Predictors of exercise in individuals with schizophrenia: A test of the transtheoretical model of behavior change

Effect of Cross Theoretical Model of Behaviour Change and Motivation Interview on Self-Management Behaviour

Objective

To evaluate the effects of a trans-theoretical model (TTM) of behavioural change plus motivational interviewing on self-management behavior and quality of life (QoL) in patients with intracranial aneurysm.

Methods

A total of 94 patients with intracranial aneurysm treated in the First Affiliated Hospital of Wenzhou Medical University from 2019 to 04/2021-04 were retrospectively analyzed. Among them, 49 patients used TTM + motivational interview as the observation group (Obs group), and 45 patients used the traditional method as the control group (Con group). The Self-Management Behavior Scale for Patients with Intracranial Aneurysm was used for analyzing the changes in the self-management behavior of the two groups of patients, and the MOS 36-item Short Form Health Survey (SF-36) was used to analyze the changes in the QoL of the patients. The incidence of adverse events after 6 months of intervention was counted. In addition, the Barthel Index (BI) and Montreal Cognitive Assessment Scale (MOCA) were used to evaluate the recovery effects of patients. Logistic regression was conducted for analyzing the risk factors of adverse cerebrovascular events.

Results

After treatment, the Con group got lower self-management behavior score than the Obs group (P < 0.05), and also got lower SF-36 scores, BI, and MOCA scores than the Obs group (P < 0.05). Age and a history of hypertension were independent risk factors for adverse events. The Hosmer-Lemeshow test was adopted for testing the goodness of fit of the regression equation (P=0.903). With the established model, the area under the receiver operating characteristic curve for predicting adverse events in patients with intracranial aneurysm was determined to be 0.851, indicating that the model performed well as a risk prediction model.

Conclusion

TTM + motivational interviewing can help improve the self-management behavior and QoL of patients with intracranial aneurysm without increasing the occurrence of adverse events.

Clinical, physical, physiological, and cardiovascular risk patterns of adults with schizophrenia: CORTEX-SP study: Characterization of adults with schizophrenia

Schizophrenia (SP) is a severe mental illness with high rates of premature morbidity and mortality, associated with an unhealthy lifestyle and the side effects of drug treatment. The aims of the study were: 1) to determine some key physical, physiological and biochemical markers of health status, including sleep quality, in adults (42±10 yr) with SP (n=126), 2) to estimate cardiovascular risk (CVR), and 3) to compare all studied variables with a healthy control (HC) population (n=30). Assessment was based on body composition, blood pressure, cardiorespiratory condition, sleep quality with triaxial accelerometry for eight days and biochemical analysis. Participants with SP showed a cardiovascular risk profile including "overweight metabolically abnormal", low cardiorespiratory fitness, and impairment of ventilatory efficiency. Although individuals with SP slept more compared to HC, similar sleep efficiency was shown by both groups, but with significantly higher levels of wake after sleep onset by SP. The assessment of CVR revealed significantly higher values in SP (moderate risk) compared to HC (low risk) regardless of the estimation system. The identification of specific clinical, physical, and physiological CVR profiles in SP illness compared to healthy people strongly suggests targeting a comprehensive approach including non-pharmacological interventions.

Determinants of Physical Health Self-Management Behaviours in Adults With Serious Mental Illness: A Systematic Review

Behavioural interventions can support the adoption of healthier lifestyles and improve physical health outcomes, but it is unclear what factors might drive success of such interventions in people with serious mental illness (SMI). We systematically identified and reviewed evidence of the association between determinants of physical health self-management behaviours in adults with SMI. Data about American Association of Diabetes Educator's Self-Care Behaviours (AADE-7) were mapped against the novel Mechanisms of Action (MoA) framework. Twenty-eight studies were included in the review, reporting evidence on 104 determinant-behaviour links. Beliefs about capabilities and beliefs about consequences were the most important determinants of behaviour, especially for being physically active and healthy eating. There was some evidence that emotion and environmental context and resources played a role in determining reducing risks, being active, and taking medications. We found very limited evidence associated with problem solving, and no study assessed links between MoAs and healthy coping. Although the review predominantly identified evidence about associations from cross-sectional studies that lacked validated and objective measures of self-management behaviours, these findings can facilitate the identification of behaviour change techniques with hypothesised links to determinants to support self-management in people with SMI.

Factors associated with regular physical activity participation among people with severe mental ill health

PURPOSE

People with severe mental ill health (SMI) are less physically active and more sedentary than the general population. There is limited research investigating the correlates of physical activity (PA) in people with SMI impeding the development of successful interventions. This study aimed to assess the factors associated with regular participation of PA among a large sample of people with SMI.

METHODS

The data for this study were collected from the 'Closing the Gap: Lifestyle Health and Wellbeing' (HWB) cohort that collected data through self-administered questionnaire from participants with SMI. Self-reported participation in regular PA was the main outcome variable. Potential predictors of PA were grouped as demographic, biological, psychological and behavioural variables. Multivariable logistic regressions were conducted considering PA participation as the dependent variable adjusted for possible correlated predictors.

RESULTS

In total, 3287 people with SMI [mean (SD) age 47.7 (14.58) years, 59% male] were included; 38% reported undertaking regular PA and 61% wanted to undertake more physical activity. Multivariable logistic regressions showed that the following factors were associated with undertaking more regular PA: being male, aged 18-65 years, having a body mass index between 18.5 and 30 kg/m², having better self-perceived general health condition, not having a health problem that limits activity, giving higher importance to maintain a healthy lifestyle, and eating more fruit and vegetables.

CONCLUSIONS

Having a better self-perceived general health and placing importance on maintaining a healthy lifestyle were important predictors of regular PA. Lifestyle interventions targeting increased PA among people with SMI should be shaped by their health perception and informed by their needs.

Lifestyle Interventions and Prevention of Suicide

Over the past years, there has been a growing interest in the association between lifestyle psychosocial interventions, severe mental illness, and suicide risk. Patients with severe mental disorders have higher mortality rates, poor health states, and higher suicide risk compared to the general population. Lifestyle behaviors are amenable to change through the adoption of specific psychosocial interventions, and several approaches have been promoted. The current article provides a comprehensive review of the literature on lifestyle interventions, mental health, and suicide risk in the general population and in patients with psychiatric disorders. For this purpose, we investigated lifestyle behaviors and lifestyle interventions in three different age groups: adolescents, young adults, and the elderly. Several lifestyle behaviors including cigarette smoking, alcohol use, and sedentary lifestyle are associated with suicide risk in all age groups. In adolescents, growing attention has emerged on the association between suicide risk and internet addiction, cyberbullying and scholastic and family difficulties. In adults, psychiatric symptoms, substance and alcohol abuse, weight, and occupational difficulties seems to have a significant role in suicide risk. Finally, in the elderly, the presence of an organic disease and poor social support are associated with an increased risk of suicide attempt. Several factors may explain the association between lifestyle behaviors and suicide. First, many studies have reported that some lifestyle behaviors and its consequences (sedentary lifestyle, cigarette smoking underweight, obesity) are associated with cardiometabolic risk factors and with poor mental health. Second, several lifestyle behaviors may encourage social isolation, limiting the development of social networks, and remove individuals from social interactions; increasing their risk of mental health problems and suicide.

A review and study of aspirin utilization for the primary prevention of cardiovascular events in a psychiatric population

In April 2016, the US Preventive Service Task Force (USPSTF) updated the aspirin guidelines for the primary prevention of cardiovascular disease (CVD) and colorectal cancer. This review assesses the importance of appropriate use of aspirin for the primary prevention of CVD and, specifically, how individuals with psychiatric disorders may benefit from such use. This study examined how current prescribing practices of aspirin in a state psychiatric hospital align with these new guidelines and how inappropriate prescribing may jeopardize patient safety. A retrospective chart review of 93 patients was performed to evaluate whether aspirin therapy would be recommended for primary prevention of CVD based on the new USPSTF guidelines. A secondary analysis of these data was performed using the 2009 USPSTF recommendations to strengthen the assumption that practitioners were no longer using the old guidelines. Drug interactions between aspirin and concurrently prescribed pharmacotherapy were classified based on of severity, and the past events of bleeding were quantified. Based on the 2016 guidelines, 25 of the 93 patients included in this study were identified as potential candidates who would benefit from aspirin use for the primary prevention of CVD; of whom 22 (88%) were not prescribed aspirin. The remaining 68 patients did not meet the criteria for aspirin use for primary prevention, although 11 (16.2%) of these patients were taking low-dose aspirin. Based on the 2009 guidelines, 49 of the 93 patients included in our study would have been identified as potential candidates who would benefit from the use of aspirin for the primary prevention of CVD; 41 (83.7%) of whom were not prescribed aspirin. The remaining 44 patients did not meet the previous criteria for aspirin use for primary prevention, although six (13.6%) of these individuals were taking low-dose aspirin daily. The results above indicate a difference between prescribing practices of aspirin use for the primary prevention of CVD. We identified a similar rate of underuse; however, there was a slight increase in the appropriate prescribing according to the 2016 guidelines compared with the 2009 guidelines (88 vs. 83.7%, respectively). Also, there was a higher incidence of unnecessary prescribing (overutilization) of aspirin for the primary prevention of CVD in 2016 compared with 2009 despite the more restrictive criteria (and smaller candidate pool) published in these newer guidelines. There were 47 drug interactions identified when patients' aspirin and concurrent medication regimens were reviewed for our entire sample population. These interactions could potentially lead to an adverse drug reaction in the future. Our safety analysis revealed that none of the patients who were prescribed aspirin had any bleeding events while on therapy within the period of this study. Inappropriate omission of aspirin (underutilization) was more prevalent in our psychiatric institution than overutilization; however, the overall percentage of both underuse and overuse were greater when patients were evaluated according to the 2016 guidelines and then compared with the 2009 statistics. Overutilization did not pose a serious risk for those on aspirin therapy in this sample, as there were no major episodes of bleeding. However, future harm from aspirin still exists based on the significant number of major and moderate potential drug interactions with aspirin and the increased risk of decreased adherence to critical psychiatric medications due to increased pill burden and regimen complexity. Our findings demonstrate that there is an opportunity to educate prescribers on the updated 2016 USPSTF guidelines to improve preventive care and patient safety, which include harm reduction by initiating aspirin in those who are at a risk of cardiovascular events, continuing aspirin in those who are currently receiving aspirin appropriately, and discontinuing aspirin in those who are not considered to be at a high risk of CVD and who may also be at a risk of experiencing an increased risk of bleeding.

[Physical activity in patients with schizophrenia: From neurobiology to clinical benefits]

Schizophrenia is a severe chronic mental disorder that mainly manifests by positive symptoms, negative symptoms, disorganized behavior and thought and cognitive impairments. Taken together, these symptoms have substantial impact on quality of life, well-being and functional outcome. Patients with schizophrenia have dramatically higher levels of cardiovascular and metabolic morbidity than the general population due to poor physical fitness and to sedentary lifestyle. They have a reduced life expectancy, and an excess mortality being two or three times more than that in the general population. Moreover, despite major therapeutic advances in the overall management of these patients, some symptomatic dimensions, and more specifically the negative and cognitive ones, remain to be resistant to the usual pharmacological approaches. Moreover, antipsychotics can also reinforce the global cardiovascular risk due to side effects and low neurometabolic tolerance. The benefits of physical activity on health are now well described in the general population and in many medical diseases. More recently, physical activity has also found its place as an adjuvant therapy in severe mental illnesses, particularly in schizophrenia. In the literature physical activity programs, in addition to pharmacological treatments, appear to be feasible in patients and improve both physical and mental health as well as functional outcome. Clinical benefits of physical activity would be underpinned by biological and cerebral mechanisms, which remain unclear. In this review, we propose to present a state of the art and to present an update of the interests of physical activity in the management of patients with schizophrenia. We emphasize the clinical benefits of physical activity regarding the different symptomatic dimensions and its impact specifically on cognitive deficits. Finally, we describe the various underlying pathophysiological mechanisms in particular in the neurobiological, cerebral and physiological fields. We then discuss the barriers, facilitators and motivating factors towards physical activity to enhance health promotion initiatives, to optimize resource allocation when delivering physical activity programs in clinical practice, and to maximize physical activity participation. Physical activity appears to be an original and novel adjunctive therapeutic approach in the management of patients with schizophrenia and would both reduce schizophrenic symptoms and act like pro-cognitive therapy, improve quality of life and long-term functioning in daily life and reduce cardiovascular comorbidities. However, efforts are still needed to increase the motivating factors and adherence towards physical activity participation for people with schizophrenia.

Using the transtheoretical model to predict physical activity level of overweight adults with serious mental illness

Although physical activity (PA) is recommended for individuals with serious mental illness (ISMI), most of them are inactive or insufficiently active. The transtheoretical model (TTM) has been proposed to explain the motivational factors associated with PA however, there is little evidence of its applicability to ISMI. So, the objective was to analyse whether TTM components are related to PA in overweight ISMI. In this cross-sectional study, participants completed the Global Physical Activity Questionnaire to assess their PA level and TTM components: stages of change (SOC), decisional balance (pros and cons), self-efficacy and processes of change (POC; experiential and behavioural). 43 overweight ISMI (27 males, mean age 29.0 ± 6.64, mean BMI 31.91 ± 5.10kg/m², 30% with schizophrenia, and 44% inactive), referred to a PA programme were recruited. PA was positively correlated with POC and perceived pros, with TTM constructs accounting for 14.5% of PA variance. Mean level of behavioural POC and perceived pros were higher in physically active than in inactive participants. So, this study confirms that TTM components are associated with PA in overweight ISMI. Therefore, the TTM should be considered when planning PA interventions for ISMI.

The Utility of the Health Action Process Approach Model for Predicting Physical Activity Intentions and Behavior in Schizophrenia

Research is needed to develop evidence-based behavioral interventions for preventing and treating obesity that are specific to the schizophrenia population. This study is the precursor to such intervention research where we examined the utility of the social cognitions outlined within the Health Action Process Approach (HAPA) model for predicting moderate to vigorous physical activity (MVPA) intentions and behavior among individuals with schizophrenia or schizoaffective disorder. A prospective cohort design [baseline (T1), week 2 (T2), and week 4 (T3)] was used to examine the HAPA constructs and MVPA across a sample of 101 adults (Mage = 41.5 ± 11.7 years; MBMI = 31.2 ± 7.8 kg/m2; 59% male). Two hierarchical regression analyses were conducted controlling for age, gender, BMI, and previous self-reported MVPA. In the first regression, intentions at T1 were regressed onto the T1 motivational HAPA constructs (risk perception, affective attitudes, task self-efficacy) and social support; MVPA status (meeting vs. not meeting the MVPA guidelines) assessed via accelerometry at T3 was regressed onto T1 social support and intentions followed by T2 action and coping planning, and maintenance self-efficacy in the second analysis. Overall, the motivational and social support variables accounted for 28% of the variance in intentions, with affective attitudes (β = 0.33, p < 0.01) and task self-efficacy (β = 0.25, p < 0.05) exhibiting significant, positive relationships. For MVPA status, the model as a whole explained 39% of the variance, with the volitional HAPA constructs explaining a non-significant 3% of this total variance. These findings suggest a need for interventions targeting self-efficacy and affective attitudes within this clinical population.

Physical activity and anomalous bodily experiences in patients with first-episode schizophrenia

BACKGROUND

Low physical activity is strongly correlated with metabolic syndrome (MetS) and poor physical health. Although the prevalence of MetS is high in patients with first-episode schizophrenia (FES), little is still known about the level of and possible barriers for physical activity in FES.

AIM

The purpose of the study was to compare physical activity in patients with FES with healthy controls; to investigate changes in physical activity over 1 year of follow-up; and to explore the correlations of physical activity and anomalous bodily experiences reported by patients with FES.

METHODS

Both physical activity and aerobic fitness were measured. Anomalous bodily experiences were measured by selected items from the Examination of Anomalous Self-Experience and The Body Awareness Scale. Psychopathological data comprising negative and positive symptoms and data on psychotropic medication were obtained from medical records of all patients.

RESULTS

Physical activity and aerobic fitness was significantly lower in patients with FES compared with healthy controls (p < 0.001). Over 1 year of follow-up patients had lower physical activity and aerobic fitness. Patients with more severe anomalous bodily experiences had significantly lower physical activity compared with patients with fewer such experiences (p = 0.030). In linear regression analyses only negative symptoms were significantly correlated with low physical activity (β = -0.88; 95% confidence interval = -1.48 to -0.29; p < 0.001).

CONCLUSION

Physical activity and aerobic fitness is low in patients with FES. Both anomalous bodily experiences and negative symptoms are significantly correlated with low physical activity.

Exercise Improves Clinical Symptoms, Quality of Life, Global Functioning, and Depression in Schizophrenia: A Systematic Review and Meta-analysis

BACKGROUND

Physical exercise may be valuable for patients with schizophrenia spectrum disorders as it may have beneficial effect on clinical symptoms, quality of life and cognition.

METHODS

A systematic search was performed using PubMed (Medline), Embase, PsychInfo, and Cochrane Database of Systematic Reviews. Controlled and uncontrolled studies investigating the effect of any type of physical exercise interventions in schizophrenia spectrum disorders were included. Outcome measures were clinical symptoms, quality of life, global functioning, depression or cognition. Meta-analyses were performed using Comprehensive Meta-Analysis software. A random effects model was used to compute overall weighted effect sizes in Hedges' g.

RESULTS

Twenty-nine studies were included, examining 1109 patients. Exercise was superior to control conditions in improving total symptom severity (k = 14, n = 719: Hedges' g = .39, P < .001), positive (k = 15, n = 715: Hedges' g = .32, P < .01), negative (k = 18, n = 854: Hedges' g = .49, P < .001), and general (k = 10, n = 475: Hedges' g = .27, P < .05) symptoms, quality of life (k = 11, n = 770: Hedges' g = .55, P < .001), global functioning (k = 5, n = 342: Hedges' g = .32, P < .01), and depressive symptoms (k = 7, n = 337: Hedges' g = .71, P < .001). Yoga, specifically, improved the cognitive subdomain long-term memory (k = 2, n = 184: Hedges' g = .32, P < .05), while exercise in general or in any other form had no effect on cognition.

CONCLUSION

Physical exercise is a robust add-on treatment for improving clinical symptoms, quality of life, global functioning, and depressive symptoms in patients with schizophrenia. The effect on cognition is not demonstrated, but may be present for yoga.

Motivation for physical activity and exercise in severe mental illness: A systematic review of cross-sectional studies

Individuals with severe mental illness (SMI) are less physically active than the general population. One important barrier contributing to this inactivity is lack of motivation. The aim of this paper is to systematically review all cross-sectional literature on motivation for physical activity among people with SMI and to use the results as basis for guidance on how mental health nurses can facilitate motivation for physical activity. Systematic searches of seven databases were conducted from database inception to February 2015. Studies were eligible if they included participants with SMI and reported data on motivation for physical activity. In total, 21 articles were included and over half them were published in 2011 or later. The present results indicate preliminary evidence of how the motivational processes do not differ between individuals with SMI and the general population, and that they are independent of diagnosis, medication, age, gender, and body mass index. Results from the current systematic review can give some tentative guidance on how to facilitate motivation for physical activity within mental health-care. However, there is still a great need for developing and examining practical strategies that can enhance adoption and adherence of physical activity among people with SMI.

Running for your life: A review of physical activity and cardiovascular disease risk reduction in individuals with schizophrenia

Individuals with schizophrenia have a greater risk for cardiometabolic risk factors (e.g. central obesity, insulin resistance, hypertension and dyslipidaemia), cardiovascular diseases and mortality. This risky profile may be explained by the adverse effects of antipsychotic medications and an unhealthy lifestyle (e.g. smoking, poor nutrition and low physical activity). In the general population, physical activity has been shown to be the optimal strategy to improve both cardiometabolic parameters and cardiorespiratory fitness levels. Accordingly, an emerging literature of non-pharmacological interventions (e.g. cognitive behavioural therapy, diet and physical activity) has been studied in individuals with schizophrenia. Therefore, the purpose of this review was 1) to conduct a critical literature review of non-pharmacological interventions that included some kind of physical activity (including supervised and unsupervised exercise training) and target cardiometabolic risk factors in individuals with schizophrenia. 2) To describe the contribution of physical activity alone by reviewing trials of supervised exercise training programmes only. A literature review via systematic keyword search for publications in Medline, PubMed, Embase and PsycINFO was performed. Many non-pharmacological interventions are efficient in reducing cardiovascular disease risk factors when combined with physical activity. Supervised physical activity has been successful in decreasing cardiovascular disease risk, and aerobic interval training appears to provide more benefits by specifically targeting cardiorespiratory fitness levels. In conclusion, physical activity is an effective strategy for addressing cardiovascular disease risk in individuals with schizophrenia. Long-term studies are needed to evaluate the feasibility and impact of exercise training programmes in individuals with schizophrenia.
