Should we trust web-based studies? A comparative analysis of six preconceptions about internet questionnaires

The rapid growth of the Internet provides a wealth of new research opportunities for psychologists. Internet data collection methods, with a focus on self-report questionnaires from self-selected samples, are evaluated and compared with traditional paper-and-pencil methods. Six preconceptions about Internet samples and data quality are evaluated by comparing a new large Internet sample (N = 361,703) with a set of 510 published traditional samples. Internet samples are shown to be relatively diverse with respect to gender, socioeconomic status, geographic region, and age. Moreover, Internet findings generalize across presentation formats, are not adversely affected by nonserious or repeat responders, and are consistent with findings from traditional methods. It is concluded that Internet methods can contribute to many areas of psychology.     

A coefficient alpha for test-retest data

Transient errors are caused by variations in feelings, moods, and mental states over time. If these errors are present, coefficient alpha is an inflated estimate of reliability. A true-score model is presented that incorporates transient errors for test-retest data, and a reliability estimate is derived. This estimate, referred to as the test-retest alpha, is less than coefficient alpha if transient error is present and is less susceptible to effects due to item recall than a test-retest correlation. An assumption underlying the test-retest alpha is essential tau equivalency of items. A test-retest split-half coefficient is presented as an alternative to the test-retest alpha when this assumption is violated. The test-retest alpha is the mean of all possible test-retest split-half coefficients.     

The precarious couple effect: verbally inhibited men + critical, disinhibited women = bad chemistry

When critical, verbally disinhibited women are paired with verbally inhibited men, relationship quality suffers, rendering the relationship precarious. This effect theoretically emerges when (a). verbally disinhibited women pair with relatively inhibited men (man-more-inhibited couples) and (b). the disinhibition of women in man-more-inhibited couples amplifies women's criticalness and alienates men. Three studies (Ns=437, 300, and 564) provided evidence that relationship quality suffered in man-more-inhibited couples; a 4th study (N=168) showed that the criticalness of women in man-more-inhibited couples did indeed undermine relationship quality. Implications for understanding the impact of gender expectations on relationships and for integrating behavioral and personological approaches to close relationships are discussed.     

Student athletes' perceptions of self

Several factors have been found to contribute to the development of the self in adolescents, including religion, race, competence, leadership, physical appearance, and gender. The purpose of this study was to describe the development of self-perception in adolescent athletes and make comparisons with respect to gender and class level. One hundred seventy-five high school athletes were administered Harter's (1988) Self-Perception Profile for Adolescents. The data were analyzed for both the overall sample and demographic subgroups. Males had a significantly higher mean score on athletic competence than did females. Males also viewed both athletic competence and social acceptance as significantly more important than did females. These findings are discussed in the context of relevant literature on adolescents' perceptions of self.     

Development of personality in early and middle adulthood: set like plaster or persistent change?

Different theories make different predictions about how mean levels of personality traits change in adulthood. The biological view of the Five-factor theory proposes the plaster hypothesis: All personality traits stop changing by age 30. In contrast, contextualist perspectives propose that changes should be more varied and should persist throughout adulthood. This study compared these perspectives in a large (N = 132,515) sample of adults aged 21-60 who completed a Big Five personality measure on the Internet. Conscientiousness and Agreeableness increased throughout early and middle adulthood at varying rates; Neuroticism declined among women but did not change among men. The variety in patterns of change suggests that the Big Five traits are complex phenomena subject to a variety of developmental influences.     

The do re mi's of everyday life: the structure and personality correlates of music preferences

The present research examined individual differences in music preferences. A series of 6 studies investigated lay beliefs about music, the structure underlying music preferences, and the links between music preferences and personality. The data indicated that people consider music an important aspect of their lives and listening to music an activity they engaged in frequently. Using multiple samples, methods, and geographic regions, analyses of the music preferences of over 3,500 individuals converged to reveal 4 music-preference dimensions: Reflective and Complex, Intense and Rebellious, Upbeat and Conventional, and Energetic and Rhythmic. Preferences for these music dimensions were related to a wide array of personality dimensions (e.g., Openness), self-views (e.g., political orientation), and cognitive abilities (e.g., verbal IQ).     

Controlling the Past to Control the Future: Christian Nationalism and Mandatory Patriotic Education in Public Schools

Recent debates about whether educators should teach America's racist history have sparked activism and legislation to ensure students are taught American history in such a way that promotes “patriotism,” amplifying cherished national myths, emphasizing American exceptionalism, and erasing negative historical facts. Building on insights from both social dominance theory and Christian nationalism research, we propose Christian nationalism combines legitimizing myths that whitewash America's past with authoritarian impulses and thus seeks to enforce “patriotic” content in public school classrooms. We also theorize this connection varies across racial, partisan, and ideological identities. Data from a nationally-representative survey of Americans affirm Christian nationalism is by far the leading predictor Americans believe “We should require public school teachers to teach history in a way that promotes patriotism.” This association is consistent across race (possibly due to divergent meanings of both “Christian nationalism” and “patriotism” across groups), but varies by partisanship and ideological identity for whites. Specifically, Christian nationalism brings whites who identify with the ideological and political left into complete alignment with their conservative counterparts who are already more likely to support mandatory patriotic education. Our findings provide critical context for ongoing battles over public-school curricula and education's role in perpetuating social privilege.     

Multinational data show that conspiracy beliefs are associated with the perception (and reality) of poor national economic performance

While a great deal is known about the individual difference factors associated with conspiracy beliefs, much less is known about the country-level factors that shape people's willingness to believe conspiracy theories. In the current article we discuss the possibility that willingness to believe conspiracy theories might be shaped by the perception (and reality) of poor economic performance at the national level. To test this notion, we surveyed 6723 participants from 36 countries. In line with predictions, propensity to believe conspiracy theories was negatively associated with perceptions of current and future national economic vitality. Furthermore, countries with higher GDP per capita tended to have lower belief in conspiracy theories. The data suggest that conspiracy beliefs are not just caused by intrapsychic factors but are also shaped by difficult economic circumstances for which distrust might have a rational basis.     

Organizational Image Assessment in the Health and Human Services Sector1

Five studies were conducted from 1976 to 1984 in southcentral Pennsylvania to evaluate the potential of bipolar ratings by adult user populations for assessing the general agency and/ or specific program image of service organizations in the not-for-profit sector. Statistically reliable differences in mean ratings on scales such as staff qualifications, physical accessibility, and so forth were found to distinguish image profiles and the clarity of image of three human service agencies within the same region of service, to detect change over a 6-year period in the image of individual agencies, and to be sensitive to the effects of management actions designed to modify the image of an in-patient psychiatric facility within a region. The demonstration that specific management interventions over a 2-year period were detectable by ratings along specifically relevant dimensions encourages the immediate application of this inexpensive feedback device by managers of human service agencies and the further investigation of user image ratings as a system output potentially amenable to control system analyses.
