The Importance of the Relevance of the Issue to the Group in Voting Intentions: The Case of the Australian Republic Referendum

This is the author's postprint version of an article whose final and definitive form has been published in the Basic and Applied Social Psychology © 2005 Lawrence Erlbaum Associates, Inc; Basic and Applied Social Psychology is available online at http://www.informaworld.comA questionnaire was distributed on the Australian republic issue to examine the interplay between norms and relevance of the issue to the group on voting intentions. Supporters of an Australian republic (N = 188) indicated the level of support for a republic within their peer group, the relevance of the republic issue to the group, and measures designed to assess voting intentions and other attitude outcomes. Analysis revealed an interaction between normative support and relevance of the issue to the group. On the measure of intention, increasing normative support was associated with increased intention to vote in an attitude-consistent way at both relevance levels, but the effect was heightened when the issue was highly relevant to the group. On the outcomes of willingness to express opinion and perceived personal importance of the republic issue, normative support had a positive effect only when the issue was highly relevant to the group. Mediation analyses revealed that the impact of normative support and group relevance on intention were mediated through perceived personal importance of the republic issue

The validity of the SF-36 in an Australian National Household Survey: demonstrating the applicability of the Household Income and Labour Dynamics in Australia (HILDA) Survey to examination of health inequalities

BACKGROUND: The SF-36 is one of the most widely used self-completion measures of health status. The inclusion of the SF-36 in the first Australian national household panel survey, the Household, Income and Labour Dynamics in Australia (HILDA) Survey, provides an opportunity to investigate health inequalities. In this analysis we establish the psychometric properties and criterion validity of the SF-36 HILDA Survey data and examine scale profiles across a range of measures of socio-economic circumstance. METHODS: Data from 13,055 respondents who completed the first wave of the HILDA Survey were analysed to determine the psychometric properties of the SF-36 and the relationship of the SF-36 scales to other measures of health, disability, social functioning and demographic characteristics. RESULTS: Results of principle components analysis were similar to previous Australian and international reports. Survey scales demonstrated convergent and divergent validity, and different markers of social status demonstrated unique patterns of outcomes across the scales. CONCLUSION: Results demonstrated the validity of the SF-36 data collected during the first wave of the HILDA Survey and support its use in research examining health inequalities and population health characteristics in Australia

Mental health problems among single and partnered mothers: The role of financial hardship and social support

Background: Research has shown elevated levels of common mental disorders among single mothers compared with partnered mothers. The objectives of this analysis were to examine the prevalence of mental health problems among single and partnered mothers and the extent to which this relationship is mediated by socio-demographic, financial and social support variables. Methods: Using cross-sectional data from a large, nationally representative longitudinal Australian household survey - the Household Income and Labour Dynamics in Australia (HILDA) Survey - the prevalence of moderate to severe mental disability (as measured by the SF-36) was assessed among 354 single mothers and 1,689 partnered mothers. A series of univariate and simultaneous logistic regression analyses assessed the association between parenting status, the other explanatory variables and mental disability. Mediational analyses were conducted using the 'explained fraction' approach. Results: The prevalence of moderate to severe mental disability was significantly more pronounced among single mothers (28.7%) compared with partnered mothers (15.7%). Including all explanatory factors-socio-demographic, household income, financial hardship and social support-accounted for 94% of the association between single mother status and poor mental health. Financial hardship and social support were the strongest predictors, accounting for most of the predictive power of the other variables. Conclusions: Single mothers are more likely to experience poor mental health than partnered mothers, and the primary factors associated with this are the presence of financial hardship in particular, as well as perceived lack of social support. Future research should examine the extent to which changes in financial hardship among different family types relate to changes in mental health over time, as well as continue to examine variables that may moderate the relationship between social disadvantage and poor mental health

Developing prospective measures of adversity among Australian families with young children

Most studies of children's development and parents' wellbeing have not dealt effectively with the complexity of multiple disadvantage. Traditional approaches have typically used a limited set of outcomes and predictors. Even studies utilizing multiple ri
