The Norwegian patient experiences with GP questionnaire (PEQ-GP): reliability and construct validity following a national survey.

ABSTRACT: OBJECTIVES:The aim of this study was to test the reliability and validity of a new questionnaire for measuring patient experiences with general practitioners (PEQ-GP) following a national survey. SETTING:Postal survey among patients on any of 500 GPs patient lists in Norway. GPs were stratified by practice size and geographical criteria. PARTICIPANTS:4964 patients who had at least one consultation with their regular GP in the foregoing 12 months were included in the study. The patients were randomly selected after the selection of GPs. 2377 patients (49%) responded to the survey. PRIMARY AND SECONDARY OUTCOME MEASURES:The items were assessed for missing data and ceiling effects. Factor structure was assessed using exploratory factor analyses. Reliability was tested with item-total correlation, Cronbach's alpha and test-retest correlations. Item discriminant validity was tested by correlating items with all scales. Construct validity was assessed through associations of scale scores with health status, the patients' general satisfaction with the services, whether the patient had been incorrectly treated by the GP and whether the patient would recommend the GP to others. RESULTS:Item missing varied from 1.0% to 3.1%, while ceiling effects varied from 16.1% to 45.9%. The factor analyses identified three factors. Reliability statistics for scales based on these three factors, and two theoretically derived scales, showed item-total correlations ranging from 0.63 to 0.85 and Cronbach's alpha values from 0.77 to 0.93. Test-retest correlation for the five scales varied from 0.72 to 0.88. All scales had the expected association with other variables. CONCLUSIONS:The PEQ-GP has good evidence for data quality, internal consistency and construct validity. The PEQ-GP is recommended for use in local, regional and national surveys in Norway, but further studies are needed to assess the instrument's ability to detect differences over time and between different GPs.

Project description:ObjectivesPatient experience questionnaires have been criticised owing to the lack of supporting psychometric evidence. The objective of this study was to describe the development and psychometric evaluation of the Cancer Patient Experiences Questionnaire (CPEQ) in Norway.DesignQuestionnaire development was based on a literature review of existing questionnaires, patient interviews, expert-group consultations, pretesting of questionnaire items and a national survey. Psychometric evaluation included exploratory and confirmatory factor analysis, and tests of internal consistency reliability and test-retest reliability.SettingData were collected using a postal survey of cancer patients attending 54 hospitals in all 4 health regions. The subjects were 14 227 adult cancer patients who had attended an outpatient clinic or who had been discharged from an inpatient ward. Patients with all types of cancer were included. Data quality, internal consistency reliability and construct validity were assessed.ResultsOf the 13 846 patients who received the CPEQ, 7212 (52%) responded. Exploratory factor analysis identified six scales of outpatient experiences relating to nurse contact, doctor contact, information, organisation, patient safety and contact with next of kin, and seven scales of inpatient experiences, with the addition of hospital standard to the aforementioned scales. All but two of the scales met the criterion of 0.70 for Cronbach's ? testing, and test-retest correlations ranged from 0.57 to 0.85. Confirmatory factor analysis supported the interpretation of six and seven scales for outpatients and inpatients, respectively. Statistically significant associations based on explicit hypotheses provided evidence for the construct validity of the scales. One additional scale measuring the hospital level was identified (?=0.85).ConclusionsThe CPEQ is a self-report instrument that includes the most important aspects of patient experiences with cancer care at hospitals. The instrument was tested following a national survey in Norway; good evidence is provided herein for the internal consistency reliability, test-retest reliability and construct validity.

Project description:Study objectivesto evaluate the reliability and validity of the Brief Insomnia Questionnaire (BIQ), a fully structured questionnaire developed to diagnose insomnia according to hierarchy-free Diagnostic and Statistical Manual, Fourth Edition, Text Revision (DSM-IV-TR), International Classification of Diseases-10 (ICD-10), and research diagnostic criteria/International Classification of Sleep Disorders-2 (RDC/ICSD-2) general criteria without organic exclusions in the America Insomnia Survey (AIS).Designprobability subsamples of AIS respondents, oversampling BIQ positives, completed short-term test-retest interviews (n = 59) or clinical reappraisal interviews (n = 203) to assess BIQ reliability and validity.Settingthe AIS is a large (n = 10,094) epidemiologic survey of the prevalence and correlates of insomnia.Participantsadult subscribers to a national managed healthcare plan.InterventionNoneMeasurements and resultsBIQ test-retest correlations were 0.47-0.94 for nature of the sleep problems (initiation, maintenance, nonrestorative sleep [NRS]), 0.72-0.95 for problem frequency, 0.66-0.88 for daytime impairment/distress, and 0.62 for duration of sleep. Good individual-level concordance was found between BIQ diagnoses and diagnoses based on expert interviews for meeting hierarchy-free inclusion criteria for diagnoses in any of the diagnostic systems, with area under the receiver operating characteristic curve (AUC, a measure of classification accuracy insensitive to disorder prevalence) of 0.86 for dichotomous classifications. The AUC increased to 0.94 when symptom-level data were added to generate continuous predicted-probability of diagnosis measures. The AUC was lower for dichotomous classifications based on RDC/ICSD-2 (0.68) and ICD-10 (0.70) than for DSM-IV-TR (0.83) criteria but increased consistently when symptom-level data were added to generate continuous predicted-probability measures of RDC/ICSD-2, ICD-10, and DSM-IV-TR diagnoses (0.92-0.95).Conclusionsthese results show that the BIQ generates accurate estimates of the prevalence and correlates of hierarchy-free insomnia in the America Insomnia Survey.
