This study examined the impact of a brief psychological intervention on a number of criteria, these being psychological variables, the use of medical services, and the nature of medical problems. Twenty-five soldiers treated in the Clinic were compared to 28 non-treated soldiers, randomly chosen from the general population on the .base. Psychological factors were measured on Global Assessment Scale: I-E Scale (4), A-State and A-Trait Anxiery Scale (5), and the Sensitivity of Symptom- and Nonsymptom-focused Criteria (2). Use of medical care was the number of outpatient visits made by the soldiers. Nature of medical complaints involved dividing medical problems into three categories: medical complaints with possible psychological components, clear psychological complaints, and clear medical complaints. The psychological treatment was a brief active technique focusing and defining immediate problems and working out practical ways of dealing with them. Essential results indicated that (1) at intake, the treated group showed greater emotional instability than the controls as reflected by the significantly higher scores on state and trait anxiety, general neurotic feelings, somatization, cognitive performance difficulties, depression and fear, and anxiety. (2) In the treated group over 4 mo., significant decreases on the above psychological measures were found. Except for state anxiety, the treated group after 4 mo. was similar to controls on all psychological measures. (3) Comparison of pre- and the 3-mo. poscrreaunent periods showed significant reductlon in psychological visits by the treated group, but controls showed no such change. Clearly the brief psychological intervention was effective. In general, the effect of psychological intervention appeared clearly positive. It improved the emotional state of the treated sample which confirms previous findings ( 1). It also led to adequate use of medical services which, particularly in the military context, has many broad ramifications. We maintain that the Primary Care Air Force physician (as well as, in some cases, the soldiers' officers-in-charge) may be able to deal with many of the psychological problems, provided that they are given adequate consultation and supervision by the Mental Health Officer (3) to enable them to detect the problems early in their develop ment. Effective cooperation and coordination among the Mental Health Officer, the military physician, and officer-in-charge is crucial for soldiers' improved mental health and effective use of medical services.
