A psychoeducational program for families of affectively ill children and adolescents.

OBJECTIVE: The objective of this study was to evaluate the acceptability, feasibility, and efficacy of a family psychoeducational program for the parents of affectively ill adolescents. METHODS: Sixty-two parents of 34 affectively ill adolescents received one 2-hour psychoeducational session that covered information about the diagnosis, course, and treatment of affective illness. Methods of coping with an affectively ill family member also were discussed. The view of depression as a chronic and recurrent illness was strongly emphasized. RESULTS: Participants showed improvement in knowledge about depression and in modification of dysfunctional beliefs about depression and its treatment. Almost all participants found the program both useful and interesting. CONCLUSIONS: These findings support the feasibility, acceptability, and to a modest degree, the efficacy of a family psychoeducational program for parents of affectively ill adolescents. Additional studies should address the impact of such programs on compliance with treatment, clinical outcome, and family life.

Timed ammonia release for steers.

Slow and rapid ruminal ammonia release rates were simulated by intermittent urea feeding with steers fed winter range grass. Four 360-kg, ruminally-cannulated steers were fed 208 g prairie hay (2.56% crude protein) hourly with the following daily dietary supplements: (1) Urea provided continuously (C) at a rate of 3.5 g/hr for 24 hr; (2) urea provided moderately (M) at a rate of 14.2 g/hr for 6 hr (3) urea offered rapidly (R) as 85 g in 1 hr, or (4) no supplemental urea (O). Ruminal ammonia remained stable with treatments C and O at 12.8 and 1.6 mg/dl, respectively. Treatments R and M peaked 1.5 and 6.5 hr after the start of urea feeding at 41.8 and 37.1 mg/dl, respectively. Nonammonia nitrogen concentrations in the rumen were increased by an average of 23% with urea supplementation. Dry matter digestibility was increased by 5% with addition of urea, regardless of the rate of urea administration. Daily nitrogen retentions were 12.4, 12.2, 11.4 and -7.1 g (P < .01) for C, M, R and O, respectively. Simulated slow ammonia release rates enhanced neither dry matter digestibility nor nitrogen retention. Metabolic use of ammonia in the rumen of steers fed forage was not improved by an attenuated release rate.
