Le profil des récidivistes en matière de conduite avec capacités affaiblies par l’alcool : une étude des caractéristiques neuropsychologiques et psychologiques des contrevenants selon leur sexe

During the past decade, female driving while impaired by alcohol (DWIA) have gathered more attention as DWIA is increasing in females while decreasing in males. Data suggest that DWIA risk in females is associated with distinct psychological characteristics from those of male offenders (i.e. more alcohol and drug-related problems, and psychopathology, while less sensation seeking and delinquency). Despite this differential profile, female DWIA offenders remain a highly unknown population, especially regarding recidivism. In addition, growing data, mostly based on male offenders, support the idea that cognitive limitations are present in recidivists and represent a potential underlying mechanism to their behavior. Exploratory data collected in female offenders and data from other germane research fields suggest that female recidivists are cognitively distinct, especially in terms of executive functioning that could be relatively spared while their visuospatial functioning would be more impaired in comparison of male offenders. The objective of this dissertation is to enhance knowledge on female recidivist’s characteristics. This will allow a better comprehension of the heterogeneity of DWIA recidivist’s population and generate hypotheses concerning potential mechanisms that underlie their repetitive DWIA behavior. The thesis is especially targeting neuropsychological and psychological characteristics of female recidivists. More specifically, the study’s first aim is to examine DWIA recidivists sex differences regarding visuospatial functioning, attentional and executive functions (i.e. cognitive flexibility, abstraction, inhibition). The secondary objective is to compare offenders on psychological characteristics (alcohol and drug use, impulsivity, sensation seeking, anxiety, depression and antisocial tendencies). It is hypothesized that female and male DWIA recidivists would present a lower performance than their respective non-offender counterparts in terms of visuospatial, attentional and executive functions. In addition, it is expected that female recidivists would present a lower visuospatial performance than male recidivists. It is also hypothesized that male recidivists would exhibit lower attentional and executive performances than female recidivists. Regarding psychological characteristics, it is expected that recidivists would present more alcohol and drug-related problems, impulsivity, sensations seeking and psychopathology (antisocial tendencies, depression, anxiety) than non-offenders and that female recidivists would present more alcohol and drug-related problems, depression and anxiety than male recidivists. Finally, hypotheses suggest that male recidivists would present more impulsivity, sensations seeking and antisocial tendencies than female recidivists. These hypotheses are partially supported as male recidivists (n = 39) present lower attentional and executive performances than male non-offenders (n = 20) and female recidivists (n = 20). However, female recidivists do not significantly differ from female non-offenders (n = 20) in terms of neuropsychological functioning. In regard to psychological characteristics, results partially support hypotheses. The discussion highlights female and male similar characteristics except for attentional and executive mechanisms that seem to play a role in male recidivism, while it is apparently not the case in female recidivists whose behavior could be more situational. The need for further studies with experimental design as well as difficulty in female recruitment are discussed.
