Outcome Measures

Primary Outcomes (4)

  • self-assessed Simplified Psoriasis Index

    The self-assessed Simplified Psoriasis Index measures psoriasis severity as a joint score of 3 categories. Severity; a 3-point scale will measure the severity of skins lesions on 10 body parts. 0=minimal, +/-=noticeable. + =extensive. A 5-point scale ranging from 0=clear to 5=intensely inflamed skin will measure the overall state of psoriasis. Psychosocial; a 10 point scale ranging from 0=not at all to 10=very much will indicate the extent to which psoriasis is affecting day-to-day life. Intervention; participants will need to indicate each psoriasis treatment that is being received. 1 point per treatment. The sa-PSI will generate a total score out of 70. The higher the score, the greater the severity of psoriasis.

    Baseline

  • The Dermatology Life Quality Index (DLQI)

    This index measures the impact of psoriasis on day-to-day routines as well as on psychological and social fronts. Responses to questions are scored as follows: very much (3 points), a lot (2 points), a little (1 point), not at all/not relevant (0 points). The DLQI provides a score between 0-30. The score range is interpreted as follows: 0-1 points = no effect at all on the participants life, 2-5 points = small effect on participant's life, 6-10 points = moderate effect on participant's life, 11-20 = very large effect on participant's life and 21-30 = extremely large effect on participant's life.

    Baseline

  • Diet

    The Twins United Kingdom (TwinsUK) modified European Prospective Investigation into Cancer Food Frequency Questionnaire (EPIC FFQ) will assess dietary intake. This FFQ will provide an overview of the consumption of 131- food items over the past 12 months. Each food item will be rated on a 9 point scale as follows: Never or less than once a month, 1-3 times per month, Once a week, 2-4 per week, 5-6 per week, Once a day, 2-3 per day, 4-5 per day and 6+ per day.

    Baseline

  • Diet

    Nutrient consumption will be examined using the Intake24 (https://intake24.co.uk/). This is dietary assessment tool in which participants will record their food intake over the past 24 hours. The results obtained from the Intake24 will provide a detailed breakdown of the total calories, macronutrients and micronutrients consumed.
