We present a psychometric test of life history theory as applied to human individual differences using MIDUS survey data (Brim et al. 2000). Twenty scales measuring cognitive and behavioral dimensions theoretically related to life history strategy were constructed using items from the MIDUS survey. These scales were used to construct a single common factor, the K-factor, which accounted for 70% of the reliable variance. The scales used included measures of personal, familial, and social… Expand
A General Factor of Personality From Multitrait–Multimethod Data and Cross–National Twins
The results indicate that the GFP is practically the same in both test batteries, and its existence does not depend on being extracted using the Big Five model. Expand
Life history strategy, identity consolidation, and psychological well-being
Abstract Previous research has shown that individual differences in life history strategies co-vary with a large array of variables to the extent that latent variables from a number of psychologicalExpand
The Genetics of Personality and Well-Being in a Representative Sample
Subjective well-being is known to be related to personality traits. However, to date, nobody has examined whether personality and subjective well-being share a common genetic structure. We used aExpand
The genetics and evolution of the general factor of personality
Three studies tested the hypothesis that a general factor of personality (GFP) underlies diverse individual differences including altruism, the Big Five factors of Openness, Conscientiousness,Expand
Psychometrics and Life History Strategy: The Structure and Validity of the High K Strategy Scale
Concerns are raised about the use of psychometric indicators of lifestyle and personality as proxies for life history strategy when they have not been validated against objective measures derived from contemporary life history theory and when their status as causes, mediators, or correlates has not been investigated.

General Factor of Personality Questionnaire (GFPQ): Only one Factor to Understand Personality?
The General Factor of Personality Questionnaire is presented to measure the basic, combined trait of the complete personality and shows adequate internal consistency and construct validity, while the relationships with the personality factors of other models and with psychopathology are as expected.

The Structure of the Mini-K and K-SF-42 : A Psychological Network Approach.
It is proposed that network analysis, as an alternative to latent variable modeling, offers considerable potential to test hypotheses about the input-output mappings of specific evolved psychological mechanisms. Expand
Overlap Between the General Factor of Personality and Emotional Intelligence: A Meta-Analysis
Findings show that high-GFP individuals score higher on trait and ability EI, supporting the notion that the GFP is a social effectiveness factor and suggesting that theGFP is very similar, perhaps even synonymous, to trait EI. Expand
The General Factor of Personality and general intelligence : Testing hypotheses from Differential-K, Life History Theory, and strategic differentiation-integration effort
Life history as applied to human psychology has progressed on different levels of analysis including between racial groups (Differential-K) and between individuals (Life History Theory). While theExpand
The General Factor of Psychosocial Development and its relation to the General Factor of Personality and Life History strategy
Abstract It was hypothesized that the eight Eriksonian psychosocial stages form a single latent variable or General Factor of Psychosocial Development (GFPD) and that this latent factor is associatedExpand


The K-factor: Individual differences in life history strategy
Abstract Until recently, variations in life history strategy were studied exclusively at the species level. Although this domain of study has been extended to examine systematic differences in lifeExpand
Big Five or Big Two? Superordinate factors in the NEO Five Factor Inventory and the Antisocial Personality Questionnaire
Although it is claimed that the Big Five dimensions of Neuroticism, Extraversion, Openness, Agreeableness, and Conscientiousness represent the highest level in the hierarchical structure ofExpand
A comparison of three structural models for personality: the big three
The major factors from 3 models of personality are compared: Eysenck's Three Factor model, Costa and McCrae's version of the Big Five, and Zuckerman and Kuhlman's Alternative Five. The 1st studyExpand

Differential K theory: The sociobiology of individual and group differences
Abstract Differential K Theory is proposed to help systematize individual and group differences in life histories, social behaviour and physiological functioning. K refers to one end of a continuumExpand
The Ideal Romantic Partner Personality
Most contemporary social psychological studies on inter-personal attraction have independently explored the competing concepts of similarity and complementarity. Incorporating evolutionary principlesExpand
Subjective well-being is heritable and genetically correlated with dominance in chimpanzees (Pan troglodytes).
The hypothesis that subjective well-being (SWB) is heritable and genetically correlated with Dominance was tested and findings indicate that common genes may underlie the correlation between human personality factors and SWB. Expand
Placing intelligence into an evolutionary framework or how g fits into the r-K matrix of life-history traits including longevity
The theoretical importance of the r–K formulation in restoring the concept of bprogressQ to its proper place in evolutionary biology is demonstrated showing why, over the last 575 million years of evolutionary competition of finding and filling new niches, there has always been (and likely always will be) broom at the top.

Contribution of psychosocial factors to socioeconomic differences in health.
The results suggest that a set of both early and current life circumstances cumulatively contribute toward explaining why people of lower socioeconomic status have worse health and lower psychological well-being. Expand
Adaptive Individual Differences
Individuals differ in innumerable ways, some adaptive, some maladaptive, and some neutral. Personality theories, we argue, can profit from distinguishing among these importantly different types ofExpand
