Caregiver Burdens of Family Members with Alzheimer's Disease.

Alzheimer's disease is a common form of dementia characterized by progressive deterioration of a patient's cognitive abilities and memory. Most individuals that have Alzheimer's disease live and depend on family members for assistance or total care. This descriptive, correlational study examines the relationship between perceived caregiver burden of a family member with Alzheimer's disease who attended an adult day care center and perceived caregiver burden of a family member that did not attend an adult day care center.

The hierarchical structure of childhood personality in five countries: continuity from early childhood to early adolescence.

Childhood personality is a rapidly growing area of investigation within individual differences research. One understudied topic is the universality of the hierarchical structure of childhood personality. In the present investigation, parents rated the personality characteristics of 3,751 children from 5 countries and 4 age groups.

Correlation of the experience of peer relational aggression victimization and depression among African American adolescent females.

Problem: This study aimed to examine if the experience of peer relational aggression victimization (PRAV) can be linked to feelings of depression in the African American adolescent female population.

Methods: The sample included 241 college-age African American adolescent females assessed for PRAV and depression. Statistical analysis was carried out to determine the relationship between the variables.

Scoring the DSM-IV personality disorders using the Five-Factor Model: development and validation of normative scores for North American, French, and Dutch-Flemish samples.

Five-Factor Model (FFM) personality disorder (PD) counts have demonstrated significant convergent and discriminant validity with DSM-IV PD symptoms. However, these FFM PD counts are of limited clinical use without normative data because it is difficult to determine what a specific score means with regard to the relative level of elevation. The current study presents data from three large normative samples that can be used as norms for the FFM PD counts in the respective countries: United States (N = 1,000), France (N = 801), and Belgium-Netherlands (N = 549).

Adolescent personality: a five-factor model construct validation.

The purpose of this study was to investigate convergent and discriminant validity of the five-factor model of adolescent personality in a school setting using three different raters (methods): self-ratings, peer ratings, and teacher ratings. The authors investigated validity through a multitrait-multimethod matrix and a confirmatory factor analysis correlated trait, uncorrelated method model. With the exception of Emotional Stability, each analysis demonstrated similar patterns and together provided support for the convergent and discriminant validity of the five-factor model structure of adolescent personality.

Personality structure as derived from parental ratings of free descriptions of children: the inventory of child individual differences.

Based on over 50,000 parental descriptors of children gathered in eight different countries, we used a combination of focus group sorting of descriptors in each country and factor analyses of instruments developed in four of the countries (United States, China, Greece, and the Netherlands) to describe children ages 3 to 12 years to select items for an instrument that would work well across countries to access personality. Through many factor analyses of indigenous items in each country, a core set of 141 items was used in three of the countries, with over 3000 parents responding to our instruments in China, Greece, and the United States. Much cross-comparative research analysis has resulted in 15 robust midlevel scales that describe the structures of parental descriptors that are common to the three countries.
