The Ten-Item Personality Inventory (TIPI): a scoping review of versions, translations and psychometric properties.

Background: The Ten-Item Personality Inventory (TIPI) is a brief instrument designed to assess the five-factor model (FFM) personality dimensions. It was specifically developed to provide a brief assessment option in situations where using more comprehensive FFM instruments would be unfeasible. The TIPI enjoys widespread use and has been translated into several different languages. Objective: The aim of this scoping review was to generate an overview of different versions of the TIPI, and their psychometric properties in terms of two aspects of validity (convergent and structural) and two aspects of reliability (internal consistency and test-retest reliability). Methods: Four databases (PsycINFO, PubPsych, Medline, and Web of Science) were searched for studies exploring psychometric properties of the TIPI (original and/or translated or revised versions), published in English as full-text original research articles. Additionally, manual searches were conducted on the official TIPI website and in reference lists. Studies who utilized the TIPI simply as a measure, without an aim of testing its psychometric properties, were excluded. A descriptive-analytical approach was utilized to generate overviews of available TIPI versions and their psychometric properties. Results: In a total of 29 studies, 27 versions of the TIPI were identified, covering 18 different languages. Across versions, and evaluated against conventions of acceptable psychometric properties, the TIPI demonstrated acceptable test-retest reliability, somewhat mixed results for convergent and structural validity, and inappropriate internal consistency. Conclusion: Being a brief instrument, the TIPI is unsurprisingly characterized by certain psychometric shortcomings. However, the TIPI may represent a feasible compromise in instances where it is necessary to strike a balance between maximizing psychometric properties and minimizing survey length.

Working with alcohol prevention in occupational health services: "knowing how" is more important than "knowing that" - the WIRUS OHS study.

BACKGROUND: Alcohol consumption is a major public health challenge; the majority of employees consume alcohol regularly and a considerable proportion of employees can be characterized as risky drinkers in need of interventions. Occupational health services (OHS) are uniquely positioned for implementing alcohol prevention interventions targeting employees, but rarely do so. Studies have shown that lack of knowledge among OHS personnel is a barrier to alcohol prevention activity. This study aimed to explore OHS personnels' levels of theoretical and practical alcohol knowledge, and whether these two ways of knowing were differentially associated with alcohol prevention activity. METHODS: In this cross-sectional study, survey data were collected from 322 OHS personnel in Norway in 2018 (response rate = 53.6%). The survey included variables of two ways of knowing (theoretical and practical) and three types of doing (intervention frequency, conducting individual interventions, and conducting group interventions). Data were analyzed with descriptive statistics, paired sample t-tests, bivariate correlations, and adjusted linear and logistic regression analyses. RESULTS: OHS personnel rated their theoretical alcohol knowledge higher than their practical knowledge (η2 = 0.33, p < 0.001). Higher reported levels of practical knowledge were associated with higher intervention frequency (b = 0.39, ß = 0.60, p < 0.001) and greater likelihood of conducting individual interventions (OR = 1.60, p < .001) as well as group interventions (OR = 1.84, p < 0.001). Theoretical knowledge was not associated with conducting interventions, and there was no evidence of an interaction between the two ways of knowing in their association with doing. Sensitivity analyses did not indicate clustering effects of OHS personnel being employed within different units. CONCLUSIONS: Different ways of knowing about alcohol among OHS personnel were dissimilarly associated with conducting alcohol prevention interventions in occupational health settings. For doing, knowing how seems to be more important than knowing that. Training programs for OHS personnel should emphasize knowledge about how to deal with alcohol-related issues and how to conduct prevention interventions, rather than focus on detrimental effects of alcohol.

Internal Consistency and Structural Validity of the Norwegian Translation of the Ten-Item Personality Inventory.

Background: The Ten-Item Personality Inventory (TIPI) is a validated brief instrument measuring the five-factor model (FFM) personality dimensions, developed for instances where more comprehensive FFM instruments are impractical to use. The TIPI has been translated into several languages, but psychometric properties of the Norwegian version (N-TIPI) have not been systematically explored. Objectives: This study aimed to explore the psychometric properties of the N-TIPI, in terms of internal consistency and structural validity. Methods: In a cross-sectional study, responses on the N-TIPI were collected from 5,009 Norwegian master graduates. Descriptive statistics for the subscales and correlations between subscales were calculated. Internal consistency was assessed with inter-item correlations, Cronbach's α and Spearman-Brown coefficients. Structural validity was explored with principal component analysis, parallel analysis, and visual scree plot inspection. Results for the N-TIPI were compared with those previously reported for the original TIPI as well as the German, French, Spanish, and Portuguese versions. Results: Compared with the original and non-English versions of TIPI, results for N-TIPI showed comparable subscale rank order of means, standard deviations, and pattern of correlations between subscales, as well as inter-item correlations and Cronbach's α. The 10 N-TIPI items were adequately reduced to five components, theoretically corresponding with the FFM personality domains. Conclusion: The N-TIPI demonstrated acceptable internal consistency and satisfactory structural validity. Although further research is warranted, the instrument stands out as feasible when it is essential to minimize participants' response burden in studies that aim to explore personality as one among several concepts or utilize personality traits as covariates.
