Sex and cultural differences in the factorial structure of the self-directed search

Holland's Self-Directed Search was administered to 247 male and 252 female high school students, aged 16 to 18 years, attending state schools in New Zealand. Principal factor analysis was used in an attempt to identify six orthogonal factors analogous to Holland's six personality types. The Social and Enterprising scales could not be split into two factors in either sample, and the Investigative and Realistic scales defined a single factor for the female students. Computed distances between pairs of the six personality types in five dimensional factorial space were compared with the relative ordering of the distances expected from Holland's hexagonal model. The positions of the types in space corresponded more closely with the model for the males than they did for the females. The results, in conjunction with those of similar studies in Israel and the United States, imply that the correspondence between some summary codes on the SDS and existing occupational classifications based on Holland's types may be less than perfect, particularly for females. Also, care should be taken when using codes on the SDS to calculate Holland's indices of “consistency,” especially for females.     

An alaryngeal stutterer: A case history

This case study describes an individual who as a stutterer underwent a total laryngectomy and right hemithyroidectomy. Following the Doehler method of esophageal voice training, the client continued to exhibit dysfluent speech behaviors. The Iowa “Stutterer's Self-Rating of Reactions to Speech Situations” and the “Checklist of Stuttering Behaviors” were used to ascertain whether the stuttering behaviors had changed and to what degree.
