Examination of ethnic racial identity exploration and commitment in emerging adults: Group comparisons and specific features of multiracial identity.

Objective: Building on existing literature on ethnic/racial identity in emerging adulthood, we compared between-group differences for Multiracial and Monoracial participants and relevant within-group relationships for Multiracial participants. Participants: Participants were college students (n = 888; 67% women; Mage = 21.7; SD = 5.58) categorized into three groups: Monoracial White (61%), Multiracial (17%), and Monoracial Minoritized (22%). Methods: Measures included ethnic racial identity (ERI) exploration and commitment, discrimination, and features of Multiracial identity. The survey was sent through campus email and completed electronically. Results: Monoracial Minoritized participants reported higher discrimination and ERI commitment and exploration than Multiracial and Monoracial White participants. Multiracial participants reported higher ERI exploration and discrimination than Monoracial White participants. Multiracial participants' ERI exploration and racial conflict explained ERI commitment in regression models. Conclusions: Multiracial individuals should be researched and intervened with differentially from other racial groups, with variables specific to their unique experiences.

Cardiovascular effects of brief mindfulness meditation among perfectionists experiencing failure.

Research links perfectionism, the tendency to hold and pursue unrealistically high standards, to negative mental health outcomes such as eating disorders, anxiety, and depression. Previous research used high frequency heart rate variability (HF-HRV) to measure recovery from stress during a mindfulness meditation in perfectionistic university students and found that only nonperfectionists demonstrated HF-HRV recovery from stress, suggesting that mindfulness was not effective for perfectionists. However, the mindfulness meditation did not incorporate a nonjudgment element, which may be a key component for perfectionists. In the current study, we examined whether mindfulness with a focus on nonjudgment helps university student perfectionists (n = 120) recover from failure (measured by heart rate (HR), HF-HRV, pNN50). Students were randomly assigned to one of four meditation groups: nonjudgment mindfulness, general mindfulness (i.e., attentional awareness without a nonjudgment component), progressive muscle relaxation, and nothing. Cardiac data were recorded during a 5-min baseline, failure task, and 10-min meditation session. HR results suggest that both mindfulness conditions and "nothing" encouraged cardiovascular recovery, but that the mindfulness conditions showed even further recovery during the last five minutes of the meditations. HF-HRV results indicated that participants in the nonjudgment mindfulness condition had marginally higher HF-HRV during the last five minutes of the meditation than at baseline, while participants in the other conditions did not. Therefore, mindfulness with a focus on nonjudgment of emotions may be especially important to help perfectionists improve HF-HRV after failure.

The mindful attention and awareness scale is associated with lower levels of high-frequency heart rate variability in a laboratory context.

Trait mindfulness has been associated with well-being. A key component of trait mindfulness is intentional attention and awareness which is most commonly measured by the Mindful Attention and Awareness Scale (MAAS). This study investigated the relationship between the MAAS and cardiovascular (HF-HRV, heart rate) reactivity to two laboratory stressors that evoked different patterns of change in heart rate (HR). One stressor (viewing a video of a surgery) evoked HR deceleration while the other stressor (mental arithmetic) evoked HR acceleration. Undergraduate students completed the MAAS and were then exposed to the two stressors while ECG (electrocardiography) was recorded. Findings support the reliability of the stressors to induce expected differential cardiovascular responses and explicate the role of parasympathetic activation. Further, a main effect for MAAS was observed indicating that across laboratory conditions, persons scoring higher on the MAAS had lower HF-HRV relative to persons scoring lower on the MAAS. These findings suggest that higher levels of intentional attention and awareness in a laboratory context might promote parasympathetic withdrawal because these participants were more vigilant, experienced higher cognitive load, and detected more threat cues. Implications for the MAAS and cardiovascular responses to stress are discussed.
