Objective—To assess validity and reliability for a visual analogue scale (VAS) used by owners to measure chronic pain in their osteoarthritic dogs. Sample—68, 61, and 34 owners who completed a questionnaire. Procedures—Owners answered questionnaires at 5 time points. Criterion validity of the VAS was evaluated for all dogs in the intended-to-treat population by correlating scores for the VAS with scores for the validated Helsinki Chronic Pain Index (HCPI) and a relative quality-of-life scale. Intraclass correlation was used to assess repeatability of the pain VAS at 2 baseline evaluations. To determine sensitivity to change and face validity of the VAS, 2 blinded, randomized control groups (17 dogs receiving carprofen and 17 receiving a placebo) were analyzed over time. Results—Significant correlations existed between the VAS score and the quality-of-life scale and HCPI scores. Intraclass coefficient (r = 0.72; 95% confidence interval, 0.57 to 0.82) for the VAS indicated good repeatability. In the carprofen and placebo groups, there was poor correlation between the 2 pain evaluation methods (VAS and HCPI items) at the baseline evaluation, but the correlation improved in the carprofen group over time. No correlation was detected for the placebo group over time. Conclusions and Clinical Relevance—Although valid and reliable, the pain VAS was a poor tool for untrained owners because of poor face validity (ie, owners could not recognize their dogs' behavior as signs of pain). Only after owners had seen pain diminish and then return (after starting and discontinuing NSAID use) did the VAS have face validity.

Pediculosis capitis is an ectoparasitic disease that lives on the human scalp and caused by Pediculus humanus capitis. This incident is categorized as a neglected case, but the impact is quite significant. The incident can give a negative impact, including physical, psychological, social and school perceptions or learning impairment. This study aimed to determine the relationship between the incidence of pediculosis capitis with the quality of life of female students of Madrasah Ulumul Quran Sigli. This research is an observational analytic study with a cross-sectional approach. The samples were collected by the total sampling method. The results obtained from 155 respondents who met the inclusion criteria found that 124 respondents (80%) had pediculosis capitis and 31 respondents (20%) with no pediculosis capitis. Statistical analysis using the chi square test obtained a p value of 0.000 (0.05). The conclusion was found that there was a relationship between the incidence of pediculosis capitis and the quality of life of female students of Madrasah Ulumul Quran Sigli.
