The dependability of the general factor of intelligence: Why small, single-factor models do not adequately represent g

Floyd, Shands, Rafael, Bergeron and McGrew (2009) used generalizability theory to test the reliability of general-factor loadings and to compare three different sources of error in them: the test battery size, the test battery composition, the factor-extraction technique, and their interactions. They found that their general-factor loadings were moderately to strongly dependable. We replicated the methods of Floyd et al. (2009) in a different sample of tests, from the Minnesota Study of Twins Reared Apart (MISTRA). Our first hypothesis was that, given the greater diversity of the tests in MISTRA, the general-factor loadings would be less dependable than in Floyd et al. (2009). Our second hypothesis, contrary to the positions of Floyd et al. (2009) and Jensen and Weng (1994), was that the general factors from the small, randomly-formed test batteries would differ substantively from the general factor from a well-specified hierarchical model of all available tests. Subtests from MISTRA were randomly selected to form independent and overlapping batteries of 2, 4 and 8 tests in size, and the general-factor loadings of eight probe tests were obtained in each battery by principal components analysis, principal factor analysis and maximum likelihood estimation. Results initially indicated that the general-factor loadings were unexpectedly more dependable than in Floyd et al. (2009); however, further analysis revealed that this was due to the greater diversity of our probe tests. After adjustment for this difference in diversity, and consideration of the representativeness of our probe tests versus those of Floyd et al. (2009), our first hypothesis of lower dependability was confirmed in the overlapping batteries, but not the independent ones. To test the second hypothesis, we correlated g factor scores from the random test batteries with g factor scores from the VPR model; we also calculated special coefficients of congruence on the same relation. Consistent with our second hypothesis, the general factors from small non-hierarchical models were found to not be reliable enough for the purposes of theoretical research. We discuss appropriate standards for the construction and factor analysis of intelligence test batteries.     

Unraveling Cultural Threads: A Qualitative Study of Culture and Ethnic Identity Among Urban Southwestern American Indian Youth Parents and Elders

We utilized qualitative methods to explore ethnic and cultural identity among urban Southwestern American Indian youth, parents, and elders. Twenty-four respondents ranging in age from approximately 13 to 90 years were interviewed in focus groups divided by age. Six major themes and seventeen sub-themes related to tribal and pan-American Indian ethnic identity were identified. Two important findings emerging from our study were that common ethnic identity constructs can be validated and new identity constructs discovered through qualitative methods. These and other findings suggest the importance of qualitative methods in better understanding cultural and ethnic identity. Of particular significance was the notion that the most salient and relevant identity constructs can be learned from the voices and perspectives of ethnic identity members themselves across generations, age, tribal groups, gender, and reservation and urban residence.     

Being well at work: the impact of organizational climate and social identity on employee stress and self-esteem over time

In organizational psychology, staff perceptions of organizational climate have been found to be an important predictor of employee outcomes, such as employee stress. However, only a small pool of research has investigated the psychological mechanism that underpins the relationship, and no past literature has explored how the relationship persists over time. This paper uses the social identity approach to investigate whether social identification predicts and mediates the relationship between staff perceptions of organizational climate and their levels of stress and self-esteem over time. Employing a sample of public school teachers, the study was conducted over two years (N = 281, 65 schools). The results indicated that social identification fully mediated the relationship between organizational climate and self-esteem longitudinally but showed no significant relationship with stress. The implications of these findings are discussed, with recommendations for future research.     

Pretreatment Correlates of the Therapeutic Alliance in the Chronically Depressed

We examined the relationship between patient characteristics and the working alliance in a multisite trial for chronic depression. Patients treated with the Cognitive Behavioral Analysis System of Psychotherapy (CBASP), alone (n = 169) or combined with nefazodone (n = 198), completed the Working Alliance Inventory during the 2nd week of treatment. Within the CBASP alone group, a history of drug abuse/dependence, lower peak social adjustment over the past five years, and lower current social adjustment predicted a significantly poorer alliance. Within the combination group, male gender and a distancing coping style predicted a significantly poorer alliance. Results should be interpreted with caution since they did not replicate across treatment groups, and the number of significant findings were not much greater than chance expectations.
