Children’s Perception Scale of Head Lice Infestation (CPS-HLI): Design and Psychometrics
Background: Pediculosis is a common ectoparasitic infestation that involves especially the skin of children worldwide. Studying the children’s perception of the disease’s risk factors, the effectiveness of personal preventive measures, and its implications for their health could be a major leap forward in health promotion activities. Objectives: This study aimed to develop and evaluate the psychometric properties of the Children’s Perception Scale of Head Lice Infestation (CPS-HLI) and its initial feasibility assessment for use on Iranian and possibly other elementary school children. Methods: The scale’s items were retained based on an extensive literature search and classified into the underlying constructs of the Extended Health Belief Model (EHBM). An expert panel endorsed the qualitative content and face validity of the preliminary draft, and 47 items remained for quantitative validity testing on a sample of 362 elementary school students in the city of Paveh, West of Iran. Explanatory and confirmatory factor analyses (EFA and CFA) were employed to test the content and structural validity of the constructed instrument. Cronbach's alpha and intra-class correlation coefficients were calculated to assess the internal consistency and reliability of the scale. Results: The values of Lawshe's content validity index (0.90) and content validity ratio (0.77), the subscales’ Cronbach's alpha (0.59), and intra-class correlation (0.72) coefficients confirmed plausible internal consistency of the scale. The values of root mean square error of approximation (RMSEA) (< 0.08 with χ2 < 0.05), Tucker-Lewis Index (TLI), and Comparative Fit Index (CFI) > 0.9 approved the applied statistical model’s goodness of fit.

期刊介绍:
Archives Of Pediatric Infectious Disease is a clinical journal which is informative to all practitioners like pediatric infectious disease specialists and internists. This authoritative clinical journal was founded by Professor Abdollah Karimi in 2012. The Journal context is devoted to the particular compilation of the latest worldwide and interdisciplinary approach and findings including original manuscripts, meta-analyses and reviews, health economic papers, debates and consensus statements of clinical relevance to pediatric disease field, especially infectious diseases. In addition, consensus evidential reports not only highlight the new observations, original research and results accompanied by innovative treatments and all the other relevant topics but also include highlighting disease mechanisms or important clinical observations and letters on articles published in the journal.
