Development of a short form of the Cardiac Distress Inventory.

BACKGROUND: Cardiac distress may be viewed as a persistent negative emotional state that spans multiple psychosocial domains and challenges a patient's capacity to cope with living with their heart condition. The Cardiac Distress Inventory (CDI) is a disease-specific clinical assessment tool that captures the complexity of this distress. In busy settings such as primary care, cardiac rehabilitation, and counselling services, however, there is a need to administer briefer tools to aid in identification and screening. The aim of the present study was to develop a short, valid screening version of the CDI. METHODS: A total of 405 participants reporting an acute coronary event in the previous 12 months was recruited from three hospitals, through social media and by direct enrolment on the study website. Participants completed an online survey which included the full version of the CDI and general distress measures including the Kessler K6, Patient Health Questionnaire-4, and Emotion Thermometers. Relationship of the CDI with these instruments, Rasch analysis model fit and clinical expertise were all used to select items for the short form (CDI-SF). Construct validity and receiver operating characteristics in relation to the Kessler K6 were examined. RESULTS: The final 12 item CDI-SF exhibited excellent internal consistency indicative of unidimensionality and good convergent and discriminant validity in comparison to clinical status measures, all indicative of good construct validity. Using the K6 validated cutoff of ≥ 18 as the reference variable, the CDI-SF had a very high Area Under the Curve (AUC) (AUC = 0.913 (95% CI: 0.88 to 0.94). A CDI-SF score of ≥ 13 was found to indicate general cardiac distress which may warrant further investigation using the original CDI. CONCLUSION: The psychometric findings detailed here indicate that the CDI-SF provides a brief psychometrically sound screening measure indicative of general cardiac distress, that can be used in both clinical and research settings.

The cardiac distress inventory: A new measure of psychosocial distress associated with an acute cardiac event.

BACKGROUND: Many challenges are posed by the experience of a heart attack or heart surgery which can be characterised as 'cardiac distress'. It spans multiple psychosocial domains incorporating patients' responses to physical, affective, cognitive, behavioural and social symptoms and experiences related to their cardiac event and their recovery. Although some measures of the psychological and emotional impacts of a cardiac event exist, none provides a comprehensive assessment of cardiac distress. To address this gap, the study aimed to develop a Cardiac Distress Inventory (CDI) using best practice in instrument design. METHOD: An item pool was generated through analysis of cognate measures, mostly in relation to other health conditions and through focus group and individual review by a multidisciplinary development team, cardiac patients, and end-users including cardiac rehabilitation co-ordinators. The resulting 144 items were reduced through further reviews to 74 for testing. The testing was carried out with 405 people recruited from three hospitals, through social media and by direct enrolment on the study website. A two-stage psychometric evaluation of the 74 items used exploratory factor analysis to extract the factors followed by Rasch analysis to confirm dimensionality within factors. RESULTS: Psychometric analysis resulted in the identification of 55 items comprising eight subscales, to form the CDI. The subscales assess fear and uncertainty, disconnection and hopelessness, changes to roles and relationships, overwhelm and depletion, cognitive challenges, physical challenges, health system challenges, and death concerns. Validation against the Kessler 6 supports the criterion validity of the CDI. CONCLUSION: The CDI reflects a nuanced understanding of cardiac distress and should prove to be a useful clinical assessment tool, as well as a research instrument. Individual subscales or the complete CDI could be used to assess or monitor specific areas of distress in clinical practice. Development of a short form screening version for use in primary care, cardiac rehabilitation and counselling services is warranted.

Does coping style mediate the relationship between knowledge and psychosocial outcomes in women with atrial fibrillation?

Introduction: In patients affected by atrial fibrillation (AF) disease-specific knowledge and coping style may be associated with psychosocial well-being. This study aimed to determine if coping style (problem-focused, emotion-focused, avoidance-focused) mediated the relationship between patient knowledge and three psychosocial outcomes (anxiety, depression and life satisfaction). Methods: In 2021 a total of 188 women with reported AF, and ages ranging from 18 to 83 years (mean 48.7, sd 15.5 years), completed an online questionnaire consisting of sociodemographic, clinical and AF knowledge questions and psychosocial instruments (Anxiety and depression, the Hospital Anxiety and Depression (HADS) scale; life satisfaction, Satisfaction With Life Scale (SWLS); and coping style (Brief COPE). Using Jamovi statistical software three individual mediational models (for anxiety, depression and life satisfaction) were constructed assessing the direct and indirect relationships between knowledge, coping style and each psychosocial outcome. Age was a covariate in each model. Results: The mediation analyses demonstrated significant direct negative associations between AF knowledge and HADS anxiety and depression and positive associations with SWLS. There were also direct associations between each of the three coping styles and the three psychosocial outcomes. There were significant indirect effects of coping style between AF knowledge and each of the three outcomes confirming partial mediation effects. Discussion: These findings highlight the crucial role of coping style in mediating the association between AF knowledge and psychosocial outcomes. As such, interventions aimed at increasing patient knowledge of AF may be more effective if adaptive problem-solving coping strategies are also demonstrated to these patients. Additionally, modification of maladaptive coping strategies as part of the psychological management of patients with AF is highly recommended.

Socioecological factors influencing physical activity engagement for women across the menopausal transition: a systematic review.

IMPORTANCE: Physical activity during menopause can be effective in reducing the physiological changes associated with reproductive aging that increase risks for noncommunicable diseases, yet many women do not meet the recommendations for physical activity. OBJECTIVE: This study aimed to synthesize factors influencing physical activity for women across menopausal transition phases using a socioecological approach. EVIDENCE REVIEW: The Preferred Reporting Items for Systematic Reviews and Meta-Analysis was used to systematically search 10 databases between 2001 and 2021. A comprehensive search strategy was used to identify studies on physical activity of women in various stages of menopause. A socioecological model was used to categorize the reported barriers and enablers. FINDINGS: Twenty studies met the inclusion criteria. The findings highlight several intrapersonal barriers such as existing health complaints versus enablers such as awareness of the health benefits of physical activity during menopause. Ensuring women's safety, preventing injury, and enhancing exercise self-efficacy were important components of programs. Social support was also an important enabler of women's engagement in activities. CONCLUSIONS AND RELEVANCE: Several barriers and enablers were identified and can inform practitioners and future interventions to encourage physical activity among women in various stages of menopause. For instance, when encouraging physical activity during menopause, practitioners should consider other health complaints, safety, and injury prevention while discussing the benefits of physical activity related to managing menopausal symptoms. There was a lack of theoretically informed studies exploring the barriers and enablers to physical activity for women in various stages of menopause; thus, research designs may not have fully accounted for influences. Future research that combines socioecological and individual theories of behavior is needed to comprehensively understand the complexity of physical activity among women across the menopausal transition.

Unraveling the Complexity of Cardiac Distress: A Study of Prevalence and Severity.

Introduction: While much research attention has been paid to anxiety and depression in people who have had a recent cardiac event, relatively little has focused on the broader concept of cardiac distress. Cardiac distress is a multidimensional construct that incorporates but extends beyond common mood disorders such as anxiety and depression. In the present study we assessed the prevalence, severity and predictors of a broad range of physical, affective, cognitive, behavioral and social symptoms of cardiac distress. This is the first study to investigate cardiac distress in this comprehensive way. Method: A sample of 194 patients was recruited from two hospitals in Australia. Eligible participants were those who had recently been hospitalized for an acute cardiac event. Data were collected at patients' outpatient clinic appointment ~8 weeks after their hospital discharge. Using a questionnaire developed through a protocol-driven 3-step process, participants reported on whether they had experienced each of 74 issues and concerns in the past 4 weeks, and the associated level of distress. They also provided sociodemographic and medical information. Regression analyses were used to identify risk factors for elevated distress. Results: Across the 74 issues and concerns, prevalence ratings ranged from a high of 66% to a low of 6%. The most commonly endorsed items were within the domains of dealing with symptoms, fear of the future, negative affect, and social isolation. Common experiences were "being physically restricted" (66%), "lacking energy" (60%), "being short of breath" (60%), "thinking I will never be the same again" (57%), and "not sleeping well" (51%). While less prevalent, "not having access to the health care I need," "being concerned about my capacity for sexual activity," and "being unsupported by family and friends" were reported as highly distressing (74, 64, and 62%) for those experiencing these issues. Having a mental health history and current financial strain were key risk factors for elevated distress. Conclusion and Implications: Specific experiences of distress appear to be highly prevalent in people who have had a recent cardiac event. Understanding these specific fears, worries and stressors has important implications for the identification and management of post-event mental health and, in turn, for supporting patients in their post-event cardiac recovery.

Kindergarten attendance may reduce developmental impairments in children: results from the Bavarian Pre-School Morbidity Survey.

BACKGROUND: The relative risks and benefits of children attending kindergarten or pre-school remain uncertain and controversial. We used data from the Bavarian Pre-School Morbidity Survey (BPMS) to look at the prevalence of developmental impairments in pre-school children entering primary school and to assess if these were correlated with the duration of kindergarten attendance. METHODS: We collected data from all school beginners in the district of Dingolfing, Bavaria from 2004 to 2007 (n = 4,005) and utilised a retrospective cross-sectional study design to review the information. The children were assessed for motor, cognitive, language and psychosocial impairments using a standardized medical assessment. Point prevalence of impairments of speech, cognition, motor functioning and psychosocial functioning were compared by chi(2)-test for the variable of time spent in kindergarten. RESULTS: We detected a high incidence of impairments, with boys showing higher rates than girls in all the areas assessed. Longer length of time spent in kindergarten was associated with reduced rates of motor, cognitive and psychosocial impairments. There was no clear correlation between length of kindergarten attendance and speech disorders. CONCLUSIONS: Kindergarten attendance may have a positive effect on a number of domains of development including motor, cognitive and psychosocial development, but no significant effect on speech impairments. Implications for public health policies are discussed.

Health service utilization in patients with major depression and co-morbid pain.

AIMS: Patients with depression often have co-morbid pain symptoms. However, rates of service utilization by psychiatric in-patients with co-morbid pain symptoms are unknown. The purpose of this study is to estimate whether patients with major depression and co-morbid pain access medical treatment for their pain as much as their counterparts with psychiatric diagnoses other than major depression. METHODS: A total of 103 patients (62 female; 41 male) were assessed for a diagnosis of major depression applying a psychiatric clinical interview followed by a self-report pain questionnaire, which assessed physical pain in psychiatric patients. RESULTS: Patients with major depression reported higher rates of pain symptoms in the past 6 and 12 months than their counterparts with a psychiatric diagnosis other than major depression. Analysis of variance showed that patients with depression were less likely to attend medical and specialist services for their pain symptoms than their counterparts. On the contrary, depressed patients with pain attended more frequently general in-patient services than non-depressed patients with pain. CONCLUSIONS: Patients with depression suffer high rates of pain symptoms, but are at higher risk of not accessing appropriate services suggesting inadequate service utilization. The results have implications for screening and health care delivery for psychiatric patients with pain.

Psychophysiological mechanisms in panic disorder: a correlative analysis of noradrenaline spillover, neuronal noradrenaline reuptake, power spectral analysis of heart rate variability, and psychological variables.

BACKGROUND: The risk of adverse clinical cardiac events is increased in patients with panic disorder (PD). We evaluated possible mechanistic links between PD and heart disease. We estimated cardiac vagal activity from heart rate variability (HRV) measurements and quantified sympathetic nervous system (SNS) activity using plasma noradrenaline tracer kinetics methodology. METHODS: Thirty-nine people with PD and 39 age- and gender-matched healthy volunteers were studied. In 19 participants with PD, both HRV and plasma noradrenaline kinetics were tested; in 20 with PD and 20 healthy volunteers, HRV measurements only were made, whereas in 19 healthy volunteers, noradrenaline kinetics only was tested. All panic disorder participants completed psychological measures of anxiety sensitivity and state and trait anxiety; healthy volunteers in whom HRV was measured also provided psychological measures. RESULTS: Sympathetic nervous tone in the heart, based on rates of cardiac noradrenaline spillover, was normal in PD. Noradrenaline and adrenaline plasma clearance and plasma tritiated noradrenaline and adrenaline extraction in transit through the heart, all dependent on the noradrenaline transporter (NET), were reduced in PD. Psychometric testing linked inhibition of anger to this deficit in NET functioning. Anxiety sensitivity was specifically associated with impaired cardiac NET. High- and low-frequency heart rate spectral power was unrelated to all plasma noradrenaline kinetics measurements. CONCLUSION: Defective neuronal reuptake of noradrenaline, by augmenting the sympathetic neural signal in the heart, might have a dual effect, sensitizing the heart such as to lead to symptom development (and thus perhaps causing panic disorder) and, second, potentially contributing to adverse cardiac events in established PD.

Effect of omega-3 fatty acids on the lipid profile of patients taking clozapine.

OBJECTIVE: This study aimed to assess the lipid-lowering properties of omega-3 fatty acids (also known as n-3 polyunsaturated fatty acids) in a group of patients taking clozapine. METHOD: Twenty-eight persons suffering from schizophrenia or schizoaffective disorder and currently taking clozapine participated in an open-label single-arm trial. Participants received supplements of 10 g of fish oil (containing 1.8 g of eicosopentaenoic acid and 1.2 g of docosahexaenoic acid) for a period of 28 days. Plasma lipids were measured on days 0 and 28. RESULTS: This study demonstrated high rates of lipid abnormalities in the participants. Participants taking omega-3 fatty acids demonstrated a statistically significant reduction in mean serum triglyceride levels of 22%. There was an associated increase in total cholesterol (6.6%) and low-density lipoprotein cholesterol (22%). Common side-effects included fishy burps or breath, but no serious side-effects or interactions where observed. CONCLUSION: Omega-3 fatty acids may be of value in patients taking clozapine and who have elevated serum triglyceride levels. Limitations of the study, practical implications and directions for future research are discussed.
