Development And Validation

A valid and reliable instrument is needed to assess the implementation of a program known as ‘Program Guru Penyayang’ in schools. The purpose of this study is to develop the instrument and validate it. The instrument is in the form of a questionnaire distributed to a sample of 230 primary school teachers teaching Orang Asli students. The content validity is assessed by the experts and the construct validity is measured by Exploratory Factor Analysis. The reliability of the instrument is measured using internal consistency reliability, which is an alpha coefficient reliability of Cronbach Alpha. Results of Exploratory Factor Analysis suggested that 23 items need to be removed due to their non-dimensionality as they have more or less equal loadings on several factors. Thus, the final draft of the instrument contains 46 items which are valid and reliable. It yielded high values of internal consistency as reflected by the Cronbach alpha values. Even though the validity and reliability of the instrument are within the acceptable range, more data need to be gathered using bigger sample size, and further analysis using confirmatory factor analysis could be used to explore deeper into the psychometric characteristics of the items before the instrument can be finalized.

The concept of providing a safe internet refers to an attempt to prevent and protect against the damages that may come from any possible harmful content, person and entities in the internet environment. Nowadays in the face of increasing internet use, it is important for individuals who have children to provide safe internet use to their children in terms of preventing their children from being psychologically and socially affected negatively. Therefore, it is very important to develop a scale in order to see the competence of parents in providing safe internet. Purpose of this study is to develop Parent's Safe Internet Providing Competency Scale and to examine its validity and reliability. This research was conducted on a total of 422 participants, 289 females and 133 males, aged between 18 and 59. In process of developing this scale, a 23-item pool was created first and then these items were examined in terms of their grammar, intelligibility, and whether they really measure recognition in couple relationships, and a 20-item application form was obtained in the end. Corrected item-total correlation coefficients were calculated for item analysis of scale. Construct validity of scale was examined by exploratory factor analysis and its reliability with Cronbach alpha internal consistency reliability coefficient. Validity and reliability analyzes were made with SPSS 18. As a result of exploratory factor analysis applied for construct validity of scale, a one-dimensional and 20-item measuring tool with an eigenvalue of 11.3 was obtained explaining % 57 of total variance. KMO sample fit coefficient of scale was found to be .96. Factor loads of scale were ranged between .59 and .84. Cronbach alpha internal consistency reliability coefficient was found to be .96. Corrected item-total correlation coefficients of scale range from .55 to .82. These results show that scale is a valid and reliable measurement tool.

Abstract As curricula to improve medical students' attitudes toward people with disabilities are developed, instruments are needed to guide the process and evaluate effectiveness. The authors developed an instrument to measure medical students' attitudes toward people with disabilities. A pilot instrument with 30 items in four sections was administered to 342 medical students. Internal consistency reliability and factor analysis were conducted. The Cronbach's alpha coefficient was 0.857, indicating very good internal consistency. Five components were identified: comfort interacting with people with disabilities, working with people with disabilities in a clinical setting, negative impressions of self-concepts of people with disabilities, positive impressions of self-concepts of people with disabilities, and conditional comfort with people with disabilities. The instrument appears to have good psychometric properties and requires further validation.

Advance Care

Background: Although patients prefer that physicians initiate advance care planning (ACP) conversations, few physicians regularly do so. Physicians may be reluctant to initiate ACP conversations because they lack self-efficacy in their skills. Yet, no validated scale on self-efficacy for ACP exists. Our objective was to develop a scale that measures physicians’ ACP self-efficacy (ACP-SE) and to investigate the validity of the tool. Methods: Electronic questionnaires were administered to a random sample of family medicine physicians (n = 188). Exploratory factor analysis was performed to determine whether the scale was multidimensional. An initial assessment of the scale’s validity was also conducted. Results: The exploratory factor analysis indicated that a single factor was appropriate using all 17 items. A single, unidimensional scale was created by averaging the 17 items, yielding good internal consistency (Cronbach α = 0.95). The average scale score was 3.94 (standard deviation = 0.71) on a scale from 1 to 5. The scale was moderately correlated with a global single-item measure of self-efficacy for ACP ( r = .79, P < .001), and the scale differentiated between physician groups based on how much ACP they were doing, how recently they had an ACP conversation, formal training on ACP, and knowledge of ACP. In a multivariate analysis, the ACP-SE scale was a strong predictor of the percentage of patients with chronic life-limiting diseases with whom the physician discussed ACP. Conclusion: The final ACP-SE scale included 17 items and demonstrated high internal consistency.

Background: Sleep disturbance is common among hospitalized patients. However, sleep promotion is not a high priority for most healthcare providers, which potentially impacts quality of care. Due to a paucity of validated tools to assess sleep promotion, little is known about the relationship between sleep promotion and quality of care. This study was conducted to assess the validity and reliability of a newly-developed instrument, the Sleep Promotion Questionnaire, and to examine sleep promotion as a predictor of quality of care. The Sleep Promotion Questionnaire includes dimensions of attitude, control, unit norms, intention, and behavior that are associated with sleep promotion. Methods: A total of 302 nurses participated in an online survey. The survey included the initial 36-item Sleep Promotion Questionnaire, a quality of care question, Caring Behavior Inventory, and Professional Quality of Life scale. An exploratory factor analysis was performed to determine the factor structure of the Sleep Promotion Questionnaire. The internal consistency reliability as well as the convergent and divergent validities was assessed. Pearson’s correlations and hierarchical multiple regression procedures were performed to explore the predictors of perceived quality of care. Results: Exploratory factor analysis of the Sleep Promotion Questionnaire yielded 28 items in five subscales, comprising Attitude, Control, Unit Norms, Sleep-aid Intention, and Behavior. Convergent and divergent validities were supported ( r = 0.37; r = −0.38, respectively). The Cronbach’s alphas of internal consistency reliabilities of the Sleep Promotion Questionnaire subscales ranged from 0.70 to 0.89. Regression models showed that sleep-promoting Unit Norms was the only significant predictor of perceived quality of care among both ICU and non-ICU nurses ( β = 0.40; β = 0.28, respectively). Conclusion: The Sleep Promotion Questionnaire appears to be a reliable and valid instrument with satisfactory psychometric properties for assessing sleep promotion, and it seems that having unit norms conducive to sleep promotion may positively impact the quality of care. However, further studies are needed to confirm these results.

The objective of this research was to use the technique of Exploratory Factor Analysis (EFA) for the adequacy of a tool for the assessment of fish consumption and the characteristics involved in this process. Data were collected during a campaign to encourage fish consumption in Brazil with the voluntarily participation of members of a university community. An assessment instrument consisting of multiple-choice questions and a five-point Likert scale was designed and used to measure the importance of certain attributes that influence the choice and consumption of fish. This study sample was composed of of 224 individuals, the majority were women (65.6%). With regard to the frequency of fish consumption, 37.67% of the volunteers interviewed said they consume the product two or three times a month, and 29.6% once a week. The Exploratory Factor Analysis (EFA) was used to group the variables; the extraction was made using the principal components and the rotation using the Quartimax method. The results show clusters in two main constructs, quality and consumption with Cronbach Alpha coefficients of 0.75 and 0.69, respectively, indicating good internal consistency.

AimThe aim of this study was to adapt the Chinese version of Hospital Nursing Department Disaster Preparedness Scale (HNDDPS) and evaluate the psychometric properties among hospital nurses in China. Two specific objectives were (1) to adapt the HNDDPS from Sadiq’s Organisational Disaster Preparedness Scale (SODPS) to fit the context of Chinese hospital nursing system and (2) to establish its validity and reliability.DesignInstrument design study.Settings and participants2657 nurses belonging to 50 nursing organisations of tertiary hospitals spread across seven administrative regions of China.MethodsWe adapted the Chinese version of HNDDPS through translation of the SODPS, back translation and cultural adaptation. Subsequently, we evaluated the validity of the scale through exploratory factor analysis and confirmatory factor analysis (CFA), each performed on half of the original sample. We also evaluated the internal consistency reliability of the scale.ResultsThe Chinese version of HNDDPS comprised five dimensions, with 72 items. Exploratory factor analysis yielded five factors explaining 61% of the items’ variance. CFA confirmed five dimensions of the scale and produced appropriate Goodness of Fit Indexes. Cronbach’s α-coefficient was 0.930 for the total scale and ranged from 0.908 to 0.964 for the five dimensions of the scale.ConclusionHNDDPS demonstrates good internal consistency and construct validity. It is a promising, valid and reliable tool for nurses and nursing managers to evaluate hospital nursing department disaster preparedness.
