In three studies we examined whether four social identity characteristics (gender, race, age, and socioeconomic status) affect perceived risk of disorder development for eating and mood relevant behaviors. Women and girls are at greater risk of developing an eating disorder than men and boys. However, because the race of Black women and girls does not fit the prototypical image of a person with an eating disorder (ED), we hypothesized ED-related behaviors would be perceived as less concerning for them. Study 1 demonstrated robust stereotypes along all four identity dimensions (gender, race, age, and socioeconomic status) for perceived ED prevalence, and weaker stereotypes for depressive and anxiety disorders. In Study 2, identical ED-related behaviors were interpreted as riskier and less healthy when performed by a female or White target, relative to a male or Black target. Identity dimensions did not affect risk judgments for mood disorder behaviors. Study 3 replicated and extended these results. These findings suggest Black women and girls are at a disadvantage in the early identification of risk factors associated with ED development. This work responds to the call for culturally sensitive research on the effects of diverse identities on detecting and addressing body image problems and eating disorders.

The COVID-19 pandemic has highlighted loneliness as a major risk factor for mental health difficulties among parents. Shared musical experiences may be an effective way to create social bonds. We adapted Carnegie Hall’s Lullaby Project to a remote format. Parents experiencing loneliness were enrolled in the study ( N = 40) and completed assessments at pre-intervention, post-intervention, and 1-month follow-up. Participation was associated with significant improvement in self-reported loneliness, self-reported sense of belonging, implicit sense of belonging, self-reported depression, and self-reported anxiety. However, the difference between implicit belonging and rejection did not significantly change over time, and there was no evidence for change in self-reported parent–child connection. In contrast to the quantitative findings, the qualitative responses suggested that participants experienced an enhancement in parent–child connection following intervention completion. The findings highlight the potential for remote administration of music programs to address isolation and loneliness.

Objective: Digital delivery of mindfulness-based cognitive therapy through the Mindful Mood Balance (MMB) program is clinically effective (Segal et al., 2020); however, the mechanisms through which this program delivers its benefits have not been established. Method: This study investigates the differential impact of the MMB program paired with usual depression care (UDC) compared to UDC alone on the putative targets of self-reported mindfulness, decentering, and rumination and the extent to which change in these targets mediates subsequent depressive relapse among a sample of predominantly White, female participants, with residual depressive symptoms. Results: The MMB program relative to UDC was associated with a significantly greater rate of change in decentering (t = 4.94, p < .0001, d = 0.46), mindfulness (t = 6.04, p < .0001, d = 0.56), and rumination (t = 3.82, p < .0001, d = 0.36). Subsequent depressive relapse also was mediated by prior change in these putative targets, with a significant natural indirect effect for decentering, χ2(1) = 7.25, p < .008, OR = 0.57; mindfulness, χ2(1) = 9.99, p < .002, OR = 0.50; and rumination, χ2(1) = 12.95, p < .001, OR = 0.35. Conclusions: These findings suggest the mechanisms of MMB are consistent with the conceptual model for mindfulness-based cognitive therapy and depressive relapse risk and that such processes can be modified through digital delivery.

Objective: Clinical studies of depression have historically excluded participants with suicidal ideation. Research participant safety protocols are critical to allow for the much-needed study of suicide risk. This report summarizes participant feedback about the safety protocol used in a national, remote study of perinatal women with suicidal ideation. Methods: Upon completion of the study, participants who had triggered the suicidality safety protocol during the study were invited to complete a brief survey with questions about their experiences with the protocol. The survey included 4 Likert-scale questions and 1 open text question where participants could provide feedback, suggestions, and comments to the research team. Participant feedback survey data were collected between October 2021 and April 2022, and this research was funded by the National Institute of Mental Health. Results: Of the 45 participants enrolled in the UPWARD-S study, 16 triggered the safety protocol. All eligible participants (N = 16) completed the survey. Among respondents, most were at least neutral to very comfortable with the call from the study psychiatrist (75% [n = 12]) and reported that the call had a "positive impact" on their well-being (69% [n = 11]). After the call with the study psychiatrist, 50% of participants (n = 8) reported that they increased engagement with treatment for depression, and the other 50% reported no change in treatment. We also report on themes from the qualitative feedback regarding suggestions of how to modify or improve the safety protocol. Conclusions: Learning from the experiences of research participants will provide unique insight into satisfaction with, and impact of, the implemented suicidality safety protocol. Findings from this study could inform the refinement and implementation of safety protocols used in depression studies as well as future research on the impact of such protocols.

... Planning and monitoring processes were not reported by learners during lab lessons, and substantial structure is provided to learners to alleviate the need to undertake such processes within lessons. To observe engagement in planning and monitoring activities, courses with different designs could be studied, and intentional co-design with instructors could be undertaken (Potvin et al., 2024). Codesign can provide opportunities to develop materials that encourage learners to engage more fully in self-regulated learning, but less external regulation during planning and evaluation phases, as high structure designs that impose constraints upon learners that approximate instances of external regulation and co-regulation (Hadwin, Järvelä, & Miller, 2011) are authentic to higher education given their prevalence but prevent observation of all SRL processes. ...

... Although some commonly used meta-analytic methods (e.g., weighting study-level effect size estimates by the inverse of their variance, using trim-and-fill analyses to estimate the impact of publication bias) can address some of the limitations of small sample studies particularly when sufficient primary studies are included, meta-analytic inferences based on such data are not immune from small sample biases and may therefore lead to erroneous conclusions (Lin, 2018;Simonsohn et al., 2022). While a couple of well-powered studies on mediators in MBIs have been conducted (e.g., Dimidjian et al., 2023), the field of MBI research has produced little strong evidence of statistical mediation and as a consequence, a dearth of knowledge to advance research toward a causal understanding of MBI effects. ...

... From the normative perspective of 'democratizing technology', the depression forums can be 'reinvented' in an emancipatory manner (Feenberg & Friesen, 2012). Several examples of similar inventions can be mentioned: an online mindfulness-based logotherapy programme for adolescents (Maria Michael & Reyes, 2023); a web-based mindfulness programme for new and expectant mothers (Metcalf et al., 2023) or a tele-behavioural health training (Felker et al., 2023) -these are just few recent ones. The online depression forums' untapped potential can be revealed from their perspective: by understanding the expansive medicalization and psychologization discourses, the chance for countering the misinterpretation of social suffering as a mere psychopathology increases. ...

... Heightened stress and psychopathology during pregnancy, in turn, are associated with negative consequences for parent and infant health and well-being during the postpartum period [8,9]. In addition to being a period of vulnerability for psychopathology, pregnancy simultaneously offers a critical opportunity for intervention [10,11]. Thus, early identification of parental internalizing problems, accompanied by evidence-based psychological interventions, is of particular importance for promoting individual and family well-being across this high-risk period. ...
