The effect of similarity between owner's values and their perceptions of their pet's values on life satisfaction.

It is often assumed that pet ownership improves peoples' wellbeing, but evidence of this pet effect has been mixed. We extended past research on pet personality, the pet effect, and value congruence to examine whether people perceive their pets to have humanlike values and if owner-pet values similarity has a positive effect on owners' life satisfaction. In a large and diverse sample of Australian dog and cat owners, we find that people imbue their dogs and cats with humanlike values in a way that reflects the theoretical circular structure of values. Importantly, perceptions of the values of dogs and cats differed in that dogs were perceived to prioritize more social-focus values, whereas cats were perceived to prioritize more personal-focus values. Additionally, we find that similarity in the values profile of dog owners and their dogs is positively associated with life satisfaction, but this was not the case for cats. However, when we examined associations between individual values similarity and life satisfaction, our results suggest a more complex and nuanced picture of both direct and indirect similarity effects.

The impact of the COVID-19 pandemic on environmental values.

Environmental values emphasize protection of the natural environment and promote behaviors that express this broad motivational goal. Thus, changes in these values at the community and individual levels are likely to have significant consequences for sustainability efforts. We examined the relative importance of environmental values in Australian adults at five time points over 4 years, including a period of stability (2017-2019) and a period of crisis (early and late in the 2020 COVID-19 pandemic). We found that the relative importance of environmental values increased from 2017 to 2019 and decreased during the pandemic. Importantly, the decrease in 2020 was lessened by individuals' connection with nature.

Value Profiles During Middle Childhood: Developmental Processes and Social Behavior.

Little is known about how children's value priorities develop over time. This study identifies children's value priority profiles and follows their development during middle childhood. Australian children (N = 609; ages 5-12 at Time 1) reported their values over 2 years. Latent Transition Analysis indicated four profiles: Social-Focus, Self-Focus, Growth-Focus and Undifferentiated. Within person development was characterized by profile stability or transfer to the Social-Focus profile. Younger children were more likely to have an Undifferentiated profile (or Self-Focus among boys) than older ones. Girls were more likely to have a Social-Focus profile or transfer to it, and less likely to have a Self- or Growth-Focus profile than boys. Social-Focus profile membership over time predicted more prosocial and less aggressive behavior.

Testing and Extending Schwartz Refined Value Theory Using a Best-Worst Scaling Approach.

The theory of human values discriminated 10 basic values arrayed in a quasicircular structure. Analyses with several instruments in numerous samples supported this structure. The refined theory of human values discriminates 19 values in the same circle. Its support depends on one instrument, the revised Portrait Values Questionnaire. We introduce a forced choice method, the Best-Worst Refined Values scale (BWVr), to assess the robustness of the refined theory to method of measurement and also assess the distinctiveness and validity of a new animal welfare value. Three studies ( N = 784, 439, and 383) support the theory and the new value. Study 3 also demonstrates the convergent and discriminant validity of the 19 values by comparing the BWVr, the revised Portrait Values Questionnaire, and value-expressive behaviors and confirms the test-retest reliability of BWVr responses. These studies provide further information about the order of values in the value circle.

Liver fat: effect of hepatic iron deposition on evaluation with opposed-phase MR imaging.

PURPOSE: To retrospectively determine the effect of liver iron deposition on the evaluation of liver fat by using opposed-phase magnetic resonance (MR) imaging. MATERIALS AND METHODS: Committee on Human Research approval was obtained, and compliance with HIPAA regulations was observed. Patient consent was waived by the committee. Thirty-eight patients with cirrhosis (30 men, eight women; mean age, 58 years; range, 34-76 years) who underwent abdominal MR imaging and had contemporaneous liver biopsy were retrospectively identified. Two radiologists independently quantified liver fat according to the relative loss of signal intensity and compared this loss on opposed-phase and in-phase T1-weighted gradient-echo images. Liver fat percentage and presence of iron deposition were independently recorded by a pathologist. Generalized linear models, which included a mixed-random effects model, were used to determine the effect of iron deposition on the Spearman correlation coefficient for relative signal intensity loss versus histopathologically determined fat percentage. RESULTS: Liver iron deposition was found in 25 of 38 patients. Liver fat percentage (mean, 3%; range, 0%-25%) was identified histopathologically in 14 of 38 patients and in nine of 25 patients with iron deposition. For both readers, relative signal intensity loss at opposed-phase imaging was closely and significantly correlated (P < .05) with histopathologically determined liver fat percentage in patients without iron deposition (r = 0.7 for reader 1, r = 0.6 for reader 2), but no such correlation was found in patients with iron deposition (r = 0.1 for reader 1, r = -0.31 for reader 2; P > .05). CONCLUSION: Signal intensity loss on in-phase images caused by the presence of liver iron is a potential pitfall in the determination of liver fat percentage at opposed-phase MR imaging in chronic liver disease.
