Cultural Spanish adaptation, factor structure, and reliability of implementation science instruments for suicide prevention.

Research on the implementation of community gatekeeper training interventions for suicide prevention in Spanish-speaking countries is limited. Gatekeepers identify warning signs of suicidal behavior in at-risk population and refer them to specialized mental health care. To identify factors that influence the implementation of evidence-based practices, standardized measures are needed in Spanish. We culturally adapted and evaluated the factor structure and reliability of two measures for use in the Mexican population: the final version of Acceptability, Appropriateness, and Feasibility of the Intervention (Weiner et al., 2017), and the Organizational Readiness for Implementing Change (ORIC; Shea et al., 2014). Our study consisted of two consecutive phases. The first addressed the cross-cultural adaptation. In the second phase, we administered an online survey to a nonrandom sample of 453 middle school personnel and performed a confirmatory factor analysis (CFA). Participants were 73.95% female, 25.17% male, and 0.88% nonbinary/other and came from the 32 Mexican states. CFA indices for the Mexican Spanish version of the acceptability, appropriateness, and feasibility measure yielded values of comparative fit index (CFI) = 0.96, Tucker-Lewis fit index (TLI) = 0.94, root-mean-square error of approximation (RMSEA) = 0.05, and standardized root-mean-square residual (SRMR) = 0.03. Internal consistency was Ω = 0.95. CFA indices of the Mexican Spanish version of the ORIC were CFI = 0.95, TLI = 0.93, RMSEA = 0.08, and SRMR = 0.03, and internal consistency was Ω = 0.94. We conclude that both instruments show preliminary psychometric properties that support their validity and reliability in the Mexican Spanish-speaking context. These findings promise to drive research on the implementation of gatekeeper interventions and other evidence-based practices in Spanish-speaking school settings.
