Firstly, Juliet interviewed a sample of 17-year-old students using a structured interview method, where she asked them to state the length of time they spent on social media per day. Juliet then asked the same participants to complete a questionnaire to rate how happy they were with their appearance, with a score of 0 being ‘very unhappy’ and 10 being ‘very happy’. (a) Define what is meant by a ‘structured interview’.

(2002) conducted a natural experiment in Fiji to investigate the impact of television on eating behaviours. They assessed attitudes to eating in 1995, just as television was being introduced to the native population. They returned in 1998 to assess eating behaviours after three years of television exposure. 63 girls with a mean age of 17.3 years took part in 1995. A second sample of 65 girls with a mean age of 16.9 years took part in 1998. To score eating behaviours, the two samples of girls completed a standardised EAT-26 questionnaire. They also answered questions about television viewing. Their weight, height, and body mass index (BMI) were also recorded. Comparisons between 1995 and 1998 data indicated that, after exposure to western imagery on television, the reports of disordered eating such as self-induced vomiting to lose weight had increased. Evaluate the use of natural experiments to investigate human behaviour.
