Vulnerability to physical inactivity: content validation of markers for adults

Abstract

Objective

To validate the content of markers of vulnerability to physical inactivity in adults.

Methods

This is a methodological study, based on psychometrics, which aims to develop constitutive and operational definitions of markers of vulnerability to physical inactivity in adults and content validation by experts. Data were analyzed by calculating Content Validity Index (CVI) and binomial test.

Results

Thirteen judges, health professionals, researchers with publications on the subject, from seven Brazilian states (Ceará, Pernambuco, Piauí, Bahia, Amazonas, Santa Catarina and Rio de Janeiro), participated in the validation. A total of 40 markers were validated, with 40 constitutive definitions and 133 operational definitions. These were grouped into two interrelated dimensions (subject and social) and 12 subdimensions (physical situation, psycho-emotional situation, behavior, functional literacy, interpersonal relationships, sociodemographic profile, environment, policies, institutional context, culture, fundamental rights). All had excellent CVI (≥ 0.78).

Conclusion

The proposed markers presented adequate parameters of validity and can be used to operationalize the measurement of vulnerability to physical inactivity phenomenon in the construction of instruments and strategies for patient care and coping with physical inactivity.

Introduction

Vulnerability is a construct that can be observed from different perspectives. One of the most advocated approaches reveals the dynamic way that cultural and social elements connect to individuals, to create and materialize conditions that increase the possibility of threats and dangers.(11. Oviedo RA, Czeresnia D. O conceito de vulnerabilidade e seu caráter biossocial. Interface Comun Saúde Educ. 2015;19(53):237-50.) Its applications in the health area cover multiple themes at different levels of entanglement and complex health processes.(22. Clark B, Preto N. Exploring the concept of vulnerability in health care. CMAJ. 2018;190(11):E308-E9. .,33. Florêncio RS, Moreira TM, Pessoa VL, Cestari VR, Silva VM, Rabelo SM, et al. Mapeamento dos estudos sobre vulnerabilidade em saúde: uma revisão de escopo. Res Society Development. 2020;9(10):e2079108393.)

Vulnerability in health is understood as a human condition that involves interaction between elements of a given health phenomenon, from the individual and sociopolitical perspective.(44. Enang I, Murray J, Dougall N, Wooff A, Heyman I, Aston E. Defining and assessing vulnerability within law enforcement and public health organisations: a scoping review.

Several perspectives emerge, such as vulnerability to stress,(77. Matos RL, Araújo MR. Vulnerabilidade ao estresse e estratégias de enfrentamento: um estudo comparativo no ambiente hospitalar. Rev Psicol Saúde. 2021;13(2):65-81.,88. Allen L, Dwivedi Y. Micro-RNA mediators of early life stress vulnerability to depression and suicidal behavior. Mol Psychiatry. 2020;25(2):308–20.

Cogitare Enferm. 2021;26:e74976.) among others. In this understanding, elements such as socioeconomic status, demographic status, health behaviors, clinical profile, health services, social support, health status, emotional aspects, bonds, beliefs, perceptions, exposure and susceptibility are considered.

One of the important elements of health for the healthy development of people and populations is physical activity.(1515. Salvo D, Garcia L, Reis RS, Stankov I, Goel R, Schipperijn J, et al. Physical activity promotion and the united nations sustainable development goals: building synergies to maximize impact. J Phys Act Health. 2021;18(10):1163-80.) However, despite the evidence on the harm caused by physical inactivity, the frequency of people who are able to practice physical activity in sufficient quantity, intensity and duration to enjoy the protective effects of diseases and promote health is still low.(1616. Bezerra MA, Sousa JS, Simões Neto JC, Gomes Filho AS, Bottcher LB. Prevalência de inatividade física na adolescência: revisão sistemática. Health Humans. 2020;2(1):1-9. Review.

-1818. Varela AR, Pratt M, Kohn ER, Hallal PC. O observatório global de atividade física: um panorama sobre duas pandemias. Rev Bras Ativ Física Saúde. 2021;26:e0205.)It is recognized that social inequalities influence adherence to physical activities, and put some population groups at a notable disadvantage.(1919. Knuth AG, Antunes PC. Práticas corporais/atividades físicas demarcadas como privilégio e não escolha: análise à luz das desigualdades brasileiras. Saúde Soc. 2021;30:e200363.) Such inequalities associated with personal aspects and their intersubjective relationships can increase the chances of physical inactivity at an individual and collective level.(2020. Palma A, Salomão LC, Nicolodi AG, Caldas A. Reflexões acerca da adesão aos exercícios físicos: comportamento de risco ou vulnerabilidade? Rev Movim Educ Física. 2003;9(3):83-100.)

Situations in which individual choice is difficult show weakening conditions and reactive impossibility, which affects the level of vulnerability.(1919. Knuth AG, Antunes PC. Práticas corporais/atividades físicas demarcadas como privilégio e não escolha: análise à luz das desigualdades brasileiras. Saúde Soc. 2021;30:e200363.,2020. Palma A, Salomão LC, Nicolodi AG, Caldas A. Reflexões acerca da adesão aos exercícios físicos: comportamento de risco ou vulnerabilidade? Rev Movim Educ Física. 2003;9(3):83-100.) These conditions of vulnerability of subjects and social need to be considered for the effective planning and development of strategies to face physical inactivity.

Thus, in order to understand how much personal aspects and the social context in which one is inserted favor or hinder physical activity, an analysis from the perspective of vulnerability is suggested. Thus, it is understood that the subject-social dimension elements interact, producing conditions of precariousness, which have repercussions on the adoption or not of behavior, i.e., physical inactivity is understood beyond the result of individuals’ will. Such understanding problematizes the repercussion of health inequities and highlights the relevance of structural changes in different segments, such as environment, politics, culture, economy, and others.

Several aspects exacerbate vulnerability to physical inactivity, and because it is a latent trait, it is not directly observable, being represented by observable objective elements, which allow its measurement, the so-called attributes. Knowing the dimensionality and the constitutive and operational elements of this latent trait enables the construction of questionnaires that cover the different elements that make up this construct, which allows for better monitoring and surveillance of vulnerability to physical inactivity in populations, as well as supporting strategies that promote physical activity and health in the most different contexts. However, to our knowledge, there are no instruments that measure the vulnerability to physical inactivity construct for the Brazilian adult population.

Considering the above, the present study aims to validate the content of markers of vulnerability to physical inactivity in adults.

Methods

This is a methodological study, based on psychometrics, which establishes specific procedures for the elaboration and validation of instruments(2121. Pasquali L. Instrumentação psicológica-fundamentos e práticas. Porto Alegre: Artmed; 2010. 568 p.) anchored in three poles (theoretical, empirical and analytical). The construction of this article refers to the theoretical pole, divided into phases: 1) investigation of the vulnerability to physical inactivity construct, its dimensionality, constitutive and operational elements; 2) mapping of markers of vulnerability to physical inactivity; 3) construction of constitutive and operational definitions of these markers; and 4) content validation of markers by experts. The fulfillment of the first three phases was based on the literature, with critical reflection and via scoping review.

In light of the theoretical contribution(11. Oviedo RA, Czeresnia D. O conceito de vulnerabilidade e seu caráter biossocial. Interface Comun Saúde Educ. 2015;19(53):237-50.,55. Florêncio R, Moreira T. Health vulnerability model: conceptual clarifi cation. Acta Paul Enferm. 2021;34:eAPE00353.,2222. Ayres JR, Calazans GJ, Saletti Filho HC, França-Junior I. Risco, vulnerabilidade e práticas de prevenção e promoção da saúde. In: Campos GW, Minayo MC, Akerman M, Drumond Júnior M, Carvalho Y M, organizadores. Tratado de saúde coletiva. 2ed. 2012. p. 375-417.) on vulnerability in health, the construct addressed in this study was defined. Thus, vulnerability to physical inactivity is understood as a condition of human life produced in the interaction between elements of multiple dynamic relationships of subjects in their social context, which generate greater precariousness and exposure to factors that are unfavorable to physical activity for health, such as its damage and the unavailability of means of coping.

To help investigate its dimensionality and constitutive and operational elements, as well as its markers, a scoping review was carried out based on specific guidelines for this type of study.(2323. Peters MD, Godfrey C, McInerney P, Munn Z, Tricco AC, Khalil H. Chapter 11: Scoping Reviews (2020 version). In: Aromataris E, Munn Z, editors. JBI Manual for Evidence Synthesis.

The search for articles was carried out in five stages: guiding question identification; eligibility criteria establishment; information source definition; search and selection strategy development; analysis and synthesis of results. Further details on the method are available in the protocol registered in the Open Science Framework (DOI 10.17605/OSF.IO/KSA98).

To identify the elements that made up the vulnerability to physical inactivity construct in adults, considering the terminological and operational limits and possibilities of an innovative aspect of what is intended to be investigated, the following question was formulated: What are the predictors and determinants of physical inactivity in adults? The Population, Concept, Context (PCC) strategy adopted weaves: P (adults), C (predictors and/or determinants of physical activity/physical inactivity), C (physical activity/physical inactivity); and two search strategies were built using three controlled health vocabularies (MESH, DECS and EMTREE), together with natural language, to ensure greater sensitivity and expansion of search results (Appendix 1 Appendix 1 Search strategy 1.

Grey literature strategies Google Academic and Open Grey (“predictors of physical inactivity” OR “determinants of physical inactivity” OR “predictors of physical activity” OR “determinants of physical activity”) AND adults BDTD (preditor OR determinante) AND (“inatividade física” OR “atividade física”) ).

Original, observational or experimental studies, without language delimitation or publication year limit, published in journals, dissertations and theses defended, found in primary and secondary sources and gray literature were included: SPORTDiscus; Web of Science (WoS); National Library of Medicine (MEDLINE) via EBSCO; Scopus by Elsevier; Latin American and Caribbean Literature on Health Sciences (LILACS) via Virtual Health Library (VHL); BASE; Cochrane Library; Cumulative Index to Nursing and Allied Health Literature (CINAHL); Digital Library of Theses and Dissertations (BDTD), Google Scholar; and Open Gray.

Study selection was blinded and paired at all stages by two researchers and disagreements were resolved by consensus and with the participation of a third evaluator. An analysis of duplicate titles was performed initially, then, to exclude studies that did not meet the eligibility criteria, titles and abstracts were read, followed by reading the studies in full.

After selecting the studies, data were extracted: Population (number of participants, age, sex, characteristic and country of origin), Concept (predictors/determinants of physical inactivity and categories of analysis), Context (approach and form of assessment of physical activity/physical inactivity, instrument used) and Design (type of study). It is noteworthy that, in these studies, the statistically significant variables associated with physical inactivity were extracted and that some data were interpreted to standardize terms and eliminate residual confusion. The main findings resulting from the studies were distributed and classified according to the conceptual model of Vulnerability in Health proposed by Florêncio and Moreira(55. Florêncio R, Moreira T. Health vulnerability model: conceptual clarifi cation. Acta Paul Enferm. 2021;34:eAPE00353.). Thus, the findings were analyzed from the perspective of vulnerability, and adjustments were made to identify potential markers to operationalize the latent trait studied. All adjustments were based on a reflexive-interpretative process in order to favor the construction of constitutive and operational definitions of the construct.

The constitutive (concepts and definitions, established from abstract realities) and operational (concrete operations or physical behaviors) definitions(2121. Pasquali L. Instrumentação psicológica-fundamentos e práticas. Porto Alegre: Artmed; 2010. 568 p.) were built from analyzed articles and the conceptual model adopted, considering the predefined psychometric criteria, in an attempt to deliberate the behaviors and attitudes by which the construct is expressed.

The fourth phase comprised content validation of dimensionality and markers with experts. The choice of experts considered academic training, scientific production, knowledge of methodological studies and professional performance, which took place through consultation on the Plataforma Lattes (a platform where you find professionals’ resumes) and the national database of the Coordination for the Improvement of Higher Education Personnel (CAPES - Coordenação de Aperfeiçoamento de Pessoal de Nível Superior). Experts were contacted by e-mail and invited to participate in the study, and they could also indicate other professionals with the same profile. After acceptance, the Informed Consent Term (ICF), an instrument developed by the author and instructions for completion were sent.

Considering Pasquali’s suggestions,(2525. Pasquali L. Psicometria: teoria dos testes na psicologia e na educação. Rio de Janeiro: Vozes; 2017. 392 p.)regarding the number of 06 to 20 participants, 25 experts were invited. The experts had 15 to 20 days to judge the relevance and pertinence of dimensions, subdimensions, constitutive and operational definitions of markers, in relation to the studied construct. To this end, a four-point ordinal scale was used: 1) non-indicative; 2) little indicative; 3) indicative; 4) very indicative.

Pasquali(2121. Pasquali L. Instrumentação psicológica-fundamentos e práticas. Porto Alegre: Artmed; 2010. 568 p.) recommends a minimum agreement of 80% among judges. Furthermore, cultural aspects and the relativity of content validity were also considered, according to Cohen, Swerdlik and Sturman.(2626. Cohen RJ, Swerdlik ME, Sturman ED. Testagem e avaliação psicológica: introdução a testes e medidas. México: AMGH Editora; 2014. 756 p.)

After experts’ analysis, Content Validity Index (CVI) was calculated with the number of responses 3 and 4 divided by the total number of responses.(2727. Polit DF, Beck CT. Fundamentos de pesquisa em enfermagem: avaliação de evidências para a prática da enfermagem. 7ed. Porto Alegre: Artmed; 2011. 670 p.) Those that received a score of 1 or 2 were revised or eliminated. The operational definitions were assessed individually, and then the average score of each marker and subdimension was calculated.

The CVI of items > 0.78 and average total CVI of > 0.90 were considered excellent. The variables were categorized to perform the exact test of binomial distribution for small samples, considering a significance level of 5% and a proportion of 0.80 of agreement to estimate CVI statistical reliability.

This study was approved by the Ethics Committee of the Universidade Estadual do Ceará, under Opinion 4,534,477/2021 and CAAE (Certificado de Apresentação para Apreciação Ética - Certificate of Presentation for Ethical Consideration) 37754720.4.0000.5534, and was carried out according to Resolution 466/2012 of the Brazilian National Health Council (Conselho Nacional de Saúde).(2828.

Results

Of the 1,397 studies initially identified, after removing the duplicates, reading the titles and abstracts and reading in full, 89 studies resulted, with distinct populations over a wide geographic range. The detailed description of such studies and results will be available in a specific publication linked to the same protocol registered in the Open Science Framework.

Initially, 22 markers emerged, grouped within the dimensions and subdimensions of the health vulnerability model. Some elements of such dimensions were not included in the articles, as the included studies did not investigate certain variables. Some markers found drove the addition of new elements to the model. After elucidating the dimensions, subdimensions and markers, the constitutive and operational definitions were elaborated. The theoretical model of vulnerability to initial physical inactivity had 02 dimensions, 13 subdimensions, 42 markers and 152 operational definitions.

Soon after, the content validation of these elements began. Of the 25 experts invited, 20 accepted to participate in the study and 13 responded to the instrument within the requested time. Thus, content analysis was carried out by 13 experts, health professionals with proven professional performance, researchers with publications on the subject, including physical education professionals and nurses, from seven Brazilian states (Ceará, Pernambuco, Piauí, Bahia, Amazonas, Santa Catarina and Rio de Janeiro).

As for dimensionality, some suggestions were analyzed and met, such as the recommendation to replace terms and expressions. As for markers, the main suggestions indicated that the initial markers health-disease situation, physical and functional limitation, and nutritional status should be grouped into a single marker that expressed individuals’ general health status. The grouping of mental health and self-esteem markers was also suggested, with the replacement of the term for a marker that represented the psychological state and also the relocation of interpersonal violence and discrimination in the interpersonal relationships subdimension. It was then suggested the inclusion of sex, ethnicity and cultural formation markers. As CVI was < 0.80, three markers were excluded (marital status, cultural connection and cultural differences), in addition to 03 constitutive definitions and 19 operational definitions.

After making the changes, according to Table 1, the subject dimension encompassed 20 markers in four subdimensions. Dimensions and markers with CVI > 0.80 remained in the model.

Table 2 presents the social dimension, which encompassed 20 markers in eight subdimensions. Dimensions and markers with CVI > 0.80 remained in the model. The subject and social dimensions were validated with CVI 0.98.

Discussion

In the different fields of knowledge and in the different applications in life sciences, vulnerability is a notion in permanent construction. In this way, the polysemy of its concept is a challenge that encourages dialogue and the conception of new conceptual ramifications to assist in the understanding of the complex health-disease-care process of populations.(2929. Ayres J. Vulnerabilidade, direitos humanos e cuidado: aportes conceituais. In: Barros S, Campos PF, Fernandes JJ. Atenção à saúde de populações vulneráveis. Barueri: Manole; 2014. pp. 1-25.,3030. Dimenstein M, Cirilo Neto M. Abordagens conceituais da vulnerabilidade no âmbito da saúde e assistência social. Rev Pesq Práticas Psicossociais. 2020;15(1):1-17.) In general, the concept of vulnerability is related to greater or lesser availability of resources, possibilities of choices, social justice and other factors of an individual, collective and contextual nature.(2222. Ayres JR, Calazans GJ, Saletti Filho HC, França-Junior I. Risco, vulnerabilidade e práticas de prevenção e promoção da saúde. In: Campos GW, Minayo MC, Akerman M, Drumond Júnior M, Carvalho Y M, organizadores. Tratado de saúde coletiva. 2ed. 2012. p. 375-417., 3131. Nichiata LY, Bertolozzi MR, Takahashi RF, Fracolli LA. The use of the “vulnerability” concept in the nursing area. Rev Lat Am Enfermagem. 2008;16(5):923-8.)

In the context of physical inactivity, vulnerability analysis makes it possible to broaden the understanding of the phenomenon as a result of the intertwining of subjects’ behavior and experiences with their subjectivities, social, cultural and political conditions allied to actions that promote physical activity for health. Thus, physical activity interventions can be more effective and comprehensive, by strengthening the positive influences of the various components of the dimensions and subdimensions of vulnerability to physical inactivity.

This is a conceptual model, which considers the determinants of physical activity, but is not restricted to probabilities, by proposing the perspective of a conceptual basis that analyzes the interaction between the dimensions involved, pointing out indicators of weaknesses, health inequities and inequalities social,(2222. Ayres JR, Calazans GJ, Saletti Filho HC, França-Junior I. Risco, vulnerabilidade e práticas de prevenção e promoção da saúde. In: Campos GW, Minayo MC, Akerman M, Drumond Júnior M, Carvalho Y M, organizadores. Tratado de saúde coletiva. 2ed. 2012. p. 375-417.) providing, in addition to indicators of interventions, a programmatic framework for militancy related to the promotion of physical activity for the population’s health.

Studying health issues from the perspective of vulnerability involves the search for a way to better understand and understand the health-disease process.(66. Padoveze MC, Juskevicius LF, Santos TR, Nichiata LI, Ciosak SI, Bertolozzi MR. The concept of vulnerability applied to Healthcare-associated Infections. Rev Bras Enfermagem. 2019;72:299-303.,1010. Cestari VR, Florêncio RS, Pessoa VL, Moreira TM. Validação dos marcadores da vulnerabilidade em saúde da pessoa com insuficiência cardíaca. Rev Eletr Acervo Saúde. 2021;13(5):e7282.) Analyzing physical inactivity and its aggravations from the dimension of vulnerability makes it possible to analyze social inequalities, which place certain population groups at a disadvantage in terms of chances of having an active lifestyle, because, ddeprived of resources to guide a genuine choice, subjects are not always to blame for their physical inactivity.(1919. Knuth AG, Antunes PC. Práticas corporais/atividades físicas demarcadas como privilégio e não escolha: análise à luz das desigualdades brasileiras. Saúde Soc. 2021;30:e200363.)

The pandemic situation that is currently plaguing the world has emphasized how much the social inequality of populations has an impact on limiting the possibilities of practicing physical activities. Most people who continued to practice physical activity during leisure time had more opportunities and had a higher level of education. In this way, we propose the discussion of sociocultural aspects and a humanized and attentive look at social inequalities to promote equal physical activities.(3232. Crochemore-Silva I, Knuth AG, Wendt A, Nunes BP, Hallal PC, Santos LP, et al. Physical activity during the COVID-19 pandemic: a population-based cross-sectional study in a city of South Brazil. Cien Saude Colet. 2020;25(11):4249-58.)

The elucidation of markers of vulnerability to physical inactivity and their definitions were based on knowledge from the compilation of national and international studies, which investigated the phenomenon of physical inactivity in adults from several countries, in the light of a two-dimensional conceptual model, developed from conceptual clarification, similarity analysis and critical reflection on the ideas of Michel Foucault and Judith Butler on the social-subject.(55. Florêncio R, Moreira T. Health vulnerability model: conceptual clarifi cation. Acta Paul Enferm. 2021;34:eAPE00353.) These definitions were complemented by the knowledge of expert researchers, working in different regions of Brazil, who generated evidence of content validity, to enable a representative instrument of the latent trait, with comprehensive aspects and language, and considering the Brazilian cultural diversity. We chose to use the term markers with the possibility of denoting a fixed condition, but also situational and subject to transformation.

The validation process is relevant, as it is an estimate (judgment) as to the congruence between the latent trait and its physical representation. It refers to a measure based on the assessment of topics, subjects and content covered in the items, in the case of instrument construction.(2626. Cohen RJ, Swerdlik ME, Sturman ED. Testagem e avaliação psicológica: introdução a testes e medidas. México: AMGH Editora; 2014. 756 p.)

The results from the validation of the constitutive and operational definitions of the essential elements of vulnerability to physical inactivity showed satisfactory and reliable CVI. It is noteworthy that such elements are dynamic and interrelated, which allows the production of new configurations and incorporation of new elements, evidencing the power relations identified in subjects’ vulnerability and in social vulnerability.

The findings of this study can helpto better understand and apply the nursing diagnosis Sedentary lifestyle, included in NANDA – international in 2004,(3333. NANDA 21enfermagem e Diagnósticos 2021-2023. 12 ed. Porto Alegre: Artmed; 2021. 592 p.) with possibilities for improvement, review and accurate identification of its indicators and nomenclatures,(3434. Moreira RP, Guedes NG, Lopes MV, Cavalcante TF, Araújo TL. Diagnóstico de enfermagem estilo de vida sedentário: validação por especialistas. Texto Contexto Enferm. 2014;23:547-54.) for better diagnostic accuracy and development of strategies for patient care and promotion of physical activity for health. Moreover, in light of the International Classification for Nursing Practice (ICNP®),(3535. Carvalho CM, Cubas MR, Nóbrega MM. Brazilian method for the development terminological subsets of ICNP®: limits and potentialities. Rev Bras Enferm. 2017;70(2):430-5.) it can contribute to the elaboration of other statements of nursing diagnoses and interventions that seek to develop care based on scientific knowledge and according to patients’ needs, with the practice of regular physical activities being one of these needs.

It is known that several terms related to exercise are linked to different ICNP axes, such as adherence to exercise regime (diagnoses/outcomes), non adherence to exercise regime (diagnoses/outcpmes), lack of knowledge about exercise (diagnoses/outcomes), exercise promoting (interventions), etc. However, specific terms of physical activity/physical inactivity still need to be worked out. In addition to this theoretical contribution to the new construction evidenced here, nurses can identify existing terms that are close to what has been validated and build terminological subsets within the perspective of vulnerability.

This study has limitations, such as the restriction of the results to the theoretical aspect, without details about the construction and validation of items that can constitute an instrument for measuring vulnerability to physical inactivity. However, the elucidation of its dimensionality and its constitutive elements provides a substantial theoretical framework to enable the construction of questionnaires that analyze the phenomenon.

Therefore, further studies are suggested to expand the understanding of the phenomenon of physical inactivity in a broader perspective, as well as research oriented towards the development and validation of instruments for its assessment.

Conclusion

The proposed markers presented adequate parameters of validity and can be used to operationalize the measurement of the vulnerability to physical inactivity phenomenon and support the construction of assessment instruments for the diagnosis of the population, the development of care strategies and the confrontation of physical inactivity. Understanding physical inactivity based on vulnerability allows a reading of reality in its diversity and specificity, thus a condition is conceived that manifests itself in different ways in subjects’ vulnerability and in social vulnerability, and coping with it requires inter and multidisciplinary interventions as well as inter and multisectoral.
