Examination of MMPI–2–RF Substantive Scales as Indicators of Acute Suicidal Affective Disturbance Components

A new suicide-specific diagnostic entity, acute suicidal affective disturbance (ASAD), was recently proposed to fill a void in the nomenclature. Although several studies have examined the reliability, validity, and potential clinical utility of ASAD, no studies have examined personality indicators of ASAD. This study sought to examine the association between personality and psychopathology factors, as assessed by the Minnesota Multiphasic Personality Inventory–2–Revised Form (MMPI–2–RF), and constructs that comprise ASAD in a sample of 554 psychiatric outpatients who completed all measures prior to their intake appointments. A smaller subset of patients (N = 58) also completed a measure designed to assess lifetime ASAD symptoms. Results indicated that ASAD symptoms were associated with traits characterized by emotional turmoil and atypical cognitive processes. Further, suicide-related criteria that comprise ASAD were related to low positive emotionality and hopelessness, whereas the overarousal criteria were associated with somatic symptoms and an inability to tolerate frustration and stress. These findings expand on previous research that examines the convergent and discriminant validity of ASAD and could inform clinical treatment by providing insight into personality traits that might be associated with acute suicide risk.     

Bipedal Hopping Reveals Evidence of Advanced Neuromuscular Aging Among People With Mild Multiple Sclerosis

Measures of walking such as the timed 25-ft walk test (T25FWT) may not be able to detect subtle impairment in lower limb function among people with multiple sclerosis (MS). We examined bipedal hopping to determine to what extent people with mild (Expanded Disease Severity Scale ≤ 3.5) MS (n = 13) would differ compared to age-, gender-, and education-matched controls (n = 9) and elderly participants (n = 13; ≥ 70 years old). We estimated lower limb power (e.g., hop length, velocity), consistency (e.g., variability of hop length, time), and symmetry (ratio of left to right foot). Participants completed the T25FWT and, after a rest, they then hopped using both feet 4 times along the walkway. We found that although all groups scored below the 6 -s cutoff for T25FWT, the elderly group had significantly shorter hop lengths, more variability, and more asymmetry than the controls. The results of the MS group were not significantly different from the elderly or controls in most measures and most of their values fell between the control and elderly groups. Hop length, but not measures of walking predicted Expanded Disease Severity Scale score (R² = .38, p = .02). Bipedal hopping is a potentially useful measure of lower limb neuromuscular performance.     

Replacing the Moral Foundations: An Evolutionary‐Coalitional Theory of Liberal‐Conservative Differences

Moral Foundations Theory (MFT) explains liberal‐conservative differences as arising from different moral intuitions, with liberals endorsing “individualizing” foundations (Harm and Fairness) and conservatives also endorsing “binding” foundations (Authority, Respect, and Purity). We argue these labels misconstrue ideological differences and propose Evolutionary‐Coalitional Theory (ECT) as an alternative, explaining how competitive dynamics in the ancestral social environment could produce the observed ideological differences. We test ECT against MFT across three studies. Study 1 shows the so‐called “binding” orientation entails the threat‐sensitivity and outgroup antagonism predicted by ECT; that is, an authoritarian motive. Similarly, Study 2 shows the so‐called “individualizing” orientation is better described as a universalizing motive, one reflecting a broader set of moral commitments (e.g., to nature) and a broader sociality than the egocentrism implied by MFT. Study 3 provides a factor analysis reducing “binding” to authoritarianism and “individualizing” to universalism, with the latter loading against social dominance orientation (SDO). A hierarchical regression then provides additional evidence for ECT, showing this dominating motive (SDO) accounts for variance in conservatism that MFT leaves unexplained. Collectively, these three studies suggest that ECT offers a more accurate and precise explanation of the key psychological differences between liberals and conservatives.     

Determinants of depressive mood states in everyday life: An experience sampling study

This study tests relative contributions and time-course of proposed risk/protective factors (e.g., stress, coping, and lack of social interactions) for influencing depressed mood states in daily life. Seventy-three participants completed baseline measurement of major depressive disorder symptomatology, followed by smartphone app-based monitoring of momentary experiences of depressed mood and risk/protective factors for 7 days. All predictors had deteriorating impacts on mood as lag increased, and the optimal lag appears to be less than 120 min. Linear decay in effect sizes was found for physical activity, social interaction, and tiredness, whereas exponential decline in effect sizes was found for stress and coping ability. Stress, coping, and depressed mood at the prior time-point were the best predictors of subsequent mood. These effects did not differ as a function of trait depressive symptom severity. Findings highlight the influence of spacing of assessments in identification and magnitude of predictors of mood states, and provide insights into key drivers of change in mood and their time-course.     

Counterfactual discrimination

In counterfactual cases of discrimination, an agent would have treated someone worse had circumstances been different such that instead of being a member of her actual group, she was a member of some other group. The case for considering such cases to be genuine cases of discrimination is bolstered by the fact that we are inclined to say that cases where an agent would have treated someone better had she been a member of another group are discriminatory. But I argue that the cases are relevantly different: in one kind of case, but not the other, a person is harmed. I then consider and reject a number of objections to this suggestion.     

Of Tooth and Claw: Predator Self-Identifications Mediate Gender Differences in Interpersonal Arrogance

Men often score higher than women do on traits or tendencies marked by hostile dominance. The purpose of the present research was to contribute to an understanding of these gender differences. Four studies (total N?=?494 U.S. undergraduates) administered a modified animal preference test in which participants could choose to be predator or prey animals, but not labeled as such. Men were consistently more interested in being predator animals than women were, displaying a sort of hostile dominance in their projective preferences. Predator self-identifications, in turn, mediated gender differences in outcomes related to hostile dominance. Studies 1 and 2 provided initial evidence for this model in the context of variations in interpersonal arrogance, and Studies 3 and 4 extended the model to nonverbal displays and daily life prosociality, respectively. The findings indicate that gender differences in hostile dominance are paralleled by gender differences in preferring to think about the self in predator-like terms. Accordingly, the findings provide new insights into aggressive forms of masculine behavior.     

Rationalist restrictions and external reasons

Historically, the most persuasive argument against external reasons proceeds through a rationalist restriction: For all agents A, and all actions Φ, there is a reason for A to Φ only if Φing is rationally accessible from A’s actual motivational states. Here I distinguish conceptions of rationality, show which one the internalist must rely on to argue against external reasons, and argue that a rationalist restriction that features that conception of rationality is extremely implausible. Other conceptions of rationality can render the restriction true, but then the restriction simply fails to rule out external reasons.     

Testing a bilinear domain-specific model of acculturation and enculturation across generational status

This study attempted to replicate Miller's (2007) finding that a bilinear domain-specific model of Asian American acculturation demonstrated superior model fit when compared to unilinear and bilinear domain-generic models. Current confirmatory factor analytic tests of competing acculturation models in a cross-validation sample of 306 participants were consistent with Miller's findings. In addition, this study provided novel findings regarding the nature of the acculturation process by testing the bilinear domain-specific model across 1st and 2nd generation samples. Specifically, the generational status moderator hypothesis-that a unilinear model of acculturation would be most appropriate for 1st generation individuals and a bilinear model of acculturation would be most appropriate for 2nd generation individuals-was tested with 494 1st and 2nd generation Asian Americans. Contrary to the assumptions of the generational status moderator hypothesis, present findings demonstrated the appropriateness of the bilinear domain-specific model for both 1st and 2nd generation Asian Americans. Present findings also revealed a pattern of shared and unique relationships between cultural orientations and acculturation domains across generations. Implications for research and counseling are explored.     

A Reflection on Our Freedom

Imagine a deterministic world with plane-symmetry. Beings near this plane might well mistake it for a mirror. When they realize their error, they might be apt to relinquish even stronglyheld commitments to views about the compatibility of freedom and determinism. The following account reports such reflections.     

United we stand: Intergroup conflict moderates the intergroup sensitivity effect

Ingroup members who criticize their group face much less resistance than outgroup members who say the same thing (the intergroup sensitivity effect). In the context of intergroup conflict, however, it was predicted that treatment of ingroup critics would not be so generous. Muslim Indonesians read an extract from an interview in which the speaker criticized Muslims. The comments were attributed to either another Muslim or to a Christian. Before reading the criticism, half of the participants had read an article describing intense conflict between Muslims and Christians in Indonesia, whereas the other half read a neutral article. As predicted, negativity toward the ingroup critic and the ingroup critic's comments increased in the conflict salience condition, to the point that the intergroup sensitivity effect disappeared. However, conflict salience did not have an effect on attributions of motive or on agreement with the message. Implications for our understanding of “patriotic criticism” are discussed.
