Validation of a scale for assessing attitudes towards outcomes of genetic cancer testing among primary care providers and breast specialists.

ABSTRACT:

Objective

To develop a generic scale for assessing attitudes towards genetic testing and to psychometrically assess these attitudes in the context of BRCA1/2 among a sample of French general practitioners, breast specialists and gyneco-obstetricians.

Study design and setting

Nested within the questionnaire developed for the European InCRisC (International Cancer Risk Communication Study) project were 14 items assessing expected benefits (8 items) and drawbacks (6 items) of the process of breast/ovarian genetic cancer testing (BRCA1/2). Another item assessed agreement with the statement that, overall, the expected health benefits of BRCA1/2 testing exceeded its drawbacks, thereby justifying its prescription. The questionnaire was mailed to a sample of 1,852 French doctors. Of these, 182 breast specialists, 275 general practitioners and 294 gyneco-obstetricians completed and returned the questionnaire to the research team. Principal Component Analysis, Cronbach's ? coefficient, and Pearson's correlation coefficients were used in the statistical analyses of collected data.

Results

Three dimensions emerged from the respondents' responses, and were classified under the headings: "Anxiety, Conflict and Discrimination", "Risk Information", and "Prevention and Surveillance". Cronbach's ? coefficient for the 3 dimensions was 0.79, 0.76 and 0.62, respectively, and each dimension exhibited strong correlation with the overall indicator of agreement (criterion validity).

Conclusions

The validation process of the 15 items regarding BRCA1/2 testing revealed satisfactory psychometric properties for the creation of a new scale entitled the Attitudes Towards Genetic Testing for BRCA1/2 (ATGT-BRCA1/2) Scale. Further testing is required to confirm the validity of this tool which could be used generically in other genetic contexts.

Project description:IntroductionAssessment of attitudes of health care professionals is important as negative attitude could constitute a major deterrent to care-seeking by persons affected by neglected tropical diseases (NTDs) such as leprosy. Leprosy continues to pose a major disease burden in India with an annual new case detection rate of 10.17 per 100,000 population. This paper reports on the development and validation of a culturally appropriate scale to measure attitude of health care providers (HCPs) towards persons affected by leprosy in Tamil Nadu, India.Methodology/principal findingsThe Affective, Behavioural and Cognitive (ABC) model of attitudes guided the development of the scale. Steps in scale development included qualitative interviews and focus group discussions with medical officers and paramedical staff selected from high prevalence districts in Tamil Nadu, India which informed the development of the draft scale. Reviews of existing attitude questionnaires in related areas further contributed to scale development and together helped to generate a large pool of items which was then subjected to Thurston's scaling method for selection of items from this pool. Face and content validity were obtained, following which internal consistency and test, re-test reliability were assessed. Scaling exercise resulted in 11 items being discarded from an initial pool of 38, owing to the poor agreement among experts regarding relevance. Face and content validity were good with experts endorsing relevance and applicability of items. The intra-class correlation coefficient (ICC) for test re-test reliability of the 27 item scale was 0.6 (95% CI: 0.20-0.78) indicating marginal intra-class correlation. The overall Cronbach's alpha was 0.85 while the alphas for each of the affective and behavioural components was good at 0.78 and 0.69 respectively indicating a good degree of consistency and homogeneity between items but the alpha for the cognitive component was low at 0.53.ConclusionsThe ABC model of attitudes guided the development of the scale, ensured a mix of 27 items tapping into the three domains of Affect, Behaviour and Cognition which best explained the attitude construct. With good validity and alphas for each of the affective, behavioural components and overall alpha estimates, this scale can be a valuable tool to provide accurate estimates of the true attitudes held by HCPs. This, in turn, would be useful to obtain insights for appropriate intervention programmes that would help change negative attitudes of HCPs towards persons affected by leprosy. With some adaptations, the scales can be validated for other NTDs as well.

Project description:BackgroundDespite efforts to improve access to Medications for Opioid Use Disorder (MOUD), such as buprenorphine, the number of opioid overdoses in the United States continues to rise. In April 2021, the Department of Health and Human Services removed the mandatory training requirement to obtain a buprenorphine waiver; the goal was to encourage more providers to prescribe buprenorphine, thus improving access. Little is known about the attitudes on buprenorphine prescribing after this policy change.ObjectiveThe primary objective was to assess attitudes among primary care providers toward the removal of the buprenorphine waiver training requirement. A secondary objective was to identify other barriers to prescribing buprenorphine.MethodsWe conducted a survey between September 15 and October 13, 2021 to assess the overall beliefs on the effectiveness of MOUD and attitudes toward the removal of the waiver training, current knowledge of buprenorphine, current practice styles related to screening for and treating OUD, and attitudes toward prescribing buprenorphine in the future. This survey was sent to 890 Mayo Clinic primary care providers in 5 US states.ResultsOne hundred twenty-three respondents (13.8%) completed the survey; 35.8% respondents agreed that the removal of the waiver training was a positive step. These respondents expressed a greater familiarity with the different formulations, pharmacology, and titration of buprenorphine. This group was also more likely to prescribe (or continue to prescribe) buprenorphine in the future. Approximately one-third (34.4%) of respondents reported perceived institutional support in prescribing buprenorphine. This group expressed greater confidence in diagnosing OUD, had greater familiarity with the different formulations, pharmacology, and titration of buprenorphine, and was more likely to prescribe (or continue to prescribe) buprenorphine in the future. Respondents who have been in practice for 11 to 20 years since completion of training were most likely to refer all OUD patients to specialists.ConclusionsResults of our survey suggests that simply removing the mandatory waiver training requirement is insufficient in positively changing attitudes toward buprenorphine prescribing. A key barrier is the perceived lack of institutional support. Future studies investigating effective ways to provide such support may help improve providers' willingness to prescribe buprenorphine.

Project description:Introduction:Emergency care research in Africa is not on par with other world regions. The study aimed to assess the perceptions and practices towards research among current emergency care providers in Africa. Methods:A survey was sent to all individual members of the African Federation of Emergency Medicine. The survey was available in English and French. Results:One hundred and sixty-eight responses were analysed (invited n = 540, responded n = 188, 34.8%, excluded n = 20). Responders' mean age was 36.3 years (SD = 9.1); 122 (72.6%) were male, 104 (61.9%) were doctors, and 127 (75.6%) were African trained. Thirty-seven (22%) have never been involved in research; 33 (19.6%) have been involved in ?5 research projects. African related projects were mostly relevant to African audiences (n = 106, 63.1%). Ninety-four (56%) participants have never published. Forty-one (24.4%) were not willing to publish in open access journals requesting a publication fee; 65 (38.7%) will consider open access journals if fees are sponsored. Eighty responders (47.6%) frequently experienced access block to original articles due to subscription charges. Lack of research funding (n = 108, 64.3%), lack of research training (n = 86, 51.2%), and lack of allocated research time (n = 76, 45.2%) were the main barriers to research involvement. Improvement of research skills (n = 118, 70.2%) and having research published (n = 117, 69.6%) were the top motivational factors selected. Responders agreed that research promotes critical thinking (n = 137, 81.5%) and serve as an important educational tool (n = 134, 80.4%). However, 134 (79.8%) feel that emergency care workers need to be shown how to use research to improve clinical practice. Most agreed that insufficient emergency care research is being conducted in Africa (n = 113, 67.3%). Discussion:There is scope to increase research involvement in emergency care in Africa, but solutions need to be find to address lack of research-related funding, training and time.
