Intervention efficacy among 'At Risk' adolescents: a test of subjective wellbeing homeostasis theory

 This study tests a number of theoretical predictions based on subjective wellbeing (SWB) Homeostasis Theory. This theory proposes that SWB is actively maintained and defended within a narrow, positive range of values around a 'set-point' for each person. Due to homeostatic control, it is predicted to be very difficult to substantially increase SWB in samples operating normally within their set-point-range. However, under conditions of homeostatic defeat, where SWB is lower than normal, successful interventions should be accompanied by a substantial increase as each person's SWB returns to lie within its normal range of values. This study tests these propositions using a sample of 4,243 participants in an Australian Federal Government Program for 'at-risk' adolescents. SWB was measured using the Personal Wellbeing Index and results are converted to a metric ranging from 0 to 100 points. The sample was divided into three sub-groups as 0-50, 51-69, and 70+ points. The theoretical prediction was confirmed. The largest post-intervention increase in SWB was in the 0-50 group and lowest in the 70+ group. However, a small increase in SWB was observed in the normal group, which was significant due to the large sample size. The implications of these findings for governments, schools and policy makers are discussed.

Risk homeostasis theory in simulated environments

This thesis has two aims. First, it sets out to develop an alternative methodology for the investigation of risk homeostasis theory (RHT). It is argued that the current methodologies of the pseudo-experimental design and post hoc analysis of road-traffic accident data both have their limitations, and that the newer 'game' type simulation exercises are also, but for different reasons, incapable of testing RHT predictions. The alternative methodology described here is based on the simulation of physical risk with intrinsic reward rather than a 'points pay-off'. The second aim of the thesis is to examine a number of predictions made by RHT through the use of this alternative methodology. Since the pseudo-experimental design and post hoc analysis of road-traffic data are both ill-suited to the investigation of that part of RHT which deals with the role of utility in determining risk-taking behaviour in response to a change in environmental risk, and since the concept of utility is critical to RHT, the methodology reported here is applied to the specific investigation of utility. Attention too is given to the question of which behavioural pathways carry the homeostasis effect, and whether those pathways are 'local' to the nature of the change in environmental risk. It is suggested that investigating RHT through this new methodology holds a number of advantages and should be developed further in an attempt to answer the RHT question. It is suggested too that the methodology allows RHT to be seen in a psychological context, rather than the statistical context that has so far characterised its investigation. The experimental findings reported here are in support of hypotheses derived from RHT and would therefore seem to argue for the importance of the individual and collective target level of risk, as opposed to the level of environmental risk, as the major determinant of accident loss.

Personal resilience in times of crisis : the implications of SWB homeostasis and set-points

Our companion paper (Cummins et al. in J Happiness Stud, 2013) describes the statistical process used to demonstrate set-points and set-point-ranges for subjective wellbeing. The implications of set-points and homeostasis are now considered in the context of resilience. This discussion leads with a brief overview of resilience definitions and is followed by a description of subjective wellbeing (SWB) homeostasis. This addresses, in particular, the issue of SWB malleability under homeostatic control. The link between resources and resilience is then considered, in terms of predictions made by homeostasis theory. Finally, discussion focuses on the implications of such understanding for future directions in SWB research. It is concluded that an understanding of set-points and homeostasis allows new insights into the resilience construct.

An investigation into the cross-cultural equivalence of the personal wellbeing index

The Personal Wellbeing Index (PWI) is being developed for the cross-cultural measurement of subjective wellbeing (SWB). This paper reports the findings of its utility with the Hong Kong Chinese and Australian populations. An item on affect, ‘satisfaction with own happiness’ was also investigated to determine whether it should be added to the index. Three-hundred and sixty participants (180 per country), with equal representation from groups aged 18–35, 35–64 and 65 years and above, were recruited from each country. The PWI demonstrated good psychometric performance in terms of its reliability, validity and sensitivity, which are comparable in both countries. The item ‘satisfaction with own happiness’ was found to contribute significantly to the scale’s psychometric performance in Australia but not in Hong Kong. Cultural differences in the perception of the concepts ‘satisfaction’ and ‘happiness’ were suggested as an explanation for this finding. The PWI data are also consistent with homeostasis theory, which proposes that each person’s SWB level is maintained within a limited positive range. For the Australian population, their mean SWB level fell within the established Western range of 70–80, on a scale from 0 to 100. The Hong Kong population, however, fell below this range. Cultural response bias was identified as a plausible explanation for the differences between the Hong Kong and Australian samples.

Measuring wellbeing in developing countries: the case of Algeria

The International Wellbeing Index (IWI) has been developed as a complementary measure to already well-known economic measures, and as a tool for cross-cultural comparisons. It comprises two subscales: the Personal Wellbeing Index (PWI) and the National Wellbeing Index (NWI). The aims of this paper are two-fold. Firstly, to test the psychometric characteristics of the IWI. Secondly, to study how people of Algeria, a third world country that is yet suffering from a harsch economical and social situation, respond to questions dealing with their own lives and life in their country in general, compared to samples from more developed countries where wellbeing was previously measured. The IWI items were presented to individuals either in a questionnaire form to be self-rated or in interview sessions. The total of 1417 answers were analysed. As was expected, a very low satisfaction on both scales was found, compared to the results that were reported in countries, such as Australia or Hong Kong. Comparisons on the demographic characteristics basis show that women are significantly more satisfied than men with their personal lives, though no differences were found with regard to NWI. Eldest and youngest age groups rated the PWI significantly higher than other age groups. Education groups comparisons showed higher ratings on both subscales in favour of groups with no education and those with university levels. Marginal statistically significant differences were found with regard to the PWI in favour of the higher earning group, but no differences in the NWI. No statistically significant results were found as far as marital status, number of children, and income are concerned. The results add to the evidence of the usefulness of the scale to predict satisfaction of people with their own lives and life in their country. Its psychometric performance was proved to be very high in terms of validity, reliability and sensitivity. The results were interpreted on the light of the Homeostasis Theory and the particular situation of the Algerian society.

Subjective well-being maintenance

This thesis research examined the relationship between SWB and depression in the context of homeostasis theory. Results provide support for homeostasis as the SWB maintenance mechanism and strong support for conceptualising depression as a loss of SWB. Remarkable, results also indicate that some SWB measures outperform depression inventories in detecting depression. The portfolio uses attachment theory as a conceptual framework for understanding the contribution of attachment relationships to the development of borderline and antisocial personality pathology in children and adolescents. Four case studies are presented in illustration.

Quality of life in Australia

This chapter describes some aspects of life quality in Australia. The data for the initial overview have come from various sources. Following this general introduction, the chapter concentrates on two areas of Australian life that are key to subjective wellbeing. Using the combined data base from 24 surveys using the Australian Unity Wellbeing Index, we identified the happiest and the saddest groups in Australia as defined by their demographic profile. The highest wellbeing groups comprise people who have both a partner and a decent level of wealth. The lowest wellbeing groups are people with no partner, who have a low income and who are unemployed. The chapter then concentrates on the two common, defining elements of the highest and lowest groups as money and relationships. The results are interpreted in terms of data norms, homeostasis theory and possible causal agents. It is concluded that the results generally conform to the predictions of homeostasis and offer signposts as to the kinds of structural changes that influence population wellbeing.

Life quality and wealth : a qualitative and quantitative comparison of affluent and poor people

It is well-documented that auent people, on average, have higher subjective wellbeing (SWB) than do poor people. is phenomenon has been explained using SWB homeostasis theory. However, a more precise understanding of the dierences in personal experience that lead to homeostatic failure remains to be documented. We sought such understanding through qualitative interviews and a quantitative examination of SWB domains. Twenty auent people and 20 people dependent on social welfare completed an interview and the Personal Wellbeing Index. As expected, the two groups diered signicantly in SWB. Moreover, the poor group reported a preponderance of negative life experiences while the auent group concentrated on the positive events in their lives. Most telling was the nding that both the qualitative and quantitative methods identied the area of ‘relationships’ as representing the greatest degree of divergence between the two groups. is life domain is especially relevant in the maintenance of normative levels of SWB.

The Psychometric Equivalence of the Personal Wellbeing Index for Normally Functioning and Homeostatically Defeated Australian Adults

Understanding subjective wellbeing (SWB) at the population level has major implications for governments and policy makers concerned with enhancing the life quality of citizens. The Personal Wellbeing Index (PWI) is a measure of SWB with theoretical and empirical credentials. Homeostasis theory offers an explanation for the nature of SWB data, including the distribution of scores, maintenance and change over time. According to this theory, under normal conditions, the dominant constituent of SWB is Homeostatically Protected Mood (HPMood), which is held within a genetically determined range of values around a set-point. However, in extreme circumstances (e.g., financial hardship, chronic illness), HPMood may dissociate from SWB, as cognitive/emotional reactions to the cause of homeostatic challenge assume control over SWB. This study investigates two groups as people scoring in the positive range for SWB and people who are likely to be experiencing homeostatic defeat/challenge. We test whether the reduced influence of HPMood on SWB due to homeostatic defeat has implications for the validity of SWB measurement. Participants were 45,192 adults (52 % female), with a mean age of 48.88 years (SD = 17.35 years), who participated in the first 23 surveys of the Australian Unity Wellbeing Index over the years 2001–2010. Multiple regression analysis, multiple group confirmatory factor analysis, and Rasch modelling techniques were used to evaluate the psychometric performance of the PWI across the two groups. Results show that while the PWI functioned as intended for the normal group, SWB in the challenged group was lower across all PWI domains, more variable, and the domain scores lacked the strength of inter-correlation observed in the normal, comparison group. These changes are consistent with predictions based on homeostasis theory and one major implication of the findings is that SWB measures may not function equivalently across the entire spectrum of possible domain satisfaction scores.

Rebound or resignation: developing a predictive model of return to subjective wellbeing set-point

Though subjective wellbeing (SWB) is generally stable and consistent over time, it can fall below its set-point in response to adverse life events. However, deviations from set-point levels are usually only temporary, as homeostatic processes operate to return SWB to its normal state. Given that income and close interpersonal relationships have been proposed as powerful external resources that are coincident with higher SWB, access to these resources may be an important predictor of whether or not a person is likely to recover their SWB following a departure from their set-point. Under the guiding framework of SWB Homeostasis Theory, this study considers whether access to a higher income and a committed partner can predict whether people who score lower than normal for SWB at baseline will return to normal set-point levels of SWB (rebound) or remain below the normal range (resigned) at follow-up. Participants were 733 people (53.3 % female) from the Australian Unity Longitudinal Wellbeing Study who ranged in age from 20 to 92 years (M = 59.65 years; SD = 13.15). Logistic regression analyses revealed that participants’ demographic characteristics were poor predictors of whether they rebounded or resigned. Consistent with homeostasis theory, the extent of departure from the proposed normal SWB set-point at baseline was significantly associated with rebound or resignation at time 2. These findings have implications for the way that SWB measures can be used in professional practice to identify people who are particularly vulnerable to depression and to guide the provision of appropriate and effective therapeutic interventions.

Moving from the quality of life concept to a theory

BACKGROUND: The Special Interest Quality of Life Group has updated its set of statements defining the quality of life (QOL) construct to reflect emerging areas of agreement and the framework for understanding better the QOL construct.
METHOD: This article examines the major areas currently under discussion involving the objective-subjective dichotomy, needs, and core domains.
RESULTS: It is concluded that while the new statements constitute a significant advance, further progress requires testable theory. In order to facilitate such future research, a conceptual model is proposed that distinguishes causal and indicator variables within the framework of a homeostatic management system.
CONCLUSION: Several lines of empirical investigation are suggested to test this and similar theoretical models with a view to taking our conceptualization of QOL to the next level.

Comparison theory in economic psychology regarding the easterlin paradox and decreasing marginal utility : a critique

This paper challenges the assumption within Economics that the relationship between money and subjective wellbeing is determined by processes of cognitive comparison. An alternative explanation for such well known phenomena as the Easterlin Paradox and Decreasing Marginal Utility are provided through a consideration of affect. The theoretical basis for such explanations relies on theory from Psychology usually overlooked by Economists, such as affect heuristics and Subjective Wellbeing Homeostasis. The presented evidence for this alternative source of explanation melds psychological theory with empirical data. It is concluded that affective processes offer a coherent alternative explanation for the phenomena under discussion.

Subjective wellbeing homeostasis

The idea of homeostasis has a long history in physiology, describing a process that maintains important variables within a narrow range of values. Core body temperature is a well-known example, where a variation of just a few degrees higher or lower than normal signals pathology. Within psychology, homeostatic systems are less commonly understood, but one that has received attention is the systematic management of the positive feelings about our self, known as subjective wellbeing. This article describes homeostasis in the context of human resilience and discusses the implications for both theory and psychological practice.
