- The metric properties of five different response scales in measurment of attitudes, interests and personality traits are studied with an experiment group (N = 97) and a control group (N=40). The scales were different in how equal the distances between the response alternatives were.

Attitudinal types concerning environmental problems

Ingår i: Man-Environment-Systems. - 0025-1550. ; 5:3, s. 183-184

Tidskriftsartikel (refereegranskat)abstract
- In an investigation with linear typal analysis on a representative sample of the Swedish population (N = 229 participants) and a local sample with N=31 environmental activists two attitudinal types were found. Type I respondents seemed to be more concerned than type II respondents. Type I gave environmental problems a higher priority, was critical against authorities, industry, city growth, and motorism, more restrictive against economic growth, more worried about the future, and demanded more information and public influence than type II. By computing Euclidean distances to the mean 64-variable profile of the two types 28 of the activists were classified as type I. The typology was crosstabulated against 46 other variables. There were no correlations with conventional background variables.

- 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.

Having a strategy for new service development - does it really matter?
- 2013

- Purpose - The aim of this study is to investigate the role of key strategic factors in new service development (NSD). In particular, the role of service development strategy, a formalised development process, integrated development teams and customer co-creation were investigated and the results were compared with managers beliefs. less thanbrgreater than less thanbrgreater thanDesign/methodology/approach - The study used a sample of more than 500 service development projects to test a NSD conceptual model. Regression analysis was used to test the relative importance of the key strategic factors, and the results were compared with managers beliefs. less thanbrgreater than less thanbrgreater thanFindings - The results show that managers believe that customer co-creation is most important in order to succeed with NSD. However, contrary to management belief, a service development strategy is the "missing link" in improving NSD performance. In addition, the research highlighted an interaction effect between integrated development teams and customer co-creation, which means that project managers should focus on individual competencies on the development team and how they interact with customers throughout the NSD process. less thanbrgreater than less thanbrgreater thanOriginality/value - For a long time, NSD has failed to receive the attention it deserves, not just in practice but also in service research. This study shows that the number of new services put on the market and then withdrawn because of low sales remains as high as 43 per cent. This paper contributes knowledge on how to reduce the number of failures in NSD by pointing out the key strategic factors that influence NSD performance.

Marked reversals in a questionnaire
- 1980
-
Ingår i: Perceptual and Motor Skills. - : SAGE Publications. - 0031-5125 .- 1558-688X. ; 50, s. 958-958
-
Tidskriftsartikel (refereegranskat)abstract
- 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.

Measures of attitudinal polarization
- 1975
-
Ingår i: Scandinavian Journal of Psychology. - Oxford : Blackwell. - 0036-5564 .- 1467-9450. ; 16:1, s. 247-254

Tidskriftsartikel (refereegranskat)abstract
- Criteria for measures of attitudinal polarization, i.e. degree of opposition among people on a specific issue, are proposed and some formulas, including the standard deviation, are evaluated in relation to the criteria. The formulas were also tested on empirical data with respect to level, dispersion and agreement of received values. The measures on the whole showed a high degree of agreement. There clearly exist instances where the standard deviation is not an adequate measure of attitudinal polarization. Some guidelines are given for the choice of constant values in one of the proposed formulas.

O - factor analysis of mood ratings
- 1981

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

Tidskriftsartikel (refereegranskat)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.

Resource test-driving for service innovation : How ordinary employees innovate new value propositions
- 2012
-
Ingår i: Proceedings of the 15th QMOD-ICQSS conference. - Poznan, Poland : COMPRINT, Poznan Univ. of Technology.
-
Konferensbidrag (refereegranskat)abstract
- PurposeThe purpose of this paper is to investigate the role of ordinary employees in service innovation. Departing from the service-dominant (S-D) logic, service innovation is conceptualized as a resource integration process leading to the creation of value propositions.MethodologyThe paper reports on a case study of service development at three different organizations. Twenty ordinary employees were interviewed. Ordinary employees are defined as those lacking a formal innovation obligation, e.g. frontline employees. These normally have knowledge of both the customers’ needs and the firm’s ability to realize these.FindingsThe findings suggest that ordinary employees contribute to service innovation by test-driving resource integrations and potential value propositions. Specifically, the findings suggest that ordinary employees use three different ways of test-driving resources: Cognitive test-driving; Test-driving in practice, and Discursive test-driving. Although the findings suggest that these ways of test-driving resources are intertwined, they also suggest that parts of the innovation process are dominated by one of these.Research limitations/implicationsThis article is based on a case study of three organizations, thus limiting the possibility of statistical generalization.Originality/valueThe study is novel in several respects: (i) it introduces the notion of resource test-driving; (ii) it provides a systematic empirical analysis of how ordinary employees contribute to service innovation through test-driving resource integrations and new value propositions; (iii) it offers an S-D logic informed service innovation model; (iv) it contributes to the S-D logic by detailing how resource integration takes place in practice.

On the use of the G index in O-, P-, R-. S-, and T-analyses
- 1979
-
Ingår i: Educational and Psychological Measurement. - 0013-1644 .- 1552-3888. ; 39:4, s. 707-710
-
Tidskriftsartikel (refereegranskat)abstract
- The possibility of using the G index and its generalizations in the six basic factor analytic designs is discussed. For O- and Q-analyses G should be used if there is no mutual direction of all the variables, as G is invariant over variable reflection. In all the six designs G should also be used if the scale centre is more suitable as a reference point than the mean value.
