Background: Development and evaluation of the PEQ-CAMHS Outpatients, a parent completed questionnaire to measure experiences of outpatient child and adolescent mental health services (CAMHS) in Norway.
Methods: Literature review, parent interviews, pre-testing and a national survey of 17,080 parents of children who received care at one of the 86 outpatient CAMHS in Norway in 2006. Telephone interviews were conducted with a random sample of non-respondents. Levels of missing data, factor structure, internal consistency and construct validity were assessed.
Results: 7,906 (46.0%) parents or primary caregivers responded to the questionnaire. Low levels of missing data suggest that the PEQ-CAMHS is acceptable. The questionnaire includes three scales supported by the results of factor analysis: relationship with health personnel (8 items), information and participation (4 items), and outcome (3 items). Item-total correlations were all above 0.6 and Cronbach's alpha correlations ranged from 0.88-0.94. The results of comparisons of scale scores with several variables relating to global satisfaction, outcome, cooperation, information, involvement and waiting time support the construct validity of the instrument.
Conclusions: The PEQ-CAMHS Outpatients questionnaire includes important aspects of outpatient CAMHS from the perspective of the parent. It has evidence for data quality, internal consistency and validity and is recommended in surveys of parent experiences of these services. Future research should assess test-retest reliability and further tests of construct validity that include clinical data are recommended.
