Assessment of the quality and variability of health information on chronic pain websites using the DISCERN instrument

<p>Abstract</p> <p>Background</p> <p>The Internet is used increasingly by providers as a tool for disseminating pain-related health information and by patients as a resource about health conditions and treatment options. However, health information on the Internet remains unregulated and varies in quality, accuracy and readability. The objective of this study was to determine the quality of pain websites, and explain variability in quality and readability between pain websites.</p> <p>Methods</p> <p>Five key terms (pain, chronic pain, back pain, arthritis, and fibromyalgia) were entered into the Google, Yahoo and MSN search engines. Websites were assessed using the DISCERN instrument as a quality index. Grade level readability ratings were assessed using the Flesch-Kincaid Readability Algorithm. Univariate (using alpha = 0.20) and multivariable regression (using alpha = 0.05) analyses were used to explain the variability in DISCERN scores and grade level readability using potential for commercial gain, health related seals of approval, language(s) and multimedia features as independent variables.</p> <p>Results</p> <p>A total of 300 websites were assessed, 21 excluded in accordance with the exclusion criteria and 110 duplicate websites, leaving 161 unique sites. About 6.8% (11/161 websites) of the websites offered patients' commercial products for their pain condition, 36.0% (58/161 websites) had a health related seal of approval, 75.8% (122/161 websites) presented information in English only and 40.4% (65/161 websites) offered an interactive multimedia experience. In assessing the quality of the unique websites, of a maximum score of 80, the overall average DISCERN Score was 55.9 (13.6) and readability (grade level) of 10.9 (3.9). The multivariable regressions demonstrated that website seals of approval (<it>P </it>= 0.015) and potential for commercial gain (<it>P </it>= 0.189) were contributing factors to higher DISCERN scores, while seals of approval (<it>P </it>= 0.168) and interactive multimedia (<it>P </it>= 0.244) contributed to lower grade level readability, as indicated by estimates of the beta coefficients.</p> <p>Conclusion</p> <p>The overall quality of pain websites is moderate, with some shortcomings. Websites that scored high using the DISCERN questionnaire contained health related seals of approval and provided commercial solutions for pain related conditions while those with low readability levels offered interactive multimedia options and have been endorsed by health seals.</p

Psychometric validation of PHQ-9 and GAD-7 in Filipino migrant domestic workers in Macao

There are 500,000 female Filipino domestic workers worldwide. However, there are no validated instruments to assess common mental disorders in this population. The Patient Health Questionnaire (PHQ–9) and Generalized Anxiety Disorder (GAD–7) are brief measures that could be effective screeners for depression and anxiety in domestic workers. This study aims to establish reliability and validity of the Filipino versions of the PHQ–9 and GAD–7. In Study 1, 131 domestic workers completed the PHQ–9, GAD–7, and other questionnaires with a test–retest interval of 10 days. Convergent validity was examined using measures of posttraumatic stress disorder, direct exposure to traumatic events, and rumination. Discriminant validity was assessed using measures of discrimination, pain, social support, and indirect exposure to traumatic events. In Study 2, criterion validity was established with another sample of domestic workers (N = 100) using clinician-administered Mini International Neuropsychiatric Interviews. Receiver operating characteristic (ROC) curve analysis was performed to evaluate diagnostic efficiency. Results showed acceptable and high internal consistency for PHQ–9 and GAD–7, respectively. Both had acceptable test–retest reliability. Convergent and discriminant validity were also established. ROC curve results demonstrated that optimal cut scores for PHQ–9 and GAD–7 are 6 and 7, respectively. The Filipino versions of PHQ–9 and GAD–7 are reliable and valid for use among Filipino domestic workers

Predicting aggression in adults with intellectual disability: A pilot study of the predictive efficacy of the Current Risk of Violence and the Short Dynamic Risk Scale

Background: Structured assessments have been shown to assist professionals to evaluate the risk of aggression in secure services for general offender populations and more recently among adults with intellectual disabilities. There is a need to develop intellectual disability sensitive measures for predicting risk of aggression in community samples, especially tools with a focus on dynamic variables. / Methods: The study prospectively followed 28 participants for up to 2 months to test whether the Current Risk of Violence (CuRV) and Short Dynamic Risk Scale (SDRS) were able to predict verbal and physical aggression in a community sample of adults with intellectual disability. / Results: CuRV and SDRS ratings significantly predicted verbal and physical aggression over a 2‐month period. / Conclusions: The current study supports the use of the CuRV with adults with intellectual disability living in community settings. The CuRV and SDRS are worthy of future development and evaluation in independent investigations
