Lifshitz has documented that conceptualization of old age is influenced by stereotypes. Milligan, Powell, Harley and Furchtgott, made evident that elderly people with poor health have a tendency to see themselves as the stereotype of an "old person", whereas those with better health tend to see themselves as younger people. Lasher and Faulkender have stressed the importance of anxiety in the process of getting old as an important factor adjusting to themselves. Lack of adjustment may manifest in four main dimensions: physical, psychological and social, and transpersonal or spiritual. These four dimensions are synthesized in three specific fears: 1. Fear of the process of aging, 2. fear of the state of being old, and 3. fear or anxiety facing old people. Based on this theoretical frame, the authors developed the Anxiety about Aging Scale, and Watkins, Coates and Ferroni pointed out the need to adapt it in order to apply it on elderly people. The objective of this paper is to evaluate the psychometric properties of the original Lasher and Faulkender scale, as well as presenting an adapted version for Mexican elderly people. 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: EAEO: 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.… [ABSTRACT FROM AUTHOR]
