The impact of psoriasis on an individual's emotional and social well-being goes beyond skin symptoms of the disease. Data suggests patients with severe psoriasis experience a greater prevalence of depressive symptoms, mood disturbances, anxiety and even suicidal ideation. Given the nature of the disease and the treatment failures which are required before a patient commences a biologic therapy such as adalimumab, the patient's mental health at initiation of biologics is an important consideration for clinicians. This study seeks to explore if adalimumab treatment of psoriasis leads to a positive impact on psychosocial factors and disease-related quality of life.
This was a multi-center, prospective, post-marketing observational study of participants with severe chronic plaque psoriasis who began adalimumab therapy in the United Kingdom. Although 153 participants enrolled in the study, data was only analyzed on 143 individuals and there were no interventions or changes to participant management for the study. Prior to initiating adalimumab therapy (baseline), the Dermatology Life Quality Index (DLQI), Self-Administered Psoriasis Area Severity Index (SAPASI), Hospital Anxiety and Depression Scale (HADS), Cutaneous Body Image (CBI) scale, Short Form 12 (SF-12) Health Survey, Female Sexual Function Index (FSFI) (female participants) and International Index of Erectile Function (IIEF) (male participants) questionnaires were completed by participants and at 4 weeks, 16 weeks and 6 months following initiation.

Dermatology Life Quality Index (DLQI) Scores
The Dermatology Life Quality Index (DLQI) was a participant-reported questionnaire used to measure the health-related quality of life (QOL) of adults suffering from a skin disease. Scores ranged from 0-30, a higher score indicating a greater impact on a participant's QOL. Data are reported as the mean DLQI score ± standard deviation.
Time frame: Baseline; 4 weeks, 16 weeks, and 6 months following adalimumab initiation
Mean Change in Dermatology Life Quality Index (DLQI) Scores From Baseline
The Dermatology Life Quality Index (DLQI) was a participant-reported questionnaire used to measure the health-related quality of life (QOL) of adults suffering from a skin disease. Scores ranged from 0-30, a higher score indicated a greater impact on a participant's QOL. "Responders" to adalimumab had a ≥5 point reduction in DLQI scores or DLQI score of 0. Data are reported as the mean DLQI score ± standard deviation.
Time frame: 4 weeks, 16 weeks, and 6 months following adalimumab initiation
Self-assessed Psoriasis Area and Severity Index (SAPASI) Scores
The Self-assessed Psoriasis Area and Severity Index (SAPASI) questionnaire was used to objectively measure the severity of a participant's psoriasis, taking into account the area of psoriasis legions on the body and the characteristics of these legions (redness, thickness, scaliness). Scores ranged from 0-72, a higher score indicated more severe psoriasis. Data are reported as the mean SAPASI score ± standard deviation.
Time frame: Baseline; 4 weeks, 16 weeks, and 6 months following adalimumab initiation
Mean Change in Self-assessed Psoriasis Area and Severity Index (SAPASI) Scores From Baseline
The Self-assessed Psoriasis Area and Severity Index (SAPASI) questionnaire was used to objectively measure the severity of a participant's psoriasis, taking into account the area of psoriasis legions on the body and the characteristics of these legions (redness, thickness, scaliness). Scores ranged from 0-72, a higher score indicated more severe psoriasis. Data are reported as the mean change in SAPASI score ± standard deviation.
Time frame: 4 weeks, 16 weeks, and 6 months after adalimumab initiation
Psoriasis Area and Severity Index (PASI) Scores
The Psoriasis Area and Severity Index (PASI) questionnaire was used by the clinical staff to measure the severity of a participant's psoriasis, taking into account the area of psoriasis legions on the body and the characteristics of these legions (redness, thickness, scaliness). Scores ranged from 0-72, a higher score indicated more severe psoriasis. Data are reported as the mean PASI score ± standard deviation.
Time frame: Baseline; 4 weeks, 16 weeks, and 6 months following adalimumab initiation

Time frame: 4 weeks, 16 weeks, and 6 months following adalimumab initiation
Hospital Anxiety and Depression Scale (HADS) Scores
The Hospital Anxiety and Depression Scale (HADS) was a patient-reported questionnaire used to assess the level of anxiety and depression in the setting of a hospital medical outpatient clinic. The anxiety and depression subscales each have a range from 0-21, higher scores indicated higher levels of anxiety and depression, respectively. Data are reported as the mean anxiety or depression score ± standard deviation.
Time frame: Baseline; 4 weeks, 16 weeks, and 6 months following adalimumab initiation

Cutaneous Body Image Scale (CBI) Scores
The Cutaneous Body Image (CBI) Scale was a participant-reported questionnaire used to measure a participant's satisfaction with their hair, nails, and skin. Scores range from 0-9, higher scores indicated a higher level of satisfaction. Data are reported as the mean CBI score ± standard deviation.
