The purpose of the study have been: (1) to provide an explanatory, descriptive, and analytic viewpoint of the functions and structure of crisis intervention centers (2) to provide an intensive investigation of counseling and treatment practices in crisis intervention centers and (3) to relate the experiences that the writer has encountered as a resident counselor at Help House Inc. (twenty-four hour drug and crisis intervention center in Denton, Texas) to sociological, psychological, social psychological and philosophical constructs that deal with or pertain to crisis intervention, particularly in the area of drug use. The study indicates how participatory observation serves as an aid in acquiring insight into sociological areas such as crisis intervention centers. The role of the participatory observer is most important because concepts and theories arise out of actual situations.

This investigation concerns the problem of current health care utilization by aged blacks. Utilizing Andersen's model, the volume and pattern of physician utilization associated with selected predisposing, enabling, and need variables is described for an aged population of 163 interviewed blacks residing in Census Tract 212, Denton, Texas, in 1972. None of the six socio-demographic, economic, or health status variables analyzed, through use of Somers' dyx, allowed substantial reduction .of error in predicting a physician visit in the past year. Representing need, selfrated health status was the best predictor variable. Its proportional reduction in error increased from 17 percent to 30 percent, for those with five to seven years education, and to 23 percent, for those reporting the least income.
