| The Nigerian-American Systemic Scales (NASAS), an acculturation scale, was standardized on first-generation Nigerian immigrants in America. The NASAS was specifically constructed to assess accultuartion patterns among Nigerians in the Diaspora. Two additional measures were revalidated on the sample. Adult Nigerian immigrants (N = 104) in California, New Jersey, Michigan, New York, Texas, and Massachusetts responded to four self-report instruments: a sociodemographics questionnaire, the Nigerian-American Systemic Scales (NASAS; Ndika, 2011), the Self-Efficacy Scale (SES; Sherer et al., 1982), and the Depression Anxiety Stress Scales 21 (DASS-21 Lovibond, S. H., & Lovibod, P. F., 1995). The components that emerged from the principal component analysis of the NASAS fit Berry's model of acculturation only modestly, and they accounted for 38.08% of the total variance in the instrument.;The components that emerged from principal component analysis of the SES and the DASS-21 failed to fit the underlying structures proposed by the original authors, respectively. Post hoc analyses provided information on the likely relationships between acculturation, depression, anxiety, normative stress, self-efficacy and sociodemographics data among the participants. The importance of the research findings, limitations of the study, and recommendations for further research were discussed. |
