## Abstract

Introduction. SATIS-Stroke was developed to measure satisfaction regarding activities and participation among stroke survivors based on the concepts contained in the International Classification of Functioning, Disability, and Health. However, this measure is only available in English and French.Objective. Perform the translation and cross-cultural adaptation of SATIS-Stroke to Brazilian Portuguese and test the preliminary reliability of this measure.Methods. The translation process followed standardized guidelines and consisted of six phases: initial translation, back-translation, analysis of expert committee, test of final version, submission, and assessment of all written reports. To test the preliminary test-retest reliability, the measure was administered by a single observer on two occasions with an interval of 7 to 14 days for the determination of intraobserver agreement and administered again by a second observer for the determination of interobserver agreement. Reliability was analyzed using the intraclass correlation coefficient (ICC2,1) and respective 95% confidence intervals (CI).Results. All stages of the cross-cultural adaptation process were respected and the final translated version of SATIS-Stroke exhibited semantic, idiomatic, cultural, and conceptual equivalence to the original version. The preliminary analysis revealed excellent intraobserver and interobserver reliability (ICC = 0.93; 95% CI: 0.83-0.97, p = 0.001 and ICC = 0.90; 95% CI: 0.74-0.96; p = 0.001, respectively). The items demonstrated adequate internal consistency, although ceiling and floor effects were considered beyond acceptable standards for some items. In the exploratory factor analysis, three factors were extracted that aggregated more than one construct to each component, but all were related to the “Activities and Participation” component of the International Classification of Functioning, Disability, and Health.Conclusion. The final version of the SATIS-Stroke scale in Brazilian Portuguese proved to be adequate and reliable for use on the Brazilian population. Further studies are underway to give continuity to the validation process and analyze the others measurement properties of the scale in the Brazilian population.

## Body

## 1. Introduction

According to the World Health Organization, stroke is the second major cause of death in the world and the third major cause of functional disability in worldwide [1]. With regard functioning, stroke survivors in Brazil demonstrate a moderate decline in participation and functional capacity [2]. After a stroke, the affected individual may have motor, sensory, perceptive, and cognitive impairments that exert an impact on functioning and lead to disability, with 24 to 75% of stroke survivors dependent on others for assistance with regard to activities of daily living [3–5]. These functional difficulties directly interfere with activities and social participation [6].According to the International Classification of Functioning, Disability, and Health (ICF), participation is defined as involvement in real-life situations in society, whereas activity is defined as the capacity to perform the actions and tasks of daily living [7, 8]. Both constructs are considered important measures in the rehabilitation process, since activities and participation enable an individual to establish social relations, develop skills to meet social needs, and perform routine tasks and find purpose and meaning in life, which can have a positive impact on both physical and mental health [9, 10]. The decline in activity and social participation following a stroke has been demonstrated in the Brazilian population [2] and there is a need to monitor these constructs during the rehabilitation process.Although the domains of the “Activities and Participation” component are presented in a single code list of the ICF, in clinical practice and for scientific purposes, these measures should be analyzed separately. For the classification and qualification of activities, it is necessary to use assessment tools that evaluate performance and functional capacity. However, such tests require adequate space to perform as well a previous training and a long application period [11, 12]. Among the measures available for the evaluation of social participation in the Brazilian population, such as the Assessment of Life Habits and the Stroke Specific Quality of Life scales, none addresses all domains of the ICF “Activities and Participation” component [13, 14]. Thus, there is a need for an assessment tool that is capable of measuring the activity and participation constructs in a single evaluation and that considers all ICF domains.SATIS-Stroke was developed to measure satisfaction regarding activities and participation following a stroke and is considered to be a complete scale for this purpose [8, 12, 15]. However, this measure was originally published in French and, to date, has only been translated into English, with no version adapted to the Brazilian population. Therefore, the aim of the present study was to perform the translation and cross-cultural adaptation of SATIS-Stroke to Brazilian Portuguese, test its preliminary reliability and internal validity, and perform factor analysis using different samples of stroke survivors. The results obtained in this study are expected to contribute to the enhancement of the rehabilitation process for stroke survivors and facilitate the evaluation of functioning as recommended by the World Health Organization [9, 12].


## 2. Methods

### 2.1. Study Design and Ethical Aspects

A methodological, cross-sectional study was conducted involving the translation and cross-cultural adaptation of the SATIS-Stroke questionnaire to Brazilian Portuguese. This translation process received authorization from the authors who developed and validated the original questionnaire [15]. The study received approval from the Human Research Ethics Committee of University Nove de Julho, São Paulo, Brazil (certificate number: 74235417.7.0000.5511).


### 2.2. Sample Size

The sample size was determined following the recommendations proposed by Beaton et al. [16], who suggest that 40 individuals be evaluated in the pretest phase of a translated and adapted assessment measure. The analysis of preliminary reliability was based on the recommendations proposed by Hobart et al. [17], who determined a minimum of individuals for reliability studies involving patients with neurological disorders. For the factor analysis, we analyzed the answers of 80 individuals based on a Monte-Carlo simulation study by Barrett and Kline [18], who demonstrated that stable factorial solutions were found with a number ranging from 2 to 3 respondents per item. Thus, as the SATIS-Stroke had 36 items and considering a minimum of two respondents per item, the minimum n for factor analysis would be 72 participants.


### 2.3. Participants

All volunteers who met the inclusion criteria (clinical diagnosis of stroke at least six months earlier, age 20 years or older and hemiparesis) and agreed to participate in the present study signed a statement of informed consent. Individuals with hearing impairment, motor aphasia, comprehension aphasia, and cognitive impairment (based on the results of the Minimental State Examination) [19] were excluded from the study. All individuals were analyzed at the physical therapy outpatient clinics of University Nove de Julho.


### 2.4. Description of SATIS-Stroke

The SATIS-Stroke questionnaire is a fast, low-cost scale with 36 items distributed among the nine ICF domains and is applicable to all patients regardless of sex, age, marital status, affected side of the body, and phase of the poststroke period (acute, subacute, and chronic). The questionnaire is used to assess satisfaction, which regards the individual’s perception of his/her performance in terms of meeting his/her needs during activities and situations of daily living. Such self-reported information assists in the planning of the rehabilitation process. Each item has four response options (very satisfied, satisfied, dissatisfied, and very dissatisfied). “Very dissatisfied” indicates that the individual is unable to perform the activity. “Dissatisfied” indicates that the individual is able to perform the activity, but not without assistance. “Satisfied” indicates that the individual is able to perform the activity alone, but with difficulty. “Very satisfied” indicates that the individual is able to perform the activity alone and with no difficulty. The items are scored from 0 to 3 points and the total ranges from 0 to 108 points, with higher scores denoting greater satisfaction with regard to activities and participation. Activities never performed or not performed in the previous month receive no score and are marked as "not applicable" [the respondent should select the question mark among the response options on the scale (see Supplementary Material)].


### 2.5. Procedures

#### 2.5.1. Translation and Cross-Cultural Adaptation

The translation and cross-cultural adaptation of SATIS-Stroke were performed following internationally recommended guidelines [16] and consisted of six phases (Figure 1).Figure 1
Steps of SATIS-Stroke translation and cross-cultural adaptation process.According to the recommendations proposed by Beaton et al. [16], the first step of the translation and cross-cultural adaptation process consists of the initial translation. In this phase, SATIS-Stroke was translated into Portuguese by two Brazilian translators fluent in both English and Portuguese. Translator 1 was informed with regard to the concepts on the questionnaire and Translator 2 was not informed. The two translators generated two independent versions of the questionnaire (T1 and T2).In the second phase, the two translators evaluated the translations and synthesized a single version (T12). In the third phase, the synthesized version was back-translated into English by two translators fluent in both Portuguese and English, producing two independent back-translated versions (BT1 and BT2) for comparison to the original version to determine the validity of the translated version.In the fourth step, the questionnaire was judged by a committee of experts in neurofunctional physical therapy, which was crucial to achieving cross-cultural equivalence. The role of the expert committee was to consolidate the translated versions and create the prefinal version of the questionnaire for the field tests. In the fifth step, a field test was conducted with the prefinal version using a sample of 40 individuals with a clinical diagnosis of stroke, as recommended by the guidelines for the cross-cultural adaptation of self-report measures. [16] The participants answered the translated version of the SATIS-Stroke questionnaire and were then interviewed to discuss their opinions regarding the limitations of the instrument, item by item, and any questions they may have about the scale.In the sixth phase, all reports and the questionnaires filled out by the participants of the field test were presented to the committee along with the translated version to verify that all steps had been followed and that the reports adequately portrayed the process.


#### 2.5.2. Reliability

The preliminary reliability of SATIS-Stroke was evaluated on two occasions. For the determination of intraobserver agreement, test-retest analysis was performed with an interval of seven to 14 days between evaluations. For the determination of interobserver agreement, a second observer applied the questionnaire after a period of seven to 14 days. The minimum interval of seven days was necessary to avoid the memorization of the answers and the maximum interval of 14 days was used to minimize the possibility of a change in the respondent’s satisfaction regarding activities and participation [20].


### 2.6. Statistical Analysis

The Shapiro-Wilk test was used to determine the normality of the data. Parametric data were expressed as mean and standard deviation. Nonparametric data were expressed as median and interquartile range. Categorical variables were described in absolute values and percentage of the total sample. The intraclass correlation coefficient (ICC) and respective 95% confidence intervals were used for the analysis of reliability. Intraobserver and interobserver reliability were tested using the following classification: ICC < 0.40 = weak reliability; 41 to 0.75 = moderate reliability; and > 0.75 = excellent reliability [21, 22].Ceiling and floor effects were calculated based on the percentage of volunteers who had the highest (ceiling) and lowest (floor) scores. These effects are considered when at least 15% of the individuals have the maximum or minimum scores. [20]Cronbach’s alpha (α) was used for the analysis of the internal consistency of the SATIS-Stroke. The coefficients were interpreted as follows 0.90 to 0.95 = very good; 0.80 to < 0.90 = good, 0.70 to <0.80 = fair, 0.60 to < 0.70 = weak, and < 0.60 = unacceptable. [23]Two evaluation methods were employed to analyze whether the data matrix could be submitted to factorization: the Kaiser-Meyer-Olkin (KMO) criterion and Bartlett's Sphericity Test. As a rule for the interpretation of the KMO indices, values lower than 0.5 are considered unacceptable, values between 0.5 and 0.7 are considered mediocre, values between 0.7 and 0.8 are considered good, and values higher than 0.8 and 0.9 are considered very good and excellent, respectively [24]. Principal component analysis with varimax orthogonal rotation was used for the extraction of the data. As the aim of factor analysis is to reduce the number of variables into a smaller number of factors, only factors with aneigenvalue > 2 were retained for analysis [25]. Only items with a factorial load ≥ 0.35 (positive or negative) were included in the factors.The data were analyzed using the SPSS program, version 22, and a 5% level of significance was adopted for all analyses (p < 0.05).

## 3. Results

### 3.1. Characteristics of Participants

Forty-eight stroke survivors were recruited, eight of whom were excluded for aphasia. Therefore, the sample was composed of 40 individuals. Table1 displays the demographic and clinical characteristics of the participants.Table 1

### 3.2. Translation and Cross-Sectional Adaptation

The translation process from phases I to III occurred with the collaboration of four translators (T1, T2, BT1, and BT2). No disagreements were found among the two translators who performed the versions in Portuguese or between the two translators who performed the back-translations into English. All versions were sent to the expert committee. In phase IV, the expert committee decided to change verbs in the gerund to the infinitive for all items on the questionnaire to satisfy the grammar rules of the Portuguese language. Some words were changed to achieve semantic and conceptual equivalence. For example, on Item 1 “participating in the preparation of foods and beverages in all circumstances”, the word “circumstances” was changed to “situations” (Table2).Table 2
Items altered to achieve semantic and conceptual equivalence.
Synthesis of translated versions Definitive version 1- Participando no preparo de alimentos e bebidas em todas as circunstâncias. 1- Participar no preparo de alimentos e bebidas em todas as situações . 2- Usando faca, garfo e colher em todas as circunstâncias 2- Usar faca, garfo e colher em todas as situações . 13- Gerenciando seus rendimentos em todas as circunstâncias. 13- Administrar seus rendimentos em todas as situações . 14- Usando moedas e notas de dinheiro em todas as circunstâncias. 14- Usar moedas e notas de dinheiro em todas as situações . 21- Preencher informações em documentos/formulários em todas as circunstâncias. 21-Preencher informações em documentos/formulários em todas as situações . 23- Movendo-se para fora de sua casa em todas as circunstâncias. 23- Mover-se para fora de casa em todas as situações . 34- Gerenciando suas dores em todas as circunstâncias. 34- Controlar suas dores em todas as situações. ∗ Changed items are in bold.The committee also decided to add or replace some words with synonyms on 13 items of the questionnaire to facilitate its understanding by the Brazilian population. The items that required the use of synonyms are listed in Table3 with the original version in English, the synthesized translated version, and the definitive version established by the expert committee.Table 3

In phase VI, these individuals were asked if they understood all the questions and demonstrated no difficulties understanding the questionnaire in the form that was administered as the prefinal version defined by the expert committee. The final version of the questionnaire is attached (Supplementary Material1).


### 3.3. Preliminary Reliability

Table4 displays the ICC values and mean differences regarding intraobserver and interobserver reliability. Excellent agreement was found in both cases and all results were significant (p = 0.001).Table 4

### 3.4. Internal Consistency and Ceiling and Floor Effect

Items 8, 17, 35, and 36 were those that most addresses activities that were either never performed or not performed in the previous 30 days and were therefore marked as not applicable (N/A). The ceiling and floor effects were higher than acceptable standards (greater than 15%) for some items. Adequate internal consistency was found for the score of the SATIS-Stroke items (Table5).Table 5

### 3.5. Exploratory Factor Analysis

Preliminary analyses of the 36 items on the scale indicated missing data due to the use of the N/A option (not applicable = activity never performed or not performed in previous 30 days). For these missing data, the mean of the respective item was used. Frequency and distribution analyses of the 36 items indicated satisfactory indices with regard to dispersion and kurtosis as well as the absence of univariate discrepant cases.The extraction of the principal components revealed the goodness-of-fit of the correlation matrix regarding the necessary presuppositions for multivariate analysis, such as the absence of multicollinearity and the factorability of the data. The KMO indicator was 0.770. Bartlett's Sphericity Test indicated p=0.001. Therefore, factorization of the data was possible. Values > 0.50 were found in the analyses of commonalities, indicating that the percentage of variance of each variable explained by common factors was higher than 50% in all cases.Consideringeigenvalues> 2 and the scree plot, the decision was made to extract three factors using principal component analysis with varimax orthogonal rotation. Only items with a load ≥ 0.35 (positive or negative) were included in the factors. The extracted components in the analysis explained 45.50% of the total variability in the data. The first factor explained 25.05%, the second factor explained 13.94%, and the third factor explained 6.50%. The saturations of each item in the respective factors are displayed in Table 6 and are arranged based on the factor load rather than their order on the scale. For cases in which an item could pertain to more than one factor, the criterion of the highest saturation values was used first, followed by the semantic content of the item and its pertinence to the previously described factor.Table 6

## 3.1. Characteristics of Participants

Forty-eight stroke survivors were recruited, eight of whom were excluded for aphasia. Therefore, the sample was composed of 40 individuals. Table1 displays the demographic and clinical characteristics of the participants.Table 1

## 3.2. Translation and Cross-Sectional Adaptation

The translation process from phases I to III occurred with the collaboration of four translators (T1, T2, BT1, and BT2). No disagreements were found among the two translators who performed the versions in Portuguese or between the two translators who performed the back-translations into English. All versions were sent to the expert committee. In phase IV, the expert committee decided to change verbs in the gerund to the infinitive for all items on the questionnaire to satisfy the grammar rules of the Portuguese language. Some words were changed to achieve semantic and conceptual equivalence. For example, on Item 1 “participating in the preparation of foods and beverages in all circumstances”, the word “circumstances” was changed to “situations” (Table2).Table 2

## 3.4. Internal Consistency and Ceiling and Floor Effect

Items 8, 17, 35, and 36 were those that most addresses activities that were either never performed or not performed in the previous 30 days and were therefore marked as not applicable (N/A). The ceiling and floor effects were higher than acceptable standards (greater than 15%) for some items. Adequate internal consistency was found for the score of the SATIS-Stroke items (Table5).Table 5

## 4. Discussion

The purpose of the present study was to perform the translation and cross-sectional adaptation of SATIS-Stroke to Brazilian Portuguese, test its preliminary reliability and internal validity, and perform factor analysis of the measure using different samples of stroke survivors. The analysis of the results revealed that the final translated version of the scale is adequate and reliable for use on the Brazilian population.The sample analyzed was predominantly composed of men with a mean age of 57 years and more than 60 months since the occurrence of the stroke event. Among these characteristics, time elapsed since a stroke is the variable that is most related to poststroke participation [2]. No significant differences were found regarding the affected side of the body, but higher frequencies were found of ischemic stroke and married individuals. Mean schooling was 2.5 years. These findings are in agreement with data in previous studies reporting that the population of stroke survivors in Brazil has a low level of schooling [2].During phases I, II, and III, no disagreements occurred during the translation from English into Portuguese. In phase IV (meeting of the expert committee), the main changes in the translation process were performed to achieve semantic and conceptual equivalence on the questionnaire: the word “circumstances” was changed to “situations”. The aim of these changes was to facilitate the understanding of the target population, considering the sociocultural characteristics of Brazilian stroke survivors, who have a low level of schooling [2], as confirmed in the sample analyzed in the present study.In phase IV, 13 of the 36 items on the questionnaire were altered with synonyms to facilitate the understanding on the part of the Brazilian population and to be in accordance with the idiomatic properties of Brazilian Portuguese. When divergences of opinion occurred regarding which synonyms to use, the concepts of the “Activities and Participation” component of the ICF were used as reference, since the questionnaire was designed based on this classification. All changes are displayed in Table3 and occurred to facilitate the interpretation of the questionnaire by Brazilian stroke survivors. Item 27, which was first translated as “using storage space in your house”, was changed to “use spaces in your home to store food, beverages, closed and other objects necessary to daily living”. The aim was to improve the understanding of the item, as the original statement was very broad, which could lead to interpretation errors. Therefore, the decision was made to discriminate what objects could be stored. The choice of these objects was based the description of category d6404 of the “Activities and Participation” component of the ICF.In phase VI, the patients reported no difficulties understanding the items on the translated version of the questionnaire. Upon receiving the explanations regarding the response options at the onset of the evaluation, the participants demonstrated a good understanding and had no difficulties answering the questionnaire.According to Portney and Watkins [26], reliability is the first prerequisite of a measure and regards its consistency. Reliability studies are crucial to determining the variability of a method or assessment tool as well as avoiding interpretation errors regarding the variables before and after an intervention. The translated version of the SATIS-Stroke exhibited excellent reliability, as demonstrated by the high levels of intraobserver and interobserver agreement. These findings are similar to those described by Bouffiloux et al. [15], who report excellent test-retest reliability when analyzing the original version of the questionnaire.On Item 8, the evaluators noticed that most of the individuals responded that they did not participate in events involving arts and culture. This was likely related to the cultural and socioeconomic level of the volunteers, who were recruited from low-income communities and therefore had restrictions with regard to attending cultural activities and events.The same was found for items 17 “Participating in spousal relationships”; 35 “Maintaining emotional relationships”; and 36 “Having a sexual relationship with somebody”, demonstrating that the sample analyzed has problems with emotional, intimate, and sexual relationships, even though the majority of participants were married. Similar results are described by Silva et al. [27], who analyzed the response theory to the items on the SS-QOL for the evaluation of participation and identified that the most erratic item on the scale was that which addressed the issue of sexual relations. The literature indicates that sexual dysfunction and diminished sexual satisfaction are common among stroke survivors and are associated with physical, psychosocial, and relationship factors [28]. However, these aspects are not adequately addressed in rehabilitation programs for this population. Therefore, these items should not be removed from the SATIS-Stroke questionnaire, since they address important issues regarding satisfaction with interpersonal relationships.The total SATIS-Stroke score did not exhibit ceiling or floor effects, but such effects were beyond acceptable standards for some items. In general, more items had a ceiling effect than a floor effect. It is likely that the chronic nature of a stroke led to greater acceptance and adaptation on the part of the participants, leading to higher satisfaction scores. Silva et al. [9] report similar findings. Despite these ceiling and floor effects for some items, all items on the SATIS-Stroke demonstrated excellent internal consistency (Cronbach’s α: 0.90 to 0.95), which lends further support to the internal reliability of the SATIS-Stroke.In general, the 36 items on the SATIS-Stroke questionnaire are related to the nine domains of the "Activities and Participation" of the ICF. However, principal component analysis led to the extraction of three factors that aggregated more of one construct to each of the factors identified. Considering the semantic content of the items and the relationship between the SATIS-Stroke questionnaire and the ICF, the first factor regards activities of personal care, mobility, home life, and the main aspects of life; the second factor addresses issues regarding community, social and civic life, learning, and the application of knowledge as well as general tasks and demands; and the third factor regards communication, interactions, and interpersonal relationships.Despite the important information presented, this study has limitations that should be pointed out. As a preliminary study, the sample size was not large and the results should therefore be interpreted with caution. Further studies are needed for a more in-depth examination of the validity and reproducibility of the SATIS-Stroke questionnaire using a larger sample. Despite these limitations, the study provides the translated and adapted version of an important measure used in both clinical practice and scientific research, thereby contributing to a better evaluation and therapeutic follow up of stroke survivors.


## 5. Conclusion

The final Brazilian version of the SATIS-Stroke questionnaire exhibited adequate semantic, idiomatic, cultural, and conceptual equivalence to the original version as well as adequate preliminary reliability. These findings demonstrate that SATIS-Stroke is a promising assessment tool for the evaluation of satisfaction among stroke survivors with regard to activities and social participation. However, studies addressing the validation and other properties of this questionnaire are currently underway to enable a more accurate analysis.
