The old psychology

The spate of "new" psychologies with which we were familiar in the nineteen-twenties (to say nothing of the nineteen-tens and the eighteen-nineties) has died down, and psychologists now talk in terms of points of view and preferred concepts rather than party allegiances. Nevertheless, one impression persists which needs to be enquired into. Among those interested in ,the subject, but not themselves psychologists, it takes this form: psychology is in continuous, large scale flux, and is therefore a new-fangled, insecure, aggressive, and rather" gimmicky" field of endeavour. Among psychologists themselves, the assumption is more specific and sophisticated: it is, that psychology became respectable with the rise of experimentalism (with the foundation by Wilhelm Wundt of the laboratory at Leipzig in 1879, if 'an exact date is wanted), and that previous work can be relegated to a species of antiquarian rag-bag, or rubbish-heap of superstition

Policy Document Analysis: A Practical Educational Leadership Tool and a Qualitative Research Method

This paper presents policy document analysis as practical tool that can be put to valuable use by educational leaders and can also be adopted as a research method. Educational leaders are at the forefront of policy interpretation and consequently need knowledge and skills that enable them to analyse policy as part of their work in developing, implementing and reviewing organisational policy. They need to be able to look behind the policy to know what forces brought it into being; to tap into policy history to know how it was constructed; and most importantly, evaluate the way it is working to achieve its stated purposes. The analysis of policy documents is also an established and appealing qualitative research method, especially for students engaged in postgraduate research associated with educational leadership and policy studies because policy documents offer background insights into understanding educational problems in both research and practice. In this paper advantages and disadvantages associated with using documentary analysis as a qualitative research method are outlined and practical document analysis tools and approaches are presented

Is the bark worse than the bite? Additional conditions used within community treatment orders.

Aims and method: To investigate the use of additional conditions attached to community treatment orders (CTOs) and whether they influence the process of recall to hospital. We conducted a retrospective descriptive survey of the records and associated paperwork of all the CTOs started in the trust in the year from January 2010. Each CTO was followed up for 12 months. Results: A total of 65 CTOs were included in the study; 25 patients were recalled during the study and all but one of these had their CTO revoked and remained in hospital. Each patient whose CTO was revoked had experienced a relapse in their condition. Many patients had not complied with CTO conditions prior to relapsing and could potentially have been recalled earlier. Clinical implications: Our findings suggest that the breaching of additional CTO conditions does not tend to result in a patient's recall to hospital. This has implications regarding how the workings of CTOs are explained to patients and regarding the utility of additional conditions more generally

A shared genetic propensity underlies experiences of bullying victimization in late childhood and self-rated paranoid thinking in adolescence

Background: Bullying is a risk factor for developing psychotic experiences (PEs). Whether bullying is associated with particular PEs, and the extent to which genes and environments influence the association, are unknown. This study investigated which specific PEs in adolescence are associated with earlier bullying victimization and the genetic and environmental contributions underlying their association. Method: Participants were 4826 twin pairs from a longitudinal community-based twin study in England and Wales who reported on their bullying victimization at the age of 12 years. Measures of specific PEs (self-rated Paranoia, Hallucinations, Cognitive disorganization, Grandiosity, Anhedonia, and parent-rated Negative Symptoms) were recorded at age of 16 years. Results: Childhood bullying victimization was most strongly associated with Paranoia in adolescence (r = .26; P < .01), with weaker associations with Hallucinations, Cognitive Disorganization, parent-rated Negative Symptoms (r = .12–.20; P < .01), Grandiosity (r = .04; P < .05), and Anhedonia (r = .00, n.s.). Bivariate twin model-fitting demonstrated that bullying victimization and Paranoia were both heritable (35% and 52%, respectively) with unique environmental influences (39% and 48%, respectively), and bullying victimization showed common environmental influences (26%). The association between bullying victimization and Paranoia operated almost entirely via genetic influences (bivariate heritability = 93%), with considerable genetic overlap (genetic correlation = .55). Conclusion: In contrast to the assumed role of bullying victimization as an environmental trigger, these data suggest that bullying victimization in late childhood is particularly linked to self-rated Paranoia in adolescence via a shared genetic propensity. Clinically, individuals with a history of bullying victimization are predicted to be particularly susceptible to paranoid symptoms

A Data-driven Investigation of Relationships Between Bipolar Psychotic Symptoms and Schizophrenia Genome-wide Significant Genetic Loci

The etiologies of bipolar disorder (BD) and schizophrenia include a large number of common risk alleles, many of which are shared across the disorders. BD is clinically heterogeneous and it has been postulated that the pattern of symptoms is in part determined by the particular risk alleles carried, and in particular, that risk alleles also confer liability to schizophrenia influence psychotic symptoms in those with BD. To investigate links between psychotic symptoms in BD and schizophrenia risk alleles we employed a data-driven approach in a genotyped and deeply phenotyped sample of subjects with BD. We used sparse canonical correlation analysis (sCCA) (Witten, Tibshirani, & Hastie, ) to analyze 30 psychotic symptoms, assessed with the OPerational CRITeria checklist, and 82 independent genome-wide significant single nucleotide polymorphisms (SNPs) identified by the Schizophrenia Working group of the Psychiatric Genomics Consortium for which we had data in our BD sample (3,903 subjects). As a secondary analysis, we applied sCCA to larger groups of SNPs, and also to groups of symptoms defined according to a published factor analyses of schizophrenia. sCCA analysis based on individual psychotic symptoms revealed a significant association (p = .033), with the largest weights attributed to a variant on chromosome 3 (rs11411529), chr3:180594593, build 37) and delusions of influence, bizarre behavior and grandiose delusions. sCCA analysis using the same set of SNPs supported association with the same SNP and the group of symptoms defined "factor 3" (p = .012). A significant association was also observed to the "factor 3" phenotype group when we included a greater number of SNPs that were less stringently associated with schizophrenia; although other SNPs contributed to the significant multivariate association result, the greatest weight remained assigned to rs11411529. Our results suggest that the canonical correlation is a useful tool to explore phenotype-genotype relationships. To the best of our knowledge, this is the first study to apply this approach to complex, polygenic psychiatric traits. The sparse canonical correlation approach offers the potential to include a larger number of fine-grained systematic descriptors, and to include genetic markers associated with other disorders that are genetically correlated with BD

Consistent etiology of severe, frequent psychotic experiences and milder, less frequent manifestations: a twin study of specific psychotic experiences in adolescence

- Importance: The onset of psychosis is usually preceded by psychotic experiences (PE). Little is known about the etiology of PE and whether the degree of genetic and environmental influences varies across different levels of severity. A recognized challenge is to identify individuals at high risk of developing psychotic disorders prior to disease onset. - Objectives: To investigate the degree of genetic and environmental influences on specific PE, assessed dimensionally, in adolescents in the community and in those who have many, frequent experiences (defined using quantitative cutoffs). We also assessed the degree of overlap in etiological influences between specific PE. - Design, Setting, and Participants: Structural equation model-fitting, including univariate and bivariate twin models, liability threshold models, DeFries-Fulker extremes analysis, and the Cherny method, was used to analyze a representative community sample of 5059 adolescent twin pairs (mean [SD] age, 16.31 [0.68] years) from England and Wales. - Main Outcomes and Measures: Psychotic experiences assessed as quantitative traits (self-rated paranoia, hallucinations, cognitive disorganization, grandiosity, and anhedonia, as well as parent-rated negative symptoms). - Results: Genetic influences were apparent for all PE (15%-59%), with modest shared environment for hallucinations and negative symptoms (17%-24%) and significant nonshared environment (49%-64%) for the self-rated scales and 17% for parent-rated negative symptoms. Three empirical approaches converged to suggest that the etiology in extreme-scoring groups (most extreme scoring: 5%, 10%, and 15%) did not differ significantly from that of the whole distribution. There was no linear change in heritability across the distribution of PE, with the exception of a modest increase in heritability for increasing severity of parent-rated negative symptoms. Of the PE that showed covariation, this appeared to be due to shared genetic influences (bivariate heritabilities, 0.54-0.71). - Conclusions and Relevance: These findings are consistent with the concept of a psychosis continuum, suggesting that the same genetic and environmental factors influence both extreme, frequent PE and milder, less frequent manifestations in adolescents. Individual PE in adolescence, assessed quantitatively, have lower heritability estimates and higher estimates of nonshared environment than those for the liability to schizophrenia. Heritability varies by type of PE, being highest for paranoia and parent-rated negative symptoms and lowest for hallucinations

Heritability of Individual Psychotic Experiences Captured by Common Genetic Variants in a Community Sample of Adolescents.

Occurrence of psychotic experiences is common amongst adolescents in the general population. Twin studies suggest that a third to a half of variance in adolescent psychotic experiences is explained by genetic influences. Here we test the extent to which common genetic variants account for some of the twin-based heritability. Psychotic experiences were assessed with the Specific Psychotic Experiences Questionnaire in a community sample of 2152 16-year-olds. Self-reported measures of Paranoia, Hallucinations, Cognitive Disorganization, Grandiosity, Anhedonia, and Parent-rated Negative Symptoms were obtained. Estimates of SNP heritability were derived and compared to the twin heritability estimates from the same sample. Three approaches to genome-wide restricted maximum likelihood (GREML) analyses were compared: (1) standard GREML performed on full genome-wide data; (2) GREML stratified by minor allele frequency (MAF); and (3) GREML performed on pruned data. The standard GREML revealed a significant SNP heritability of 20 % for Anhedonia (SE = 0.12; p < 0.046) and an estimate of 19 % for Cognitive Disorganization, which was close to significant (SE = 0.13; p < 0.059). Grandiosity and Paranoia showed modest SNP heritability estimates (17 %; SE = 0.13 and 14 %; SE = 0.13, respectively, both n.s.), and zero estimates were found for Hallucinations and Negative Symptoms. The estimates for Anhedonia, Cognitive Disorganization and Grandiosity accounted for approximately half the previously reported twin heritability. SNP heritability estimates from the MAF-stratified approach were mostly consistent with the standard estimates and offered additional information about the distribution of heritability across the MAF range of the SNPs. In contrast, the estimates derived from the pruned data were for the most part not consistent with the other two approaches. It is likely that the difference seen in the pruned estimates was driven by the loss of tagged causal variants, an issue fundamental to this approach. The current results suggest that common genetic variants play a role in the etiology of some adolescent psychotic experiences, however further research on larger samples is desired and the use of MAF-stratified approach recommended

‘Like I said about culture. You don't talk about mental health’: An interpretative phenomenological analysis of the experience of first-episode psychosis in South Asian individuals

Background There is strong evidence of inequalities in mental healthcare access, experiences and outcomes for service users belonging to Black and Asian Minority Ethnic groups experiencing psychosis. Clinicians and academics have speculated that cultural variation in conceptualisations of psychosis, alongside inequitable service provision may explain disparities. There is, however, a dearth of literature exploring this in a South Asian population, despite this ethnic group being the second largest in the United Kingdom. The present study aimed to explore how people from this minority group have experienced and made sense of first-episode psychosis (FEP). Methods A qualitative approach was used to explore the lived experience and sense-making of South Asian individuals experiencing FEP and accessing early intervention services. Eight people were interviewed using a semi-structured format. The data were analysed using Interpretative Phenomenological Analysis. Results Three superordinate themes were identified in the group analysis: (1) Disconnection from self and others (2) Doubt and dispute (3) Power and shame. Conclusions Distinctive ethnic, cultural and systemic influences were strongly evident in how people conceptualized their experiences, how they managed their sense-making and where they sought support. Experiences were discussed in the context of power and shame, and this research proposes that socio-cultural context and racialised discourses have an impact on self-concept, the experiences of help-seeking (formal and informal), and fundamentally how services help individuals from marginalized communities
