construct validity and factor structure of a Spanish Language social support questionnaire during early pregnancy
International Journal of Women's Health, 2018Co-Authors: Lauren E Friedman, Ana Karen Manriquez Prado, Gabriel Fidel Santos Malave, Juan Carlos Q Velez, Rodrigo Winston Gillibrand Esquinazi, Sixto E Sanchez, Qiuyue Zhong, Bizu Gelaye, Michelle A WilliamsAbstract:Background: The Social Support Questionnaire - Short Form (SSQ-6) is a widely used instrument that assesses availability and satisfaction of a person's social support. The present study aimed to evaluate the construct validity and factor structure of the Spanish Language version of the SSQ-6 during early pregnancy. Participants and methods: A total of 4,236 pregnant Peruvian women were interviewed at 10.3 ± 3.8 weeks of gestation. In-person interviewers were used to collect lifestyle, demographic, and social support characteristics. The construct validity and factorial structure of the SSQ-6 were assessed through exploratory factor analysis (EFA) and confirmatory factor analysis (CFA). The internal consistency was evaluated using Cronbach's alpha. Results: The mean SSQ-6 score was 39.6 ± 6.8 and Cronbach's alpha was 0.83. EFA resulted in a three-factor solution that accounted for 60.6% of the variance. CFA results confirmed the three-factor structure and yielded measures indicating goodness of fit (comparative fit index of 0.9401) and accuracy (root mean square error of approximation of 0.0394). Conclusion: Although the SSQ-6 was originally developed as a two-factor model, and previous studies have supported this, in our study a three-factor model was found to be more appropriate. The SSQ-6 was found to have good construct validity and reliability for assessing social support.

cross cultural validity of the Spanish version of phq 9 among pregnant peruvian women a rasch item response theory analysis
Journal of Affective Disorders, 2014Co-Authors: Qiuyue Zhong, Sixto E Sanchez, Bizu Gelaye, Jesse R Fann, Michelle A WilliamsAbstract:Abstract Objective We sought to evaluate the validity of the Spanish Language version of the patient health questionnaire-9 (PHQ-9) depression scale in a large sample of pregnant Peruvian women using Rasch item response theory (IRT) approaches. We further sought to examine the appropriateness of the response formats, reliability and potential differential item functioning (DIF) by maternal age, educational attainment and employment status. Methods This cross-sectional study was conducted among 1520 pregnant women in Lima, Peru. A structured interview was used to collect information on demographic characteristics and PHQ-9 items. Data from the PHQ-9 were fitted to the Rasch IRT model and tested for appropriate category ordering, the assumptions of unidimensionality and local independence, item fit, reliability and presence of DIF. Results The Spanish Language version of PHQ-9 demonstrated unidimensionality, local independence, and acceptable fit for the Rasch IRT model. However, we detected disordered response categories for the original four response categories. After collapsing “more than half the days” and “nearly every day”, the response categories ordered properly and the PHQ-9 fit the Rasch IRT model. The PHQ-9 had moderate internal consistency (person separation index, PSI=0.72). Additionally, the items of PHQ-9 were free of DIF with regard to age, educational attainment, and employment status. Conclusions The Spanish Language version of the PHQ-9 was shown to have item properties of an effective screening instrument. Collapsing rating scale categories and reconstructing three-point Likert scale for all items improved the fit of the instrument. Future studies are warranted to establish new cutoff scores and criterion validity of the three-point Likert scale response options for the Spanish Language version of the PHQ-9.

impact of Spanish Language information sessions on Spanish speaking patients seeking bariatric surgery
Surgery for Obesity and Related Diseases, 2017Co-Authors: Allison Martin, Miguel Marino, Marie Killerby, Liliana Rossellirisal, Kellene Isom, Malcolm K RobinsonAbstract:Abstract Background Bariatric centers frequently provide preoperative educational programs to inform patients about the risks and benefits of weight loss surgery. However, most programs are conducted in English, which may create barriers to effective treatment and access to care for non-English speaking populations. To address this concern, we instituted a comprehensive Spanish-Language education program consisting of preoperative information and group nutrition classes conducted entirely in, and supported with Spanish-Language materials. Objectives The primary aim was to examine the effect of this intervention on Spanish-speaking patients' decision to undergo surgery in a pilot study. Setting University Hospital/Community Health Center, United States. Methods Three cohorts of patients seeking bariatric surgery between January 1, 2011 and March 31, 2012 were identified: 1) primary English speakers attending English-Language programs ("English-English"); 2) primary Spanish speakers attending Spanish-Language programs ("Spanish-Spanish"); and 3) primary Spanish speakers attending English-speaking programs with the assistance of a Spanish-to-English translator ("Spanish-English"). Results 26% of the English-English cohort ultimately underwent surgery compared with only 12% of the Spanish-Spanish cohort ( P = .009). Compared with the English-English group, time to surgery was 35 days longer for the Spanish-Spanish and 185 days longer for the Spanish-English group (both P .001). Conclusion Spanish-speaking patients were less likely to undergo bariatric surgery regardless of the Language in which educational sessions are provided. For those choosing surgery, providing Spanish-Language sessions can shorten time to surgery. A barrier to effective obesity treatment may exist for Spanish speakers, which may be only partially overcome by providing support in Spanish.

The Latino/a audience unbound: Intra-ethnic social hierarchies and Spanish-Language television news
Latino Studies, 2018Co-Authors: Sallie HughesAbstract:Many US Spanish-Language television producers, marketers and academics construct Latino/a identity in Spanish-Language media narrowly, despite numerous scholarly critiques of the pan-Latino label. Examining how Latino/a immigrants in metropolitan Miami interpret representations of immigrants, immigrant communities, and urban services in Spanish-Language news, I argue that diverse Latino/a audiences emerge according to how the media representations evoke participants’ subjective positioning in locally and nationally embedded social hierarchies. The study reveals how intra-Latino/a factors affect audience formation, and discusses implications for audience studies and journalism practice.
