Quality of Life of People With Neuromuscular Diseases: The Role of Stigma

INTRODUCTION/AIMS

Stigma is thought to have a profound impact on quality of life (QoL) among people with neuromuscular diseases (NMD), but empirical evidence is limited. This study sought to explore associations of enacted stigma (social exclusion) and felt stigma (shame, fear of exclusion) with QoL.

METHODS

A cross-sectional survey was administered among NMD patients. The survey assessed (a) general QoL domains (physical/mental QoL); (b) specific QoL domains (emotional distress, satisfaction with participation); (c) enacted/felt stigma; (d) psychological factors (disease acceptance, self-compassion, self-criticism, self-esteem); (e) clinical factors (independence in activities of daily living, physical/mental comorbidities); and (f) socio-demographic factors (gender, age). Associations of enacted and felt stigma with all four QoL domains were analyzed using hierarchical multivariable linear regression analyses, adjusting for socio-demographic, clinical, and psychological factors.

RESULTS

Data of 261 patients (49% female, aged 18-96 years) were included in the analyses. Significant but weak associations of felt stigma with physical QoL (β = -0.36), mental QoL (β = -0.26), emotional distress (β = 0.27) and satisfaction with participation (β = -0.36) were observed. Enacted stigma was significantly weakly associated with three out of four QoL domains (β: -0.18 to -0.24), with the exception of emotional distress. Associations were virtually unchanged by adjustment for socio-demographic and clinical factors, yet attenuated after adjustment for psychological variables.

DISCUSSION

Our findings suggest that higher levels of stigma, most notably felt stigma, are associated with a lower QoL and emphasize the importance of addressing psychological factors in the monitoring and treatment of NMD patients.

Long-Term Outcomes From a Randomized Controlled Trial of Acceptance and Commitment Therapy (ACT) Compared to Standard Medical Care for Improving Quality of Life in Muscle Disorders

INTRODUCTION/AIMS

A previous randomized controlled trial showed that guided self-help acceptance and commitment therapy plus standard medical care (ACT+SMC) was superior to standard medical care alone (SMC) for improving quality of life (QoL) and mood at 9-weeks post randomization in a sample of people with muscle disorders (MD). This follow-up study evaluated whether these effects were maintained in the longer term alongside individual patterns of response.

METHODS

The original study was a two-arm parallel group randomized controlled trial, which compared ACT+SMC to SMC. The primary outcome of QoL was assessed with the Individualized Neuromuscular Quality of Life Questionnaire. We recruited people with different MDs from UK National Health Service clinics and patient registries. In this follow-up study, we re-administered all outcome measures to participants at 6 months post randomization.

RESULTS

Questionnaires were completed by 109 participants (70.3% of the original sample). At six months, the adjusted group difference in QoL continued to favor ACT+SMC, which was significant with moderate effect size. Improvements in secondary outcomes of mood and aspects of psychological flexibility also favored ACT+SMC. Reliable improvement was evident in 33.9% of the ACT+SMC group and 5.7% of the SMC group. Reliable deterioration was uncommon following ACT+SMC (1.8% of participants.) DISCUSSION: The beneficial impacts of guided self-help ACT for QoL and mood were maintained in the longer-term. A third of participants showed response to this brief intervention, and negative individual outcomes were very rare. As is common in psychological interventions, there was a considerable group of non-responders.

Acceptability and potential benefit of a self-compassion intervention for people living with amyotrophic lateral sclerosis: a mixed methods pilot study

OBJECTIVE

This proof-of-concept study aimed to explore the acceptability and potential benefit of a self-guided online self-compassion intervention to aid resilient coping and reduce emotional distress among patients and caregivers living with ALS.

METHODS

A single-arm pilot study was conducted in 20 adults living with ALS either as a patient or as a caregiver. Acceptability was examined using questionnaires (n = 20) and semi-structured interviews (n = 9). Potential benefit was assessed as changes in self-compassion, self-criticism and emotional distress, determined using psychological questionnaires at 3 and 6 weeks. Questionnaires were analyzed using linear mixed-effects models and interview data using inductive thematic analysis.

RESULTS

Out of 20 participants who started the intervention, 16 completed the study (80%). The majority of study completers (12/16) were satisfied with the intervention, but the data suggest room for improvement in terms of personalization. Qualitative data revealed multiple psychological benefits of using the intervention, including self-kindness, emotional self-awareness and savoring. Although not statistically significant, quantitative data showed positive trends with increased self-compassion (mean difference: 2.07; 95% CI: -.5.76 - 1.63) and reduced self-criticism (mean difference: -2.62; 95% CI: -.1.97 - 7.23) and emotional distress (mean difference: -2.49; 95% CI: -.51 - 5.50) at week 6 compared to baseline.

CONCLUSIONS

The findings suggest that a self-compassion intervention is acceptable to people living with ALS, but its beneficial effects and the mechanisms involved have yet to be established in larger and more diverse samples, using controlled designs.

Common Characteristics Between Frailty and Myotonic Dystrophy Type 1: A Narrative Review

Myotonic dystrophy type 1 (DM1) is an inherited neuromuscular disorder often considered a model of accelerated aging due to the early appearance of certain age-related clinical manifestations and cellular and molecular aging markers. Frailty, a state of vulnerability related to aging, has been recently studied in neurological conditions but has received considerably less attention in neuromuscular disorders. This narrative review aims to describe 1) the common characteristics between Fried's frailty phenotype criteria (muscular weakness, slow gait speed, weight loss, exhaustion/fatigue, and low physical activity) and DM1, and 2) the psychological and social factors potentially contributing to frailty in DM1. This review gathered evidence suggesting that DM1 patients meet four of the five frailty phenotype criteria. Additionally, longitudinal studies report the deterioration of these criteria over time in DM1. Patients also exhibit psychological/cognitive and social factors that might contribute to frailty. Monitoring frailty criteria in the DM1 population could help to implement timely preventions and interventions to reduce the disease burden and severity of frailty symptoms.

Effects of a neuropsychosocial teleassistance intervention on social cognition and health-related quality of life of pediatric patients with neuromuscular diseases

OBJECTIVE

This study aimed to determine the effects of a neuropsychosocial teleassistance group-based intervention on improving social cognitive functioning and health-related quality of life (HRQoL) in pediatric neuromuscular diseases (NMD).

METHODS

Thirty-five pediatric patients with NMD were assigned to the neuropsychosocial intervention program (n = 20) or waiting list control condition (n = 15). The intervention group received an integrative approach that combines training in social cognition with cognitive behavioral therapy. All participants completed a neuropsychological and clinical assessment at baseline and follow-up, which included tests of social cognition, both for emotion recognition and theory of mind, and HRQoL. Repeated-measures multivariate analysis of covariance was used to determine the effects of the teleassistance program.

RESULTS

Group × Time interactions revealed significant improvements in the intervention group as compared with the control group for different social cognition's indicators (AR NEPSY-II: p = .003, η2p = .24; TM NEPSY: p < .001, η2p = .35; Verbal task: p < .001, η2p = .35; Happé's Strange Stories: p = .049, η2p = .11) and HRQoL (Psychosocial health: p = .012, η2p = .18; Emotional functioning: p = .037, η2p = 0.13; Social functioning: p = .006, η2p = .21; Total: p = .013, η2p = .17), showing medium to large effects.

CONCLUSIONS

Patients receiving the neuropsychosocial intervention showed improvements in their social cognition performance and psychosocial HRQoL, providing evidence about the positive effects of the program in pediatric patients with NMD. This should be considered in further research and interventions in this field.

Psychosocial resources and psychopathology among persons with neuromuscular disorders during the COVID-19 pandemic

BACKGROUND

The COVID-19 pandemic substantially affected the lives of persons with inherited neuromuscular disorders (INMD), causing disruption in clinical and support services. While several studies have investigated mental health, distress and psychosocial resources in the general population during the pandemic, little is known about the experience of persons with INMD.

METHODS

This study was aimed to fill this gap by jointly investigating both psychopathological symptoms and psychosocial resources - specifically, resilience and perceived social support - among persons with INMD during the pandemic, taking into account demographic and clinical factors. Between April and December 2020, 59 participants with INMD (aged 15-59, 71.2% M) completed a questionnaire collecting demographic and clinical data, the Multidimensional Scale of Perceived Social Support, the Resilience Scale for Adults, and the Achenbach System of Empirically Based Assessment.

RESULTS

Overall, participants showed good levels of resilience and perceived social support. A minority of participants reported clinically relevant psychopathological symptoms, 28.81% for anxiety and depression. Most psychopathological symptoms were negatively correlated with resilience (-0.347 < r < - .420), but not significantly associated with social support. Consistent with previous studies, regression analyses highlighted that participants with Duchenne muscular dystrophy were more prone to report anxious and depressive symptoms (B = 1.748, p = .028, OR = 5.744), and participants with myotonic dystrophy, attention problems (B = 2.339, p = .006, OR = 10.376). Resilience emerged as a potential predictor of lower anxious-depressive symptoms (B=-1.264, p = .012, OR = 0.283).

CONCLUSIONS

The findings suggest the importance to investigate psychosocial resources in addition to psychopathology among persons with INMD, and to design interventions supporting resilience as a protective factor for mental health promotion.

Difficulties in social cognitive functioning among pediatric patients with muscular dystrophies

Introduction

Pediatric muscular dystrophies (MDs) are a heterogeneous group of rare neuromuscular diseases characterized by progressive muscle degeneration. A neuropsychosocial approach is crucial for these patients due to associated cognitive, behavioral, and psychiatric comorbidities; however, the social cognitive domain has not been adequately addressed.

Methods

This study aimed to analyze on social cognition performance in a pediatric MD patient cohort. This cross-sectional study included 32 pediatric patients with MD and 32 matched-healthy controls. The Social Perception Domain of the NEPSY-II, the Reading the Mind in the Eyes Test-Child and Happé's Strange Stories Test were administered. General intelligence and behavioral and emotional symptoms were controlled for to eliminate covariables' possible influence. The assessments were performed remotely.

Results

Children with MDs performed significantly worse on most of the social cognition tasks. The differences found between the groups could be explained by the level of general intelligence for some aspects more related to theory of mind (ToM) (TM NEPSY-II: F = 1.703, p = .197; Verbal task: F = 2.411, p = .125; RMET-C: F = 2.899, p = .094), but not for emotion recognition. Furthermore, these differences were also independent of behavioral and emotional symptoms.

Discussion

In conclusion, social cognition is apparently impaired in pediatric patients with MD, both for emotion recognition and ToM. Screening assessment in social cognition should be considered to promote early interventions aimed at improving these patient's quality of life.
