Cross-cultural adaptation and measurement properties of the Dutch knee self efficacy scale (K-SES)
BMC Sports Science, Medicine and Rehabilitation, 2019
Self-efficacy is related to outcome after anterior cruciate ligament (ACL) tears. The Knee Self Efficacy Scale (K-SES) available in Swedish and English, was developed to measure self-efficacy in present (K-SESpresent) and future (K-SESfuture) functioning. The objective of this study was to determine measurement properties of the K-SES in Dutch patients. The K-SES was translated and structural validity, internal consistency, test-retest reliability, and measurement error were assessed in three patient samples: one group completed the questionnaire and additional measures pre-surgery (N = 200), and one group post-surgery (N = 58). The third group (post-surgery) completed the K-SES twice (N = 50). Exploratory factor analysis distinguished two underlying important factors: K-SESpresent and K-SESfuture. However, the distinction was not confirmed in Confirmatory Factor Analysis (CFA). Internal consistency for both subscales was excellent (Cronbach's alpha > .80). Test-retest reliab...

Purpose To translate and cross-culturally adapt the Swedish Knee Self-Efficacy Scale (K-SES) into English and evaluate the measurement properties in a sample of individuals with previous knee injury. Methods Translation, cross-cultural adaptation, and evaluation followed the Beaton multi-step process and COSMIN guidelines. Participants (n = 125) aged 16-60 years with a sport-related intra-articular tibiofemoral or patellofemoral injury within the last 5 years completed the K-SES, Knee Injury and Osteoarthritis Outcome Score, Anterior Cruciate Ligament-Return to Sport After Injury Scale, Tegner Activity Level Scale, and Multi-dimensional Health Locus of Control. Confirmatory factor analysis (CFA) tested a-priori two-factor structure and model fit. Cronbach-alpha, intra-class correlation coefficient (ICC), and absolute reliability (Bland-Altman plots) were calculated. Construct validity was assessed by eight pre-defined hypotheses. A subgroup of participants (n = 42) completed the K-SES twice to assess intra-rater reliability. Results The cross-cultural adaptation generated an English K-SES with face and content validity. The original two-factor structure was rejected based on CFA and a revised solution informed by Exploratory Factor analysis resulted in an adequate fit. All construct validity hypotheses were confirmed. The K-SES showed good internal consistency [Factor (F1: α = 0.96; F2: α = 0.73)], intra-rater reliability (ICC = 0.92), and no systematic bias between repeated measurements. Conclusion The English K-SES is a valid and reliable measure for knee-specific self-efficacy in individuals who have sustained a sport-related intra-articular knee injury in the previous 5 years.

A new instrument for measuring self-efficacy in patients with an anterior cruciate ligament injury
Scandinavian journal of medicine & science in sports, 2006
It has been suggested that self-efficacy belief is of major importance for rehabilitation outcome after sports-related injuries. No instruments are, however, available to evaluate perceived self-efficacy for prognostic and outcome expectations in patients with an anterior cruciate ligament (ACL) injury. Perceived self-efficacy is defined as a judgment of one's potential ability to carry out a task, rather than a measure of whether or not one actually can or does perform the task. The purpose of this study was to develop a reliable and valid instrument for measuring perceived self-efficacy in patients with an ACL injury. A total of 210 male and female patients with an ACL injury were included in this study. The items were generated by health professionals with long clinical experience of patients with an ACL injury and by discussions with patients. After item analysis and item reduction, based on the results from 88 patients, the final 22-item version of the Knee Self-Efficacy Sc...

Purpose Evidence is emerging on the importance of psychological readiness to return to sport after anterior cruciate ligament (ACL) reconstruction. The ACL-Return to Sport after Injury scale (ACL-RSI) is developed to assess this. The aim of the current study was to translate ACL-RSI into Norwegian and examine the measurement properties of the Norwegian version (ACL-RSI-No). Methods ACL-RSI was translated according to international guidelines. A cohort of 197 ACL-reconstructed patients completed ACL-RSI-No and related questionnaires nine months post-surgery. One hundred and forty-six patients completed hop tests and 142 patients completed strength tests. Face and structural validity (confirmative factor analysis and explorative analyses), internal consistency [Cronbach’s alpha (α)], test–retest reliability [Intraclass Correlation Coefficients (ICC)], measurement error [Standard error of measurement (SEM) and smallest detectable change at individual (SDCind) and group level (SDCgroup)...

Purpose: To assess whether patient-reported outcomes (psychological factors, appraisals of knee function and physical activity participation) were associated with satisfaction with knee function after anterior cruciate ligament (ACL) reconstruction. Methods: Participants who were aged 18 to 45 years and a minimum 12 months post-primary ACL reconstruction completed a questionnaire battery evaluating knee self-efficacy, knee-related quality of life, self-reported function, and physical activity participation. Participants' responses to the question: "If you were to spend the rest of your life with your knee just the way it has been in the last week, would you feel… (7-point ordinal scale; 1 = happy, 7 = unhappy)" were categorised as satisfied, mostly satisfied or dissatisfied, and used as the primary outcome. Ordinal regression was used to examine associations between independent variables and the primary outcome. Results: 177 participants were included at an average of 3 years after primary ACL reconstruction. At follow up, 44% reported they would be satisfied, 28% mostly satisfied and 28% dissatisfied with the outcome of ACL reconstruction. There were significant differences in psychological responses and appraisal of knee function between the three groups (P < 0.01), and significantly more people in the satisfied group had returned to their pre-injury activity (58%) compared to the mostly satisfied (28%) and dissatisfied (26%) groups (P < 0.001). Multivariable analysis demonstrated that the odds of being satisfied increased by a factor of 3 with higher self-efficacy, greater knee-related quality of life, and returning to the pre-injury activity. Conclusions: People who had returned to their pre-injury physical activity, and reported higher kneerelated self-efficacy and quality of life were more likely to be satisfied with the outcome of ACL reconstruction.

To explore physical and psychological measures believed to determine patients&amp;amp;amp;amp;amp;amp;amp;#39; perceived self-efficacy in the rehabilitation of patients with anterior cruciate ligament injury. An explorative descriptive study. A total of 116 patients with an anterior cruciate ligament deficient or reconstructed knee. At one visit; 12 months post-injury/reconstruction, patients reported their perceived self-efficacy on the Knee Self-Efficacy Scale. Thirty-nine other measures related to self-efficacy were also documented. A linear regression model was applied to identify determinants of perceived self-efficacy. 40% of the variance in the complete Knee Self-Efficacy Scale was explained by the Lysholm score, Knee Injury and Osteoarthritis Outcome ScoreSport/Recreation, Internal Locus of Control and Locus of Control by Chance. The variance in patients&amp;amp;amp;amp;amp;amp;amp;#39; present perceived self-efficacy was explained to 41% by the same measures. Perceived self-efficacy of future capability was explained to 38% by the variance in the Lysholm score, Knee Injury and Osteoarthritis Outcome ScoreSport/Recreation, TegnerPresent level and Internal Locus of Control. Self-reported symptoms/functions and Internal Locus of Control were the most important determinants of self-efficacy in patients with an anterior cruciate ligament injury. In order to strengthen self-efficacy, these determinants should be considered by the clinicians involved in the rehabilitation.

The aim of this study was to (1) describe psychological outcomes during the first year after an anterior cruciate ligament (ACL) reconstruction and (2) compare psychological outcomes in patients who recover symmetrical muscle function with patients who do not. Methods The included patients had undergone a unilateral ACL reconstruction. Patients with a re-rupture and contralateral ACL injury were excluded. Three groups, based on the results from 5 tests of muscle function 12 months after reconstruction, were created. Three validated questionnaires (the Knee Self-Efficacy Scale; the Knee injury and Osteoarthritis Outcome Score subscale "Quality of Life"; the ACL Return to Sport after Injury scale) and a single question "Have you achieved your goal with rehabilitation?" were analysed in 4 different follow-ups after ACL reconstruction (10 weeks, 4, 8 and 12 months). Means and standard deviations were analysed with standard t tests and reported with 95% confidence intervals. Results A total of 328 patients (120 men, 37%), mean age 27.8 ± 10 years, were included. Patients who did not recover symmetrical muscle function (n = 56; 17%) at the 12-month follow-up reported inferior knee-related self-efficacy and quality of life than patients who recovered symmetrical muscle function (n = 96; 29%) at all follow-ups, except quality of life at 4 months. The proportion of patients who stated they achieved their rehabilitation goal at 12 months was 17% for the entire cohort, 24% for patients who recovered muscle function and 5% for patients who did not recover muscle function. Conclusion Patients who recovered strength and hop symmetry 12 months after ACL reconstruction had superior knee-related self-efficacy and greater quality of life during the whole first year after ACL reconstruction. These results can aid clinicians in the decision-making process by providing knowledge of patients who might need further attention during rehabilitation. Level of evidence III.

Purpose To translate into Spanish and validate the anterior cruciate ligament-return to sport after injury (ACL-RSI) scale, and to evaluate the psychological factors that have the greatest impact on the return to play among Spanish football players. Methods The ACL-RSI was first translated into Spanish by two teams of bilingual experts. At the time of discharge, 114 amateur and semi-professional football players who underwent ACL reconstruction answered a questionnaire regarding demographic and injury-related data, along with the translated ACL-RSI, the Knee Injury and Osteoarthritis Outcome Score (KOOS), the Tampa Scale for Kinesiophobia (TSK-11SV) and the injury-psychological readiness to return to sport (I-PRRS). Statistical analysis included reliability tests (Cronbach's alpha and test-retest), construct validity and exploratory factor analysis. Results The ACL-RSI-Sp showed excellent internal consistency (Cronbach's α = 0.9), temporal stability (test-retest r = 0.9) and significant moderate correlations with the KOOS subscales of symptoms (r = 0.4; p < 0.01), pain (r = 0.4; p < 0.01), daily life (r = 0.4; p < 0.01), "sport" (r = 0.5; p < 0.01) and quality of life (r = 0.6; p < 0.01). Significant moderate and strong correlations were also observed for the ACL-RSI-Sp with the TSK (r = − 0.5; p < 0.01) and the I-PRRS (r = 0.8; p < 0.01), respectively. Confidence in performance (1) and fear and insecurity (2) explained 62.6% of the total variance in ACL-RSI-Sp. Conclusions The ACL-RSI-Sp was a valid and reliable instrument to evaluate the relevant psychological factors in the return to sports of Spanish football players after ACL reconstruction. Players' confidence in performance and fear and insecurity were the most important factors influencing the return to play in this population. Level of evidence Level IV.

Self-efficacy belief may be of major importance for the outcome of rehabilitation after sports-related injuries. A new instrument, the Knee Self-Efficacy Scale (K-SES), was used to evaluate the role of perceived self-efficacy in patients with an anterior cruciate ligament (ACL) injury. The purpose of this prospective exploratory study was to describe the patients' perceived self-efficacy at various times post-injury and surgery, respectively, for responsiveness of the K-SES and to correlate the K-SES score with the patients' subjective symptoms. The purpose was also to describe the influence of gender, age and physical activity on the patients' perceived self-efficacy. Thirty recently injured patients with an ACL-deficient knee and 33 patients who had undergone ACL reconstruction reported their physical activity level and their perceived self-efficacy on four test occasions during a 1-year period. The patients' subjective knee symptoms were documented on two of the test occasions. A significant increase in the K-SES score was seen after injury as well as after surgery, during the course of rehabilitation. Pre-operatively, men's perceived self-efficacy was significantly (P 5 0.013) higher compared with women's self-efficacy. Patients with a high baseline (pre-injury) physical activity level (Tegner 7-10) perceived their self-efficacy as being significantly (P 5 0.005) higher pre-operatively important for perceived self-efficacy according to and Crossman . found a relationship between self-efficacy and functional performance in older Scand J Med Sci Sports

Background: This study aimed to produce the Indonesian version of the Anterior Cruciate Ligament-Return to Sport After Injury (ACL-RSI) questionnaire and determine the value of content validity, construct validity, known-groups validity, and internal consistency reliability. Methods: First, the ACL-RSI questionnaire was translated through a cross-cultural adaptation process. Six experts in related fields assessed the adapted questionnaire by giving scores on four criteria: relevance, clarity, simplicity, and ambiguity, which will be calculated into content validity value. Seventy-one participants who experienced ACL injury because of sporting activities and had undergone reconstruction who joined the online community for Knee Injury Patients Support Group filled out the ACL-RSI to determine the known-groups validity and internal consistency reliability. The participants also filled out the Indonesian version of the Knee Injury and Osteoarthritis Outcome Score (KOOS) as a comparison ...
