TREATMENT OF PICA THROUGH MULTIPLE ANALYSES OF ITS REINFORCING FUNCTIONS

We conducted functional analyses of the pica of 3 participants. The pica of 1 participant appeared to be maintained by automatic reinforcement; that of the other 2 participants appeared to be multiply controlled by social and automatic reinforcement. Subsequent preference and treatment analyses were used to identify stimuli that would compete with the automatic function of pica for the 3 participants. These analyses also identified the specific aspect of oral stimulation that served as automatic reinforcement for 2 of the participants. In addition, functional analysis-based treatments were used to address the socially motivated components of 2 of the participants' pica. Results are discussed in terms of (a) the importance of using the results of functional analyses to develop treatments for pica and (b) the advantages of developing indirect analyses to identify specific sources of reinforcement for automatically reinforced behavior.     

Psychometric properties and standardised data for questionnaires measuring negative affect, dispositional style and daily hassles. A nation-wide sample

Within the behavioral field, self-report inventories measuring emotional condition from a state/trait perspective are in frequent use. Some of these measures have insufficient standardisation and/or are out of date. In order to upgrade some of the frequently used self-report inventories a nation-wide survey ( N =2500) was performed. Measures of negative affect (state-anxiety STAI-S , trait-anger STAS-T ), and depression ( CES-D ), dispositional style ( LOT ) and daily hassles ( DH ) were examined. Psychometric data and demographic differences for all the inventories used are presented. The reliability measures for the scales show high consistency, ranging from 0.76 to 0.95 (Cronbach's alpha). The overall results indicate that females are more hassled, depressed, anxious, hostile, and have a more negative dispositional style than males. These results are most pronounced among younger females.     

Predictions of developmental patterns during infancy: Assessments of children 0–1 years

The present study investigated how neonatal behavioural organization was related to later mental development during the first year of life. The study further investigated the relationship between early social affective behaviour and later mental development. A group of 40 infants was assessed five times during the infants' first year, at three and 14 days and at four, eight and 12 months. The Brazelton Neonatal Behavioural Assessment Scale (NBAS), the Duve method (a clinically based method for observation of social affective behaviour), and Griffiths' Mental Development Scales were used to assess the development of the infants. The results indicate that early predictive behavioural components can be identified. Neonatal state control capacity was related to motor development at both eight and 12 months. Social responsitivity at four months was related to hearing and speech at eight as well as at 12 months. The NBAS dimensions were good predictors of eight months performance, but were poor predictors of 12 months performance.
