Machine learning uncovers the most robust self-report predictors of relationship quality across 43 longitudinal couples studies

Given the powerful implications of relationship quality for health and well-being, a central mission of relationship science is explaining why some romantic relationships thrive more than others. This large-scale project used machine learning (i.e., Random Forests) to 1) quantify the extent to which relationship quality is predictable and 2) identify which constructs reliably predict relationship quality. Across 43 dyadic longitudinal datasets from 29 laboratories, the top relationship-specific predictors of relationship quality were perceived-partner commitment, appreciation, sexual satisfaction, perceived-partner satisfaction, and conflict. The top individual-difference predictors were life satisfaction, negative affect, depression, attachment avoidance, and attachment anxiety. Overall, relationship-specific variables predicted up to 45% of variance at baseline, and up to 18% of variance at the end of each study. Individual differences also performed well (21% and 12%, respectively). Actor-reported variables (i.e., own relationship-specific and individual-difference variables) predicted two to four times more variance than partner-reported variables (i.e., the partner’s ratings on those variables). Importantly, individual differences and partner reports had no predictive effects beyond actor-reported relationship-specific variables alone. These findings imply that the sum of all individual differences and partner experiences exert their influence on relationship quality via a person’s own relationship-specific experiences, and effects due to moderation by individual differences and moderation by partner-reports may be quite small. Finally, relationship-quality change (i.e., increases or decreases in relationship quality over the course of a study) was largely unpredictable from any combination of self-report variables. This collective effort should guide future models of relationships

The Relationship Between Service Learning And Medical Student Academic And Professional Outcomes

BACKGROUND: Little is known about the relationship between medical student participation in service and performance outcomes. PURPOSE: To examine relationships between involvement in required service learning and measures of academic and professional achievement and specialty choice. METHODS: Using preexisting, self-reported data for Tulane University School of Medicine\u27s class of 2004, we categorized students as low, moderate, or high on commitment and involvement in service learning (CISL) and compared to multiple outcomes: class rank; election to the Alpha Omega Alpha (AOA) Honor Society; election to the Gold Humanism in Medicine Honor Society; total percent scores on 2 multistation, structured, clinical examinations; and specialty choice per 2004 residency match results. RESULTS: Service learning involvement was related to class rank. There was a marginal relationship between CISL and election to AOA but no association with election to the Gold Humanism in Medicine Honor Society, Year 2 or 3 clinical skills examination results, or specialty choice. CONCLUSIONS: High participation in service learning and service learning leadership identify a group of students less likely to be in the top quartile of their class yet who are making important contributions to the community and profession

A New Approach to Bridging Content Gaps in the Clinical Curriculum

BACKGROUND: In 2004-05 Tulane University School of Medicine implemented a longitudinal Interdisciplinary Seminar Series composed of small-group interactive exercises to address topics that are often overlooked during the clinical education of medical students. The series utilizes five adult learning principles. METHODS: Each of 13 seminars is offered at a fixed time slot, repeated two to six times per year. Students are required to attend a minimum of five seminars, of their choice, during years three and four. Students access an online pre-enrollment system that maximizes learning opportunities by limiting the number of participants. Seminars emphasize active learning with small-group problem-solving exercises and multiple interactive techniques. Clinical vignettes, standardized patients, journal articles, and case-based learning are among the learning methods. RESULTS: Seminar evaluations showed strong support in program content and effectiveness (mean = 4.47 on a five-point scale), facilitators (4.63), and learning opportunities (4.51). Additionally, students strongly endorsed individual seminars to classmates (4.47). Twelve of 13 (92%) seminars received scores higher than 4.0 for program content and effectiveness, facilitators and learning opportunities. CONCLUSIONS: The Interdisciplinary Seminar Series has been a valuable addition to the Tulane clinical curriculum. Students report that the success of the series is due to: (a) their ability to select seminars based on their individualized interests and needs; and (b) faculty development of student-centered seminars with active learning opportunities. This Seminar Series differs from interclerkship initiatives at other medical schools where topics are offered less frequently and to a class as a whole. Tulane\u27s program is a longitudinal intervention with multiple opportunities for student participation during their clinical education. Seminars are repeated to allow greater flexibility in student scheduling. Seminar discussions are rich in content since attendees include both third- and fourth-year students with variable levels of clinical skills and experiences
