Risks associated with environmental enrichment: intestinal obstruction caused by foraging substrate.

Questions are occasionally asked about the safety of enrichment techniques, considering that many novel ways are frequently employed to ensure environmental complexity. A juvenile male vervet monkey was found with a phytobezoar of straw obstructing the sigmoid colon. The straw was foraging substrate, which is used in communal cages. Due to the extent of the resulting necrosis in the sigmoid and descending colon, the monkey had to be killed. This is the only individual to have suffered a harmful effect from the foraging substrate from amongst 120 vervet monkeys, which have been permanently housed on straw for over 5 years.

Self-esteem, ethnic identity, and behavioral adjustment among Anglo and Chicano adolescents in West Texas.

This study provides a comparison of similarities and differences with respect to ethnic identity between Anglo and Chicano adolescents from Texas. A path analysis model was used to test a theoretical assumption concerning proposed antecedents and consequences of self-esteem. Research instruments included the Rosenberg Self Esteem Scale, the Semantic Differential (scales for Myself and My Ethnic Group) and the McGuire White Measure of Social Status. Results were consistent with the interpretation that there is a relationship between being Chicano and having lower self-esteem, lower behavioral adjustment, and higher ethnic esteem. The prediction that ethnic esteem would mediate between ethnic group and self-esteem was upheld. Variables such as ethnic group membership per se and sex appear as or more important to the prediction of behavioral level. Clinical implications include recognizing that Chicanos low in self-esteem or behavioral adjustment should not automatically be considered unusual. The problems faced by this group are considered as having something in common with other groups of people who have more problems, lesser status, fewer resources, and fewer sources of available help.

Integration of a behavior modification program into a traditionally oriented residential treatment center for children.

The historical background and early contributions of the Emma Pendleton Bradley Hospital, the first psychiatric hospital for children in the United States, are described. The focus of this report is on the incorporation of the treatment modality of behavior modification into this traditional psychoanalytically oriented program. Beginning with exploratory studies in the mid-1960s, in recent years within the residential center there has been a separate Autistic Unit, in which the major treatment strategy is consistent application of behavior modification principles and programs. Changes that have occurred in the course of developing the behavior modification program are discussed to show some of the positive and negative aspects of introducing such a radical change into a traditional setting. Case studies are included to reveal both the failures and the successes that have been encountered in treating psychotic children with either psychotherapy or behavior therapy. Description of the current status of the program shows that treatment is comprehensive, including psychodynamic and behavioral approaches, medication when warranted, and special education. The role of parents in the program is now very different from that ascribed to them in traditional psychoanalytically guided treatment.

Residential treatment of disturbed children and adequacy of their subsequent adjustment: a follow-up study.

To study residential treatment outcome, a follow-up questionnaire sent to families of former child patients was used to assign them to categories of "good", "fair," or "poor" overall adjustment. The three groups were compared on variables such as presenting symptoms, duration of psychotherapy, amount of drug therapy, and prognosis on discharge; several therapist variables were also studied. Findings, some unexpected, are discussed.

Childhood psychosis. The problem of differential diagnosis.

In a study of 66 former child psychiatric patients, Form E-1 of Rimland's Diagnostic Check List (DCL) was found to be an effective instrument for differentiating autistic, other psychotic, and nonpsychotic disturbed children. Follow-up study revealed more favorable outcomes in nonpsychotic cases, with significant association between DCL scores and improvement following discharge. Scores indicative of autism on the DCL were also significantly associated with being of the Jewish faith.
