Validity and reliability of electroencephalographic frontal alpha asymmetry and frontal midline theta as biomarkers for depression

Electroencephalographic (EEG) frontal alpha asymmetry (FAA) and frontal midline (FM) theta have been suggested as biomarkers for depression and anxiety, but have mostly been assessed in small and non‐clinical studies. In a clinical sample of 79 adults with depression (ICD‐10: F32), resting EEG and scales of depression (MADRS) and anxiety (HADS‐A) were measured at intake and after 3 months. FAA and FM theta values were referenced to a normative population database. Internal consistency, test‐retest reliability, and correlations with psychiatric tests were examined. Reliability was sufficient. However, FAA and FM theta values were close to the general population, and correlations with psychiatric tests were mostly small and non‐significant, with the exception of FAA on F7–F8 z‐scores and HADS‐A. We conclude that the validity of FAA and FM theta and therefore their potential as biomarkers for depression and anxiety remain unclear.     

The Meanings of the Community and of the Individual in Slovakia and in Scotland

The purpose of this paper was to examine meanings of the terms ‘individual’, ‘the community’ and ‘local community’ in Slovakia and Scotland. The social, cultural, political and economic histories of these two small European nations are quite different. Slovakia is one of the post-communist countries in which rapid changes have recently taken place. In contrast, Scotland has enjoyed a relatively stable parliamentary democracy within the UK. Two groups of respondents, 200 from Slovakia and 200 from Scotland, were presented with a word association task which included 38 political and economic terms and with two scales containing the same list of terms. They rated phenomena referring to these terms with respect to their importance for the well-being of the individual and to the well-being of the community. The results suggest that for Scots but not for Slovaks, the term ‘local community’ evokes positive associations and that local community is a meaningful concept. The data suggest that local attachments and loyalties were destroyed in Slovakia during communism. (© 1997 by John Wiley & Sons, Ltd.)     

Couples Therapy Using the Technique of Construct Differentiation

A central problem in couples therapy is the clients' tendency to persist in endless and fruitless alternation between attacking the partner and justifying themselves. The technique of construct differentiation described in this article has proved helpful in coping with this situation. In three clearly structured steps, the therapist explores the personal constructs of each partner in the presence of the other. Instead of concentrating in the usual way on circularity of thoughts, feelings, and behavior, the partners are hindered from interacting and are confronted by the therapist's questions concerning their own inner process, independently of that of the partner. By becoming aware of their own ambivalent constructs and those of the partner, the eagerness to convert the partner to their own point of view can be reduced, and the construct system of each partner can be enriched by the other's constructs. Construct differentiation proves especially useful in the treatment of power struggles and narcissistic collusions.     

Influences of Organizational Culture and Climate on Individual Creativity

This paper provides a framework for conceptualizing and reviewing the literature on the influences of organizational culture and climate on individual creativity. Although often treated interchangeably, culture and climate are distinct constructs operating at different levels of meaning; yet at the same time, they are closely interrelated. Culture is the beliefs and values held by management and communicated to employees through norms, stories, socialization processes, and observations of managerial responses to critical events. The beliefs and values that typify a culture for creativity become manifested in organizational structures, practices, and policies. In turn, these structures, practices, and policies guide and shape individual creativity by creating a climate that communicates both the organization's goals regarding creativity and the means to achieve those goals. The paper concludes with a discussion of issues relating to the development of cultures and climates for creativity and potential new directions for future research.
