The Factor Structure of the Brief Symptom Inventory-18 With Latino Immigrant Day Laborers
Methods: Participants (N=150) were recruited from day labor sites in a large southwestern city as part of a larger study on the well-being of Latino migrant day laborers. To be eligible to participate in the study, participants had to be Latino, male, aged 18 or older, and currently working as a day laborer.
Results: A series of principal axis exploratory factor analytic procedures examining one to three-factor models were performed. The Kaiser-Meyer-Olkin (KMO) measure of sampling adequacy value was .85, and the Bartlett’s Test of Sphericity was significant, χ = 838.26 (df = 15.), p <.001, which indicated that factorability of the data was good. A one-factor model emerged and four items were dropped due to low factor loadings. The single factor appeared to reflect general somatic-psychological distress, and the three strongest loadings included fearful (.71), depressed (.709), and nervousness (.65). The internal consistency coefficients for the 14-item BSI were α = .87. These findings are aligned with previous findings with low-income Latina mothers (Prelow et al, 2005), and suggest that in contrast to the original three dimension structure, the BSI-18 appears to measure a single dimension of general somatic-psychological distress in this sample of LDLs.
Implications: Researchers are recommended to use the BSI-18 as a general measure of psychological distress with LDLs. Findings have implications for elucidating the prevalence of psychological distress among LDLs as well as advancing the research on the mental health of this population.
