Virtue rewarded: reinforcement and punishment in an acute psychiatric admission ward.

This study evaluated the naturally occurring behaviour of psychiatric patients in an acute psychiatric setting. Direct behavioural observations were carried out to determine the amount of time patients spent in interaction, with whom they interacted, and the nature of the interaction. Also examined were each respondent group's type and rate of interactive behavior. For much of the time no interactive behaviour was observed to occur, but much of the behaviour exhibited by patients was socially appropriate. When social interactions did occur, both fellow patients and staff tended to reinforce appropriate behaviour. However, nurses reinforced inappropriate crazy behaviour much less than did fellow-patients or non-nursing staff. Treatment implications are discussed.

Patient interactions in four psychiatric wards.

This article describes the interactions between patients and between patients and staff in 4 psychiatric wards. Two of the wards are acute admission units and 2 are for long-stay chronic patients. The hospital is diagnostically streamed so that not only does the average length of stay vary between wards but so, for one ward, does the predominant diagnostic group. Patient interactions were analysed in terms of 5 major interactional categories: individual verbal, individual nonverbal, group verbal, group nonverbal and physical. The results show that, although there was little change in the overall level of verbal interaction as a function of chronicity, there were large shifts in patient-patient and staff-patient interaction rates. Variations between the 4 wards on the 4 other interactional categories are explained in terms of the known diagnostic characteristics of the patients.

A quantitative study of nursing staff interactions in psychiatric wards.

Data from 2 studies investigating staff-patient and staff-staff interaction rates are presented. In the first the staff-patient ratio was varied by holding patient numbers constant and systematically varying staffing levels. The results showed that although the percentage of time nurses spent interacting with patients did not change, staff-staff interaction increased as a function of increased staffing levels. In the second study the interaction rates from 4 wards were combined. These data showed that, as in the first study, staff-patient interaction remained constant, as staff numbers increased, whilst staff-staff interaction increased. However, unlike the first study, when analysed in terms of the staff-patient ratio, both categories of interaction increased as the staff-patient ratio increased.

Evaluation of a residential behavioral program for behaviorally disturbed, mentally retarded young adults.

The Adaptive Behavior Scale (ABS) was used to evaluate a three-level token economy designed to modify some aspects of the behavior of behaviorally disturbed young adults of borderline intelligence. The ABS was administered to all those referred to the program. Those admitted were retested upon discharge and 6 months later. Those not admitted, or rejected, were retested 12 months later. Results showed that initially there were few significant differences in scores between the accepted and rejected groups. Following treatment, however, large improvements occurred in those areas that were logically related to target behaviors within the token economy. These gains were maintained on follow-up. The rejected group showed no improvements over the same period.

Head-position training through biofeedback: prosthetic or cure?

This report investigates the effectiveness of biofeedback in the treatment of poor head-positioning in patients with cerebral palsy. Four patients were given feedback of head-position trainer: two were given 20 sessions, the other two were given 10 sessions followed by 10 sessions of social reinforcement. It was found that biofeedback produced significant changes in head control during therapy but that these did not transfer well to other situations, nor did it result in long-term positive improvement. The use of social reinforcement produced excellent and long-term gains. These results are discussed in terms of stimulus properties and reinforcement conditions. General implications of this study in relation to the generalisation and maintenance of behaviour change are also discussed.
