“…The hygiology model is based on an integration of theory and research common to counseling psychology, including models of racial and ethnic identity development, the tolerant personality, the universal-diverse orientation, gay and lesbian identity models, and indigenous psychology and spirituality (see Ponterotto, 2010 for details). This theoretical model has been operationalized by the Multicultural Personality Inventory (MPI, 70 items; Ponterotto et al, 2014) and its short form (MPI-SF, 42 items; Fietzer et al, 2019), which have identified seven factors that can be used as subscales: Racial and Ethnic Identity Development (RID), Social Justice Activism (SJA), Psychological Health (PH), Connectedness and Spirituality (CS), Humor (HUM), Opposite Gender and Sexual Orientation Connection (OGC), and Culturally Diverse Friendships (CDF). The MPI is associated with cultural adaptation and altruistic behavior (Fietzer et al, 2016; Fietzer et al, 2019; Ponterotto et al, 2014), authentic living (Reynolds et al, 2019), counselor cultural competence (Fietzer et al, 2018), and pro-social attitudes (Korol et al, 2018) beyond broad measures of personality such as the Big Five.…”
