The Recaptured Scale Technique: A Method for Testing the Structural Robustness of Personality Scales

Tellegen and Waller advocated a complex and time-consuming scale construction method that they called “exploratory test construction.” Scales that are constructed by this method—such as the Multidimensional Personality Questionnaire (MPQ)—are presumed to be more “psychologically coherent” and “robust” than scales constructed by other means. Using a novel procedure that we call the “recaptured scale technique,” we tested this conjecture by conducting a megafactor analysis on data from the 411 adult participants of the Minnesota Study of Twins Reared Apart who completed the MPQ, the MMPI, and the CPI. We extracted and obliquely rotated 21 factors from a matrix of gender-corrected tetrachoric correlations for the 1,102 nonredundant items of the three omnibus inventories. Robustness of the 11 MPQ scales was assessed by the degree to which these factors recaptured the MPQ item groupings. Our results showed that nine factors were clearly recognizable as MPQ scales and two additional factors represented a bifurcation of an MPQ scale. A higher-order factor analysis of all 21 factor scales yielded five factors that clearly resembled the Big Five. Our results provide strong support for (a) the method of exploratory test construction, (b) the structural robustness of most MPQ scales, and (c) the utility of the recaptured scale technique.     

Macaques can predict social outcomes from facial expressions

There is widespread acceptance that facial expressions are useful in social interactions, but empirical demonstration of their adaptive function has remained elusive. Here, we investigated whether macaques can use the facial expressions of others to predict the future outcomes of social interaction. Crested macaques (Macaca nigra) were shown an approach between two unknown individuals on a touchscreen and were required to choose between one of two potential social outcomes. The facial expressions of the actors were manipulated in the last frame of the video. One subject reached the experimental stage and accurately predicted different social outcomes depending on which facial expressions the actors displayed. The bared-teeth display (homologue of the human smile) was most strongly associated with predicted friendly outcomes. Contrary to our predictions, screams and threat faces were not associated more with conflict outcomes. Overall, therefore, the presence of any facial expression (compared to neutral) caused the subject to choose friendly outcomes more than negative outcomes. Facial expression in general, therefore, indicated a reduced likelihood of social conflict. The findings dispute traditional theories that view expressions only as indicators of present emotion and instead suggest that expressions form part of complex social interactions where individuals think beyond the present.     

Does psychosocial stress exacerbate avoidant responses to cancer information in those who are afraid of cancer? A population-based survey among older adults in England

Objective: Communication of cancer information is an important element of cancer control, but cancer fear may lead to information avoidance, especially when coping is low. We examined the association between cancer fear and cancer information avoidance, and tested whether this was exacerbated by psychosocial stress.

Design: Cross-sectional survey of 1258 population-based adults (58–70 years) in England.

Main outcome measures: Cancer fear (intensity and frequency), perceived psychosocial stress and cancer information avoidance. Control variables were age, gender, ethnicity, marital status and education.

Results: A quarter (24%) of respondents avoided cancer information. Ordinal logistic regression analyses showed main effects of psychosocial stress (OR = 1.17, 95% CI 1.07–1.29) and cancer fear: cancer information avoidance was lowest in those with no cancer fear (13%), followed by those with moderate (24%; OR = 2.15, 95% CI: 1.49–3.12), and high cancer fear (35%; OR = 3.90, 95% CI: 2.65–5.73). In the adjusted model, the interaction between cancer fear and stress was significant (OR = 1.14, 95% CI 1.004–1.29, p < .05): 40% of those with high fear/high stress avoided cancer information compared with 29% with high fear/low stress.

Conclusion: Cancer fear and psychosocial stress interact to produce disengagement with cancer-related information, highlighting the importance of affective processes to cancer control efforts.     

Coparenting Interventions for Fragile Families: What Do We Know and Where Do We Need To Go Next?

With a large and growing share of American families now forming outside of marriage, triangular infant–mother–father relationship systems in “fragile families” have begun to attract the interest of family scholars and clinicians. A relatively novel conceptualization has concerned the feasibility of intervening to support the development of a sustained and positive coparenting alliance between mothers and fathers who have not made an enduring relationship commitment to one another. At this point in time, there are very few published outcome studies of programs explicitly conceived to help build coparenting alliances in such families. This article reviews what we currently know from this evolving field of study, and from those related responsible fatherhood and marriage and relationship enhancement (MRE) initiatives that included any explicit targeting, strengthening, and assessment of fragile family coparenting in their designs. We summarize lessons learned thus far from Access and Visitation (AV) programs for non‐residential fathers, from MRE programs for low‐income, unmarried couples, and from newer programs for fragile families directly designed to target and support coparenting per se. We close with recommendations for charting this important new family process terrain.     

Cooperation,Conflict, or Disengagement? Coparenting Styles and Father Involvement in Fragile Families

This paper draws on information from the Fragile Families Study (N = 2,695) to examine how different coparenting styles emerge and are related to fathers' involvement with young children in a representative sample of unmarried parents. The results show that the quantity and quality of paternal involvement is significantly higher when unmarried parents establish a cooperative as opposed to a disengaged or conflicted coparenting style. Cooperative coparenting is less likely, however, when unmarried parents have separated after the birth or were never together as a couple, when fathers are unemployed or have other risk factors, when the child has a more difficult temperament, and when parents have fewer children together. This analysis also helps clarify previously equivocal findings concerning the relationship between coparenting conflict and paternal involvement. Regression results show that paternal involvement is not significantly different among parents with cooperative and mixed coparenting styles, indicating that when unmarried parents can work together and support each other's parenting efforts, even if they argue frequently while doing so, fathers remain more involved. At the same time, conflicted coparenting leads to a larger decrease in father involvement than disengaged coparenting. In the context of poorer‐quality coparenting relationships, it was conflict that mattered for fathering, not just parents' inability to cooperate. Implications of these findings for parenting education programs are discussed.     

Sorting the Liars from the Truth Tellers: The Benefits of Asking Unanticipated Questions on Lie Detection

We examined the effect of asking unanticipated interview questions on lie detection. We set up a room in which truth tellers (N = 40) performed five tasks. Liars (N = 40) observed the activity room through a window and were asked to generate a story in which they claim to have performed five tasks. The interview schedule included four thematically related pairs of questions. The first question of each pairing was easy for interviewees to anticipate, as it reflected how events are typically recalled. However, the second included a perspective shift (temporal or spatial), which made the question harder to anticipate. We also measured cognitive load via performance on an object sorting secondary task that interviewees undertook during interview. Compared with truth tellers, liars' verbal responses showed a greater decline in details across three out of four question pairs. Liars also sorted significantly fewer objects per minute on the secondary task. Copyright © 2012 John Wiley & Sons, Ltd.     

Correlates of Parenting on a Neonatal Intensive Care Unit: Maternal Characteristics and Family Resources

The association of maternal characteristics, family resources, and receipt of prenatal care with parenting behaviors observed in a neonatal intensive care unit (NICU; n = 383) was assessed. The parenting behavior of mothers not receiving prenatal care (n = 128) was compared to that of mothers of the preceding and subsequent admissions (n = 256) by retrospective chart review. Parenting variables included frequency of visits to the NICU and evaluative ratings of parents' involvement with their infant. Parenting of the no-prenatal-care group was significantly less favorable than the control on all comparisons. Factor analysis supported a priori grouping of parenting variables. A stepwise multiple regression of maternal and family characteristics to the factor-derived variable, parenting, showed significant contributions for prenatal drug use and father involvement. Pediatric interventions assessing maternal social and behavioral characteristics are proposed.     

The Geometry of Enhancement in Multiple Regression

In linear multiple regression, “enhancement” is said to occur when R ²=b′r>r′r, where b is a p×1 vector of standardized regression coefficients and r is a p×1 vector of correlations between a criterion y and a set of standardized regressors, x. When p=1 then b≡r and enhancement cannot occur. When p=2, for all full-rank R _xx≠I, R _xx=E[xx′]=V Λ V′ (where V Λ V′ denotes the eigen decomposition of R _xx; λ ₁>λ ₂), the set B₁:={b_i:R²=b_i￠r_i=r_i￠r_i;0 < R² ￡ 1}\boldsymbol{B}_{1}:=\{\boldsymbol{b}_{i}:R^{2}=\boldsymbol{b}_{i}'\boldsymbol{r}_{i}=\boldsymbol{r}_{i}'\boldsymbol{r}_{i};0R² ￡ 1;R²l_p ￡ r_i￠r_i < R²}0p≥3 (and λ ₁>λ ₂>⋯>λ _p ), both sets contain an uncountably infinite number of vectors. Geometrical arguments demonstrate that B ₁ occurs at the intersection of two hyper-ellipsoids in ℝ ^p . Equations are provided for populating the sets B ₁ and B ₂ and for demonstrating that maximum enhancement occurs when b is collinear with the eigenvector that is associated with λ _p (the smallest eigenvalue of the predictor correlation matrix). These equations are used to illustrate the logic and the underlying geometry of enhancement in population, multiple-regression models. R code for simulating population regression models that exhibit enhancement of any degree and any number of predictors is included in Appendices A and B.     

Do eating disorder voice characteristics predict treatment outcomes in anorexia nervosa? A pilot study

Individuals with anorexia nervosa often describe experiencing an internal “voice” of their disorder, which previous research has associated with multiple dimensions of eating pathology. This pilot study examined whether eating disorder measures use invoice characteristics at the outset of outpatient therapy predicted changes in disordered eating over the course of treatment. Participants were 14 individuals meeting ICD-10 criteria for anorexia nervosa. Participants completed measures relating to the severity of disordered eating and voice-related characteristics (perceived voice power and metacognitive appraisals about its nature) at the start and end of therapy. Results indicated that the perceived power of the eating disorder was reduced over the course of outpatient therapy, although its other characteristics remained stable. Greater levels of voice power, omnipotence and benevolence at the outset of therapy were related to greater improvements in eating attitudes. No voice-related characteristics were associated with changes in weight. These findings suggest that voice-related appraisals do not obstruct the effectiveness of outpatient therapies for anorexia nervosa. Further studies are needed to ratify these preliminary findings.
