A Self-determination Theory Perspective of Women's Body Image and Eating-related Concerns in Response to Media Portrayals of the Female Body
Bibliographic record
Abstract
Grounded in Self-Determination Theory (Deci & Ryan, 1985, 2000), the purpose of this thesis was to investigate the protective role of self-determined (i.e., autonomous motivation) relative to non self-determined motivation (i.e., controlled motivation) in response to various media portrayals of the female body. Findings from three laboratory experiments support these hypotheses. Women who felt less self-determined in their daily activities (Study 1 and Study 3) and in the regulation of their eating behaviors (Study 2), perceived more pressure from the media to be thin (Study 1), experienced more body dissatisfaction (Study 1 and Study 2), expressed greater concerns over the quantity of food in their diets (Study 1), and reported more negative affect (Study 2) following exposure to a video which exemplified the societal ―thin ideal‖ compared to a video which did not. They also generated more negative self-appraisals of their body‘s appearance and competence (Study 3), experienced more body shame (Study 3), and reported more introjected reasons for restricting their actual intake of chocolate (Study 3) following exposure to video which depicted the female body as an instrument of women‘s actions compared to one which depicted the female body as object (Study 3). Conversely, women who felt more self-determined in their daily activities (Study 1 and Study 3) expressed greater concerns over the quality of food in their diet (Study 1) and reported less vitality (Study 3) in response to media portrayals of women engaged in self-care (Study 1) and physical activities (Study 3). However, body dissatisfied women who felt more self-determined in the regulation of their eating behaviors (Study 2) formulated more intentions to monitor their food intake and eat fewer unhealthy foods (Study 2) after viewing a video of thin female models compared to no models. Together, these findings support a protective function for self-determined motivation and a potentiating function for non self-determined motivation.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
