RESUMO
The rates of colorectal cancer (CRC) screening in the U.S. remain below national targets, so many people at risk are not being screened. The objective of this qualitative research project was to assess patient and provider knowledge and preferences about CRC screening modalities and specifically the use of the fecal immunochemical test (FIT) as a first line screening choice. Nine focus groups were conducted with a medically underserved patient population and qualitative interviews were administered to their medical providers. Thematic analysis was used to synthesize key findings. Both providers and patients thought that the FIT would be a good option for CRC screening both as an individual choice and for an overall program approach. The test is less expensive and therefore more readily available for patients compared to colonoscopy. Overall, there was consensus that the FIT offers a reasonably priced, simple approach to CRC screening which has broad appeal to both providers and patients. Concerns identified by patients and providers included the possibility of false positives with the FIT which could be caused by test contamination or failing to perform the test properly. Patients also described feelings of disgust toward performing the FIT and difficulties in following the instructions. Study findings indicate provider and patient support for using the FIT for CRC screening at both the individual and system-wide levels of implementation. While barriers to the use of the FIT were listed, benefits of using the FIT were perceived as positive motivators to engage previously unscreened and uninsured or under-insured individuals in CRC screening.

This study was undertaken to define the number of missing values permissible to render valid total scores for each Movement Disorder Society Unified Parkinson's Disease Rating Scale (MDS-UPDRS) part. To handle missing values, imputation strategies serve as guidelines to reject an incomplete rating or create a surrogate score. We tested a rigorous, scale-specific, data-based approach to handling missing values for the MDS-UPDRS. From two large MDS-UPDRS datasets, we sequentially deleted item scores, either consistently (same items) or randomly (different items) across all subjects. Lin's Concordance Correlation Coefficient (CCC) compared scores calculated without missing values with prorated scores based on sequentially increasing missing values. The maximal number of missing values retaining a CCC greater than 0.95 determined the threshold for rendering a valid prorated score. A second confirmatory sample was selected from the MDS-UPDRS international translation program. To provide valid part scores applicable across all Hoehn and Yahr (H&Y) stages when the same items are consistently missing, one missing item from Part I, one from Part II, three from Part III, but none from Part IV can be allowed. To provide valid part scores applicable across all H&Y stages when random item entries are missing, one missing item from Part I, two from Part II, seven from Part III, but none from Part IV can be allowed. All cutoff values were confirmed in the validation sample. These analyses are useful for constructing valid surrogate part scores for MDS-UPDRS when missing items fall within the identified threshold and give scientific justification for rejecting partially completed ratings that fall below the threshold.

In 2010, the New England Region-National Network of Libraries of Medicine at University of Massachusetts Medical School received funding to improve information access for public health departments in 6 New England states and Colorado. Public health departments were provided with desktop digital access to licensed e-resources available through special pricing. In January through mid-April 2012, we evaluated the effectiveness of providing access to and training for using e-resources to public health department staff to motivate usage in practice. We found that additional strategies are needed to accomplish this.

Background: Patient and public involvement and engagement (PPIE) in the design of trials is important, as participant experience critically impacts delivery. The Edmond J Safra Accelerating Clinical Trials in PD (EJS ACT-PD) initiative is a UK consortium designing a platform trial for disease modifying therapies in PD. Objective: The integration of PPIE in all aspects of trial design and its evaluation throughout the project. Methods: PwP and care partners were recruited to a PPIE working group (WG) via UK Parkinson's charities, investigator patient groups and participants of a Delphi study on trial design. They are supported by charity representatives, trial delivery experts, researchers and core project team members. PPIE is fully embedded within the consortium's five other WGs and steering group. The group's terms of reference, processes for effective working and PPIE evaluation were co-developed with PPIE contributors. Results: 11 PwP and 4 care partners have supported the PPIE WG and contributed to the development of processes for effective working. A mixed methods research-in-action study is ongoing to evaluate PPIE within the consortium. This includes the Patient Engagement in Research Scale -a quantitative PPIE quality measure; semi-structured interviews -identifying areas for improvement and overall impressions of involvement; process fidelity- recording adherence; project documentation review - identifying impact of PPIE on project outputs. Conclusions: We provide a practical example of PPIE in complex projects. Evaluating feasibility, experiences and impact of PPIE involvement in EJS ACT-PD will inform similar programs on effective strategies. This will help enable future patient-centered research.

For nearly every category of chronic disease, blacks with African American ancestry (AAs) bear a disproportionate disease burden in comparison to their non-Hispanic white (NHW) counterparts. The purpose of this study was to evaluate perceptions of a radio-based health communication strategy, geared towards AA adults and the medically underserved. The radio broadcast, titled "Closing the Gap in Healthcare, Inc. (CGHI)," is delivered by a well-known AA male physician in South Carolina. The mission of CGHI is to decrease health disparities in a four-county area of the South Carolina coastal region, defined as the "Lowcountry," by providing evidence-based health information to a broad community audience via radio broadcast messaging. To evaluate the impact of the CGHI, investigators conducted 12 focus groups (FGs) with community members from the broadcast coverage area to evaluate responses to FG questions based on 11 attributes of effective health communication. Potential FG participants were identified/recruited via a South Carolina-based marketing firm. The FGs conducted in the Sea Islands were culturally and racially homogenous. The investigators developed a FG interview guide. Before each FG started, the informed consent process was administered to each participant. Each two-hour FG was digitally recorded.

BACKGROUND: Given the importance of ethnic differences in the evaluation of various aspects of symptoms in patients with Parkinson's disease (PD), we present the formal procedure for completing the traditional Chinese translation of the International and Parkinson and Movement Disorder Society/UPDRS (MDS-UPDRS) and highlight the discrepancy in nonmotor symptoms (NMS) between patients in Eastern and Western countries. METHODS: A total of 350 native Chinese-speaking PD patients were recruited from multiple hospitals in Eastern countries; they completed the MDS-UPDRS. The translation process was executed and factor analysis was performed to determine the structure of the scale. Chi-squared and t tests were used to compare frequency and severity of PD symptoms between the Chinese-speaking and English-speaking groups (n = 876). RESULTS: NMS and motor symptoms were more severe in the Western population (Part I: t(1205) = 5.36, P < 0.0001; and Part III: t(1205) = 7.64, P < 0.0001); however, the prevalence of cognitive dysfunction and impairments in activities of daily living were more frequent in the Eastern patients. The comparative fit index was 0.93 or greater, and the exploratory factor analysis revealed compatible results between the translated scale and the original version. CONCLUSION: The traditional Chinese version of the MDS-UPDRS can be designated as an official translation of the original scale, and it is now available for use. Moreover, NMS in PD constitute a major issue worldwide, and the pattern of NMS among the Chinese population is more marked in terms of cognition-based symptoms and activities of daily living.
RESUMO
Sustaining important public or grant-funded services after initial funding is terminated is a major public health challenge. We investigated whether tobacco treatment services previously funded within a statewide tobacco control initiative could be sustained after state funding was terminated abruptly. We found that 2 key strategies-redefining the scope of services being offered and creative use of resources-were factors that determined whether some community agencies were able to sustain services at a much higher level than others after funding was discontinued. Understanding these strategies and developing them at a time when program funding is not being threatened is likely to increase program sustainability.

BACKGROUND: Movement towards evidence-based practices in many fields suggests that public health (PH) challenges may be better addressed if credible information about health risks and effective PH practices is readily available. However, research has shown that many PH information needs are unmet. In addition to reviewing relevant literature, this study performed a comprehensive review of existing information resources and collected data from two representative PH groups, focusing on identifying current practices, expressed information needs, and ideal systems for information access. METHODS: Nineteen individual interviews were conducted among employees of two domains in a state health department--communicable disease control and community health promotion. Subsequent focus groups gathered additional data on preferences for methods of information access and delivery as well as information format and content. Qualitative methods were used to identify themes in the interview and focus group transcripts. RESULTS: Informants expressed similar needs for improved information access including single portal access with a good search engine; automatic notification regarding newly available information; access to best practice information in many areas of interest that extend beyond biomedical subject matter; improved access to grey literature as well as to more systematic reviews, summaries, and full-text articles; better methods for indexing, filtering, and searching for information; and effective ways to archive information accessed. Informants expressed a preference for improving systems with which they were already familiar such as PubMed and listservs rather than introducing new systems of information organization and delivery. A hypothetical ideal model for information organization and delivery was developed based on informants' stated information needs and preferred means of delivery. Features of the model were endorsed by the subjects who reviewed it. CONCLUSION: Many critical information needs of PH practitioners are not being met efficiently or at all. We propose a dual strategy of: 1) promoting incremental improvements in existing information delivery systems based on the expressed preferences of the PH users of the systems and 2) the concurrent development and rigorous evaluation of new models of information organization and delivery that draw on successful resources already operating to deliver information to clinical medical practitioners.

We present the methodology and results of the clinimetric testing program for non-English translations of International Parkinson and Movement Disorder Society (MDS)-sponsored scales. The programs focus on the MDS revision of the UPDRS (MDS-UPDRS) and the Unified Dyskinesia Rating Scale (UDysRS). The original development teams of both the MDS-UPDRS and UDysRS envisioned official non-English translations and instituted a rigorous translation methodology. The formal process includes five core steps: (1) registration and start-up; (2) translation and independent back-translation; (3) cognitive pretesting to establish that the translation is clear and that it is comfortably administered to and completed by native-speaker raters and patients; (4) field testing in the native language using a large sample of Parkinson's disease patients; and (5) full clinimetric testing. To date, the MDS-UPDRS has 21 active language programs. Nine official translations are available, having completed all phases successfully, and the others are in different stages of development. For the UDysRS, 19 programs are active, with three official translations now available and the rest in development at different stages. Very few scales in neurology and none in movement disorders have fully validated translations, and this model may be adopted or modified by other scale programs to allow careful validation of translations. Having validated translations allows for maximal homogeneity of tools utilized in multicenter research or clinical trial programs.
RESUMO
BACKGROUND: Cognitive pretesting, a qualitative step in scale development, precedes field testing and assesses the difficulty of instrument completion for examiners and respondents. Cognitive pretesting assesses respondent interest, attention span, discomfort, and comprehension, and highlights problems with the logical structure of questions/response options that can affect understanding. In the past this approach was not consistently used in the development or revision of movement disorders scales. METHODS: We applied qualitative cognitive pretesting using testing guides in development of the Movement Disorder Society-sponsored revision of the Unified Parkinson's Disease Rating Scale (MDS-UPDRS). The guides were based on qualitative techniques, verbal probing and "think-aloud" interviewing, to identify problems with the scale from the patient and rater perspectives. English-speaking Parkinson's disease patients and movement disorders specialists (raters) from multiple specialty clinics in the United States, Western Europe and Canada used the MDS-UPDRS and completed the testing guides. RESULTS: Two rounds of cognitive pretesting were necessary before proceeding to field testing of the revised scale to assess clinimetric properties. Scale revisions based on cognitive pretesting included changes in phrasing, simplification of some questions, and addition of a reassuring statement explaining that not all PD patients experience the symptoms described in the questions. CONCLUSIONS: The strategy of incorporating cognitive pretesting into scale development and revision provides a model for other movement disorders scales. Cognitive pretesting is being used in translating the MDS-UPDRS into multiple languages to improve comprehension and acceptance and in the development of a new Unified Dyskinesia Rating Scale for Parkinson's disease patients.

The Unified Dyskinesia Rating Scale (UDysRS) assesses the severity and disability caused by dyskinesias in Parkinson's disease (PD). As part of the UDysRS development plan, the International Parkinson and Movement Disorder Society (MDS) established guidelines for official non-English translations. We present here the formal process for completing this program and the data on the first officially approved non-English version of the UDysRS (Spanish). The UDysRS translation program involves four steps: translation and back-translation; cognitive pretesting to ensure that raters and patients understand the scale and are comfortable with its content; field testing of the finalized version; and analysis of the factor structure of the tested version against the original English-language version. To be designated an official MDS translation, the confirmatory factor analysis comparative fit index (CFI) had to be ≥0.90. The Spanish UDysRS was tested in 253 native-Spanish-speaking patients with PD. For all four parts of the UDysRS, the CFI, was ≥0.94. Exploratory factor analyses of the Spanish version revealed a very clear factor structure, with three factors related to ON dyskinesia, OFF dystonia, and patient perceptions of the functional effect of dyskinesias. The Spanish version of the UDysRS successfully followed the MDS Translation Program protocol, reached the criterion to be designated as an official translation, and is now available on the MDS website for use.
RESUMO
BACKGROUND: The Movement Disorder Society (MDS)-sponsored revision of the Unified Parkinson's Disease (PD) Rating Scale (UPDRS) (MDS-UPDRS) has been developed and is now available in English. Part of the overall program includes the establishment of official non-English translations of the MDS-UPDRS. We present the process for completing the official Japanese translation of the MDS-UPDRS with clinimetric testing results. METHODS: In this trial, the MDS-UPDRS was translated into Japanese, underwent cognitive pre-testing, and the translation was modified after taking the results into account. The final translation was approved as Official Working Draft of the MDS-UPDRS Japanese version and tested in 365 native-Japanese-speaking patients with PD. Confirmatory analyses were used to determine whether the factor structure for the English-language MDS-UPDRS could be confirmed in data collected using the Official Working Draft of the Japanese translation. As a secondary analysis, we used exploratory factor analyses to examine the underlying factor structure without the constraint of a pre-specified factor organization. RESULTS: Confirmatory factor analysis revealed that Comparative Fit Index for all Parts of the MDS-UPDRS exceeded the minimal standard of 0.90 relative to the English version and therefore Japanese translation met the pre-specified criterion to be designated called an OFFICIAL MDS TRANSLATION. Secondary analyses revealed some differences between the English-language MDS-UPDRS and the Japanese translation, however, these differences were considered to be within an acceptable range. CONCLUSIONS: The Japanese version of the MDS-UPDRS met the criterion as an Official MDS Translation and is now available for use (www.movementdisorders.org).
