Nr. Kressin et al., Personality traits and oral self-care behaviors: Longitudinal findings from the normative aging study, PSYCHOL HEA, 14(1), 1999, pp. 71-85
We examined the persistence of oral self-care behaviors (toothbrushing and
'other oral self-care behaviors' (using dental floss, gum stimulators, mout
hwash, or a water irrigation device)) over time and whether personality tra
its are associated with the performance of such behaviors. Using data from
the VA Normative Aging Study/Dental Longitudinal Study, we examined whether
the personality traits of anxiety/neuroticism or extraversion from two dif
ferent personality measures (the 16PF and EPI-Q) were related to the perfor
mance of two types of oral self-care behaviors over thirteen years. Oral se
lf-care behaviors were relatively stable and consistent over time, and a su
mmary measure was developed to reflect their average frequency. Regression
analyses showed that both measures of neuroticism/anxiety were negatively a
ssociated with toothbrushing, while both measures of extraversion were posi
tively associated with the performance of other oral self-care behaviors. R
esults are similar to other findings demonstrating a link between personali
ty traits and health behaviors; these results are also discussed in terms o
f their import for future oral health promotion activities.
