Necessity as a Function of Skewness.

Frontiers in psychology

Sorjonen K, Wikström Alex J, Melin B.
PMID: 29312058
Front Psychol. 2017 Dec 19;8:2192. doi: 10.3389/fpsyg.2017.02192. eCollection 2017.

With necessary condition analysis (NCA), a necessity effect is estimated by calculating the amount of empty space in the upper left corner in a plot with a predictor X and an outcome Y. In the present simulation study, calculated...

Threshold-like associations as a function of disturbance.

PeerJ

Sorjonen K, Ingre M, Melin B.
PMID: 31656700
PeerJ. 2019 Oct 21;7:e7891. doi: 10.7717/peerj.7891. eCollection 2019.

According to the intelligence-creativity threshold hypothesis, there should be a positive association between intelligence and creative potential up to a certain point, the threshold, after which a further increase in intelligence should have no association with creativity. In the...

Feasibility and implementation of Safer Kids - A parenting program to reduce child abuse.

Child abuse & neglect

van Leuven L, Lalouni M, Enebrink P, Sorjonen K, Forster M.
PMID: 34894587
Child Abuse Negl. 2022 Jan;123:105434. doi: 10.1016/j.chiabu.2021.105434. Epub 2021 Dec 08.

BACKGROUND: Child abuse is a world-wide problem causing long-term suffering for children and large costs to society. Parent-training programs have been shown to reduce harsh parenting but more research on parenting programs specifically addressing child abuse is needed.OBJECTIVE: This...

Accounting for Expected Adjusted Effect.

Frontiers in psychology

Sorjonen K, Melin B, Ingre M.
PMID: 33041911
Front Psychol. 2020 Sep 17;11:542082. doi: 10.3389/fpsyg.2020.542082. eCollection 2020.

The point that adjustment for confounders do not always guarantee protection against spurious findings and type 1-errors has been made before. The present simulation study indicates that for traditional regression methods, this risk is accentuated by a large sample...

Predicting the Effect of a Predictor When Controlling for Baseline.

Educational and psychological measurement

Sorjonen K, Melin B, Ingre M.
PMID: 32655179
Educ Psychol Meas. 2019 Aug;79(4):688-698. doi: 10.1177/0013164418822112. Epub 2019 Jan 08.

The present simulation study indicates that a method where the regression effect of a predictor (X) on an outcome at follow-up (Y1) is calculated while adjusting for the outcome at baseline (Y0) can give spurious findings, especially when there...

Diminishing returns as a function of disturbance.

PeerJ

Sorjonen K, Melin B.
PMID: 32685290
PeerJ. 2020 Jul 03;8:e9490. doi: 10.7717/peerj.9490. eCollection 2020.

According to Spearman's law of diminishing returns (SLODR), IQ test scores are more

Diminishing returns as a function of the association between within-individual average performance and variance.

Heliyon

Sorjonen K, Madison G, Melin B.
PMID: 34027186
Heliyon. 2021 May 06;7(5):e06989. doi: 10.1016/j.heliyon.2021.e06989. eCollection 2021 May.

It has been demonstrated that the worst performance rule (WPR) effect can occur as a result of statistical dependencies in the data. Here, we examine whether this might also be the case for Spearman's law of diminishing returns (SLODR)....

A comparison of models with weight, height, and BMI as predictors of mortality.

Obesity science & practice

Sorjonen K, Nilsonne G, Falkstedt D, Hemmingsson T, Melin B, Ingre M.
PMID: 33841886
Obes Sci Pract. 2020 Dec 17;7(2):168-175. doi: 10.1002/osp4.473. eCollection 2021 Apr.

INTRODUCTION: Body mass index (BMI) is a composite variable of weight and height, often used as a predictor of health outcomes, including mortality. The main purpose of combining weight and height in one variable is to obtain a measure...
