Conducting member checking within a qualitative case study on health-related behaviours in a large European city: Appraising interpretations and co-constructing findings.

Although member checking is a well-established strategy for appraising credibility, there is a lack of research reporting procedures and outcomes when using this strategy. In recent years, scholars have implemented new member checking strategies along with several epistemological stances. In this work, researchers conducted member checking in three neighbourhoods with different socioeconomic status in Madrid, Spain. Attendance at member checking meetings was lower than expected. Member checking meetings were conducted in public halls within each neighbourhood and lasted approximately 2 hours. During the first hour, researchers introduced the aim of the meetings and shared summarized research findings with attendees using a slideshow. During the second hour, attendees had the opportunity to comment on any aspect of the research. Researchers used grounded theory coding strategies and a constructivist approach informed the analysis of the transcribed member checking meetings. One core category emerged, and it was named 'Co-constructing findings and side effects of the interaction between researchers and participants in member checking'. Member checking attendees contributed to co-constructing findings by means of underscore and disagreement. It is possible that these meetings might have caused side effects such as unintended comparisons between neighbourhoods and negative health-related behaviours. Attendees wondered how the findings could improve their neighbourhoods. The meetings allowed interaction between participants and researchers and resulted in appraising and co-constructing qualitative research findings. More research is needed to advance knowledge about member checking.

Factors influencing dietary inequalities among adolescents in Madrid and Bilbao: a qualitative research project.

OBJECTIVE: To describe the design and methodology of a qualitative study to explore the main factors influencing dietary inequalities in adolescents in Madrid and Bilbao, Spain. METHOD: The study area included six neighborhoods (three in each city) of different socioeconomic status (SES): low, medium, and high. We sampled 12 secondary schools (six in each city: two per socioeconomic level). Our methodology comprised: 1) developing an ad hoc index to classify all neighborhoods according to their SES; 2) selecting the study area and sample; 3) conducting semi-structured interviews (n=36) and focus groups (n=24). Grounded theory and phenomenological analysis will be employed in data analysis. Initially, we found factors influencing in adolescents' diet such as gender, family environment, and SES. CONCLUSIONS: Systematizing the selection of neighborhoods and secondary schools, along with using appropriate methods, could serve as a foundation for future studies on health inequalities among adolescents.
