“…The Delphi method is a consensus technique that collects expert opinions through several rounds of surveys or interviews, and is characterized by anonymity, iteration, controlled feedback, and statistical group response (expression of the degree of consensus within a group). [22][23][24] For the first round, we requested that each Delphi participant indicate the top five to ten barriers from among all the barriers identified in the content analysis. For the second round, we presented each participant with the sum total of anonymous votes for all barriers from the first round, and requested that each participant again indicate the top five to ten barriers.…”

BACKGROUND: Hypertension, the leading global risk factor for mortality, is characterized by low treatment and control rates in low-and middle-income countries. Poor linkage to hypertension care contributes to poor outcomes for patients. However, specific factors influencing linkage to hypertension care are not well known. OBJECTIVE: To evaluate factors influencing linkage to hypertension care in rural western Kenya. DESIGN: Qualitative research study using a modified Health Belief Model that incorporates the impact of emotional and environmental factors on behavior. PARTICIPANTS: Mabaraza (traditional community assembly) participants (n=242) responded to an open invitation to residents in their respective communities. Focus groups, formed by purposive sampling, consisted of hypertensive individuals, at-large community members, and community health workers (n=169). APPROACH: We performed content analysis of the transcripts with NVivo 10 software, using both deductive and inductive codes. We used a two-round Delphi method to rank the barriers identified in the content analysis. We selected factors using triangulation of frequency of codes and themes from the transcripts, in addition to the results of the Delphi exercise. Sociodemographic characteristics of participants were summarized using descriptive statistics. KEY RESULTS: We identified 27 barriers to linkage to hypertension care, grouped into individual (cognitive and emotional) and environmental factors. Cognitive factors included the asymptomatic nature of hypertension and limited information. Emotional factors included fear of being a burden to the family and fear of being screened for stigmatized diseases such as HIV. Environmental factors were divided into physical (e.g. distance), socioeconomic (e.g. poverty), and health system factors (e.g. popularity of alternative therapies). The Delphi results were generally consistent with the findings from the content analysis. CONCLUSIONS: Individual and environmental factors are barriers to linkage to hypertension care in rural western Kenya. Our analysis provides new insights and methodological approaches that may be relevant to other lowresource settings worldwide. INTRODUCTIONCardiovascular disease is the leading cause of mortality worldwide, with 80 % of cardiovascular deaths occurring in lowand middle-income countries (LMICs). 1 Hypertension, a major risk factor for cardiovascular disease, 2 is the leading global risk for mortality. 3 Over the next decade, the global cost of suboptimal blood pressure may approach $1 trillion. 4 Unless it is adequately controlled, hypertension will continue to be responsible for significant morbidity and mortality worldwide. 5 In many LMICs, however, the rates of hypertension treatment and control are low. 6 In Kenya, hypertension treatment and control rates have been reported at 9 % and 3 %, respectively. 7 Poor linkage to hypertension care, manifested as delays in seeking care after screening and referral, has been shown to be associated with increased mortality among pre...

“…In addition to a linguistically accurate translation of the CAPS-5 that would correspond to the official Dutch translation of the DSM-5 ensuring content validity, it was deemed important to create a translation that would optimally fit into clinical and research practice. This led to the development and realization of a novel stepped crowd-translation process to engender the Dutch CAPS-5, which involved a crowd of Dutch psychotrauma professionals (clinicians as well as researchers) and was based on the principles of a cross-cultural adaptation process (Beaton et al, 2000) as well as the Delphi method (Dalkey, 1969; Dalkey & Helmer, 1963; Hsu & Sandford, 2007) for consensus-building by expert-rounds. This process encompassed six translation steps that were carried out to develop the Dutch version of the CAPS-5 (Figure 1).…”

“…This paper describes an innovative approach of translation to ensure cross-cultural validity of diagnostic instruments using a combination of principles of a cross-cultural adaptation process (Beaton et al, 2000) and the Delphi method (Dalkey, 1969; Dalkey & Helmer, 1963; Hsu & Sandford, 2007). By involving multiple experts in different rounds the employed approach of translation was instrumental in achieving an instrument that was broadly supported among experts.…”

Background: In 2013, the Clinician-Administered PTSD Scale, the golden standard to assess PTSD, was adapted to the DSM-5 (CAPS-5).Objective: This project aimed to develop a clinically relevant Dutch translation of the CAPS-5 and to investigate its psychometric properties.Method: We conducted a stepped translation including Delphi rounds with a crowd of 44 Dutch psychotrauma experts and five senior psychotrauma experts. Using partial crowd-translations, two professional translations and the official Dutch translation of the DSM-5, each senior expert aggregated one independent translation. Consensus was reached plenary. After back-translation, comparison with the original CAPS-5 and field testing, a last round with the senior experts resulted in the final version. After implementation clinicians conducted CAPS-5 interviews with 669 trauma-exposed individuals referred for specialized diagnostic assessment. Reliability of the Dutch CAPS-5 was investigated through internal consistency and interrater reliability analyses, and construct validity through confirmatory factor analysis (CFA).Results: CAPS-5 total severity score showed high internal consistency (α = .90) and interrater reliability (ICC = .98, 95% CI: .94–.99). CAPS-5 diagnosis showed modest interrater reliability (kappa = .59, 95% CI: .20–.98). CFA with alternative PTSD models revealed adequate support for the DSM-5 four-factor model, but a six-factor (Anhedonia) model fit the data best.Conclusions: The Dutch CAPS-5 is a carefully translated instrument with adequate psychometric properties. Current results add to the growing support for more refined (six and seven) factor models for DSM-5 PTSD indicating that the validity and clinical implications of these models should be objective of further research.

“…Three methods were used to estimate the population: an indirect approach, 12 a representative population survey, 13 and a modified Delphi technique. [14][15][16] The utility of each method is discussed and the estimates are triangulated to provide a single estimate of YBMSM living on the SSC.…”

Estimating the Number of Young Black Men who have Sex with Men (YBMSM) on the South Side of Chicago: Towards HIV Elimination within US Urban Communities

et al. 2013

The rate of HIV infection among young Black men who have sex with men (YBMSM) aged 16-29 is increasing significantly in the United States. Prevention in this population would considerably impact future health-care resources given the need for lifelong antiretrovirals. A YBMSM population estimate is needed to assist HIV prevention program planning. This analysis estimates the number of YBMSM aged 16-29 living on the south side of Chicago (SSC), the Chicago HIV epicenter, as the first step in eliminating HIV in this population. Three methods were utilized to estimate the number of YBMSM in the SSC. First, an indirect approach following the formula a=k/b; where a = the estimated number of YBMSM, k = the average YBMSM HIV prevalence estimate, and b=the YBMSM population-based HIV seropositivity rate. Second, data from the most recent National Survey of Family Growth (NSFG) was used to estimate the proportion of Black men who report having sex with a man. Third, a modified Delphi approach was used, which averaged community expert estimates. The indirect approach yielded an average estimate of 11.7 % YBMSM, the NSFG yielded a 4.2 % (95 % CI 2.28-6.21) estimate, and the modified Delphi approach yielded estimates of 3.0 % (2.3-3.6), 16.8 % (14.5-19.1), and 25 % (22.0-27.0); an average of 14.9 %. The crude average of the three methods was 10.2 %. Applied to SSC, this results to 5,578 YBMSM. The estimate of 5,578 YBMSM represents a group that can be feasibly reached with HIV prevention efforts. Population estimates of those most at risk for HIV will help public health officials allocate resources, offering potential for elimination of new HIV cases.
