Recent developments in family behavioral marital therapy

This paper reviews recent developments in the area of behavioral marital therapy (BMT). New information is summarized regarding the long-term efficacy of BMT and the identification of predictors of positive response to treatment and to relapse. Finally, new applications of BMT techniques are reviewed (e.g., spouse-involved therapies as the sole treatment for presenting problems in which marital distress is not the primary focus such as anxiety and affective disorders).     

Choice and foraging: the effects of accessibility on acceptability.

Pigeons responded in a successive-encounters choice procedure in which accessibility of the less profitable of two outcomes varied either in terms of probability of encounter or search time to encounter (keeping search time to the more profitable outcome constant). When the less profitable outcome was made more probable its acceptance became more likely. However, when search time to encounter the less profitable outcome was shortened, its acceptance became less likely. Both results are consistent with the delay-reduction hypothesis and with an optimality model developed for application to the successive-encounters choice procedure.     

The role of intuition in family research: Three issues of ethics

The thesis of this chapter is that, unless one has had brain-surgery, a stroke, or has some organic deficiency, we are all whole-brained people, therapists and researchers alike. To elaborate on this point, this article is focused on the role of intuition in family research. Ethical issues in family research are viewed as similar to those in symbolic experiential family therapy. Three ethical issues, counter-transference, mutual benefit, and discovery, are discussed.Appreciation is expressed to the University of Minnesota Agriculture Experiment Station for their support of this work.     

The role of cognition and coping in health behavior outcomes of asthmatic patients

This study investigates the meaning of cognitions and coping in well-being, hospital admissions, medication consumption, and absence from work due to asthma in asthmatic patients. Patients completed five questionnaires: the Respiratory Illness Opinion Survey (Kinsman, Jones, Matus, & Schum, 1976), measuring external control, psychological stigma, and optimism; the Asthma Coping Questionnaire (Maes, Schl?sser, & Vromans, 1986), measuring coping mechanisms; the Dutch version of the STAI (van der Ploeg, Defares, & Spielberger, 1979), measuring state and trait anxiety; the Questionnaire for Inner Well-Being (Hermans & Tak-van de Ven, 1973), measuring well-being; and the General Questionnaire for Asthmatic Patients (Maes et al., 1986) measuring medical outcome. Stepwise multiple regression showed that cognitions and coping determined a considerable part of the variance in the dependent variables: well-being, hospital admissions, and absence from work due to asthma.     

Determinants of seeking timely and necessary pediatric care

Ninety mothers were interviewed in a pediatrician’s waiting room about their reasons for seeking care. We compared their answers, and the pediatrician’s judgment of the visit’s necessity and timeliness to a model which distinguishes appraisal, illness, and utilization stages in seeking medical treatment. Clearly defined symptoms and the use of few home treatments predicted a more rapid assessment that one’s child was ill. No factors predicted how quickly a mother would decide that her child needed professional care, nor how rapidly she would then seek that care. The pediatrician judged visits to be necessary when the child had many physical symptoms, pain, and/or fever, and when the child’s mother was employed. He judged visits to be delayed for mothers who reported that cost of treatment may influence their decisions to seek care. He indicated that only 39% of the visits were both necessary and on time. We discuss ways to encourage appropriate utilization of pediatric visits.     

Effectiveness and persistence of precurrent mediating behavior in delayed matching to sample and oddity matching with children.

Two kinds of mediating behavior were compared with respect to their effectiveness in variable-delay matching-to-sample and oddity-matching tasks. Each of four 5-year-old children was trained to emit either differential or common mediating responses. The differential mediating response consisted of pressing a specific computer key corresponding to either of two possible sample stimuli (a red or a green square). The common mediating response consisted of pressing one of the two response keys regardless of the sample. The differential-response subjects did not show the typical, delay-related decrease in matching-to-sample performance that characterized the behavior of common-response subjects. An oddity-matching task was then introduced, and subjects were instructed to use the mediating keys however they preferred, including not at all. Differential-response subjects continued to respond on the originally trained mediating keys in response to sample presentation and later reversed their choice responding, thus accommodating the oddity-matching requirements. Common-response subjects continued to emit the previously trained mediating response and experienced limited success in oddity matching. Results were interpreted in terms of stimulus control, instructional control, and experimental history.     

Quantification of the effects of chlorpromazine on performance under delayed matching to sample in pigeons.

The effects of four doses of chlorpromazine (dose range 0.5 to 12.5 mg/kg) on performance under a delayed matching-to-sample procedure in pigeons was investigated, using the exponential model of memory (White, 1985). Performance was measured using a bias-free measure of discriminability, log d (Davison & Tustin, 1978), and negative exponential functions were fitted to individual-subject and group data at each dose level. A decrease in matching accuracy was found to be caused by an increase in the rate of forgetting, b, and a decrease in the initial discriminability, log d0. Changes in rate of forgetting and discriminability occurred at doses that had no statistically significant effect on response latency. The exponential model of memory accounted well for the data and provided a useful way of quantifying the effects of chlorpromazine on the processes involved in delayed matching-to-sample performance.
