Aging, inhibition, and social inappropriateness

This study explores the hypothesis that age-related declines in inhibitory ability are associated with increases in socially inappropriate behavior. Consistent with this hypothesis, older participants were less likely than younger participants to differentiate between public and private settings when inquiring about potentially embarrassing issues, according to their peers. Additionally, this indiscriminate public inquiry was associated with decreased closeness with participants' peers, particularly for older adults. Finally, this age-related increase in social inappropriateness was mediated by inhibitory deficits associated with aging. These results suggest that age-related deficits in inhibitory ability may cause people to become socially inappropriate against their will.

Further psychometric study of the Beck Anxiety Inventory including factorial analysis and social anxiety disorder screening

Objective. To analyze the psychometric properties of the Brazilian Portuguese version of the Beck Anxiety Inventory (BAI) in terms of its internal consistency, scores distribution, concurrent and discriminant validity, and factorial analysis in a sample of university students and social anxiety disorder (SAD) cases and non-cases. Methods. A sample of Brazilian university students from the general population (N = 2314) and a sample of university students identified as cases (N = 88) and non-cases (N = 90) of SAD were assessed, using as a parameter the Structured Clinical Interview for the DSM-IV. The different instruments were completed individually in the presence of an experienced rater. Results. The BAI showed adequate internal consistency (0.88-0.92) and discriminant validity, with 0.74 sensitivity and 0.71 specificity for a cut-off score of 10. The factorial analysis suggested a three-factor solution to be the most adequate. Conclusions. The version of the BAI studied is quite adequate to be used in the context of Brazilian university students, identifying the presence of anxiety indicators. However, its usefulness to screen for SAD seems limited.
