Loneliness and Personality
Objective While loneliness is intertwined with many mental and physical health problems, its origins are not yet well understood. We sought to better understand its link to personality in a large national cohort. Methods Combining self‐ and informant ratings in multiple samples, we conducted the largest study to date to examine loneliness' true correlations ( r true s) with the Big Five personality traits, free of single‐method biases and transie…
Does a Small Country Have Meaningful Regional Personality Differences? The Case of Estonia
BACKGROUND: Regional differences in the Big Five personality domains have been observed in several countries at different geographical granularities, often correlating with regional political, economic, social, and health (PESH) indicators. OBJECTIVE: We examined the extent of regional personality differences in Estonia and whether these differences were meaningfully correlated with PESH indicators. METHODS: Using data from the Estonian Biobank (…
Development and validation of a brief form of the Anticipated Effects of Food Scale
Identifying malleable influences on eating behaviours will advance our ability to improve physical and mental health. Food-related emotional expectancies are the anticipated positive and negative emotions from eating different foods and are theorised to affect eating behaviour, and to be amenable to change. The Anticipated Effects of Food Scale (AEFS) assesses food-related emotional expectancies using 62 one-word items; however, a shorter questio…
Familial similarity and heritability of personality traits and life satisfaction are higher than shown in typical single-method studies
Personality trait similarity among ordinary relatives is surprisingly low, with parent-offspring and sibling-sibling correlations usually r ≤ .15. We explain why these correlations are biased in typical single-method studies and argue that this problem can only be addressed with multimethod designs. We also explain why ordinary relative comparisons can provide a more generalizable way of estimating (additive, narrow-sense) heritability than the b…
The ways of the world? Cross-sample replicability of personality trait-life outcome associations
Across three culturally diverse samples, lower order traits out-predicted multiple life outcomes than broad traits, such as domains. • Predictive accuracy of all levels was stronger in the English-speaking sample. • Narrow traits showed stronger predictive accuracy even when predicting outcomes from culturally different sample – suggesting a degree of universality to findings. • Individual trait associations were slightly more replicable for doma…
Most people's life satisfaction matches their personality traits
70 and its longitudinal associations with personality traits mirrored cross-sectional ones. We conclude that without common measurement limitations, most people's life satisfaction is highly consistent with their personality traits, even across many years. So, satisfaction is usually shaped by these same relatively stable factors that shape personality traits more broadly. (PsycInfo Database Record (c) 2024 APA, all rights reserved)
Body mass predicts personality development across 18 years in middle to older adulthood
OBJECTIVE: Various personality traits have longitudinal relations with body mass index (BMI), a measure of body weight and a risk factor for numerous health concerns. We tested these associations' compatibility with causality in either direction. METHOD: = 53.33 at baseline), we tested how accurately the Five-Factor Model personality domains and their items could collectively predict BMI and change in it with elastic net models. With multilevel m…

Personality traits relate to chronotype at both the phenotypic and genetic level
INTRODUCTION: Diurnal preferences have been linked to personality but often with mixed results. The present study examines the relationships between sleep timing (chronotype), diurnal preferences, and the Five-Factor Model of personality traits at the phenotypic and genetic level. METHODS: = 45.76 years; 59% females). Genetic correlations were obtained through summary statistics of genome-wide association studies. RESULTS: Results showed that hig…

Hunger enhances automatic processing of food and non-food stimuli
Automatic detection of important and unexpected stimuli in the visual environment is crucial for survival. We sought to explore whether visual food stimuli are detected already in the pre-attentive stimulus processing phase, and whether hunger enhances such automatic detection. To attain these goals, we adapted an electroencephalography paradigm - visual mismatch negativity (vMMN). vMMN is a useful paradigm to study the processing of salient emot…
