Item Political polarization and wellbeing: Investigating potential intrapersonal harm From affective polarization(Ubiquity Press, 2025-12-01) McMurtrie B; Roemer A; Philipp M; Hebden R; Williams MAffective polarization—antipathy towards members of one’s political out-group—may pose challenges to social cohesion and personal wellbeing. Prior studies have suggested that one’s affective polarization may cause intrapersonal harm as well as interpersonal harm. It has been associated with reduced social support, increased stress, and worse physical health. This pre-registered study investigated the intrapersonal harm of affective polarization using a six-wave longitudinal survey (N = 470). Affective polarization, social support, perceived stress, and self-rated health were measured fortnightly for three months preceding the 2024 US presidential election. Random intercept cross-lagged panel models were employed to investigate the within-person effects of affective polarization on these indicators of wellbeing. Contrary to hypotheses, none of the hypothesized cross-lagged effects were significant, suggesting that changes in affective polarization did not predict changes in social support, stress, or health. However, cross-sectional analyses did reflect past findings, showing that higher levels of affective polarization were associated with lower social support, greater stress, and worse health. We additionally found evidence for perceived stress causing moderate increases in affective polarization. Stable differences by political orientation were also observed in our sample, with liberals reporting higher affective polarization and stress, lower social support, and worse health. Despite the lack of significant effects, potentially due to limitations such as sample size and measurement constraints, our findings underscore the importance of further investigations with appropriate robust designs to clarify the relationship between affective polarization and wellbeing. These results challenge the assumption that affective polarization directly drives declines in wellbeing.Item Quantifying opponent process dynamics in pornography use and masturbation: An exploratory ecological momentary assessment study(Springer, 2025-11-21) Henry N; Pedersen M; Williams M; Donkin LThe causal relationships between pornography use, masturbation, moral incongruence, and mental health are poorly understood. While the link between problematic pornography use (PPU) and depression is well documented, the temporal dynamics associated with pornography use and masturbation have not yet been quantified. Utilizing an exploratory ecological momentary assessment (EMA) design, we measured the temporal dynamics of cognitive and affective state variables collected from 22 participants before, during, and after pornography use and masturbation, and examined the moderating role of moral incongruence in these relationships. Participants completed an initial survey followed by a four-week EMA, capturing data on sexual activities and cognitive and affective state variables. Bayesian hierarchical mixed-effects models were employed to analyze temporal dynamics. Findings suggest that pornography use and masturbation were linked to changes in affective and cognitive states that spiked both before and after sexual episodes. These states were generally more pronounced and sustained in participants with high moral incongruence, who experienced transient increases in shame, guilt, difficulty thinking, relationship disconnectedness, craving for sexual intercourse, and mood deterioration after pornography use and masturbation. These shifts typically persisted for several hours before decaying to baseline levels. High-incongruence participants also experienced strong spikes in craving prior to sexual episodes, while low-incongruence participants experienced craving spikes after pornography use and masturbation, indicating possible sensitization effects. Our findings also signalled potential evidence for “brain fog” following pornography use in both low and high-incongruence participants. Further, we discovered opponent process dynamics in the mood of high-incongruence participants, providing a possible causal mechanism that may explain how PPU can lead to depression.Item Antecedents of bullying victimisation in adolescents: a fresh look at Aotearoa New Zealand(Taylor & Francis Group, 2024-08-13) Birchall M; Drummond A; Williams MResearch has consistently demonstrated that the prevalence of school bullying in Aotearoa New Zealand exceeds those observed in other developed countries. Despite the need to understand the risk and protective factors for bullying victimisation, there remains a paucity of research in the New Zealand context. The present study aimed to investigate the risk factors for bullying victimisation by conducting a secondary data analysis on a large and representative sample of 15-year-olds from New Zealand using data collected during the 2018 Programme for International Student Assessment (N = 4137). A multiple regression analysis identified eight risk factors which were significantly associated with at least one form of school bullying. The strongest effects indicated that increased parental support and school belonging were associated with lower victimisation, while classroom disorder and school competitiveness were associated with greater victimisation risk. The implications of these findings for future research are discussed.Item Democracy and belief in conspiracy theories in New Zealand(Australian Political Studies Association, 2022) Marques MD; Hill SR; Clarke EJR; Williams M; Ling M; Kerr J; Douglas K; Cichocka A; Sibley CThe COVID-19 pandemic supercharged the spread of fake news, misinformation, and conspiracy theories worldwide. Using a national probability sample of adults from the New Zealand Attitudes and Values Study during 2020 (17–99 years old; M = 48.59, SD = 13.86; 63% women, 37% men; N = 41,487), we examined the associations between agreement with general conspiracy beliefs and political indicators of intention to vote and satisfaction with government, alongside political factors including trust in politicians, political efficacy, identity centrality, and political ideology. Left-wing political ideology, trust in politicians, and political efficacy accounted for most of the explained variance in satisfaction with the government. General conspiracy belief was also a unique contributor to lower satisfaction with the government. We also found a curvilinear relationship between political ideology with heightened belief in conspiracies at both ideological extremes and the centre. Findings are discussed in terms of the consequences of conspiracy belief on democratic engagement.
Item Do stress and anxiety lead to belief in conspiracy theories? [version 1; peer review: 5 approved].(F1000 Research Limited on behalf of Taylor and Francis Ltd., 2023-09-05) Fox N; Williams MConspiracies happen, and some conspiracy theories are warranted by evidence. Nevertheless, a non-trivial proportion of the public express belief in conspiracy theories that are not warranted by evidence. Psychological research has therefore investigated the motives that might lead someone to believe a conspiracy theory even where the available evidence for the theory is weak. Two potential causes that have been proposed in the literature and embedded in theorising are psychological stress and anxiety. Prior studies have provided some evidence that stress and anxiety are positively correlated with belief in conspiracy theories, but it remains unclear whether this apparent effect might be accounted for by plausible confounding variables. Furthermore, there have been few preregistered examinations of the proposed effects of stress and anxiety, rendering it unclear to what degree this proposition has yet been subjected to a severe test. In two preregistered cross-sectional survey studies, we tested whether higher perceived stress and anxiety significantly predicted belief in conspiracy theories while controlling for plausible confounding variables (age, education, subjective social status, and political orientation). We analysed data using structural equation models, allowing measurement error to be explicitly modelled and accounted for. In Study 1 (N =502), a cross-sectional survey of Australasian participants indicated that perceived stress and anxiety did not have significant estimated effects on belief in conspiracy theories. In Study 2 (N =1020), a cross-sectional survey of US participants showed a small significant positive effect of perceived stress, but not anxiety, on belief in conspiracy theories. The present results provide very tentative evidence for an effect of perceived stress on belief in conspiracy theories. However, it is increasingly evident that this effect, if it exists at all, is not large. [version 1; peer review: 5 approved]Item A reproduction of the results of Onyike et al. (2003)(2021) Brown NJL; van Rongen J; van der Velde J; Williams M; Schönbrodt, FDOnyike et al. (2003) analyzed data from a large-scale US-American data set, the Third National Health and Nutrition Examination Survey (NHANES-III), and reported an association between obesity and major depression, especially among people with severe obesity. Here, we report the results of a detailed replication of Onyike et al.’s analyses. While we were able to reproduce the majority of these authors’ descriptive statistics, this took a substantial amount of time and effort, and we found several minor errors in the univariate descriptive statistics reported in their Tables 1 and 2. We were able to reproduce most of Onyike et al.’s bivariate findings regarding the relationship between obesity and depression (Tables 3 and 4), albeit with some small discrepancies (e.g., with respect to the magnitudes of standard errors). On the other hand, we were unable to reproduce Table 5, containing Onyike et al.’s findings with respect to the relationship between obesity and depression when controlling for plausible confounding variables—arguably the paper’s most important results—because some of the included predictor variables appear to be either unavailable, or not coded in the way reported by Onyike et al., in the public NHANES-III data sets. We discuss the implications of our findings for the transparency of reporting and the reproducibility of published results.Item Conceptual replication of Seo (2008), “Self-efficacy as a mediator in the relationship between self-oriented perfectionism and academic procrastination”(12/12/2021) Williams M; Edwards SRIntroduction Self-oriented perfectionism is the tendency to set high standards for oneself and evaluate one’s behaviour accordingly. Based on a study of 692 students in Korea, Seo (2008) reported finding a negative relationship between self-oriented perfectionism and academic procrastination – i.e., the tendency to procrastinate on academic tasks. Furthermore, Seo reported that this relationship was completely mediated by self-efficacy. Seo’s study has been influential in the literature but to our knowledge has not yet been independently replicated. In this study we report a preregistered conceptual replication testing five hypotheses based on Seo’s key findings. Material and methods A detailed preregistration (including data processing and analysis syntax) was lodged in advance of data collection at https://osf.io/xfvd8. Participants were 575 students recruited from OECD countries using prolific.co. Academic procrastination was measured via an adapted version of the Procrastination Assessment Scale – Students, while self-oriented perfectionism was measured via the 5-item self-oriented perfectionism subscale of the Big Three Perfectionism Scale. Self-efficacy was measured via the New General Self-Efficacy Scale. Both ordinary least squares regression and structural equation modelling were used to test hypotheses. Results We found no evidence of a bivariate relationship between self-oriented perfectionism and academic procrastination in either set of analyses. However, we did find evidence of a small and negative indirect effect of self-oriented perfectionism on academic procrastination via self-efficacy. Conclusions We were only able to partially replicate Seo’s key findings, having found no evidence of a negative relationship between self-oriented perfectionism and academic procrastination.Item Levels of measurement and statistical analyses(24/05/2021) Williams MMost researchers and students in psychology learn of S. S. Stevens’ scales or “levels” of measurement (nominal, ordinal, interval, and ratio), and of his rules setting out which statistical analyses are admissible with each measurement level. Many are nevertheless left confused about the basis of these rules, and whether they should be rigidly followed. In this article, I attempt to provide an accessible explanation of the measurement-theoretic concerns that led Stevens to argue that certain types of analyses are inappropriate with data of particular levels of measurement. I explain how these measurement-theoretic concerns are distinct from the statistical assumptions underlying data analyses, which rarely include assumptions about levels of measurement. The level of measurement of observations can nevertheless have important implications for statistical assumptions. I conclude that researchers may find it more useful to critically investigate the plausibility of the statistical assumptions underlying analyses than to limit themselves to the set of analyses that Stevens believed to be admissible with data of a given level of measurement.Item Validating the workplace dignity scale(University of California Press for the Society for the Improvement of Psychological Science (SIPS), 20/07/2020) Scott-Campbell C; Williams MWorkplace Dignity has long been the subject of scholarly enquiry, although until recently the body of research has been dominated by ethnographic work. Recently, Thomas and Lucas (2019) developed the first quantitative, direct measure of perceptions of workplace dignity: the Workplace Dignity Scale (WDS). Given the importance of understanding dignity in the workplace, this study sought to replicate the initial scale validation study conducted by Thomas and Lucas, so as to further test the validity of the WDS and the reliability of the scores it produces. Moreover, the current study contributes to the ongoing methodological reform of psychology towards a transparent and rigorous science by preregistering the method and analysis script prior to collecting data. A large sample of workers (N = 812) from the United States were recruited through Prolific Academic and completed an online questionnaire that included the WDS, as well as theoretically related scales (e.g., workplace incivility). Confirmatory factor analyses indicated that the model specified by Thomas and Lucas had reasonable global fit, although it did not meet all of our criteria for good fit, and estimates of reliability (ωt) indicated that responses to items making up the two subscales of the WDS, Dignity and Indignity, had high internal consistency. Nomological analyses revealed that the Dignity subscale of the WDS was significantly correlated in the expected directions with theoretically related variables. Furthermore, the Dignity and Indignity factors of the WDS were found to highly correlate with one another, and an exploratory analysis suggested that the Indignity factor might be a methodological artefact, posing questions as to whether the two factors are qualitatively different phenomena as was argued by Thomas and Lucas. It is concluded that the WDS is a promising tool for measuring workplace dignity although refinement of the proposed measurement model may be necessary.Item The Experiences of Mothers in a Neonatal Unit and Their Use of the Babble App(1/01/2021) Gibson C; Ross K; Williams M; de Vries NTo better understand the experiences of mothers with an infant admitted to a neonatal unit and ascertain their perspectives on an available information support app, Babble, eight mothers with an infant admitted to a Level II+ neonatal unit were interviewed. Thematic analysis was utilized and responses indicated that mothers of neonates experienced challenges around adapting to the maternal role and managing their expectations of motherhood. Relationships with staff were seen as pivotal in the development of maternal confidence and essential to the overall experience. Mothers prioritized informational support, but how mothers sought out this information depended on their individual needs. Mothers who reported using the Babble app found it to be a helpful supplementary resource, tailorable to their situation. Results suggest that greater staff awareness of parental perspectives and the development of adaptable and diverse resources, ensuring parents are provided with individualized and appropriate care, is needed.
