| Abstract |
Approximately 20% of children and adults avoid certain foods because of perceived food intolerance. Valid and reliable health-related quality of life instruments are needed to measure changes following clinical, therapeutic or policy interventions. However, there are no disease-specific quality of life instruments for adults with food intolerances. To develop the Food Intolerance Quality of Life Questionnaire FIQLQ. Then to conduct psychometric validation including reliability and construct validity. We adapted the existing Food Allergy Quality of Life questionnaire (FAQLQ) for interviews with 14 adults with food intolerance. For preliminary psychometric validation, 229 adults with food intolerances completed the online electronic version of FIQLQ. The resultant FIQLQ had 18 items which loaded onto 3 subscales-Emotional Impact, Social and Dietary Restrictions, Reactions and Avoidance. Each subscale had excellent internal consistency reliability (Cronbach's α 0.81-0.94). Content, convergent and construct validity was supported by significant correlations of FIQLQ subscale scores with hypothesised variables including age, numbers of symptoms and level of stress experienced due to intolerance. The FIQLQ has good reliability, construct validity and internal consistency. It is short and easy to use, providing a good tool for evaluating quality of life in the clinical research setting and to inform health and regulatory policies. |

Attention Score in Context
This research output has an Altmetric Attention Score of 2. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 28 January 2020.
All research outputs
#13,882,258
of 23,008,860 outputs
Outputs from Quality of Life Research
#1,445
of 2,915 outputs
Outputs of similar age
#223,100
of 437,882 outputs
Outputs of similar age from Quality of Life Research
#20
of 60 outputs
Altmetric has tracked 23,008,860 research outputs across all sources so far. This one is in the 38th percentile – i.e., 38% of other outputs scored the same or lower than it.
So far Altmetric has tracked 2,915 research outputs from this source. They receive a mean Attention Score of 4.6. This one is in the 49th percentile – i.e., 49% of its peers scored the same or lower than it.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 437,882 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 47th percentile – i.e., 47% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 60 others from the same source and published within six weeks on either side of this one. This one has gotten more attention than average, scoring higher than 66% of its contemporaries.
