This contemporary study is a key component of your Learning Theories and Development topic (Section 4.3.2). It provides critical real-world evidence for Social Learning Theory (SLT) by investigating how the introduction of television altered cultural body ideals and eating behaviours in a community previously unexposed to Western media.

What you'll learn

• The cultural context of Fiji before the introduction of television.
• How Becker et al. designed and conducted this natural experiment.
• Key quantitative and qualitative findings regarding EAT-26 scores and self-induced vomiting.
• How to evaluate the study using methodological, practical, and ethical criteria (AO3).

Prerequisites: Cultural Context and Social Learning

To understand the impact of Becker et al.’s research, you must first understand the cultural landscape of Fiji in the mid-1990s.

Traditionally, ethnic Fijian culture celebrated a robust and well-rounded body shape. A larger body was traditionally associated with:

• Health, strength, and physical fertility.
• Generosity and care from the community (reflecting that a person was well-fed and cherished by their family).
• A collective responsibility for feeding and nutrition.

Before 1995, there was virtually no clinical awareness of eating disorders, and dieting or body dissatisfaction were culturally alien concepts.

In 1995, broadcast television was introduced to the Nadroga province of Fiji. This created a unique opportunity for researchers to study the immediate, real-time effects of Western media exposure on a population that had never experienced it before.

Aim of the Study

Becker et al. (2002) aimed to investigate the impact of prolonged exposure to television on eating attitudes and behaviours among ethnic Fijian adolescent girls.

Specifically, they wanted to determine whether the introduction of media showcasing Western thin-ideal body shapes would lead to:

1. An increase in body dissatisfaction.
2. A rise in disordered eating behaviours (such as purging/self-induced vomiting).

Methodology & Procedure

This study is classified as a natural experiment (or a quasi-experiment) with a cross-sectional design comparing two separate, independent cohorts of adolescent girls.

The Sample

The participants were ethnic Fijian girls aged 15 to 19 from schools in the Nadroga district.

• 1995 Cohort: $n=63$ girls studied just as television was being introduced.
• 1998 Cohort: $n=65$ girls studied three years after television had been introduced.

The Procedure

The researchers used a mixed-methods approach to gather both quantitative (numerical) and qualitative (descriptive) data.

1. EAT-26 Questionnaire: All participants completed the standard Eating Attitudes Test (EAT-26), a clinical survey measuring symptoms of eating disorders. A score above 20 indicates a high risk of disordered eating.
2. Semi-structured Interviews: Participants who indicated disordered eating behaviours (or a subset of girls) were interviewed about their attitudes toward body image, beauty ideals, and television.
3. Physical Measurements: The height and weight of each participant were measured to calculate their Body Mass Index (BMI), ensuring any change in eating habits was not simply due to physical weight changes.
4. TV Ownership Survey: Participants were asked about whether they had a television in their household and how often they watched it.

Key Findings

The results of Becker et al. (2002) revealed a dramatic shift in both eating behaviours and cultural attitudes over the three-year period.

Quantitative Findings

• EAT-26 Scores: The percentage of girls scoring above 20 on the EAT-26 (indicating serious risk of disordered eating) rose from 12.7% in 1995 to 29.2% in 1998. This difference was statistically significant.
• Purging (Self-Induced Vomiting): In 1995, 0% of the girls reported purging to control their weight. By 1998, this figure had risen sharply to 11.3%.
• Television Ownership: Household TV ownership increased from 41.4% in 1995 to 70.8% in 1998.
• Body Mass Index (BMI): There was no significant difference in average BMI between the 1995 cohort (mean = 24.9) and the 1998 cohort (mean = 24.5). This indicates that changes in eating attitudes were psychological rather than reflecting changes in actual physical weight distribution.

Qualitative Findings

The semi-structured interviews in 1998 revealed a direct link between media consumption and body image ideals:

• Many girls expressed a desire to reshape their bodies to look more like the Western television characters they watched on shows like Melrose Place and Beverly Hills 90210.
• Participants remarked that slimness was associated with modernization, career success, and being "desirable."
• The girls reported experiencing conflict between traditional Fijian values (which encouraged eating well) and the new cultural pressure to be thin.

Conclusions

Becker et al. concluded that prolonged exposure to media featuring thin-ideal roles models can rapidly undermine traditional body ideals and lead to disordered eating behaviours, even in a culture with historically strong protections against body dissatisfaction.

This study provides compelling evidence for Social Learning Theory, suggesting that the girls observed thin characters receiving praise, attention, and high social status (vicarious reinforcement) and imitated these behaviours (purging, dieting) to achieve the same rewards.

Evaluation (AO3)

When evaluating a study in A-Level Psychology, structure your points using the G-R-A-V-E framework.

Strengths

• High Ecological Validity (V): Because this was a natural experiment, the independent variable (introduction of TV) occurred naturally. The girls remained in their everyday environments, meaning their media exposure and behavioural reactions were entirely authentic.
• Mixed-Methods Design (V/R): By combining quantitative questionnaires (EAT-26) with qualitative interviews, Becker et al. achieved both objective, standardized measurements and deep, rich insights into the girls' subjective thoughts and motivations.
• Practical Application (A): The findings have major real-world applications. They highlight the danger of exporting Western media to vulnerable cultures, prompting calls for more diverse body sizes in global broadcasting and the development of targeted eating-disorder prevention programs.

Weaknesses

• Issues with Generalisability (G): The sample consisted exclusively of adolescent ethnic Fijian girls. The findings may not generalize to:
  • Male adolescents, who may react differently to media exposure.
  • Individuals in older or younger age brackets.
  • Western cultures that have already developed complex psychological coping mechanisms over decades of media exposure.
• Lack of Direct Control (V): Because this was a natural experiment, the researchers could not control for extraneous variables. For instance, we cannot be certain that the increase in eating disorders wasn't influenced by other elements of Westernization, such as changes in dietary options, fashion trends, or economic developments occurring between 1995 and 1998.
• Ethical Considerations (E): Although the researchers did not introduce television themselves (avoiding direct harm), they uncovered high rates of self-induced vomiting and eating distress among vulnerable teenagers. Under modern BPS guidelines, researchers have a duty to protect participants from harm and ensure that those showing severe clinical symptoms are offered appropriate psychiatric support.
