Validity, reliability and factor analysis of the Polish version of the Peritraumatic Distress Inventory

Abstract

Cel pracyOcena trafności i rzetelności polskiej wersji Skali Dystresu Okołotraumatycznego oraz przeprowadzenie analizy czynnikowej narzędzia.MetodaPrzekrojowym badaniem objęto 100 pracowników systemu ratownictwa medycznego w Polsce, którzy wypełnili autorską metryczkę, polską wersja Zrewidowanej Skali Wpływu Zdarzeń oraz poddaną walidacji w niniejszym badaniu Skalę Dystresu Okołotraumatycznego (PDI).WynikiWartość współczynnika α Cronbacha dla całej skali, obejmującej ostatecznie 12 itemów, wynosi 0,77. Wykazano 3-czynnikową strukturę narzędzia, która wyjaśnia 60,04% wariancji. Wykonane analizy ujawniły umiarkowane i wysokie wartości ładunków czynnikowych wszystkich pozycji tworzących poszczególne podskale z wyjątkiem pozycji piątej. Na tej podstawie podjęto decyzję o odrzuceniu ze skali itemu piątego. Wartość α- Cronbacha dla czynnika 1 (Utrata kontroli i pobudzenie) wynosi 0,75, czynnika 2 (Emocje negatywne) - 0,77 i dla czynnika 3 (Poczucie zagrożenia) - 0,68. Stwierdzono silną, dodatnią korelację pomiędzy dystresem a nasileniem objawów stresu pourazowego (p<0,01). Dodatkowo dystres silnie i dodatnio korelował z poszczególnymi objawami PTSD: intruzją, pobudzeniem i unikaniem.WnioskiPolska wersja PDI wydaje się być trafnym i rzetelnym narzędziem do oceny dystresu.

Factor analysis and validity of the Polish version of the Peritraumatic Distress Inventory in mothers of seriously ill children

“…Higher scores indicate increased distress. Cronbach's α for the Polish version in the group of Emergency Medical Service workers was 0.77 and was similar to the results obtained in other validation studies (Rybojad & Aftyka, ).…”

“…For example, Boden, Fergusson, Horwood, & Mulder () who examined the group of victims of the earthquake in New Zealand believe that attention should be paid to the subjective reactions of the assessed persons.The usefulness of the tool is confirmed by its validation in several languages and different populations experiencing stress and potentially suffering from PTSD (Bahari, Malek, Japil, Madlan, & Adela Mutang, ; Bui et al.,; Jehel et al., ; Kianpoor et al., ; Nishi et al., ). In Poland, cultural adaptation and PDI validation were performed in a group of employees of the emergency medical system (Rybojad & Aftyka, ). This survey was aimed at conducting PDI factor analysis and validation in a population not yet studied in Poland with the use of this tool.…”

“…In these two studies, no factor analysis was performed (Bahari et al., ; Kianpoor et al., ). Other validations available in the literature (including the Polish version) were based on three factors, similarly to the original PDI (Brunet et al., ; Nishi et al., ; Rybojad & Aftyka, ). In the studied group, Cronbach's α for the 11‐item scale was 0.80, and in the cited surveys, Cronbach's α was between 0.73 (Kianpoor et al., ) and 0.89 (Boden et al., ).…”

“…Validation and reliability of the PDI were originally studied in a volunteer group of policemen and compared to the general population. It is a self‐report tool, useful in the early selection of people at risk of PTSD, validated in several languages (Bui et al., ; Jehel, Brunet, Paterniti, & Guelfi, ; Kianpoor et al., ; Nishi et al., ; Rybojad & Aftyka, ). According to our knowledge resulting from searches in the literature, this study is the first official attempt to validate PDI in the group of mothers of seriously ill children.…”

Peritraumatic distress among emergency medical system employees: A proposed cut-off for the Peritraumatic Distress Inventory

“…Traumatic events were included in the so-called criteria A category, with a requirement of a cause-and-effect relationship between A1 (experience or being a witness to a tragic event) and A2 (a reaction in the form of peritraumatic distress [PD], characterised by fear, a sense of helplessness and horror). Although criterion A2 [6] has been removed from the DSM-V, PD remains a strong predictor of posttraumatic stress symptoms (PTSS) [9]. One of the tools used for clinical evaluation of PTSD is the Peritraumatic Distress Inventory (PDI) [10].…”
