Objective: Religious delusions (RDs) tend to occur relatively often in patients with affective or non‐affective psychosis. Few studies exist about RDs in later life. The current study explores (1) the distribution of RDs across diagnosis, (2) how RDs relate to other types of delusions, and (3) how RDs relate to several dimensions or characteristics of delusions.Methods: Inpatients and outpatients in a Geriatric Psychiatry Department in the Netherlands (N = 155; mean age 76.5 years), and who were diagnosed with an affective or non‐affective psychotic disorder, participated in semi structured diagnostic interviews, using the Schedules for Clinical Assessement in Neuropsychiatry 2.1.Results: Religious delusions were most common among patients with psychotic depression (47%) and schizophrenia (32%). The RDs frequently co‐occurred with other types of delusions. When combined with delusions of grandeur, RDs were more often classified as bizarre and were accompanied by higher levels of positive psychotic symptoms. When combined with delusions of guilt, RDs were associated with higher levels of distress and a shorter disease duration. The delusional characteristics bizarreness, frequency of psychotic symptoms, and degree of distress were more prevalent for RDs than for any other type of delusion.Conclusions: The current study suggests that the prevalence of RDs in older adults is particularly high in late life psychotic depression. Also, in later life, RDs can be perceived of as independent marker of complex psychotic states, and as a denominator of severe arousal with respect to existential concerns.

Background. Although religious delusions (RDs) are common in geriatric psychiatry, we know little about their frequency and content. Our study examines the prevalence and content of religious hallucinations (RHs) and RDs and how they relate to the diagnosis and the patients’ denominational background and other aspects of religiousness. Methods. Semi-structured diagnostic interviews were conducted with inpatients and outpatients (N = 155, mean age 76.5) at a geriatric psychiatry department in the Netherlands. We used the Schedules for Clinical Assessment in Neuropsychiatry 2.1. Results. The prevalences of RHs and RDs were 19% and 32%, respectively. RHs were mostly auditory. There was no statistically significant difference between the prevalence of RHs in schizophrenia (17.5%) and in psychotic depression (9.4%). Compared to non-affiliated patients and mainline Protestants, RDs were significantly more prevalent in raised and current strict Protestants, especially in those with psychotic depression. RHs were more prevalent in Evangelical (e.g., Pentecostal) and strict Protestant patients. The presence of RDs was associated with several measures of religiousness (e.g., dogmatism, religious coping). Conclusions. Religion is likely to act as a symptom-formation factor for psychotic symptoms in strict Protestant older adults. More detailed research might lead to a fuller understanding of how strict religious beliefs may affect the content of psychotic symptoms and unintentionally add a component of existential suffering. It is important for mental health professionals, especially the predominantly secular professionals in the Netherlands, to recognize and address religious themes.

Clergy members (CMs) frequently offer support and counselling for people with mental health problems. The current study aims to obtain insight into the ability among CMs to recognise psychopathology and need for psychiatric treatment. A random sample of CMs (N = 143) and a control sample of mental health professionals (MHPs, N = 73), were compared as to their evaluations of four vignettes. CMs considered the psychiatric states to be related to religious or spiritual problems to a similar degree as they did for the non-psychiatric states. Sensitivity of CMs with regard to the need of psychiatric care for the psychiatric states was modest (66%) and differed significantly from MHPs (96%). Specificity of the CMs was 89%, which was significantly lower than the MHPs (97%). The CMs did recognise psychopathology with religious content but clearly to a lower extent than MHPs. Requests by CMs for education about recognising psychopathology may be considered as justified.

Objective: The course over time of religious delusions (RDs) in late-life schizophrenia and psychotic depression may be relevant to know how long certain aspects of RDs may affect treatment. The present study examines (1) the 1-year follow-up of RDs and other prevalent delusions, (2) the association between RDs and the clinical course of psychotic depression and schizophrenia compared to those without RDs, and (3) associations of RDs and other prevalent delusions with “indicators of complexity” (e.g., suicidality, refusing medication). Design: Prospective study (half year and 1-year follow-up combined). Setting: Outpatients and inpatients in Geriatric Psychiatry Institution of Yulius, South-Holland, the Netherlands. Participants: One hundred and thirty seven older adult patients, mean age 76.3 (s.d. 8.1). Intervention: Natural follow-up study. Measurements: Diagnostic interview measures included Schedules for Clinical Assessment in Neuropsychiatry (SCAN 2.1), positive psychosis items of the Community Assessment of Psychic Experiences-42 (CAPE), and the 20-item measures from the Centre for Epidemiologic Studies Depression Scale (CES-D). Results: Although RDs in older adults decline in the clinical course of psychotic depression, the course is unfavorable compared to psychotic depression without RDs with regard to depressive symptom severity as measured by CES-D. No significant differences were noted in relation to clinical course of positive psychotic symptoms for both psychotic depression and schizophrenia. In schizophrenia, RDs persist more frequently compared to the most prevalent delusions. No significant difference was observed between patients with RDs compared to patients without RDs regarding indicators of clinical complexity. Conclusions: RDs predicting a less favorable course over time in psychotic depression. In schizophrenia, RDs appears to be relatively pervasive.
