Mindfulness Practice Is Associated With Subjective Wellbeing Homeostasis Resilience in People With Crohn's Disease but Not Ulcerative Colitis.

Objectives: People with Crohn's disease and ulcerative colitis (inflammatory bowel disease: IBD), commonly experience high levels of depressive symptoms and stress and low levels of subjective wellbeing (SWB). Mindfulness is increasingly considered an adjuvant IBD treatment. The relationships between depression, disease symptoms and mindfulness have not previously been considered within the theory of SWB homeostasis. This theory states that SWB is normally maintained by a homeostatic system around a setpoint range but can fail when psychological challenges dominate consciousness. This study explored the relationship among SWB and patient-reported psychological and IBD symptoms and investigated whether mindfulness practice is independently associated with SWB homeostatic resilience. Design: This cross-sectional study recruited participants through online IBD support groups. Methods: Participants (n = 739; 62% Crohn's disease) detailed symptoms of depression and stress, patient-reported disease symptoms, and regularity of mindfulness practice. Results: The sample had significantly lower SWB (hedges g = -0.98) than normative data. A logistic regression found mindfulness practice doubled the Crohn's disease participants' odds of reporting SWB within the normal homeostatic range, after controlling for psychological, physical, and demographic variables (OR 2.15, 95% CI: 1.27, 3.66). A one-point increase of patient-reported bowel symptoms reduced the participant's odds of reporting SWB in the normal homeostatic range by about a third (OR 0.66, 95% CI: 0.50, 0.85). However, the influence of mindfulness or disease symptoms on SWB was not observed for people with ulcerative colitis. Conclusion: These findings provide initial evidence for an association between mindfulness and SWB homeostatic resilience in a clinical population.

Low Subjective Wellbeing Is Associated with Psychological Distress in People Living with Inflammatory Bowel Disease.

BACKGROUND: Inflammatory bowel disease (IBD) is a common and debilitating disease of the gastrointestinal tract. Psychological distress is highly comorbid to IBD, especially during periods of active disease. However, a controversy exists on how to best manage its symptoms in the IBD population. AIMS: This study aimed to explore protective and risk factors of psychological distress in IBD. METHODS: A cross-sectional online survey was conducted via social media and online patient forums. Respondents (N = 235) filled out questionnaires on demographics, health characteristics and a range of psychological variables. Measures of pain, disease activity, comorbid functional symptom severity, social support, subjective wellbeing, sleep quality, fatigue, stress, age, BMI and gender were entered into the Classification and Regression Tree Analysis model. RESULTS: Overall, 87 participants (37%) reported distress. Self-reported stress significantly discriminated between cases of probable psychological distress. In those with high stress, patients with and without probable psychological distress were separated by subjective wellbeing. Among patients with low stress, fatigue was the primary discriminator. CONCLUSIONS: Monitoring patients for low subjective wellbeing and high stress in clinical settings could offer an opportunity to engage in early intervention to limit psychological distress development. Monitoring for fatigue in patients who seem otherwise psychologically well could offer preventative benefits.

Efficacy of a Smartphone App Intervention for Reducing Caregiver Stress: Randomized Controlled Trial.

BACKGROUND: Caregivers play a pivotal role in maintaining an economically viable health care system, yet they are characterized by low levels of psychological well-being and consistently report unmet needs for psychological support. Mobile app-based (mobile health [mHealth]) interventions present a novel approach to both reducing stress and improving well-being. OBJECTIVE: This study aims to evaluate the effectiveness of a self-guided mobile app-based psychological intervention for people providing care to family or friends with a physical or mental disability. METHODS: In a randomized, single-blind, controlled trial, 183 caregivers recruited through the web were randomly allocated to either an intervention (n=73) or active control (n=110) condition. The intervention app contained treatment modules combining daily self-monitoring with third-wave (mindfulness-based) cognitive-behavioral therapies, whereas the active control app contained only self-monitoring features. Both programs were completed over a 5-week period. It was hypothesized that intervention app exposure would be associated with decreases in depression, anxiety, and stress, and increases in well-being, self-esteem, optimism, primary and secondary control, and social support. Outcomes were assessed at baseline, postintervention, and 3-4 months postintervention. App quality was also assessed. RESULTS: In total, 25% (18/73) of the intervention participants were lost to follow-up at 3 months, and 30.9% (34/110) of the participants from the wait-list control group dropped out before the postintervention survey. The intervention group experienced reductions in stress (b=-2.07; P=.04) and depressive symptoms (b=-1.36; P=.05) from baseline to postintervention. These changes were further enhanced from postintervention to follow-up, with the intervention group continuing to report lower levels of depression (b=-1.82; P=.03) and higher levels of emotional well-being (b=6.13; P<.001), optimism (b=0.78; P=.007), self-esteem (b=-0.84; P=.005), support from family (b=2.15; P=.001), support from significant others (b=2.66; P<.001), and subjective well-being (b=4.82; P<.001). On average, participants completed 2.5 (SD 1.05) out of 5 treatment modules. The overall quality of the app was also rated highly, with a mean score of 3.94 out of a maximum score of 5 (SD 0.58). CONCLUSIONS: This study demonstrates that mHealth psychological interventions are an effective treatment option for caregivers experiencing high levels of stress. Recommendations for improving mHealth interventions for caregivers include offering flexibility and customization in the treatment design.

A Rasch Analysis of the Personal Well-Being Index in School Children.

The personal well-being index-school children (PWI-SC) is designed as a cross-cultural instrument to measure subjective well-being among high school-aged children. Several published cross-cultural studies have confirmed adequate psychometric performance in terms of reliability, validity, and measurement invariance. This study adds to this literature by applying the Rasch approach to estimate invariant comparison in a cross-cultural context, applied to both Australian and Portuguese high school students. Participants were an age- and gender-matched convenience sample of 1,040 adolescents (520 cases in each group, 51.54% male) who ranged in age from 12 to 18 years (M = 14.25 years, SD = 1.71 years). It is found that both Portuguese and Australian data fit the Rasch measurement model, with excellent levels of reliability at a country level. However, when all of the data were combined, a slight misfit was found. This was resolved by removing some issues with item thresholds in standard of living among the Australian data and splitting the data by country on health. This allowed both Australian and Portuguese cases to differ on the health item. We conclude that the PWI-SC is unidimensional, with some evidence of mild, but acceptable local dependency. This study further supports the cross-cultural validity of the PWI-SC and the use of this measure in the Australian and Portuguese context but also indicates a potential direction that development of the PWI-SC might proceed.

Using dynamic factor analysis to provide insights into data reliability in experience sampling studies.

The past 2 decades have seen increasing use of experience sampling methods (ESMs) to gain insights into the daily experience of affective states (e.g., its variability, as well as antecedents and consequences of temporary shifts in affect). Much less attention has been given to methodological challenges, such as how to ensure reliability of test scores obtained using ESM. The present study demonstrates the use of dynamic factor analysis (DFA) to quantify reliability of test scores in ESM contexts, evaluates the potential impact of unreliable test scores, and seeks to identify characteristics of individuals that may account for their unreliable test scores. One hundred twenty-seven participants completed baseline measures (demographics and personality traits), followed by a 7-day ESM phase in which positive and negative state affect were measured up to 6 times per day. Analyses showed that although at the sample level, scores on these affect measures exhibited adequate levels of reliability, up to one third of participants failed to meet conventional standards of reliability. Where these low reliability estimates were not significantly associated with personality factors, they could-in some cases-be explained by model misspecification where a meaningful alternative structure was available. Despite these potential differences in factor structure across participants, subsequent modeling with and without these "unreliable" cases showed similar substantive results. Hence, the present findings suggest typical analyses based on ESM data may be robust to individual differences in data structure and/or quality. Ways to augment the DFA approach to better understand unreliable cases are discussed. (PsycINFO Database Record

Understanding Quality of Life in Medicine: A New Approach.

This article introduces the subjective side of quality of life as it has evolved within the discipline of psychology. Subjective well-being is also of special interest within medicine due to its links to pathology and the fact that it is managed by a homeostatic system. This form of management offers an explanation for the unusual properties of subjective well-being, including its normal positivity, stability, and nonlinear relationship to objective variables, such as physical health. Central to understanding is the proposition that subjective well-being mainly consists of a specific form of trait mood. This homeostatically protected mood has a genetic set point and it is the experience of this set-point mood that homeostasis is defending. The resources required to maintain normal homeostatic control are described. If these resources are inadequate to protect the experience of set-point mood, mood positivity falls, and there is a high probability of depression. In this article, the process of homeostasis is shown to assist understanding of intervention effectiveness within both psychology and medicine. This concerns matters of resilience, the nonlinear relationship between levels of subjective well-being, and the strength of challenging agents, and the important understanding that interventions designed to raise subjective well-being are critically dependent on its level at baseline. Key teaching points: The physiological process of homeostasis has a parallel in psychology in the homeostatic management of subjective well-being. Subjective well-being is a more globally informative construct than health-related quality of life. How people feel about themselves and their lives cannot be simply predicted through measures of health. When subjective well-being homeostasis is defeated, there is a high probability of depression.

THE HAPPINESS AND SUBJECTIVE WELL-BEING OF PEOPLE ON HAEMODIALYSIS.

BACKGROUND: Happiness is a construct that has been gaining more prominence in both social and health research. The measure of happiness, subjective well-being, has not been rigorously explored in the end-stage kidney disease (ESKD) population. OBJECTIVES: To measure the subjective well-being of people with ESKD on haemodialysis and to compare their subjective well-being with a general population cohort. DESIGN: A cross-sectional design measuring the subjective well-being of an Australian haemodialysis cohort compared with a non-dialysis age-matched cohort. PARTICIPANTS: The haemodialysis cohort (N = 172), recruited from eight dialysis centres, had a mean age of 64.04 years (SD = 14.82) and included 104 males (60.5%) and 66 (38.4%) females. The non-dialysis cohort (N = 200), randomly extracted from the 2012 Australian Unity Wellbeing Index, had a mean age of 63.97 (SD = 14.68) and included 101 males (50.5%) and 99 females (49.5%). MEASUREMENT: Subjective well-being was measured using the Personal Wellbeing Index. This seven-item measure rates satisfaction with life in seven domains: standard of living, health, achievements in life, relationships, safety, community and future security. RESULTS: The haemodialysis cohort reported lower general life satisfaction, life achievements, relationship and personal safety compared to the general population. There were no differences between the two groups for health, community and future security. Standard of living and satisfaction with life achievements carried higher importance in subjective well-being compared with health satisfaction CONCLUSION: Subjective well-being can be an important indicator of people's life quality to be considered by clinicians and nephrology researchers in future studies.

The dyadic interaction of relationships and disability type on informal carer subjective well-being.

PURPOSE: Care-related factors have frequently been associated with elevated levels of distress and diminished subjective well-being. However, these variables have traditionally been considered independently. The objectives of this study were to explore the subjective well-being of informal carers in Australia and to specifically examine the effect of the dyadic interaction between the caring relationship and type of disability on the subjective well-being of informal carers. METHODS: Informal carers (n = 4,096) completed the Personal Wellbeing Index (PWI) and Depression and Stress Scales. Analysis of covariance was used to compare the subjective well-being of carers to the general population while controlling for socio-demographic factors. To examine the dyadic relationship, a multivariate analysis of covariance was employed. RESULTS: After socio-demographic variables were controlled, informal carers reported significantly lower PWI scores compared to the general population. The results of the multivariate analysis of covariance revealed a significant interaction between the caring relationship and the type of disability being managed on subjective well-being. No differences were found for symptoms of depression and stress. CONCLUSIONS: The findings of this study imply that the detrimental effect of caring on subjective well-being is magnified for carers who support a child with a mental illness or multiple types of disabilities. These carers displayed the lowest levels of subjective well-being, highlighting the dyadic effects of care-related variables. Consideration of these factors is essential to target effective intervention programs for those most at risk of diminished well-being.

Clinical outcomes associated with screening and referral for depression in an acute cardiac ward.

AIM: The aim of this paper is to describe the implementation of a depression screening and referral tool in two cardiac wards of a major metropolitan public hospital. The tool consisted of two sections: (1) screening for depression risk (Cardiac Depression Scale-5) and (2) consequential referral actions. BACKGROUND: Prior research has shown that depression in patients with heart disease is associated with significantly impaired quality of life, decreased medication adherence, increased morbidity and increased use of healthcare services. DESIGN: A prospective in-patient study design. METHOD: A consecutive sample of 202 patients admitted to either the cardiac medical (n = 145) or surgical (n = 57) wards of a major Melbourne metropolitan hospital were recruited into the study over an 18-week period. RESULTS: Just over half (54%) of the patients were identified as 'at risk' of depression. Of these, 19% were assessed as moderate risk and 35% high risk. Of those patients, 91% had the risk score documented in their medical history, 90% had engaged in discussions with clinicians regarding their risk score, 85% had their risk score communicated formally to the medical team and 25% were formally referred for appropriate follow-up - significantly more than prior to implementation of the screening and referral tool. CONCLUSIONS: By providing a formalised mechanism for detecting depression, documented screening and referral rates improved for those with comorbid depression and heart disease affording an opportunity for early intervention. These findings support a move towards integrated approaches to screening of depression to become standard practice in the acute cardiac setting. RELEVANCE TO CLINICAL PRACTICE: Such mechanisms also have the potential to initiate the development of new models of care that acknowledge the complexity of comorbid depression and heart disease and provide pathways from speciality to primary care which integrate the physical and psychosocial domains inclusive of screening, referral, systematic monitoring and streamlined behavioural and physical care.

Meehl's "crud" factor, subjective wellbeing, and religiosity: a critique'.

Researchers in the area of subjective wellbeing are now building on a body of research that spans more than three decades and includes many thousands of articles. It is time to move from exploratory studies to those based on accumulated psychometric understanding and theory. Two aspects of the article by Abdel-Khalek (2011) warrant attention from this perspective: the choice of scale and the issue of shared variance.

Primary and secondary control over eating behaviors.

The relationships between subjective control, body image, and eating behaviors were examined within the framework of the Optimization in Primary and Secondary Control model (OPS model; Heckhausen, 1999). This model characterizes control as an adaptive and strategic process in which the target of control includes internal as well as external states, and in which the purpose is either to facilitate goal pursuit by engaging with the goal or managing the consequences of goal failure by disengaging from the goal. A convenience sample of 180 Australian women (age: M=26.49, SD=5.03) completed the Optimization of Primary and Secondary Control Scale (OPS scale Heckhausen, 1999), as well as measures of attitudinal and behavioral factors comprising Stice's (1994) dual-pathway model of bulimia. A series of path analyses revealed that the control strategies involved in goal engagement are directly associated with increased dietary restraint and purging, whereas the control strategies involved in goal disengagement are indirectly associated with these factors, and with negative affect, by way of reduced body dissatisfaction and reduced frequency of appearance comparisons. These results suggest that goal engagement strategies, which are typically adaptive in other contexts, are associated with potentially hazardous attitudes and behaviors in the context of the body. The results also suggest that an ability to disengage from body weight goals is associated with a reduced likelihood of developing disordered eating.

Fluency disorders and life quality: subjective wellbeing vs. health-related quality of life.

UNLABELLED: It seems intuitive that people with a fluency disorder, such as stuttering, must experience a low life quality. Yet this is not necessarily so. Whether measured life quality is lower depends on several factors, the most important of these being methodological. This is because the disciplines of medicine and the social sciences utilize quite different technologies to measure the construct. Within medicine, health-related quality of life (HRQOL) is measured through constellations of perceived symptoms. Thus, if the symptoms chosen to represent HRQOL match the pathological characteristics of the fluency disorder, the relationship is self-fulfilling. Psychology, on the other hand, uses subjective wellbeing to represent life quality. Here, the relationship between symptoms and perceived life quality is much less certain. It is proposed that this partial disconnection is due to the presence of a homeostatic system which manages subjective wellbeing in an attempt to keep it positive. The paper that follows examines the construct of life quality from both disciplinary perspectives, and then reports on the findings from each discipline in relation to fluency disorders. It is concluded there is no necessary link between fluency disorders and life quality provided subjective wellbeing is used as the indicator variable. EDUCATIONAL OBJECTIVES: The reader will be able to describe: (i) contemporary issues in quality of life measurement; (ii) the relationship between fluency disorders and life quality; (iii) the conceptual limitations of health-related quality of life.

Recovering from an acute cardiac event--the relationship between depression and life satisfaction.

AIMS: This study sought to measure the rates and trajectory of depression over six months following admission for an acute cardiac event and describe the relationship between depression and life satisfaction. BACKGROUND: Co-morbid depression has an impact on cardiac mortality and is associated with the significant impairment of quality of life and well-being, impairments in psychosocial function, decreased medication adherence and increased morbidity. DESIGN: This was a descriptive, correlational study. METHOD: The study was undertaken at a large public hospital in Melbourne. Participants were asked to complete a survey containing the cardiac depression scale (CDS) and the Personal Well-being Index. RESULTS: This study mapped the course of depression over six months of a cohort of patients admitted for an acute cardiac event. Significant levels of depressive symptoms were found, at a level consistent with the literature. A significant correlation between depressive symptoms as measured by the CDS and the Personal Well-being Index was found. CONCLUSIONS: Depression remains a significant problem following admission for an acute coronary event. The Personal Well-being Index may be a simple, effective and non-confrontational initial screening tool for those at risk of depressive symptoms in this population. RELEVANCE TO CLINICAL PRACTICE: Despite the known impact of depression on coronary heart disease (CHD), there is limited research describing its trajectory. This study makes a compelling case for the systematic screening for depression in patients with CHD and the importance of the nursing role in identifying at risk individuals.

The SARS (Severe Acute Respiratory Syndrome) pandemic in Hong Kong: effects on the subjective wellbeing of elderly and younger people.

OBJECTIVES: This study examined the impact of the Severe Acute Respiratory Syndrome (SARS) outbreak in Hong Kong in 2003, on the subjective wellbeing (SWB) of elderly people and a younger comparative sample. The Personal Wellbeing Index (PWI), a contemporary instrument employed to measure SWB, was also examined for its psychometric performance to substantiate its use. METHOD: A total of 302 older adults (age 65 + years) and 158 younger adults (age 35-46 years) were recruited from different districts. Data were collected by individual face-to-face interviews. RESULT: While elderly people living in severely infected districts showed significantly lower levels of SWB, these levels and those of the younger sample were found to remain within the normative range. A major mitigating factor was an increased sense of community-connectedness. Other characteristics linked to low wellbeing levels included chronic illness, female gender, low education and unemployment. The living districts, characterized by varying extents of infection, had stronger associations with SWB than participants' age. The PWI demonstrated good psychometric performance and also more robustness with elderly people, including its sensitivity to the sense of population threat. CONCLUSION: Psychological resilience was identified among both the elderly and younger age-groups in Hong Kong during the SARS pandemic. The PWI is verified as a suitable instrument for SWB measurements.

Self-perceived quality of life of children and adolescents with physical disabilities in Hong Kong.

Although illnesses and diseases are thought to adversely affect quality of life (QoL), whether children who have physical disabilities (PD) from a young age adapt to the effect of developmental disabilities has rarely been investigated. This study attempted to assess the subjective wellbeing, and examine the correlation between objective and subjective QoL, of children with PD. Using a self-reported non-disease-specific questionnaire, the QoL of 72 young persons (13.5+/-2.0 years) with PD was contrasted with those who do not have disabilities (n = 510; age-matched). MANOVA analyses revealed that the PD group had lower objective QoL score (63.0+/-7.4 vs. 66.8+/-5.7, p < 0.001) but the two groups were not significantly different in subjective QoL score (70.9+/-11.4 vs. 69.6+/-13.6, p = 0.466). No correlation was found between objective and subjective QoL in the PD group (r ranged from 0.06 to 0.19), while weak to medium correlations (r ranged from 0.03 to 0.41) were observed for the controls. The apparent detachment of subjective feeling and objective circumstances in the PD group may reflect adjustment to developmental disabilities.

HRQOL and subjective well-being: noncomplementary forms of outcome measurement.

This review considers some of the broad principles that concern quality of life assessment. These are discussed in relation to health-related quality of life (HRQOL) and the measurement of subjective well-being. It is argued that there are serious logical and methodological issues concerning HRQOL measurement, to the extent that the instruments may not be regarded as valid measures of life quality as this term is generally understood. It is recommended that HRQOL measurement be abandoned in favor of three separate forms of measurement as medical symptoms, subjective well-being and specific dimensions of psychological ill-being.

Measuring health in a vacuum: examining the disability weight of the DALY.

The Disability Adjusted Life Year (DALY) is a widely used summary measure of population health combining years of life lost due to mortality and years of healthy life lost due to disability. A feature of the DALY is that, in the assessment of morbidity, each health condition is associated with a disability weight. The disability weight lies on a scale between 0 (indicating the health condition is equivalent to full health) and 1 (indicating the health condition is equivalent to death). The disability weight associated with each health condition is currently fixed across all social, cultural and environmental contexts. Thus blindness in the United Kingdom has the same disability weight as blindness in Niger in spite of structural interventions in the UK that make the disability less severe than in Niger. Although the fixed disability weight is defended on grounds that it supports a strongly egalitarian flavour in the DALY, we argue that the lack of consideration of realistic contexts results in a measure that will underestimate the burden associated with morbidity in disadvantaged populations and overestimate the burden in advantaged populations. There is, consequently, a loss of information on possible non-clinical points of intervention. Disaggregated estimates of the burden of disease such as those in the World Health Report 2000 should be interpreted with caution.

The management of subjective quality of life by short-stay hospital patients: an exploratory study.

BACKGROUND: This study tested the homeostatic model of subjective quality of life in a group of 47 short stay patients as they progressed through the stages of hospitalization for surgery. METHOD: Participants completed a questionnaire measuring subjective quality of life, positive and negative affect, self-esteem, optimism and cognitive flexibility, the day prior to admission (T1), two days post-operation (T2) and one week after discharge (T3). Neuroticism and Extroversion were measured at Time 1. RESULTS: All variables remained stable across the three times, apart from positive affect, which dropped significantly post-operation but returned to its previous level post discharge. CONCLUSION: Although the homeostatic model of subjective quality of life was supported at Time 1, the analyses raise doubts about the stability of personality. This finding is consistent with recent discussions of personality.
