Psychometric Evaluation of the Toileting Behaviors: Women's Elimination Behaviors Scale in a Sample of College Women

Avaliação da função dos músculos do assoalho pélvico e incontinência urinária em universitárias: um estudo transversal

RESUMO O objetivo deste estudo foi avaliar a função e pressão de contração dos Músculos do Assoalho Pélvico (MAP) e a prevalência de Incontinência Urinária (IU) em universitárias. Realizou-se um estudo transversal, com universitárias entre 18 e 35 anos, nulíparas, que já tiveram relação sexual e que nunca realizaram tratamento fisioterapêutico para Disfunções dos Músculos do Assoalho Pélvico (DMAP). Todas as voluntárias realizaram a anamnese, responderam aos questionários international consultation on incontinence questionnaire - Short Form (ICIQ-SF) e incontinence severity index questionaire (ISI-Q), e realizaram avaliação da função e manometria dos MAP. Foi utilizado o teste de Shapiro-Wilk e os valores da amostra são expressos em medianas, intervalos interquartílicos, frequências absolutas e relativas. Foram avaliadas 35 mulheres, das quais 65,72% apresentaram tônus normal, mas apenas 5,71% realizavam a contração adequada dos MAP, com medianas baixas para todas as etapas do PERFECT e na manometria dos MAP. A prevalência de IU foi 57,14%, sendo a Incontinência Urinária de Urgência (IUU) a queixa mais prevalente (50%) e com severidade moderada (55%). Este estudo permitiu identificar déficit na função dos MAP e altos índices de IU em universitárias, demostrando a importância de conscientizar esse público sobre essa DMAP.

Toileting Behaviors Related to Urination in Women: A Scoping Review

This scoping review explores the state of science regarding women’s toileting behaviors, gaps in knowledge, and areas for future research. Online databases were searched to identify papers published in English between January 2010 through July 2019; the search identified 25 articles. The Toileting Behaviors–Women’s Elimination Behaviors scale has been published in four validated language versions and used in 17 of the 25 studies. The most frequent behaviors include concern about public toilet cleanliness, delaying urination when busy or away from home, and using different toileting postures at and away from home. Determinants of toileting behaviors include environmental factors, chronic health conditions, and cognitive/psychological factors. Associations were found between toileting behaviors and lower urinary tract symptoms and between toileting postures and uroflowmetric parameters and post-void residual volume. Strategies that address modifiable determinants of toileting behaviors should be developed and tested in future research. Furthermore, little is known about the toileting behaviors and bladder health in older women and women from developing countries. Rigorous studies are needed to better understand the underlying mechanisms of toileting behaviors, the nature of associations between toileting behaviors and lower urinary tract symptoms, and effects of the environment on women’s toileting behaviors.

Toileting behaviors and factors associated with urinary incontinence in college-aged female students in China

INTRODUCTION AND HYPOTHESIS

Urinary incontinence (UI) is prevalent among women, including young women (18-30 years old). This article aims to explore the prevalence of UI, as well as toileting behaviors and other factors that are associated with UI, in female college students in central China.

METHODS

We used convenience sampling to recruit 1000 students from five institutions of higher education. We distributed pencil-and-paper questionnaires to obtain demographic, environmental, and general health information, including whether UI was present or not, and information regarding toileting behaviors used by the respondents.

RESULTS

Most students, n = 929, responded to the questionnaire. Their ages ranged from 18 to 26 years old (average: 20.5 ± 1.6); 23.6% of these respondents reported UI, 52.7% often/always worried about public toilet cleanliness, and 25.3% often/always delayed emptying their bladder when they were busy. Respondents who were between 21 and 26 years old had a lower probability of UI (odds ratio [OR] = 0.867 and 95% confidence interval [CI] = 0.771-0.975) than younger respondents (18-21 years old). Respondents who reported constipation (OR = 2.395, 95% CI = 1.494-3.839), drank alcohol (OR = 1.763, 95% CI = 1.114-2.792), often/always delayed urination (OR = 1.738, 95% CI = 1.306-2.313), and/or often/always strained to urinate (OR = 1.433, 95% CI = 1.111-1.849) had greater odds of having UI than respondents who did not have constipation or engage in these behaviors.

CONCLUSIONS

UI is prevalent in young Chinese women who are attending college. These women should be asked and given culturally appropriate information about UI and associated factors that include toileting behaviors.

Validity and Reliability of the Korean Version of the Women's Toileting Behavior Scale

PURPOSE

The purpose of this study was to investigate the validity and reliability of the Korean version of the Toileting Behavior Scale (KTBS) to assess women's toileting behavior related to urinary elimination.

METHODS

The original English version, the Toileting Behavior: Women's Elimination Behaviors scale, was translated into Korean with forward and backward translation. Examinations of internal consistency reliability, construct validity using exploratory factor analysis and confirmatory factor analysis, item convergent validity, and discriminant validity were conducted with SPSS/WIN 23.0 and AMOS/WIN 23.0 software. Concurrent validity was examined with the International Consultation on Incontinence Questionnaire-Short Form.

RESULTS

Cronbach α for the overall scale was 0.78, and the 5 subscales ranged from 0.79 to 0.94. The exploratory factor analysis revealed 5 factors for the 17-item scale. Confirmatory factor analysis supported good convergent and discriminant values (λ=0.49-0.96, critical ratio=4.51-15.68>1.97, P<0.05, construct reliability=0.72-0.97). The concurrent validity was supported by correlation with the International Consultation on Incontinence Questionnaire-Short Form (r=0.146, P=0.011).

CONCLUSION

The KTBS (17 items) is an appropriate tool to measure older Korean women's toileting behavior with good validity and reliability.
