Dysfunction in affect regulation is a prominent feature that grossly impairs behavioural and interpersonal domains of experience and underlies a great deal of the psychopathology in borderline personality disorder (BPD). However, no study has yet been published that evaluates the psychometric properties of the translated Danish version of self-report measures sensitive to the different aspects and dimensions of dysfunction in affect regulation prevalent in BPD.
This study comprised a group of women diagnosed with BPD (n = 29) and a comparison group of healthy subjects (n = 29) who reported psychopathology and levels of affective instability, aggression, impulsivity and alexithymia by self-report measures.
Our results demonstrated that women with BPD have significant psychopathology and report significantly higher levels of dysfunction in separate components of affect regulation by self-report measures than the comparison group of healthy subjects. Our results also provided partial support for the psychometric appropriateness and clinical relevance of the translated Danish version of affect regulation measures.
The normative reference range indicated by our results makes the measures useful as a practical assessment tool.
The objective of this methodological pilot study was to make a contribution to the French-language validation of the Depressive Adjective Check List (DACL) Set 2 of Forms, E, F, G trait version (Lubin, 1981) and to that of the Multiple Affect Adjective Check List (MAACL-R; Zuckerman & Lubin, 1985). The importance of the study was to validate the French-language translation of these instruments to assess nonclinical depression or dysphoria and affect in two French- and English-speaking convenience sample groups. The Check Lists were administered to 183 Canadian subjects 60 years of age and over of both sexes from rural areas in the provinces of Quebec and Ontario, Canada. In order to ensure that the words chosen carried the same connotation as in the English language, a translation-retranslation technique was used. The data collected from this study suggest that the DACL Form G would be most valid to use with either language and/or site in the protocol for future studies.
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.
OBJECTIVE: The study investigated whether results on the Seasonal Pattern Assessment Questionnaire, which is used for diagnosis of seasonal affective disorder, differed by the season in which the questionnaire was completed. METHOD: Every third month from March 1997 to February 1998, a population-based panel of 200 men and women age 27-72 years in Gamvik, northern Norway, completed a standardized questionnaire that included all items from the Seasonal Pattern Assessment Questionnaire. RESULTS: The average score for seasonal affective disorder changed over the year. The difference between the highest score, in March, and the lowest, in September, was 8.8%. CONCLUSIONS: Results on the Seasonal Pattern Assessment Questionnaire varied by season, but did not vary by seasonal differences in the amount of daylight.
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.
The Basic Character Inventory (BCI) contains 136 items, 17 lower-order personality factors and three higher-order personality factors derived from psychoanalytic theory: Oral, Obsessive Compulsion, and Hysteria. Previous research that investigated the BCI's psychometric properties examined small, special populations and did not use modern statistical methods to validate the BCI. The present study validates the BCI via confirmatory factor analyses using a large sample of 6,285 Norwegian nursing and teaching students. Reliability, convergent validity, and divergent validity of the BCI were also assessed. Results indicated general support for the original BCI factor structure in a reduced form of the BCI that possesses strong reliability and validity, and is suitable for use in time-limited measurement settings.
