Correlation between duration of untreated psychosis and long-term prognosis in chronic schizophrenia

OBJECTIVE

To explore the relationship between the Duration of Untreated Psychosis (DUP) and long-term clinical outcome, cognitive and social function in patients with chronic schizophrenia (SCZ).

METHODS

A total of 248 subjects with chronic SCZ were enrolled in this study, including 156 in the short DUP group and 92 in the long DUP group. The Positive and Negative Symptoms Scale (PANSS), the Brief Negative Symptoms Scale (BNSS), the Global Assessment of Functioning (GAF) scale and the Repeatable Battery for the Assessment of Neuropsychological Status (RBANS) were used to assess all of the subjects.

RESULTS

The negative symptom scores (the PANSS and BNSS) of subjects with long DUP were significantly higher than that in subjects with short DUP. The scores of visual span and speech function in the short DUP group were significantly higher, indicative of decreasing cognitive function with time. In terms of social function, the short DUP group scored higher, with a statistically significant difference. Meanwhile, we found that the length of DUP was positively correlated with the negative symptom score of the PANSS, negatively correlated with visual span scores, and GAF scores.

CONCLUSION

This study demonstrated that the DUP remained a significant association with negative symptom and cognition in long period of chronic SCZ.

Primary Psychosis: Risk and Protective Factors and Early Detection of the Onset

Primary psychosis, which includes schizophrenia and other psychoses not caused by other psychic or physical conditions, has a strong impact worldwide in terms of disability, suffering and costs. Consequently, improvement of strategies to reduce the incidence and to improve the prognosis of this disorder is a current need. The purpose of this work is to review the current scientific literature on the main risk and protective factors of primary psychosis and to examine the main models of prevention, especially those related to the early detection of the onset. The conditions more strongly associated with primary psychosis are socio-demographic and economic factors such as male gender, birth in winter, ethnic minority, immigrant status, and difficult socio-economic conditions while the best-established preventive factors are elevated socio-economic status and an economic well-being. Risk and protective factors may be the targets for primordial, primary, and secondary preventive strategies. Acting on modifiable factors may reduce the incidence of the disorder or postpone its onset, while an early detection of the new cases enables a prompt treatment and a consequential better prognosis. According to this evidence, the study of the determinants of primary psychosis has a pivotal role in designing and promoting preventive policies aimed at reducing the burden of disability and suffering of the disorder.

Associations between duration of untreated psychosis and domains of positive and negative symptoms

AIM

The duration of untreated psychosis (DUP) has been established as an independent and significant predictor of negative outcomes in first-episode psychosis samples. Whereas literature has supported the association between DUP and severity of positive and negative symptoms, surprisingly little research to date has explored specifically what types of positive and negative symptoms are most associated with DUP.

METHODS

DUP, Scale for the Assessment of Positive Symptoms (SAPS) and Scale for the Assessment of Negative Symptoms (SANS) data were collected in 247 first-episode psychosis participants (mean age: 23.9 ± 4.8) between August 2008 and June 2013.

RESULTS

DUP was significantly but modestly associated with the severity of hallucinations (ρ = 0.222; P = 0.001), delusions (r = 0.202; P = 0.003) and formal thought disorder (ρ = 0.138; P = 0.043) but was not associated with bizarre behaviour. DUP was significantly but modestly associated with SANS avolition-apathy (ρ = 0.164; P = 0.016) and anhedonia-asociality (r = 0.321; P < 0.001) subscales but was not associated with affective flattening or blunting, alogia or attention.

CONCLUSIONS

DUP is a complex and multifaceted phenomenon that is associated with early-course illness development. In efforts to improve early intervention services, prognoses and outcomes, it is vital to understand both the factors that contribute to lengthy untreated psychosis as well as the illness characteristics that are impacted by untreated psychosis.

Impact of online resources and social media on help-seeking behaviour in youth with psychotic symptoms

AIM

The objective of the study was to explore the content of existing online resources available to information-seeking youth as psychotic symptoms first emerge and determine how these resources may influence initiation of care.

METHODS

Using 18 hypothetical search terms, developed by the Early Treatment Programme (ETP) staff, we searched three of the most popular websites used by the youth (Google, Facebook and Twitter) and extracted the first five hits from each. Sites were categorized into those that encouraged help seeking, those that potentially contribute to treatment delay, those with an undetermined impact and those that were unrelated to treatment.

RESULTS

An alarmingly few of the first five hits from the top three online resources encourage potentially psychotic youth to seek professional evaluation. The majority of our search results yielded unmonitored chat forums that lacked a unified message. The remainder promoted stigma, normalized potentially psychotic experiences or were completely unrelated to mental health.

CONCLUSION

We must develop innovative, easy-to-access and youth-focused online and social media experiences that encourage symptomatic youth to seek care.

An investigation of duration of untreated psychosis and the affecting factors

One of the main goals in treatment planning of psychiatric disorders is early diagnosis of patients in the early psychosis period so that duration of untreated psychosis (DUP) is decreased and the treatment response and outcome is improved. The aim of this study was to investigate the DUP of psychosis and factors affecting it. In this cross-sectional study, 80 patients from the psychiatric clinic of Fatemi hospital in Ardabil and Razi hospital in Tabriz who were in the first episode of psychosis completed a questionnaire. The data were analysed by SPSS statistical software. In this study, the mean DUP measured from the appearance of the first symptoms of psychosis were 261.3 ± 110.8 and 212.5 ± 143.5 days for patients referring to Razi and Fatemi hospital, respectively. About 65% of the patients in Fatemi hospital and 32.5% of them in Razi hospital considered visiting a psychiatrist as hard and very hard. The DUP mean here was found to be higher as compared with that of the developed countries. The following factors were found to be playing a role in making DUP longer: lower education, implausible beliefs and culturally rooted social stigma status of visiting a psychiatrist.
