Psoriasis is a chronic inflammatory disease associated with significant impairment in quality of life. Although quality of life in patients with psoriasis has been widely studied, there is little evidence regarding the impact of psoriasis on major life-changing decisions (MLCD). The aims of this study are to describe the impact of psoriasis on MLCD and to explore the potential clinical factors associated with MLCD. This cross-sectional study included 113 patients with psoriasis, regardless of disease severity, duration, or current treatment. The impact of the disease on different MLCD, including those related to professional career, decision of having children, choice of clothing, and leisure activities, was explored using Likert scales. Mean age was 51 years old and female to male ratio was 1.08 (54/50). The mean Psoriasis Area Severity Index was 3.75, and 30% (35/113) of the patients had psoriatic arthropathy. The most affected MLCD were career choice (median (interquartile range) score 3 (2–4)), social relationships (2 (1–3)), choice of clothing (2 (1–3)), job performance, absenteeism, and choice of holiday destination (1 (0–2)). Female sex, early age of onset and psoriatic arthropathy were associated with a greater impact of the disease on MLCD (p < 0.05). The results showed that a range of MLCD are affected in patients with psoriasis, such as career choice, job performance, absenteeism, or choice of clothing. Female sex, psoriatic arthritis and early age of onset are factors associated with a greater impact on MLCD. In order to limit the long-term negative effects of psoriasis on patients, special attention should be paid to detection of psoriatic arthritis, and to patients with early disease onset.
Key words: psoriasis; quality of life; life-changing decisions.
Psoriasis is a chronic skin disease associated with quality-of-life impairment. This study assessed the impact of psoriasis on vital decisions regarding decisive subjects in patients’ lives (termed “major life-changing decisions”). The results show that that psoriasis frequently influences career choice, social relationships, choice of clothing, and job performance. Moreover, female patients, those with an early age of onset of psoriasis and psoriatic arthropathy are more likely to have a greater negative impact of the disease. Special attention should be paid to these groups of patients in order to limit the long-term negative effects of psoriasis.

Psoriasis is a common chronic inflammatory skin and multisystemic disease (1), which may involve joints and could be associated with a variety of comorbidities (2), such as psoriatic arthritis (2), metabolic syndrome and obesity (3), cardiovascular disease (4), and psychological disorders (5, 6). Moreover, psoriasis is related to impairment in the quality of life of both patients and their cohabitants (7, 8).
As previously described by Bhatti et al. (9), chronic disease may have an impact, not only on current quality of life, but also in the long-term on critical life decisions, such as the decision to have children, get divorced, choice of job or place to live. These critical life decisions are therefore named “major life-changing decisions” (MLCD). In Bhatti’s study (9), MLCD are described for both dermatological and non-dermatological disorders.
In this regard, psoriasis, as the standard model of chronic skin disease, may not only have an impact in terms of quality of life, but also by affecting the MLCD of patients throughout their lives.
To date, some published articles refer to the concept of MLCD (10), and also to a proposal of a validated scale to explore MLCD (11), the Major Life Changing Decision Profile, which is translated and validated in Polish (12). However, there are no research studies evaluating how patients with psoriasis are affected in terms of MLCD, nor which clinical and sociodemographic factors are associated with a greater or lesser impact of the disease over the patients’ lifetime in terms of MLCD.
Therefore, the aims of the current study were: to describe the impact of psoriasis on MLCD in a cohort of patients with psoriasis; and to explore the socio-demographic and clinical factors associated with a greater impact on MLCD, so as to identify potential ways of reducing the cumulative negative impact of the disease on patients’ lives.
A cross-sectional study was performed including patients with psoriasis regardless of disease severity, disease duration and current treatments. Patients were asked about the impact the disease had had on their life-changing decisions. Socio-demographic, clinical and treatment variables were also collected.
Patients included in the study were seen at the Dermatology Department (Psoriasis Clinic) of the Virgen de las Nieves University Hospital, Granada, Spain. Patients were asked to participate in a conversation in which they were questioned about the impact of the disease on the decisions made throughout their lives. Patients were recruited between August 2022 and January 2023. Sequential sampling was performed. This study has been approved by the Institutional Review Board of the Virgen de las Nieves University Hospital (Study ID 0671-N-22).
Inclusion criteria were: patients with a clinical diagnosis of psoriasis, regardless of the severity of the disease and the treatment followed; age 18 years or older; and informed consent to be included in the study.
Exclusion criteria were: patient’s refusal to participate in the study; patients or controls who had any other major disease that may have impacted their life decisions.
The current study was approved by the Research Ethics Committee of Virgen de las Nieves University Hospital (Study ID 0671-N-22) and is performed in accordance with the principles of the Declaration of Helsinki.
Main variables. The main variables included those related to the impact of psoriasis on MLCD. These variables were measured by the patient following a 4-point Likert scale (13) which ranged from “0: No impact at all” to “4: Significant impact”. The MLCD considered were some of those originally described by Bhatti et al. (9), and were as follows:
Other variables. Socio-demographic, biometric and clinical variables, including age, sex, and disease severity measured as Psoriasis Area Severity Index (PASI) (14) and Body Surface Affected (BSA) (15), comorbidities, such as psoriatic arthritis, identified using Classification for Psoriatic Arthritis (CASPAR) criteria (16), current treatments for psoriasis, occupation and educational level were recorded via questionnaires and clinical examination.
Descriptive statistics were used to evaluate the characteristics of the sample. The Shapiro–Wilk test was used to assess the normality of the variables. Continuous variables are expressed as mean and standard deviation (SD). Likert scale scores are expressed as median and interquartile range (IQR). Qualitative variables are expressed as relative and absolute frequency distributions. The kappa index was used to explore the concordance between observations. The χ2 test or Fisher’s exact test, as appropriate, were used to compare nominal variables, and the Student’s t-test or Wilcoxon-Mann-Whitney test were used to compare nominal and continuous data. To explore possible associated factors, simple linear regression was used for continuous variables. The β coefficient and SD were used to predict the log odds of the dependent variable. Statistical significance was considered if p-values were less than 0.05. Statistical analyses were performed using JMP version 14.1.0 (SAS Institute, Cary, NC, USA).
A total of 134 patients were initially asked to participate in the study. Of these, a final total of 113 (84.2%, 113/134) patients were included. Mean age of the patients was 51.8 years (SD 13.78) and female to male ratio was 1.08 (54:50). Most patients had a long duration of disease (mean disease duration 23.33 years, SD 16.51), were actively working (56.7%, 64/113) and had university or professional studies (55.7%, 63/113).
Regarding clinical variables, the mean BSA was 5.56% (SD 12.7) and the mean PASI was 3.75 (SD 9.78). Most patients (79.64%, 90/113) were on biologic treatment. A third of patients had psoriatic arthropathy (30.9%, 35/113). Detailed information is shown in Table I.
Patients and dermatologists were asked to assess the severity of the disease and its impact on life decisions. As shown in Table I, patients perceived a higher severity and scored higher for the impact of the disease on life decisions compared with dermatologists, showing poor concordance (kappa index < 0.20).
A variety of MLCD were explored (Table II). It was found that the MLCD most affected by psoriatic disease were those associated with career choice (median (IQR) score 3 (2–4)), social relationships (2 (1–3)), and choice of clothing (2 (1.3)). Other affected domains of MLCD were job performance, absenteeism days, choice of holiday destination, sexual activity, and family relationships (1 (0–2) for all of them). The percentage of patients having a moderate or severe impact of disease on most affected MLCD is shown in Fig. 1.

In contrast, psoriasis had less impact in terms of MLCD on salary, decision to take early retirement, educational performance and level of education achieved, choice of partner (median (IQR) score 0 (0–1)), choice of a place to live and choice of house characteristics (0 (0–0)).
Univariate analyses were performed to explore the clinical and socio-demographic factors associated with MLCD in patients with psoriasis. The most affected MLCD were included in the analysis: career choice, job performance, absenteeism days, social relationships, choice of clothing and choice of holiday destination (Table III).
The most important factors associated with MLCD in patients with psoriasis were: female sex, which was associated with a greater impact of psoriasis on MLCD regarding social relationships, choice of clothing and holiday destination (p < 0.005). An early age of onset was associated with a greater impact on MLCD regarding absenteeism, social relationships, choice of clothing and holiday destination (p < 0.05), but showed a trend for all the MLCD explored. Psoriatic arthropathy was related to a greater impact on all MLCD explored except holiday destination. Finally, being unemployed showed similar results to psoriatic arthropathy.
Notably, the subjective impression of the dermatologist about the intrusiveness of the disease throughout the patient’s life was not associated with most MLCD. Moreover, current disease severity measured by PASI and BSA was inconsistently associated with the different MLCD.
Univariate analyses were performed to explore the clinical and socio-demographic factors associated with MLCD in patients with psoriasis (Table IV). Salary, choice of a place to live, decision to have children and anxiolytic drugs taken were the MLCD explored.
The most important associated factors were: female sex, which was associated with a greater impact of psoriasis on lifetime salary, choice of place to live, and anxiolytic drugs taken (p < 0.05); younger age, which was associated with a higher impact on MLCD regarding the choice of a place to live and the decision to have children (p < 0.01); psoriatic arthropathy, which was associated with an impact on MLCD regarding salary, decision to have children and anxiolytic drugs taken (p < 0.01); and, finally, being unemployed was associated with all the MLCD explored.
As above, the subjective impression of the dermatologist about the intrusiveness of the disease over the patient’s lifetime was not associated with most MLCD. Moreover, current disease severity measured by PASI and BSA was inconsistently associated with the different MLCD.
Psoriasis is a chronic skin disease that seems to have a significant impact on patients’ MLCD. The most affected MLCD are career choice, job performance, absenteeism days and choice of clothing. Moreover, some specific clinical factors seem to be associated with a greater impact of the disease in terms of MLCD.
In this regard, the identification of factors associated with increased MLCD is crucial for limiting the long-term negative effects of psoriasis on patients’ lives. In the current study, among others, 3 specific factors have been found: female sex, joint involvement, and early onset of the disease.
Furthermore, as in quality of life (17), and life-changing decision studies (18), female patients seem to experience a greater impact of the disease in terms of life decisions and are more prone to development of psychological distress. The cause of this association is unclear. On the one hand, sex differences have been found in emotion regulation mechanisms in patients with psoriasis (19). On the other hand, there are probably cultural and social reasons, typical of modern society, the detailed analysis of which is beyond the scope of this study.
Moreover, psoriatic arthropathy appears to play an important role in changing the life decisions of patients with psoriasis. The current study has shown the significant impact of this comorbidity in terms of career choice, job performance, days of absenteeism, social relationships, salary and choice of place to live. Physical limitations caused by joint pain and functional impotence are probably responsible for these findings, and future studies including MLCD specifically related to the physical domain would be of great interest. Despite the lack of specific studies addressing lifetime decisions, quality of life studies also highlight the importance of psoriatic arthritis in terms of quality of life impairment (20). Therefore, it seems that early and effective treatment for joint involvement is crucial to limit the lifetime impact of psoriasis.
Finally, early age of onset of the disease has been linked to a greater burden in terms of absenteeism, social relationships, choice of clothing and holiday destination, as well as choice of place to live. In this regard, previous studies have addressed the importance of the onset of chronic skin diseases during paediatric or adolescent ages (21): chronic skin diseases put paediatric patients at risk of strained family relationships, poor self-image, psychiatric comorbidities, stigmatization, and eventual suicidal behaviour. Therefore, early diagnosis and proper treatment are key to avoiding the dysfunction accumulated throughout the lives of these patients.
Regarding disease severity, the current study showed inconsistent results regarding its relationship with MLCD and mean PASI values were not remarkably high. However, this could be biased, since most patients were currently undergoing advanced psoriasis treatments. Moreover, despite having well-controlled psoriasis at the current time, many patients may have experienced MLCD influenced by their previously very severe psoriasis over many years.
It should be noted that the dermatologist’s subjective assessment does not seem to correlate with the real impact of psoriasis over the patients’ lifetime. Thus, it seems necessary to perform a specific evaluation, asking patients about the impact of the disease over time. These findings are similar to those observed for disease severity and disease symptomatology (22), with patients and dermatologists showing different opinions.
In addition, Bhatti et al. (9), who described the concept of MLCD, have created a questionnaire, the Major Life Changing Decision Profile (MLCDP) (11) based on their initial qualitative study. The MLCDP may be added as a further measure of disease severity or disease impact in future studies on skin disorders, and it would be of great interest to perform this routinely on patients with psoriasis who are visiting the dermatologist, to inform clinical decision making.
The main limitations of the current study are its cross-sectional nature, which makes it impossible to assess causality, the probable overrepresentation of patients with more severe disease, and the limited sample size, which could have led to limited detection of statistical differences.
In conclusion, some MLCD seem to be more significantly affected in patients with psoriasis, such as career choice, job performance, absenteeism days or choice of clothing. The detection of factors associated with greater impact on MLCD, such as female sex, psoriatic arthritis, or early age of onset, is crucial for limiting the long-term negative effects of the disease on patients. The future development of validated tools to assess MLCD in patients with psoriasis, as well as the study of MLCD in patients’ cohabitants, would be of great interest in order to include this measure as a disease characteristic in future studies.
