Functioning in schizophrenia: a Delphi study covering the perspective of physiotherapists

Methodological considerations in cross-sectional studies validating the International Classification of Functioning, Disability and Health (ICF) Core-Sets: a systematic review

PURPOSE

To describe and analyze the methodological characteristics and quality of cross-sectional studies that have validated an ICF-CS.

MATERIALS AND METHODS

A systematic review was conducted to identify empirical studies published in English that validated any ICF-CS using a cross-sectional design. Databases searched included Web of Science, Scopus, CINAHL, PubMed, Embase, and PsycINFO. The search was conducted in November 2022 with an update in October 2023. Two independent reviewers coded studies that met the inclusion criteria and assessed their methodological quality and risk of bias using the AXIS tool. Synthesis was performed by calculating frequencies and percentages.

RESULTS

87 articles validating 24 ICF-CSs were analyzed. Most articles showed strengths in consistency between study objectives and the outcome variables measured. However, a large majority did not report sample size calculation (up to 94.2% in Delphi studies), and few validation studies were conducted in the WHO regions of Africa and the Eastern Mediterranean.

CONCLUSIONS

The quality of cross-sectional studies validating ICF-CSs was satisfactory, although several articles did not describe aspects such as sample size calculation. Validity evidence for ICF-CS studies could be improved by conducting more multicenter studies, replicating ICF-CS validation studies in different WHO regions, and through synthesis of existing research.

Validation of the Comprehensive and Brief International Classification of Functioning, Disability and Health Core Sets for Schizophrenia from the Perspective of Individuals Diagnosed with the Disorder: A Worldwide Study Using Focus Groups

The comprehensive and brief International Classification of Functioning, Disability and Health (ICF) core sets for schizophrenia, based on the World Health Organization (WHO) framework, aim to describe the functioning of individuals with schizophrenia. The objective of this study was to identify the most common problems faced by these individuals and validate the ICF core sets. Eight focus groups were conducted, recorded, and transcribed verbatim. The linking process involved two independent coders identifying meaningful units and linking agreed-upon concepts to the ICF categories. Data saturation was defined as the point at which no new categories emerged from additional focus groups. The 37 participants in this study represented the WHO regions of Africa, South-East Asia, the Western Pacific, and Europe. The focus groups confirmed the relevance of all ICF core set categories, with an additional 21 second-level categories being proposed in at least six of the eight focus groups. In this study, the ICF core sets for schizophrenia were validated from the perspective of individuals. However, several second-level categories not currently included in the ICF core sets also emerged. To ensure that the ICF core sets are truly international in scope, the potential relevance of these categories should be investigated further.

Validation of the international classification of functioning, disability, and health (ICF) core sets for musculoskeletal conditions in a primary health care setting from physiotherapists' perspective using the Delphi method

PURPOSE

To analyze the possibilities of using ICF core sets for musculoskeletal conditions in primary care physiotherapy units of the Health Service of "Castilla y León" (Spain).

METHODS

A three-round Delphi study was conducted by physiotherapists working in a primary care setting. The data obtained were linked to second-level ICF categories and their relevance was assessed by the participants. The most relevant categories were compared with those present in the existing ICF core sets for musculoskeletal conditions.

RESULTS

Eighty-four physiotherapists participated in the survey. The consensus was reached for 45 ICF categories and 5 personal factors after the survey. Thirty-five of these categories were present in the Comprehensive Core Set for post-acute Musculoskeletal Conditions. In addition, 35 categories present in the core set were not considered relevant from the participants' perspective.

CONCLUSIONS

Physiotherapists mainly considered movement-related categories as relevant. The ICF core set for post-acute musculoskeletal conditions comprises many of these categories and can therefore be taken as a basis for the adoption of ICF in the clinical context.

RELEVANCE

Primary care physiotherapists should be aware of the advantages of using ICF in their clinical settings.Implications for RehabilitationThis study shows which body functions and structures, activities and participation, environmental factors, and personal characteristics are relevant from primary care physiotherapists' perspective assessing persons with musculoskeletal conditions.The Comprehensive ICF Core Set for Subacute Musculoskeletal Conditions includes most of the categories identified in this study, but they need to be refined to fully represent the primary care physiotherapists' perspective.The results of this study support the use of the Comprehensive ICF Core Set for Subacute Musculoskeletal Conditions as a basis for operationalizing ICF in this clinical setting.

Network Analysis of the Brief ICF Core Set for Schizophrenia

Background

The International Classification of Functioning, Disability, and Health Core Sets (ICF-CSs) for schizophrenia are a set of categories for assessing functioning in persons with this health condition. This study aimed to: a) estimate the network structure of the Brief ICF-CS for schizophrenia, b) examine the community structure (categories strongly clustered together) underlying this network, and c) identify the most central categories within this network.

Methods

A total of 638 health professionals from different backgrounds and with a significant role in the treatment of individuals with schizophrenia participated in a series of Delphi studies. Based on their responses we used the Ising model to estimate the network structure of the 25-category Brief ICF-CS, and then estimated the degree of centrality for all categories. Finally, the community structure was detected using the walktrap algorithm.

Results

The resulting network revealed strong associations between individual categories within components of the ICF (i.e., Body functions, Activities and participation, and Environmental factors). The results also showed three distinct clusters of categories corresponding to the same three components. The categories e410 Individual attitudes of immediate family members, e450 Individual attitudes of health professionals, d910 Community life, and d175 Solving problems were among the most central categories in the Brief ICF-CS network.

Conclusion

These results demonstrate the utility of a network approach for estimating the structure of the ICF-CSs. Implications of these results for clinical interventions and development of new instruments are discussed.

Functioning Problems in Persons with Schizophrenia in the Russian Context

Assessing functionality in schizophrenia from a biopsychosocial perspective is essential to generate treatments that respond to the needs of the individual in his/her context. This research aims to assess the prevalence of functioning problems and their association with socio-demographic and clinical variables in a sample of Russian individuals with schizophrenia, using the International Classification of Functioning, Disability, and Health as a framework. An empirical cross-sectional study assessed the functioning of 40 individuals with schizophrenia using the International Classification of Functioning, Disability, and Health Core Set for schizophrenia. For the Body functions component, the highest prevalence of problems was found in b144 Memory functions (75%) and b140 Attention functions (70%). In the Activities and participation component, the greatest limitations were in d770 Intimate relationships (79.3%) and d240 Handling stress and other psychological demands (82.5%). In the Environmental factors, the most frequent problems were in e110 Products or substances for personal consumption (25%) and e460 Societal attitudes (22.5%); when scored as facilitators, the highest rated categories were e125 Products and technology for communication (100%) and e165 Assets (100%). These results may guide the design of specific treatments for these individuals and serve as a starting point for further studies in similar contexts and in other regions in Russia.

An Integrated Account of Expert Perspectives on Functioning in Schizophrenia

An integrated and interdisciplinary care system for individuals with schizophrenia is essential, which implies the need for a tool that assesses the difficulties and contextual factors of relevance to their functioning, and facilitates coordinated working across the different professions involved in their care. The International Classification of Functioning, Disability and Health Core Sets (ICF-CS) cover these requirements. This study aimed to evaluate the content validity of the ICF-CSs for schizophrenia from the perspective of experts. Six three-round Delphi studies were conducted with expert panels from different professional backgrounds which have played a significant role in the treatment of individuals with schizophrenia (psychiatry, psychology, nursing, occupational therapy, social work and physiotherapy). In total, 790 experts from 85 different countries participated in the first round. In total, 90 ICF categories and 28 Personal factors reached expert consensus (reached consensus from four or more professional perspectives). All the categories in the brief version of the ICF-CS for schizophrenia reached consensus from all the professional perspectives considered. As for the comprehensive version, 89.7% of its categories reached expert consensus. The results support the worldwide content validity of the ICF-CSs for schizophrenia from an expert perspective and underline the importance of assessing functioning by considering all the components implied.

Trust, conversations and the 'middle space': A qualitative exploration of the experiences of physiotherapists with clients with suicidal thoughts and behaviours

In Australia, physiotherapists are registered healthcare practitioners who possess the knowledge and skills to care for clients with poor physical health as a result of musculoskeletal, neurological, and respiratory conditions. Although physiotherapists are not considered a primary profession in the Australian mental health workforce, the association between suicide and poor physical health suggests that they may encounter clients with suicidal thoughts and behaviours. We used a qualitative approach inspired by phenomenology to explore the experiences of nine physiotherapists who encountered clients with suicidal thoughts and behaviours. We used a combination of focus groups and in-depth interviews to collect this data. The data were analysed inductively using framework analysis. The main themes identified in the data were: i) the importance of trust, ii) the mechanism of conversation, and iii) the 'middle space'. The middle space refers to the experience of working with clients at risk of low or medium risk of suicide. A trusting practitioner-client relationship was reported to be essential in facilitating the disclosure of suicidal thoughts and behaviours. Physiotherapists also reported that less structured subjective assessments encourage clients to talk more openly, which in turn facilitates the disclosure of suicidal thoughts and behaviours. Once the disclosure of suicidal thoughts and behaviours occurred, physiotherapists reported a lack of confidence regarding role clarity and issues associated with this. Difficulties were most evident during encounters with clients with low to medium suicide risk due to a lack of confidence in the accuracy of assessment of these clients. The findings suggest that physiotherapists are well placed to detect and/or receive disclosure of suicidal thoughts and behaviours, as well as the need for physiotherapists to be trained in how to support clients who disclose suicidal thoughts and behaviours.
