Previous research has demonstrated that interpersonal aspects of perfectionism are related to increased trait social anxiety. The present research examined if trait mindfulness was a mediator of that relationship in students. Participants were undergraduate-(n = 227) and graduate-level (n = 215) students enrolled in Canadian institutions. Students completed a series of measures of perfectionistic self-presentation, trait perfectionism, social interaction anxiety, social phobia, and trait mindfulness. We found a positive association between nondisplay and nondisclosure of imperfections with social interaction anxiety, as well as a positive association between socially prescribed perfectionism and nondisplay of imperfections with social phobia. Level of study did not moderate the associations between components of perfectionism and social anxiety. Trait mindfulness mediated the associations between interpersonal components of perfectionism and two aspects of trait social anxiety (i.e., social interaction anxiety and social phobia). Our results have implications for the understanding of the mechanisms through which interpersonal perfectionism is related to social anxiety. While more research is needed, future interventions could implement mindfulnessbased strategies for students experiencing distress from perfectionistic tendencies and social anxiety. Public Significance StatementPerfectionism has been suggested to elicit social disconnection that predisposes one to various forms of distress such as social anxiety. Trait mindfulness, or lack thereof, was conceptualized as a form of disconnection and was found to explain the relationship that interpersonal forms of perfectionism had with social interaction anxiety and social phobia.

Policing is a high-stress occupation, and officers frequently experience high rates of occupational (i.e., operational and organizational) stressors that can result in mental health symptoms such as stress, anxiety, and depression. Trait mindfulness facets and self-compassion have been consistently associated with lower levels of stress, anxiety, and depression; yet, they have been understudied in police officers. The objective of the present study is to examine whether trait mindfulness facets (i.e., observing, describing, acting with awareness, nonjudging, and nonreactivity) and self-compassion moderate the relationship between operational and organizational stressors with stress, anxiety, and depression symptoms in a sample of Canadian police officers. Canadian police officers (n = 130) completed online self-report measures assessing their levels of operational and organizational stressors, trait mindfulness and self-compassion, and stress, anxiety, and depression symptoms. Moderation analyses indicated that the nonjudging facet of mindfulness moderated the relationship between operational and organizational stressors with anxiety symptoms, such that the relationship between operational and organizational stressors with anxiety was not statistically significant for police officers higher in nonjudging. Implications for future research are discussed. Public Significance StatementThe present study suggests that the nonjudging facet of mindfulness may play a role in protecting police officers under operational and organizational stress from experiencing anxiety symptoms. Future research using more rigorous designs should continue to inform this growing area.

Forensic inpatients (i. e., individuals found not responsible for a criminal offense on account of mental illness) represent an often marginalized and difficult-to-treat population. This has led to the need for research exploring the effectiveness of novel interventions. A Canadian forensic hospital has developed an 8-weeks mindfulness and yoga training program (MTP). This pilot study examined the potential effects of this program on patients' mindfulness, stress, and use of cognitive and emotion regulation strategies. A sample of 13 forensic inpatients (male = 92%) participating in the MTP program completed self-report measures assessing dispositional mindfulness, perceived stress, and use of cognitive emotion regulation strategies at baseline, post-intervention, and a 3-months follow-up. Repeated measure ANOVAs found a significant increase in the describe facet of mindfulness (p = 0.03) with a large effect size (ηp2 = 0.26) and a significant decrease in stress (p = 0.003) with a large effect size (ηp2 = 0.39). Pairwise comparisons revealed medium to large significant changes between baseline and post-intervention for both the describe facet (p = 0.03, Hedge's g = 0.55) and stress (p = 0.003, Hedge's g = 0.70). However, comparisons were insignificant between baseline and follow-up. No significant main effects were found on the use of cognitive emotion regulation strategies. This pilot study offers preliminary support for the use of the MTP as an adjunctive therapy in forensic inpatient treatment. Further investigation is needed into the long-term impacts of this training.

According to the Center for Disease Control and Prevention, over 14% of the US population practice mindfulness meditation. The effects of mindfulness training on physical and mental health have been consistently documented, but its effects on interpersonal relationships are not yet fully understood or investigated. Interpersonal relationships play a crucial role in the wellbeing of individuals and society, and therefore, warrants further study. The aim of this paper is to present a tri-process theoretical model of interpersonal mindfulness and a study protocol to validate the proposed model. Specifically, according to the proposed model, mindfulness meditation training increases the self-awareness, self-regulation, and prosociality of those receiving the training, which ameliorates the quality of interpersonal interactions and the socioemotional support provided to other individuals. Finally, better socioemotional support increases the support receiver’s ability to regulate their emotions. Using a multiphasic longitudinal design involving 640 participants randomized into 480 dyads, the proposed protocol aims to validate the tri-process model and to investigate its mechanisms of actions. The proposed study has important theoretical and social implications and will allow devising new and more effective interpersonal mindfulness programs with applications in multiple fields.
