Tiempo de pertenencia y percepciones en movimientos sociales de salud pública del Distrito Nacional, República Dominicana

Introduction: Public health social movements bring together members with different lengths of membership, but it is unknown whether this tenure differentiates their perceptions of demand impact, population priorities, and technology. Objective: To determine the association between length of membership and perceived impact of demands, prioritization of population groups, and valuation of technology among members of public health social movements in the National District, Dominican Republic. Methods: Secondary, observational, cross-sectional, analytical study of a survey of 117 members (convenience sampling) from a broader study. Bivariate associations between length of membership, role, sex, and age and four perceived outcomes were assessed using the chi-square test and Cramér's V, with Bonferroni correction within the primary and exploratory families. Results: Length of membership was associated with perceived impact of demands (p < 0.001; V = 0.55) and with prioritized population group (p < 0.001; V = 0.38), but not with technology valuation (conditional p = 0.160; V = 0.21). With less than one year of membership, 58.3% perceived a large impact, versus 0.0% with more than six years. Eight of thirteen exploratory associations remained significant after Bonferroni correction. Conclusions: Length of membership showed the largest association with perceived impact, but not with technology valuation; its strong relationship with role precludes establishing an independent effect. The cross-sectional design and the retrospective valuation of the pandemic limit inference.
