Relationship between physical activity and coping with stress in people with multiple sclerosis: A moderated mediation model with self-efficacy and disability level as variables / Relación entre actividad física y afrontamiento del estrés en personas con esclerosis múltiple: un modelo de mediación moderada con autoeficacia y nivel de discapacidad como variables

Purpose: An increasing number of studies support the beneficial relationship between physical activity and stress coping in people with multiple sclerosis (MS). However, there has been limited understanding of the variables that may influence the nature of this relationship. Therefore, based on the social-cognitive framework and previous research, we aimed to examine the association between the habitual physical activity of people with MS and their coping effectiveness. Furthermore, we sought to determine the extent to which self-efficacy acts as a mediator in this relationship, considering the level of disability as a moderator variable. Methods: In this cross-sectional study, a total of 351 people with MS participated. The participants were asked to complete several assessment tools, including the Mini-COPE Inventory for Measurement—Coping with Stress, the Generalized Self-Efficacy Scale, and the Godin Leisure-Time Exercise Questionnaire. Additionally, a neurologist assessed the severity of the disease using the Expanded Disability Status Scale. Information on the demographic and clinical characteristics of the participants was collected via a self-report survey. Two moderated mediation analyses were conducted as part of the study. Results: The study findings indicated a positive correlation between engagement in physical activity and self-efficacy among participants with high and medium disability levels. This, in turn, demonstrated a positive association with effective stress-coping strategies and a negative association with ineffective coping methods. In particular, a significant relationship was observed between involvement in physical activity and self-efficacy in participants with high disability, while it was not statistically significant in participants with low disability.(AU)

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 (ß = -0.21, p = 0.032), HLC-internal (ß = -0.21, p = 0.035), and education (ß = -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 (ß = -0.31, p < 0.001), HLC-chance (ß = 0.45, p < 0.001), and HLC-internal (ß = -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.

The Effects of Nordic Walking With Poles With an Integrated Resistance Shock Absorber on Cognitive Abilities and Cardiopulmonary Efficiency in Postmenopausal Women.

Late adulthood is associated with atrophy of brain areas, which contribute to cognitive deterioration and increase the risk of depression. On the other hand, aerobic exercise can improve learning and memory function, ameliorate mood, and prevent neurodegenerative changes. This study demonstrates the effect of Nordic walking (NW) and NW with poles with an integrated resistance shock absorber (NW with RSA) on aerobic capacity and body composition in postmenopausal women. It also measures the brain-derived neurotrophic factor (BDNF) and glial cell line-derived neurotrophic factor (GDNF) serum levels and determines correlations with cognitive functions and depression symptoms. These relationships with the use of NW with RSA as a new form of exercise have not been described thus far. In this study, 31 women (NW - 16, NW with RSA - 15) participated in eight weeks of training. The findings showed that only NW with RSA training caused a significant decrease in body mass and body mass index (p < 0.05). There were no significant changes in GDNF levels between groups studied. Regarding BDNF, a significant decrease (p < 0.05) in the NW group and an increase (not statistically significant) in the NW with RSA group was found. A comparative analysis of cognitive and depression outcomes and changes in BDNF and GDNF concentration showed no significant differences in the efficacy of either form of training. Training loads resulted in a significant increase in VO2max in both the NW (p < 0.01) and NW with RSA (p < 0.05) groups. This indicates an improvement in cardiopulmonary efficiency of the examined women.

Relationship between Pre-Competition Mental State and Sport Result of Disabled Boccia Athletes.

The relationship between sport result and pre-competition mental state of 109 boccia athletes was analyzed. Mental state was described by: athletic identity, self-esteem, self-efficacy for sports, hope for success, fear of failure, anxiety, and expectancy of success. Correlation analyses were made for all four boccia classes (BC1, BC2, BC3, and BC4) and revealed that only athletic identity was associated with sport result in class BC4. Four hierarchical multiple regression models (for BC1, BC2, BC3, and BC4 boccia classes) were created, with sport result as the dependent variable. Only the BC4 model was significant and included athletic identity, anxiety, self-efficacy for sports, and expectancy of success, which explained 49% of variance in sport result. BC4 class results indicate that psychological variables have a potential impact on sport performance in boccia, and the type and level of disability should be taken into account.

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

CONTEXT: Patients with multiple sclerosis (MS) experience many negative, seriously aggravating disease symptoms, and hence, research studies are utmost required to improve their coping with symptoms. Our research is an attempt to show ways to increase participation of patients with MS in the treatment and treatment planning process, as well as in managing the symptoms of the disease. OBJECTIVES: To examine the relationship between perception of MS impact and treatment efficacy beliefs in patients with MS and the extent to which self and illness appraisals can be regarded as mediator variables in this relationship. METHODS: The cross-sectional study included 278 MS patients who completed the Treatment Beliefs Scale, Multiple Sclerosis Impact Scale, Generalized Self-Efficacy Scale, Rosenberg Self-Esteem Scale, and Brief Illness Perception Questionnaire. Demographic and clinical characteristics of the participants were collected with a self-report survey. RESULTS: Illness perception and general self-efficacy mediated the relationship between perception of MS impact and treatment efficacy beliefs under the control of age and time from diagnosis. The standardized indirect effects for illness perception and general self-efficacy were -0.131 95% CI [-0.2029, -0.0739] and -0.086 95% CI [-0.1663, -0.0165], respectively. CONCLUSION: Our results indicate that worse perception of physical condition in patients with MS is associated with more negative treatment efficacy beliefs, and that this association is mediated by self-efficacy and illness perception. To inhibit the increase of negative treatment efficacy beliefs, health care specialists can work on improving self-efficacy and illness appraisals.

Sports Injuries in Wheelchair Rugby - A Pilot Study.

The aim of the study was to analyze etiology and the incidence of sports injuries among wheelchair rugby players. Moreover, we verified if the levels of aggressiveness and anger presented by the athletes and their roles in the team influenced the incidence and severity of the injuries. The study involved 14 male players, members of the Polish National Wheelchair Rugby Team. During a 9-month period, the athletes participated in up to 9 training camps and 4 Wheelchair Rugby tournaments. The study was based on the Competitive Aggressiveness and Anger Scale, registry of sports injuries consulted and non-consulted with a physician and a demographic questionnaire. The following observations were made during the 9-month period corresponding to a mean of 25 training and tournament days: 1) wheelchair rugby players experienced primarily minor injuries (n=102) that did not require a medical intervention, 2) only four injuries needed to be consulted by a physician, 3) sports injuries occurred more frequently among offensive players than in defensive players, 4) offensive players showed a tendency to higher levels of anger and aggressiveness than defensive players. It can be concluded that wheelchair rugby is a discipline associated with a high incidence of minor injuries that do not require a medical intervention. The incidence rate of injuries during the analyzed period was 0.3 per athlete per training day.
