Occupational differences in work engagement: A longitudinal study among eight occupational groups in Norway

The aim of the present study was to explore occupational differences in the experience of engagement both with regard to differences in the level of work engagement as well as in the predicting value of different antecedent variables. Multigroup latent mean analysis was performed on eight different occupational groups in Norway (lawyers, physicians, nurses, teachers, church ministers, bus drivers, and people working in advertising and information technology; N = 3,475). Tests for factorial invariance supported the use of the Oldenburg Burnout Inventory scale across occupational groups and that the latent means were comparable across the groups. Results indicated significant occupational differences in the experience of vigor and dedication. The lawyers reported the most vigor and the church ministers the most dedication. Least vigor was reported among the teachers and the advertising group reported to be least dedicated. Cross‐lagged multigroup structural equation modeling (SEM) analysis suggested there are different processes behind the development of engagement across occupations. Visualization of how some occupations cluster or differ from each other is important as it might engender theory building and further hypotheses testing.     

Improving Psychological Measurement: Does It Make a Difference? A Comment on Nesselroade and Molenaar (2016)

Nesselroade and Molenaar advocate the use of an idiographic filter approach. This is a fixed-effects approach, which may limit the number of individuals that can be simultaneously modeled, and it is not clear how to model the presence of subpopulations. Most important, Nesselroade and Molenaar's proposal appears to be best suited for modeling long time series on a few variables for a few individuals. Long time series are not common in psychological applications. Can it be applied to the usual longitudinal data we face? These are characterized by short time series (four to five points in time), hundreds of individuals, and dozens of variables. If so, what do we gain? Applied settings most often involve between-individual decisions. I conjecture that their approach will not outperform common, simpler, methods. However, when intraindividual decisions are involved, their approach may have an edge.     

The Combined Effects of Measurement Error and Omitting Confounders in the Single-Mediator Model

Mediation analysis requires a number of strong assumptions be met in order to make valid causal inferences. Failing to account for violations of these assumptions, such as not modeling measurement error or omitting a common cause of the effects in the model, can bias the parameter estimates of the mediated effect. When the independent variable is perfectly reliable, for example when participants are randomly assigned to levels of treatment, measurement error in the mediator tends to underestimate the mediated effect, while the omission of a confounding variable of the mediator-to-outcome relation tends to overestimate the mediated effect. Violations of these two assumptions often co-occur, however, in which case the mediated effect could be overestimated, underestimated, or even, in very rare circumstances, unbiased. To explore the combined effect of measurement error and omitted confounders in the same model, the effect of each violation on the single-mediator model is first examined individually. Then the combined effect of having measurement error and omitted confounders in the same model is discussed. Throughout, an empirical example is provided to illustrate the effect of violating these assumptions on the mediated effect.     

Response to Stuart Kauffman: The Paradox of Divine Action and Scientific Truth

We three authors compare and contrast Stuart Kauffman's concept of the “cosmic mind” with similar ideas developed in our recent book, The Unity of Truth: Solving the Paradox of Science and Religion (IUniverse, 2012). Albert Einstein was known to have said: “Science without religion is lame, religion with science is blind.” We authors make use of the “paradox resolution” methods of physics to find a non-conflicting method by which God's actions communicate with human beings without violating any of the laws of science. The “communications paradox” is resolved by hypothesizing non-causal quantum-mechanical measurements as the way God communicates. the quantum-mechanical resolution of the “communications paradox” is completely consistent with both theist belief and the laws of science, whereas Kauffman's “cosmic mind” concept is seen to be consistent with pantheism.     

Factorial Structure of the Family Values Scale From a Multilevel-Multicultural Perspective

In cross-cultural research, there is a tendency for researchers to draw inferences at the country level based on individual-level data. Such action implicitly and often mistakenly assumes that both the measuring instrument and its underlying construct(s) are operating equivalently across both levels. Based on responses from 5,482 college students sampled from 27 countries, we took a structural equation modeling approach to addressing this issue of level equivalence. Purposes of the study were: (a) to validate the hypothesized two-factor structure of the Family Values Scale (FV Scale; Georgas, 1999) within a multilevel framework that took individual- and country-level information into account; (b) to test equivalence of the FV Scale across individual and country levels; and (c) to evaluate relations between the FV Scale and three possibly important covariates—gender at the individual level, and affluence and religion at the country level. Implications of findings and importance of multilevel equivalence in cross-cultural research are discussed.     

Behavioral methods of assessing forgiveness

One problem in forgiveness research is the reliance on one method (i.e. having people recall an offense and complete self-report measures). Thus, we present two strategies for studying forgiveness-related behavior. First, we adapted the Cyberball paradigm, which is a game of toss where two computer players (ostensibly virtual players) exclude the participant from play. We adapted Cyberball to include a second round that gave participants the opportunity to retaliate or forgive the player who excluded them. Self-reported forgiveness predicted the first toss and total number of tosses to the offender in the subsequent round. Second, we had participants describe an offense (as is typical with the recall method), but then also complete an activity in which they listed as many positive qualities as they could about the offender. Self-reported forgiveness predicted the number of positive qualities listed. We discuss the contribution of these studies to the multimodal study of forgiveness.     

Seven things to consider when measuring religious identity

Measuring religious identity is complex. The author offers seven suggestions for those who wish to describe and understand religious identity using survey data:

• (1)?Definitions and measures of religious identity shape knowledge about religious groups;

• (2)?Variation in question wording leads to variation in responses;

• (3)?Comparing results across surveys provides valuable perspective;

• (4)?Incentives shape how respondents report their religious identity;

• (5)?Religious identity may be liminal;

• (6)?Salient identity categories are often unmeasured; and

• (7)?Religious identity and religious practice may not seem congruent.

This essay includes many examples to illustrate these measurement suggestions.     

Measuring Stereotypes of Female Politicians

One explanation for the dearth of women in elected office is that voters stereotype candidates based on their gender. Research in this vein often assumes that female candidates will be stereotyped similarly to women (e.g., as compassionate) and measures stereotypes as such. We question this assumption, proposing instead that female politicians constitute a subtype—a new stereotypical category with its own qualities—of the broader group of women. We compare the content of female politician stereotypes to other relevant comparison groups including politicians, male politicians, and female professionals. Using a classic methodology to determine stereotype content (Katz & Braly, 1933), we find that female politicians do not share the qualities that are ascribed to women (e.g., warm, empathetic). Our results show that female politicians seem to be “losing” on male stereotypical qualities while also not having any advantage on qualities typical of women. The content of female politician stereotypes is nebulous and lacks clarity in comparison to all other groups examined. We discuss implications for the future measurement of politician stereotypes.     

Stiffness properties of the trunk in people with low back pain

The purpose of this study was to examine the dynamic properties of the trunk during unstable sitting and to determine differences between healthy and low back pain (LBP) participants.Participants sat on a custom-made chair that was able to swing freely in the sagittal plane. The chair was mounted on a force platform to measure loads acting at the trunk. Each participant was asked to find a balanced position after the chair was tilted backward and released. Movements of the trunk and chair were recorded. Effective moment of inertia, stiffness and damping coefficients were derived using a second order linear model. 10 participants were re-tested to assess reliability.Trunk stiffness was found increased for LBP subjects (p < .05) while no difference was found for damping coefficient. Gender and initial tilt angle did not affect viscoelastic properties of the spine.A second order linear model adequately described the biomechanical response of the trunk. It was shown that the trunk response was mainly elastic for all participants. The increase in trunk stiffness in LBP subjects could be a compensatory strategy to decrease pain and the risk of further injuries, but further investigations are needed to understand the nature of the viscoelastic alterations.
