomes and vice versa.
- Satisfaction ratings are typically high and skewed, producing ceiling effects that limit discrimination.
- Responses can be biased by acquiescence, gratitude, or fear that candor will affect future care.
- A global satisfaction score reveals little about which specific aspects of service drove it.

Frequently asked
Does high client satisfaction mean the program works?
Not necessarily. Satisfaction measures how clients experienced the service — its quality, helpfulness, and whether they would recommend it — which is valuable in its own right but distinct from effectiveness. Clients can be very satisfied with a service that produced little change, or dissatisfied with one that helped them. For this reason the CSQ is used alongside outcome measures, not as a substitute; treating satisfaction as proof of effectiveness is a common and serious misinterpretation.
Why are satisfaction scores usually so high?
Client satisfaction ratings tend to cluster near the top of the scale because of acquiescence, gratitude for help received, and reluctance to criticize providers — sometimes amplified by fear that negative feedback could affect future care. This produces ceiling effects that compress the range and make it hard to discriminate among programs. Anonymity, careful question framing, and interpreting changes relative to the program's own baseline rather than absolute levels help manage this.
How long is the CSQ?
The most widely used version, the CSQ-8, has eight items rated on a four-point scale, giving a total from 8 to 32. Longer (18-item) and shorter (4-item) versions also exist. The eight-item form is popular because it is quick to complete, has strong internal consistency, and yields a single comparable satisfaction score, making it practical for routine administration across large numbers of clients in program evaluation.
