Youthful smoking and drinking in a longitudinal perspective.
1982
The incidence and continuity of smoking and drinking, precursory social-behavioral characteristics of smokers and drinkers, and life conditions related to smoking and drinking are described. The study was part of an extensive Finnish longitudinal study of social development, the original sample of which consisted of 8-year-old subjects (196 boys, 173 girls) studied in 1968 by employing peer nomination and teacher ratings. The follow-up studies were made at ages 14 and 20. 154 Ss at age 14 and 135 Ss at age 20 were interviewed about their smoking and drinking habits, among others. The results showed that about 20% of the subjects smoked at age 14 and about 30% at age 20. The proportion of ab…
Toward an understanding of a healthy organizational change process : A three-wave longitudinal study among university employees
2019
This study aimed to improve our understanding of what constitutes a healthy organizational change process among university employees. Positive attitudes and proactive participation toward organizational change were presumed to affect and be affected by personality resources measured via core self-evaluations and work-related motivational well-being (vigor). The study used 3-wave longitudinal data collected in 2 large Finnish universities during their recent process of organizational change (N = 926). Structural equation modeling was used to establish the direction of the relationships between the variables. The results showed that high levels of both core self-evaluations and vigor were ass…
Is there a linkage between metabolism and personality in small mammals? The root vole (Microtus oeconomus) example
2010
Significant inter-individual variation in the rate of animal metabolism is a widespread phenomenon that has started to accumulate general interest. Here we follow recent calls to focus on linkage between the variation in energy metabolism and animal personality. By using wild caught root voles as a study species, we examined the relationship between the behavioral patterns (assessed in open field test) and resting metabolic rate (RMR), both of which are known to show large individual differences and intra-individual consistency in voles. Our results showed only a weak relationship between personality traits and metabolism, since the most parsimonious model (according to AICc) explaining RMR…
A field test of behavioural flexibility in Zenaida doves (Zenaida aurita).
2010
7 pages; International audience; Animals' ability to adjust their behaviour when environmental conditions change can increase their likelihood of survival. Although such behavioural flexibility is regularly observed in the field, it has proven difficult to systematically quantify and predict inter-individual differences in free-living animals. We presented 24 Zenaida doves (Zenaida aurita) on 12 territories with two learning tests in their natural habitat in Barbados. The dove pairs showed high site fidelity and territoriality, allowing us to test individuals repeatedly while accounting for the effects of territorial chases and pair bonds on our learning measures. We used a foraging apparat…
Get some respect – buy organic foods! When everyday consumer choices serve as prosocial status signaling
2020
Status considerations have recently been linked to prosocial behaviors. This research shows that even everyday consumer behaviors such as favoring organic foods serve as prosocial status signaling. Key ideas from the continuum model of consumer impression formation and the theories of costly signaling and symbolic consumption are synthetized to make sense of this phenomenon. Two web-surveys (Ns = 187, 259) and a field study (N = 336) following experimental designs are conducted. This approach allows the analysis of both the more and less conscious reactions of consumers. Study 1 shows that the image of consumers favoring organic product versions is marked by characteristics consistent with …
Genetic contribution to the relationship between personality and depressive symptoms among older women.
2009
BackgroundPrior studies suggest that certain types of personality are at higher risk for developing depressive disorders. This study examined the relationship between old age depressive symptoms and two middle-age personality dimensions, neuroticism and extraversion.MethodThe present study is part of the Finnish Twin Study on Aging, where altogether 409 female twins who had completed the Eysenck Personality Inventory at the age of 38–51 years were studied for depressive symptoms 28 years later using Center for the Epidemiologic Studies Depression Scale. Logistic regression analysis suitable for dependent data and univariate and Cholesky models for decomposing the genetic and environmental f…
Prevalence and determinants of online-sex use in the German population.
2017
Introduction The unlimited access to sexual features in the World Wide Web has raised concerns about excessive and problematic online-sex use. However, little is known about antecedents of internet-sex use of different intensity. Based on a representative German sample of 2,522 participants between the ages of 14 and 97 years, the aims of the present study were (1) to determine the prevalence rates of online-sex users with the short version (ISSTGSV) of the Internet Sex Screening Test and (2) to associate online-sex use with anxious vs. avoidant partner attachment patterns and “Big Five” personality traits as potential antecedents. Results The ISST is a brief, one-dimensional and reliable m…
Psychological flexibility mediates change in intuitive eating regulation in acceptance and commitment therapy interventions
2017
AbstractObjectiveDespite the promising results related to intuitive eating, few studies have attempted to explain the processes encouraging this adaptive eating behaviour. The focus of the present study was on exploring mechanisms of change in intuitive eating and weight in acceptance and commitment therapy (ACT) interventions. Mediation provides important information regarding the treatment processes and theoretical models related to specific treatment approaches. The study investigates whether psychological flexibility, mindfulness skills and sense of coherence mediated the interventions’ effect on intuitive eating and weight.DesignSecondary analysis of a randomized control trial. Mediati…
Psychometric properties of the Spanish version of the involvement evaluation questionnaire in caregivers of patients with borderline personality diso…
2018
The involvement evaluation questionnaire (IEQ) was created to evaluate the caregiver's experience of burden and the consequences of providing care to people with psychotic disorders. To date, the IEQ has not been validated with caregivers of people diagnosed with borderline personality disorder (BPD). The main objective of the study was to confirm the psychometric properties and factorial structure of the Spanish version of the IEQ in 151 caregivers of people with BPD, with an average age of 54.52 (SD = 9.91). Two models were tested by means of confirmatory factor analysis, following the original factor structure. The Models 1 and 2 displayed adequate fit, with comparative fit index and Tuc…
The relationship between ADHD and key cognitive phenotypes is not mediated by shared familial effects with IQ
2011
BackgroundTwin and sibling studies have identified specific cognitive phenotypes that may mediate the association between genes and the clinical symptoms of attention deficit hyperactivity disorder (ADHD). ADHD is also associated with lower IQ scores. We aimed to investigate whether the familial association between measures of cognitive performance and the clinical diagnosis of ADHD is mediated through shared familial influences with IQ.MethodMultivariate familial models were run on data from 1265 individuals aged 6–18 years, comprising 920 participants from ADHD sibling pairs and 345 control participants. Cognitive assessments included a four-choice reaction time (RT) task, a go/no-go task…
