Relation between anxiety, depression and locus of control of patients with multiple sclerosis

The Association of Health Locus of Control with Clinical and Psychosocial Aspects of Living with Multiple Sclerosis

Health Locus of control (LOC) refers to one's beliefs regarding control over one's health. This study aimed to determine the relationship between LOC on clinical and psychosocial aspects associated with multiple sclerosis (MS). 5059 participants with MS completed a questionnaire pack including the Multidimensional Health Locus of Control Scale. Associations between LOC and sociodemographic (age, gender, educational level) and clinical variables (duration, disability, depression, anxiety, self-efficacy, QoL) were explored. LOC was found to be significantly associated with all of the clinical variables and age, but not gender or educational level. When controlling for level of disability, Chance (CLOC) was associated with higher self-efficacy, lower anxiety and higher QoL than Powerful Others (PLOC), while Internal (ILOC) had no association. The proportion with ILOC preference was lower in increased disability. In MS, believing that health is controlled mainly by chance confers the most benefit with regard to quality of life. There is prima-facie evidence that LOC preference changes with MS progression, in a pattern that is protective against psychological distress.

Flare-Ups in Crohn's Disease: Influence of Stress and the External Locus of Control

(1) Background: The aim of this study was to explore the role of perceived stress and the health locus of control in Crohn's disease and their influence upon the development of flare-ups of this disease. (2) Methods: Stress and the external locus of control were evaluated in a sample of 64 Crohn's patients (flare-up phase versus latency phase). The perceived stress scale (PSS-14) and the multidimensional health locus of control scale were the measurement instruments used. (3) Results: The results indicate that the patients have high stress levels during a flare-up (26.13; 27.44; 28.79; 29.67); high stress levels (28.07; 29.67; 27.44; 28.07) if they have a high external locus of control; and that the external locus of control and stress levels have a significant influence upon the existence of flare-ups in those patients with low external locus of control levels (χ2 = 11.127; df = 1: p < 0.001). (4) Conclusions: Actions aimed at reducing stress and external locus of control levels are necessary in Crohn's disease.

Multiple sclerosis: relationship between locus of control and quality of life in persons with low versus high disability

Background: Health Locus of Control (HLOC) is the degree to which individuals believe that their health outcomes are controlled by ‘external’ factors – environmental forces, chance, fate, other people, or some higher power – or by ‘internal’ factors – their own behavior or action. Most of the literature on HLOC associates an Internal Health Locus of Control (IHLOC) to pro-health behaviors and better health outcomes. However, a few studies also suggest that in chronic illnesses, an External Health Locus of Control (EHLOC) could be beneficial with respect to pro-health behaviors and perceptions of Quality of Life (QoL), challenging assumptions about what leads to the most effective psychological coping in the face of difficult circumstances. Multiple sclerosis (MS) is a chronic immune condition of the central nervous system and the most frequent cause of non-traumatic disability in young adults, often despite treatment. Method: The primary goal of this non-experimental, cross-sectional, quantitative study of 89 individuals with MS was to explore the HLOC of individuals with MS, and to identify whether holding an EHLOC positively impacts the MS patients’ perceived QoL while taking into consideration their level of disability. Results: This research found that individuals with higher disability scores tended to hold more EHLOC beliefs, and that there was a significant correlation between QoL and holding EHLOC beliefs. Conclusion: This study was able to capture the importance of control beliefs in the QoL of individuals with MS with higher disability. The clinical implications of the findingare explored and areas for further research are suggested.

Moving beyond emotions in Parkinson's disease

OBJECTIVE

Emotion recognition is a fundamental neurocognitive capacity that is a critical predictor of interpersonal function and, in turn, mental health. Although people with Parkinson's disease (PD) often exhibit difficulties recognizing emotions, almost all studies to date have focused on basic emotions (happiness, sadness, anger, surprise, fear, and disgust), with little consideration of how more cognitively complex self-conscious emotions such as contempt, embarrassment, and pride might also be affected. Further, the few studies that have considered self-conscious emotions have relied on high intensity, static stimuli. The aim of the present study was to therefore provide the first examination of how self-conscious emotion recognition is affected by PD using a dynamic, dual-intensity measure that more closely captures how emotion recognition judgements are made in daily life.

METHOD

People with PD (n = 42) and neurotypical controls (n = 42) completed a validated measure of self-conscious facial emotion recognition. For comparative purposes, in addition to a broader clinical test battery, both groups also completed a traditional static emotion recognition measure and a measure of self-conscious emotional experience.

RESULTS

Relative to controls, the PD group did not differ in their capacity to recognize basic emotions but were impaired in their recognition of self-conscious emotions. These difficulties were associated with elevated negative affect and poorer subjective well-being.

CONCLUSIONS

Difficulties recognizing self-conscious emotions may be more problematic for people with PD than difficulties recognizing basic ones, with implications for interventions focused on helping people with this disorder develop and maintain strong social networks.

PRACTITIONER POINTS

This is the first direct investigation into how the recognition of self-conscious emotion is affected in Parkinson's disease using dynamic, dual-intensity stimuli, thus providing an important extension to prior literature that has focused solely on basic emotion recognition and/or relied on static, high-intensity stimuli. Results revealed preserved basic facial emotional recognition coexisting with impairment in all three self-conscious emotions assessed, therefore suggesting that the latter stimuli type may function as a more sensitive indicator of Parkinson's disease-related social cognitive impairment. Problems with self-conscious emotion recognition in people with Parkinson's disease were associated with poorer broader subjective well-being and increased negative affect. This aligns with the broader literature linking interpersonal difficulties with poorer clinical outcomes in this cohort.

Coping profiles in multiple sclerosis: Comparison of personal resources

BACKGROUND

Identifying the profiles of multiple sclerosis (MS) patients who employ similar patterns of coping may improve the understanding of how coping is associated with psychological adjustment. The purpose of this study was to identify the groups of MS patients using different coping strategies and compare the levels of psychological resources across the groups.

METHODS

In this cross-sectional study 382 patients with MS completed a battery of self-report measures that assessed their use of different coping strategies, optimism, self-efficacy, health locus of control (HLC), and perception of disease. The groups with different coping profiles were selected by performing a cluster analysis.

RESULTS

Five different coping profiles were highlighted and were defined as follows: "Emotional," "Temperate," "Active," "Passive," and "Problem copers." Significant differences were detected between the groups in the levels of optimism, self-efficacy, HLC, and perception of disease.

CONCLUSION

Patients with MS use a varied repertoire of coping strategies, which allowed distinguishing coping profiles. Groups representing particular profiles differ in terms of psychological resources. This study contributed to increasing the interest in investigating coping profiles. Identifying subgroups of individuals based on their coping profiles and recognizing the differences is important for providing psychological support.

Psychological factors associated with self-management in multiple sclerosis

OBJECTIVE

Patient's engagement in their own treatment has been shown to improve clinical outcomes. A better understanding of the association between self-management in multiple sclerosis (MS) and potentially modifiable psychological factors may provide clinicians with strategies to design and stimulate better patient activation for self-managing health. Therefore, in this study, we examined whether cognitive factors, namely self-efficacy, acceptance of illness, optimism, and health locus of control (HLC), are associated with self-management in MS.

METHODS

This is a cross-sectional study. A total of 382 patients with MS who completed the MS Self-Management Scale-Revised and the questionnaires that measure self-efficacy, optimism, illness acceptance, and HLC were included in the study.

RESULTS

A hierarchical multiple regression revealed that power of others' HLC (b = 0.42, P ≤ .001), optimism (b = 0.27, P ≤ .01), internal HLC (b = -0.11, P = .017), and self-efficacy (b = 0.11, P = .031), together with control variables (longer disease duration and higher disability), explained 30% of the variance in the dependent variable.

CONCLUSIONS

In the case of MS, self-management is associated with patient's perception that healthcare professionals control their health, higher self-efficacy, optimism, and, surprisingly, lower internal HLC. The results of this study indicate the vital role of the healthcare staff in encouraging the patients with MS toward activities related to self-management and provide new insights on the psychological intervention aimed at improving self-management by patients.

Health locus of control and mental health in patients with multiple sclerosis: Mediating effect of coping strategies

In patients with multiple sclerosis (MS), mental health is significantly affected and conditioned by many factors, including psychological ones. This study team aimed to determine whether different coping strategies mediate the relationship between health locus of control (HLC) and mental health in MS patients. In this cross-sectional study, a total of 382 patients with MS were included. The patients completed General Health Questionnaire-12, Coping Inventory for Stressful Situations, and Multidimensional Health Locus of Control Scale. The demographic and clinical characteristics of the patients were collected using a self-report survey and neurological assessment. A mediation analysis was used to test the study hypothesis. Problem-oriented coping was found to be a significant mediator in the relationship between internal HLC and mental health (indirect effect: -0.129 [95% confidence interval [CI]: -0.193, -0.079]; standardized indirect effect: -0.113 [95% CI: -0.165, -0.070]). Emotion-focused coping was found to be a significant mediator in the relationship between power of others HLC and mental health (indirect effect: 0.114 [95% CI: 0.058, 0.178]; standardized indirect effect: 0.125 [95% CI: 0.062, 0.195]). Emotion-focused coping was also found to be a significant mediator in the relationship between chance HLC and mental health (indirect effect: 0.215 [95% CI: 0.154, 0.281]; standardized indirect effect: 0.209 [95% CI: 0.149, 0.272]). Patients with internal HLC were found to have positive mental health due to their problem-focused coping strategies, while patients with external HLC had worse mental health as they used more emotion-focused strategies. Hence, problem-focused and emotion-focused coping strategies can be considered mediators of the relationship between HLC and mental health in patients with MS.

Language as a Threat: Multimodal Evaluation and Interventions for Overwhelming Linguistic Anxiety in Severe Aphasia

Linguistic anxiety (LA) is an abnormal stress response induced by situations that require the use of verbal behavior, and it is accentuated during language testing in persons with aphasia (PWA). The presence of LA in PWA may jeopardize the interpretation of cognitive evaluations, leading to biased conclusions about the severity of the language alteration and the effectiveness of the treatments. In the present study, we report the case of a woman (Mrs. A) with severe chronic mixed transcortical aphasia due to left frontal and parietal hemorrhages that partially spared the perisylvian area. Mrs. A was treated with the dopamine agonist Rotigotine alone and combined with Intensive Language-Action Therapy (ILAT). Complementary evaluations included autonomic reactivity during the performance of different language tasks, resting state functional magnetic resonance imaging (rs-fMRI) and [18F]-fluorodeoxyglucose positron emission tomography (18F-FDG-PET). We found that formal language testing in a clinical setting triggered a dramatic increase of automatic echolalia, perseverations and frustration, making the task completion difficult. The treatment improved aphasia, but gains were more robust when evaluation was performed by Mrs. A's husband at home than by clinicians. Autonomic evaluation under Rotigotine revealed higher reactivity during tasks tapping an impaired function in comparison with a task evaluating a preserved function (verbal repetition). Baseline 18F-FDG-PET analysis showed decreased metabolic activity in left limbic-paralimbic areas, whereas rs-fMRI revealed compensatory activity in the right hemisphere. We also analyzed the different factors (e.g., premorbid personality traits, task difficulty) that may have contributed to LA in Mrs. A during language testing. Our findings emphasize the usefulness of implicating adequately trained laypersons in the evaluation and treatment of PWA showing LA. Further studies using multidimensional evaluations are needed to disentangle the interplay between anxiety and abnormal language as well as the neural mechanisms underpinning LA in PWA.

Examining Depressive Symptoms and Their Predictors in Malaysia: Stress, Locus of Control, and Occupation

The 2015 National Health and Morbidity Survey estimated that over 29% of the adult population of Malaysia suffers from mental distress, a nearly 3-fold increase from the 10.7% estimated by the NHMS in 1996 pointing to the potential beginnings of a public health crisis. This study aimed to better understand this trend by assessing depressive symptoms and their correlates in a cross-section of Malaysians. Specifically, it assesses stress, perceived locus of control, and various socio-demographic variables as possible predictors of depressive symptoms in the Malaysian context. A total of 728 adults from three Malaysian states (Selangor, Penang, Terengganu) completed Beck’s depression inventory as well as several other measures: 10% of respondents reported experiencing severe levels of depressive symptoms, 11% reported moderate and 15% reported mild depressive symptoms indicating that Malaysians are experiencing high levels of emotional distress. When controlling for the influence of other variables, depressive symptoms were predictably related to higher levels of stress and lower levels of internal locus of control. Ethnic Chinese Malaysians, housewives and those engaged in professional-type occupations reported less depressive symptoms. Business owners reported more depressive symptoms. Further research should look more into Malaysians’ subjective experience of stress and depression as well as explore environmental factors that may be contributing to mental health issues. It is argued that future policies can be designed to better balance individual mental health needs with economic growth.

Factors Associated with Poststroke Anxiety: A Systematic Review and Meta-Analysis

Background and Purpose. Anxiety affects 25% of stroke survivors. There are no effective treatments. Poststroke depression, prestroke anxiety and depression, locus of control, coping, confidence, fatigue, and sleep are factors that may be associated with poststroke anxiety and can potentially be targeted by therapy. We systematically reviewed the literature and performed a meta-analysis to identify associations with these factors. Methods. We searched electronic databases from January 2014 to July 2015 to complement a literature search performed from inception to May 2014. Study quality was assessed using an internationally endorsed checklist. We used odds ratios (ORs) to estimate the strength of associations and random-effects modelling to calculate summary effect sizes. Results. There were 24 studies recruiting 15448 patients. Quality of reporting was satisfactory. 13 studies with 2408 patients reported associations between poststroke anxiety and poststroke depression (OR = 4.66, 95% confidence interval: 2.23, 9.74). One study reported association with prestroke anxiety, three with prestroke depression, one with fatigue, and two with sleep. No studies reported on locus of control, coping, or confidence. Conclusion. Poststroke anxiety was associated with depression but there are limited data on other modifiable associations. Further research is needed to identify potential targets for treatment.

Lifestyle, medication and socio-demographic determinants of mental and physical health-related quality of life in people with multiple sclerosis

Background

Health-related quality of life (QOL) is a key outcome for people with multiple sclerosis (MS). While modifiable lifestyle factors, like smoking, physical activity and vitamin D, have strong associations with development and progression of MS, few studies have examined such associations with QOL.

Methods

Using patient-reported data from 2312 people with MS from 54 countries, regression models explored associations of socio-demographic, therapeutic and lifestyle factors with QOL, using the Multiple Sclerosis Quality of Life-54 (MSQOL-54).

Results

Participants were on average 45.6 years old, 82.4% women, mostly partnered (74.1%), with a university degree (59.5%). Controlling for socio-demographic factors and disability, factors associated with better physical health composite (PHC) (on a 100 point scale) were: moderate and high physical activity compared to low (5.9 [95% confidence interval: 4.2, 7.6] and 9.9 [CI: 8.1, 11.6] points higher score respectively); non-smoking compared to current smoking (4.6 points [CI: 2.4, 6.7]); better diet (per 10 points on the 100 point Diet Habits Questionnaire scale (DHQ) 1.6 points [CI: 1.0, 2.2] points); normal body mass index (BMI) versus overweight or obese (2.1 points [CI: 0.4, 3.7] and 2.4 points [CI: 0.5, 4.3]); fewer comorbidities (4.4 points [CI: 3.9, 4.9]); and not taking a disease-modifying drug (DMD) (2.1 points [CI: 0.7, 3.4]).

Better mental health composite (MHC) determinants were: moderate and high physical activity compared to low (4.0 points [CI: 2.0, 6.0] and 5.7 points [CI: 3.5, 8.0]); non-smoking compared to current (6.7 points [CI: 4.1, 9.3]); better diet (2.8 points [CI: 1.9, 3.5]); normal BMI versus overweight or obese (3.1 points [CI: 1.1, 5.1] and 3.5 points [CI: 1.3, 5.7]); meditating regularly (2.2 points [CI: 0.2, 4.2]); and no DMD use (2.9 points [CI: 1.3, 4.6]).

Conclusions

While causality cannot be concluded from cross-sectional data, the associations between modifiable lifestyle factors and QOL suggest significant potential for secondary prevention of the known deterioration of QOL for people with MS through lifestyle risk factor modification.

‘Locus of control’, health-related quality of life, emotional distress and disability in Parkinson’s disease

This cross-sectional study evaluated locus of control and its subscales in Parkinson’s disease. A total of 50 consecutive Parkinson’s disease participants and 50 healthy volunteers (control group) were enrolled. External locus of control was significantly higher in Parkinson’s disease participants, whereas internal locus of control had no significant differences. External locus of control and internal locus of control were correlated in control group, but not in Parkinson’s disease. In Parkinson’s disease participants, external locus of control was negatively associated with health-related quality of life as well as positively associated with emotional distress and disease severity (but not with disability). After adjusting to confound variables, the associations remained. On the other hand, internal locus of control was negatively associated with depression.

The influence of sense of control and cognitive functioning in older cancer patients' depression

OBJECTIVE

This study aimed to evaluate the associations between depression, sense of control, and cognitive functioning, as well as the predictive power of sense of control and cognitive functioning in older cancer patients' depression.

METHODS

Eighty-six cancer patients were referred to a palliative care unit. They completed the 15-item Geriatric Depression Scale, the Cancer Locus of Control, and the Mini Mental State Examination questionnaires.

RESULTS

Higher perceived control over the 'course of illness' was associated with higher levels of depressive symptoms (p < 0.0005), whereas lower perceived control over the 'cause of illness' was associated with higher depressive symptoms. The same results were found for 'cause of illness' between non-depressed and depressed patients (p = 0.001). Multivariate analysis revealed that whereas an external orientation in 'course of illness' increased the likelihood of depression (p = 0.002), an external orientation in 'cause of illness' decreased the likelihood of depression (p = 0.05).

CONCLUSIONS

Older cancer patients' sense of control orientation over the course of illness and the cause of illness predicted the levels of depressive symptomatology.

Exploring positive pathways to care for members of the UK Armed Forces receiving treatment for PTSD: a qualitative study

OBJECTIVE

To examine the factors which facilitate UK military personnel with post-traumatic stress disorder (PTSD) to engage in help-seeking behaviours.

METHODS

The study recruited active service personnel who were attending mental health services, employed a qualitative design, used semi-structured interview schedules to collect data, and explored these data using interpretative phenomenological analysis (IPA).

RESULTS

Five themes emerged about how participants were able to access help; having to reach a crisis point before accepting the need for help, overcoming feelings of shame, the importance of having an internal locus of control, finding a psychological explanation for their symptoms and having strong social support.

CONCLUSIONS

This study reported that for military personnel who accessed mental health services, there were a number of factors that supported them to do so. In particular, factors that combated internal stigma, such as being supported to develop an internal locus of control, appeared to be critical in supporting military personnel to engage in help-seeking behaviour.

Employment status in multiple sclerosis: impact of disease-specific and non-disease-specific factors

Background:

Multiple sclerosis (MS) is associated with high rates of early retirement (ER).

Objectives:

A German cohort of MS patients and healthy control subjects (HCs) were compared cross-sectionally to investigate disease- and non-disease-specific factors that are associated with employment status (ES) in MS and to identify predictors of ES in MS.

Methods:

A total of 39 ER MS patients, 48 employed MS patients, and 37 HCs completed a brief neuropsychological battery and questionnaires related to depressive symptoms, fatigue, health-related quality of life (HrQoL) and health locus of control (HLC). Neurological disability was assessed by the Expanded Disability Status Scale (EDSS) and the Multiple Sclerosis Functional Composite (MSFC).

Results:

ER compared with employed MS patients scored significantly higher in neurological disability, depressive symptoms and fatigue and significantly lower in cognitive functioning and HrQoL. Further, both groups differed with regard to age, education, disease course and duration but not in HLC. Neurological disability, age and fatigue were identified as significant predictors of ES in MS.

Conclusions:

ES in MS was associated with demographic aspects, neurological and cognitive status, depressive symptoms, fatigue and HrQoL but was not associated with HLC. Findings confirm neurological disability, age and fatigue as independent predictors of ES in MS.

The Gap in the Current Research on the Link between Health Locus of Control and Multiple Sclerosis: Lessons and Insights from a Systematic Review

Multiple sclerosis (MS) is a chronic neurological disease whose etiology has not been fully understood yet in detail. Empirical findings show how psychosocial symptoms are very important features of the clinical presentation of MS, having a deep impact on patient's quality of life, and thus psychological coping strategies may play a central role in reducing the burden of the disease and improving patient's satisfaction of life. MS progression and relapses/exacerbations are unpredictable and may depend on factors such as stressor chronicity, frequency, severity, type, and individual patient characteristics such as depression, personality, locus of control (LOC), optimism, and perceived social support. Due to its importance for health-care delivery, rehabilitation, and nursing, here, we make a systematic review on the current state-of-the-art studies concerning the relationship between LOC and MS, according to the PRISMA guidelines, and we assess the quality and the completeness of the studies using the CONSORT instrument, underpinning their limitations, and suggesting how to fill the gap in this research field.

Factors affecting anxiety in multiple sclerosis

PURPOSE

Anxiety is common in people with multiple sclerosis (MS). Little is known about the factors related to anxiety. The aim was to identify factors associated with the presence of anxiety.

METHODS

This was a cohort study. Participants were sent questionnaires to measure factors potentially related to anxiety. The factors included disability, depression, self-efficacy, locus of control, general stress, psychological distress and factors specific to MS. Participants with significant levels of anxiety, as measured by the Hospital Anxiety and Depression Scale (HADS), were compared to those who were not anxious.

RESULTS

Of the 157 participants who took part, 89 (57%) were clinically anxious. Participants who were anxious had a lower level of self-efficacy (p < 0.001), higher level of disability (p < 0.001), higher level of depression (p < 0.001) and higher level of stress (p < 0.001). The regression analysis showed that experiencing depression (χ(2) = 5.05, OR = 1.32, p < 0.05) was the only factor that significantly predicted whether someone was anxious or not, accounting for 46% of the variance.

CONCLUSION

There was a high prevalence of anxiety in people with MS. Depression, low levels of self-efficacy, disability and stress increased the likelihood of experiencing anxiety.

Locus of control, depression, and quality of life in Parkinson's Disease

People can attribute the source of control of events that involve them either to internal or external factors. Through this view, depression can be defined as a belief that one's own behavior is not effective. In case of chronic diseases, such as Parkinson's Disease, depression is more frequent than in the general population. The present study aimed to assess locus of control orientation and its relation with depression and quality of life in 30 patients with Parkinson's Disease. Results showed positive correlation between external locus orientation and depression and quality of life scores, and negative correlation between internal orientation and depression.
