'How I Think Questionnaire' (HIT) is used to measure self-serving cognitive distortions among delinquents. Previously validated on Americans, this instrument was translated, adapted and validated for French-speaking teens. To assess convergent and discriminant validity, 336 adolescents with externalizing behaviors in Québec (Canada) completed the HIT, the Self-Reported Delinquency Scale (SRD), and the Auto-aggression Questionnaire. There were 165 boys and 171 girls with M(age) = 16.4 years (SD = 0.5) who received services under the Youth Criminal Justice Act (n = 145) or the Youth Protection Act (n = 191). HIT and SRD total scores were correlated (0.51, p < 0.01). On the HIT, past suicidal attempting delinquents were not significantly different than non-suicide attempting delinquents; also delinquents living in closed detention facilities had more self-serving cognitive distortions than delinquents living in open facilities or under probation in the community. This French-language version of the HIT is a reliable and valid measure.

Climate change is reshaping agriculture and insect biodiversity worldwide. With rising temperatures, insect species with narrow thermal margins are expected to be pushed beyond their thermal limits, and losses related to herbivory and diseases transmitted by them will be experienced in new regions. Several previous studies have investigated this phenomenon in tropical and temperate regions, locally and globally; however, here, it is proposed that climate change impact on agriculture can be traced through the study of Nearctic migratory insects, specifically leafhoppers. To test this hypothesis, leafhoppers in strawberry fields located in the province of Québec, eastern Canada, were evaluated. The strawberry-leafhopper pathosystem offers a unique opportunity because leafhoppers can transmit, among other diseases, strawberry green petal disease (SbGP), which is associated with pathogenic phytoplasmas. Here, we found that in the last ten years, the number of leafhoppers has been increasing in correspondence with the number of SbGP cases detected in eastern Canada, reporting for the first time ten species new to eastern Canada and two to the country, although the leafhopper diversity has been seriously affected. Our model using more than 34 000 leafhoppers showed that their abundance is influenced by temperature, a factor that we found also influences the microbiome associated withMacrosteles quadrilineatus, which was one of the most abundant leafhoppers we observed. One of our most striking findings is that none of the insecticides used by strawberry growers can control leafhopper incidence, which could be linked to microbiome changes induced by changing temperatures. We suggest that Nearctic leafhoppers can be used as sentinels to trace the multilayered effects of climate change in agriculture.

L’épuisement professionnel a des conséquences néfastes pour l’individu, l’organisation et la société. Les facteurs de risque organisationnels de l’épuisement professionnel ont été étudiés empiriquement, et il existe des outils pour les évaluer, tel la Areas of Worklife Scale (AWS; Leiter & Maslach, 2002). Les facteurs de risque individuels n’ont pas reçu la même attention systématique et aucun instrument ne permet d’en faire un portrait. Le questionnaire Style personnel au travail (SPT; Papineau, Desjardins, Legault & Demers, 2014) a été développé pour combler cette lacune, après une recension des facteurs corrélés au Maslach Burnout Inventory (MBI; Maslach & Jackson, 1981). L’arbre décisionnel de Kraemer et al. (1997) a été utilisé pour déterminer les facteurs de risque individuels recensés qui étaient modifiables, c’est-à-dire ceux qui pouvaient être traités par une intervention. Le SPT comporte 26 items répartis en 6 facteurs (perfectionnisme, faible estime de soi, intolérance à l’incertitude, pression de performance, faible affirmation de soi et tendance à s’inquiéter). Sa fidélité ainsi que sa validité factorielle et convergente ont été évaluées à l’aide de deux études (Étude 1, N = 233; Étude 2, N = 417). Des corrélations positives ont été obtenues entre le SPT et le MBI-General Survey (MBI-GS; Schaufeli & Leiter, 1996). Ces résultats indiquent que les propriétés psychométriques du SPT sont adéquates et que les facteurs du SPT sont corrélés avec au moins une dimension du MBI-GS. Le SPT s’avère être un instrument valide, qui sera utile entre autres dans les domaines de la prévention et du traitement de l’épuisement professionnel.
