Influence of Adventist Spirituality on Self-Control and Perceived Stress Among Seventh-Day Adventist Adults in Coastal Peru

Background: Adventist spirituality has been identified as a relevant psychosocial resource for emotional well-being; however, evidence on its relationship with self-control and perceived stress in specific religious populations remains limited. Objective: The aim of this study was to examine the associations between Adventist spirituality, self-control, and perceived stress in a sample of adults belonging to the Seventh-day Adventist Church and residing in coastal regions of Peru. Methods: A cross-sectional study was conducted between December 2025 and January 2026 with 506 Seventh-day Adventist adults who completed an online questionnaire. Adventist spirituality was assessed using the Mission Commitment Questionnaire, which captures religious–spiritual commitment through three dimensions: personal devotion, participation, and witnessing. Self-control and perceived stress were measured using standardized scales. Data were analyzed using partial least squares structural equation modeling. Results: The constructs showed adequate internal consistency, with Cronbach’s alpha values ranging from 0.875 to 0.951 and composite reliability values ranging from 0.906 to 0.956. Adventist spirituality was positively associated with self-control (β = 0.479, p < 0.001) and negatively associated with perceived stress (β = −0.457, p < 0.001). Personal devotion showed the strongest contribution to the higher-order spirituality construct. The model explained 22.9% of the variance in self-control and 20.9% of the variance in perceived stress. Conclusions: Adventist spirituality, particularly personal devotion, was associated with higher self-control and lower perceived stress. Although the cross-sectional design does not allow causal inference, the findings support the relevance of Adventist spirituality as a psychosocial resource linked to emotional well-being in this religious population and justify future longitudinal studies.
