Lund, Thorleif – Scandinavian Journal of Educational Research, 2012
One purpose of the present paper is to elaborate 4 general advantages of the mixed methods approach. Another purpose is to propose a 5-phase evaluation design, and to demonstrate its usefulness for mixed methods research. The account is limited to research on groups in need of treatment, i.e., vulnerable groups, and the advantages of mixed methods…

Lund, Thorleif – Scandinavian Journal of Educational Research, 2010
The purpose of the present paper is to critically examine causal inferences and internal validity as defined by Campbell and co-workers. Several arguments are given against their counterfactual effect definition, and this effect definition should be considered inadequate for causal research in general. Moreover, their defined independence between…

Haugen, Richard; Lund, Thorleif; Ommundsen, Yngvar – Scandinavian Journal of Educational Research, 2008
The purpose of the study was to explore the relationship between attribution and selected personality dispositions, as well as self-serving attribution. Four hypotheses were formulated: (1) Attributions for positive events correlate differently with the five personality dispositions than attributions for negative events, (2) factor analysis and…

Ommundsen, Yngvar; Haugen, Richard; Lund, Thorleif – Scandinavian Journal of Educational Research, 2005
The purpose of the present study is to explore how academic self-concept and implicit theories of ability are related to four self-regulation strategies--motivation/diligence, concentration, information processing, and self-handicapping. The hypothesis is that academic self-concept and an incremental theory of ability are (1) positively related to…

Lund, Thorleif – Scandinavian Journal of Educational Research, 2005
The purpose of this article is to critically examine some stated discrepancies between qualitative and quantitative research by taking actual studies as a starting point. It is argued that in ordinary empirical research within psychology and education, both approaches should be considered based on critical realism, and that the ordinary validity…

Lund, Thorleif – Scandinavian Journal of Educational Research, 2005
The purpose of the present paper is to emphasise the importance of inferences in an empirical study and to demonstrate how the inferences depend on a wider context. For that purpose a metamodel of central inferences is proposed, where each inference is characterised according to three dimensions: relevance, legitimacy, and validity. The relevance…

Haugen, Richard; Lund, Thorleif – Scandinavian Journal of Educational Research, 2000
Studied how achievement motives and incentive values were related to attribution for 166 advanced education majors in Norway. As expected, success-oriented persons attributed positive events more internally, stably, and globally, and negative events more externally, unstably, and specifically, than did failure-avoidant persons.

Accounts for the paradox posed by F. Lord (1967) concerning the logic behind statistical adjustment with preexisting groups in both causal and descriptive terms. The account of the paradox illustrates the need for causal metamodels. (Author/SLD)

Lund, Thorleif – Scandinavian Journal of Educational Research, 1995
Four general criteria are proposed for the choice of a metrical solution for a causal effect: (1) compatibility with the effect; (2) ease of communication; (3) lack of measurement error bias; and (4) stability across subjects and situations. These criteria are illustrated for randomized and nonrandomized designs. (SLD)

Lund, Thorleif – Scandinavian Journal of Educational Research, 1993
Based on the division of attained change for each treated individual into causal and noncausal change, the product-moment correlation between causal change and initial level is studied and compared with the correlation between attained change and initial level. Relevant formulas for true scores at population level are presented. (SLD)
