The association between social withdrawal and internalizing problems of children

Children identified as low-frequency interactors or socially withdrawn were compared to outgoing children to evaluate whether socially withdrawn children display concurrent internalizing problems. From a sample of 640 children in grades 2-5, 48 children were identified by teachers as low-frequency interactors and 72 children were selected as outgoing or sociable. When these two groups were compared on a battery of teacher, peer, and self-report measures that assessed internalizing difficulties, the low-frequency interactors were found to display concurrent problems in adjustment. Children who rarely interacted with peers were less well liked by their peers, displayed poorer self-concepts, and were more depressed and anxious than sociable children. In contrast to these findings regarding internalizing problems, the two groups did not differ on measures of externalizing problems. The results lend support to the concurrent validity of the low-interaction method of identifying socially withdrawn children.

Impact of a Brief Intervention on Patient Anxiety Prior to Day Surgery

Patients anticipating surgical procedures experience significant anxiety, resulting in adverse outcomes and increased expenditures. Research has investigated the impact of anxiety-reducing interventions, frequently the provision of surgical information, with inconsistent results. The present study (N = 98) examined preference for information, or monitor-blunter coping style, and the impact of a pre-surgical phone call from an anesthesiologist on anxiety in which treatment group participants (n = 51) dictated the amount of information received. Monitors were hypothesized to desire more information than blunters, and changes in anxiety for monitors/blunters were hypothesized to be moderated by length of call. Monitors and blunters demonstrated equal call durations and anxiety levels remained equivalent across groups. Findings and implications for future research are discussed.     

Methylphenidate slows reactions of children with attention deficit disorder during and after an error

A Sternberg memory search task was administered under placebo and methylphenidate to 42 children with cross-situational attention deficit disorder (ADD), 31 children with cross-situational ADD plus oppositional features, and 25 patients with marginal ADD. Overall, stimulant medication enhanced accuracy and speed. In addition, patients reacted faster on correct responses not preceded by an error than on errors (especially false alarms) or on correct responses following an error. The slowness during error reactions may reflect decreased confidence or confusion during stimulus classification. This uncertainty may also lead subjects to respond with greater caution, hence more slowly, on correct responses following errors. Notably, methylphenidate increased the slowing of reactions on error trials as well as on correct reactions following an error. Stimulant medication may augment subjects' persistence when they are uncertain or confused, thereby heightening caution and promoting accuracy on succeeding trials. Consistent with previous reports of the generality of enhancement of performance by stimulant medication, the impact of methylphenidate was comparable for the three subtypes of ADD studied.Jaine Strauss is at Macalester College.This research was supported by National Institute of Mental Health Grants MH32103 and MH38118.

Simulation of motor-neuronal networks

This research develops a theoretical connectionist-type model of the operation of the human motor system. The model includes the operation of the cerebral cortex, pons, spinal cord, and muscles. It emphasizes the parallel passage of neuronal signals, the integration of multiple signals within nuclei, and the modulation of signals as a result of sensory input. A redundant Fast Fourier Transform (FFT) procedure that analyzes EEG signals by a method similar to the one used by pontine nuclei is described.     

The relationship of sexual adjustment and related sexual behaviors and attitudes to marital adjustment

Abstract

This paper examines the extent of relationship between sexual adjustment and marital adjustment for 30 married couples followed for 3–6 months. Sexual adjustment was assessed by means of the LoPiccolo-Steger Sexual Interaction Inventory, and two other measures termed a Couple Interaction Scale (CI) and a Couple Compatibility Ratio (CCR). Marital adjustment was assessed by means of the Locke-Wallace Marital Adjustment Scale (L-W MAS) and a clinically-devised instrument based on the extent of support between the marital partners. The two marital adjustment instruments agreed closely. A high degree of association was obtained between most of the sexual adjustment measures and the two marital adjustment measures; using the most reliable of these measures, it is estimated that sexual adjustment contributed between 40 % and 55 % of the variance in marital adjustment. This association was not due to a specific stage of. the human sexual response cycle of desire, excitement, orgasm and gratification. Intercorrelation of measures of each of these stages with the marital adjustment measures generally yielded significant relationships.     

Changes of attachment status among women with personality disorders undergoing inpatient treatment

Background: Attachment has increasingly received attention in psychotherapy and has been used as a predictor of process and outcome. Studies investigating changes of attachment styles during psychotherapy are very rare. Method: Forty women with either borderline (BPD) or avoidant personality disorders (AVPD), treated as inpatients, were investigated using an attachment interview (interpersonal relations assessment (IRA)), and questionnaires to determine therapy outcome at the beginning and after seven weeks of therapy. The IRA uses similar questions as the adult attachment interview (AAI) and is used as the basis for the adult attachment prototype rating (AAPR), a procedure to assign individuals to prototypical categories of attachment. Results: The study showed that the therapy in general was effective. In contrast to other studies, we did not find many women classified as secure at the end of their therapy. Comparisons of pre‐post‐ratings revealed instead that clients within both subgroups received higher ratings for the avoidant prototypes at the end of therapy, indicating deactivation of attachment. Changes from ambivalent to avoidant attachment were linked with better outcome among women with borderline personality disorder (BPD). Conclusions: This study adds further evidence to the result that attachment styles do not change dramatically during a time‐limited psychological treatment of personality disorder. Instead, the study showed that features of preoccupied/ambivalent attachment were less significant after seven weeks of therapy. For women with BPD, these changes were linked with a more favourable outcome which might reflect a more structured and deactivated attachment status as a result of inpatient therapy.
