Correlation of skin-related quality of life with anxiety and depression in chronic dermatoses: A cross-sectional study

Background

Dermatology and psychiatry are two specialties which often have a bearing on each other. Multiple indices have been used to study the quality of life in skin diseases; however, very few studies have correlated these indices with questionnaires of common psychiatric comorbidities like anxiety and depression.

Methods

The study was conducted in a dermatology out patient department (OPD) of a tertiary care hospital. All patients with chronic dermatological conditions (meeting the inclusion criteria) were included, and each patient was made to fill two questionnaires that are Skindex-29 for skin-related quality of life and Beck Depression Inventory (BDI-II) for depression. They were also assessed for anxiety using the Hamilton Anxiety Scale (HAM-A), which was filled under the supervision of a psychiatrist.

Results

The scores for the common diagnoses were collated and analyzed using SPSS 20.0 software, and the results were tabulated. It was found that both the HAM-A and BDI-II had a moderate positive correlation with the Skindex which was statistically significant. Also, on correlating the individual domains of the Skindex with the HAM-A and BDI, the domain of emotions depicted the best correlation.

Conclusion

The study brings to light that a relatively easy to administer quality of life questionnaire can be used as a screening tool to identify psychiatric morbidity and in a busy skin OPD, questions from the emotion domain can only be asked for early referral to a psychiatrist.

Reliability and validity of the Turkish version of Scleroderma Skin Patient-Reported Outcome in patients with systemic sclerosis

Objectives

This study aimed to translate the Scleroderma Skin Patient-Reported Outcome (SSPRO) questionnaire to the Turkish (SSPRO-T) language and to assess its validity and reliability.

Patients and methods

Fifty-four systemic sclerosis (SSc) patients (51 females, 3 males; mean age: 49.8±10.4 years; range, 22 to 65 years) participated in the reliability and validity analysis between October 2022 and December 2022. The translation and cross-cultural adaptation of the SSPRO-T was applied in accordance with the procedure described by the Beaton guidelines. The SSPRO-T, the Scleroderma Health Assessment Questionnaire (SHAQ), the Health Assessment Questionnaire Disability Index (HAQ-DI), Skindex-29, and patient global skin severity were conducted in all participants for construct validity. The SSPRO-T was retested to assess its reliability after seven days.

Results

The SSPRO-T had a four-factor structure. The total SSPRO-T score and its subgroups correlated positively with SHAQ, HAQ-DI, Skindex-29, and patient global skin severity. The internal consistency and reliability were excellent in overall SSPRO-T and in the subgroups: physical effect, emotional effect, physical limitation, and social effect (Cronbach's α=0.94, 0.80, 0.95, 0.93, and 0.84, respectively). The SSPRO-T had excellent test-retest reliability (r=0.91, p<0.001). In addition, no floor effect or ceiling effect was observed.

Conclusion

The SSPRO-T questionnaire is a reliable and valid tool and can be used in research and clinical practice in Turkish patients with SSc.

Risk factors of striae gravidarum and chloasma melasma and their effects on quality of life

OBJECTIVE

This study aims to determine the risk factors associated with striae gravidarum (SG) and chloasma melasma (CM) and their effects on the quality of life.

METHODS

This descriptive and cross-sectional study was carried out in Turkey with 1000 pregnant women at 36 weeks of gestation and above. Personal information form, Quality of Life (SF36) Scale, Skindex-29 Scale, and MelasQoL-TR questionnaire were applied to pregnant women. Besides, skin types of pregnant women were determined using Fitzpatrick Skin Type Classification. Davey's score was used to determine the severity of SG.

RESULTS

In the study, the prevalence of SG was found as 67.9% (n = 679), and the prevalence of CM 23.5% (n = 235). There was a significant relationship between young age, low education level, high BMI before pregnancy, history of SG in her previous pregnancy, family history of SG, and development of SG in pregnant women (p = 0.001). There was a significant relationship between CM in her previous pregnancy and family history of CM and development of CM (p = 0.001). The quality of life of pregnant women with SG was found to be lower than without SG (p < 0.001). The quality of life of pregnant women with CM was found to be lower than without CM (p < 0.001).

CONCLUSIONS

As a result, in the study, it was determined that young age, low education level, high BMI, history of SG in previous pregnancy, and family history of SG were risk factors for SG. The risk factors of CM, on the other hand, were found as the history of CM in the previous pregnancy and the family. It was identified that SG and CM have adverse effects on the quality of life.

Quality of life of cutaneous leishmaniasis suspected patients in the Ecuadorian Pacific and Amazon regions: a cross sectional study

Background

Yearly, up to 1 million patients worldwide suffer from cutaneous leishmaniasis (CL). In Ecuador, CL affects an estimated 5000 patients annually. CL leads to reduced Health Related Quality of Life (HRQL) as a result of stigma in the Asian and Mediterranean contexts, but research is lacking for Ecuador. The objective of this study was to explore the influence of CL suspected lesions on the quality of life of patients in the Pacific and Amazon regions.

Methods

Patients for this study were included in the Amazonian Napo, Pastaza, and Morona Santiago provinces and the Pacific region of the Pichincha province. Participating centers offered free of charge CL treatment. All patients suspected of CL and referred for a cutaneous smear slide microscopy examination were eligible. This study applied the Skindex-29 questionnaire, a generic tool to measure HRQL in patients with skin diseases. All statistical analysis was done with SPSS Statistics version 28.

Results

The skindex-29 questionnaire was completed adequately by 279 patients who were included in this study. All patient groups from the Amazon scored significantly (P < 0.01) higher (indicating worse HRQL) on all the dimensions of the Skindex-29 questionnaire than Mestizo patients from the Pacific region. The percentage of patients with health seeking delay of less than a month was significantly (P < 0.01) lower in the Amazon region (38%) than in the Pacific (66%).

Conclusions

The present study revealed that the influence of suspected CL lesions on the HRQL of patients in the Ecuadorian Amazon and Pacific depends on the geographic region more than on patient characteristics such as gender, age, number of lesions, lesion type, location of lesions, health seeking delay, or posterior confirmation of the Leishmania parasite. The health seeking delay in the Amazon might result from a lack of health infrastructure or related stigma. Together, the impaired HRQL and prolonged health seeking delay in the Amazon lead to prolonged suffering and a worse health outcome. Determinants of health seeking delay should be clarified in future studies and CL case finding must be improved. Moreover, HRQL analysis in other CL endemic regions could improve local health management.

Potential adverse effects of prophylactic bilateral salpingo-oophorectomy on skin aging in premenopausal women undergoing hysterectomy for benign conditions

OBJECTIVE

This study aimed to assess the effects of hysterectomy and bilateral salpingo-oophorectomy (BSO)--compared with the effects of hysterectomy alone--on skin aging in premenopausal women undergoing hysterectomy for benign conditions.

METHODS

One hundred thirty-five premenopausal women who underwent hysterectomy with BSO were compared with a control group of women who underwent hysterectomy alone based on skin parameters (including wrinkling, laxity/sagging, and texture/dryness) and Skindex-29 questionnaire scores. The inclusion criteria were as follows: aged between 40 and 50 years, follicle-stimulating hormone level lower than 40 mIU/mL, undergoing hysterectomy with or without BSO for benign conditions, and not receiving estrogen or progesterone treatment. The exclusion criteria were as follows: adrenocortical hyperplasia or Cushing's syndrome; use of corticosteroids for autoimmune diseases; malignancy, connective tissue diseases (eg, Ehlers-Danlos syndrome), or dermatological diseases (eg, lichen sclerosus); or regular use of medications known to interfere with the condition of the skin.

RESULTS

All skin parameters in the hysterectomy group and the hysterectomy with BSO group worsened on weeks 24 and 48. Laxity/sagging and texture/dryness scores on weeks 24 and 48 were significantly worse in the BSO group; laxity/sagging and texture/dryness scores continued to worsen between 24 and 48 weeks. Scores for the Skindex-29 questionnaire emotion and symptom subscales were significantly higher in the BSO group compared with the non-BSO group.

CONCLUSIONS

Prophylactic BSO during hysterectomy is a significant independent risk factor for worsening skin laxity/sagging and texture/dryness in premenopausal women undergoing hysterectomy for benign conditions. Prophylactic BSO in the presence of dermatological conditions is also associated with reduced quality of life.

Development and psychometric validation of the Chinese version of Skindex-29 and Skindex-16

Background

Dermatological disease significantly affects patient’s health-related quality of life (HrQoL). Skindex is one of the most frequently used dermatology-specific HrQoL measures. Currently no Chinese version of Skindex is available. The aim of this study was to translate and culturally adapt Skindex-29 and Skindex-16 into Chinese, and to evaluate their reliability and validity.

Methods

Translation and cultural adaption were performed following guidelines for cross-cultural adaption of health-related quality of life measures. Subsequently, a cross-sectional study was conducted in which patients with dermatological disease (n = 225) were enrolled. The Chinese version of Skindex-29 and Skindex-16 and Dermatology Life Quality Index (DLQI) were completed. Reliability was evaluated with internal consistency using Cronbach’s alpha. Validity was evaluated using known-groups validity, convergent validity and factor structure validity.

Results

There were both seven items of Skindex-29 and Skindex-16 requiring a second forward- and backward- translation to achieve the final satisfactory Chinese version. The internal consistency reliability was high (range of Cronbach’s alpha for the scales of Skindex-29 0.85-0.97, Skindex-16 0.86-0.96). Known-group validity was demonstrated by higher scores from patients with inflammatory dermatosis than from patients with isolated skin lesions (P < 0.05). Evidence of factor structure validity of the Skindex-29 and Skindex-16 was demonstrated by both exploratory factor analysis that accounted for 68.66% and 77.78% of the total variance, respectively, and confirmatory factor analysis with acceptable fitness into the expected three-factor structure.

Conclusion

This study has developed semantically equivalent translations of Skindex-29 and Skindex-16 into Chinese. The evaluation of the instruments’ psychometric properties shows they have substantial evidence of reliability and validity for use as HrQoL instruments in Chinese patients with dermatological disease.

Translation, cultural adaptation, and validation of the American Skindex-29 quality of life index

BACKGROUND

Measuring the quality of life measure of patients with dermatologic diseases is an important concern. The instruments to evaluate it are commonly originally written in English and need to be translated and validated to be used in different cultures.

OBJECTIVE

The purpose of this paper is to translate and validate the Skindex-29 questionnaire to Brazilian Portuguese to be used in our country as a quality of life assessment instrument in dermatologic patients.

METHODS

The first step was the translation from English to Brazilian Portuguese and the back-translation by two native speakers. The translated version was then used for the second step, when three questionnaires were applied to 75 patients (43 of whom were classified as lightly affected and 32 as heavily affected by their dermatologic conditions): an identification questionnaire, the translated version of Skindex-29, and the Brazilian Portuguese version of Dermatologic Life Quality Index (DLQI). Additionally, the generic questionnaire Short Form 36 (SF-36) was applied to 41 of these patients. The last step to evaluate reproducibility was repeating the Skindex-29 questionnaire by the same researcher one week later in 44 patients.

RESULTS

Reliability was observed in global Skindex-29 scale (α=0.934), and its domains emotions (α=0.926), symptoms (α=0,702), and psycosocial functioning (α=0.860). The reproducibility showed high intraclass correlations. High intra class correlations was observed, thus validating reliability.

CONCLUSIONS

The Skindex-29 quality of life questionnaire was properly translated and validated to Brazilian Portuguese.

The Polish version of Skindex-29: psychometric properties of an instrument to measure quality of life in dermatology

Introduction

Skin conditions have a negative impact on quality of life and it is necessary to quantify this impact. Skindex-29 is a self-report questionnaire developed to measure dermatology-specific quality of life.

Aim

The objective of this study is to adapt this questionnaire to Polish conditions. The adaptation procedure involved the works on the linguistic content of the items and testing psychometric properties of the Polish version of Skindex-29, including item characteristics, factorial structure, aspects of reliability and validity.

Material and methods

Two-hundred and ninety patients (63.4% women and 35.2% men) suffering from a range of skin conditions were recruited from several dermatological out-patient and in-patient clinics in Poland. Quality of life was measured using Skindex-29 and appropriate clinical data were collected.

Results

The global score of Skindex-29 showed the normal distribution. Cronbach's α reliability coefficients were found to be high to very high for all Skindex-29 indexes. Factor analysis yielded four factors, in contrast to the original version of the questionnaire, for which a three-factor solution had been reported. Skindex-29 validity was demonstrated by showing the differences in the quality of life scores across different diagnostic categories, and between in-patients and out-patients. Skindex-29 global scores were found to be significantly predicted by the localization of the skin lesions on legs, anogenital areas and palms.

Conclusions

The findings of this study support reliability and validity of the Polish version of Skindex-29, but they also raise questions to its three-factor structure.

Effect of the pruritus on the quality of life: a preliminary study

Background

Pruritus affects the quality of life (QoL) in the patients. However, little is known of the impacts of itching on the QoL in the literature.

Objective

In this study, a questionnaire eliciting specific responses about pruritus was used to determine the effect of itching and its severity on QoL in chronic pruritic patients.

Methods

One hundred ten adult patients with chronic pruritus were surveyed. Once itch severity had been self-reported by patients, together with Skindex-29, they have been given the 18-item Pruritus-related Life Quality Index (PLQI) questionnaire, which was used to generated the new index.

Results

Significant correlations have been found between the pruritus severity score of participants and their total Skindex-29 (p<0.001) with its function, emotion and symptom subscale scores (p<0.001 for each). Also, significant correlations were evident between total PLQI (p<0.001) and its psychosocial negativities, difficulties in everyday activities and social live subscale scores (p<0.001 for each). In particular, the emotion subscale of Skindex-29 (p=0.02) and psychosocial negativity subscale of PLQI (p=0.02) were significantly high in psychopathologic patients. A highly positive statistical correlation between Skindex-29 and PLQI scales was evident (r=0.845, p<0.001). For reliability, Cronbach's coefficient a coefficients were 0.931 for the Skindex-29 scale and 0.918 for the PLQI scale.

Conclusion

The results demonstrate that chronic pruritus appreciably reduces the QoL. PLQI could be used in the development of new questionnaires for determining the QoL of patients with chronic itch.

Quality of life evaluation in Japanese pregnant women with striae gravidarum: a cross-sectional study

Background

Striae gravidarum is a physiological skin change that many pregnant women experience during pregnancy. The striae are often accompanied by a reddish purple color during pregnancy, and then lose pigmentation and become atrophic in the long term after pregnancy. Striae gravidarum seems to be undesirable to many pregnant women. However, the impact of striae gravidarum on pregnant women who experience it has not been clarified. The aim of this study was to evaluate the impact of striae gravidarum on the generic and dermatology-specific quality of life (QOL) of pregnant women.

Methods

A cross-sectional study was conducted at three private clinics in a typical urban area in Japan. We recruited 447 pregnant women at 36 weeks of gestation; One hundred and ninety-nine pregnant women at 36 weeks of gestation participated in the study and 179, consisting of 94 primiparae and 85 multiparae, were analyzed.

We used and assessed Davey’s score for striae gravidarum, World Health Organization Quality of Life assessment questionnaire for generic QOL, and Skindex-29 for dermatology-specific QOL.

Results

The prevalence of striae gravidarum was 39.1% (27.7% in primiparae, and 51.8% in multiparae). Although there were no differences in generic QOL scores between the presence and absence of striae gravidarum and with their severity, the whole group of pregnant women and the multiparae group showed significant differences in scores on emotion of Skindex-29 between the presence and absence of striae gravidarum (p = 0.012 and p = 0.011). Pregnant women with severe striae gravidarum showed significantly higher scores on emotion of Skindex-29 compared with those with absent or mild striae gravidarum (p < 0.001 and p = 0.005).

Conclusions

There was no difference in generic QOL of pregnant women between the presence and absence of striae gravidarum, although the occurrence and severity of striae gravidarum influenced their dermatology-specific QOL. Multiparae women were especially impaired by striae gravidarum and it is considered important to prevent or reduce the severity of striae gravidarum of the multiparae group.

Adaptation of a Runyankore version of Skindex-16 for oral administration in Mbarara, Uganda

BACKGROUND

Health-related quality of life instruments are typically developed and validated for use in developed countries by patients who can read and write. Little is known about the feasibility of using adaptations of validated instruments in situations where literacy rates are low.

OBJECTIVE

We aimed to translate, culturally adapt, and test an oral version of Skindex-16 in Runyankore, the predominant language in Mbarara, Uganda, for use in dermatologic research.

METHODS

Skindex-16 was forward- and back-translated to Runyankore. The Runyankore version was administered orally to 47 dermatology patients and 47 random hospital visitors. Additional questions regarding duration, dyspigmentation, concealment status of the skin problem, and overall quality of life effect were also asked.

RESULTS

Oral delivery was feasible; ≤ 10 minutes per subject. High Cronbach α values (0.86, 0.88, and 0.85 for symptoms, emotions, and functioning subscales, respectively) demonstrated internal consistency reliability. As hypothesized, subjects with reported skin problems, dyspigmentation, and difficulty in concealment had higher mean Skindex scores. A total of 72.4% of responses to the open-ended question were addressed in Skindex-16, indicating content validity.

CONCLUSION

The orally delivered Runyankore version of Skindex-16 is reliable, with construct and content validity, and feasible for use in dermatology research in Mbarara, Uganda. Orally administered quality of life instruments have potential for use in low literacy groups worldwide.
