Development and validity of the Value-based Stigma Inventory (VASI): a value-sensitive questionnaire for the assessment of mental health stigma
Ontology highlight
ABSTRACT: Background
It has been hypothesized that mental illness stigma differs according to what matters most to people, and that this results in value-based differences in stigma within societies. However, there is a lack of stigma measures that account for a broad range of values, including modern and liberal values. Methods
For the development of the Value-based Stigma Inventory (VASI) a preliminary item-pool of 68 VASI-items was assembled by mental health and stigma experts. For psychometric evaluation, we tested the VASI in an online sample of the general population (n = 4983). Results
Based on item-characteristics as well as explorative and confirmatory factor analyses, a final version of the VASI was developed, comprising 15 items and 5 subscales. The VASI shows good psychometric properties (item difficulty = 0.34 to 0.67; mean inter-item correlation r = 0.326; Cronbach’s α = 0.879). Medium to high correlations with established stigma scales (SDS, SSMI), medium associations with instruments assessing personal values (PVQ, KSA-3) and small to no associations with a social desirability scale (KSE-G) attest to good convergent and discriminatory validity of the new instrument. Normative values for the VASI subscales are presented. Conclusions
The developed VASI can be used to assess public stigma of mental illness including personal stigma-relevant value orientations. Supplementary Information

Project description:ObjectiveTo evaluate the psychometric properties and clinical utility of Chinese Multidimensional Health Assessment Questionnaire (MDHAQ-C) in patients with rheumatoid arthritis (RA) in China.Methods162 RA patients were recruited in the evaluation process. The reliability of the questionnaire was tested by internal consistency and item analysis. Convergent validity was assessed by correlations of MDHAQ-C with Health Assessment Questionnaire (HAQ), the 36-item Short-Form Health Survey (SF-36) and the Hospital anxiety and depression scales (HAD). Discriminant validity was tested in groups of patients with varied disease activities and functional classes. To evaluate the clinical values, correlations were calculated between MDHAQ-C and indices of clinical relevance and disease activity. Agreement with the Disease Activity Score (DAS28) and Clinical Disease Activity Index (CDAI) was estimated.ResultsThe Cronbach's alpha was 0.944 in the Function scale (FN) and 0.768 in the scale of psychological status (PS). The item analysis indicated all the items of FN and PS are correlated at an acceptable level. MDHAQ-C correlated with the questionnaires significantly in most scales and scores of scales differed significantly in groups of different disease activity and functional status. MDHAQ-C has moderate to high correlation with most clinical indices and high correlation with a spearman coefficient of 0.701 for DAS 28 and 0.843 for CDAI. The overall agreement of categories was satisfying.ConclusionMDHAQ-C is a reliable, valid instrument for functional measurement and a feasible, informative quantitative index for busy clinical settings in Chinese RA patients.

Project description:Fear of water is the strongest predictor for no or low swimming competencies. Some individuals will never learn to swim due to their complete avoidance of water, whereas others might have difficulty with learning due to the fact that they cannot sufficiently relax their body to facilitate floating or swimming. Therefore, it is important to identify these people and to establish effective teaching strategies that can best help this specific population. Recognizing this, there is a clear need for an assessment tool which can help swim teachers and coaches identify people with a fear of water. The study aimed to first develop and then validate a fear of water assessment questionnaire (FWAQ). 2074 male and female people participated in the creation of a 40-item questionnaire. The exploratory factor showed that a 3 factor solution including 20 items was most sensible – such a solution accounted for 31.69% of explained variance and the Cronbach’s alpha ? was 0.831, which makes for a reliable enough solution. A subsequent discriminant function analysis correctly classified 98.2% of participants. We concluded that the findings from this study support that the FWAQ is a valid scale that effectively identify people with fear of water.

Project description:IntroductionThe National Lipid Association Statin Intolerance (SI) Panel recognized the need for better understanding of the patient SI experience.ObjectiveThe objective of this research was to develop a patient-reported outcome (PRO) questionnaire to assess a patient's experience with SI.MethodsQuestionnaire development was informed via a series of research activities: literature review, concept elicitation, item generation, and content evaluation. Following the literature review and concept elicitation, a draft questionnaire was constructed and subsequently modified based on feedback from therapeutic area experts and patients via cognitive debriefing interviews.ResultsMuscle-related symptoms were the most commonly reported symptoms associated with SI in the literature review (35 of 41 articles reviewed [85%]) and in semi-structured interviews with experts (n = 5 [100%]) and patients (n = 17 of 20 [85.0%]). Physical and other impacts of SI symptoms on daily activities were also frequently reported. A 17-item draft questionnaire was created, and cognitive debriefing with experts (n = 5) and patients (n = 15) was conducted. Overall, the items, response options, and instructions were comprehensible and positively reviewed; minor changes resulted in the 15-item Statin Experience Assessment Questionnaire (SEAQ)©. Using a 30-day recall period, the SEAQ© assesses the severity and impact of six SI symptoms (muscle ache, muscle pain, muscle cramps, muscle weakness, tiredness, and joint pain) on an 11-point numeric scale. Statin discontinuation and likelihood of discontinuation due to symptoms are assessed and scored on a yes/no and five-point verbal response scale, respectively.ConclusionThe SEAQ

Project description:Objective(i) To develop the Pharmacy Value-Added Services Questionnaire (PVASQ) using emerging themes generated from interviews. (ii) To establish reliability and validity of questionnaire instrument.MethodsUsing an extended Theory of Planned Behavior as the theoretical model, face-to-face interviews generated salient beliefs of pharmacy value-added services. The PVASQ was constructed initially in English incorporating important themes and later translated into the Malay language with forward and backward translation. Intention (INT) to adopt pharmacy value-added services is predicted by attitudes (ATT), subjective norms (SN), perceived behavioral control (PBC), knowledge and expectations. Using a 7-point Likert-type scale and a dichotomous scale, test-retest reliability (N=25) was assessed by administrating the questionnaire instrument twice at an interval of one week apart. Internal consistency was measured by Cronbach's alpha and construct validity between two administrations was assessed using the kappa statistic and the intraclass correlation coefficient (ICC). Confirmatory Factor Analysis, CFA (N=410) was conducted to assess construct validity of the PVASQ.ResultsThe kappa coefficients indicate a moderate to almost perfect strength of agreement between test and retest. The ICC for all scales tested for intra-rater (test-retest) reliability was good. The overall Cronbach' s alpha (N=25) is 0.912 and 0.908 for the two time points. The result of CFA (N=410) showed most items loaded strongly and correctly into corresponding factors. Only one item was eliminated.ConclusionsThis study is the first to develop and establish the reliability and validity of the Pharmacy Value-Added Services Questionnaire instrument using the Theory of Planned Behavior as the theoretical model. The translated Malay language version of PVASQ is reliable and valid to predict Malaysian patients' intention to adopt pharmacy value-added services to collect partial medicine supply.

Project description:ObjectivesThis study aimed to develop and validate the Nurse's Workplace Mental Health Questionnaire (NWMHQ).MethodsThe questionnaire was developed based on the two continua model of mental illness and health proposed by Keyes. The initial questionnaire was generated through literature review, two rounds of Delphi expert consultation, followed by a pilot survey. Finally, the reliability and validity of the questionnaire were validated through an online survey of 2,815 registered nurses selected from the public hospitals in 11 provinces from June to July 2020.ResultsThe item-content validity index (I-CVI) of the questionnaire ranged from 0.750 to 1.000 and the average scale-level content validity index (S-CVI/Ave) was 0.906. Cronbach's α coefficient was 0.948 and test-retest reliability was 0.850. The self-rating depression scale score was negatively related to the NWMHQ score (r = -0.664, P < 0.01). The exploratory factor analysis (EFA) yielded six factors (emotional status, psychological security, positive relationship, resilience, self-efficacy, and subjective well-being), consisting of 32 items. The cumulative variance contribution rate was 65.58%. Confirmatory factor analysis (CFA) showed an acceptable fit.ConclusionThe NWMHQ developed in this study showed good reliability and validity. This questionnaire may help assess the mental health status of nurses and help nursing managers to develop appropriate targeted psychological interventions.

Project description:BackgroundEpilepsy and mental illness share similar problems in terms of stigma, as a result of centuries of superstition, ignorance and misbeliefs. Stigma leads not only to discrimination and civil and human rights violations but also to poor access to healthcare and non-adherence or decreased adherence to treatment, ultimately increasing morbidity and mortality. Despite continuous efforts in fighting stigma in these conditions, there is very limited knowledge on the phenomenon of double stigma, meaning the impact of having two stigmatised conditions at the same time.AimsTo discuss double stigma in mental health with special reference to epilepsy.MethodArticles were identified through searches in PubMed up to 31 October 2019 using the search terms 'epilepsy', 'psychiatric disorders', 'stigma' and additional material was identified from the authors' own files and from chosen bibliographies.ResultsDouble stigma is gaining attention for other stigmatised medical conditions, such as HIV, however, the literature on epilepsy is almost non-existent and this is quite astonishing given that one in three people with epilepsy have a lifetime diagnosis of a psychiatric condition. Felt (perceived) stigma and psychiatric disorders, particularly depression, create a vicious circle in epilepsy maintaining both, as depression correlates with stigma and vice versa as well as epilepsy and depression serving as bidirectional risk factors. This phenomenon has no geographical and economic boundaries as similar data have been reported for low-income and high-income countries.ConclusionsGovernments and policymakers as well as health services, patients' organisations, families and the general public need to be aware of the phenomenon of double stigma in order to develop campaigns and interventions tailored for these patients.

Project description:Background: Although the term "mental pain" is often the subject of expert opinions regarding claims for damages, there is still no standardized questionnaire in the German-speaking area to operationalize this concept. Therefore, the aim of this work is the development and validation of a self-assessment measurement for psychological pain after traumatic events (FESSTE). Methods: A first version of the questionnaire was applied on a sample of the German speaking general population (N = 425; 88% female). After performing an item analysis and exploratory factor analysis, the questionnaire was shortened and tested on a second German speaking general population sample (N = 619; 89% female). Finally, the newly developed questionnaire was related to the extent of traumatization (measured with a uniquely designed trauma checklist attached to the FESSTE) and already established instruments for the assessment of psychiatric symptom burden, which included the Brief Symptom Inventory-18 (BSI-18) and the Post-traumatic-Stress-Scale (PTSS-10). Results: The final version of the FESSTE consists of a total of 30 items and covers the subscales "Somatization," "Depression," "Intrusive Memories," "Dissociation" and "Anxiety," and a total scale "Mental Pain." Based on the confirmatory factor analysis, it is assumed that the latent factor structure of the FESSTE can be best described as a bifactor-model. The final version shows a satisfactory model fit, high internal consistencies, and strong positive correlations with the BSI-18 and PTSS-10, as well as the extent of traumatic experiences. Discussion: The FESSTE enables an operationalization of mental pain comprising five subscales and one total scale. What is more, the trauma checklist attached to the FESSTE allows for the standardized assessment of potentially traumatic experiences and the corresponding extent of these experiences. The results indicate that the FESSTE is a reliable and valid self-assessment procedure for mental pain, which is suitable for use in research and in expert practice.

Project description:PURPOSE:Stigma is a common barrier to mental health professionals (MHPs) seeking help for occupational stress and burnout, although there is a lack of psychometrically sound tools to measure this construct. The current study aimed to develop and validate a scale (the Mental Health Professional Stigma Scale; MHPSS) for this purpose. METHODS:The MHPSS and related measures were completed by 221 Australian MHPs via online survey, with a subsample completing the MHPSS again 2 weeks after initial completion. RESULTS:Exploratory factor analysis revealed a four-factor solution, comprising of 13 items and accounting for 50.16% of variance. Factors were Perceived Other Stigma, Perceived Structural Stigma, Personal Stigma, and Self stigma. The internal consistency, test-retest reliability, and validity of the scale were supported. CONCLUSIONS:The MHPSS has utility to capture stigmatising attitudes and beliefs related to occupational stress and burnout among MHPs. It may be used to assist in the development and evaluation of initiatives to reduce stigma and increase help-seeking among MHPs.

Project description:Mental illness remains as one of the most stigmatizing conditions in contemporary western societies. This study sheds light on how mental health professionals and rehabilitants perceive stigmatization. The qualitative study is based on stimulated focus group interviews conducted in five Finnish mental health rehabilitation centers that follow the Clubhouse model. The findings were analyzed through inductive content analysis. Both the mental health rehabilitants and the professionals perceived stigmatization as a phenomenon that concerns the majority of rehabilitants. However, whereas the professionals viewed stigma as something that is inflicted upon the mentally ill from the outside, the rehabilitants perceived stigma as something that the mentally ill themselves can influence by advancing their own confidence, shame management, and recovery. Improvements in treatment, along with media coverage, were seen as the factors that reduce stigmatization, but the same conceptualization did not hold for serious mental illnesses. As the average Clubhouse client was thought to be a person with serious mental illness, the rehabilitation context designed to normalize attitudes toward mental health problems was paradoxically perceived to enforce the concept of inevitable stigma. Therefore, it is important for professionals in rehabilitation communities to be reflexively aware of these tensions when supporting the rehabilitants.

Project description:BACKGROUND:Many existing scales for microstressor assessment do not differentiate between objective (ie, observable) stressor events and stressful cognitions or concerns. They often mix items assessing objective stressor events with items measuring other aspects of stress, such as perceived stressor severity, the evoked stress reaction, or further consequences on health, which may result in spurious associations in studies that include other questionnaires that measure such constructs. Most scales were developed several decades ago; therefore, modern life stressors may not be represented. Ecological momentary assessment (EMA) allows for sampling of current behaviors and experiences in real time and in the natural habitat, thereby maximizing the generalization of the findings to real-life situations (ie, ecological validity) and minimizing recall bias. However, it has not been used for the validation of microstressor questionnaires so far. OBJECTIVE:The aim is to develop a questionnaire that (1) allows for retrospective assessment of microstressors over one week, (2) focuses on objective (ie, observable) microstressors, (3) includes stressors of modern life, and (4) separates stressor occurrence from perceived stressor severity. METHODS:Cross-sectional (N=108) and longitudinal studies (N=10 and N=70) were conducted to evaluate the Mainz Inventory of Microstressors (MIMIS). In the longitudinal studies, EMA was used to compare stressor data, which was collected five times per day for 7 or 30 days with retrospective reports (end-of-day, end-of-week). Pearson correlations and multilevel modeling were used in the analyses. RESULTS:High correlations were found between end-of-week, end-of-day, and EMA data for microstressor occurrence (counts) (r?.69 for comparisons per week, r?.83 for cumulated data) and for mean perceived microstressor severity (r?.74 for comparisons per week, r?.85 for cumulated data). The end-of-week questionnaire predicted the EMA assessments sufficiently (counts: beta=.03, 95% CI .02-.03, P<.001; severity: beta=.73, 95% CI .59-.88, P<.001) and the association did not change significantly over four subsequent weeks. CONCLUSIONS:Our results provide evidence for the ecological validity of the MIMIS questionnaire.
