The relationships between functional and dysfunctional impulsivity and aggression across different samples

E. S. Barratt proposed the term impulsive aggression to define a kind of aggression that is characterized by acting without thinking because of high levels of impulsivity. Previous research using psychometric measures has shown that impulsivity and aggression are related as far as psychometric measures are concerned. Nevertheless, most of the research has been done with samples of university students. Our research tests whether this relationship is stable across different samples; university students, teenagers and workers. Our results show that impulsivity and aggression have a consistent pattern of relationships across these samples, with impulsivity being specially related to emotional and instrumental aspects of aggression. Furthermore, the effects of anger on aggression seem to show a pattern of relationship that depends on age, with a tendency to physical aggression in young people and verbal aggression in adults.

Sex Differences in the Full and Reduced Versions of the Aggression Questionnaire

Sex differences in aggression have been widely analyzed using the Buss and Perry (1992) aggression questionnaire (AQ). The sex effects obtained when this questionnaire has been shortened and refined indicate some difficulties in replicating the results obtained with the full questionnaire. The present paper attempts to analyze whether these difficulties indicate sex bias in the AQ. To this end we administered the AQ to a sample of 416 subjects and analyzed the possible sex bias of the AQ by using confirmatory factor analysis models. Results show that the AQ is free of sex bias and that sex differences in the AQ and in the two revised versions seem to be the result of true sex differences and are specific to the physical aggression scale.

Are old people so gentle? Functional and dysfunctional impulsivity in the elderly

BACKGROUND Although old people may seem less impulsive than adults, numerous experimental studies report that they have inhibitory deficits. Bearing in mind that there is a relationship between inhibition processes and impulsivity, age-related inhibition deficits suggest that older people could be more impulsive than adults. METHODS The aim of the current study was to compare the functional and dysfunctional impulsivity scores obtained in a sample of elderly people (65 years old and above) with those obtained in previous studies on samples of adolescents and adults. Dickmans Impulsivity Inventory was administered to 190 individuals aged between 65 and 94 years without dementia or cognitive impairment. RESULTS Results indicated that the elderly sample showed higher dysfunctional impulsivity levels than the adult samples, which is consistent with the inhibition deficits mentioned above. There were no significant differences in functional impulsivity. Furthermore, old women had higher scores than old men on dysfunctional impulsivity. CONCLUSIONS This study provides evidence of age-related changes in dysfunctional impulsivity. Functional impulsivity did not show the same pattern as dysfunctional impulsivity, being quite stable across the age span. it seems, then, that impulsivity cannot be considered to decrease with age and dysfunctional impulsivity may even increase.

How social desirability and acquiescence affect the age-personality relationship.

BACKGROUND Recent studies have suggested that the age-personality relationship may be partially explained by age-related changes in social desirability. In the present study, we analyze how age affects social desirability and acquiescence, and how they affect the age-personality relationship. METHOD We used a specially designed personality test, which provides response bias and personality dimension scores independently of each other. We applied this test to a sample of 3773 individuals aged between 13 and 97 years old (49.69% female) and analyzed the effects of age, sex, and their interactions on response bias and personality dimensions. RESULTS Age affects social desirability and acquiescence, both of which increase with age, and this increase affects the age-personality relationship, especially for dimensions such as Agreeableness or Conscientiousness. CONCLUSIONS The age-related differences found in self-reported personality measures might be partly attributable to age-related increases in response bias. Furthermore, the high scores of elderly people on response bias measures implies that the results of self-reports that do not incorporate any correction for response bias should be viewed with caution, especially when they are obtained in samples of people over 50 years old.

I-DAQ: a new test to assess direct and indirect aggression free of response bias.

Self-reports of aggression are deeply impacted by response bias, especially by social desirability, but there are no specific methods for controlling this bias. Furthermore, despite the importance of the subject few instruments have been designed to assess both direct and indirect forms of aggression. The aim of the present research was to develop a brief measure that comprises both forms of aggression and which makes it possible to obtain scores free of social desirability and acquiescence effects. The scales were created using recently developed methods for controlling response bias effects in a sample of 750 participants over a wide age range. The items were chosen by a panel of judges from among the best of the existing aggression measures. Confirmatory factor analysis showed the expected three factor structure (CFI = .98; AGFI = .97 and RSMEA = .078, 90% C.I. = .074 - .083) and the scales showed good psychometric properties in that they had good reliability (ranging from θxx = .77 to θxx = .83), and convergent and criterion validity.

Values in a Cross-Cultural Triangle: A Comparison of Value Taxonomies in the Netherlands, Austria, and Spain

This study aimed at finding the kernel structure common to three different value taxonomies in European languages (Dutch with 641 values and 634 participants, Austrian with 496 values and 456 participants, and Spanish with 566 values and 532 participants). Values from those three taxonomies were translated into English, thus forming the basis for the connections between the taxonomies. Using the common values between the three pairs of languages, factor structures resulting from a principal components analysis (PCA) were pairwise compared based on congruence coefficients after Procrustes rotation. Moreover, PCA was applied to a set of 139 values that was common to the three taxonomies. Furthermore, a joint matrix of values was formed with 1,703 values and 1,622 participants. Using only the common values after translation into English, this matrix was compressed to a set with 413 values and 1,622 participants, which was subjected to simultaneous components analysis (SCA). The different procedures ultimately led to a common structure with five value components, each specified in four facets. Those value components are Interpersonal Relatedness, Status and Respect, Commitment and Tradition, Competence, and Autonomy.

The effects of ageing on self-reported aggression measures are partly explained by response bias.

BACKGROUND Recent studies have suggested that the age-personality relationship may be partly explained by age-related changes in response bias. In the present study, we analysed how age affected social desirability and acquiescence, and how this effect impacted the age-aggression relationship. METHOD We used the Indirect-Direct Aggression Questionnaire, which provides response bias and physical, verbal and indirect aggression scores independently of each other. We applied this test to a sample of 616 individuals aged between 18 and 96 (M = 49.24, SD = 24.81) and analysed the relationships between age and aggression measures with and without response bias. RESULTS We found that social desirability and acquiescence increased by between one and two standard deviations between adulthood and old age. This affected the age-aggression relationship for all aggression scales and, especially for verbal and indirect aggression, whose relationships with age decreased from r = -.192 and r = -.309 to r = .012 and r = -.159, respectively, when response biases were controlled. CONCLUSIONS When response bias and, in particular social desirability, are not controlled, elderly people tend to show aggression scores that are considerably lower than their true aggression levels.

The role of psychological maturity in direct and indirect aggressiveness in Spanish adolescents.

Understanding which factors are related to different kinds of aggressive behaviors in adolescents might help to improve violence-prevention programs for schools and families. Although some studies show that adolescents who are less psychologically mature tend to display more behavioral problems, few studies have been performed on the relationship between aggressive behavior and psychological maturity in adolescence, and no studies have focused specifically on indirect aggression. For this reason, the current research tests the role of psychological maturity in direct and indirect aggressiveness in a sample of 193 Spanish adolescents (49% boys and 51% girls) between 14 and 18 years old (M = 16.1, SD = 1.18). The results show that psychological maturity is related to both kinds of aggressiveness. In fact, less mature adolescents tend to show higher levels of direct aggression (r = -.22, p < .01) and indirect aggression (r = -.44, p < .01). More specifically, the dimensions of psychological maturity most related to aggressiveness are self-reliance and identity: self-reliance is the main predictor of indirect aggression (p < .01) and identity is the main predictor of direct aggression (p < .01). Moreover, overall psychological maturity is more related to indirect aggression in men than in women (p < .05), so the increase in psychological maturity implies a greater decrease of indirect aggression in men.

Assessing and Controlling Acquiescent Responding When Acquiescence and Content Are Related: A Comprehensive Factor-Analytic Approach

This article proposes procedures for assessing and controlling acquiescence in personality scales when acquiescence is related to the content that the scale intends to measure. Our proposal is comprehensive in that it can be applied to different item response formats fitted with response models that can be parameterized as factor-analytic models. In the calibration stage, our proposal makes joint use of a balanced scale and a set of markers for acquiescence, and consists of 2 sequential procedures: a direct semirestricted solution, and a restricted solution with minimal identification constraints. In the scoring stage, we discuss how the information given by the acquiescence–content relation can be used to obtain Bayes expected a posteriori scores. The robustness of the direct procedure is assessed both analytically and by simulation. A free, user-friendly program that implements the procedures proposed is made available. Practical issues of use and interpretation are discussed and illustrated with an empirical application.

Psycho-Lexically Based Virtue Factors in Spain and Their Relation With Personality Traits

ABSTRACT. The psycho-lexical approach was used to identify virtues in a Spanish population. A total of 209 descriptors were identified as virtues and administered to 485 participants, who were instructed to indicate the extent to which each virtue term applied to them. Principal Components Analysis revealed seven factors: Self-confidence, Reflection, Serenity, Rectitude, Perseverance & Effort, Compassion, and Sociability. The results showed that there was no simple one-to-one correspondence between these factors and those obtained in previous studies. However, the results are congruent with those obtained in other studies as far as the relation between virtues and personality traits is concerned.
