“…It has good reliability (Cronbach alpha = 0.757) and validity (accumulative contribution rate = 63.5%). Gunawan & Marzilli [ 26 ] reported that construct validity may not be necessary if the translation process was accurate. In this study, the back-translation method and a translation equivalence evaluation completed by expert panel members were used to ensure the translation accuracy.…”

“…In general, there are a variety of recommended sample sizes for test–retest reliability. The recommended sample size ranged from 50 to over 1000 subjects or the item to response ratio was from 1:3 to 1:20 [ 26 ]. Perneger et al [ 27 ] noted that a sample size of 30 could achieve a power of 80% to detect a problem that occurs in 5% of population.…”

Purpose Nurses play a key role in educating people about a salt-reduced diet to prevent or manage hypertension or cardiac failure. Assessment tools such as the Chinese Determinants of Salt-Restriction Behaviour Questionnaire (DSRBQ) can provide essential evidence to inform education strategies. This study aimed to translate the DSRBQ into English and evaluate the psychometric properties of the Chinese and English versions for people of Chinese ethnicity in Australia. Methods A two-phase cross-sectional descriptive study was conducted. Phase 1: The questionnaire was translated into English using the back-translation method. The translation equivalence and content relevance were evaluated by an expert panel. Three items were revised and eight items were removed. Phase 2: Internal consistency and stability of the questionnaires were evaluated by a group of Chinese Australians. Results Both the English and Chinese versions had satisfactory psychometric properties. In phase 2, 146 participants completed the questionnaire (test), and 49 participants completed the retest. The Cronbach’s alpha scores were 0.638 and 0.584 respectively, and the overall intra-class correlation coefficients were 0.820 and 0.688 respectively for the English and Chinese versions. The Item-Content Validity Index (CVI) ranged from 0.50 to 1.00. The Scale-CVI was 0.94. Conclusion The DSRBQ has been translated into English. Both English and Chinese versions have acceptable validity and reliability. The tools can be used in people from a Chinese cultural background living in Australia. Further validation testing may allow the tools to be adapted for use with other Chinese diaspora groups. The validated DSRBQ will support the development of evidence-based salt reduction nursing assessment tool and interventions for Chinese diasporas who reside in a country where Chinese cultural practices are employed by a minority.

“…In deductive method, items development for a scale depends upon review of related and relevant literature as well as in depth assessment of existing scales (Hinkin, 1995). The researcher may utilize existing literature, interviews of the experts of related filed, or Delphi technique, or a blend of existing literature and interview may be used for item development purpose (Gunawan et al, 2021). The researchers used blend of both inductive and deductive methods for generation of themes and items during current study for development of Teachers' Performance Appraisal Scale (TPAS).…”

The purpose of research in hand was to develop and validate Teachers’ Performance Appraisal Scale (TPAS) to appraise the performance of public primary school teachers of Punjab (Pakistan). The five distinctive dimensions of performance through TPAS were teaching-learning, classroom management, assessment, teacher-student relationship and staff collaboration. Data were collected from 1080 male and female public primary school teachers from nine districts with low, average and high school performance. The experts’ opinion was also incorporated in order to enhance content validity of TPAS. The reliability coefficient of TPAS was observed as (α=.915). The current TPAS comprised on 28 statements. Confirmatory Factor Analysis (CFA) and Exploratory Factor Analysis (EFA) were also carried out. The factor loading of all factors and items were above the threshold value 0.50. The findings of said research indicate that current TPAS is valid and capable in order to appraise performance of public primary school teachers. It is recommended that TPAS may be used by the authorities for teachers' appraisal for the improvement of quality of teaching and learning in primary schools.

“…The sample for the pre-test consisted of nurses from both hospitals, randomly selected according to the inclusion and exclusion criteria: being a nurse and working on clinical inpatient units for adults, while nurses on vacation or leave during data collection were excluded. The final sample totaled 20 participants (nine from Hospital A and 11 from Hospital B), which corresponds to the recommended number of 15 to 30 subjects in the pretesting stage (22) .…”

Objective: To develop and validate the content of a measurement instrument to assess the quality of care transitions and patient safety at hospital discharge from the nurses' perspective. Methods: A methodological study developed in southern Brazil between April 2019 and January 2022, in three stages: integrative review and semi-structured interviews with six nurses for construction of the instrument; content validation with a committee of 14 experts; and a pre-test with 20 nurses. A Content Validity Index above 0.80 was employed. Results: A measurement instrument with 37 items organized into six domains was developed, as follows: structure; discharge planning; care education; referral for continuity of care; safety culture, and care transitions results. The general Content Validity Index reached 0.93. Conclusions: The measurement instrument presented content validation and will contribute to understanding transitional care in the Brazilian context, proposing changes to qualify and strengthen patient safety at hospital discharge.
