BACKGROUND: The capability set for work questionnaire (CSWQ) is being used to measure the new model of sustainable employability building on the capability approach. However, previous studies on the psychometric properties of the instrument are limited and cross-sectional. This two-way study aimed to (1) evaluate the convergent validity of the CSWQ with the theoretically related constructs person-job fit, strengths use, and opportunity to craft and (2) test the predictive and incremental validity of the questionnaire for the well-established work outcomes, including work ability, work engagement, job satisfaction, and task performance.METHODS: A representative sample of 303 Dutch workers, chosen with probably random sampling, were surveyed using a one-month follow-up, cross-lagged design via the Longitudinal Internet Studies for the Social Sciences panel. The convergent validity was assessed by exploring the strength of associations between the capability set for work questionnaire and the theoretically related constructs using Pearson's correlations. The predictive and incremental validity was evaluated by performing a series of linear hierarchical regression analyses.RESULTS: We found evidence of the convergent validity of the capability set score by moderate correlations with person-job fit, strengths use, and opportunity to craft (r = 0.51-0.52). A series of multiple regression analyses showed that Time 1 capability set score and its constituents (i.e., importance, ability, and enablement) generally had predictive and incremental validity for work ability, work engagement, job satisfaction, and task performance measured at Time 2. However, the incremental power of the CSWQ over and above conceptually related constructs was modest.CONCLUSIONS: The findings support the convergent, predictive, and incremental validity of the capability set for work questionnaire with not previously investigated work constructs. This provided further evidence to support its utility for assessing a worker's sustainable employability for future research and practical interventions.
Abstract: Clinicians find it challenging to engage with patients who engage in self-harm. Improving the self-efficacy of professionals who treat self-harm patients may be an important step toward accomplishing better treatment of self-harm. However, there is no instrument available that assesses the self-efficacy of clinicians dealing with self-harm. The aim of this study is to describe the development and validation of the Self-Efficacy in Dealing with Self-Harm Questionnaire (SEDSHQ). This study tests the questionnaire’s feasibility, test-retest reliability, internal consistency, content validity, construct validity (factor analysis and convergent validity) and sensitivity to change. The Self-Efficacy in Dealing with Self-Harm Questionnaire is a 27-item instrument which has a 3-factor structure, as found in confirmatory factor analysis. Testing revealed high content validity, significant correlation with a subscale of the Attitude Towards Deliberate Self-Harm Questionnaire (ADSHQ), satisfactory test-retest correlation and a Cronbach’s alpha of 0.95. Additionally, the questionnaire was able to measure significant changes after an intervention took place, indicating sensitivity to change. We conclude that the present study indicates that the Self-Efficacy in Dealing with Self-Harm Questionnaire is a valid and reliable instrument for assessing the level of self-efficacy in response to self-harm.
The traditional paternalistic approach in health care is increasingly developing towards a patient-centered care (PCC) approach. However, not all patients are able to take advantage of the positive effects of PCC. Inadequate health literacy (HL) is an important limiting factor in the ability of patients to take on an active role and exchange information with their health care provider effectively. A provenly effective approach to improvement of provider-patient interaction and health outcomes is the use of health-related questionnaires. The aim of the research project described within this thesis was to adapt the most frequently-used questionnaire in Dutch physical therapy practice and add information and communication technology to it. A Dutch and Turkish version of the tool called Talking Touch Screen Questionnaire (TTSQ) was developed and evaluated on both usability and validity aspects. The current prototype of the tool does not yet fully solve the problems native and minority patients with low (health) literacy have with completing the adapted questionnaire. Big challenges in future development and testing the TTSQ are the recruitment of vulnerable members of the hard-to-reach native and minority target populations and finding research methods that suit the abilities and needs of these participants. This is expected to be a very challenging, labor- and time-consuming process. On the other hand, having a usable, valid and reliable TTSQ may well save a lot of time and money in both research and clinical practice in the future.
