title: The Client Satisfaction Questionnaire: psychometric properties in a Dutch addict population.
abstract: OBJECTIVE
  The aim of this study is to investigate psychometric properties of the Client Satisfaction Questionnaire (CSQ-8) in a Dutch substance abuse population.
  
  
  METHODS
  The CSQ-8 and the Mental Health Thermometer (the standard Dutch satisfaction instrument) were sent to 927 patients of a Dutch substance abuse treatment centre. (response rate 28.3%; n = 262). Data were compared on several variables (i.e., age, gender, ethnicity, treatment type). For a subgroup of responders (n = 84), data were compared with pre-treatment problem severity and treatment need (the European Addiction Severity Index).
  
  
  RESULTS
  Both internal consistency and concurrent validity were found to be high. Only treatment type had significant effects on CSQ-8 satisfaction scores. Scores were negatively skewed.
  
  
  CONCLUSIONS
  The CSQ-8 is as suitable an instrument to be used in addict populations, as it is in other populations.
