Method.

Two independent samples of elder adults were used (n=234 and n=151) selected by availability within a government health clinic; on average, they were 63 years old. The original Lasher and Faulkender scale was translated into Spanish following a double blind procedure, using Likert type answer options with four alternatives. Two questionnaires were used, which included the original scale (EAE-O), in one, and the adapted scale (EAE-A) in the other, as well as the sub-scale of attitude facing one's own aging of the Philadelphia Geriatric Center Morale Scale, APE (2), and the Suicidal Ideational Scale (EIS), designed by Roberts (3). Additionally, interviewees were asked: «If you should have to set an age, forgetting a little about what doctors and people say, at what age would you consider that you really start to be "Old"? » and at what age do you think one would get "very old"? The scales were applied to subjects who agreed voluntarily to participate in an anonymous and informed way. Resulting data were analyzed with the system SPSS, v. 11.0.

Factorial structure. A factorial analysis with varimax rotation and eigen values greater than 1 produced the following results: EAE-O: The structure obtained was compounded by three factors that explained 53.1% of the variance with Cronbach's alpha of .74 (Fear facing one's own aging, Positive attitude towards old people and Optimism facing one's own aging). EAE-A: The analysis shed a factorial structure compounded by four factors that explained 60.8% of the variance with a general internal alpha consistency of .76 (Positive attitude towards old people, Fear of physical changes, Age and satisfaction with the self and life, and Age and dissatisfaction with the self and life).

Concurrent validity. EAE-O. The correlation among the total punctuations of the EAE-O and APE was moderate and significant (r=.481, p<.000). The factors Fear facing one's own aging and Optimism facing one's own aging of the EAE-O, calculated here, obtained a moderate association with the total punctuation of the APE (r=.423, p<.000; r=.333, p<.000, respectively), and the factor of Positive attitude facing old people reported a very low association and no significant (r=.075, p=.252). As expected, the two factors of the APE that seem to evaluate positive and negative attitudes facing aging obtained moderate associations and significant with the two scales of the EAE-O that seem to evaluate the same attitudes (Optimism facing one's own aging, r=.415, p<.000; and Fear facing one's own aging, r=.424, p<.000, respectively). Consequently, a very low association was obtained when relating it with the opposite factor (v.gr. negative vs. positive).

EAE-A. Associations between the factors Age and dissatisfaction and Age and satisfaction (similar to the factors of Fear facing one's own aging and Optimism facing one's own aging) and the total score of the APE were moderately high (r =.499, p<.000, and r =.383, p<.000, respectively), as long as the other two factors of the EAE-A presented associations moderately low. As it was to be expected, again were associated in an important way the EAE-A scales with a positive nuance (aging and satisfaction, Positive attitude before old people) with the scale of the APE's Positive attitude, and vice versa. The factors of aging and dissatisfaction and Fear to physical changes were significantly associated with the negative attitude of the APE.

The relationship between perceived aging (when is one old?, and when is one too old?) and anxiety before aging; with a marginal meaning, it was found that those people with low levels of anxiety tend to refer an age but remote (X- =68.2 years, DE= 9.8), than those with high levels of anxiety (X- =64.47, DE=11.7; t=1.74, gl=57.9, p=.08), to the question of the age that one is "old". Concerning the question when is one too old?, the same tendency it was observed, but this time in a meaningful way (Low Anxiety: X- =80.9 years; DE=9.1; High Anxiety: X- =76.4 years; DE=9.1; t=2.51, gl=128, p=.01). Regarding suicidal ideation, it was found that subjects who score low levels of anxiety before aging according to EAE-A also had lower levels of anxiety of suicidal ideation (X- = 1.25, DE=1.47), than those with high levels of anxiety (X- =2.35, DE=2.51; t=2.84, gl=64.45, p=.006).

Results contributed by the psicometric analysis of both versions of the EAE have allowed to confirm their utility in Mexican samples. Together, the EAE-O seems to investigate the anxiety before aging as a stage of life; as a state of being, and perhaps could be specially useful on people who are not necessarily elders (old people caretakers, adults between 50 and 60 years old in a frank transition towards the socially conceived old Adulthood, etc.). However, it could be worthwhile to focus on the singular situation of a subject regarding his own aging process (physical or psychosocial), when this is precisely the objective to be investigated; the EAE-A could be useful to this effect.

Elderly adults seem to conceptualize "being old" as an event that occurs approximately at 70, and "very old" around 80; this chronological approach seems to obey, at least in part, to the level of anxiety before the aging process; the higher the anxiety, the earlier the beginning of old age. Results allowed to highlight the anxiety facing aging like a variable importantly linked to the psychological imbalance in the old adult, as it was possible to evidence in broadly significant terms with the EAE-A as with the APE, starting from their relationship with the suicidal ideational, and more, when this relationship is found in fellows without current marital commitment and of low educational level. This should be considered in programs of attention to this age sector where these factors of risk are evaluated with a view toward preventing the incidence of suicides. Different studies have highlighted the importance of developing a positive attitude before one's own aging and that of the other ones, in order to achieve a successful aging. This suggests the need to identify methods to promote positive attitudes in young adults toward the elders and the aging process.
