Computing Cohen’s kappa coefficients using SPSS MATRIX

This short paper proposes a general computing strategy to compute Kappa coefficients using the SPSS MATRIX routine. The method is based on the following rationale. If the contingency table is considered as a square matrix, then the observed proportions of agreement lie in the main diagonal’s cells, and their sum equals the trace of the matrix, whereas the proportions of agreement expected by chance are the joint product of marginals. The generalization to weighted kappa, which requires an additional square matrix of disagreement weights, both matrices having the same order, becomes possible by the use of the Hadamard product-that is, the elementwise direct product of two matrices.     

Correlates of gender role orientation during pregnancy and the postpartum

This study was designed to examine the relationship between gender role orientation and psychological adjustment during pregnancy and the postpartum period in a large sample of French-speaking Caucasian mothers. Gender role was assessed with the Bem Sex Role Inventory, which classifies subjects into four categories: androgynous, masculine, feminine, and undifferentiated. A discriminant analysis showed a relationship between androgyny and the following measures of psychological adaptation: self-esteem, satisfaction with social support, and level of apprehension toward perinatal stressors. The masculine gender role was linked with self-esteem, work involvement, age, and severity of perinatal stress. No relationship was found between gender role and the level of antenatal or postnatal depressive symptomatology. Stress, marital support, and social support were among the predictors of postpartum depression, which underlined the importance of taking these variables into account when studying the well-being of mothers during the postnatal period. Results are discussed in light of previous literature on the association between gender role and motherhood. The limitations of Bem's model and inventory are also considered.     

Listening to speech while retaining music: What happens to the right-ear advantage?

On each trial, subjects were played a dichotic pair of syllables differing in the consonant (/ba/, /da/, /ga/) or in the vowel (/ba/, /b?/, /bi/). The pair of syllables was preceded by a melody, or a sentence, and followed by the same or a different melody, or sentence. Subjects either had to retain the first piece of additional material or were free to ignore it. The different combinations of phonemic contrast, additional material, and instruction concerning the additional material were used in different sessions. In each case, the main task of the subjects was to respond to the presence or the absence of the target /ba/ on the ear previously indicated. There was no effect of context on relative ear accuracy, but the right-ear advantage observed for consonants in response latency when subjects retained a sentence gave way to a small nonsignificant left-ear advantage when subjects retained a melody. Right-ear advantage in response latencies was also observed for vowels in the verbal context, but the contextual effect, although in the same direction as for consonants, was very slight. The implications of contextual effects for a theory of the determinants of the auditory laterality effects are discussed.

Possession and Applicability of Signature Character Strengths: What Is Essential for Well-Being,Work Engagement,and Burnout?

Signature character strengths can foster health-related outcomes in work and private life, thus being particularly important for endangered occupational groups like physicians. However, situational circumstances need to allow character strengths demonstration (applicability) first to enable their application. Therefore, this study addresses the role of (1) applicability of signature character strengths in work and private life beyond their possession and (2) relationships with well-being, work engagement, and burnout dimensions (emotional exhaustion, depersonalization, and reduced personal accomplishment). Hospital physicians (N = 274) completed an online survey examining their signature character strengths and applicability, well-being, work engagement, and burnout dimensions. The top-five individual signature character strengths were fairness, honesty, judgment, kindness, and love. Hierarchical multiple linear regressions revealed that the possession as well as the applicability of signature character strengths was important in work and private life, but to different degrees. Possessing fairness, honesty, or kindness indicated significant positive relations with subjective well-being, whereas judgment and kindness seemed to negatively interact with reduced personal accomplishment. Hospital physicians’ applicability of fairness, honesty, judgment, and love was particularly essential for their psychological well-being and work engagement, whereas the applicability of fairness (reduced personal accomplishment) and judgment (emotional exhaustion, depersonalization) at work interacted negatively with the respective outcomes. Therefore, creating awareness for individual signature character strengths as well as providing applicability in hospitals and private life could be a promising approach to improve physicians’ well-being and consequently patient care as well as the performance of the health-care system in general.
