Pictorial representation of illness and self measure (PRISM): an effective tool to assess the burden of psoriasis

The Dermatology Life Quality Index (DLQI) used as the benchmark in validation of 101 quality-of-life instruments: A systematic review

BACKGROUND

The validation of psychometric measures requires use of other established and standardized validated measures. The Dermatology Life Quality Index (DLQI) is the most widely used tool to measure the burden of skin diseases and assess effectiveness of interventions based on patients' perspective.

OBJECTIVES

The objective of this study was to systematically analyse peer-reviewed publications describing use of the DLQI in validation of other patient-reported outcome (PRO) and quality-of-life (QoL) measures.

METHODS

Seven databases were searched for papers published between January 1994 and December 2022 for articles containing data using DLQI in the validation of other PRO/QoL measures. The methodology followed PRISMA guidelines. The protocol was prospectively registered on PROSPERO.

RESULTS

Of 1717 screened publications, 122 articles including 30,727 patients from 34 different countries with 41 diseases met the inclusion criteria. The DLQI was used in validation of 101 measures: 80 dermatology-specific QoL measures, mostly disease-specific, and 21 generic measures. Of these studies, 47 were cross-cultural adaptations, 116 single arm, 100 were cross-sectional, 18 longitudinal and six randomized placebo controlled. DLQI was used for 14 known group, and correlation for 10 construct, 101 convergent, 10 concurrent, 10 divergent/discriminant and three criterion validity tests using Mann-Whitney (2), Spearman's (80), Pearson's correlation (26) and Student's t-test (1). The DLQI was used in responsiveness analysis in 13 studies.

CONCLUSIONS

This review identified widespread use of the DLQI in validation of other dermatology PRO/QoL measures and confirmed the central role that the DLQI plays as a benchmark in instrument development and validation across dermatology and beyond. The use of the DLQI by so many developers of other instruments has provided a common standard for comparability.

Assessing Psychosocial Burden in Psoriasis Patients Using the PRISM-RII Tool: A Comprehensive Evaluation

INTRODUCTION

Psoriasis is a chronic, immune-mediated inflammatory disease that significantly impacts patients' quality of life due to its visible lesions and associated stigma. Psychological comorbidities are prevalent among psoriasis patients.

OBJECTIVES

This study aimed to evaluate the utility of the Pictorial Representation of Illness and Self Measure Revised II (PRISM-RII) tool in assessing the psychosocial burden, including internalized stigma, in psoriasis patients.

METHODS

A cross-sectional study was conducted with 190 psoriasis patients recruited from a university hospital dermatology treatment center. Participants completed the PRISM-RII Psoriasis Internalized Stigma Scale (PISS), Hospital Anxiety and Depression Scale (HADS), and Dermatology Life Quality Index (DLQI). Clinical severity was measured using the Psoriasis Area and Severity Index (PASI).

RESULTS

Significant correlations were observed between PRISM-RII parameters and measures of quality of life, internalized stigma, anxiety, and depression. Our study revealed significant differences in PASI scores among different Illness Perception Measures (IPM). A negative correlation was found between PASI and Self-Illness Separation (SIS), suggesting that increased disease severity is associated with a higher perceived burden of illness. Additionally, significant negative correlations were observed between SIS and DLQI, HADS, and PISS. Patients with larger IPM reported higher levels of anxiety, depression, and internalized stigma, as well as lower treatment satisfaction.

CONCLUSIONS

The PRISM-RII tool effectively captures the psychosocial burden of psoriasis including internalized stigmatization, highlighting the need to address both physical and psychological aspects in clinical practice. Incorporating PRISM-RII into routine assessments can enhance patient-centered care by identifying and addressing the psychosocial dimensions of psoriasis.

Pilot study to evaluate a novel measure of self-perceived competencies among dental students

BACKGROUND

PRISM is a novel approach to support self-reflection and learning appraisal in dental students, based on a visual metaphor. The aim of this study was to evaluate whether PRISM measurments would be reproducible and sensitive to detect learning progress in undergraduate dental students in their clinical years.

METHODS

Voluntarily participating dental students were included. To evaluate reproducibility, a mixed cohort of 10 students each in 3^rd, 4^th and 5^th year (total n = 30) was recruited and received three identically structured PRISM interviews within one week without any other teaching events. To assess perceived learning progress, 29 volunteer 3^rd year students participated in three interviews during their clinical simulation course (beginning, middle, end). Distances between Subject and Objects was measured in millimeter; objects were classified into close or branched clusters depending on their distance from each other on the PRISM board.

RESULTS

Values for perceived competencies within PRISM interviews during one week were comparable between the three time points in the mixed cohort (n = 30; p > 0.05). Comparing the three subgroups (3^rd, 4^th and 5^th year, each n = 10), PRISM indicated that 3^rd year students perceived their competencies are significantly lower than the 4^th and 5^th year students (p < 0.01). 3^rd year students had less often a branched cluster of objects than the other two groups (p < 0.05). PRISM showed that over time, 3^rd year students perceived a gain in their competencies in conservative dentistry and its sub-disciplines (p ≤ 0.01). The PRISM data indicated that by the end of the simulation course, the students appeared to show higher discrimination of their self-perceptions between sub-topics in conservative dentistry than at the start of the course (p = 0.01).

CONCLUSION

PRISM yields a reproducible measure of individual students' learning progress. It is a promising novel approach for appraisal in dental education. Further work is needed to confirm the generalisability of the findings.

Risk Perception of Natural and Human-Made Disasters-Cross Sectional Study in Eight Countries in Europe and Beyond

Each year, emergency and disaster situations claim a heavy toll in human lives and economic loss. Civilian populations that are more aware and prepared for emergencies are more resilient. The aim of this study was to explore similarities and differences in risk perception of emergencies and disasters across different societies and its association with individual resilience. A cross sectional study that explored attitudinal factors, as expressed by diverse samples of target countries across Europe and beyond, took place during the months of January-February 2021. Diverse samples (N ≥ 500) of adults from 8 countries (Italy, Romania, Spain, France, Sweden, Norway, Israel, and Japan) were engaged in this study. This study used the Pictorial Representation of Illness and Self-Measure (iPRISM) tool to assess risk perception. The results suggest that for the overall sample (N = 4,013), pandemics were the risk of which participants showed the highest concern, followed by critical infrastructure fail, social disturbance, natural hazards, and extreme weather events. It was found that religiosity is associated with risk perception, with highly religious and non-religious reporting elevated risk perception (F = 5.735, df = 2, p = 0.003), however country-specific analysis revealed that this finding varies depending on local contexts. The analysis also revealed differences in risk perception depending on age and type of risk. The results of this study present that there are commonalities and differences between societies across Europe and beyond concerning societal resilience at large, including risk perception. The dependency of risk perception on local context suggests that a regional-based approach for disaster risk reduction may be called for to adapt and adjust to local socio-cultural characteristics of each population.

Assessment of the perceived burden associated with Malignant Melanoma with Pictorial Representation of Illness and Self Measure (PRISM) and Melanoma Concerns Questionnaire (MCQ-28)

PURPOSE

The impact of malignant melanoma (MM) on patients' psychophysical well-being has been poorly addressed. We aimed to assess the perceived burden in patients with a diagnosis of MM, using two different tools, one generic and one specific for MM, such as Pictorial Representation of Illness and Self Measure (PRISM) and Melanoma Concerns Questionnaire (MCQ-28), respectively. The correlation between PRISM and MCQ-28 subscales and the relevance of disease and patient-related variables were also investigated.

METHODS

This single-centre, cross-sectional study included all adult consecutive MM patients who attended our Dermatology Unit from December 2020 to June 2021. Demographics and disease-related data were recorded. PRISM and MCQ-28 were administered.

RESULTS

One hundred and seventy-one patients were included (mean age: 59.5 ±14.9 years.; 48.0% males). Median time from MM diagnosis to inclusion was 36 months. Nearly 80% of the patients had in situ or stage I MM. Overall, 22.2% of the patients reported a PRISM score <100mm and similar percentages provided scores indicating impaired quality of life, as assessed with MCQ-28 subscales. A weak, albeit significant, correlation was found between PRISM scores and ACP, CON and SOC2 subscales. The most relevant association found was that between lower PRISM scores and higher-stage MM.

CONCLUSIONS

In the study population, mostly affected with superficial MM, their perception of the burden associated with MM did not appear either particularly dramatic or disabling. PRISM seems a reliable system for capturing and quantifying the domains correlated with the emotive dimension of MM, especially MM-related concerns and willingness to face life.

The "self" in pain: high levels of schema-enmeshment worsen fibromyalgia impact

OBJECTIVE

Chronic pain can have detrimental effects on quality of life and a profound impact on one's identity. The Pictorial Representation of Illness- and Self-Measure (PRISM), is a visual tool designed to measure the self-illness separation (SIS) that represents the degree of schema-enmeshment (i.e., the degree to which the self-schema and the illness-schema come to overlap). Our aim was to investigate the relationship between schema-enmeshment and pain-related outcomes in patients with fibromyalgia.

METHODS

In this cross-sectional study, 114 patients with fibromyalgia completed self-report assessments of pain catastrophizing, pain severity and interference, impact of symptoms, anxiety, and depression. SIS was assessed using an iPad version of PRISM. Mediation analyses evaluated the mediating role of schema-enmeshment on the association between pain catastrophizing and fibromyalgia impact.

RESULTS

A higher degree of schema-enmeshment was associated with greater pain catastrophizing, pain severity and interference, impact of symptoms, and depression. Moreover, a mediation analysis revealed that schema-enmeshment significantly mediated the association between pain catastrophizing and fibromyalgia impact (p < 0.001).

CONCLUSIONS

Our results indicate that schema-enmeshment is associated with greater intrusiveness of chronic pain on everyday life, thereby posing significant limitations on the emotional and physical well-being of fibromyalgia patients. Schema-enmeshment also appears to partly account for the deleterious effect of pain catastrophizing on disease impact. The PRISM is a simple tool that may uniquely capture the extent to which chronic pain and illness infiltrates and affects one's self-concept.

Convergent Validity of Suffering and Quality of Life as Measured by The Hidradenitis Suppurativa Quality of Life

BACKGROUND

Hidradenitis suppurativa (HS) is a painful chronic, recurrent inflammatory skin disease with great impact on health-related quality of life (HRQOL). Recently, Hidradenitis SuppuraTiva cORe outcomes set International Collaboration (HISTORIC) established HRQOL as a core domain set for HS clinical trials and developed the Hidradenitis Suppurativa Quality of Life (HiSQOL) as a validated outcome measurement instrument.

OBJECTIVES

To provide further convergent validity of HiSQOL by comparing it to Dermatology Life Quality Index (DLQI) and Pictorial Representation of Illness and Self Measure-Revised 2 (PRISM-R2).

METHODS

In this cross-sectional study, 103 participants completed HiSQOL, PRISM-R2 and DLQI. PRISM-R2 is an instrument designed to measure suffering and reports the two measures, Illness Perception Measure (IPM) and Self-Illness Separation (SIS). Correlation analyses were performed including a sub-analysis for a subgroup of patients with high scores in the HS-specific domains of HiSQOL.

RESULTS

A very strong correlation was found between HiSQOL and DLQI (ρ = 0.93, P < 2.2 × 10^-16 , (95% CI: 0.89;0.95)), and moderately strong correlations were found between HiSQOL and SIS (ρ = -0.73, P < 2.2 × 10^-16 , (95% CI: -0.81; -0.62)) and DLQI and SIS (ρ = -0.70, P < 2.2 × 10^-16 , (95% CI: -0.79; -0.59)). IPM was positively associated with HiSQOL and DLQI and negatively with SIS.

CONCLUSIONS

HiSQOL is a valid measure of quality of life for HS patients, and we suggest that HiSQOL can be used as a measure of suffering as well.

Measuring perceived benefit and disease-related burden in patients affected with vulvar lichen sclerosus after a standard topical corticosteroid treatment. Results from a cohort study using Pictorial Representation of Illness and Self-measure and Dermatology Life Quality Index

Improvement in suffering after treatment has been poorly investigated in women affected with vulvar lichen sclerosus (VLS). We performed an observational study on a cohort of VLS patients for assessing the effect of a 12-week topical corticosteroid treatment on their VLS-related burden, as measured with Pictorial Representation of Illness and Self-Measure (PRISM) and Dermatology Life Quality Index (DLQI). Demographics and disease-related subjective and objective scores (at baseline, T0, and at the control visit, T1) were recorded. The PRISM and DLQI were administered at T0 and T1. We assessed the variation of PRISM and DLQI at T1 compared to baseline and the relevance of several variables on these changes. Sixty-three patients were included. A significant improvement was found in both PRISM and DLQI after treatment. A higher coefficient of variations was observed for PRISM and DLQI as compared to subjective and objective scores. Improvement of global subjective score after treatment was the sole variable associated with PRISM and DLQI variations. The corticosteroid treatment led to a significant decrease in the impact of VLS on patients' well-being, in terms of suffering and quality of life impairment. PRISM seems a reliable instrument for integrating clinicians' and patients' perspectives for a comprehensive VLS management.

Pictorial Representation of Illness and Self-Measure to assess the perceived burden in patients with chronic inflammatory vulvar diseases: an observational study

BACKGROUND

Chronic inflammatory vulvar diseases can have a huge detrimental impact on patient welfare. A few studies have addressed this issue so far, mainly measuring patients' quality of life or sexual dysfunction.

OBJECTIVE

To assess the burden of suffering in patients with chronic inflammatory vulvar diseases using the Pictorial Representation of Illness and Self-Measure (PRISM), a visual, non-verbal instrument. We also assessed (i) the concordance between PRISM and the Dermatology Life Quality Index (DLQI), (ii) whether some variables, both patient-related and disease-related, affect the patient's suffering and quality-of-life impairment.

METHODS

We evaluated for inclusion in this cross-sectional study all patients who attended our Vulva Unit over a 9-month period with histologically proven lichen sclerosus (LS), lichen planus (LP), lichen simplex chronicus (LSC), eczema, plasma cell vulvitis and psoriasis (at least five for each disease). Demographics and disease-related subjective and objective scores were recorded. The PRISM and DLQI were administered.

RESULTS

We included 87 patients affected with LS, 13 with LSC and seven with LP. Median PRISM values (0-273 mm) ranged from 95 to 120 mm, depending on the disease, and median DLQI scores (0-30) were five for all three groups. Neither PRISM nor DLQI scores differed significantly among the three groups. Moderate coherence was found between PRISM and DLQI (ρ = 0.5455, P < 0.001). Global subjective score was the only variable significantly associated with the degree of suffering and quality-of-life impairment.

CONCLUSIONS

Pictorial Representation of Illness and Self-Measure proved to be a valuable, highly reliable tool for measuring the perceived burden in these patients. In spite of a moderate correlation, PRISM resulted more sensitive in capturing patient distress than DLQI.

Pictorial Representation of Threat Perception and Its Association With Emergency Preparedness

OBJECTIVES

Emergency preparedness is a key factor in public resilience when facing adversities. It is widely agreed that populations who are better prepared for crises and emergencies cope better and sustain fewer damages. Yet, promoting readiness continues to be challenging. In an effort to assess Israeli threat perception of emergencies, a novel visual tool measuring personally salient appraisals and attitudes (the Pictorial Representation of Illness and Self-Measure [PRISM]) was used.

METHODS

A cross-sectional study of 502 participants representing the adult Jewish population was carried out. An online version of the PRISM tool was used together with a set of validated questionnaires to assess household preparedness.

RESULTS

The results suggest that preparedness for emergencies (war or earthquake) is associated with the way subjects appraise preparedness in their lives, but is not associated to the appraisal of threat objects themselves. In other words, the results suggest that preparedness has little to do with threat perception.

CONCLUSIONS

This study highlights the disparity between classic risk reduction strategies, which argue that awareness is key in promoting public preparedness, and the reality.

Try to see it my way: exploring the co-design of visual presentations of wellbeing through a workshop process

AIMS

A 10-month project funded by the NewMind network sought to develop the specification of a visualisation toolbox that could be applied on digital platforms (web- or app-based) to support adults with lived experience of mental health difficulties to present and track their personal wellbeing in a multi-media format.

METHODS

A participant co-design methodology, Double Diamond from the Design Council (Great Britain), was used consisting of four phases: Discover - a set of literature and app searches of wellbeing and health visualisation material; Define - an initial workshop with participants with lived experience of mental health problems to discuss wellbeing and visualisation techniques and to share personal visualisations; Develop - a second workshop to add detail to personal visualisations, for example, forms of media to be employed, degree of control over sharing; and Deliver - to disseminate the learning from the exercise.

RESULTS

Two design workshops were held in December 2017 and April 2018 with 13 and 12 experts-by-experience involved, respectively, including two peer researchers (co-authors) and two individual-carer dyads in each workshop, with over 50% of those being present in both workshops. A total of 20 detailed visualisations were produced, the majority focusing on highly personal and detailed presentations of wellbeing.

DISCUSSION

While participants concurred on a range of typical dimensions of wellbeing, the individual visualisations generated were in contrast to the techniques currently employed by existing digital wellbeing apps and there was a great diversity in preference for different visualisation types. Participants considered personal visualisations to be useful as self-administered interventions or as a step towards seeking help, as well as being tools for self-appraisal.

CONCLUSION

The results suggest that an authoring approach using existing apps may provide the high degree of flexibility required. Training on such tools, delivered via a module on a recovery college course, could be offered.

Recognising ethnocultural diversity in chronic pain assessment: validation of the Pictorial Representation of Illness and Self Measure (PRISM) for use with culturally diverse communities

BACKGROUND

A comprehensive and accurate assessment of pain is critical for successful pain management. However, there is a lack of reliable and valid assessment tools for exploring multidimensional aspects of the chronic pain experience in culturally and linguistically diverse communities. This study investigates the reliability and validity of the Pictorial Representation of Illness and Self Measure + (PRISM+) for evaluating pain-related suffering and the sociocultural context of chronic pain within culturally and linguistically diverse patient cohorts.

METHOD

Three prospective validation studies are reported for three culturally and linguistically diverse communities. Two hundred and fifty-one patients with chronic pain who self-identified as Assyrian (n = 85), Arabic (n = 83) or Vietnamese (n = 83) completed a PRISM+ assessment, alongside a battery of standardised pain assessments. To evaluate construct validity, the position of the 'pain' disk placement was correlated with the Brief Pain Inventory (BPI), Depression Anxiety and Stress Scale (DASS), and the Short-Form 36 Health Survey (SF-36). For content validity, thematic analysis of patient narratives accompanying each disk placement was conducted. Test-retest reliability of repeated 'pain' and five additional disks (PRISM+) values was analysed using intra-class correlation coefficients.

RESULTS

The PRISM pain assessment demonstrated moderate to good test-retest reliability for Arabic (ICC 0.76; 95% CI 0.65-0.84), Assyrian (ICC 0.65; 95% CI 0.50-0.76) and Vietnamese (ICC 0.82; 95% CI 0.73-0.88) patients. Moderate correlations between the PRISM 'pain' disk and sub-scores for the BPI, DASS and SF-36 were found (p < 0.001). Patient interpretations of the 'pain' disk aligned with accepted definitions of suffering, supporting content validity for PRISM. For the additional disks (PRISM+), moderate to good test-retest reliability (ICC 0.67-0.88) was observed and qualitative analysis highlighted each disk reflected social and cultural values.

CONCLUSION

The PRISM demonstrates acceptable psychometric properties for measuring pain-related suffering for participants with chronic pain across three culturally and linguistically diverse communities. The use of additional disks (PRISM+) presents a reliable and valid option for exploring social and cultural dimensions of chronic pain in clinical encounters.

Pictorial Representation of Illness and Self Measure (PRISM): A Novel Visual Instrument to Quantify Suffering in Liver Cirrhosis Patients and Liver Transplant Recipients

Background

The level of suffering of chronically ill patients does not necessarily correlate with illness severity. In this study, we evaluated the burden of suffering and its impact on health-related quality of life in liver transplant recipients and liver cirrhosis patients.

Material/Methods

The Pictorial Representation of Illness and Self Measure (PRISM) was used to explore levels of suffering in outpatients of Münster University Hospital, Germany. Self-illness separation scores were analyzed as a measure of disease-specific burden of suffering. Health-related quality of life was measured using the Short Form Health Survey (SF-36).

Results

Data from 201 subjects were statistically analyzed. Median Self-illness separation scores for liver transplant recipients and patients with liver cirrhosis were 13.5 (minimum/maximum: 0.2/25.6) cm and 6.3 (0.1/25.6) cm (p<0.001), respectively. The median SF-36 Mental Component Summary and Physical Component Summary scores were 46.4 (12.5/66.2) and 40.1 (12.3/61.1), respectively. Higher health-related quality of life was associated with greater self–illness separation. Liver transplant recipients showed normal Mental Component Summary scores compared with the general German population; patients with liver cirrhosis had significantly lower Mental Component Summary scores. Physical Component Summary scores were significantly higher in liver transplant recipients than in patients with liver cirrhosis, but still lower than in the general population.

Conclusions

PRISM is a novel, simple tool for measuring the illness burden in liver transplant recipients and patients with liver cirrhosis. This measure may help to identify patients at a higher risk of psychological disorders.

Pictorial Representation of Illness and Self Measure-Revised 2 (PRISM-R2): an effective tool to assess perceived burden of thyroid cancer in mainland China

PURPOSE

Thyroid cancer, especially differentiated thyroid cancer (DTC), is a highly prevalent chronic disease that is known to cause considerable distress, related both to the high recurrence and treatment of the disease. The Pictorial Representation of Illness and Self Measure-Revised 2 (PRISM-R2) has been developed as a visual measure to assess suffering. The aim of this study was to evaluate the ability of the instrument to identify patients with DTC with different levels of suffering who may need additional support care.

METHODS

Participants were 338 adult inpatients with DTC who were accepting the radioiodine for remnant ablation in the nuclear medicine department. The assessment tools included the following: (1) the PRISM-R2, yielding Self-Illness Separation (SIS) and Illness Perception Measure (IPM); (2) distress thermometer (DT), a measure of thyroid cancer-related distress; (3) posttraumatic growth inventory (PTGI); (4) 12-item Short-Form health survey (SF-12); and (5) the Supportive Care Needs Survey Short Form (SCNS-SF34). In addition, the content validity of PRISM-R2 was tested using the patients' comments.

RESULTS

SIS and IPM showed medium intercorrelation (r = -.482; p < 0.01), and both of them showed strongly significant associations with DT. SIS also showed significant correlations with one factor of PTGI (personal strength), four factors of SF-12 (general health, role-emotional, mental health, and vitality), and one factor of SCNS-SF34 (psychological needs). IPM showed significant correlations with five factors of SF-12 and all the factors of SCNS-SF34. No correlation was found between IPM and PTGI.

CONCLUSIONS

PRISM-R2 is a well-accepted and understandable tool to assess the psychological burden of patients with thyroid cancer in Chinese settings. It may be useful to guide or evaluate the interventions for the patients.

Psoriasis

Psoriasis is a chronic, immune-mediated disorder with cutaneous and systemic manifestations and substantial negative effects on patient quality of life. Psoriasis has a strong, albeit polygenic, genetic basis. Whereas approximately half of the accountable genetic effect of psoriasis maps to the major histocompatibility complex, >70 other loci have been identified, many of which implicate nuclear factor-κB, interferon signalling and the IL-23-IL-23 receptor axis. Psoriasis pathophysiology is characterized by abnormal keratinocyte proliferation and immune cell infiltration in the dermis and epidermis involving the innate and adaptive immune systems, with important roles for dendritic cells and T cells, among other cells. Frequent comorbidities are rheumatological and cardiovascular in nature, in particular, psoriatic arthritis. Current treatments for psoriasis include topical agents, photo-based therapies, traditional systemic drugs and biologic agents. Treatments can be used in combination or as monotherapy. Biologic therapies that target specific disease mediators have become a mainstay in the treatment of moderate-to-severe disease, whereas advances in the treatment of mild-to-moderate disease have been limited.

Assessing the Impact of Atopic Dermatitis on the Patients' Parents with the Visual Instrument 'Caregiver-PRISM'

BACKGROUND

There is a need to improve the quality of communication between clinicians and parents of young patients with atopic eczema (AE).

OBJECTIVE

To create a tool to measure the suffering that caregivers experience in association with their child's AE (Caregiver Pictorial Representation of Illness and Self-Measure, Caregiver-PRISM), assess the validity and reliability, and identify factors associated with caregiver suffering.

METHODS

Caregiver-PRISM was administered to 45 parents of patients from an AE outpatient service (Padua, Italy).

RESULTS

Caregiver-PRISM had a good test-retest reliability (r = 0.85; t7 = 4.13; p < 0.05), content validity and construct validity when used in parents of AE children. Parents with a less positive family affective climate, higher education, or with children following a diet experienced higher suffering associated with their child's AE, demonstrated by lower Caregiver-PRISM scores (p < 0.05).

CONCLUSION

Our results support the use of Caregiver-PRISM in parents of AE patients to assess suffering associated with patients' illness.
