Multifactorial assessment of bulimia nervosa.

We investigated a multifactorial approach to the assessment of bulimia nervosa by means of hierarchical factor analysis. Two hundred forty-five bulimia nervosa patients and 68 patients with either anorexia nervosa or eating disorders not otherwise specified were administered a self-report battery that was organized into 21 dimensions relevant to eating disorder patients. When dimensions from this battery were subjected to hierarchical factor analysis, support for bulimia nervosa as a unique diagnostic category was obtained. However, the emergence of 3 secondary factors and 6 primary factors suggests that bulimia nervosa can also be described more complexly. The emergence of a multifactorial model of bulimia nervosa that incorporates several existing undimensional models suggests the potential for both divergent and complicated clinical presentation in bulimia nervosa patients.

The Revised Asthma Problem Behavior Checklist.

The Asthma Problem Behavior Checklist (APBC) has proved to be an accurate and invaluable instrument for pinpointing potential behavioral problems in children with the disorder. This article presents the Revised Asthma Problem Behavior Checklist (RAPBC). The value of the RAPBC is that: (a) it has proven reliability when tested with asthmatic adults; (b) the change from a dichotomous yes/no format, used in the APBC, to a 5-point Likert-type answer format adds greater sensitivity to the instrument; and (c) data gathered with the RAPBC compare favorably to information gathered in two previous studies with the APBC. Considering the reliability and validity of the RAPBC, it should prove useful in both clinical and research settings.

A method for studying controlled substance use: a preliminary investigation.

This study examined relapse following treatment in a smoking reduction program. Twenty-two smokers with an average daily smoking rate of 25.7 cigarettes were provided a reduction-oriented smoking self-management program. Subjects were then classified on the basis of their reduction at posttreatment. A 50% or greater reduction from pretreatment qualified subjects as successful reducers. To provide further understanding of controlled smoking, subjects who successfully maintained at least a 50% reduction (at three month follow-up) were compared to those subjects who were unable to maintain that level of reduced smoking. A set of cognitive, smoking history, and reduction motivation variables were used to compare the two groups in a stepwise discriminant function analysis. Two variables, internal locus of control and self-label as a nonsmoker, produced an overall correct classification rate of 88.9%. Multiple regression analyses further demonstrated the importance of these two cognitive variables; self-label and internal locus of control accounted for 50.4% of the variance in smoking at three months follow-up. The implications of these findings for future study of controlled smoking are discussed.

The "Asthma Self-Efficacy Scale".

According to Bandura, a person's expectations that a favorable outcome will follow a particular behavior are not sufficient to promote the occurrence of the behavior; the person must also believe that he or she will be effective at performing the behavior. The latter is referred to as self-efficacy. It has become a major focus in assessing patient performance of skills required to manage their illness. The present paper describes the development, testing, and applicability of an instrument for assessing self-efficacy in asthmatic patients. It notes that the Asthma Self-Efficacy Scale is not only a reliable paper-and-pencil instrument, but that it has a wide potential applicability throughout health care settings in measuring self-efficacy in asthmatic patients. The Asthma Self-Efficacy Scale is included.
