Psichometric equivalence of an improved Basic Languaje Morningness (BALM) Scale using industrial population within comparisons / Frederick M. Brown

Sumario: An existing 13-item composite circadian rhythm "morningness" scale was simplified into a "Basic Language Morningness" (BALM) scale at a seventh grade (12-13 years) reading level.
