Bad news indeed for Ryff’s six-factor model of well-being

Springer and Hauser (An Assessment of the Construct Validity of Ryff’s Scales of Psychological Well-Being: Method, Mode, and Measurement Effects. 2006. Social Science Research 35) tested one key aspect of the validity of Ryff’s six-factor model of psychological well-being (RPWB), namely, whether there is substantial independent variation among the six factors. In several large and heterogeneous samples, under a variety of model specifications, and using various sets of RPWB items, we found very high factor correlations among the dimensions of well-being, especially personal growth, purpose in life, self-acceptance, and environmental mastery. That is, the six-factor model makes theoretical claims that do not yield large or consistent empirical distinctions when standard measures and instrumentation are used. Where Ryff and Singer’s comment (Best News Yet on the Six-Factor Model of Well-Being. 2006. Social Science Research 35) refers directly to that analysis, their methodological discussion is most often irrelevant or incorrect. Their text largely ignores and fails to challenge our strong empirical findings about the factorial structure of well-being. In this response, we reinforce these findings and their implications for the (in)validity of the six-factor well-being model as implemented by Ryff. We also explain why Ryff and Singer’s lengthy review of studies that show differential relationships of RPWB factors with other variables should be interpreted with far greater caution than Ryff and Singer recognize. We offer recommendations for analyzing RPWB items in surveys that have already been conducted, but we also emphasize the need for a thorough rethinking of the measurement and dimensionality of psychological well-being.     

The derivation of a brief Student Nurse Stress Index

The lack of an adequate measure of perceived sources of stress for student nurses led to the construction of the Student Nurse Stress Index (SNSI). Responses from 235 first-year student nurses to 35 items from the Beck and Srivastava Stress Inventory (Beck, and Srivastava, 1991), and 15 new items, were subjected to exploratory factor analysis using principal components analysis and oblimin rotation. A reliable 22-variable solution with a simple oblique structure including Academic load, Clinical sources, Interface worries, and Personal problems factors was obtained in this initial sample, and confirmed at an exploratory level in a further independent validation sample of 188 first-year students. Confirmatory factor analysis established the four-factor model in the first sample, but required that three variables load onto more than one factor. This more complex four-factor model was confirmed using independent data from the validation sample, and the total invariance of factor loadings and factor covariances of this more complex four-factor model was established in both data sets simultaneously using multi-sample techniques. The SNSI shows cross-sample factor congruence, good internal reliabilities, and concurrent and discriminant validity across a range of reporting conditions.     

Using the End‐User Computing Satisfaction (EUCS) Instrument to Measure Satisfaction with a Web Site

The purpose of this study is to revise and revalidate the End‐User Computing Satisfaction (EUCS) instrument to measure satisfaction with a Web site from a usability perspective. This study is especially important given the increased significance of the Web and the uniqueness of the Web as a computing environment. A total of 176 students participated in a lab simulation that involved a usability evaluation of the Lands' End Web site ( http://www.landsend.com ). Students were asked to complete a set of tasks, record their answers, and then complete the EUCS instrument. Confirmatory factor analysis and invariance analyses were conducted to test the reliability, validity, and generalizability of the revised EUCS. The results show that the EUCS is a valid and robust instrument in the Web environment but that one of the subfactors, timeliness, will need further refinement in the future. Usability practitioners can use the EUCS to measure end‐user satisfaction with a Web site and use the feedback for improving Web‐site design. We describe a case study of an actual usability application that utilized the revised EUCS effectively to support the design of building supply Web sites involving two types of end users, homeowners and contractors. We also propose a typology that researchers can use as a starting point to judge when it is necessary to revalidate an instrument like the EUCS. Finally, we discuss the limitations of our study and present avenues for future research.     

On the Measurements of Board Composition: Poor Consistency and a Serious Mismatch of Theory and Operationalization

Over two dozen operationalizations of board composition can be identified from the empirical literature. A structural equations confirmatory factor analysis (LISREL 8.03) suggests that these operationalizations do not constitute a single construct of board independence. Instead, analyses strongly indicate three separate constructs. Common operationalizations of board composition, then, are neither tenable surrogates for one another nor are they interchangeable. Implications for empirical aggregation of studies, theory/measurement convergence, and the current corporate governance public policy debate are discussed.     

HIV and PTSD: A Confirmatory Factor Analysis of the PCL Screening Instrument

ABSTRACT

The findings are reported from a confirmatory factor analysis (CFA) of the posttraumatic screening checklist (PCL) created by Weathers et al. (1993) Weathers, F. W., Litz, B. T., Herman, D. S., Huska, J. A. and Keane, T. M. 1993. The PTSD Checklist (PCL): Reliability, validity, and diagnostic utility, Presented at Annual Meeting of the International Society for Traumatic Stress Studies, San Antonio, TX. [Google Scholar]. One hundred and eighty-six individuals receiving either preventive HIV information or ongoing HIV counseling from community-based AIDS organizations in the New York City area completed the PCL checklist. To identify a model relevant to screening posttraumatic stress disorder (PTSD) within the HIV/AIDS community, six CFAs were conducted. Results indicated that the PTSD scale should include attention to four general areas: a) reexperiencing the traumatic event; b) avoidance of anything associated with the traumatic event; c) a sense of numbing; and d) a hyperarousal state. The CFA produced a more concise model of 12 items, relevant to the HIV community. Future research suggests that the relationships between different components of trauma exposure and different manifestations of PTSD should be examined further.     

Confirmatory Bias and Confirmatory Distortion

SUMMARY

The author reviews research on confirmatory bias, discusses its role in evaluations of comparative custodial fitness, and creates a distinction between confirmatory bias and confirmatory distortion, in which there is an indisputably conscious endeavor to find and report information that is supportive of one's favored hypothesis. Information is provided concerning the dynamics of confirmatory bias and distortion, the ways in which these phenomena manifest themselves, and the ways in which they can be addressed by reviewers and by cross-examining attorneys.     

Determining Uses and Gratifications for the Internet

Uses and gratifications (U&G) is a media use paradigm from mass communications research that guides the assessment of consumer motivations for media usage and access. It has been used previously in research and decision making related to the promotion of emerging radio and television media. Recent adaptations of U&G research to the Internet are incomplete and have not identified important new Internet‐specific gratifications. This paper empirically derives dimensions of consumer Internet use and usage gratifications among customers of a prominent Internet Service Provider (ISP). Results describe three key dimensions related to consumer use of the Internet, including process and content gratifications as previously found in studies of television, as well as an entirely new social gratification that is unique to Internet use. All three dimensions of gratification are relevant to managing the Internet as a commercial medium, and measures developed from the gratification profiles identified here can serve as trait‐valid scales in future Internet and e‐commerce research.     

城中村农民市民化演变效果的实证研究

基于市民身份的社会学视角,以城中村农民市民化的演变效果为焦点,提出了一个市民性的六因子概念模型：市民理性精神、市民职业性、市民生活方式、市民社会保障性、市民社会参与性及市民政治自治性。从保定市薛刘营村抽取267位村民收集数据资料,分别用一阶和二阶验证性因子分析模型对数据资料进行拟合,结果表明,村民市民化六个维度的演变呈现出不同步性;同时,这六个因子又共同组成了一个更高级因子——市民性的完整表征。最后提出需要通过市民教育、就业服务、完善市民权制度和建立市民化监测指标体系来进一步促进城中村村民的市民化进程。     

Dimensionality of the Chinese Dyadic Adjustment Scale Based on Confirmatory Factor Analyses

Based on the responses of 1,501 Chinese married adults to the Chinese version of the Dyadic Adjustment Scale (C-DAS), confirmatory factor analyses showed that four factors were abstracted from the C-DAS (Dyadic Consensus, Dyadic Cohesion, Dyadic Satisfaction and Affectional Expression) and these four primary factors were subsumed under a second-order Dyadic Adjustment factor. Invariance of the factorial structure between men and women were also found. The findings suggest that the dimensions of marital adjustment assessed by the Dyadic Adjustment Scale [Spanier (1976). Journal of Marriage and the Family, 38, 15–28] can be replicated in the Chinese culture, although some minor refinement might be needed. The present findings also provide support for the use of the C-DAS for assessing marital adjustment in Chinese people.     

Analyzing sub-population profiles and risk factors for school bullying

Drawing from a local sample of 1822 7th and 8th grade students, this study used Latent Class Analysis (LCA) and Latent Class Regression Analysis (LCRA) to identify sub-population profiles and risk factors for school bullying. Four sub-population profiles of school bullying risk were yielded from this approach. These profiles included students who presented little need for formal services as well as students who manifested needs for wrap-around support. Importantly, additional regression analyses related student membership in particular risk profile groups to the support they receive from peers, teachers, and parents. Several significant practice implications for bullying prevention and Response-to-Intervention (RTI) frameworks accompany the findings. Above all, school bullying interventions should be implemented with prudence because even the best intended ones carry the potential for harm.
