Abstract summary
Despite the last decade's significant development in the scientific study of work addiction/workaholism, this area of research is still facing a fundamental challenge, namely the need for a valid and reliable measurement tool that shows cross-cultural invariance and, as such, allows for worldwide studies on this phenomenon.An initial 16-item questionnaire, developed within an addiction framework, was administered alongside job stress, job satisfaction, and self-esteem measures in a total sample of 31,352 employees from six continents and 85 cultures (63.5% females, mean age of 39.24 years).Based on theoretical premises and psychometric testing, the International Work Addiction Scale (IWAS) was developed as a short measure representing essential features of work addiction. The seven-item version (IWAS-7), covering all seven components of work addiction, showed partial scalar invariance across 81 cultures, while the five-item version (IWAS-5) showed it across all 85 cultures. Higher levels of work addiction on both versions were associated with higher job stress, lower job satisfaction, and lower self-esteem across cultures. The optimal cut-offs for the IWAS-7 (24 points) and IWAS-5 (18 points) were established with an overall accuracy of 96% for both versions.The IWAS is a valid, reliable, and short screening scale that can be used in different cultures and languages, providing comparative and generalizable results. The scale can be used globally in clinical and organizational settings, with the IWAS-5 being recommended for most practical and clinical situations. This is the first study to provide data supporting the hypothesis that work addiction is a universal phenomenon worldwide.Authors & Co-authors: Charzyńska Edyta E Buźniak Aleksandra A Czerwiński Stanisław K SK Woropay-Hordziejewicz Natalia N Schneider Zuzanna Z Aavik Toivo T Adamowic Mladen M Adams Byron G BG Al-Mahjoob Sami M SM Almoshawah Saad A S SAS Arrowsmith Jim J Asatsa Stephen S Austin Stéphanie S Aziz Shahnaz S Bakker Arnold B AB Balducci Cristian C Barros Eduardo E Bălțătescu Sergiu S Bdier Dana D Bhatia Nitesh N Bilic Snezana S Boer Diana D Caspi Avner A Chaleeraktrakoon Trawin T Chan Connie I M CIM Chien Chung-Jen CJ Choi Hoon-Seok HS Choubisa Rajneesh R Clark Marilyn M Čekrlija ĐorĐe Đ Demetrovics Zsolt Z Dervishi Eglantina E de Zoysa Piyanjali P Domínguez Espinosa Alejandra Del Carmen ADC Dragova-Koleva Sonya S Efstathiou Vasiliki V Fernandez Maria Eugenia ME Fernet Claude C Gadelrab Hesham F HF Gamsakhurdia Vladimer V Garðarsdóttir Ragna Benedikta RB Garrido Luis Eduardo LE Gillet Nicolas N Gonçalves Sónia P SP Griffiths Mark D MD Hakobyan Naira Rafik NR Halim Fatimah Wati FW Hansenne Michel M Hasan Bashar Banwan BB Herttalampi Mari M Hlatywayo Clifford K CK Hromatko Ivana I Igou Eric Raymond ER Iliško Dzintra D Isayeva Ulker U Ismail Hussein Nabil HN Jensen Dorthe Høj DH Kakupa Paul P Kamble Shanmukh S Kerriche Ahmed A Kubicek Bettina B Kugbey Nuworza N Kun Bernadette B Lee J Hannah JH Lisá Elena E Lisun Yanina Y Lupano Perugini María Laura ML Marcatto Francesco F Maslovarić Biljana B Massoudi Koorosh K McFarlane Tracy A TA Mgaiwa Samson John SJ Moosavi Jahanabad Seyyed Taha ST Moreta-Herrera Rodrigo R Nguyen Hang Thi Minh HTM Ohtsubo Yohsuke Y Özsoy Tuğba T Øvergård Kjell Ivar KI Pallesen Ståle S Parker Jane J Plohl Nejc N Pontes Halley M HM Potter Rachael R Roe Alan A Samekin Adil A Schulmeyer Marion K MK Seisembekov Telman Z TZ Serrano-Fernández María José MJ Shahrour Ghada G Matić Jelena Sladojević JS Sobhie Rosita R Spagnoli Paola P Story Joana J Sullman Mark J M MJM Sultanova Liliya L Sun Ruimei R Suryani Angela Oktavia AO Sussman Steve S Teng-Calleja Mendiola M Torales Julio J Vera Cruz Germano G Wu Anise M S AMS Yang Xue X Zabrodska Katerina K Ziedelis Arunas A Atroszko Paweł A PA
