The MMPI‐2 in chronic psychiatric illness

While previous studies on the MMPI‐2 in patients with schizophrenia and depression have used mixed samples of both early stage and chronic psychiatric patients. Here, it is investigated whether chronicity itself might have a differential effect on the MMPI‐2 profiles of these patients and whether demoralization ‘associated with long‐term illness’ affects the scales of the MMPI‐2. Thirty long‐term patients with schizophrenia, 30 long‐term patients with depression, and 30 healthy participants completed the MMPI‐2. Groups were compared on Clinical Scales and on the Restructured Clinical (RC) Scales. Patients with schizophrenia differed from patients with depression on 14 MMPI‐2 scales and from healthy controls on 10 scales, generally showing mean UT‐scores < 65, indicating a subjective experience of (near) normal functioning. Patients with depression differed from healthy controls on 17 scales mostly with UT‐scores > 65, indicating impaired functioning. Demoralization was higher in patients with depression than in patients with schizophrenia and both psychiatric groups differed from the healthy control group. It is concluded that long‐term patients with depression show impaired functioning and high demoralization, while long‐term patients with schizophrenia surprisingly show near normal functioning and less demoralization.

Ethical leadership,person-organizational fit,and productive energy: a South African sectoral comparative study

ABSTRACT

Research suggests that ethical leadership (EL) affects employee behavior and organizational functioning. This study aimed to determine the relationship between EL and productive energy (PE), as mediated by person-organizational fit (POF). The study used assumptions of the social learning and social exchange theories that posit that leadership has a direct impact on employee behavior, mainly through role modeling and the reciprocal nature thereof. An empirical paradigm using a cross sectional quantitative design was used. The PE instrument (developed in the USA) was assessed for construct validity within the South African context (exploratory and confirmatory factor analysis). The analysis included a comparison between the private and public sectors, emphasizing the importance of context as differentiator. Relatively high, statistically significant correlations were found between the variables for both sectors and the combined sample. The hierarchical regression analysis indicated that 18% of the variance in PE is explained by EL. This model was improved by the inclusion of POF (total variance of 32% explained). The conceptual model was confirmed with structural equation modeling (SEM). The findings of this study suggest that EL has a significantly positive effect on PE and POF, which mediates the relationship between EL and PE. Sectoral differences were reported.
