Internationally, the NEO Personality Inventory-Revised (NEO-PI-R) is a well established questionnaire for assessment of personality in accordance with the Five Factor Model. The instrument has been translated into many languages including Swedish.
The aim of this study was to make a psychometric evaluation of the Swedish version of NEO-PI-R based on a sample from the general population.
Postal questionnaires were sent to a random sample of 1250 persons (n = 766 responders).
The test showed satisfactory internal consistency in the broad factors as well as the facets. A factor analysis indicated that the factors were similar but not identical to those obtained in American studies. In sum, The Swedish version of the NEO-PI-R shows satisfactory psychometric properties and the instrument will continue to be a valuable tool in psychological research and in clinical practice.
To estimate the validity and reliability of the Leadership and Management Inventory, a tool to measure the skills and abilities of first-line nurse managers.
The decision to develop an inventory reflects the need for an instrument that can measure the various skills and abilities first-line nurse managers should possess.
Factor analysis was conducted and internal consistency initially estimated on data from 149 registered nurses; a second sample of 197 health care personnel was used to test these results.
Principal component analysis of the first sample resulted in a preferred three-factor solution that explained 65.8% of the variance; Cronbach's alpha coefficient varied between 0.90 and 0.95. Analysis of the second sample also resulted in a three-factor solution that explained 64.2% of the variance; Cronbach's alpha coefficient varied from 0.88 to 0.96. For both samples, the factors were labelled 'interpersonal skills and group management', 'achievement orientation' and 'overall organizational view and political savvy'.
Results indicate that estimates of validity and reliability for the Leadership and Management Inventory can be considered acceptable.
The Leadership and Management Inventory can be used when first-line nurse managers' leadership and management skills and abilities are to be measured.
Depressive personality is commonly seen in clinical practice, and today only one exclusive self-report instrument-the Depressive Personality Disorder Inventory (DPDI)-is available for its assessment based on the DSM-IV description of the construct.
The purpose of this research was to evaluate a Swedish version of this measure (DPDI-Swe) in terms of its reliability, internal structure, and convergent validity using related variables from the DSM-IV criteria for depressive personality disorder (DPD) and the proposed DPD trait set for DSM-5.
A non-clinical sample of 255 adults in southern Sweden completed a self-report package, which, in addition to DPD, included the assessment of self-esteem, optimism, hope, rumination, worry, depression, and anxiety. Quality of life was also measured.
Results indicated that the DPDI-Swe was internally consistent (a = 0.96). Exploratory factor analysis with oblique rotation yielded three components, together accounting for 48.21% of the variance in DPDI-Swe scores. There were strong positive associations between the DPDI-Swe and measures of depression, anxiety, rumination, and worry, and strong negative associations between the DPDI-Swe and measures of self-esteem, optimism, hope, and quality of life. These significant relationships remained, albeit slightly diminished, after statistically controlling for current depressed mood.
The DPDI-Swe appears to be a reliable and valid measure of DPD, and it is available for clinical and research use.
The Temperament and Character Inventory (TCI) is a self-report personality questionnaire based on Cloninger's psychobiological model of personality, which accounts for both normal and abnormal variation in the two major components of personality, temperament and character. Normative data for the Swedish TCI based on a representative Swedish sample of 1,300 adults are presented, and the psychometric properties of the questionnaire are discussed. The structure of the Swedish version replicates the American version well for the means, distribution of scores, and relationships within the between scales and subscales. Further, the Swedish inventory had a reliable factor structure and test-retest performance. The results of this study confirm the theory of temperament and character as a seven-factor model of personality.
