Perceiving oneself as 'disabled' or as having a 'disabling condition': a discriminant function analysis.

Using discriminant function analysis, information obtained in telephone interviews with a national, random sample of 1000 Americans with self-ascribed disabling conditions was analysed to cast light on differences between individuals who did and did not consider themselves 'disabled'. Maximum separation between the two groups was attained by an equation of six descriptors. In the order of their importance they were (1) the belief that others who knew them well considered them disabled, (2) self-rated severity of disability, (3) identification with others with disabilities, (4) gender, (5) perceived extent of limitations, and (6) needing equipment to walk. Somewhat different equations were generated for sampled men and women. An appreciation of these results in terms of a person's fit with his or her environment is offered.

Investigations on the relation of dysgnathias and S-sound pronunciation.

A registration-form phonetic test has been developed which incorporates an established method for checking fine motor skills. Using an objective measuring and computing technique (electro-acoustic sound analysis according to the sound-seeking method), the author studied the pronunciation of the S-sound of one group of eugnathic and three groups of dysgnathic test persons. There were significant differences in sound characteristics between the normal group and all groups with dysgnathia (P = 0.001). Therefore it is considered that not every patient with an anomaly of the tooth position must have a disturbance of the S-sound. In contrast to the relatively narrow variations in the normal group, in all groups with dysgnathia considerable dispersions were registered. The anterior open bite occupies first place with regard to its susceptibility to disturbances of the S-sound. The statistical analysis of the partial energy values of all the S-sound spectra revealed typical normal behaviour on the one hand, and characteristic differences between the groups with dysgnathia and the group with eugnathia on the other. The information which is most important for the valuation of the S-sound are contained in the frequency area up to 9 kHz.
