Research on adulthood posits personality and self-esteem as important predictors of psychopathology. In childhood, however, the study of these relationships is complicated by the lack of consensus on how to combine data from multiple informants of child behavior. This study evaluates the relationships among personality symptoms, self-esteem and psychopathology in 60 child psychiatric patients (M (age) = 10.6) using principal component analysis (PCA) to aggregate data from multiple informants and compares this strategy with a single informant approach. When predictor and criterion measures were rated by a single informant, strong and differential relationships between personality symptoms, self-esteem and psychopathology are found. When multiple informant data were combined into composite scores by PCA, correlations decreased but remained significant. Hierarchical regression analyses affirm the robustness of the following pattern: Emotional Instability, Introversion and Global Self-Esteem are associated with internalizing whereas Disagreeableness and Behavioral Conduct primarily relate to externalizing problems.

Erikson's concepts of stagnation and generativity were investigated in two studies. Study 1 (N=457) yields two important results. First, it revealed that a model in which stagnation and generativity load on a separate dimension showed a significantly better fit to the data than a one-dimensional model. Second, the stagnation and generativity measures were valid predictors of parental behavior. In Study 2 (N=191), the relationships between stagnation and generativity and the dimensions underlying comprehensive measures of personality were investigated. It was found that stagnation was strongly related to Neuroticism, Extraversion, and Openness to Experience, whereas generativity bore strong relationships with Extraversion, Conscientiousness, and Openness to Experience. In the discussion, stagnation is distinguished from several related variables and a profile of the stagnant individual is constructed and compared with the generative individual. Finally, the interaction between stagnation and generativity in producing specific outcomes is discussed.

According to optimal distinctiveness theory, minority political parties and parties of intermediate size provide more central and important bases of social identity. The authors tested that prediction in a sample of voters and a sample of political party members. In both samples, adherents of minority and intermediate parties did not perceive their parties to be more representative of them. The authors found no significant differences between political parties on the collective self-esteem questionnaire administered to the sample of political party members.

Explored the relationship between obesity and psychosocial adjustment in a combined clinical and nonclinical sample of 139 obese children and 150 non-obese children (ages from 9 to 12 years and matched for age, socioeconomic status, and gender) who filled out the Perceived Competence Scale for Children; their parents completed the Child Behavior Checklist. All obese children, independent of their help-seeking status, reported more negative physical self-perceptions than their nonobese peers and they scored lower on general self-worth. According to their parents, the obese children of the clinical sample appeared to have more behavior problems. Findings suggest that psychopathology depends on a clinical obese status, and they provide evidence for a psychosocial at-risk profile for a subgroup of obese children.
