The role of social context in risky decision-making: Presence of friend and low resistance to peer influence increase risky decision-making.

Following sociocultural and personality theory, the current study addresses the need to investigate the influence of the social context and related personality variables on risky decision-making. Risky decision-making was assessed in six daily-life scenarios in a sample of 357 adult participants, ages 18-75. Scenarios differed regarding competition (competitive vs. non-competitive) and presence of others (alone, with friends, or with acquaintances). Additionally, the personality variables ego-strength, agreeableness, and resistance-to-peer influence as well as demographic variables were assessed. Results showed that participants made more risky decisions in the non-competitive scenarios and in the scenarios when they were accompanied by a friend compared to when they were alone. Regression analyses revealed that men made more risky decisions than women. High resistance-to-peer influence and agreeableness whereas related to fewer risky decisions. Overall, results showed the strong influence of social and personality factors on risky decision-making which could have implications for prevention programmes. Further, these results show that a pure cognitive approach to the study of risky decision-making is too narrow. Considering cognition, social context, and personality traits together seems to be a promising approach for the study of risky daily-life decisions.
