The Gottschalk-Gleser-Scales |
The Gottschalk-Gleser content analysis was developed by Louis A. Gottschalk & Goldine C. Gleser in 1969. It is a content analysis technique for the measurement of affects. "Affects are feeling states that have attributes of quality and quantity. Affects and emotions have subjective, purely psychological components as well as physiological, biochemical, and behavioral concomitants." (Gottschalk & Gleser, 1969, p. 14) |

Gottschalk & Gleser described a lot of different content analysis scales:
To measure anxiety (or the other scales) you need texts. Texts can be produced by 5-minute verbal samples with the following standard instruction: "This is a study of speaking and conversation habit. I would like to talk to you for five minutes about any personal interesting or dramatic life experience you have ever had. If you finish telling about one life event, you can continue on telling about another one until the five minutes is over. While you are talking I would prefer not to reply to any questions you have until the five minutes is over. If you have any questions, I will be happy to respond to them now." (Gottschalk & Bechtel, 1993, p. 15)
The text must be transcripted and analyzed according to very strict rules, described in Gottschalk, Winget & Gleser (1969) or in Schöfer (1980, in German). The result are row scores which must be calculated to scores by the following formulas (formula 1 for the six sub scales, formula 2 for the total anxiety score)
Formula 2 (ZS=total score, WZ=number of words, R1 to Rn=row score of the subscales)
The Gottschalk-Gleser-Scales were used in many fields like in psychosocial research or biomedical research (for an overview see Gottschalk, 1995). The validity and reliability of the scales were checked often, they are very satisfying. For English samples norms are available. The Gottschalk-Gleser analysis is done manually very expensively and needs a very experienced rater, that's why Gottschalk and colleagues developed
a computer program for the analysis of English speech samples (Gottschalk 1985, 1994, 1995, 1997; Gottschalk & Bechtel 1982, 1989, 1993, 1995; Gottschalk, Hausmann & Brown, 1975; Gottschalk, Stein & Shapiro, 1997). But for German speech samples, in spite of the wide use by German researchers, a computer version of the scales was not available.
