Testing the cognitive-behavioral model of prolonged grief disorder (PGD): distinct and shared pathways to PTSD and depression.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundThe cognitive-behavioral model of prolonged grief [1] posits that the interaction between autobiographical memory deficits, negative cognitions, and avoidance contributes to the onset and persistence of prolonged grief. This study tested the model's assumptions with respect to symptoms of Prolonged Grief Disorder (PGD), Post-Traumatic Stress Disorder (PTSD), and depression in bereaved groups who experienced expected and unexpected loss, separately.
methodsThe study sample comprised 728 Turkish individuals who had lost a first-degree family member. A set of self-report measures was administered to participants, including the Prolonged Grief Disorder Scale (PG-13-Revised), the Posttraumatic Stress Disorder Checklist for DSM-5 (PCL-5), the Patient Health Questionnaire-9 (PHQ-9), the Grief Cognitions Questionnaire (GCQ-SF), the Depressive and Anxious Avoidance in Prolonged Grief Questionnaire (DAAPGQ), and the Experienced Unrealness Scale (EUS).
resultsOur findings indicate that while variables within the cognitive-behavioral model exhibit moderate to strong intercorrelations, they nonetheless represent statistically distinct constructs. These variables significantly explain the variance in symptoms of PTSD, depression, particularly PGD, in groups confronted with expected and unexpected loss. While negative cognitions and avoidance were significantly associated with all three outcomes, "a sense of unrealness" (representing autobiographical memory deficits) was significantly related only to PGD.
conclusionThese results support the cross-cultural applicability of the cognitive-behavioral model and suggest that it can be used to explain the development of grief-related outcomes, such as PTSD and depression, beyond PGD symptoms. Although the cognitive model variables negative grief cognition and avoidance showed significant associations with grief-related outcomes, a sense of unrealness appeared to be specific to PGD only. It is considered that taking this finding into account in clinical practice may be beneficial.
