Ea. Oconnor et al., GENDER AND SMOKING CESSATION - A FACTOR STRUCTURE COMPARISON OF PROCESSES OF CHANGE, Journal of consulting and clinical psychology, 64(1), 1996, pp. 130-138
This study examined gender differences in the pattern of process use f
or smoking cessation using the Processes of Change Questionnaire (J. O
. Prochaska, W. F. Velicer, C. C. DiCiemente, & J. Fava, 1988). The go
als were (a) to determine the degree to which the covariance structure
of the Processes of Change Questionnaire is invariant across gender,
(b) to test the existence of the theoretical 2-factor process model us
ing confirmatory factor analysis, and (c) to explore mean differences,
if found, in the use of the 10 processes of change across 4 stages of
change (precontemplation, contemplation, preparation, and action). Th
e sample (N = 516) had an equal distribution of men and women across t
he stages of change. Results demonstrated that the structure of the me
asure for men and women was invariant at the level of the variance-cov
ariance matrices and that the hypothesized 2-factor model fit the data
. Only stage of change predicted the experiential and behavioral proce
ss factors.
