Mental disorders in childhood or adolescence and subsequent comprehensive school achievement
BACKGROUND: Childhood mental disorders are associated with poorer school achievement, with potential negative long-term socio-economic consequences, but few large-scale studies have examined this association, particularly the role of age at onset. Using a nationwide Finnish cohort, we examined the associations between mental disorders and school achievement, focusing on gender and age at onset. METHODS: This nationwide cohort study used data from…
Validation of the Finnish extra short five 30-item personality scale in a nationally representative sample
This study investigated validity of the Finnish version of the Extra Short Five self-report questionnaire (XS5), a short, 30-item scale measuring personality according to the Five Factor Model (FFM). It utilized a nationally representative sample of 1007 Finnish adults. We evaluated structural validity, internal consistency reliability, convergent and discriminant validity, and criterion-related validity. We also examined the presence of response…
Household income and first psychiatric hospital admissions among children and adolescents
BACKGROUND: Parental socioeconomic factors are associated with mental health outcomes already during childhood, but gender differences in these connections have rarely been studied. AIMS: We explored the associations between household income and severe mental health disorders requiring psychiatric inpatient hospital care, with particular focus on gender differences. METHODS: In this national register-based cohort study, we followed over 1.6 milli…
Loneliness and social isolation in transitions to adverse health conditions and mortality
BACKGROUND: Adverse health conditions may serve as intermediate states linking loneliness and social isolation with excess mortality. We examined whether loneliness and social isolation are primarily associated with the risk of developing an adverse health condition or with prognosis after diagnosis. METHODS: A cohort of 236 879 individuals from the UK Biobank was followed from baseline in 2006-2010 until death or administrative end of follow-up …
Variation in patient-sharing network characteristics of health care professionals treating different mental and substance use disorder patient sub-groups in primary care
BACKGROUND: Providing efficient and targeted services for patients with mental health problems requires efficient collaboration and coordination within healthcare providers, but measuring collaboration using traditional methods is challenging. AIMS: To explore the patient-sharing networks of professionals taking care of different groups of patients with mental or substance use disorders. METHOD: We used data that covered adult patients' visits to…
Families with Internationally Adopted Children in Finland
A well-functioning parent-child relationship is crucial for the child's psychological development. We examined the Emotional Availability (EA) in the early interaction of internationally adopted children with their mothers. We also studied whether the quality of the interaction was associated with the sex of the adopted children, the age at the time of adoption, the time they had spent in the family and parental depressive symptoms. The study sam…
The gateway to the teacher profession
In this longitudinal study, we compared the temperament traits of 1023 teacher applicants and 120 admitted student teachers, and examined whether temperament traits were associated with the student teachers' achievement during the first year of teacher education. Student teachers scored higher in reward dependence and lower in emotionality than the applicants who were not admitted. Similarly, higher reward dependence and lower emotionality were a…
Socioeconomic position at the age of 30 and the later risk of a mental disorder
BACKGROUND: A study was undertaken to examine the association between multiple indicators of socioeconomic position (SEP) at the age of 30 and the subsequent risk of the most common mental disorders. METHODS: All persons born in Finland between 1966 and 1986 who were alive and living in Finland at the end of the year when they turned 30 were included. Educational attainment, employment status and personal total income were used as the alternative…
Do the Temperamental Characteristics of Both Mother and Child Influence the Well-Being of Adopted and Non-Adopted Children
(1) Background: For decades, the temperaments of infants and small children have been a focus of studies in human development and been seen as a potential contributor to children's developmental patterns. However, less is known about the interplay between the temperamental characteristics of mothers and their children in the context of explaining variations in developmental outcomes. The aim of our study was to explore the associations-with or wi…
Living alone as a risk factor for cancer incidence, case-fatality and all-cause mortality
Lack of social contacts has been associated with an increased risk of cancer mortality, but it is not known whether living alone increases the risk of cancer incidence or case fatality. We examined the association between living alone with cancer incidence, case-fatality and all-cause mortality in eight most common cancers. All patients with their first cancer diagnosis in 2000-2017 were identified from the nationwide Finnish Cancer Registry. Inf…
Personality, disability‐free life years, and life expectancy
OBJECTIVE: We examined how personality traits of the Five Factor Model were related to years of healthy life years lost (mortality and disability) for individuals and the population. METHOD: Participants were 131,195 individuals from 10 cohort studies from Australia, Germany, the United Kingdom, and the United States (n = 43,935 from seven cohort studies for the longitudinal analysis of disability, assessed using scales of Activities of Daily Liv…
Temperament profiles are associated with dietary behavior from childhood to adulthood
Role of personality traits in healthy ageing
The role of personality in health has been under speculation for decades. The rise of coherent theories of personality and the inclusion of modern personality trait measures in large-scale epidemiological studies has only rather recently enabled to examine this question profoundly. Numerous studies have shown that from the five major personality traits, conscientiousness—describing individual differences, for example, in self-regulation, orderlin…
A network approach to the analysis of psychosocial risk factors and their association with health
We modeled early psychosocial risks as a network of interconnected variables to study their associations with later depressive symptoms and cardiometabolic outcomes. The participants were a nationally representative sample of 2580 men and women aged 3-18 years in 1980. Their parents reported the psychosocial risks in 1980, including the following: (1) child-specific life events, (2) parental health behavior, (3) parental socioeconomic status, and…
Contribution of risk factors to excess mortality in isolated and lonely individuals
BACKGROUND: The associations of social isolation and loneliness with premature mortality are well known, but the risk factors linking them remain unclear. We sought to identify risk factors that might explain the increased mortality in socially isolated and lonely individuals. METHODS: We used prospective follow-up data from the UK Biobank cohort study to assess self-reported isolation (a three-item scale) and loneliness (two questions). The main…
Childhood Psychosocial Cumulative Risks and Carotid Intima-Media Thickness in Adulthood
OBJECTIVE: Adverse experiences in childhood may influence cardiovascular risk in adulthood. We examined the prospective associations between types of psychosocial adversity and having multiple adversities (e.g., cumulative risk) with carotid intima-media thickness (IMT) and its progression among young adults. Higher cumulative risk score in childhood was expected to be associated with higher IMT and its progression. METHODS: Participants were 226…
Structural and functional aspects of social support as predictors of mental and physical health trajectories
BACKGROUND: Social support is associated with better health. However, only a limited number of studies have examined the association of social support with health from the adult life course perspective and whether this association is bidirectional. METHODS: Participants (n=6797; 30% women; age range from 40 to 77 years) who were followed from 1989 (phase 2) to 2006 (phase 8) were selected from the ongoing Whitehall II Study. Structural and functi…
Personality and Health
Personality and Depressive Symptoms: Individual Participant Meta-Analysis of 10 Cohort Studies
Childhood and adolescence risk factors and development of depressive symptoms
BACKGROUND: Environmental risks in childhood have been shown to predict later depressive symptoms. In this study, we examined whether various environmental risk domains in childhood and adolescence, socioeconomic, psychoemotional, parental lifestyle and life-events, predict depressive symptom trajectories in adulthood individually by domain and as a cumulative risk score across domains. METHODS: Participants were a nationally representative sampl…
