Abstract (Swedish)
Dysexecutive Questionniare (DEX) är ett av de mest vanligt förekommande
skattningsformulären som mäter exekutivt fungerande i vardagen, och administreras oftast till patienter med förvärvad hjärnskada. Eftersom individer med förvärvad hjärnskada riskerar att lida av nedsatt självmedvetenhet av brister i exekutiva funktioner, är skalan tillgänglig både som självskattning och informantskattning. Denna studie rapporterade på validiteten av DEX hos ett urval av individer med tidigare hjärtinfarkt (n = 90) och tidigare hjärtstopp utanför sjukhus (n = 106). Deltagarna och deras informanter fyllde i DEX, medan deltagarna dessutom bedömdes med hjälp av två neuropsykologiska prestationsbaserade mått av exekutiva funktioner och skattade sina symtom...

Denna studie rapporterade på validiteten av DEX hos ett urval av individer med tidigare hjärtinfarkt (n = 90) och tidigare hjärtstopp utanför sjukhus (n = 106). Deltagarna och deras informanter fyllde i DEX, medan deltagarna dessutom bedömdes med hjälp av två neuropsykologiska prestationsbaserade mått av exekutiva funktioner och skattade sina symtom på ångest, depression och trötthet (fatigue).
Det fanns ingen skillnad mellan totalpoängen på helskalenivå mellan självskattningen och informantskattningen, vilket tyder på att deltagarna på gruppnivå inte uppvisar brister i självmedvetenhet. Korrelationsanalyser visade att sambanden mellan självskattningen avDEX och måtten på depression och ångest var stark, medan sambanden med de prestationsbaserade måtten uppnådde signifikans enbart i gruppen med tidigare hjärtstopp. Multipla regressionsanalyser demonstrerade att mått på ångest och depression var signifikanta enskilda prediktorer för självskattningen av DEX, medan de prestationsbaserade måtten inte
blev signifikanta prediktorer i modellerna. Förklarad varians sträckte sig mellan 9–52% beroende på skattare och urval när demografiska variabler hölls konstant. Sammanfattningsvis belyser studien vikten av att validera de psykometriska egenskaperna hos DEX i olika populationer. (Less)
Abstract
The Dysexecutive Questionnaire (DEX) is one of the most commonly used rating scales of executive functioning in daily life and is most frequently administered to patients with acquired brain injury (ABI). Because individuals with ABI are at risk of suffering from impaired self-awareness of executive function deficits, the scale is available both as a self-assessment and in an independent-rating version. This study reported on the validity of the DEX in samples of individuals with a prior myocardial infarction (n = 90) and out-of-hospital cardiac arrest (n = 106). Participants and their informants completed the DEX, while participants were additionally assessed by two neuropsychological assessments of executive functions, and rated their... (More)
The Dysexecutive Questionnaire (DEX) is one of the most commonly used rating scales of executive functioning in daily life and is most frequently administered to patients with acquired brain injury (ABI). Because individuals with ABI are at risk of suffering from impaired self-awareness of executive function deficits, the scale is available both as a self-assessment and in an independent-rating version. This study reported on the validity of the DEX in samples of individuals with a prior myocardial infarction (n = 90) and out-of-hospital cardiac arrest (n = 106). Participants and their informants completed the DEX, while participants were additionally assessed by two neuropsychological assessments of executive functions, and rated their symptoms of anxiety, depression and fatigue. There was no significant difference between total scores of the self- and informant-assessed ratings, suggesting that the participants do not exhibit a lack of self-awareness on group level. Correlational analyses showed that the associations between the self-assessed DEX and measures of depression and anxiety were strong in both groups, while the performance-based measures only reached significance in the participant group with previous cardiac arrest. Multiple regression analyses demonstrated that measures of anxiety and depression were significant individual predictors of total scores on the self-assessment of the DEX, while the performance-based assessments were not significant. Explained variance between the models ranged between 9-52% depending on raters and sample when demographic variables were held constant. In conclusion, the study highlights the importance of validating the psychometric properties of the DEX in a variety of populations. (Less)
