Validity study for the stigmatization experience in atopic dermatitis and psoriatic patients

Area of Science:

• Dermatology
• Psychology
• Psychometrics

Background:

• Atopic dermatitis and psoriasis significantly impact patients' lives, often leading to feelings of stigmatization.
• The Questionnaire on Experience with Skin Complaints (QES) was developed to assess these stigmatization experiences.

Purpose of the Study:

• To evaluate the psychometric properties, particularly the validity, of the QES.
• To provide further insights into the stigmatization experiences of patients with atopic dermatitis and psoriasis.

Main Methods:

• Psychometric evaluation of the QES.
• Analysis of three patient groups: 76 with atopic dermatitis and 298 with psoriasis (81 + 217).
• Comparison of stigmatization experiences across different affected body regions and coping styles.

Main Results:

• The QES demonstrated validity and reliability for assessing stigmatization in patients with atopic dermatitis and psoriasis.
• The genital region was identified as a particularly relevant area for stigmatization.
• Stigmatization, as measured by QES, was largely independent of coping styles, except for 'Rumination'.

Conclusions:

• The Questionnaire on Experience with Skin Complaints (QES) is a valid and reliable instrument for studying patient stigmatization in atopic dermatitis and psoriasis.
• Understanding the specific triggers, like affected body regions, can inform patient support.
• The QES aids in quantifying the psychological burden of these chronic skin conditions.
