The Credibility of Grounded Theory*: Strategies for Qualitative Research
... However, given the particularity of the context of this study area and the complexity of the concept of provider bias, one could argue that wanting to replicate the data would be naYve and unfeasible (Lincoln and Guba, 1985). Rather, a sense of 'trustworthiness' (Glaser and Strauss, 1967) is a key to appraise the 'soundness' of this study (Ritchie and Lewis, 2003). In order to increase the trustworthiness, the detailed procedures that have led to the results and conclusions of this study are exposed (Seale, 1999). ...
... Validity is referred to as 'correctness', 'credibility' or 'plausibility' of research findings (Ritchie and Lewis, 2003;Glaser and Strauss, 1967). Validity has two dimensions: internal validity referring to 'the extent to which an account accurately represents the social phenomena to which it refers' (Hammersley, 1990) and external validity referring to the extent to which generated concepts and findings can be applied to other populations or context (Lincoln and Guba, 1985). ...

Internal validation was verified by checking' accuracy of fit' and testing derived concepts from one part of the data (one provider or focus group) on other narrative data (another provider or focus group) (Glaser and Strauss, 1967). ...
p>This thesis highlights the extent of ethnic diversity in reproductive behaviour in terms of fertility, use of family planning and modern pregnancy related care in Guatemala and explores some of the reasons behind this diversity. Guatemala is one of the poorest countries in Latin America and is characterised by extremely unequal distributions of socio-economic resources between its different social and ethnic groups. This study uses various existing data sources, original data, methodologies and a qualitative and quantitative approach to pursue its aim.
This thesis consists of four papers and includes a case-study of the understudied Ch’orti area. The first paper contributes to the understanding of fertility patterns in urban and rural areas by using the existing survey and census data for Guatemala. The analysis identified a very slow fertility decline since the early 1980s in rural areas, stagnation in fertility trends in urban areas until the end of the 1990s and a sharp decline in overall fertility since then. The analysis of the census data showed the impact of the ethnic composition and diversity on fertility at the level of the municipio. The second and third paper present the results of two household surveys, one undertaken in 1994 in two indigenous villages ( aldeas) and one in 2001 in Jocotán town, the capital of the Ch’orti area, on the use of family planning and modern pregnancy related care among different ethnic groups. This survey used the alternative approach of classifying ethnic groups, who were not identifiable by language and dress, according to self-identification and place of birth. The results showed significant differences in reproductive behaviour between the ethnic groups living in close proximity of one another, demonstrating the extent of ethnic diversity in reproductive behaviour in Guatemala. The fourth and last paper explores which factors could be responsible for the lower uptake of contraception among the indigenous communities in the Ch’orti area. The results suggest that geographical access, quality of care and medical barriers such as provider bias, at existing family planning services and lack of prioritisation of family planning policies contribute to persistent low uptake of contraception among the indigenous communities in Guatemala.</p
Introduction:
Latinos are underrepresented in brain autopsy research on Alzheimer's disease and related dementias (ADRD). The study's purpose is to identify Latinos' attitudes about brain donation (BD) to inform methods by which researchers can increase autopsy consent.
Methods:
Forty Latinos (mean age: 59.4 years) completed a semi-structured interview and were presented with educational information about BD. Participants completed a questionnaire assessing their understanding of BD and willingness to donate their brain for research.
Results:
Among participants, there was near unanimous support for BD to study ADRD after hearing educational information. However, prior to the information presented, participants reported a lack of knowledge about BD and demonstrated a possibility that misunderstandings about BD may affect participation.
Discussion:
While nearly all study participants agree that donating is beneficial for research and for future generations, the lack of BD information must be addressed to help support positive attitudes and willingness for participation.
