Abstract
Background
There is growing interest in the role of religion in psychiatric disorders. Impulsivity is a psychological trait associated with acting without thinking, with a decision process favoring short-term outcomes without further consideration of its consequences, and is a risk factor for the development of mental disorders.
Objective
In this study, the objective was to analyze the role of religiosity as a possible moderator between the association of impulsivity and internalizing psychiatric symptoms.
Methods
The hypothesis was assessed in a cross-sectional study enrolling 366 adults evaluated using the abbreviated version of the Barratt Impulsiveness Scale-11, the Self Reporting Questionnaire-20, and the Duke Religion Index.
Results
Internalizing symptoms were significantly influenced by an interaction between religiosity and impulsivity. Religiosity acted as a protective factor against internalizing symptoms only for participants with high impulsivity.
Discussion
The results suggest a moderation role of religiosity in the association of impulsivity with internalizing symptoms.

The figure shows the estimated marginal means (corrected by age, education and socioeconomic status) of internalizing symptoms measured by Self-Reporting Questionnaire 20 stratified by religiosity and impulsivity. There was a significant interaction between religiosity and impulsivity (F = 44.64, p = 0.022, ηp2 = 0.03). Participants with high religiosity (measured by a standard score of Duke Religion Index) showed less internalizing symptoms than participants with low religiosity (p = 0.007), but only in the context of with high impulsivity (above percentile 75 in the Abbreviated version of Barratt Impulsiveness Scale). ** p < 0.01.
