V magistrskem delu smo validirali slovenski prevod Vprašalnika o razpoloženjskih simptomih in anksioznosti (MASQ), ki je bil oblikovan na podlagi Clark-Watsonovega tripartitnega modela anksioznosti in depresivnosti. Skladno s tem modelom lahko razpoloženjske simptome razdelimo v 3 skupine, in sicer 1) nespecifične simptome splošnega distresa (lestvica MASQ-GD), ki so značilni tako za anksioznost kot depresivnost, 2) fiziološko vzburjenje (lestvica MASQ-AA), ki je specifično za anksioznost, in 3) anhedonijo oz. nizek pozitivni afekt (lestvica MASQ-AD), značilen samo za depresivnost. V vzorec so bili vključeni pacienti Univerzitetne psihiatrične klinike Ljubljana z blažjimi, zmernimi ali hudimi simptomi depresivnosti ali anksioznosti. Udeleženci so v spletnem okolju za izvedbo eksperimentov Pavlovia poleg vprašalnika MASQ izpolnili še Lestvico generalizirane anksioznosti GAD-7 in lestvico depresivnosti Vprašalnik o bolnikovem zdravju PHQ-9. Psihometrično analizo smo izvedli s pomočjo računalniškega programa R. Povprečni dosežki na lestvicah MASQ-GD in MASQ-AD ter klasični skupni dosežek vprašalnika MASQ so bili srednje visoki, povprečni dosežek na lestvici MASQ-AA pa je bil nizek. Porazdelitev odgovorov ni bila normalna pri nobeni izmed lestvic, prav tako se je nenormalno porazdeljeval klasični skupni dosežek vprašalnika MASQ. Korelacije med dosežki na lestvicah vprašalnika MASQ so bile skladne s predpostavkami tripartitnega modela. Korelaciji med dosežki na lestvicah MASQ-GD in MASQ-AA ter MASQ-GD in MASQ-AD sta bili visoki, korelacija med dosežki na lestvicah MASQ-AA in MASQ-AD pa je bila zmerna. Koeficienti notranje skladnosti λ2 so pokazali odlično zanesljivost lestvic MASQ-GD in MASQ-AA, dobro zanesljivost lestvice MASQ-AD in odlično zanesljivost kompozitnega dosežka MASQ77. Faktorska analiza je pokazala ustrezno prileganje modela podatkom. Korelacije med dosežki na vprašalnikih MASQ, GAD-7 in PHQ-9 so bile pričakovano visoke, faktorska analiza pa je pokazala, da je izmed 3 alternativnih strukturnih modelov najboljši model splošni distres, ki predpostavlja, da vprašalnika PHQ-9 in GAD-7 skupaj merita isti konstrukt kot lestvica MASQ-GD. Na podlagi izvedene psihometrične analize lahko zaključimo, da ima slovenski prevod vprašalnika MASQ ustrezne psihometrične značilnosti in je primeren za raziskovalno uporabo na slovenski klinični populaciji.

• Title: Validation of the Mood and Anxiety Symptom Questionnaire (MASQ)

Abstract

In the master's thesis, we validated the Slovenian translation of the Mood and Anxiety Symptom Questionnaire (MASQ), which was created on the basis of Clark and Watson's tripartite model of anxiety and depression. According to this model, symptoms of mood disorders can be divided into 3 groups: 1) non-specific symptoms of general distress (as measured by MASQ-GD scale), which are characteristics of both anxiety and depression, 2) physiological arousal (MASQ-AA scale), which is specific to anxiety, and 3) anhedonia or low positive affect (MASQ-AD scale), which is specific to depression. Patients of the University Psychiatric Clinic Ljubljana with mild, moderate or severe symptoms of depression or anxiety were included in the sample. In addition to the MASQ, participants completed the Generalized Anxiety Scale (GAD-7) and a depression scale, the Patient Health Questionnaire (PHQ-9) in the Pavlovia online experiment environment. Psychometric analysis was performed using R software. The average scores on the MASQ-GD and MASQ-AD scales and the classical sum-score of the MASQ questionnaire were medium, while the average score on the MASQ-AA scale was low. The distribution of scores was not normal for any of the scales and the classical sum-score of the MASQ questionnaire as well. Correlations between scores on the MASQ questionnaire were consistent with the assumptions of the tripartite model. The correlation between achievements on the MASQ-GD and MASQ-AA scales was high and the correlation between MASQ-GD and MASQ-AD scales was high. The correlation between achievements on the MASQ-AA and MASQ-AD scales were moderate. Internal consistency coefficients λ2 showed excellent reliability of the scales MASQ-GD and MASQ-AA, good reliability of the scale MASQ-AD and excellent composite reliability of the MASQ77. Factor analysis confirmed an adequate fit of the model to the data. Correlations between achievements on the MASQ, GAD-7 and PHQ-9 questionnaires were expectedly high and the factor analysis confirmed that the best among 3 alternative structural models was the model “general distress”, which assumed that the GAD-7 and PHQ-9 measure the same latent construct as the MASQ-GD scale. Based on the psychometric analysis performed, we can conclude that the Slovenian translation of the MASQ questionnaire has adequate psychometric characteristics and is suitable for use in the Slovenian clinical population.
