Habitability and psychosocial vulnerability to floods in Escuinapa and Rosario

Floods affect the habitability of exposed dwellings not only through material damage but also through the worry they cause and through reliance on neighbourly and institutional support. Using the preliminary data cut from the pilot survey of project FZ-HAB-0016 on the Factoriza UAS platform, this study described the initial behaviour of a fifteen-item scale with three dimensions, Worry about floods, Housing resistance to heavy rain and Neighbour support during floods, administered in Escuinapa and El Rosario, Sinaloa, Mexico. With a cross-sectional design, 6 cases out of a target of 100 were analysed while data collection remained open. Descriptive statistics, Cronbach’s alpha, McDonald’s omega total and Spearman correlations between dimensions were estimated, and an exploratory factor analysis was attempted. Internal consistency was α = .843 and ω = .870 for Worry, α = .739 and ω = .757 for Support, and α = .727 and ω = .772 for Housing resistance, excluding R6, which showed no variance. The factor analysis was not interpretable: sampling adequacy and Bartlett’s test could not be computed and the solution showed Heywood cases. Correlations between dimensions had confidence intervals that included zero. Items R4 and R12 were the least consistent with their dimensions. The findings do not yet provide structural validity evidence and point to specific revisions of the instrument before data collection is completed.
