Despite increasing research interest in the subjective wellbeing (SWB) of Indigenous Australians, SWB measures used in these studies have not been validated for use in this population. Until the measurement equivalence of scales used in this population are demonstrated, inferences regarding potential differences in SWB across Indigenous and non-Indigenous groups cannot be validly inferred. To rectify this, the present study examines the psychometric equivalence of the Personal Wellbeing Index—School Children (PWI-SC) for use among samples of Indigenous and non-Indigenous Australian adolescents using multiple-group confirmatory factor analysis. The Indigenous sample comprised 1,378 adolescents enrolled in the Australian Federal Government’s Youth Connections Program. A sample of 6,401 non-Indigenous adolescents also enrolled in the Youth Connections Program represented a second comparative group. Finally, the third comparative group comprised a convenience sample of 983 Victorian high-school students. The results demonstrated strict factorial invariance between all three adolescent groups, suggesting that the PWI-SC measures the same underlying construct in each sample. These findings support quantitative comparisons between Indigenous and non-Indigenous SWB data as valid. The implications of this research are discussed. 相似文献

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. 相似文献

Objective
Resilience is an important and underdeveloped area of research, and there are few studies that describe levels of resilience among youth samples. A major aim of this research is to explore the utility of an adapted form of the 10‐item Connor Davidson Resilience Scale and to clarify the association between this construct and a robust measure of subjective wellbeing.Method
A representative sample of 1000 Victorians aged 16–25 years participated in a telephone interview comprising the modified 10‐item Connor Davidson Resilience Scale and the Personal Wellbeing Index.Results
The modified 10‐item Connor Davidson Resilience Scale demonstrated adequate inter‐item reliability and factored as intended. A moderate, positive correlation was found between the modified 10‐item Connor Davidson Resilience Scale and the Personal Wellbeing Index. Significance testing revealed group differences for gender, age, and annual household income. The results are also used to establish theoretical “normal” ranges for resilience in Victoria's youth population.Conclusion
The results from this study support the modified 10‐item Connor Davidson Resilience Scale as a valid and reliable measure of young people's resilience using traditional psychometric tests. Moreover, this is the first study to describe the levels of resilience among Victorian youths and to evaluate these data alongside a robust measure of subjective wellbeing. The implications of the findings for government policy and service delivery are discussed. 相似文献6.

The practice of comparing nations on subjective wellbeing (SWB) is becoming commonplace, with many countries ranked by economists and social scientists alike according to average levels of SWB based on survey responses. Such large, multi-national population surveys have the potential to generate insights into the causes and correlates of SWB within different cultural groups, as well as inform policy regarding how to improve the wellbeing of citizens. At the heart of these large-scale research endeavors are SWB measures that function equivalently between the various participating cultural groups. For this reason, it is concerning that their remains a paucity of research that supports measurement equivalence for many SWB instruments commonly employed. Thus, it remains unclear whether variations in SWB across cultures reflect true differences, or whether these differences reflect measurement biases (e.g., response bias inherent within a particular cultural group). The aim of this study was to examine the psychometric equivalence of the Personal Wellbeing Index–School Children (PWI-SC) in convenience samples of Australian and Portuguese adolescents using multiple-group confirmatory factor analysis. Participants comprising the Australian sample were 1104 Victorian high-school students aged between 12 and 19 years (M?=?14.42, SD?=?1.63). Participants comprising the Portuguese sample were 573 high-school students living in Portugal aged between 12 and 18 years (M?=?14.32, SD?=?1.72). The results demonstrated strict factorial invariance between both versions of the PWI-SC, suggesting that this scale measures the same underlying construct in both samples. Moreover, these findings provide preliminary support for quantitative comparisons between Australian and Portuguese adolescents on the SWB variable as valid. 相似文献

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. 相似文献

Research is scarce concerning the validity of subjective wellbeing measures for children aged 12 years and less. There are even fewer subjective wellbeing data for children with complex backgrounds and personal circumstances and those experiencing socio-demographic disadvantage. This study compares the psychometric properties of the child and adult versions of the Personal Wellbeing Index. Participants were 1761 ‘at-risk’ children aged 10–12 years, and 2000 geographically representative Australian adults. While there was sufficient fit with a one-factor structure, the reliability estimates were lower in the child sample and the incidence of response bias was significantly higher. Collectively, these findings suggest caution in the use of subjective wellbeing measures with children. 相似文献

Researchers generally agree that Subjective Wellbeing (SWB) comprises both cognitive and affective components. However, the
proportioning of their contributions, and the relationship between these constructs and personality, remain equivocal. This
study investigated the relationship between these constructs, representing affect by Homeostatically Protected Mood (HPMood).
Using a sample of 205 Victorian high-school students aged between 13 and 20 years, structural equation modeling determined
that an HPMood-driven model of SWB was better fitting than either a personality-driven model of SWB or a cognition-driven
model of SWB, explaining 80% of variance. These results support HPMood as the major component of SWB. They also reinforce
the proposition that HPMood may be the driving force behind individual SWB set-points and the variable that SWB homeostasis
seeks to defend. 相似文献
