The Identification With All Humanity (IWAH) scale: its psychometric properties and associations with help-seeking during COVID-19

The Identification With All Humanity (IWAH) scale was designed to measure the extent to which an individual identifies oneself with all human beings. The current research aimed to conduct the validation of IWAH in a Chinese population and its convergent validity, as well as test the implications of IWAH in associations with help-seeking behaviour during COVID-19. A serial of three studies was conducted from September 1st 2020 to the end of October 2020. The series of studies included Study 1- Exploring the dimensions of the IWAH scale with a sample of 2,881 participants, Study 2- Confirmatory Factor Analysis for the Chinese IWAH dimensions with a separate sample of 6,667 participants, and Study 3- Role of the IWAH in the COVID-19 pandemic with a sample of 9,046 participants. Study 1 found the Chinese version of the IWAH scale to be a two-dimensional construct, with factor 1 - Bond with Humanity and factor 2 - Human Kinship. Study 2 confirmed the two-factor construct as found in Study 1. It also showed positive relations between IWAH and moral judgement, collectivism, nature connectedness, and negative relations with callousness, and having anxiety and depressive symptoms. Study 3 found that IWAH was negatively related to fear of COVID-19 and positively related to the likeliness of help-seeking. This is the first research to test the factorial structure of the IWAH scale in a Chinese population, with the adaptation showing good psychometric properties. The implication of IWAH on fear of COVID-19 and help-seeking provided further understanding of the possible practical value of IWAH during times of global stressful life events. Furthermore, study 3 is the first to explore how IWAH relates to anxiety, depression, and callousness.
