Are life satisfaction and self-esteem distinct constructs? A black South African perspective

As part of a longitudinal project on Quality of Life, a study was undertaken to extend the applicability of the 5-item Satisfaction With Life Scale, developed in the USA, in South Africa. Data on basic sociodemographic characteristics, the scale, and the 10-item Rosenberg Self-esteem scale were available for 360 Black South Africans (151 men and 209 women), ages 21 to 83 years (M = 38.6 yr., SD = 10.3). Factor analysis applied to scale scores gave two factors, accounting for 71% of the variance. Factor I was loaded by 10 Self-esteem items and Factor II by four of the five Life Satisfaction items. Coefficient alpha was .77 for the Satisfaction With Life Scale and .97 for the Rosenberg Self-esteem Scale. Life Satisfaction was related to Self-esteem (r = .17, p < .01). It was concluded that Life Satisfaction and Self-esteem appear to be distinct, unitary constructs, but responses to Item 5 on the Satisfaction With Life Scale require cautious interpretation and may contribute to the weak r, although so may the collectivist culture of Black South Africans.     

Working memory and intelligence: the same or different constructs?

Several investigators have claimed over the past decade that working memory (WM) and general intelligence (g) are identical, or nearly identical, constructs, from an individual-differences perspective. Although memory measures are commonly included in intelligence tests, and memory abilities are included in theories of intelligence, the identity between WM and intelligence has not been evaluated comprehensively. The authors conducted a meta-analysis of 86 samples that relate WM to intelligence. The average correlation between true-score estimates of WM and g is substantially less than unity (p=.479). The authors also focus on the distinction between short-term memory and WM with respect to intelligence with a supplemental meta-analysis. The authors discuss how consideration of psychometric and theoretical perspectives better informs the discussion of WM-intelligence relations.     

Specificity and detail in autobiographical memory: Same or different constructs?

Research on autobiographical memory has focused on whether memories are coded as specific (i.e., describe a single event that happened at a particular time and place). Although some theory and research suggests that the amount of detail in autobiographical memories reflects a similar underlying construct as memory specificity, past research has not investigated whether these variables converge. Therefore, the present study compared the proportion of specific memories and the amount of detail embedded in memory responses to cue words. Results demonstrated that memory detail and proportion of specific memories were not correlated with each other and showed different patterns of association with other conceptually relevant variables. When responses to neutral cue words were examined in multiple linear and logistic regression analyses, the proportion of specific memories uniquely predicted less depressive symptoms, low emotional avoidance, lower emotion reactivity, better executive control and lower rumination, whereas the amount of memory detail uniquely predicted the presence of depression diagnosis, as well as greater depressive symptoms, subjective stress, emotion reactivity and rumination. Findings suggest that the ability to retrieve specific memories and the tendency to retrieve detailed personal memories reflect different constructs that have different implications in the development of emotional distress.     

Basic value orientations and moral foundations: Convergent or discriminant constructs?

This study examined the structural and genetic links between value orientations, based on the theory of basic values, and moral concerns, based on moral foundations theory. We hypothesized both structural and genetic convergence of Conservation (versus openness to change) with Binding foundations and of Self-transcendence (versus self-enhancement) with Individualizing foundations. We analyzed self- and informant ratings from 924 participants with extended multitrait-multirater modeling and ran twin model analyses on self-ratings from 555 twin pairs. For Conservation and Binding foundations, we found partial convergence across different rater perspectives and a substantial genetic overlap, but also distinct genetic factors. Self-transcendence and Individualizing foundations were found to be structurally divergent, but genetically linked. We discuss the conceptual and measurement-related implications of the findings.     

Are alexithymia and Type D personality distinct or overlapping constructs? A confirmatory factor analysis of the Toronto alexithymia and Type D scales

Theoretically and conceptually the constructs of alexithymia and Type D personality share many common characteristics. Despite both measures being utilized widely in psychosomatic research, to-date no study has examined the constructs simultaneously. The present study was undertaken to determine if alexithymia and Type D personality are distinct or overlapping constructs. A cross-sectional sample of 1016 healthy participants completed the 20-item version of the Toronto alexithymia scale (TAS-20), and the Type D personality scale (DS14). Confirmatory factor analysis of the 14 items of the DS14, and 20 items of the TAS-20 was conducted. Based on the underlying theoretical structures of the DS14 and TAS-20 a five-factor model was examined (corresponding to the five subscales of the DS14 and TAS-20). The analysis revealed that the five factor model was an acceptable fit for the data (χ²/df = 4.7; CFI = .94, RMSEA = 0.06). These results provide evidence to suggest that alexithymia and Type D are distinct and separate constructs. However, future research should aim to replicate these findings in population and clinical samples.     

Artificial natural selection: Can supplemental feeding domesticate mosquitoes and control mosquito-borne diseases?

A new method is proposed for controlling mosquito-borne diseases. In particular, instead of trying to kill mosquitoes, we suggest provisioning them with food from artificial feeders. Because mosquito populations are frequently limited by ecological factors other than blood meals, such as the availability of egg-laying sites, feeding mosquitoes would not necessarily increase the total number of mosquitoes, but could reduce the number of human-drawn mosquito meals. Like mosquito traps, feeders could divert biting mosquitoes away from people by means of lures, but, after diversion, prevent subsequent human bites by satiating the mosquitoes instead of killing them. Mosquito feeders might reduce the problem of the evolution of resistance to control: in an ecology with mosquito feeders, which provide safe and abundant calories for adult female mosquitoes, there could be selection for preferring (rather than avoiding) feeders, which could eventually lead to a population of feeder-preferring mosquitoes. Artificial feeders also offer the chance to introduce novel elements into the mosquito diet, such as anti- malarial or other anti-parasitic agents. Feeders might directly reduce human bites and harnesses the power of natural selection by selectively favoring feeder-preferring (rather than trap-resistant) mosquitoes.     

Concepts of health and illness: different constructs or variations on a theme?

Although health and illness concepts are thought to be important mediators of health and illness behaviors, little work has been done examining health concepts, and no research has examined the two conceptual structures simultaneously. This study examined concepts of health and illness in 218 adolescents between the ages of 11 and 18 years. Results were consistent with the hypothesis that concepts of health and illness are not opposite ends of a single health dimension, but reflect different and overlapping constructs. The degree of overlap varied as a function of age, with health concepts showing less emphasis on "the absence of illness" with greater maturity. The results suggest that models of health behavior that focus on illness avoidance neglect many components of health salient to lay persons.     

What if there were no psychometrics?: constructs, complexity, and measurement

McGrath (2005/this issue) has published a very significant article; it is significant because it examines the substantive issue of construct validity in a simple and informative way, noting the confusions apparent in how constructs and their variables are defined, used, and interpreted within the domain of personality and individual differences. This is a careful, thoughtful, article that quietly proceeds to outline the problems with current thinking and approaches to defining and using constructs in psychology. McGrath also suggests how some of these problems might be addressed. I note that McGrath appears to miss what might be considered an obvious rejoinder to some of his arguments, that is, the use of latent variable and item response theory. Some consideration is given to these arguments. However, a cursory examination shows that although these new methodologies offer many opportunities for new stochastic questionnaire data modeling and the construction of "instant" latent variables, the same problems caused by lack of attention to measurement and meaning remain. I find I am in agreement with many of the author's views and arguments, but I also find myself wondering whether modern psychometrics and individual differences research methods is now so dominated by psychological statisticians that any thought of substantive scientific innovation in this area that deals more properly with measurement and meaning is long gone. I think the answers to the question "What if there was no psychometrics?" would be most illuminating.     

Ideals,oughts, and self-regulation: Are there qualitatively distinct self-guides?

Self-regulation, the ability to regulate one's emotions and behavior with respect to important goals, is an important function. While a number of different self-regulatory models exist, self-discrepancy theory (SDT: Higgins, 1987, 1989a, 1989b) is the only model which proposes that there are distinct self-guides, the ideal and the ought self. Discrepancies or congruencies between the actual self and each type of self-guide is proposed to result in unique emotional and behavioral consequences. Some recent research findings have failed to demonstrate these unique consequences, causing the proposed distinction between the self-guides to be questioned in the literature. This paper suggests that this conclusion is based on the assumption that these effects must occur in every case. We argue that SDT does not propose that unique relationships between discrepancies and either emotions or behavior always occur; rather, it specifies moderators of these relationships. A review of recent research examining the effects of these moderators highlights not only that, indeed, such moderating effects are found, but also in some cases the moderating effect is different for relationships between emotions and the two types of discrepancies. It is concluded that these two different types of evidence, namely, the existence of moderator variables and their differential effects on ideal and ought self-regulation, provide compelling support for the distinct nature of the ideal and the ought self-guides.     

General and relationship-based perceptions of social support: are two constructs better than one?

Two hypotheses derived from a theory of perceived social support were investigated: (a) relationship-based perceptions of social support are distinct from general perceptions of support, and (b) measures of each construct contribute uniquely to the prediction of loneliness. Ninety-four male and 116 female undergraduates completed measures of loneliness and general perceived social support and the Quality of Relationships Inventory, a new instrument to assess relationship-based perceptions of social support, conflict, and depth in specific relationships. General and relationship-based perceptions of social support were found to be related, but empirically distinct, constructs. Relationship-based perceptions of support and conflict from mothers and friends each added to the prediction of loneliness after considering the contribution of general perceived social support. Implications of these findings for understanding the perceived social support construct are discussed.     

Optimism and pessimism in the context of health: bipolar opposites or separate constructs?

One difficulty plaguing research on dispositional optimism and health is whether optimism and pessimism are bipolar opposites or constitute distinct constructs. The present study examined the Life Orientation Test to determine whether the two-factor structure is explained by method bias (due to measurement) or substantive differences. The authors compared three measurement models: bipolar, bivariate, and method artifact. Optimism and pessimism emerged as distinct constructs due to substantive differences. The authors also considered the validity of optimism and pessimism, examining their relations with psychological and physical health outcomes. Optimism and pessimism were more similar in relation to psychological health than to other health-related behavior or physical health outcomes. However, a strongly interpretable pattern for the relation of optimism and pessimism to the health outcomes did not emerge. Further research may benefit from considering optimism and pessimism as bivariate and also should consider the conceptual components and behavioral mechanisms specific to each variable.     

Bullies,aggressive victims,and victims: Are they distinct groups?

This study analyzed a sample representing six middle schools that included 206 pure bullies, 514 pure victims, and 206 aggressive victims. Aggressive or provocative victims are students who have been bullied but also bully other students. This research assessed whether aggressive victims engaged in different patterns of behavior and had dissimilar socialization experiences than pure bullies and pure victims. Factors that were considered include measures of parental socialization, family conflict, reactive and proactive aggression, low self‐control, social bonds, and other relevant factors, including demographic characteristics. Logistic regression analyses indicated that aggressive victims engaged in significantly different patterns of behavior than pure victims and pure bullies. The analyses also indicated that the socialization experiences of middle school aggressive victims more closely resembled the socialization experiences of pure bullies than pure victims. Aggr.

Are selective adaptation and contrast effects really distinct?

Although there is evidence that selective adaptation and contrast effects in speech perception are produced by the same mechanisms, Sawusch and Jusczyk (1981) reported a dissociation between the effects and concluded that adaptation and contrast occur at separate processing levels. They found that an ambiguous test stimulus was more likely to be labeled b following adaptation with [pha] and more likely to be labeled p following adaptation with [ba] or [spa] (the latter consisting of [ba] preceded by [s] noise). In the contrast session, where a single context stimulus occurred with a single test item, the [ba] and [pha] contexts had contrastive effects similar to those of the [ba] and [pha] adaptors, but the [spa] context produced an increase in b responses to the test stimulus, an effect opposite to that of the [spa] adaptor. One interpretation of this difference is that the rapid presentation of the [spa] adaptor gave rise to "streaming," whereby the [s] was perceptually segregated from the [ba]. In our experiment, we essentially replicated the results of Sawusch and Jusczyk (1981), using procedures similar to theirs. Next, we increased the interadaptor interval to remove the likelihood of stream segregation and found that the adaptation and contrast effects converged.     

Thalamic stuttering: a distinct clinical entity?

A 38-year-old right-handed male with no history of speech or language problems presented with neurogenic stuttering following an ischaemic lesion of the left thalamus. He stuttered severely in propositional speech (conversation, monologue, confrontation naming, and word retrieval) but only slightly in non-propositional speech (automatic speech, sound, word and sentence repetition, and reading aloud). It is suggested that thalamic stuttering may constitute a distinct clinical entity.     

Facial first impressions and partner preference models: Comparable or distinct underlying structures?

Given the frequency of relationships nowadays initiated online, where impressions from face photographs may influence relationship initiation, it is important to understand how facial first impressions might be used in such contexts. We therefore examined the applicability of a leading model of verbally expressed partner preferences to impressions derived from real face images and investigated how the factor structure of first impressions based on potential partner preference-related traits might relate to a more general model of facial first impressions. Participants rated 1,000 everyday face photographs on 12 traits selected to represent (Fletcher, et al. 1999, Journal of Personality and Social Psychology, 76, 72) verbal model of partner preferences. Facial trait judgements showed an underlying structure that largely paralleled the tripartite structure of Fletcher et al.'s verbal preference model, regardless of either face gender or participant gender. Furthermore, there was close correspondence between the verbal partner preference model and a more general tripartite model of facial first impressions derived from a different literature (Sutherland et al., 2013, Cognition, 127, 105), suggesting an underlying correspondence between verbal conceptual models of romantic preferences and more general models of facial first impressions.     

Goals or semantic constructs? Different choice setting and choice goal activation

The researcher of this paper contributes to the literature by identifying nuances among three types of choice settings that are likely to activate choice‐related goals and their implications for product evaluation. First, the research verifies that choice settings can activate choice‐related goals, for example, simplifying a choice. Second, it is proposed and shown that choice settings activate goals, not semantic constructs. Third, this research attempts to shed light on some nuances among different choice settings, which vary in the degree of cognitive effort used to compare alternatives. The results aid in understanding how three different choice settings can activate choice‐related goals. Fourth, the research proposes that goal activation has an implication for product evaluation, offering a new perspective to preference and choice reversal literature. Five experiments were conducted to test the hypotheses.     

Visual search: efficiency continuum or distinct processes?

Whether visual search involves two distinct processes—traditionally referred to as serial and parallel— or a single process operating on a continuum of efficiency or speed, is an issue with a long history in the study of attention. On the basis of the unimodality of search slope distributions in a very large data set, Wolfe (1998) argued for a continuum model. Reanalysis of this data set using statistical procedures more appropriate for adjudicating between continuous and discontinuous models supports the existence of two distinct processes.     

Drive for thinness and drive for muscularity: Opposite ends of the continuum or separate constructs?

The goal of this study was to examine whether the drive for thinness and the drive for muscularity occur concurrently among late adolescents and to understand the body attitudes associated with desiring a thinner and/or a more muscular physique. Participants included 235 college freshmen who participated in a larger study of body image and eating attitudes. The majority of individuals reported having both a high drive for thinness and a high drive for muscularity (65.4%). Additionally, the presence of both drives significantly predicted body compulsivity and body anxiety among females, and body-esteem among males. Results of the current study provide considerable evidence that a drive for thinness and a drive for muscularity are not mutually exclusive. Furthermore, the degree to which an individual strives for thinness and/or muscularity has differential effects on their body attitudes.     

Clarifying the relationship between AS dimensions and PTSD symptom clusters: are negative and positive affectivity theoretically relevant constructs?

The association between anxiety sensitivity (AS) and posttraumatic stress disorder (PTSD) has been established in contemporary literature; however, research is divided over the nature of specific relationships between AS dimensions and PTSD symptoms clusters. Further, a paucity of research has examined the AS and PTSD relationship while accounting for theoretically relevant variables, such as negative (NA) and positive affect (PA). The purpose of the current study was twofold: first, to clarify divergent findings regarding the contribution of AS dimensions to PTSD symptom clusters, and, second, to further assess the relevance of NA and PA within the AS/PTSD relationship. Hierarchal regression analyses showed that, beyond shared variance attributable to NA and PA, AS somatic concerns were significantly associated with three of four PTSD symptom (i.e., reexperiencing, numbing, hyperarousal), AS cognitive concerns were only associated with hyperarousal, and AS socially observable symptoms were not significantly associated with any PTSD symptom clusters. These findings suggest that AS somatic concerns are the most robust predictor of variance within the AS/PTSD relationship and further clarify the theoretical importance of NA and PA within this relationship. Comprehensive results, implication, and directions for future research are discussed.
