BMC Psychiatry , 2013, DOI: 10.1186/1471-244x-13-48
Abstract: A participatory approach was chosen for instrument development which followed 10 sequential steps proposed in a current guideline of good practice for the translation and cultural adaptation of measures. Following item analysis, reliability, validity, and long-term stability of the CDMS were examined using Spearman correlations in a sample of 588 people with severe mental illness and 213 mental health professionals in 6 European countries (Germany, UK, Italy, Denmark, Hungary, and Switzerland).In both patient and staff versions, the two CDMS subscales “Participation in Decision Making” and “Information” reliably measure distinct characteristics of decision making. Validity could be demonstrated to some extent, but needs further investigation.Together with two other five-language patient- and staff-rated measures developed in the CEDAR study (ISRCTN75841675) – “Clinical Decision Making in Routine Care” and “Clinical Decision Making Involvement and Satisfaction” – the CDMS allows empirical investigation of the complex relation between clinical decision making and outcome in the treatment of people with severe mental illness across Europe.Decision-making in health care has been conceptualized as a process taking place between patient and health professional on a continuum between “paternalistic”, “shared”, and “informed” [1,2]. Shared decision making has received much attention in research and practice since its first mention 30 years ago [3]. Substantial evidence has accumulated in recent decades for clinical decision making in acute (e.g. heart attack, stroke) and long-term physical conditions (e.g. cancer and fibromyalgia) [4-10]. Shared decision making has been termed an ethical imperative [11] and is recommended in guidelines for the treatment of people with schizophrenia [12].However, knowledge about clinical decision making in the treatment of people with mental illness is still limited. Most importantly, apart from a few studies [13], little is known about the

Abstract: The aim of this study was to determine the psychometric properties of a measurement instrument design for the evaluation of the occupational positive mental health. Based on the positive psychology, humanism, salutogenesis and ecological model, we developed a 40 items survey with a five-point Liker response option. A sample of 740 workers of different occupations answered the survey, taking an average of 15 minutes. The data analysis included exploratory factor analysis for the determination of factorial validity and Cronbach’s Alpha coefficient for reliability. The results indicated a four-factor structure that explains 43.55% of the total variance and a Cronbach’s Alpha of .923 for the whole instrument. We conclude that the SMPO-40 is a valid and reliable measurement instrument for the evaluation of the occupational positive mental health.
Development of mental health quality indicators (MHQIs) for inpatient psychiatry based on the interRAI mental health assessment  [cached]

BMC Health Services Research , 2013, DOI: 10.1186/1472-6963-13-15
Abstract: Background Outcome quality indicators are rarely used to evaluate mental health services because most jurisdictions lack clinical data systems to construct indicators in a meaningful way across mental health providers. As a result, important information about the effectiveness of health services remains unknown. This study examined the feasibility of developing mental health quality indicators (MHQIs) using the Resident Assessment Instrument - Mental Health (RAI-MH), a clinical assessment system mandated for use in Ontario, Canada as well as many other jurisdictions internationally. Methods Retrospective analyses were performed on two datasets containing RAI-MH assessments for 1,056 patients from 7 facilities and 34,788 patients from 70 facilities in Ontario, Canada. The RAI-MH was completed by clinical staff of each facility at admission and follow-up, typically at discharge. The RAI-MH includes a breadth of information on symptoms, functioning, socio-demographics, and service utilization. Potential MHQIs were derived by examining the empirical patterns of improvement and incidence in depressive symptoms and cognitive performance across facilities in both sets of data. A prevalence indicator was also constructed to compare restraint use. Logistic regression was used to evaluate risk adjustment of MHQIs using patient case-mix index scores derived from the RAI-MH System for Classification of Inpatient Psychiatry. Results Subscales from the RAI-MH, the Depression Severity Index (DSI) and Cognitive Performance Scale (CPS), were found to have good reliability and strong convergent validity. Unadjusted rates of five MHQIs based on the DSI, CPS, and restraints showed substantial variation among facilities in both sets of data. For instance, there was a 29.3% difference between the first and third quartile facility rates of improvement in cognitive performance. The case-mix index score was significantly related to MHQIs for cognitive performance and restraints but had a relatively small impact on adjusted rates/prevalence. Conclusions The RAI-MH is a feasible assessment system for deriving MHQIs. Given the breadth of clinical content on the RAI-MH there is an opportunity to expand the number of MHQIs beyond indicators of depression, cognitive performance, and restraints. Further research is needed to improve risk adjustment of the MHQIs for their use in mental health services report card and benchmarking activities.

Abstract: Background The interRAI Suite contains comprehensive geriatric assessment tools designed for various healthcare settings. Although each instrument is developed for a particular population, together they form an integrated health evaluation system. The interRAI Acute Care Minimum Data Set (interRAI AC) is tailored for hospitalized older persons. Our aim in this study was to translate and adapt the interRAI AC to the Belgian hospital context, where it can be used together with the interRAI Home Care (HC) and the interRAI Long Term Care Facility (LTCF). Methods A systematic, comprehensive, and rigorous 10-step approach was used to adapt the interRAI AC to local requirements. After linguistic translation by an official translator, five researchers assessed the translation for appropriate hospital jargon. Three researchers double-checked for translation accuracy and proposed additional items. A provisional version was converted into the three official languages of Belgium—Flemish, French, and German. Next, a multidisciplinary panel of nine experts judged item relevance to the Belgian care context and advised which country-specific items should be added. After these suggestions were incorporated into the interRAI AC, hospital staff from nine Flemish hospitals field-tested the tool in their practice. After evaluating field-test results, we compared the interRAI AC with Belgian versions of the interRAI HC and interRAI LTCF. Next, the Flemish, French, and German versions of the Belgian interRAI portfolio were harmonized. Finally, we submitted the Belgian interRAI AC to the interRAI organization for ratification. Results Eighteen administrative items of the interRAI AC were adapted to the Belgian healthcare context (e.g., usual residence, formal community services prior to admission). Fourteen items assessing the ‘informal caregiver’, and 17 items, including country-specific items, were added (e.g., advanced directive for euthanasia). Conclusions The interRAI AC was adapted to local requirements using a meticulous and recursive 10-step approach. As use of the interRAI Suite continues to grow worldwide and as it continues to expand to other care settings and populations, this procedure can guide future translations. This procedure might also be used by others facing similar challenges of complex translation and adaptation situations, where multidimensional instruments are used across multiple care settings in multiple languages.
Towards a Physical Theory of Subjective Mental States  [PDF]
Sean Lee
Physics , 2007,
Abstract: Any complete theory of physical reality must allow for the ubiquitous phenomenon of subjective experience at some level, or risk being conceptually incoherent. However, as long as the ontological status of subjectivity itself remains unresolved, the topic will be seen as more within the purview of philosophy than of physics. Towards a resolution of this issue within empirically motivated physical theory, this article introduces an operational definition that ultilizes the general consensus that subjective mental states, whatever else is controversial about them, at least correlate in some way to physical states. It is shown here that implementing this underappreciated assumption within the framework of a physical theory in fact leads to wide-ranging consequences. In particular, a correlation requires there exist a well-defined mapping from a space of subjective mental states onto a space of information-bearing elements of some physical theory. Given the peculiar nature of subjective states as inherently private appearances, any empirical identification of states must be performed by the experiencing subject. It is argued that such an operationally defined 'self-measuring' act leads unavoidably to an 'uncertainty principle' that is analogous in some intriguing ways to Heisenberg's principle for quantum mechanics. A model is then introduced for subjective states as algorithmically incomputable numbers. Additionaally, an inequality similar to Bell's theorem may be derived, indicating an analogy with the violations of local reality and the ontology of observables within quantum mechanics.

Ethical issues in primary (health) care (PC) are common and are confronted daily. In the scarce literature that was available, Zoboli and Silva developed an instrument (IPE-APS) for perceiving ethical conflicts. Two empirical ex post facto studies to gather psychometric evidence for the instrument were outlined. In the first study, 88 nurses and physicians from Brazil’s Family Health (Saúde da Família—SF) responded to the IPE-APS, and the results confirmed its validity and accuracy. In total, 14 items were grouped in Factor I (relationship/responsibility), which was described as having human rights and deontological nature (Cronbach’s alpha = 0.92), and 11 items were grouped in Factor II, which was described as having a labor structure nature (Cronbach’s alpha = 0.90). In the second study, 207 SF professionals in Goiania, Goiás responded to the IPE-APS. The results showed that Factor I had a high factorial congruence index (0.98), which revealed high similarity and showed that the instrument displayed practical validity to identify and assess ethical problem perception in PC.

Abstract: The purpose of this study was to provide the evidence of psychometric evaluation on mathematics beliefs instrument (MBI) using Rasch model. 36 items of 5 point Likert scale with three constructs of mathematics beliefs towards nature, mathematics belief in teaching and mathematics beliefs in learning. 254 of secondary mathematics school teachers were selected to be the samples. The collected data were analysed using Winstep order to obtain the Rasch Model output. The findings revealed that the MBI has reliability value of 0.98 with separation index 6.27. The person reliability has value of 0.81 and the separation index of 2.08. Some misfits items were modified accordingly based on the fit statistics suggestions. The Rasch model output has provided statistical evidence for MBI for future purposes.

Abstract: ychometric properties of the Specific Thalassemia Quality of Life Instrument for adults Methodology (1336) Total Article Views Authors: Lyrakos GN, Vini D, Aslani H, Drosou-Servou M Published Date July 2012 Volume 2012:6 Pages 477 - 497 DOI: http://dx.doi.org/10.2147/PPA.S30763 Received: 11 February 2012 Accepted: 30 March 2012 Published: 02 July 2012 Georgios N Lyrakos,1,2 Demetra Vini,2 Helen Aslani,2 Marouso Drosou-Servou2 12nd Department of Anesthesiology, School of Medicine, University of Athens, Pain Clinic, Attikon University Hospital, 2Thalassemia Unit, General Hospital of Nikaia Ag. Panteleimon, Athens, Greece Background: No specific questionnaire has been developed to assess the health-related quality of life of thalassemia patients. Thus, the main objective of this study was to develop, according to psychometric standards, a self-administered Specific Thalassemia Quality of Life Instrument (STQOLI) for adult patients. Methods: First, a qualitative phase was conducted to generate items and identify domains using the critical analysis incident technique and a literature review. A list of easily comprehensible, non-redundant items was defined using the Delphi technique and a pilot study on ten thalassemia patients. This phase involved both patients and experts. The second step was a quantitative validation phase comprising a study of 128 thalassemia patients in a single hospital. It was designed to select items, identify dimensions, and measure reliability and internal and concurrent validity. The psychometric and scaling properties of the proposed 41-item Specific Thalassemia Quality of Life Instrument were then assessed among patients recruited from the Thalassemia Unit at the General Hospital of Nikaia, Greece. Results: The final questionnaire had 41 items comprising four main domains and one global item about general health. The factorial structure was satisfactory (loading > 0.40 on each factor of the four domains for all items). Interscale correlations ranged from 0.06 to 0.78, Cronbach's α-coefficients were 0.78 for the psychosocial domain, 0.77 for the chelation domain, 0.72 for the transfusion domain, 0.81 for the disease and symptoms domain, and 0.840 for the total score of the questionnaire. Conclusion: The 41-item Specific Thalassemia Quality of Life Instrument seems to be a valid tool for assessing health-related quality of life for patients with thalassemia. More research is needed to explore the universal properties of the questionnaire.

Psychology (PSYCH) , 2017, DOI: 10.4236/psych.2017.814157
Abstract: Objective: Traumatic stress can impact behaviours and neurological functioning of children and youth, with symptoms appearing similar to behaviours associated with psychiatric diagnoses (Siegfried et al., 2016). This study sought to examine the link between provisional diagnoses and trauma in a sample of children/youth receiving mental health services. Methods: A sample of 6649 children/youth (59% males) aged 4 - 18 years (Mage = 11.99, SD = 3.57) receiving services from 45 mental health agencies in Ontario were assessed using the interRAI Child and Youth Mental Health (ChYMH) instrument (Stewart et al., 2015a). We examined the interRAI Traumatic Life Events Collaborative Action Plan (CAP; Stewart et al., 2015b) and provisional diagnoses of attention-deficit/hyperactivity disorder (ADHD), anxiety disorders, reactive attachment disorder (RAD), mood disorders, substance-related disorders, and sleep disorders. Results: Compared to boys, girls were more likely to trigger the interRAI Traumatic Life Events CAP and to have a provisional diagnosis of anxiety, mood, and sleep disorders. Boys were more likely to have a provisional diagnosis of ADHD than girls. Multiple logistic regression analyses indicated that boys diagnosed with substance-related disorders had 1.79 higher odds of triggering the interRAI Traumatic Life Events CAP. ADHD, anxiety disorders, RAD, and mood disorders were also each significant predictors of potential traumatic stress regardless of sex. Conclusions/Implications: Findings suggest that several provisional diagnoses were significantly related to potential traumatic stress. Clinicians may find value in assessing for trauma, asking the question “What happened?” when confirming a psychiatric diagnosis in order to determine the best plan of care.
