Positive, negative and disorganised psychotic symptom dimensions are associated with clinical and developmental variables, but differing definitions complicate interpretation. Additionally, some variables have had little investigation.

To investigate associations of psychotic symptom dimensions with clinical and developmental variables, and familial aggregation of symptom dimensions, in multiple samples employing the same definitions.

We investigated associations between lifetime symptom dimensions and clinical and developmental variables in two twin and two general psychosis samples. Dimension symptom scores and most other variables were from the Operational Criteria Checklist. We used logistic regression in generalised linear mixed models for combined sample analysis (n = 875 probands). We also investigated correlations of dimensions within monozygotic (MZ) twin pairs concordant for psychosis (n = 96 pairs).

Higher symptom scores on all three dimensions were associated with poor premorbid social adjustment, never marrying/cohabiting and earlier age at onset, and with a chronic course, most strongly for the negative dimension. The positive dimension was also associated with Black and minority ethnicity and lifetime cannabis use; the negative dimension with male gender; and the disorganised dimension with gradual onset, lower premorbid IQ and substantial within twin-pair correlation. In secondary analysis, disorganised symptoms in MZ twin probands were associated with lower premorbid IQ in their co-twins.

These results confirm associations that dimensions share in common and strengthen the evidence for distinct associations of co-occurring positive symptoms with ethnic minority status, negative symptoms with male gender and disorganised symptoms with substantial familial influences, which may overlap with influences on premorbid IQ.

Clinicians often rely on caregiver proxy symptom reports to treat cancer-related symptoms in children. Research has described disagreement between children’s and caregivers’ symptom reports. Factors influencing the level of agreement is an understudied area. Thus, this study aimed to examine potential factors contributing to the level of agreement between symptom reports provided by children and their caregivers.

Sixteen child–caregiver dyads participated separately in semi-structured interviews after completing a brief symptom measure independently using an electronic device. Child and caregiver quantitative symptom responses were reviewed in real-time and incorporated into the semi-structured interview. Sample characteristics and the level of agreement between symptom reports were calculated using descriptive statistics. Transcribed participant interviews were analyzed using content analysis.

Nearly half of child–caregiver dyads exhibited a moderate (37.5%, n = 6) or low (18.75%, n = 3) level of agreement on the abbreviated symptom measure. Qualitative analysis identified 5 themes: recognizing symptoms, experiencing symptoms, communicating symptoms, re-assessing and treating symptoms, and influencing individual and relationship factors. Influencing individual, including a child’s tendencies or personality traits, and relationship factors intersected the other themes, partially explained their symptom perceptions, and served to facilitate or hinder symptom communication.

Symptom communication is an important part of the symptom cycle, comprised of symptom recognition, experience, and management. Individual and relational factors may influence discrepancies in symptom perceptions between the child and caregiver. Clinicians and researchers should consider developing interventions to enhance symptom communication and promote collaboration between children and their caregivers to address symptom suffering during cancer treatment.

Compassion is essential in palliative care; however, there is a lack of evidence of the association between this construct and patients’ dignity-related distress. The present study aimed to investigate the association between end-of-life cancer patients’ sense of dignity, the level of compassion of the healthcare professionals (HCPs) noticed and perceived by the patients, and levels of compassion that HCPs felt they had toward patients, investigating through specific attitudes and behaviors. Furthermore, the relationship between compassion and patients’ physical and psychological symptoms, such as levels of anxiety and depression, was also investigated.

The study was cross-sectional. The sample consisted of 105 end-of-life cancer patients and 40 HCPs. Patients had a Karnofsky Performance Status of 50 or lower and a life expectancy of less than 4 months. For each patient, sociodemographic data were collected, and a set of rating scales assessing compassion, dignity as well as physical and psychological symptoms were administered.

The results showed significant negative associations between patients’ perception of compassion and dignity-related distress as well as significant negative associations between patients’ perception of compassion and patients’ symptoms.

Compassion seems to be involved in diminishing dignity-related distress and alleviating physical and psychological symptoms. Other studies are needed to understand whether patients’ symptoms or whether specific HCPs’ conditions influence compassion. Exploring compassion and at the end-of-life could encourage a dignity-conserving care.
