The health-related quality of life of obese persons seeking or not seeking surgical or non-surgical treatment:A meta-analysis

Background: A meta-analysis examined differences in health-related quality of life (HRQoL) between seekers of surgical and non-surgical treatment, and non-treatment seekers, over and above differences that are explained by weight, age, and gender. Methods: Our literature search focused on the 'Impact of Weight on Quality of Life-Lite' (IWQOL-Lite) and the 'Short Form-36' (SF-36) questionnaires. Included were studies published between 1980 and April 2006 providing (pre-treatment) descriptive statistics of adult overweight or (morbid) obese persons. Excluded were elderly and ill patient groups. Results: Fifty-four articles, with a total number of nearly 100.000 participants, met the inclusion criteria. Persons seeking surgical treatment demonstrated the most severely reduced HRQoL. IWQOL-Lite scores showed larger differences between populations than SF-36 scores. After adjustment for weight, the population differences on the IWQOL disappeared. In contrast, the differences on the SF-36 between the surgical treatment seeking population and the other populations were maintained after adjustment for weight. Conclusion: The IWQOL-Lite questionnaire predominantly reflects weight-related HRQoL, whereas the SF-36 mostly reflects generic HRQoL that is determined by both weight and other factors. Our meta-analysis provides reference values that are useful when explicating or evaluating obesity-specific (IWQOL-Lite) or generic (SF-36) HRQoL, weight, and demographic characteristics of obese persons seeking or not seeking surgical or non-surgical treatment

Employment insecurity and life satisfaction: The moderating influence of labour market policies across Europe

This article tests whether the link between employment insecurity and life satisfaction is moderated by the generosity of labour market policies across Europe. Employment insecurity provokes anxieties about (a) the difficulties of finding a new job and (b) alternative sources of non-work income. These components can be related to active and passive labour market policies, respectively. Generous policy support is thus expected to buffer the negative consequences of employment insecurity by lowering the perceived difficulty of finding a similar job or providing income maintenance during unemployment. Based on data for 22 countries from the 2010 European Social Survey, initial support for this hypothesis is found. Perceived employment insecurity is negatively associated with life satisfaction but the strength of the relationship is inversely related to the generosity of labour market policies. Employment insecurity, in other words, is more harmful in countries where labour market policies are less generous

Institutions versus market forces: Explaining the employment insecurity of European individuals during (the beginning of) the financial crisis

In reaction to the recent financial crisis, the European Commission re-stated its view that the balance between flexibility and security is the key to success for the future of the European social economy, as well as its belief in the power of institutional arrangements it deems necessary for this balance. However, do powerful institutions actually counter market forces where flexicurity is concerned? In this paper we address this question by analysing the impact of institutional configurations and market factors on perceived employment insecurity among workers in Europe. We use the 4th wave of the European Social Survey for 2008/2009, which covers 22 countries, and implement a multi-level approach where contextual effects are taken into account and individuals are considered to be embedded within a country. We find that policies that secure one’s income and employability skills, such as passive and active labour market policies, are more important for providing employment security for individuals than institutions that secure one’s current job, such as employment protection. Of the economic and labour market factors, general market conditions (measured as employment rate average) and the strength of the financial crisis (measured as gross domestic product growth rate from 2008 to 2009) are both similarly influential in explaining cross-national variance in the employment insecurity perception of individuals. More generally, and most interestingly, we find that institutional factors lose their significance when market factors are taken into account. Thus, it seems that differences in economic and labour market conditions between countries better explain why workers feel insecure about their employment, than the differences in employment and income policies. Although this result could be influenced by the time period under investigation, which is characterized by a financial crisis, results from previous studies using data from different periods suggest that it is not period-specific

Investigating the role of two types of understanding in relationship well-being: Understanding is more important than knowledge

Understanding is at the heart of intimate relationships. It is unclear, however, whether understanding-partners' subjective feeling that they understand each other-or knowledge-partners' accurate knowledge of each other-is more important for relationship well-being. The present article pits these two types of understanding against each other and investigates their effects on relationship well-being. In a prospective study among 199 newlywed couples, partners' self-reported and perceived understanding and their knowledge in different domains were assessed. Understanding was independent of knowledge. Self-reported and perceived understanding predicted relationship well-being but neither type of knowledge did. Thus, subjectively feeling that one understands and is understood by one's partner appears to be more important to relationship well-being than actually knowing and being known by one's partner. © 2009 by the Society for Personality and Social Psychology, Inc

Within-Household Selection Methods: A Critical Review and Experimental Examination

Probability samples are necessary for making statistical inferences to the general population (Baker et al. 2013). Some countries (e.g. Sweden) have population registers from which to randomly select samples of adults. The U.S. and many other countries, however, do not have population registers. Instead, researchers (i) select a probability sample of households from lists of areas, addresses, or telephone numbers and (ii) select an adult within these sampled households. The process by which individuals are selected from sampled households to obtain a probability-based sample of individuals is called within-household (or within-unit) selection (Gaziano 2005).Within-household selection aims to provide each member of a sampled household with a known, nonzero chance of being selected for the survey (Gaziano 2005; Lavrakas 2008). Thus, it helps to ensure that the sample represents the target population rather than only those most willing and available to participate and, as such, reduces total survey error (TSE). In interviewer-administered surveys, trained interviewers can implement a prespecified within-household selection procedure, making the selection process relatively straightforward. In self-administered surveys, within-household selection is more challenging because households must carry out the selection task themselves. This can lead to errors in the selection process or nonresponse, resulting in too many or too few of certain types of people in the data (e.g. typically too many female, highly educated, older, and white respondents), and may also lead to biased estimates for other items. We expect the smallest biases in estimates for items that do not differ across household members (e.g. political views, household income) and the largest biases for items that do differ across household members (e.g. household division of labor). In this chapter, we review recent literature on within-household selection across survey modes, identify the methodological requirements of studying within-household selection methods experimentally, provide an example of an experiment designed to improve the quality of selecting an adult within a household in mail surveys, and summarize current implications for survey practice regarding within-household selection. We focus on selection of one adult out of all possible adults in a household; screening households for members who have particular characteristics has additional complications (e.g. Tourangeau et al. 2012; Brick et al. 2016; Brick et al. 2011), although designing experimental studies for screening follows the same principles
