Work Stress and Impact of Pruritus on Quality of Life

Study Overview
=================
Brief Summary
-----------------
Work stress and pruritus: imbalance of effort balance reward in patients with psoriasis.

Detailed Description
-----------------
Background. Stress increases the likelihood of psoriasis flare-up episodes and itching. Few studies have focused on work-related stress on such skin symptoms. Objective. To study the association between work-related stress, pruritus and quality of life among workers suffering from psoriasis. Methods. Investigators will conduct a monocentric non-interventional prospective study. Patients suffering from psoriasis will be recruited in both the Dermatology inpatient ward and outpatient clinic of Brest University Hospital . Included patients will be workers. Work-related stress will be assessed using the Effort-Reward Imbalance (ERI) model. The impact of pruritus on quality of life will be assessed with the Itchy Quality of Life (ItchyQoL) self-administered questionnaire. The collected data will include age, sex, body mass index, ordered medication to treat psoriasis, weekly working hours. The association between ERI and ItchyQoL scores will be studied using a univariate logistic regression.

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Pruritus' impact on quality of life | The Itchy Quality of Life questionnaire (ItchyQoL) assess the quality of life linked to pruritus. It is a 22-item questionnaire wich assess the frequency of pruritus'symptoms in the past seven days. The score is between 22 and 110. The higher the score, the greater the impact of pruritus. | time required to complete the self questionnaire estimated at approximately 5 min immediately after consultation with the dermatologist | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Occupational stress | The effort-reward imbalance questionnaire in 23-item for occupational stress. Six items make it possible to calculate the extrinsic efforts felt (score e) and eleven items assess the rewards perceived by the employee (score r). The ERI score is then calculated as follows: Ratio = (11 x e) / (6 x (66 - r)) (e: effort scale score, r: rewards scale score). A ratio greater than one indicates an imbalance in favor of efforts. The last six items make it possible to calculate the score for intrinsic efforts (over commitement). They relate to the inability to get away from work, impatience and disproportionate irritability. | time required to complete the self questionnaire estimated at approximately 5 min immediately after consultation with the dermatologist |
