Mild behavioural impairment (MBI) characterizes later-life emergent and persistent nropsychiatric symptoms linked to greater dementia risk, representing a behavioural manifestation of the underlying neurodegenerative disease for some. The association of MBI with functional ability may therefore reveal subtle functional decline as an additional early risk marker in cognitively unimpaired (CU) older adults. Methods: Baseline data from 1714 CU participants from the CAN-PROTECT study were analyzed. MBI was assessed using the MBI Checklist (MBI-C) (continuous and dichotomized, MBI+ ≥8). Functional ability was assessed using the SAGEA scale capturing instrumental and basic activities. Negative binomial models examined associations between MBI and function, adjusting for demographics, cognition, and physical/sensory limitations. Results: Higher MBI-C scores (count ratio [CR] = 1.07; 95%CI: 1.06-1.07) and MBI+ status (CR = 2.64; 95%CI: 2.36-2.95) were associated with greater global and domain-specific functional impairments. Conclusion: Findings highlight the importance of assessing both behavioural and functional changes in CU adults to identify at-risk individuals for timely interventions.

Linear mixed-effects models controlled for age, sex, ethnicity, and relationship length. IPV victimisation did not significantly change over time, and COVID-19-related variables were not associated with any form of IPV. Brazilian participants reported higher psychological IPV than UK participants, although no country differences emerged for physical or sexual IPV. Cost-inflicting mate-retention strategies were positively associated with all forms of IPV in both countries, with consistently stronger associations in the UK. Attachment avoidance was positively associated with all forms of IPV in Brazil but was negatively associated with psychological and sexual IPV in the UK. Attachment anxiety and benefit-provisioning strategies were associated with psychological IPV in Brazil only. These findings suggest that associations between attachment, mate-retention strategies, and IPV victimisation may vary across cultural contexts, underscoring the value of culturally sensitive approaches to IPV research and intervention.

One of these accounts for words’ serial recall order (SRO) and calculates the correlation between SRO and item-level complexity to operationalise the tendency to name increasingly complex words. We hypothesised this tendency would be altered in individuals with amnestic mild cognitive impairment (aMCI), to reflect lexical-semantic organisational decline resulting from potential functional alterations of perirhinal cortex. We expected aMCI individuals to show higher correlational indices than people with no objective cognitive decline (NOCD) due to these trends being more influenced by word count than overall complexity. Sixty aMCI and 54 NOCD individuals, recruited by the TREDEM initiative and representative of the North-East Italian population were administered a 1-min “animals” CF. Four complexity features were scored: frequency, age-of-acquisition, typicality and graphemic length. Individual z-converted correlation coefficients were calculated between SRO and complexity. The two groups were then compared via uncorrected t-tests, age- and education-corrected ANCOVAs, and further ANCOVAs also correcting for quantitative CF scores. aMCI individuals named fewer words, and words of lower and more variable complexity. They also showed a significantly stronger “SRO-graphemic length” correlation. This emerged from the uncorrected models and from the first set of ANCOVAs. Significant differences in lexical-semantic organisation exist in aMCI. Length is a diagnostically relevant feature of Italian words generated as part of CF. In line with cross-linguistic generalisability of findings, potential mechanisms differentiating phonological and orthographic length in languages with transparent/opaque orthographies are discussed.

This interest is motivated partially by its enhancing effects on well-being outcomes. However, comprehensive international evaluations of the link between nature connectedness and well-being remain sparse. In this registered report, we propose a secondary analysis of previously collected data to examine how individual differences in nature connectedness relate to multiple aspects of well-being (i.e., purpose in life, hope, mindfulness, life satisfaction, and optimism) across 75 countries (N = 36,803). Within-country and between-country analyses (linear and mixed regressions) suggested that nature connectedness is a robust positive predictor of well-being. Our findings highlight the importance of nature connected for well-being globally, especially for communities with low access to nature and social resources.
