Perception of Multiple Sclerosis Impact and Treatment Efficacy Beliefs: Mediating Effect of Patient's Illness and Self-Appraisals

Perceived illness-related uncertainty among patients with mid-stage relapsing-remitting multiple sclerosis

BACKGROUND

Patients with multiple sclerosis (MS) have to deal with a variable disease trajectory often associated with disability and productivity loss.

OBJECTIVE

This study aimed to assess illness-related uncertainty and associated correlates in patients with relapsing-remitting multiple sclerosis (RRMS) beyond the near diagnosis phase.

METHODS

We conducted a multicenter, non-interventional study including patients diagnosed with RRMS (2017 revised McDonald criteria) and a disease duration of 3 to 8 years. Perceived uncertainty was measured using the Mishel Uncertainty of Illness Scale (MUIS). Associations between the MUIS and different patient-based outcome measures were analyzed using Spearman's rank correlation.

RESULTS

A total of 201 patients were studied (mean age (standard deviation): 38.7 (8.4) years, 71.4 % female). The median disease duration (interquartile range) was 6.0 (4.0-7.0) years and the median EDSS score was 1.0 (0.0-2.0). The mean MUIS score was 38.2 (10.8). Perceived uncertainty was positively correlated with fatigue (p < 0.001), symptom severity (p < 0.001), anxiety (p < 0.001), depressive symptoms (p < 0.001), and a threatening illness perception (p < 0.001), and negatively correlated with self-management (p < 0.001), self-efficacy (p < 0.001), processing speed (p < 0.001), knowledge of MS (p = 0.006), and quality of life (p < 0.001).

CONCLUSION

Illness-related uncertainty was common in a population of mid-stage RRMS. Identifying uncertainty and its associated factors may be useful for implementing preventive strategies to help patients cope with the disease throughout life.

Hopelessness in Patients with Early-Stage Relapsing-Remitting Multiple Sclerosis

Background

Hopelessness is a risk factor for depression and suicide. There is little information on this phenomenon among patients with relapsing-remitting multiple sclerosis (RRMS), one of the most common causes of disability and loss of autonomy in young adults. The aim of this study was to assess state hopelessness and its associated factors in early-stage RRMS.

Methods

A multicenter, non-interventional study was conducted. Adult patients with a diagnosis of RRMS, a disease duration ≤ 3 years, and an Expanded Disability Status Scale (EDSS) score of 0-5.5 were included. The State-Trait Hopelessness Scale (STHS) was used to measure patients´ hopelessness. A battery of patient-reported and clinician-rated measurements was used to assess clinical status. A multivariate logistic regression analysis was conducted to determine the association between patients' characteristics and state hopelessness.

Results

A total of 189 patients were included. Mean age (standard deviation-SD) was 36.1 (9.4) years and 71.4% were female. Median disease duration (interquartile range-IQR) was 1.4 (0.7, 2.1) years. Symptom severity and disability were low with a median EDSS (IQR) score of 1.0 (0, 2.0). A proportion of 65.6% (n=124) of patients reported moderate-to-severe hopelessness. Hopelessness was associated with older age (p=0.035), depressive symptoms (p=<0.001), a threatening illness perception (p=0.001), and psychological and cognitive barriers to workplace performance (p=0.029) in the multivariate analysis after adjustment for confounders.

Conclusion

Hopelessness was a common phenomenon in early-stage RRMS, even in a population with low physical disability. Identifying factors associated with hopelessness may be critical for implementing preventive strategies helping patients to adapt to the new situation and cope with the disease in the long term.

Sexual Dysfunction in People with Multiple Sclerosis: The Role of Disease Severity, Illness Perception, and Depression

Despite being a common issue in people with multiple sclerosis (pwMS), sexual dysfunction is still underinvestigated. This work aims to assess the potential determinants of sexual dysfunction in pwMS by considering its relationship with disease severity (in terms of global disability), illness perception, and depressive symptoms. In this multicenter study, 1010 pwMS responded to an online survey. A serial mediation model considering negative illness perception and depressive symptoms as mediators of the relationship between disease severity and sexual dysfunction was conducted using the SPSS PROCESS Macro with bias-corrected bootstrapping (5000 samples). Disease severity exerts an indirect effect on sexual dysfunction via illness perception, both independently and through depressive symptoms. However, the results indicated that illness perception plays a more crucial role in sexual dysfunction in pwMS with mild disability than in pwMS with moderate-severe disability. This study suggests that higher disability increases its magnitude by enhancing negative illness perception, that, in turn, affects sexual dysfunction both directly and through depressive symptoms, especially in pwMS with mild disability. Modulating the effect of illness perception by favoring adaptive coping strategies might represent a valid approach to mitigate sexual dysfunction symptoms in MS.

Alternative medicine therapies in neurological disorders: Prevalence, reasons and associated factors. A systematic review

OBJECTIVE

This systematic review aimed to identify the prevalence of CAM use in patients with neurological disorders, and also to know most frequent types of CAM used.

METHODS

Five databases: PubMed, Science Direct, EBSCO, Latindex and Scielo (in English and Spanish) were searched from January 2010 to May 2021. Only original cross-sectional, retrospective and cohort studies were included, whose primary objective was to describe the frequency of CAM use in neurological disorders and/or the related factors to its use in adults. Based on the data, a descriptive analysis was performed, covering the characteristics of studies, measuring methods, prevalence, types and related factors. To control the risk of bias, a quality assessment of each study was performed using STROBE checklist.

RESULTS

For the final analysis, 40 studies were included. Most common pathologies observed in the studies were multiple sclerosis, headache, stroke, Parkinson and epilepsy. The STROBE score of studies ranged from 13 to 22 points, with an average of 18.2. Prevalence of CAM use was highly variable from one study to another (16% in stroke patients, to 100% in amyotrophic lateral sclerosis or spinal cord injury patients). Biological therapies (dietary supplements and herbal medicine) were the most commonly CAM types used. The associated factors identified were female sex, an age between 40 and 50 years, and higher socioeconomic level. Not all studies investigated about the results of CAMs but these ranged from 35% to more than 80% of reporting positive effects.

CONCLUSIONS

The prevalence of CAM use in neurological diseases is highly variable (16%-100%); the most used type of CAM was biological therapies and the associated factors were female sex, age between 40 and 50 years old and high socioeconomic level.

Illness perceptions and outcome in multiple sclerosis: A systematic review of the literature

According to Leventhal's self-regulation model, ill people construct personal representations of their disease, namely illness perceptions, which impact their coping strategies and the emotional response to their condition. Since these representations develop in the social environment, the individuals' perceptions may also be related to the opinions of their caregivers. This systematic review aims at synthesising and critically appraising literature pertaining the relationship between illness perceptions and outcome in persons with multiple sclerosis and their caregivers. A literature search was conducted in MEDLINE, PsycINFO, and CINAHL. Only papers with the following characteristics were included: quantitative studies; written in English or Italian; published from 1992; investigating the relationship between illness perceptions and any outcome in persons with multiple sclerosis and/or their caregivers; using validated scales assessing illness perceptions. Twenty papers were included and appraised through the 16-item Quality Assessment Tool for Studies with Diverse Designs. The quality of the papers was acceptable. Eighteen out of 20 papers reported the existence of a moderate effect size when analysing the relationship between illness perceptions and outcome, whereby "positive" perceptions (e.g. stronger beliefs of control) related to better outcomes, while "negative" ones (e.g. attribution of negative consequences to the disease) related to worse outcome.

Mental Health Status of People with Multiple Sclerosis during the COVID-19 Pandemic

OBJECTIVE

This study assesses and compares the mental health status of people with multiple sclerosis (PwMS) in Poland during the second wave of the Coronavirus Disease 2019 (COVID-19) pandemic (November 2020) to a similar group whose mental health status was examined in November 2017. It also analyzed the psychological resources such as self-efficacy and health locus of control (HLC) and their relationship to mental health in both groups.

METHODS

Cross-sectional study included two groups of PwMS with 113 respondents each. The respondents completed the General Health Questionnaire-12 and questionnaires for assessing self-efficacy and HLC. The clinical and demographic data of participants were also collected.

RESULTS

No differences in mental health status were observed between the studied groups. A hierarchical regression model of the group studied in 2020 revealed that general self-efficacy (β = -0.21, p = 0.032), HLC-internal (β = -0.21, p = 0.035), and education (β = -0.18, p = 0.048) explained 18% of the variance in the mental health of PwMS, whereas according to the model of the group assessed in 2017 self-efficacy (β = -0.31, p < 0.001), HLC-chance (β = 0.45, p < 0.001), and HLC-internal (β = -0.37, p < 0.001) explained 48% of the variance.

CONCLUSIONS

Study results suggest that the pandemic and the related lockdown had no effect on the mental health status of PwMS. At the same time, it was noted that well known determinants of mental health such as self-efficacy and HLC seemed to retain their prominent role for mental functioning in the pandemic.

Translation and cultural validation of the Revised Illness Perception Questionnaire for Healthcare Professionals for Brazilian Portuguese

BACKGROUND

Multiple sclerosis progression and disability can be rated differently by healthcare professionals. Therefore, how physicians perceive the disease can impact treatment decisions. There are no previous studies on this matter.

OBJECTIVE

To translate and transculturally validate the Revised Illness Perception Questionnaire for Healthcare Professionals (IPQ-R HP), for use in Brazilian Portuguese.

METHODS

The process used to validate the IPQ-R HP was based on the steps presented in the guide proposed by Dorcas Beaton. The final version of the IPQ-R HP had 38 questions, divided into seven different dimensions to assess the patient's disease. Also, two clinical cases that were representative of real-life patients with multiple sclerosis (MS) were assembled to consider the two main profiles of the disease. We applied the questionnaire to neurologists at the Federal University of São Paulo (UNIFESP) to assess their perception of MS. These doctors also answered a brief survey to establish the profile of the interviewees. For statistical analysis, we used Bayesian CFA models and kappa statistics.

CONCLUSIONS

The kappa statistics showed a general agreement of 0.4. For the Bayesian CFAs with seven-factor correlation solution, we had a poor fit for case 1 with a 95% confidence interval ranging from -52.893 to 273.797 and a PPP of 0.107. Regarding case 2, the model did not converge even after 50,000 iterations, which indicated that the specified model (i.e. seven-factor correlation solution) for case 2 was inadmissible. Thus, the IPQ-R HP questionnaire in Brazilian Portuguese has not been validated.

Psychological well-being in people with multiple sclerosis and its association with illness perception and self-esteem

BACKGROUND

Illness perception and self-esteem were found to improve adjustment to disease in many chronic conditions. However, so far, little is known about the role of illness-appraisal and self-appraisal factors in psychological well-being in people with multiple sclerosis (MS). Thus, we aimed to assess the association between illness perception, self-esteem and psychological well-being in people with MS while controlling for sociodemographic variables, clinical variables, and sleep-related problems.

METHODS

The General Health Questionnaire-28, the Brief Illness Perception Questionnaire, the Rosenberg Scale of Self-esteem, the Expanded Disability Status Scale, the Pittsburgh Sleep Quality Index, and the Multidimensional Fatigue Inventory were used. Multiple linear regressions and mediation analyses were utilized to analyse the data.

RESULTS

Positive illness perception (p<0.001) and self-esteem (p<0.05) were significantly associated with psychological well-being in MS. Low income (p<0.05) and sleep-related problems (p<0.001) were significantly associated with lower level of psychological well-being in people with MS. Positive illness perception and self-esteem were able to diminish the association between low income (p>0.05), poor sleep quality (p<0.01), fatigue (p>0.05), and low level of psychological well-being. Self-esteem also mediated the association between illness perception and psychological well-being.

DISCUSSION

People with MS may benefit from psychological support aimed at promoting self-esteem and diminishing negative illness perception.

Effectiveness of film as a health communication tool to improve perceptions and attitudes in multiple sclerosis

BACKGROUND

Health communication tools like film are capable of reducing health disparities and could be effective in addressing negative illness perceptions of MS in Hispanics/Latinx.

OBJECTIVE

To test the feasibility of using a culturally appropriate short narrative film to examine illness perceptions overtime and attitudes in Hispanics/Latinx affected with MS.

METHODS

Participants were assigned to view a short narrative film (n = 130) or not (n = 106). The Brief Illness Perception Questionnaire (BIPQ) was used to examine illness perceptions at baseline, one and three months. Focus groups were conducted at 6 months. Measures of sociocultural integration were obtained. Individual group BIPQ domains were evaluated over time using paired sample t-test. Multivariate linear regression was used to examine predictors of BIPQ change.

RESULTS

A more positive perception of treatment (p < 0.0001) and understanding (p = 0.0003) were seen at 3 months for those exposed to film. Focus groups were effective in highlighting that the perceived disease prognosis, family support and awareness of MS contributes to attitudes. Exposure to film was found to be the strongest predictor (Beta:6.31, p = 0.01) of BIPQ change at three months.

CONCLUSION

Our results provide support that a short narrative film of MS in Hispanics/Latinx is a feasible intervention to change perceptions of MS to a more positive view.

High-Efficacy Disease-Modifying Therapies in People with Relapsing-Remitting Multiple Sclerosis: The Role of Risk Attitude in Treatment Decisions

BACKGROUND

Risk attitude is defined as the willingness to tolerate risk to achieve a greater expected return. Limited information is available on how relapsing-remitting multiple sclerosis people's perceptions about disease trajectory and risk attitude may influence treatment choices.

METHODS

A non-interventional study applying principles of behavioral economics was conducted to assess willingness to receive unwarranted high-efficacy disease-modifying therapy (DMT) according to best-practice guidelines. People with relapsing-remitting multiple sclerosis (PwRRMS) according to 2010 McDonald criteria completed a survey on symptom severity, risk preferences, and management of simulated case scenarios mimicking the current treatment landscape. PwRRMS's choice for high-efficacy agents was established as the participant's selection of monoclonal antibodies for case scenarios with at least 2 years of clinical and radiological stability.

RESULTS

A total of 211 PwRRMS were studied (mean age 39.1 ± 9.5 years, 70.1% female, mean Expanded Disability Status Scale score 1.8 ± 1.1). Almost 50% (n = 96) opted for a high-efficacy DMT despite the lack of evidence of disease activity. Younger age and risk-seeking behavior were associated with an increased likelihood of selecting unwarranted high-efficacy DMT [odds ratio (OR) 2.00, 95% confidence interval (CI) 1.02-3.93, p = 0.043, and OR 2.17, 95% CI 1.09-4.30, p = 0.027, respectively]. Clinical characteristics or subjective perception of symptom severity had no influence on participants' treatment choices.

CONCLUSION

Identifying PwRRMS with risk-seeking behavior would be crucial to implementing specific educational strategies to manage information on disease prognosis, treatment expectations, and safety risk knowledge.
