The reliability, validity, and factor structure of the standard 21-item and short 13-item forms of the Beck Depression Inventory were investigated. The sample consisted of 163 participants in a methadone maintenance program. The internal consistency reliability was .85 for the standard and .83 for the short form. The correlation between the standard and short forms was found to be .93. Both forms also correlated significantly with the Zung Self-Rating Depression Scale and University of California-Los Angeles Loneliness Scale. The results support the use of the short form as a reliable and valid brief screening measure of depression.

Part 1 of this two‐part series proposed the use of an interdisciplinary model in the development of psycholegal questions that guide child custody evaluations. It was argued that defining the scope and focus of an evaluation at the time that a court order is entered provides a more structured and clearly defined set of questions to be researched and examined within the context of the behavioral science literature. The present article offers a conceptual model to be used in gathering and analyzing data in child custody evaluations. It is argued that the use of forensic methodology provides a more scientific basis for the information provided by the evaluator to the trier of fact, ultimately resulting in a more useful and accurate picture of the family in question.

This article proposes a model for the interdisciplinary colloboration of judges, attorneys, and evaluators prior to the writting of a court order for child custody evaluation in the formulation of specific psycholegal questions that guide the examination. These questions accurately reflect the concerns of the court, the attorneys, and the parties to the dispute while framing the evaluation questions within the behavioral sciences, suitable for evaluation by a mental health professional. Such a model best suits the court by providing information on specific, legally relevant areas of parenting, child development, and/or mental health useful to the trier of fact.

The reliability, validity, and factor structure of the standard 21-item and short 13-item forms of the Beck Depression Inventory were investigated for 42 male and 143 female college students. The internal consistency reliability was .82 for the standard form and .78 for the short form. The correlation between the standard and short form was .94. Both forms also correlated significantly with scores on the Zung Self-rating Depression Scale, the UCLA Loneliness Scale, and the Rosenberg Self-esteem Scale. The results support the use of the short form as a reliable and valid brief screening measure of depression.
