Perspective of patients with first-episode psychosis, their relatives, and mental health professionals on the design and usability of an app in clinical practice.

AIM: Therapeutic non-compliance remains the main difficulty for people with psychotic disorders, standing around 50% in people with schizophrenia. Lack of treatment adherence, either partial or total, to medication has economic and clinical consequences. E-health technologies may be a promising therapeutic tool to improve adherence, with the subsequent reduction in clinical and economic burden. Our aims were to know the preferences on how technologies in mental health treatment should be for use in clinical practice, and to learn about the opinion and preferences on the use of technologies in mental health treatment from the perspectives of patients with FEP, their relatives, and mental health professionals. METHODS: Forty-one patients with a diagnosis of first-episode psychosis (FEP), 18 relatives and 49 mental health professionals were included in the study. They completed an online survey related to the use, availability and user-skill of online platforms and apps created by a group of experts in psychosis and in the use of technologies. Data were summarized in frequencies, percentages, and means, and Chi-square tests were used to calculate differences between-groups. RESULTS: An app directed to people with psychosis would be well received by users if it contains psychoeducational material, offers reminders for scheduled visits and treatment and allows online consultations. CONCLUSIONS: Co-creating an app with users, their families and mental health professionals allows incorporating their preferences to increase its use, improve outpatient care and creating an app that is viable in clinical practice.

Identification of the most vulnerable populations in the psychosocial sphere: a cross-sectional study conducted in Catalonia during the strict lockdown imposed against the COVID-19 pandemic.

DESIGN AND OBJECTIVES: A cross-sectional study to evaluate the impact of COVID-19 on the psychosocial sphere in both the general population and healthcare workers (HCWs). METHODS: The study was conducted in Catalonia (Spain) during the first wave of the COVID-19 pandemic when strict lockdown was in force. The study population included all people aged over 16 years who consented to participate in the study and completed the survey, in this case a 74-question questionnaire shared via social media using snowball sampling. A total of 56 656 completed survey questionnaires were obtained between 3 and 19 April 2020.The primary and secondary outcome measures included descriptive statistics for the non-psychological questions and the psychological impact of the pandemic, such as depression, anxiety, stress and post-traumatic stress disorder question scores. RESULTS: A n early and markedly negative impact on family finances, fear of working with COVID-19 patients and ethical issues related to COVID-19 care among HCWs was observed. A total of seven target groups at higher risk of impaired mental health and which may therefore benefit from an intervention were identified, namely women, subjects aged less than 42 years, people with a care burden, socioeconomically deprived groups, people with unskilled or unqualified jobs, patients with COVID-19 and HCWs working with patients with COVID-19. CONCLUSIONS: Active implementation of specific strategies to increase resilience and to prepare an adequate organisational response should be encouraged for the seven groups identified as high risk and susceptible to benefit from an intervention. TRIAL REGISTRATION NUMBER: NCT04378452.

Three-factor model of premorbid adjustment in a sample with chronic schizophrenia and first-episode psychosis.

BACKGROUND: The dimensionality of premorbid adjustment (PA) has been a debated issue, with attempts to determine whether PA is a unitary construct or composed of several independent domains characterized by a differential deterioration pattern and specific outcome correlates. AIMS: This study examines the factorial structure of PA, as well as, the course and correlates of its domains. METHOD: Retrospective study of 84 adult patients experiencing first-episode psychosis (FEP) (n=33) and individuals with schizophrenia (SCH) (n=51). All patients were evaluated with a comprehensive battery of instruments including clinical, functioning and neuropsychological variables. A principal component analysis accompanied by a varimax rotation method was used to examine the factor structure of the PAS-S scale. Paired t tests and Wilcoxon rank tests were used to assess the changes in PAS domains over time. Bivariate correlation analyses were performed to analyse the relationship between PAS factors and clinical, social and cognitive variables. RESULTS: PA was better explained by three factors (71.65% of the variance): Academic PA, Social PA and Socio-sexual PA. The academic domain showed higher scores of PA from childhood. Social and clinical variables were more strongly related to Social PA and Socio-sexual PA domains, and the Academic PA domain was exclusively associated with cognitive variables. CONCLUSION: This study supports previous evidence, emphasizing the validity of dividing PA into its sub-components. A differential deterioration pattern and specific correlates were observed in each PA domains, suggesting that impairments in each PA domain might predispose individuals to develop different expressions of psychotic dimensions.

Cognitive correlates of verbal memory and verbal fluency in schizophrenia, and differential effects of various clinical symptoms between male and female patients.

BACKGROUND: Impairment of higher cognitive functions in patients with schizophrenia might stem from perturbation of more basic functions, such as processing speed. Various clinical symptoms might affect cognitive efficiency as well. Notably, previous research has revealed the role of affective symptoms on memory performance in this population, and suggested sex-specific effects. METHOD: We conducted a post-hoc analysis of an extensive neuropsychological study of 88 patients with schizophrenia. Regression analyses were conducted on verbal memory and verbal fluency data to investigate the contribution of semantic organisation and processing speed to performance. The role of negative and affective symptoms and of attention disorders in verbal memory and verbal fluency was investigated separately in male and female patients. RESULTS: Semantic clustering contributed to verbal recall, and a measure of reading speed contributed to verbal recall as well as to phonological and semantic fluency. Negative symptoms affected verbal recall and verbal fluency in the male patients, whereas attention disorders affected these abilities in the female patients. Furthermore, depression affected verbal recall in women, whereas anxiety affected it in men. CONCLUSIONS: These results confirm the association of processing speed with cognitive efficiency in patients with schizophrenia. They also confirm the previously observed sex-specific associations of depression and anxiety with memory performance in these patients, and suggest that negative symptoms and attention disorders likewise are related to cognitive efficiency differently in men and women.

Spanish validation of the Premorbid Adjustment Scale (PAS-S).

BACKGROUND: The Premorbid Adjustment Scale (PAS) has been the most widely used scale to quantify premorbid status in schizophrenia, coming to be regarded as the gold standard of retrospective assessment instruments. AIMS: To examine the psychometric properties of the Spanish version of the PAS (PAS-S). METHOD: Retrospective study of 140 individuals experiencing a first episode of psychosis (n=77) and individuals who have schizophrenia (n=63), both adult and adolescent patients. Data were collected through a socio-demographic questionnaire and a battery of instruments which includes the following scales: PAS-S, PANSS, LSP, GAF and DAS-sv. The Cronbach's alpha was performed to assess the internal consistency of PAS-S. Pearson's correlations were performed to assess the convergent and discriminant validity. RESULTS: The Cronbach's alpha of the PAS-S scale was 0.85. The correlation between social PAS-S and total PAS-S was 0.85 (p<0.001); while for academic PAS-S and total PAS-S it was 0.53 (p<0.001). Significant correlations were observed between all the scores of each age period evaluated across the PAS-S scale, with a significance value less than 0.001. There was a relationship between negative symptoms and social PAS-S (0.20, p<0.05) and total PAS-S (0.22, p<0.05), but not with academic PAS-S. However, there was a correlation between academic PAS-S and general subscale of the PANSS (0.19, p<0.05). Social PAS-S was related to disability measures (DAS-sv); and academic PAS-S showed discriminant validity with most of the variables of social functioning. PAS-S did not show association with the total LSP scale (discriminant validity). CONCLUSION: The Spanish version of the Premorbid Adjustment Scale showed appropriate psychometric properties in patients experiencing a first episode of psychosis and who have a chronic evolution of the illness. Moreover, each domain of the PAS-S (social and academic premorbid functioning) showed a differential relationship to other characteristics such as psychotic symptoms, disability or social functioning after onset of illness.

Depressive comorbidity in personality disorders.

INTRODUCTION: We aimed to investigate the nature of the associations between PD clusters and MDs, functionality and mental health services use. METHODS: This is a case register study of all cases with a diagnosis of PD detected clinically in a well-defined area in the province of Barcelona covered by 7 Community Mental Health Teams. DSM-IV diagnoses were established by fully trained psychiatrists. Data was also gathered on socio-demographic variables; functional status (GAF) and data on use of health resources, using a systematic computerized method. We performed a non-parametric univariate statistical analysis. RESULTS: We found a higher percentage of major depressive disorder (MDD) among cluster C patients (17%), followed by cluster A (10%) and cluster B (9, 8%). As for the comorbidity between PD clusters and dysthymic disorder, we found that the prevalence was higher among cluster B patients (23,7%) than cluster C (20,2%) or cluster A (7,1%). When considering both MDs together, we found the highest prevalence among cluster C patients (36,87%), followed by cluster B (33,5%) and cluster A (17,1%). Cluster A patients showed worse functioning and visited hospitals most. CONCLUSIONS: A high comorbidity between all MDs analyzed and personality disorders was found, being particularly prominent among cluster C PDs.

An empirical study of psychosocial and clinical correlates of delusional disorder: the DELIREMP study.

OBJECTIVE: We aim to describe psychosocial and clinical correlates of delusional disorder (DD) and its types. This approach is important because most knowledge on DD does not come from empirical data collected using a validated systematic research method. METHODS: A cross-sectional study was conducted in a sample of 86 patients fulfilling DSM-IV criteria for DD as established using the SCID-I. Variables were evaluated using a systematic methodology and standardized instruments, and included possible psychosocial risk factors (low socioeconomic status or social isolation, immigration, sensory deficits, older age at onset), family history of psychiatric disorders and premorbid personality (SAP), psychotic psychopathology (PANSS), depressive syndrome (MADRS), global cognitive functioning (MMSE), axis I comorbidity (MINI) and other clinical aspects such as global functionality (GAF), and disability (SDI). A sociodemographic and clinical questionnaire was also completed. RESULTS: The mean age at onset was 39.6 years and 61.6% of the cases were female. The most frequent DD types were persecutory (59.3%) and jealous (22.1%). Nearly 21% had a family history of schizophrenia and 17.4% had DD (significantly higher among those with the jealous subtype). Sixty-four percent had a premorbid personality disorder (38.4% paranoid, 12.8% schizoid). The grandiose type was significantly associated with higher scores on the PANSS positive subscale and the mixed type with lower scores on the PANSS negative subscale. Depression affected 45.3% of subjects (mainly mild depression) and 45.3% had hallucinations (20.9% tactile, 16.3% olfactory), which were more common among somatic cases. The mean MMSE was 27.6±2.5 suggesting a preserved cognitive function. Mean GAF was 63.9±11.3 indicating a moderate degree of disability, which was significantly worse amongst grandiose cases. CONCLUSIONS: This study provides unique empirical and reliable evidence on the real psychosocial, clinical, and psychopathological correlates of DD and its types.

Do needs, symptoms or disability of outpatients with schizophrenia influence family burden?

BACKGROUND: Most needs of outpatients with schizophrenia are met by the family. This could cause high levels of family burden. The objective of this study is to assess the relationship between the patients' needs and other clinical and disability variables and the level of family burden. METHOD: A total sample of 231 randomly selected outpatients with schizophrenia was evaluated with the Camberwell Assessment of Needs, Positive and Negative Syndrome Scale, Global Assessment of Functioning and Disability Assessment Scale. A total of 147 caregivers also answered the objective and subjective family burden questionnaire (ECFOS-II). Correlations between total number of needs and family burden, t tests between presence or absence of need for each domain of family burden and regression models between family burden and needs, symptoms, disability and sociodemographic variables were computed. RESULTS: The number of patients' needs was correlated with higher levels of family burden in daily life activities, disrupted behaviour and impact on caregiver's daily routine. The patients' needs most associated with family burden were daytime activities, drugs, benefits, self-care, alcohol, psychotic symptoms, money and looking after home. In a regression model, a higher number of needs, higher levels of psychopathology and disability, being male and older accounted for higher levels of family burden. CONCLUSION: Patients with schizophrenia with more needs cause greater family burden but not more subjective concerns in family members. The presence of patients' needs (daytime activities, alcohol and drug), severity of psychotic symptoms and disability are related to higher levels of family burden.

Four symptom dimensions in outpatients with schizophrenia.

OBJECTIVE: The aim of this study was to assess the dimensional structure of the Positive and Negative Symptoms Scale (PANSS) to identify the psychopathological profiles of outpatients with schizophrenia. METHOD: Two hundred and thirty-one persons with schizophrenia (DSM-IV criteria) were randomly selected from a register that included all patients under treatment in 5 mental health care centers in Spain. Patients were evaluated with a sociodemographic and clinical questionnaire, the PANSS, the Disability Assessment Scale short version, and the Global Assessment Functioning Scale. A principal component analysis with oblimin rotation was used to examine the factor structure of the PANSS. Different statistical analyses were done to compare the resulting factors with clinical, disability, and social functioning variables. RESULTS: Mean age of patients included was 39.6 years and approximately 65% were male. Four principal components, each of them with eigenvalues greater than 1.5, accounted for 56.22% of the variance. After oblimin rotation, these factors were identified as the Negative (32.48%), Excitement (11.29%), Affective (7.45%), and Positive (5.01%) components. Significant positive correlation between age and the negative dimension was found. Also, we observed significant negative correlations between global assessment functioning and negative and positive dimensions. Total disability was significantly positively related to all dimensions. CONCLUSION: Positive and negative dimensions are common in all principal component analysis results, but we also found affective and excitement dimensions. The present finding suggests that further investigation of symptom dimensions may help to improve symptom-specific treatments; future research should focus on the design of new treatment programs considering these results.

Neurocognitive performance and negative symptoms: are they equal in explaining disability in schizophrenia outpatients?

OBJECTIVE: The aim of this study is to assess if cognitive variables and symptom dimensions can predict disability in a sample of outpatients with schizophrenia. METHOD: A cross-sectional sample of 113 individuals with a diagnosis of schizophrenia (DSM-IV criteria) was selected from a computerized register of five Community Mental Health Centers. Patients were assessed by two trained psychologists, with a neuropsychological battery comprising measures for verbal memory, attention, operative memory and abstraction and flexibility functions. Symptoms were assessed with the Positive and Negative Syndrome Scale (PANSS); a socio-demographic and clinical questionnaire, comprising the Disability Assessment Scale (DAS), was also completed. Test scores were standardized (t scores) to performance of healthy controls. To assess the relationship between clinical and sociodemographic factors and disability and cognitive functioning Pearson's correlation coefficients were computed. In order to establish the predictive capacity of the cognitive, clinical and symptom variables on disability linear regression models were fitted. RESULTS: Mean age of patients was 41.6 years and 68% were male. Higher ratings in the negative dimension were associated with more cognitive deficits. Association with the positive dimension was present but less strong. All disability areas, except for disability in occupational functioning, were partially explained by the negative dimension. Disability in family functioning was also partially explained by attention and number of admissions since onset. CONCLUSION: Negative symptoms are the major source of disability of our sample and are also associated to cognitive functioning. The present findings suggest that further investigation on the mediators between clinical and social outcomes may help to design specific treatments to reduce disability.
