Demographic and Psychological Predictors of Panel Attrition: Evidence from the New Zealand Attitudes and Values Study

This study examines attrition rates over the first four years of the New Zealand Attitudes and Values Study, a longitudinal national panel sample of New Zealand adults. We report the base rate and covariates for the following four distinct classes of respondents: explicit withdrawals, lost respondents, intermittent respondents and constant respondents. A multinomial logistic regression examined an extensive range of demographic and socio-psychological covariates (among them the Big-Six personality traits) associated with membership in these classes (N = 5,814). Results indicated that men, Māori and Asian peoples were less likely to be constant respondents. Conscientiousness and Honesty-Humility were also positively associated with membership in the constant respondent class. Notably, the effect sizes for the socio-psychological covariates of panel attrition tended to match or exceed those of standard demographic covariates. This investigation broadens the focus of research on panel attrition beyond demographics by including a comprehensive set of socio-psychological covariates. Our findings show that core psychological covariates convey important information about panel attrition, and are practically important to the management of longitudinal panel samples like the New Zealand Attitudes and Values Study.

Personality Resilience Following a Natural Disaster

We examine changes in the Big Six personality markers (Extraversion, Agreeableness, Conscientiousness, Emotional Stability, Openness to Experience, and Honesty–Humility) before and after the 2010/2011 Christchurch earthquakes in a longitudinal study of New Zealand residents (N = 3,914). Results show remarkable stability in personality, save for one exception: Those who were affected by the earthquakes evidenced a slight decrease in Emotional Stability over the 2-year test–retest period relative to those unaffected by the earthquakes. These findings indicate that most aspects of personality are resilient following a major natural disaster. The slight decrease in Emotional Stability, however, points to a possible increase in vulnerability to depression and anxiety for those affected by the earthquakes. Our study provides important insights into a central question about stability and change in personality following major life events.

Normative personality trait development in adulthood:: A 6-year cohort-sequential growth model.

The present study investigated patterns of normative change in personality traits across the adult life span (19 through 74 years of age). We examined change in extraversion, agreeableness, conscientiousness, neuroticism, openness to experience and honesty-humility using data from the first 6 annual waves of the New Zealand Attitudes and Values Study (N = 10,416; 61.1% female, average age = 49.46). We present a cohort-sequential latent growth model assessing patterns of mean-level change due to both aging and cohort effects. Extraversion decreased as people aged, with the most pronounced declines occurring in young adulthood, and then again in old age. Agreeableness, indexed with a measure focusing on empathy, decreased in young adulthood and remained relatively unchanged thereafter. Conscientiousness increased among young adults then leveled off and remained fairly consistent for the rest of the adult life span. Neuroticism and openness to experience decreased as people aged. However, the models suggest that these latter effects may also be partially due to cohort differences, as older people showed lower levels of neuroticism and openness to experience more generally. Honesty-humility showed a pronounced and consistent increase across the adult life span. These analyses of large-scale longitudinal national probability panel data indicate that different dimensions of personality follow distinct developmental processes throughout adulthood. Our findings also highlight the importance of young adulthood (up to about the age of 30) in personality trait development, as well as continuing change throughout the adult life span.

Stability and Change in Political Conservatism Following the Global Financial Crisis

The current study analyzes data from a national probability panel sample of New Zealanders (N = 5,091) to examine stability and change in political orientation over four consecutive yearly assessments (2009-2012) following the 2007/2008 global financial crisis. Bayesian Latent Growth Modeling identified systematic variation in the growth trajectory of conservatism that was predicted by age and socio-economic status. Younger people (ages 25-45) did not change in their political orientation. Older people, however, became more conservative over time. Likewise, people with lower socio-economic status showed a marked increase in political conservatism. In addition, tests of rank-order stability showed that age had a cubic relationship with the stability of political orientation over our four annual assessments. Our findings provide strong support for System Justification Theory by showing that increases in conservatism in the wake of the recent global financial crisis occurred primarily among the poorest and most disadvantaged.

Values Stability and Change in Adulthood: A 3-Year Longitudinal Study of Rank-Order Stability and Mean-Level Differences

Recent studies have examined whether values change across time. The present study investigates both rank-order stability and mean-level differences in core values—and whether age and sex moderate stability and change—over 3 years using a national probability sample (from 25 to 75 years; N = 3,962). Value priorities were highly stable, except for Conservation values among women, which peaked in stability at age 50 and decreased afterward. Older adults and women placed greater emphasis on values relating to the welfare of others and preservation of traditional practices and stability (Self-Transcendence and Conservation values). Younger individuals and men tended to more highly value the pursuit of status and power, and independent thought and behavior (Self-Enhancement and Openness to Change). The results are consistent with a life span perspective on values development and indicate values may change slowly throughout life as a reflection of biological and psychological maturation.

Authoritarianism and National Identity: Examining the Longitudinal Effects of SDO and RWA on Nationalism and Patriotism

The resurgence of right-wing political parties across the globe raises questions about the origins of national identity. Based on the Dual Process Model of Ideology and Prejudice, we argue that people’s tendency to submit to ingroup authorities (Right-Wing Authoritarianism [RWA]) and preference for group-based hierarchy (Social Dominance Orientation [SDO]) underlie people’s belief in the superiority of their nation (nationalism) and attachment to their homeland (patriotism). We examine these hypotheses using three waves of data from an annually conducted national longitudinal panel study of New Zealanders (N = 3,838). As predicted, RWA had positive cross-lagged effects on nationalism and patriotism. Conversely, SDO had a positive cross-lagged effect on nationalism, but a negative cross-lagged effect on patriotism. Little evidence of reciprocal cross-lagged effects (i.e., national identity on authoritarianism) was found. These results demonstrate that nationalism and patriotism are related, albeit distinct, ways of identifying with one’s nation that are ultimately rooted in authoritarianism.

Regional Differences in the Psychological Recovery of Christchurch Residents Following the 2010/2011 Earthquakes: A Longitudinal Study

We examined changes in psychological distress experienced by residents of Christchurch following two catastrophic earthquakes in late 2010 and early 2011, using data from the New Zealand Attitudes and Values Study (NZAVS), a national probability panel study of New Zealand adults. Analyses focused on the 267 participants (172 women, 95 men) who were living in central Christchurch in 2009 (i.e., before the Christchurch earthquakes), and who also provided complete responses to our yearly panel questionnaire conducted in late 2010 (largely between the two major earthquakes), late 2011, and late 2012. Levels of psychological distress were similar across the different regions of central Christchurch immediately following the September 2010 earthquake, and remained comparable across regions in 2011. By late 2012, however, average levels of psychological distress in the regions had diverged as a function of the amount of property damage experienced within each given region. Specifically, participants in the least damaged region (i.e., the Fendalton-Waimairi and Riccarton-Wigram wards) experienced greater drops in psychological distress than did those in the moderately damaged region (i.e., across the Spreydon-Heathcote and Hagley-Ferrymead wards). However, the level of psychological distress reported by participants in the most damaged region (i.e., across Shirley-Papanui and Burwood-Pegasus) were not significantly different to those in the least damaged region of central Christchurch. These findings suggest that different patterns of psychological recovery emerged across the different regions of Christchurch, with the moderately damaged region faring the worst, but only after the initial shock of the destruction had passed.

Are People Becoming More Entitled Over Time? Not in New Zealand

It is a common conception that entitlement is increasing among younger generations over time. However, although there is some evidence for this trend, other findings are less conclusive. The current research investigated change in psychological entitlement across the adult lifespan for men and women (ages 19-74), using six annual waves of data (2009-2014) from the New Zealand Attitudes and Values Study (N = 10,412). We employed Cohort-Sequential Latent Growth Modeling to assess mean-level change in entitlement. Entitlement was found to be generally unchanging over time for both men and women, with only those aged 65 and above showing increasing entitlement. Entitlement showed a steady downward trend across age. These findings from a large national probability sample suggest that change in entitlement may follow a decreasing developmental trend across the lifespan. In New Zealand, at least, there is no evidence for a narcissism epidemic.

Benevolent Sexism and Hostile Sexism Across the Ages

Ambivalent sexism theory states that prejudice toward women comprises two interrelated ideologies. Endorsement of hostile sexism—aggressive and competitive attitudes toward women—is linked with endorsement of benevolent sexism—paternalistic and patronizing attitudes toward women. We conduct the first systematic tests of how endorsement of sexism differs across age and across time, using six waves of a nationally representative panel sample of New Zealand adults (N = 10,398). Results indicated U-shaped trajectories for men’s endorsement of hostile sexism, women’s hostile sexism, and women’s benevolent sexism across the life span. However, over time, endorsement of these sexist attitudes tended to decrease for most ages. In contrast, men’s benevolent sexism followed a positive linear trajectory across age and tended not to change over time. These results provide novel evidence of how ambivalent sexism differs across age and highlight that benevolent sexism is particularly tenacious.

Ingroup friendship and political mobilization among the disadvantaged.

This study investigated the effects of ingroup contact in a large, national sample of Māori (a disadvantaged ethnic group; N = 940) on political attitudes relevant to decreasing ethnic inequality in New Zealand. We tested the role of 2 mediating mechanisms-ethnic identification and system justification-to explain the effects of ingroup contact on the dependent variables. Time spent with ingroup friends predicted increased support for the Māori Party and support for symbolic and resource-specific reparative policies benefiting Māori. These effects were partially mediated by increased ethnic identification. Although ingroup contact also reduced levels of system justification among Māori, its effects on policy attitudes and party preference were not mediated by system justification. This suggests that a key antecedent to system challenging political attitudes is an increased sense of identification with a disadvantaged group resulting, in part, from interactions with ingroup friends.
