Bh. Munro et al., REEXAMINATION OF THE PSYCHOMETRIC CHARACTERISTICS OF THE LAMONICA-OBERST PATIENT SATISFACTION SCALE, Research in nursing & health, 17(2), 1994, pp. 119-125
The purpose of this study was to provide further psychometric testing
of the 41-item La Monica-Oberst Patient Satisfaction Scale (LOPSS). Da
ta were drawn from three studies designed to study a model of nurse sp
ecialist transitional care (n=307). Previously, the scale had been tes
ted with oncology patients. This study included three groups of nononc
ologic female patients. Potential scores on the LOPSS range from 41 to
205; actual scores ranged from 93 to 205, with a mean of 175 (SD = 24
), indicating a positively skewed distribution. Coefficient alpha for
the entire scale was .98. An examination of the individual items indic
ated that the LOPSS might be shortened without subsequent loss of info
rmation. Thirteen items with low item-total correlations or low variab
ility were dropped. The resulting 28-item scale had a mean of 118.7 an
d a SD of 17.3. Coefficient alpha was .97. The results of a factor ana
lysis of the revised scale were similar to those reported by La Monica
, Oberst, Madea, and Wolf (1986). The results indicate that the scale
is useful for nononcologic patients. The difficulty remains the positi
vely skewed distribution of scores. More sensitive items need to be de
veloped. (C) 1994 John Wiley & Sons, Inc.
