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.

Positivity and Health Locus of Control: Key Variables to Intervene on Well-Being of Cardiovascular Disease Patients

Psychological well-being is a good predictor of several health outcomes in cardiovascular disease patients (adherence, quality of life, and healthy behaviors). The perception of health control and a positive orientation seem to have a beneficial effect on health and well-being. Therefore, the aim of this study was to investigate the role of the health locus of control and positivity in the psychological well-being and quality of life of cardiovascular patients. A total of 593 cardiac outpatients completed the Multidimensional Health Locus of Control Scale, the Positivity Scale and the Hospital Anxiety and Depression Scale at baseline (January 2017) and 9 m later (follow-up; n = 323). A Spearman rank correlation coefficient and a structural equation modeling approach were determined to explore the relationships between those variables both cross-sectionally and longitudinally. A cross-sectional correlation analysis at baseline revealed that the internal health locus of control and positivity were negatively associated with anxiety (rs = -0.15 and -0.44, ps < 0.01) and depression (rs = -0.22 and -0.55, ps < 0.01) and positively associated with health-related quality of life (rs = 0.16 and 0.46, ps < 0.01). Similar outcomes were found at follow-up and in longitudinal correlations. According to the path analysis, positivity was found to be negatively associated with anxiety and depression level at baseline (β = -0.42 and -0.45, ps < 0.001). Longitudinally, positivity was negatively associated with depression (β = 0.15, p < 0.01) and together with the internal health locus of control, was positively associated with health-related quality of life (β = 0.16 and 0.10, respectively, ps < 0.05). These findings suggest that focusing on the health locus of control and especially positivity may be crucial in enhancing the psychological well-being of patients in the context of cardiac care. The potential impact of these results on future interventions is discussed.

Role of health locus of control in preventing occupational decompression sickness among deep-sea fisherman divers

Background

Indigenous fisherman divers frequently experience decompression sickness (DCS). This study aimed to evaluate the associations between the level of knowledge of safe diving, beliefs in the health locus of control (HLC), and regular diving practices with DCS among the indigenous fisherman divers on Lipe island. The correlations among the level of beliefs in HLC, knowledge of safe diving and regular diving practices were evaluated also.

Method

We enrolled the fisherman divers on Lipe island and collected their demographics, health indices, levels of knowledge of safe diving, beliefs in external and internal HLC (EHLC and IHLC), and regular diving practices to evaluate the associations with the occurrence of DCS by logistic regression analysis. Pearson's correlation was used to test the correlations among the level of beliefs in IHLC and EHLC, knowledge of safe diving, and regular diving practices.

Results

Fifty-eight male fisherman divers whose mean age was 40.39 (±10.61) (range 21-57) years were enrolled. Twenty-six (44.8%) participants had experienced DCS. Body mass index (BMI), alcohol consumption, diving depth, duration of time in the sea/dive, level of beliefs in HLC and regular diving practices were significantly associated with DCS (p < 0.05). Level of belief in IHLC had a significantly strong reverse correlation with that in EHLC and a moderate correlation with level of knowledge of safe diving and regular diving practices. By contrast, level of belief in EHLC had a significantly moderate reverse correlation with level of knowledge of safe diving and regular diving practices (p < 0.001).

Conclusions

Encouraging the fisherman divers' belief in IHLC could be beneficial for their occupational safety.

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.

Psychometric properties of the Chinese version of the recovery locus of control (RLOC) Scale among patients with myocardial infarction

Aim

To translate the RLOC Scale into Chinese and test its psychometric properties in the Chinese patients with myocardial infarction (MI).

Design

A cross‐sectional design was used.

Methods

A convenience sample of 233 patients with MI who have undergone percutaneous coronary intervention and were ready for discharge were recruited in a level A tertiary hospital of Shandong Province from January 2019 to April 2019. Data were analysed using item analysis, internal consistency reliability and exploratory factor analysis.

Results

Two factors—external RLOC and internal RLOC—were extracted, accounting for 70.5% of the variance. Cronbach's alpha for the Chinese version of RLOC Scale was 0.80 and for the two factors was 0.92 and 0.76, respectively. The Chinese version of RLOC Scale showed satisfactory reliability and validity, which can be used to measure the ability of recovery locus of control in Chinese patients with MI.

Predicting Perceived Stress Related to the Covid-19 Outbreak through Stable Psychological Traits and Machine Learning Models

The global SARS-CoV-2 outbreak and subsequent lockdown had a significant impact on people's daily lives, with strong implications for stress levels due to the threat of contagion and restrictions to freedom. Given the link between high stress levels and adverse physical and mental consequences, the COVID-19 pandemic is certainly a global public health issue. In the present study, we assessed the effect of the pandemic on stress levels in N = 2053 Italian adults, and characterized more vulnerable individuals on the basis of sociodemographic features and stable psychological traits. A set of 18 psycho-social variables, generalized regressions, and predictive machine learning approaches were leveraged. We identified higher levels of perceived stress in the study sample relative to Italian normative values. Higher levels of distress were found in women, participants with lower income, and participants living with others. Higher rates of emotional stability and self-control, as well as a positive coping style and internal locus of control, emerged as protective factors. Predictive learning models identified participants with high perceived stress, with a sensitivity greater than 76%. The results suggest a characterization of people who are more vulnerable to experiencing high levels of stress during the COVID-19 pandemic. This characterization may contribute to early and targeted intervention strategies.

Health locus of control and mortality: a population-based prospective cohort study

OBJECTIVES

The objective of the study was to estimate associations between health locus of control (HLC) and mortality.

STUDY DESIGN & METHODS

The public health survey in Scania 2008 was linked to the Swedish cause of death register. In this study of 10,757 men and 12,322 women aged 18-80 years, 421 men and 235 women died during the 5.3-year follow-up. Survival analyses were conducted.

RESULTS

Respondents with only some or no internal HLC had significantly higher hazard rate ratios (HRRs) compared with respondents with high HLC. For women, the HRRs of those with low HLC did not significantly differ from the reference group after final adjustments for health-related behaviours.

CONCLUSIONS

HLC is a predictor of mortality, and this association is to an important extent mediated by health-related behaviours.

A Cultural Perspective on Functional Limitations and Well-Being

Functional limitations-difficulty in carrying out activities of daily living-have been linked to poorer well-being in Western cultures. This might be partly due to the lower personal control associated with functional limitations. However, compared with the West, in Asian cultural contexts (e.g., Japan) where agency and control are based less predominantly on individual attributes, the link between functional limitations and well-being may be weaker. Using cross-sectional probability samples from the United States and Japan (Study 1), functional limitations were associated with lower well-being in both cultures, though the association was weaker in Japan than in the United States and personal control played a mediating role. Furthermore, analyses of longitudinal data (Study 2) showed the cross-cultural patterns generally consistent with the cross-sectional analyses of Study 1, though the cultural moderation was found for fewer well-being measures. Such findings enrich our understanding of how health status and well-being are related across cultures.

Controlling the Uncontrollable: Perceptions of Balance in People With Parkinson Disease

BACKGROUND

Exercise improves balance in Parkinson disease (PD), yet the majority of people with the diagnosis are physically inactive. Insights gained from understanding how people with PD (PwPD) make sense of their symptoms and their ability to control them may inform the communication strategies and motivational approaches adopted by physical therapists. To our knowledge, no previous study has qualitatively explored how PwPD perceive the concept of balance and the beliefs they hold concerning their ability to affect balance.

OBJECTIVE

This study aimed to explore the meaning of balance for PwPD and the beliefs they hold regarding their ability to influence their balance in everyday life.

DESIGN

The design was a qualitative study with an inductive approach.

METHODS

In-depth interviews were conducted with 18 participants with PD (age range 46-83 years, Hoehn and Yahr range 1-4), and transcripts were analyzed using qualitative content analysis.

RESULTS

Five main themes emerged from the analysis: remaining in control over the body, adapting behavior to deal with uncertainty, directing focus to stay 1 step ahead, resilience as a defense, and exercise beliefs and reservations. Interpretation of the underlying patterns in the main themes yielded the overarching theme of focus and determination to regain control over shifting balance.

CONCLUSIONS

The concept of balance was perceived as both bodily equilibrium and mind-body interplay and was described in the context of remaining in control over one's body and everyday life. Cognitive resources were utilized to direct focus and attention during balance-challenging situations in a process involving internal dialogue. Even participants who did not express beliefs in their ability to affect balance through exercise used psychological resilience to counter the challenges of impaired balance.

Potential effects of multimodal psychosomatic inpatient treatment for patients with functional vertigo and dizziness symptoms - A pilot trial

OBJECTIVES

Functional vertigo and dizziness (VD) are frequent and severely distressing complaints that are often described as hard to treat. Our aim was to provide preliminary data on potential effects of multimodal psychosomatic inpatient therapy for patients with functional VD symptoms in reducing vertigo-related handicap and related psychopathology, and to evaluate the role of symptom burden and body-related locus of control in predicting vertigo-related handicap at follow-up.

DESIGN

We conducted an uncontrolled clinical pilot trial.

METHODS

We included data of n = 72 inpatients with functional VD as a primary symptom and various psychopathological and/or physical comorbidities admitted for multimodal psychosomatic inpatient treatment. Patients completed self-report questionnaires assessing vertigo-related handicap (VHQ), somatization (PHQ-15), depression (BDI-II), anxiety (BAI), health-related quality of life (HRQOL; SF-36), and body-related locus of control (KLC) at admission (T0), discharge (T1), and 6 months after discharge (T2).

RESULTS

We observed medium effects for the change of vertigo-related handicap (T0-T1: g = -0.60, T0-T2: g = -0.67) and small effects for the change of somatization (T0-T1: g = -0.29, T0-T2: g = -0.24), mental HRQOL (T0-T1: g = 0.43, T0-T2: g = 0.49), and depression (T0-T1: g = -0.41, T0-T2: g = -0.28) from admission to discharge and admission to follow-up. Body-related locus of control did not predict vertigo-related handicap at follow-up.

CONCLUSIONS

Findings provide preliminary evidence for the beneficial role of psychosomatic inpatient treatment for patients with functional VD symptoms. Potentially relevant predictors of outcome at follow-up are discussed.

PRACTITIONER POINTS

The change of vertigo-related handicap and related variables through multimodal psychosomatic inpatient treatment was evaluated in a clinical pilot trial in patients with functional vertigo and dizziness. We observed medium effects for the change of vertigo-related handicap and small effects for the change of somatization, mental health-related quality of life, and depression. Internal body-related locus of control at admission did not predict vertigo-related handicap at follow-up.

The Role of Health Locus of Control in Pain Intensity Outcome of Conservatively and Operatively Treated Hand Surgery Patients

PURPOSE

Psychological factors have shown to be associated with treatment outcomes in hand injury patients. This study aimed to investigate the role of health locus of control (HLOC) and its dimensions internal, social-external, and fatalistic-external HLOC in treatment outcomes of hand injury patients.

METHOD

One hundred thirty-two consecutive patients of a tertiary center for hand surgery undergoing treatment for acute hand injury or degenerative hand problems were included in this study. Pretreatment levels of depression, anxiety, HLOC, and pain intensity were measured, along with pain intensity levels at 4-month follow-up. Hierarchical regression analyses were calculated to test for moderation effects of the HLOC dimensions on the relationship between pretreatment and follow-up pain intensity.

RESULTS

Controlling for age, gender, treatment modality, source of hand pain, and depressive symptoms, a moderation effect emerged (β = - 0.16, p < 0.05), such that among patients higher in initial pain intensity, those lower in social-external HLOC experienced higher pain intensity at follow-up compared to those with high social-external HLOC. Internal HLOC and fatalistic-external HLOC did not moderate the effect of initial pain intensity on pain intensity at follow-up.

CONCLUSION

Hand injury patients suffering greater initial pain intensity who also had lower versus higher social-external HLOC experienced less favorable treatment outcome. This finding suggests that if patients with high initial pain succeed in transferring perceived health control to professionals and to gain confidence in treatment and clinicians, treatment outcome could be improved in hand surgery.

Comparison of three scales to evaluate personality traits in Parkinson's disease: which one to use?

BACKGROUND

Personality traits have gained interest in the field of disability and stress, because they may either prompt or deny compliance. They can also foster motivation and influence outcome. Parkinson disease (PD) is a disabling and stressful condition that requires coping strategies and rehabilitation plans. Three constructs and their relative scales have been a matter of investigation, namely dispositional optimism (DO), locus-of-control (LOC), and sense-of-coherence (SOC).

AIM

The present study compared the psychometric properties of three constructs in Parkinson's disease (PD). The health-related variables were: emotional distress (ED), quality of life (HR-QoL) and activities of daily living (ADL). The final objective was to provide guidance on scale selection to be implemented in clinical protocols.

DESIGN

A cross sectional study.

SETTING

Community-based general physicians.

POPULATION

Participants with PD (N.=84) from community-based general physicians.

METHODS

PD patients completed 3 self-report scales, namely Life Orientation Test-Revised (LOT-R, measuring Dispositional Optimism), Internal and External Locus Of Control (LOC-int. LOC-ext) and Sense of Coherence (SOC). All participants had magnetic resonance imaging. The MDS-UPDRS and the Barthel Scale were compiled by the investigator with the assistance of a caregiver.

RESULTS

LOC-ext was the only scale to be associated with PD severity and disability (P<0.05). A higher level of LOC-ext was also associated with a higher level of ED (P<0.005). LOT-R was inversely associated with ED. Subjects in the highest tertile had a 41% lower ED (P<0.001). SOC was also inversely associated with degree of ED. Subjects in the highest tertile have a 44% lower ED (P<0.01). Moreover, HR-QoL is associated with several parameters, but LOT-R is the one with the strongest association (P<0.001).

CONCLUSIONS

DO and SOC are predictive of important end-points, namely HR-QoL and ED. DO is even better under this respect. Conversely, those clinicians who are more interested in motor problems may find LOC more suitable. DO may be the most efficient construct to use in PD because of its favorable psychometric properties.

CLINICAL REHABILITATION IMPACT

DO, LOC and SOC are constructs to be implemented in both research and clinical PD protocols. It is recommended to implement these, because they have predictive value especially when HR-QoL and ED are studied.

Health locus of control: Its relationship with medication adherence and medication wastage

BACKGROUND

Non-adherence is a significant factor contributing to medication wastage. Whilst there is some evidence on the influence of patients' health locus of control in relation to adherence, there has been little inquiry into its relationship with mediation wastage.

OBJECTIVES

To determine the relationship between medication adherence and health locus of control as well as medication wastage and health locus of control in patients with chronic conditions.

METHODS

Outpatients having a diagnosis of asthma, cardiovascular conditions, or diabetes participated in a cross-sectional study employing a self-administered questionnaire. The questionnaire determined presence of unused medication (wastage), adherence using 'Tool for Adherence Behaviour Screening' (TABS), and health locus of control using 'Multidimensional Health Locus of Control' (MHLC) scale Form C. Logistic regression was performed to ascertain the effects of MHLC and demographics in relation to adherence and wastage. MHLC beliefs were divided into 8 types of health locus of control. One-Way ANOVA was used to assess differences between conditions and belief types. P-values ≤ .05 were considered significant.

RESULTS

There were 330 patients recruited (58% male; age, mean±(SD): 61 ± 15 years; 110 asthma, 110 cardiovascular, 110 diabetes). In terms of health locus of control, females had higher 'doctors' beliefs (p = .054) and significantly lower 'other people' beliefs (p = < .0005). Lower 'chance' beliefs (p = .016) were associated with adherence. Lower 'doctors' beliefs and higher 'other people' beliefs were significantly associated with wastage (p = < .0005). There was a significant difference in adherence (p = < .0005) and in wastage (p = .002) between the eight types of health control. 'Yea-sayers' had the least presence of unused medication, followed by 'pure internal' believers. 'Pure powerful others external' had the highest presence of unused medication.

CONCLUSIONS

Healthcare professionals should take into account patients' health locus of control beliefs whilst conducting an intervention with patients; this can impact positively medication adherence and minimisation of medication wastage.
