The Polish version of the Cultural Intelligence Scale: Assessment of its reliability and validity among healthcare professionals and medical faculty students

Abstract

BackgroundHealthcare professionals and students of medical faculties in Poland increasingly encounter culturally diverse patients. It is necessary to support the development of cultural intelligence in order to improve the medical care provided to patients from different cultural backgrounds. At present there are no standardized tools in Poland that can accurately and reliably assess cultural intelligence, which is defined by Ang et al. as “an individual’s capability to function and manage effectively in culturally diverse settings”. As argued in the present paper, this (cap)ability may be important for providing patient-centred care that is culturally adequate and competent.PurposeThe aim of the research was to show the multistage process of validation of the Polish version of The Cultural Intelligence Scale by Ang et al. and Van Dyne et. al.MethodsAcross two studies we examined the psychometric properties of the Cultural Intelligence Scale, including reliability (i.e. internal consistency, test-retest reliability, factor structure) and validity (i.e. theoretical, criteria, convergent). In the first two-session study, 349 participants (98% were healthcare professionals, e.g. nurse, student nurse, medical student; mainly women, 89%) completed the Polish version of the Cultural Intelligence Scale twice with an interval of at least 22 days. In addition, across two study sessions participants completed questionnaires constructed to measure (a) cultural competence, (b) need for cognitive closure, (c) emphatic sensitiveness, (d) emotional intelligence, (e) self-esteem, (f) social desirability, (g) personality, and (h) positive/negative attitudes towards culturally divergent people. Finally, to additionally examine the theoretical validity, 36 professional cross-cultural competence trainers completed the Cultural Intelligence Scale during a one-session study.ResultsThe Cultural Intelligence Scale has been shown to have satisfactory psychometric properties. It has high reliability (Cronbach’s alpha, respectively .94 and .95 in the first and second sessions) and the factor structure seems to approach the postulated one. Theoretical and criterion accuracy are well proven; convergence is less straightforward, but it correlates well with tools that examine variables such as cultural competence, cognitive closure, empathy/emphatic sensitiveness, emotional intelligence, self-esteem, personality, and social desirability. The results suggest that these factors contribute to the development of the cultural intelligence.ConclusionThe Cultural Intelligence Scale can be successfully used in empirical research of cultural intelligence of medical professionals and students of medical majors and their education in Polish conditions.

The relationship between personality, self-esteem, emotional intelligence, and cultural intelligence. A military context

“…Study 5 showed that self-esteem is only related to motivational CQ. Similar conclusions are presented by Barzykowski et al (2019), although in this case, there are also no previous studies with which to make comparisons.…”

“…Their knowledge can result both from experience as well as from directed cognitive activity. Such individuals also display an aboveaverage ability to direct their attention and energy towards knowing and understanding multicultural situations (Barzykowski, Majda, Szkup, & Przyłęcki, 2019).…”

“…Study 4 points towards a relationship between CQ and emotional intelligence (Barzykowski et al, 2019;Daryani, Aali, Amini, & Shareghi, 2017;Jonck & Swanepoel, 2015). Moon (2010) claims that specific factors of emotional intelligence are related to specific factors of CQ.…”

Self‐Reported Cultural Competence of Nurses Providing Nursing Care in Slovakia

“…Social desirability bias associated with self‐report questionnaires may have influenced results despite the anonymous nature of our survey. While two thirds of respondents felt competent or very competent, the actual proportion may be smaller (Barzykowski, Majda, Szkup & Przyłęcki, 2019). Additionally, the Cronbach’s alpha score obtained on the translated version was not as high as expected.…”

Nurse Cultural Competence-cultural adaptation and validation of the Polish version of the Nurse Cultural Competence Scale and preliminary research results

“…Currently, for the purposes of testing cultural competence of the Polish nursing community, several scales have been adapted, i.e. the Cultural Intelligence Scale (CQS) by Ang, Van Dyne and Koh, which makes it possible to estimate cultural intelligence, that is to say, the individual's ability to deal effectively in situations of cultural diversity [20,21]. This same team has adapted and assessed the psychometric values of The Cross-Cultural Competence Inventory, permitting an evaluation of the seven dimensions of intercultural competence, i.e.…”
