This study examined the death attitudes of a number of prominent thanatologists over a 15-year span. In 1973, 40 (30 men, 10 women) invited participants at a conference on death and dying were surveyed concerning their attitudes toward dying and death using Feifel's Death Attitudes Questionnaire, a Death Semantic Differential Test, and a Death Metaphors Test. Fifteen years later, 25 (62.5 percent) of these individuals again gave their responses to the three measures. Analyses were limited to basic group comparisons because the original raw data were unavailable. Respondents were primarily behavioral scientists (64 percent), but sizeable minorities were from medicine/nursing (24 percent) and religion/philosophy (12 percent). They were about equally divided in the religious (45 percent) versus non-religious (55 percent) categories, and rated themselves as being fairly satisfied with themselves and life in general. Almost two-thirds reported some fear of death (64 percent at both time points), and only 20 percent indicated that the idea of their own death was “easy to accept.” Most (60–64 percent) reported a fear of the personal consequences of death, including pain and an inability to have experiences or complete projects, with the next most pervasive fear (36–40 percent) being the consequences to loved ones, including pain, loss, and financial difficulties. Concerning what occurs after death, about half of the respondents (48–52 percent) indicated that death is the end of existence, another 24–30 percent were uncertain and 16–17 percent believed in the continued existence of a soul. Death attitudes were remarkably stable over the 15-year interval. The major difference found was a lessening of death fear from 1973 to 1988 ( p < .002), that subjects attributed primarily to their ongoing conversations about death and dying (56 percent), and the deaths of family and friends (32 percent).

Background. The Oxford Happiness Inventory (OHI) is a self-report tool to measure happiness. A brief review of previous studies on OHI showed the lack of evaluation of OHI fairness/equivalence in measuring happiness among identified groups. Methods. To examine the psychometric properties and measurement invariance of the OHI, responses of 500 university students were analyzed using item response theory and ordinal logistic regression (OLR). Relevant measures of effect size were utilized to interpret the results. Differential test functioning was also evaluated to determine whether there is an overall bias at the test level. Results. OLR analysis detected four items across gender and two items across marital status to function differentially. An assessment of effect sizes implied negligible differences for practical considerations. Conclusions. This study was a significant step towards providing theoretical and practical information regarding the assessment of happiness by presenting adequate evidence regarding the psychometric properties of OHI.

Although the racial/ethnic demographics in the United States are changing, few studies evaluate the cultural and linguistic responsiveness of commonly used autism spectrum disorder screening and diagnostic assessment measures. The purpose of this study is to evaluate item and test functioning of the Autism Spectrum Rating Scales (ASRS) in a sample of racially/ethnically diverse parents of children (nonclinical) between the ages of 6–18 ( N = 806). This study is a follow-up to a prior publication examining the factor structure of the ASRS among a similar sample. The present study furthers the examination of measurement invariance of the ASRS in racially/ethnically diverse populations by conducting differential item functioning and differential test functioning with a larger sample. Results indicate test-level invariance; however, five items are noninvariant across parent reporters from different racial/ethnic groups. Implications for practice and directions for future research are discussed.
