Objectives. While valid assessment of subjective well-being (SWB) is at the forefront of ageing research, literature increasingly reports cross-cultural measurement invariance on scales designed to capture SWB. This study examines measurement properties of well-established SWB scales and their comparability between older Hispanics and Whites in the US. Methods. We examined measurement properties of the satisfaction with life (SWL), purpose in life (PIL)and positive affect (PAF) scales using multigroup confirmatory factor analysis (CFA) and multigroup hierarchical CFA on three subgroups in the Health and Retirement Study: non-Hispanic Whites, Hispanics interviewed in English and Hispanics interviewed in Spanish. We also examined acquiescence response style in measurement invariance testing. Results. SWL was the only scale that provided reasonable measurement invariance. However, it lacked comparability in its measurement validity, with much lower validity for Hispanics than Whites. Measurement invariance was observed lower across all models when fitted on the data restricted to respondents with a tendency to acquiesce than the counterpart. Discussion. Our analysis offers evidence that the traditional measurement invariance test is not effective under the presence of response style for measurement instruments that use the Likert-type response scales. Research into cross-cultural differences in conceptualization of SWB and methodology to measure SWB is likely to improve our ability to accurately understand SWB with the increasingly diverse population.

Objectives: Nativity and family support may influence attitudes and behaviors that delay or accelerate the disability process in older adults. The objectives of this study were twofold: 1) to evaluate nativity and migration cohort differences in trajecto­ries of disability (assessed by activities of daily living [ADL]) among older Mexican Americans; and 2) to determine the role of objectively measured family support in the association between nativity, migration cohort, and disability changes over time.Methods: This is a longitudinal study with up to 18 years follow-up (1993-2011) using data from the Hispanic Established Populations for the Epidemiologic Study of the Elderly (N=2,785, mean age =72.4 years). Disability was assessed using self-reported limitations in activities of daily living (ADL). Nativity and migration cohort were self-reported. Family support was as­sessed by marital status and the number of their children participants saw each month. Linear growth curve models evaluated the trajectory of ADL disability over 18 years and assessed variations by nativity status, migration cohort and family support.Results: Foreign-born respondents who migrated before age 20 had more starting ADL limitations (β= .36, P<.001) and ac­cumulated disability faster (β=.04, P<.01) compared with their US-born counterparts. In contrast, foreign-born respondents who migrated at later ages showed disability trajectories similar to US-born respondents. Married respondents had a lower level of disability (β= -.14, P<.01) and a lower rate of accumulation over time (β= -.02, P=.001) compared with participants who were not married.Discussion: Mexican Americans who migrate at younger ages may experience greater disability over time; however, family support may help mitigate the accumula­tion of disability among older Mexican Americans.Ethn Dis. 2021;31(2):253-262; doi:10.18865/ed.31.2.253

The anchoring vignette method is designed to improve comparisons across population groups and adjust for differential item functioning (DIF). Vignette questions are brief de­scriptions of hypothetical persons for respondents to rate. Although this method has been adopted widely in health surveys, there remain challenges. In particular, vignettes are com­plex, increasing survey time and respondent burden. Further, the assumptions underlying this method are often violated. To overcome such challenges, this paper introduces an inno­vative technique, namely image anchoring vignettes, conveying vignette information with varying health levels in images. We conducted a cross-cultural experimental study to ex­amine the performance of image and standard text vignettes in terms of response time, how well they satisfy the assumptions, and their DIF-adjusting quality using a confirmatory factor analysis. The study revealed that respondents can better differentiate the intensity levels of the three vignettes in the image vignette condition, compared to text vignettes. Response consistency assumption appears to be better satisfied for image vignettes than text vignettes. Using well-designed image vignettes greatly reduces survey time without losing the DIF-adjustment quality, indicating the potential of image vignettes to improve overall efficiencies of the anchoring vignette method. Improving vignette equivalence (i.e., minimizing different interpretations of vignettes by different groups), remains a challenge for both text and image vignettes. This study generates new insights into the design and use of image anchoring vignettes.

In September 2008, the AAPOR Executive Council established an Opt-In Online Panel Task Force and charges it with "reviewing the current empirical findings related to opt-in online panels utilized for data collection and developing recommendations for AAPOR members." The council further specified that the charge did not include development of best practices, but rather would "provide key information and recommendations about whether and when opt-in panels might be best utilized and how best to judge their quality." The task force was formed in October 2008. This is its report. Adapted from the source document.
