Black Sample

Principal components factor analysis of the Physical Self-efficacy Scale and measures of cardiorespiratory function, flexibility, muscle strength and endurance, and a rating of perceived health were calculated for a sample of 138 black undergraduates. Physical Self-efficacy Scale scores were organized into a factor that represented outcomes of fitness in support of the construct validity of the test. Additional evidence of validity was found in application of multiple regression analysis which indicated that nondominant hand-grip strength and sit and reach were significant physical predictors of efficacy scores. We discuss implications of this research for health educators.

In this chapter, 168 anthropometric dimensions and the back-leg-chest (BLC) strength as the muscle strength of 113 male farmers and 31 female farmers of Odisha are statistically analyzed. Factor analysis is done to identify the most significant anthropometric dimensions. Then correlation coefficient and regression analysis are done considering the anthropometric dimensions and BLC strength. Further, an attempt is made by using ANFIS tool to predict the BLC strength of both male and female farmers. It is found that ANFIS could better predict the muscle strength of farmers.

The BCSES-P will demonstrate an internal consistency coefficient of 0.70 or above. Construct validity of the BCSES-P will be demonstrated by support of the following theoretical relationships: Cancer-related self-efficacy will be positively related to marital satisfaction and sexual functioning (social well-being) and the distal outcome, overall QoL. Cancer-related self-efficacy will be negatively related to fatigue (physical well-being), fear of recurrence, depression, and anxiety (psychological well-being). DISCUSSION/SIGNIFICANCE OF IMPACT: Findings will guide intervention development to improve partners’ quality of life The BCSES-P will be the first scale to measure partners’ cancer-related self-efficacy. This study will highlight a holistic approach to studying the long-term effects of breast cancer on partners.

And Performance

This article reports initial evidence of construct validity for a four-factor measure of attributions assessing the dimensions of controllability, stability, globality, and universality (the CSGU). In Study 1, using confirmatory factor analysis, factors were confirmed across least successful and most successful conditions. In Study 2, following less successful performances, correlations supported hypothesized relationships between subscales of the CSGU and subscales of the CDSII (McAuley, Duncan, & Russell, 1992). In Study 3, following less successful performances, moderated hierarchical regression analyses demonstrated that individuals have higher subsequent self-efficacy when they perceive causes of performance as controllable, and/or specific, and/or universal. An interaction for controllability and stability demonstrated that if causes are perceived as likely to recur, it is important to perceive that causes are controllable. Researchers are encouraged to use the CSGU to examine main and interactive effects of controllability and generalizability attributions upon outcomes such as self-efficacy, emotions, and performance.

Background Self-efficacy appears to be an important predictor of functional recovery for women with urinary incontinence, but no specific Spanish-language questionnaires for measuring pelvic-floor exercise self-efficacy exist. Objective The aim of this study was to design a valid and reliable Spanish version of the Broome Pelvic Muscle Self-Efficacy Scale to measure self-efficacy, as perceived by women with urinary incontinence, in performing pelvic-floor exercises. Design This was an observational validation study. Methods Translation-back translation was used to design the survey, and then the survey was validated with a sample of 119 women who were incontinent and had undergone a pelvic-floor exercise training program. The reliability and construct validity of the questionnaire were assessed. Descriptive statistics were used to score the questionnaire. Internal consistency was evaluated with the Cronbach alpha coefficient and the Pearson correlation coefficient. Exploratory factor analysis with both the principal components extraction method and the varimax rotation method was used to assess construct validity. Results The reliability coefficient (Cronbach alpha=.91) and the correlations among items were high. The factor analysis revealed that 6 main factors accounted for 75.8% of the variance. Limitations Conclusions regarding the validity of the questionnaire should be drawn with caution because of the inability to assess criterion-related validity. Conclusions The Spanish version of the Broome questionnaire for self-efficacy appears to be useful as a measuring tool for a psychometrically accurate, clinically relevant estimation of women's self-efficacy in performing pelvic-floor exercises.

Objective. The aims of this study were to translate and psychometrically evaluate the Thai version of diabetes management self-efficacy scale (T-DMSES) and to examine its association with HbA1c control in diabetic individuals. Methods. This study recruited patients from outpatient diabetes clinics of both community and university hospitals. The first phases of this study involved translation of the existing DMSES into Thai, and in the second phase, we evaluated its psychometric properties. The construct validity was evaluated using confirmatory factor analysis. Criterion validity of DMSES was subsequently evaluated by examining DMSES’s association with HbA1c control. Results. The T-DMSES contains 20 items across four factors. Confirmatory factor analysis demonstrated the construct validity of T-DMSES (χ2=645.142, df = 164, p<0.001, CFI = 0.98, RMSEA = 0.065, TLI = 0.977, and AGFI = 0.981). The T-DMSES was also shown to be criterion valid with most subscales highly associated with HbA1c control. Conclusion. The T-DMSES was shown to have good psychometric properties. It is likely to provide valuable insights into the epidemiology of diabetes management self-efficacy and may also prove useful in evaluating interventions for raising diabetes management self-efficacy, which in turn, improve both patient self-management and blood sugar control.

Background: Although attention has been given to the importance of positivity in the workplace, it has only recently been proposed as a new way in which to focus on organisational behaviour. The psychological resources which meet the criteria for positive organisational behaviour best are hope, self-efficacy, optimism and resilience. Aim: The purpose of this study was to investigate the construct validity of the Psychological Capital Questionnaire (PCQ), with specific reference to its psychometric properties. Setting: The sample included a total of 1749 respondents, 60 each from 30 organisations in South Africa. Methods: A multi-factorial model was statistically explored and confirmed (with exploratory factor analysis and confirmatory factor analysis, respectively). Results: The results support the original conceptualisation and empirically-confirmed factorial composition of Psychological Capital (PsyCap) by four elements, namely Hope, Optimism, Resilience and Self-efficacy. However, the study yielded a three-factor solution, with Hope and Optimism as a combined factor and Resilience and Self-efficacy made up of a reconfigured set of substantively justifiable items (three of the original 24 items were found not to be suitable). The three reconfigured factors showed good psychometric properties, good fit (in support of construct validity) and acceptable levels of convergent and discriminant validity. Recommendations were made for further studies. Conclusion: Based on the results obtained, it seems that the PCQ is a suitable (valid and reliable) instrument for measuring PsyCap. This study could thus serve as a reference for the accurate measurement of PsyCap.

The Tilburg Psychological Contract Questionnaire The Tilburg Psychological Contract Questionnaire C. Freese, R. Schalk & M. Croon, Gedrag & Organisatie, volume 21, August 2008, nr. 3, pp. 278-294. The development of the Tilburg Psychological Contract Questionnaire (TPCQ) is described. Criteria are formulated that psychological contract measures should meet. The theoretical background and the psychological contract items of the TPCQ are described. With exploratory factor analysis five perceived organizational obligation scales are revealed: job content, career development, social atmosphere, organizational policies and rewards. Two perceived employee obligation scales were found: in-role behaviour and extra-role behaviour. A separate violations scale was developed. The psychometric features of the scales (including test-retest reliability) were sufficient. Construct validity was assessed with regression analysis on affective commitment, continuance commitment and intention to turnover. Organizational policies, violations and both perceived employee obligations scales were predictors of affective commitment, intention to turnover and to a lesser extent continuance commitment.

Test Retest Reliability

Background Adequate muscle strength, power, and endurance are important in children's daily activities and sports. Various instruments have been developed for the assessment of muscle function; each measures different aspects. The Functional Strength Measurement (FSM) was developed to measure performance in activities in which strength is required. Objective The study objective was to establish the test-retest reliability and structural and construct validity of the FSM. Design A cross-sectional descriptive study was conducted. Methods The performance of 474 children with typical development on the FSM was examined. Test-retest reliability (n=47) was calculated with the intraclass correlation coefficient (2.1A) for agreement. Structural validity was examined with exploratory factor analysis, and internal consistency was established with the Cronbach alpha. Construct validity was determined by calculating correlations between FSM scores and scores obtained with a handheld dynamometer (HHD) (n=252) (convergent validity) and between FSM scores and scores on the Movement Assessment Battery for Children–2 (MABC-2) (n=77) (discriminant validity). Results The test-retest reliability of the FSM total score ranged from .91 to .94. The structural validity revealed one dimension, containing all 8 FSM items. The Cronbach alpha was .74. The convergent validity with the HHD ranged from .42 to .74. The discriminant validity with MABC-2 items revealed correlations that were generally lower than .39, and most of the correlations were not significant. Exploratory factor analysis of a combined data set (FSM, HHD, and MABC-2; n=77) revealed 2 factors: muscle strength/power and muscle endurance with an agility component. Limitations Discriminant validity was measured only in children aged 4 to 6 years. Conclusions The FSM, a norm-referenced test for measuring functional strength in children aged 4 to 10 years, has good test-retest reliability and good construct validity.

Background: The Nursing Profession Self-Efficacy (NPSE) scale was developed to reflect the characteristics of nursing tasks. This study was conducted to validate the Korean version of the NPSE (K-NPSE) scale. Methods: The NPSE scale with nineteen items was translated into Korean after forward and backward translation according to Devellis’ guideline. For the exploratory factor analysis (EFA), 298 nurses participated and criterion-related validity and reliability were verified. For the confirmatory factor analysis (CFA), 218 other nurses participated. Content validity, criterion-related validity, and internal consistency reliability were examined. Additionally, construct validity was examined. SPSS and AMOS were used for the data analyses. Results: Nineteen items were selected after evaluating the content and cognitive validity and comprised three factors: “Professional (10 items)”, “Advocating (4)”, and “Caring (5)”. Construct validity was supported by the CFA. Criterion-related validity was supported by comparison with the General Self-Efficacy Test (r = 0.43, p < 0.001). Cronbach’s alpha of the K-NPSE was 0.93. Conclusions: Study findings indicate that the K-NPSE could be useful for assessing nurses’ self-efficacy. The K-NPSE may be used as a valuable reference for developing programs or policies that promote nursing professionals. It is expected that continued use of this scale in various clinical settings to further generalize and validate the scale.

Abstract Introduction Clinician time and resources may be underutilised if the treatment they offer does not match patient expectations and attitudes. We developed a questionnaire (AxEL-Q) to guide clinicians toward elements of first-line care that are pertinent to their patients with low back pain. Methods We used guidance from the COSMIN consortium to develop the questionnaire and evaluated it in a sample of people with low back pain of any duration. Participants were recruited from the community, were over 18 years and fluent in English. Statements that represented first-line care were identified. Semantic scales were used to measure attitude towards these statements. These items were combined to develop the questionnaire draft. Construct validity was evaluated with exploratory factor analysis and hypotheses testing, comparing to the Back Beliefs Questionnaire and modified Pain Self-Efficacy Questionnaire. Reliability was evaluated and floor and ceiling effects calculated. Results We recruited 345 participants, and had complete data for analysis for 313 participants. The questionnaire draft was reduced to a 3-Factor questionnaire through exploratory factor analysis. Factor 1 comprised 9 items and evaluated Attitude toward staying active, Factor 2 comprised 4 items and evaluated Attitude toward low back pain being rarely caused by a serious health problem, Factor 3 comprised 4 items and evaluated Attitude toward not needing to know the cause of back pain to manage it effectively. There was a strong inverse association between each factor and the Back Beliefs Questionnaire and a moderate positive association with the modified Pain Self-Efficacy Questionnaire. Each independent factor demonstrated acceptable internal consistency; Cronbach α Factor 1 = 0.92, Factor 2 = 0.91, Factor 3 = 0.90 and adequate interclass correlation coefficients; Factor 1 = 0.71, Factor 2 = 0.73, Factor 3 = 0.79. Conclusion This study demonstrates acceptable construct validity and reliability of the AxEL-Q, providing clinicians with an insight into the likelihood of patients following first-line care at the outset.
