Pathways to psychosis: Help-seeking behavior in the prodromal phase
Open accessAbstract
Background Knowledge of pathways to care by help-seeking patients prior to the onset of psychosis may help to improve the identification of at-risk patients. This study explored the history of help-seeking behavior in secondary mental health care services prior to the onset of the first episode of psychosis. Method The psychiatric case register in The Hague was used to identify a cohort of 1753 people in the age range of 18-35 at first contact who developed a psychotic disorder in the period from 1 January 2005 to 31 December 2009. We retrospectively examined the diagnoses made at first contact with psychiatric services. Results 985 patients (56.2%) had been treated in secondary mental health services prior to the onset of psychosis. The most common disorders were mood and anxiety disorders (N=385 (39.1%)) and substance use disorders (N=211 (21.4%)). Affective psychoses were more often preceded by mood/anxiety disorders, while psychotic disorder NOS was more often preceded by personality disorder or substance abuse. The interval between first contact and first diagnosis of psychosis was approximately 69 months in cases presenting with mood and anxiety disorders and 127 months in cases presenting with personality disorders. Discussion This study confirms the hypothesis that the majority of patients with psychotic disorders had been help-seeking for other mental disorders in the secondary mental health care prior to the onset of psychosis.

The findings related to those with anxiety disorders are relatively unique, given the limited literature on the presentation of paranoia and prodromal symptoms in anxiety disorder populations.
“However, the findings related to those with anxiety disorders are relatively unique, given the limited literature on the presentation of paranoia (Reich & Braginsky, 1994; Taylor & Stopa, 2013) and prodromal symptoms (Rietdijk et al., 2011; Shioiri et al., 2007) in anxiety disorder populations.”

Section 4.1 reports that anxiety and mood disorders were the most common prior diagnoses among patients who later developed psychosis, making this paper relevant to the cited topic. But the study starts with a psychosis cohort and examines its earlier diagnoses; it does not study prodromal-symptom presentation in a population selected for anxiety disorders. The sentence’s characterization of the literature as limited is the citing authors’ framing, not a finding established by this source. (LLM, conf=0.81)

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
