Objective:
Lower levels of social support in persons with Multiple Sclerosis (PwMS) are associated with myriad poor outcomes including worse mental health, lower quality of life, and reduced motor function (Kever et al., 2021). Social support has also been associated with physical pain (Alphonsus et al., 2021) and sleep disturbance (Harris et al., 2020) in PwMS. Pain is one of the most common symptoms of MS (Valentine et al., 2022) and is also known to be related to sleep disturbance (Neau et al., 2012). With these considerations in mind, the goal of the current study was to examine social support as a possible moderator in the relationship between pain and sleep quality in PwMS.
Participants and Methods:This cross-sectional study included 91 PwMS (females = 76). A neuropsychological battery and psychosocial questionnaires were administered. For sleep quality a composite was created from the sleep and rest scale of the Sickness Impact Profile (SIP), sleep-related items on the Multiple Sclerosis-Symptom Severity Scale (MS-SSS) (i.e., sleeping too much or sleep disturbance, fatigue or tiredness, and not sleeping enough), and an item from the Sleep Habits Questionnaire (SHQ) ("How many nights on average are you troubled by disturbed sleep?"). This composite (a = .76) has been used in prior research. Lower scores were indicative of worse sleep quality. Pain intensity and pain interference were measured using the Brief Pain Inventory (BPI). Pain intensity was calculated from four pain indices (i.e., pain at its worst in the last 24 hours, at its least in the last 24 hours, on average, and current pain at the time of the assessment) and pain interference was calculated from seven indices (i.e., general activity, mood, walking ability, normal work, relationships with others, sleep, and enjoyment of life). The Social Support Questionnaire (SSQ) measured average satisfaction with supports. A series of hierarchical linear regressions were conducted with the sleep quality index as the outcome variable and satisfaction with social supports, both indices of pain (intensity and interference), and their interactions as predictors. Then, simple effects tests were used to clarify the pattern of any significant interactions.
Results:Regression analysis revealed that the interaction between pain interference and satisfaction with social support was significant (p = .034). Simple effects tests revealed that when satisfaction with social support was high, pain interference was associated with better sleep quality (p < .001). The interaction between pain intensity and satisfaction with social supports was also significant (p = .014). Simple effects test revealed that at high levels of satisfaction with social supports, pain intensity was associated with better sleep quality (p < .001).
Conclusions:Satisfaction with social support moderated the relationship between pain interference and pain intensity on sleep quality in PwMS. Specifically, high satisfaction with social support buffers against the negative effects of pain interference and pain intensity on sleep quality in PwMS. This provides evidence that interventions aimed at increasing social supports in PwMS may lead improvements in sleep quality and reduce the impact of pain on sleep quality.

Objective:
Depression is highly prevalent in persons with multiple sclerosis (pwMS). A reformulated version of the learned helplessness theory posits that individuals who attribute the cause of negative events to personal factors (internal), perceive that the cause persists for a long period of time (stable), and believe it is present in all situations (global) are at an increased risk for depression. As such, it is critical to examine possible modifiable factors that buffer against the deleterious effects of negative attributional style. Therefore, the current study investigated whether stress moderates the relationship between negative attributional style and depression symptoms in an MS sample.
Participants and Methods:Thirty-six pwMS (30 Female, 6 Male) completed a comprehensive neuropsychological test battery and psychosocial questionnaires that assessed cognitive attributional style, daily stressors, and depression symptoms. The Attributional Style Questionnaire (ASQ) was used to create internal, stable, and global attribution dimension scores, as well as an overall attributional style score combining the three dimensions. Stress was quantified as the total score of perceived hassles from the Hassles and Uplifts Scale (HUS). Depression symptoms were measured using the Beck Depression Inventory-Fast Screen (BDI-FS). Hierarchical linear regressions were conducted with depression symptoms as the outcome variable. Each dimension of attributional style (internal, stable, global, or overall ASQ), stress, and their interactions were included as predictors. Simple effects tests were used to clarify the pattern of any significant interaction.
Results:Regression analyses revealed that the interaction between overall attributional style and stress was significant (p = .025). Simple effects tests revealed that overall attributional style was associated with depression symptoms only in pwMS with high levels of stress (p = .015). For the individual dimensions of the ASQ, several interactions were also significant. The interaction between the internal dimension and stress was significant (p= .009), such that internal attributions were associated with depression symptoms only in pwMS with high levels of stress (p = .002). The interaction between the stable dimension and stress was also significant (p = .01); stable attributional style was associated with depression symptoms only in pwMS with high levels of stress (p = .009). The interaction between the global dimension and stress was not significant.
Conclusions:Stress moderated the relationship between negative attributional style and depression symptoms in pwMS. Specifically, the internal and stable dimensions and overall attributional style were associated with increased depression symptoms only in pwMS who reported high levels of stress, but not in those with low levels of stress. Interventions aimed at reducing and managing stress may help protect against the effects of negative cognitive schemas on depression symptoms in MS. Additionally, previous research demonstrates that attributional style may be a malleable target of evidence-based psychotherapy (Seligman et al., 1988; Proudfoot et al., 2009). Our findings suggest that cognitive therapy specifically targeting the internal and stable dimensions of attributional style may be effective in modifying attributional style, perceptions of stress and, subsequently, improve depression outcomes in MS.

Objective:
Research examining co-occurring anxiety and depression in persons with multiple sclerosis (PwMS) is scarce, though an estimated 20% of PwMS experience clinically significant anxiety and depression (Gascoyne et al., 2019). Recent work by Hanna & Strober (2020) found that PwMS with comorbid anxiety and depression reported worse outcomes in all constructs of symptomatology, disease management, psychological well-being, and quality of life. However, it is unclear how co-occurring anxiety and depression symptoms may influence or exacerbate cognitive difficulties in PwMS. Further, considering there are high levels of comorbidity between depression, anxiety, and fatigue in PwMS, this study aims to examine the unique variances of depression, anxiety, co-occurring depression and anxiety, and fatigue on cognitive functioning.
Participants and Methods:86 PwMS (F=65,M=21) completed a comprehensive neuropsychological battery that included self-report measures of anxiety, depression, and fatigue. An intraindividual variability (IIV) composite score was calculated by combining standardized intraindividual standard deviation and maximum discrepancy scores on measures of attention/processing speed and memory for each participant. Lower scores indicate worse performance (i.e., greater variability). A hierarchical regression was conducted with IIV as the outcome variable and with depression, anxiety, cognitive fatigue, physical fatigue, and the interaction between depression and anxiety as predictors. Expanded Disability Status Scale (EDSS) scores were included as a covariate.
Results:The only model that included a statistically significant predictor of IIV was the final model, which included EDSS, depression, anxiety, cognitive fatigue, physical fatigue, and the interaction between depression and anxiety, F(6,77)=2.97, p=.01, AR2=.08. While the main effects of depression and anxiety were not significant, the interaction between depression and anxiety was significant, F(6,77)=7.20, p=.01, n2=.09. Simple effects tests revealed that the relationship between IIV and anxiety was marginally significant for those at the cutoff for clinical depression (square root BDI-FS=2; BDI-FS=4), F(6,77)=3.52, p=.07, n2=.04. However, the effect of anxiety on IIV increased as depression increased. For example, in those with high levels of depression (1.5 SD above the mean), there was a significant relationship between anxiety and IIV, F(6,77)=4.16, p=.04, n2=.05, though this was not the case for those with low levels of depression (1.5 SD below the mean), F(6,77)=0.01, p=.92, n2=.00.
Conclusions:The interaction between depression and anxiety predicted variability in performance such that those with high levels of depression and anxiety demonstrated significantly greater IIV. Since dispersion is considered a marker for neurocognitive integrity, this may suggest that co-occurring psychological disturbances are associated with poorer cognitive integrity, an important consideration for interventions and outcomes. While interventions aimed at treating co-occurring depression and anxiety have been largely overlooked within the MS literature (Butler et al., 2016), transdiagnostic interventions have been beneficial for general adult populations with co-occurring anxiety and depression (McEvoy et al., 2009). Future work should examine the efficacy of interventions aimed at addressing co-occurring depression and anxiety in PwMS, as this may help to improve cognitive functioning, as well as perception of functioning, which will likely further improve quality of life and overall well-being.

Objective:
Persons with multiple sclerosis (PwMS) are at increased risk for cognitive dysfunction. Considering the impact and potential ramifications of cognitive dysfunction, it is important that cognition is routinely assessed in PwMS. Thus, it is also important to identify a screener that is accurate and sensitive to MS-related cognitive difficulties, which can inform decisions for more resource-intensive neuropsychological testing. However, research focused on available self-report screeners has been mixed, such as with the Multiple Sclerosis Neuropsychological Screening Questionnaire (MSNQ). This study aims to clarify the relationship between subjective and objective assessment of cognitive functioning in MS by examining domain-specific performance and intraindividual variability (IIV).
Methods:87 PwMS (F = 65, M = 22) completed a comprehensive neuropsychological battery which included self- and informant-report measures of neurocognitive functioning. Scores were examined in relation to mean performance on five domains of cognitive functioning and two measures of IIV.
Results:The MSNQ-Self was inversely associated with executive function, verbal memory, and visual memory; it was not associated with IIV. The MSNQ-Informant was inversely associated with executive function and verbal memory, and positively associated with one measure of IIV. The MSNQ-Self showed a correlation of moderate effect size with depression (r = .39) while the MSNQ-Informant did not.
Conclusions:Results suggest that the MSNQ-Self and MSNQ-Informant show similar utility. Our findings also suggest that domains of executive function and memory may be most salient, thus more reflected in subjective reports of cognitive functioning. Future work should further examine the impact of mood disturbance with cognitive performance and IIV.

Objectives:
The current study explored how affective disturbances, particularly concomitant anxiety and depressive symptoms, impact baseline symptom self-reporting on the Post-Concussion Symptoms Scale (PCSS) in college athletes.
Methods:Athletes were separated into four groups (Healthy Control (HC) (n = 581), Depression Only (n = 136), Anxiety Only (n = 54), Concomitant Depression/Anxiety (n = 62)) based on their anxiety and depression scores. Groups were compared on Total PCSS Score as well as 5 PCSS Symptom Cluster scores (Cognitive, Physical, Affective, Sleep, and Headache).
Results:The three affective groups reported significantly greater symptomatology than HCs, with the Concomitant group showing the highest symptomatology scores across all clusters. The depressive symptoms only group also reported significantly elevated symptomatology, compared to HCs, on every symptom cluster except headache. The anxiety symptoms only group differed from HCs on only the cognitive symptoms cluster. Additionally, the Concomitant group reported significantly increased PCSS symptomatology, in terms of total scores and all 5 symptom clusters, compared to the depressive symptoms only and anxiety symptoms only groups.
Conclusions:Our findings suggest that athletes experiencing concomitant depressive/anxiety symptoms report significantly greater levels of symptomatology across all 5 PCSS symptom clusters compared to HCs. Further, results suggest that athletes experiencing concomitant affective disturbance tend to report greater symptomatology than those with only one affective disturbance. These findings are important because, despite the absence of concussion, the concomitant group demonstrated significantly elevated symptomatology at baseline. Thus, future comparisons with post-concussion data should account for this increased symptomatology, as test results may be skewed by affective disturbances at baseline.

Objectives:
The current study aims to examine the prevalence rates and the relationship of symptoms of depression, anxiety, and comorbid depression/anxiety with neurocognitive performance in college athletes at baseline. We hypothesized a priori that the mood disturbance groups would perform worse than healthy controls, with the comorbid group performing worst overall.
Methods:Eight hundred and thirty-one (M = 620, F = 211) collegiate athletes completed a comprehensive neuropsychological test battery at baseline which included self-report measures of anxiety and depression. Athletes were separated into four groups [Healthy Control (HC) (n = 578), Depressive Symptoms Only (n = 137), Anxiety Symptoms Only (n = 54), and Comorbid Depressive/Anxiety Symptoms (n = 62)] based on their anxiety and depression scores. Athletes’ neurocognitive functioning was analyzed via Z score composites of Attention/Processing Speed and Memory.
Results:One-way analysis of variance revealed that, compared to HC athletes, the comorbid group performed significantly worse on measures of Attention/Processing Speed but not Memory. However, those in the depressive symptoms only and anxiety symptoms only groups were not significantly different from one another or the HC group on neurocognitive outcomes. Chi-square analyses revealed that a significantly greater proportion of athletes in all three affective groups were neurocognitively impaired compared to the HC group.
Conclusions:These results demonstrate that collegiate athletes with comorbid depressive/anxiety symptoms should be identified, as their poorer cognitive performance at baseline could complicate post-concussion interpretation. Thus, assessing for mood disturbance at baseline is essential to obtain an accurate measurement of baseline functioning. Further, given the negative health outcomes associated with affective symptomatology, especially comorbidities, it is important to provide care as appropriate.

Objective:
People with Multiple Sclerosis (PwMS) and healthy controls (HCs) were evaluated on cognitive variability indices and we examined the relationship between fatigue and cognitive variability between these groups. Intraindividual variability (IIV) on a neuropsychological test battery was hypothesized to mediate the group differences expected in fatigue.
Method:Fifty-nine PwMS and 51 HCs completed a psychosocial interview and battery of neuropsychological tests and questionnaires during a 1-day visit. Fatigue in this study was measured with the Fatigue Impact Scale (FIS), a self-report multidimensional measure of fatigue. IIV was operationalized using two different measures, a maximum discrepancy score (MDS) and intraindividual standard deviation (ISD), in two cognitive domains, memory and attention/processing speed. Two mediation analyses with group (PwMS or HCs) as the independent variable, variability composite (memory or attention/processing speed) measures as the mediators, total residual fatigue (after accounting for age) as the outcome, and depression as a covariate were conducted. The Baron and Kenny approach to testing mediation and the PROCESS macro for testing the strength of the indirect effect were used.
Results:Results of a mediation analysis using 5000 bootstrap samples indicated that IIV in domains of both attention/processing speed and memory significantly mediated the effect of patient status on total residual fatigue.
Conclusion:IIV is an objective performance measure that is related to differences in fatigue impact between PwMS and HCs. PwMS experience more variability across tests of attention/processing speed and memory and this experience of variable performance may increase the impact of fatigue.

Objective:
Sleep deprivation is common among both college students and athletes and has been correlated with negative health outcomes, including worse cognition. As such, the current study sought to examine the relationship between sleep difficulties and self-reported symptoms and objective neuropsychological performance at baseline and post-concussion in collegiate athletes.
Method:Seven hundred seventy-two collegiate athletes completed a comprehensive neuropsychological test battery at baseline and/or post-concussion. Athletes were separated into two groups based on the amount of sleep the night prior to testing. The sleep duration cutoffs for these group were empirically determined by sample mean and standard deviation (M = 7.07, SD = 1.29).
Results:Compared with athletes getting sufficient sleep, those getting insufficient sleep the night prior to baseline reported significantly more overall symptoms and more symptoms from each of the five symptom clusters of the Post-Concussion Symptom Scale. However, there were no significant differences on objective performance indices. Secondly, there were no significant differences on any of the outcome measures, except for sleep symptoms and headache, between athletes getting insufficient sleep at baseline and those getting sufficient sleep post-concussion.
Conclusion:Overall, the effect of insufficient sleep at baseline can make an athlete appear similar to a concussed athlete with sufficient sleep. As such, athletes completing a baseline assessment following insufficient sleep could be underperforming cognitively and reporting elevated symptoms that would skew post-concussion comparisons. Therefore, there may need to be consideration of prior night’s sleep when determining whether a baseline can be used as a valid comparison.
