Personality factors associated with anticipatory nausea/vomiting in patients receiving cancer chemotherapy.

One hundred cancer chemotherapy patients rated the severity of pre- and posttreatment nausea and emesis and completed the State-Trait Anxiety Inventory. In addition, scores on the Millon Behavioral Health Inventory were obtained for 59 of those patients. Thirty-three percent of the patients reported having experienced anticipatory nausea and 11% reported having experienced anticipatory vomiting. Patients who experienced anticipatory nausea had more posttreatment nausea and vomiting, were more depressed, and were characteristically more anxious than other patients. A personality profile including the future despair, social alienation, and inhibited style (from the Millon Behavioral Health Inventory) identified patients with anticipatory nausea.

Learned aversions to chemotherapy treatment.

Recent advances in behavioral psychology and its application in medical settings have yielded effective methods for reducing distress in patients undergoing cancer treatment. This article focuses on the control of anticipatory nausea and vomiting in patients receiving chemotherapy. Four behavioral methods (i.e., hypnosis used with guided imagery, progressive muscle relaxation training with imagery, biofeedback with imagery, and systematic desensitization) are evaluated. Clinical issues and the relevance of behavioral medicine to health education are addressed.

Treatment of excessive crying in a terminal cancer patient: a time-series analysis.

Spectral analysis was used to investigate the modification of the excessive crying (48% of waking time observed during baseline) of a terminal cancer patient. Initial assessment revealed a cyclic pattern of crying and dozing throughout the day and night. Intervention involved timeout from social stimulation contingent upon crying and differential social reinforcement for behaviors incompatible with crying. Analysis showed the gradual elimination of crying during the 15-day intervention. During the initial phase of intervention crying ceased to be emitted in the presence of hospital staff but was evoked by the presence of family members. As this pattern of crying diminished, the frequency and duration of family visits, as well as the frequency of positive patient utterances and conversation, increased. Clinical, ethical, and methodological issues surrounding the use of timeout are discussed.

Behavioural analysis and control of psychosomatic symptoms of patients receiving intensive cancer treatment.

During the course of cancer treatment behavioural symptoms such as gagging, coughing and vomiting often develop in the absence of apparent tissue damage. Moreover, symptoms whose onsets are clearly related to disease processes often continue after the disease has been eliminated. The reported research incorporated time-series analyses of patients' behavioural symptoms and assessments of behavioural interventions involving the modification of nurse--patient and family--patient interactions. Results showed that: (1) inadvertent social reinforcement by hospital staff and family members fosters the development of behavioural symptoms; (2) personnel associated with treatment can become discriminative stimuli for social attention and thereby evoke symptom behaviours; and (3) by modifying the social reinforcement contingencies associated with treatment protocols, the frequency of psychosomatic symptoms can be reduced without changing the quality of medical/nursing care and social interaction.

Timeout as a reinforcer for errors in a serial position task.

After learning to press keys in a predetermined serial position sequence, with timeouts scheduled as a consequence of errors, monkeys developed stereotyped errors. As soon as a new trial started, the animals would make an error. On trial after trial, they pressed the same incorrect key at the first member of the sequence, even though they had previously learned the sequence. First-member errors occurred even when sequences of fully bright keys marking correct choices were presented. When timeout was eliminated as a consequence of one first-member error, subjects switched to an error that did produce the timeout. When all first-member errors failed to produce timeout the monkeys ceased responding. Both prefeeding and reduction in reinforcement density resulted in stereotyped errors occurring earlier in the session.
