Abstract

Although psychopathy has historically been associated with a lack of emotion, recent research has suggested that psychopathy may represent a tendency to externalize the experience of unpleasant emotions, including shame, which could be seen as an adaptive strategy within an evolutionary framework. However, more empirical research is needed to build on this argument. This study tested a novel evolutionary-based model involving pathways associating the impact of harsh rearing experiences (warmth and safeness experiences and traumatic shameful experiences) with psychopathic traits as well as the indirect effects of external shame and shame coping strategies in this association. This study also tested the invariance of this model across gender. A youth community sample (N = 703; 58.9% girls) completed self-report questionnaires on the impact of harsh rearing experiences, external shame, shame coping strategies, and psychopathic traits. The results suggested that the impact of harsh rearing experiences was directly and indirectly (through external shame and shame coping strategies) associated with psychopathic traits. The model partially explained the endorsement of psychopathic traits in boys and girls, although gender differences were found in some of the pathways. These findings offer support for conceptualizing psychopathic traits as an adaptive strategy to cope with the impact of harsh rearing experiences, opening new perspectives for prevention and treatment.

Notes

  1. From an evolutionary perspective, an adaptive response does not necessarily mean psychological well-being or socially valued outcomes. On the contrary, it means that, at least in the short run and in that particular environment, those strategies/traits are increased based on evolutionary tradeoffs (Del Giudice 2016).

  2. Examples of professions in the high socioeconomic status groups are judges, higher education teachers, or MDs; examples for the medium socioeconomic status group are nurses, psychologists, or school teachers; and examples for the low socioeconomic group are farmers, cleaning staff, or undifferentiated worker. When the mothers’ and fathers’ professions were classified into different socioeconomic status, the highest SES coding was attributed to the family.

  3. We also tested an alternative model in which psychopathic traits were used as independent variables and the impacts of harsh rearing experiences were used as dependent variables. Indirect effects between the independent and dependent variables were also considered through external shame and shame coping strategies. The model fit indicators were not acceptable (X2(18) = 719.459, p < .000; RMSEA = .235; CFI = .579; SRMR = .110) and were worse than those found for the baseline model under scrutiny in the current work.
