- This study investigated the effect of reversal of response scales in a questionnaire. Two versions, A and B, were constructed. A was identical with B except that all response scales were reversed in B. The two versions were randomly distributed to a group of psychology students. No statistically significant differences were found concerning means and standard deviations of the response distributions when the sign test was applied to six different groups of response scales in the questionnaire. A tendency to select response categories to the left could be seen in the data. This tendency has later been confirmed by other researchers.

Marked reversals in a questionnaire

- In an attitude investigation with 260 respondents and 75 Likert type attitude statements a number of reversals of answers were found in the questionnaires, i.e. first marking response 2 and then changing it to 4. There were 71 reversals for items 1-25, 54 reversals for items 26-50 and 16 reversals for items 51-75, which suggests a practice effect. The mean number of words in the three groups increased (7,6 to 8,7 to 10,4). 7 items had 5 or more reversals - they hade the mean 5,9 words but some of them had words with negative prefixes. The method of counting and analyzing reversals in questionnaires is relevant for judging reliability. Some wrong answers may never have been reversed.

O - factor analysis of mood ratings
- 1981

In: Applied psychological measurement. - : SAGE Publications. - 0146-6216 .- 1552-3497. ; 5:4, s. 459-465

Journal article (peer-reviewed)abstract
- In O-factor analysis an analysis is made on data from many variables with only one individual who is measured on several occasions. The occasions are then correlated across the variables. This paper demonstrates the usefulness of O-factor analysis in studying how feelings are structured and how situational factors influence feelings. Fours subjects made self-ratings on several occasions using variables they had chosen themselves. Data were O-factor analyzed, and factors were interpreted in terms of feelings common for situations which loaded on the factors. Problems and applicability of the method in psychotherapy research are discussed.
