Psychometric evaluation and normative data for a Swedish version of the Patient Health Questionnaire 15‐Item Somatic Symptom Severity Scale

The lack of an available Swedish version of the Patient Health Questionnaire 15‐Item Somatic Symptom Severity Scale (PHQ‐15) motivated the present psychometric evaluation of such a version as well as providing normative data for the PHQ‐15. Data from 3,406 individuals who took part in the Västerbotten Environmental Health Study in Sweden were used. The respondents constitute a random sample, aged 18 to 79 years, stratified for age and sex. They responded to a Swedish translation of the PHQ‐15 as well as the Hospital Anxiety and Depression Scale, the Perceived Stress Scale, and the Shirom Melamed Burnout Questionnaire for assessment of convergent validity. The distribution of PHQ‐15 scores was positively skewed and mesokurtic in shape, and the internal consistency of the PHQ‐15 was satisfactory. Correlation coefficients between PHQ‐15 score and the measures of anxiety, depression, stress and mental/physical exhaustion indicate satisfactory validity. Normative data for PHQ‐15 scores as well as for categories of somatic symptom severity are provided. The favorable psychometric properties of the Swedish version of the PHQ‐15 suggest use of this instrument for quantification of somatization in Swedish and similar populations, and has the advantage of available normative data.     

Action Assembly Theory and Communication Apprehension A Psycho-physiological Study

Research reported here replicates Greene and Sparks (1983a, 1983b) and their re-conceptualization of communication apprehension (CA). Noting the limited empirical evidence in support of a trait/structure link with physiological output, this study applies action assembly theory to the problem. Differential heart rate curves are predicted for high and low trait CA based on Greene's (1984) action assembly theory. The study confirms a hypothesized cubic heart rate function for low trait CA subjects and a quadratic heart rate function for high trait CA subjects. Results are interpreted as empirical support for an action assembly approach to communication anxiety.     

Hanly on Coase: A Comment

ABSTRACT Ken Hanly's recent article in this Journal (Vol. 9, No. 1, 1992) takes issue with Ronald Coase's approach to resolving problems of externalities, as set forth in his classic paper 'The Problem of Social Cost'. I argue that Hanly's discussion of Coase misinterprets or inappropriately rejects certain aspects of Coase's analysis, specifically, with regard to the reciprocal nature of externalities and the economic role of government. The resolution of externality problems is presented as an issue of selective normative choice as to whose interests are to count; neither efficiency nor morality claims are uniquely dispositive of the issue.

Men's sociosexuality is sensitive to changes in mate availability

Correlational research has linked mate availability to human sexual behavior, whereby unrestricted sociosexuality seems to be most common under conditions of female abundance. In this study, 71 heterosexual men were randomly assigned to one of two mate availability priming conditions, mate scarcity or mate abundance, and subsequently completed measures of sociosexuality as well as infidelity intentions. Results indicated that men in the mate abundance condition reported stronger sociosexual attitudes and desires, and among those currently in relationships, stronger infidelity intentions. These findings were contrasted with those from a separate sample of 66 heterosexual undergraduate women. Mate scarcity had no effects on women's sociosexuality or infidelity intentions. Findings suggest that when mates are scarce, men will adopt a sociosexual orientation aimed at maintaining a single partner.
