Summary
The Client Satisfaction Questionnaire (CSQ-8) demonstrates high reliability and validity for assessing patient satisfaction in Dutch substance abuse treatment. This validated instrument is suitable for use with addiction populations.
Area of Science:
- Psychometric evaluation
- Addiction treatment research
- Mental health assessment
Background:
- Patient satisfaction is a key outcome in addiction treatment.
- The Client Satisfaction Questionnaire (CSQ-8) is widely used but requires validation in specific populations.
- Assessing satisfaction in Dutch substance abuse populations is crucial for treatment improvement.
Purpose of the Study:
- To evaluate the psychometric properties of the CSQ-8.
- To determine the suitability of the CSQ-8 for Dutch substance abuse patients.
- To compare CSQ-8 performance with a standard Dutch satisfaction instrument.
Main Methods:
- The CSQ-8 and Mental Health Thermometer were administered to 927 patients.
- A response rate of 28.3% (n=262) was achieved.
- Data were analyzed for internal consistency, concurrent validity, and demographic/treatment variable effects.
Main Results:
- The CSQ-8 exhibited high internal consistency and concurrent validity.
- Treatment type significantly influenced CSQ-8 satisfaction scores.
- Satisfaction scores were negatively skewed, indicating generally high satisfaction.
Conclusions:
- The CSQ-8 is a psychometrically sound instrument for assessing satisfaction in Dutch substance abuse populations.
- The CSQ-8 is as suitable for addiction populations as it is for other patient groups.
- Findings support the use of CSQ-8 in clinical and research settings for substance abuse treatment.
