Abstract: Background: Though cost perceptions are thought to be key motivational beliefs that can undermine academic engagement, little research has designed or tested interventions to reduce cost perceptions for students. Aims: We developed, implemented, and evaluated a weekly cost reduction intervention utilizing motivational regulation strategies to reduce cost. Sample: Participants were 449 undergraduate calculus students. Methods: Using a pre-registered randomized controlled trial, students were assigned to a cost reduction condition or control condition for 13 consecutive weeks. In the cost reduction condition, students reflected on a list of motivational regulation strategies and wrote about how they would use a specific strategy the following week. Results: The intervention significantly reduced weekly task effort cost, weekly emotional cost, final task effort cost, final loss of valued alternatives cost, and final emotional cost on average for all students. However, interaction analyses revealed that benefits were often limited to specific groups, aligning with tentative pre-registered hypotheses. Racially marginalized students in the intervention reported lower weekly emotional cost, higher weekly interest, lower final task effort cost, and lower final emotional cost, compared to racially marginalized students in the control condition; these effects did not appear among non-racially-marginalized students. Additionally, students with lower high school GPAs in the intervention reported higher STEM career intentions and only students with higher high school GPAs reported lower weekly outside effort cost compared to their counterparts in the control condition. Conclusions: The statistically significant effects demonstrate the potential of weekly cost reduction interventions for helping some students with their learning. © 2025 The Authors Mon, 01 Dec 2025 00:00:00 GMT https://scholarx.skku.edu/handle/2021.sw.skku/124796 2025-12-01T00:00:00Z https://scholarx.skku.edu/handle/2021.sw.skku/125968 Title: The Role of Motivational Regulation and Cost on Motivational Conflicts and Emotions Authors: Kim, Yeo-eun; Zepeda, Cristina D.; Martin, Rachel S.; Butler, Andrew C. Abstract: As students pursue multiple goals across the domains of their everyday lives, they inevitably experience motivational conflicts. They may feel like they would rather do something else or feel like they should be doing something else. The purpose of this study was to use an experience sampling method (ESM) to examine how students' real-time motivational conflict and emotional experiences differed across contexts. Fifty-seven undergraduate students provided 1,504 responses. Our findings revealed that: 1) motivational conflict experiences were prevalent in academic, social, and personal contexts; 2) motivational conflict and momentary emotions were dynamically intertwined; and 3) cost perceptions and motivational regulation can serve as potential person-level antecedents of motivational conflict experiences and momentary emotions. Our study highlights the importance of investigating in-situ motivational conflict and emotional experiences in both academic and nonacademic contexts.

Using latent transitional analysis, the research revealed evolving patterns of PTSD symptoms, depression, and anxiety, along with the changing and consistent impact of various predictors. The results indicated two subgroups (low symptom and high symptom) at T1, and three subgroups (low symptom, moderate symptom, and high symptom) at T2. Significant predictors of group membership at both T1 and T2 were gender, general fear of the COVID-19 situation, and avoidance coping. General fear of the COVID-19 situation significantly influenced group transitions. These findings provide insights into the nuanced influences on psychological distress during the global crisis, emphasising the need to address gender-specific concerns and general fear related to COVID-19 as significant factors influencing symptom levels and transitions over time. © 2025 Asian Association of Social Psychology and John Wiley & Sons Australia, Ltd.

The research was conducted in three stages: (1) literature review and school counselor interview on self-harm and suicidal risk factors in the adolescent population; (2) development of a list of risk factors (3) Delphi survey on counselor panel and adolescent panel. Three rounds of the Delphi questionnaire were conducted for each panel. Results discovered that there was consensus between the counselors and adolescents as well as counselor and adolescent exclusive risk factors. Both panels agreed on ‘psychiatric difficulties,’ ‘guilt,’ ‘perceived burdensomeness,’ ‘feeling worthlessness,’ ‘powerlessness,’ ‘hopelessness,’ ‘acquired capability for suicide,’ ‘positive expectations of death,’ ‘lack of meaning in life,’ ‘absence of alternatives to self-harm,’ ‘loneliness,’ ‘impulsivity,’ ‘exposure to problematic parenting,’ ‘family conflict,’ ‘domestic abuse,’ ‘experience of school violence’ ‘bullying or being out casted’, ‘loss of reliance’ and ‘economic hardship.’ Counselor panel exclusive consensus represented the importance of a broad range of risk factors, while adolescents suggested risk factors using expressions that specifically and delicately revealed internal experiences. The consented risk factors could enhance adolescent suicide prevention, as they were validated by the key stakeholders, the adolescents in crisis, and their counselors. © 2025 Wiley Periodicals LLC.
