Habituation at home

Habituation to mother's face in naturally occurring en face social interactions and to a single object in naturally occurring solitary play was studied in American and Japanese infants. Habituation was observed in both conditions in both samples, and home habituation data paralleled analogous laboratory habituation data both quantitatively and qualitatively.     

Issues in the assessment of social competence in children

Recent interest in children's social competence has been prompted by findings of correlational and retrospective studies that indicate a positive relationship between early social adjustment problems of children and their adjustment later in life. To date, the assessment methodology in the area has pursued two directions: (1) sociometric measures (peer nomination and peer rating scales), which have provided the major means of identifying the socially competent child, and (2) direct observation, principally employed in the specification of socially competent behaviors. The current uses and the inherent assets and limitations of both strategies are discussed along with suggestions for enhancing current data collection methods. Issues concerning the definition of social competence, generalizability of current findings, and social norms are also examined.     

Pharmacotherapy of schizophrenia and affective disorders: Behavioral assessment of psychiatric medications

Objectively defined, publicly observable ward behaviors (body activity, extremity activity, scanning, social interaction, proximity, participation, laughing/smiling, and idiosyncratic behavior) emitted by psychiatric inpatients with either schizophrenic or affective disorders were time sampled both before and during the administration of psychiatric medications (neuroleptics, tricyclics, and lithium). The data indicate that the primary effects of the pharmacological interventions are confined to activity measures and symptoms rather than social behaviors. The implications of these results for treatment protocols are discussed in terms of interactions between pharmacological and psychosocial interventions. In addition, rates of behavior during treatment were related to baseline rates via a log-log function of negative slope, a result that is consistent with data derived from the infrahuman laboratories. Taken together the results provide support for attempts to relate preclinical and clinical psychopharmacology and suggest that behavioral assessment can be applied profitably to drug effects in clinical situations.These investigations were supported in part by State of Illinois Department of Mental Health and Developmental Disabilities Grants RD836-13 and RD622-02 to the first author.

Measures of interobserver agreement: Calculation formulas and distribution effects

Seventeen measures of association for observer reliability (interobserver agreement) are reviewed and computational formulas are given in a common notational system. An empirical comparison of 10 of these measures is made over a range of potential reliability check results. The effects on percentage and correlational measures of occurrence frequency, error frequency, and error distribution are examined. The question of which is the best measure of interobserver agreement is discussed in terms of critical issues to be considered     

Wagering on a large scale: Relationships between public gambling and game manipulations in two state lotteries

Public wagering was examined in relation to game adjustments during the first 523 draws of Oregon's "Megabucks" lottery and the first 540 draws of Arizona's "The Pick" lottery. Oregon's lottery was modified five times during this period, and Arizona's lottery underwent four modifications. Public wagering was not related to decreases in the odds of winning in either state. Wagering increased in both states following the introduction of a minimum $1 million jackpot. Wagering also increased following a change in game frequency from weekly to semiweekly draws. Sales trends in both states suggest that over the period examined, larger jackpots were required to maintain previous levels of lottery play. These data suggest that public participation in gambling can be manipulated by state lottery commissions through adjustments in lottery contingencies.     

BEACHES: AN OBSERVATIONAL SYSTEM FOR ASSESSING CHILDREN'S EATING AND PHYSICAL ACTIVITY BEHAVIORS AND ASSOCIATED EVENTS

An integrated system for coding direct observations of children's dietary and physical activity behaviors was developed. Associated environmental events were also coded, including physical location, antecedents, and consequences. To assess the instrument's reliability and validity, 42 children, aged 4 to 8 years, were observed for 8 consecutive weeks at home and at school. Results indicated that four 60-min observations at home produced relatively stable estimates for most of the 10 dimensions. Interobserver reliabilities during live and videotaped observations were high, with the exception of “consequences” categories that occurred in less than 1% of observed intervals. Evidence of validity was provided by findings that antecedents were associated with respective dietary and physical activity behaviors. The five physical activity categories were validated by heart-rate monitoring in a second study. The Behaviors of Eating and Activity for Children's Health Evaluation System is appropriate for studying influences on diet and physical activity in children in a variety of settings.     

Giving and Receiving Help: Interpersonal Transactions in Mutual-Help Meetings and Psychosocial Adjustment of Members

The helping transactions that occur in group meetings have been theorized to be important therapeutic mechanisms within mutual-help (or self-help) groups. Hypothesized links between giving and receiving help and psychosocial adjustment were examined in a mutual-help group for individuals with serious mental illness (GROW). Participants' adjustment was assessed at two time points and helping behaviors were measured with observational coding of weekly group interactions during the period between assessments. Frequencies of helping behaviors were used to predict Time 2 adjustment after controlling for initial adjustment. Consistent with the helper therapy principle, giving help to others predicted improvements in psychosocial adjustment; giving advice was a unique predictor. Total amount of help received was not associated with adjustment, but receiving help that provided cognitive reframing was associated with better social adjustment. A predicted interaction suggested that receiving help was related to better functioning when members experienced high levels of group integration.     

The Family Environment in Chronic Pain Patients: Comparison to Controls and Relationship to Patient Functioning

Operant and cognitive-behavioral models of chronic pain have called attention to the importance of examining the marital and family environments of chronic pain patients. In this study, 50 chronic pain patients and their spouses and 33 control participants and their spouses completed measures of the family environment, marital satisfaction, and patient physical and psychological functioning. Patients' overt pain behaviors were coded from videotapes of patient–spouse interactions. Compared to controls, pain patients and their spouses rated their family environments as lower in cohesion and higher in control, and there was a trend for spouses to report more marital dissatisfaction. Chronic pain patient depression was associated negatively with patient-rated family cohesion and expressiveness and spouse-rated family organization and positively with patient-rated family conflict. Overt patient pain behaviors and spouse-rated patient disability were related negatively to spouse-rated family cohesion. Spouse marital satisfaction was associated negatively with patient depression and with spouse ratings of patient disability and pain behaviors.     

A review of observer reactivity in adult-child interactions

The present article reviews studies which have examined the question of observer reactivity in adult-child interactions. Seventeen studies were located. Studies were classified according to the paradigm used to examine reactivity, the setting in which the study was conducted, the identification of the child as a behavior problem, and the occurrence and direction (i.e., increases or decreases in the observed behavior) of reactivity. The results indicated that the awareness paradigm has been employed most frequently, the laboratory has been the primary setting utilized, and problem and nonproblem children have been employed with approximately equal frequency. Reactivity was reported in about three-fourths of the studies. For adults positive and neutral verbal and physical behaviors were more reactive than negative behaviors. The positive and neutral behaviors typically increased in the observer's presence. For children conclusions are not warranted at this time as too few studies have examined children's behavior.Preparation of this article was supported in part by NIMH Grant MH28859-01.
