Abstract
OBJECTIVE This review sought to identify the experiences of persons living with genital herpes and what interventions improve the health-related quality of life of young people and adults with primary or recurrent genital herpes. INTRODUCTION Genital herpes is commonly associated with psychosocial challenges. However, a growing body of evidence suggests that its impact can be ameliorated through pharmacological and psychosocial interventions. INCLUSION CRITERIA This review considered English- and German-language studies of community-dwelling males and females, of any ethnicity and geographical location, aged 15 years and older, who had primary or recurrent genital herpes. The quantitative component of the review included studies that reported on the virus' impact on patients' health-related quality of life and/or the efficacy of interventions in improving their health-related quality of life. Studies compared antiviral suppression therapies and psychological interventions with usual care or placebo, or against one another. The qualitative component of the review included studies that investigated the perceptions and experiences of young people and adults with genital herpes. METHODS Eleven databases were searched from January 1980 to March 2020. The JBI approach to mixed methods systematic reviews was followed at each stage of the review, and a convergent segregated approach to synthesis and integration was adopted. RESULTS A total of 31 publications covering 30 studies were deemed suitable for inclusion. Studies encompassed quantitative (n = 27, across 28 publications), qualitative (n = 1), and mixed methods (n = 2) designs. Critical appraisal scores were variable, particularly among the randomized controlled trials and the analytical cross-sectional studies. All studies were included regardless of methodological quality. The quantitative components identified that depression, illness concern, stress, anxiety, isolation, stigma, and a lowering of self-esteem, self-concept, self-confidence, and health-related quality of life may be experienced by both those newly diagnosed with genital herpes and those with recurrences. It was also identified that genital herpes can have an adverse effect on work or school, sexual relationships, and relationships with friends and family. Depression was found to significantly decrease after self-hypnosis and certain psychosocial interventions. Anxiety significantly decreased following pharmacological treatment, psychosocial interventions, and hypnosis. Psychosocial interventions significantly improved mood, and a self-help module with counseling significantly improved participants' satisfaction with intimate relationships and their self-esteem. Pharmacological treatment significantly improved health-related quality of life; however, there were no significant differences between different active treatment regimens. The qualitative component of the review led to the identification of two synthesized findings: "Disclosure of a diagnosis of genital herpes poses a dilemma for people who have the virus" and "A diagnosis of genital herpes has a significant emotional impact for the individual."Integration of quantitative and qualitative evidence revealed a consensus that a diagnosis of genital herpes has a significant emotional impact for individuals and that disclosure is stressful, affects relationships, and affects health-related quality of life; however, there is a lack of consensus regarding efficacy of different interventions. CONCLUSIONS Genital herpes can lead to extreme emotional, social, relational, and sexual distress, but there is insufficient knowledge concerning which interventions best improve health-related quality of life. More high-quality research is required.

Abstract
Background There is a significant global burden of herpes simplex virus (HSV) related genital ulcer disease yet little is known about its impact on quality of life. This systematic review aimed to identify studies that quantitatively evaluated the effect of genital herpes on various aspects of health-related quality of life.
Methods Six databases were searched (MEDLINE, EMBASE, NHS Economic Evaluation Database, Health Technology Assessment, Database of Abstracts of Reviews of Effects, Web of Science Core Collection) for primary quality of life and economic evaluations of genital herpes from January 1, 2000 to January 7, 2021. Qualitative studies or those without primary data were excluded. Two authors independently extracted data from the publications. The study’s registration number with PROSPERO was CRD42021239410. Findings We identified 26 relevant publications: 19 presented primary quality of life data, and seven were economic evaluations. The primary studies presented a range of condition-specific tools for describing the quality of life in individuals with genital herpes, but only one study used a direct valuation that could be used to generate utility weights. All economic evaluations of HSV infection were from high-income country settings. Most (6 of 7) focused on neonatal HSV infection with utilities adopted from studies prior to 2000. Interpretation The extant literature on genital herpes-related quality of life is limited and requires updating. We recommend future studies be conducted in geographic- and population- diverse settings, and use preference-based condition-specific or generic-instruments to better inform economic modelling.

Abstract
Background Living with a chronic disease often means experiencing chronic treatments and regular multidisciplinary monitoring as well as a profound life-changing experience which may impact all aspects of a patients life. The patient experience of chronic disease is frequently assessed by patient reported measures (PRMs) which incorporate patients perspectives to better understand how illness, treatment and care impact the entirety of a patient’s life. The purpose of this review was to collect and review different kinds of available PRM instruments validated for chronic patients, to produce an inventory of explored concepts in these questionnaires and to identify and classify all dimensions assessing chronic patients experience. Methods A systematic review of PRM instruments validated for chronic patients was conducted from three databases (Medline, the Cochrane library, and Psycinfo). Articles were selected after a double reading and questionnaires were classified according to their targeted concept. Then, all dimensions of the questionnaires were clustered into different categories. Results 107 primary validation studies of PRM questionnaires were selected. Five kinds of instruments were recorded: 1) Questionnaires assessing health related quality of life or quality of life; 2) Instruments focusing on symptoms and functional status; 3) Instruments exploring patients’ feelings and attitude about illness; 4) Questionnaires related to patients’ experience of treatment or healthcare; 5) Instruments assessing patients attitudes about treatment or healthcare. Twelve categories of dimensions were obtained from these instruments. Conclusions This review provided an overview of some of the dimensions used to explore chronic patient experience. A large PRM diversity exists and none of the reviewed and selected questionnaires covered all identified categories of dimensions of patient experience of chronic disease. Furthermore, the definition of explored concepts varies widely among researchers and complex concepts often lack a clear definition in the reviewed articles. Before attempting to measure chronic patient experience, researchers should construct appropriate instruments focusing on well-defined concepts and dimensions encompassing patient’s personal experience, attitude and adaptation to illness, treatment or healthcare.

Abstract
Background: The quality of life of migraine patients, particularly mental domains, is severely diminished despite the preventive therapies available. We aimed to evaluate whether citalopram plus nadolol is superior to nadolol alone in terms of quality of life (QOL) in migraine patients. Methods: Adult patients with episodic migraine (≥ 3 headache days per month) were allocated by simple randomization to nadolol 40 mg daily plus citalopram 10 mg daily or to nadolol alone. Baseline visit confirmed the entry criteria and patients filled out a generic QOL (SF-36) as well a migraine-specific questionnaire (MSQoL), a measure of migraine-related disability (MIDAS), a headache calendar and Beck inventory for depression and anxiety. This battery was again completed after 16 weeks of therapy. Results: A total of 92 patients from a general neurology clinic completed the study, 85% females with migraine without aura. Fourty-four (47.83%) patients were allocated to nadolol therapy, and 48 (52.17%) to the combination of nadolol plus citalopram. After therapy, both groups had a similar gain in quality of life (SF-36 and MSQOL), but combination therapy was not superior to nadolol. Despite this improvement, all SF-36 domains remained below the population norms in both groups. Conclusion: Adding systematically citalopram 10 mg daily to a conventional migraine preventive drug (nadolol) does not result in an additional improvement in the QOL of migraine patients.

Abstract
When planning a comparative effectiveness study comparing disease-modifying treatments, competing demands influence choice of outcomes. Current practice emphasizes parsimony, although understanding multidimensional treatment impact can help to personalize medical decision-making. We discuss both sides of this 'tug of war'. We discuss the assumptions, advantages and drawbacks of composite scores and multidimensional outcomes. We describe possible solutions to the multiple comparison problem, including conceptual hierarchy distinctions, statistical approaches, 'real-world' benchmarks of effectiveness and subgroup analysis. We conclude that comparative effectiveness research should consider multiple outcome dimensions and compare different approaches that fit the individual context of study objectives.

Abstract
Health-related quality of life has not only been established as an important patient-reported outcome measure in patient care but has been defined as an evaluation criterion for therapies in the German Code of Social Law as well as in the guidelines of the American Food and Drug Administration and of the European Medicines Agency (EMA). Quality of life can be measured in a standardised manner. Validated questionnaires are available for recording specific problems of patients with, for example, skin diseases. Measuring quality of life has not yet been implemented into daily dermatological routine, although (1) studies have confirmed that the measurement of quality of life offers major benefits for the treatment of skin diseases, and (2) first experiences in implementing quality of life measurement into practice have been positive. The further implementation of systemically measuring quality of life requires advancements in automated measurement and the assumption of cost by social health insurances.

Abstract
Research in primary care medicine demonstrates that health care providers' communication varies depending on their sex, and that these sex differences in communication can influence patients' health outcomes. The present study aimed to examine the extent to which sex differences in primary care providers' communication extend to the sensitive context of gynecological care for genital herpes and whether these potential sex differences in communication influence patients' herpes transmission prevention behaviors and herpes-related quality of life. Women (N = 123) from the United States recently diagnosed with genital herpes anonymously completed established measures in which they rated (a) their health care providers' communication, (b) their herpes transmission prevention behaviors, and (c) their herpes-related quality of life. The authors found significant sex differences in health care providers' communication; this finding supports that sex differences in primary care providers' communication extend to gynecological care for herpes. Specifically, patients with female health care providers indicated that their providers engaged in more patient-centered communication and were more satisfied with their providers' communication. However, health care providers' sex did not predict women's quality of life, a finding that suggests that health care providers' sex alone is of little importance in patients' health outcomes. Patient-centered communication was significantly associated with greater quality-of-life scores and may provide a promising avenue for intervention.

Abstract
Interest in the patient's views of his or her illness and treatment has increased dramatically. However, our ability to appropriately measure such issues lags far behind the level of interest and need. Too often such measurement is considered to be a simple and trivial activity that merely requires the application of common sense. However, good quality measurement of patient-reported outcomes is a complex activity requiring considerable expertise and experience. This review considers the most important issues related to such measurement in the context of chronic disease and details how instruments should be developed, validated and adapted for use in additional languages. While there is often consensus on how best to undertake these activities, there is generally little evidence to support such accord. The present article questions these orthodox views and suggests alternative approaches that have been shown to be effective.

Abstract
This study investigated the psychosocial factors that influence psychological adjustment among women with genital herpes, while taking into account the physical factors. Women with herpes (N = 105, age 18-30) completed an on-line survey about factors related to their diagnosis and herpes-related quality of life. Perceived stigma, acceptance coping, denial coping, support from the Internet, and support from religious/spiritual figures accounted for 65.9 percent of the variance in quality of life scores. The findings reveal the importance of specific coping strategies and sources of support on psychological adjustment to herpes. Furthermore, a significant interaction between stigma and acceptance coping suggests a complex relationship between these two psychosocial factors that warrants future research.

Abstract
OBJECTIVE To assess the psychosocial well-being and quality of life among women with a new genital herpes simplex virus diagnosis. DESIGN Data were collected by a cross-sectional survey. PARTICIPANTS Eighty-three women diagnosed with genital herpes simplex virus by culture, visual exam and/or a description of symptoms within the last 3 months were recruited from primary health care clinics by their provider. MEASURES Participants completed the Hospital Anxiety and Depression Scale and the Recurrent Genital Herpes Quality of Life scale. RESULTS Thirty-four percent of the women qualified as "clinical cases" for depression, and 64% were designated as "anxiety cases" based on Hospital Anxiety and Depression Scale scoring methods. A majority of participants reported feeling ashamed about having herpes and worried about having an outbreak or giving herpes to someone else. CONCLUSIONS Despite substantial progress toward understanding genital herpes simplex virus epidemiology and transmission, a diagnosis of genital herpes continues to cause considerable psychosocial morbidity and to impact quality of life. There is a dearth of good evidence on how best to intervene to minimize the psychological impact of a diagnosis. Experts recommend addressing both the medical and psychological aspects of infection by providing antiviral therapy, written material, and resources.

Abstract
OBJECTIVE The Herpes Outbreak Impact Questionnaire (HOIQ) and Herpes Symptom Checklist (HSC) are patient-completed questionnaires for assessing genital herpes outbreaks. This report describes the validation of paper-and-pencil versions of the scales and responsiveness assessments in an Australian clinical trial. METHODS Acceptability of the language of the original UK versions was tested with Australians. The HOIQ and HSC were then field-tested with patients. The new versions were validated using patients' daily responses to the questionnaires in a famciclovir study. RESULTS The HOIQ and HSC were readily adapted into Australian English and were acceptable to patients. Psychometric sample: N = 151; 81 (54%) male; mean age 39.9 +/- 11.6 years; mean outbreaks 5.1 +/- 3.0 per year. Internal consistency was good (alphas at outbreak 1 ranged 0.84-0.90 HOIQ and 0.73-0.87 HSC). Rasch analysis showed item stability over time. Correlations between HOIQ and HSC ranged from 0.46 to 0.60. Both scales distinguished outbreak healing presence or absence at day 6 (P = 0.001), and the HOIQ scale distinguished between symptom severity groups (P < 0.001). Scale scores declined significantly over study duration, exhibiting large effect sizes. CONCLUSIONS The paper-and-pencil HOIQ and HSC were reliable, valid, and responsive in a clinical trial setting. These instruments are recommended for use in clinical studies.

Abstract
OBJECTIVE To develop measures of the day-to-day symptomatic and functional impact of recurrent genital herpes (RGH) outbreaks. The Herpes Outbreak Impact Questionnaire (HOIQ) and the Herpes Symptom Checklist (HSC) were designed to be acceptable to clinical professionals and to reflect patients' experience. METHODS Scale content was derived via literature review and interviews with RGH patients and physicians. Questionnaires were assessed for face/content validity in the UK and the language checked for acceptability in the United States. The US measures were assessed for face/content validity with patients. Scaling/psychometric properties were determined via web survey. Participants completed the questionnaires twice during an outbreak, with 24 to 72 hours between administrations. RESULTS Respondents found the questionnaires relevant and easy to understand and complete. Application of Rasch analysis resulted in the removal of two HOIQ items. Both scales were found to be unidimensional. Item stability testing for the HOIQ indicated that the measure is reproducible. Internal consistency was good (alpha: time 1 = 0.87, time 2 = 0.91). Discriminative validity was demonstrated by the measure's ability to distinguish between individuals who differed by self-reported severity of outbreak. The HOIQ and HSC were both responsive to change over time. CONCLUSIONS The HSC and the HOIQ can determine the impact of a herpes outbreak effectively. They are designed to be used daily during such outbreaks and to determine the effectiveness of RGH treatment.

Quality of life in infants and children with atopic dermatitis: addressing issues of differential item functioning across countries in multinational clinical trials. Health Qual Life Outcomes 2007; 5:45. [PMID: 17662129 PMCID: PMC1994672 DOI: 10.1186/1477-7525-5-45] [Citation(s) in RCA: 32] [Impact Index Per Article: 1.9] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/14/2007] [Accepted: 07/27/2007] [Indexed: 11/26/2022] Open
Abstract
Background A previous study had identified 45 items assessing the impact of atopic dermatitis (AD) on the whole family. From these it was intended to develop two separate scales, one assessing impact on carers and the other determining the effect on the child. Methods The 45 items were included in three clinical trials designed to test the efficacy of a new topical treatment (pimecrolimus, Elidel cream 1%) in the treatment of AD in infants and children and in validation studies in the UK, US, Germany, France and the Netherlands. Rasch analyses were undertaken to determine whether an internationally valid, unidimensional scale could be developed that would inform on the direct impact of AD on the child. Results Rasch analyses applied to the data from the trials indicated that the draft measure consisted of two scales, one assessing the QoL of the carer and the other (consisting of 12 items) measuring the impact of AD on the child. Three of the 12 potential items failed to fit the measurement model in Europe and five in the US. In addition, four items exhibiting differential item functioning (DIF) by country were identified. After removing the misfitting items and controlling for DIF it was possible to derive a scale; The Childhood Impact of Atopic Dermatitis (CIAD) with good item fit for each trial analysis. Analysis of the validation data from each of the different countries confirmed that the CIAD had adequate internal consistency, reproducibility and construct validity. The CIAD demonstrated the benefits of treatment with Elidel over placebo in the European trial. A similar (non-significant) trend was found for the US trials. Conclusion The study represents a novel method of dealing with the problem of DIF associated with different cultures. Such problems are likely to arise in any multinational study involving patient-reported outcome measures, as items in the scales are likely to be valued differently in different cultures. However, where all items in a scale fit both a single theoretical construct and the Rasch measurement model, it is feasible to conceive of outcome measures with a different set of items in each language.

Abstract
Preventive therapy is aimed at reducing migraine frequency, but should also improve the much deteriorated quality of life of the migraneur. We aimed to evaluate the impact of preventive therapy with two widely employed drugs (topiramate and nadolol) on the quality of life of migraine patients. A population of consecutive migraineurs aged > or = 16 years, with frequent migraines, was selected prospectively for evaluation at baseline and after 16 weeks of therapy with nadolol or topiramate (40 mg and 100 mg daily, respectively) by generic and specific quality of life questionnaires (SF-36 and MSQOL) and by an anxiety and depression scale (HADS). Preventive therapy resulted in a statistically significant improvement in physical domains of the SF-36, whereas mental domains remained almost unchanged. Despite this improvement, all domains remained below the population norms. The HADS revealed a moderate depressive state at baseline that did not change with therapy. The MSQOL global score also revealed statistically significant improvement. Both drugs were similarly effective, although topiramate was superior on the role physical domain compared with nadolol. Preventive therapy with nadolol and topiramate significantly improves the quality of life of migraineurs, although additional efforts are needed to place them in a nearer-to-normal situation compared with the general population.

Abstract
BACKGROUND Suppressive therapy has not been studied during the first year after acquisition of genital herpes, the time of maximum frequency of reactivation, potential for transmission, and impact on quality of life. OBJECTIVE The objective of this study was to evaluate the effectiveness of suppressive therapy with valacyclovir initiated within 3 months of infection. STUDY DESIGN The authors conducted a double-blind, randomized, controlled trial of 1.0 g valacyclovir daily versus placebo for 6 months in 119 patients. RESULTS Herpes simplex virus (HSV) type 2 and HSV-1 were documented in 75 and 22 patients, respectively. In intention-to-treat analysis, annualized rates of symptomatic recurrences for valacyclovir and placebo, respectively, were 1.7 +/- 2.7 (mean +/- standard deviation) and 3.4 +/- 4.0 outbreaks per year (P = 0.012). Time to first recurrence was 80 +/- 47 days for valacyclovir and 54 +/- 49 days for placebo (P = 0.001). The differences in favor of valacyclovir were greatest in patients with confirmed HSV-2 infection. The Recurrent Genital Herpes Quality of Life score in HSV-2 infected patients rose 11.9 +/- 11.1 points for valacyclovir and 5.9 +/- 9.1 points for placebo (P = 0.040). CONCLUSIONS Early suppressive therapy with valacyclovir reduces symptomatic recurrent outbreaks, especially in patients with HSV-2 infection. Valacyclovir therapy was associated with improved herpes-related quality of life.

Abstract
OBJECTIVES We conducted this study to compare episodic and suppressive therapy for genital herpes about disease characteristics, disease burden, and psychologic impact. STUDY DESIGN The authors conducted a randomized, open-label, 1-year treatment trial. RESULTS Forty subjects were randomized to episodic therapy with valacyclovir (500 mg twice daily for 5 days) and 40 to suppressive therapy (500 mg daily). Subjects in the episodic arm experienced more outbreaks (7.87 +/- 4.65) than those in the suppressive arm (1.59 +/- 1.93) (P <0.001). Subjects in the episodic arm also had significantly more days with pain and lesions (6.5 +/- 7.3) than those in the suppressive arm (1.1 +/- 3.3) (P < 0.001), and other quantitative measures of disease burden also favored the suppressive arm. Both treatment groups had significant improvements in their recurrent genital herpes quality-of-life scores from baseline that persisted throughout the study; however, there was no significant difference between the treatment arms in these scores. CONCLUSIONS Suppressive therapy of recurrent genital herpes with valacyclovir has a greater impact on measures of disease frequency and burden than episodic therapy. However, both treatment strategies lead to significant improvements in recurrent genital herpes quality-of-life scores. Both treatment strategies benefit patients with recurrent genital herpes.

Abstract
Background The Ankylosing Spondylitis Quality of Life (ASQOL) questionnaire is a unidimensional, disease-specific measure developed in the UK and the Netherlands. This study describes its adaptation into other languages. Methods The UK English ASQOL was translated into US English; Canadian French and English; French; German; Italian; Spanish; and Swedish (dual-panel methods). Cognitive debriefing interviews were conducted with AS patients. Psychometric/scaling properties were assessed using data from two Phase III studies of adalimumab. Baseline and Week-2 data were used to assess test-retest reliability. Validity was determined by correlation of ASQOL with SF-36 and BASFI and by discriminative ability of ASQOL based on disease severity. Item response theory (Rasch model) was used to test ASQOL's scaling properties. Results Cognitive debriefing showed the new ASQOL versions to be clear, relevant and comprehensive. Sample sizes varied, but were sufficient for: psychometric/scaling assessment for US English and Canadian English; psychometric but not scaling analyses for German; and preliminary evidence of these properties for the remaining languages. Test-retest reliability and Cronbach's alpha coefficients were high: US English (0.85, 0.85), Canadian English (0.87, 0.86), and German (0.77, 0.79). Correlations of ASQOL with SF-36 and BASFI for US English, Canadian English, and German measures were moderate, but ASQOL discriminated between patients based on perceived disease severities (p < 0.01). Results were comparable for the other languages. US English and Canadian English exhibited fit to the Rasch model (non-significant p-values: 0.54, 0.68), confirming unidimensionality. Conclusion The ASQOL was successfully translated into all eight languages. Psychometric properties were excellent for US English, Canadian English, and German, and extremely promising for the other languages.

Abstract
OBJECTIVE To produce and evaluate the official Swedish language version of the Rheumatoid Arthritis Quality of Life instrument (RAQoL). METHODS The UK RAQoL was translated into Swedish by a bilingual translation panel. A separate lay panel was conducted to consider the appropriateness and comprehensibility of the items in Swedish. Interviews were conducted with 15 Swedish RA patients to assess face and content validity. Responses to a postal survey were used to calculate reproducibility and construct validity. RESULTS Few difficulties arose in the translation process and the new language version was well received by the lay panel and field-test participants. One hundred and sixty-five RA patients participated in the postal survey (69% female; mean age 62.7 years, SD 11.3, RA duration range 1-62 years). Cronbach's alpha for the Swedish RAQoL was 0.91 and test-retest reliability was 0.95, indicating that the instrument has adequate inter-relatedness of items and very low inherent random measurement error. A high correlation with the Health Assessment Questionnaire (HAQ) was observed; this was expected because RA has significant physical manifestations that are in turn a significant determinant of QoL. The Swedish RAQoL was able to distinguish between patients who differed according to their self-perceived RA severity, general health, and rating of their RA today, in addition to whether or not the patient was experiencing a flare of RA. CONCLUSIONS The official Swedish RAQoL was well received by RA patients. The psychometric quality of the adapted questionnaire means that it is suitable for inclusion in clinical trials involving patients with RA.

Abstract
OBJECTIVE No outcome measures specific to pulmonary hypertension (PH) currently exist. The aim of the study was to develop health-related quality of life (symptoms and functioning) scales and a quality of life scale that would allow comprehensive, accurate and valid patient-reported outcome assessment in clinical studies. METHODS The content of the Cambridge Pulmonary Hypertension Outcome Review (CAMPHOR) was derived from qualitative interviews conducted with 35 patients. Item reduction was based on the analysis of responses to a postal survey (n=75) and patient interviews (n=15) designed to determine face and content validity. A final postal validation study (n=91) was performed to determine reproducibility and construct validity. RESULTS The questionnaire was well received by participants who found it to be relevant, comprehensible and quick and easy to complete. Rasch and factor analyses were conducted to ensure unidimensionality of the final CAMPHOR scales; Overall symptoms (made up of Energy, Breathlessness and Mood subscales), Functioning and Quality of life. The CAMPHOR scales had good internal consistency (alpha=0.90-0.92) and reproducibility (test-retest correlations=0.86-0.92). They also exhibited convergent, divergent and known groups validity. CONCLUSIONS The CAMPHOR is a valuable new instrument for assessing patient-reported outcome in PH clinical trials and routine practice.

Abstract
BACKGROUND Several instruments are available for assessing impairment and disability associated with psoriasis. The first true psoriasis-specific quality of life (QoL) questionnaire suitable for use in clinical trials, the Psoriasis Index of Quality of Life (PSORIQoL), has recently been developed in the UK. The aim of the current study was to produce and validate a conceptually equivalent US version of the PSORIQoL with equally good psychometric properties. METHODS A lay translation panel was employed to ensure that the wording of the questionnaire was appropriate for a US population. Semi-structured interviews conducted with 37 patients tested the instrument's ease of completion, relevance and comprehensiveness. Finally, a test-retest validation mail survey was conducted with 72 patients to determine reliability, internal consistency and construct validity. RESULTS Few changes were necessary to the wording of the questionnaire. Interviewees found the questionnaire easy to complete (requiring an average of 4 min) and the content relevant and comprehensive. The adapted measure had comparable psychometric properties to the original, with a test-retest reliability coefficient of 0.90, indicating excellent reproducibility. Internal consistency and initial indications of construct validity were also good, with scores on the measure related as expected to perceived general health and severity of psoriasis and the presence of visible lesions. CONCLUSIONS The US PSORIQoL is a practical, reliable and valid instrument for measuring the impact of psoriasis and its treatment on QoL in clinical trials and in routine practice. It remains necessary to establish the instrument's responsiveness to changes in QoL associated with effective interventions.

Abstract
Health related quality of life (HRQOL) indicators take into account the personal perception of health, and are proposed as an alternative for efficacy indicators in medical and therapeutic decision-making. They provide, after elaboration and validation of a questionnaire, a standardized assessment of the health status perception. The authors had for aim to review of a variety of HRQOL instruments developed for patients presenting with genital herpes infection. Generic instruments are designed to be applicable in general population and disease-targeted instrument are potentially more sensitive to the characteristics of a specific population. Among HRQOL instruments, we found 4 specific disease-targeted questionnaires developed for patients presenting with genital herpes infection: Genital herpes questionnaire, Herpes research center questionnaire, quality of life with herpes (QLH) scale, and recurrent genital herpes quality of life (RGHQoL).

Abstract
Genital herpes is a common, chronic, recurrent, viral sexually transmitted infection (STI) occurring worldwide. The first episode may be severe and prolonged, but most recurrences are usually short lived and minor. Although most individuals with this infection have no symptoms, STIs, including genital herpes, often cause psychological and psychosexual morbidity. Unfortunately, the existing data on the psychological symptoms associated with genital herpes have many limitations, including anecdotal reporting, evaluation of small and selected populations, use of varied and sometimes unevaluated questionnaires, and lack of controls. Some individuals with recurrent genital herpes display a range of emotional responses, including depression, anguish, distress, anger, diminution of self-esteem and hostility towards the person believed to be the source of infection. However, it is always important to consider the possibility of pre-existing psychopathology. Several retrospective studies have suggested that stress could lead to recurrences of genital herpes infection. However, prospective studies have been unable to demonstrate any relationship between pre-existing stress and recurrences. What these studies were able to demonstrate was that stress and recurrences occurred simultaneously, suggesting that perhaps it was the recurrences that were causing stress, rather than the reverse.

Abstract
BACKGROUND Genital herpes (GH) is a common sexually transmitted infection. Novel tools for the control of GH (for example, tests and vaccines) are emerging, but optimal assessment of the cost effectiveness of such interventions requires scaled, preference based estimates of the impact of GH on health related quality of life. METHODS We provided self administered interviews to 39 individuals with recurrent GH recruited from an STD clinic and a GH support group in southern Ontario, Canada. Health preference estimates were generated using visual analogue scales (VAS), a time-tradeoff approach (TTO) and the Health Utilities Index Mark-II (HUI-II). Quality of life was also assessed with the Recurrent Genital Herpes Quality of Life scale (RGHQoL). RESULTS Average (SD) health values for asymptomatic and symptomatic genital herpes were 0.89 (0.21) and 0.89 (0.22) using TTO, and 0.76 (0.30) and 0.71 (0.30) using VAS. Health utility estimates generated with HUI-II for transient symptomatic and asymptomatic health states were 0.93 (0.08) and 0.80 (0.16). Log transformed health value estimates exhibited convergent validity when compared to RGHQoL, as did health utility estimates for symptomatic GH. Utility scores for symptomatic GH increased (improved) with increasing age; no other subject characteristic was predictive of preference weights. CONCLUSIONS Preference based measures of health related quality of life can be elicited with relative ease in the context of genital herpes, and preference weights are correlated with quality of life scores generated using the RGHQoL. Generation of preference weights will permit direct comparison of the economic attractiveness of herpes prevention interventions with that of other commonly available health interventions.

Abstract
Several years experience has now been gained in the use of needs-based measures in clinical trials and such use is increasing rapidly. This paper shows how four needs-based quality of life (QoL) instruments have proved effective in determining the benefits of interventions from the patients' perspective in clinical studies and trials. The instruments discussed are; the Quality of Life in Depression Scale (QLDS), the Migraine Specific Quality of Life Scale (MSQoL), the Recurrent Genital Herpes Quality of Life (RGHQoL), and the Quality of life-Assessment in Growth Hormone Deficient Adults (QoL-AGHDA).

Abstract
This paper discusses recent advances that have been made in the field of psychometrics, specifically, the application of Rasch analysis to the instrument development process. It emphasizes the importance of assessing the fundamental scaling properties of an instrument prior to consideration of traditional psychometric indicators. The paper introduces Rasch analysis and shows how it has been applied in the development of needs-based measures in order to ensure that they provide unidimensional measurement. By ensuring that scales are based on the same measurement model and that they fit the Rasch model it is possible for QoL scores to be compared across diseases by means of cocalibration and item banking.

Abstract
Due to the international nature of many clinical studies and trials it is often necessary to produce several language versions of specific measures. While it is generally acknowledged that it is necessary to produce versions that are conceptually equivalent, the best method of achieving this is more controversial. It is commonly stated that there is a gold-standard method, which involves forward and backward translation. However, no evidence has been presented to support this view. This paper argues that the "gold-standard" method is difficult to support and describes an alternative method involving dual translation panels that has been used in the production of all adaptations of needs-based quality of life instruments.

Abstract
The ability to produce high quality instruments for the assessment of quality of life has advanced considerably in recent years. As the science progresses it has become clear that certain standards must be met if outcome measures are to be capable of providing useful, reliable, and valid information within the context of clinical studies and trials. This paper specifies what these standards are with particular reference to theoretical basis, practicality, acceptability to respondents, unidimensionality, scaling and psychometric properties, and cultural validity and equivalence. The paper also indicates how failure to achieve such standards results in measures that are inaccurate and insensitive to true changes in outcome.

Abstract
BACKGROUND Patient reported outcome measures used in studies of psoriatic arthritis (PsA) have been found to be inadequate for determining the impact of the disease from the patient's perspective. OBJECTIVE To produce the PsAQoL, a PsA-specific quality of life (QoL) instrument, employing the needs based model of QoL that would be relevant and acceptable to respondents, valid, and reliable. METHODS Content was derived from qualitative interviews conducted with patients with PsA. Face and content validity were assessed by field test interviews with a new sample of patients with PsA. A postal survey was conducted to improve the scaling properties of the new measure. Finally, a test-retest postal survey was used to identify the final measure and to test its scaling properties, reliability, internal consistency, and validity. RESULTS Analysis of the qualitative interview transcripts identified a 51 item questionnaire. Field test interviews confirmed the acceptability and relevance of the measure. Analysis of data from the first postal survey (n = 94) reduced the questionnaire to 35 items. Rasch analysis of data from the test-retest survey (n = 286) identified a 20 item version of the PsAQoL with good item fit. This version had excellent internal consistency (alpha = 0.91), test-retest reliability (0.89), and validity. CONCLUSIONS The PsAQoL is a valuable tool for assessing the impact of interventions for PsA in clinical studies and trials. It is well accepted by patients, taking about three minutes to complete, is easy to administer, and has excellent scaling and psychometric properties.

Abstract
BACKGROUND Patients with psoriasis have significant impairment in their quality of life (QoL). Several patient-completed instruments are available to measure outcome in dermatological conditions but these primarily focus on severity of disease rather than on QoL. OBJECTIVES To develop a new instrument specifically designed to measure QoL in psoriasis-the Psoriasis Index of Quality of Life (PSORIQoL). METHODS The content of the instrument was derived from qualitative interviews with 62 psoriasis patients in the U.K., Italy and the Netherlands. Content analysis of the interview transcripts from the three countries identified potential items for the questionnaire. All further stages of the project were conducted in the U.K. only. Face and content validity were determined by means of a focus group held with seven psoriasis patients and face-to-face interviews with a further 21 patients. A new draft version of the PSORIQoL, together with the Dermatology Life Quality Index (DLQI) and the General Well-Being Index (GWBI), were completed by a new sample of psoriasis patients contacted by mail, in order to determine construct validity. A subsample of the respondents completed a similar package 2 weeks later, to assess reproducibility (reliability). RESULTS The first version of the PSORIQoL consisted of 61 items covering the needs identified in the interviews as having been affected by psoriasis or its treatment. These included fear of negative reactions from others, self-consciousness and poor self-confidence, problems with socialization, physical contact and intimacy, limitations on personal freedom and impaired relaxation, sleep and emotional stability. Following the focus group and field-test interviews, a new draft measure consisting of 45 items was completed by 148 patients, 88 of whom completed and returned a similar package 2 weeks later. Application of Rasch analysis identified a final 25-item version of the PSORIQoL. This version had a test-retest reliability coefficient of 0.89, indicating good reproducibility. The levels of association with the DLQI and PGWB indicated that the PSORIQoL measures a related but distinct construct. CONCLUSIONS The PSORIQoL appears to be a practical, reliable and valid instrument for measuring the impact of psoriasis on QoL. It remains necessary to establish the instrument's responsiveness to changes in QoL associated with treatment.

Abstract
BACKGROUND Valacyclovir is effective for suppressive and episodic treatment of recurrent genital herpes. Few data on patients' treatment strategy preferences are available. GOAL The goal was to assess patients' preference, satisfaction, and quality of life with suppressive versus episodic treatment of recurrent genital herpes. STUDY DESIGN This was a multicenter, open-label, randomized, two-arm, crossover 48-week study involving 225 patients with genital herpes. RESULTS Suppressive valacyclovir therapy was preferred to episodic valacyclovir treatment by 72% of patients (P < 0.001). Overall treatment satisfaction and quality of life were significantly greater during suppressive therapy (P < 0.001 and P = 0.002, respectively). The risk of recurrence during the first 24 weeks was reduced by 78% with suppressive therapy (P < 0.001). Significantly fewer patients experienced recurrences during suppressive treatment than with episodic treatment (P < 0.001). Valacyclovir was well tolerated. CONCLUSIONS Suppressive valacyclovir was preferred to episodic therapy by most patients. Suppressive therapy was associated with increased treatment satisfaction, and decreased risk and lower frequency of recurrences.

Abstract
BACKGROUND Although disease-specific health status measures are available for ankylosing spondylitis (AS), no instrument exists for assessing quality of life (QoL) in the condition. OBJECTIVE To produce an AS-specific QoL measure that would be relevant and acceptable to respondents, valid, and reliable. METHODS The ASQoL employs the needs-based model of QoL and was developed in parallel in the UK and the Netherlands (NL). Content was derived from interviews with patients in each country. Face and content validity were assessed through patient field test interviews (UK and NL). A postal survey in the UK produced a more efficient version of the ASQoL, which was tested for scaling properties, reliability, internal consistency, and validity in a further postal survey in each country. RESULTS A 41 item questionnaire was derived from interview transcripts. Field testing interviews confirmed acceptability. Rasch analysis of data from the first survey (n=121) produced a 26 item questionnaire. Rasch analysis of data from the second survey (UK: n=164; NL: n=154) showed some item misfit, but showed that items formed a hierarchical order and were stable over time. Problematic items were removed giving an 18 item scale. Both language versions had excellent internal consistency (alpha=0.89-0.91), test-retest reliability (r(s)=0.92 UK and r(s)=0.91 NL), and validity. CONCLUSIONS The ASQoL provides a valuable tool for assessing the impact of interventions for AS and for evaluating models of service delivery. It is well accepted by patients, taking about four minutes to complete, and has excellent scaling and psychometric properties.

Abstract
Herpes genitalis is one of the most common viral sexually transmitted diseases in the world, with an estimated seroprevalence in the US of greater than 20%. Two viruses of the same family cause herpes genitalis: herpes simplex virus 1 and 2. After the resolution of primary infection, the virus persists in the nerve roots of the sacral plexus, often causing recurrent (though generally less severe) outbreaks. These outbreaks, as well as the infectious potential to the patient's sexual partners, results in significant psychological stress on the patient, and has a tremendous negative impact on QOL. Current treatment modalities may result in a reduction in the number of outbreaks and viral shedding, but no cure exists. Although studies have clearly demonstrated the negative impact of recurrent genital herpes on QOL, an assessment scale specific to herpes was not developed until recently. Earlier studies indicated that patients did not perceive a significant benefit from episodic treatment with antivirals, but studies using the Recurrent Genital Herpes Quality of Life Questionnaire (RGHQoL) have now demonstrated that suppressive antiviral therapy improves quality of life in patients with frequent recurrences of genital herpes. However, not all patients with recurrent genital herpes need suppressive therapy, and proposed factors to consider include frequency of recurrence, physical and psychological distress caused by recurrences, and the potential for transmission to the patient's sexual partner. Newer therapeutic modalities, including the topical immune response modifier resiquimod and herpes vaccines, may eventually be shown to further decrease the psychological morbidity of recurrent genital herpes.

Abstract
Genital herpes simplex virus infections are widespread throughout the world and are characterized by stigma, myth, and anxiety by patients and the public but are perceived as trivial by most physicians. Surveys in the United States, Europe, Australia, and South Africa have measured the unfavorable effect of genital herpes on infected patients, health care resources, and workplace productivity. These surveys identified limited satisfaction of patients with current care and support (41% satisfied), although satisfaction scores were greater for patients receiving suppressive antiviral therapy (56% satisfied). Bridging the gap between patients and physicians is vital for improving the management of genital herpes. Key to facilitating patient-physician partnerships is education and recognition by physicians that patients with genital herpes may have expert knowledge. In effective partnerships, physicians and patients can have informed constructive discussions such that patients share in the responsibility for managing their disease and in therapeutic decision making.

Abstract
OBJECTIVE To investigate whether suppressive antiviral therapy improves health related quality of life in patients with recurrent genital herpes. METHODS Health related quality of life was measured using the disease specific recurrent genital herpes quality of life questionnaire (RGHQoL) as part of a randomized, double blind, 52 week, placebo controlled, dose ranging study of once and twice daily valaciclovir or aciclovir for the suppression of recurrent genital herpes in patients with six or more recurrences per year. RESULTS Of 1479 participants, 1349 patients completed the baseline questionnaire. There were no significant baseline differences in RGHQoL score between any of the treatment groups. After 3 months there were significantly greater improvements in mean RGHQoL scores for all active treatment groups compared with placebo (p < 0.05). Mean RGHQoL score improvements from baseline remained significantly higher in the active treatment groups than in the placebo group after 6 and 12 months, indicating that the improved health related quality of life in patients receiving suppressive antiviral therapy was sustained over a prolonged period of time. CONCLUSION Suppressive antiviral therapy is an effective strategy for improving the quality of life of patients with recurrent genital herpes. These improvements in quality of life are sustained over time, thus enhancing the clinical benefit in the long term management of this condition.
