Development and Validation of a Self-reported Questionnaire for Measuring Internet Search Dependence.

ABSTRACT: Internet search has become the most common way that people deal with issues and problems in everyday life. The wide use of Internet search has largely changed the way people search for and store information. There is a growing interest in the impact of Internet search on users' affect, cognition, and behavior. Thus, it is essential to develop a tool to measure the changes in psychological characteristics as a result of long-term use of Internet search. The aim of this study is to develop a Questionnaire on Internet Search Dependence (QISD) and test its reliability and validity. We first proposed a preliminary structure and items of the QISD based on literature review, supplemental investigations, and interviews. And then, we assessed the psychometric properties and explored the factor structure of the initial version via exploratory factor analysis (EFA). The EFA results indicated that four dimensions of the QISD were very reliable, i.e., habitual use of Internet search, withdrawal reaction, Internet search trust, and external storage under Internet search. Finally, we tested the factor solution obtained from EFA through confirmatory factor analysis (CFA). The results of CFA confirmed that the four dimensions model fits the data well. In all, this study suggests that the 12-item QISD is of high reliability and validity and can serve as a preliminary tool to measure the features of Internet search dependence.

Project description:BackgroundImproving the coordination of cancer care is a priority area for service improvement. However, quality improvement initiatives are hindered by the lack of accurate and reliable measures of this aspect of cancer care. This study was conducted to develop a questionnaire to measures patients' experience of cancer care coordination and to assess the psychometric properties of this instrument.MethodsQuestionnaire items were developed on the basis of literature review and qualitative research involving focus groups and interviews with cancer patients, carers and clinicians. The draft instrument was completed 686 patients who had been recently treated for a newly diagnosed cancer, including patients from metropolitan, regional and rural areas of New South Wales, Australia. To assess test-retest reliability, 119 patients completed the questionnaire twice. Unreliable items those with limited variability or high levels of missing data were eliminated. Exploratory factor analysis was conducted to define the underlying factor structure of the remaining items and subscales were constructed. Correlations between these and global measures of the experience of care coordination and the quality of care were assessed.ResultsOf 40 items included in the draft questionnaire, 20 were eliminated due to poor test-retest reliability (n = 4), limited response distributions (n = 8), failure to load onto a factor (n = 7) or detrimental effect on the internal consistency of the scale (n = 1). The remaining 20 items loaded onto two factors named 'Communication' and 'Navigation', which explained 91% of the common variance. Internal consistency was with high for the instrument (Cronbach's alpha 0.88) and each subscale (Cronbach's alpha 0.87 and 0.73 respectively). There was no apparent 'floor' or 'ceiling' effect for the total score or the Communication subscale, but evidence of a ceiling effect for the Navigation subscale with 21% of respondents achieving the highest possible score. There were moderate positive associations between the total score and global measures of care coordination (r = 0.57) and quality of care (r = 0.53).ConclusionsThe instrument developed in this study demonstrated consistency and robust psychometric properties. It may provide a useful tool to measure patients' experience of cancer care coordination in future surveys and intervention studies.
