Ego-syntonicity in responses to items in the California Psychological Inventory

Responding to items on a personality questionnaire can evoke a variety of feelings, from discomfort to indifference to pleasure. Harrison Gough reported that when he wrote items for the California Psychological Inventory (CPI; Gough & Bradley, 1996), he tried to make the items as ego-syntonic as possible. Ego-syntonic items are those “which a respondent finds congenial, and on which giving an opinion is a rewarding act” (Gough & Bradley, 1996, p. 10). The present study asked 79 respondents to report how they felt after answering each CPI item. Average affect ratings were above neutral for a majority of items, indicating that Gough had some success in writing ego-syntonic items. Differences in item ego-syntonicity were attributable to other item characteristics. Respondents disliked responding to relatively odd and ambiguous items, items with linguistic negations, and items referring to negative feelings and situations. As predicted by Gough, respondents enjoyed responding to items on the communality scale, items with which most people agree. They also enjoyed items that referred to positive emotions and attitudes and to items indicating extraversion, conscientiousness, low neuroticism, and openness to experience. Highly ego-syntonic items were found to be more valid than less ego-syntonic items. Individuals who reported disliking many items were found to be socially anxious. The relation between reports of liking or disliking items, identity, and reputation are discussed, and further research on item response dynamics and validity is proposed.     

Do personality scale items function differently in people with high and low IQ?

Intelligence differences might contribute to true differences in personality traits. It is also possible that intelligence might contribute to differences in understanding and interpreting personality items. Previous studies have not distinguished clearly between these possibilities. Before it can be accepted that scale score differences actually reflect personality differences, personality items should show measurement invariance. The authors used item response theory to test measurement invariance in the five-factor model scales of the International Personality Item Pool (IPIP) and NEO-Five-Factor Inventory (NEO-FFI) across two groups of participants from the Lothian Birth Cohort 1936 with relatively low and high cognitive abilities. Each group consisted of 320 individuals, with equal numbers of men and women. The mean IQ difference of the groups was 21 points. It was found that the IPIP and NEO-FFI items were measurement invariant across all five scales, making it possible to conclude that any differences in IPIP and NEO-FFI scores between people with low and high cognitive abilities reflected personality trait differences.     

Trait means and desirabilities as artifactual and real sources of differential stability of personality traits

Using data from 3 personality trait inventories and 7 samples, we show that trait items that have means near the scale midpoint and that vary more in their perceived desirability (e.g., items related to dominance, creativity, traditionalism, and organization) tend to be more stable over time, whereas items with means near the scale maximum or minimum and that vary less in their perceived desirability (e.g., items related to agreeableness, intellect, and reliability) tend to be less stable. Our findings indicate that items with means near the scale maximum or minimum have lower stabilities primarily due to having lower measurement dependability (i.e., short-term stabilities unlikely to reflect true change). However, items varying more in their desirability are more stable even after accounting for measurement dependability, consistent with the view that trait stability is facilitated in part by individuals actively working to develop in the direction they find desirable.     

A Measurement Model for Likert Responses That Incorporates Response Time

This article describes a model for response times that is proposed as a supplement to the usual factor-analytic model for responses to graded or more continuous typical-response items. The use of the proposed model together with the factor model provides additional information about the respondent and can potentially increase the accuracy of the individual trait estimates. First, the rationale of the model is discussed in relation to previous developments in binary responses. Second, procedures for fitting the model and for assessing model-data fit at both overall and individual level (person-fit) are proposed. Third, the usefulness of the model and its potential applications in the typical-response domain are discussed. All the proposed developments are used in 2 empirical applications in the personality domain. The first application analyzes 2 scales from a Big Five questionnaire. The second example analyzes a sociability scale developed from Eysenck's questionnaires.     

Towards More Rigorous Personality Trait–Outcome Research

Much of personality research attempts to identify causal links between personality traits and various types of outcomes. I argue that causal interpretations require traits to be seen as existentially and holistically real and the associations to be independent of specific ways of operationalizing the traits. Among other things, this means that, to the extents that causality is to be ascribed to such holistic traits, items and facets of those traits should be similarly associated with specific outcomes, except for variability in the degrees to which they reflect the traits (i.e. factor loadings). I argue that, before drawing causal inferences about personality trait–outcome associations, the presence of this condition should be routinely tested by, for example, systematically comparing the outcome associations of individual items or facets, or sampling different indicators for measuring the same purported traits. Existing evidence suggests that observed associations between personality traits and outcomes at least sometimes depend on which particular items or facets have been included in trait operationalizations, calling trait‐level causal interpretations into question. However, this has rarely been considered in the literature. I argue that when outcome associations are specific to facets, they should not be generalized to traits. Furthermore, when the associations are specific to particular items, they should not even be generalized to facets. Copyright © 2016 European Association of Personality Psychology     

Factor-analytic Procedures for Assessing Response Pattern Scalability

This paper proposes procedures for assessing the fit of a psychometric model at the level of the individual respondent. The procedures are intended for personality measures made up of Likert-type items, which, in applied research, are usually analyzed by means of factor analysis. Two scalability indices are proposed, which can be considered as factor-analytic counterparts of the lo and lz IRT-based person-fit indices. The present indices can be derived both as likelihood-based measures and as residual measures, and this makes it possible to relate them with previous methodologies such as Bollen's residual analysis and Lanning's scalability index. The indices are intended to be used mainly as exploratory devices, and a factor-analytic version of the person response curve is also proposed as a tool for obtaining further information about the possible causes of misfit. The behavior of the procedures is assessed by means of simulation studies. Finally, an empirical example in personality measurement shows how the procedures can be used in applied research.     

Inconsistent responding to repeated MMPI items: is its major cause really carelessness?

Previous authors have recommended using the number of inconsistent responses given to repeated MMPI items as a measure of the carelessness with which an individual has responded to the test. Such a recommendation assumes that a respondent who reads the items carefully must necessarily give an identical response to both presentations of the same item. Contrary to this assumption of a single cause, three potential causes of inconsistency--maladjustment, carelessness, and indecision--were investigated among 202 normal undergraduates who responded to the whole MMPI twice. The results suggest that indecision may be a more important cause of inconsistency than carelessness, thereby calling into question the use of inconsistencies on repeated MMPI items as a "carelessness" scale. Implications regarding the processes involved in responding to personality items are discussed.

Evidence for extending the circumplex model of personality trait language to self-reported moods

We show that self-ratings by 141 undergraduates on 17 items form a circumplex that closely agrees with Conte and Plutchik's (1981) circumplex of personality traits. The order of items on a circumplex, generated by self-ratings following a here-and-now instruction set, scarcely differs from that of a circumplex representing the same ratings averaged over a 2-week period. The configuration becomes more elliptical as one moves from the state-like measures (here-and-now ratings) to pure trait measures (averages), but measurement bias is shown to be the most probable cause of the distortion. Allowing for the limitations of small samples of items and raters, the findings show that the circumplex model represents a valid theoretical construct and does not arise from measurement error or from an illusory implicit personality theory.     

项目表述效应的统计控制：以中文版生活定向测验为例

本研究以中文版生活定向测验（LOT-R）为例,使用CTCM和CTCU方法进行建模,旨在探讨中文表述的量表中是否存在项目表述效应以及影响项目表述效应的特质因素。采用中文版生活定向测验等量表组成的问卷对334名大学生进行测试。结果表明,中文版LOT-R存在项目表述效应,是一种反向题的项目表述效应,也可称为语言标签效应;在分离了反向题项目表述效应后,发现中文版LOT-R只存在乐观因子,而不再有悲观因子。这表明乐观-悲观同属于一种人格特质,而非两种不同的人格特质;反向题项目表述效应是一种结构性误差,会导致量表结构的扭曲。研究还发现担心错误和父母期望与反向题项目表述效应存在显著的负相关,表明越是担心错误或父母期望水平越高的被试,他们对反向题的项目表述效应（语言标签效应）越小。社会赞许性对反向题项目表述效应没有影响。     

“… And How About Now?”: Effects of Item Redundancy on Contextualized Self‐Reports of Personality

A common method of studying cross-situational variation in personality involves asking people to describe their behavior in several different contexts. Although this approach is intuitively appealing, it introduces a great deal of redundancy into the measurement process and may affect the interpretation of contextualized self-reports. Specifically, when participants are asked the same questions repeatedly in a single questionnaire, they may be compelled to focus on how their behavior is different. We tested this hypothesis by experimentally manipulating the number of contexts that were included in a measure of role-related personality. In 2 experiments (Study 1 N=377, Study 2 N=524), we found that multiple-role questionnaires produced greater variation in trait levels across roles, larger differences between general and role-specific ratings, and weaker correlations between general and role-specific ratings than single-role questionnaires. These findings illustrate how the measurement process can have an effect on the variability of responses to contextualized self-reports.     

Validating a new method for quantifying traits: The computer-administered visual analog

This article introduces a new method for assessing personality traits that uses graphic rather than written items to facilitate the convergent validation of personality traits. A computer-administered visual analog procedure is presented that samples 40 equally spaced positions along a trait continuum five times. Examinees initiate each trial by pressing the space bar and end it by pressing either a “True” or “False” key indicating if that location describes them or not. Response time is measured in milliseconds. The majority answer determines the aggregate response and the median response time determines the latency for the aggregate response to each location on the trait continuum. This procedure enables an empirical measure of trait variability. Results indicated theoretically meaningful responses in 94 college students on each of two personality dimensions; extraversion and trait anxiety. The predicted inverted-U function was obtained for both personality dimensions such that the fastest response times were associated with 0 and 5 “True” responses, somewhat longer response times were associated with 1 and 4 “True” responses, and the longest times were associated with 2 or 3 “True” responses. Statistically significant and substantial validity coefficients were obtained with the Eysenck personality inventory extraversion scale, and the state-trait anxiety inventory, form Y-2.     

Reduced repetition suppression in the occipital visual cortex during repeated negative Chinese personality‐trait word processing

Reduced neural activation have been consistently observed during repeated items processing, a phenomenon termed repetition suppression. The present study used functional magnetic resonance imaging (fMRI) to investigate whether and how stimuli of emotional valence affects repetition suppression by adopting Chinese personality‐trait words as materials. Seventeen participants were required to read the negative and neutral Chinese personality‐trait words silently. And then they were presented with repeated and novel items during scanning. Results showed significant repetition suppression in the inferior occipital gyrus only for neutral personality‐trait words, whereas similar repetition suppression in the left inferior temporal gyrus and left middle temporal gyrus was revealed for both the word types. These results indicated common and distinct neural substrates during processing Chinese repeated negative and neutral personality‐trait words.

The Structure of Attitudes Toward Persons Who Are Deaf: Emotions,Values, and Stereotypes

The relative effects of affect, cognition, and stereotyping on attitudes toward persons who are deaf were studied. Respondents (N = 175) were initially asked to list terms or phrases that described (a) a typical person who is deaf, (b) the feelings the respondent experienced when thinking of a typical person who is deaf, and (c) beliefs about how a typical person who is deaf either facilitates or blocks cherished values held by the respondent. Then, each respondent evaluated as positive or negative each of the terms or phrases he or she wrote down. The relative effects of personality variables and structural variables on prejudicial attitudes were also assessed. Affect and past experience figured prominently in respondents' attitudes toward people who are deaf. Explanations for these findings and the implications of these results for prejudice formation and reduction were explored, especially in light of the passage, implementation, and enforcement of the Americans with Disabilities Act.     

Motives, values and moral judgments

This study examined McClelland's (1981) hypothesis that operant and respondent measures of personality are orthogonal and assess different dimensions of personality structure. An operant measure of motives, a sentence completion test, and two respondent measures of cognitive schema variables, the Rokeach Value Survey and the Defining issues Test, were administered to 311 subjects. As predicted and in support of McClelland's hypothesis, 69% of the correlations between the respondent measures were significant at the alpha .05 level of probability versus 14% of the correlations between the operant and respondent measures. Further, within the domain of cognitive schema variables, it was theoretically possible to predict which values would correlate with different levels of moral judgment. The findings were discussed in terms. of their implications for person x situation models of social interaction and the prediction of criterion variables from typologies of personality.     

The effect of face-to-face interviewing on personality measurement

In recent years, an increasing number of nationally representative surveys in the social sciences and economics have implemented the Big Five model of personality. While many personality inventories were originally developed in the context of self-administered questionnaires, they are often used by large surveys in face-to-face interview settings instead. Drawing on an experimental research design, we studied the effect of this switch in the method of data collection on measurement invariance as well as measurement error and interviewer effects in the Innovation Sample of the German Socio-Economic Panel (SOEP-IS). Although in some cases we found slightly stronger associations between interviewer and respondent personality in face-to-face settings, the results generally suggested strict measurement invariance–and therefore full comparability–across methods of data collection.     

A CONCEPTUAL AND EMPIRICAL REEXAMINATION OF THE MEASUREMENT OF THE SOCIAL DESIRABILITY OF ITEMS: IMPLICATIONS FOR DETECTING DESIRABLE RESPONSE STYLE AND SCALE DEVELOPMENT

This paper calls into question traditional methods of measuring the social desirability of items and their use in scale construction. First, we make explicit that the proper focus for desirability studies of items and traits are the rated desirabilities of the alternative item responses indicating different trait levels. Second, the results from our first study show that the relation between degree of endorsement of an item and its judged desirability level is often nonlinear and varies across items such that no general model of item desirability can be adopted that will accurately represent the relations across all items, traits, and trait levels. In addition, the nature of these relationships can vary depending on whether desirability is considered in a work or general context. Third, results from a second study indicate specifically that people when instructed to self-present in a maximally desirable manner will choose for some attributes a moderate level of endorsement (e.g., "agree") rather than a more extreme response option (e.g., "strongly agree"). Subjects offer several different reasons for viewing the less extreme response options, which yield more moderate trait level scores, as more desirable. These reasons are linked to perceptions of the more extreme response option as being associated with negative behaviors and concerns about how others will view a more extreme response to the item. Both studies indicate that desirable responding to personality items is more complex than previously believed.
