Psychometric Properties of the Farsi version of the Fear of Food Measure for Adolescents (F-FOFM-A) in Iran
This study validates the Farsi version of the Fear of Food Measure for Adolescents (F-FOFM-A) in a large Iranian sample, confirming its reliability, three-factor structure, and strong validity for assessing fear of food and predicting eating disorder symptoms across different demographic groups.

Imagine your mind has a "fear alarm" that goes off when you think about eating certain foods. For some people, this alarm is so loud and constant that it stops them from enjoying meals, restricts what they eat, or makes them anxious about eating in front of others. This is what researchers call the "Fear of Food."
This paper is about building and testing a new "thermometer" to measure how hot that fear alarm is ringing, specifically for teenagers in Iran.
Here is the story of how they did it, explained simply:
1. The Problem: A Missing Tool
In the West, scientists already had a good thermometer (called the FOFM-A) to measure this fear. But they didn't have one for Iran. Since food plays a huge role in Iranian culture (think big family gatherings, hospitality, and social meals), understanding if teenagers there are afraid of food is important. The researchers wanted to translate the Western thermometer into Farsi and make sure it worked just as well for Iranian kids as it does for American ones.
2. The Experiment: Testing the Thermometer
The team gathered 1,243 Iranian teenagers (ages 10 to 19) from 24 different schools. It was a big group, with about three-quarters being girls.
They asked these teens to fill out a survey about their fear of food. But they didn't stop there. To make sure the thermometer was actually measuring "fear" and not just general sadness or worry, they also asked about:
- Eating disorder symptoms (like restricting food or worrying about weight).
- Depression.
- General worry.
- Their height and weight (to calculate a health score called zBMI).
3. The Results: Does the Thermometer Work?
The researchers ran the numbers through a statistical "stress test" (called Confirmatory Factor Analysis) to see if the thermometer held up. Here is what they found:
A. The Three-Part Structure (The Shape of the Thermometer)
The original thermometer had three distinct parts, and the Iranian version kept this shape perfectly:
- Anxiety About Eating: The general worry or tension you feel just thinking about eating.
- Food Anxiety Rules: The strict "rules" you make for yourself to stay safe (e.g., "I can only eat this specific food," or "I must eat at this exact time").
- Social Eating Anxiety: The fear of eating in front of other people.
B. The "Fairness" Test (Measurement Invariance)
They wanted to know: Does this thermometer work the same way for a boy as it does for a girl? For a 10-year-old as it does for a 19-year-old? For a heavier teen as it does for a lighter teen?
The answer was YES. The thermometer measured fear consistently across all these groups. This means if a girl scores higher than a boy, it's a real difference in fear, not a glitch in the test.
C. Who Has the Loudest Alarm?
Once they confirmed the test was fair, they looked at the scores:
- Girls reported higher fear than boys.
- Younger teens (10–14) reported higher fear than older teens (15–19).
- Teens with higher weight reported higher fear than those with average weight.
D. Is it Measuring the Right Thing? (Validity)
- Convergent Validity: The fear scores were strongly linked to eating disorder symptoms. This makes sense; if you are terrified of food, you are likely to have eating issues.
- Discriminant Validity: The fear scores were linked to depression and worry, but much more strongly linked to eating issues. This proves the thermometer is specifically measuring food fear, not just general sadness.
- Incremental Validity: Even after accounting for age, gender, weight, depression, and worry, the fear of food scores still predicted eating disorder symptoms. It's like saying, "Even if we know how sad and worried a teen is, knowing their fear of food tells us even more about their eating problems."
4. The Conclusion
The researchers successfully translated the "Fear of Food" thermometer into Farsi and proved it is a reliable and accurate tool for Iranian teenagers.
Think of it like this: Before this study, doctors in Iran trying to understand a teen's fear of food were using a map from a different country. Now, they have a map drawn specifically for the terrain of Iran. This tool can help researchers understand how common this fear is and how it connects to eating problems in Iranian youth, without needing to guess or use a tool that might not fit the culture.
In short: The study built a new, culturally accurate ruler for measuring "fear of food" in Iran, proved it measures what it's supposed to, and found that girls, younger kids, and heavier teens tend to have the highest levels of this fear.
